[0034] In a specific implementation manner, an anti-corrosion layer is provided on the surface of the cone box 110. By providing the anti-corrosion layer, the anti-corrosion capability is improved and the service life is extended.

[0035] See also Figure 1 , 2 , 4 and 5, the stirring cleaning assembly 200 includes a fixed plate 210, a central control shaft 220, a shaft rod 230, a driving motor 250, a stirring rod 260 and a scraper 270, the fixed plate 210 is arranged at the top of the cone box 110, the central control shaft 220 rotates and passes through the fixed plate 210, the shaft rod 230 rotates and passes through the central control shaft 220, two driving motors 250 are provided and fixedly connected to the fixed plate 210, the two driving motors 250 are respectively connected to the central control shaft 220 and the shaft rod 230, the surfaces of the central control shaft 220 and the shaft rod 230 are both provided with stirring rods 260, and the scraper 270 is arranged at the end of the stirring rod 260 and contacts the inner wall of the cone box 110.

[0036] In this embodiment, the driving motor 250 is connected to the rotating shaft rod 230 and the central control rotating shaft 220 through the gear set 240. The gear set 240 includes a driving gear 241 and a driven gear 242. The driving gear 241 is fixedly connected to the output end of the gear set 240.
