Does the asphalt melting equipment need to be disassembled for movement?

Some of the equipment of emulsified modified bitumen equipment are as follows. The specially made bitumen filter can effectively filter the residues and dirt in the high-temperature culture medium bitumen to avoid damage to the subsequent equipment. The emulsified modified bitumen equipment adopts a spiral plate type or a shell and tube heat exchanger to quickly heat the culture medium bitumen through high-temperature heat transfer oil to meet the needs of the production process. The emulsified modified bitumen equipment is heated in the storage tank to prevent the bitumen from aging due to long-term high-temperature heating and exposure to the air. The sulfate generated during the production process of the emulsified modified bitumen equipment is very limited, reducing air pollution.
The emulsified modified bitumen equipment sends the modified material manually poured into the dumping bin to the bitumen batching tank by wind or spiral. It can be equipped with a metering and calibration system. The emulsified modified bitumen equipment thickener is automatically or manually added. The emulsified modified bitumen equipment can be equipped with a metering and calibration system. Emulsified modified bitumen equipment transportation and metering and calibration system, the emulsified modified bitumen equipment adds the set bitumen amount to the batching tank through the frequency converter and computer interlock. The emulsified modified bitumen equipment and bitumen steam flowmeter use big brand products to ensure the preparation.

I believe that after a long period of contact with asphalt tanks, everyone knows that the working efficiency of emulsified asphalt equipment actually depends on the operator. The more experienced the operator is and the stronger his ability to deal with various emergencies is, the higher the working efficiency will be, and the safety will be guaranteed. Mastering more equipment-related knowledge is what every friend should pursue. Today, the editor will explain to you the details that need to be paid attention to when operating emulsified asphalt equipment:

The slurry sealer is a special equipment for road maintenance that we see in our lives. The slurry sealer is mainly used to deal with the decrease in surface wear resistance, cracks, etc. of the road, to improve the waterproofness and skid resistance of the road surface, thereby greatly improving the driving comfort and flatness inside, so as to achieve a new effect for the road surface. So what is the operation process of the slurry sealer?
Before starting the slurry sealer, you should be prepared to test the quality of the slurry sealer materials before construction. One of the most important points is to certify and inspect whether the content of emulsified asphalt can meet the requirements of the specification, and the mixture should also meet the requirements. After confirming the measurement standards, check that the road surface to be constructed should be dry, free of debris, water, flat, etc.

Asphalt emulsifiers can be divided into synthetic emulsifiers, natural emulsifiers, inorganic powder emulsifiers, etc. according to their formation. Synthetic emulsifiers are currently the most widely used. Asphalt emulsifiers are a type of organically synthesized surfactant that can emulsify asphalt.
Emulsifiers are divided into ionic and non-ionic types according to whether the hydrophilic group of the emulsifier molecule is charged when the emulsifier is dissolved in water. Ionic emulsifiers are divided into cationic and anionic types due to the different charges of the hydrophilic group after ionization in water. In addition, there are zwitterionic types.
Cationic emulsifiers are divided into three types: fast cracking, medium cracking, and slow cracking according to the speed of demulsification. Slow cracking emulsifiers are divided into slow setting and fast setting according to the length of time the mixture solidifies. Slow cracking and slow setting types are mainly used as permeable oils. Slow cracking and fast setting are used for micro-surfacing, slurry sealing, cold regeneration, etc. Medium cracking and fast cracking types are used for adhesive layer oils, gravel sealing layers, and waterproof base oils.

Modified material bitumen stripper, if the definition is simple, is an bitumen stripper. If described in detail, modified materials such as rubber powder or other fillers are added to the bitumen stripper, or an bitumen stripper is used to Block chemical substances such as photooxygen catalysis. The first is to change the chemical composition of the bitumen stripper, and the second is to use modified materials to equip the stripper with a certain spatial network structure, thereby improving its performance. Modified bitumen strippers mainly include vulcanized rubber and thermoplastic polyurethane elastomer modified bitumen strippers, plastic and anti-corrosion coating modified bitumen strippers and polymer modified bitumen strippers.

