Technical field
The utility model relates to the reclaiming metals system of a kind of electrolyzing and recycling system, particularly a kind of electroplating reverse-flow rinsing process.
Background technology
At electroplating industry, after being electroplated, workpiece carries out the most general cleaning that countercurrent rinsing remains current ability use, conventionally after workpiece is electroplated out groove in bath trough in electroplating reverse-flow rinsing process, from elementary rinse tank to final rinse groove, carry out successively rinsing, tap water enters from final rinse groove after ion exchange treatment, then successively to upper level rinse tank stage by stage step by step guide groove fill into, the rinse water that overflow from elementary rinse tank enter hold tank again and reclaim storage, discharge.Its advantage is can streamline operration, and production efficiency is high, but also can cause plated metal and water resource waste, is difficult to meet the requirement of cleaner production and recycling economy.Chinese patent CN200710113271.8 discloses a kind of electroplating reverse-flow rinsing process, this technique has strengthened the wash effect of electroplating parts by spray equipment is set, by the rinse water by next stage rinse bath, regularly quantitatively to upper level rinse bath, carry out supply simultaneously, greatly saved water resources, but this invention only has a large reverse-flow rinsing process in whole cleaning process, wash effect is not ideal enough, and the recovery method of metal ion is not mentioned in this invention.
Summary of the invention
For addressing the above problem, the utility model provides a kind of reclaiming metals system of electroplating reverse-flow rinsing process, by electrolyzer is set in system, the metal ion in rinsing liquid is reclaimed, the closed circulating that forms a rinsing, electrolysis is processed, and can effectively overcome the problems such as in prior art, the metal ion rate of recovery is low, wash effect is not good.
The technical solution of the utility model is: a kind of reclaiming metals system of electroplating reverse-flow rinsing process, comprise plating tank and rinse tank that order is communicated with, piping system and rinse tank fill cycle pipeline, the rinse tank rising pipe, the recycle pump that are communicated with rinse tank, it is characterized in that being also provided with electrolyzer, electrolyzer respectively with rinse tank and after filtration device be communicated with rinse tank, formation a closed loop the rinsing liquid recycle system, electrolyzer is also connected with apparatus for recovering metal.
The reclaiming metals system of described electroplating reverse-flow rinsing process, is characterized in that rinse tank fill cycle pipeline is provided with reversing valve, and reversing valve two ends are connected with rinse tank rising pipe with recycle pump respectively, forms the self-circulation of rinsing liquid in rinse tank.
Described rinse tank quantity is 3-6.
The beneficial effects of the utility model are: the organic efficiency that effectively raises metal ion in rinse cycle by electrolyzer is set, by the closed circulating of electrolyzer and rinse tank, greatly reduced the water consumption of rinsing process, in rinse tanks at different levels, the self-circulation of rinsing liquid has greatly improved wash effect simultaneously.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the utility model liquid level is controlled and circulation schematic diagram;
Fig. 3 is that schematic diagram is controlled in liquid level commutation of the present utility model.
Embodiment
below in conjunction with accompanying drawing, to originally practical, be newly described in further detail:
As shown in Figure 1, Figure 2, Figure 3 shows, the reclaiming metals system of electroplating reverse-flow rinsing process comprises plating tank 1, elementary rinse tank 2, secondary rinse tank 4, three grades of rinse tanks 5, final rinse groove 6, plating tank and rinse tank at different levels are linked in sequence, rinse tank quantity is generally chosen 3-6, and the present embodiment is chosen 4.Rinse tanks at different levels are connected with respectively rinse tank rising pipe 7 and recycle pump 9, piping system 10 and rinse tank fill cycle pipeline 11, in rinse tanks at different levels, be provided with liquid level switch 3, be used for controlling water level in rinse tank, elementary rinse tank is connected with electrolyzer 12 by electrolyzer water inlet pipe 13, electrolyzer one side is connected with apparatus for recovering metal 15, opposite side is connected with filtration unit 14, filtration unit is connected with final rinse groove by rising pipe 16, at elementary rinse tank, electrolyzer, between filtration unit and rinse tank at different levels, form the rinsing liquid recycle system of a closed loop, realize rinsing and completed again electrolysis.Its specific works process is: electroplating parts enters elementary rinse tank by plating tank, and carries out successively rinsing from elementary rinse tank to final rinse groove.Increase along with electroplating parts quantity, in rinse tanks at different levels, concentration of metal ions improves constantly, now, rinsing liquid in elementary rinse tank is imported to electrolyzer through electrolyzer water inlet pipe, in electrolyzer, rinsing liquid is carried out to ionic absorption and form coated metal, coated metal is imported to apparatus for recovering metal and reclaim.Along with the carrying out of electrolytic process, in electrolyzer, rinsing liquid concentration of metal ions further reduces, and the rinsing liquid after electrolysis enters from final rinse groove after installing after filtration processing, continues to use as electroplating parts rinse water.Rinse water enter three grades, secondary and elementary rinse tank fill cycle pipeline successively by final rinse groove rising pipe, piping system, recycle pump, and supply rinse water are step by step realized the countercurrent rinsing of electroplating parts.
Between recycle pump and rinse tank rising pipe, be provided with reversing valve 8, reversing valve can be realized the self-circulation of rinsing liquid in rinse tanks at different levels.Detailed process is: open reversing valve, make rinsing liquid by recycle pump, enter rinse tank fill cycle pipeline at the corresponding levels by rinse tank rising pipe and piping system, can form the self-circulation whipping process of rinsing liquid in rinse tanks at different levels, greatly improved wash effect.When concentration of metal ions is higher in rinse tanks at different levels, close reversing valve, rinsing liquid enters upper level rinse tank fill cycle pipeline by next stage rinse tank rising pipe successively through recycle pump, realizes the systemic circulation of whole rinsing device.
Native system is simple in structure, system long-time running is reliable and stable, the wash effect of electroplating parts is even more ideal, rinsing workpiece water consumption can be reduced to the 1/20-1/15 of conventional counter-current rinsing process water consumption, can realize simultaneously rinse water closed cycle, realize the zero release of waste water, the water utilization rate of rinsing process process can reach 100%, and the plated metal ion rate of recovery such as copper, silver, gold, palladium, platinum can reach more than 98%.
