Lead-acid battery electrolyte extraction device

Abstract

The invention relates to the technical field of electrolyte extraction, and discloses a lead-acid battery electrolyte extraction device, which comprises a fixed bottom plate, an extraction box mountedin the middle of the upper end of the fixed bottom plate, support frames mounted on two sides of the upper end of the fixed bottom plate, a support plate mounted at the top ends of the support frames, and a rotating shaft mounted in the middle of the upper end of the support plate through a bearing; the upper end of the rotating shaft penetrates through the supporting plate to be connected with agear set, a rotating shaft is installed in the middle of the gear set, a first crank is arranged in the middle of the left side of the rotating shaft, a first sliding sleeve is arranged in the middleof the first crank, and a first connecting rod is installed at the lower end of the first sliding sleeve. According to the battery pack puncture device, a puncture shaft can puncture and punch a battery pack while moving up and down, flowing-out of an electrolyte is facilitated, and meanwhile, the negative pressure box is arranged, so that the flowing-out speed of the electrolyte in a battery isfurther increased.

Description

technical field [0001] The invention relates to the technical field of electrolyte extraction, in particular to a lead-acid battery electrolyte extraction device. Background technique [0002] During the dismantling process of lithium-ion batteries, due to the residual power of the materials, the batteries may cause natural explosions under high temperature, pressure, electric sparks and other factors, especially power batteries. In recent years, new energy electric vehicles have used a large number of lithium-ion batteries, but in actual use, there have been problems with battery failure, and many problems with battery failure are caused by changes in the electrolyte inside the battery. Therefore, it is necessary to study and analyze the change of the electrolyte composition in the failed battery to determine the cause of the battery failure, so it is necessary to extract and analyze the electrolyte in the failed battery. [0003] At present, there are few devices used to ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are few devices used to extract the electrolyte in the failed lithium-ion battery, and the existing electrolyte recovery device is not suitable for the extraction of the electrolyte in the failed battery, which has the problems of high equipment requirements, complicated operation and easy pollution

[0004] Chinese patent (Notice No.: CN205808761U) discloses an electrolyte extraction device for a failed lithium-ion battery, including an electrolyte extraction chamber, a nitrogen tank for filling the electrolyte extraction chamber with nitrogen, a vacuum pump for vacuuming the electrolyte extraction chamber, and an electrolysis chamber. Liquid collection bottle, the inside of the electrolyte extraction chamber is provided with an ultrasonic elution tank, the top of the pool mouth of the ultrasonic elution tank is provided with a solvent injection pipe connected to it, and the bottom of the ultrasonic elution tank is provided with an electrolyte collection bottle. The discharge pipe of the electrolyte extraction chamber is also provided with a door and a pressure gauge, and the nitrogen tank, vacuum pump and electrolyte collection bottle are all arranged outside the electrolyte extraction chamber, although the device can To a certain extent, the effective extraction of the electrolyte inside the battery is realized, but in actual operation, the electrolyte cannot be extracted effectively and quickly, and the extraction efficiency and effect are poor. Therefore, further improvement is needed
