Description

Boiler ash cleaning device of power plant Technical Field The utility model relates to the technical field of ash cleaning equipment, in particular to a boiler ash cleaning device of a power plant boiler. Background During the operation of the power plant boiler, the furnace ash can be gradually accumulated on the inner wall of the boiler body. The accumulation of the furnace dust not only can influence the heat conduction efficiency of the boiler, so that energy waste is caused, the overall operation efficiency of the boiler is reduced, but also the furnace dust accumulated for a long time can corrode the inner wall of the boiler, the service life of the boiler is shortened, and even potential safety hazards are caused. The existing equipment has the following defects that at present, the cleaning work of boiler ash mostly depends on manual operation, and the mode has a plurality of defects. On one hand, manual cleaning has high labor intensity, severe working environment, high temperature, dust and other conditions form a threat to the health of operators, and on the other hand, the manual cleaning is difficult to ensure the comprehensive and thorough cleaning of the inner wall of the boiler, the cleaning effect is unstable, the cleaning efficiency is low, and the high-efficiency operation requirement of the power plant boiler cannot be met. The application provides a boiler ash cleaning device for a power plant boiler, which solves the problems. Disclosure of utility model The utility model aims to provide a boiler ash cleaning device for a power plant, which is used for solving the problems that the labor intensity of manual cleaning is high, the working environment is bad, the conditions such as high temperature and dust are threatening to the health of operators, on the other hand, the manual cleaning is difficult to ensure the comprehensive and thorough cleaning of the inner wall of the boiler, the cleaning effect is unstable, the cleaning efficiency is low, and the high-efficiency operation requirement of the power plant boiler cannot be met. In order to achieve the purpose, the utility model provides the following technical scheme that the ash cleaning device for the power plant boiler comprises an installation pipe inserted into the boiler body, and further comprises: The travelling mechanism is arranged on the outer circular end surface of the mounting tube at equal angles and is abutted against the inner wall of the boiler body, and is used for driving the mounting tube to travel in the boiler body; the adjusting mechanism is arranged on the mounting tube and connected with the travelling mechanism and is used for adjusting the distance between the travelling mechanism and the mounting tube; The cleaning mechanism is arranged on one side of the installation tube and is in butt joint with the inner wall of the boiler body and used for cleaning the inner wall of the boiler body. The cleaning mechanism comprises a second motor arranged in the mounting tube, a rotating shaft arranged at the power output end of the second motor, a rotating disc arranged on one side of the rotating shaft away from the mounting tube, and cleaning pieces arranged on the rotating disc at equal angles, wherein the mounting tube is provided with a mounting groove for placing the second motor, and the rotating disc is provided with a mounting ring for mounting the cleaning pieces. The cleaning piece comprises a telescopic rod penetrating through the mounting ring and a scraper arranged on one side of the telescopic rod away from the mounting ring, and a placing groove for the telescopic rod to move is formed in the position of the rotary disc corresponding to the telescopic rod.
