Embodiment 1

[0031] In the embodiment of the present invention, the oxalic acid liquid washing process is as follows: the electrolyte barrel is placed upside down in a fixed position in the pickling area, the oxalic acid liquid is extracted from the oxalic acid liquid storage tank through the automatic booster pump 4, and transported to the pickling area through pipelines 9 fixed position, sprayed from the automatic rotating nozzle of the water outlet structure 10 in the pickling area 9 to spray the inside of the electrolyte cylinder, after the spray washing is completed, the spray liquid can be discharged through the hollow drainage structure 5 set up in the pickling area 9 for pickling Area;

[0032] Preferably, the spraying liquid discharged through the hollow drainage structure 5 is separated into recyclable oxalic acid solution and spraying wastewater, and the recyclable oxalic acid solution is recycled to the oxalic acid storage tank, and the spraying wastewater can pass through the h...

Embodiment 2

[0059] Such as figure 2 As shown, in the embodiment of the present invention, in the electrolyte barrel cleaning method described above, the electrolyte barrel cleaning process needs to go through incoming barrel inspection, residual liquid recovery, disassembly of parts, parts cleaning, appearance and barrel mouth cleaning, and barrel cleaning. Internal cleaning, drying, assembly, nitrogen replacement, pressure keeping, testing. In the barrel inspection, after the appearance inspection, the barrels that are deformed, damaged, etc. that cannot be used are eliminated, and the electrolyte barrels that meet the secondary use are left in place, and the residual liquid is recovered, and the remaining electrolyte barrels that meet the secondary use are recovered. And remove the pressure in the barrel. For the cleaning of the spare parts, before performing the cleaning process on the electrolyte barrel, the electrolyte barrel needs to be disassembled, and the disassembled spare par...

Embodiment 3

[0062] In the implementation of the present invention, the cleaning process in the electrolyte barrel includes: oxalic acid solution washing process, degreasing liquid washing process, deionized water washing process, ultrasonic cleaning process, and high-purity water washing process. Among them, the process of oxalic acid liquid washing process, degreasing liquid washing process and deionized water washing process is to extract the cleaning liquid through the automatic booster pump 4, transport it to the fixed position of the pickling area 9 through the pipeline, and discharge the water structure 10 from the pickling area 9 The spraying of the automatic rotating nozzle sprays the inside of the electrolyte cylinder. After the spraying is completed, the spraying liquid can be discharged from the pickling area through the hollow drainage structure 5 set in the pickling area 9; the spraying liquid discharged through the hollow drainage structure 5 is passed through Separation and ...

Abstract

The invention discloses an electrolyte barrel cleaning method. The electrolyte barrel cleaning method is a process flow for cleaning an electrolyte barrel which has been used and meets secondary utilization, and the cleaning process flow comprises a cleaning process in the electrolyte barrel, wherein the cleaning process in the electrolyte barrel comprises an oxalic acid liquid washing procedure,a degreasing liquid washing procedure, a deionization water washing procedure, an ultrasonic cleaning procedure and a high-purity water washing procedure. According to the method, multiple proceduresare adopted, the cleaning is automatically controlled, the operation is safe, the cleaning effect is good, the production efficiency is improved, and the deep hole, the thin seam and the workpiece nook can also be cleaned up; no damage is caused to the surface of the workpiece, and the solvent, the heat energy, the working site and the labor are saved. Compared with an existing cleaning method, the whole process of the method is reasonable in layout, smooth in work and high in manual labor intensity reduction degree, high in working efficiency, safe and protected in place, low in equipment cost and capable of solving the problem of difficulty in maintenance.

Description

technical field [0001] The invention relates to the technical field of equipment cleaning, in particular to a method for cleaning an electrolyte bucket. Background technique [0002] Electrolyte is one of the four major raw materials for lithium batteries. The packaging and transportation of electrolyte has extremely high environmental requirements. In order to ensure the quality of electrolyte, it is necessary to control the electrolyte packaging barrel to meet extremely high cleanliness requirements. However, most manufacturers in the industry still use traditional manual cleaning in the process of cleaning packaging barrels. In the lithium battery industry with rapid technological development, the quality requirements are becoming more and more stringent, and the packaging barrels cleaned by hand can no longer meet the quality requirements of the packaging barrels. [0003] The Chinese patent application number: 201510031982.5 discloses a method for cleaning electrolyte ...
