Cathode copper electrolytic method for changing electrolyte level and electrolytic cell

Abstract

The invention relates to a cathode copper electrolytic method for changing electrolyte level and an electrolytic cell. The cathode copper electrolytic method and the electrolytic cell solve problems that the prior electrolyte level is fixed so as to generate the crystal substance on a cathode along particles and on cathode copper along a section, a residual anode is easily broken and the cathode copper drops off at an opening of a washing box. The technical scheme of the invention is to change upper level of the electrolytic level in the electrolytic process so as to effectively solve the problems. An overflow trough of the electrolytic cell realizing the change of the electrolyte level is provided with a level regulation device. The electrolytic cell comprises an external sleeve (4) and an internal sleeve (3) which is sleeved in the external sleeve (4) and forms liquid seal with the external sleeve. A lower end of the internal sleeve (3) is fit with a through hole on a bottom part ofthe overflow trough. A lateral surface on an upper end of the internal sleeve (3) is provided with a V-shaped notch (6). The external sleeve (4) is provided with a rectangle notch (7). Electrolyte level fluctuation is realized through rotating a coincidence area of the external sleeve and the internal sleeve. The cathode copper electrolytic method and the electrolytic cell of the invention can conveniently regulate the electrolyte level.

Description

technical field [0001] The invention relates to a cathode copper production method and an electrolytic cell for producing cathode copper. Background technique [0002] In the production of cathode copper, the anode copper is gradually "dissolved" in the electrolyte in the electrolytic cell, and is drawn out at the cathode to become cathode copper. In the design, the liquid level of PC electrolysis is fixed, which can reduce some labor intensity for the operator, but it will cause the following problems: due to the fixed liquid level, the current density at the cathodic liquid level is always high. During the process, the electrolysis process at the liquid surface is strengthened, and it is easy to form particles along the upper edge of the cathode; the upper edge of the anode is electrolyzed for a long time, and white crystals are formed on the cross section, which cannot be cleaned even after washing; the anode dissolves only on the liquid level line When the other parts a...

Problems solved by technology

[0003] The present invention is to solve the problem that in the traditional electrolysis process, the particles on the upper edge of the cathode and the cross-section of the upper edge of the cathode copper produce crystals due to the fixed liquid level of the electrolyte, the remnants are easily broken, and the cathode copper falls off at the opening of the washing box.
