[0003] However, there is at least one of the following problems in the related art: in the prior art, the crushed lithium battery waste is easily clogged at the feed port of the reaction chamber when entering the reaction chamber, resulting in reduced feeding efficiency and thus reduced lithium battery recovery efficiency. Utility Model Content

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: the utility model optimizes the separation process of lithium battery waste by the first screening chamber and the second screening chamber arranged upper and lower. The large-particle lithium battery waste that is easy to cause blockage will be retained in the first screening chamber after being screened by the screen plate, and discharged through the first discharge port; while the small-particle waste that is not easy to cause blockage will enter the second screening chamber through the sieve hole after being screened in the first screening chamber, and then be discharged through the second discharge port, which effectively improves the feeding efficiency.

[0009] In one embodiment of the present invention, the sieve plate is arranged at an angle a with the horizontal plane.

[0022] In one embodiment of the present invention, the lithium battery recycling and scrapping device further includes a heating device, which is disposed at the bottom of the reaction component to heat the reaction component.

[0023] By adopting the technical solution of the utility model, the following technical effects can be achieved: the reaction component is heated by the heating component, thereby further improving the reaction efficiency of the lithium battery waste in the reaction component, thereby improving the recycling efficiency of the lithium battery.
