Description

Technical Field

[0001] The utility model mainly relates to the technical field of copper foil processing, in particular to a water receiving device for washing the surface of electrolytic raw foil. Background Art

[0002] Foil manufacturing is a key process in electrolytic copper production. Raw foil is a semi-finished product of finished electrolytic copper, which determines most of the quality and performance of electrolytic copper foil. After the copper foil comes out of the anode tank and is formed on the cathode roller surface, the foil surface will carry fine copper powder. Therefore, it needs to go through acid washing / acid squeezing and water washing / water squeezing processes before peeling. The water after washing contains a large amount of copper powder particles and other impurities, which will cause electrolyte contamination and excessive impurity content. Excessive impurity content in the electrolyte will cause pinholes on the surface of the copper foil, which will seriously affect the quality of the copper foil and cause a large amount of scrap.

[0003] Although the squeezing and washing devices of existing foil machines can meet the requirements of producing ordinary copper foil, when producing extremely thin, high-performance lithium battery copper foil, it is difficult to clean the wastewater on the foil surface by relying solely on the squeezing roller, which can easily cause contamination of the electrolyte. However, if the impurity content of the electrolyte exceeds the standard, the qualified rate of the copper foil and production efficiency will decrease. Utility Model Content
