[0002] Copper dissolution is the first step in the production of electrolytic copper foil and is a very important process. Whether copper dissolution operates normally and stably is directly related to whether the production of electrolytic copper foil can proceed smoothly and whether the quality of electrolytic copper foil is stable. Both fresh copper dissolved by copper dissolution and the solution returned from the electrolytic process may be contaminated by other impurities. In order to avoid the harm of impurities to the electrolytic process, they are removed through the purification process before entering the electrolytic cell again. Adding activated carbon and diatomaceous earth to the electrolyte can improve the purity of the electrolyte and thus improve the quality of electrolytic copper foil products. At present, activated carbon and diatomaceous earth are usually added to the waste liquid tank at a rate of 80 to 120 g / h by operators manually. This manual operation method has problems such as high labor intensity, inaccurate control of the amount of addition, and inaccurate addition time, thereby weakening the effect of improving product quality by adding activated carbon and diatomaceous earth. In addition, improper operation will seriously affect the stability of the copper dissolution process, thereby causing the quality of electrolytic copper foil products. Utility Model Content
