Description

Technical Field

[0001] The utility model relates to the technical field of adsorption towers for carbon dioxide production, and more specifically, it relates to an adsorption tower for carbon dioxide production. Background Technique

[0002] In the existing carbon dioxide production technology, there are some deficiencies in the design of the spraying device inside the adsorption tower. First of all, the spraying devices of many adsorption towers adopt a simple pipeline structure, which limits the flexibility of adjusting the input speed of the spraying device. In the actual production process, according to different production requirements and working conditions, it is necessary to adjust the spraying speed of the spraying device to optimize the adsorption efficiency. However, due to the inability to flexibly adjust the spraying speed of the existing device, the production process cannot reach the optimal state, affecting the production efficiency of carbon dioxide and the product quality.

[0003] Secondly, in the existing technology when transporting gases, it involves the connection operation between pipelines. This process is usually too cumbersome. In the carbon dioxide production process, the stability and sealing performance of pipeline connections are crucial. However, in the existing technology, the connection operation between pipelines is complex, prolonging the installation and maintenance time and slowing down the production efficiency.

Such a simple connection structure may weaken the sealing effect at the pipeline connection, resulting in gas leakage or entry of external impurities, affecting the stability of the production process and the product quality.

The fixing plate 11 is fixedly connected to the outside of the adjusting pipe 2. Both ends of the elastic sheet 12 are respectively connected with the movable frame 7 and the sliding frame 3. The guiding plate 13 is rotatably arranged outside the adjusting pipe 2. The control sleeve 14 is movably arranged on one side of the adjusting pipe 2. The movable block 15 is fixedly connected to one side of the guiding plate 13. The fixing block 17 is fixedly connected to the outside of the adjusting pipe 2. Both ends of the second tension spring 16 are respectively connected with the fixing block 17 and the movable block 15. On the other side of the adsorption tower 1, there is a connecting pipe 18. Inside the connecting pipe 18, there is an input pipe 19. A sealing mechanism is arranged outside the input pipe 19. A clamping device is arranged outside the input pipe 19. The clamping device includes a guiding groove 20, a clamping mechanism, a matching sleeve 21 and a guiding block 22. The guiding groove 20 is opened on the outside of the matching sleeve 21. The matching sleeve 21 is movably sleeved on the outside of the connecting pipe 18. The guiding block 22 is slidably installed in the guiding groove 20.

[0033] On one side of the adsorption tower 1, there is a storage tank 23. On one side of the storage tank 23, there is a delivery pump 24. Both the input end and the output end of the delivery pump 24 are provided with delivery pipes 25.

[0034] A sliding groove 26 is opened inside the adjusting pipe 2. A sliding block 27 is arranged outside the sliding frame 3. The sliding block 27 is slidably installed in the sliding groove 26.

[0035] On one side of the connecting frame 8, there is a threaded rod 28. On one side of the sliding frame 3, there is a threaded sleeve 29. The threaded sleeve 29 is movably connected to the threaded rod 28 by threads.

[0036] The clamping mechanism includes a matching frame 30 and a matching groove 31. The matching groove 31 is opened on the outside of the input pipe 19. One end of the matching frame 30 is clamped into the matching groove 31. Both sides of the matching frame 30 are connected with the guiding block 22.

[0037] A motor 32 is provided outside the adjusting pipe 2, and a lead screw 33 is provided outside the connecting pipe 18. Opposite threads are symmetrically arranged at both ends of the lead screw 33. The matching sleeve 21 is movably connected to the lead screw 33 through threads. A small gear 34 is provided at the output end of the motor 32 and one end of the lead screw 33. A large gear 35 is movably provided outside the connecting pipe 18, and the large gear 35 meshes with the small gear 34.

