Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-5A mixer for polishing alumina production shown in the figure includes a mixing drum 1, a drum cover 2 is provided at the top end of the mixing drum 1, a mixing assembly is provided at the bottom end of the drum cover 2, a rotating groove is provided at the bottom end of the drum cover 2, an annular plate 6 is rotatably installed in the rotating groove, a rotating assembly is provided on the inner wall of the circumference of the annular plate 6, a lifting hole is provided at the bottom end of the annular plate 6, an avoidance hole matched with the lifting hole is provided at the top end of the drum cover 2, a rectangular lifting plate 10 is slidably installed in the lifting hole, a lifting assembly is provided on one side of the rectangular lifting plate 10, a cleaning assembly is provided on the other side of the rectangular lifting plate 10, a limiting assembly matched with the rectangular lifting plate 10 is provided on the inner wall of the bottom end of the mixing drum 1, and a heating wire 19 is provided in the mixing drum 1.

[0024] With the above structure, during normal operation, the rectangular lifting plate 10 is located outside the top of the drum cover 2. When cleaning is needed after use, first add clean water into the mixing drum 1, and then drive the rectangular lifting plate 10 and the cleaning assembly downward to a suitable position through the lifting assembly, and limit the rectangular lifting plate 10 under the action of the limiting assembly, and then drive the annular plate 6 and the cleaning assembly to rotate through the rotating assembly to clean the inner wall of the surrounding side of the mixing drum 1, which effectively improves the cleaning effect.

[0025] like Figure 4 As shown, the stirring assembly includes a stirring shaft 3, the top end of the stirring shaft 3 is rotatably connected to the bottom end of the drum cover 2, a stirring motor 4 is fixedly installed on the top end of the drum cover 2, the output shaft of the stirring motor 4 is connected to the top end of the stirring shaft 3, and a plurality of stirring rods 5 are arranged on the peripheral outer wall of the stirring shaft 3. The advantage of such an arrangement is that the stirring function of the slurry in the mixing drum 1 can be realized through the arrangement of the stirring shaft 3 and the stirring rods 5.

[0026] Specifically, when the slurry needs to be stirred, the stirring motor 4 is started to drive the stirring shaft 3 to rotate, and then drive the multiple stirring rods 5 to rotate synchronously, thereby realizing the stirring function of the slurry and improving the stirring effect.

[0027] like Figure 5 As shown, the rotating assembly includes an annular inner rack 7 and a rotating motor 8. The annular inner rack 7 is fixedly arranged on the inner wall of the circumference of the annular plate 6. The rotating motor 8 is fixedly installed on the top of the cylinder cover 2. The output shaft of the rotating motor 8 extends into the rotating groove and is fixedly sleeved with a rotating gear 9. The rotating gear 9 is meshed and installed with the annular inner rack 7. The advantage of such an arrangement is that, through the arrangement of the annular inner rack 7 and the rotating motor 8, the rotating gear 9 can be driven by the rotating motor 8 to rotate synchronously, thereby driving the annular plate 6 to realize the rotation function through the meshing action of the rotating gear 9 and the annular inner rack 7.

[0028] Specifically, when the annular plate 6 needs to be driven to rotate, the rotating motor 8 is started to drive the rotating gear 9 to rotate, and then the annular plate 6 is driven to rotate under the meshing action of the rotating gear 9 and the annular inner rack 7, thereby driving the rectangular lifting plate 10 and the cleaning component to achieve synchronous rotation.

[0029] like Figure 5 As shown, the lifting assembly includes a lifting motor 14 and a lifting rack 16. A protective box 13 is provided at the bottom end of the barrel cover 2. The lifting motor 14 is fixedly installed on the inner wall of the side of the protective box 13. A lifting gear 15 is fixedly sleeved on the output shaft of the lifting motor 14. The lifting rack 16 is fixedly installed on the side of the rectangular lifting plate 10. The lifting gear 15 is meshed with the lifting rack 16. The advantage of such an arrangement is that, through the arrangement of the lifting motor 14, the lifting gear 15 and the lifting rack 16, the lifting motor 14 can drive the rectangular lifting plate 10 to perform lifting and lowering movements, which is convenient for storing the cleaning assembly.

[0030] Specifically, when the mixing drum 1 is stirring, the lifting motor 14 drives the lifting gear 15 to rotate, thereby driving the rectangular lifting plate 10 to move upward through the action of the lifting rack 16, thereby driving the rectangular lifting plate 10 and the cleaning component to move outside the mixing drum 1 to prevent contamination of the cleaning component during stirring.

[0031] like Figure 5 As shown, the cleaning component includes a scraper 11 and a cleaning brush 12. The scraper 11 and the cleaning brush 12 are both arranged on the other side of the rectangular lifting plate 10. The scraper 11 and the cleaning brush 12 are both adapted to the mixing drum 1. The advantage of such an arrangement is that the inner wall of the circumferential side of the mixing drum 1 can be cleaned by the arrangement of the scraper 11 and the cleaning brush 12.

[0032] Specifically, when the annular plate 6 rotates, the rectangular lifting plate 10 , the scraper 11 , and the cleaning brush 12 are driven to rotate synchronously, thereby cleaning the inner wall of the peripheral side of the mixing drum 1 , and effectively performing a cleaning operation on the mixing drum 1 .

[0033] like Figure 3 As shown, the limiting assembly includes a limiting ring 17, which is fixedly mounted on the inner wall of the bottom end of the mixing drum 1. An arc groove matched with the limiting ring 17 is provided at the bottom of the rectangular lifting plate 10. When in use, when the rectangular lifting plate 10 is lowered to a suitable position, the matching function of the arc groove and the limiting ring 17 is used to limit the rectangular lifting plate 10 to prevent the rectangular lifting plate 10 from deformation during rotation.

[0034] Specifically, when the rectangular lifting plate 10 moves downward to a suitable position, the arc groove provided at the bottom of the rectangular lifting plate 10 can be used to limit the position with the limiting ring 17, and the limiting effect can effectively prevent the rectangular lifting plate 10 from deforming during rotation.

[0035] like Figure 1 As shown, a liquid level meter 18 is fixedly installed on the peripheral outer wall of the mixing drum 1. The advantage of such an arrangement is that the liquid level height of the slurry in the mixing drum 1 can be monitored by the arrangement of the liquid level meter 18.

[0036] Specifically, by providing the liquid level meter 18 , it is possible to monitor the liquid level of the slurry in the mixing drum 1 , thereby preventing the internal components from being damaged due to an excessively high liquid level.
