[0029] See also Figure 1 and Figure 2 The embodiment of the utility model discloses an electrolysis device, which is mainly used for electrolyzing and separating alloy materials. An electrolysis device of one embodiment includes an electrolysis box 100, a cylinder 200, a cathode plate 300, a drive assembly and a filter (not shown in the figure). The electrolysis box 100 is filled with an electrolyte 10, and the cylinder 200 is rotatably arranged in the electrolysis box 100. The inner cavity of the cylinder 200 is used to place materials. The cylinder wall of the cylinder 200 is provided with a through hole 210, so as to facilitate the electrolyte 10 to enter the cylinder 200 and contact with the material for electrolysis reaction. The cylinder 200 is a cylindrical structure made of conductive material, the cylinder 200 is an anode, and the cathode plate 300 extends into the electrolyte 10 of the electrolysis box 100. The drive assembly is connected to the cylinder 200 for driving and rotating, so as to peel off the electrolysis products on the surface of the material into the electrolyte 10. The filter is connected to the electrolysis box 100, and is used to filter the electrolysis products in the electrolyte 10 to form a filter.

[0030] It can be understood that the cylinder 200 is a cylindrical structure made of conductive material, the cylinder 200 is the anode, and the cathode plate 300 extends into the electrolyte 10 of the electrolytic box 100. The electrolyte 10 can contact the material through the through hole 210, thereby realizing the electrolysis of the material. At the same time, the driving component drives the cylinder 200 to rotate to peel off the electrolysis products on the surface of the material into the electrolyte 10, so that the electrolysis products can be peeled off from the surface of the material in time to ensure the electrolysis efficiency of the material in the electrolyte 10. After the electrolysis products reach a preset concentration in the electrolyte 10, the filter filters the electrolysis products in the electrolyte 10 to form a filtrate, thereby quickly realizing the separation process of the alloy material, with high separation efficiency and saving labor costs.

[0031] By using the electrolysis device of this embodiment, the alloy material can not only be electrolytically separated in the electrolysis device, but also the electrolysis product can be ball-milled and peeled off, integrating electrolysis and ball milling. Compared with the solid-state electrolysis of existing alloy materials, the electrolysis device of this application can realize dynamic electrolysis of alloy materials, which is more labor-saving and efficient.

[0032] In one embodiment, see Figure 1 and Figure 2 The cylinder 200 is a cylindrical structure made of acid-resistant, high-hardness conductive metal material. The cylinder 200 serves as an anode and has a wide contact area with the alloy material, which can ensure the electrolysis efficiency of each contact surface of the alloy material and improve the reaction speed of the entire electrolysis.

[0033] Furthermore, the electrolysis device further comprises a terminal 900, and the terminal 900 is electrically connected to the cylinder 200 via a wire. Specifically, the cathode plate 300 is disposed close to the cylinder 200 and is gap-matched with the cylinder 200.

[0034] In one embodiment, see Figure 1 and Figure 2 The electrolysis device further includes a first pipeline 610 and a fluid pump 700. One end of the first pipeline 610 is connected to the bottom of the electrolysis box 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 product in the electrolyte 10 is filtered through the filter to form a filter, and the alloy material is quickly separated. Specifically, the filter is a filter press.

[0035] In one embodiment, see Figure 1 and Figure 2 The bottom wall of the electrolytic box 100 is formed with a collecting groove, the groove wall diameter of the collecting groove gradually decreases from top to bottom, and the first pipeline 610 is connected to the lower part of the collecting groove. Through such an arrangement, the electrolysis product will settle in the lower part of the collecting groove under the action of gravity, thereby improving the filtering efficiency of the filter.

[0036] Furthermore, in this embodiment, the electrolysis device also includes 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 box 100, and the other end is connected to the pipeline between the fluid pump 700 and the first valve 810. The second valve 820 is arranged on the second pipeline 620, and is used to open or block the second pipeline 620.

[0037] 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 connected to the second pipeline 620, the electrolyte 10 leaves the electrolytic box 100 from the lower part of the collecting tank, passes through part of the first pipeline 610 and the second pipeline 620, and is transported back to the electrolytic box 100. The circulation of the electrolyte 10 is driven by the fluid pump 700, which can increase the electrolysis reaction speed.

[0038] When the first valve 810 is controlled to conduct the pipeline between the fluid pump 700 and the filter, and the second valve 820 blocks the second pipeline 620, the electrolyte 10 is transported to the filter through the first pipeline 610, and the filter filters the electrolysis products in the electrolyte 10 to form a filtrate, thereby quickly separating the alloy materials. After the electrolysis products in the electrolyte 10 reach a certain concentration, the electrolyte 10 is passed into the filter, and the filter intercepts and filters the electrolysis products in the electrolyte 10 to form a filtrate, and finally the filtrate is discharged to the receiving tray to transfer to the next process.

