[0026] Exemplary embodiments of the present application will be described below in conjunction with the accompanying drawings. For the sake of clarity and conciseness, not all features of the actual implementation are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the process of developing any such actual implementation in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and these constraints may vary from implementation to implementation. In addition, it should be understood that although the development work may be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the content of this application.

[0027] It is also necessary to explain here that, in order to avoid obscuring the present application due to unnecessary details, only the device structure and / or processing steps closely related to the scheme according to the present application are shown in the accompanying drawings, while other details that are not very relevant to the present application are omitted.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in this application should have the common meanings understood by persons with ordinary skills in the field to which this application belongs.

[0029] In the description of the embodiments of the present application, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] like Figure 1 As shown, the radioactive material dissolution system of the embodiment of the present application may include: a plurality of dissolution devices 100 , a heating assembly 150 and a separation device 400 .

[0031] In some embodiments, each of the plurality of dissolving devices 100 can be used to dissolve the radioactive powder material with the feed liquid to obtain a solution containing the radioactive material. The heating component 150 can be used to provide heated fluid to heat the feed liquids in the plurality of dissolving devices 100 with the fluid. The separation device 400 can be used to separate the radioactive powder material that is not completely dissolved from the solution in the dissolving device 100.

[0032] The embodiments of the present application can utilize fluid to heat the liquid containing radioactive powdered material in multiple dissolving devices 100, which is beneficial to reduce the temperature variation amplitude in the dissolving device 100, ensure that the temperature of each dissolving device 100 is basically the same, and increase the dissolution rate of the radioactive powdered material; utilize the separation device 400 to separate the radioactive powdered material dissolved in the dissolving device 100 from the dissolving liquid to realize the transfer of the radioactive material.

[0033] In some embodiments, the heating component 150 can use a constant temperature circulating bath to control the heating temperature. For example, the heating component 150 can be implemented by a constant temperature circulating machine. The temperature of the main container 120 when the heating component 150 heats the main container 120 can be in the range of 20-125°C.

[0034] In some embodiments, see Figures 2 to 4 The dissolving device 100 may include a dissolving container 110, a main container 120, an ultrasonic generator 130, and a heating chamber 151. The dissolving container 110 may be used to contain radioactive powdered material and liquid. The main container 120 may be used to place the dissolving container 110. The main container 120 contains liquid. The ultrasonic generator 130 may be used to provide ultrasound and transmit the ultrasound to the dissolving container 110 through the liquid in the main container 120, so as to accelerate the dissolution of the radioactive powdered material by the liquid in the dissolving container 110 by using ultrasound. The heating chamber 151 may be provided in the main container 120. The heating chamber 151 may be used to receive the fluid provided by the heating component 150, so as to heat the main container 120.

[0035] In the related art, the volume of the dissolution container is usually large, for example, several tens of liters. For such a dissolution container, in order to improve the dissolution efficiency of the material for the radioactive material, a mechanical stirring method is usually used to stir the radioactive powder material and the material in the dissolution container. In some cases, the radioactive powder material that needs to be dissolved is small. At this time, if a large amount of material is used to dissolve the radioactive powder material, the concentration of the radioactive material in the dissolving solution will be greatly reduced, and subsequent treatment will also produce a large amount of radioactive waste liquid; if a small amount of material is used to dissolve the radioactive powder material, this process is usually carried out in a relatively small space. The mechanical stirring method is easy to cause operational inconvenience when applied to a relatively small space due to its relatively complex structural parts and limited installation position. Therefore, it is inconvenient to set a mechanical stirring structure on a smaller dissolution container.

[0036] The embodiment of the present application uses a dissolving container 110, a main container 120, an ultrasonic generator 130 and a heating chamber 151 in coordination, and can use a small dissolving container 110 (for example, a volume of 100-200 ml and an inner diameter of 40-60 mm) to dissolve a small amount of radioactive powdered material, thereby avoiding the generation of excessive and unnecessary radioactive waste liquid; at the same time, it can also accelerate the dissolution of the radioactive powdered material by the dissolving liquid in the dissolving container 110, so as to further improve the dissolution degree of the radioactive powdered material, thereby achieving a better dissolution effect.

