Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery production, and in particular relates to a liquid distributor and a paste mixing device. Background Art

[0002] During the research and development of new formulas for lead-acid batteries, the formula needs to be tested on a paste mixing machine to verify the feasibility of the formula. The paste mixing machines on existing lead-acid battery production lines are often large in volume, and about one ton of raw materials need to be put into the paste mixing machines for mixing each time. Directly using the paste mixing machines on the lead-acid battery production line to test the formula can easily lead to a large amount of raw materials. In addition, during the mixing process, the existing paste mixing machines have poor dispersion effects when adding water, which can easily lead to uneven mixing of the various components in the formula, affecting the quality of the paste.

[0003] To this end, technical personnel in this field urgently need to develop a small-scale paste-mixing device suitable for mixing a small amount of raw materials and specially used for testing new formulas of lead-acid batteries. At the same time, there is also an urgent need to develop a liquid distributor that can be used on a paste-mixing machine to improve the dispersion effect when adding water, ensure the full mixing of the raw materials in the formula, and thereby improve the quality of the paste.
