Description

Technical Field

[0001] This utility model relates to the field of purification technology for monovinyl diethylene glycol ether, and more specifically, to a purification apparatus for monovinyl diethylene glycol ether. Background Technology

[0002] Existing technologies for purifying monovinyl diethylene glycol ether (MDG) have several technical bottlenecks, particularly in the connection and disassembly of pipelines within the purification system. Current technologies typically require multiple sets of pipelines to connect purification equipment such as distillation columns, condensers, and storage tanks, using a pipeline transport system to transfer and transport MEG during the purification process. While this pipeline connection method achieves basic material transport, it presents significant operational inconveniences in practical applications. Connecting and disassembling pipelines in existing technologies is usually cumbersome, requiring the assistance of wrenches, pipe wrenches, or specialized disassembly tools. When personnel need to perform regular inspections and maintenance on pipelines at the production site, or replace and clean blocked or damaged pipelines, they cannot complete the disassembly, maintenance, and replacement work in a timely manner if they do not have the appropriate tools or if the tools are not suitable for the actual needs. This dependence on tools not only increases the complexity and time cost of operations, but also affects the continuity of purification operations and production efficiency. Especially in scenarios where the pipeline layout needs to be quickly adjusted or damaged pipe sections need to be replaced urgently during the purification production process, workers often cannot handle the situation in a timely manner due to incomplete tools, and may also cause damage to pipeline interfaces or sealing structures due to improper tool operation, reducing the practicality and ease of maintenance of the purification equipment.

[0003] Furthermore, although some equipment has technically attempted to achieve tool-free and convenient connection and disconnection between pipelines through the cooperation of different components, these improved devices often have relatively simple connection structure designs and insufficient stability of the fixing mechanism. They are unable to withstand the internal pressure generated by the material conveying pipeline during use and the influence of the external environment. With the use of purification equipment, the pipeline connection parts are prone to displacement or even accidental unlocking and detachment due to external forces such as pressure fluctuations caused by the flow of materials inside the pipeline and vibration and impact during the operation of the purification equipment. This instability can lead to problems such as sudden loosening of pipeline connections, misalignment of interface positions, or accidental detachment of connection parts during use. This not only affects the sealing of material conveying and the efficiency of purification work, but may also cause material leakage due to accidental detachment of pipelines, resulting in environmental pollution or production safety hazards.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a purification apparatus for monovinyl diethylene glycol ether, which has the following beneficial effects:

[0017] 1. By setting up a linkage structure of drive frame, drive rod, connecting pipe, insertion pipe, embedding rod, moving sleeve, and threaded block, the tool-free connection and disconnection function between pipelines in the purification unit is realized. When it is necessary to disassemble the connecting pipe, the operator only needs to rotate the drive frame forward to drive the moving sleeve along the threaded groove, so that the embedding rod slides out of the fitting groove. The pipeline can be quickly disassembled, installed, maintained, and replaced without the need for wrenches, pipe wrenches, or special disassembly tools. This effectively solves the problem of cumbersome pipeline connection and disassembly operations that require tool assistance in the existing technology, and avoids the situation where disassembly, installation, maintenance, and replacement cannot be completed in time due to incompatible tool models or incomplete tools. It reduces the complexity of operation and time costs, improves the continuity and production efficiency of purification operations, and avoids the problem of damage to pipeline interface parts or sealing structure caused by improper tool operation.

[0018] 2. By setting a locking structure consisting of a running sleeve, running rod, rotating plate, and rotating hole on the outside of the connecting pipe, and a stabilizing mechanism consisting of a swing rod, actuating frame, actuating groove, and driving frame on the outside of the connecting pipe, a stable locking function is achieved after the pipeline connection. After installation, the running rod supports and limits the running sleeve to one side of the rotating plate, and works with the guide block and guide groove to limit the running sleeve and prevent it from moving. At this time, the running sleeve, swing rod, actuating frame, and actuating groove work together to limit the rotation of the driving frame. Multiple components work together to form a stable protection mechanism, which effectively solves the problem of insufficient stability of the connection structure in the existing technology. It prevents the connection from being displaced or even accidentally unlocked and detached due to external forces such as pressure fluctuations caused by the flow of materials inside the pipeline and vibration impacts during the operation of the purification equipment. It avoids problems such as sudden loosening of the pipeline connection, misalignment of the interface, or accidental detachment of the connecting parts during use, ensuring the sealing of material transportation and the efficiency of purification work, and preventing environmental pollution or production safety hazards caused by material leakage due to accidental detachment of the pipeline.

