[0036] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.
[0037] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.
[0038] 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.
[0039] The inventors of this application discovered that after drying the remaining sample after dissolution in the dissolution device, condensation remains on the inner surface of the cover plate. Even by extending the drying time, it is difficult to completely dry the inner surface of the cover plate. This poses a radioactive contamination problem when the cover plate is opened.
[0040] The inventors of this application further discovered that this is because when drying the remaining sample after dissolution, the cover plate is located in the external environment. Since the cover plate is usually made of metal, which conducts heat quickly, the temperature of the cover plate is low. This results in condensation remaining on the inner surface of the cover plate after drying.
[0041] To address the aforementioned issues, this application provides a radioactive material dissolution system that avoids condensation residue forming due to the low temperature of the cover plate during the drying of the remaining sample after dissolution.
[0042] See Figure 1 , Figure 2 as well as Figure 13 This application provides a radioactive material dissolution system with a drying function, comprising: a dissolution device 30, a drying assembly (not shown), a cover plate 1100, and a heating assembly 1150. The dissolution device 30 is configured to form a dissolution tank 311 with a top opening. The dissolution tank 311 is configured to receive a liquid solution for dissolving radioactive material and to provide a dissolution space for a radioactive sample containing radioactive material. The drying assembly is used to dry the radioactive sample within the dissolution tank 311 after dissolution. The cover plate 1100 is used to seal the top opening of the dissolution tank 311. The heating assembly 1150 is disposed on the cover plate 1100 and is used to heat the cover plate 1100.
[0043] The embodiments of this application, by setting up a heating component 1150, can heat the cover plate 1100 when the radioactive sample is dried using the drying component, thereby increasing the temperature of the cover plate 1100 and preventing the formation of condensate residue due to the low temperature of the cover plate 1100 during the drying of the radioactive sample, thus avoiding radioactive contamination problems.
[0044] In some embodiments, the drying component may be dried using electric heating.
[0045] See Figure 2 , Figure 6 and Figure 7 In some embodiments, the heating assembly 1150 may include: a heating element 1151, a heat-conducting element 1152, a heat-insulating element 1153, and a protective shell 1154. The heating element 1151 is used to provide heat, the heat-conducting element 1152 is thermally connected to the cover plate 1100 to conduct the heat provided by the heating element 1151 to the cover plate 1100, the heat-insulating element 1153 is disposed on the outside of the heat-conducting element 1152 to insulate the heat-conducting element 1152, and the protective shell 1154 is disposed on the outside of the heat-insulating element 1153 to protect the heat-insulating element 1153.
[0046] In such an embodiment, the heating component 1150 can transfer heat to the cover plate 1100 through the heat-conducting element 1152 and can reduce heat loss. At the same time, the protective shell 1154 can also protect the heating component 1151, the heat-conducting element 1152, and the heat-insulating element 1153.
[0047] The heating element 1151 may be, for example, an electric heating rod. The material of the heat-conducting element 1152 may be, for example, graphite. An opening 11521 may be formed on the heat-conducting element 1152, and the heating element 1151 is embedded in the opening 11521.
[0048] In some embodiments, the heating assembly 1150 may further include a temperature sensing element disposed within the heat-conducting element 1152 for detecting the temperature of the heat-conducting element 1152.
[0049] In some embodiments, the radioactive material dissolution system may further include two connecting side plates 1160 disposed opposite each other, the two connecting side plates 1160 being connected to both ends of the cover plate 1100. A heating assembly 1150 may be located between the two connecting side plates 1160.
[0050] In some embodiments, see Figure 3 and Figure 8 The radioactive material dissolution system may also include a loading structure 20 and a hoisting device 10. The loading structure 20 is used to load radioactive material. The hoisting device 10 is configured to hoist the loading structure 20 onto the cover plate 1100.
[0051] In some embodiments, the hoisting device 10 includes: a hoisting part 120, a drive assembly 130, and an installation assembly 140. The hoisting part 120 is used to hoist the loading structure 20; the drive assembly 130 is used to drive the hoisting part 120 to move so as to connect or disconnect from the loading structure 20 and to drive the loading structure 20 to move up and down; the installation assembly 140 is used to detachably install the drive assembly 130 as a whole onto the cover plate 1100.
[0052] The hoisting device 10 provided in the embodiments of this application uses the mounting assembly 140 to detachably mount the drive assembly 130 onto the cover plate 1100. When the drive assembly 130 fails, the drive assembly 130 can be completely removed from the cover plate 1100, which is relatively convenient.
[0053] In some embodiments, the mounting assembly 140 may include a first mounting plate 141, which is detachably connected to the cover plate 1100. The first mounting plate 141 may be located above the heating assembly 1150.
[0054] In some embodiments, the first mounting plate 141 is detachably connected to the two connecting side plates 1160. Specifically, mounting blocks can be provided on two opposing surfaces of the two connecting side plates 1160, with mounting holes formed on the mounting blocks. Correspondingly, mounting holes are formed on the first mounting plate 141, and the first mounting plate 141 is detachably connected to the two connecting side plates 1160 by fasteners passing through the mounting holes.
