Description

Technical Field

[0001] This invention relates to the field of radioactive waste treatment technology, and in particular to a system and method for collecting and packaging radioactive incineration ash. Background Technology

[0002] In radioactive waste incineration processes, incineration ash accumulates at the bottom of equipment such as incinerators, secondary combustion chambers, quench towers, and bag filters. This necessitates the unloading and collection of the generated ash. Currently, ash unloading in radioactive waste incineration processes typically involves using an ash discharger. Ash collection is achieved by transporting metal ash containers to a glove box, removing the lids from the containers inside the glove box, and then placing them under the ash discharge port. The ash discharge valve and ash discharger are then opened to discharge the ash into the metal ash containers. Observation is maintained until the metal ash containers are nearly full, at which point the ash discharger and valve are closed. After unloading, the metal ash containers are finally sealed for subsequent transfer, temporary storage, and processing.

[0003] Currently, radioactive waste incineration processes suffer from several problems, including low automation in ash collection and unloading, defects in metal ash bin connections, severe dust generation from incineration ash, internal contamination of metal ash bins, and difficulties in reuse. Because incineration ash possesses a certain degree of radioactivity, the sealing and safety requirements for the ash discharge system are even higher.

[0004] Therefore, it is necessary to design an automated ash unloading, collection, and packaging method to effectively reduce personnel working hours and exposure time, and protect personnel health. Summary of the Invention

[0042] S1. The metal ash bucket is placed on the first roller conveyor and transported to the first sealed chamber through the first roller conveyor, the open first sealing door and the second roller conveyor. When the metal ash bucket reaches the lid pick-up and put-down station, the first roller conveyor and the second roller conveyor stop rotating; the first sealing door closes.

[0043] S2. Inside the first sealed chamber, the lid-removing mechanism removes the lid from the metal ash bucket;

[0044] S3. The second sealing door opens, and the metal ash bucket is conveyed to the second sealing chamber through the second roller conveyor and the third roller conveyor. When the metal ash bucket reaches the unloading and packaging station, the second roller conveyor and the third roller conveyor stop rotating; the second sealing door closes; S4. The packaging device is started to heat-seal the packaging film into a film bag and place it into the metal ash bucket;

[0045] S5. The incineration ash is unloaded into the membrane bag through the feeding pipe. After the membrane bag is filled with a predetermined weight of incineration ash, the packaging device heat-seals and cuts the membrane bag.

[0046] S6. The second sealing door opens, and the third roller conveyor and the second roller conveyor reverse their directions to send the metal ash bucket filled with ash back to the first sealing chamber.

[0049] Preferably, in step S3, after the metal ash bucket arrives at the unloading and packaging station, the lifting mechanism below the third roller conveyor is activated to lift the metal ash bucket and weigh it using a weighing sensor.

[0050] In step S5, the incineration ash is discharged into the membrane bag inside the metal ash bucket through the discharge pipe. When the weight of the metal ash bucket obtained by the weighing sensor reaches the predetermined weight, the discharge pipe stops discharging ash.

[0051] The beneficial effects of this invention are as follows: By coordinating the sealed chamber and its internal loading and unloading cover mechanism, feeding pipe and packaging device, radioactive incineration ash is packaged into bags in the sealed chamber and placed into a metal ash bucket. The whole process is automated, and personnel do not need to come into contact with the incineration ash, thus reducing personnel exposure levels. The packaged incineration ash is less likely to leak out, which facilitates subsequent transportation, temporary storage and disposal. Attached Figure Description

[0062] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0063] like Figure 1 , Figure 2 As shown, a radioactive incineration ash collection and packaging system according to an embodiment of the present invention includes a first sealed chamber 10, a second sealed chamber 20, a conveying mechanism, a cover-removing mechanism 40, a discharge pipe 50, and a packaging device. It also includes a control box 100, which is connected to the conveying mechanism, the cover-removing mechanism 40, the discharge pipe 50, and the packaging device, and controls the opening and closing, mode, etc. of the conveying mechanism, the cover-removing mechanism 40, the discharge pipe 50, and the packaging device.

