Description

Technical Field

[0001] The invention specifically relates to a pressure head structure, method and waste treatment equipment of a super press for high-level solid waste. Background Art

[0002] In the radioactive solid waste treatment process, high-level solid waste generally needs to be compressed by a super press. Since the waste is radioactive, the pressure head of the high-level solid waste super press is located in the hot chamber to treat the waste in the hot chamber. The pressure head needs to be replaced when it works for a long time or produces stress pitting and wear. However, the pressure head is directly in contact with the radioactive waste during operation and is contaminated, which makes it impossible for maintenance personnel to directly enter the hot chamber for replacement. If manual replacement is required, source removal treatment may be required, which greatly reduces production efficiency. In the prior art, there is a method of connecting the pressure rod and the pressure head by threading. However, this connection method may cause the threaded connection to loosen due to the rotation of the pressure head under load during long-term operation of the pressure head, and the connection stability is lacking. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a pressure head structure of a super press for high-level solid waste in view of the above-mentioned deficiencies in the prior art. The pressure head structure is reasonably arranged, can be replaced over a long distance, and is easy to disassemble and replace. The present invention also provides a replacement method for the pressure head structure of a super press for high-level solid waste and a waste treatment device.

[0004] The present invention provides a pressure head structure of a high-level solid waste super press, which is arranged through a shielding plate and comprises a pressure head, a pressure rod, a connecting rod and an operating mechanism. An axial through hole is arranged inside the pressure rod, the connecting rod is inserted into the through hole of the pressure rod, a T-shaped head is arranged on the tail section of the connecting rod located on the inner side of the shielding plate, and the first section of the connecting rod located on the outer side of the shielding plate is connected to the operating mechanism, a T-shaped slot hole is arranged on the pressure head, the slot of the T-shaped slot hole is a rectangular slot, and the length of the rectangle is greater than the double wings of the T-shaped head and the width is less than the double wings of the T-shaped head, the inside of the slot is a slot bottom that allows the double wings of the T-shaped head to rotate, and the operating mechanism can enable the connecting rod to drive the T-shaped head to rotate and adjust the relative angle between the double wings and the slot, so that the T-shaped head can enter or exit the T-shaped slot hole, and can enable the connecting rod to drive the T-shaped head to move axially, so that the T-shaped head tightens the pressure head to the pressure rod or pushes the pressure head away from the pressure rod.

[0005] Furthermore, the operating mechanism includes a rotating disk and a lifting sleeve. The rotating disk is rotatably connected to one end of the pressure rod located on the outside of the shielding plate. An axial through hole is provided inside the rotating disk. The first section of the connecting rod is arranged in the through hole of the rotating disk and is relatively fixed to the rotating disk in the axial rotation direction to achieve synchronous rotation with the rotating disk. The lifting sleeve is movably connected in the axial direction in the through hole of the rotating disk. The end of the first section of the connecting rod is relatively fixed to the axial direction of the lifting sleeve to achieve synchronous axial movement with the lifting sleeve.

[0006] Furthermore, a section of the through hole of the turntable that faces 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 except the end head is a special-shaped shaft section with a cross-section consistent with the special-shaped hole section. The special-shaped shaft section is inserted into the special-shaped hole section, so that while being able to move axially relative to the turntable, it is limited in the rotation direction around the axial direction by the special-shaped hole section, thereby realizing synchronous rotation with the turntable.

[0007] Furthermore, a section of the through hole of the turntable facing the outside of the shielding plate is a threaded hole section, and an external thread is provided on the outer surface of the lifting sleeve. The lifting sleeve penetrates into the through hole of the turntable and is threadedly connected with the threaded hole section to realize axial movable connection.

