Description

Technical Field

[0001] This invention belongs to the field of nuclear power spent fuel reprocessing technology, specifically relating to a capping device and a solid waste filling system. Background Technology

[0002] During the production and operation of nuclear power plants, spent fuel reprocessing facilities, a large amount of radioactive solid waste is generated. By using methods such as compression and volume reduction, and combustion, the waste can be minimized and disposal costs reduced.

[0003] The compressed cakes produced from the volume reduction of high-level radioactive solid waste need to be filled into cake containers for temporary packaging and storage, pending subsequent disposal. Because the hot chambers used in the volume reduction process of high-level radioactive solid waste have high radioactivity, filling the same hot chamber would contaminate the outer surface of the cake container. Therefore, the volume reduction device and the cake container supply device must be located in different hot chambers. A cake filling channel needs to be provided between the two hot chambers. This channel must be shielded and sealed when not in use. The cake containers have lids; these must be removed before filling and replaced after filling. Therefore, a device is needed that provides shielding and sealing, and also allows for the removal and resealing of the cake container lids. Currently, there is no such device for radioactive solid waste filling systems. Summary of the Invention

The lifting claws of the lifting device are in their maximum open and locked state. When the lifting device lifts the pressing container and the lid of the pressing container contacts the lifting claw seat, the lifting device continues to rise. The guide shaft is lifted by the lifting claw seat, and the shaft follows the guide shaft upward and rotates 45° along the groove, stopping when it reaches the concave surface of the upper toothed sleeve's serrations.

The side of the lower end of the guide shaft 25 where it connects with the locking block 41 is T-shaped. The two are connected to form a T-head. The lower end face of the locking block 41 is rectangular. When the long side of the rectangle is parallel to the long side of the rectangular hole, the locking block 41 can enter and exit the circular hole below. When the locking block 41 is rotated 45°, the locking block 41 will not be able to come out of the circular hole upwards.

[0073] like Figure 7 As shown, the pressing container 4 includes a lid 37 and a body 38, with the lid 37 placed on the body 38.

[0074] like Figure 1As shown, this embodiment also provides a solid waste filling system, including: a cake-forming optimization platform 2, a height-measuring cake-filling device 1, the aforementioned cap-removing device 3, a cake-forming container 4, and a lifting device 5. The height-measuring cake-filling device 1 and the cake-forming optimization platform 2 are arranged in the first hot chamber 8. The cake-forming optimization platform 2 is used for temporary storage and optimized proportioning of cakes 6. The cakes 6 are cakes formed from compressed and reduced-volume solid waste. The cakes 6 are placed on the cake-forming optimization platform 2. The height-measuring cake-filling device 1 is used for measuring the height of the cakes, gripping the cakes, and removing them. The sealing device 3 and the height measuring and filling device 1 are also used to push the pressed cake into the pressed cake container. The lifting device 5 is arranged in the second hot chamber 9. The pressed cake container 4 is placed on the lifting device 5 and is used to hold the pressed cake 6. The first hot chamber 8 is located above the second hot chamber 9. A channel 7 is provided between the first hot chamber 8 and the second hot chamber 9. The channel 7 is blocked by the sealing device 3. The sealing device 3 shields and seals the first hot chamber 8 and the second hot chamber 9. The sealing device 3 is used to perform the sealing operation on the pressed cake container.

[0075] Channel 7 is the filling channel. The cap removal device 3 has a non-powered lifting device. Before filling the compressed cake, the lifting device 5 raises the compressed cake container and aligns it with the bottom of the cap removal device 3. When the height-measuring filling device 1 lifts the cap removal device 3, the cap removal device 3 can remove the cap from the compressed cake container. The compressed cake container is used to hold the compressed cake. Its structure is adapted to the compressed cake and meets the requirements for solid waste disposal. After filling, the compressed cake is stable and does not shake inside the compressed cake container. The lifting device 5 has a built-in compressed cake container bracket, which can realize the lifting of the compressed cake container to align with the cap removal device 3 before filling, and the lowering of the compressed cake container after filling.

[0076] Preferably, the pressing table 2 is provided with a notch station, and the other stations are for placing the pressing table 6 and the sealing device 3. The pressing table 2 is a rotary table.