[0037] Radioactive powdered material can achieve a better dissolution effect when the temperature is within a preset temperature range. In the related art, an electric heater is usually used to directly heat the dissolution device 100. However, for the smaller dissolution container 110 in the present application, the heating method of the electric heater will cause the temperature of the dissolution container 110 to vary greatly, affecting the dissolution effect. The present application uses the heating method of transferring heat to the dissolution container 110 through the liquid in the main container 120, which is more conducive to reducing the temperature variation of the dissolution container 110.

[0038] In some embodiments, the dissolving container 110 may include a container cover 111 and a container body 112. The container body 112 may be a container made of glass. The container cover 111 may be a plug cover to achieve sealing of the container body 112.

[0039] A plurality of openings 113 and an inlet and outlet 114 may be formed on the container cover 111. The plurality of openings 113 may include an auxiliary gas inlet and a gas outlet. The auxiliary gas inlet may be used to add auxiliary gas to the dissolution container 110 to improve the dissolution effect. The gas outlet may be used to discharge excess gas from the dissolution container 110. The auxiliary gas inlet and the gas outlet may be provided with a one-way valve and a filter to prevent liquid backflow. The inlet and outlet 114 may be used to sample the dissolved liquid in the dissolution container 110 or to add liquid to the dissolution container 110. The liquid may be an acid solution capable of dissolving radioactive substances.

[0040] In some embodiments, the inlet and outlet 114 can be configured as a funnel-shaped opening, and the inlet and outlet 114 can be provided with a sealing plug that is easily removable, so as to facilitate the user to take samples or add liquid to the dissolution container 110. A dropper can be used to take samples from the inlet and outlet 114, and the inlet and outlet 114 can be plugged with a sealing plug after the sampling is completed.

[0041] In some embodiments, the volume of the dissolving container 110 can be 100-200 ml, and the inner diameter is 40-60 mm. When the inner diameter of the dissolving container 110 is 40-60 mm, the effective diameter of the container cover 111 for arranging the opening 113 and the inlet and outlet 114 is also only 40-60 mm. In this case, the container cover 111 does not have enough space to set the mechanical stirring structure, so it is difficult to accelerate the dissolution of the radioactive material by stirring the material and the radioactive powder material in the dissolving container 110. The embodiment of the present application accelerates the efficiency of the material in the dissolving container 110 dissolving the radioactive powder material by setting the main container 120 and the ultrasonic generator 130.

[0042] In some embodiments, the frequency of the ultrasound provided by the ultrasound generator 130 may be 40 kHz, 100 kHz, or 200 kHz to accelerate the dissolution of the radioactive powder material by the dissolving liquid in the dissolution container 110 .

[0043] In some embodiments, the dissolution system may further include a controller that can be used to control the frequency of ultrasound emitted by the ultrasound generator 130 .

[0044] In some embodiments, see Figure 2 , the heating assembly 150 may include a fluid loading member 152, a heating member 1502 and a temperature measuring member 153. The fluid loading member 152 may be used to load a fluid. The fluid loading member 152 may be in fluid communication with the heating chamber 151. The heating member may be used to heat the fluid in the fluid loading member 152. The temperature measuring member 153 may be used to measure the temperature of the fluid, so as to adjust the heating power of the heating member according to the temperature measured by the temperature measuring member 153.

[0045] The embodiment of the present application heats the fluid loaded in the fluid loading member 152 and delivers the heated fluid to the heating chamber 151 to heat the main container 120. In this way, the temperature of the main container 120 can be kept stable within a preset temperature range to ensure that the radioactive powder material can be dissolved well.

[0046] In some embodiments, reference Figures 2 to 4 The heating assembly 150 may include a heating jacket 1501. The heating jacket 1501 forms a heating chamber 151. The heating jacket 1501 may be disposed around the outer wall of the main body container 120 to heat the main body container 120 after the heated fluid loaded in the fluid loading member 152 enters the heating chamber 151.

[0047] In some embodiments, the fluid carrier 152 may be a shell. A heating interface may be provided on the fluid carrier 152 for connecting the heater 1502. The fluid carrier 152 may be provided with a liquid inlet and a liquid return port. The fluid carrier 152 may be in fluid communication with the heating chamber 151 through the liquid inlet and the liquid return port on the side wall.