[0008] Furthermore, the operating mechanism also includes a locking nut, the inner hole surface of the locking nut is provided with an internal thread, the end of the first section of the connecting rod is a threaded shaft section with an external thread, the lifting sleeve is provided with a stepped hole, the locking nut is arranged in the large diameter hole section facing the outer side of the shielding plate, and the locking nut is axially limited by the step surface of the stepped hole, the threaded shaft section extends into the stepped hole of the lifting sleeve, and is threadedly connected with the locking nut, so that while it can rotate relative to the lifting sleeve, it is axially limited by the locking nut to achieve 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 is provided with a countersunk hole at the end facing the outer side of the shielding plate. The base is a cylindrical structure. The base is embedded in the countersunk hole and sleeved on the outside of the turntable. The inner surface of the base and the outer surface of the turntable are rotatably connected through a bearing.

[0010] Furthermore, the base is provided with a plurality of shaft seats, each shaft seat is evenly distributed around the axial direction of the pressure rod, the shaft seat is connected with a movable bolt via a pin shaft, the movable bolt can be flipped around the pin shaft in the shaft seat, and the end of the movable bolt passes through the turntable and is fastened by a nut.

[0011] Furthermore, the through hole of the pressure rod is provided with a truncated cone-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 is provided with a truncated cone-shaped boss. When the T-head tightens the pressure head onto the pressure rod, the boss is embedded in the truncated cone-shaped countersunk hole.

[0012] Furthermore, guide sleeves are provided inside both ends of the compression rod through hole for supporting and guiding the connecting rod.

[0013] The present invention also provides a method for replacing a pressure head structure of a high-level solid waste super press, wherein the pressure head structure of the high-level solid waste super press adopts the above-mentioned pressure head structure of the high-level solid waste super press, and the method comprises a disassembly step and an installation step.

[0014] The disassembly step comprises:

[0015] Control the operating mechanism to make the connecting rod move axially, so that the T-head no longer tightens the pressure head;

[0016] Make the connecting rod rotate, driving the two wings of the T-head to correspond to the angle of the notch;

[0017] Make the pressure rod, operating mechanism and connecting rod move axially, drive the T-head to push the pressure head until the pressure head is separated from the pressure rod;

[0018] The installation steps include:

[0019] Control the operating mechanism to make the connecting rod rotate, driving the two wings of the T-head to correspond to the angle of the notch;

[0020] Make the connecting rod move axially to drive the T-head into the T-slot hole, and then make the connecting rod rotate to make the angle of the two wings of the T-head staggered with the slot;

[0021] Make the connecting rod move axially, driving the T-head to tighten the pressure head until the pressure head and the pressure rod are completely fitted together.

[0022] The present invention also provides a waste treatment equipment, including a super press, a hot chamber and an anvil, wherein the anvil is arranged inside the hot chamber, and the super press includes a pressure head structure, which is the above-mentioned high-level solid waste super press pressure head structure. The pressure head structure penetrates the shielding plate of the hot chamber and cooperates with the anvil to complete the compression of the waste.

[0023] The pressure head structure of the high-level solid waste super press of the present invention has an axial through hole inside the pressure rod, a connecting rod is inserted into the through hole of the pressure rod, a T-shaped head is provided on the tail section of the connecting rod located on the inner side of the shielding plate, the first section of the connecting rod located on the outer side of the shielding plate is connected to the operating mechanism, and a T-shaped slot hole is provided on the pressure head for active connection with the T-shaped head.

[0024] The matching connection between the T-head and the T-slot hole 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. The double wings of the T-head can further tighten the pressure head, not only achieving the fit between the pressure head and the pressure rod, but also ensuring that the two can be tightly pressed.

