[0032] By using the electrolytic device of the embodiment, the alloy materials can not only be electrolytically separated in the electrolytic device, but also be ball-milled and stripped, so that the electrolysis and the ball milling are integrated. Compared with the solid-state electrolysis of the existing alloy materials, the electrolytic device of the present application can realize dynamic electrolysis of the alloy materials, which is more labor-saving and efficient.

[0033] In an embodiment, referring to FIG. 1 and FIG. 2, the cylinder body 200 is a cylindrical structure made of an acid-resistant and high-hardness conductive metal material, the cylinder body 200 as an anode has a wide contact area with the alloy materials, which can ensure the electrolysis efficiency of each contact surface of the alloy materials and improve the reaction speed of the entire electrolysis.

[0034] Further, the electrolytic device further comprises a terminal post 900, the terminal post 900 is connected between the cylinder body 200 and the electrolyte 10 through a wire. Specifically, the cathode plate 300 is arranged close to the cylinder body 200 and is in gap cooperation with the cylinder body 200.

[0035] In an embodiment, referring to FIG. 1 and FIG. 2, the electrolysis device further comprises a first pipeline 610 and a fluid pump 700, one end of the first pipeline 610 is connected to the bottom of the electrolysis tank 100, and the other end is connected to the inlet of the filter, the fluid pump 700 is arranged in the first pipeline 610 and is used to drive the electrolyte 10 to be transported to the filter, so that the electrolysis products in the electrolyte 10 are filtered by the filter to form filter products, and the separation of the alloy material is quickly realized. Specifically, the filter is a filter press.

[0036] In an embodiment, referring to FIG. 1 and FIG. 2, the bottom wall of the electrolysis tank 100 is formed with a collection groove, the groove wall of the collection groove gradually decreases from top to bottom, and the first pipeline 610 is connected to the lower part of the collection groove. Through such arrangement, the electrolysis products will be precipitated in the lower part of the collection groove under the action of gravity, thereby improving the filtering efficiency of the filter.

[0037] Further, in the embodiment, the electrolysis device further comprises a second pipeline 620, a first valve 810 and a second valve 820, the first valve 810 is arranged on the pipeline between the fluid pump 700 and the filter and is used to open or block the pipeline between the fluid pump 700 and the filter, one end of the second pipeline 620 extends into the electrolysis tank 100, and the other end is connected to the pipeline between the fluid pump 700 and the first valve 810, and the second valve 820 is arranged on the second pipeline 620 and is used to open or block the second pipeline 620.

[0038] When the first valve 810 is controlled to block the pipeline between the fluid pump 700 and the filter, and the second valve 820 is controlled to open the second pipeline 620, the electrolyte 10 leaves the electrolysis tank 100 from the lower part of the collection groove, and is transported back to the electrolysis tank 100 after passing through part of the first pipeline 610 and the second pipeline 620, and the circulation of the electrolyte 10 driven by the fluid pump 700 can improve the electrolysis reaction speed.

After the electrolysis products in the electrolyte 10 reach a certain concentration, the electrolyte 10 is introduced into the filter, the filter intercepts and filters the electrolysis products in the electrolyte 10 to form filter products, and finally the filter products are discharged to the material receiving tray and transferred to the next process.

[0040] Through such arrangement, after the alloy material in the barrel body 200 is electrolyzed, only new alloy material needs to be supplemented periodically to realize the continuous electrolysis reaction, and the work of discharging and material transfer is saved, thereby improving the production efficiency.

[0041] Specifically, the electrolysis device further comprises a third valve 830, which is arranged at the inlet end of the fluid pump 700. When the fluid pump 700 stops working, the third valve 830 can be controlled to be closed to stop the delivery of the electrolyte 10.

Further, the number of teeth of the first gear 420 is less than the number of teeth of the second gear 430, so as to reduce the speed of the rotary motion output by the driving motor 410. Specifically, the transmission belt 440 can be selected as a belt, and the diameter of the first gear 420 is less than the diameter of the second gear 430.

[0043] The driving assembly arranged in this way drives the barrel 200 to rotate. The rapid rotation of the barrel 200 can have a ball milling effect. The contact and collision of the alloy material with the inner wall of the barrel 200 can strip and fall the electrolytic products on the surface layer of the alloy material into the electrolyte 10.

[0047] The total electrolysis time is 6 days. The weights of the alloy material in the cylinder 200 after electrolysis for 48h, 72h, 96h, 120h and 144h are 48.5kg, 34.8kg, 18.3kg, 7.2kg and 0kg respectively. The insoluble powder collected by the bottom fluid pump 700 is 86.4kg (the soluble substance ratio of the alloy material in this batch is about 13.3% detected by a spectrum scanner before the test), and the material electrolysis completion rate is 100%.

[0048] The second group: 100kg of alloy material is placed in the static electrolysis basket in the prior art, and the whole is put into the electrolysis tank.
