[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Combine the following Figures 1 to 9 The radioactive waste conditioning line and conditioning method of the present invention are described.

[0046] As attached Figure 1 and attached Figure 2 As shown, the radioactive waste preparation line includes a preparation line shielding box chamber 1, a transfer vehicle passage 19 is arranged in the middle of the lower part of the preparation line shielding box chamber 1, a preparation room 11 is arranged in the upper part of the preparation line shielding box chamber 1, and a plurality of solid waste rooms 12 are arranged on both sides of the transfer vehicle passage 19, and the solid waste room 12 is located below the preparation room 11.

[0047] Specifically, a plurality of manipulators 13 are arranged on the preparation room 11. The preparation room inner covers 14 equal in number to the solid waste rooms 12 are arranged at the bottom of the preparation room 11, and feeding ports 15 are arranged below the preparation room inner covers 14, and the feeding ports 15 correspond to the solid waste rooms 12 one by one.

[0048] A seal 16 is provided at the top of the solid waste chamber 12, and a centering clamping drive component 17 is provided at the bottom of the solid waste chamber 12. A solid waste bucket 18 is installed on the centering clamping drive component 17. The centering clamping drive component 17 is used to drive the solid waste bucket 18 to move vertically up and down. The feed port of the solid waste bucket 18 is located directly below the feeding port 15.

[0049] When in use, place the radioactive waste on the transfer barrel on the transfer cart, then move the transfer cart to the transfer cart channel 19 by external force, and then lift the transfer barrel by the lifting mechanism of the transfer cart, so that the transfer barrel is connected to the preparation room 11, and the preparation room 11 is now isolated from the outside world. Then place the solid waste barrel 18 on the centering clamping drive component 17, and the centering clamping drive component 17 drives the solid waste barrel 18 to move vertically upward, so that the feed port of the solid waste barrel 18 is aligned with the feeding port 15, and the solid waste barrel 18 is in contact with the sealing member 16, thereby isolating the preparation room 11 from the solid waste room 12, and then open the preparation room inner cover 14, so that the preparation room 11 and the solid waste barrel 18 are connected. Then, the radioactive waste in the transfer barrel is separated into solid and liquid by the manipulator 13, and the manipulator 13 extracts the liquid radioactive waste barrel into the storage container. Then the manipulator 13 grabs the solid radioactive waste from the transfer barrel and puts it into the solid waste barrel 18 through the feeding port 15, thereby realizing the safe transfer of radioactive waste, avoiding the pollution of the environment in the solid waste room 12 when the preparation room 11 operates radioactive materials, and further avoiding the pollution of the operating environment of personnel when the contaminated solid waste barrel 18 is transferred out of the solid waste room 12, thereby ensuring the safety of the environment and personnel.

[0050] When the solid waste barrel 18 in one of the solid waste chambers 12 is full of radioactive waste, the preparation chamber inner cover 14 is closed to isolate the preparation chamber 11 from the solid waste barrel 18, and the manipulator 13 transfers the new radioactive waste to the solid waste barrel 18 in another solid waste chamber 12, and so on, until the radioactive waste in the solid waste barrel 18 in the first solid waste chamber 12 decays to the non-radioactive standard, the solid waste barrel 18 is taken out and replaced in the empty solid waste barrel 18, and then the manipulator 13 can transfer the radioactive waste to the solid waste barrel 18 in the first solid waste chamber 12 again. When the solid waste barrel 18 in the first solid waste chamber 12 is full, the radioactive waste in the solid waste barrel 18 of the second solid waste chamber 12 decays to the non-radioactive standard, and so on, so that multiple solid waste chambers 12 are recycled.

[0051] In an optional embodiment of the present invention, the sealing member 16 is, for example, a sealing pad, but it should be understood that any other suitable structure with a sealing function can be used as the sealing member 16 .

[0052] In an optional embodiment of the present invention, the wire preparation shielding box 1 is composed of a shielding wall. However, it should be understood that the wire preparation shielding box 1 can also be composed of any other suitable structure with a shielding function.