[0055] Fasteners can be bolts, for example. When it is necessary to remove the mounting assembly 140, drive assembly 130 and lifting part 120 as a whole from the cover plate 1100, simply remove the bolts to remove them as a whole.
[0056] In some embodiments, the radioactive material dissolution system is entirely housed within a glove box. The radioactive material dissolution system may also include a support (not shown). The support is disposed within the glove box. A cover 1100 is retractably mounted on the support.
[0057] See Figure 4 In some embodiments, the radioactive material dissolution system may also include two upright plates 1170, each upright plate 1170 being connected to a connecting side plate 1160. The upright plates 1170 are vertically and vertically mounted on the support to enable the overall movement of the hoisting device 10, the heating assembly 1150, and the cover plate 1100.
[0058] In some embodiments, the connecting side plate 1160 and the upright plate 1170 can be a single piece to increase overall strength. The connecting side plate 1160 can be welded to the cover plate 1100. The two connecting side plates 1160, the two upright plates 1170, and the cover plate 1100 can be referred to as the cover assembly 110.
[0059] In some embodiments, the drive assembly 130 may include a rotating shaft 131 and a rotating drive unit 132. The rotating shaft 131 passes through the cover plate 1100 and is connected to the lifting part 120 to drive the lifting part 120 to rotate. The rotating drive unit 132 is used to drive the rotating shaft 131 to rotate. The rotating drive unit 132 is disposed on the first mounting plate 141. The mounting assembly 140 may further include a sealing assembly 142, which is used to dynamically seal the rotating shaft 131 to the cover plate 1100. By providing the sealing assembly 142, the dissolving liquid (i.e., the liquid containing radioactive material) in the dissolving device can be prevented from diffusing into the glove box.
[0060] In the embodiments of this application, the lifting part 120 may have a non-circular structure, such as an elliptical shape. The loading structure 20 is also provided with a lifting mating part, the shape of which is adapted to the shape of the lifting part 120. When the rotation drive part 132 drives the rotation shaft 131 to rotate the lifting part 120 in the lifting mating part, the lifting part 120 can be engaged or disengaged from the lifting mating part, thereby connecting or disengaging the lifting part 120 from the loading structure 20. The engagement method between the lifting part 120 and the lifting mating part may be, for example, a snap-fit engagement.
[0061] The heat insulation element 1153 provided in the heating component 1150 can also reduce the adverse effects of the heat from the heating component 1151 on the sealing component 142.
[0062] In some embodiments, the rotation drive unit 132 may be a motor.
[0063] See Figure 1 In some embodiments, the first mounting plate 141 is provided with a first through hole 1411 for the rotation shaft 131 to pass through, see [reference]. Figure 4 The cover plate 1100 is provided with a cover plate through hole 111 for the rotation shaft 131 to pass through. See also Figure 3 The sealing assembly 142 includes a sleeve 1421 and a sealing cap 1422. The sleeve 1421 is disposed on the first mounting plate 141. The rotating shaft 131 passes through the first through hole 1411, the sleeve 1421 and the cover plate through hole 111 in sequence and extends to the bottom of the cover plate 1100. The sealing cap 1422 is disposed on the sleeve 1421 and is used to seal the gap between the sleeve 1421 and the cover plate through hole 111.
[0064] The size of the hoisting part 120 is smaller than the size of the through hole 111 in the cover plate. Since the first mounting plate 141, sleeve 1421 and sealing cover 1422 are connected to the first mounting plate 141, when disassembling the rotating shaft 131 and the rotating drive part 132 from the cover plate 1100, these parts can be removed as a whole by separating the first mounting plate 141 from the cover plate 1100, which facilitates operation inside the glove box.
[0065] In this embodiment, after the first mounting plate 141 is disassembled from the connecting side plate 1160, lifting the first mounting plate 141 upwards separates the entire assembly, including the sealing component 142, the lifting part 120, the rotating shaft 131, and the rotating drive part 132, from the cover plate 1100. During assembly, as the first mounting plate 141 is placed from top to bottom on the two connecting side plates 1160, the lifting part 120 and the rotating shaft 131 enter the through hole 111 of the cover plate. When the first mounting plate 141 abuts against the two connecting side plates 1160, the sealing cap 1422 presses against the periphery of the through hole 111 of the cover plate, sealing the gap between the sleeve 1421 and the through hole 111. Therefore, the embodiments of this application, through a special design of the sealing component, make the assembly and disassembly of the lifting device 10 very convenient.
[0066] In some embodiments, the surface of the cover plate 1100 facing the first mounting plate 141 may have a recess 112, and the sealing assembly 142 further includes a first sealing member 1423 disposed in the recess 112. When the first mounting plate 141 is detachably connected to the cover plate 1100, the sealing cover 1422 at least partially enters the recess 112 and seals with the first sealing member 1423 to increase the sealing effect. The first sealing member 1423 may be an elastic sealing ring.
