Technical Field

[0001] The utility model relates to the technical field of slag removal devices, in particular to a slag removal device for a boiler in a thermal power plant. Background Art

[0002] Boiler refers to a medium-sized or large boiler in a power plant that provides a specified amount and quality of steam to the steam turbine. It is one of the main thermal equipment in a thermal power plant. After working for a long time, the boiler in a thermal power plant needs to use a slag removal device to clean the coal ash on the inner wall. However, the current slag removal device has a high cleaning cost and requires a lot of investment.

[0003] In order to reduce the cost of slag removal, after searching, the utility model with patent publication number CN219640283U discloses a slag removal device for a thermal power plant boiler. By setting a first ear sleeve, a ring seat, a driving motor, a transmission screw, a circular plate, an I-shaped slide rail, a sliding sleeve, a slag removal knife, a spiral sleeve, a connecting seat, a movable plate, a first L-shaped rod, a threaded sleeve and a second L-shaped rod and other structures, the spiral sleeve is rotated in cooperation with the connecting seat and the movable plate to make the sliding sleeves on both sides move to both sides along the I-shaped slide rail, thereby adjusting the slag removal knife to fit the inner wall of the boiler. Subsequently, the slag removal knife can be driven by the driving motor to scrape the coal slag on the inner wall of the boiler from bottom to top. Although it is convenient to clean the coal ash on the inside of the boiler, it is necessary to disassemble the furnace mesh first during cleaning and then install the furnace mesh after cleaning. The disassembly and installation are likely to waste a certain amount of time, which is easy to prolong the cleaning time and is likely to affect the subsequent slag removal efficiency of the thermal power plant boiler.