[0064] The first sealed chamber 10 and the second sealed chamber 20 provide sealed operating spaces for the metal ash container 200, facilitating the removal of the lid and the unloading of radioactive incineration ash into the metal ash container 200 within these sealed spaces. The first sealed chamber 10 and the second sealed chamber 20 are arranged adjacent to each other. The first sealed chamber 10 is used for operations such as removing and closing the lid of the metal ash container 200, while the second sealed chamber 20 is used for ash unloading operations, specifically for unloading incineration ash into the metal ash container 200. A first sealed door 11 is located on the side of the first sealed chamber 10 facing away from the second sealed chamber 20, and a second sealed door 12 is located between the first sealed chamber 10 and the second sealed chamber 20. The first sealed chamber 10 is connected to or isolated from the external environment through the opening and closing of the first sealed door 11, facilitating the insertion and removal of the metal ash container 200; the first sealed chamber 10 and the second sealed chamber 20 are connected or isolated through the second sealed door 12.

[0065] The conveying mechanism is used to transport the metal ash bucket 200 sequentially into the first sealed chamber 10 and the second sealed chamber 20, and also to deliver the metal ash bucket 200 after it has been filled with ash out of the second sealed chamber 20 and the first sealed chamber 10. The lid-removing mechanism 40 is located in the first sealed chamber 10 and is used to pick up or put back the lid 210 on the metal ash bucket 200. The discharge pipe 50 is located in the second sealed chamber 20 and is used to transport the incineration ash into the film bag inside the metal ash bucket 200. The packaging device is located on the second sealed chamber 20 and is used to form the packaging film into a film bag and place it into the metal ash bucket 200. After the film bag is filled with incineration ash, it is heat-sealed and cut open, solving the problems of contamination inside the metal ash bucket 200 and the sealing issues.

[0066] Specifically, the first sealed chamber 10 and the second sealed chamber 20 can be formed within a sealed box. In one embodiment, the radioactive incineration ash collection and packaging system of the present invention can enclose a first sealed box 110 and a second sealed box 120 connected to each other, with the first sealed chamber 10 and the second sealed chamber 20 respectively formed within the first sealed box 110 and the second sealed box 120. A second sealing door 12 is disposed on the connecting side wall of the first sealed box 110 and the second sealed box 120, while a first sealing door 11 is disposed on the side wall of the first sealed box 110. In another embodiment, the radioactive incineration ash collection and packaging system of the present invention can include a sealed box (not shown), with the first sealed chamber 10 and the second sealed chamber 20 respectively formed within the sealed box, connected or isolated by the opening and closing of the second sealing door 12, and the first sealing door 11 disposed on the side wall corresponding to the first sealed chamber 10.

[0067] The first sealing door 11 and the second sealing door 12 are sealed by using an inflatable gasket. After the first sealing door 11 or the second sealing door 12 is closed, the gasket inflates and expands, contacting the first sealing door 11 or the second sealing door 12 to form a seal.

[0068] To facilitate observation of the conditions inside the first sealed chamber 10 and the second sealed chamber 20 by staff, at least one side wall of the first sealed chamber 10 may be provided with a first viewing window 101, and at least one side wall of the second sealed chamber 20 may be provided with a second viewing window 201. The first viewing window 101 and the second viewing window 201 may each be formed of glass. Illumination lamps may be provided inside the first sealed chamber 10 and the second sealed chamber 20.

[0069] In addition, a first protective glove 102 may be provided on the first viewing window 101 to facilitate personnel in adjusting and maintaining the equipment inside the first sealed chamber 10. When components inside the first sealed chamber 10 malfunction, such as a failure of the cover-removing mechanism 40, personnel can manually remove or place covers using the first protective glove 102. Similarly, a second protective glove 202 may be provided on the second viewing window 201 to facilitate manual operation of internal equipment.