[0048] In some embodiments, the controller may also receive the temperature measured by the temperature measuring element 153 and adjust the heating power of the heating element 1502 according to the received temperature.

[0049] In some embodiments, the heating assembly 150 may further include a liquid inlet manifold 154, a liquid inlet manifold 155, a plurality of liquid inlet branch pipes 156, a plurality of liquid return branch pipes 157, a liquid return manifold 158, and a liquid return manifold 159. The liquid inlet manifold 154 may be in fluid communication with the fluid carrier 152. The liquid inlet manifold 155 may be used to be in fluid communication with the liquid inlet manifold 154. Each of the plurality of liquid inlet branch pipes 156 may be used to connect the liquid inlet manifold 155 with a heating chamber 151 to introduce fluid into the heating chamber 151. Each of the plurality of liquid return branch pipes 157 may be used to be in fluid communication with a heating chamber 151 to allow the fluid in the heating chamber 151 to enter the liquid return branch pipe 157. The liquid return manifold 158 may be used to be in fluid communication with the plurality of liquid return branch pipes 157. The liquid return main pipe 159 can be used to connect the liquid return multi-way piece 158 and the fluid carrying part 152, so that the fluid entering the liquid return multi-way piece 158 returns to the fluid carrying part 152. The temperature measuring part 153 can be arranged on the liquid return multi-way piece 158.

[0050] The embodiments of the present application are based on the liquid inlet main pipe 154, the liquid inlet multi-way piece 155, the multiple liquid inlet branch pipes 156, the multiple liquid return branch pipes 157, the liquid return multi-way piece 158 and the liquid return main pipe 159 included in the heating component 150, which can respectively supply the heated fluid to the multiple heating chambers 151 to heat the multiple main containers 120 simultaneously.

[0051] When a fluid carrier 152 supplies fluid to multiple heating chambers 151, in order to simultaneously control the temperature of multiple heating chambers 151, a temperature measuring element 153 is usually disposed in the fluid carrier 152. The inventor of the present application has found that when the fluid flows in the heating chamber 151 and the fluid flows in the pipeline, due to heat dissipation, the temperature in the heating chamber 151 and the temperature measured by the temperature measuring element 153 will have a significant difference. In addition, the embodiment of the present application is further provided with an ultrasonic generator 130. When ultrasound is used to accelerate the dissolution of the radioactive powder substance by the dissolving liquid in the dissolving container 110, ultrasound will also heat the main container 120 and the dissolving container 110. When the temperature of the liquid in the main container 120 and the dissolving container 110 increases, the heating element 1502 needs to reduce the power.

[0052] The embodiment of the present application sets the temperature measuring component 153 on the liquid return multi-channel component 158, which can simultaneously regulate the temperature of multiple heating chambers 151, and can reflect that ultrasound also heats the main container 120 and the dissolution container 110, and the heat dissipation when the fluid flows in the heating chamber 151 and the fluid flows in the pipeline. The measurement results are more beneficial for temperature regulation.

[0053] In some embodiments, see Figure 2The liquid inlet multi-channel member 155 may include a plurality of liquid inlet interfaces 1551, a liquid inlet body 1552 and a liquid inlet main interface. A first valve 1553 may be provided on each liquid inlet interface 1551. The fluid in the fluid carrier 152 may flow to the liquid inlet main pipe 154. The fluid in the liquid inlet main pipe 154 may enter the liquid inlet body 1552 via the liquid inlet main interface. The plurality of liquid inlet interfaces 1551 may be used to divert the fluid in the liquid inlet body 1552, so as to send the fluid to the liquid inlet branch pipe 156 corresponding to the first valve 1553 being in the open state, and finally to the corresponding heating chamber 151.

[0054] The plurality of liquid inlet interfaces 1551 are symmetrically arranged on opposite sides of the liquid inlet body 1552 , and the main liquid inlet interface is arranged at the symmetrical center of the liquid inlet body 1552 , so that the fluid entering the liquid inlet body 1552 can be more evenly distributed to the liquid inlet interfaces 1551 .

