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
The present invention relates to the electrolyzer of a kind of cathode copper production method and production cathode copper.
Background technology
On cathode copper is produced, switch in the electrolytic solution of anode copper in electrolyzer " dissolving " gradually, go out to become cathode copper at the negative electrode wash rice.The electrolytic liquid level of PC all is a fixed in design, concerning the operator, can alleviate some labour intensity like this, but will produce following problem: because liquid level is fixed, the facial digit current density of catholyte is higher all the time, in electrolytic process, the electrolytic process at liquid level position is strengthened, and very easily forms negative electrode upper edge particle; The long-time electrolysis in cross section, anode upper edge forms the white crystals thing on the cross section, even still do not wash clean by washing; Anode dissolution only carries out on liquid level line, and the liquid level line position was very thin when other positions were also thicker, and very easily fracture is for the generation of avoiding rupturing can only be controlled higher residual anode ratio; The blocked up cathode copper that causes easily in cathode copper upper edge dehisces to come off at washing tank, and it is huge that the cathode copper that comes off shifts out the workload of washing tank.
Summary of the invention
The present invention solves in traditional electrolytic process exactly, and the negative electrode upper edge particle and the cross section, cathode copper upper edge that fixedly produce because of liquid level of electrolyte produce crystallisate, anode scrap easy fracture, the problem that cathode copper dehisces to come off at washing tank.
The technical solution used in the present invention is: a kind of cathode copper electrolysis process of changing electrolyte face is characterized in that may further comprise the steps:
(1), when switching on behind the electrolyzer tankage, liquid level is controlled at high liquid level energising electrolysis;
(2), energising is reduced to low liquid level with electrolyte level after four days and is continued electrolysis;
(3), copper the day before yesterday, electrolyte level is controlled at the electrolysis one day of switching on again of high liquid level;
(4), copper.
Adopt technique scheme, because in the electrolytic process, the liquid level of electrolytic solution appears at different positions, negative electrode is difficult for forming the upper edge particle; Cross section, negative electrode upper edge does not have long-time electrolysis, therefore can not produce too much white crystals thing, and anode scrap can not produce fracture; The cathode copper upper edge changes, and can not produce blocked uply, therefore can not produce at washing tank and dehisce to come off.
Realize the electrolyzer of the above-mentioned electrolysis process of right, it comprises cell body, cell body one end is provided with overflow port, the overflow port outlet is provided with overflow groove, the overflow groove bottom surface is provided with through hole, electrolytic solution is connected with return line by through hole, on described overflow groove, be provided with liquid level regulation device, it comprises outer layer sleeve, be sleeved on the inner layer sleeve that forms liquid sealing in the outer layer sleeve with outer layer sleeve, inner layer sleeve lower end and isopipe root through hole are suitable, upper side is provided with " V " v notch v, and outer layer sleeve is provided with the rectangle breach, realizes the liquid level lifting by the rotation outer layer sleeve with the area that overlaps of inner layer sleeve breach.
Adopt technique scheme, as long as it is, can regulate the height of electrolytic solution liquid level, therefore simple in structure, easy to use by the area that overlaps of rotation outer layer sleeve with the inner layer sleeve breach.
In sum, the invention has the beneficial effects as follows: adopt electrolysis process of the present invention, negative electrode is difficult for forming the upper edge particle, and cross section, negative electrode upper edge does not have long-time electrolysis, therefore can not produce too much white crystals thing, and anode scrap can not produce fracture; The cathode copper upper edge changes, and can not produce blocked uply, therefore can not produce at washing tank and dehisce to come off.Because electrolyzer of the present invention only need be realized the liquid level lifting with the area that overlaps of inner layer sleeve breach by the rotation outer layer sleeve, therefore regulates the electrolytic solution liquid level conveniently, and is simple in structure, is suitable for promoting the use of.
