Description

Technical Field

[0001] The present invention relates to the technical field of dryers, and specifically relates to a zero-air-consumption compression heat regeneration adsorption dryer. Background Technique

[0002] The adsorption dryer applies advanced chemical technology. Its principle is to use the difference in the volume of water molecules and air molecules in saturated compressed air, and use special molecular sieves for gas purification to filter out saturated water vapor in the compressed air. Chinese Patent with the publication number "CN116726676A" provides an adsorption dryer. This application controls the lateral movement of the sleeve to switch the flow state of the two upper pipes. When the hole slots on one of the sliding connecting pipes are aligned and communicated with the second horizontal pipe, the hole slots on the other sliding connecting pipe are aligned and communicated with the first horizontal pipe. By controlling the lateral movement of the slider, the working procedures of the drying and regeneration stages of the two tanks can be adjusted, thereby effectively controlling the operation of the equipment. However, the gas in the regeneration stage of this application always moves from top to bottom, and the actual drying time of the desiccant at the lower part is short, the drying is not thorough, or the passing time of the regeneration gas is lengthened, resulting in large losses and low overall efficiency.

Specific embodiments

[0028] In order to enable those skilled in the art of the present technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0029] Please refer to Figures 1 to 6 , the present invention provides a zero-air-consumption compression heat regeneration adsorption dryer, including two tank bodies 1. The upper ends of the two tank bodies 1 are connected through a first pipeline 2, and the lower ends of the two tank bodies 1 are connected through a second pipeline 3. The first pipeline 2 is connected to a compressor through a connecting pipe. A switching mechanism 4 is fixedly connected to the center of each tank body 1. The switching mechanism 4 is used to switch the flow direction of air in the tank body 1. A sealing mechanism 5 is rotatably connected to the inner wall of one end of each tank body 1.

[0030] Corresponding valves are provided on both the first pipeline 2 and the second pipeline 3. The high-temperature air discharged from the compressor enters the inside of the tank body 1 through the connecting pipe, enabling the high-temperature air to regenerate the desiccant inside the tank body 1. The direction of the high-temperature air entering the tank body 1 is changed through the provided switching mechanism 4, and the flow direction of the high-temperature air circulates and switches between flowing from top to bottom and from bottom to top, avoiding the high-temperature air always moving from top to bottom, resulting in a relatively short actual drying time for the desiccant at the lower part, incomplete drying, and affecting the drying effect of the wet air in the drying stage. The high-temperature air stays inside the tank body 1 for a longer time through the cooperation of the provided blocking mechanism 5 and the switching mechanism 4, keeping a relatively high temperature inside the tank body 1, enabling the moisture in the desiccant to be better carried out of the tank body 1 by the high-temperature air, and improving the drying effect.

[0031] Please refer to Figure 2 、 Figure 3 and Figure 6 , the switching mechanism 4 includes an outer sleeve 6 fixedly connected inside the tank body 1. A central tube 7 is fixedly connected to the inner wall of the outer sleeve 6 through a fixing frame. A communication groove 18 communicating with the inner cavity of the tank body 1 is opened on the outer sleeve 6. A partition plate 27 is fixedly connected to the inner wall of the outer sleeve 6 at a position below the communication groove 18. The other end of the partition plate 27 is connected to the outer wall of the central tube 7. A fixing seat 8 is fixedly connected to the lower end of the outer sleeve 6. An installation groove 9 is opened on the fixing seat 8. A circulation port 10 is opened at the lower end of the fixing seat 8, and the circulation port 10 communicates with the installation groove 9. A first switching component 28 for blocking the upper and lower ends of the central tube 7 is provided at a position of the central tube 7 below the partition plate 27. A second switching component 29 is provided in the installation groove 9. The first switching component 28 and the second switching component 29 have the same structure. A partition block 16 for controlling the communication between the installation groove 9 and the circulation port 10 is fixedly connected to the second switching component 29. An exhaust pipe 30 is fixedly connected through the partition plate 27, and the other end of the exhaust pipe 30 is connected to the second pipeline 3. A first connecting rod 31 is fixedly connected to the first switching component 28. A first gear ring 32 is fixedly connected to the first connecting rod 31. The first gear ring 32 is connected to a second gear ring 33 through a gear. Both the first gear ring 32 and the second gear ring 33 are sleeved and rotatably connected to the outer wall of the central tube 7. A second connecting rod 34 is fixedly connected to the second gear ring 33, and the second connecting rod 34 is fixedly connected to the second switching component 29.

