Abstract
The invention provides a permanent negative plate for production of a nickel button. The permanent negative plate comprises a conducting bar and a conductive substrate. The conducting bar is connected with the conductive substrate through a conductive rib plate. The conductive substrate comprises a first conductive substrate and a second conductive substrate which are arranged directly facing each other. Outsides of the first and second conductive substrates are respectively provided with an insulating panel. The insulating panels are respectively secured to the first conductive substrate and the second conductive substrate through conductive bolts and locknuts. Each conductive bolt has an umbrella-shaped nail head which is tightly pressed on the outer surface of the insulating panel, and the top surface of the umbrella-shaped nail head is a smooth surface. Gaps between four side edges of the first conductive substrate and four side edges of the second conductive substrate are sealed with an insulating material. According to the negative plate, crack growth of a nickel button can be avoided. After the production, the nickel button is convenient to peel, and it is not easy to damage the insulating panels when the nickel button is peeled. In addition, the negative plate has advantages of long service life, short repair cycle and simple operation.
Description
Technical field
The invention belongs to non-ferrous metal hydrometallurgy field, relate to a kind of permanent cathode plate for the production of nickel button.
Background technology
In electronickelling technique, nickel button (comprising Active Nickel Containing Sulphur button) is application more another kind of nickel anode material except electrolytic nickel.At present, the enterprise that produces nickel button is less, is mainly abroad International Nickel company of Canada Ltd. (INCO), Ying Qiao refinery of Norway, the domestic Chengdu electrometallurgy factory that mainly contains.Nickel button growth substrate---" nickel button negative plate " is that nickel is buckled the key equipment in production process.Nickel button negative plate mainly contains two kinds of forms: pad pasting negative plate and permanent cathode plate.
Pad pasting negative plate is in metal base, to paste a kind of insulation film, is reserved with circular hole on insulation film, and circular hole position exposes metal base, and nickel button is mainly grown in exposed metal base.Pad pasting negative plate due to insulation film must be smooth, bonding force is strong, nickel button will be after loaded down with trivial details treatment process after peeling off pad pasting again, limited its applying in large-scale commercial production.
Permanent cathode plate is long a kind of form of presentation of anticathode plate life cycle or life-span, and abroad, it is take titanium plate as substrate that Ying Qiao refinery produces the negative plate that electrolytic nickle adopts, inlay titanium right cylinder, surface is injection molded through epoxy resin.Domestic permanent cathode plate is invented first and seen Granted publication number is the utility model patent that CN200964444Y, denomination of invention are " negative plate of permanent nickel fastener ".
The structure of analyzing existing permanent cathode plate is known, and the primary structure of existing permanent cathode plate is all damascene conductive cylinder in metal base, and conducting circular cylinder is parcel, fill insulant around.This kind of permanent cathode plate has two large weak points in nickel button production process: (1) is in nickel electrowinning technique, permanent cathode plate is under electrolysis temperature (60 ℃ of >) effect, between insulating material and conducting circular cylinder, easily there is gap, cause nickel button to produce " crack growth ", cause difficulty to peeling off of nickel button, and easily damage the insulating material of permanent cathode plate; (2) permanent cathode plate will face maintenance after the use sufficiently long time, and its maintenance process relates to the removal of insulating material and refills, and this process is very complicated, has increased manufacture and the rehabilitation cost of permanent cathode plate.
Summary of the invention
The object of the invention is to the problem existing for prior art, provide a kind of and avoid the growth of nickel clip seam and overhaul the permanent cathode plate for the production of nickel button easily.
For this reason, the present invention adopts following technical scheme:
A kind of permanent cathode plate for the production of nickel button, comprise busbar and electrically-conductive backing plate, described busbar is connected with electrically-conductive backing plate by conduction gusset, described electrically-conductive backing plate comprises just to the first electrically-conductive backing plate and the second electrically-conductive backing plate that arrange, described the first electrically-conductive backing plate and the second electrically-conductive backing plate fix with conduction gusset respectively, the outside of the first electrically-conductive backing plate and the second electrically-conductive backing plate is respectively equipped with insulcrete, and described insulcrete fixes by contact screw and set nut and the first electrically-conductive backing plate and the second electrically-conductive backing plate; Described contact screw is evenly laid on the first electrically-conductive backing plate and the second electrically-conductive backing plate, and described set nut is positioned at the inner side of the first electrically-conductive backing plate and the second electrically-conductive backing plate; Described contact screw has a umbrella head of a nail, and the described umbrella head of a nail is pressed on insulcrete outside surface, and the end face of the umbrella head of a nail is shiny surface; Gap between the first electrically-conductive backing plate and four sides of the second electrically-conductive backing plate seals by insulating material.
Further, the end face of the described umbrella head of a nail is dome or flat-top.
Further, the bottom surface of the described umbrella head of a nail is inwardly recessed, and the outward flange of the described umbrella head of a nail is embedded in insulcrete.
Further, the set nut on described the first electrically-conductive backing plate and the interlaced setting of set nut on the second electrically-conductive backing plate.Both sides set nut is crisscross arranged and can reduces the thickness of permanent cathode plate, make gap between the electrically-conductive backing plate of both sides less, be easy to sealing, strengthened the intensity of permanent cathode plate simultaneously.
Further, between described the first electrically-conductive backing plate and the second electrically-conductive backing plate, fix by standing bolt, described standing bolt runs through insulcrete and its two ends are coated with insulating material, to prevent that nickel button from growing in the both ends of the surface of standing bolt.
Further, the outer side of described the first electrically-conductive backing plate and the second electrically-conductive backing plate is coated with and is brushed with insulation paste.So can increase the stable connection of insulcrete and the first electrically-conductive backing plate and the second electrically-conductive backing plate, and can increase the planarization of insulcrete.
In the present invention, conduction gusset, electrically-conductive backing plate, contact screw can be stainless steels, can be also titanium materials; The nail pole length of the thickness of set nut and contact screw mates mutually with the thickness of electrically-conductive backing plate and the thickness of insulcrete.Insulcrete adopts thermoplastic engineering plastic, can be polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP), polystyrene (PS) or acrylonitrile-butadiene-phenylethylene co-polymer (ABS).Insulation paste can be thermoplastic cement, can be also any in thermosetting cement.
Beneficial effect of the present invention is: utilize permanent cathode plate of the present invention, nickel button is grown in the outside surface of the contact screw umbrella head of a nail, because the umbrella head of a nail is pressed on insulcrete, avoid nickel to deduct existing " crack growth " phenomenon, production finishes rear nickel button to be convenient to peel off, not fragile insulcrete while peeling off nickel button; In addition, permanent cathode plate long service life of the present invention, the turnaround is short, simple to operate, has reduced nickel button production cost, is suitable for large industrialized and produces.
