Cooling device of lead plate roller

Abstract

The invention relates to a cooling device of a lead plate roller. The cooling device comprises a roller with the internal as a tubular cavity structure; multiple semiconductor refrigeration chips are uniformly distributed on the inner surface of the tubular cavity of the roller; refrigeration surfaces of the semiconductor refrigeration chips are tightly bonded with the inner surface of the tubular cavity of the roller; two electrodes of multiple conductor refrigeration chips are at least connected with one ends of two spring copper pieces through lead holes formed in a shaft head after parallel connection; electric brushes are arranged at the other ends of the at least two spring copper pieces, and are electrically connected with at least two annular groove electrodes in a bearing base; and electrode wiring terminals are arranged between the at least two annular groove electrodes and the outer surface of the bearing base. The cooling device of the lead plate roller has such characteristics as relatively simple structure, high cooling efficiency, stable roller operation and safe and reliable use.

Description

technical field [0001] The invention relates to the technical field of grid processing equipment for lead-acid batteries, in particular to a cooling device for lead plate rolls. Background technique [0002] The main function of the grid in the lead-acid battery is to conduct and collect the current, and to make the current distribution even, and on the other hand, to support the active material. The grid is not only a conductive skeleton, but also an active material carrier with dual functions. Therefore, the grid must have certain mechanical, electrical, and metallurgical characteristics. That is to say, the grid is required to have good mechanical properties (including hardness, tensile strength, castability, weldability), good corrosion resistance and good electrical conductivity. [0003] At present, the main methods of making lead-acid battery grids include stretching, continuous casting and rolling, gravity casting and forging strip expansion, casting expansion, sta...

AI Technical Summary

Problems solved by technology

Due to the natural sagging of the lead plate and the process of bending and transmission, one side of the lead plate is subjected to compressive stress and the other side is subjected to tensile stress, which will cause the plate surface to bend, and the processed grid will also appear warped. the amount of questions
