Description
Technical Field
[0001] The utility model relates to the technical field of screw conveyors, in particular to a sealing device for a screw conveyor. Background Art
[0002] A screw conveyor is a machine that uses a motor to drive the screw to rotate and push materials to achieve the purpose of conveying. The screw conveyor can be placed horizontally, inclined or vertically, and can convey materials to equipment in different directions. The screw conveyor has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance and convenient closed transportation. The screw conveyor can be used to convey non-sticky dry powder materials and small particle materials, and can also convey sticky and easily entangled materials. The working principle of the screw conveyor is that the rotating spiral blades push the material to be conveyed by the screw conveyor. The force that prevents the material from rotating with the screw conveyor blades is the material's own weight and the friction resistance of the screw conveyor casing to the material.
[0003] The screw conveyor may encounter the situation of conveying powder materials during use. When conveying powdered materials, the problem of loose sealing between the screw machine casing and the screw shaft may occur. Powder may leak from the gap between the shaft end and the screw machine casing. The shaft end needs to be better sealed to prevent material leakage and waste of resources. At the same time, traditional packing seals require shutdown and equipment disassembly, which increases labor costs. Utility Model Content
