[0021] The upper end of the hollow inner shaft 3 is connected with the liquid inlet pipe 32 through a rotary joint 31, and the lower end of the hollow inner shaft 3 is fixed with a distributing disc 33, which is provided with a plurality of liquid distributing holes 331. Further, the liquid distributing holes 331 are arranged on the peripheral wall of the distributing disc 33, so that the material can be thrown out by centrifugal force when the distributing disc 33 rotates. At this time, the liquid material is introduced into the distributing disc 33 from the liquid inlet pipe 32 through the hollow inner shaft 3. When the material is arranged, the hollow inner shaft 3 rotates to drive the distributing disc 33 to rotate, and the liquid medicine is thrown out by the liquid distributing holes 331 of the distributing disc 33 through centrifugal force, so as to be uniformly mixed with other materials in the tank body 1, thereby improving the mixing effect. When the tank body 1 is cleaned, cleaning liquid can be introduced into the hollow inner shaft 3, and at this time, the cleaning liquid is thrown out through the liquid distributing holes 331 of the distributing disc 33, so as to increase the contact area with the tank body 1 and improve the cleaning efficiency.

One end of the elastic piece 464 is fixed to the scraper 463, and the other end is fixed to a convex rib on the horizontal rod 461. At this time, the elastic piece 464 can be a spring. When the vertical rod 45 rotates with the mounting disc 41, the scraper 463 moves in the circumferential direction along the inner wall of the tank body 1 to scrape off the material adhered to the inner wall of the tank body 1. Under the action of the elastic piece 464, the scraper 463 has a force to move towards the inner wall of the tank body 1, so as to press the scraper 463 against the inner wall of the tank body 1, thereby improving the scraping effect.
