Abstract
The invention is an external nickel sulfate plating solution circulating purifier, comprising pre-reaction region, static flow guide settling region, buffer region, microfilter, etc, able to effectively remove ions of Cu, Fe, Zn, Pb, Cr, and other impurity metallic ions and aged colloids from the plating solution, and simultaneously not losing main nickel sulfate and additive, and after purified, the impurity content is less than 0.01%. And it adopts external circulating purification process, therefore able to implement continuous production and high-quality plating and able to be widely applied to plating solution purification, nickel sulfate production and purification, etc, in plating industry.
Description
Affiliated technical field
The present invention relates to a kind of external nickelous sulfate plating liquid circulating purifying device, it belongs to the chemical industry environmental protection class, specifically is a kind of impurity that can effectively remove in the nickelous sulfate plating liquid, makes the technology of its recycle.
Background technology
Traditional electroplating technology is generally Cu/Ni/Cr, plates layer of copper earlier as bottom before nickel plating, to improve the bonding force of overlay coating and metallic matrix.Plating piece is brought the part copper ion into nickel plating process inevitably, impurity such as the iron that also have in the water simultaneously or additive etc. introduced, zinc, lead, and phenomenons such as pin hole, blackout can appear in coating after running up to a certain degree, have a strong impact on electroplating quality.With the difference of electroplating technology level, the speed of accumulation is difference slightly also, and the particularly manual impurities accumulation speed of electroplating is fast, and phenomenon is obvious.At present treatment process has electrolytic process, activated carbon filter process, have in addition directly scrap.It is that present electroplating industry is used more general a kind of method that electrolytic process is handled, and can effectively reduce the concentration of foreign ions such as copper, lead, zinc, chromium.But it is low to remove efficient, and electrolysing period is long, can not continuous electroplating, and general employing of Electroplate Factory works by day, and night, scrap products still appearred in electrolytic mode often, and plating bath needs big processing once about average half a year; Activated carbon filter process utilizes activated carbon, and it has the good adsorption performance to copper, chromium, lead etc. and relatively poor to the absorption property of nickel, can effectively remove impurity such as copper in the plating bath, chromium, lead, organism.But because gac can adsorb additive (brightening agent, wetting agent etc.) simultaneously, must replenish again after the filtration, otherwise can influence the light of plating piece and increase coating stress etc., and carbon fiber comes off easily, also can produce certain negative impact plating bath.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, the invention provides a kind of external nickelous sulfate plating liquid circulating purifying device.This device can effectively be removed foreign metal ion and aging micelles such as copper in the plating bath, iron, zinc, lead, chromium, do not lose simultaneously main salt single nickel salt and additive, purify rear impurity content less than 0.01%, because this device adopts external placed type circularly purifying technology, therefore can realize continuous production and high-quality plating.
The technical solution adopted for the present invention to solve the technical problems is: the part tank liquor is introduced pre-reaction zone from coating bath, add " strange impurity elimination agent in composite " and use the water pump internal recycle to mix, send into static water conservancy diversion settling region then, under near the condition of static state deposition, most contamination precipitations are removed, (the diameter about 0.3～0.8mm) of aged micelle in impurity that particle is less and the plating bath, behind micro-filtration (filter core precision 0.3 μ m), can remove fully, the filtrate filtered foreign matter content can return coating bath and use less than 0.01%.
The invention has the beneficial effects as follows, can purify tank liquor simultaneously that the foreign matter content after the purification is less than 0.01%, and do not lose effective constituents such as main salt and additive at quantity-produced.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Accompanying drawing is a technological principle synoptic diagram of the present invention
Among the figure 1, water pump 2, composite in strange impurity elimination agent 3, pre-reaction zone 4, static water conservancy diversion settling region 5, buffer zone 6, booster water pump 7, micro-strainer 8, high-order water distributing area
Embodiment
In the accompanying drawings, plating bath to be clean at first enters pre-reaction zone 3, through add composite in after the strange impurity elimination agent 2, mix by water pump 1 internal recycle, medicament is fully contacted with foreign ion in the plating bath and react (medicament not with main reactant salt), mix after water pump 1 is squeezed in the high-order water distributing area 8, gravity flow enters static water conservancy diversion settling region 4, by regulating motorized valve aperture may command flooding velocity.Under near the condition of static state deposition, can effectively precipitate the impurity of removing in the water, sediment further reclaim(ed) sulfuric acid copper after mummification, water outlet enters buffer zone 5, go into micro-strainer 7 through booster water pump 6 superchargings are laggard, can remove aged micelle in above particulate matter of 0.3 μ m and the electroplate liquid, filtrate is returned coating bath and is recycled.
Application example of the present invention is: certain Electroplate Factory, 4 of manual electroplating assembly lines are because the phenomenon that the tank liquor impurities accumulation influences electroplating quality often appears in the restriction of various factorss such as production management level, operator quality, tank liquor is scrapped comparatively fast, and average 2 wheat harvesting periods are scrapped once.Adopt the present invention, to the plating bath purification once the tank liquor quality was more stable in 10～15 days, and plating quality is better, does not occur scrapping plating piece over the past half year.
Claims (3)
1, a kind of external nickelous sulfate plating liquid circulating purifying device, mainly form by pre-reaction zone, high-order water distributing area, static water conservancy diversion settling region, buffer zone, micro-strainer etc., it is characterized in that: tank liquor to be clean enters high-order water distributing area after the strange abundant contact reacts of impurity elimination agent in the pre-reaction zone adding is composite, gravity flow enters static water conservancy diversion settling region then, under near static condition, precipitate, buffer zone is advanced in the water outlet of post precipitation, go into micro-strainer through the pump supercharging is laggard, remove aged micelle in above particulate matter of 0.3 μ m and the electroplate liquid, filtrate is returned coating bath and is recycled.
2, according to the described external nickelous sulfate plating liquid circulating purifying device of claim 1, it is characterized in that: remove earlier the settled impurity particles of the particle overwhelming majority, remove aged micelle in particulate matter more than the 0.3 μ m and the electroplate liquid by micro-strainer again in the settling region.
3, external nickelous sulfate plating liquid circulating purifying device according to claim 1 is characterized in that: adopt the mode of external placed type circularly purifying, can realize continuous electroplating.
