Description

Technical Field

[0001] The utility model relates to the technical field of lead paste desulfurization equipment, in particular to a lead paste desulfurization device. Background Art

[0002] Lead-acid battery is a common storage battery, which uses sulfuric acid solution as electrolyte and has strong overall sealing. During long-term use, as discharge and charging proceed, lead paste is formed in the lead-acid battery. The lead paste is mainly composed of PbSO4. During the recycling process, sulfur oxides are formed in the solution under high temperature conditions, which are highly polluting and affect the environmental friendliness of the processing. Therefore, desulfurization equipment is needed to pre-treat the lead paste to reduce the sulfur content in the lead paste.

[0003] In the desulfurization process, a desulfurizer and lead sulfate are usually mixed and stirred. The desulfurizer and lead sulfate are fully reacted by stirring to break the encapsulation effect of the lead sulfate.

However, due to the difference in density of desulfurizers, lead sulfate and other substances, when the desulfurizer and lead sulfate are mixed, the desulfurizer and lead sulfate have a partial layer phenomenon, and the conventional stirring blades are used for directional stirring, which cannot effectively mix the desulfurizer and lead sulfate, and the mixing efficiency is low and the desulfurization speed is slow. Therefore, in order to solve the problems existing in the prior art, this application is specially proposed to solve them. Utility Model Content
