All screw chain scraper conveyor, equipment has a hidden danger when conveying powdery materials, which is to prevent dust explosion. Screw chain scraper conveyor, also have such hidden dangers. It is normal for powdery materials to fly dust during the transportation process, and the air diffuses and floats to form dust clouds. Coupled with the air inside the equipment, once it encounters a fire source, the possibility of explosion is not without.
In order to prevent the emergence of this environment, the manufacturing precision of the equipment deployment is relatively high, and it is necessary to prevent the occurrence of sparks caused by friction of parts and components. As the cause of dust explosion is huge and the conditions of the production process are changeable, corresponding protective measures are adopted for different environments.
The closed technology has high requirements for the strength of the equipment, and the equipment has the ability to withstand the large explosion pressure of dust without deformation. In the screw conveyor, the upper and lower cover plates are firmly welded with thicker steel plates, forming 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 installed on the material conveying pipeline to achieve an explosion-proof effect.
Regardless of the materials scraper chain conveyor by the scraper conveying equipment, the regulations on the use of the scraper chain conveyor equipment shall be followed, and prohibited items shall not be done. In order to extend the useful life of the equipment deployment, regular maintenance should be conducted.