[0067] In some embodiments, see Figure 7The sealing cover 1422 may include a sealing cover body 14221 and a sealing cap 14222. When the first mounting plate 141 is detachably connected to the two connecting side plates 1160, the bottom of the sealing cap 14222 enters the recess 112 and presses against the first sealing member 1423. The sealing cover body 14221 is embedded in the through hole 111 of the cover plate. This arrangement can further improve the sealing effect of the sealing cover 1422 and prevent the dissolving liquid from entering above the cover plate 1100.
[0068] In related technologies, dynamic sealing of the rotating shaft 131 is achieved using a sealing gasket and a rubber ring disposed within a groove in the sealing gasket. To facilitate better dissolution of radioactive materials, a drive assembly 130 can be used to move the loading structure 20 up and down within the dissolution device. The inventors of this application have discovered that during the upward and downward movement of the rotating shaft 131, the rubber ring sometimes detaches from the groove in the sealing gasket and enters the gap between the rotating shaft 131 and the first through hole 1411, jamming the rotating shaft 131 and preventing it from rotating or moving up and down.
[0069] To prevent the rubber ring from dislodging from the groove of the sealing gasket and jamming the rotating shaft 131, in some embodiments, see [reference needed]. Figure 3 and Figure 7 The sealing assembly 142 further includes a flexible sealing gasket 1424 and a clamping member 1425. The flexible sealing gasket 1424 is sleeved on the rotating shaft 131, and the clamping member 1425 is used to press the flexible sealing gasket 1424 against the first mounting plate 141 along the axial direction of the rotating shaft 131, thereby dynamically sealing the rotating shaft 131 with the first through hole 1411. This sealing method can achieve dynamic sealing of the rotating shaft 131 without causing the rotating shaft 131 to jam. In some embodiments, the clamping member 1425 may be, for example, a stainless steel gasket. In some embodiments, the flexible sealing gasket 1424 may be a rubber gasket.
[0070] In some embodiments, the flexible sealing gasket 1424 may include two flexible semi-circular gaskets that are tightly fitted with the rotating shaft 131. The flexible sealing gasket 1424 is then fixed to the upper part of the first mounting plate 141 using a clamping member 1425 for easy assembly.
[0071] In some embodiments, sleeve 1421 can be connected to first mounting plate 141 via flange 1427 and bolts 1426. Clamping member 1425 can be connected to first mounting plate 141 via bolts 1426.
[0072] In some embodiments, the mounting assembly 140 may include a second mounting plate 143 and a sliding mounting plate 144. The second mounting plate 143 is connected to the first mounting plate 141, and the sliding mounting plate 144 is slidably connected to the second mounting plate 143. A rotation drive unit 132 is disposed on the sliding mounting plate 144. The drive assembly 130 may further include a lifting drive unit 134 mounted on the second mounting plate 143 for driving the sliding mounting plate 144 to move up and down, thereby driving the hoisting unit 120 to move up and down.
[0073] See Figure 3 In some embodiments, the mounting assembly 140 may further include a first base plate 1412, two opposing first side plates 1413, and a first top plate 1414. The first side plates 1413 are disposed between the first base plate 1412 and the first top plate 1414. The two first side plates 1413 are respectively fixedly connected to the sliding mounting plate 144. A rotation drive unit 132 is disposed on the first top plate 1414. The drive assembly 130 may further include a coupling 133, through which a rotating shaft 131 is connected to the rotation drive unit 132. The coupling 133 is disposed between the first base plate 1412 and the first top plate 1414, and the rotating shaft 131 passes downward through the first base plate 1412.
[0074] With the above configuration, the lifting drive unit 134 can drive the rotation drive unit 132 and the hoisting unit 120 to move up and down. The second mounting plate 143 can be provided with a slide rail 1431. The lifting drive unit 134 can drive the sliding mounting plate 144 to move up and down on the slide rail 1431 through the lead screw 135, thereby driving the loading structure 20 to enter or leave the melting device.
[0075] In some embodiments, see Figure 1 The second mounting plate 143 may also be provided with multiple switches 1341. Each switch 1341 includes a light emitting part and a light receiving part arranged opposite to each other. The sliding mounting plate 144 is also provided with a stop 1441. Each switch 1341 includes multiple sets of light sources and receivers. When the sliding mounting plate 144 moves up and down until the stop 1441 can be located between the light emitting part and the light receiving part of the switch 1341, the switch 1341 sends an electrical signal to indicate that the sliding mounting plate 144 has reached a preset height.
[0076] In some embodiments, the drive assembly 130 may further include a plurality of switches 1321 disposed on the first base plate 1412 for instructing the rotating shaft 131 to rotate to a preset angle.
[0077] In some embodiments, see Figure 6The mounting assembly 140 may also include two symmetrically arranged first reinforcing plates 1415, which are disposed on the side of the sliding mounting plate 144 facing the second mounting plate 143 and serve to reinforce the sliding mounting plate 144.
