Screw conveyor equipment is a kind of use of motor driven spiral rotation, push the material to achieve the purpose of conveying machinery.
Working principle:
When the spiral shaft rotates, due to the gravity of the material and the friction generated by the tank wall, the material can only move forward along the trough of the conveyor under the push of the blade, as if the nut can not rotate along the rotating screw for translation movement. The main driving force of materials is the upward and forward force of the helical blade along the tangential direction of the blade when it is rotating axially.
Structural features:
1. The spiral blade of the tubular screw conveyor has two kinds of rotation directions: left and right.
2. Screw conveyor is composed of three parts: screw machine body, inlet and outlet and driving device.
3. The screw blade of the screw conveyor has three kinds of solid screw surface type, belt screw surface type and blade screw surface type. Solid screw surface known as s method, the screw pitch GX type for blade diameter 0.8 times, LS type screw conveyor is suitable for conveying powder and granular materials.
