Description

TECHNICAL FIELD

[0001] The utility model relates to electrolytic copper anode plate processing technical field especially is a kind of anode mud cleaning device and equipment for electrolytic copper foil anode plate. BACKGROUND

[0002] The method of electrolytic copper foil production is mostly adopted by roll cathode, insoluble anode to produce electrolytic copper foil by continuous method. Among them, the roll cathode method is a more common way. In the process of electrolytic copper foil production, in addition to the consumption of raw materials copper and additives, the biggest investment is anode plate. The average service life of anode plate for current standard foil production is 8-12 months, and the service life of battery foil anode plate is only 3-6 months. The consumption of anode plate is an important part of copper foil production cost, so improving its service life is valued by manufacturers. The current electrolytic copper foil uses titanium coating IrO2 anode (titanium matrix + IrO2 coating). Because the oxygen precipitation potential on IrO2 anode is low, the electrolysis voltage is reduced, and a large amount of electric energy can be saved. However, the titanium anode will be covered with a layer of fouling (commonly known as anode mud), causing uneven thickness, oxidation and other defects in copper foil products, and even vertical ribs, which seriously affect its quality. The existing research finds that anode fouling is mainly PbSO4, because there is a certain amount of lead (generally process control ≤20mg / L) in raw materials. During the copper dissolving stage, lead will also dissolve and enter the solution to form a copper dissolving tank with high temperature (about 90℃) and low acid content, so the solubility of lead sulfate is large. PbSO4 enters the foil system machine through the pipeline, and the temperature of the solution decreases (40℃-60℃), PbSO4 is precipitated and deposited on the anode plate to form anode mud.

[0003] At present, the methods for cleaning anode plate mainly include manual high-pressure water gun washing and mechanical brushing: manual high-pressure water gun washing on both sides of anode plate has the disadvantages of low efficiency, large water consumption, incomplete cleaning, etc. Mechanical brushing is to fix brushes on both sides of the anode plate to be washed, and supply washing liquid from a washing liquid tank for mechanical brushing, which has the disadvantages of long cleaning time, low efficiency, easy damage of mechanical brushes, difficult repair and high cost, etc. And the existing cleaning agent is found to cause certain damage to electrolytic copper foil anode plate after several attempts.

DETAILED DESCRIPTION

[0023] The utility model is further explained in combination with the attached drawing and specific embodiment, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0024] Example one

[0025] Referring to Figures 1-2 The utility model discloses an anode plate anode mud cleaning device for electrolytic copper foil, including:

[0026] Cleaning part 1, the cleaning part 1 includes water storage tank 12, liquid medicine tank 11 and cleaning tank 13, the water storage tank 12 is used to store pure water in, the liquid medicine tank 11 is used to store reaction liquid medicine in, the top of cleaning tank 13 is provided with first sprinkling pipe 14 and second sprinkling pipe 15, first sprinkling pipe 14 with liquid medicine tank 11 intercommunication, first sprinkling pipe 14 with liquid medicine tank 11 between setting has first water pump 16, second sprinkling pipe 15 with water storage tank 12 between setting has second water pump 17, second sprinkling pipe 15 with water storage tank 12 intercommunication, the outside of cleaning tank 13 is provided with ultrasonic generator 131 circumferentially;