[0078] In some embodiments, see Figure 1 and Figure 5 The mounting assembly 140 also includes two third mounting pieces 145, which are symmetrically mounted on the first mounting plate 141. The drive assembly 130 also includes multiple power connectors and two electrical connectors 136, each of which is disposed on a third mounting piece 145 for quick-release connection with multiple power connectors and external power cords.
[0079] The electrical connector 136 may be provided with multiple electrical connection interfaces 1361, through which the external power cord is quickly connected to the power connector. Because the electrical connector 136 is quickly connected to the external power cord, and the power connector of the electrical device located on the cover plate 1100 can also be quickly connected to the electrical connector 136, the installation component 140, the drive component 130, and the electrical connector 136 can be removed as a whole when disassembling the drive assembly 130, which is quite convenient.
[0080] In some embodiments, the power connectors of the heating element 1151 and the temperature measuring element of the heating assembly 1150 can be quickly connected to the electrical connector 136. When it is necessary to disassemble the drive assembly 130, the power connectors of the heating element 1151 and the temperature measuring element can be disconnected from the electrical connector 136, which is convenient for operation.
[0081] The embodiments of this application arrange the two third mounting parts 145 symmetrically, so that no eccentric movement occurs when the drive assembly 130 rotates or moves up and down, thereby not affecting the sealing effect of the cover plate 1100.
[0082] See Figure 5 In this embodiment, each third mounting component 145 may include a second base plate 1451, a second side plate 1452, a second top plate 1453, a third side plate 1454, and two mating plates. The second base plate 1451 is fixedly connected to the first mounting plate 141. The two ends of the second side plate 1452 are respectively connected to the ends of the second base plate 1451 and the top plate 1453 near the rotation shaft 131. The third side plate 1454 is connected to the end of the second top plate 1453 away from the rotation shaft 131. Two mating plates are disposed on both sides of the third side plate 1454, forming a slot together with the third side plate 1454 for inserting the power connector 136. The mating plates are also provided with abutting members 1456 for abutting the power connector 136, thereby fixing the power connector 136 to the third mounting component 145.
[0083] In some embodiments, the third mounting member 145 may further include a second reinforcing plate 1455, which is connected to the second base plate 1451, the second side plate 1452, and the second top plate 1453, and is perpendicular to the second base plate 1451, the second side plate 1452, and the second top plate 1453. Since the electrical connector 136 has a certain self-weight, the second reinforcing plate 1455 can improve the mechanical strength of the entire third mounting member 145.
[0084] In some embodiments, the radioactive sample is a radioactive plate-shaped sample with multiple through holes in which radioactive material is collected. The loading structure 20 is used to place multiple radioactive plate-shaped samples into a dissolving tank 311, so that the radioactive material can be dissolved using the liquid in the dissolving tank 311. The liquid containing the dissolved radioactive material can be referred to as the dissolving solution. The radioactive plate-shaped sample can be, for example, a honeycomb plate.
[0085] In some embodiments, the loading structure 20 includes a body 210 and a stop 220. The body 210 is configured to form a receiving cavity 211 with a side opening 2151. The receiving cavity 211 is used to place a plurality of radioactive plate-shaped samples, which are stacked in the receiving cavity 211 along the height direction of the receiving cavity 211. The receiving cavity 211 has a plurality of liquid flow holes 212 to allow the liquid in the dissolving device to enter the receiving cavity 211 and flow through the plurality of through holes of the radioactive plate-shaped samples. The stop 220 is detachably disposed at the side opening 2151 of the receiving cavity 211 to prevent the radioactive plate-shaped samples from being removed from the receiving cavity 211.
[0086] In related technologies, to simultaneously dissolve multiple radioactive plate-shaped samples and ensure that the liquid material fully enters the through-holes of the samples to guarantee complete dissolution of the collected radioactive material, the loading structure typically employs multiple layers of containment cavities, with one radioactive plate-shaped sample placed in each layer. The inventors of this application have discovered that due to the limited space in the dissolution device, the height of the loading structure is usually also limited. If the height of each containment cavity is set to be only slightly greater than the height of the radioactive plate-shaped sample, the operation becomes difficult each time a sample is placed. Conversely, if the height of each containment cavity is set too high, the number of containment cavities decreases, resulting in a smaller number of radioactive plate-shaped samples processed each time.
[0087] The radioactive plate sample loading structure 20 provided in the embodiments of this application has only one receiving cavity 211, which facilitates the stacking of multiple radioactive plate samples along the height direction of the receiving cavity 211, reducing the difficulty of loading the radioactive plate samples. Furthermore, the inventors of this application have discovered that stacking multiple radioactive plate samples along the height direction of the receiving cavity 211, rather than placing them separately in a dissolution tank, also ensures that the radioactive material collected by the radioactive plate samples is completely dissolved. In addition, since there is no need to set up multiple receiving cavities, the partitions between adjacent receiving cavities are omitted, greatly reducing the overall weight of the loading structure 20.
