[0002] As one of the important parts of the foil machine, the anode tank is mainly used to contain copper sulfate electrolyte. When producing electrolytic copper foil, the copper sulfate electrolyte is pumped from the bottom of the anode tank to between the anode plate and the cathode roller. The cathode roller rotates slowly in the anode tank, and electrolytic copper foil is formed on the surface of the cathode roller through electrochemical principles. In order to maintain a stable copper ion concentration in the anode tank, the liquid needs to be constantly updated, but this will produce acid gas, which will have a negative impact on the workshop environment and the quality of the foil surface;
[0003] A shielding plate is installed on the top of the existing anode tank, and an interface connected to the exhaust fan is opened on the shielding plate, so as to extract the acid gas floating in the anode tank to prevent the acid gas from floating out and affecting the quality of the copper foil; however, the foil production machine with this shielding plate equipped with an exhaust duct and an exhaust fan is a post-added shielding, and the exhaust device cannot effectively shield the front and rear ends of the anode tank, and the effect of extracting the acid gas is not very ideal.

[0009] Furthermore, a reinforcing plate is fixedly connected to the inner top of the overflow trough body; on the one hand, it can avoid leakage at the top of the overflow trough body, and on the other hand, it can also support the shielding plate.
[0010] Furthermore, the exhaust box assembly includes an exhaust box body made of titanium material, the exhaust box body is in an inverted trapezoidal shape, the opening side of the exhaust box body is fixedly connected to the anode tank, the outer side of one end of the exhaust box body is fixedly connected to a second exhaust pipe, and the bottom end of the exhaust box body is fixedly connected to a second overflow pipe.

[0012] Furthermore, the second exhaust pipe and the first exhaust pipe are located on the same side, which is convenient for connecting with the exhaust fan and reducing the number of branch pipes.

[0024] See also Figure 1-Figure 4 As shown, an electrolytic copper foil anode tank exhaust and overflow device comprises an anode tank 1, an overflow tank assembly 2 is oppositely arranged at the front and rear ends of the anode tank 1, a shielding plate 4 is installed above the overflow tank assembly 2, and two sets of exhaust box assemblies 3 are oppositely arranged on both axial sides of the anode tank 1;
[0025] The overflow tank assembly 2 includes an overflow tank body 201 made of titanium material. The cross section of the overflow tank body 201 is L-shaped. The overflow tank body 201 is fixedly connected to the anode tank 1. The outer side of the overflow tank body 201 is fixedly connected with two first exhaust pipes 202 arranged opposite to each other. The bottom end of the overflow tank body 201 is fixedly connected with two first overflow pipes 203 arranged opposite to each other. The ends of the first exhaust pipe 202 and the first overflow pipe 203 are both provided with flanges. Two liquid baffles 204 are oppositely arranged inside the overflow tank body 201. The two liquid baffles 204 are respectively matched with the pipe openings of the two first exhaust pipes 202 to wrap the pipe openings of the first exhaust pipes 202 inside. A reinforcing plate 205 is fixedly connected to the inner top end of the overflow tank body 201.
[0026] The exhaust box assembly 3 includes an exhaust box body 301 made of titanium material. The exhaust box body 301 is in an inverted trapezoidal shape. The open side of the exhaust box body 301 is fixedly connected to the anode tank 1. A second exhaust pipe 302 is fixedly connected to the outer side of one end of the exhaust box body 301.

Two cleaning ports are oppositely opened at the top of the exhaust box body 301, and a cover plate 304 is sealed and installed on the cleaning port.
[0027] Working principle:
[0028] During production, the shielding plate 4 covers the gap between the cathode roller and the anode tank 1 as much as possible. When the copper sulfate electrolyte overflows into the overflow tank body 201, the overflowed copper sulfate electrolyte can be discharged in time through the first overflow pipe 203. The liquid baffle plate 204 surrounds the pipe opening of the first exhaust pipe 202. When the liquid level of the copper sulfate electrolyte exceeds the pipe opening height of the first exhaust pipe 202, the liquid baffle plate 204 can prevent the copper sulfate electrolyte from entering the first exhaust pipe 202, thereby avoiding the influence on the removal of acid gas.
[0029] When acid gas is generated in the anode tank 1, a small amount of acid gas will also enter the overflow tank body 201. The exhaust fan is started, and the exhaust end of the exhaust fan is connected to the first exhaust pipe 202 and the second exhaust pipe 302 respectively. The first exhaust pipe 202 discharges the acid gas in the overflow tank body 201, and the second exhaust pipe 302 discharges the acid gas in the anode tank 1 through the exhaust box body 301, and discharges it to the outdoors or a designated area through the air duct to improve the workshop environment;
[0030] When dust or impurities exist in the exhaust box body 301 , the cover plate 304 can be opened to clean the inside of the exhaust box body 301 through the cleaning port, and the cleaning liquid is discharged through the second overflow pipe 303 .
