Description

Technical Field

[0001] This invention specifically relates to a high-level radioactive solid waste overpressure head structure, method, and waste treatment equipment. Background Technology

[0002] In the radioactive solid waste treatment process, high-level radioactive solid waste generally requires compression using an overcompressor. Because the waste is radioactive, the pressure head of the high-level radioactive solid waste overcompressor is located in a hot chamber to process the waste. The pressure head needs to be replaced after long-term operation or when stress pitting or wear occurs. However, the pressure head is contaminated by direct contact with radioactive waste during operation, making it impossible for maintenance personnel to directly enter the hot chamber for replacement. If manual replacement is necessary, decontamination may be required, significantly reducing production efficiency. Existing technology uses a threaded connection between the pressure rod and the pressure head; however, this connection method may loosen due to the pressure head rotating under load during long-term operation, resulting in insufficient connection stability. Summary of the Invention

[0003] The technical problem to be solved by this invention is to address the aforementioned shortcomings in the prior art by providing a pressure head structure for a high-level radioactive solid waste overpressure press. This pressure head structure is rationally designed, enabling long-distance replacement, and the disassembly and replacement operation is simple. This invention also provides a method for replacing the pressure head structure of a high-level radioactive solid waste overpressure press, as well as waste treatment equipment.

[0004] This invention provides a pressure head structure for a high-level radioactive solid waste overcompressor, which penetrates a shielding plate and includes a pressure head, a pressure rod, a connecting rod, and an operating mechanism. The pressure rod has an axial through hole inside, and the connecting rod passes through the through hole of the pressure rod. The tail section of the connecting rod located inside the shielding plate has a T-shaped head, and the first section of the connecting rod located outside the shielding plate is connected to the operating mechanism. The pressure head has a T-shaped slot, the opening of which is rectangular, with a length greater than the wings of the T-shaped head and a width smaller than the wings. The inside of the slot is a bottom that allows the wings of the T-shaped head to rotate. The operating mechanism enables the connecting rod to rotate the T-shaped head to adjust the relative angle between the wings and the slot, so that the T-shaped head can enter or exit the T-shaped slot. It also enables the connecting rod to move the T-shaped head axially, so that the T-shaped head pulls the pressure head to the pressure rod or pushes the pressure head away from the pressure rod.

[0005] Furthermore, the operating mechanism includes a rotary table and a lifting sleeve. The rotary table is rotatably connected to one end of the pressure rod located outside the shielding plate. The rotary table has an axial through hole inside. The first section of the connecting rod is set in the through hole of the rotary table and is fixed relative to the rotary table in the axial rotation direction to achieve synchronous rotation with the rotary table. The lifting sleeve is axially movably connected in the through hole of the rotary table. The end of the first section of the connecting rod is axially fixed relative to the lifting sleeve to achieve synchronous axial movement with the lifting sleeve.

[0006] Furthermore, the section of the through hole of the rotary table facing the inner side of the shielding plate is a special-shaped hole section, and the shaft section of the first section of the connecting rod, excluding the end, is a special-shaped shaft section with the same cross-section as the special-shaped hole section. The special-shaped shaft section passes through the special-shaped hole section, so that while it can move axially relative to the rotary table, it can also be limited in the rotation direction around the axial direction by the special-shaped hole section, thus achieving synchronous rotation with the rotary table.

[0007] Furthermore, the section of the through hole of the rotary table facing the outside of the shielding plate is a threaded hole section, and the outer surface of the lifting sleeve is provided with external threads. The lifting sleeve passes into the through hole of the rotary table and is threadedly connected to the threaded hole section to achieve axial movable connection.

[0008] Furthermore, the operating mechanism also includes a locking nut with an internal thread on its inner surface. The end of the first section of the connecting rod is a threaded shaft section with an external thread. The lifting sleeve has a stepped hole inside. The locking nut is placed in the large-diameter hole section facing the outside of the shielding plate and is axially limited by the stepped face of the stepped hole. The threaded shaft section extends into the stepped hole of the lifting sleeve and is threadedly connected to the locking nut. Thus, while being able to rotate relative to the lifting sleeve, the locking nut limits the axial movement of the lifting sleeve, achieving synchronous axial movement with the lifting sleeve.

