Description

technical field [0001] The invention relates to the field of lead-acid battery production technology and equipment, in particular to a colloidal battery liquid injection process and equipment. technical background [0002] The electrolyte of colloidal lead-acid batteries is generally formed by mixing and stirring dilute sulfuric acid with a certain specific gravity and colloidal additives (for example, dilute sulfuric acid with a specific gravity of 1.270 g / ml at room temperature and colloidal additives are mixed and stirred at a weight ratio of 9:1 to form a colloidal electrolyte. , of course, according to the different types of colloidal additives and colloidal lead-acid batteries, the specific gravity of dilute sulfuric acid and the ratio of dilute sulfuric acid and colloidal additives will also change). Other additives such as sodium sulfate can also be added to the dilute sulfuric acid, and the colloidal additive is generally liquid silicon dioxide, or a liquid formed b...

AI Technical Summary

Problems solved by technology

The disadvantages of this process and equipment are:

[0005] 1. The time from mixing dilute sulfuric acid and colloidal additives to complete solidification is not considered, and the characteristics of accelerating with the increase of temperature are not considered. There is no low-temperature cooling before mixing dilute sulfuric acid and colloidal additives

[0006] 2. The characteristic that the dilute sulfuric acid and colloidal additives start to solidify after mixing is not considered. The colloidal electrolyte mixed in a large container is weighed one by one with ordinary liquid injection equipment, and then injected into multiple batteries separately. In the process of its single cell, because the time interval from the beginning of mixing to the end of the operation of injecting each battery cell is not controlled, the coagulation state of the colloidal electrolyte is already changing, and the colloidal electrolyte of each battery is injected. The solidification state is different

This leads to large differences in the penetration of the colloidal electrolyte into the plates and separators between batteries, and even between cells of multi-cell batteries, which eventually leads to deviations in the consistency of batch batteries, early decay of capacity, and the formation of heat in some batteries. out of control hidden danger

[0007] 3. The production efficiency is low, there is no set of low-temperature cooling of dilute sulfuric acid and colloidal additives, separately metering the dilute sulfuric acid and colloidal additives required for each cell of the battery according to the set ratio, and mixing dilute sulfuric acid and colloidal additives according to the instructions , to the continuous automatic device for injecting the mixed colloidal electrolyte into the battery, it is impossible to efficiently and conveniently realize the process requirement of ensuring that the dilute sulfuric acid and colloidal additives in each battery cell are consistent from the beginning of mixing to the end of the injection