[0055] See also Figure 3 The heating chamber 151 may be formed with a heating liquid inlet interface 1511. The heating liquid inlet interface 1511 is used to allow the fluid in the corresponding liquid inlet branch pipe 156 to enter the heating chamber 151. Similar to the liquid inlet multi-channel member 155, see Figure 5 The liquid return multi-way piece 158 may include a plurality of liquid return interfaces 1581, a liquid return body 1582 and a liquid return main interface. A second valve 1583 may be provided on each liquid return interface 1581. The heating chamber 151 may be formed with a heating liquid return interface 1512. The fluid in the heating chamber 151 may flow to the corresponding liquid return branch pipe 157 via the heating liquid return interface 1512. The fluid in the liquid return branch pipe 157 with the second valve 1583 in the open state may enter the liquid return body 1582.

[0056] The fluid in the liquid return body 1582 can flow to the liquid return main pipe 159 through the liquid return main interface and return to the fluid carrier 152. The plurality of liquid return interfaces 1581 are symmetrically arranged on opposite sides of the liquid return body 1582, and the liquid return main interface is arranged at the symmetrical center of the liquid return body 1582, so that the fluid entering the liquid return body 1582 through each liquid inlet interface 1551 can be more evenly distributed to the liquid return main interface.

[0057] The heating liquid inlet interface 1511 and the heating liquid return interface 1512 formed on each heating chamber 151 may be formed on opposite sides of the heating chamber 151. The temperature measuring element 153 may be disposed on the liquid return body 1582. Specifically, the temperature measuring element 153 may be disposed opposite to the liquid return main interface, so as to measure the temperature of the fluid near the liquid return main interface, so that the temperature measured by the temperature measuring element 153 is more accurate, so that the controller can more accurately adjust the heating power of the heating element 1502.

[0058] In some embodiments, reference Figure 4The ultrasonic generator 130 may be provided with a connector 131. The main body container 120 may be provided with a connecting fitting 121. Through the cooperation of the connector 131 and the connecting fitting 121, a detachable connection between the ultrasonic generator 130 and the main body container 120 may be achieved.

[0059] The embodiment of the present application can facilitate the user to disassemble or replace the ultrasonic generator 130 or the main container 120 through the cooperation between the connecting piece 131 and the connecting fitting 121.

[0060] In some embodiments, the connection between the connecting member 131 and the connecting fitting 121 may be threaded.

[0061] In some embodiments, the radioactive material dissolution system may further include a magnetic stirring assembly 160. The magnetic stirring assembly 160 may be used to magnetically stir the dissolution container 110. In the embodiment of the present application, based on the use of ultrasound to accelerate the dissolution of the radioactive powder material by the dissolving liquid in the dissolution container 110, the magnetic stirring assembly 160 may also be used to magnetically stir the dissolution container 110 to further accelerate the dissolution efficiency of the radioactive powder material by the dissolving liquid in the dissolution container 110.

[0062] As mentioned above, the dissolving container 110 of the embodiment of the present application is not convenient for setting a mechanical stirring structure, and therefore, ultrasonic vibration and magnetic stirring are used to achieve a better dissolving effect.

[0063] In some embodiments, the bottom wall of the dissolution container 110 and the main container 120 may be spaced 4-5 mm apart so that the magnetic stirring assembly 160 can achieve a better vibration effect, thereby improving the stirring efficiency.

[0064] In some embodiments, the magnetic stirring assembly 160 may include a magnetic stirring member 161, a rotating member 162, and a magnetic stirring driving member 163. The magnetic stirring member 161 may be disposed in the dissolution container 110. The rotating member 162 may be disposed on the outside of the main container 120. The magnetic stirring driving member 163 may be disposed on the rotating member 162, and is used for the rotating member 162 to drive the magnetic stirring driving member 163 to rotate, thereby driving the magnetic stirring member 161 to rotate.

[0065] In order to ensure the stirring effect of the magnetic stirring member 161, the magnetic stirring driving member 163 is usually arranged at the center of the bottom of the main body container 120. In the embodiment of the present application, since the ultrasonic generator 130 is arranged at the center of the bottom of the main body container 120, there is not enough space to arrange the magnetic stirring driving member 163. Therefore, in the embodiment of the present application, the magnetic stirring driving member 163 is arranged radially outside the main body container 120 to achieve the driving of the magnetic stirring member 161.

