In the layout of thermal power plant, the layout of coal conveying system has an important influence on it. In the general layout of most power plants. The coal storage yard keeps a certain distance from the coal bunker frame, mainly because the inclination angle of coal conveying belt to the main plant house should be controlled within 16° ~ 18°, which limits the general layout and makes the plant area larger. In recent years, the tubular belt has been applied in the coal conveying system of thermal power plant. The pipe belt technology has increased the elevation angle of the coal conveying belt to 46° ~ 48°, reducing the distance between the coal yard and the main plant, thus making the layout of the coal yard flexible and reducing the factory area. With the development and application of technology, various belt conveyors are widely used in foreign thermal power plants, corrugated sidewall belt conveyor is one of them.
Brief introduce of
corrugated sidewall belt conveyor
Sidewall belt conveyor is a kind of material conveyed equipment with advanted technology and flexible layout, which mainly consists of conveyor belt, driving pulley, impact idler, return idler, carrying idler, guide pulley and tension idler, etc. Conveyor belt consists of base belt, corrugated sidewall and cross slab. Base belt is made of upper cover rubber, lower cover rubber, core and Transverse rigidity layer. The belt width usually is 4 times higher than corrugated sidewall, the transverse distance generally is the 2 times larger than the maximum size of material.
The features of sidewall belt conveyor
1) Large conveying capacity. In current, the conveying capacity of sidewall belt conveyor can achieve 6000t/h.
2) Large inclined angle, and high lifting height. Because different layout form of cross slab and unique structure, the sidewall belt conveyor can convey material under the inclination angle of 0°～ 90°, and the 500m weitical lifting heigth can be achieved, and the 180° torsion angle can be realized during the process of vertical lifting.
3) Flexible layout, small floor area. Because the
corrugated sidewall belt conveyor can transfer material under the inclination angle range of 0°～ 90°, at the same time, the 180° torsion angle can be realized during the process of vertical lifting. Therefore, the material storage and the position of the end point that material transportation will be flexible. It can layout according to the specific landform and clients requirements, it greatly improve the space utilization and reduce the floor area.
Sidewall belt conveyor is widely used for electric powder, mining and other industries. As a kind of mature and reliable coal-burning conveying machinery, the sidewall belt conveyor has been successfully applied in foreign coal-fired power plants, especially in the vertical lifting of large capacity sidewall belt conveyor.
