An inclined bar 29 is fixedly installed on each dragging bar 28. By conveying the lithium battery to be crushed into the cabin 1 through the feeding hopper 11, the rotation drive 4 can drive the rotation of the rotating column 16, thereby driving the crushing block 17 to rotate rapidly to crush the lithium battery. Then the crushed lithium battery will fall into the filter pipe 19. At the same time, the rotating motor 10 can drive the rotation of the filter pipe 19 through the cooperation of the rotating rod 39 and the gear 40 with the rack 20. In this way, the filter pipe 19 can drive the dragging bar 28 to move, so that the debris that cannot pass through the filter pipe 19 can be conveyed upward.

A weight strip 14 is fixedly installed on the baffle 15. By moving the square box 7 to the right, the three square air pipes 13 are brought into contact with the filter pipe 19. Then, air can be injected into the air supply pipes 6 through the air supply device. In this way, the air can be blown onto the filter pipe 19 through the three square air pipes 13, so that the filter pipe 19 can be cleaned, thus avoiding blockage of the filter pipe 19 caused by long-term use.

[0039] A recycling method for a waste lithium battery recycling device is as follows:

[0040] S1: The lithium battery to be crushed is conveyed into the cabin body 1 through the feeding hopper 11, and at the same time, the rotation drive 4 is started, so that the lithium battery can be quickly crushed by the crushing block 17.

[0041] S2: Starting the rotating motor 10 can drive the rotating pipe 19 to rotate through the cooperation of the rotating rod 39 and the gear 40 with the rack 20, so as to sort out the unqualified debris and crush the unqualified debris again at the same time.

[0042] S3: The rotating motor 10 can drive the rotating pipe 19 to rotate counterclockwise through the cooperation of the rotating rod 39 and the gear 40 with the rack 20, convey the debris to the upper right, and the debris slides downward from the upper right. The debris will slide onto the inclined plate 12, so that the debris can successfully slide between the two rotating columns 16.

[0043] S4: Move the square box 7 to the right to make the three square air pipes 13 fit with the filter pipe 19, and then inject air into the filter pipe 19 through the air supply device through the air supply pipe 6, so that the air can blow to the filter pipe 19 through the three square air pipes 13 to clean the filter pipe 19.

[0044] S5: When the filter tube 19 rotates, it can drive each moving rod 32 to rotate and move. When the moving rod 32 moves to the triangular block 26, the two movable balls 35 cooperate with the inclined surface of each triangular block 26 to make the moving rod 32 move back and forth, so as to drive each movable bar 27 to move back and forth, and at the same time drive each small column 38 to move back and forth to stir the debris.

[0045] In use, the first step: The lithium battery to be crushed is conveyed into the cabin 1 through the feed hopper 11. By rotating the drive 4, the rotating column 16 can be driven to rotate, so as to drive the crushing block 17 to rotate rapidly to crush the lithium battery. Then the crushed lithium battery will fall into the filter tube 19. At the same time, the rotating motor 10 can drive the rotating tube 19 to rotate through the rotating rod 39 and the gear 40 cooperating with the rack 20. In this way, the filter tube 19 can drive the drag bar 28 to move, so as to convey the debris that cannot pass through the filter tube 19 upward. Then when the drag bar 28 moves to the upper part, the debris will slide downward, so that the unqualified debris can be re-crushed. In this way, the unqualified debris can be sorted out and re-crushed at the same time.

[0046] The second step: The filter tube 19 can be supported by two support rings 31 cooperating with the annular wall groove 30, and at the same time, the rotation of the filter tube 19 is not affected, so that the debris can be filtered and conveyed at the same time.

[0047] The third step: The rotating motor 10 can drive the rotating tube 19 to rotate counterclockwise through the rotating rod 39 and the gear 40 cooperating with the rack 20. In this way, the debris can be conveyed to the upper right, and then the debris will slide downward from the upper right. In this way, the debris will slide onto the inclined plate 12, so that the debris can successfully slide between the two rotating columns 16.

[0048] The fourth step: By moving the square box 7 to the right, the three square air pipes 13 are fitted with the filter tube 19. Then air can be injected into the filter tube 19 through the air supply device through the air supply pipe 6. In this way, the air can blow to the filter tube 19 through the three square air pipes 13, so as to clean the filter tube 19 and avoid blockage of the filter tube 19 caused by long-term use. When not cleaning, the mechanisms such as the square box 7 can be pulled out, and then the baffle 15 can be turned over to block the square pipe 8.

[0049] The fifth step: When the filter tube 19 rotates, it can drive each moving rod 32 to rotate and move. When the moving rod 32 moves to the triangular block 26, the two movable balls 35 cooperate with the inclined surface of each triangular block 26 to make the moving rod 32 move back and forth, so as to drive each movable bar 27 to move back and forth, and then drive each small column 38 to move back and forth, so as to stir the debris and avoid large debris blocking a large amount of debris that can pass through the filter tube 19 and affecting the filtering efficiency.
