[0002] Molybdenum-99 (Mo-99) is the most widely used medical radioisotope in clinical practice in my country. In related technologies, when obtaining Mo-99, a uranium dioxide coating can be first deposited on the surface of an alloy tube through electrodeposition technology. The alloy tube covered with a uranium dioxide coating can be used as an irradiated target. Under the action of irradiation, the uranium in the uranium dioxide coating of the target is fissioned to generate Mo-99, and then Mo-99 is finally obtained through procedures such as dissolving the target and chemical separation.

[0003] However, when the uranium dioxide coating is electrodeposited on the surface of the alloy tube, the concentration of the electrodeposition solution may be uneven, resulting in concentration polarization, which affects the efficiency of the electrodeposition. Summary of the invention

[0027] An embodiment of the present invention provides a support device for an electrodeposited electrode. The electrode is tubular, and the support device includes: a plurality of support tubes, the support tubes are elastic, and the support tubes are configured to be able to contract radially inward to extend into the electrode, and support the electrode in the electrode by a radially outward restoring force; a connecting member, the plurality of support tubes are fixedly connected to the connecting member, and the connecting member is used to connect to an external power source to power the electrode; and a rotating assembly is connected to the connecting member, and the rotating assembly is used to drive the connecting member to rotate.

[0028] The supporting device for the electrodeposition electrode provided in the embodiment of the present invention drives the connecting part to rotate through the rotating component, thereby driving the electrode on the connecting part to rotate. When electrodeposition is performed, the cathode is located in the electrodeposition liquid. The rotation of multiple cathodes can stir the electrodeposition liquid, increase the disturbance of the electrodeposition liquid, and make the concentration distribution in the electrodeposition liquid more uniform, thereby preventing the occurrence of concentration polarization.

[0029] The supporting device of the electrodeposition electrode provided in the embodiment of the present invention can be applied to the electrodeposition system. The structure of the supporting device of the electrodeposition electrode provided in the embodiment of the present invention is described below by taking the supporting device of the electrodeposition electrode used to support the cathode of the electrodeposition system, that is, taking the supporting device of the electrodeposition electrode as the cathode supporting device as an example. It can be understood that the supporting device of the electrodeposition electrode can also support the anode of the electrodeposition system, which will not be described in detail below.

[0030] like Figure 1 and Figure 2 As shown, the electrodeposition system may include: an electrodeposition liquid container 100, a heating container 200, an anode support 300, a cathode support device 400 and other structures.

[0031] The electrodeposition liquid container 100 is used to hold the electrodeposition liquid. An opening may be provided at the top of the electrodeposition container, that is, the electrodeposition container is an open container, and the opening may be used for placing and removing the cathode 500 and the anode. In some embodiments, the electrodeposition container may be a pool structure to accommodate the electrodeposition liquid. In some embodiments, the electrodeposition container may be square to maximize the use of space.

[0032] In some embodiments, the electrodeposition system can be used to prepare irradiated targets, that is, the alloy tube is used as a cathode, and uranium dioxide is electrodeposited on the surface of the alloy tube by the electrodeposition system in the embodiment of the present invention, thereby obtaining an irradiated target, which can cause uranium fission to generate molybdenum-99 after irradiation. When the uranium dioxide is electrodeposited, the electrodeposition solution contains nitric acid, and the electrodeposition temperature reaches 90°C. Therefore, the electrodeposition solution container 100 can be made of acid-resistant and high-temperature-resistant materials, such as glass fiber reinforced plastic tank materials, chemical ceramics, chemical enamel, quartz glass and other materials.

[0033] In some embodiments, the electrodeposition liquid container 100 can be made of polytetrafluoroethylene. The materials such as glass fiber reinforced plastic tank, chemical ceramics, chemical enamel, quartz glass, etc. are brittle and not resistant to impact and vibration. In contrast, polytetrafluoroethylene can be acid-resistant and high-temperature-resistant, easy to process, and resistant to impact and vibration. In addition, polytetrafluoroethylene also has good insulation properties, which further improves the safety of the electrodeposition system. In this embodiment, the electrodeposition liquid container is made of polytetrafluoroethylene material, which can meet the requirements of high temperature resistance, acid and alkali resistance, and insulation of the electrodeposition liquid container.