[0009] Furthermore, the operating mechanism also includes a base and a bearing. The through hole of the pressure rod has a countersunk hole at the end facing the outside of the shielding plate. The base has a cylindrical structure, is embedded in the countersunk hole, and is sleeved on the outside of the rotary table. The inner surface of the base and the outer surface of the rotary table are rotatably connected by a bearing.

[0010] Furthermore, the base is provided with multiple bearing seats, each bearing seat is evenly distributed around the axial direction of the pressure rod, and a hinge bolt is connected to the bearing seat by a pin. The hinge bolt can rotate around the pin in the bearing seat, and the end of the hinge bolt passes through the rotary table and is fastened by a nut.

[0011] Furthermore, the through hole of the pressure rod has a frustum-shaped countersunk hole at the end facing the inner side of the shielding plate, and the surface of the pressure head facing the pressure rod has a frustum-shaped boss. When the T-head pulls the pressure head tight onto the pressure rod, the boss is embedded in the frustum-shaped countersunk hole.

[0012] Furthermore, guide sleeves are fitted inside both ends of the through hole of the pressure rod to support and guide the connecting rod.

[0013] This invention also provides a method for replacing the pressure head structure of a high-level radioactive solid waste overcompressor, wherein the pressure head structure of the high-level radioactive solid waste overcompressor adopts the above-mentioned high-level radioactive solid waste overcompressor pressure head structure, and the method includes a disassembly step and an installation step.

[0014] The disassembly steps include:

[0015] The control mechanism moves the connecting rod axially, causing the T-head to stop tightening the pressure head;

[0016] The connecting rod rotates, causing the T-head's double wings to align with the slot angle.

[0017] The pressure rod, operating mechanism, and connecting rod move axially, driving the T-head to push the pressure head until the pressure head separates from the pressure rod.

[0018] The installation steps include:

[0019] The control mechanism rotates the connecting rod, causing the T-head wings to align with the slot angle.

[0020] Move the connecting rod axially to drive the T-head into the T-slot, then rotate the connecting rod to make the T-head's wings offset from the slot opening.

[0021] The connecting rod moves axially, causing the T-head to tighten the pressure head until the pressure head and the pressure rod are fully in contact.

[0022] The present invention also provides a waste treatment device, including an overcompressor, a hot chamber, and an anvil. The anvil is disposed inside the hot chamber. The overcompressor includes a pressure head structure, which is the pressure head structure of the above-mentioned high-electroactive solid waste overcompressor. The pressure head structure penetrates the shielding plate of the hot chamber and works with the anvil to complete the compression of waste.

[0023] The pressure head structure of the high-level radioactive solid waste overcompressor of the present invention has an axial through hole inside the pressure rod, a connecting rod passing through the through hole of the pressure rod, a T-shaped head on the tail section of the connecting rod located inside the shielding plate, and an operating mechanism connected to the first section of the connecting rod located outside the shielding plate. The pressure head is provided with a T-shaped slot for movable connection with the T-shaped head.

[0024] The T-head and T-slot connection will not loosen due to the force applied by the pressure head, and the operation is simple and reliable, requiring only rotation and axial movement. Furthermore, the two wings of the T-head can further tighten the pressure head, not only achieving a close fit between the pressure head and the pressure rod, but also ensuring that the two are tightly pressed together.

[0025] The connecting rod, as a transmission rod for disassembly and installation, can transmit the operating actions of the outer operating mechanism of the shielding plate to the T-head on the inner side of the shielding plate, realizing the rotation and axial movement of the T-head. Thus, the inner pressure head can be detached and installed through the operation on the outer side. Therefore, even if the pressure head is contaminated during the handling of radioactive waste, it can be replaced and maintained in a timely manner without the need for personnel to enter the radioactive environment. This not only increases efficiency but also effectively ensures personnel safety. Attached Figure Description

