Description

Background
Copper foil is an extremely thin material of copper, and copper alloy sheets and strips having a thickness of 100 μm or less are conventionally called copper foil. Electrolytic copper foil is an important material for printed circuit boards, and is mainly used in the fields of electronic computers, industrial control, aerospace and all electric appliances. In recent years, the domestic electronic information industry has rapidly developed, and the copper foil requirements of printed circuit boards and upstream products thereof have increased. In China, copper foil is mostly produced by an electrolytic method, and electrolyte preparation is the first process of electrolytic copper foil production, mainly comprising the steps of dissolving copper materials into sulfuric acid solution, and preparing electrolyte with qualified components and high purity through a series of filtration and purification. The quality of the electrolyte directly influences the quality of the copper foil product, not only the internal quality of the copper foil, but also the appearance quality of the copper foil. Once the components or purity of the electrolyte cannot meet the requirements of electrolytic copper foil manufacture, the quality of copper foil products is caused, and certain economic loss is caused for related enterprises.
The application number is: the patent document of CN202010257661.8 discloses a liquid making device for producing electrolytic copper foil, which comprises a liquid making main box body, wherein a solid inlet and a liquid inlet are formed in the liquid making main box body, and a rotary lifting power device is arranged at the top of the liquid making main box body; a first baffle is arranged at the bottom of the liquid making main box body, and a heat insulation baffle is arranged at the lower part of the first baffle; a heating resistance wire is arranged at a hollow position between the first baffle plate and the heat insulation baffle plate; an active carbon layer is arranged at the lower part of the heat insulation baffle; a mechanical filter is arranged at the bottom of the liquid making main box body; the periphery of the liquid-making main box body is respectively provided with a first air-separating machine and a second air-separating machine. The device can ensure that copper powder and the introduced oxygen fully reflect the generation of copper oxide, and can ensure that the generated copper oxide fully reacts with dilute sulfuric acid, so that the components of the prepared copper sulfate solution are uniform. Meanwhile, the acid mist generated when the concentrated sulfuric acid is dissolved with the pure water can be ensured to be fully dissolved in the solution, and the environment is not polluted.
However, the following disadvantages still exist in the practical application process:
first, the oxidation effect is poor because the copper material is stacked in the main liquid-making tank and oxidized by heating and oxygen-introducing, but this does not oxidize all copper material well, and although the stirring device is provided, the stirring device does not stir copper material sufficiently, that is, some copper material cannot be contacted with oxygen sufficiently.
Second, the safety is poor because the generated acid mist cannot be completely recovered when the copper sulfate solution is produced, because the pressure inside the tank is increased by the heat released when the concentrated sulfuric acid and the pure water are mixed, and if the concentrated sulfuric acid and the pure water are directly circulated, the pressure inside the tank is not changed, and leakage occurs.