A connecting pipe 5 detachably mounted inside the connecting pipe 4 is provided. A drive frame 6 is rotatably mounted on the outside of the connecting pipe 4, a drive rod 7 is fixedly mounted inside the drive frame 6, a sliding sleeve 8 is slidably mounted on the outside of the connecting pipe 4, and the sliding sleeve 8 is slidably connected to the drive rod 7. A mating block 9 is fixedly mounted on the outside of the connecting pipe 4, and an embedded rod 10 is slidably mounted on the side wall of the connecting pipe 4. Multiple actuation slots 11 are opened on one side of the drive frame 6, and multiple actuation frames 12 are fixedly mounted on the outside of the connecting pipe 4. The inner side of the actuation frame 12... A swing rod 13 is rotatably provided, with one end of the swing rod 13 inserted into the action groove 11. A running sleeve 14 is provided on the outside of the connecting pipe 4, and a running rod 15 is fixedly connected to one side of the running sleeve 14. A rotating plate 16 is rotatably provided on the outside of the connecting pipe 4, and a configuration block 17 is connected to one side of the rotating plate 16. A configuration spring 18 is connected to one side of the configuration block 17, and the other end of the configuration spring 18 is connected to the mating block 9. A rotating hole 19 is provided on the rotating plate 16. A sliding plate 20 is fixedly connected to one end of the embedded rod 10. A fitting groove 21 is provided on the outside of the insertion pipe 5, and the other end of the embedded rod 10 is inserted into the fitting groove 21. A threaded groove 22 is spirally provided on the outside of the connecting pipe 4, and a threaded block 23 is fixedly provided on the inside of the moving sleeve 8.

[0029] The purification component 2 is equipped with connecting pipes 24 above the tank lid 3 and below the storage tank 1. Both ends of the connecting pipes 24 are connected to the insertion pipes 5. Multiple connecting pipes 4 are installed on the top of the tank lid 3 and on the purification component 2.

[0030] In this embodiment, when the connecting pipe 24 needs to be removed for maintenance and replacement, the rotating plate 16 is first rotated clockwise, causing the rotating plate 16 to drive the configuration block 17 on one side to rotate clockwise. Then, the configuration block 17 will drive the configuration rod 29 on one side to rotate clockwise along the configuration hole 30. The configuration block 17 will cooperate with the mating block 9 to compress the configuration spring 18. At the same time, the rotating plate 16 will drive the rotating hole 19 to rotate clockwise. When the configuration spring 18 is compressed to its limit, the rotating hole 19 will just rotate to a position concentric with the running rod 15, and then push the running sleeve 14 to make the running... The sleeve 14 drives the inner guide block 33 to slide along the guide groove 32, and the running sleeve 14 will drive the running rod 15 on one side to gradually slide into the rotating hole 19. At the same time, the running sleeve 14 will cooperate with the rotating plate 16 to squeeze the push spring 28, so that the running sleeve 14 will gradually no longer limit one end of the swing rod 13. Then the drive frame 6 will rotate in the forward direction, and the drive frame 6 will drive the multiple action grooves 11 opened on one side to rotate. Then the inner wall of the action groove 11 will squeeze one end of the swing rod 13. Due to the rounded corner design of the inner wall of the action groove 11 and the end of the swing rod 13, and the swing... The moving rod 13 is rotatably connected to the actuating frame 12. Then, the actuating groove 11 will squeeze one end of the swing rod 13 out, causing the swing rod 13 to rotate within the actuating frame 12, and causing the other end of the swing rod 13 to rotate inwards. Simultaneously, the driving frame 6 will drive the driving rod 7 to rotate forward, causing the driving rod 7 to drive the two moving sleeves 8 to rotate synchronously in the same direction. Then, the moving sleeves 8 will drive the inner threaded block 23 to slide along the threaded groove 22. Since the two threaded grooves 22 are designed with opposing structures, the two moving sleeves 8 will synchronously drive the inner threaded block 23 along the driving groove 22. The rod 7 slides to both sides, increasing the distance between the two sliding sleeves 8. Then, the inner wall of the sliding sleeve 8 gradually stops limiting the outer wall of the sliding plate 20. Then, the return spring 31 returns to its original position and pushes the sliding plate 20, causing the sliding plate 20 to drive one side of the embedded rod 10 to slide outward. This causes one end of the embedded rod 10 to gradually slide out of the fitting groove 21. Then, the insertion tube 5 is pulled to one side to remove the insertion tube 5. Then, the insertion tube 5 at the other end of the connecting tube 24 is removed by referring to the above steps. Then, the connecting tube 24 can be removed for maintenance and replacement.

