Automatic acid-adding device for lead-acid storage battery

Abstract

The invention discloses an automatic acid-adding device for a lead-acid storage battery. The automatic acid-adding device comprises an electrolyte preparing device and an acid-adding device for the lead-acid storage battery, wherein the acid-adding device for the lead-acid storage battery comprises an electric pump and a liquid storage box; a water outlet of the electric pump is connected with a water discharging pipe; the other end of the water discharging pipe is connected with an acid injecting head; the acid injecting head comprises a shell, and one end of the shell can be connected with an acid injecting port of the storage battery; the shell is internally provided with an acid injecting pipe; one end of the acid injecting pipe is connected with the water discharging pipe; the shell is also internally provided with a rod body, and the lower end of the rod body can float on the liquid level of acid liquid; the rod body is provided with a branch rod; a box body is arranged on the outer wall of the shell; the bottom part of the box body is provided with an elastic clamping piece and a first contact for communicating with a power line; and one end of the branch rod penetrates through a wall body of the shell and extends into the box body. The automatic acid-adding device disclosed by the invention has the advantages that the preparation of electrolyte with the set concentration can be carried out automatically, and the rated acid adding amount is automatically finished when the acid is added, so that the excessive acid addition is prevented.

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
