How to avoid spontaneous combustion of dust ash of shot blasting machine
Spontaneous combustion of dust blasting blasting machine is a very serious problem, once it occurs, it may cause a fire. Therefore, it is very important to avoid spontaneous combustion of dust blasting blasting machine.
1. When checking the shot blasting unit, the fire source should be strictly controlled, and the circuit should be avoided. When welding, the surrounding dust should be removed first. After the machine is repaired, it can be produced after 10 minutes of commissioning. In order to prevent hot particles or sparks from being sucked into the dust collector, it is strictly prohibited to smoke or ignite other open flames near the shot blasting machine.
2. In order to avoid the classic accumulation of equipment and facilities and increase conductivity, replace highly insulating materials with conductors or conductive materials. Therefore, related equipment should be changed to maintain good grounding. The cloth bag should use the one with better electric resistance.
3. In order to prevent the deposition of rust dust and the generation of sparks due to the accumulation of heat energy, the dust in the dust collector should be removed in time, and the back blowing and unloading of dust should be done regularly.
4. Each user should train the operators and maintenance personnel on theoretical and practical knowledge to make employees realize that rust dust is a flammable product and the simple operation of the dust collector, and pay attention to the operation status of the dust collector at all times during production.
It is very important to do the above four tasks well.
