A vacuum filling electrolyte device for lead-acid batteries

Abstract

The invention discloses a vacuum filling electrolyte device for a lead-acid storage battery, comprising an electrolyte preparation device and a vacuum filling device, the vacuum filling device includes a vacuuming device and a filling device, and the vacuuming device consists of several An assembly formed by connecting bottles whose inner cavities communicate with each other. The lower end of the bottle is provided with an opening that can be sealed and connected with the acid injection port of the battery. The inner cavity of the assembly is connected to a vacuum pump through an exhaust pipe. The device includes a liquid storage tank for storing electrolyte and a water pump. The water inlet of the water pump is connected to the liquid storage tank through the water inlet pipe, and the water outlet of the water pump is connected to the water outlet pipe. A guide tube is arranged in the bottle body, and the guide tube The upper end of the guide tube communicates with the outlet pipe, and the lower end of the draft tube stretches out from the opening. The invention can automatically prepare the electrolyte solution with a set concentration, and when acid is added, the acid solution can smoothly enter the interior of the storage battery, thereby improving the internal formation effect and efficiency of the storage battery.

Description

technical field [0001] The invention relates to a vacuum filling electrolyte device for lead-acid accumulators. [0002] technical background [0003] 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.

Problems solved by technology

[0003] 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

[0004] Filling the battery with dilute sulfuric acid electrolyte is one of the important production processes. After the existing internalized battery is vacuum acid-added by the vacuum acid machine, it takes a process for the separator and plate to absorb acid, and the internal pressure of the battery is too high at this time. , too much acid retained in the acid pot cannot enter the battery smoothly, resulting in less effective acid addition inside the battery

In this way, there is an acid deficiency phenomenon in the initial stage of the battery formation process, and the formation effect is not ideal, which leads to an increase in the probability of a single battery falling behind during use.
