1、 Equipment introduction
Screw conveyor is a kind of conveying machinery that uses motor to drive screw rotation to push material forward. As one of the flow shop equipment in the production process, it is widely used in chemical industry, grain, food, feed and other industries. As a kind of pneumatic conveying equipment, screw conveyor can not only be used to transport materials, but also be used in some production processes.
2、 How it works
According to the different materials, the blade surface of screw conveyor includes solid surface, belt surface and blade surface. The rotating spiral blade pushes the material to transport. Depending on the weight of the material and the friction resistance of the screw conveyor shell, the material is pushed forward along the bottom of the conveyor trough. The movement of the material in the middle bearing depends on the thrust of the material moving forward behind.
3、 Use advantage
1) The equipment structure is simple and the initial investment cost is low;
2) Reliable work, convenient maintenance and management;
3) Compact size and small floor area;
4) It can realize the sealed transportation, which is conducive to the transportation of easily flying, hot and strong odor materials, reduce the environmental pollution and improve the working conditions of port workers.
5) Easy to load and unload. It can be loaded and unloaded at any point of the conveying route, which is convenient for reclaiming and unloading;
6) It can also make one conveyor transport materials in two directions at the same time, that is, to the center or away from the center.
4、 Routine maintenance
(1) Timely add lubricating oil to bearings, gears, chains and other transmission parts;
(2) After the box conveyor is out of service, check the wear of spiral blade, and repair welding when the wear is serious;
(3) The conveying capacity should not be overloaded, otherwise the material can not be discharged, which will cause the spiral shaft bending and the box expansion;
(4) When the medium pressure is high, we should pay attention to whether the expansion change of the box is free and there is no sticking place, if there is, we should pay close attention to solve it;
(5) In operation, if there is a harsh noise, should cover inspection, troubleshooting.
