Description
Technical field
The invention belongs to electrolysis tech fields, and in particular to a kind of non-melting electrolysis process process of copper scap compression moulding.
Background technique
The method for recycling copper scap both at home and abroad at present is broadly divided into two major classes, first is that the copper scap by high quality is direct
Smelt into purpurine copper or copper alloy；Second is that by copper scap smelt at after anode plate through electrorefining at cathode copper.Method is will be miscellaneous
Blast furnace is added in copper or converter is smelted into blister copper, and anode furnace is added again and is smelted into after anode plate again electrorefining into electrolysis for blister copper
Copper.The disadvantage is that the flue dust of output is difficult to handle when processing copper scap, while the furnace duration of refining operation, and large labor intensity, production
Rate is low, and metal recovery rate is low.
Summary of the invention
The purpose of the present invention is to provide a kind of non-melting electrolysis process processes of copper scap compression moulding, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the goals above, the present invention is to realize by the following technical solutions: a kind of copper scap compression moulding
Non- melting electrolysis process process, process flow are as follows:
(1) copper scap is broken: copper scap being made a gift to someone in crusher by belt conveyor, by Mechanical Crushing, composition brass is broken into
1-5 millimeters long of copper rice, copper rice separate iron by magnetic field, separate using vibration, plastics are separated with copper rice, obtain cupric
Pure copper rice greater than 98%.
(2) copper enameled wire depainting: enameled wire is added in ball mill, after being crushed and copper rice is made using between steel ball
Extruding repeatedly is hit, and the insulated paint that copper rice surface is adhered to is worn into fine powder and is fallen off from copper rice surface, using selection by winnowing, by lightweight
Paint powder separated with copper rice.
(3) compression moulding: the clean copper rice that step (1), (2) are obtained weighs 30 kilograms, is packed into punching block, is placed in 3500
Copper rice is equably pressed into 940 millimeters long, 100 millimeters wide, thick 40 millimeters of copper to copper rice surface pressure in mould in t hydraulic press
Plate, copper sheet density 8.0g/cm3.
(4) copper anode plate assembly and electrolysis: by the copper sheet of 7 pieces of compression moulding, it is respectively clamped into copper anode hanger, is combined into one
Block copper anode plate, then cloth bag and stainless steel isolation frame are put on, slot can be descended to carry out cupric electrolysis.
Wherein the effect of cloth bag is to collect the copper rice that is scattered, the effect that frame is isolated be prevent cloth bag float in the electrolytic solution with
Cathode contacts adhesion.
Preferably, the punching block inner cavity is high by 300 having a size of long 940mm, wide 100mm.
Beneficial effects of the present invention: the non-melting electrolysis process process of the copper scap compression moulding reduces copper scap and recycles
Traditional smelting technology, thus reduce the energy consumption of fusion process, noxious fume processing, effectively shorten recycling production
Period reduces labor cost, improves metal recovery utilization rate；And have technique is simplified, equipment is simple, less energy consumption,
The advantages that at low cost, pollution is lacked.