[0025] The connecting rod serves as a transmission rod for disassembly and installation. It can transmit the operating action of the operating mechanism on the outside of the shielding plate to the T-head on the inside of the shielding plate, thereby realizing the rotation and axial movement of the T-head, and thus realizing the detachment and installation of the inner pressure head through operation on the outside. Therefore, even if the pressure head is contaminated by handling radioactive waste during operation, it can be replaced and repaired in time without the need for personnel to enter the radioactive environment. This is not only more efficient, but also effectively ensures the safety of personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, the pressure head structure of the high-level solid waste super press of this embodiment is arranged through the shielding plate 5, including a pressure head 1, a pressure rod 2, a connecting rod 3 and an operating mechanism 4. The pressure rod 2 is provided with an axial through hole inside, and the connecting rod 3 is inserted into the through hole of the pressure rod 2. Figure 6 As shown, the end 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 in FIG. Figure 4 and Figure 5 As shown, the pressure head 1 is provided with a T-shaped slot hole 11, and the slot 111 of the T-shaped slot hole 11 is a rectangular slot, and the length of the rectangle is greater than the double wings of the T-shaped head 31, and the width is less than the double wings of the T-shaped head 31. The inside of the slot 111 is a slot bottom 112 that allows the double wings of the T-shaped head 31 to rotate. The operating mechanism 4 can make the connecting rod 3 drive the T-shaped head 31 to rotate and adjust the relative angle between the double wings and the slot 111, as shown in FIG. Figure 7 and Figure 8 As shown, the T-shaped head 31 can enter or exit the T-shaped slot hole 11, and the connecting rod 3 can drive the T-shaped head 31 to move axially, so that the T-shaped head 31 tightens the pressure head 1 to the pressure rod 2 or pushes the pressure head 1 away from the pressure rod 2.

[0041] In this embodiment, the matching connection mode of the T-head 31 and the T-slot hole 11 will not loosen due to the force applied by the pressure head 1, and the operation is simple and reliable. The connection and disconnection of the two can be completed by rotation and axial movement, and the double wings of the T-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 tightly pressed.

[0042] The connecting rod 3 serves as a transmission rod for disassembly and installation, and can transmit the operating action of the operating mechanism 4 on the outside of the shielding plate 5 to the T-head 31 on the inside of the shielding plate 5, so as to realize the rotation and axial movement of the T-head 31, thereby realizing the detachment and installation of the inner pressure head 1 through the operation on the outside. Therefore, even if the pressure head 1 is contaminated when handling radioactive waste during operation, it can be replaced and repaired in time without the need for personnel to enter the radioactive environment. This is not only more efficient, but also effectively ensures the safety of personnel.

[0043] In this embodiment, Figure 3 As shown, the operating mechanism 4 includes a rotating disk 41 and a lifting sleeve 42. The rotating disk 41 rotates around the axial direction of the connecting rod 3 and is connected to one end of the pressure rod 2 located outside the shielding plate 5. An axial through hole is provided inside the rotating disk 41. The first section of the connecting rod 3 is arranged in the through hole of the rotating disk 41 and is relatively fixed with the rotating disk 41 in the rotating direction around the axial direction to achieve synchronous rotation with the rotating disk 41. The lifting sleeve 42 is axially movably connected in the through hole of the rotating disk 41. The end of the first section of the connecting rod 3 is relatively fixed with the lifting sleeve 42 in the axial direction to achieve synchronous axial movement with the lifting sleeve 42. That is, the connecting rod 3 is relatively fixed with the rotating disk 41 in the rotating direction, so that it rotates synchronously with the rotating disk 41 without affecting the axial movement, and is relatively fixed with the lifting sleeve 42 in the axial direction, so that it moves synchronously with the lifting sleeve 42 in the axial direction without affecting the rotation. This arrangement separates the rotation and axial movement of the connecting rod 3 to avoid mutual interference. During operation, by controlling the rotation of the turntable 41 and the axial movement of the lifting sleeve 42 respectively, the connecting rod 3 can correspondingly drive the T-head 31 to complete corresponding actions.

[0044] In this embodiment, a section of the through hole of the rotating disk 41 that faces the inner side of the shielding plate 5 is a special-shaped hole section 412, and the shaft section of the first section of the connecting rod 3 except the end is a special-shaped shaft section 33 with the same cross section as the special-shaped hole section 412. The special-shaped shaft section 33 is inserted into the special-shaped hole section 412, so that while being able to move axially relative to the rotating disk 41, it is limited in the rotation direction around the axial direction by the special-shaped hole section 412 to achieve synchronous rotation with the rotating disk 41. The cross-sections of the special-shaped hole section 412 and the special-shaped shaft section 33 can adopt other shapes besides the coaxial circle with the connecting rod 3, ensuring that the limit between the cross-sections can enable the special-shaped hole section 412 to provide torque for driving the special-shaped shaft section 33. In this embodiment, the special-shaped hole section 412 and the special-shaped shaft section 33 both adopt a square cross-sectional structure, and various structures such as pentagons, hexagons, and ellipses can also be adopted in other embodiments.

