Problems solved by technology
In the traditional sulfuric acid electrolyte preparation method, although the method is relatively simple, due to the interaction between concentrated sulfuric acid and deionized water, a large amount of heat will be released, and the acid concentration used in lead-acid batteries is relatively high. In view of the existing lead The method used in the acid dispensing process of acid battery production is mostly open, so the working environment of the acid dispensing workers is very bad, and sulfuric acid mist is diffused in the air, which will seriously affect the health of the production workers; at the same time, it is easy to cause environmental pollution Impurities and sundries fall into the acid tank and further affect the quality of battery products

Abstract
The invention discloses a lead-acid storage battery electrolyte preparation device which comprises a closed reactor and a membrane separator. The closed reactor is provided with a stirring device, a liquid inlet is formed in the top of the reactor, a liquid outlet is formed in the bottom of the reactor, and the membrane separator is capable of condensing acid mists and communicated with the reactor through an acid-resisting pipeline. Sulfuric acid solution can be effectively prevented from escaping due to a large number of acid mists generated by strong heat release in the preparation process, a production operation environment is remarkably improved, and the prepared sulfuric acid solution cannot be polluted by environmental impurities.
Description
technical field [0001] The invention relates to a liquid dispensing device, in particular to a device for preparing the electrolyte of a lead-acid storage battery. Background technique [0002] Lead-acid batteries are widely used in industrial production and people's daily life, accounting for about 70% of the total chemical power supply. Its manufacturing technology is mature, the process is relatively complete, the tooling is complete, and there are many types of products. It has formed a series of products and plays an important role in economic development. A great boost has been achieved. [0003] In the production of lead-acid batteries, the preparation of sulfuric acid electrolyte is an essential link. In the traditional sulfuric acid electrolyte preparation method, although the method is relatively simple, due to the interaction between concentrated sulfuric acid and deionized water, a large amount of heat will be released, and the acid concentration used in lead-ac...