[0034] The heating container 200 is used to heat the electrodeposition liquid in the electrodeposition liquid container 100. The electrodeposition liquid container 100 can be arranged in the heating container 200, and the heating container 200 forms a space for accommodating the electrodeposition liquid container 100. A heating medium is contained in the heating container 200, and the heating container 200 can heat the heating medium, thereby indirectly heating the electrodeposition liquid in the electrodeposition liquid container 100 using the heating medium.

[0035] In this embodiment, the heating container 200 heats the electrodeposition liquid in the electrodeposition liquid container 100 through a heating medium to provide a more uniform heating temperature for different positions of the electrodeposition liquid container 100. The heating medium may be a fluid medium, such as water, oil, etc. In some embodiments, the heating medium may be oil, which has a higher boiling point than water and can provide a higher heating temperature.

[0036] In some embodiments, the heating container 200 needs to provide a heating temperature within a predetermined range. For example, when preparing an irradiated target covered with a uranium dioxide coating, the heating temperature can be around 90°C. Therefore, in some embodiments, the electrodeposition system may include a temperature measuring device and a heating controller. The temperature measuring device is provided on the heating container 200 to measure the temperature of the heating container 200. The heating controller is connected to the heating container 200 and the temperature measuring device to control the heating of the heating container 200 according to the temperature measured by the temperature measuring device. By providing a temperature measuring device and a heating controller, the temperature of the heating container 200 can be controlled within a predetermined range, so as to control the temperature of the electrodeposition liquid to remain within a predetermined range and ensure the normal progress of the electrodeposition.

[0037] The electrodeposition system has an anode and a cathode, and the anode and cathode of the electrodeposition system are inserted into the electrodeposition liquid to form a potential difference in the electrodeposition liquid to achieve electrodeposition. In this embodiment, the anode support 300 is used to support the anode of the electrodeposition system. The anode support 300 is arranged on the electrodeposition liquid container 100 and partially covers the opening of the electrodeposition liquid container 100, so that the anode of the electrodeposition system can be inserted into the electrodeposition liquid through the opening. The anode support 300 can be arranged in the middle of the electrodeposition liquid container 100 to arrange the anode in the middle of the electrodeposition liquid container 100. There can be multiple cathodes in the electrodeposition system, and the multiple cathodes can be divided into multiple groups and respectively arranged on both sides of the anode to perform electrodeposition on multiple cathodes at the same time, thereby improving the efficiency of electrodeposition.

[0038] Specifically, the anode support 300 may be a cover plate disposed on the electrodeposition liquid container 100, which covers a portion of the opening of the electrodeposition liquid container 100. The cover plate may be provided with a plug hole, into which the anode may be inserted, and then inserted into the electrodeposition liquid to work.

[0039] The cathode support device 400 is used to support the cathode 500. The number of cathodes 500 can be one or more, and the present invention does not limit this. When the cathode support device 400 supports multiple cathodes 500, electrodeposition can be performed on multiple cathodes 500 at the same time to improve the efficiency of electrodeposition. The cathode 500 can be a conductive material. For example, the cathode 500 can be a metal material. When a uranium dioxide coating is electrodeposited on the cathode 500 to prepare an irradiation target, the cathode 500 can be an alloy material, such as a zirconium alloy material. The shape of the cathode 500 can be tubular, and the tubular cathode 500 can have a hollow lumen. Of course, the cathode 500 can also be other shapes, and the present invention does not limit this.

[0040] It should be noted that the cathode support device 400 described in the embodiment of the present invention is described as being used to support the cathode in the electrodeposition system for electrodeposition of uranium dioxide, but it can be understood that the structure of the cathode support device 400 described in the embodiment of the present invention is not limited by the polarity of the electrode, and when the structure of the cathode support device 400 is used in other electrodeposition systems, the cathode support device 400 can also be used to support the anode. In other words, the cathode support device 400 can support both the cathode and the anode of the electrodeposition system.

[0041] The number of cathode support devices 400 may be one or more. For example, four cathode support devices 400 may be provided on the electrodeposition liquid container 100, and the present invention is not limited thereto. When multiple cathode support devices 400 are provided, more cathodes 500 may be electrodeposited at the same time, further improving the efficiency of electrodeposition.

