[0025] In the following, exemplary embodiments according to this application will be described with reference to the accompanying drawings. In the specification, non-essential features of the actual embodiments are not described in order to make the description clear and brief. It should be appreciated, however, that many embodiment-specific decisions must be made in order to implement the specific objectives of the developers, such as compliance with those limitations related to the system and business, which can vary from embodiment to embodiment, in the course of developing any such actual embodiments. It should also be appreciated that, although the development work can be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the contents of this application.

[0026] It should also be noted here that, in order to avoid obscuring the present application with unnecessary details, only the device structures and / or processing steps closely related to the scheme according to the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0027] The following disclosure provides several different implementations or examples for carrying out this application. To simplify the disclosure of this application, specific examples of components and methods are described below. Of course, these are merely examples and are not intended to limit this application. In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] Generally, after the nuclide obtained by electrolysis is scraped off the electrode, the nuclide raw material is in powder form. In order to facilitate subsequent recycling, the form of the raw material needs to be changed. The inventors of this application have discovered that forming the powdered nuclide raw material into ingots in a glove box can facilitate the transportation of the raw material, and casting in a glove box can reduce the radioactive risk during the operation.

[0029] Embodiments of this application provide an apparatus for preventing blockage of radioactive material ingots. Figure 1 This illustration shows a schematic diagram of the assembly of various components of an apparatus for preventing blockage of radioactive material ingots according to embodiments of this application. In some embodiments, such as... Figure 1 As shown, it includes: a body 10, a melting assembly 20, a material conveying assembly 70, an ingot forming assembly 30, a cooling assembly 60, a vacuuming assembly 40, and a conveying assembly 50. The material conveying assembly 70 is fixedly connected to the body 10 and is configured to convey radioactive material to the melting assembly 20. The melting assembly 20 is disposed on the body 10 and is fixedly connected to the body 10. Radioactive material is input into the melting assembly 20, where it is transformed into a molten state. The ingot forming assembly 30 is fixedly connected to the body 10, and the molten radioactive material is transferred from the melting assembly 20 to the ingot forming assembly 30. The radioactive material flows out of and into the ingot forming assembly 30, where it is formed into an ingot. The cooling assembly 60 is configured to cool the ingot forming assembly 30. The vacuuming assembly 40 is located on the outside of the main body 10 and is configured to vacuum the melting assembly 20. The conveying assembly 50 is located on the outside of the main body 10 and is configured to transfer the radioactive material from the ingot forming assembly 30 to the conveying assembly 50 after it has been formed into an ingot. The radioactive material is then transported to a predetermined position by the conveying assembly 50. The material conveying assembly 70 is configured to prevent the accumulation of radioactive material so that the radioactive material can enter the melting assembly 20 from the material conveying assembly 70.

[0030] The device for preventing blockage of radioactive material ingots provided in this application isolates the melting, casting, and cooling processes of radioactive material from the outside environment by installing a device 100 for preventing blockage of radioactive material ingots inside a glove box 200, thus preventing radioactive material from being exposed to an environment accessible to operators and ensuring personnel safety. The conveying component 50 is configured to cooperate with the material outlet of the glove box 200 to facilitate the transfer of formed material. The material conveying component 70 is configured to prevent the accumulation of radioactive material and blockage within the material conveying component 70, ensuring smooth material delivery.

[0031] Figure 3 This illustration shows a schematic diagram of a material conveying assembly fixed to a first-layer frame structure according to an embodiment of this application. In some embodiments, such as... Figure 1 and Figure 3 As shown, the body 10 forms a first-layer frame structure 11, a second-layer frame structure 12, and a third-layer frame structure 13, which are arranged sequentially from top to bottom along the spatial direction; the material conveying component 70 is fixed to the first-layer frame structure 11, the melting component 20 is fixed to the second-layer frame structure 12, and the ingot forming component 30 is fixed to the third-layer frame structure 13.

[0032] In some embodiments, the body 10 forms a three-layer frame structure, which correspondingly forms three hollow spaces. The top of the first-layer frame structure 11 is a solid rectangle with an opening in the middle. The size of the opening matches the material feeding port on the upper part of the material conveying component 70, so that the upper part of the material conveying component 70 can be fixedly connected to the top of the first-layer frame structure 11 through the opening. The lower part of the material conveying component 70 extends downward within the first-layer space formed by the first-layer frame structure 11. The bottom of the material conveying component 70 is fixedly connected to the top side of the second-layer frame structure 12, so that the material conveying component 70 extends entirely within the first-layer frame structure 11 and is fixed at both the top and bottom ends, preventing the material conveying component 70 from tilting or shaking and causing material spillage.

