Description

Technical Field

[0001] The utility model relates to the technical field of metal melting equipment, and particularly relates to a cleaning device. Background Art

[0002] During the melting process of an electric arc furnace, pollutants such as particulate matter, flaky scale deposits, and floating ash will form on the inner wall of the furnace chamber; in order to avoid affecting the quality of the ingot in the next melting, it is necessary to clean in time to prevent huge losses.

[0003] The traditional cleaning method is that after the melting is completed, workers enter the furnace chamber manually, and use tools such as stainless steel scrapers and putty knives to remove particulate matter and flaky scale deposits, and finally use a rag to wipe the floating ash on the surface clean. This cleaning method has high labor intensity for workers, long operation time, incomplete cleaning, low work efficiency. Most importantly, the metal dust and sparks generated during cleaning will pose risks of major diseases such as respiratory diseases to the cleaning workers in the relatively enclosed furnace chamber, as well as other unsafe accidents.

[0004] Existing furnace chambers adopt an automatic device to replace manual cleaning. For example, the Chinese invention patent with the publication number CN107883759A discloses a furnace chamber cleaning device for a vacuum consumable arc furnace. The central position of the cleaning turntable is connected to the rotating shaft of the motor. An inner ring is provided inside the cleaning turntable. A plurality of sliding grooves are evenly provided on the side wall of the cleaning turntable. A cleaning head is installed in each sliding groove. A brush is provided on the outer side surface of the cleaning head. The inner side surface of the cleaning head is connected to the inner ring through a spring; a plurality of dust suction holes are evenly provided on the side wall of the cleaning turntable and between adjacent two sliding grooves. An arc-shaped dust collection cover is provided on the top of the cleaning turntable. A connecting head is provided on the top of the dust collection cover. A first dust suction pipe is provided inside the connecting head. One end of the first dust suction pipe is communicated with the dust collection cover. The other end of the first dust suction pipe extends out of the connecting head and is connected to a dust collector through a second dust suction pipe. A valve is provided on the first dust suction pipe near the second dust suction pipe. A compressed air inlet pipe is provided on the first dust suction pipe between the valve and the connecting head. The existing automatic cleaning device has only one cleaning head, and the cleaning efficiency is low. Summary of the Utility Model
