Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production, in particular to a chloride ion adding device. Background Art

[0002] Chloride ion (Cl-) is a -1 valence ion that plays an important role in copper foil production. In the preparation of copper sulfate electrolyte during copper foil production, chloride ion materials need to be added to adjust the properties of copper sulfate electrolyte, which can improve the electrode reaction rate and inhibit the generation of impurities.

[0003] There are two ways to add chloride ions. One is the traditional one-time addition method, which adds the chloride ion material all at once, and the other is to add an appropriate amount continuously. Among them, the one-time addition method has a long stable period search process at the beginning of production, and the addition amount and adsorption amount are not constant, which is difficult to control. The method of continuous addition of an appropriate amount is easy to find the addition amount ratio, which is conducive to finding and maintaining the stable period. The control of the addition amount is the key to affecting production.

[0004] Existing chloride ion continuous addition devices usually use flow valves and other technologies to control the flow of chloride ion solution. The flow valve is usually set in the area of ​​the tank body close to the reserve solution, and the chloride ion solution relies on self-weight overflow to enter the copper sulfate electrolyte tank. However, due to different production line equipment, there is often a certain height difference between the existing chloride ion addition device tank body and the copper sulfate electrolyte tank. The chloride ion solution is affected by gravity in the pipeline. Faced with different height differences in different production lines, the speed at which the chloride ion solution enters the copper sulfate electrolyte tank will be different. The lack of precise control over the addition of chloride ion solution may lead to an unstable reaction, which has a negative impact on the uniformity and continuity of the addition. In addition, the chloride ion addition device has poor adaptability to different production lines. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a chloride ion adding device, aiming to solve the problems of insufficient addition uniformity and poor adaptability to different production lines in the prior art chloride ion adding device.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: by setting the constant pressure gas input pipe, constant pressure gas is input into the tank body, which helps to maintain a constant pressure in the tank body and is beneficial to improving the stability of the chloride ion solution output from the tank body; by setting the first flow control valve and the second flow control valve, and using the DCS module to control the parameters of the two flow control valves, the addition amount and addition speed of the chloride ion solution can be conveniently and accurately controlled.
