Description

Technical Field

[0001] This disclosure relates to the technical field of nuclear engineering, and more particularly to a filter cartridge separation device and a radioactive nuclear power filter cartridge separation system. Background Technology

[0002] Filters are crucial components of the primary water filtration system in nuclear power plant reactors, playing a vital role in filtering and purifying the primary water. When the filtration efficiency no longer meets system requirements, the filters need to be replaced, and the old filters are disposed of as radioactive solid waste. To implement the minimization management of radioactive solid waste and alleviate the pressure of radioactive waste storage in nuclear power plants, it is necessary to conduct timely research on volume reduction technologies for various types of radioactive solid waste. When reducing the volume of wastewater filters, the filter dose rate is high, so direct compression and volume reduction are not feasible; the dose rate of the decommissioned filter must be reduced. The glass fiber filter media in the filter element contributes the most to the filter dose rate, therefore, the filter media needs to be separated to meet the requirements of compression and volume reduction. Because the filter element is a welded seal, and the radiation dose rate of the decommissioned filter element is high, the disassembly of the filter is difficult to perform, and currently, there is no equipment specifically designed for this task.

[0003] Therefore, it is necessary to propose a filter cartridge separation device and a radioactive nuclear power filter cartridge separation system to at least partially solve the problems existing in the prior art. Summary of the Invention

Detailed Implementation

[0066] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0067] like Figures 1 to 8 As shown, a filter element separation device 100 is provided according to a first aspect embodiment of the present disclosure, comprising: a support frame 110, wherein the support frame 110 is provided with a movable part 120; a clamping part 130 is disposed on the movable part 120, wherein the movable part 120 drives the clamping part 130 to move relative to the support frame 110, and the clamping part 130 is used to clamp the filter element; a cutting part 140 is disposed on the support frame 110, wherein the cutting part 140 separates the cover plate of the filter element, and the separation mechanism 150 separates the glass fiber of the filter element from the tube body of the filter element.

[0068] It is understood that the filter element separation device 100 provided in this embodiment includes a support portion, a clamping portion 130, a cutting portion 140, and a separation mechanism 150. A movable portion 120 is provided on the support frame 110 to support the movable portion 120. The clamping portion 130 is disposed on the movable portion 120, and the movable portion 120 can move the clamping portion 130 relative to the support frame 110, thereby clamping the filter element and moving the filter element relative to the support frame 110. The cutting portion 140 is disposed on the support frame 110, and the clamping portion 130 can move the filter element to the working position of the cutting portion 140 to cut the cover plate of the filter element. The separation mechanism 150 is mounted on the support frame 110. After the cover plate of the filter element is cut and separated by the cutting section 140, the glass fiber and the tube body of the filter element can be separated by the separation mechanism 150. This removes the glass fiber filter material that contributes the most to the dose rate, allowing the remaining parts of the filter element to be classified, stored, and compressed to reduce volume, thus alleviating the pressure of radioactive waste storage. The filter element separation device 100 adopts a detachable modular structure, with high integration and small size. It can be implemented in the limited working space of a nuclear power plant. The clamping, moving, and cutting of the filter element are all automated, requiring no human intervention, avoiding radiation risks to workers, and improving safety.

[0069] For example, such as Figure 2 and Figure 3 The diagram shows the specific structure of a Type I filter element 300. The Type I filter element 300 includes a first outer tube 310, a first inner tube 320, a first cover plate 330, a second cover plate 340, and Type I glass fiber 350. The Type I glass fiber 350 is disposed within the first inner tube 320. The first outer tube 310 is fitted inside the first inner tube 320. The first cover plate 330 is disposed at one end of the Type I filter element 300, and the second cover plate 340 is disposed at the other end. The first outer tube 310 and the first inner tube 320 are fixed together by the first cover plate 330 and the second cover plate 340, maintaining their relative positions. Figure 4 and Figure 5 The diagram shows the specific structure of a Type II filter element 400. The Type II filter element 400 includes a second outer tube 410, a second inner tube 420, a third cover plate 430, a fourth cover plate 440, and Type II glass fiber 450350. The Type II glass fiber 450350 is disposed within the second inner tube 420, the second outer tube 410 is sleeved within the second inner tube 420, the third cover plate 430 is disposed at one end of the Type II filter element 400, and the fourth cover plate 440 is disposed at the other end of the Type II filter element 400. The second outer tube 410 and the second inner tube 420 can be fixed by the third cover plate 430 and the fourth cover plate 440 to maintain their relative positions.