[0033] The material outlet at the bottom of the material conveying assembly 70 is configured to be in fluid communication with the melting assembly 20. The bottom of the melting assembly 20 is fixedly connected to the bottom frame of the second-layer frame structure 12. In some embodiments, such as... Figure 1 As shown, the molten component 20 is configured as a vertical cylinder, and a predetermined number of support members (e.g., 4) are formed at the bottom of the circumferential sidewall of the molten component 20. The support members are configured to rest on the bottom edge of the second frame structure 12, so that the molten component 20 extends within the second frame structure 12 and is fixed at the bottom, thereby stabilizing the bottom of the molten component 20 and preventing the molten component 20 from tilting and shaking, which could cause an accident.

[0034] The ingot forming assembly 30 is located at the bottom of the body 10. A part of the ingot forming assembly 30 is located in the space formed by the third frame structure 13, and this part overlaps with the melting assembly 20 in the vertical direction to ensure that the molten material in the melting assembly 20 can fall freely into the ingot forming assembly 30. The rest of the ingot forming assembly 30 extends out of the third frame structure 13.

[0035] The three-layer frame structure of the main body 10 allows the melting component 20 to be placed above the ingot forming component 30, thereby realizing the layout from melting to ingot forming in the vertical direction, saving the horizontal layout space, and allowing sufficient space inside the glove box 200 for the device to be made into ingots.

[0036] Figure 2 This illustration shows a partial structural diagram of a material conveying assembly provided in an embodiment of this application. In some embodiments, such as... Figure 2 As shown, the material conveying assembly 70 is configured to prevent the accumulation of radioactive material so that the radioactive material can enter the melting assembly 20 from the material conveying assembly 70.

[0037] In some embodiments, the components of the material conveying assembly 70 are assembled from top to bottom, and the material is fed into the material conveying assembly 70 from the topmost inlet, allowing the material to fall under its own weight.

[0038] In some embodiments, such as Figure 3 As shown, the material conveying assembly 70 includes a material conveying component 71 and a connecting component 72. The material conveying component 71 is fixedly installed on the first layer frame structure 11, and the material conveying component 71 conveys the material to the melting assembly 20 via the connecting component 72. The connecting component 72 is fixedly connected to the melting assembly 20, and the material conveying component 71 is configured as a chute-shaped structure.

[0039] The material conveyor 71 is configured as a chute-like structure with the upper end 711 and the lower end 713 being vertical and the middle section 712 being inclined. This allows the material to slide down the inclined middle section 712 under its own gravity after being put into the material conveyor 71. This design increases the contact area between the material and the inside of the material conveyor 71, providing a certain buffer resistance for the material to fall, so that the material falls at a uniform speed after being buffered, preventing a large amount of material from falling vertically and causing uneven feeding of the material in the melting component 20. In addition, the upper end 711 is configured as a vertical shape, which makes it easy to fix and connect to the top of the first layer frame structure 11. This also makes the cross section of the material feeding inlet horizontal and smooth, which facilitates the feeding of the material and the opening and closing of the material feeding inlet.

[0040] In some embodiments, such as Figure 2As shown, the material conveying assembly 70 also includes a vibrating element 73. One end of the vibrating element 73 is fixedly connected to the material conveying component 71, and the other end of the vibrating element 73 is fixedly connected to the connecting component 72. The vibrating element 73 is configured to vibrate during the process of radioactive material being transmitted from the material conveying component 71 through it to the connecting component 72, so as to avoid the accumulation of radioactive material.

