Power battery recycling refers to the recycling and reuse of power batteries that are scrapped, damaged or no longer used. The recycling of waste power batteries can promote the sustainable use of resources, reduce environmental pollution, save energy, reduce costs and promote a circular economy. For the recycled power batteries, one of the processing steps is to crush and grind them, which requires the use of crushing and grinding equipment. The patent with application number CN202221989044.8 discloses a lithium-ion battery crushing and recycling device. The battery crushing and recycling device can better crush lithium-ion batteries and improve the quality of lithium-ion battery crushing. However, the lithium-ion battery crushing and recycling device still has the following disadvantages: 1) The lithium-ion battery is transferred to the feed hopper through the feeding mechanism, and enters the crushing box through the feed hopper for crushing. The lithium-ion batteries that enter the crushing box for crushing in this feeding method can only be The crushing mechanism is crushed at one position, that is, the position of the crushing mechanism below the feed hopper. This can easily cause the lithium-ion batteries that enter the crushing box one after another to get stuck in the crushing mechanism and damage the crushing mechanism. If the conveying speed of the feeding mechanism is slowed down to prevent the crushing mechanism from getting stuck, the crushing efficiency of the battery will be greatly reduced. In addition, the rest of the crushing position on the crushing mechanism often does not play the role of crushing the battery, and the crushing mechanism cannot be fully utilized; 2) Although the crushing recovery device can crush lithium-ion batteries, it cannot grind lithium-ion batteries and cannot meet the grinding level requirements.

The used power batteries enter the crushing and grinding box 6 from the feed hopper 7 for crushing and grinding, wherein the used power batteries pass through the first crushing structure 7, the second crushing structure 8 and the grinding structure 9 from top to bottom in sequence. After the used power batteries pass through the first crushing structure 7 and the second crushing structure 8, the crushing effect is greatly improved. The crushed used power batteries enter the grinding structure 9 for grinding, and the ground used power batteries are discharged from the discharge port 11. During the entire crushing and grinding process , the crushing and grinding mechanism 3 always slides left and right along the bottom plate 1, wherein the right end of the transmission frame 2 extends to the right all the time, leaving enough space for the crushing and grinding mechanism 3 to slide to the left. When the crushing and grinding mechanism 3 slides to the leftmost side, the left end of the crushing and grinding box 6 does not contact the rightmost supporting leg of the transmission frame 2, and the rightmost end of the transmission frame 2 is close to the rightmost end of the feed hopper 10 but does not exceed the rightmost end of the feed hopper 10. When the crushing and grinding mechanism 3 slides to the rightmost end, the rightmost end of the transmission frame 2 is close to the leftmost end of the feed hopper 10 and exceeds the leftmost end of the feed hopper 10. During the entire crushing process, the crushing and grinding mechanism 3 always moves left and right at a certain speed. This left and right The moving process enables the used power batteries on the transmission rack 2 to evenly enter the crushing and grinding box 6 for crushing, that is, they can be evenly distributed on the first crushing structure 7 and the second crushing structure 8, and will not be fixedly concentrated at one position of the first crushing structure 7 and the second crushing structure 8 for crushing. In this way, the used power batteries can be evenly crushed on the first crushing structure 7 and the second crushing structure 8, and efficient crushing is achieved under the premise of preventing material jamming. At the same time, the arrangement of the first crushing structure 7, the second crushing structure 8 and the grinding structure 9 not only achieves a good crushing of the used power batteries, but also achieves a good grinding.

[0022] There are four supporting legs 5, which are fixed at the four corners of the fixed plate 4 respectively, and a material receiving frame 12 is provided on the fixed plate 4. This arrangement not only provides good support for the crushing and grinding box 6, but also allows a relatively large material receiving frame 12 to be placed under the crushing and grinding box 6, which is convenient for receiving materials.