The container-type emulsified bitumen equipment hot-melts the base cold-mix colored bitumen and disperses it through the equipment into small cold-mix colored bitumen particles in an aqueous solution containing emulsifier to form a liquid cold-mix colored bitumen material.

Here is an introduction to the knowledge on construction quality control of modified rubber asphalt equipment. Let’s introduce this knowledge from three aspects. The details are as follows: The viscosity of the modified asphalt mixture of modified rubber asphalt equipment is relatively high, and the construction temperature of each process is The construction temperature requirements are higher than those of ordinary asphalt mixtures.

Water is one of the raw materials of the modified asphalt storage tank, and it is distributed in various components of the modified asphalt storage tank equipment. According to the components where water is distributed, the anti-cold measures are explained one by one. The water tank of the modified asphalt storage tank, the water inside the water tank is released through the filter valve. Some instruments of the modified asphalt storage tank do not have a filter valve to save the cost of the equipment. The modified asphalt storage tank can only be drained by loosening the flange bolts at the bottom. The water pump of the modified asphalt storage tank mentioned here includes a hot water pump and a circulating water pump. This type of water pump for the modified asphalt storage tank generally uses a pipeline centrifugal pump. There is a sewage outlet at the bottom of the pipeline centrifugal pump. The modified asphalt storage tank pays attention to the sewage treatment of the sewage outlet at the bottom of the pump. The modified asphalt storage tank emulsion tank generally uses a cone bottom. However, in order to better process the modified asphalt storage tank coefficient, the inlet and outlet are usually not placed at the bottom of the modified asphalt storage tank. Emulsion (mostly water) will remain at the bottom of the tank, and this part of the residual liquid in the modified asphalt storage tank must be discharged through the filter valve at the bottom. Emulsion pump for modified asphalt storage tank There are basically two types of emulsion pumps for modified asphalt storage tank equipment on the market, gear pumps or centrifugal water pumps. Gear pumps can only discharge the liquid inside the pump through the connection flange of the pipeline. The centrifugal water pump for modified asphalt storage tanks uses its own sewage outlet for sewage treatment. The first four items of modified asphalt storage tanks with basic knowledge are basically discharged, and the modified asphalt storage tanks will focus on the latter types. Modified asphalt storage tank colloid mill There will also be residual emulsion or water inside the modified asphalt storage tank colloid mill. The gap between the stator and rotor of the colloid mill is within 1mm. If there is a little residual water in the modified asphalt storage tank, it will cause the accident of frozen modified asphalt storage tank. The residue in the colloid mill can be treated by loosening the connection bolts of the finished product pipeline.

Working conditions of asphalt debarreling equipment:
(1) Outdoor temperature: 20°C (average temperature of day and night)
(2) Heat exchange oil: 320 ℃
(3) Loading time is not included (because the personnel equipped in each unit are different, so the loading time is also different)
(4) There is no fluctuation in oil temperature (optimal automatic burner)
(5) The working temperature of the oil furnace is 220-260 ℃
(6) The flow rate of the oil circulation pump is not less than 50m3/h traffic
(7) When the outdoor temperature is lower than 20℃, the output decreases. The lower the temperature, the lower the output, and the higher the temperature, the higher the output.
(8) The greater the deformation of the asphalt barrel, the greater the impact on the output

For each equipment used, certain safety knowledge must be followed. For the use of emulsified asphalt equipment, detailed instructions are given:
1. Placement: The emulsified asphalt equipment should be placed on a flat place, the front axle should be fixed to the sleepers, and the tires should be dangling. The machine should not be fiddled with at will to affect normal operation.
2. Regularly check whether the mixer blades are deformed and the screws are loose.
3. Check whether the running direction of the mixing drum is consistent with the direction of the arrow. Please replace the positive and negative poles of the terminal.
4. Before turning on the power, check the no-load test run, check for air leakage, and check the idling speed of the mixing barrel. The normal speed is about 3 times faster than the empty car. If not, stop the inspection.
5. If the asphalt material is stopped for one hour after mixing, clean the mixing barrel, pour in clean water, and clean the mortar. Then drain the water. Remember that there should be no water in the barrel to prevent the formula from changing, so that the page and other links will rust. Sinoroader will provide you with more safe emulsified asphalt knowledge, please continue to browse.

