By the driving device closed trough box and spiral composition borrow the spiral to rotate the tank in the coal output.
The characteristics of screw conveyor are: simple structure, small cross-section size, good sealing, reliable work, low manufacturing cost, convenient for intermediate loading and unloading, conveying direction can be reversed, also can be transported in two directions at the same time. During the conveying process, the materials can be stirred, mixed, heated and cooled. The material flow can be adjusted by the loading gate. But it is not suitable to transport perishable, viscous large, easily caking and bulk materials. In the process of conveying materials easily broken, spiral and material trough easy to wear. Unit power is larger. In use to maintain the sealing of the material groove and the spiral and material slots between the appropriate clearance.
Vertical screw conveyor is suitable for short distance vertical conveying. The helical screw conveyor is composed of flexible shaft and synthetic rubber blades, and is easy to bend, and can be arbitrarily arranged according to the site or process requirements. Screw conveyor blades are pulling and pulling loss, now pull can be made of arbitrary thickness and size, the whole pull type should not be made non-standard spiral.
The follow screw conveyor is divided into two types: horizontal screw conveyor and vertical screw conveyor from the angle of displacement direction of conveying material. Mainly used for a variety of powdery, granular and small pieces of loose materials such as horizontal transportation and vertical lifting, the screw conveyor is not suitable for conveying perishable, viscous, easy to caking or high-temperature, afraid of pressure, Special materials with large corrosive property.
Screw conveyor is generally composed of three parts: conveyor body, inlet and outlet and driving device. Spiral Conveyor Spiral blades have solid helical surface, belt spiral surface and blade helix surface three kinds of forms, among them, the blade type Helix surface application is relatively few, mainly used for conveying the viscosity of large and compressible materials, this kind of screw suspension, In the completion of the delivery process, at the same time have and complete the material mixing, mixing and other functions.
Compared with other conveying equipment, screw conveyor has the advantages of small cross-section size, good sealing performance, stable and reliable operation, high intermediate loading and unloading, safe operation and easy maintenance.