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, the high-level radioactive solid waste overcompressor head structure of this embodiment is configured to penetrate the shielding plate 5 and includes a pressure head 1, a pressure rod 2, a connecting rod 3, and an operating mechanism 4. The pressure rod 2 has an axial through hole inside, and the connecting rod 3 passes through the through hole of the pressure rod 2. Figure 6 As shown, the tail section of the connecting rod 3 located inside the shielding plate 5 is provided with a T-shaped head 31, and the first section of the connecting rod 3 located outside the shielding plate 5 is connected to the operating mechanism 4, as shown. Figure 4 and Figure 5 As shown, the pressure head 1 is provided with a T-shaped slot 11. The slot opening 111 of the T-shaped slot 11 is a rectangular slot, and the length of the rectangle is greater than the wings of the T-shaped head 31, while the width is smaller than the wings of the T-shaped head 31. The inside of the slot opening 111 is a slot bottom 112 that allows the wings of the T-shaped head 31 to rotate. The operating mechanism 4 can cause the connecting rod 3 to drive the T-shaped head 31 to rotate and adjust the relative angle between the wings and the slot opening 111. Figure 7 and Figure 8 As shown, this allows the T-head 31 to enter or exit the T-slot 11, and enables the connecting rod 3 to drive the T-head 31 to move axially, so that the T-head 31 can pull the pressure head 1 to the pressure rod 2 or push the pressure head 1 away from the pressure rod 2.

[0041] In this embodiment, the T-shaped head 31 and the T-shaped slot 11 are connected in a way that will not loosen due to the force applied by the pressure head 1. The operation is simple and reliable. The connection and disconnection of the two can be completed by simply rotating and moving axially. Furthermore, the two wings of the T-shaped head 31 can further tighten the pressure head 1, not only to achieve the fit between the pressure head 1 and the pressure rod 2, but also to ensure that the two can be pressed tightly together.

[0042] The connecting rod 3, as a transmission rod for disassembly and installation, can transmit the operating action of the outer operating mechanism 4 of the shielding plate 5 to the T-head 31 on the inner side of the shielding plate 5, so as to realize the rotation and axial movement of the T-head 31. Thus, the inner pressure head 1 can be detached and installed through the operation on the outer side. Therefore, even if the pressure head 1 is contaminated during the handling of radioactive waste, it can be replaced and maintained in a timely manner without the need for personnel to enter the radioactive environment. This not only increases efficiency but also effectively ensures the safety of personnel.

[0043] In this embodiment, as Figure 3 As shown, the operating mechanism 4 includes a rotary table 41 and a lifting sleeve 42. The rotary table 41 is axially connected to one end of the pressure rod 2 located outside the shielding plate 5, rotating around the connecting rod 3. The rotary table 41 has an axial through hole inside. The first section of the connecting rod 3 is positioned within the through hole of the rotary table 41 and is fixed relative to the rotary table 41 in the axial rotation direction, achieving synchronous rotation with the rotary table 41. The lifting sleeve 42 is axially movably connected to the through hole of the rotary table 41. The end of the first section of the connecting rod 3 is axially fixed relative to the lifting sleeve 42, achieving synchronous axial movement with the lifting sleeve 42. In other words, the connecting rod 3 is fixed relative to the rotary table 41 in the rotation direction, thus rotating synchronously with the rotary table 41 without affecting axial movement, while it is fixed relative to the lifting sleeve 42 in the axial direction, thus moving synchronously with the lifting sleeve 42 without affecting rotation. This configuration separates the rotation and axial movement of the connecting rod 3, avoiding interference between the two. During operation, controlling the rotation of the rotary table 41 and the axial movement of the lifting sleeve 42 respectively will enable the connecting rod 3 to drive the T-head 31 to complete the corresponding action.

[0044] In this embodiment, the section of the through hole in the rotary table 41 facing the inner side of the shielding plate 5 is a non-circular hole section 412. The shaft section of the first segment of the connecting rod 3, excluding the end, is a non-circular shaft section 33 with the same cross-section as the non-circular hole section 412. The non-circular shaft section 33 passes through the non-circular hole section 412, thereby enabling it to move axially relative to the rotary table 41 while being limited in the rotation direction around the axial direction by the non-circular hole section 412, achieving synchronous rotation with the rotary table 41. The cross-sections of the non-circular hole section 412 and the non-circular shaft section 33 can adopt shapes other than circles coaxial with the connecting rod 3, ensuring that the limitation between the cross-sections allows the non-circular hole section 412 to provide torque for driving the non-circular shaft section 33. In this embodiment, both the non-circular hole section 412 and the non-circular shaft section 33 adopt a square cross-section structure. In other embodiments, various structures such as pentagons, hexagons, and ellipses can also be adopted.

