A discharge mechanism 4 is assembled inside the cleaning tank 2. The crushing device 1 is a common crusher in the prior art and can crush aluminum shells. Acidic solutions such as phosphoric acid can be stored inside the cleaning tank 2 to remove the aluminum oxide film on the outside of the aluminum shells. The discharge port 3 can discharge the aluminum shells from which the aluminum oxide film has been removed.

[0024] Please refer to Figure 3 , the discharge mechanism 4 includes a filter plate 41 and a limiting plate 49. The filter plate 41 is slidably arranged inside the cleaning tank 2. The limiting plate 49 is assembled on both sides inside the cleaning tank 2. Holes are evenly distributed at the bottom of the filter plate 41 for solid-liquid separation. A cylinder 42 is assembled at the bottom of the filter plate 41. A C-shaped plate 43 is inserted inside the filter plate 41. Springs 44 are evenly distributed between the C-shaped plate 43 and the filter plate 41. Both outer sides of the C-shaped plate 43 are connected by hinges to a connecting rod 45, and the other end of the connecting rod 45 is connected by a hinge to a pushing plate 46.

[0025] The bottom of the cylinder 42 is connected to the inner bottom of the cleaning tank 2 by bolts. A protective sleeve is sleeved outside the cylinder 42. The protective sleeve prevents the cylinder 42 from being eroded by acid liquid. First track grooves 47 are provided on both outer sides of the C-shaped plate 43. The first track grooves 47 are slidably connected to the filter plate 41. The first track grooves 47 can guide the C-shaped plate 43 to move linearly outside the filter plate 41. At the same time, track blocks adapted to the first track grooves 47 and capable of sliding inside the first track grooves 47 are assembled at both ends outside the filter plate 41. Second track grooves 48 are provided on both sides at the top of the filter plate 41.

[0026] The second track groove 48 is slidably connected to the push plate 46. The second track groove 48 can guide the push plate 46 to perform linear motion. Track blocks that are adapted to the second track groove 48 and can slide inside the second track groove 48 are assembled on both sides of the bottom of the push plate 46. The air cylinder 42 can drive the filter plate 41 to rise. The U-shaped plate 43 can perform linear motion outside the filter plate 41. The spring 44 can drive the U-shaped plate 43 to return after movement. The connecting rod 45 can be driven by the U-shaped plate 43 to带动 the push plate 46 to perform linear motion on the top of the filter plate 41.

[0027] Please refer to Figure 4 , a separation mechanism 5 is assembled outside the cleaning tank 2. The separation mechanism 5 includes a separation box 51. The separation box 51 is connected to the cleaning tank 2. Bent pipes 53 are evenly arranged at the bottom of the separation box 51, and the other ends of the bent pipes 53 are connected to the cleaning tank 2. A collection box 52 is assembled on the top of the separation box 51. Flow guide plates 54 are connected to both ends inside the separation box 51.

[0028] The outside of the flow guide plate 54 is polished. The flow guide plate 54 can guide the drained acid solution to be discharged through the bent pipe 53. Magnets are assembled on the outside of both the collection box 52 and the separation box 51. The bottom of the collection box 52 is designed with an opening. The magnet can make the collection box 52 placed on the top of the separation box 51. The separation box 51 cooperating with the bent pipe 53 can re-drain the collected acid solution into the inside of the cleaning tank 2. The collection box 52 can collect the aluminum shells and drain the acid solution on the outside of the aluminum shells.

[0029] In this solution, first, the defective battery aluminum shells are directly put into the inside of the crushing device 1. The crushing device 1 is started to crush and process the battery aluminum shells. The crushed battery aluminum shells fall onto the top of the filter plate 41 inside the cleaning tank 2. Acidic solutions such as phosphoric acid are filled into the inside of the cleaning tank 2 to remove the aluminum oxide film. After all the battery aluminum shells are crushed, the crushing device 1 is turned off and the air cylinder 42 is started to带动 the filter plate 41 to rise. The rising filter plate 41带动 the U-shaped plate 43 to move together. When the U-shaped plate 43 contacts the limit plate 49, the U-shaped plate 43 descends, and then带动 the connecting rod 45 to drive,带动 the push plate 46 to move, and push the battery aluminum shells on the top of the filter plate 41, and discharge them through the discharge port 3 into the inside of the collection box 52 for collection. At the same time, the acid solution on the outside of the battery aluminum shells will enter the inside of the separation box 51 through the bottom of the collection box 52, and be re-drained into the inside of the cleaning tank 2 through the guiding of the flow guide plate 54 and the cooperation of the bent pipe 53 for collection;

[0030] When the battery aluminum shell is being recycled, the aluminum oxide film on the outside of the battery aluminum shell is removed through the added discharge port 3 in combination with the acidic solution to prevent the battery aluminum shell with the aluminum oxide film from affecting the purity of the subsequently recycled aluminum plate. At the same time, through the added discharge mechanism 4, when the aluminum oxide film on the outside of the battery aluminum shell is removed, the battery aluminum shell is automatically discharged through the discharge port 3 into the interior of the separation mechanism 5 for closed discharge to prevent the acidic solution from causing damage to external metal machinery and staff. At the same time, after collecting the battery aluminum shell, the separation mechanism 5 automatically recovers the filtrate of the acidic solution on the outside of the battery aluminum shell to avoid waste of the acidic solution and avoid excessive acidic solution in the battery aluminum shell causing inconvenience in subsequent processing.
