Device for removing impurity zinc and impurity copper in nickel tank liquid

The utility model relates to a device for removing impurity zinc and impurity copper in nickel tank liquid which is mainly used for removing the impurity zinc and impurity copper of the nickel plating liquid. The utility model comprises a machine body, a rectifier and a corrosion-resistant pump, and an electrolytic tank which is provided with an outlet and an inlet. The utility model is characterized in that; groups of cathode and anode are arranged at the inner of the electrolytic tank and are connected with the rectifier, and the inlet of the electrolytic tank is connected with the corrosion-resistant pump. The device for removing impurity zinc and impurity copper in nickel tank liquid has the advantages that the simple and rational structure design is achieved; the electrolytic tank has a big cathode area, so quick electrolytic speed, quick impurity removing and low nickel consume can be realized; the electrolytic tank is used to separate out the impurity zinc and the impurity copper, so the accumulation of the impurity zinc and the impurity copper in the nickel slot can be avoided, and the quality of the plating piece can be assured; the impurity zinc and the impurity copper can be separated out by the electrolytic action, so the PH value can be decreased automatically, the normal electroplating production is not affected, and the impurity removing and the production can be realized at the same time.
