Description
Technical field
The utility model relates to electroplating industry, relates in particular to a kind of positively charged ion generating unit that makes electroplating process not change electroplate liquid.
Background technology
In galvanized actual production process, insoluble anode uses very many, it is also referred to as inert anode system, in this electroplating process, because the plated metal ion in the electroplate liquid can constantly reduce, replenish metal ion so must add the standard metal salts solution for preparing, in the process as nickel plating, just must constantly replenish single nickel salt or other nickel salt etc. plating is proceeded, yet, along with the nickel ion in the single nickel salt that replenishes is consumed, sulfate ion or negatively charged ion are retained, and then the electric charge in the plating bath will be uneven, causes electroplating reaction not proceed, so must regularly electroplate liquid be outwelled, reconfigure new electroplate liquid, not only troublesome poeration waste plating bath, and the electroplate liquid environmental pollution of outwelling is serious.In addition, in electroplating process, along with metallic cation reduces gradually, following reaction: 2H because can take place this moment in the acidifying that can become simultaneously
2O=O
2+ 4H
++ 4e
-Or 4OH
-=O
2+ 2H
2O+4e
-(in the alkali plating solution), these two kinds of reactions can cause that all the pH value of solution descends, so must add the compound of adjusting the solution pH value, so both wasted resource, also increase labor force, be awkward, and after adding the compound of adjusting the plating bath pH value, it is stable to keep the plating bath pH value, has a strong impact on electroplating effect and efficient.This type of problem is that people wish the difficult problem that solves always, will make very big contribution to electroplating industry if can solve.
The utility model content
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of positively charged ion generating unit is provided, this positively charged ion generating unit provides metallic cation can for the plating bath in the electroplanting device continuously, thereby need not regularly replace plating bath, can reach the target of energy-saving and emission-reduction, and can keep bath stability, improve electroplating efficiency and product electroplating quality.
Technical scheme: in order to realize above purpose, a kind of positively charged ion generating unit described in the utility model comprises:
Electrolyzer;
Anode is arranged in the electrolyzer and immerses in the plating bath, directly which is provided with coated metal with coated metal or inert metal and makes anode;
Negative electrode is arranged in the electrolyzer and immerses in the electrolytic solution, makes negative electrode with inert metal;
Electrolysis power, it is used for switching between above-mentioned anode and negative electrode and carries out electrolysis; And
The film that stops ion to pass through, it is located between described the electrolyzer interior anode and negative electrode, and electrolyzer is divided into anolyte compartment and cathode compartment.
For the metallic cation in the plating bath is evenly emitted with plating bath, in described anolyte compartment, be provided with regurgitation stream device (being also referred to as anti-backflow device).
Described regurgitation stream device is that polylith dividing plate intermediate phase is staggered up and down at a certain distance and forms.
In order to get better regurgitation stream effect, be provided with the slit between first dividing plate of described regurgitation stream device and the bottom of electrolytic tank.
For the ion that stops cathode compartment enters the anolyte compartment, in order to avoid pollute the plating bath that configures, stop the ion of anolyte compartment to enter cathode compartment simultaneously, keep original ion stabilized in the plating bath, can not outflow, the film that described prevention ion passes through is the RO reverse osmosis membrane.
Beneficial effect: the positively charged ion generating unit that the utility model provides, because anode is provided with coated metal, after energising, coated metal is by electrolysis, generate plated metal ion,, prepare new electroplate liquid again thereby the electroplate liquid that lacks metallic cation need not be outwelled to replenish the metal ion that is consumed in the plating bath, the plating bath continuity is used, prolong its work-ing life, not only can not waste plating bath, reduce production costs, and minimizing reaches the target of energy-saving and emission-reduction to the pollution of environment; Because plated metal ion can be provided incessantly, metallic cation can not reduce, thereby can keep the plating bath pH value stable to a certain extent, has reduced the compound addition of adjusting pH value, improve the stability of plating bath, also improved the electroplating quality of electroplating efficiency and product simultaneously; Owing in the anolyte compartment, be provided with regurgitation stream device, thereby make and electrolyticly have cationic plating bath because the effect of regurgitation stream device can not return near the anodic coating metal by electrolysis once more, guaranteed that positively charged ion is evenly emitted with plating bath in the plating bath, helping positively charged ion generating unit and electroplanting device can both more effectively work, and guarantees the galvanized quality of product.