[0053] Among them, in an optional embodiment of the present invention, the transfer bucket of the transfer vehicle uses the double-cover sealing and locking mechanism in the patent application number CN201811099206.9, and the transfer bucket and the preparation room are sealed and connected by using the double-cover sealing and locking structure. However, it should be understood that the transfer bucket can also have any other suitable sealing and locking structure.

[0054] Further, as attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, the centering clamping drive component 17 includes a centering clamping base 171, a plurality of centering clamping blocks 172, a plurality of driving members 173 and a centering column 174 fixedly installed at the center of the centering clamping base 171. The centering clamping base 171 is fixedly installed at the bottom of the solid waste chamber 12, the centering clamping blocks 172 are installed on the centering clamping base 171, the driving member 173 is fixedly installed at the bottom of the centering clamping base 171, and a groove matching the centering column is provided at the bottom of the solid waste barrel 18. When in use, the solid waste barrel 18 is installed on the centering clamping base 171, so that the centering column 174 is inserted into the groove of the solid waste barrel 18, and the centering clamping block 172 fixes the solid waste barrel 18, so that the feeding port of the solid waste barrel 18 is always located directly below the feeding port 15, and then the driving member 173 drives the centering clamping base 171 to move upward, and the solid waste barrel 18 moves upward until the feeding port of the solid waste barrel 18 is aligned with the feeding port 15, and the solid waste barrel 18 abuts against the sealing member 16, thereby realizing the stable upward movement of the solid waste barrel 18, ensuring that the solid waste barrel 18 is tightly connected to the feeding port 15, isolating the preparation room 11 and the solid waste chamber 12, avoiding the pollution of the environment in the solid waste chamber 12 when the preparation room 11 operates radioactive materials, and thus avoiding the pollution of the operating environment of the personnel when the contaminated solid waste barrel 18 is transferred out of the solid waste chamber 12, thereby ensuring the safety of the environment and the staff.

[0055] The centering clamping block 172 is slidably connected to the centering clamping base 171. When in use, the staff can adjust the position of the centering clamping block 172 according to the size of the solid waste bucket 18 actually used, so that the centering clamping block 172 can just clamp and fix the solid waste bucket 18, thereby improving the practicality of the transfer box room.

[0056] Among them, as attached Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, in an optional embodiment of the present invention, there are, for example, four centering clamping blocks 172 , and the four centering clamping blocks 172 are installed on the centering clamping base 171 at equal intervals.

[0057] Further, as attached Figure 1 and attached Figure 2As shown, the solid waste bucket 18 is horizontally mounted on the centering clamping drive component 17, and the upper end surface of the solid waste bucket 18 is parallel to the seal 16. When in use, the centering clamping drive component 17 drives the solid waste bucket 18 to move vertically upward, and the upper end surface of the solid waste bucket 18 always remains parallel to the seal 16, so that the solid waste bucket 18 can just dock with the feeding port 15, and the upper end surface of the solid waste bucket 18 abuts against the seal 16, so that the feeding port 15 is only connected to the solid waste bucket 18, isolating the feeding port 15 from the solid waste chamber 12, avoiding the pollution of the environment in the solid waste chamber 12 when the preparation room 11 operates radioactive materials, and further avoiding the pollution of the operating environment of personnel when the contaminated solid waste bucket 18 is transferred out of the solid waste chamber 12, thereby ensuring the safety of the environment and staff.

[0058] Further, as attached Figure 6 As shown, the upper wall surface of the solid waste chamber 12 protrudes downward with a hollow cylinder 121 that matches the feeding port of the solid waste barrel 18. One end of the hollow cylinder 121 is sealed and connected to the feeding port 15, and the sealing member 16 is installed on the inner wall surface of the hollow cylinder 121. When in use, the centering clamping driving component 17 drives the solid waste barrel 18 to move upward, so that the upper end of the solid waste barrel 18 is embedded in the hollow cylinder 121, and the feeding port of the solid waste barrel 18 is docked with the feeding port 15. The sealing member 16 is located between the solid waste barrel 18 and the hollow cylinder 121 at this time, so that the hollow cylinder 121 is isolated from the solid waste chamber 12, and then the preparation room 11 is isolated from the solid waste chamber 12, so as to avoid the pollution of the environment in the solid waste chamber 12 when the preparation room 11 operates radioactive materials, and then avoid the pollution of the operating environment of personnel when the contaminated solid waste barrel 18 is transferred out of the solid waste chamber 12, thereby ensuring the safety of the environment and the staff.

