[0033] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0034] refer to Figure 1 The UO2 powder transfer device provided in the embodiments of the present application includes a suction unit 1, a receiving unit 2, and a docking mechanism 3. Through the cooperation between the suction unit 1, the receiving unit 2, and the docking mechanism 3, the UO2 powder is transferred into a 200L material barrel. This mechanical method replaces manual operation, reducing the risk of radioactive powder damage to on-site personnel.

[0035] The suction unit 1 includes a first operating glove box 16, a suction assembly, and a vacuum conveyor 111. The first operating glove box 16 is a negative pressure glove box that can accommodate a material transport container. The suction end of the suction assembly is located within the first operating glove box 16 and is used to suck UO2 powder from the material transport container under the action of the vacuum conveyor 111. The suction assembly and the first operating glove box 16 are sealed together, ensuring that the suction process is carried out in a negative pressure sealed environment.

[0036] The receiving unit 2 includes a second operating glove box 21, in which a receiving bucket 23 can be placed. The second operating glove box 21 is a negative pressure glove box. In this way, the receiving bucket 23 is ensured to be in a negative pressure sealed environment when receiving UO2 powder.

[0037] The docking mechanism 3 includes a docking tube 31, one end of which extends into the second operating glove box 21 and is sealed therewith. The docking tube 31 is also sealed with both the vacuum conveyor 111 and the material receiving bucket 23. The vacuum conveyor 111 and the suction assembly are sealed together via a conveying conduit. Under the action of the vacuum conveyor 111, the UO2 powder flows through the suction assembly, the conveying conduit, and the docking tube 31 before being delivered to the material receiving bucket 23. This ensures a sealed conveying process.

[0038] The UO2 powder transfer device provided in the embodiment of the present application includes a material suction unit 1, a material receiving unit 2, and a docking mechanism 3. The sealed connections between the various components of the material suction unit 1, the material receiving unit 2, and the docking mechanism 3 ensure a sealed system for the entire UO2 powder transfer process, including suction, conveying, and unloading. This reduces the amount of UO2 powder spillage and minimizes the risk of damage to personnel on site.

[0039] The first operating glove box 16 and the second operating glove box 21 are both sealed and can provide a negative pressure environment, further reducing the amount of UO2 powder overflowing.

[0040] In some embodiments, the material transport container includes a first material transport barrel 12, and the first operating glove box 16 has a first placement position, and the first placement position is used to place the first material transport barrel 12. The first material transport barrel 12 containing UO2 powder is heavy. In order to facilitate the staff to move the first material transport barrel 12, the suction unit 1 also includes a material transport trolley 11, and the material transport trolley 11 is used to place the first material transport barrel 12. The material transport trolley 11 can carry the first material transport barrel 12 in and out of the first operating glove box 16, so that the staff can more conveniently transport larger material containers, saving time and effort. In actual situations, the first operating glove box 16 has a first sealing door that can be opened and closed. The opened first sealing door can allow the material transport trolley 11 to enter and exit the first operating glove box 16, and after the first sealing door is closed, the first operating glove box 16 is a sealed environment to ensure the sealing of the UO2 powder suction process.

[0041] The suction assembly includes a first suction device, which is used to suck the UO2 powder in the first material transport barrel 12. The first suction device is placed in the first material transport barrel 12 for suction, and then the powder is transported to the receiving barrel 23.

[0042] In actual conditions, the first operating glove box 16 is provided with a first glove mounting hole 17, in which a first sealing glove is mounted, and the first glove mounting hole 17 is located above the discharge port of the first material transport barrel 12. The operator can put his hand into the first sealing glove in the first glove mounting hole 17 to operate the first material transport barrel 12 and the first suction device, for example, putting the suction end of the first suction device into the first material transport barrel 12, and moving the suction end of the first suction device out of the first material transport barrel 12.

[0043] refer to Figure 2In order to facilitate the suction end of the first suction device to enter and exit the first material transport barrel 12, the first suction device needs to move up and down. The first suction device includes a suction gun 14 and a telescopic part 19. The telescopic part 19 is arranged on the outside of the suction gun 14. The suction gun 14 and the telescopic part 19 have a first state and a second state. In the first state, the telescopic part 19 is stretched, and the suction end of the suction gun 14 is located outside the first material transport barrel 12. At this time, the suction gun 14 stops sucking materials and can provide moving space for the first material transport barrel 12 to enter and exit the first operating glove box 16; in the second state, the telescopic part 19 is compressed, and the suction end of the suction gun 14 is located inside the first material transport barrel 12, and the suction gun 14 sucks materials.

