Embodiment Construction

[0036] Such as Figure 1-13 Shown, a kind of lithium battery recycling process comprises the following steps:

[0037] a. First discharge the lithium battery;

[0038] b. Dismantling the lithium battery after discharge treatment in a, and recycling the disassembled shell;

[0039] c. Discharge the internal electrolyte of the disassembled lithium battery in b;

[0040] d. Send the lithium battery discharged from the electrolyte in c to the sorting and recycling device for crushing and recycling;

[0041] Wherein, the recovery device described in the step d includes a main body 1, a first motor 2, a rotating plate 3, a crushing device 4, a feed port 5, a sealing device 6, and a sorting device 7; the crushing device 4 includes a U-shaped groove 41. Rack 42, moving block 43, gear 44, rotating roller 45, filter plate 46, crushing knife 47, driving mechanism 8; the cross section of the main body 1 is circular; the first motor 2 is arranged on the main body 1, which is purchased ...

Abstract

The invention discloses a lithium battery recycling process. The lithium battery recycling process comprises the following steps that a, firstly, a lithium battery is discharged; b, the lithium battery subjected to discharging treatment in the step a is disassembled; c, electrolyte in the disassembled lithium battery in the step b is discharged; and d, the lithium battery in the step c is fed into a sorting and recycling device for crushing and recycling. The recycling device comprises a body, a first motor, a rotating plate, a crushing device, a feeding hole, a sealing device, a sorting device, a U-shaped groove, a rack, a moving block, a gear, a rotating roller, a filtering plate, a crushing cutter and a driving mechanism. According to the lithium battery recycling process, the waste lithium battery cannot explode when being crushed through discharge treatment, so that the safety of lithium battery recovery is improved; the crushing device can realize screening when the battery crushed, so that metal powder adhered to metal is separated, and the battery recovery efficiency is improved; the sealing device can enable the battery to be in a vacuum state during crushing, so that the crushing safety is improved; and the battery recycling effect is further improved.

Description

technical field [0001] The invention belongs to the technical field of battery recycling, and in particular relates to a lithium battery recycling process. Background technique [0002] Due to the shortage of resources and the need for environmental governance, countries all over the world attach great importance to the recycling of waste batteries. The management of waste batteries is urgent. How to make waste batteries resourceful and harmless is imminent. Most of the existing lithium battery recycling Firstly, the lithium battery is discharged and then crushed; however, if the discharge is not complete during the discharge process, it is easy to explode when it is broken; and due to the long-term use of the battery, the positive electrode powder in the battery adheres to the metal sheet Together, it will affect the recovery efficiency when broken. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a...
