Product description

Screw conveyor is a kind of machinery that uses a motor to drive spiral rotation and push materials to achieve the purpose of conveying. It can be transported 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 shaft screw conveyors and shaftless screw conveyors in terms of conveying form, and are divided into U-shaped screw conveyors and tubular screw conveyors in appearance. Shaft screw conveyor is suitable for non-sticky dry powder materials and small particle materials. (For example: cement, fly ash, lime, grain, etc.) The shaftless screw conveyor is suitable for conveying viscous and easy-to-wind materials. (For example: sludge, biomass, garbage, etc.) The working principle of the screw conveyor is that the rotating screw 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. 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, belt surface, blade surface and other types according to the different materials to be conveyed. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to give the axial reaction force of the screw with the material. When the length of the machine is long, an intermediate suspension bearing should be added

When the screw shaft rotates, due to the gravity of the material and the friction generated by the wall of the tank, the material can only move forward along the bottom of the conveyor tank under the push of the blades. The rotating screw makes a translational motion. The movement of materials in the middle bearing depends on the thrust of the materials moving forward. Therefore, the transportation of materials in the conveyor is a slipping motion. In order to keep the screw shaft in a more favorable tension state, generally the driving device and the discharge port are placed on the same end of the conveyor, and the feed port is placed as close as possible to the tail of the other end. The rotating screw blade pushes the material for transportation, so that the force that the material does not rotate with the screw conveyor blade is the weight of the material and the friction resistance of the screw conveyor casing to the material. The surface of the blade has solid surface, belt surface, blade surface 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 axial reaction force of the screw with the material. When the length of the machine is long, an intermediate suspension bearing should be added.