[0044] refer to Figure 2 The first end of the telescopic member 19 is fixedly connected to the outer side surface of the top surface of the first operating glove box 16, ensuring the stability of the telescopic member 19 and the suction gun 14 during movement. The second end of the telescopic member 19 is fixedly connected to the non-suction end of the suction gun 14, so that the telescopic member 19 can follow the suction gun 14 or drive the suction gun 14 to move up and down, thereby sucking the UO2 powder in the first material transport barrel 12.

[0045] Among them, the telescopic part 19 can be a telescopic cylinder, the cylinder body of the telescopic cylinder is fixedly connected to the outer side surface of the top surface of the first operating glove box 16, and the piston rod of the telescopic cylinder is fixedly connected to the non-suction end of the suction gun 14, and the suction gun 14 is driven up and down by the telescopic cylinder. The telescopic part 19 can also be a telescopic tube. Exemplarily, the telescopic tube is a damping telescopic tube. The operator puts his hand into the first sealing glove to pull the suction gun 14 into the first material transport barrel 12. Under the action of the damping telescopic tube, the suction gun 14 can be stabilized in the desired position to perform the suction operation. After the suction is completed, the operator puts his hand into the first sealing glove to pull the suction gun 14 upward away from the first material transport barrel 12, thereby facilitating the first material transport barrel 12 to enter and exit the first operating glove box 16. The telescopic part 19 can also be a telescopic spring or other telescopic component. The embodiment of the present application does not limit the type of the telescopic part 19.

[0046] In other embodiments, the material transport container further includes a second material transport bucket 13, and the first operating glove box 16 has a second placement location for placing the second material transport bucket 13. Exemplarily, the second placement location includes a placement table having a predetermined height, capable of accommodating the second material transport bucket 13. This allows a smaller second material transport bucket 13 to be placed on the placement table, facilitating suction of the smaller material transport container. It should be noted that the second material transport bucket 13 is smaller than the first material transport bucket 12.

[0047] Of course, the second placement position may not be provided with a placement table, and the second placement position and the first placement position may be distributed at the same height. In this case, if the second placement position is to place a second material transport bucket 13 with a smaller volume, the second suction device mentioned below needs to be longer.

[0048] The suction assembly includes a second suction device, which is used to suck up the UO2 powder from the second material delivery bucket 13. In practice, the first operating glove box 16 is also provided with a second glove mounting hole 18, into which a second sealing glove is mounted. The second glove mounting hole 18 is located above the discharge port of the second material delivery bucket 13. The operator can insert the second sealing glove into the second glove mounting hole 18 to operate the second material delivery bucket 13 and the second suction device. For example, the suction end of the second suction device can be placed into the second material delivery bucket 13 and removed from the second material delivery bucket 13.

[0049] Exemplary, reference Figure 2 The second suction device is a suction hose 15. When sucking the UO2 powder in the second material transport barrel 13, the operator puts his hand into the second sealing glove, puts the suction hose 15 into the inside of the second material transport barrel 13, and performs suction operations through the suction hose 15; when the suction is stopped, the operator puts his hand into the second sealing glove, takes the suction hose 15 out of the second material transport barrel 13, so that the second material transport barrel 13 can be removed or replaced.

[0050] In actual situations, the structures of the first suction device and the second suction device can be interchangeable, or the structures of the first suction device and the second suction device are the same, and the present invention is not limited to the embodiment in which the structures of the first suction device and the second suction device are different.

[0051] In some other embodiments, the material transport container further comprises a third material transport barrel, and the first operating glove box 16 has a third placement position for placing the third material transport barrel. The material suction assembly comprises a third suction device, which can suck the UO2 powder in the third material transport barrel.

[0052] refer to Figure 1 The suction unit 1 further includes a first conveying pipe 112, which connects the first suction device and the vacuum conveyor 111 and is provided with a first conveying valve 114; and a second conveying pipe 113, which connects the second suction device and the vacuum conveyor 111 and is provided with a second conveying valve 115. When the suction operation is performed, the vacuum conveyor 111 is started, and the first and second suction devices can be selected to suction the material separately or simultaneously. By opening or closing the corresponding conveying valves, the first and second suction devices can be controlled to suction the material, thereby achieving the suction of UO2 powder from the corresponding material transport container.

