Abstract

The utility model provides an electroplating recovery device, which comprises an electroplating tank and a liquid medicine recovery tank connected with the electroplating tank through a first conveying pipeline, an electrolytic cell is arranged inside the liquid medicine recovery tank, and the electrolytic cell is transported through a second The pipeline communicates with the electroplating tank. The electroplating recovery device provided by the utility model can electrolytically recover the liquid medicine in the electroplating tank by setting the liquid medicine recovery tank, so as to avoid the environmental pollution caused by the direct discharge of the liquid medicine containing high-concentration heavy metal ions. At the same time, because the electrolytic treatment reduces the concentration of heavy metal ions, the electroplating solution can be recycled and its use efficiency can be improved, thereby saving costs and reducing the waste of water resources.

Description

Electroplating recovery device

technical field

The utility model relates to the field of electroplating, in particular to an electroplating recovery device.

Background technique

In electroplating, it is known that the polarity of the current supplied to the electroplating load is reversed extremely rapidly. Plating occurs when a positive current is supplied to the plating load; and when a negative current is supplied to the load, the plating is interrupted or part of the metal forming the plating layer is decomposed into an electrolyte, whereby crystals forming the plating layer are produced Finer so that the object can be evenly plated.

The electroplating process mainly depends on immersing the workpiece in the liquid medicine, so that the chemical reaction between the liquid medicine and the workpiece is completed. In this process, because the chemical reaction will continuously produce heavy metal ions, when the heavy metal ions reach a certain concentration, the original potion needs to be drained and replaced with a new potion. The liquid medicine discharged contains a large amount of heavy metal ions, such as copper, nickel, etc., which will undoubtedly pollute the environment. On the other hand, in the electroplating process, the potion needs a certain concentration of heavy metal ions to help the etching process, so the direct discharge of the potion will also cause a waste of metal resources.

Contents of the invention

The purpose of the utility model is to provide an electroplating recovery device for recycling electroplating liquid.

The purpose of this utility model is achieved through the following technical solutions.

An electroplating recovery device, comprising an electroplating tank and a chemical recovery tank communicated with the electroplating tank through a first delivery pipeline, an electrolytic cell is arranged inside the chemical recovery tank, and the electrolytic tank is connected to the electroplating tank through a second delivery pipeline. The slots are connected.

Compared with the prior art, the utility model has the beneficial effects that: the electroplating recovery device provided by the utility model can electrolytically recover the liquid medicine in the electroplating tank by setting the liquid medicine recovery tank, so as to avoid the liquid medicine containing high concentration of heavy metal ions from being directly Environmental pollution caused by emissions. At the same time, because the electrolytic treatment reduces the concentration of heavy metal ions, the electroplating solution can be recycled and its use efficiency can be improved, thereby saving costs and reducing the waste of water resources.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

See also shown in Fig. 1, the utility model electroplating recovery device, comprises electroplating tank and the liquid medicine recovery tank that is communicated with this electroplating tank, is provided with an electrolytic cell inside the liquid medicine recovery tank, and this electrolytic cell communicates with electroplating tank through another conveying pipeline .

The electroplating tank is filled with liquid medicine, and the workpiece is placed in the electroplating tank to chemically react with the liquid medicine to realize the electroplating process.

The liquid medicine recovery tank communicates with the electroplating tank, and is used for receiving the liquid medicine whose concentration of heavy metal discharged from the electroplating tank exceeds a predetermined value. The liquid medicine recovery tank realizes the transportation of the liquid medicine through the delivery pipeline.

The electrolytic cell performs electrolytic treatment on the micro-powder in the potion recovery tank, and separates the heavy metal ions, such as copper ions and nickel ions, to realize the electrolytic recovery of heavy metal ions and reduce the content of heavy metal ions in the potion. The potion treated by the electrolytic cell can be transported into the electroplating tank again through the delivery pipeline for the electroplating reaction because the concentration of heavy metals has been reduced. Realize the recycling of potion, and can recover heavy metal ions at the same time.

The electroplating recovery device provided by the utility model can electrolyze and recover the liquid medicine in the electroplating tank by setting the liquid medicine recovery tank, so as to avoid the environmental pollution caused by the direct discharge of the liquid medicine containing high-concentration heavy metal ions. At the same time, because the electrolytic treatment reduces the concentration of heavy metal ions, the electroplating solution can be recycled and its use efficiency can be improved, thereby saving costs and reducing the waste of water resources.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
