[0082] In some embodiments, the sampling system 30 includes a sampling buffer container 31 and a sampling container 32. Fig.13 and Fig.14 As shown, Fig.13 A schematic diagram showing the structure of a sampling system 30 according to an embodiment of the present application is shown. Fig.14 Show Fig.13 The enlarged view of the B area in the middle. The sampling buffer container 31 is in fluid communication with the dissolution system 20; a switch valve 33 is provided between the sampling buffer container 31 and the dissolution system 20, and the switch valve 33 can control whether the fluid between the sampling buffer container 31 and the dissolution system 20 is in fluid communication or not; the sampling container 32 is in fluid communication with the sampling buffer container 31. In this embodiment, by providing the sampling buffer container 31, the high-pressure solution flowing out of the closed and high-pressure dissolution system 20 is first flowed into the sampling buffer container 31 for temporary storage, so as to prevent the solution from directly entering the sampling container 32.

[0083] In some embodiments, the sampling buffer container 31 and the dissolution system 20 are arranged so that the liquid level of the sampling buffer container 31 is higher than the liquid level of the dissolution system 20, so that after the sampling is completed, the dissolved liquid in the sampling buffer container 31 can automatically flow back to the dissolution system 20 under the action of gravity, thereby avoiding the dissolved liquid remaining in the sampling buffer container 31 and affecting the next sampling result.

[0084] In some embodiments, the sampling buffer container 31 is provided with a sampling liquid inlet 311 and a sampling liquid outlet 312 at its bottom. The sampling liquid outlet 312 is in fluid communication with the sampling container 32, so that the liquid in the sampling buffer container 31 flows into the sampling container 32; the sampling liquid inlet 311 is in fluid communication with the dissolution system 20, and the liquid from the dissolution system 20 flows into the sampling buffer container 31 from the sampling liquid inlet 311. The sampling liquid inlet 311 is arranged so that its flow direction is perpendicular to the flow direction of the liquid, such as Fig.14 As shown, the pressure and flow rate of the liquid are reduced to prevent the liquid from impacting the top of the container after entering the sampling buffer container 31.

[0085] The sampling buffer container 31 is formed with a cavity, and a cylindrical boss 316 is provided at the bottom of the cavity. Fig.14 As shown, the sampling liquid inlet 311 is arranged on the side wall of the cylindrical boss 316, and a plurality of sampling liquid inlets 311 can be arranged along the circumferential direction of the cylindrical boss 316 to divert the liquid when entering the sampling buffer container 31, so as to further reduce the pressure and flow rate of the liquid.

[0086] In some embodiments, the sampling buffer container 31 is also provided with a liquid level detection component 313, and the liquid level detection component 313 is arranged above the sampling liquid inlet 311. A baffle is arranged above the sampling liquid inlet 311 to protect the liquid level detection component 313 and prevent the splashing of high-pressure liquid from causing accidental touching of the liquid level detection component 313, thereby causing detection errors.

[0087] The liquid level detection member 313 is configured to control the volume of liquid flowing into the container by sensing the liquid level height in the sampling buffer container 31. For example, the liquid level detection member 313 may be a liquid level conductivity switch. A portion of the liquid level detection member 313 is disposed inside the cavity of the sampling buffer container 31, and another portion is disposed outside the cavity. The liquid level height in the sampling buffer container 31 is sensed by the portion disposed inside the cavity. When the liquid rises to a predetermined liquid level, the opening and closing state of the portion disposed outside the cavity is changed, so that liquid no longer flows into the sampling buffer container 31.

[0088] like Fig.13 As shown, in some embodiments, a needle 314 is connected to the lower end of the sampling buffer container 31, and the needle 314 can pierce the end of the sampling container 32 during sampling, so that the sampling liquid does not contact the outside world during the sampling process, thereby achieving closed sampling and ensuring the accuracy of the test results.

[0089] The needle 314 may be configured to be connected to the sampling liquid outflow port 312 of the sampling buffer container 31 , so that the liquid in the sampling buffer container 31 can directly flow into the sampling container 32 through the sampling liquid outflow port 312 via the needle 314 .

[0090] In some embodiments, the sampling system 30 further includes a pressure detection member 34, which is configured to be connected to the sampling buffer container 31 and configured to detect the pressure in the sampling buffer container 31 to ensure that the pressure in the sampling buffer container 31 meets the requirements. The pressure detection range of the pressure detection member 34 is -0.1MPa to 0.15MPa.