[0045] In this embodiment, a section of the through hole of the rotating disk 41 that faces the outside of the shielding plate 5 is a threaded hole section 411, and an external thread is provided on the outer surface of the lifting sleeve 42. The lifting sleeve 42 is inserted into the through hole of the rotating disk 41 and is threadedly connected with the threaded hole section 411 to achieve axial movable connection. The threaded connection method can not only achieve stepless adjustment of the axial movement of the lifting sleeve 42, but also achieve precise control of the moving length by the number of twisted threads, which is suitable for precise control of the movable position of the T-head.

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

[0047] In this embodiment, the operating mechanism 4 further includes a locking nut 43, the inner hole surface of the locking nut 43 is provided with an internal thread, the end of the first section of the connecting rod 3 is a threaded shaft section 32 with an external thread, and the lifting sleeve 42 is provided with a stepped hole inside, and the locking nut 43 is placed in the large diameter hole section facing the outside of the shielding plate 5, and the locking nut 43 is axially limited by the step surface of the stepped hole, and the threaded shaft section 32 extends into the stepped hole of the lifting sleeve 42 and is threadedly connected with the locking nut 43, so that while being able to rotate relative to the lifting sleeve 42, the locking nut 43 is axially limited by the locking nut 43 to achieve synchronous axial movement with the lifting sleeve 42. That is, when the lifting sleeve 42 rises, the step surface drives the locking nut 43 and the connecting rod 3 to rise together, and when the lifting sleeve 42 falls, the connecting rod 3 falls under the influence of gravity, and due to the limitation of the step surface, the fall is synchronized with the lifting sleeve 42. In this embodiment, the locking nut 43 is a sleeve structure with a sealed bottom, the inner hole of which is threaded, and is connected to the end of the connecting rod 3 for fastening. A hexagonal through hole is provided at the upper bottom, which can be used to operate the locking nut 43 with a wrench to rotate.

[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 is provided with a countersunk hole at the end facing the outside of the shielding plate 5. The base 44 is a cylindrical structure. The base 44 is embedded in the countersunk hole and sleeved on the outside of the rotating disk 41. The inner surface of the base 44 and the outer surface of the rotating disk 41 are rotatably connected through 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 through a fastener. The inner surface of the base 44 is connected to the outer ring of the bearing 45, and the outer surface of the rotating disk 41 is connected to the inner ring of the bearing 45.

[0049] In this embodiment, a plurality of shaft seats 441 are provided on the base 44, which are specifically arranged on the upper end surface of the base 44. Each shaft 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 shaft seats 441 are evenly distributed on the circumference of the flange disk surface of the first flange 444 of the base 44. A movable bolt 443 is connected to the shaft seat 441 through a pin shaft 442. The movable bolt 443 can be turned around the pin shaft 442 in the shaft seat 441; a U-shaped groove is provided at a position corresponding to the shaft seat 441 on the outer circumference of the rotating disk 41 for connecting The pivot bolt 443, the end of the pivot bolt 443 passes through the turntable 41 and is fastened by a nut. Specifically, after the pivot bolt 443 is flipped upward and placed in the U-shaped groove, the upper end of the pivot bolt 443 is tightened by a nut, so that after the turntable 41 is rotated to a desired angle, the pivot bolt 443 is used to fasten it. Specifically, the outer surface of the turntable 41 is provided with a second flange 413 located above the shaft seat 441, and the flange surface of the second flange 413 is provided with four U-shaped grooves, so that the pivot bolt 443 can be flipped upward to lock the turntable 41.