[0070] In some examples, such as Figure 1 As shown, the filter element separation device 100 further includes a storage box 160, which is disposed at the bottom of the support frame 110. Multiple storage boxes 160 are provided for classifying and storing the tube, the cover plate and the glass fiber.

[0071] It is understood that the filter element separation device 100 may also be provided with a storage box 160. Specifically, multiple storage boxes 160 may be provided, arranged at intervals at the bottom of the support frame 110, and each storage box corresponds to a different part of the filter element, so as to classify and store at least the tube body, cover plate and glass fiber of the filter element, so as to facilitate subsequent compression and volume reduction processing.

[0072] In some examples, such as Figure 1 and Figure 2 As shown, the moving part 120 includes: a first guide rail 121, disposed on the support frame 110; a first plate 122, slidably connected to the first guide rail 121 via a first slider; a first transmission screw 123, disposed on the support frame 110, the axial direction of the first transmission screw 123 being consistent with the guiding direction of the first guide rail 121; a first screw nut, connected to the first plate 122 and screwed onto the first transmission screw 123; and a first drive motor 124, used to drive the first transmission screw 123 to rotate.

[0073] It is understood that the moving part 120 may be provided with a first guide rail 121, a first plate 122, a first transmission screw 123, a first screw nut, and a first drive motor 124. The first guide rail 121 is disposed on the support frame 110 along its length. The first plate 122 is slidably connected to the first guide rail 121 via a first slider, allowing the first plate 122 to slide along the length of the support frame 110 and support the clamping part 130. The first transmission screw 123 is disposed on the support frame 110, and the axial direction of the first transmission screw 123 is consistent with the guiding direction of the first guide rail 121. The first screw nut is connected to the bottom of the first plate 122 and screwed onto the first transmission screw 123. The first transmission screw 123 is connected to the first drive motor 124 via a coupling, allowing the first drive motor 124 to drive the first transmission screw 123 to rotate. With this configuration, when the clamping part 130 needs to clamp the filter element, the first drive motor 124 can be activated. The power output shaft of the first drive motor 124 drives the first transmission screw 123 to rotate, thereby allowing the first screw nut to move along the axis of the first transmission screw 123. This, in turn, drives the first plate 122 and the clamping part 130 on the first plate 122 to move until the clamping part 130 clamps the filter element. Furthermore, by changing the rotation direction of the output shaft of the first drive motor 124, the moving direction of the first plate 122 can be adjusted, allowing the clamping part 130 to move the filter element to a designated position, such as the working position of the cutting part 140 or the working position of the separation mechanism 150. The movement process of the moving part 120 requires no human intervention, achieving automation, avoiding radiation risks to workers, and improving safety.

[0074] It is understood that the filter element separation device 100 may also be equipped with a controller, a first distance sensor, a second distance sensor, and a third distance sensor. The first distance sensor detects the first distance data between the clamping part 130 and the filter element. The controller can control the rotation speed and direction of the first drive motor 124 based on the detected first distance data to precisely control the movement distance of the clamping part 130. The second distance sensor detects the second distance data between the filter element and the cutting part 140. The controller can control the rotation speed and direction of the first drive motor 124 based on the detected second distance data to precisely control the movement distance of the clamping part 130, ensuring that the cutting part 140 can accurately cut the cover plates at both ends of the filter element. The third distance sensor detects the third distance data between the filter element and the separation mechanism 150. The controller can control the rotation speed and direction of the first drive motor 124 based on the detected third distance data to precisely control the movement distance of the clamping part 130, ensuring that the separation mechanism 150 can completely separate the glass fiber and the filter element.