Summary
There are various methods for highway preventive maintenance construction, and the selection should be based on comprehensive considerations of factors such as the degree of road damage, traffic volume, and climate. Reasonable preventive maintenance can not only extend the life of the road, but also improve driving safety and comfort.

The bitumen (composition: asphaltene and resin) drum melting machine adopts a self-heating integrated structure, which integrates the thermal oil boiler used in the old asphalt drum melting machine and the barrel removal equipment itself, reducing the volume of the entire equipment and significantly It reduces equipment investment (actual significance: it is the accumulation of future profits), saves the space occupied by the equipment and the logistics cost of switching sites. The combustion chamber is placed inside the equipment itself, which greatly reduces thermal damage and improves heat utilization.

Emulsified asphalt equipment is a special equipment for producing emulsified asphalt. The emulsified asphalt produced by emulsified asphalt equipment is used in many industries. I wonder how much you know about the emulsified asphalt produced by emulsified asphalt equipment. Let’s take a look at them one by one:
Slurry seal is a cold mix asphalt mixture with the advantages of aggregate and asphalt mixing. Under normal circumstances, similar graded slurry seal has a higher modulus than hot mix asphalt mixture, so it is often used to fill road rutting. The higher stability has a higher resistance to deformation. The mixture is usually composed of harder fine aggregate grading and wear-resistant aggregate with high sand equivalent, especially micro-seal and polymer-modified seal. This greatly increases the strength and integrity of the road surface. This makes the road surface have high wear resistance and excellent deformation resistance. Emulsified asphalt emulsion is also easy to use on a mobile slurry seal paver, where mixing and admixtures are used for chemical control to meet maintenance needs.

Emulsified asphalt is an emulsion that disperses asphalt into the water phase to form a liquid at room temperature. This determines that emulsified asphalt has many technical and economic advantages over hot asphalt and diluted asphalt. We know that modified asphalt equipment is a road engineering machinery. In order to better promote users’ understanding of it, today the editor will introduce its characteristics to you so that users can better understand that modified asphalt equipment is used for modified asphalt. It consists of a main machine, a modifier feeding system, a finished product tank, a heat transfer oil reheating furnace and a microcomputer control system. The main machine is equipped with a mixing tank, a dilution tank, a colloid mill and an electronic weighing device. The entire production process is controlled by a computer automatic program. In addition, it can be learned that the product has the advantages of reliable quality, stable performance, accurate measurement, and convenient operation. It is an indispensable new equipment in highway construction. The advantages of asphalt equipment are prominently reflected in its two-way modification effect, that is, while greatly increasing the softening point of asphalt, it also significantly enhances the low-temperature ductility, improves the temperature sensitivity, and has a particularly large elasticity and recovery rate. The modified asphalt equipment has a long service life and a safe and reliable production process. The rotor and stator are specially heat treated, and the service life of the equipment is more than 15,000 hours.