[0050] In this embodiment, the through hole of the pressure rod 2 is provided with a truncated cone-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 is provided with a truncated cone-shaped boss 12, and when the T-head 31 tightens the pressure head 1 onto the pressure rod 2, the boss 12 is embedded in the truncated cone-shaped countersunk hole. The side of the truncated cone-shaped structure is an inclined surface, which can not only realize the embedded connection of the boss 12 and strengthen the connection strength between the pressure head 1 and the pressure rod 2, but also play a guiding role, and realize the automatic centering 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 is a cylindrical structure, and four planes are milled on the cylindrical surface of the pressure head 1 for clamping and positioning when the pressure head 1 is replaced, so as to facilitate remote operation components such as a manipulator to reinstall the pressure head 1 over a long distance.

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

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

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

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

[0056] The connecting rod 3 is a slender rod structure, and the lower end is a T-head 31 structure. During normal operation, the connecting rod 3 is connected to the pressure head 1 through the T-head 31, and the two wings (i.e., double wings) of the T-head 31 tighten the pressure head 1. When the pressure head 1 needs to be replaced, the phase of the T-head 31 is switched by rotating the connecting rod 3 90° (i.e., making its phase correspond to the T-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, and the uppermost part is a thread, which is used to install the locking nut 43 of the operating mechanism 4; a section of the shaft under the thread of the connecting rod 3 is a square cross-section, which is inserted into the square hole of the turntable 41. By rotating the turntable 41, the connecting rod 3 can be driven to rotate, 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] A truncated cone-shaped boss 12 is provided on the upper part of the pressure head 1, which is connected and guided with the lower end of the main pressure rod. The lower part of the pressure head 1 is cylindrical, and a T-shaped slot hole 11 is opened in the center of the upper part of the pressure head 1, which is connected with the T-shaped head 31 of the connecting rod 3.

[0058] The operating mechanism 4 mainly includes a base 44, a movable bolt 443, a bearing 45, a rotating disk 41, a lifting sleeve 42 and a locking nut 43. The shaft seat 441 is equipped with a pin shaft 442, and the movable bolt 443 is connected to the shaft seat 441 of the base 44 through the pin shaft 442. The movable bolt 443 can be turned over in the shaft seat 441; the upper part of the inner hole of the rotating disk 41 is a threaded hole, the lower part is a square hole, and the outer circle of the lower end is equipped with a bearing 45. When the rotating disk 41 rotates, the bottom square hole drives the connecting rod 3 to rotate; the lifting sleeve 42 is provided with a through hole in the center, and the end of the connecting rod 3 passes through it and is fastened by the locking nut 43 to realize 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 solid waste super press in this embodiment adopts the high-level solid waste super press structure in Example 1. The method includes a disassembly step and an installation step.

[0061] The disassembly steps include:

[0062] Control the operating mechanism 4 to make the connecting rod 3 move axially, so that the T-shaped head 31 no longer tightens the pressing head 1;

[0063] The connecting rod 3 is rotated to drive the two wings of the T-shaped head 31 to correspond to the angle of the notch 111;

[0064] Make the connecting rod 3 move axially, drive the T-shaped head 31 to push the pressure head 1 until the pressure head 1 is separated from the pressure rod 2;

[0065] In combination with the specific structure in Example 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, and the T-head 31 of the connecting rod 3 is suspended in the T-slot hole 11 of the pressure head 1 (the boss 12 of the pressure head 1 is also embedded in the truncated cone-shaped countersunk hole of the pressure rod 2); loosen the swing bolt 443 of the locking rotary disk 41, rotate the rotary disk 41 90°, and at the same time drive the T-head 31 to rotate 90°, so that the long side of the T-head 31 and the long groove direction of the T-slot hole 11 of the pressure head 1 are in phase, and the rotary disk 41 is locked with the swing bolt 443 to keep the phase of the T-head 31 unchanged; the lever continues to rotate the lifting sleeve 42 to push the connecting rod 3 downward, and the T-head 31 pushes the pressure head 1 downward until the pressure head 1 is separated from the main pressure rod and falls on the anvil 6, the main pressure rod is lifted to expose the pressure head 1, and the disassembled pressure head 1 is transported out by the carrying device.

[0066] The installation steps include:
