Problems solved by technology
This scheme has obviously been greatly improved. However, the scheme does not describe the principle and scheme of the tank turning, that is to say, how to obtain the dynamic balance design scheme between the cleaning tanks is not clear, and it is also because In this way, it is difficult for the equipment to realize automatic operation
In addition, setting up a heating tank to concentrate the transition liquid requires a lot of power consumption
Third, the program still has a certain amount of electroplating wastewater discharged
This method has a similar principle to the countercurrent rinsing process. However, its control conditions are relatively strict, that is, the amount of water sprayed when the micro atomization cleaning meets the cleaning requirements must be consistent with the amount of water brought out of the electroplating tank, in order to achieve real No emission, this process is more difficult to adjust the atomization process for electroplating products with various styles

Embodiment
[0033] In the continuous copper plating production of steel wire, this equipment is used, and three rinsing tanks are set up. The main components of the electroplating solution are: copper sulfate 200 g / L, sulfuric acid 80 g / L, other additives 1 g / L, and the rest is water. The volume of each rinsing tank is 100 cubic centimeters. After one cycle (7 days), all the rinsing liquid in the first tank is pumped to the natural diversion concentration device (after being concentrated to the original concentration of the electroplating solution, it is filtered and pumped back to the electroplating tank), and then Invert the 2nd to 1st tank, the 3rd tank to the 2nd tank, and finally add 100 cubic centimeters of fresh water to the 3rd tank. Such a cycle realizes that only a small amount of fresh water is added, and the rinsing water is not discharged at all. After the production assessment of the bimetallic composite wire with a diameter of 1 mm and a copper plating thickness of 30 microns,...

Abstract
At present, the electroplating production has the defects of large consumption of rinsing water, high cost of waste water treatment and the like. The invention provides a continuous electroplating zero-discharge automatic production device, which comprises an automatic control system, an electroplating system, a rinsing system, a surge chamber system and a concentration system, wherein the electroplating system, the rinsing system, the surge chamber system and the concentration system are connected to the automatic control system through control lines, and each action treatment is also controlled and completed through the automatic control system. The concentration system adopts the unique rectification dispersion design, and can be matched with the concentration change of each rinsing tank, so the goal of zero discharge can be realized. All systems are integrated to become a sealed whole body. The device can realize the clean, tidy and efficient electroplating production.
Description
(1) Technical field [0001] The invention relates to a complete set of continuous production equipment for zero discharge of rinsing water used in the electroplating industry. (2) Background technology [0002] If the rinse water in industrial production, especially in electroplating production, is discharged directly without treatment, it will bring great harm to the natural environment and human life. Therefore, in recent years, people have carried out a lot of research To eliminate or reduce the flow of toxic substances in rinsing water to nature, on the one hand, reduce or completely eliminate the use and production of highly toxic substances by carrying out cyanide-free electroplating, low-chromium or chromium-free passivation, on the other hand, by treating rinsing wastewater For example, ion exchange and other methods are used to reduce the discharge of harmful substances along with the rinsing water, so that the rinsing wastewater can finally meet the national allowab...