[0070] Furthermore, the side wall of the first sealed chamber 10 may also be provided with an inspection port 103 and / or an inspection door, and the side wall of the second sealed chamber 20 may also be provided with an inspection port 203 and / or an inspection door.

[0071] The conveying mechanism may further include a first roller conveyor 31, a second roller conveyor 32, and a third roller conveyor 33 arranged sequentially on the conveying path of the metal ash bucket 200. The first roller conveyor 31 is located outside the first sealing door 11, while the second roller conveyor 32 and the third roller conveyor 33 are respectively located within the first sealing chamber 10 and the second sealing chamber 20. The second roller conveyor 32 has a cap-loading / placing station located below the cap-loading / placing mechanism 40; the third roller conveyor 33 has an ash-unloading and packaging station located below the discharge pipe 50. Before ash loading, the first roller conveyor 31 conveys the metal ash bucket 200 into the first sealing chamber 10, and in conjunction with the second roller conveyor 32, conveys the metal ash bucket 200 to the cap-loading / placing station within the first sealing chamber 10. The cooperation of the second roller conveyor 32 and the third roller conveyor 33 conveys the metal ash bucket 200 into the second sealing chamber 20, so that it can reach the ash-unloading and packaging station for ash loading. After the incineration ash is packaged into bags in the metal ash bucket 200, the third roller conveyor 33, the second roller conveyor 32 and the first roller conveyor 31 are conveyed in reverse order to send the metal ash bucket 200 out of the second sealed chamber 20, the first sealed chamber 10 and the outside of the first sealed chamber 10 in sequence.

[0072] Understandably, the first roller conveyor 31, the second roller conveyor 32 and the third roller conveyor 33 can be formed by arranging multiple rollers, and can be supported by brackets at a certain height.

[0073] Inside the first sealed chamber 10, in order to position the metal ash bucket 200 after it arrives at the cap-retrieving station and facilitate the cap-retrieving mechanism 40 to retrieve the cap, a first limiting mechanism 71 is provided on the second roller conveyor 32. This first limiting mechanism 71 is located on the side of the cap-retrieving station facing the third roller conveyor 33 and is communicatively connected to the first roller conveyor 31 and the second roller conveyor 32. After the metal ash bucket 200 is conveyed to the cap-retrieving station via the first roller conveyor 31 and the second roller conveyor 32 and triggers the first limiting mechanism 71, the first roller conveyor 31 and the second roller conveyor 32 stop rotating.

[0074] In this embodiment, as Figure 2 and Figure 3As shown, the first limiting mechanism 71 includes a first stop 711 that can extend vertically onto the second roller conveyor 32, a first trigger 713 disposed on the first stop 711, and a first cylinder 712 connected to and driving the first stop 711 to move vertically. The first cylinder 712 is disposed below the second roller conveyor 32. The first cylinder 712 has its telescopic rod facing upward. After activation, the telescopic rod extends upward, causing the first stop 711 on it to protrude onto the second roller conveyor 32. The first stop 711 can block the metal ash bucket 200 in the direction of travel, restricting the metal ash bucket 200 from continuing to move forward. The first trigger 713 is disposed on the side of the first stop 711 facing the metal ash bucket 200. It is triggered after contacting the metal ash bucket 200, and the trigger signal controls the first roller conveyor 31 and the second roller conveyor 32 to stop the conveying operation. When the metal ash bucket 200 needs to continue to move onto the third roller conveyor 33, the telescopic rod of the first cylinder 712 moves downward, causing the first stop 711 to retract below the second roller conveyor 32.

[0075] Alternatively, the first stop 711 can be a rod or a plate that extends through the gap between the rollers onto the second roller conveyor 32. The first trigger 713 can be a trigger switch, a sensor, etc.

