Copper electrolysis cathode washing and stripping process and cathode washing and stripping unit thereof

Abstract

The invention belongs to the technical field of electrolytic smelting, and discloses a copper electrolysis cathode washing and stripping process and a cathode washing and stripping unit thereof. The process comprises the following steps of S1, carrying out first-time washing on a cathode plate attached with cathode copper through plate pushing and distance expanding; S2, feeding the cathode plateattached with the cathode copper and obtained after the first-time washing into a stripping system for stripping of the cathode copper; S3, flatly laying two pieces of mutually-connected cathode copper which are stripped from the surfaces of the two sides of the cathode plate; S4, tearing and separating the two pieces of mutually-connected cathode copper; S5, removing the cathode copper from the torn part, and carrying out second-time washing on the smooth face of the cathode copper; and S6, transferring the cathode copper obtained after the second-time washing to a conveying chain, and transferring the qualified cathode copper to a packaging chain by the conveying chain for packaging. According to the copper electrolysis cathode washing and stripping process and the cathode washing and stripping unit thereof, the two pieces of cathode copper on the two sides of the cathode plate are creatively turned, torn and separated during stripping, the situation that the smooth face of the cathode copper cannot be exposed to the outside due to continuous adhesion of the two pieces of cathode copper is avoided, and then the cathode copper with the smooth face facing upwards undergoes second-time washing, and then impurities on the smooth face of the cathode copper can be removed to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of electrolytic smelting, in particular to a cathode washing and stripping process of copper electrolysis and a cathode washing and stripping unit thereof. Background technique [0002] In the traditional cathode washing and stripping unit, the cathode plate with cathode copper is first washed, and then the cathode copper on both sides of the cathode plate is peeled off from the cathode plate through a receiving mechanism under the cathode plate to remove the cathode copper adhered to each other at the bottom , During the process of removing the bonded two pieces of cathode copper and putting them into the finished product conveyor chain, the two smooth surfaces will stick to each other, and then the cathode copper is transported to the finished product conveyor chain in this state for packaging. [0003] Because the washing operation of the traditional unit is completed before the cathode copper is stripped...

AI Technical Summary

Problems solved by technology

Since cathode copper is a commodity that can be traded on the market, the market has strict requirements on the chemical composition of cathode copper. If there is too much electrolyte and anode slime, the chemical composition of cathode copper will not meet the requirements, and the cathode copper produced by the factory will be reduced. Rejected, or sold at a reduced price

At the same time, anode slime is a valuable raw material containing a large amount of precious metals, and the low recovery rate will affect the profit of the factory
