[0014] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0015] As shown in FIGS. Figure 1 and Figure 2 A permanent aluminum cathode plate for electro-nickel and electro-cobalt production includes a conductive cross beam 1, a cathode plate 2 and an insulating edge pressing strip 3. The conductive cross beam 1 is made of aluminum alloy material. The conductive cross beam 1 and the cathode plate 2 are fixed by welding. A copper-aluminum composite conductive block 4 is arranged at the end of the conductive cross beam 1. The copper-aluminum composite conductive block 4 includes a composite aluminum block 41 and a composite copper block 42. The composite aluminum block 41 is fixedly connected with the conductive cross beam 1, and the composite copper block 42 is exposed on the surface. The cathode plate 2 is provided with a mirror surface. The insulating edge pressing strip 3 is arranged on the side edge and the bottom edge of the cathode plate 2.

[0016] When the permanent aluminum cathode plate for electro-nickel and electro-cobalt production is manufactured, firstly, the welding surface of the body of the conductive cross beam 1 and the copper-aluminum composite conductive block 4 is polished to remove the oxidation layer, so as to prevent the aluminum material oxidation layer from affecting the conductive property after welding. Then, the welding is rapidly performed. After the welding of the conductive cross beam 1 is completed, the cathode plate 2 and the conductive cross beam 1 are welded. The welding surface also needs to be polished to remove the oxidation layer before welding.

[0017] The conductive cross section of the conductive beam 1 is controlled at 1200-1500mm 2 , to ensure the power flux.

[0018] The thickness of the cathode plate in the above embodiment is different according to the production product, and is adjusted in the range of 3-8mm, the electro-nickel is generally controlled at 3-5mm, and the electro-cobalt is controlled at 5-8mm.

[0019] The copper-aluminum composite conductive block 4 is arranged at one end of the conductive beam 1 in the application, which is based on the following consideration: the conductive beam made of aluminum or aluminum alloy is easily oxidized in the air, and a dense oxide layer is formed on the outer surface of the conductive beam, and when the cathode plate is operated, the conductive beam is conducted by being clamped on the bus. If the conductive beam is made of pure aluminum or aluminum alloy, the conductive efficiency will be affected during operation. Compared with aluminum, copper has better conductive performance than aluminum under the premise of oxidation. Therefore, by welding a copper-aluminum composite conductive block at the current introduction end of the conductive beam, the poor conductivity of the aluminum conductive beam can be solved.

[0020] During the production of the permanent aluminum cathode plate, the cathode plate conductive beam is positioned by the clamping groove arranged on the liquid receiving box on the surface of the electrodeposition tank, and is clamped on the bus on the surface of the electrodeposition tank. The cathode plate and the anode plate are placed at intervals, the current enters from one end of the anode conductive beam through the bus, and the current forms a series loop in sequence from the anode-cathode for electrodeposition operation.

[0021] The permanent aluminum cathode plate for electro-nickel and electro-cobalt provided by the application can solve the problems in the current electro-nickel and electro-cobalt production process, and directly produces electro-nickel and electro-cobalt by this method, which can optimize the electro-nickel and electro-cobalt production process, reduce the labor intensity, and improve the production efficiency and product quality.

[0022] The above is only a specific implementation manner of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
