Description

Technical Field

[0001] The invention belongs to the technical field of radioactive waste treatment, and particularly relates to a radioactive filter waste filter element frame separation device and method. Background Art

[0002] Radioactive waste filters are a common and large - quantity - generated type of radioactive waste. These filters are widely used in radioactive air purification systems and play an important role in removing radioactive aerosols and particulate pollutants in the air, which is crucial for ensuring the air quality in nuclear facilities and the health and safety of staff. In traditional treatment methods, the separation of the filter element and the frame mainly relies on manual operation. Operators need to disassemble the filter element and the frame with simple tools under strict radiation protection conditions. This process not only consumes a large amount of manpower and time, but also, due to the uncertainty of manual operation, is extremely likely to cause damage to the filter element, thus increasing the risk of radioactive material leakage. In addition, materials such as glass fibers in the filter element are easily scattered into the air during the separation process. Once inhaled by operators, it will cause serious harm to the human respiratory system. From the perspective of resource utilization, the metal frame of the filter usually has a high recycling value. If the filter element and the frame can be effectively separated, the metal frame can be reused after cleaning and release from regulatory control, which can not only reduce the manufacturing cost of new equipment, but also reduce resource waste. Currently, due to the lack of efficient separation technology and equipment, a large number of metal frames can only be treated as radioactive waste together with the filter element, which is undoubtedly a great waste of resources.

[0003] In the prior art, when disassembling the plate - type filter element of the filter, due to the structural design of the filter where the filter element and the frame are tightly bonded by sealant. Although this design can effectively ensure the filtering performance and sealing of the filter, it brings great difficulties in separating the filter element and the frame in the later stage. When the existing equipment disassembles, some filter element debris will adhere to the frame, resulting in incomplete disassembly and residues, affecting the subsequent reuse of the frame.

The connecting column 84 slides inside the sliding groove 33, and at the same time drives the lifting plate 34, the conductive rod 36 and the pressing rod 35 to descend, so that the three rods can be aligned with the jacks 51 on the outer wall of the gripper 50 for the next step of operation.

[0045] Please refer to Figure 1 and Figure 2 , a moving frame 11 is slidably installed on the outer wall of the conveying frame 1. A connecting rod 13 is installed on the outer wall of the moving frame 11. One end of the connecting rod 13 is installed with a sliding plate 12, and the transportation assembly 5 is installed on the outer wall of the sliding plate 12. The sliding plate 12 slides on the top of the conveying frame 1. A reducer 15 is installed on the outer wall of the moving frame 11, and a driving motor 14 is installed on the outer wall of the reducer 15. A connecting shaft 4 is installed on the outer wall of the moving frame 11, a second gear 41 is installed on the outer wall of the connecting shaft 4, and two rack bars 42 are installed at the bottom of the conveying frame 1. The second gear 41 meshes with the rack bars 42, and a plurality of conveying rollers 43 are installed on the top of the conveying frame 1.

[0046] Specifically, the driving motor 14 drives the reducer 15 to work. The reducer 15 drives the connecting shaft 4 and the second gear 41 to rotate. The second gear 41 meshes with the rack bars 42, so as to drive the sliding plate 12 to slide on the conveying rollers 43 through gear meshing to achieve the moving function.

[0047] Please refer to Figure 1, a second frame 21 is installed on the back of the conveying frame 1. Connectors 22 are installed on the outer walls of the second frame 21 and the first frame 2.

[0048] Specifically, when the filter element and the frame are separated, at this time the frame rises along the lifting plate 81 and then enters onto the second frame 21. The removed filter element enters into the interior of the first frame 2. At this time, the second motor 23 is started. The second motor 23 drives a plurality of conveying shafts 27 on the first frame 2 and the second frame 21 to rotate through the chain 25, the first gear 24 and the driven gear 26, thereby respectively transporting the filter element and the frame.

[0049] Please refer to Figure 1 , Figure 5 and Figure 6 , the transportation assembly 5 includes a gripper 50 installed on the outer wall of the sliding plate 12. Three jacks 51 are opened on the back of the gripper 50. A limiting ring 54 is installed on the inner bottom wall of the gripper 50. An adjusting plate 52 is slidably installed on the inner wall of the limiting ring 54. An impact plate 53 is installed at one end of the adjusting plate 52. A triangular convex block 55 is installed on the top of the adjusting plate 52. A return spring 56 is installed on the inner wall of the gripper 50. A distribution box 57 is installed on the inner bottom wall of the gripper 50.