[0066] The embodiment of the present application utilizes the magnetic stirring member 161 and the rotating member 162, and can drive the magnetic stirring member 161 to rotate when the rotating member 162 drives the magnetic stirring driving member 163 to rotate. In this way, not only can the dissolved liquid in the dissolution container 110 be fully stirred, but also there is no need to install an additional stirring member on the body of the dissolution container 110, so as to facilitate the replacement of the dissolution container 110.

[0067] In some embodiments, the surface of the magnetic stirring member 161 may be coated with an acid-resistant material, such as polytetrafluoroethylene. Figure 4 The rotating member 162 can be configured as a cylinder. A recessed portion can be formed on the upper portion of the cylinder for arranging the magnetic stirring driving member 163.

[0068] The bottom of the main container 120 is located in the cylinder, and the ultrasonic generator 130 can be disposed inside the cylinder.

[0069] In some embodiments, the rotating member 162 may be disposed below the heating chamber 151 .

[0070] In some embodiments, the magnetic stirring drive 163 may be a magnet or a coil.

[0071] In some embodiments, the magnetic stirring driving member 163 may include two magnets arranged opposite to each other. The magnets may be arranged on the rotating member 162. Since the material in the dissolving container 110 is a strong acid and may volatilize, the magnet is used as the magnetic stirring driving member 163, which is better suitable for acidic environments than the coil.

[0072] In some embodiments, the dissolving device 100 may further include a protective shell 170 disposed outside the rotating member 162 .

[0073] In some embodiments, the main body container 120 includes a main body cover 122 and a main container body 123. The container body 112 is installed on the main body cover 122 and passes through the main body cover 122 into the main container body 123.

[0074] In some embodiments, the dissolving container 110 further includes a clamping member 115, which is disposed on the container body 112 and is used to cooperate with the main body cover 122. The container body 112 is clamped to the main body cover 122 through the clamping member 115. This arrangement not only realizes the connection between the dissolving container 110 and the main body container 120, but also facilitates the ultrasonic penetration of the container body 112 to vibrate the dissolved liquid.

[0075] In some embodiments, the magnetic stirring assembly 160 may further include a motor 164. The motor 164 may be used to drive the rotating member 162 to rotate. The motor 164 may be disposed below the rotating member 162.

[0076] In some embodiments, the dissolving device 100 may further include a lifting member 140. The lifting member 140 may be used to drive the main body container 120 and the ultrasonic generator 130 to move out of or into the rotating member 162, so as to facilitate the user to replace the main body container 120 and / or the ultrasonic generator 130.

[0077] In some embodiments, reference Figures 2 to 4 , the lifting member 140 may include a support rod 141, a clamping member 142 and a movable connecting rod 143. The clamping member 142 is used to clamp the heating jacket 1501. The movable connecting rod 143 is used to connect the clamping member 142 to the support rod 141. The movable connecting rod 143 can also drive the clamping member 142 to move relative to the support rod 141 to move the main body container 120 and the ultrasonic generator 130 out of the rotating member 162 or allow the main body container 120 and the ultrasonic generator 130 to enter the rotating member 162.

[0078] In some embodiments, reference Figures 6 to 9 , the separation device 400 may include a first separation container 410, a second separation container 420, a filter 430 and a connecting assembly 440. The first separation container 410 may be used to receive dissolved radioactive powder material and dissolving liquid. The first separation container 410 may have a first opening 411. The second separation container 420 may have a second opening 421. The second opening 421 and the first opening 411 of the first separation container 410 may be arranged opposite to each other. The first separation container 410 is inverted so that its first opening 411 is arranged downward.

[0079] The filter 430 may be disposed between the first opening 411 and the second opening 421 to allow the solution in the first separation container 410 to enter the second separation container 420 through the filter 430. The connecting assembly 440 may be used to connect the filter 430 between the first opening 411 and the second opening 421.

[0080] Generally speaking, the volume of the dissolved liquid in the dissolving container 110 does not exceed 60% of the volume of the dissolving container 110. For example, for a dissolving container 110 with a volume of 100 milliliters, the volume of the dissolved liquid does not exceed 60 milliliters. At present, existing separation devices are designed for more dissolved liquids. For a small amount of dissolved liquid, there is no suitable device for separation. The embodiments of the present application can filter the radioactive powder material remaining in the dissolved liquid of the dissolving container 110 through the coordinated use between the first separation container 410, the second separation container 420, the filter element 430 and the connecting assembly 440, thereby realizing solid-liquid separation.

