Technical field
The present invention relates to non-ferrous metal field, and in particular to a kind of method of the multiple new cupric electrolysis contact rod of low cost.
Background technology
Contact rod primarily serves the effect of conduction during non-ferrous metal copper electrolyzing refining.All the time, there is coloured gold
The contact rod that category industry cupric electrolysis workshop uses after a certain period of use time, the defects of surface can crack, pit, has and split
Line, the contact rod of pit are easier by electrolytic corrosion, and electric conductivity is deteriorated, so annual cupric electrolysis industry has largely
Contact rod due to crackle, pit is serious and scraps processing, this causes the waste of resource to a certain extent.
Contact rod used in prior art is solid, is made using copper-clad iron process, cost of manufacture is higher, but this conduction
Rod intensity is big, is unlikely to deform, and can meet intensity requirement of the electrolysis production unit to contact rod.The service life of this contact rod is big
About at 6 years or so, need to remake after reaching Rejection standard, and somewhat expensive.
The reason of scrapping of cupric electrolysis contact rod is mainly the corrosion in production process, mainly there is following several situations：（1）Lead
Torch general corrosion, weight substantially mitigate, and weakened is yielding；（2）Contact rod surface corrosion is covered with fine cracks, conductive energy
Power dies down；（3）Contact rod local corrosion is present compared with deep crack, and serious exposes internal iron staff, and iron, which enters electrolyte, can cause electricity
Solve liquid pollution.
Cupric electrolysis workshop needs to buy new contact rod after contact rod is scrapped, and this undoubtedly adds the production of potroom
Cost, and the disadvantage that contact rod has the wasting of resources to a certain extent is scrapped, do not meet current potroom cost efficiency
Production requirement.
The content of the invention
It is an object of the invention to be solution the deficiencies in the prior art, and provide a kind of low cost multiple new cupric electrolysis contact rod
Method.
The new technical scheme of the present invention is：A kind of method of the multiple new cupric electrolysis contact rod of low cost, comprises the following steps：
A. boil to scrapping contact rod and wash processing, make clean in appearance no-sundries；
B. crack existing for scrapping contact rod surface is repaired, fine cracks are polished flat, and are smeared compared with deep crack with copper powder
It is flat；
C. ear is tied up with copper wire to scrapping contact rod, tripping in electrolytic cell makes contact rod be submerged after tying up ear in electrolyte, electricity as negative electrode
Solution a period of time；
D. the contact rod completed will be electrolysed to take out from electrolytic cell, after flushing and finishing, that is, obtain again it is new after contact rod.
Contact rod is scrapped in the step a in the water that temperature is more than 90 DEG C, boils and is washed till surface
Redgreen and other no dirts.
Contact rod is tied up ear requirement copper wire and tied up away from contact rod termination about at 10cm in the step c.
The current strength of direct current is 10000A-16500A in the step c, and current density is
170-290A/m2。
Bath composition is required in the step c（g/l）：Cu2+45-55；H2SO4165-185；
Ni<15；Fe<3；Cl-0.03-0.07。
The temperature of electrolyte is 62-63 DEG C in the step c.
Electrolysis time in the step c, according to current strength size, adjustable range 10-18h,
According to discarded contact rod weight, electrolysis time is suitably increased or decreased.
The material of contact rod is configured to copper-clad iron contact rod, and beam conduction rod average weight is 4.8kg, scraps contact rod and puts down
Equal weight is 4.3kg, and the contact rod average weight after answering newly is 5.1kg.
The beneficial effects of the invention are as follows：Innovative point of the present invention is to realize answering newly for cupric electrolysis contact rod, and advantage is to repair again
Contact rod intensity increase after multiple, conductive effect enhancing, Thinking Creation, methodological science are reasonable, and multiple new cost is low, efficiency high, real
Recycling for contact rod is showed, there is good economic benefit.
Brief description of the drawings
Fig. 1 is the process method flow chart of the present invention.
Fig. 2 is layout drawing of the multiple clean stub of the present invention in electrolytic cell.
Wherein：1 it is contact rod, 2 is that copper wire ties up ear.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
A kind of method of the multiple new cupric electrolysis contact rod of low cost, comprises the following steps：
A. boil to scrapping contact rod and wash processing, make clean in appearance no-sundries；
B. crack existing for scrapping contact rod surface is repaired, fine cracks are polished flat, and are smeared compared with deep crack with copper powder
It is flat；
C. ear 2 is tied up with copper wire to scrapping contact rod, tripping in electrolytic cell makes contact rod be submerged after tying up ear in electrolyte as negative electrode,
Electrolysis a period of time；
D. the contact rod 1 completed will be electrolysed to take out from electrolytic cell, after flushing and finishing, that is, obtain again it is new after contact rod 1.
Contact rod is scrapped in the step a in the water that temperature is more than 90 DEG C, boils and is washed till surface redgreen and without it
His dirt.
Contact rod is tied up ear requirement copper wire and tied up away from the termination of contact rod 1 about at 10cm in the step c.
The current strength of direct current is 10000A-16500A, current density 170-290A/m2 in the step c.

Average weight is 4.3kg, and the average weight of contact rod 1 after answering newly is 5.1kg.
Case study on implementation：
Contact rod is scrapped as new object is answered using copper electrolyzing refining workshop, implementation steps are as follows：
A, contact rod will be scrapped to be placed in the water that temperature is more than 90 DEG C, boils and be washed till surface redgreen and without other dirts；
B, repaired to scrapping corrosive shake existing for the surface of contact rod, to scrapping contact rod surface difference corrosion condition
Processing method, have following several：（1）Contact rod general corrosion, weight substantially mitigate, and surface crack is less, take measures be
Directly prepare electrolysis；（2）There is more corrosive shake in contact rod integral surface, take measures to be to prepare electricity after surface is polished flat
Solution；（3）Contact rod local corrosion exposes internal iron staff, it is with copper powder that the floating rear preparation in crack is electric to take measures compared with deep crack
Solution；
C, as shown in Fig. 2 to scrapping after contact rod ties up ear 2 with copper wire, tripping in electrolytic cell is electrolysed as negative electrode, and anode is copper
Positive plate.For ensure not influence to scrap contact rod it is new again after use, tie up ear status requirement away from scrapping conductive stick end about 10cm,
Contact rod is scrapped in each cathode site energy tripping in 10, and electrolyte will be submerged by scrapping contact rod, and Faradaic current size is 15000A,
It is electrolysed 16h；
D, the contact rod after the completion of electrolysis is taken out from electrolytic cell, the electrolyte on surface is rinsed out with water, to the long particle in surface
Contact rod repaired with sanding machine, that is, obtain again it is new after contact rod.
It is 4.3kg to scrap contact rod in new preceding average weight again, and multiple new rear average weight is 5.1kg, passes through electrolysis, reports
Useless contact rod surface adds one layer of copper, makes its surface smooth, and adds physical strength, enhances conductive effect,
The use standard of potroom production is reached.
After contact rod input Workshop Production use after answering newly, the using effect of beam conduction rod is reached, it was demonstrated that make