[0053] refer to Figure 3-Figure 4 In order to facilitate the stable connection between the docking mechanism 3 and the material receiving barrel 23 and provide the material receiving barrel 23 with a moving space to enter and exit the second operating glove box 21, the docking mechanism 3 also includes a telescopic cylinder 32. The docking mechanism 3 includes a first state and a second state. In the first state, the telescopic cylinder 32 drives the docking tube 31 away from the material receiving barrel 23, thereby providing the material receiving barrel 23 with a moving space to enter and exit the second operating glove box 21; in the second state, the telescopic cylinder 32 drives the discharge port of the docking tube 31 to dock with the material receiving port of the material receiving barrel 23, and the discharge port of the docking tube 31 is provided with a sealing structure. The discharge port of the docking tube 31 is sealed with the material receiving port of the material receiving barrel 23 through the sealing structure, further ensuring the sealing of the unloading process.

[0054] Exemplary, reference Figure 4 The telescopic cylinder 32 is arranged on the outside of the docking tube 31, and the docking tube 31 includes a fixed section and a telescopic section. The fixed section of the docking tube 31 is fixed in length, and the fixed section of the docking tube 31 is docked with the vacuum conveyor 111. The telescopic section of the docking tube 31 can be telescoped along the axial direction of the docking tube 31, and the telescopic section of the docking tube 31 is docked with the material receiving barrel 23. The cylinder body of the telescopic cylinder 32 is fixedly connected to the fixed section of the docking tube 31, thereby ensuring the stability of the telescopic section of the docking tube 31 driven by the telescopic cylinder 32 during the telescopic extension and retraction process. The piston rod of the telescopic cylinder 32 is fixedly connected to the telescopic section of the docking tube 31, and the telescopic section of the docking tube 31 is driven to extend and retract by the piston rod of the telescopic cylinder 32, thereby realizing the docking or distance between the docking tube 31 and the material receiving barrel 23.

[0055] Exemplary, reference Figure 5 The sealing structure provided at the discharge port of the butt joint pipe 31 may be a sealing air bag 33 , which seals the butt joint pipe 31 and the receiving barrel 23 .

[0056] Of course, the sealing structure can also be a rubber ring, a thermoplastic elastic ring, etc., and the embodiments of the present application do not limit this.

[0057] refer to Figure 3The receiving unit 2 also includes a platform scale 24 placed on the ground, with the receiving bucket 23 located on the platform scale 24. The platform scale 24 is used to connect the UO2 powder in the receiving bucket 23 to the platform scale 24 for weighing, packaging, and weight control. The platform scale 24 is sealed with the second operating glove box 21. Specifically, the platform scale 24 is a low-top platform scale with a slope on one side. Because the receiving bucket 23 is heavy after being loaded with UO2 powder, casters are provided at the bottom of the receiving bucket 23 to facilitate the movement of the receiving bucket 23 by the staff. The receiving bucket 23 can be moved in and out of the second operating glove box 21 along the slope of the platform scale 24 via the casters, making it convenient for the staff to move and replace the receiving bucket 23, saving time and effort. In actual practice, the second operating glove box 21 has a second sealing door that can be opened and closed. The opened second sealing door allows the receiving bucket 23 to enter and exit the second operating glove box 21. After the second sealing door is closed, the second operating glove box 21 is sealed to ensure the sealing of the UO2 powder unloading process.

[0058] refer to Figure 3 The receiving unit 2 also includes an electrical control box 25, to which the platform scale 24 and the vacuum conveyor 111 are electrically connected. When the weight of the UO2 powder in the receiving bucket 23 reaches a set value, the electrical control box 25 controls the vacuum conveyor 111 to automatically stop and start sucking the material. After that, a new receiving bucket 23 is replaced and the vacuum conveyor 111 is started again to suck the material.

[0059] When the UO2 powder transfer device is working, the staff first places the material transport container and the receiving barrel 23 in the corresponding placement positions, starts the telescopic cylinder 32 to seal the discharge port of the docking pipe 31 with the receiving port of the receiving barrel 23, places the suction component in the corresponding material transport container, opens the corresponding conveying valve, and starts the vacuum conveyor 111. Then the suction component sucks the UO2 powder in the material transport container, and the UO2 powder passes through the corresponding conveying pipe and is transported to the receiving barrel 23 through the docking pipe 31. The platform scale 24 monitors the weight of the UO2 powder in the docking barrel 23. When the weight of the UO2 powder in the receiving barrel 23 reaches the set value, the electrical control box 25 controls the vacuum conveyor 111 to automatically stop sucking the material, completing the transfer of UO2 powder once, and then replacing the receiving barrel 23. The UO2 powder transfer operation can be repeated; after the UO2 powder in the material transport container is transferred, the material transport container is replaced and the UO2 powder transfer operation can be continued.

[0060] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
