An automatic acid adding device for lead-acid battery

Abstract

The invention discloses an automatic acid-adding device for a lead-acid battery, which comprises an electrolyte preparation device and an acid-adding device for a lead-acid battery. The acid-adding device for a lead-acid battery includes an electric pump and a liquid storage tank. The water outlet of the electric pump Connect the water outlet pipe, the other end of the water outlet pipe is connected to the acid injection head, and the acid injection head includes a shell that can be connected to the acid injection port of the battery at one end, and an acid injection pipe is arranged in the shell, and the acid injection pipe One end of the housing is connected with the outlet pipe, and the housing is also provided with a rod body whose lower end can float on the liquid surface of the acid liquid. The bottom of the body is provided with an elastic clip and a first contact connected to the power line, and one end of the pole passes through the wall of the housing and extends into the box. The invention can automatically prepare the electrolyte solution with a set concentration, and automatically complete the rated acid addition amount when adding acid, so as to prevent excessive acid addition.

Description

technical field [0001] The invention relates to an automatic acid adding device for a lead-acid storage battery. technical background [0002] Lead-acid batteries use dilute sulfuric acid as the electrolyte, and the dilute sulfuric acid is diluted to a specific concentration by adding concentrated sulfuric acid to a specific concentration. The existing lead-acid battery electrolyte is usually prepared manually, and a certain amount of concentrated sulfuric acid is mixed and diluted with water by manual measurement. , the efficiency of this preparation method is very low, which is not conducive to mass production, and concentrated sulfuric acid is a dangerous chemical product, which also greatly increases the chance of workers being injured. [0003] During the battery manufacturing process, it is necessary to inject dilute sulfuric acid into the battery as an electrolyte before the battery is formed. The traditional acid addition method uses a simple acid addition device to ...

[0002] Lead-acid batteries use dilute sulfuric acid as the electrolyte, and the dilute sulfuric acid is diluted to a specific concentration by adding concentrated sulfuric acid to a specific concentration. The existing lead-acid battery electrolyte is usually prepared manually, and a certain amount of concentrated sulfuric acid is mixed and diluted with water by manual measurement. , this preparation method is very inefficient and not conducive to mass production, and concentrated sulfuric acid is a dangerous chemical product, which also greatly increases the chance of workers being injured

[0003] During the battery manufacturing process, it is necessary to inject dilute sulfuric acid into the battery as an electrolyte before the battery is formed. The traditional acid addition method uses a simple acid addition device to rely on manual experience to add acid, which often causes the problem of excessive acid addition, which not only affects the battery. Performance, but also cause waste of raw materials, environmental pollution and harm to workers and other issues
