Problems solved by technology

For the former method, it directly causes the waste of materials, increases the battery cost, and greatly increases the sewage pressure of the enterprise; for the latter method, because the lead sludge contains a large amount of lead sulfate, and the content is unstable , if it is directly recycled, it will have a significant impact on the processing of lead-acid batteries, and greatly affect the performance consistency and service life of lead-acid batteries

Embodiment Construction

[0019] A method for recovering residual paste by boiling water and boiling acid on a lead-acid battery smear, specifically, it can be realized through the following steps:

[0020] (1) Put the lead paste into the smearing equipment through the lead bucket, use the smearing equipment to apply the lead paste evenly on the lead grid according to a certain weight, and pass the coated lead grid through the first pressing roller, The fluffy lead paste on the surface of the lead grid is compressed evenly and evenly, and the excess lead paste is squeezed out of the lead grid (such as being squeezed to both sides of the lead grid);

[0021] (2) Perform boiling water operation on the lead grid, that is, roll the water evenly on the surface of the lead grid, and under the action of the water flow, wash the extruded lead paste and the loose lead paste on the surface of the lead grid, The lead paste washed out by the above-mentioned boiling water is collected together with the water flow; ...

Abstract

The invention relates to a method for recycling residual paste from a lead-acid storage battery smear through water rolling and acid rolling. The method mainly comprises the following steps of: coating lead paste on a lead grid, subsequently performing first roller extrusion on the lead grid so as to compress and flatten the loose lead paste on the surface of the lead grid, and simultaneously extruding the redundant lead paste; performing water rolling operation on the lead grid, washing and collecting the extruded residual lead paste through water flow action, further extruding the lead grid and performing acid rolling operation, and separately recycling the extruded residual lead paste at the same time. Due to adoption of the steps, the residual paste generated in the lead-acid storage battery machining and production process can be effectively recycled, and meanwhile the consistency of the lead-acid storage battery is sufficiently ensured, and moreover the circulation service life of the lead-acid storage battery is greatly prolonged.

Description

technical field [0001] The invention relates to a method for recovering excess paste from lead-acid battery smears by boiling water and acid. Background technique [0002] During the processing of lead-acid batteries, after smearing the plates of lead-acid batteries, the surface must be flattened first, and then the acid rolling process is carried out, thus producing about 3%-5% of extruded lead slime , that is, Yu Gao. At present, there are mainly two ways to deal with excess paste in this industry: one is to treat it as waste, and the other is to directly recycle it. For the former method, it directly causes the waste of materials, increases the battery cost, and greatly increases the sewage pressure of the enterprise; for the latter method, because the lead sludge contains a large amount of lead sulfate, and the content is unstable , if it is directly recycled, it will have a significant impact on the processing of the lead-acid battery, and greatly affect the performan...