[0076] Similarly, in order to position the metal ash bucket 200 after it arrives at the lid-picking and placing station, and to facilitate the lid-picking and placing mechanism 40 to close the lid 210 onto the metal ash bucket 200, a second limiting mechanism 72 is also provided on the second roller conveyor 32. This second limiting mechanism 72 is located on the side of the lid-picking and placing station facing the first roller conveyor 31, and is communicatively connected to the second roller conveyor 32 and the third roller conveyor 33. After the metal ash bucket 200 is conveyed to the lid-picking and placing station by the third roller conveyor 33 and the second roller conveyor 32 and triggers the second limiting mechanism 72, the third roller conveyor 33 and the second roller conveyor 32 stop rotating.

[0077] The second limiting mechanism 72 may include a second stop 721 that can extend vertically onto the second roller conveyor 32, a second trigger 723 disposed on the second stop 721, and a second cylinder 722 connected to and driving the second stop 721 to move vertically. The second cylinder 722 is disposed below the second roller conveyor 32. The second cylinder 722 is configured with its telescopic rod facing upward. After activation, the telescopic rod extends upward, causing the second stop 721 to protrude onto the second roller conveyor 32. The second stop 721 can block the metal ash bucket 200 in the direction of travel, restricting the metal ash bucket 200 from continuing to move forward. The second trigger 723 is disposed on the side of the second stop 721 facing the metal ash bucket 200. It is triggered after contacting the metal ash bucket 200, and the trigger signal controls the second roller conveyor 32 and the third roller conveyor 33 to stop the conveying operation. When the metal ash bucket 200 needs to continue moving forward onto the first roller conveyor 31, the telescopic rod of the second cylinder 722 moves downward, causing the second stop 721 to retract below the second roller conveyor 32.

[0078] Alternatively, the second stop 721 can be a rod or a plate that extends onto the second roller conveyor 32 through the gap between the rollers. The second trigger 723 can be a trigger switch, a sensor, etc.

[0079] The first cylinder 712 and the second cylinder 722 are located at the bottom of the first sealed chamber 10. The inspection port 103 can be set on the lower end of the side wall of the first sealed chamber 10 to facilitate the maintenance of components such as the first cylinder 712 and the second cylinder 722.

[0080] In addition, when the second roller conveyor 32 has a large width, in order to ensure that the metal ash bucket 200 is centered below the cap picking and placing mechanism 40 after it arrives at the cap picking and placing station, a limiting guide mechanism is provided on at least one side of the second roller conveyor 32 along the length direction to limit the metal ash bucket 200 on the straight path of the cap picking and placing station.

[0081] The limiting and guiding mechanism may specifically include a vertically arranged baffle 321 and multiple rollers 322 that are in contact with and can roll on the outer surface of the metal ash bucket 200; the multiple rollers 322 are arranged at intervals along the length of the baffle 321. When the metal ash bucket 200 moves on the second roller conveyor 32, its outer surface can contact the rollers 322, and the two can slide relative to each other to ensure the movement of the metal ash bucket 200.

[0082] In this embodiment, the lid-removing mechanism 40 includes a drive unit 41 and an electromagnet 42. The electromagnet 42 is magnetic when energized, used to lift the lid 210 of the metal ash bin 200. When de-energized, the electromagnet 42 is demagnetized, allowing the lid 210 to be placed back onto the metal ash bin 200. The drive unit 41 drives the electromagnet 42 to move up and down, closer to or further away from the metal ash bin 200.

[0083] The drive unit 41 can be implemented by a cylinder, with its telescopic drive rod facing the second roller conveyor 32, and an electromagnet 42 disposed at the end of the drive rod. After the drive unit 41 is started, the drive rod drives the electromagnet 42 to move downwards and approach the metal ash bin 200. When the electromagnet 42 is energized, it can pick up the lid 210 of the metal ash bin 200.

