Problems solved by technology

[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

Embodiment Construction

[0036] like Figure 1-13 As shown, a lithium battery recycling process includes the following steps:

[0037] a. First, discharge the lithium battery;

[0038] b. Disassemble the lithium battery after the discharge treatment in a, and recycle the disassembled casing;

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

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

[0041] Wherein, the recycling device described in step d includes a main body 1, a first motor 2, a rotating plate 3, a pulverizing device 4, a feeding port 5, a sealing device 6, and a sorting device 7; the pulverizing device 4 includes a U-shaped groove 41. Rack 42, moving block 43, gear 44, rotating roller 45, filter plate 46, pulverizing 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 directl...

Abstract

The invention discloses a lithium battery recovery process, which comprises the following steps: a. first discharge the lithium battery; b. disassemble the lithium battery after discharge treatment in a; c. disassemble the lithium battery in b The electrolyte inside the battery is discharged; d, the lithium battery in c is sent to a sorting and recycling device for crushing and recycling; the recycling device includes a main body, a first motor, a rotating plate, a crushing device, a feeding port, a sealing device, a sorting Device, U-shaped groove, rack, moving block, gear, rotating roller, filter plate, crushing knife, driving mechanism; the discharge treatment of the present invention prevents the waste lithium battery from exploding when it is broken, and improves the safety of lithium battery recycling The crushing device enables the battery to be sieved during crushing, and the metal powder adhered to the metal is separated, which improves the battery recycling efficiency; the sealing device enables the battery to be in a vacuum state during crushing, improving the safety of crushing ; Further improved the effect of battery recycling.

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 to manage the environment, all countries in the world attach great importance to the recycling of waste batteries. The management of waste batteries is urgent. How to make waste batteries resources and harmless is imminent. Most of the existing lithium battery recycling It is to discharge the lithium battery first, and then to break it; however, if the discharge is not complete during the discharge treatment, it is easy to explode when 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 affects recycling efficiency when broken. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, the present invention provides a lithium bat...
