Description

Technical Field

[0001] The utility model relates to the technical field of copper foil anti-oxidation, in particular to a filtering device for electrolytic copper foil anti-oxidation equipment. Background Art

[0002] As lithium battery copper foil customers demand higher quality for high-end battery products, the requirements for electrolytic copper foil for lithium batteries are also increasing, such as high tensile strength, high elongation, pinhole resistance, high-temperature oxidation resistance, and good wettability. The manufacturing and use of lithium batteries involve high temperatures. If the electrolytic copper foil's high-temperature oxidation resistance is insufficient, its performance will be affected, and further the performance of the lithium battery.

[0003] The most common passivation technology currently used involves introducing copper foil into an anti-oxidation plating tank, where an anti-oxidation layer is applied via electroplating or chemical plating. However, due to the tendency for copper foil to tear during production, the foil can be drawn into the tank and break, leaving fragments of varying sizes. These fragments are difficult to clean, and a common method is to flush them away with pure water. However, this creates another problem: the fragments accumulate at the outlet of the anti-oxidation liquid storage tank. As the anti-oxidation liquid supply pump operates, they can enter the pump inlet, blocking the pump inlet and causing the anti-oxidation liquid to stop flowing.

[0004] Therefore, it is necessary to provide a filtering device for electrolytic copper foil anti-oxidation equipment to solve the above technical problems. Utility Model Content

[0008] The Y-shaped filter can be detachably mounted on the drain pipe. A filter screen is provided inside the Y-shaped filter. The outer wall of the Y-shaped filter is in the shape of a transparent tube.

[0009] As a preferred technical solution of the present invention, the filtering accuracy of the inner filter screen of the Y-shaped filter is 1 mm.

[0010] As an optimal technical solution of the present utility model, the liquid inlet assembly includes a liquid inlet main pipe, a four-way pipe, a lower spray pipe, an upper spray pipe and a liquid inlet pipe. The upper end of the liquid inlet main pipe is connected to the four-way pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model forms a circulation through the design of the drain valve, Y-shaped filter and drain valve on the drain pipe in conjunction with the overflow pipe. Through the arrangement of the Y-shaped filter, when the anti-oxidation liquid is discharged, the broken foil in the anti-oxidation liquid can be intercepted in the Y-shaped filter, so as to prevent the broken foil from entering the anti-oxidation liquid storage tank and clogging it, resulting in the interruption of the anti-oxidation liquid.
