Abstract
The invention relates to the technical field of lithium batteries, in particular to a recycling method for residual slurry for a lithium battery. Through movement of a sealed rubber piston in a pipeline, the residual slurry in the pipeline is completely pressed into a temporary storage tank, so that waste of the slurry is reduced; generation of a pollutant is avoided; and meanwhile, the cost of the battery is also reduced.
Description
Technical field
The present invention relates to technical field of lithium batteries, be specifically related to a kind of recoverying and utilizing method of residual lithium battery slurry.
Background technology
The production of current lithium battery all enters the production process of serialization, Cemented filling and the filtration that the coating being accomplished to coating machine all adopts sealed type is prepared from slurry, due to the layout of production equipment, the length of slurry transport lines can reach 50-60m, and some duct lengths are even longer; In addition due to reasons such as product type switching or plant maintenances, certainly exist the situation that coating machine is shut down; A collection of like this slurry is from bringing into use finally terminating, and with the carrying out of coating process, the slurry in slurry can, progressively in minimizing, arrives slurry residual in last only remaining pipeline.Because slurry residual in pipeline is when carrying, does not fill up pipeline completely, can there is a large amount of air in pipeline, when being coated with, pole piece there will be a large amount of bubbles, crackle etc. are abnormal, thus cause coating to occur a large amount of waste products; The common practice is at the end of coating is fast, to slurry residual in pipeline by scrapping process, the cost of battery will be caused like this to increase.Patent of the present invention is placed in pipeline based on airtight rubber piston, promotes to move rubber piston and the slurry in pipeline is all expressed into temporary storage tank, be more all coated with by compressed air.
Summary of the invention
The object of the invention is to solve the problem, a kind of recoverying and utilizing method of residual lithium battery slurry is provided.
In order to reach foregoing invention object, the present invention by the following technical solutions:
A kind of recoverying and utilizing method of residual lithium battery slurry, the device that described method adopts is: this device comprises storage tank and temporary storage tank, be connected with temporary storage tank top by feeding pipe bottom storage tank, storage tank is provided with liquid level gauge, be connected with dispense tip by feeding pipe bottom temporary storage tank, feeding pipe bottom storage tank is provided with membrane pump, membrane pump is connected with compressed air by pipeline, feeding pipe on rear side of membrane pump is provided with quick union, be positioned at quick union place and be provided with rubber piston, the rear end of rubber piston is connected with compressed air by pipeline;
Its step specifically comprises:
1) open compressed air, open membrane pump, the slurry in storage tank is driven in temporary storage tank;
2) opening coating machine makes slurry transferring in temporary storage tank to dispense tip;
3) along with the carrying out of coating, in storage tank, slurry gradually reduces, and when the display of liquid level gauge is close to during at " 0 " scale, closes membrane pump, closes compression air;
4) open quick union, rubber piston is put into slurry pipe road junction, open compressed air, rubber piston is compressed into feeding pipe, by the movement of rubber piston in feeding pipe, the slurry in pipeline is all pressed in temporary storage tank.
Preferably, described rubber piston and feeding pipe match.
Preferably, blender is provided with in described storage tank.
Preferably, described liquid level gauge is positioned at the bottom of storage tank.
Compared with prior art, this programme is by the movement of caulking gum piston in pipeline, and by the slurry remained in pipeline, whole is pressed onto in temporary storage tank, decreases the waste of slurry, avoids the generation of pollutant, also reduces battery cost simultaneously in the present invention.
