Description

Technical Field

[0001] This utility model belongs to the technical field of disassembly tools for synthesis reactors, and specifically relates to a disassembly tool for the bottom valve screw of a synthesis reactor. Background Technology

[0002] A synthesis reactor is a reactor designed to synthesize chemical substances under specific temperature and pressure conditions. It is widely used in scientific research experiments in fields such as new materials, energy, and environmental engineering, and is a commonly used small reactor in universities and research institutions for scientific research.

[0003] like Figure 1 As shown, the bottom of the synthesis reactor 10 typically adopts a concave structure design, with a valve (also called a bottom valve) 20 at its bottom. The bottom valve 20 is connected to the reactor body of the synthesis reactor 10 via a bottom valve screw 30. After a period of use, it is usually necessary to disassemble the bottom valve screw 30 at the bottom of the synthesis reactor 10 for maintenance. Since the reaction process conditions of the synthesis reactor 10 are mostly high temperature and high pressure environments, the bottom valve screw 30 is prone to excessive thread engagement due to thermal expansion and chemical corrosion. Moreover, the portion of the bottom valve screw 30 protruding from the synthesis reactor 10 is only 2-3 cm. Because there are also multiple auxiliary pipelines 40 at the bottom valve 20, it is difficult for pipe wrenches and spanners to reach into the concave area, making disassembly difficult. Traditional disassembly methods cannot directly disassemble the bottom valve screw 30; they can only first remove the auxiliary pipelines 40 of the bottom valve 20 before disassembling the bottom valve 20, which has the following drawbacks:

[0004] First, traditional disassembly tools (such as pipe wrenches or wrenches) are not compatible with the concave structure at the bottom of the synthesis reactor 10, limiting the operating space.

[0005] Secondly, traditional dismantling methods require the removal of multiple sections of auxiliary pipelines 40, which is a complex, time-consuming, and labor-intensive process. Furthermore, the dismantling and reassembling of auxiliary pipelines 40 can easily lead to risks such as media leakage and mechanical damage.

[0006] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0007] The purpose of this utility model is to provide a simple and easy-to-operate tool for disassembling the bottom valve screw of a synthesis reactor, which can adapt well to the concave structure at the bottom of the synthesis reactor and disassemble the bottom valve screw.

[0008] To achieve the above objectives, this utility model adopts the following technical solution:

[0009] A tool for disassembling the bottom valve screw of a synthesis reactor includes a rod body and a chuck assembly disposed at one end of the rod body. When the chuck assembly is placed vertically, the angle between the rod body and the horizontal plane is 30°-45°. The chuck assembly includes a central column, a movable knob portion sleeved on the central column, and a guide sleeve disposed on the knob portion. The knob portion includes a fastening knob and a threaded post fixed below the fastening knob. The guide sleeve has a hollow structure, and its inner side has an internal thread section that threadedly engages with the threaded post. The lower part of the guide sleeve is shaped like an inverted frustum. A plurality of guide grooves are evenly spaced in a ring on the inner side of the lower part of the sleeve. Each guide groove is arranged longitudinally and has a jaw for holding the bottom valve screw. Each jaw is located below the threaded post. A placement groove is opened on the side of the jaw facing the guide groove. The placement groove is arranged along the length of the jaw and has a spring inside. A limiting baffle for resisting the spring is provided on the guide groove. The limiting baffle extends into the placement groove. When the fastening knob is tightened toward the guide sleeve, the jaw is pushed out of the guide sleeve.

[0010] Furthermore, the guide sleeve is provided with three guide grooves, each of which is evenly spaced around the axis of the guide sleeve.

[0011] Furthermore, the gripper includes a guide block slidably disposed within the guide groove and a clamping portion disposed at the bottom of the guide block, with the top of each guide block located below the threaded post.

[0012] Furthermore, each of the clamping parts has protruding teeth on the side that is close to each other.

[0013] Furthermore, friction blocks are provided on both sides of the bottom of the guide groove, and the guide block is disposed between the friction blocks on both sides. Sliding grooves are provided on both sides of the guide block corresponding to the positions of the friction blocks.