[0088] In some embodiments, the height of the receiving cavity 211 can be determined based on the height of each radioactive plate sample and the content of radioactive material collected therein. The inventors of this application can determine the mass or content of radioactive material within the loading structure 20 at a critical state through critical calculations. The height of the receiving cavity 211 can be adjusted based on the calculated mass or content of radioactive material to regulate the number of radioactive plate samples that can be loaded within the receiving cavity 211, ensuring that the mass or content of radioactive material within the loading structure 20 does not exceed half of the critical amount.
[0089] The main body 210 also includes a hoisting assembly 217, see [link / reference] Figure 11 and Figure 12 The hoisting engagement part 217 is used to cooperate with the hoisting part 120 of the hoisting device 10, so as to hoist the main body 210 by utilizing the cooperation between the hoisting part 120 and the hoisting engagement part 217.
[0090] See Figure 8 and Figure 9 In some embodiments, the main body 210 may include two layers of grid 213, two first side plates 214 disposed opposite to both sides of the two layers of grid 213, and two second side plates 215 disposed opposite to the other two sides of the two layers of grid 213. Each second side plate 215 connects to two first side plates 214. The two first side plates 214, the two second side plates 215, and the two layers of grid 213 together form a receiving cavity 211. The grid 213 forms a plurality of fluid flow holes 212. A side opening 2151 is formed on a second side plate 215 and is located between the two layers of grid 213. The second side plate 215 forming the side opening 2151 is provided with a slot 2153, and a stop member 220 is detachably inserted into the slot 2153.
[0091] The embodiments of this application, by configuring the main body 210 to include two layers of grids 213, not only increase the effective flow area of the liquid flow hole 212, but also help to reduce the weight of the main body 210; by providing a side opening 2151 in the second side plate 215, it is convenient to put multiple radioactive plate-shaped samples into the receiving cavity 211 in sequence; by providing a slot 2153 in the second side plate 215 and providing a stop 220, which can be detachably inserted into the slot 2153, it is possible to prevent the radioactive plate-shaped samples from being moved out of the receiving cavity 211.
[0092] In some embodiments, a slot 2153 is formed inside the second side plate 215. In some embodiments, the second side plate 215 includes a first plate body located above the side opening 2151 and a second plate body located below the side opening 2151. The slot 2153 is formed inside the first plate body to avoid interference with the radioactive plate-shaped sample. When the stop 220 is inserted into the slot 2153, the lower end of the stop 220 is located inside the second plate body, thereby reducing the wobbling of the stop 220.
[0093] In some embodiments, the main body 210 may further include a slot mating member 2152 disposed on the inner side of the first plate body, forming a slot 2153 together with the first plate body.
[0094] In some embodiments, the stop 220 may also have a disassembly hole 222, and the first plate may also have a clearance groove. After inserting a rod through the clearance groove into the disassembly hole 222, moving the rod upwards allows the stop 220 to be removed from the slot 2153. The slot mating member 2152 has a recessed position facing the disassembly hole 222 to facilitate the rod passing through the disassembly hole 222.
[0095] See Figure 8 In some embodiments, the connection between the first side plate 214 and the second side plate 215 can be rounded. The gap between the loading structure 20 and the dissolving tank 311 of the dissolving device 30 is small, making it difficult for the loading structure 20 to enter or exit, and it may get stuck on the tank wall of the dissolving tank 311. The inventors of this application have discovered that by setting the corners to rounded, the loading structure 20 can easily enter and exit the dissolving tank 311.
[0096] In some embodiments, the grid 213 includes a plurality of first rods 2131 and a plurality of second rods 2132, the first rods 2131 and the second rods 2132 being cross-connected, the first rods 2131 connecting to two first side plates 214, and the second rods 2132 connecting to two second side plates 215. This arrangement helps to ensure the strength of the grid 213 while facilitating the flow of liquid.
[0097] In some embodiments, a corresponding second rod 2132 of the two-layer grid 213 is located directly below the slot 2153, and the stop member 220 forms a slot 221. When the stop member 220 is detachably inserted into the slot 2153, the corresponding second rod 2132 of the two-layer grid 213 enters the slot 221, preventing the stop member 220 from shaking and falling off. Through the cooperation between the slot 221 and the second rod 2132, the stop member 220 can enter or leave the slot 2153 more smoothly, and each second rod 2132 can be connected to the second side plate 215, ensuring the mechanical strength of the grid 213.
[0098] See Figure 10 , Figure 10 This is an exploded schematic diagram of the insertion portion of the first rod 2131 and the second rod 2132 according to an embodiment of this application. In some embodiments, the first rod 2131 forms a plurality of insertion portions 21311, and the second rod 2132 forms a plurality of insertion mating portions 21321. The connection between the first rod 2131 and the second rod 2132 is realized through the insertion and mating of the insertion portions 21311 and the insertion mating portions 21321.
[0099] The insertion portion 21311 can be, for example, a first slot formed above the first rod 2131, and the insertion mating portion 21321 can be a second slot formed below the second rod 2132. The first rod 2131 is inserted into the second rod 2132 below it. In some embodiments, the length of the first rod 2131 is smaller than the length of the second rod 2132. Placing the first rod 2131 below the second rod 2132 helps to improve the overall strength of the lattice structure 213 and makes it less prone to breakage.