[0042] In some embodiments, the cathode support device 400 is configured to control the rotation of the plurality of cathodes 500, that is, when the cathode 500 is supported on the cathode support device 400, the cathode 500 can rotate around an axis outside the cathode 500 under the action of the cathode support device 400. The cathode 500 can be partially or completely immersed in the electrodeposition liquid. In this embodiment, the cathode support device 400 controls the rotation of the plurality of cathodes 500, and the cathode 500 is located in the electrodeposition liquid. The rotation of the plurality of cathodes 500 can increase the disturbance of the electrodeposition liquid, making the concentration distribution in the electrodeposition liquid more uniform and the components uniform, thereby preventing the concentration polarization phenomenon and ensuring the normal progress of the electrodeposition.

[0043] like Figure 3As shown, in some embodiments, in order to further prevent the occurrence of concentration polarization, a magnetic stirring unit 110 may be provided in the electrodeposition container 100, and a magnetic driving unit is provided at the bottom of the heating container 200, and the magnetic driving unit is configured to drive the magnetic stirring unit 110 to rotate by magnetic force. By providing the magnetic stirring unit 110 and driving the magnetic stirring unit 110 to rotate by the magnetic driving unit to stir the electrodeposition liquid, the disturbance of the electrodeposition liquid in the electrodeposition liquid container 100 can be further enhanced, so that the concentration distribution of the electrodeposition liquid in the electrodeposition liquid container 100 is uniform, and the components are uniform, which plays a role in eliminating concentration polarization and ensuring the normal progress of electrodeposition. In addition, the magnetic driving unit is configured to drive the magnetic stirring unit 110 to rotate by magnetic force, which can avoid opening a hole at the bottom of the electrodeposition container, thereby increasing the sealing of the bottom of the electrodeposition container and preventing leakage of the electrodeposition liquid.

[0044] like Figure 3 As shown, in some embodiments, the magnetic stirring part 110 may be circular, and a plurality of blades may be provided around the magnetic stirring part 110 to increase the stirring performance of the magnetic stirring part 110, and the plurality of blades may be evenly distributed around the magnetic stirring part 110 to ensure the smooth rotation of the magnetic stirring part 110. In some embodiments, the magnetic stirring part 110 is made of polytetrafluoroethylene, which is resistant to high temperature and acid and alkali corrosion.

[0045] like Figure 4 As shown, in some embodiments, the cathode support device 400 may include a connector 410 and a rotating assembly 420. Among them, a plurality of cathodes 500 are connected to the connector 410, and the connector 410 is used to connect to a power source to power the cathodes 500. The rotating assembly 420 is connected to the connector 410, and the rotating assembly 420 is used to drive the connector 410 to rotate so as to drive the cathodes 500 to rotate in the electrodeposition solution.

[0046] Specifically, the rotating assembly 420 can be connected to the connecting member 410 and drive the connecting member 410 to rotate. The connecting member 410 can be disc-shaped, and the connecting member 410 can rotate around its own axis under the drive of the rotating assembly 420. In this embodiment, the connecting member 410 keeps the multiple cathodes 500 relatively still and connected together, and the connecting member 410 can drive the multiple cathodes 500 to rotate with the rotation of the connecting member 410, that is, the multiple cathodes 500 rotate around the axis of the connecting member 410. The connecting member 410 can be a conductor, for example, the material of the connecting member 410 can be metal, and the connecting member 410 can also be directly or indirectly electrically connected to a power source, so that the power of the power source is transmitted to the cathode 500 through the connecting member 410.

[0047] In some embodiments, the cathode support device 400 further includes a support tube 430, the support tube 430 is used to support the cathode 500, and the support tube 430 is fixedly connected to the connector 410, so that the cathode 500 can be connected to the connector 410. The number of the support tubes 430 can be the same as the number of the cathodes 500, the number of the support tubes 430 can be multiple, and the multiple support tubes 430 can be evenly distributed along the circumferential direction of the connector 410, so as to achieve uniform electrodeposition on the multiple cathodes 500.

[0048] like Figure 5 and Figure 6 As shown, in some embodiments, the cathode 500 is tubular. The support tube 430 is elastic, and the support tube 430 is configured to be able to contract radially inward to extend into the cathode 500, and support the cathode 500 in the cathode 500 by relying on the radially outward restoring force. The cathode support device 400 provided in this embodiment supports the cathode 500 inside the tubular cathode 500 through the radially outward tension of the support tube 430, so that the support tube 430 supports the cathode 500 from the inside of the tube, so that the outer surface of the cathode 500 can be fully plated with a coating during electrodeposition, thereby improving the utilization efficiency of the cathode 500.