After the emulsified bitumen equipment has been used for a long time, it needs maintenance. There are several points to note when adjusting the emulsified bitumen equipment:
1. During use, regular maintenance should be carried out as appropriate according to the processing materials;
2. For the maintenance and use of the motor, please refer to the motor manual;
3. Most of the random spare parts are national standard and department standard parts, which are purchased all over the country;
4. The colloid mill is a high-precision machine with a line speed of up to 20m/second and a very small grinding disc gap. After inspection and reinstallation, the coaxiality error between the housing and the main shaft must be corrected with a dial indicator ≤0.05mm;
5. When repairing the machine, it is not allowed to be directly knocked with an iron bell during the disassembly, reinstallation and adjustment process. Use a wooden hammer or a wooden block to knock gently to avoid damaging the parts;
6. The machine seals: divided into static and dynamic seals. The static seal uses an O-type rubber ring and the dynamic seal uses a hard mechanical combined seal. If the hard sealing surface is scratched, it should be repaired by grinding on flat glass or flat casting immediately. The grinding material should be ≥200# silicon carbide grinding paste. If the seal is damaged or cracked seriously, please replace it immediately.

In order to better play the role of slurry seal vehicles, this article explains the matters that should be noted from the aspects of the scope of application, type and material selection, construction technology, common diseases, etc. of slurry seal vehicles.
The slurry seal vehicle is thin in thickness and mainly plays the role of waterproofing, anti-skid, wear-resistant and improving the appearance of the road surface. In the pavement structure system, it can only serve as a surface protection layer and wear layer, but not a load-bearing structure. It is widely used in the construction and maintenance of highways. Practice has proved that the slurry seal can also play an important role by reasonably selecting the thickness and type of the slurry seal and strictly controlling the construction technology and quality.
(1). The scope of application of slurry seal vehicles includes the following aspects:
1. When the pavement damage index of expressways and first-class highways is evaluated as medium and below, or the pavement damage index of second-class and below highways is evaluated as secondary and below, when medium repair and overlay measures should be taken, slurry seal can be selected.
2. When the pavement driving quality index of expressways and first-class highways is evaluated as medium or below, or the pavement driving quality index of second-class and below highways is evaluated as second or below, medium repair and overlay measures should be taken to improve its flatness, and slurry seal can be selected.
3. For sections of expressways and first-class highways with insufficient anti-skid capacity (SFC<40), or sections of second-class and below highways with insufficient anti-skid capacity (SFC<33.5), measures such as adding overlays should be taken to provide anti-skid capacity of the road surface. 4. Anti-skid layer and waterproof protective layer used for third- and fourth-class highways to improve the appearance of the road surface.

The heating principle of asphalt decanter equipment is to heat, melt and decanter the asphalt through the heating plate. It is mainly composed of de-barreling box, lifting system, propeller and electrical control system.
The box of asphalt decanter plant is divided into upper and lower chambers. The upper chamber is the asphalt melting chamber, which is densely covered with heat transfer oil heating coils or hot air heating pipes. The asphalt is melted and removed from the barrel by heat. The hoisting hook is installed on the gantry, and a barrel grabber is hung. The asphalt barrel is lifted by the electric winch, and then the asphalt barrel is placed on the guide rail by horizontal movement. Then the propeller pushes the barrel into the upper chamber through two guide rails, and an empty barrel is pushed out at the rear end outlet.
An anti-drip oil tank is provided at the entrance of the asphalt barrel. The asphalt enters the lower chamber of the box and is continuously heated to a temperature of about 100 to be transported, and then pumped into the asphalt tank by the asphalt pump. The lower chamber can also be used as an asphalt heating tank.
The asphalt decanter plant has the characteristics of not being restricted by the construction environment, strong adaptability and extremely low failure rate. If large production is required, multiple units can be assembled.

Regarding the basic knowledge of modified bitumen plant, I believe that many consumers have already had a basic understanding of it. Because of the continuous development of various fields today, various facilities including modified bitumen plants have been well developed and applied, and modified bitumen plant has gradually been recognized by customers.
The direct quick heating portable equipment in the modified bitumen equipment not only has a faster heating speed, saves fuel, and is pollution-free, but also convenient and easy to operate. The automatic heating system completely eliminates the trouble of baking or cleaning bitumen and pipelines.

