Description
Technical Field
[0001] The utility model relates to the technical field of screw conveyors, in particular to a screw conveyor with an anti-blocking mechanism. Background Art
[0002] Screw conveyor is a machine that uses a motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance, and convenient closed transportation. Screw conveyors are divided into two types of conveying forms: shaft screw conveyors and shaftless screw conveyors, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. Shaft screw conveyors are suitable for non-sticky dry powder materials and small particle materials. (For example: cement, fly ash, lime, grain, etc.) While shaftless screw conveyors are suitable for conveyors with sticky and easily entangled materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating spiral blade pushes the material to be conveyed by the screw conveyor. The force that prevents the material from rotating with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor casing to the material. The spiral blades welded on the rotating shaft of the screw conveyor have solid surface type, belt surface type, blade surface type and other types according to the different conveying materials. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the screw an axial reaction force along with the material. When the machine is long, an intermediate hanging bearing should be added. When the traditional screw conveyor is used to convey materials with high viscosity, such as sludge, cement and other materials, the material is easy to block the feed hopper of the screw conveyor, and then the material cannot be discharged normally, resulting in obstruction of the screw conveyor, affecting the conveying work, and thus causing the working efficiency of the screw conveyor to decrease.
