[0002] A boiler is an energy conversion device. Existing boilers typically use coal as fuel, which produces ash after combustion. Coal-fired boilers require regular cleaning of the ash in the boiler to ensure energy conversion efficiency and reduce energy loss.

[0003] For example, a ash cleaning device for coal-fired boiler maintenance disclosed in the utility model with authorization announcement number CN221301346U relates to the technical field of ash cleaning equipment, including a base and a boiler body fixedly installed in the middle of the top surface of the base, a driving motor is fixedly installed on the outer periphery of the top surface of the base, a first winding rod is installed in the lower end inner cavity of the boiler body, and a second winding rod is installed in the upper end inner cavity of the boiler body, and a scraper ring is slidably installed on the inner wall of the inner cavity of the boiler body, and the scraper ring is connected to the first winding rod and the second winding rod by a pair of connecting wires respectively. When the output end of the driving motor rotates forward, the first winding rod can be driven to rotate forward. At the same time, under the transmission action of the transmission belt, the second winding rod can be driven to rotate forward together. In this process, the first winding rod can reel in the connecting wire, and the second winding rod will release the connecting wire. The scraper ring can be driven to slide along the inner wall of the boiler chamber through the connecting wire, thereby achieving the effect of scraping and cleaning. However, during the application of this technical solution, when the dust is collected and filtered by the dust collecting component and the dust is sucked out of the boiler, dust is likely to clog the filter screen inside the dust collecting component, affecting the normal operation of the cleaning equipment. There is a technical problem that the ash residue that is easy to clog the filter screen of the dust collecting component cannot be brushed off to ensure the normal filtering and dust collection of the dust collecting component and the normal operation of the cleaning equipment.