[0041] In some embodiments, the lower end 713 of the material conveyor 71 is fixedly connected to the vibrator 73. The lower end 713 is set vertically to facilitate fluid communication with the vibrator 73. Since the middle section 712 is set inclined, the contact resistance between the powdery material and the material conveyor 71 increases, which may cause the material conveying assembly 70 to accumulate in the inclined middle section 712. Therefore, the vibrator 73 is set at the bottom of the material conveyor 71 so that it vibrates during the material feeding process. This can drive the material conveyor 71 to vibrate and shake off the powdery material accumulated on the inclined middle section 712, thus avoiding the internal blockage of the material conveying assembly 70. The vibrator 73 works together with the chute-shaped material conveyor 71 to prevent the material from falling vertically in large quantities during feeding, which would cause uneven distribution of the material in the melting assembly 20. It can also prevent the internal accumulation and blockage that may be caused by the uniform falling of the material in the material conveyor 71.

[0042] The lower part of the vibrating element 73 is fixedly connected to one end of the connecting element 72, and the other end of the connecting element 72 is in fluid communication with the melting component 20, so that the material can smoothly enter the melting component 20 from the material conveying element 71.

[0043] In some embodiments, such as Figure 2 As shown, the material conveying assembly 70 also includes a passage switch control component 74, which is fixedly connected to the connector 72 and controls the switching state between the connector 72 and the melting assembly 20.

[0044] The access switch control component 74 is fixedly connected to the connector 72. In some embodiments, the access switch control component 74 is an ultra-high pneumatic slide valve, which realizes the opening and closing between the connector 72 and the melting component 20, and controls the amount of material fed in.

[0045] Figure 7 This illustration shows a cross-sectional schematic diagram of an ingot forming assembly provided in an embodiment of this application. In some embodiments, such as... Figure 1 and Figure 7 As shown, the ingot forming assembly 30 includes an ingot forming component 32, a rotating support component 33, and a driving component. The ingot forming component 32 forms multiple molten material receiving spaces 31. Molten radioactive material flows out from the melting assembly 20 and into the multiple molten material receiving spaces 31. The rotating support component 33 is configured to support the ingot forming component 32, and the driving component is configured to drive the rotating support component 33 to rotate. The rotating support component 33 is configured to drive the ingot forming component 32 to rotate.

[0046] A portion of the ingot forming assembly 30 is configured to overlap with the melting assembly 20 in the vertical direction. The size of the molten material outlet formed by the melting assembly 20 matches the size of the molten material receiving space 31 on the ingot forming assembly 30. The molten material receiving spaces 31 on the ingot forming assembly are of equal size, so that the molten material can fall accurately into the molten material receiving space 31, preventing waste caused by material spillage.

[0047] In some embodiments, the rotating support 33 is configured as a disc, and the ingot forming parts 32 are uniformly arranged circumferentially above the rotating support 33. When the amount of molten material received by the molten material receiving space 31 reaches a predetermined amount, the driving member drives the rotating support 33 to rotate the ingot forming parts 32 around the axis, so that the position of the molten material receiving space 31 in the ingot forming parts 32 changes relative to the molten material outlet, so that the adjacent uncast molten material receiving space 31 is aligned with the molten material outlet for the next casting.

[0048] In some embodiments, the ingot forming assembly 30 further includes a weighing element disposed below the drive element, configured to determine the weight of the incoming molten material received by the ingot forming assembly 32.

[0049] The weighing component monitors the weight of the molten material inside the ingot 32. When the weight of the molten material inside the ingot reaches a predetermined value, the driving component drives the rotating support component 33 to rotate the ingot 32, so that the adjacent uncast ingots 32 are aligned with the molten material outlet for the next casting. This allows for precise control of the weight of the molten material in each molten material receiving space 31, ensuring that the formed material is of uniform size and preventing excessive casting of molten material in a single ingot, which would cause molten material to overflow and be wasted.

[0050] Figure 8 This illustration shows a schematic diagram of a device for preventing blockage of radioactive material ingots, provided by an embodiment of this application, disposed within a glove box. In some embodiments, such as... Figures 7-8 As shown, the cooling assembly 60 includes a coolant supply 61 and a coolant circuit 62. The coolant supply 61 supplies coolant to the coolant circuit 62, and the coolant circuit 62 supplies coolant to the ingot forming assembly 30 to cool the ingot forming assembly 30 during the ingot forming process of molten radioactive material. The coolant is also configured to return the used coolant to the coolant supply 61 through the coolant circuit 62.

