Description
Technical field
The utility model relates to non-ferrous metal electrodeposition insoluble anode technical field of structures in a kind of hydrometallurgy.
Background technology
In whole industrial production, metallurgical industry remains big power consumer, and production energy consumption is high, and in the smelting process of non-ferrous metal, the zinc of about more than 90% and the copper of about 30% are extracted by hydrometallurgical technology.Especially, in Zinc Hydrometallurgy Process, electrodeposition operation consumes the energy consumption of whole zinc leaching process 2/3.And in non-ferrous metal (zinc, copper, manganese, nickel etc.) electrodeposition leaching process, anode material character directly affect ionic discharge current potential, the change of overpotential, current efficiency size, power consumption, anode life and cathode product quality etc. index.
The insoluble anode of current use is lead based alloy anodes, lead based alloy anodes low price, stable performance, but lead based alloy anodes in use exists, and overpotential for oxygen evolution is high, energy consumption is large, quality is heavy, operation is inconvenient, yielding, facial pallor is easily separated out at negative electrode and is polluted cathode product, and electrolytic solution needs the shortcomings such as regular deleading.
The preparation of the inertia anode of lead dioxide of prior art, selects titanium, graphite, plastics and pottery etc. to be body material, by matrix surface roughening treatment, coating bottom, α-PbO usually
2middle layer and plating β-PbO
2etc. primary process, be coated with and obtain PbO
2electrode.Its advantage can operate at higher current densities for (1); (2) generation of mud can be suppressed; (3) oxidation efficiency can be improved; (4) good solidity to corrosion and long lifetime; (5) in Zinc electrolysis, need not carry out changing into process, and the amount that lead is mixed in zinc reduces, good to the solidity to corrosion of chlorine, and chlorine can be removed (experiment proof, electrolytic solution is chloride more than 1000mg/L, and chlorion will corrode anode, and anode is oxidized to oxymuriate, pole plate is thinning, perforation, life-span shortens greatly), can not produce manganese slag, the current efficiency extracting zinc is high.But the PbO that plating is obtained like this
2electrode, as insoluble anode, in use there will be following problem: (1) PbO
2settled layer is combined not tight with electrode surface or settled layer is uneven; (2) PbO
2settled layer porous and coarse, internal stress is large; (3) PbO
2settled layer easily peels off or corrodes, and the life-span is not long.
Summary of the invention
The purpose of this utility model is the shortcoming of the existence in order to overcome above-mentioned prior art, provides that a kind of electro catalytic activity is good, the non-ferrous metal electrodeposition graded composite anode that bath voltage is low, long service life, energy consumption are low in electrodeposition.
The purpose of this utility model is achieved through the following technical solutions:
A kind of non-ferrous metal electrodeposition graded composite anode, erect excellent Connecting groups by one group of titanium rod sidewards with three titanium copper-clads and dress up palisading type titanium board substrate, the titanium copper-clad conducting beam of palisading type titanium board substrate and top is welded to form electrode materials.
