Description
Technical field
The invention belongs to technical field of smelting, and in particular to a kind of mixing electrolysis system for producing tough cathode.
Background technology
In the production of existing copper electrolyzing refining, be directly with blister copper as blister copper/residual electrode plate plate produces negative electrode refined copper.For
Whole electrolytic process negative electrode is set there are corresponding blister copper/residual electrode plate electrode wires, so blister copper/residual electrode plate plate can not be electrolysed completely
Utilize, so produce residual electrode plate.At present, residual electrode plate is only recycled by melting down double teeming, but it is high to melt down cost.According to system
Meter, a copper smelting plant for 400,000 tons of production capacity, more than 30,000,000 yuan, year treatment anode scrap amount exceedes the construction investment of novel residual anode processing operation
70000 tons, year anode scrap melt down cost more than 21,000,000 yuan.Each factory is the reduction residual electrode plate amount of melting down, typically by residual anode ratio control
13~20%, when residual anode ratio control is too low, can occur because of part blister copper/residual electrode plate plate plate face substance skewness, latter stage
It is broken, drop phenomenon, such one is that can cause electric pole short circuit, influences tough cathode quality, influence electricity effect；Two is that can smash electrolytic cell
Or the equipment such as unit；Three is negative electrode corresponding part without blister copper/residual electrode plate electrode wires, the negative electrode copper no longer long of the part.At present, OK
The above mentioned problem not occurred in use for blister copper/residual electrode plate plate also in the industry proposes more preferable improved method.
The content of the invention
Blister copper/anode scrap can be completely electrolysed it is an object of the invention to provide one kind, the production tough cathode of energy consumption is reduced
Mixing electrolysis system.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of mixing electrolysis system for producing tough cathode, including the electrolyte in electrolytic cell and electrolytic cell vallecular cavity, the electricity
Yin, yang busbar, the mixing electricity of the production tough cathode are equipped with the parallel two notch edge length direction for solving groove
Solution system also includes the negative electrode being arranged in parallel along electrolytic cell length direction and mixing electrolysis special anode, the negative electrode, mixing
Electrolysis special anode is electrically connected with yin, yang busbar respectively, inclined hanging with the plate of the mixing electrolysis special anode
It is provided with blister copper/residual electrode plate.
Above-mentioned technical proposal produce beneficial effect be：
Hung on mixing electrolysis special anode by by blister copper/residual electrode plate, can realize that blister copper/residual electrode plate is totally submerged
In the electrolytic solution.Blister copper/residual electrode plate that inclination hangs, changes the pole span of blister copper/residual electrode plate and negative electrode, makes blister copper/residual electrode plate
The orderly electrolysis completely gradually dissolved along direction from bottom to top, finally realize blister copper/residual electrode plate of energy, no longer produces residual
Pole.After blister copper/residual electrode plate has dissolved, the mixing electrolysis special anode may continue to conduction, for tough cathode provides electrode wires, because
This, the copper of blister copper/residual electrode plate dissolving can all be separated out in negative electrode, that is, realize the utilization completely of blister copper/residual electrode plate.The present invention is provided
Production tough cathode mixing electrolysis system for treatment blister copper/residual electrode plate blister copper/recovery anode scrap provide simple and easy to do, low cost
Honest and clean new method, can eliminate residual electrode plate and melt down operation, shorten Copper making technological process, and the items that residual electrode plate melts down can be saved again
Significant cost and great number energy consumption, can be significantly enterprise's cost efficiency.
