Technical Field

[0001] The utility model belongs to the technical field of lithium battery recycling and processing, and in particular relates to a screening device for lithium battery recycling and processing. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries are primary batteries and are not rechargeable.

[0003] During the recycling process of lithium batteries, the lithium batteries need to be crushed and screened through a screening device. However, due to the large amount of crushed materials screened by the existing screening device, the feed port cannot discharge materials in time, which will cause the feed port to be blocked. In addition, when the existing screening device is screening, the crushed materials are easily stuck in the filter holes of the filter plate, thereby clogging the filter plate and making the device unable to work normally.

Afterwards, when the eccentric block 402 is separated from the fixed plate 407, the second spring 406 drives the fixed plate 407 to move upward by releasing the elastic force, and drives the sliding rod 405 to strike the bottom of the filter plate 12, so that the crushed materials stuck in the filter hole of the filter plate 12 can be knocked down, avoiding the crushed materials stuck in the filter hole and causing the filter plate 12 to be blocked, thereby ensuring the normal operation of the device.
