Description

Technical Field

[0001] The utility model relates to the technical field of dust cleaning devices, in particular to a rapid dust cleaning device for a waste heat boiler of an electric furnace. Background Art

[0002] The utility model discloses a rapid ash cleaning device for an electric furnace waste heat boiler, which is a device specially used for removing ash accumulation in a boiler so as to improve the thermal efficiency of the boiler and ensure safe and stable operation.

[0003] After searching, a Chinese utility model patent disclosed a quick ash cleaning device for an electric furnace waste heat boiler with a publication number of CN215411927U, comprising a bottom plate, a foot pad fixedly installed at the lower end of the bottom plate, a boiler body fixedly installed at the upper end of the bottom plate, a furnace door movably installed at the left end of the boiler body through a hinge, a side plate fixedly installed at the left end of the upper end of the bottom plate, a left support plate fixedly installed at the middle of the left end of the side plate, a dust box fixedly installed at the upper end of the left support plate, a dust collector fixedly installed at the upper end of the dust box, a right support plate fixedly installed at the middle of the right end of the side plate, a first electric push rod fixedly installed at the upper end of the right support plate, and a first push rod movably installed at the transmission end of the first electric push rod. The quick ash cleaning device for an electric furnace waste heat boiler has the function of collecting ash, avoids the inconvenience caused by human entry into the boiler for cleaning, effectively improves the ash cleaning efficiency, makes the ash cleaning process more convenient, and further improves the simplicity of ash cleaning.

[0004] However, the device often lacks the function of changing the scraper plate structure. When in use, the scraper plate usually corresponds to the rectangular structure of the inner wall of the furnace body when scraping, but the structure of the inner wall of the furnace body may be cylindrical. The relatively fixed scraper plate structure cannot completely scrape the cylindrical inner wall of the furnace body, and the scraper plate cannot scrape the dust in the dead corners of the inner wall of the furnace body, resulting in dust in some dead corners that cannot be scraped out due to the obstruction of the scraper plate itself. The dust on the inner wall of the furnace body cannot be completely scraped out, and an additional secondary operation or manual dust removal is required, which reduces the efficiency of cleaning. The scraper plate structure cannot be changed according to actual conditions, and the scraper plate has low adaptability and flexibility. Not only that, the The device also lacks the function of dissipating the heat inside the furnace body. When in use, the furnace body generates heat during operation and the temperature is relatively high. After the furnace body stops operating, a large amount of heat is still accumulated inside the furnace body. In order to avoid damage to the scraper plate caused by working inside the high-temperature furnace body, the furnace door can only be opened to allow the furnace body to naturally dissipate the heat and reduce the heat. The furnace body needs to dissipate the heat naturally before each ash cleaning. As a result, when the furnace body is not in operation, the inside of the furnace body cannot be cleaned in time, and a long time is required to wait for natural cooling. Ash accumulation that is not removed in time may cause local overheating, increasing the safety hazard of the boiler. Ash accumulation that is not removed in time may affect the heat transfer efficiency of the boiler heating surface, thereby affecting the power generation. Utility Model Content
