Description

Etching solution regeneration and circulation device Technical Field The invention relates to the technical field of metal surface treatment and waste liquid circulation equipment, in particular to an etching liquid regeneration and circulation device. Background In the metal etching process, the etching solution can dissolve target metal on the workpiece, so that the concentration of metal ions in the etching solution is continuously increased, and solid particle impurities are generated in the etching process. These impurities and metal ions accumulate to reduce etching efficiency, affect processing quality, and eventually lead to failure of the etching solution. The traditional treatment mode is to transport and dispose the waste liquid, which not only has high cost, but also causes resource waste and environmental pollution. In the prior art, although equipment for recovering metals from etching waste liquid and regenerating etching liquid by an electrolysis mode is provided, the problems that firstly, the filtration of the etching waste liquid before electrolysis is insufficient or inconvenient, solid impurities easily enter an electrolysis area and adhere to the surface of an electrode to affect the electrolysis efficiency and even cause short circuit damage of the electrode, secondly, metals (such as copper, iron and the like) generated by electrolysis are deposited on the bottom of an electrolytic tank or the electrode in loose flocculent or powder form, the collection is difficult, the cleaning is complicated and the equipment is easy to block, and thirdly, the surface of the electrode is scaled or adhered with impurities after long-term use of the electrolyzer serving as a core part, and cleaning and maintenance are required, but the electrolyzer in the prior equipment is often fixed, the disassembly process is complicated and the periodic maintenance and the electrode replacement are inconvenient.
