Technical characteristics The closed box and spiral parts of the driving device are rotated through a spiral to transfer the coal in the tank.
The characteristics are: simple structure, small cross section size, good sealing, reliable work, low manufacturing cost, convenient for intermediate loading and unloading, converse transportation direction and two directions at the same time. During transportation, materials can also be stirred, mixed, heated and cooled. The flow of material can be adjusted by loading and unloading gate. But it is not suitable to transport easily deteriorated, sticky, caking and chunky materials. During transportation, the material is easy to break, and the spiral and groove are easy to wear. The unit power is large. The sealing of the grooves and the proper clearance between the spiral and the material grooves should be kept in use.
Vertical Screw Conveyor is suitable for short distance vertical transportation. The screw of the flexible screw conveyer is composed of flexible shaft and synthetic rubber blade. It is easy to bend. It can be transported in space according to the requirements of field or process. The blade of the screw conveyor is pulled and pulled out. The drawing type can be made into any thickness and size. From the angle of conveying material displacement direction, the screw conveyer is divided into two types, horizontal screw conveyor and vertical screw conveyor. It is mainly used for horizontal and vertical lifting of various loose materials such as powdery, granular and small pieces. The screw conveyer is not suitable for metamorphism, large stickiness and easy caking. Or special materials with high temperature, pressure and corrosiveness. The screw conveyer is usually composed of three main parts: the conveyor body, the inlet and outlet and the driving device. The spiral blade of the screw conveyer has three forms of the solid spiral surface, the belt spiral surface and the blade spiral surface. Among them, the blade type spiral surface is used relatively less, which is mainly used to transport the large viscosity and compressible materials, such a screw. In the process of conveying, it has the functions of mixing and mixing materials. Compared with other conveying equipment, screw conveyor has the advantages of small section size, good sealing performance, stable and reliable operation, multi point loading and unloading, safe operation and easy maintenance.
