Embodiment 1

[0127] Embodiment 1, an integrated equipment of a copper melting auxiliary device and a foil production machine, which includes: an anode tank 1, a cathode roller 2, a copper melting rod 3, a liquid feeding pipe 4, and a liquid suction pipe 5;

[0128] The foil machine adopts the upper liquid feeding mode;

[0129] The anode tank 1 is a non-immersed anode tank, and the anode tank 1 is a hollow airtight structure;

[0130] Sulfuric acid is stored in the anode tank 1, and a liquid inlet and an air inlet are arranged on one side of the anode tank 1;

[0131] A liquid-feeding pipe 4 is arranged above the anode tank 1, and the liquid-feeding pipe 4 is connected with the copper melting tank;

[0132] A pumping pipe 5 is also arranged above the anode tank 1;

[0133] The suction pipe 5 is connected with the bottom of the liquid feeding pipe 4;

[0134] The working mode of embodiment 1 is: the anode tank 1 is equipped with high-concentration copper sulfate, and the pumping pipe 5 is ...

Embodiment 2

[0141] The disadvantage of embodiment 2 and embodiment 1 is that the speed of dissolving copper is relatively slow, so it cannot meet the requirement of quickly supplementing copper ions.

[0142] Anode tank 1 is designed as follows:

[0143] Including: first plate 1-1, anion exchange membrane 1-2, second plate 1-3;

[0144] The first plate 1-1 is a titanium plate, which is the first plate and is connected to the positive pole of the power supply;

[0145] The second plate 1-3 adopts a titanium plate, which is a cathode plate, connected to the negative pole of the power supply;

[0146] A sulfuric acid solution is arranged between the first plate and the second plate;

[0147] An anion exchange membrane 1-2 is arranged between the first plate and the second plate, and the anode tank 1 is divided into an anode chamber and a cathode chamber;

[0148] Place the molten copper rod ( figure 2 not shown).

[0149] An oxygen inlet is provided on the side wall of the anode chambe...

Embodiment 3

[0152] Embodiment 3: Embodiment 1 has made it clear that the function of dissolving copper is set in the anode tank, and its purpose is to increase the copper ions between the anode tank and the cathode roller; and between the cathode roller and the first plate, mainly near the cathode roller (That is, the lack of copper ions in the ion-poor area) will affect the production effect of copper foil.

[0153] Here, the design of the applicant's previous application "A Method for Producing Electrolytic Copper Foil with Anode Tank, Foil Raising Machine, and Electrolyte Flow" directly flows the solution of the anode tank into the "copper-poor" area.

[0154] A through hole is provided on the first plate, and a flange extends outside the through hole, and a thread is provided outside the flange; a liquid extractor is arranged in the anode chamber of the anode tank, and the liquid extractor is connected to the liquid outlet pipe, The outlet pipe connects through holes;

[0155] Also i...