[0051] A coolant supply 61 is disposed outside the glove box 200, and a coolant circuit 62 is disposed inside the glove box 200. The coolant circuit 62 is connected to the coolant supply 61 and extends into the glove box 200. In some embodiments, such as... Figure 7As shown, a portion of the coolant circuit 62 is arranged along the axis of the ingot forming assembly 30, and other portions of the coolant circuit 62 extend horizontally to the bottom of the ingot forming member 32. The coolant provided by the coolant supply member 61 circulates to cool the molten material in the molten material receiving space 31. The used coolant returns to the coolant supply member 61 through the coolant circuit 62, realizing heat exchange and dilution, thereby ensuring that the ingot forming member 32 is continuously cooled and improving the ingot forming rate.

[0052] In some embodiments, a cooling gap exists inside the ingot forming assembly 30. The cooling gap forms a space for coolant flow around the ingot forming part 32. The coolant circuit 62 provides coolant to the cooling gap so that the ingot forming part 32 is cooled.

[0053] In some embodiments, the rotating support 33 is configured to have a predetermined thickness in the vertical direction, and the space within the predetermined thickness is a hollow disk shape. Uniformly distributed grooves are formed on the circumferential upper part of the rotating support 33 to accommodate the ingot 32. The ingot 32 is configured as a cylindrical container with an open top. The outer diameter of the ingot 32 is set slightly smaller than the inner diameter of the groove, facilitating the detachment of the ingot 32 from the rotating support 33 and preventing the ingot 32 from being too tightly engaged with the groove, thus affecting the transfer of the product ingot.

[0054] In some embodiments, the depth of the molten material receiving space 31 within the ingot 32 is greater than the depth of the groove, so that the upper opening of the ingot 32 can be higher than a predetermined distance above the groove, leaving space for gripping, so that the operator can take the ingot 32 out of the groove of the rotating support 33 from the glove opening 210.

[0055] In some embodiments, the sidewall opening edge of the ingot 32 extends radially away from the center to form an eave of predetermined width, preventing the ingot 32 from slipping from its free end during the process of the operator picking it up from the glove opening 210. Simultaneously, the bottom of the ingot 32 contacts the bottom of the tank, and the coolant circuit 62 introduces coolant into the hollow disc-shaped space within the rotating support 33. This enables effective heat exchange in the ingot 32, reduces the impact of air gaps on heat exchange and cooling, improves the heat transfer coefficient, and increases cooling efficiency.

[0056] Figure 6 This illustration shows a partial structural diagram of a spindle provided in an embodiment of this application. In some embodiments, such as... Figure 6 As shown, the ingot 32 includes a two-lobed structure 321, with a micropore formed in the middle of the two-lobed structure 321, and the two-lobed structure 321 is fixedly mounted on the rotating support 33.

[0057] In some embodiments, the ingot 32 is configured as a two-part structure 321 instead of a one-piece groove structure. The two-part structure 321 forms a slit with micropores at the bottom of the ingot 32, allowing air bubbles carried during the casting process to be discharged from the micropores during cooling, preventing air bubbles from being present inside the ingot after it is formed. The micropores at the bottom of the ingot 32 also prevent the formation of a vacuum between the molten ingot and the ingot 32, balancing the pressure inside and outside the ingot 32. In some embodiments, the radioactive material is uranium, and the thermodynamic and physical properties of the uranium ingot metal and the mold metal formed by casting are quite different. The two-part design combined with water cooling can effectively ensure the demolding of the uranium ingot and improve the casting efficiency.

[0058] In some embodiments, such as Figure 1 As shown, the conveying assembly 50 is arranged parallel to the body 10 and extends in the direction away from the body 10 from the ingot forming assembly 30.

[0059] In some embodiments, such as Figure 1 and Figure 8 As shown, the conveying assembly 50 is arranged side by side with the main body 10 instead of extending directly from inside the frame of the main body 10, and the remaining part of the ingot forming assembly 30 extends towards the glove opening 210 on the side of the glove box 200 to the outside of the third frame structure 13. This arrangement is to facilitate the conveying assembly 50 and the ingot forming assembly 30 to be close to the glove opening 210, so that the operator can easily take the formed uranium ingot from the ingot forming assembly 30 through the glove opening 210 and place it on the conveying assembly 50, so that the uranium ingot is transferred to the next process. If the conveying assembly 50 is arranged to extend from the middle of the frame inside the main body 10 to the material outlet of the glove box 200, the conveying assembly 50 will be far away from the glove opening 210, which will create an obstacle for the operator to transfer the uranium ingot.

