[0002] A lithium battery is a rechargeable battery that uses lithium metal or lithium compounds as the positive electrode material. It utilizes the migration of lithium ions between the positive and negative electrodes during the battery's charge and discharge processes. At the end of life, the spent or depleted lithium batteries are shredded to recover valuable materials for reuse or safe disposal.

[0003] However, there is at least one of the following problems in the related art: the crushing rollers in the prior art do not crush the scrapped lithium batteries thoroughly enough, resulting in particles of different sizes, which causes troubles in subsequent processing. Utility Model Content

[0004] The technical problem solved by the utility model is that the crushing roller in the prior art does not crush the scrapped lithium batteries thoroughly enough, resulting in uneven particle sizes of the crushed materials, which causes troubles in subsequent processing.

[0006] Compared with existing technologies, this technical solution achieves the following technical effects: the crushing component crushes the recycled lithium batteries entering the feed port, which are then screened by the screening component. If the material is not crushed thoroughly enough, it will be screened out by the screening component and then transported to the recycling component. The recycling component then transports it back to the crushing space within the crushing component for multiple crushing operations until the required degree of crushing is achieved. Through multiple crushing and screening, the lithium battery crushed material passing through the screening component is thoroughly crushed and has a uniform particle size.

[0007] In one example of the present invention, the crushing assembly includes: multiple crushing rollers, which are rotatably connected to the shell and are arranged below the feed port; and a crushing barrel, which is arranged in the accommodating space and located below the multiple crushing rollers.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: when recycled lithium batteries of different sizes enter the crushing space from the feed port, they first pass through the crushing roller, are crushed by the crushing roller, and then enter the crushing barrel for secondary crushing; through the dual crushing cooperation of the crushing roller and the crushing barrel, most lithium batteries of different sizes can be stirred and crushed.

[0015] In one embodiment of the present invention, the crushing frame includes: a rotating rod, which is arranged in the crushing barrel and is rotatably connected to the driving motor; and multiple crushing rods, which are evenly arranged on the outer wall of the rotating rod.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the driving motor controls the rotating rod and then controls the rotation of the crushing frame. Multiple crushing rods are arranged around the rotating rod. When the driving motor is started, the crushing rods rotate to crush the material.

[0017] In an embodiment of the present invention, a support platform is provided below the driving motor, and the support platform is fixedly connected to the housing.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the support platform is fixedly connected to the shell, providing support for the crushing barrel and the drive motor, making the crushing assembly more stable.

[0019] In one embodiment of the present invention, a plurality of sieve holes are provided below the sieve element.

[0020] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the sieve holes, when the crushed material passes through the screening element, the material blocks that meet the preset size can pass through the sieve holes, and those that do not meet the size continue to enter the circulation component downward.

[0021] In one embodiment of the present invention, a conveyor belt is further provided in the shell, the conveyor belt is installed in the accommodating space, and the conveyor belt is located below the crushing assembly.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting a conveyor belt in the shell, the material passing through the screening element is conveyed out of the discharge port and enters the next link of lithium battery recycling.
