Working principle of screw conveyor

Source website: Zhengzhou Hongli Machinery Manufacturing Co., Ltd. released time: 2018.05.25 Clicks: second

  Screw conveyor It is a kind of machine which uses the motor to drive the screw to turn the material to achieve the purpose of conveying. It can be horizontally, inclined or vertically conveyed, and has the advantages of simple structure, small cross section area, good sealing performance, convenient operation, easy maintenance, and convenient closed transportation. Screw conveyor in the form of transport can be divided into two types of shaft screw conveyor and shaft less screw conveyor, on the outside it is divided into U screw conveyor and tubular screw conveyor. The shaft spiral conveyor is suitable for non sticky dry powder materials and small granular materials. For example, cement, fly ash, lime, grain, etc., and the shaft less screw conveyor is suitable for conveyors from viscous and easily wound materials. (for example: the screw conveyor of sludge, biomass, garbage, etc.) the working principle of the screw conveyor is that the rotating spiral blade will transport the material through the screw conveyor, so that the force of the material not rotating with the screw conveyor blades is the frictional resistance of the material's own weight and the screw conveyor's shell to the material. The surface of the spiral blade welded on the rotating shaft of the screw conveyer has the shape of the solid surface, the belt face type and the blade face type according to the different conveying materials. The screw shaft of the screw conveyor has thrust bearings at the end of the material movement direction to react with the axial force of the material to the helix, and the middle hanging bearing should be added when the length of the screw is longer.
The working principle of screw conveyor is:
When the helix shaft rotates, the gravity of the material and the frictional force generated by the wall of the tank cause the material to move forward along the bottom of the conveyor only under the push of the blade, which is as if the rotating nut can not be rotated along the rotating screw. The movement of material in the middle bearing depends on the thrust of the advancing material. Therefore, the transportation of materials in the conveyor is entirely a slip motion. In order to make the screw shaft in a more favorable tension state, the driving device and the discharge port are usually placed at the same end of the conveyor, and the feeding port is placed near the tail of the other end. The rotating spiral blades carry the material forward, so that the force that the material does not rotate with the screw conveyor blades is the frictional resistance of the material's own weight and the screw conveyor's shell to the material. According to the different conveying materials, the surface shape of the blade has solid shape, belt type and blade face type. The screw shaft of the screw conveyor has thrust bearings at the end of the material movement direction to react with the axial force of the material to the helix, and the middle hanging bearing should be added when the length of the screw is longer.