[0014] Furthermore, the outer side of the fastening knob is provided with anti-slip protrusions.

[0015] Furthermore, the end of the rod away from the clamp assembly is also provided with a grip portion, which is designed to prevent slippage.

[0016] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0017] I. The disassembly tool of this utility model has a simple structure. Through the angle design of the rod, the clamp assembly can be easily inserted into the concave part of the synthesis vessel, which has good adaptability. Furthermore, through the knob, the claws inside the guide sleeve can extend out of the guide sleeve to clamp the bottom valve screw. Then, by rotating the rod, the bottom valve screw is rotated in the loosening direction, thereby disassembling the bottom valve screw. This method of directly disassembling the bottom valve screw is simple to operate. Compared with the traditional disassembly method, it avoids the operation of removing auxiliary pipelines, saving time and effort, and also avoids the risks caused by removing auxiliary pipelines.

[0018] 2. A placement groove is provided on the inner side of the guide block facing the guide sleeve. A spring is installed in the placement groove, and a limiting baffle for fixing the spring is provided on the guide groove. When the threaded column applies pressure to the guide block and pushes the guide block out of the guide sleeve, so that the clamping parts on the three guide blocks clamp the bottom valve screw, the guide block will apply pressure to the spring in the placement groove. The spring is compressed by the guide block under the action of the limiting baffle. When the bottom valve screw is disassembled, it is necessary to loosen the clamp assembly from the bottom valve screw. By loosening the fastening knob, the pressure of the threaded column on the guide block disappears, and the guide block returns to its original position under the rebound of the spring. This design can increase the convenience of operation of the disassembly tool of this utility model. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1 to 6As shown, a disassembly tool for the bottom valve screw of a synthesis reactor includes a rod body 1 and a chuck assembly disposed at one end of the rod body 1. The chuck assembly includes a central column 2, a movable knob part 3 sleeved on the central column 2, and a guide sleeve 4 disposed on the knob part 3. Specifically, the movable installation method of the knob part 3 and the central column 2 can adopt a conventional method in the art, such as a threaded connection, that is, the lower part of the central column 2 is provided with an external thread (not shown in the figure), and the middle part of the knob part 3 is provided with an internal thread (not shown in the figure) that mates with the external thread. The knob part 3 includes a fastening knob 31 and a threaded post 32 fixed below the fastening knob 31. The guide sleeve 4 has a hollow structure, and the inner side of the guide sleeve 4 is provided with an internal thread section that mates with the threaded post 32. The guide sleeve 4 is threadedly connected to the threaded post 32 through the internal thread section. The upper part of the guide sleeve 4 is cylindrical, and the internal thread section is disposed on the upper part of the guide sleeve 4. The lower part of the guide sleeve 4 is shaped like an inverted frustum. The guide sleeve 4 is integrally connected to the lower part. A number of guide grooves 41 are evenly spaced in a ring on the inner side of the lower part. Each guide groove 41 is longitudinally arranged, and each guide groove 41 contains a gripper 42 for holding the bottom valve screw 30. Each gripper 42 is located below the threaded post 32. A placement groove 423 is formed on the side of the gripper 42 facing the guide groove 41. The placement groove 423 is arranged along the length of the guide block 421, and a spring 424 is installed inside the placement groove 423. The groove 41 is provided with a limiting baffle 411 for resisting the spring 424. The limiting baffle 411 extends into the placement groove 423. The gripper 42 abuts against the spring 424 through the placement groove 423. Due to the resisting effect of the limiting baffle 411 on the spring, the spring 423 can support the gripper 42 and prevent the gripper 42 from slipping off the guide groove 41. When the fastening knob 31 is tightened, the threaded post 32 applies pressure to the gripper 42 and pushes the guide block 421 out of the guide sleeve 4.