[0039] By such arrangement, after the alloy material in the cylinder 200 is electrolyzed, it is only necessary to regularly replenish new alloy material to realize the continuous electrolysis reaction, thus eliminating the work of discharging the alloy material and transferring the alloy material, thereby improving production efficiency.

[0040] Specifically, the electrolysis device further includes a third valve 830, which is disposed at the inlet end of the fluid pump 700. When the fluid pump 700 stops working, the third valve 830 can be controlled to close to stop the delivery of the electrolyte 10. Of course, in other embodiments, the first pipeline 610 can also be connected to other parts in the electrolysis box 100.

[0041] In one embodiment, see Figure 1 and Figure 2 The drive assembly includes a drive motor 410, a first gear 420, a second gear 430 and a transmission belt 440. The output shaft of the drive motor 410 is provided with the first gear 420, the cylinder 200 is provided with the second gear 430, and the transmission belt 440 is wound between the first gear 420 and the second gear 430, so as to realize the rotational drive of the cylinder 200. Further, the number of teeth of the first gear 420 is less than the number of teeth of the second gear 430, so that the rate of the rotational motion output by the drive motor 410 can be reduced. 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.

[0042] The cylinder 200 is driven to rotate by the driving assembly arranged in this way. The rapid rotation of the cylinder 200 can have a ball milling effect. The contact and collision between the alloy material and the inner wall of the cylinder 200 can peel off the electrolysis products on the surface of the alloy material and let them fall into the electrolyte 10. In this way, the dense material in the inner layer of the alloy material can be exposed, thereby accelerating the dissolution and separation reaction between the outer layer of the alloy material and the electrolyte 10.

[0043] Of course, in other embodiments, the driving assembly includes a driving motor 410 and a gear box, and the driving motor 410 is drivingly connected to the cylinder 200 via the gear box.

[0044] In one embodiment, see Figure 1 and Figure 2The outer wall of the cylinder 200 is provided with a material opening 220, so that the material is placed in the inner cavity of the cylinder 200 through the material opening 220. Further, the electrolysis device also includes a material door, which is covered and fixed to the material opening 220, so as to confine the material in the cylinder 200.

[0045] In a more specific embodiment, the first group: see Figure 1 and Figure 2 , take 100kg of alloy material and load it into the cylinder 200 of the electrolysis device of this embodiment, inject electrolyte 10 into the electrolysis box 100, the electrolyte 10 is 3.5mol / L sulfuric acid, and the concentration of ballast acid is not less than 2mol / L, start the driving component to drive the cylinder 200 to rotate, the alloy is constantly turned over in the cylinder 200, and at the same time, start the bottom fluid pump 700 to allow the electrolyte 10 to circulate continuously, and fix cathode plates 300 on both sides of the cylinder 200, which are as close to the cylinder 200 as possible, but ensure that the free rotation of the cylinder 200 is not affected. The cylinder 200 is an anode, and direct current is passed for electrolysis:

[0046] The electrolysis lasted for a total of 6 days. The weight of the alloy material in the cylinder 200 was weighed 48.5kg, 34.8kg, 18.3kg, 7.2kg and 0kg after 48h, 72h, 96h, 120h and 144h respectively. 86.4kg of insoluble powder was collected by the bottom fluid pump 700 (this batch of alloy materials was detected by a spectral scanner before the test, and the proportion of soluble matter was about 13.3%), and the material electrolysis completion rate was 100%.

[0047] The second group: 100 kg of alloy material was placed in a static electrolysis basket in the prior art, and the whole was placed in an electrolytic cell. An electrolyte 10 was added. The electrolyte 10 was 3.5 mol / L sulfuric acid, and the concentration of ballast acid was not less than 2 mol / L. Cathode plates 300 were fixed on both sides of the electrolysis basket, and direct current was passed for electrolysis:

[0048] The electrolysis lasted for 6 days in total. After 144 hours (6 days), the alloy material was taken out from the electrolysis basket and put into a ball mill for ball milling. The detachable materials on the surface were separated and weighed and recorded. The recorded data were: 55.9 kg of alloy block remained and 35.7 kg of powder.

[0049] It can be seen that after 144 hours of dynamic electrolysis using the electrolysis device of this embodiment, the weight of the alloy block changes from 100kg to 0kg; after 144 hours of static electrolysis using the electrolysis scheme of the prior art, the weight of the alloy block changes from 100kg to 55.9kg; the electrolysis efficiency increases by 126.7% year-on-year, while reducing material turnover, greatly improving production efficiency and reducing production costs.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
