Description

Technical Field

[0001] The utility model relates to the field related to copper foil, in particular to a device for recovering copper-containing flushing water of electrolytic copper foil. Background Art

[0002] The production process of copper foil substrate goes through the following processes in sequence: copper dissolving, filtration, additive addition, electroplating raw foil, and reflux to dissolve copper. The reflux process is because the raw materials overflowing after electroplating raw foil can be recycled, so it is necessary to return them to the copper dissolving pool for secondary circulation reaction.

[0003] And the material main component in the reflux process is a mixed solution of solid Cu, copper sulfate, and sulfuric acid, and the main purpose of this reflux is to return solid Cu and sulfuric acid to the copper dissolving pool for secondary reaction. Through the experience of the applicant, solid Cu has large particle state and small particle state in the mixed solution. Wherein, large particle solid Cu needs to be returned to the copper dissolving pool for secondary copper dissolving reaction, because the large particle solid Cu volume is large so the dissolution process is relatively slow, and the small particle solid Cu actually directly returns to the conveying channel after the copper dissolving and will be converted into free Cu2+ through the dissolution process of a shorter time. Therefore, the material is screened and processed, and the large particle solid Cu is separated and sent to the copper dissolving pool, and the small particle solid Cu is separated and directly sent to the conveying channel, which can more efficiently improve the yield.