[0084] In the second sealed chamber 20, in order to position the metal ash bucket 200 after it arrives at the unloading and packaging station, a third limiting mechanism 73 is provided on the third roller conveyor 33. The third limiting mechanism 73 is located on the side of the unloading and packaging station away from the second roller conveyor 32, and is communicatively connected to the third roller conveyor 33 and the second roller conveyor 32. After the metal ash bucket 200 is conveyed to the unloading and packaging station by the second roller conveyor 32 and the third roller conveyor 33 and triggers the third limiting mechanism 73, the second roller conveyor 32 and the third roller conveyor 33 stop rotating.

[0085] The third limiting mechanism 73 may specifically include a baffle 731 disposed on or outside the third roller conveyor 33, and a third trigger 732 disposed on the baffle 731. When the metal ash bucket 200 has traveled to its position on the third roller conveyor 33, the baffle 731 contacts the outer surface of the metal ash bucket 200, restricting the metal ash bucket 200 from continuing to travel. At the same time, the third trigger 732 on the baffle 731 also detects the metal ash bucket 200 and controls the second roller conveyor 32 and the third roller conveyor 33 to stop the conveying operation by sending a signal. The third trigger 732 may be a trigger switch or a limit sensor.

[0086] Of course, the third limiting mechanism 73 can also be set with reference to the structural form of the first limiting mechanism 71.

[0087] The feeding pipe 50 is vertically installed inside the second sealed chamber 20. The top end of the feeding pipe 50 is fixed to the top of the second sealed chamber 20, and the bottom end serves as the feeding port facing the third roller conveyor 33. The top opening of the feeding pipe 50 serves as the feeding end, receiving incineration ash from the incineration treatment system. The opening and closing of this feeding end is controlled by the ash discharge valve 51. The ash discharge and packaging station is located directly below the feeding pipe 50.

[0088] The packaging device is used to release the roll of packaging film and form it into a film bag 300, and to seal the film bag 300 (heat sealing and cutting) after filling. Specifically, as shown... Figure 2 , Figure 4 As shown, the packaging device includes a film feeding mechanism 61, a forming mechanism 62, a film conveying roller assembly 63, a longitudinal sealing mechanism 64, and a transverse sealing mechanism 65.

[0089] The film feeding mechanism 61 is located outside the second sealed chamber 20 and is used to hold the packaging film roll (roll-shaped packaging film) and feed the packaging film out in a strip form to the forming mechanism 62. The side wall of the second sealed chamber 20 may be provided with a channel opening to facilitate the packaging film passing through the channel opening to the forming mechanism 62.

[0090] refer to Figure 4 and Figure 5 The film feeding mechanism 61 may specifically include a housing 611, a feed roller 612 mounted on the housing 611, and a limiting shaft assembly. The film feeding mechanism 61 is fixed outside the second sealed chamber 20 by the housing 611. The feed roller 612 is rotatably mounted on the housing 611 and is used to place the packaging film roll. The limiting shaft assembly includes a plurality of limiting shafts 613, which are spaced apart in the feeding direction of the packaging film roll, so that the limiting shaft assembly cooperates with the feed roller 612 to place the packaging film onto the forming mechanism 62.

[0091] The forming mechanism 62 is located outside the upper end of the feeding tube 50, receives the packaging film released from the film feeding mechanism 61, and forms the packaging film into an annular film (cylindrical) around the outer periphery of the feeding tube 50.

[0092] The film conveying roller assembly 63 and the longitudinal sealing mechanism 64 are respectively located outside the feeding pipe 50 and below the forming mechanism 62. The film conveying roller assembly 63 conveys the annular film downwards along the outer circumference of the feeding pipe 50 through rollers and other components. The longitudinal sealing mechanism 64 is used to heat-seal both sides of the annular film in the longitudinal direction to form a closed cylindrical structure. The transverse sealing mechanism 65 is located below the longitudinal sealing mechanism 64 and is used to heat-seal the bottom of the annular film to form a film bag. It is also used to heat-seal the film bag 300 after it has been filled with incineration ash, thus achieving the packaging of incineration ash. The transverse sealing mechanism 65 has a cutter in the middle, which can cut the film bag 300 after heat-sealing.

