The conveying device can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross section area, good sealing property, convenience in operation, easiness in maintenance, convenience in closed transportation and the like. The spiral conveyor is divided into a shaft spiral conveyor and a shaftless spiral conveyor in the conveying form, and is divided into a U-shaped spiral conveyor and a tubular spiral conveyor in the appearance. The shaftless screw conveyor is suitable for dry powder materials and small particle materials without viscosity (such as cement, fly ash, lime, grains and the like), while the shaftless screw conveyor is suitable for materials with viscosity and easy winding. The working principle of the screw conveyer (such as sludge, biomass, garbage and the like) is that a rotating screw blade pushes materials to convey the materials by the screw conveyer, and the force which prevents the materials from rotating together with the screw conveyer blade is the self weight of the materials and the frictional resistance of a shell of the screw conveyer to the materials. The surface type of the spiral blade welded on the rotating shaft of the spiral conveyor is solid surface type, belt surface type, blade surface type and other types according to different conveyed materials. Screw conveyer's screw axis has footstep bearing in order to give the axial counter-force of spiral along with the material at material direction of motion's terminal, in the longer term of length, should add the middle bearing of hanging, current screw conveyer's feed inlet and discharge gate all can't adjust and the control flow, easily cause the too much equipment damage that leads to the fact of raw materials in the screw conveyer, lead to the fact wearing and tearing to the motor, and some great of raw materials granule of injection molding machine, easily cause screw conveyer discharge gate and injection molding machine funnel to block up, screw conveyer should adapt to different environmental demands simultaneously.
