A surface residual electrolyte removal device for waste lithium titanate negative electrode sheet

Abstract

A surface residual electrolyte removal device for a waste lithium titanate negative electrode sheet is disclosed, the device includes a bracket, a material receiving box is fixedly installed at the upper end of the bracket, a material discharge hopper is arranged at the low end of the material receiving box, a rack is fixedly installed on the inner wall of the material receiving box, a plurality of push rod motors are vertically fixedly installed on the rack, the upper ends of the push rod motors are hinged with mounting strips, the upper end of the mounting strips is fixedly installed with abottom plate, a rubber sealing strip which is closely slidably connected with the inner wall of the receiving box is pasted on the outer wall of the bottom plate, and a mesh cylinder is arranged on the upper end of the bottom plate. The beneficial effects are as follows: the urface residual electrolyte removal device for the waste lithium titanate negative electrode sheet can thoroughly remove theelectrolyte and impurities on the surface of the waste lithium titanate negative electrode sheet, ensures that the lithium titanate powder on the waste lithium titanate negative electrode sheet can be completely detached from the aluminum foil without residue, effectively avoids the reduction of the recovery efficiency of the waste lithium titanate negative electrode sheet, and has good practicability.

Description

technical field [0001] The invention relates to the field of recycling waste lithium titanate negative electrodes, in particular to a device for removing residual electrolyte on the surface of waste lithium titanate negative electrodes. Background technique [0002] At present, in the recycling of waste lithium titanate negative electrodes, those waste lithium titanate negative electrodes that have not been injected are generally directly subjected to ultrasonic separation treatment, so that the lithium titanate powder on the lithium titanate negative electrodes falls off from the aluminum foil. , and for those waste lithium titanate negative electrodes that are directly dismantled from scrapped liquid-injected batteries or waste batteries, they need to be calcined before ultrasonic separation can be performed. The electrolyte on the surface of the sheet evaporates, but the impurities in the electrolyte will still remain on the surface of the waste lithium titanate negative ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a device for removing the residual electrolyte on the surface of the waste lithium titanate negative electrode sheet in order to solve the above problems, so as to solve the problem that the method for removing the residual electrolyte solution on the surface of the waste lithium titanate negative electrode sheet by calcination in the prior art cannot Effectively remove the electrolyte impurities on the surface of the waste lithium titanate negative electrode, and the electrolyte impurities will prevent the lithium titanate powder from falling off the aluminum foil, so that the lithium titanate on the surface of the waste lithium titanate negative electrode cannot be completely separated and titanic acid appears Lithium residues lead to problems such as reduced recovery efficiency of waste lithium titanate negative electrodes