[0045] In this embodiment, the section of the through hole of the rotary table 41 facing the outside of the shielding plate 5 is a threaded section 411. The outer surface of the lifting sleeve 42 is provided with external threads. The lifting sleeve 42 passes into the through hole of the rotary table 41 and is threadedly connected to the threaded section 411 to achieve axial movable connection. The threaded connection method can realize stepless adjustment of the axial movement of the lifting sleeve 42, and can also achieve precise control of the movement length by the number of turns of the thread, which is suitable for precise control of the movement position of the T-head.

[0046] In this embodiment, the pressure head structure is vertically arranged as a whole, the lifting sleeve 42 is a sleeve structure, and a radial through hole is provided at the top flange, through which a lever can be inserted to perform rotation operation. The outer circle has threads, which mesh with the internal threads of the rotary table 41 to achieve lifting and lowering under the drive of the lever.

[0047] In this embodiment, the operating mechanism 4 also includes a locking nut 43. The inner surface of the locking nut 43 is provided with internal threads. The end of the first section of the connecting rod 3 is a threaded shaft section 32 with external threads. The lifting sleeve 42 is provided with a stepped hole. The locking nut 43 is placed in the large-diameter hole section facing the outside of the shielding plate 5, and is axially limited by the stepped surface of the stepped hole. The threaded shaft section 32 extends into the stepped hole of the lifting sleeve 42 and is threadedly connected to the locking nut 43. Thus, while being able to rotate relative to the lifting sleeve 42, the locking nut 43 is axially limited, achieving synchronous axial movement with the lifting sleeve 42. That is, when the lifting sleeve 42 rises, the stepped surface drives the locking nut 43 and the connecting rod 3 to rise together. When the lifting sleeve 42 falls, the connecting rod 3 falls due to gravity, and due to the limitation of the stepped surface, this falling is synchronized with the lifting sleeve 42. In this embodiment, the locking nut 43 is a sleeve structure with a sealed bottom and a threaded inner hole. It is connected to the end of the connecting rod 3 for fastening. The upper sealed bottom is provided with an internal hexagonal through hole, which can be used to rotate the locking nut 43 by wrench operation.

[0048] In this embodiment, the operating mechanism 4 further includes a base 44 and a bearing 45. The through hole of the pressure rod 2 has a countersunk hole at the end facing the outside of the shielding plate 5. The base 44 has a cylindrical structure and is embedded in the countersunk hole, sleeved on the outside of the rotary disk 41. The inner surface of the base 44 and the outer surface of the rotary disk 41 are rotatably connected by the bearing 45. In this embodiment, a first flange 444 is provided on the outer surface of the base 44. The first flange 444 is fixedly connected to the pressure rod 2 by fasteners. The outer ring of the bearing 45 is connected to the inner surface of the base 44, and the inner ring of the bearing 45 is connected to the outer surface of the rotary disk 41.

[0049] In this embodiment, the base 44 is provided with multiple bearing seats 441, specifically arranged on the upper end surface of the base 44. Each bearing seat 441 is evenly distributed around the axial direction of the pressure rod 2 on the upper end surface of the base 44. Specifically, four bearing seats 441 are evenly distributed around the flange surface of the first flange 444 of the base 44. A hinge bolt 443 is connected to the bearing seat 441 by a pin 442. The hinge bolt 443 can rotate around the pin 442 inside the bearing seat 441. A U-shaped groove is provided on the outer circumference of the turntable 41 at a position corresponding to the bearing seat 441 for connecting... The hinge bolt 443 passes through the rotary table 41 and is fastened by a nut. Specifically, the hinge bolt 443 is flipped upward and placed in the U-shaped groove, and the upper end of the hinge bolt 443 is tightened by the nut. Thus, after the rotary table 41 rotates to the required angle, it is fastened by the hinge bolt 443. Specifically, the outer surface of the rotary table 41 is provided with a second flange 413 located above the bearing seat 441. The flange surface of the second flange 413 is provided with four U-shaped grooves so that the hinge bolt 443 can be flipped upward to lock the rotary table 41.

