Description

Technical Field

[0002] To reduce the loss of precious metals caused by the Burts process in lead refining and to achieve higher purity in electrolytic lead, researchers have proposed a lead-acid battery electrolyte refining process, which uses lead-acid battery electrolyte electrolytic refining to obtain lead. During lead refining, anode slime forms at the bottom of the electrolytic cell, requiring filtration to obtain a higher-purity electrolyte. An existing patent (Announcement No.: CN212881427U) discloses a lead-acid battery electrolyte filtration device. This utility model first agitates the recycled electrolyte from lead-acid batteries to initially separate impurities from the liquid, then uses filter plates to filter the electrolyte again, effectively improving electrolyte processing efficiency. However, in practice, the filter plates filter out impurities from the electrolyte, causing them to accumulate between adjacent filter plates, making them difficult to clean. To address this issue, we have proposed a device for filtering anode slime from the bottom of a lead electrolytic refining cell. Utility Model Content
