Screw conveyor commonly known as the dragon, screw conveyor using rotating spiral blade to push the material goes on conveying. The force that the material does not rotate with the screw conveyor blade is the weight of the material itself and the frictional resistance of the screw conveyor housing to the material. Screw conveyor on the rotating shaft of the spiral wound, the blade surface type according to the different materials are solid surface, belt type, leaf surface type and other types. The screw shaft of the screw conveyor has a thrust bearing at the end of the direction of movement of the material to the axial reaction force of the screw with the material. When the length of the screw is longer, the bearing should be suspended. Is a mineral, feed, grain and oil, the construction industry in a wider range of transportation equipment, made of steel, for the transmission of high temperature powder or solid particles and other chemical, building materials.
The classification of screw conveyor
Screw conveyor from the direction of transport material division, divided into horizontal screw conveyor and vertical screw conveyor two types.
Screw conveyor according to the characteristics of the transport material requirements and structure can be divided into horizontal screw conveyor, vertical screw conveyor, flexible screw conveyor, spiral (roller conveyor) conveyor.
(1) Vertical screw conveyor
The speed of the spiral of the vertical screw conveyor is higher than that of the conventional screw conveyor, and the added material produces a frictional force between the shell and the friction force, which prevents the material from rotating with the spiral blade and overcomes the material drop of gravity, thus achieving the vertical transport of materials. The machine transport volume is small, the transmission height is small, the speed is higher, and the energy consumption is big. Particularly suitable for conveying fluidized powdery granular material, mainly used to enhance the material, lifting height is generally not greater than 8 meters.
(2) Horizontal screw conveyor When the material is added to the fixed tank, due to the gravity of the material and the friction between the role of the machine, the material deposited in the lower part of the machine does not rotate with the spiral body, but only in the rotation of the spiral blade to move forward, as the non-rotating nut along the rotation of the screw as a translational movement, to achieve the purpose of conveying materials.
(3) Spiral tube (roller conveyor) Conveyor
The spiral tube is a continuous spiral blade in a cylindrical housing that rotates together with the spiral blade. The addition of the material due to the role of centrifugal force and friction together with the shell rotation and be promoted, under the action of the gravity of the material and then along the spiral surface, so that the material with the spiral tube rotation together to achieve the material forward movement, as does not rotate of the screw along the rotation of the nut as a translational movement, to achieve the purpose of conveying materials.