[0023] The fixed plate 4 is movably connected to the base plate 1 through a screw structure 13. The screw structure 13 includes a first motor 14 fixed to the right end of the base plate 1. A screw 16 is fixed to the first rotating shaft 15 of the first motor 14. The screw 16 is provided with a nut seat 17 matching the screw 16. The fixed plate 4 is fixed to the nut seat 17. The left end of the screw 16 is rotatably connected to a fixed seat 18. The fixed seat 18 is fixed to the base plate 1. The left and right movement of the crushing and grinding mechanism 3 is achieved through the screw structure 13.

[0024] The first crushing structure 7 includes a second motor 19 fixed on the right side wall of the crushing and grinding box 6, a first connecting shaft 21 extending into the crushing and grinding box 6 is fixed on the second rotating shaft 20 of the second motor 19, a driving gear 22 is fixed on the right end of the first connecting shaft 21, and the driving gear 22 is meshed with a driven gear 23, and the driven gear 23 is fixed on the second connecting shaft 24, and the second connecting shaft 24 extends into the crushing and grinding box 6, and a first crushing roller 25 and a second crushing roller 26 are respectively fixed on the first connecting shaft 21 and the second connecting shaft 24 in the crushing and grinding box 6, wherein the left ends of the first connecting shaft 21 and the second connecting shaft 24 are both rotatably connected to the left inner wall of the crushing and grinding box 6, and a plurality of crushing blades are fixed on the outer surfaces of the first crushing roller 25 and the second crushing roller 26 to achieve crushing of the waste power batteries. When working, the second motor 19 is started to drive the first crushing roller 25 and the second crushing roller 26 to rotate towards each other, thereby achieving crushing of the waste power batteries. It should be noted here that the structures of the second pulverizing structure 8 and the first pulverizing structure 7 are the same, so the specific structure of the second pulverizing structure 8 will not be described in detail here.

[0029] Working principle: during operation, the recycled used power batteries are first placed one by one on the transmission rack 2, and the transmission rack 2 transmits the used power batteries to the feed hopper 7. The used power batteries enter the crushing and grinding box 6 from the feed hopper 7 for crushing and grinding, wherein the used power batteries pass through the first crushing structure 7, the second crushing structure 8 and the grinding structure 9 from top to bottom in turn. After the used power batteries pass through the first crushing structure 7 and the second crushing structure 8, the crushing effect is greatly improved, and the crushed used power batteries enter the grinding structure 9 for grinding, and the ground used power batteries are discharged from the discharge port 11. During the entire crushing and grinding process, the crushing and grinding mechanism 3 always slides left and right along the bottom plate 1, wherein the right end of the transmission rack 2 extends to the right all the time, leaving enough space for the crushing and grinding mechanism 3 to slide to the left, and when the crushing and grinding mechanism 3 slides to the leftmost side, the left end of the crushing and grinding box 6 does not contact the rightmost support leg of the transmission rack 2, and the rightmost end of the transmission rack 2 Close to the rightmost end of the feed hopper 10 but not exceeding the rightmost end of the feed hopper 10, when the crushing and grinding mechanism 3 slides to the rightmost end, the rightmost end of the transmission frame 2 is close to the leftmost end of the feed hopper 10 and exceeds the leftmost end of the feed hopper 10. During the entire crushing process, the crushing and grinding mechanism 3 always moves left and right at a certain speed. This left and right movement process allows the waste power batteries on the transmission frame 2 to evenly enter the crushing and grinding box 6 for crushing, that is, they can be evenly distributed on the first crushing structure 7 and the second crushing structure 8, and will not be fixedly concentrated at one position of the first crushing structure 7 and the second crushing structure 8 for crushing. In this way, the waste power batteries can be evenly crushed on the first crushing structure 7 and the second crushing structure 8, and efficient crushing is achieved under the premise of preventing material jamming. At the same time, through the arrangement of the first crushing structure 7, the second crushing structure 8 and the grinding structure 9, not only the waste power batteries are well crushed but also well ground.
