Abstract

The invention relates to the field of lead battery manufacturing, in particular to a battery lead paste mixing device and a paste mixing process using the device. The device is a pre-mixing device before mixing paste, which includes a tank body, and a mixer feed port and a water inlet are arranged on the tank body, and the uniformity of the lead paste is further improved by pre-mixing each component of the raw material of the lead paste.

Description

technical field [0001] The invention relates to the field of lead battery manufacturing, in particular to a battery lead paste mixing device and a paste mixing process using the device. Background technique [0002] Lead paste is the matrix of the active material of the pole plate. It is a paste-like substance with certain plasticity formed by mechanical stirring and mixing of lead powder with a certain degree of oxidation and apparent density, water and sulfuric acid solution. The role of lead paste in lead-acid batteries is mainly to provide and store the substances required for electrochemical reactions. Lead paste is a plastic substance mixed with lead powder, water, sulfuric acid and additives. Its properties are mainly manifested in the apparent density and consistency of lead paste. Therefore, the prepared lead paste should have good plasticity, so that the lead paste can be easily bonded to the grid when coating the board, and can be evenly coated and filled with th...
