Acid adding machine and acid adding system

Abstract

The invention discloses an acid adding machine which comprises an acid storage device capable of metering acid liquor, and a fixed displacement pump used for pumping in acid liquor, as well as a bottom acid tank and a first conduit, wherein the fixed displacement pump is connected with the acid storage device, the bottom acid tank is arranged at the lower part of the acid storage device, and the bottom acid tank is connected with the acid storage device through the first conduit. The invention further discloses an acid adding system. According to the acid adding machine, the bottom acid tank is arranged at the lower part of the acid storage device, and acid pumped by the fixed displacement pump is collected into the bottom acid tank after being added to a lead-acid storage battery, so as to be sent back to an acid cooling machine, so that the acid adding temperature each time can be ensured within in a range easy to fill acid, the quality of the battery is ensured, a series of problems that the acid overflowing of the battery causes corrosion of terminals, insufficient added acid or lack of added acid quantity and heating and deformation of the battery caused thereby, and the capacity of the battery is insufficient, and the like can be solved, the production efficiency is improved, the damage and scrape of the battery can also be reduced, and the production cost is lowered.

Description

technical field [0001] The application relates to the field of lead-acid storage battery manufacturing, in particular to an acid adding machine and an acid adding system. Background technique [0002] At present, in the manufacturing process of lead-acid batteries, the acid injection technology of the battery is mostly adopted. The ordinary acid injection technology is generally vacuumized by negative pressure and then acid injection. During the acid filling process, the temperature of the combined acid solution changes after the mixture of the remaining acid solution after the previous acid addition and the newly pumped acid solution in the acid cooler, so that after the acid is added to the battery, it will immediately react and produce A certain amount of gas will cause the acid liquid in the battery to overflow, which will easily cause problems such as terminal corrosion, failure to add acid or insufficient amount of acid, and it will also cause battery heating, expansio...

Problems solved by technology

During the acid filling process, the temperature of the combined acid solution changes after the mixture of the remaining acid solution after the previous acid addition and the newly pumped acid solution in the acid cooler, so that after the acid is added to the battery, it will immediately react and produce A certain amount of gas will cause the acid liquid in the battery to overflow, which will easily cause problems such as terminal corrosion, failure to add acid or insufficient amount of acid, and it will also cause battery heating, expansion and deformation, poor charging consistency, and insufficient capacity.
