Description
Technical field
The invention belongs to technical field of smelting, and in particular to a kind of mixing electrolysis system producing tough cathode.
Background technology
It is directly to produce cathode refined copper using blister copper as blister copper/residual electrode plate plate in existing copper electrolyzing refining production.For
Entire electrolytic process cathode is set there are corresponding blister copper/residual electrode plate electrode wires, so blister copper/residual electrode plate plate cannot be electrolysed completely
It utilizes, so generate residual electrode plate.Currently, residual electrode plate is only recycled by melting down double teeming, but it is high to melt down cost.According to system
Meter, the copper smelting plant of 400,000 tons of a production capacity, novel residual anode processing process construction investment is more than 30,000,000 yuan, and year processing anode scrap amount is more than
70000 tons, year anode scrap to melt down cost be more than 21,000,000 yuan.Each factory is to reduce the residual electrode plate amount of melting down, and generally controls residual anode ratio
13~20%, when residual anode ratio control is too low, can be unevenly distributed because of part blister copper/residual electrode plate plate plate face substance, latter stage occurs
It is broken, falls phenomenon, such one is that can cause electric pole short circuit, influences tough cathode quality, influences electric effect；Second is that electrolytic cell can be smashed
Or the equipment such as unit；Third, cathode corresponding part is without blister copper/residual electrode plate electrode wires, the no longer long copper of cathode of the part.Currently, row
There are no the above problems occurred in use for blister copper/residual electrode plate plate to propose better improved method in the industry.
Invention content
The purpose of the present invention is to provide one kind being electrolysed blister copper/anode scrap completely, reduces the production tough cathode of energy consumption
Mix electrolysis system.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of mixing electrolysis system producing tough cathode, includes the electrolyte of electrolytic cell and electrolytic bath intracavitary, the electricity
It solves and is equipped with yin, yang busbar on two parallel notch edge length directions of slot, the mixing electricity of the production tough cathode
Solution system further includes the cathode being arranged in parallel along electrolytic cell length direction and mixing electrolysis special anode, the cathode, mixing
Electrolysis special anode is electrically connected with yin, yang busbar respectively, inclined hanging with the plate of the mixing electrolysis special anode
Equipped with blister copper/residual electrode plate.
The advantageous effect that above-mentioned technical proposal generates is：
By hanging over blister copper/residual electrode plate on mixing electrolysis special anode, it can realize that blister copper/residual electrode plate is totally submerged
In the electrolytic solution.Blister copper/the residual electrode plate hung is tilted, the pole span of blister copper/residual electrode plate and cathode is changed, makes blister copper/residual electrode plate
It orderly can gradually be dissolved along direction from bottom to top, finally realize the complete electrolysis of blister copper/residual electrode plate, no longer generate residual
Pole.After blister copper/residual electrode plate has dissolved, which may continue to conduction, and electrode wires are provided for tough cathode, because
This, the copper of blister copper/residual electrode plate dissolving can all be precipitated in cathode, that is, realize the full utilization of blister copper/residual electrode plate.The present invention provides
Production tough cathode mixing electrolysis system for processing blister copper/residual electrode plate blister copper/recycling anode scrap provide it is simple and easy to do, at low cost
Honest and clean new method can eliminate residual electrode plate and melt down process, shorten Copper making technological process, and can save the items that residual electrode plate melts down
Significant cost and great number energy consumption can be significantly enterprise's cost efficiency.