[0093] Combination Figure 2 , Figure 6 and Figure 7 The film conveying roller assembly 63 includes a pressure roller 631, a pressure roller clamping unit 632, and a pulley drive unit 633. The pressure roller clamping unit 632 pushes the pressure roller 631 to press the packaging film (i.e., the annular film) between the pressure roller 631 and the surface of the feed tube 50. The pulley drive unit 633 drives the pressure roller 631 to rotate, and under the action of friction, pulls the packaging film along the feed tube 50 from top to bottom, thereby realizing the film conveying function.

[0094] The pressure roller clamping unit 632 can be implemented using a cylinder; the pulley drive unit 633 can be implemented using a motor.

[0095] The longitudinal sealing mechanism 64 includes a longitudinal heat sealer 641 and a longitudinal heat sealer driving unit 642. The longitudinal heat sealer 641 has a heating function, which can heat the pressure plate on the longitudinal heat sealer 641 to a certain temperature. The longitudinal heat sealer 641 is arranged along the axial direction of the feed pipe 50. The longitudinal heat sealer 641 is driven by the longitudinal heat sealer driving unit 642, which drives the pressure plate on the longitudinal heat sealer 641 to press the packaging film into the feed pipe 50. Under the action of pressure and high temperature, the packaging film melts and seals, completing the longitudinal sealing.

[0096] The film conveying roller assembly 63 and the longitudinal sealing mechanism 64 are mounted and positioned on the outer periphery of the feeding pipe 50 via a bracket. During operation, the film conveying roller assembly 63 and the longitudinal heat sealing machine 641 operate alternately. After the film conveying roller assembly 63 has transported the packaging film to the set length, it stops rotating. At this time, the longitudinal heat sealing machine 641 presses, heat-melts, and seals the packaging film.

[0097] Combination Figure 2 , Figure 6 , Figure 8 and Figure 9The horizontal sealing mechanism 65 may include a horizontal heat sealer 651, a horizontal heat sealer pushing unit 652, a cutter 653, and a cutter pushing unit 654. The horizontal heat sealer 651 includes an upper pressure plate and a lower pressure plate; the horizontal heat sealer has a heating function, capable of heating the upper and lower pressure plates of the horizontal heat sealer 651 to the required temperature. The horizontal heat sealers 651 are typically arranged in pairs and spaced apart, with the film bag passing between the two horizontal heat sealers 651. The horizontal heat sealer pushing unit 652 pushes the two horizontal heat sealers 651 to move towards each other, pressing the opening of the film bag tightly. Under pressure and high temperature, the film bag melts and seals, completing two horizontal seals.

[0098] The cutter 653 is built into one of the transverse heat sealers 651, and is located between the upper and lower pressure plates of the transverse heat sealer 651. After the transverse sealing is completed, the cutter 653 is pushed out by the cutter pusher unit 654 to cut the film bag.

[0099] The transverse sealing mechanism 65 is mounted in the second sealing chamber 20 via a bracket 67 and positioned below the longitudinal sealing mechanism 64. The transverse heat sealing machine pushing unit 652 and the cutter pushing unit 654 can be driven by cylinders.

[0100] In addition, the radioactive incineration ash collection and packaging system of the present invention may also include a lifting mechanism 80 for lifting the metal ash bucket 200 and a weighing sensor (not shown) for weighing the metal ash bucket 200. The lifting mechanism 80 is located below the third roller conveyor 33, and the weighing sensor is located on the lifting mechanism 80; after the lifting mechanism 80 lifts the metal ash bucket 200 away from the third roller conveyor 33, the weighing sensor weighs the metal ash bucket 200 to obtain its weight.