[0050] In this embodiment, the through hole of the pressure rod 2 has a frustum-shaped countersunk hole at the end facing the inner side of the shielding plate 5, and the surface of the pressure head 1 facing the pressure rod 2 has a frustum-shaped boss 12. When the T-head 31 pulls the pressure head 1 onto the pressure rod 2, the boss 12 is embedded in the frustum-shaped countersunk hole. The side of the frustum-shaped structure is inclined. This inclined structure not only enables the embedded connection of the boss 12 and strengthens the connection strength between the pressure head 1 and the pressure rod 2, but also plays a guiding role, achieving an automatic alignment effect when the pressure head 1 and the pressure rod 2 are connected.

[0051] In this embodiment, the outer surface of the pressure head 1 is provided with multiple milled planes as clamping surfaces for easy clamping. In this embodiment, the pressure head 1 has a cylindrical structure, and four planes are milled flat on the cylindrical surface of the pressure head 1 for clamping and positioning when the pressure head 1 is replaced, which facilitates remote reinstallation of the pressure head 1 by remote operating components such as robotic arms.

[0052] In this embodiment, guide sleeves 21 are fitted inside both ends of the through hole of the pressure rod 2 to support and guide the connecting rod 3.

[0053] In summary, this embodiment provides a remotely replaceable pressure head for a high-level radioactive solid waste overcompressor, which can be used in the field of radioactive waste treatment. It aims to solve the problem that maintenance personnel cannot enter the hot chamber to replace the pressure head in a high-level radioactive environment, and can enable maintenance personnel to operate the corresponding operating mechanism outside the hot chamber to replace the pressure head remotely.

[0054] The structure mainly includes pressure rod 2 (or main pressure rod), guide sleeve 21, connecting rod 3, pressure head 1, and operating mechanism 4.

[0055] The main pressure rod is a stepped shaft. It passes through the shielding plate 5 and enters the hot chamber. The upper end of the main pressure rod is fixed to the operating mechanism 4, and the lower end is connected to the pressure head 1. The connecting rod 3 passes through the center of the main pressure rod, connects to the operating mechanism 4 at the upper end, and connects to the pressure head 1 at the lower end. The main pressure rod has a through hole in the center, and a guide sleeve 21 is inlaid at each of the upper and lower ends of the through hole. The lower end has a frustum-shaped countersunk hole, which is connected to the boss 12 of the pressure head 1.

[0056] The connecting rod 3 is a slender rod structure with a T-shaped head 31 at the lower end. During normal operation, the connecting rod 3 is connected to the pressure head 1 through the T-shaped head 31. The two wings of the T-shaped head 31 (i.e., double wings) tighten the pressure head 1. When the pressure head 1 needs to be replaced, the connecting rod 3 is rotated 90° to switch the phase of the T-shaped head 31 (i.e., to make its phase correspond to the T-shaped slot hole), and the pressure head 1 is disengaged from the connecting rod 3. The upper end of the connecting rod 3 is a stepped shaft with a thread at the top for installing the locking nut 43 of the operating mechanism 4. The section of the shaft below the thread of the connecting rod 3 has a square cross section and passes through the square hole of the rotary table 41. By rotating the rotary table 41, the connecting rod 3 can be rotated, thereby realizing the disengagement and tightening of the pressure head 1 and the connecting rod 3. The connecting rod 3 passes through the center of the main pressure rod and cooperates with the guide sleeve 21.

[0057] The upper part of the pressure head 1 is provided with a frustum-shaped boss 12, which is connected and guided to the lower end of the main pressure rod. The lower part of the pressure head 1 is cylindrical, and the upper center of the pressure head 1 has a T-shaped slot 11, which is connected to the T-shaped head 31 of the connecting rod 3.

