Problems solved by technology

Due to the large amount of acid used in the acid leaching process, the amount of waste liquid produced is also large. Therefore, direct discharge will inevitably pollute the environment, and the cost of waste liquid treatment is relatively high.

Abstract

The invention discloses an acid solution circulation apparatus. The apparatus comprises a solution storage tank and an acid pump, a settling chamber is formed in the solution storage tank by baffle plates, the solution storage tank is provided with a solution inlet and a solution outlet, the acid pump is provided with a solution inlet pipeline and a solution outlet pipeline, and one end of the solution inlet pipeline is connected with the solution outlet. The solution inlet of the invention can be used for collecting an acid solution which has solid impurities like a lead paste and the like, has a low acid content and is residual after acid spray, the solid impurities in the acid solution are removed by the settling chamber, a proper amount of a pasty acid is added to adjust the acid content, and the acid solution processed through above processes is pumped by the acid pump and can be continuously used for the acid spray. The apparatus can circulatorily use the acid solution and does not need discharge or neutralizing basically, so the resource waste is reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the field of accumulator manufacturing, in particular to an acid circulation device used for acid leaching the accumulator plate grid. Background technique [0002] Coating and leaching is an important process in battery manufacturing. Its main process is: use a coating machine to coat an appropriate amount of lead paste on the battery plate grid, and then transfer the plate grid coated with lead paste to the leaching acid The rack is poured with acid, and the sulfuric acid in the acid solution reacts with the lead plaster on the surface of the plates to form a lead sulfate protective film, thereby preventing cracks in the grid during the subsequent drying and curing processes, and avoiding the mutual adhesion between the plates. [0003] In the prior art, the waste liquid after leaching is usually directly discharged, or discharged after neutralization treatment. Due to the large amount of acid used in the acid leaching proce...