[0101] The lifting mechanism 80 may include a lifting drive unit 81 and a lifting support 82 installed below the third roller conveyor 33. The piston cylinder of the lifting drive unit 81 faces upward toward the third roller conveyor 33. The lifting support 82 is mounted on the piston cylinder of the lifting drive unit 81 and moves up and down with the extension and retraction of the telescopic rod, passing through the third roller conveyor 33 to lift the metal ash bucket 200. A weighing sensor may be mounted on the lifting support 82. The lifting drive unit 81 may be implemented using a cylinder or a motor in conjunction with a gear assembly, etc.

[0102] After the metal ash bucket 200 arrives at the ash unloading and packaging station, the lifting mechanism 80 is activated to lift the metal ash bucket 200 while simultaneously weighing it using a weighing sensor to obtain its net weight. During ash unloading through the discharge pipe 50, the weighing sensor continuously monitors the weight of the incineration ash in the inner membrane bag 300 of the metal ash bucket 200. When the weight of the metal ash bucket 200 reaches a predetermined weight, the signal from the weighing sensor controls the discharge valve 51 of the discharge pipe 50 to close, stopping the ash unloading and achieving quantitative collection and packaging of the incineration ash.

[0103] The lifting mechanism 80 is located at the bottom of the second sealed chamber 20. The inspection port 203 on the second sealed chamber 20 can be set on the lower end of the side wall of the second sealed chamber 20 to facilitate the maintenance of the lifting mechanism 80 and other components.

[0104] Furthermore, to prevent the leakage of air containing radioactive material from the first sealed chamber 10 and the second sealed chamber 20, the radioactive incineration ash collection and packaging system of the present invention also includes an air inlet device connected to the first sealed chamber 10 and an exhaust device connected to the second sealed chamber 20. The exhaust device and the air inlet device work together to ensure that the air inlet volume is less than the air outlet volume, thereby creating a negative pressure in the second sealed chamber 20, or the connected second sealed chamber 20 and the first sealed chamber 10.

[0105] The air intake device may include an air intake filter 90 and an air intake valve 901. The air intake filter 90 is connected to the air intake port opened on the first sealed chamber 10 through the air intake valve 901 to filter the air entering the first sealed chamber 10.

[0106] The exhaust system includes an exhaust fan 91, an exhaust filter 92 connected to the inlet side of the exhaust fan 91, and an exhaust duct 93 connected between the exhaust filter 92 and the second sealed chamber 20. When the exhaust fan 91 operates, it draws air out of the second sealed chamber 20. The drawn air is filtered by the exhaust filter 92 and then transported to the corresponding treatment system by the exhaust fan 91. An exhaust valve 94 is provided on the exhaust duct 93. Alternatively, the exhaust duct 93 can be replaced by an exhaust valve 94, which connects the exhaust filter 92 and the second sealed chamber 20 and has both on / off functions.

[0107] A first differential pressure gauge 104 is provided on the first sealed chamber 10, and a second differential pressure gauge 204 is provided on the second sealed chamber 20. The first differential pressure gauge 104 and the second differential pressure gauge 204 are used to monitor the internal pressure of the first sealed chamber 10 and the second sealed chamber 20, respectively.

[0108] The method for collecting and packaging radioactive incineration ash using the above-mentioned radioactive incineration ash collection and packaging system may include the following steps:

[0109] S1. Place the metal ash bucket 200 on the first roller conveyor 31, open the first sealing door 11, and transport the metal ash bucket 200 into the first sealing chamber 10 through the first roller conveyor 31, the opened first sealing door 11, and the second roller conveyor 32.

[0110] When the metal ash bucket 200 reaches the lid pick-up and drop-off station, the first limiting mechanism 71 is triggered, the first roller conveyor 31 and the second roller conveyor 32 stop rotating; the first sealing door 11 closes.

[0111] S2. Inside the first sealed chamber 10, the lid-removing mechanism 40 removes the lid from the metal ash bucket 200.

