Acid mist filter for charging lead-acid storage battery

Abstract

The invention relates to an acid mist filter for charging lead-acid storage battery. The acid mist filter is particularly suitable for filtering acid mist generated in the storage battery and comprises a filter shell, air inlets, sealing covers, a plurality of filtering air chambers, filtering cotton, filtering cotton mounting brackets, bracket mounting bugles I, bracket mounting bugles II, a filter upper cover and exhausting holes, wherein the filtering air chambers are uniformly distributed in the filter shell, the air inlets are formed in the lower parts of the filtering air chambers, and the sealing covers are mounted at the outer parts of the air inlets; the filtering cotton is mounted on the filtering cotton mounting brackets, two ends of the filtering cotton mounting brackets are respectively obliquely mounted at the bracket mounting bugles I and the bracket mounting bugles II so as to enable acid mist filtered by the filtering cotton to smoothly pass through the air inlets and a liquid injection hole and return to the storage battery, and thus loss of electrolyte is avoided; filtering air chamber mounting troughs are formed in the lower part of the filter upper cover, and the exhausting holes are formed in the upper part of the filter upper cover and are distributed correspondingly to the filtering air chambers arranged in the filter shell.

Description

technical field [0001] The invention relates to an acid mist filter for charging a lead-acid accumulator, which is particularly suitable for filtering the acid mist for internalization of the accumulator. Background technique [0002] In the manufacturing process of lead-acid batteries, especially in the production of traction and stationary batteries, the current relatively advanced battery production technology adopts the production method of internal formation of batteries. Battery internal formation is a production method in which the battery is assembled with raw plates and then activated by charging and discharging. It is necessary to charge 2-7 times the rated capacity of the battery just after adding acid. During the battery formation process, a lot of acid mist gas will be continuously generated and acid mist will overflow, so in the past, the electrolyte solution needs to be replenished manually. At present, the rich liquid pot is mostly installed above the acid ...

AI Technical Summary

Problems solved by technology

At present, the rich liquid pot is mostly installed above the acid injection hole of the battery to replenish the electrolyte and prevent the electrolyte from overflowing. However, the structure of the rich liquid pot is too simple to handle acid mist, and a large amount of acid mist is injected from the "rich liquid pot". Holes pop out, seriously polluting the production environment
