Embodiment 1

[0025] Such as figure 1 , 2Shown in , 4, a kind of device for reducing acid-leaching lead mud, comprises polar plate 6, end-to-end connection and the acid-leaching cloth 7 of opening at both ends and the acid-leaching pipe 1 that the interior is filled with sulfuric acid solution, and the acid-leaching cloth 7 is installed on the acid-leaching cloth On the pipe 1, the acid-drenched cloth 7 is made of acid-resistant polyester staple fiber, the acid-drenched cloth 7 is a multi-layer fine-grained non-woven fabric, and the surface of the cloth is a mesh structure, and the mesh structure on the surface of the acid-washed cloth 7 can be reversed. The acid drenched with acid is filtered again, and the length of the acid drenched cloth 7 is slightly greater than the length of the pole plate 6 joint plates, which can ensure that every position on the surface of the pole plate 6 can be drenched with acid, and the lower part of the acid drenched cloth 7 is parallel to and kept A certain...

Abstract

The invention relates to the technical field of lead-acid battery production, and in particular relates to a device for reducing lead leaching mud. The device for reducing lead leaching mud comprisesan electrode plate and leaching cloth connected end to end, wherein openings are arranged in both ends. The device further comprises a leaching pipe filled with a sulfuric acid solution. The leachingcloth is arranged on the leaching pipe. A valve is arranged on the leaching pipe. A plurality of leaching holes corresponding to the leaching cloth are arranged in the leaching pipe. A gap is formed between the bottom end of the leaching cloth and the electrode plate. According to the invention, the amount of lead mud generated during the electrode plate coating process is reduced.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery production, in particular to a device for reducing acid-leaching lead mud. Background technique [0002] As the lead-acid battery market becomes more and more saturated, major lead-acid battery manufacturers will conduct a battery price war in order to expand their market share. In the case of constant battery quality, controlling battery manufacturing costs has become an urgent task for the lead-acid battery industry. [0003] During the production process of the plate, the grid is covered with lead paste, which has poor strength and is not convenient for subsequent operations. A dense lead sulfate protective layer is formed by spraying sulfuric acid evenly on the surface of the plate. On the one hand, lead sulfate is not sticky, and the plate passes through After fast drying, the raw plate will not stick to the plate when it is collected and put on the curing rack; on the other hand, ...