[0100] In some embodiments, both the first side plate 214 and the second side plate 215 (i.e., the second side plate 215 without side openings 2151) away from the stop member 220 are provided with two sets of side through holes 216, each set of side through holes 216 including a plurality of side through holes 2161 distributed along the height direction. Providing side through holes 2161 helps to reduce the overall weight of the loading structure 20.
[0101] In some embodiments, the number of side through holes 2161 in each side through hole group 216 is the same as the number of radioactive plate samples, and each side through hole 2161 is located between two layers of radioactive plate samples.
[0102] In order to ensure sufficient exchange of liquid between the inside and outside of the loading structure 20, the loading structure 20 can be moved up and down in the dissolution tank. By positioning each side through hole 2161 between two layers of radioactive plate-shaped samples, the exchange efficiency of liquid between the inside and outside of the loading structure 20 can be improved, thereby allowing the radioactive plate-shaped samples to be dissolved more fully.
[0103] In some embodiments, multiple side through holes 2161 can be directly machined on the side plate. Compared with a side plate with through holes formed by splicing multiple plates, a side plate with directly machined side through holes has higher mechanical strength.
[0104] In some embodiments, the width of the side through holes 2161 can be greater than the spacing between the side through holes 2161. This arrangement can reduce the overall weight of the loading structure 20 without significantly affecting the mechanical strength of the side plate; it can also further improve the exchange efficiency of liquid between the inside and outside of the loading structure 20.
[0105] In some embodiments, the hoisting assembly 217 is disposed above the two-layer grid 213.
[0106] In some embodiments, the lifting mating part 217 may include a lifting channel 2171, wherein the lifting channel 2171 includes a first guide hole section 21711, a second guide hole section 21712 and a third guide hole section 21713 in sequence along its extension direction. The inner wall of the second guide hole section 21712 is parallel to the extension direction of the lifting channel 2171, and the aperture size at the second guide hole section 21712 is the smallest. The first guide hole section 21711 extends obliquely toward the second guide hole section 21712, and the third guide hole section 21713 extends obliquely toward the second guide hole section 21712. The third guide hole section 21713 forms two recesses to accommodate the lifting part 120.
[0107] Specifically, the inner wall of the second guide hole section 21712 can be four right trapezoids that are connected sequentially along the circumference and arranged symmetrically in adjacent pairs, and the inner wall of the third guide hole section 21713 can be four triangles that are connected sequentially along the circumference and arranged symmetrically in adjacent pairs. With this arrangement, a recess extending toward the first guide hole section 21711 can be formed between the two opposite right triangles of the third guide hole section 21713.
[0108] The lifting part 120 can have a non-circular structure, such as an elliptical shape. The lifting part 120 can enter the lifting channel 2171 from top to bottom, and then rotate the lifting part 120 so that both ends of the lifting part 120 are engaged with the two recesses to achieve stable lifting. The inclined arrangement of the second guide hole section 21712 and the third guide hole section 21713 is beneficial to guiding the lifting part 120 in and out of the lifting channel 2171.
[0109] See still Figure 11 and Figure 12In some embodiments, the lifting mating part 217 may further include multiple connecting plates 2172, respectively used to connect the plate forming the lifting channel 2171 to the first side plate 214 and the second side plate 215. Specifically, the lifting mating part 217 may include four connecting plates 2172, respectively used to connect two first side plates 214 and two second side plates 215. Specifically, one connecting plate 2172 may be connected to the slot mating member 2152. The upper surface of the lifting mating part 217 may be flush with the upper end surfaces of the first side plate 214 and the second side plate 215.
[0110] In some embodiments, the radioactive material dissolution system further includes a feeding device (not shown) configured to add a liquid for dissolving radioactive materials into the dissolution tank 311 of the dissolution device 30. The liquid may be hydrofluoric acid, etc.
[0111] In some embodiments, the feeding device includes a feed pipe through which the liquid enters the dissolving tank 311.
[0112] In some embodiments, the radioactive material dissolution system further includes a dissolution degree determining device configured to determine the degree of dissolution of the radioactive material within the dissolution device 30.
[0113] See Figure 13 In some embodiments, the dissolution degree determination device includes a measuring line 701 and a radioactivity measuring component 40. The measuring line 701 is used to receive the dissolving liquid from the dissolving device 30; the radioactivity measuring component 40 is used to measure the radioactivity of the dissolving liquid in the measuring line 701. The determination device provided by the embodiments of this application can determine the dissolution degree of a radioactive material by measuring the radioactivity of the dissolving liquid.
[0114] The measuring line 701 can be in fluid communication with the dissolving device 30.
[0115] See Figures 14 to 16 In some embodiments, the radioactivity measurement assembly 40 includes a radioactivity measuring element 410 and a shielding housing. The radioactivity measuring element 410 is used to measure radioactivity; the shielding housing encloses the measuring conduit 701 and the radioactivity measuring element 410, so that the radioactivity measuring element 410 can only measure the radioactivity of the measuring conduit 701. The shielding housing can shield against external radioactivity influences, making the radioactivity measured by the radioactivity measuring element 410 more accurate.