[0059] Further, as attached Figure 1 and attached Figure 2 As shown, a shielding door 122 is provided on the inner wall surface of the solid waste chamber 12, and a sealing strip is provided on the shielding door 122. When in use, by opening the shielding door 122, the solid waste barrel 18 can be conveniently put in and out of the solid waste chamber 12. When the solid waste barrel 18 is placed in the solid waste chamber 12 to transport radioactive waste, the shielding door 122 is closed to prevent the leakage of radioactive substances. The sealing strip can further ensure that the solid waste chamber 12 is isolated from the outside world, ensuring that the radioactive substances in the solid waste chamber 12 will not leak out and pollute the environment. When the decay of the radioactive waste in the solid waste barrel 18 in the solid waste chamber 12 reaches the standard of the dose rate that can be operated by personnel, the shielding door 122 is opened, and then the solid waste barrel 18 is transferred to a designated location for placement.

[0060] Further, as attached Figure 7As shown, the radioactive waste preparation line also includes a liquid waste temporary storage component 2 and a liquid waste storage tank 3. The liquid waste temporary storage component 2 is located on one side of the preparation line shielding box chamber 1, and the liquid waste temporary storage component 2 is connected to the liquid waste storage tank 3. When in use, the radioactive waste is transferred to the preparation room 11 for solid-liquid separation, and the manipulator 13 sucks the liquid waste into the liquid waste temporary storage component 2. When the liquid waste temporary storage component 2 is full of liquid waste, the liquid waste is discharged from the liquid waste temporary storage component 2 to the liquid waste storage tank 3, avoiding the problems of more residual liquid waste in the pipeline and inconvenience in sampling liquid waste caused by directly transferring liquid waste to the liquid waste storage tank 3.

[0061] The liquid waste temporary storage component 2 includes a plurality of liquid buffer tanks. When in use, the liquid waste is first extracted into the liquid buffer tank. When the liquid buffer tank is filled with liquid waste, the liquid waste is discharged from the liquid buffer tank into the liquid waste storage tank 3. In order to avoid frequent replacement of storage tanks, the general liquid waste storage tank 3 is relatively large in size and is mostly buried underground. By setting up the liquid buffer tank, it is convenient for the staff to conduct random inspections of the liquid waste and effectively avoid excessive liquid waste residues in the pipeline.

[0062] Further, as attached Figure 8 As shown, an upper automatic switch assembly 151 and a lower automatic switch assembly 152 are provided in the feeding port 15 , the lower automatic switch assembly 152 is located below the upper automatic switch assembly 151 , and a transfer chamber is provided between the upper automatic switch assembly 151 and the lower automatic switch assembly 152 . During use, when the manipulator 13 starts to transfer the radioactive waste into the solid waste barrel 18 through the feeding port 15, the manipulator 13 clamps the radioactive waste from the transfer barrel and moves it to the feeding port 15, and then allows the radioactive waste to fall into the feeding port 15, and then the upper automatic switch component 151 is opened, and the lower automatic switch component 152 is closed, and the radioactive waste falls into the transfer chamber, and then the upper automatic switch component 151 is closed, the lower automatic switch component 152 is opened, and the radioactive waste falls into the solid waste barrel 18, and then the lower automatic switch component 152 is closed, thereby realizing the transfer of reflective waste and further isolating the preparation room 11 and the solid waste chamber 12, avoiding the pollution of the environment in the solid waste chamber 12 when the preparation room 11 operates radioactive materials, and further avoiding the pollution of the personnel operating environment when the contaminated solid waste barrel 18 is transferred out of the solid waste chamber 12, thereby ensuring the safety of the environment and staff.