[0077] Specifically, the preferred pressing table 2 is a circular rotary table, which is equally divided into twelve workstations, one of which is the notch workstation, and the other eleven are the placement workstations for the pressing table 6 and the sealing device 3.

[0078] The workflow of the solid waste filling system is as follows: The compressed cakes are prepared on the compressed cake selection platform 2, and the height-measuring cake loading device 1 has completed the measurement of the compressed cake height. The lifting device 5 lifts the compressed cake container. After lifting to the correct position, the height-measuring cake loading device 1 lowers, and the gripper grabs the movable part of the cap-removing device 3, placing it on the empty position of the compressed cake selection platform 2. The lid 37 of the compressed cake container is removed along with the movable part of the cap-removing device 3. After the lid is removed, the height-measuring cake loading device 1 grabs the compressed cakes on the compressed cake selection platform 2 and places them into the compressed cake container. After all the selected compressed cakes are filled into the compressed cake container, the height-measuring cake loading device 1 grabs the movable part of the cap-removing device 3 and the lid 37 from the compressed cake selection platform 2, placing them back on the pre-embedded base of the cap-removing device 3. The lifting device 13 automatically opens, and the lid 37 falls onto the barrel 38 of the compressed cake container. The lifting device lowers, removing the compressed cake container from the channel 7. This completes the filling of one compressed cake container.

[0079] like Figure 8 As shown, specifically, when the capping device 3 is placed in the channel 7 between the first hot chamber 8 and the second hot chamber 9, under the weight of the lifting device 13, the lifting claw 31 is in a fully open state, and the long side of the T-shaped locking block 41 connected to the guide shaft 25 is parallel to the long side of the rectangular hole of the lifting claw seat 29.

[0080] Before removing the lid, when the lifting device 13 is in its initial state, the shaft 35 is positioned at the concave surface of the serrated edge of the lower gear sleeve 36, and the locking block 41 at the lower end of the guide shaft 25 is located in the second hole of the lifting claw seat 29 and is perpendicular to the first hole 44. The lifting claw 31 of the lifting device 13 is in its maximum open and locked state. Before filling, the pressing container 4 is lifted by the lifting device 5. When the lid 37 of the pressing container 4 contacts the lifting claw seat 29, the lifting device 5 continues to rise, the guide shaft 25 is lifted by the lifting claw seat 29, and the shaft 35 rises with the guide shaft 25 and rotates 45° along the groove 40, stopping when it reaches the concave surface of the serrated edge of the upper gear sleeve 26. The locking block 41 rotates 45° with the shaft 35 in the second hole of the lifting claw seat 29. At this time, the locking block 41 is at a 45° angle to the first hole 44 of the lifting claw seat 29. When the lid 37 contacts the protective cover 17, the spring 16 buffers the pressing container 4, and the lifting device 5 stops.

[0081] When removing the lid, the height-measuring and filling device 1 descends. When it reaches the lower limit, it grabs the mushroom-shaped handle of the shielding plug 11. Then, the height-measuring and filling device 1 moves upward, lifting the entire movable part of the lid-removing device 3. The lifting eye screw 12, the first lifting eye 22, the chain 23, and the second lifting eye 24 move upward together with the shielding plug 11. When the chain 23 is extended to its longest length, the second lifting eye 24, the upper toothed sleeve 26, and the guide sleeve 27 also move upward together. The connecting rod 30 rotates around the pins 32 and 33, thereby driving the lifting claw 31 to rotate inward and retract around the pin 34. At the same time, the shaft 35 moves along the groove 40, and the guide shaft 25 rotates 90° and moves upward. The long side of the locking block 41 connected to the guide shaft 25 is parallel to the short side of the rectangular hole of the lifting claw seat 29. The locking block 41 will not come out of the circular hole of the lifting claw seat 29, which can make the lifting device 13 self-locking. After the lifting claw 31 is fully retracted, it grabs the lid 37 and moves upward. Guide sleeve 27, upper gear sleeve 26, and lower gear sleeve 36 move upwards, and shaft 35 rotates 45° again along groove 40, reaching the concave surface of the serration of lower gear sleeve 36. At this time, locking block 41 is parallel to the first hole 44 of lifting claw seat 29. Connecting rod 30 and lifting claw 31 rotate around pin 32, pin 33, and pin 34 respectively. Lifting claw 31 retracts inward and grabs the lid 37 of pressing container 4. The movable part of lid removal device 3 continues to rise, guide shaft 25 rises with guide sleeve 27, locking block 41 disengages from the first hole 44 of lifting claw seat 29, and lid 37 is lifted along with the movable part of lid removal device 3.