[0058] The operating mechanism 4 mainly includes a base 44, a hinge bolt 443, a bearing 45, a rotary table 41, a lifting sleeve 42, and a locking nut 43. The bearing seat 441 is equipped with a pin 442, and the hinge bolt 443 is connected to the bearing seat 441 of the base 44 through the pin 442. The hinge bolt 443 can rotate within the bearing seat 441. The upper part of the inner hole of the rotary table 41 is a threaded hole, and the lower part is a square hole. The bearing 45 is installed on the outer circle of the lower end. When the rotary table 41 rotates, the square hole at the bottom drives the connecting rod 3 to rotate. The lifting sleeve 42 has a through hole in the center, through which the end of the connecting rod 3 passes and is fastened by the locking nut 43, realizing the axial connection between the connecting rod 3 and the lifting sleeve 42.

[0059] Example 2

[0060] The method for replacing the pressure head structure of the high-level radioactive solid waste overcompressor in this embodiment uses the pressure head structure of the high-level radioactive solid waste overcompressor in Embodiment 1. The method includes disassembly and installation steps.

[0061] The disassembly steps include:

[0062] The control mechanism 4 causes the connecting rod 3 to move axially, thereby causing the T-head 31 to stop tightening the pressure head 1;

[0063] Rotate the connecting rod 3, causing the T-head 31's double wings to align with the slot 111 at an angle;

[0064] The connecting rod 3 moves axially, causing the T-head 31 to push the pressure head 1 until the pressure head 1 separates from the pressure rod 2;

[0065] In accordance with the specific structure in Embodiment 1, when disassembling the pressure head 1, the lever is inserted into the through hole at the top of the lifting sleeve 42, and the lifting sleeve 42 is rotated to push the connecting rod 3 downward. The T-shaped head 31 of the connecting rod 3 is suspended in the T-shaped slot 11 of the pressure head 1 (the boss 12 of the pressure head 1 is also embedded in the frustum-shaped countersunk hole of the pressure rod 2); the hinge bolt 443 of the locking turntable 41 is loosened, and the turntable 41 is rotated 90°, which at the same time drives the T-shaped head 31 to rotate 90°, so that the long side of the T-shaped head 31 and the long slot of the T-shaped slot 11 of the pressure head 1 are in phase. The turntable 41 is locked with the hinge bolt 443 to keep the phase of the T-shaped head 31 stationary; the lever continues to rotate, the lifting sleeve 42 pushes the connecting rod 3 downward, and the T-shaped head 31 pushes the pressure head 1 downward until the pressure head 1 separates from the main pressure rod and falls onto the anvil plate 6. The main pressure rod is lifted to expose the pressure head 1, and the disassembled pressure head 1 is transported out by the transport device.

[0066] The installation steps include:

[0067] The control mechanism 4 causes the connecting rod 3 to rotate, which in turn causes the T-head 31's double wings to align with the slot 111 at an angle.

[0068] Move the connecting rod 3 axially to drive the T-head 31 into the T-slot 11, and then rotate the connecting rod 3 so that the two wings of the T-head 31 are offset from the slot 111.

[0069] Move the pressure rod 2, operating mechanism 4, and connecting rod 3 axially, causing the T-head 31 to tighten the pressure head 1 until the pressure head 1 and pressure rod 2 are completely in contact.

[0070] In accordance with the specific structure in Embodiment 1, when replacing the new pressure head 1, the transport device transfers the new pressure head 1 to the anvil plate 6. After aligning the pressure head 1 with the main pressure rod, the connecting rod 3 falls down, allowing the T-shaped head 31 to be inserted into the T-shaped slot 11 of the pressure head 1. The hinge bolt 443 of the rotary table 41 is loosened, and the table rotates 90° in the opposite direction. At the same time, the T-shaped head 31 rotates 90° in the opposite direction, so that the long side of the T-shaped head 31 and the long slot of the T-shaped slot 11 of the pressure head 1 are in a perpendicular phase. The rotary table 41 is locked with the hinge bolt 443 to keep the T-shaped head 31 in a fixed phase. The lever is inserted into the top through hole of the lifting sleeve 42 of the operating mechanism 4. The lifting sleeve 42 is rotated to pull the connecting rod 3 upward, lifting the pressure head 1 and the main pressure rod, so that the frustum-shaped countersunk hole of the main pressure rod is completely fitted with the boss 12 on the pressure head 1, thus completing the replacement of the pressure head 1.