[0075] In some examples, such as Figures 1 to 6As shown, the clamping part 130 includes: a clamping cylinder, which is respectively disposed at both ends of the first plate 122; a clamping block, which is connected to the clamping cylinder; the tube body includes an outer tube and an inner tube, the outer tube is sleeved on the inner tube, and the two ends of the outer tube are clamped by the clamping block; and a positioning mechanism, which is disposed on the clamping block, for fixing the inner tube to the outer tube.

[0076] Understandably, the clamping part 130 may be equipped with clamping cylinders, clamping blocks, and a positioning mechanism. Two clamping cylinders are provided, located at opposite ends of the first plate 122. The clamping blocks are connected to the moving pistons of the clamping cylinders, and the up-and-down stroke of the moving pistons causes the clamping blocks to clamp or release the filter element. The filter element may have an outer tube and an inner tube, with the outer tube fitted over the inner tube. The clamping blocks clamp and position the outer tube of the filter element. The positioning mechanism is located at the clamping blocks. After the clamping part 130 clamps the outer tube of the filter element and moves it to the cutting part 140, the cutting part 140 cuts off the cover plates at both ends of the filter element. The outer and inner tubes, no longer constrained by the cover plates, will move relative to each other. At this time, the positioning mechanism supports and positions the inner tube to ensure that its position relative to the outer tube remains unchanged, preventing the inner tube and glass fiber from falling into incorrect positions and affecting classified storage. The clamping part 130 operates without human intervention, exhibiting a high degree of automation.

[0077] In some examples, such as Figures 1 to 6 As shown, the positioning mechanism includes: a clamping cylinder disposed on the clamping block; and positioning claws connected to the clamping cylinder; wherein, after the cutting part 140 cuts off the cover plates at both ends of the filter element, the clamping cylinder drives the positioning claws to open and tighten the inner tube.

[0078] It is understandable that the positioning mechanism may be equipped with a clamping cylinder and positioning claws. The clamping cylinder may be located at the clamping block, and the positioning claws are connected to the clamping cylinder. After the clamping part 130 clamps the outer tube of the filter element and moves it to the cutting part 140, the cutting part 140 cuts off the cover plates at both ends of the filter element. The outer tube and inner tube, no longer constrained by the cover plates, will move relative to each other. The clamping cylinder controls the positioning claws to tighten the inner tube, allowing the inner tube to move synchronously with the clamping cylinder and the clamping block. Because the clamping block holds the outer tube, the inner tube can move synchronously with the outer tube, preventing it from falling off.

[0079] For example, the clamping part 130 may be provided with a first clamping cylinder 131, a first clamping block 132, a first pressing cylinder 133, and a first positioning claw for use when processing type I filter element 300; and the clamping part 130 may also be provided with a second clamping cylinder 134, a second clamping block 135, a second pressing cylinder 136, and a second positioning claw for use when processing type II filter element 400, wherein the first clamping cylinder 131 is located outside the second clamping cylinder 134. This arrangement can improve the applicability of the filter element separation device 100. When in use, the filter element type can be determined. If the filter element is determined to be a Type I filter element 300, the first clamping cylinder 131 is activated, causing the first clamping block 132 to clamp both ends of the outer tube of the Type I filter element 300. After the Type I filter element 300 is moved to the cutting section 140 to remove the end caps, the first pressing cylinder 133 is activated, and the inner tube is tightened by the first positioning claw, so that the inner and outer tubes of the Type I filter element 300 can move synchronously. If the filter element is determined to be a Type II filter element 400, the second clamping cylinder 134 is activated, causing the second clamping block 135 to clamp both ends of the outer tube of the Type II filter element 400. After the Type II filter element 400 is moved to the cutting section 140 to remove the end caps, the second pressing cylinder 136 is activated, and the inner tube is tightened by the second positioning claw, so that the inner and outer tubes of the Type II filter element 400 can move synchronously.

