To extend the service life of the dust collector bag in the asphalt mixing plant, maintenance can be carried out from the following aspects:
Daily operation and maintenance
Control operating parameters: strictly control the operating temperature, pressure and air volume of the dust collector to avoid excessively high or low temperature, excessive pressure fluctuations and air volume overload. Generally speaking, the operating temperature of the dust collector in the asphalt mixing plant should be controlled between 120℃-180℃.
Regularly check the cleaning system: ensure the normal operation of the cleaning device, such as the pulse valve, cylinder and other components are fault-free, and the cleaning time and cycle are set reasonably. Regularly check the pressure of the pulse injection system to ensure that the injection pressure is between 0.4-0.6MPa to achieve the best cleaning effect.
Timely deal with leakage problems: Regularly check the sealing of the dust collector, promptly discover and repair leakage points in pipes, flanges, inspection doors and other parts, and prevent dust-containing gas from short-circuiting and wearing the bags.
Regular maintenance
Check the appearance of the bag: Open the dust collector inspection door regularly to check whether the bag is damaged, deformed, blocked or stuck. If a small area of individual bags is found to be damaged, they can be repaired in time; if the damage is serious, new bags need to be replaced.
Clean the surface of the bag: According to the blockage of the bag, compressed air can be used regularly for reverse blowing and cleaning, or special cleaning equipment can be used to clean the surface of the bag to remove dust.
Replace wearing parts: Other wearing parts of the dust collector, such as the filter bag frame, venturi, etc., should also be checked and replaced regularly to ensure the overall performance of the dust collector.
Storage and installation
Proper storage: Unused bags should be stored in a dry and ventilated environment to avoid moisture, rain and direct sunlight to prevent aging of the bag material.
Standard installation: When installing the bag, be careful to avoid contact between the bag and sharp objects to prevent scratches. At the same time, ensure that the bag is firmly installed and well sealed with the flower plate hole to prevent the bag from being worn or falling off due to looseness.
