All screw conveyor equipment has a hidden danger to solve when conveying powder materials, which is to prevent dust explosion. The screw conveyor also has such hidden dangers. It is normal for powder materials to fly in the process of transportation. The air diffuses and floats to form a dust cloud. Coupled with the air inside the equipment, once it encounters a fire source, the possibility of an explosion is not impossible.
In order to prevent the emergence of such an environment, the manufacturing accuracy requirements of the equipment deployment are relatively high, and the occurrence of sparks due to friction of parts should be prevented. Due to the huge causes of dust explosions and the changing conditions of the production process, it is necessary to adopt corresponding protection steps for poor environments.
The sealing technology has higher requirements on the strength of the equipment, and the equipment has the ability to withstand the dust explosion pressure without deformation. In the screw conveyor, the upper and lower cover plates are welded with thicker steel plates to form a closed space. If explosion-proof measures are adopted on the connecting pipes between the equipment, the production process can be not interrupted, and the fire can be extinguished in time. For example, a flameproof device is placed on the material conveying pipeline, which plays the role of flameproof.
No matter what materials are conveyed by the conveying equipment, the regulations on the use of the conveying equipment should be complied with, and the prohibited matters will never be done. In order to extend the service life of equipment deployment, regular maintenance should be held.
