Description

Screw conveyer

Technical Field

The utility model discloses be applied to industrial field, specifically be a screw conveyer.

Background

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. A thrust bearing is arranged at the terminal of a screw shaft of the screw conveyor in the material moving direction so as to provide axial counterforce to the screw along with materials, and when the screw shaft is longer, a middle hanging bearing is added, but the screw conveyor is easy to break in the traditional production process.
