Description
Technical field
The present invention relates to stagewise lithium ion battery terminal cutting method and devices under a kind of liquid, for applying waste lithium ionic electricity
Terminal excision in the regenerative process of pond.
Background technique
By the end of the year 2017, China is accumulative to promote new-energy automobile more than 180 ten thousand, assembles power accumulator about 86.9
GWh, it is retired will to enter scale for new-energy automobile power accumulator after 2018, it is contemplated that accumulative by 2022 will be more than 400,000
Ton.Waste and old lithium ion battery is put into National Hazard waste register, and random heap, which outcasts the soldier, causes extremely seriously big gas and water and soil
Pollution, while also resulting in the significant wastage of valuable resource.It is socio-economic development that waste battery, which is carried out cleaning recycling,
Necessary demand.The key link of waste and old lithium ion battery recycling and reusing is the dismantling of battery, moves back applying waste lithium ionic complexity
It still has a surplus after very high, retired electricity, and organic, the fluorine-containing electrolysis big and inflammable containing the active elemental lithium of chemical property and pollution
Liquid, these substances encounter water and oxygen easily burns, these attributes are that the safe disposal of retired lithium dynamical battery is brought very greatly
Difficulty.Waste and old power battery can generate high temperature during dismantling, and there are toxic exhaust emissions, easily shape during dismantling
At short circuit, battery catches fire is caused to explode, there is biggish environmental pollution and security risk, these problems during Dismantlement
It is extremely inconvenient when battery recycling being caused to recycle or disassemble.Existing old and useless battery dismantling process domestic at present is lacked there are following
Point：1）The entire dismantling discontinuous production of process, inefficiency；2）The organic matters such as battery core electrolyte inside have in integrally dismantling
The hidden danger of burning, explosion, dismantling may need low temperature environment, but frozen cooling cost is again very high, be not suitable for the dynamic of high capacity
The dismantling of power battery.3）During dismantling, operator is likely to be exposed the liquid of waste cell and sucking pernicious gas, harm health.Cause
This lithium ion battery recycles industry there is an urgent need to automate the disassembling technology of high safety environmental protection, really realizes power battery energy-saving ring
It protects, is safe and reliable, efficiently dismantling recycling.
Summary of the invention
The purpose of the present invention is to provide stagewise lithium ion battery terminal cutting method and devices under a kind of liquid, realize useless
The safety of lithium ion battery, standardization dismantling.
The technical scheme is that：

Except process is in liquid-immersed lower completion, completely cuts off air and water, specifically comprise the following steps：
The lithium ion battery scrapped first is classified by geometric dimension, is immersed in liquid, battery is fastened laggard by Sequentially continuous
The excision of row terminal, excision process classification is carried out, is cut off by the outermost two rows terminal in two sides, step by step inwardly, until cutting off all
After terminal, terminal and battery separation, the subsequent processing link of terminal and battery is respectively enterd.
Further, the liquid for submerging battery is one of dibutyl carbonate, carbonic acid dioctyl ester and diphenyl carbonate
Or it is two or more.
A kind of device for terminal excision, including transmission belt, binding clip, rope saw and protection liquid storehouse, the fastening
Clamping plate includes upper clamp plate and lower clamp plate, and binding clip is set to the two sides of transmission belt, and several pieces set between upper clamp plate and lower clamp plate
Rope saw is set, the rope saw is several grades, and the system of transmission belt, binding clip and rope saw composition is immersed in the liquid level in protection liquid storehouse
Below.
Further, rope saw is two-stage or more.
The beneficial effects of the present invention are：
Method of the invention cuts off the terminal of scrap lithium ion battery step by step under conditions of exclusion of water and oxygen, does not need advanced
The remaining electric treatment of row, can be realized continuous production, and technique is very simple, and thoroughly, high production efficiency is practical for terminal excision,
Safety and environmental protection, production capacity are big.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of apparatus of the present invention.
Fig. 2 is process flow diagram of the invention.
Specific embodiment
As shown in Figure 1, device of the present invention, including transmission belt 1, binding clip, rope saw and protection liquid storehouse 7, tightly
Gu clamping plate includes upper clamp plate 2 and lower clamp plate 3, binding clip is set to the two sides of transmission belt 1, several pieces of upper clamp plates and lower clamp plate it
Between setting rope saw, the described rope saw is several grades, and the system of transmission belt 1, binding clip and rope saw composition is immersed in protection liquid storehouse 7
Liquid level below.
The present invention will be further explained below with reference to the attached drawings and specific examples.
Embodiment 1：Carbon is immersed by Sequentially continuous after the rectangle lithium ion battery scrapped first is classified by geometric dimension
In dibutyl phthalate maceration extract, it is arranged successively transmission belt 1, the binding clip of 1 two sides of transmission belt is fixedly clamped the end of battery respectively