[0112] Specifically, the lid-removing mechanism 40 is activated, the electromagnet 42 of the lid-removing mechanism 40 descends, and is energized to pick up the lid 210 on the metal ash bucket 200. After the electromagnet 42 rises, it takes the lid 210 away from the metal ash bucket 200, thereby opening the metal ash bucket 200.

[0113] S3. The second sealing door 12 opens, and the metal ash bucket 200 is conveyed into the second sealing chamber 20 through the second roller conveyor 32 and the third roller conveyor 33. When the metal ash bucket 200 reaches the unloading and packaging station, the third limiting mechanism 73 is triggered, and the second roller conveyor 32 and the third roller conveyor 33 stop rotating; the second sealing door 12 closes.

[0114] In this process, after the metal ash bucket 200 arrives at the unloading and packaging station, the lifting mechanism 80 below the third roller conveyor 33 is activated to lift the metal ash bucket 200 and weigh it using a weighing sensor to obtain the net weight of the metal ash bucket 200.

[0115] S4. Start the packaging device to heat-seal the packaging film into a film bag 300 and place it into the metal ash bucket 200.

[0116] The specific forming method of the packaging film can be referred to the relevant description in the above-mentioned radioactive incineration ash collection and packaging system, and will not be repeated here.

[0117] S5. The incineration ash is discharged into the membrane bag 300 through the feeding pipe 50. After the membrane bag 300 is filled with the predetermined weight of incineration ash, the packaging device seals the membrane bag 300.

[0118] The standard for completion is as follows: the weight of the metal ash bucket 200 (containing incineration ash), as measured by the weighing sensor on the lifting mechanism 80, reaches a predetermined weight. After the incineration ash is filled into the membrane bag 300 formed inside the metal ash bucket 200, the discharge pipe 50 stops discharging ash. The horizontal sealing mechanism 65 of the packaging device seals the membrane bag 300 and then cuts it.

[0119] S6. After the metal ash bucket 200 is filled with ash, the second sealing door 12 is opened, and the third roller conveyor 33 and the second roller conveyor 32 are reversed to send the filled metal ash bucket 200 back to the first sealing chamber 10.

[0120] In step S6, after the metal ash bucket 200 is filled with ash, the lifting mechanism 80 resets, lowering the metal ash bucket 200 back to its original position. After resetting, the metal ash bucket 200 containing incineration ash is then reversed and sent back to the first sealed chamber 10 via the third roller conveyor 33 and the second roller conveyor 32.

[0121] S7. After the metal ash bucket 200 reaches the lid-taking and placement station of the first sealed chamber 10, the second sealed door 12 closes, and the lid-taking and placement mechanism 40 puts the lid 210 on the metal ash bucket 200.

[0122] Specifically, when the metal ash bin 200 reaches the lid-picking / placing station, the second limiting mechanism 72 is triggered, stopping the rotation of the second roller conveyor 32 and the third roller conveyor 33; the second sealing door 12 closes. The lid-picking / placing mechanism 40 is activated, and the electromagnet 42 of the lid-picking / placing mechanism 40 descends, placing the lid 210 it has picked up onto the metal ash bin 200. After the electromagnet 42 is de-energized, it disengages from the lid 210 and rises back to its original position. The metal ash bin 200 is sealed by the lid 210, enclosing the bagged incineration ash inside the metal ash bin 200.

[0123] S8. After the lid 210 of the metal ash bucket 200 is closed, the first sealing door 11 is opened, and the metal ash bucket 200 is sent out of the first sealing chamber 10 through the second roller conveyor 32 and the first roller conveyor 31.

[0124] The incineration ash that exits the first sealed chamber 10 is packaged into bags using membrane bags 300, making it less prone to leakage. Subsequent transfer, temporary storage, and processing of the bagged incineration ash can be carried out using metal ash containers 200, which can be reused, thus achieving bagged packaging of the incineration ash.

[0125] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