[0038] In this embodiment, when the device needs to be used, first, the gas is transported to the adsorption tower 1 through the input pipe 19 and the connecting pipe 18. Then, the spraying liquid stored in the storage tank 23 is pumped out by the delivery pump 24. Then, the pumped spraying liquid is transported to the spraying assembly arranged inside the adsorption tower 1 through the delivery pipe 25 connected to the output end of the delivery pump 24. Then, the spraying liquid is sprayed out through the spraying assembly, so that the spraying liquid and the gas are in full contact. When the spraying flow rate needs to be adjusted, first, the guide plate 13 is rotated in the corresponding direction. The guide plate 13 drives the movable block 15 arranged on one side to move. The movable block 15 and the fixed block 17 cooperate to stretch the second tension spring 16 arranged in the middle. Due to the special structural design of the guide plate 13, when the guide plate 13 rotates, it will push the sliding rod 4 to slide along the limiting groove 9 and the straight groove 10. At the same time, the sliding rod 4 will drive the first tension spring 5 connected to one side to be stretched. When the guide plate 13 cannot rotate, the sliding rod 4 will slide from the limiting groove 9 into the annular groove 6. Then, the control sleeve 14 is rotated. The control sleeve 14 will drive the connecting frame 8 arranged inside to rotate. Then, the connecting frame 8 will drive the threaded rod 28 arranged on one side to rotate. Since the threaded sleeve 29 is movably sleeved outside the threaded rod 28 through threads, and the sliding block 27 and the sliding groove 26 limit the sliding frame 3, then the threaded sleeve 29 will drive the sliding frame 3 to slide along the screw rod. At the same time, the sliding frame 3 will drive the sliding block 27 to slide along the sliding groove 26. Then, the distance between the sliding frame 3 and the movable frame 7 will change, so that the gap of the elastic sheet 12 changes, thereby restricting the flow rate of the gas passing through. After adjusting to the appropriate flow rate, the guide plate 13 is released. The second tension spring 16 will pull the movable block 15 to reset, thereby driving the guide plate 13 to reset. Then, the sliding rod 4 loses the limit of the guide plate 13. The first tension spring 5 drives the sliding rod 4 to reset, so that the sliding rod 4 slides along the straight groove 10 and makes the sliding rod 4 slide from the annular groove 6 into the corresponding limiting groove 9, effectively preventing the control sleeve 14 from rotating unnecessarily by itself.

[0039] Please refer to Figures 1-4 , as an implementation manner of the sealing mechanism: The sealing mechanism includes a sealing ring 36 and a sealing groove 37. The sealing ring 36 is fixedly connected to the outside of the input pipe 19. The sealing groove 37 is opened on the inner side of the connecting pipe 18, and the sealing ring 36 is adapted to the sealing groove 37. A clamping device is arranged on the outside of the input pipe 19.

[0040] The mating groove 31 is provided with a slope 38, and a washer 39 is provided on the outer side of the input pipe 19. The washer 39 is detachably installed in the connecting pipe 18.

[0041] More specifically, when the pipes need to be connected, first turn on the motor 32. The motor 32 drives the small gear 34 connected to the output end to rotate. Then the small gear 34 drives the large gear 35 sleeved on the outer side of the connecting pipe 18 to rotate. Then the large gear 35 drives other small gears 34 to rotate, thereby driving the lead screw 33 to rotate synchronously. Since opposite threads are provided at both ends of the lead screw 33, the mating sleeves 21 on both sides will move synchronously inward. Due to the special mating structure of the guide groove 20 and the guide block 22, when the guide groove 20 moves with the mating sleeve 21, the guide block 22 will drive the mating frame 30 to move outward. When the mating sleeve 21 cannot move, turn off the motor 32. At this time, one end of the mating frame 30 is flush with the inner wall of the connecting pipe 18. Then insert the input pipe 19 into the connecting pipe 18 and make one end of the input pipe 19 abut against the washer 39 provided on the inner side of the connecting pipe 18. Then reverse the motor 32. The motor 32 drives the lead screw 33 to rotate in the reverse direction through the cooperation of multiple small gears 34 and large gears 35, so that the mating sleeve 21 drives the guide groove 20 to reset. Then the guide block 22 will slide along the guide groove 20, and then the mating frame 30 will move inward following the guide block 22. Then the mating frame 30 will be inserted into the mating groove 31. Since the mating groove 31 is provided with a slope 38 with a unique structure, when the mating frame 30 is completely inserted into the mating groove 31, the mating frame 30 will drive the input pipe 19 to press the washer 39 through the mating groove 31 and the slope 38, ensuring the sealing performance between the connecting pipe 18 and the input pipe 19. At the same time, multiple sealing rings 36 provided on the outer side of the input pipe 19 will be correspondingly engaged into the corresponding sealing grooves 37, thereby further strengthening the sealing performance of the connection and preventing gas leakage.