[0082] After the height measuring and filling device 1 reaches its upper limit, it stops. The pressing and selecting platform 2 rotates, moving an empty workstation where the cap-removing device 3 is placed directly below the height measuring and filling device 1. The height measuring and filling device 1 drives the movable part of the cap-removing device 3 and the barrel cover 37 downwards. The barrel cover 37 stops when it contacts the pressing and selecting platform 2, placing the movable part of the cap-removing device 3 and the barrel cover 37 on the pressing and selecting platform 2. At this time, under the action of gravity, the upper toothed sleeve 26 and the guide sleeve 27 of the lifting device 13 will move downwards, driving the connecting rod 30 and the lifting claw 31 to rotate and open. At the same time, the shaft 35 moves along the groove 40, the guide shaft 25 rotates 90°, and the long side of the locking block 41 connected to the guide shaft 25 is parallel to the long side of the rectangular hole of the lifting claw seat 29 again.

[0083] After the lid is removed, the pressing platform 2 rotates, and the pressed cake 6 is rotated sequentially to the direct below the height measuring and filling device 1, and the pressed cake 6 is filled into the pressing container.

[0084] After filling, during the sealing process, the pressing platform 2 rotates, positioning the movable part of the sealing device 3 and the barrel lid 37 directly below the height measuring and filling device 1. The height measuring and filling device 1 descends to grab the handle of the shielding plug 11 of the sealing device 3, then rises to lift the entire movable part of the sealing device 3 and the barrel lid 37. During the upward movement of the lifting device 13, the lifting claw 31 rotates inward to retract, while the guide shaft 25 rotates 90° to achieve self-locking retraction of the lifting device 13. The self-locking working principle is the same as described above. The lifting device 13 lifts the barrel lid 37 and moves upward together. After reaching the upper limit, the height measuring and filling device 1 stops. The pressing and selecting platform 2 rotates again, rotating the notch position of the pressing and selecting platform 2 to be directly below the height measuring and filling device 1. The height measuring and filling device 1 moves downward, driving the moving part of the sealing device 3 and the barrel lid 37 to move downward until the barrel lid 37 contacts the barrel body 38 of the pressing container 4. The height measuring and filling device 1 continues to descend, and the guide sleeve 27, upper toothed sleeve 26, and lower toothed sleeve 36 move downward. The guide shaft 25 follows the guide sleeve 27 downward, and the locking block 41 returns to the second hole of the lifting claw seat 29. The shaft 35 rotates 45° along the groove 40 to the concave surface of the sawtooth of the lower toothed sleeve 36. The locking block 41 is at a 45° angle to the first hole 44 of the lifting claw seat 29. The connecting rod 30 and the lifting claw 31 rotate around the pin 32, pin 33, and pin 34 respectively. The lifting claw 31 opens outward to the maximum opening state, and the lifting claw 31 releases the barrel lid 37. The sealing device 3 stops when the shielding plug 11 lands on the step of the pre-embedded seat 10, and the bucket lid 37 lands on the bucket body 38. Under the action of gravity, the lifting claw 31 of the lifting device 13 rotates outward and opens, completing the sealing.

[0085] The lifting device 5 descends, causing the pressing container 4 to descend as well. The lifting claw seat 29 falls, pressing down the guide shaft 25. The shaft 35 follows the guide shaft 25 and rotates 45° along the groove 40, stopping when it reaches the concave surface of the serrated teeth of the lower toothed sleeve 36. The locking block 41 rotates 45° with the shaft 35, at which point the locking block 41 is located in the second hole of the lifting claw seat 29 and is perpendicular to the first hole 44. The lifting device 5 then lowers the pressing container 4, which is filled with pressing cake 6, back to its original position, completing the entire filling process.

[0086] This embodiment provides a cap removal and sealing device and a solid waste filling system. The cap removal and sealing device is a multi-functional integrated design that can not only shield and seal between two hot chambers, but also remove and seal the compressed cake container.