The selection of asphalt melting equipment should take into account factors such as the use environment, working conditions, and technical requirements. Common ones include hot oil heating equipment, electric heating equipment, and gas heating equipment.
Hot oil heating equipment is suitable for occasions that require long-term heating and high temperature control accuracy;
Electric heating equipment is suitable for small projects or occasions where temperature control accuracy is not required;
Gas heating equipment has the advantages of simple operation and low cost, but safety protection measures must be strictly followed.
When choosing, it is also necessary to comprehensively consider factors such as economy and environmental protection.

Modified bitumen equipment is a common road construction equipment. In order to better apply this type of equipment, construction personnel need to be familiar with the performance characteristics of each component and understand its function. Only in this way can the normal use of the equipment be guaranteed in daily applications and its function be maximized.
The main structural components of the standard modified bitumen equipment we have seen in the industry are configured as follows:
1. Filter: Impurities in the hot base asphalt can be filtered to prevent damage to subsequent equipment.
2. Bitumen heater: The jacketed heat exchanger further heats the base asphalt through heat transfer oil to meet the needs of the production process.
3. Modifier air delivery system: The modified agent manually poured into the pouring tank is delivered to the asphalt batching tank by air.
4. Stabilizer automatic suction system: Use negative pressure to suck the stabilizer into the batching tank.
5. Asphalt batching tank: Prepare asphalt mixture according to the formula, and use its combined agitator to ensure uniform mixing.
6. Asphalt transportation system: The prepared asphalt mixture is pumped into the swelling tank through a circulation pump for swelling and development.

Emulsified asphalt equipment improves the fluidity of asphalt: When the emulsified asphalt equipment is subjected to mechanical actions such as high-speed centrifugation, shearing, and impact, the emulsified asphalt equipment makes it into particles with a particle size of 0.1~5μm, and disperses it into a water medium containing a surfactant (emulsifier-stabilizer). Since the emulsifier can be directional adsorbed on the surface of the emulsified asphalt equipment particles, the interfacial tension between water and asphalt is reduced, so that the asphalt particles can form a stable dispersion system in water. The emulsified asphalt equipment is an oil-in-water emulsion.

We should select products that meet the specifications, and we should not select raw materials that do not meet the specifications. The other thing is the operation technology of asphalt heating equipment. Skilled operation technology is the most important, and training is required before taking up the post.
In recent years, with the continuous development of various industries, the production of various equipment including modified asphalt equipment has been further developed and applied. Professionals introduced that in the process of using modified asphalt equipment for production, the terminal control system implements full automatic control of medium weight, working temperature, working flow, valve opening and closing, etc., thereby ensuring the quality of modified asphalt and greatly improving production efficiency. Now Shandong Duxiu Factory will explain the operating advantages of modified asphalt equipment to customers:
The base asphalt is heated to 150-170℃ in the rapid heating tank and then enters the blending tank to mix with the modifier fed in through the feeding device. The asphalt pump at the bottom of the blending tank then sends it to the colloid mill for high-speed grinding and shearing, so that the modifier and base asphalt are fully dissolved in extremely small particles, thereby improving the various properties of the asphalt. The finished modified asphalt after high-speed shearing and grinding enters the finished product development tank at the rear for direct use.

With the rapid development of our country’s social development and the continuous development of economic and information technology, modern highway construction is also developing rapidly, and the requirements for ground structural materials are becoming higher and higher, and Asphalt concrete bonding raw materials are inseparable from modified asphalt equipment. So besides these influencing factors, what other reasons does the company have that people don’t understand? Let’s analyze it together.
There are some asphalt concrete equipment on the market, because they have not solved the problem of asphalt clogging before grinding, there are not enough preparation equipment and grinding equipment, the structure is unscientific, and the entire grinding process cannot achieve a certain particle size, resulting in modification. The product productivity of asphalt equipment is low and the product quality is unstable. It requires continuous grinding for a long time, creating problems. This will not only greatly increase energy consumption, increase costs, make product quality unstable, and affect the speed of highway construction.