[0049] In this embodiment, the support tube 430 can generate elastic deformation along the radial direction of the support tube 430. Specifically, when the tubular cathode 500 needs to be installed on the support tube 430, the support tube 430 can be elastically deformed inwardly along the radial direction of the support tube 430, and the diameter of the support tube 430 becomes smaller. At this time, the diameter of the support tube can be smaller than the inner diameter of the tubular cathode 500, and the support tube 430 can enter the tube cavity of the cathode 500. After the support tube 430 enters the tube cavity of the cathode 500, the support tube 430 can generate a restoring force in the radial direction of the support tube 430. At this time, the support tube 430 can apply an elastic restoring force in the radial direction to the inner wall of the cathode 500 to support the cathode 500 so that the cathode 500 is fixed on the support tube 430.

[0050] In addition, it should be noted that the support tube 430 in the embodiment of the present invention is a conductor, for example, the support tube 430 may be made of stainless steel, and in other embodiments, the material of the support tube 430 may be other metals or alloys. The electric energy of the power supply can be transmitted to the support tube 430 through the connector 410, and then transmitted to the cathode 500 through the support tube 430, so as to realize the power supply to the cathode 500. In some embodiments, the cathode support device 400 can support the tubular cathode 500 involved in other electrodeposition processes, and the present invention is not limited to this.

[0051] In some embodiments, a plurality of linear notches 431 are provided on the support tube 430, and the linear notches 431 extend along the axial direction of the support tube 430 to one end of the support tube 430. The plurality of linear notches 431 may extend from the middle of the support tube 430 along the axial direction of the support tube 430 to one end of the support tube 430, and the linear notches 431 divide the tube wall of the support tube 430 into a plurality of sub-tube walls 432, and the sub-tube walls 432 may open outward at a certain angle along the radial direction of the support tube 430, and one end of each of the plurality of sub-tube walls 432 is connected to the portion of the support tube 430 that is not divided by the linear notches 431, and the other end of the sub-tube wall 432 forms a free end, and the free end of the sub-tube wall 432 may generate elastic deformation along the radial direction of the support tube 430, so that the support tube 430 can support the cathode 500 inside the tube.

[0052] like Figure 7 As shown, in some embodiments, the plurality of linear notches 431 are evenly distributed along the circumferential direction of the support tube 430. The widths of the plurality of linear notches 431 may be the same, and the plurality of linear notches 431 are evenly distributed along the circumferential direction of the support tube 430, and a plurality of sub-tube walls 432 with even widths may be divided. The sub-tube walls 432 with even widths can generate almost the same elastic restoring force when the deformation amount is the same, so that the cathode 500 is subjected to a more even force, and the cathode 500 is prevented from being damaged. The friction between the support tube 430 and the inner wall of the cathode 500 may also be made more even, so that the fixing effect of the support tube 430 on the cathode 500 is better.

[0053] In some embodiments, the support tube 430 is provided with a protrusion 433, which protrudes from the outer surface of the support tube 430 to increase the friction between the support tube 430 and the cathode 500. The protrusion 433 can be provided at a portion of the support tube 430 that can contact the inner wall of the cathode 500, for example, the protrusion 433 can be provided on the sub-tube wall 432. By providing the protrusion 433, the friction between the support tube 430 and the inner wall of the cathode 500 can be increased, so that the fixation between the support tube 430 and the cathode 500 is more stable. At the same time, the protrusion 433 can also prevent the friction from being too tight, which affects the plugging and unplugging of the cathode 500.

[0054] In some embodiments, the protrusion 433 is an annular protrusion, and the linear notch 431 passes through the annular protrusion. The annular protrusion can be coaxially arranged with the support tube 430. Since the linear notch 431 passes through the annular protrusion, a complete annular protrusion can be divided into multiple sub-protrusions by multiple linear notches 431. The multiple sub-protrusions divided from the same annular protrusion are respectively arranged on different sub-tube walls 432. By providing the annular protrusion, the elastic restoring force on the cathode 500 can be distributed more evenly in the circumferential direction.

[0055] In some embodiments, there are multiple protrusions 433, and the multiple protrusions 433 are evenly arranged along the axial direction of the support tube 430. By evenly arranging the multiple protrusions 433 along the axial direction of the support tube 430, the elastic restoring force on the cathode 500 can be distributed more evenly in the axial direction, and the friction between the support tube 430 and the inner wall of the cathode 500 can be increased, so that the connection between the support tube 430 and the cathode 500 is more stable.

