Description

[0002] In the production process of lead-acid batteries, there is a process of adding sulfuric acid to the battery. Due to process requirements (sulfuric acid is injected into the battery, acid-base chemistry will occur between the sulfuric acid and the plates, generating a large amount of heat, causing the battery to heat up sharply, affecting the battery charging effect), the added sulfuric acid is frozen acid liquid, and the acid temperature needs to be controlled below zero degrees, which requires strict control of the acid temperature change during the acid injection process. At present, during the rest period of the battery acid injection process (stopping for more than 0.5 hours), in order to prevent the acid temperature from rising, the operation requires that the sulfuric acid in the sleeve and casing of the acid injection mechanism needs to be manually drained, the sulfuric acid is collected in a container, and then put back into the frozen acid barrel. This process will increase the labor intensity of the workers, and the acid temperature will also increase, resulting in a waste of resources.