[0091] In some embodiments, the sampling buffer container 31 is also provided with a negative pressure interface 315, which draws negative pressure into the sampling buffer container 31 so that after the sampling is completed, the needle 314, the sampling liquid outlet 312 and the residual liquid in the pipeline can be returned to the sampling buffer container 31, thereby avoiding interference with the next sampling.

[0092] Specifically, after sampling is completed, the interior of the sampling buffer container 31 is pumped to a slightly negative pressure state through the negative pressure interface 315, and the valve controlling the connection between the sampling liquid outflow port 312 and the sampling container 32 is quickly opened and then closed, so that under the action of air pressure, the needle 314, the sampling liquid outflow port 312 and the liquid remaining in the pipeline are returned to the sampling buffer container 31.

[0093] In some embodiments, the sampling buffer container 31 is further provided with a vent 317, through which the pressure inside the sampling buffer container 31 is released, so that the inside is in a normal pressure state. After the high-pressure liquid in the dissolution system 20 flows into the sampling buffer container 31, the pressure inside the sampling buffer container 31 is released by the vent 317, so that the liquid flowing into the sampling container 32 is in a normal pressure state.

[0095] Specifically, the buffer 51 is evacuated by a vacuum pump so that the gas in the dissolution system 20 is introduced into the buffer 51 from the fluid inlet 5121 under the action of negative pressure, thereby providing negative pressure to the dissolution system 20 .

[0096] The vacuum pump is configured to extract the gas in the buffer 51 at a predetermined speed to provide a stable negative pressure to the dissolution system 20. For example, the extraction speed of the vacuum pump can be set to 20 m / s. 3 / h.

[0133] The stirring tube 8132 extends to the bottom of the seasoning container 81, so that the stirring gas passes through the liquid layer from the bottom of the seasoning container 81 to the top in the form of bubbles, thereby fully mixing the solution inside the seasoning container 81.

[0134] like Fig.21 As shown, the external structure 812 is also provided with an air suction port 814 and a liquid inlet 815, which are arranged outside the external structure 812 and communicated with the inside of the external structure 812.

[0138] like Fig.23 As shown, Fig.23 The schematic diagram of the assembly of the adsorption column 82 and the manual three-way valve 83 of the ion adsorption system 80 of one embodiment of the present application is shown. In some embodiments, the adsorption column 82 includes at least two adsorption columns 82, at least two adsorption columns 82 are arranged in parallel, and at least two adsorption columns 82 are connected to the fluid of the seasoning container 81 at one end.

[0139] like Fig.23 As shown, in some embodiments, the ion adsorption system 80 may further include a manual three-way valve 83, which is disposed between one end of at least two adsorption columns 82 and the seasoning container 81, so that one of the two adsorption columns 82 is fluidically connected to the seasoning container 81, and the other of the two adsorption columns 82 is not fluidically connected to the seasoning container 81.

[0142] The specific process of using the radioactive powder dissolving device with automatic material pouring and dispensing in the present application is further described below with specific examples.

[0143] The transfer gripper 121 of the transfer component 12 of the material dispensing and dispensing system 10 grabs the container containing the radioactive powder sample from the outside, and carries the container to move along the moving channel 12211 of the transfer platform component 122. When the container moves to the vicinity of the temporary storage area 12212, the pushing members 1223 on both sides of the temporary storage area 12212 push the container into the temporary storage area 12212, and the suction cup 12221 of the opening member 1222 sucks the cover of the container, and the lifting part 12222 drives the suction cup 12221 and the cover of the container sucked by it to rise, so as to open the cover of the container. The transfer gripper 121 continues to grab the container containing the radioactive powder sample after the lid is opened, moves along the moving channel 12211 of the transfer platform assembly 122 to the pouring assembly 13, places the container on the receiving piece 131, and controls the receiving piece 131 to flip 180° through the flipping piece 132, so that the powder sample in the container is poured out. At this time, the vibrator 1311 is turned on to vibrate the container, and the poured powder sample flows along the pipeline 133 to the temporary storage silo 134 for temporary storage. The radioactive powder sample in the temporary storage bin 134 is introduced through the introduction port 1142 of the supporting member 114 of the quantitative feeding assembly 11, and falls into the groove 1111 along the conical channel 1143. The fixed plate 115 is driven to move by the linear driving unit 113, which drives the quantitative feeding member 111 to move along a straight line, so that the powder sample can fall into a plurality of grooves 1111 of different quantities. The quantitative feeding member 111 is then rotated by the rotating driving unit 112, so that the powder sample in one of the grooves 1111 is thrown onto the weighing member 116. The powder sample falls into the receiving portion 1162 from the receiving port 11612 of the weighing piece 116, and the weighing sensor 1164 weighs the powder sample in the receiving portion 1162. After the weighing is completed, the rotating portion 1163 is driven to rotate and drive the receiving portion 1162 to rotate 180°. The powder sample in the receiving portion 1162 falls along the conical structure 11613 under the action of gravity, and after flowing out from the opening 11614, it is added to the receiving piece 23 of the dissolution system 20.

