Technical Field

The invention relates to the technical field of electrolytic smelting, in particular to a copper electrolysis cathode washing stripping process and a cathode washing stripping unit thereof.

Background

In a traditional cathode washing and stripping unit, a cathode plate attached with cathode copper is firstly washed, then the cathode copper with the mutually adhered bottoms is taken down through a receiving mechanism below the cathode plate when the cathode copper on two sides of the cathode plate is stripped from the cathode plate, two adhered cathode copper are taken down to be put into a finished product conveying chain, two smooth surfaces are mutually attached, and then the cathode copper is conveyed to the finished product conveying chain in the state to be packaged.

The traditional unit can only wash away electrolyte and anode mud attached to the outer side of cathode copper because the washing operation is completed before the cathode copper is stripped, however, the electrolyte and the anode mud are also attached to the inner side of the cathode copper under the following conditions: on the one hand, the negative plate is in the transfer process or in the electrolytic deposition process, the edge clamping strips (preventing that the cathode copper sides on the two sides are connected together and are difficult to strip) arranged on the two sides of the negative plate are loosened, the edge clamping strips and the negative plate sides generate gaps, electrolyte or anode mud can be retained in the gaps, when the cathode copper is stripped in a stripping system, the retained electrolyte or anode mud enters the gaps between the negative plate and the cathode copper and is attached to the inner side surface of the cathode copper and is always retained. On the other hand, in the transportation process of the cathode plate with the cathode copper attached, the cathode copper and the cathode plate have certain probability of opening (the cathode copper is separated from the cathode plate at the upper part) in the process of taking out the tank and before washing, and the electrolyte and the anode mud which are supposed to flow away along with the washing flow enter the inner side of the cathode copper from the opening position and are left in the washing process. Because the cathode copper is a commodity which can be marketed, the market has strict index requirements on the chemical composition of the cathode copper, if the electrolyte and the anode mud are excessive, the chemical composition of the cathode copper cannot meet the requirements, and the cathode copper produced in a factory is rejected or sold at a reduced price. Meanwhile, the anode slime is a valuable raw material containing a large amount of precious metals, and the low recovery rate affects the income of a factory.
