All screw conveyor equipment has a hidden danger to be solved when conveying chain powdery materials, that is, to prevent dust explosion. Screw conveyors also have such hidden dangers. It is normal for dust to fly during the transportation of powdery materials, and dust clouds are formed by diffusion and floating in the air. Coupled with the air inside the equipment, once encountering the fire source, the possibility of explosion is not without.
In order to prevent the emergence of this environment, the manufacturing accuracy of equipment deployment is required to be higher than the force, so as to prevent parts from friction and spark. As the causes of dust explosion are huge and the production process conditions are changeable, the corresponding protection steps are accepted for the poor environment.
The sealing technology requires high equipment strength, and the equipment can withstand the big explosion pressure of dust without deformation. In the screw conveyor, the upper and lower cover plates are firmly welded with thicker steel plates to form a closed space. If explosion-proof measures are adopted on the connecting pipes between equipment, the production process can not be interrupted and the fire can be extinguished in time. For example, an explosion-proof device is arranged on the conveying pipeline of materials to play the role of explosion-proof.
No matter what materials are conveyed by the conveying equipment, the use regulations of the conveying equipment shall be observed, and the prohibited matters shall not be done. In order to extend the service life of equipment deployment, maintenance and recuperation should be held regularly.
