Emergency treatment method for stuffy material in vibrating screw conveyor

The screw conveyor is a widely used conveying equipment in minerals, feed, grain and oil, and construction industries. The screw loading conveyor is suitable for horizontal conveying of granular, powder and small lumps of materials, such as horizontal conveying, vertical conveying, etc., and its conveying distance There are a variety of specifications from 2 meters to 70 meters, and can be manufactured according to customer needs. A common fault is blocking. There are many reasons for blocking. The following measures can be adopted to prevent blocking: An anti-blocking valve is opened on the discharge end cover. Strictly implement the operating procedures to achieve no-load starting and no-load parking; to ensure continuous and even feeding. When blocking occurs, because of the accumulation of materials, the anti-blocking door is opened, and the power supply is blocked by the travel switch. Reduce the horizontal size of the central suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the central bearing. Choose various technical parameters reasonably, such as slow speed not too large. Necessary cleaning of the materials entering the conveyor to prevent large or fibrous impurities from entering the machine and causing blockage. Install silo level device and blocking sensor to complete automatic control and alarm. Increase the discharge opening or lengthen the end of the trough to solve the problem of poor discharge or too late to discharge. At the same time, a small anti-rotation blade can be installed at the end of the trough of the discharge port to prevent the end from blocking the material. Screw conveyor is a kind of continuous material conveying machinery. Because continuous conveyors have different working principles, layout characteristics, methods and directions of conveying materials, and a series of other characteristics, there are many varieties. The other type is design variables, which are layout parameters determined by changing requirements in the design. In the design of the screw conveyor, the productivity and power of the screw conveyor are mainly determined based on the nature of the conveyed material, the conveying volume, the conveying distance, the conveying inclination, and the screw speed. There are two main types of design parameters. One is design constants, which are known data determined according to objective laws and specific conditions or predetermined parameters.