[0144] The feeding system 40 is used to add the feed liquid for dissolving the radioactive powder sample into the cavity 221 of the dissolution system 20, and the cover 21 of the dissolution system 20 is rotated, so that the multiple hooks 2111 of the rotating quick-release structure 211 clamp the multiple protrusions 2221 of the matching structure 222, and the multiple hooks 2111 are matched with the multiple protrusions 2221 in a one-to-one correspondence, and the multiple protrusions 2221 provide a tightening force to the multiple hooks 2111, thereby forming a pre-tightening force on the C-type sealing member provided between the cover 21 and the body 22 to seal the dissolution system 20. The radioactive powder sample is dissolved in the feed liquid to obtain a dissolving liquid. During the dissolution process, the stirring member 24 is used for stirring, and the heating jacket is used to heat the feed liquid.

[0145] During the dissolution process, the dissolving liquid in the dissolution system 20 is taken out by the sampling system 30 to detect the dissolution of the powder sample. When sampling, the switch valve 33 of the sampling system 30 is opened to allow the dissolving liquid in the dissolution system 20 to flow into the cavity of the sampling buffer container 31 from the sampling liquid inlet 311 of the sampling buffer container 31, and the pressure inside the sampling buffer container 31 is released through the piercing hole 317. Then, the needle 314 connected to the lower end of the sampling buffer container 31 is used to pierce the end of the sampling container 32, and the dissolving liquid in the cavity of the sampling buffer container 31 flows directly into the sampling container 32 from the sampling liquid outlet 312 through the needle 314, thereby completing the sampling. After the sampling is completed, the interior of the sampling buffer container 31 is pumped to a slightly negative pressure state through the negative pressure interface 315, and the valve controlling the communication between the sampling liquid outlet 312 and the sampling container 32 is quickly opened and closed, so that the needle 314, the sampling liquid outlet 312 and the residual liquid inside the pipeline are returned to the sampling buffer container 31.

[0146] When the sampling result reaches the predetermined requirement, the solution generated by the dissolution system 20 is input to the filtration system 70, and the undissolved residue in the solution is removed by the filtration system 70. After that, the filtered solution is input to the external structure 812 of the seasoning container 81 of the ion adsorption system 80, and the solution for adjusting the acidity and valence of the solution is added to the seasoning container 81 through the feeding system 40, and the bubbling stirring structure 813 is used to stir in the external structure 812, so that the solution and the solution are fully mixed, and the acidity and valence of the solution are adjusted, and then the solution is extracted by the extraction structure 816 and transported to the adsorption column 82, and the adsorption column 82 is used to adsorb impurities on the solution to remove impurities in the solution.

[0147] The tail gas generated by the dissolution system 20 is transported to the tail gas treatment system 60 for treatment. The tail gas enters the gas guide 619 from the gas inlet 613 of the condensation treatment part 61. Cooling water flows into the first cavity 6101 from the cooling water inlet 611 to condense the gas in the gas guide 619. The condensed liquid and the uncondensed gas enter the second cavity 6102. The condensed liquid is sucked away from the liquid extraction port 615 through the liquid extraction part 6103, and the uncondensed gas flows out from the gas outlet 614 to the liquid absorption part 62. After the uncondensed gas enters the first cavity 6201 of the liquid absorption part 62 from the gas inlet 621, it flows into the second cavity 6202 through the hole 6261 and the gas guide line 627 to react with the treatment liquid. The tail gas not absorbed by the treatment liquid flows out from the gas outlet 622, thereby completing the tail gas treatment.

[0148] 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.