[0031] Please see Figures 3-5 As a further implementation of the overall equipment: a sealing sleeve 25 is detachably provided on the outside of the insertion tube 5, one end of the embedding rod 10 and one side of the inner wall of the fitting groove 21 are both designed with an angled structure, multiple fitting grooves 26 are opened on the inner side of the connecting tube 4, and multiple sealing rings 27 are fixedly provided on the outside of the insertion tube 5, and the sealing rings 27 are inserted into the corresponding fitting grooves 26.

[0032] A push spring 28 is movably sleeved on the outside of the running rod 15. One end of the push spring 28 is connected to the running sleeve 14, and the other end of the push spring 28 is in contact with the rotating plate 16.

[0033] A configuration rod 29 is connected to one side of the configuration block 17, and a configuration hole 30 is opened in the mating block 9. The configuration spring 18 is movably sleeved on the outside of the configuration rod 29, and one end of the configuration rod 29 slides into the configuration hole 30.

[0034] A return spring 31 is connected to one side of the sliding plate 20, and the other end of the return spring 31 is connected to the outer wall of the connecting pipe 4.

[0035] A guide groove 32 is provided on the outside of the connecting pipe 4, and a guide block 33 is slidably provided in the guide groove 32. The guide block 33 is fixedly installed inside the running sleeve 14.

[0036] The two transition sleeves 8 are arranged opposite each other, and the two threaded grooves 22 are opened opposite each other. The threaded block 23 slides in the threaded groove 22.