[0080] In some examples, such as Figures 1 to 7 As shown, the cutting part 140 includes: a first mounting plate 141 disposed on the side of the support frame 110; a lifting mechanism 142 disposed on the first mounting plate 141; and a cutting mechanism 143 connected to the lifting mechanism 142, which drives the cutting mechanism 143 to move closer to or further away from the clamping mechanism.

[0081] It is understood that the cutting section 140 may be provided with a first mounting plate 141, a lifting mechanism 142, and a cutting mechanism 143. The first mounting plate 141 may be provided on the side of the support frame 110 to support the lifting mechanism 142. The lifting mechanism 142 is vertically disposed on the first mounting plate 141. The cutting mechanism 143 is connected to the lifting mechanism 142, so that the lifting mechanism 142 can drive the cutting mechanism 143 to move towards or away from the clamping mechanism. With this configuration, the moving part 120 moves the clamping part 130, causing the cover plate at one end of the filter element to move to the working position of the cutting part 140. Then, the lifting mechanism 142 moves the cutting mechanism 143 downward to cut the cover plate at one end of the filter element. After cutting, the lifting mechanism 142 moves the cutting mechanism 143 upward to the top of the filter element. The moving part 120 then moves the clamping part 130 again, causing the cover plate at the other end of the filter element to move to the working position of the cutting part 140. Again, the lifting mechanism 142 moves the cutting mechanism 143 downward to cut the cover plate at the other end of the filter element. After cutting, the lifting mechanism 142 moves the cutting mechanism 143 upward to the top of the filter element. The moving part 120 then moves the clamping part 130, causing the filter element to fall out of the working range of the cutting part 140. Through the cooperation of the moving part 120 and the cutting part 140, automated cutting of the filter element cover plate is achieved without human intervention, avoiding radiation exposure to workers and improving safety.

[0082] In some examples, such as Figures 1 to 7 As shown, the lifting mechanism 142 includes: a second plate 1421, vertically connected to the first mounting plate 141; a second guide rail 1422, disposed on the second plate 1421 along its extension direction; a connecting plate 1423, to which the cutting mechanism 143 is connected, and which is slidably connected to the second guide rail 1422 via a second slider 1425; a second transmission screw 1424, disposed on the second plate 1421, the axial direction of which is consistent with the guiding direction of the second guide rail 1422; a second screw nut, connected to the connecting plate 1423 and screwed onto the second transmission screw 1424; and a second drive motor 1426 for driving the second transmission screw 1424 to rotate.

[0083] It is understood that the lifting mechanism 142 may include a second plate 1421, a second guide rail 1422, a connecting plate 1423, a second transmission screw 1424, a second screw nut, and a second drive motor 1426. The second plate 1421 is vertically connected to the first mounting plate 141, and the second guide rail 1422 is mounted on the second plate 1421 along its height. The connecting plate 1423 is slidably connected to the second guide rail 1422 via a second slider 1425, allowing the connecting plate 1423 to slide along the height of the second plate 1421. The cutting mechanism 143 is connected to the connecting plate 1423, allowing the cutting mechanism 143 to slide synchronously with the connecting plate 1423. The second transmission screw 1424 is mounted on the second plate 1421, and the axial direction of the second transmission screw 1424 is consistent with the guiding direction of the second guide rail 1422. The second lead screw nut is connected to the connecting plate 1423 and screwed onto the second transmission lead screw 1424. The second transmission lead screw 1424 can be connected to the second drive motor 1426 via a coupling, so that the second drive motor 1426 can drive the second transmission lead screw 1424 to rotate. With this configuration, when the cutting mechanism 143 is cutting the cover plate, the second drive motor 1426 can be started. The power output shaft of the second drive motor 1426 drives the second transmission lead screw 1424 to rotate, thereby allowing the second lead screw nut to move along the axis of the second transmission lead screw 1424. In turn, the second lead screw nut drives the connecting plate 1423 and the cutting mechanism 143 on the connecting plate 1423 to move until the cutting mechanism 143 separates the cover plate and the filter element. The direction of movement of the connecting plate 1423 can be adjusted by changing the rotation direction of the output shaft of the second drive motor 1426, so that the cutting mechanism 143 can move away from the area where the filter element is located to complete the cutting. The cutting process of the cutting unit 140 does not require human intervention, realizing automation, avoiding radiation risks to workers, and improving safety.

