[0034] A protective shell 5 is installed at the center of the bottom end of the sorting box 2. The protective shell 5 is sleeved on the surface of the rotating shaft 4. The bottom end of the protective shell 5 does not contact the sorting box 2. When the sorting box 2 rotates, the protective shell 5 will not rotate therewith.

[0035] The transmission structure 6 is located inside the protective shell 5, and the transmission structure 6 includes a driven bevel gear 17, which is fixedly sleeved on the surface of the rotating shaft 4. One end of the transmission rod 7 is rotatably connected to the inside of the protective shell 5, and the driving bevel gear 18 is fixedly installed at one end of the transmission rod 7. The driving bevel gear 18 is meshed and connected with the driven bevel gear 17. A water wheel 8 is installed at the other end of the transmission rod 7. A feed pipe 20 is installed above the sorting box 2, and the feed pipe 20 is connected to an external device for injecting slurry into the sorting box 2.

[0036] The feed pipe 20 is located directly above the water wheel 8. The slurry in the feed pipe 20 flows downward, driving the water wheel 8 to rotate. The water wheel 8 drives the transmission rod 7 to rotate. The rotating rod 7 drives the active bevel gear 18 to rotate, and the meshing driven bevel gear 17 drives the rotating shaft 4 to rotate, thereby driving the sorting box 2 to rotate. The distribution pipe 10 is fixedly installed on the outer wall of the sorting box 2. There are four distribution pipes 10 evenly arranged. The distribution pipe 10 rotates with the sorting box 2, so that the distribution pipe 10 can evenly distribute the slurry to the cross partition plates 3 inside the distribution box 1, wherein the highest point of the water wheel 8 is higher than the pipe mouth of the distribution pipe 10 in the sorting box 2.

[0037] The wall scraping stirring structure 9 is connected to the surface of the rotating shaft 4. The wall scraping stirring structure 9 includes a cross bar 11. Two cross bars 11 are fixedly installed on the symmetrical two end surfaces of the rotating shaft 4. A scraper 12 is installed at the other end of the cross bar 11. The scraper 12 fits the inner wall of the sorting box 2. When the slurry flows into the sorting box 2 from the feed pipe 20, the slurry will splash onto the inner wall of the sorting box 2. When the rotating shaft 4 rotates, it drives the cross bar 11 and the scraper 12 to rotate, and the slurry on the inner wall of the sorting box 2 can be scraped off.

[0038] Two connecting frames 13 are fixedly mounted on the symmetrical end surfaces of the rotating shaft 4, the connecting frame 13 and the cross bar 11 are spaced 45 degrees apart, a stirring rod 14 is installed inside the connecting frame 13, and multiple groups of stirring rods 14 are staggered inside the connecting frame 13, which can break up and stir the slurry scraped by the scraper 12 to ensure the uniformity of the powder, a connecting block 15 is fixedly mounted on one end of the connecting frame 13, and a cross 16 is installed on the other end of the connecting block 15, one end of the cross 16 is slidably connected to the inside of the connecting block 15, and a limiting groove is installed inside the connecting block 15. When the connecting frame 13 rotates, the cross 16 slides outward under inertia, and the limiting groove prevents the cross 16 from detaching from the connecting block 15. The height of the lower end of the cross 16 is below the height of the upper end of the water wheel 8, which can stir the slurry and improve the uniformity of the material distribution.

[0039] A discharge pipe 19 is installed at the lower end of the branch box 1. There are four discharge pipes 19. The four discharge pipes 19 correspond to the four parts divided by the cross partition plate 3 inside the branch box 1. The branch box 1 receives the slurry. Valves are installed on the discharge pipe 19 and the distribution pipe 10 to facilitate the control of unloading.

[0040] Embodiment 2

[0041] Described on the basis of Example 1, the feed pipe 20 is connected to an external device and is used to inject slurry into the sorting box 2. The slurry in the feed pipe 20 flows downward, driving the water wheel 8 to rotate, the water wheel 8 drives the transmission rod 7 to rotate, the rotating rod 7 drives the active bevel gear 18 to rotate, and the meshing driven bevel gear 17 drives the rotating shaft 4 to rotate, thereby driving the sorting box 2 to rotate. The distribution pipe 10 rotates with the sorting box 2, so that the distribution pipe 10 can evenly distribute the slurry to the cross partition plates 3 inside the distribution box 1. When the rotating shaft 4 rotates, it drives the cross bar 11 and the scraper 12 to rotate, and the slurry on the inner wall of the sorting box 2 can be scraped off. The connection frame 13 is driven to rotate by the rotation of the rotating shaft 4, and the cross 16 slides outward under inertia, which can stir the slurry and improve the uniformity of the slurry distribution. The slurry is evenly distributed between the cross partition plates 3, and the discharge pipe 19 can facilitate unloading.
