Description

Novel screw conveyer

Technical Field

The utility model relates to the technical field of mechanical equipment, especially, relate to a novel screw conveyer.

Background

The screw conveyer is a machine which utilizes a motor to drive a screw to rotate and push materials so as to realize the conveying purpose. The conveying device can convey horizontally, obliquely or vertically, and has the advantages of simple structure, small cross-sectional 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. The end of the screw shaft of the screw conveyor in the material moving direction is provided with a thrust bearing so as to provide axial counterforce to the screw along with the material, and when the screw shaft is longer, a middle hanging bearing is added. The screw conveyer in the prior art only conveys materials, but cannot crush the materials when the volume of the materials is large, so that a discharge hole is easily blocked.

In order to solve the above problems, a novel screw conveyor is proposed in the present application.