A clamping block 59 is installed through the top of the gripper 50. A first spring 510 is installed around the outer wall of the clamping block 59.

[0050] Specifically, place the filter element of the filter to be disassembled on the gripper 50. Then the gripper 50 moves along with the sliding plate 12 and enters into the processing groove 8. At this time, the extrusion rod 35 and the conductive rod 36 are respectively inserted into the jacks 51. At this time, the extrusion rod 35 extrudes the impact plate 53, and the impact plate 53 drives the adjusting plate 52 to move. The adjusting plate 52 extrudes the return spring 56. During this process, when the adjusting plate 52 drives the convex block 55 to move, it extrudes the clamping block 59. The clamping block 59 rises to drive the first spring 510 to expand and contract, so that a plurality of convex blocks 55 clamp and limit the filter element to prevent the filter element from shifting during the processing.

[0051] It should be noted that the conductive rod 36 supplies power to the heating wire 58 through the distribution box 57, enabling the gripper 50 to heat the filter element, thereby heating the sealant between the filter element and the frame, softening the sealant, and facilitating subsequent separation.

[0052] Please refer to Figure 7 and Figure 9 , a first chamber 6 is installed on the inner top wall of the fixed box 30. A first water pump 61 is installed at the bottom of the first chamber 6. The input end of the first water pump 61 is installed with a water inlet pipe, and one end of the water inlet pipe extends into the interior of the first chamber 6. The output end of the first water pump 61 is installed with a telescopic pipe 62. One end of the telescopic pipe 62 is installed with a first spraying pipe 66. A fixing frame 63 is installed on the inner wall of the fixed box 30. A support plate 64 is installed on the outer wall of the fixing frame 63. A third motor 65 is installed on the top of the support plate 64.

[0053] Specifically, when the gripper 50 drives the filter element into the interior of the processing tank 8, at this time, the first water pump 61 works, pumping out the remover in the first chamber 6, and conveying it to the interior of the first spraying pipe 66 through the telescopic pipe 62. Subsequently, the third motor 65 works. The third motor 65 uses a servo motor, first rotates forward and then reverses. The third motor 65 drives the first spraying pipe 66 to swing reciprocally, thereby evenly spraying the remover onto the joint of the filter element and the frame for easy glue removal.

[0054] Please refer to Figure 7 , Figure 8 and Figure 9 , the output end of the third motor 65 extends into the interior of the fixing frame 63, and the output end of the third motor 65 is connected to the outer wall of the first spraying pipe 66. A disassembly rod 68 is installed through the top of the support plate 64. A second spring 69 is installed around the outer wall of the disassembly rod 68. A trigger plate 610 is installed at the top of the disassembly rod 68. A cam 67 is installed at the output end of the third motor 65. A lower pressing plate 611 is installed at the bottom of the disassembly rod 68. A second chamber 7 is installed on the outer wall of the first chamber 6. The first chamber 6 is filled with remover. The second chamber 7 is filled with a mixture of deionized water and abrasive. A second water pump 71 is installed at the bottom of the second chamber 7. The input end of the second water pump 71 is installed with a water inlet pipe, and one end of the water inlet pipe extends into the interior of the second chamber 7. A regulator 72 is installed on the inner wall of the fixed box 30. A fourth motor 73 is installed on the outer wall of the regulator 72. The output end of the fourth motor 73 extends into the interior of the regulator 72. A reciprocating lead screw 74 is installed at the output end of the fourth motor 73.

A high-pressure water pump 76 is installed on the outer wall of the moving block 75, and the high-pressure water pump 76 is communicated with the output end of the second water pump 71.

[0055] Specifically, after the filter element is sprayed with the glue remover, the cam 67 then squeezes the trigger plate 610, causing the disassembly rod 68 to drive the lower pressing plate 611 to squeeze the filter element, so that the filter element is separated from the frame. Then the filter element continues to move forward, and the second water pump 71 operates to spray deionized water and abrasive through the high-pressure water pump 76 to form a water jet to cut the filter element, so that the filter element and the frame are completely separated. The regulator 72 can drive the moving block 75 and the high-pressure water pump 76 to adjust the position through the fourth motor 73 and the reciprocating lead screw 74 to facilitate the cutting function;

[0056] It should be noted that the wastewater after cutting flows downward into the purification tank 9. At the same time, the air extraction pump 10 continuously operates to transport the dust and pollutants generated by cutting into the purification tank 9 to prevent the pollution from spreading outward.