[0056] In some embodiments, a positioning portion 434 is further provided on the support tube 430, and the protrusion 433 is located between the end of the support tube 430 away from the connector 410 and the positioning portion 434. The positioning portion 434 protrudes from the outer surface of the support tube 430, and the outer diameter of the positioning portion 434 is greater than the inner diameter of the cathode 500, which is used to define the installation position of the cathode 500. The positioning portion 434 in this embodiment is located between the connector and the protrusion 433, and the outer diameter of the positioning portion 434 is greater than the inner diameter of the cathode 500. When the support tube 430 is inserted into the cathode 500 to a certain depth, the tube mouth of the cathode 500 can be made to contact the positioning portion 434. The positioning portion 434 limits the axial movement of the support tube 430 along the cathode 500, so that the support tube 430 can no longer be inserted into the cathode 500, thereby controlling the depth of the support tube 430 inserted into the cathode 500, and further controlling the depth of the cathode 500 in the electrodeposition solution by controlling the height of the support tube 430.

[0057] like Figure 8 As shown, in some embodiments, the linear notch 431 passes through the positioning portion 434 and extends to the side of the positioning portion 434 away from the protrusion 433. The linear notch 431 passes through the positioning portion 434, and the positioning portion 434 can be divided into a plurality of sub-positioning portions, and the sub-positioning portions formed by the positioning portion 434 are respectively arranged on different sub-tube walls 432, so that the positioning portion 434 is also elastic. When the cathode 500 needs to be removed from the support tube 430, the elastic positioning portion 434 can be pressed to make the cathode 500 easy to pull out from the support tube 430; at the same time, the linear notch 431 passes through the positioning portion 434 and extends to the side of the positioning portion 434 away from the protrusion 433, which is conducive to adjusting the elasticity of the support tube 430, so that a greater friction force is generated between the support tube 430 and the cathode 500.

[0058] In some embodiments, the support tube 430 is provided with a mounting portion 435, which is disposed at the other end of the support tube 430 away from the linear notch 431. In addition, the connector 410 is provided with a mounting hole, and the mounting portion 435 is inserted and fixed in the mounting hole, so that the support tube 430 is detachably connected to the connector 410 through the mounting portion 435. The mounting portion 435 can be a cylinder formed at one end of the support tube 430, and the diameter of the cylinder matches the diameter of the mounting hole, so that the support tube 430 can be installed on the connector 410.

[0059] like Fig. 9 As shown, a plurality of mounting holes are provided on the connector 410 for connecting a plurality of support tubes 430. For example, 16 support tubes 430 can be connected to the connector 410. With this arrangement, a plurality of cathodes 500 can be installed on one connector 410, so that multiple cathodes 500 can be used for electrodeposition at the same time to improve the efficiency of electrodeposition; at the same time, installing a plurality of cathodes 500 on one connector 410 can improve the stirring effect of the cathode 500 on the electrodeposition liquid. In some embodiments, a plurality of mounting holes can be provided on the connector 410 near the edge, and the plurality of mounting holes are evenly distributed along the circumferential direction of the connector 410.

[0060] like Fig. 9 and Fig.10 As shown, in some embodiments, the cathode support device 400 further includes a mounting plate 440. The mounting plate 440 partially covers the opening of the electrodeposition liquid container 100, thereby covering the opening of the electrodeposition liquid container 100 together with the anode support to prevent the electrodeposition liquid from splashing. At least one rotating assembly 420 is mounted on the mounting plate 440, and the rotating assembly 420 mounted on the mounting plate 440 can drive the connecting member 410 to rotate.

[0061] In some embodiments, the rotating assembly 420 includes a driving motor 421 and a rotating shaft 422. The driving motor 421 is disposed on the mounting plate 440, and a shaft hole is disposed on the mounting plate 440. The rotating shaft 422 passes through the shaft hole and is rotatably connected to the shaft hole. One end of the rotating shaft 422 is fixedly connected to the connecting member 410, and the other end is connected to the driving motor 421. The driving motor 421 is used to drive the rotating shaft 422 to rotate so as to drive the connecting member 410 to rotate.

[0062] like Fig.11 As shown, in some embodiments, a plurality of rotating assemblies 420 are mounted on a mounting plate 440. By mounting a plurality of rotating assemblies 420 on one mounting plate 440, a plurality of cathode groups 500 can be further mounted. For example, two rotating assemblies can be mounted on each mounting plate 440 to improve the electrodeposition efficiency.