[0060] Figure 4 This illustration shows a cross-sectional view of the upper part of the housing of a molten assembly provided in an embodiment of this application. In some embodiments, such as... Figure 1 and Figure 4 As shown, the melting assembly 20 includes a housing 22, a melting element 21 disposed inside the housing 22, the housing 22 being fixedly connected to the bottom frame of the second frame structure 12, and the housing 22 forming an opening that is in fluid communication with the material conveying assembly 70. Radioactive material is transported via the material conveying assembly 70 and enters the melting element 21 through the opening. The vacuum assembly 40 evacuates the housing 22.

[0061] In some embodiments, such as Figure 4As shown, the second-layer frame structure 12 is fixedly connected to the support formed by the shell 22, and the support formed by the shell 22 is symmetrically arranged on the outer periphery of the lower part of the shell 22 to maintain the stability of the entire molten assembly 20. An opening is formed at the upper part of the shell 22 for feeding material into the molten component 21 inside the shell 22 through the opening, and a vacuum is drawn inside the shell 22 by the vacuum assembly 40 to remove gaseous impurities inside the shell 22 and prevent the uranium raw material from reacting with air after heating, which would reduce the purity of the raw material.

[0062] In some embodiments, such as Figure 3 As shown, the ingot forming position is set at the glove opening 210 position of the glove box 200 so that the operator can transfer the product ingot from the ingot forming assembly 30 to the conveying assembly 50 through the glove opening 210.

[0063] Positioning the conveyor assembly 50 near the glove opening 210 allows operators to easily remove the demolded uranium ingot from the ingot forming assembly 30 and place it on the conveyor assembly 50, reducing the distance the operator needs to reach into the glove box 200, lowering operational risks, and improving operational efficiency.

[0064] Figure 5 This illustration shows a partial structural diagram of a molten element opening and closing member provided in an embodiment of this application. In some embodiments, such as... Figure 4 and Figure 5 As shown, the molten metal opening and closing component 23 includes a sliding structure 231, a furnace cover 232, and a driving structure 233. The sliding structure 231 is slidably connected to the furnace cover 232 and is fixed to the housing 22. The driving structure 233 is fixedly connected to the sliding structure 231 and drives the furnace cover 232 to slide along the sliding structure 231 to change the opening and closing state of the furnace cover 232.

[0065] In some embodiments, the sidewall of the shell 22 is configured as a vertical cylinder, the molten element 21 is disposed vertically in the middle of the shell 22 with its opening facing upward, the top and bottom of the shell 22 are configured as arc surfaces convex in opposite directions, the molten element opening and closing element 23 is disposed at the cross section at the junction of the top of the shell 22 and the sidewall, the molten element opening and closing element 23 is fixedly connected to the sidewall of the shell 22, and the plane of the molten element opening and closing element 23 is parallel to the circular cross section of the shell 22, so that the furnace cover 232 can be aligned with and tightly attached to the opening of the molten element 21 after it is closed.

[0066] The furnace cover 232 is a two-semi-circular structure, which is arranged opposite each other to form a circle. The furnace cover 232 can slide on the sliding structure 231. In some embodiments, the driving structure 233 is a cylinder. The driving structure 233 can drive the furnace cover 232 to move away from the driving structure 233. That is to say, the molten part opening and closing part 23 adopts a translational opening structure. The driving structure 233 drives the furnace cover 232 to move in opposite directions, so that the two semi-circular furnace covers 232 can merge into a circle, thereby closing the opening of the molten part 21. The driving structure 233 can also drive the furnace cover 232 to move in the opposite direction, so that the merged circle becomes two separate semi-circles, thereby opening the opening of the molten part 21.

[0067] In some embodiments, the furnace cover 232 is made of high-temperature resistant and stable materials such as quartz or tungsten-molybdenum high-temperature alloy. The radius of the furnace cover 232 is set to 262mm and the thickness is set to 130mm. The inner lining of the furnace cover 232 is made of ceramic fiber cotton, which enables the furnace cover 232 to achieve low thermal conductivity and high refractoriness.

[0068] In some embodiments, such as Figure 4 and Figure 5 As shown, the sliding structure 231 includes a slide rail 2311 and a slider 2312.