[0057] A method for separating a radioactive waste filter element from its frame. The separation method of the separation device is as follows;

[0058] S1. Place the radioactive waste filter element to be disassembled on the gripper 50 of the transportation component 5, fix the filter element through the clamping block 59 and the first spring 510 to ensure its stability. Start the driving motor 14, drive the moving frame 11 and the sliding plate 12 to move along the conveying frame 1 through the speed reducer 15, and transport the filter element to the processing groove 8 of the cutting component 3;

[0059] S2. Start the first water pump 61 below the first chamber 6, and evenly spray the glue remover to the bonding part of the filter element and the frame through the telescopic tube 62 and the first spraying tube 66 to soften the sealant. The third motor 65 drives the cam 67 to rotate, driving the disassembly rod 68 and the lower pressing plate 611 to periodically press down to enhance the penetration effect of the glue remover;

[0060] S3. Start the second water pump 71 and the high-pressure water pump 76 in the second chamber 7, and spray the mixture of deionized water and abrasive to the separation area to remove the residual debris;

[0061] S4. After the filter element and the frame are separated, the frame rises along the lifting plate 81, and then the frame is output outward through the second frame 21. The disassembled filter element is output outward through the first frame 2 to realize the function of separate storage;

[0062] S5. The air extraction pump 10 operates throughout the process to inhale the radioactive aerosols and dust generated during cutting and cleaning into the purification tank 9, neutralize the harmful substances through the purification liquid, and collect the separated filter element debris centrally and package and dispose of it according to the radioactive waste treatment standard.

[0063] The following are the specific implementation cases of the present invention;

[0064] Case 1: Treatment of the filter element of the radioactive air filtration system in a nuclear power plant

[0065] Application scenarios:

[0066] The ventilation system of nuclear power plants needs to regularly replace radioactive air filters. These filters accumulate highly radioactive aerosols due to long-term use and need to be safely disassembled to recover the metal frame and encapsulate the filter element debris.

[0067] Equipment applications:

[0068] The transportation component clamps and conveys the filter element to be processed to the processing tank of the cutting component. The glue remover spraying (step S2) softens the sealant between the filter element and the frame, and the penetration effect is enhanced by the disassembly rod with periodic downward pressure. High-pressure water abrasive cleaning (step S3) removes the residual debris to ensure that there is no radioactive substance residue on the surface of the frame. The air extraction pump and the purification box adsorb radioactive dust and aerosols throughout the process to avoid polluting the operating environment. The separated metal frame is output through the second rack, reused after decontamination detection; the filter element debris is disposed of by standard encapsulation.

[0069] Case 2: Batch filter disassembly in nuclear waste treatment plants

[0070] Application scenarios:

[0071] Nuclear waste treatment plants need to process a large number of radioactive waste filters, and traditional manual disassembly has low efficiency and high risks.

[0072] Equipment applications:

[0073] The conveying rack and the moving rack work together to achieve continuous feeding and transportation of the filter element (step S1), improving the processing efficiency.

[0074] Multi-station linkage: The gear chain system of the connector drives the conveying shaft to achieve synchronous sorting and output of the frame and the filter element (step S4). Automatic cleaning and purification: The deionized water mixed with abrasives in the second chamber can batch remove debris, and the purification box processes radioactive pollutants in real time. The equipment supports 24-hour operation, significantly reducing the risk of manual exposure to radiation and improving the recovery rate of metal frames at the same time.

[0075] Case 3: Safe handling of radioactive filters in nuclear medicine laboratories

[0076] Application scenarios:

[0077] After using radioactive isotopes in nuclear medicine laboratories, the small filters supporting the experimental equipment need to be safely disassembled to prevent the spread of radioactive substances.

[0078] Equipment applications:

[0079] Adjustable Design of the Clamp: The electric heating wire (58) and the clamping block (59) are used to adapt to small filter elements of different sizes, ensuring stable fixation. Precise Glue Dissolution and Cleaning: Aiming at the small bonding area of laboratory filter elements, the glue dissolvent spraying in the first chamber and the high-pressure water pump (Steps S2 - S3) achieve refined separation. Compact Purification System: The miniaturized design of the air extraction pump and the purification box is adapted to the laboratory space, effectively controlling the diffusion of radioactive aerosol. The separated filter element debris is directly encapsulated, and the metal frame can be used in other low-risk scenarios after being decontrolled.
