Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of reverse osmosis membrane apparatus in the utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
The utility model discloses a kind of electroplating wastewater recycle device, as Fig. 1, shown in 2, comprise electroplating bath 100, electroplate rinsing groove 200, electroplating wastewater is collected water tank 300, high-pressure pump 400, reverse osmosis membrane apparatus 500, water conductivity checkout gear 550 and pipeline 600, described electroplate rinsing groove 200, electroplating wastewater is collected water tank 300, high-pressure pump 400 and reverse osmosis membrane apparatus 500 connect successively by pipeline 600, the waste water of electroplate rinsing groove 200 flows to reverse osmosis membrane apparatus 500 by pipeline 600 and carries out hydrone permeability and separation, pure water after reverse osmosis membrane apparatus 500 infiltrations flows back to electroplate rinsing groove 200 by pipeline 600, high concentration containing metal concentrate after infiltration flows back to electroplating bath 100 by pipeline 600.
In practical application, in order to facilitate the processing in electroplating wastewater, reverse osmosis membrane apparatus 500 comprises a square casing, and box house is provided with the semi-transparent rete 580 that can only see through hydrone, and casing is separated to form the first cavity 520 and the second cavity 530 by semi-transparent rete 580. The first cavity 520 is provided with water inlet 560, and water inlet 560 connects high-pressure pump 400, the first cavitys 520 by pipeline 600 and is also provided with liquid outlet 570, and liquid outlet 570 connects electroplating bath 100 by pipeline 600; The second cavity 530 is provided with delivery port 540, and delivery port 540 connects electroplate rinsing groove 200 by pipeline 600.
In practical application, in order to reach the object of counter-infiltration, in the first cavity 520, be provided with a propeller 510 for pressurization downwards, to electroplating wastewater pressurization, make the hydrone in electroplating wastewater enter the second cavity 530 through pellicle 580.
In practical application, in order to check purity and the monitoring reverse osmosis unit 500 through the water of pellicle 580, in the second cavity 530, be provided with water conductivity checkout gear 550.
The course of work of the present utility model is as follows: the plating element (not drawing in figure) after electroplating bath 100 has been electroplated, move on in electroplate rinsing groove 200 and carry out rinsing with pure water, the electroplating wastewater that rinsing produces is flowed in electroplating wastewater collection water tank 300 and is collected by pipeline 600. high-pressure pump 400 is worked, by pipeline 600, the electroplating wastewater of collection is pumped to in the first cavity 520 in reverse osmosis membrane apparatus 500, (water inlet 560 of the first cavity is now opened, liquid outlet 570 is closed), in the time that the electroplating wastewater in the first cavity 520 reaches certain amount, close the water inlet 560 of high-pressure pump 400 and the first cavity 520, then reverse osmosis membrane apparatus 500 is started working, propeller 510 in the first cavity 520 is exerted pressure to the electroplating wastewater liquid level in chamber downwards, under the ordering about of pressure, hydrone in electroplating wastewater sees through pellicle 580 and enters the second cavity 530 that pure water is housed, because angle of rake pressure is greater than the osmotic pressure of two empty intracavity liquids, therefore hydrone can not see through pellicle 580 from the second cavity 530 along the direction of osmotic pressure and enter the first cavity 520, having realized effective counter-infiltration is divided into two (being divided into pure water and metallic concentrate) electroplating wastewater, pure water is by the delivery port 540 of the second cavity 530, along with pipeline 600 flows back to electroplate rinsing groove 200, metallic concentrate flows back to electroplating bath 100 by the liquid outlet 570 of the first cavity 520 to be reused, make so whole process not discharge, the concentrated solution of metal and water are all recycled utilization. and be arranged on the water conductivity checkout gear 550 in the second cavity 530, moment is detected pure electrical conductivity of water, rinsing water has quality requirement, the purer electricity of purity of water is led lower, meanwhile, once pure electrical conductivity of water becomes greatly suddenly, this just illustrates that reverse osmosis unit goes wrong, so conductivity detector 550 also plays the effect of monitoring reverse osmosis unit 500 in playing the effect of detection pure water water quality.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