[0037] More specifically, when the connecting pipe 24 needs to be reconnected, first insert the plug 5 connected to one end of the connecting pipe 24 into the connecting pipe 4, so that the plug 5 abuts against the sealing sleeve 25. Then, rotate the drive frame 6 in the opposite direction, so that the drive frame 6 drives the multiple action slots 11 opened on one side to rotate in the opposite direction. At the same time, the drive frame 6 drives the two moving sleeves 8 to rotate in the opposite direction through the inner drive rod 7. Then, the two moving sleeves 8 drive the inner threaded block 23 to slide in the opposite direction along the threaded groove 22, so that the two moving sleeves 8 slide inward synchronously, so that the distance between the two moving sleeves 8 is shortened. Due to the bevel design of the inner wall edge of the moving sleeve 8 and the outer wall of the sliding plate 20, the inner wall of the moving sleeve 8 will gradually press the sliding plate 20 inward, so that the sliding plate 20 drives... One side of the embedded rod 10 slides inward, and the sliding plate 20 compresses the return spring 31 on one side. Then, the embedded rod 10 gradually inserts into the fitting groove 21. Due to the beveled design of one end of the embedded rod 10 and the inner wall edge of the fitting groove 21, when one end of the embedded rod 10 is reinserted into the fitting groove 21, the embedded rod 10, through the beveled structure in the fitting groove 21, drives the insertion tube 5 to slide into the inner side of the connecting tube 4, so that the insertion tube 5 presses the sealing sleeve 25 tightly, ensuring the sealing of the connection. At the same time, multiple sealing rings 27 are provided on the outside of the insertion tube 5 and simultaneously snap into the corresponding fitting grooves 26, forming a multi-layer sealing structure. At this time, the insertion tube 5 is completely engaged with the connecting tube 4. At the same time, the drive frame 6 just drives the action groove 11 to rotate and reset completely. The corresponding action groove 11 rotates to the position corresponding to the original swing rod 13, and then the running sleeve 14 is released. The push spring 28 pushes the running sleeve 14 to drive the guide block 33 to slide and reset along the guide groove 32. The running sleeve 14 will also drive one side of the running rod 15 to slide and reset. Due to the chamfer design of the outer wall of one end of the running sleeve 14 and the rounded corner design of the end of the swing rod 13, one end of the running sleeve 14 will gradually push the corresponding end of the swing rod 13 outward. Then the swing rod 13 will rotate and reset in the action frame 12, so that the other end of the swing rod 13 will be re-engaged into the original action groove 11. At this time, the push spring 28 is fully reset, and the running rod 15 no longer passes through the rotating hole 19. At this time, the configuration spring 18 resets and pushes the configuration block 17, so that the configuration... The placement block 17 drives the configuration rod 29 on one side to reverse and reset along the configuration hole 30. The configuration block 17 also drives the rotation hole 19 to rotate in the opposite direction and reset to a position not corresponding to the operating rod 15 via the rotation plate 16. At this time, the operating rod 15 supports and limits the operating sleeve 14 to one side of the rotation plate 16. Combined with the guide block 33 and guide groove 32 limiting the operating sleeve 14, the operating sleeve 14 cannot move. The operating sleeve 14, together with the swing rod 13, the actuating frame 12, and the actuating groove 11, forms a rotation limit on the drive frame 6, preventing accidental rotation of the drive frame 6. Then, following the above steps, the insertion pipe 5 at the other end of the connecting pipe 24 is connected and fixed, thus preventing accidental loosening or even detachment of the connection structure, thereby ensuring the stability of the pipeline connection.Since the purification device is a mature technology in the existing field, its structure will not be shown in detail, nor will its specific operating principle be described in detail.

[0038] In summary, during the use or operation of the overall equipment: when it is necessary to remove the connecting pipe 24 for maintenance and replacement, first rotate the rotating plate 16 clockwise, causing the rotating plate 16 to drive the configuration block 17 on one side to rotate clockwise. Then, the configuration block 17 will drive the configuration rod 29 on one side to rotate clockwise along the configuration hole 30. The configuration block 17 will cooperate with the mating block 9 to compress the configuration spring 18. At the same time, the rotating plate 16 will drive the rotating hole 19 to rotate clockwise. When the configuration spring 18 is compressed to its limit, the rotating hole 19 will just rotate to a position concentric with the running rod 15, and then push the running sleeve. 14. This causes the running sleeve 14 to slide along the guide groove 32, and the running sleeve 14 will cause the running rod 15 on one side to gradually slide into the rotating hole 19. At the same time, the running sleeve 14 will cooperate with the rotating plate 16 to squeeze the push spring 28, and the running sleeve 14 will gradually stop limiting one end of the swing rod 13. Then the drive frame 6 will rotate in the forward direction, and the drive frame 6 will drive the multiple action grooves 11 opened on one side to rotate. Then the inner wall of the action groove 11 will squeeze one end of the swing rod 13. Due to the rounded corners of the inner wall of the action groove 11 and the end of the swing rod 13, The design involves the rotational connection between the swing rod 13 and the action frame 12. The action groove 11 then pushes one end of the swing rod 13 out, causing it to rotate within the action frame 12 and the other end to rotate inwards. Simultaneously, the drive frame 6 drives the drive rod 7 to rotate forward, causing the drive rod 7 to drive the two moving sleeves 8 to rotate synchronously in the same direction. The moving sleeves 8 then drive the inner threaded block 23 to slide along the threaded groove 22. Since the two threaded grooves 22 are designed to face each other, the two moving sleeves 8 synchronously drive the inner threaded block 23 along... The drive rod 7 slides to both sides, which lengthens the distance between the two moving sleeves 8. Then, the inner wall of the moving sleeve 8 gradually stops limiting the outer wall of the sliding plate 20. Then, the return spring 31 returns to its original position and pushes the sliding plate 20, which causes the sliding plate 20 to drive the one-sided embedded rod 10 to slide outward. This causes one end of the embedded rod 10 to gradually slide out of the fitting groove 21. Then, the insertion tube 5 is pulled to one side to remove the insertion tube 5. Then, the insertion tube 5 at the other end of the connecting tube 24 is removed by referring to the above steps. Then, the connecting tube 24 can be removed for maintenance and replacement.