[0063] Among them, as attached Figure 8As shown, both the upper automatic switch assembly 151 and the lower automatic switch assembly 152 include a detection element 153 and an electric valve 154, and the detection element 153 is located above the electric valve 154. When in use, when the detection element 153 detects that an object has passed, the detection element 153 sends a corresponding signal to the electric valve 154, and the electric valve 154 opens, thereby realizing the automatic opening and closing of the upper switch assembly and the lower switch assembly, thereby improving the automation of radioactive waste transfer.

[0064] In an optional embodiment of the present invention, the detection element 153 is, for example, an infrared sensor, but it should be understood that any other suitable element with a detection function can be used as the detection element 153 .

[0065] On the other hand, if the Fig. 9 As shown, the present invention also provides a method for preparing radioactive waste, comprising:

[0066] 401. Transfer the radioactive waste to the preparation room in a sealed manner;

[0067] 402. Move the solid waste barrel into the solid waste chamber, lift the solid waste barrel so that the feeding port of the solid waste barrel is sealed and connected with the feeding port of the preparation chamber, and then open the inner cover of the preparation chamber. At this time, the solid waste barrel is connected with the preparation chamber, and the preparation chamber is isolated from the solid waste chamber;

[0068] 403. Classify and prepare radioactive waste, transfer solid radioactive waste into solid waste barrels, and transfer liquid radioactive waste into liquid buffer tanks;

[0069] 404. Close the inner cover of the preparation room to isolate the preparation room from the solid waste barrel, and place the solid waste barrel in isolation in the solid waste room for decay.

[0070] When in use, the method of sealing and transferring radioactive waste into the preparation room specifically refers to the content in the invention patent with patent number CN201811099169.1, and no further description is given here. When the radioactive waste is transferred to the preparation room, the preparation room is isolated from the transfer vehicle channel to prevent leakage of radioactive materials. The radioactive waste is then transferred to the solid waste barrel through the feeding port. When the solid waste barrel is full, it is necessary to close the inner cover of the preparation room first, and then move the solid waste barrel down, thereby ensuring that the preparation room and the solid waste room are always isolated from each other, avoiding pollution of the environment in the solid waste room when the preparation room operates radioactive materials, and thus avoiding pollution of the operating environment of personnel when the contaminated solid waste barrel is transferred out of the solid waste room, thereby ensuring the safety of the environment and staff.

[0071] Furthermore, the steps of transferring the solid radioactive waste into the solid waste barrel specifically include:

[0072] 501. Transfer the solid radioactive waste to the solid waste barrel in the first solid waste room. When the solid waste barrel in the first solid waste room is full of radioactive waste, transfer the solid radioactive waste to the solid waste barrel in the second solid waste room, and so on;

[0073] 502. When the radioactive waste in the solid waste barrel in the first solid waste room decays to a dose rate standard that can be operated by personnel, the solid waste barrel filled with radioactive waste is transferred out of the first solid waste room, a new solid waste barrel is transferred into the first solid waste room, and then the radioactive waste is transferred again into the solid waste barrel in the first solid waste room;

[0074] 503. When the solid waste barrel in the first solid waste room is filled with radioactive waste again, the radioactive waste in the solid waste barrel in the second solid waste room decays to the dose rate standard that can be operated by personnel. The solid waste barrel in the second solid waste room is replaced with a new solid waste barrel, and then the radioactive waste is transferred to the second solid waste room, and so on, forming a recycling between two or more solid waste rooms.

[0075] When in use, the number of solid waste barrels required can be calculated based on the amount of solid radioactive waste generated by the production line, the half-life of the radioactive waste and the capacity of the solid waste barrel. In actual applications, the number of solid waste barrels can be adjusted according to actual conditions to achieve the recycling of multiple solid waste barrels. Similarly, the required number of liquid buffer tanks can also be calculated to achieve the recycling of liquid buffer tanks. Each solid waste barrel is placed separately in a solid waste room, which effectively avoids the impact between solid waste barrels and ensures that when the decay time of the radioactive waste is reached, the radioactive waste in the solid waste barrel can reach the dose rate standard that can be operated by personnel, thereby achieving the safe transfer of radioactive waste, preventing leakage of radioactive materials, avoiding cross-contamination between different environments, and ensuring the safety of staff.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