[0042] In summary, when the overall device is in use or operation: when the device needs to be used, first, the gas is transported to the adsorption tower 1 through the input pipe 19 and the connecting pipe 18. Then, the spraying liquid stored in the storage tank 23 is pumped out by the transport pump 24. Then, the pumped spraying liquid is transported to the spraying assembly arranged in the adsorption tower 1 through the transport pipe 25 connected to the output end of the transport pump 24. Then, the spraying liquid is sprayed out through the spraying assembly, so that the spraying liquid and the gas are in full contact. When the spraying flow rate needs to be adjusted, first, rotate the guide plate 13 in the corresponding direction. The guide plate 13 drives the movable block 15 arranged on one side to move. The movable block 15 and the fixed block 17 cooperate to stretch the second tension spring 16 arranged in the middle. Due to the special structural design of the guide plate 13, when the guide plate 13 rotates, it will push the sliding rod 4 to slide along the limit groove 9 and the straight groove 10. At the same time, the sliding rod 4 will drive the first tension spring 5 connected to one side to be stretched. When the guide plate 13 cannot rotate, the sliding rod 4 will slide from the limit groove 9 into the annular groove 6. Then, rotate the control sleeve 14. The control sleeve 14 will drive the connecting frame 8 arranged on the inner side to rotate. Then, the connecting frame 8 will drive the threaded rod 28 arranged on one side to rotate. Since the threaded sleeve 29 is movably sleeved on the outer side of the threaded rod 28 through threads, and the sliding block 27 and the sliding groove 26 limit the sliding frame 3, then the threaded sleeve 29 will drive the sliding frame 3 to slide along the screw rod. At the same time, the sliding frame 3 will drive the sliding block 27 to slide along the sliding groove 26. Then, the distance between the sliding frame 3 and the movable frame 7 will change, so that the gap of the elastic piece 12 changes, thereby restricting the flow rate of the gas passing through. After adjusting to the appropriate flow rate, release the guide plate 13. The second tension spring 16 will pull the movable block 15 to reset, thereby driving the guide plate 13 to reset. Then, the sliding rod 4 loses the limit of the guide plate 13. The first tension spring 5 drives the sliding rod 4 to reset, so that the sliding rod 4 slides along the straight groove 10 and makes the sliding rod 4 slide from the annular groove 6 into the corresponding limit groove 9, effectively preventing the control sleeve 14 from rotating unnecessarily by itself.

[0043] When the pipeline needs to be connected, first turn on the motor 32. The motor 32 drives the small gear 34 connected to the output end to rotate. Then, the small gear 34 drives the large gear 35 sleeved outside the connecting pipe 18 to rotate. Then, the large gear 35 drives other small gears 34 to rotate, thereby driving the lead screw 33 to rotate synchronously. Since opposite threads are provided at both ends of the lead screw 33, the mating sleeves 21 on both sides will move synchronously inward. Due to the special mating structure of the guide groove 20 and the guide block 22, when the guide groove 20 moves along with the mating sleeve 21, the guide block 22 will drive the mating frame 30 to move outward. When the mating sleeve 21 cannot move, turn off the motor 32. At this time, one end of the mating frame 30 is flush with the inner wall of the connecting pipe 18. Then, insert the input pipe 19 into the connecting pipe 18 and make one end of the input pipe 19 abut against the gasket 39 provided inside the connecting pipe 18. Then, reverse the motor 32. The motor 32 drives the lead screw 33 to rotate in the reverse direction through the cooperation of multiple small gears 34 and large gears 35, so that the mating sleeve 21 drives the guide groove 20 to reset. Then, the guide block 22 will slide along the guide groove 20, and then the mating frame 30 will move inward along with the guide block 22. Then, the mating frame 30 will be inserted into the mating groove 31. Since a slope 38 with a unique structure is provided in the mating groove 31, when the mating frame 30 is completely inserted into the mating groove 31, the mating frame 30 will drive the input pipe 19 to press the gasket 39 through the mating groove 31 and the slope 38, ensuring the sealing performance between the connecting pipe 18 and the input pipe 19. At the same time, multiple sealing rings 36 provided outside the input pipe 19 will be correspondingly engaged into the corresponding sealing grooves 37, thereby further enhancing the sealing performance at the connection and preventing gas leakage.

[0044] In all the above-mentioned solutions, for the connection between two components, welding, the cooperation of bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For all the cases of fixed connection mentioned above, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
