Embodiment Construction
[0017] Specific implementation plan
[0018] Such as figure 1 with figure 2 As shown, a battery waste acid recycling device includes:
[0019] The sedimentation tank 14 is used to collect and store the waste acid generated in the production process of the battery and precipitate the sundries in the waste acid. The sedimentation tank is located at the lower ends of the first and second filter boxes on the bracket 13. The liquid inlet of the pump tube 15 of the liquid suction pump 17 communicates with the middle of the sedimentation tank, and the liquid outlet of the pump tube of the liquid suction pump communicates with the acid collection tank 1 at the upper end of the first filter tank.
[0020] The bracket 13 is used to support the first, second, and third filter boxes and the acid collection box, the bracket is in a stepped shape, and the first, second, and third filter boxes and the acid collection box are located in order from high to low On each step of the bracket.

Abstract
The invention belongs to a battery waste acid recycling device which comprises a sediment box, a bracket, a first filtering box body, a second filtering box body, a third filtering box body and an acid liquor collection box, wherein the first filtering box body is used for performing primary filtering waste acid precipitated in the sediment box for a first time; the first filtering box is arranged on the top end of a ladder layer of the bracket; the first filtering box body is internally provided with a tapered filter; a box body arranged at the lower end of the tapered filter is communicated with an acid collection tank arranged at the upper end of the second filtering box body by virtue of a liquid outlet valve; a filter screen cover is arranged at the upper end of the tapered filter; the acid collection tank is arranged at the upper end of the filter screen cover; the upper part of the acid collection tank is provided with an overflow pipe communicated with the upper end of the sediment box; and the particles filtered by the tapered filter of the first filtering box body have the diameters of 30-40mu m. The battery waste acid recycling device is low in cost and less in energy consumption, can be used for recycling the battery waste acid in a way of in-situ, and effectively solving the problem that the environment is polluted by the battery waste acid; and furthermore, the battery waste acid recycling device has the advantages of being simple in structure, low in purification cost and good in purification effect, enabling the filtered sulfuric acid to be used again, protecting the environment, saving energy and recycling the waste.
Description
[0001] Technical field [0002] The invention belongs to a battery waste acid recycling device. Background technique [0003] The main ways to produce waste sulfuric acid (abbreviated as waste acid) in the production process of lead-acid batteries are the waste acid produced by acid leaching during the coating process and the waste acid produced during the battery charging process. About 10%, the concentration of waste acid generated during battery charging is about 35%. The impurities in the waste acid are mainly lead powder. Because the acid content in the waste acid is relatively high and contains lead powder, it will be discharged even if it is directly neutralized. Polluting the environment, direct neutralization will waste a lot of hydrochloric acid and alkali, and the processing cost is high, which cannot meet the requirements of energy saving and emission reduction of enterprises. At present, most domestic companies that produce waste sulfuric acid from batteries do not...
