Embodiment 1

[0025] like figure 1 , 2As shown in , 4, a device for reducing acid leaching lead mud comprises polar plate 6, acid leaching cloth 7 connected end to end and open at both ends and acid leaching pipe 1 filled with sulfuric acid solution inside, and acid leaching cloth 7 is installed in the acid leaching cloth 7. On the pipe 1, the acid-spraying cloth 7 is made of acid-resistant polyester staple fibers. The acid-spraying cloth 7 is a multi-layer fine-grained non-woven fabric. The surface of the cloth is a mesh structure. The acid leaching used is filtered again, the length of the acid leaching cloth 7 is slightly larger than the length of the plate 6, which can ensure that every position on the surface of the electrode plate 6 can be leached with acid, and the lower part of the acid leaching cloth 7 is parallel to the plate surface of the electrode plate 6 and keeps A certain distance can ensure that each position of the electrode plate 6 is evenly sprayed with acid. The inner ...

Abstract

The invention relates to the technical field of lead-acid battery production, in particular to a device for reducing acid-leaching lead mud. A device for reducing acid-leaching lead mud, comprising pole plates, end-to-end acid-leaching cloths with openings at both ends, and acid-leaching pipes filled with sulfuric acid solution inside, the acid-leaching cloths are installed on the acid-leaching pipes, and the A valve is arranged on the acid shower pipe, and a plurality of acid shower holes are arranged on the acid shower pipe corresponding to the acid shower cloth, and there is a gap between the bottom end of the acid shower cloth and the pole plate. The invention can reduce the amount of lead sludge produced in the plate coating process.

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 and lead mud. Background technique [0002] With the increasing saturation of the lead-acid battery market, major lead-acid battery manufacturers will engage in battery price wars in order to expand their market share. Under the condition of constant battery quality, controlling the battery manufacturing cost has become an urgent task for the lead-acid battery industry. [0003] During the production process of the electrode plate, the grid is coated with lead paste and the strength is poor, which is inconvenient for subsequent operations. A dense lead sulfate protective layer is formed by uniformly spraying sulfuric acid on the surface of the electrode plate. On the one hand, lead sulfate is not sticky, and the electrode plate passes After rapid drying, the green plate does not stick to the plate when it is collected and ...