[0081] The inventor of the present application has found that due to the small amount of dissolved liquid, the gravity that can be provided is small, and the resistance of the liquid when flowing through the filter element 430 is large, resulting in low separation efficiency. In some embodiments, the dissolution system may include a vacuum pump. The vacuum pump can be used to evacuate the second separation container 420 to accelerate the flow of the liquid to the second separation container 420 via the filter element 430, thereby accelerating the separation efficiency.

[0082] In some embodiments, the volume of the first separation container 410 may be 100 mL. The first separation container 410 may be a glass container.

[0083] In some embodiments, the filter element 430 may include a skeleton and a filter membrane detachably disposed on the skeleton. A plurality of filter holes may be formed on the filter membrane, and the pore size of the filter holes is smaller than the size of the radioactive powder material, so that when the dissolved liquid flows through the filter holes of the filter membrane, the liquid is allowed to flow through the filter holes, while the solid powder in the dissolved liquid is retained by the filter membrane. After the filtration is completed, the filter membrane can be directly removed from the skeleton, so as to facilitate subsequent treatment of the solid powder. In some embodiments, the filter membrane may be a polytetrafluoroethylene filter membrane.

[0084] In some embodiments, the diameter of the filter 430 may be 25 mm.

[0085] In some embodiments, the first separation container 410 and the second separation container 420 may be containers made of glass materials, respectively. The first separation container 410 may also include a first body, and the diameter of the first opening 411 may be smaller than the diameter of the first body of the first separation container 410. The first separation container 410 may also include a first transition section, and the first body and the first opening 411 are connected by the first transition section. The first transition section and the first opening 411 form a funnel shape to facilitate the dissolving liquid in the first body to enter the first opening 411.

[0086] The second separation container 420 may be a glass test tube or a polyethylene test tube, so that the second separation container 420 can have better applicability.

[0087] In some embodiments, the connection assembly 440 may include a first connection member 441, a second connection member 442, and a third connection member 443. The first connection member 441 may be used to connect to the first opening portion 411 of the first separation container 410. The second connection member 442 may be used to connect to the second opening portion 421 of the second separation container 420. The third connection member 443 may be used to connect to the first connection member 441 and the second connection member 442, respectively. The filter 430 may be disposed between the third connection member 443 and the first opening portion 411 of the first separation container 410. By configuring the connection assembly 440 to include the first connection member 441, the second connection member 442, and the third connection member 443, a sealed connection between the first separation container 410 and the second separation container 420 can be achieved.

[0088] In some embodiments, the first connecting member 441 and the first opening 411, the second connecting member 442 and the third connecting member 443, and the second connecting member 442 and the second opening 421 can be threadedly connected. This arrangement is conducive to sealing the first separation container 410 and the second separation container 420 while facilitating assembly and disassembly.

[0089] In some embodiments, the first connector 441 may include a first connector body 4411 and a first matching portion 4412 connected to the first connector body 4411. The second connector 442 may include a second connector body 4421, a first matching portion 4422 and a second matching portion 4423. The first matching portion 4422 and the second matching portion 4423 are connected to both axial ends of the second connector body 4421, respectively.

[0090] In some embodiments, the third connecting member 443 may include a third connecting body 4431, a first matching portion 4432, a second matching portion 4433, and a drainage portion 4434. The first matching portion 4432 and the second matching portion 4433 are respectively connected to the axial ends of the third connecting body 4431, and the second matching portion 4433 is connected to the drainage portion 4434. The third connecting body 4431, the first matching portion 4432, the second matching portion 4433, and the drainage portion 4434 jointly form a third channel 4430, and the dissolved liquid filtered by the filter element 430 enters the third channel 4430 and enters the second opening 421.

