It is composed of a driving device, a closed tank box and a spiral, and the coal in the tank box is output by rotating the screw.
The characteristics of screw conveyor are: simple structure, small cross-sectional size, good sealing, reliable work, low manufacturing cost, convenient intermediate loading and unloading, and the conveying direction can be reversed, and it can also be transported in the opposite direction at the same time. During the conveying process, the material can also be stirred, mixed, heated and cooled. The material flow can be adjusted by means of loading and unloading gates. However, it is not suitable to transport perishable, viscous, easy to agglomerate and large materials. During the conveying process, the material is easy to break, and the spiral and trough are easy to wear. The unit power is large. In use, it is necessary to maintain the tightness of the material chute and have an appropriate gap between the spiral and the material chute.
Vertical screw conveyor is suitable for short distance vertical conveying. The screw of the bendable screw conveyor is composed of a flexible shaft and synthetic rubber blades, which are easy to bend, and can be arbitrarily arranged according to site or process requirements for space transportation. Screw conveyor blades have spot pull type and whole pull loss, the current pull type can be made into any thickness and specification size, the whole pull type is not suitable for making non-standard spiral.
From the perspective of the displacement direction of conveying materials, Hongtai screw conveyor is divided into two types of horizontal screw conveyor and vertical screw conveyor, mainly used for horizontal conveying and vertical lifting of various powdery, granular and small pieces of loose materials, the screw conveyor is not suitable for transporting perishable, viscous, easy to agglomerate or high temperature, pressure-sensitive, corrosive special materials.
The screw conveyor is generally composed of three parts: conveyor body, inlet and outlet and driving device; The spiral blade of the screw conveyor has three forms: solid spiral surface, belt spiral surface and blade spiral surface, of which the blade spiral surface is relatively less used, mainly used to transport large viscosity and compressible materials, this screw suspension type, in the process of completing the conveying operation, at the same time has and complete the mixing and mixing of the material and other functions.
Compared with other conveying equipment, screw conveyor has the advantages of small cross-sectional size, good sealing performance, stable and reliable operation, intermediate multi-point loading and unloading, safe operation, and simple maintenance.