[0116] In some embodiments, the radioactivity measurement assembly further includes a first heat insulation element 441, which is fitted onto the measurement conduit 701 to prevent heat from being transferred from the measurement conduit 701 to the shielding housing.
[0117] The inventors of this application discovered that the temperature of the solution inside the measuring pipe 701 is high, and heat is transferred through the measuring pipe 701 to the shielding shell, and then through the shielding shell to the radioactivity measuring element 410, which affects the measurement results of the radioactivity measuring element 410. The embodiments of this application, by providing a first heat insulation element 441, can reduce the transfer of heat from the measuring pipe 701 to the shielding shell, thereby making the measurement results of the radioactivity measuring element 410 more accurate.
[0118] See Figure 16 In some embodiments, a through groove 440 is provided on the side of the first heat insulation member 441 facing the radioactivity measuring member 410. The radioactivity measuring assembly 40 further includes: a second heat insulation member, which is filled in the through groove 440 and between the first heat insulation member 441 and the radioactivity measuring member 410, wherein the gamma-ray absorption rate of the second heat insulation member is less than the gamma-ray absorption rate of the first heat insulation member 441.
[0119] The inventors of this application discovered that while the first heat insulation element 441 can reduce the influence of temperature on the measurement, it also blocks gamma rays in the measuring pipeline 701, affecting the measurement results. Based on this, the inventors of this application provided a through-groove 440 in the first heat insulation element and filled the through-groove 440 with a second heat insulation element that has a lower gamma ray absorption rate. Thus, by providing the through-groove 440 on the side of the first heat insulation element 441 facing the radioactive measuring element 410, and with the first and second heat insulation elements working together for insulation, a good insulation effect can be achieved without significantly affecting the gamma ray absorption rate, thereby improving the measurement accuracy.
[0120] In some embodiments, the first heat insulation element can be made of polytetrafluoroethylene, which can provide heat insulation while also facilitating the fixing of the shielding shell and the measuring pipeline 701.
[0121] In some embodiments, the second thermal insulation element may be a silica aerogel insulation felt. The measuring pipeline 701 is a stainless steel pipeline, and the shielding housing is installed on the measuring pipeline 701.
[0122] See Figures 14 to 16 In some embodiments, the shielding housing includes a plurality of shielding elements connected together by fasteners 433.
[0123] Specifically, the shielding housing may include a first shielding member 431 and a second shielding member 432 disposed opposite to each other.
[0124] The first shield 431 has a first through hole for the passage of the wire 411 of the radiometric measuring element 410.
[0125] The first shielding member 431 may include two opposing first side plates 4312, a second side plate 4314 connecting the two first side plates 4312, a base plate 4313 connecting the two first side plates 4312 and the second side plate 4314, and a cover plate for the two first side plates 4312 and the second side plate 4314. The cover plate has through holes for the cables of the radioactivity measuring device 410 to pass through.
[0126] The first shielding member 431 may include a body and a groove formed on the body, and the first heat insulation member 441 is disposed in the groove. The first heat insulation member 441 has a through hole for accommodating the measuring pipeline 701.
[0127] The cover plate includes a first plate 4311 and a second plate 434. The first plate 4311 is connected to two first side plates 4312 and a second side plate 4314, and the second plate 434 is connected to the two first side plates 4312 by fasteners. The first plate 4311 has a half-hole 43111, and the second plate 434 has a half-hole 4341, which together form a through hole in the cover plate. The second plate 434 also forms a groove 4342, and the bottom plate 4313 forms a groove 43131 to mate with a groove on the body of the second shielding member 432, so as to facilitate the installation of the first heat insulation member 441.
[0128] The first heat insulation component 441 consists of two halves. One half is connected to the body of the second shielding component 432 via fasteners; the other half has a through groove 440, which is connected to the second plate 434 and the base plate 4313 via fasteners. The body of the second shielding component 432 is also connected to the second plate 434 and the base plate 4313 via fasteners 433. This arrangement facilitates both the installation of the first heat insulation component 441 to the shielding housing and the filling of the second heat insulation component inside the shielding housing.
[0129] In some embodiments, see Figure 17 The determining device also includes a measuring auxiliary component 50, which includes an auxiliary container 51 and a liquid level measuring component 55.
[0130] The auxiliary container 51 is in fluid communication with the measuring line 701 and is used to receive the solution in the measuring line 701. The measuring auxiliary component 50 may include a solution inlet pipe 54, which is in fluid communication with the measuring line 701.
[0131] The liquid level measuring device is used to measure the liquid level in the auxiliary container 51. The radioactivity measuring component 40 measures the radioactivity of the solution in the measuring pipeline 701 after the liquid level in the auxiliary container 51 reaches a preset value. The auxiliary container 51 helps determine when the radioactivity measuring component 40 should perform its measurement. When the liquid level measuring device detects that the liquid level in the auxiliary container 51 has reached the preset value, it indicates that the measuring pipeline 701 is full of solution, and the radioactivity measuring component 40 can then be used to measure it, thus preventing inaccurate measurement results if the measuring pipeline 701 is not yet full.