[0091] In some embodiments, the first connecting body 4411 is used to be threadedly connected to the first opening 411 of the first separation container 410; the first connecting body 4411 and the first matching part 4412 form a first channel 4410. The second matching part 4423 is used to be threadedly connected to the second opening 421 of the second separation container 420; the first matching part 4422 is used to be threadedly connected to the second matching part 4433. The second connecting body 4421, the first matching part 4422, and the second matching part 4423 form a second channel 4420. The first matching part 4432 enters the first channel 4410, and the first matching part 4432 and the first connecting body 4411 can rotate relative to each other, so as to facilitate the disassembly and assembly of the first connecting member 441, the second connecting member 442, and the third connecting member 443 with the first separation container 410 and the second separation container 420. The inner diameter of the first matching part 4412 is smaller than the outer diameter of the second matching part 4423, and is equal to the outer diameter of the third connecting body 4431. The outer diameter of the third connecting body 4431 is larger than the inner diameter of the second matching portion 4433, and the inner diameter of the second matching portion 4433 is larger than the inner diameter of the drainage portion 4434. The drainage portion 4434 can enter the second opening 421 through the second channel 4420 to ensure that the filtered solution enters the second separation container 420 completely.

[0092] In some embodiments, the third connecting body 4431, the second matching portion 4433, and the drainage portion 4434 are located outside the first channel 4410, and the second matching portion 4433 and the drainage portion 4434 are located inside the second channel 4420. This connection method is convenient for disassembling the first separation container 410 and the second separation container 420, and also has good sealing performance to prevent the radioactive dissolved solution from flowing out.

[0093] In some embodiments, the first mating portion 4432 forms a filter groove 44320 , and the filter groove 44320 is in fluid communication with the third channel 4430 .

[0094] The filter element 430 is disposed above the filter tank 44320 so that the filter holes of the filter element 430 are in fluid communication with the filter tank 44320 , thereby facilitating the liquid to flow through the filter holes and enter the filter tank 44320 .

[0095] In some embodiments, see Fig. 9 The second connecting member 442 is provided with a vacuum port 44210, which is used to communicate with a vacuum pump through a vacuum pipeline, so as to evacuate the second separation container 420 through the vacuum port 44210. The vacuum port 44210 can be provided on the second connecting body 4421, and is in fluid communication with the second channel 4420. Since the drainage portion 4434 passes through the second channel 4420 and enters the second opening portion 421, the second channel 4420 can avoid sucking the filtered solution into the vacuum pipeline.

[0096] In some embodiments, the separation device 400 may further include a mounting frame 450. The mounting frame 450 may be used to mount the second separation container 420.

[0097] In some embodiments, the mounting frame 450 may include a second support member 451 extending in the vertical direction, a fixed connection member 452 extending in the horizontal direction, and a plurality of clamping members 453. The second support member 451 may be used to support the fixed connection member 452, and a plurality of mounting grooves may be formed on the fixed connection member 452. The shape of the mounting groove matches the second connection member 442. The clamping member 453 may be installed on the second connection member 442 on the mounting groove of the fixed connection member 452, thereby fixing the second separation container 420, the connection assembly, and the first separation container 410 as a whole to the mounting frame 450.

[0098] In the embodiment of the present application, since the vacuum port 44210 is arranged on the second connecting member 442, and the clamping member 453 installs the second connecting member 442 on the installation groove of the fixed connecting member 452, this arrangement is conducive to ensuring the stability of each separation container and the connecting component during vacuuming.

[0099] In some embodiments, the radioactive material dissolution system may further include an auxiliary gas provider 500 and a gas exhaust pipeline 600. The auxiliary gas provider 500 may be used to provide gas that is conducive to promoting the dissolution reaction to the dissolution container 110, so as to further improve the dissolution efficiency of the radioactive powder material. The gas exhaust pipeline 600 may be used to discharge the gas formed after the reaction and the unreacted auxiliary gas out of the dissolution container 110, so as to prevent the gas formed after the reaction from affecting the dissolution effect of the radioactive powder material or the unreacted auxiliary gas from flowing into the air.

