[0023] like Figure 1 、 2The gear 13 is meshed with the gear 16 when the filter barrel 6 is lifted up, and the meshing gear 13 is rotated. The gear 13 is rotated, and the gear 13 drives the drum 12 to rotate. The stirring plate 15 is provided with a stirring plate 15, and the stirring plate 15 is provided with a through hole 25 to reduce the resistance to the rotation of the stirring plate 15. At the same time, it does not affect the stirring plate 15 from rotating to stir and disturb the aluminum liquid in the filter barrel 6. A gear column 16 is rotatably provided on the bracket 3 and is meshed with the gear 13. A motor 17 is provided on the support plate 4 and is power-connected with the gear column 16. The length of the gear column 16 can meet the requirement that the gear 13 can still maintain a meshing relationship with the gear column 16 when the filter barrel 6 is lifted up from the filter box 2. The gear column 16 rotates, and the meshing gear 13 rotates. The gear 13 drives the drum 12 to rotate, and the stirring plate 15 can stir the aluminum liquid in the filter barrel 6. The aluminum liquid is in a flowing state, which will speed up the filtration speed in the filter barrel 6.

[0024] like Figure 1 and 3 The lifting drive device 5 includes an inner wire drum 18, which is buckled and rotated in the support plate 4. A gear three 19 is provided on the inner wire drum 18, and a motor two 20 is provided on the support plate 4.
