After the mixing operation is completed, discharge the materials through the discharge pipe, and then start the hydraulic cylinder 14 to drive the arc plate 15 to move downward. When the arc plate 15 moves downward, it drives the fixed ring 16 and the rotating ring 17 to move downward synchronously, and the raw materials sticking to the inner wall of the side of the kettle body 1 are scraped off by the rotating ring 17. When the rotating ring 17 drops to a suitable position, the inclined scraper 21 fits with the inclined inner wall of the kettle body 1.