[0132] In some embodiments, the auxiliary container 51 is further provided with an air outlet for connection to a vacuum pump to create a negative pressure in the auxiliary container 51, so that the solution in the dissolving device 30 enters the auxiliary container through the measuring pipe 701 under the action of the negative pressure.
[0133] In some embodiments, the auxiliary container 51 is provided with an air inlet for supplying gas into the auxiliary container 51 to change the auxiliary container 51 from a negative pressure environment to a normal pressure environment, so that when the dissolution tank 311 of the dissolution device 30 forms a negative pressure, the dissolving liquid in the auxiliary container 51 returns to the dissolution device 30 via the measuring pipeline 701 under the action of the pressure difference.
[0134] In some embodiments, the determining device may further include a return line 702, which is in fluid communication with the outlet pipe 53 of the auxiliary container 51 and the dissolving device 30. Valves are provided on the return line 702 and the measuring line 701 respectively. When it is necessary to return the dissolving liquid to the dissolving device 30, the dissolving liquid can be returned to the dissolving device 30 through the return line 702.
[0135] In some embodiments, the auxiliary container 51 is configured to form an annular receiving cavity 511, which helps to avoid criticality problems.
[0136] See Figure 18 and Figure 19 In some embodiments, the measuring aid 50 may also include a liquid outlet pipe 53, which is in fluid communication with the return pipe 702 and is used to allow the liquid in the receiving cavity 511 to leave the receiving cavity 511 and return to the dissolving device 30. The liquid inlet 531 of the liquid outlet pipe 53 is located at the bottom of the annular receiving cavity 511.
[0137] In some embodiments, the dissolving device 30 is connected to an external negative pressure supply device, and the liquid in the receiving cavity 511 is drawn into the return pipe 702 through the liquid outlet pipe 53 by negative pressure suction.
[0138] See Figure 18In some embodiments, the outlet pipe 53 abuts against the bottom wall 5111 of the annular receiving cavity 511, and the inlet 531 is formed by a groove formed by the recess on the end face of the outlet pipe 53. In such embodiments, it is beneficial for the liquid in the receiving cavity 511 to be extracted as completely as possible.
[0139] In some embodiments, the end face of the outlet pipe 53 can be formed with multiple grooves, that is, multiple inlets 531 can be formed, so that the liquid in the receiving cavity 511 is extracted from the receiving cavity 511 as much as possible.
[0140] In some embodiments, the bottom wall 5111 of the annular cavity 511 is an inclined surface extending downward from the radially outer side to the radially inner side, so that the remaining small amount of liquid in the cavity 511 flows along the inclined surface to converge at a lower position. In some embodiments, the outlet pipe 53 is disposed adjacent to the radially inner wall of the annular cavity 511 to facilitate the entry of liquid into the outlet pipe 53.
[0141] In some embodiments, the slope may further form a recess 51111, the bottom surface of which is flat and connects to the radially inner edge of the bottom wall 5111. In such an embodiment, a small amount of liquid remaining in the receiving cavity 511 can flow along the slope to the lowest point and then enter the recess 51111. The outlet pipe 53 abuts against the bottom surface to facilitate the removal of liquid entering the recess 51111 by the outlet pipe 53.
[0142] In some embodiments, the auxiliary container 51 may include an annular outer shell 512, an annular inner shell 513, a bottom plate 515, and a top plate 514. The annular inner shell 513 is disposed radially inside the annular outer shell 512, and both ends of the annular inner shell 513 and both ends of the annular outer shell 512 are fixedly connected to the bottom plate 515 and the top plate 514, respectively; the annular outer shell 512, the annular inner shell 513, the bottom plate 515, and the top plate 514 together form an annular receiving cavity 511.
[0143] In some embodiments, the liquid outlet pipe 53, the gas outlet pipe, the gas inlet pipe, the dissolving liquid inlet pipe 54, and the liquid level measuring element 55 are all provided on the top plate 514.
[0144] In some embodiments, a portion of the liquid in the dissolution tank 311 may enter the auxiliary container 51. When the liquid in the auxiliary container 51 reaches a preset level, the supply of liquid to the auxiliary container 51 is stopped. Then, the liquid that entered the auxiliary container 51 is returned to the dissolution tank 311, thereby stirring the liquid in the dissolution tank 311 and accelerating the dissolution of radioactive materials.
[0145] In some embodiments, the level measuring element of the determining device can be a level probe, and the determining device can have two level probes at different heights. The low level probe is used to indicate when the radioactivity measuring component 40 starts measuring when the radioactivity of the solution in the measuring line 701 is measured; the high level probe is used to indicate when the liquid in the dissolving tank 311 stops entering the auxiliary container 51 when the liquid in the dissolving tank 311 is stirred.
[0146] In some embodiments, the radioactive material dissolution system may be located inside a glove box.
[0147] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.