[0039] Preferably, in this embodiment, the guide sleeve 4 is provided with three guide grooves 41, and each guide groove 41 is evenly spaced around the axis of the guide sleeve 4; preferably, in this embodiment, the gripper 42 includes a guide block 421 slidably disposed in the guide groove 41 and a clamping part 422 integrally formed on the bottom of the guide block 421, and the top of each guide block 421 is located below the central column 2. Preferably, the side of each clamping part 422 that is close to each other is provided with protruding teeth, which can increase the friction.

[0040] like Figure 2 As shown, when the chuck assembly is placed vertically, the angle between the rod 1 and the horizontal plane M is 30°-45°, which makes it easy for the operator to insert the chuck assembly into the concave part at the bottom of the synthesis vessel 10. Preferably, in this embodiment, the angle between the rod 1 and the horizontal plane is 30°. After multiple tests, this angle has good compatibility with the concave part at the bottom of the synthesis vessel 10.

[0041] With this setup, when it is necessary to disassemble the bottom valve screw 30, hold the rod body 1 by hand and insert the rod body 1 into the recessed area at the bottom of the synthesis vessel 10, so that the chuck assembly is aligned with the bottom valve screw 30. Then, tighten the fastening knob 31 towards the guide sleeve 4 by hand or other tools, so that the threaded post 32 moves in the guide sleeve 4 towards the guide block 421. The threaded post 32 applies pressure to the guide block 421, pushing the guide block 421 out of the guide sleeve 4. The guide block 421 moves along the guide groove 41 towards the outside of the guide sleeve 4, so that... The spacing between the clamping parts 422 on the three guide blocks 421 gradually decreases until the three clamping parts 422 clamp the bottom valve screw 30. Since the guide sleeve 4 is set in the shape of an inverted frustum, when the threaded column 32 pushes the guide block 421 outward, the force on the guide block 421 will be divided by the inner inclined surface of the guide sleeve 4 into a force perpendicular to the inclined surface and an outward force, so as to achieve the effect of the tighter it is, the less likely it is to loosen. At this time, rotate the rod body 1 to rotate the bottom valve screw 30 in the direction of loosening, thereby disassembling the bottom valve screw 30.

[0042] When the clamping parts 422 on the three guide blocks 421 clamp the bottom valve screw 30, the guide blocks 421 will apply pressure to the spring 424 in the placement groove 423. The spring 424 is compressed by the guide blocks 421 under the action of the limiting baffle 411. When the bottom valve screw 30 is disassembled, and the chuck assembly needs to be released from the bottom valve screw 30, the fastening knob 31 is loosened. The pressure of the threaded column 32 on the guide block 421 disappears, and the guide block 421 returns to its original position under the rebound action of the spring 424. This setting can increase the convenience of operation of the disassembly tool of this utility model.

[0043] The disassembly tool of this utility model has a simple structure. Through the angle design of the rod body 1, the clamp assembly can be easily inserted into the concave part of the synthesis vessel 10, which has good adaptability. Furthermore, through the knob part 3, the clamp 42 inside the guide sleeve 4 can extend out of the guide sleeve 4 to clamp the bottom valve screw 30. Then, by rotating the rod body 1, the bottom valve screw 30 is rotated in the loosening direction, thereby removing the bottom valve screw 30. This method of directly disassembling the bottom valve screw 30 is simple to operate. Compared with the traditional disassembly method, it avoids the operation of removing the auxiliary pipeline 40, saving time and effort, and also avoids the risks caused by removing the auxiliary pipeline 40.

[0044] Preferred, such as Figure 2 and Figure 3 As shown, the outer side of the fastening knob 31 is provided with anti-slip protrusions 311, and the end of the rod 1 away from the clamp assembly is also provided with a grip part 11. The grip part 11 is designed to be anti-slip and to increase friction.

[0045] Preferred, such as Figure 4As shown, friction blocks 412 are provided on both sides of the bottom of the guide groove 41, and the guide block 421 is positioned between the friction blocks 412 on both sides. Sliding grooves 4211 are provided on both sides of the guide block 421 corresponding to the positions of the friction blocks 412. The friction blocks 412 are embedded in the sliding grooves 4211. The friction blocks 412 are made of flexible or elastic materials. This arrangement can improve the sliding effect of the guide block 421.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
