Multistage automatic deviation rectifying device for coal conveying belt of thermal power plant

Abstract

The invention discloses a multistage automatic deviation rectifying device for a coal conveying belt of a thermal power plant. The device comprises a coal scraping deviation rectifying mechanism, a turnover deviation rectifying mechanism and a forced deviation rectifying mechanism which are sequentially arranged in the running direction of the belt. The multistage automatic deviation rectifying device for the coal conveying belt of the thermal power plant is a passive belt automatic deviation rectifying system, a large amount of cost is saved, and the problems that a carrier roller support isunstable due to the fact that deviation is adjusted through a traditional rotating carrier roller, and abrasion is increased due to the fact that the carrier roller makes contact with the belt all thetime are solved. Meanwhile, the complex situation that a motor and a hydraulic cylinder serve as power is reduced, the problem that the support is unstable is solved, the deviation rectifying carrierroller does not make contact with the belt at ordinary times, and abrasion is relieved. The problem that the belt deviates due to the fact that the coal falling point position is not correct is solved from the source through a passive coal scraping plate. The deviation rectifying force is increased through a forced deviation rectifying wheel, and the danger caused by falling of the belt is reduced.

Description

technical field [0001] The invention relates to the technical field of belt deviation correction, in particular to a multi-stage automatic deviation correction device for a coal conveying belt in a thermal power plant. Background technique [0002] The belt conveyor is a main continuous transportation equipment, which realizes continuous transportation through the friction transmission belt. The belt conveyor has the advantages of large conveying capacity, various conveying materials, adaptable to various conveying lines, flexible conveying distance, smooth and reliable operation, less power loss, high working efficiency, long service life, convenient installation, free loading and unloading, etc. , Widely used in material transmission systems in coal, electric power, building materials, chemicals, machinery, light industry and other industries. [0003] Therefore, the smooth and reliable operation of the belt is a very critical issue. However, during the operation of the ...

AI Technical Summary

Problems solved by technology

At present, the application effect of the deviation correction equipment for the coal conveying belt is not very good, and the equipment is expensive but the ideal deviation correction effect cannot be obtained. Therefore, the realization of the deviation correction control of the coal conveying belt conveyor is of great significance to the safe and efficient production of thermal power plants