[0100] In some embodiments, reference Figure 2, the auxiliary gas providing part 500 may include multiple flow meters 510, multiple gas branch pipes 520, a gas multi-pass part 530, a gas main pipe and a gas carrying part. The flow meter can be used to adjust the flow rate of the auxiliary gas. In an embodiment of the present application, the maximum flow rate of the auxiliary gas can be in the range of 40-60 ml / min. The gas multi-pass part 530 may include multiple gas flow outlets 531, a multi-pass part body 532, a total gas inlet and a valve 533 corresponding to each gas flow outlet. The gas carrying part can be used to load auxiliary gas. The gas carrying part can be connected to the multi-pass part body 532 through the gas main pipe and the total gas inlet on the gas multi-pass part 530 to transport auxiliary gas to the multi-pass part body 532. The multi-pass part body 532 can transport auxiliary gas to the dissolution container 110 through multiple gas flow outlets 531, multiple gas branch pipes 520 and the flow meter 510 thereon. A regulating valve can also be provided on the flow meter 510 to control the gas flow rate in the corresponding gas flow outlet. Exemplarily, the regulating valve may be a stainless steel needle valve.

[0101] In some embodiments, the radioactive material dissolution system may include a concentration measuring device 200. The concentration measuring device 200 may be configured to measure the concentration of the radioactive material in the dissolution device 100. The embodiment of the present application can accurately determine the degree of dissolution of the radioactive material in the dissolution device when the radioactive material is dissolved by using the concentration measuring device 200. Specifically, a dropper may be used to take a sample from the inlet and outlet 114, the sample taken out may be placed in the concentration measuring device 200 for measurement, and the inlet and outlet 114 may be plugged with a sealing plug after the sampling is completed.

[0102] In some embodiments, the radioactive material dissolution system may further include a preheating device 700 and a solution pump. The preheating device 700 may be used to preheat a dissolving solution containing a radioactive powder material. The solution pump may be used to pump the preheated dissolving solution to a corresponding dissolving container 110. When the preheating device 700 heats the dissolving solution to a temperature close to a preset temperature, the solution pump may pump the dissolving solution to a corresponding dissolving container 110. The embodiments of the present application may preheat the dissolving solution to avoid the situation where the dissolving solution containing the radioactive powder material is heated slowly by directly using a heating component; the heating efficiency of the dissolving solution may be improved, thereby improving the dissolution efficiency of the radioactive material. Specifically, the preheating device 700 includes a preheating container and a heating element for preheating the preheating container.

[0103] In some embodiments, the radioactive material dissolution system may further include a plurality of first liquid inlet pipelines, a plurality of second liquid inlet pipelines, a first liquid inlet main pipe, and a second liquid inlet main pipe. One end of each first liquid inlet pipeline extends into the interior of the preheating container, and the other end is connected to the solution pump through the first liquid inlet main pipe. One end of each second liquid inlet pipeline extends into the inlet and outlet port 114 of the dissolution container 110, and the other end is connected to the solution pump through the second liquid inlet main pipe. The preheated liquid in each preheating container is transported to the dissolution container 110 through the solution pump.

[0104] The preheating container can be a beaker or a glass test tube.

[0105] In some embodiments, when using the radioactive material dissolution system of the embodiment of the present application to dissolve radioactive powder materials, the heating component 150 and the preheating device 700 can be turned on first to heat the main container 120 and the preheating container respectively. After the temperature reaches the set value and maintains equilibrium, the radioactive powder sample to be dissolved is weighed and placed in the dissolution container 110, and then the liquid pump is turned on to inject the preheated liquid in the preheating container into the dissolution container 110. The amount of injection is determined according to the experimental requirements, but the liquid level should not exceed 2 / 3 of the total height of the dissolution container 110. Introduce carrier gas, and after the temperature is balanced, turn on the power of the ultrasonic generator and the power of the magnetic stirring component 160 to start dissolution.

[0106] During the dissolution process, a small amount of dissolved liquid can be taken out through the inlet and outlet 114 using a dropper for measurement to determine the degree of dissolution.

[0107] After dissolution, the dissolved liquid in the dissolution container 110 is transferred to the first separation container 410. After the second separation container 420, the filter element 430 and the connecting assembly are assembled with the first separation container 410, the first separation container 410 is inverted, and the second connecting element 442 is installed on the mounting groove of the fixed connecting element 452. After that, the vacuum pump is turned on, and the liquid in the first separation container 410 is filtered and enters the second separation container 420 by negative pressure filtration, and the remaining powder in the solution is filtered onto the filter element 430 for subsequent analysis.

[0108] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.