[0084] In some examples, such as Figures 1 to 7 As shown, the cutting mechanism 143 includes: a third plate 1431 connected to the connecting plate 1423; a third drive motor 1432 disposed on the third plate 1431; a transmission shaft rotatably disposed on the third plate 1431, one end of the transmission shaft being connected to the output shaft of the third drive motor 1432; a wheel connected to the other end of the transmission shaft; and a band saw 1437 connected to the wheel.

[0085] Understandably, the cutting mechanism 143 may include a third plate 1431, a third drive motor 1432, a transmission shaft, a wheel, and a band saw 1437. The third plate 1431 is connected to the connecting plate 1423 and may be parallel to the first mounting plate 141. The third drive motor 1432 may be located at the top of the third plate 1431. The transmission shaft is connected to the output shaft of the third drive motor 1432 so that the transmission shaft can rotate synchronously with the output shaft of the third drive motor 1432. The wheel is located at the other end of the transmission shaft and can rotate synchronously with the transmission shaft. The band saw 1437 may be connected to the wheel, thereby driving the band saw 1437 to rotate to cut the cover plate.

[0086] It should be noted that the drive shaft may be equipped with a drive shaft 1433 and a driven shaft 1434, and the wheel body may be equipped with a drive wheel 1435 and a driven wheel 1436. The drive shaft 1433 is connected to the output shaft of the third drive motor 1432, and the drive wheel 1435 and drive shaft 1433 rotate synchronously. One end of the band saw 1437 is fitted onto the drive wheel 1435, and the other end of the band saw 1437 is fitted onto the driven wheel 1436. The driven shaft 1434 can rotate relative to the third plate 1431, and the driven wheel 1436 can drive the driven shaft 1434 to rotate.

[0087] In some examples, such as Figures 1 to 8 As shown, the separation mechanism 150 includes: a guide post 1511 and a cylinder 151, which are disposed on the support frame 110; a second mounting plate 152, which is connected to the guide post 1511 and the cylinder 151; and a push rod, which is disposed on the second mounting plate 152, and the axial direction of the push rod is consistent with the guiding direction of the first guide rail 121. After the cutting part 140 cuts off the cover plates at both ends of the filter element, the guide post 1511 and the cylinder 151 drive the push rod to move so that the position of the push rod and the glass fiber are aligned. The clamping part 130 drives the filter element to move until the push rod pushes the glass fiber out of the filter element.

[0088] It is understood that the separation mechanism 150 may include a guide post 1511, a cylinder 151, a second mounting plate 152, and a push rod. The guide post 1511, or cylinder 151, may be located on the side of the support frame 110, and the guide post 1511, cylinder 151, and the clamping part 130 in its initial position are located at opposite ends of the support frame 110. The second mounting plate 152 may be connected to the guide post 1511 of the guide post 1511, allowing the second mounting plate 152 to move along the width direction of the support frame 110. The push rod may be connected to the second mounting plate 152, and the push rod faces the clamping part 130. The axial direction of the push rod is consistent with the guiding direction of the first guide rail 121. With this configuration, after the cutting section 140 removes the cover plates at both ends of the filter element, the second mounting plate 152 can be moved by the cylinder 151 of the guide post 1511, thereby causing the position of the push rod and the glass fiber to correspond. Then, the clamping section 130 drives the filter element to move along the length of the support frame 110 towards the cylinder 151 of the guide post 1511, so that the push rod pushes the glass fiber out of the inner tube of the filter element, thereby removing the glass fiber filter material that contributes the most to the dose rate, so that the remaining part of the filter element can be classified, stored and compressed to reduce its volume, thus relieving the pressure of radioactive waste storage.

[0089] For example, the push rod may be provided with a first push rod 153 and a second push rod 154, wherein the length and position of the first push rod 153 correspond to the glass fiber of the type I filter element 300; and the length and position of the second push rod 154 correspond to the glass fiber of the type II filter element 400.