[0039] When the connecting pipe 24 needs to be reconnected, first insert the plug 5 connected to one end of the connecting pipe 24 into the connecting pipe 4, so that the plug 5 abuts against the sealing sleeve 25. Then, rotate the drive frame 6 in the opposite direction, so that the drive frame 6 drives the multiple action slots 11 opened on one side to rotate in the opposite direction. At the same time, the drive frame 6 drives the two moving sleeves 8 to rotate in the opposite direction through the inner drive rod 7. Then, the two moving sleeves 8 drive the inner threaded block 23 to slide in the opposite direction along the threaded groove 22, so that the two moving sleeves 8 slide inward synchronously, so that the distance between the two moving sleeves 8 is shortened. Due to the bevel design of the inner wall edge of the moving sleeve 8 and the outer wall of the sliding plate 20, the inner wall of the moving sleeve 8 will gradually press the sliding plate 20 inward, so that the sliding plate 20 drives one side to embed. The rod 10 slides inward, and the sliding plate 20 compresses the return spring 31 on one side. Then, the embedded rod 10 gradually inserts into the fitting groove 21. Due to the beveled design of one end of the embedded rod 10 and the inner wall edge of the fitting groove 21, when one end of the embedded rod 10 is reinserted into the fitting groove 21, the embedded rod 10, through the beveled structure in the fitting groove 21, drives the insertion tube 5 to slide into the inner side of the connecting tube 4, so that the insertion tube 5 presses the sealing sleeve 25 tightly, ensuring the sealing of the connection. At the same time, multiple sealing rings 27 are provided on the outside of the insertion tube 5 and simultaneously snap into the corresponding fitting grooves 26, forming a multi-layer sealing structure. At this time, the insertion tube 5 is completely engaged with the connecting tube 4. At the same time, the drive frame 6 just drives the action groove 11 to rotate and reset completely. The operating groove 11 rotates to the position corresponding to the original swing rod 13, and then the operating sleeve 14 is released. The push spring 28 pushes the operating sleeve 14 to drive the guide block 33 to slide and reset along the guide groove 32. The operating sleeve 14 will also drive one side of the operating rod 15 to slide and reset. Due to the chamfer design of the outer wall of one end of the operating sleeve 14 and the rounded corner design of the end of the swing rod 13, one end of the operating sleeve 14 will gradually push the corresponding end of the swing rod 13 outward. Then the swing rod 13 will rotate and reset in the reverse direction in the action frame 12, so that the other end of the swing rod 13 is re-engaged into the original operating groove 11. At this time, the push spring 28 is fully reset, and the operating rod 15 no longer passes through the rotating hole 19. At this time, the configuration spring 18 resets and pushes the configuration block 17, so that the configuration block... 17 drives the configuration rod 29 on one side to reverse and reset along the configuration hole 30. The configuration block 17 also drives the rotation hole 19 to rotate in the opposite direction and reset to a position not corresponding to the operating rod 15 via the rotating plate 16. At this time, the operating rod 15 supports and limits the operating sleeve 14 to one side of the rotating plate 16. Combined with the guide block 33 and guide groove 32 limiting the operating sleeve 14, the operating sleeve 14 cannot move. The operating sleeve 14, together with the swing rod 13, the actuating frame 12, and the actuating groove 11, forms a rotation limit on the drive frame 6, preventing accidental rotation of the drive frame 6. Then, following the above steps, the insertion pipe 5 at the other end of the connecting pipe 24 is connected and fixed, thus preventing accidental loosening or even detachment of the connection structure, thereby ensuring the stability of the pipeline connection.Since the purification device is a mature technology in the existing field, its structure will not be shown in detail, nor will its specific operating principle be described in detail.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
