[0023] Through the vent pipe 207, which is supplied with air by an external high-pressure air pump, high-pressure gas can be ejected from the nozzle 208, so that the surface of the furnace body 1 can be flushed to prevent slagging. Through the reduction motor 201, the matching gear 202 can be driven to rotate, so that the rotating frame 203 can rotate on the rotating sleeve 204 and the support frame 205 which are bearings, so that the rotating frame 203 can drive the scraper plate 206 to rotate together, and then the scraper plate 206 can regularly scrape and clean the surface of the furnace body 1.
