Description

Technical Field

[0001] The utility model belongs to the technical field of lead paste preparation, in particular to a lead paste stirring mechanism for a battery. Background Art

[0002] Lead paste is a paste made by mixing lead powder, water, acid and additives in a paste machine. The lead paste needs to be stirred in a stirring device to make it evenly mixed with the auxiliary materials. The preparation of lead paste has always been an important, complex and difficult-to-control production process in the production of lead-acid battery plates. The acid content of the lead paste is also directly related to the battery capacity. The concentration of lead paste is relatively high, so it is relatively viscous. During the production process, it needs to be stirred with a special mixing paste machine to achieve even mixing of the lead paste components, thereby ensuring the quality of the final product lead-acid battery.

[0003] At present, when a paste mixing machine is mixing lead paste, due to the huge amount of one-time mixing, during the mixing process, if the mixing resistance is small, the paste flow rate is low; if the mixing resistance is too large, the equipment operation load is large, the mixing blades are easily deformed and damaged due to the large force, and the rotation rate is relatively reduced, which will also reduce the mixing effect; it makes it difficult to fully mix the lead paste and the mixing efficiency is low, thereby affecting the quality of lead paste manufacturing, and there is a disadvantage that the mixing resistance and the stirring effect cannot be effectively adjusted; therefore, the utility model designs a lead paste mixing mechanism for batteries.