I believe that many people already know about synchronous gravel sealing. But when asked under what circumstances synchronous gravel sealing is suitable, many people cannot tell.
Under what circumstances is synchronous gravel sealing more suitable? According to the technical specifications for the construction of simultaneous gravel sealing, simultaneous gravel sealing can be used for the following disease types:

Except for the first application, for enterprises whose block asphalt melting equipment license has expired and continue to engage in the production and operation of block asphalt melting equipment, they should apply for the relevant matters of postponement and renewal 45 working days before the expiration of the license.
The block asphalt melting equipment should first prepare the block asphalt melting equipment application materials, and then submit an application for postponement and renewal to the municipal environmental protection bureau. According to the production and operation of the block asphalt melting equipment and environmental protection work of the applicant enterprise, the municipal environmental protection bureau of the district where the block asphalt melting equipment is located will provide a review opinion in the form of a public document.
For the block asphalt melting equipment, the Provincial Environmental Protection Department will review the application materials, and appoint the Provincial Block Asphalt Melting Equipment Management Office to organize relevant doctors to conduct technical evaluation and on-site technical evaluation, and produce expert technical evaluation opinions and on-site inspection reports. Then report the materials of the block asphalt melting equipment to the meeting of directors for scientific research and make a review decision.

In our daily life, we can often see emulsified asphalt equipment. Its appearance has brought us great convenience. So what is the difference between its modification process? Below, the editor will give you a brief introduction to the relevant knowledge points.
1. Emulsified asphalt equipment first emulsifies and then modifies: This is a relatively simple way to make modified emulsified asphalt. The production process is to grind hot asphalt and emulsifier soap together through a colloid mill to make ordinary emulsified asphalt, and then add latex-like modifiers to the emulsified asphalt through mechanical stirring to make modified emulsified asphalt. The characteristic of this method is that it does not require high equipment.

When emulsifying asphalt, the temperature of asphalt should be controlled above 130℃ to ensure good fluidity; the amount of BE-1, 2, and A1 emulsifiers is generally 8-14‰ of emulsified asphalt, that is, 8-14kg per ton of emulsified asphalt (asphalt content is above 50%), and the temperature is 60-70℃.
The emulsifier should be used in the upper and middle limits of the first production, preferably 10kg per ton of emulsified asphalt, or 20kg per ton of water (asphalt content is 50%); the amount of BE-3 emulsifier is generally 18-25‰ of emulsified asphalt, that is, 18-25kg per ton of emulsified asphalt (asphalt content is above 50%), and the temperature of the emulsifier solution is 60-70℃.
During the first production, the emulsifier should be used in the middle and upper limit dosage to ensure successful production. It is best to use 24 kg per ton of emulsified asphalt, or 48 kg per ton of water (asphalt content is 50%). After the production goes smoothly, the dosage can be reduced according to actual conditions.

The modified asphalt equipment produced by Sinoroader can produce SBS, rubber powder, SBR, and PE modified asphalt manually and automatically. Some of its configurations and uses are as follows:
1. Filter: The specially made asphalt filter can effectively filter impurities and foreign matter in the high-temperature matrix asphalt to prevent damage to subsequent equipment.
2. Matrix asphalt heater: The spiral plate or shell and tube heat exchanger is used to quickly heat the matrix asphalt through heat transfer oil to meet the needs of the production process. Heating in a sealed tank avoids the aging of asphalt due to long-term high-temperature heating and exposure to the air. The sulfide produced during the production process is quite limited, reducing environmental pollution.
3. Modifier air delivery or spiral addition system: The modifier manually poured into the pouring hopper is delivered to the asphalt batching tank by wind or spiral. It can be equipped with a metering system.
4. Stabilizer automatic or manual addition system: It can be equipped with a metering system.
