Description
Technical Field
The application relates to the field of screw conveyors, in particular to a shaft head device of a screw conveyor and the screw conveyor.
Background
The screw conveyer is a machine which uses a motor to drive a screw to rotate and push materials to realize the conveying purpose. The horizontal conveying device can horizontally, obliquely or vertically convey and has the advantages of simple structure, small cross section area, good sealing performance, convenient operation, easy maintenance, convenient sealing and transportation and the like. Screw conveyors are classified into a shaft screw conveyor and a shaftless screw conveyor in conveying form, and are classified into a U-type screw conveyor and a tubular screw conveyor in appearance. The screw conveyor with the shaft is suitable for non-sticky dry powder materials and small particle materials (such as cement, fly ash, lime, grains and the like); while shaftless screw conveyors are suitable for conveyors made of sticky and easily entangled materials (e.g., sludge, biomass, refuse, etc.). The working principle of the screw conveyor is that the rotating screw blade pushes the material to be conveyed by the screw conveyor, so that the force for preventing the material from rotating together with the screw conveyor blade is the weight of the material and the friction resistance of the screw conveyor shell to the material. The surface type of the spiral blade welded on the rotating shaft of the spiral conveyor has solid surface type, belt surface type, blade surface type and other types according to the different conveying materials. The spiral shaft of the spiral conveyor is provided with a thrust bearing at the terminal of the material moving direction so as to give axial counterforce to the spiral along with the material, and when the machine length is longer, a middle hanging bearing is added.