[0032] The opening and closing states of the first switching component 28 and the second switching component 29 are opposite. When switching, the second switching component 29 drives the second connecting rod 34 to rotate. The rotation of the second connecting rod 34 drives the second gear ring 33 to rotate. The rotation of the second gear ring 33 drives the first gear ring 32 to rotate through the gear. The rotation of the first gear ring 32 drives the first switching component 28 to rotate, realizing the switching between the two states. When the second switching component 29 does not block the central pipe 7, it drives the partition block 16 to move to block the installation groove 9 and the communication port 10, preventing high-temperature air from entering the tank body 1. In the initial state, the first switching component 28 blocks the central pipe 7, and the second switching component 29 does not block the lower end of the central pipe 7. The blocking mechanism 5 does not block the position between the outer sleeve 6 and the central pipe 7. High-temperature air flows into the outer sleeve 6 and enters the interior of the tank body 1 through the communication groove 18. The high-temperature air dries the desiccant and brings moisture into the communication port 10 through the through hole 36. Then it enters the installation groove 9 and is discharged through the second switching component 29 into the second pipeline 3. In the next regeneration stage, the second switching component 29 blocks the lower end of the central pipe 7, the first switching component 28 does not block the central pipe 7, and the blocking mechanism 5 blocks the position between the outer sleeve 6 and the central pipe 7. High-temperature air enters the central pipe 7 and flows into the installation groove 9. Then it enters the tank body 1 through the communication port 10 and the through hole 36, and enters the space between the outer sleeve 6 and the central pipe 7 through the communication groove 18. Then it flows into the second pipeline 3 through the exhaust pipe 30 and is discharged. The high-temperature air flows in the tank body 1, the outer sleeve 6 and the central pipe 7. The high-temperature air stays in the internal space of the tank body 1 for a relatively long time, keeping the overall temperature inside the tank body 1 relatively high, facilitating the discharge of moisture from the desiccant, and thus improving the drying effect of the next batch of wet air. At the same time, the flow direction of the high-temperature air cycles between from top to bottom and from bottom to top, preventing the high-temperature air from always moving from top to bottom, resulting in a shorter actual drying time for the desiccant at the lower part and incomplete drying, which affects the drying effect of the wet air during the drying stage.

[0033] Please refer to Figure 6 , the second switching component 29 includes a rotating disk 11 rotatably connected in the installation groove 9. The rotating disk 11 is provided with inclined grooves 12 in an array. Each inclined groove 12 is slidably connected with a sliding block 13. A partition piece 14 is fixedly connected to the sliding block 13. A rotating shaft 15 is fixedly connected to the position of the partition piece 14 away from the sliding block 13. The rotating shaft 15 is rotatably connected with the rotating disk 11.

[0034] When the rotating disk 11 rotates, it drives the sliding block 13 to slide. The movement of the sliding block 13 drives the partition piece 14 to rotate around the rotating shaft 15, so that the partition piece 14 blocks the central pipe 7. When the rotating disk 11 rotates in the reverse direction, the partition piece 14 does not block the central pipe 7.

[0035] Please refer toFigure 4 and Figure 6 , the plugging mechanism 5 includes plugging pieces 19 rotatably connected in an array to the inner wall of the outer sleeve 6. A first sliding groove 20 is formed on one side of each plugging piece 19. A sliding piece 21 is fixedly connected to the side of each plugging piece 19 away from the first sliding groove 20. The sliding piece 21 is located in the first sliding groove 20 of the adjacent plugging piece 19. A second sliding groove 22 is formed on the inner wall of the outer sleeve 6 close to the plugging piece 19. A sliding rod 23 is slidably connected in the second sliding groove 22. A threaded rod 24 is sleeved and threadedly connected through the sliding rod 23. One end of the threaded rod 24 away from the sliding rod 23 is fixedly connected to a connecting rod 37. A rotating rod 17 is fixedly connected to the connecting rod 37. The rotating rod 17 is slidably connected to the rotating disk 11 through a limiting groove. The sliding rod 23 abuts against the plugging piece 19.

[0036] When the rotating disk 11 rotates, it drives the rotating rod 17 to rotate around the threaded rod 24. The rotation of the rotating rod 17 drives the connecting rod 37 to rotate. The rotation of the connecting rod 37 drives the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the sliding rod 23 to move. The movement of the sliding rod 23 drives the plugging piece 19 to rotate, thereby plugging the space between the outer sleeve 6 and the central tube 7. When the rotating disk 11 rotates in the reverse direction, the plugging piece 19 returns to the initial position by its own weight and the elastic cord 26. The sliding piece 21 is located in the first sliding groove 20 of the adjacent plugging piece 19, enabling the sliding piece 21 to contract, and achieving the state of plugging or opening the space between the outer sleeve 6 and the central tube 7.

[0037] Please refer to Figure 6 , one end of the plugging piece 19 away from the outer sleeve 6 is arc-shaped. One end of the plugging piece 19 away from the outer sleeve 6 fits with the central tube 7 to plug the space between the outer sleeve 6 and the central tube 7, preventing high-temperature air from passing through there.

[0038] Please refer to Figure 4 , one end of the plugging piece 19 close to the inner wall of the outer sleeve 6 is fixedly connected to an elastic cord 26. The other end of the elastic cord 26 is fixedly connected to the inner wall of the outer sleeve 6. The elastic cord 26 facilitates the return of the plugging piece 19 to the initial position.

[0039] Please refer to Figure 6 , the partition blocks 16 are connected end to end with the adjacent partition blocks 16, thereby partitioning the installation groove 9 and the flow-through port 10.

[0040] Please refer to Figure 6 , the second connecting rod 34 is fixedly connected to the rotating disk 11 in the second switching assembly 29. The first connecting rod 31 is fixedly connected to the rotating disk 11 in the first switching assembly 28. When the rotating disk 11 in the second switching assembly 29 rotates, it drives the rotating disk 11 in the first switching assembly 28 to rotate through a transmission structure.

[0041] Please refer to Figure 3 , a hydraulic rod 35 is hinged on the fixed seat 8, and the output end of the hydraulic rod 35 is hinged to the rotating disc 11, and the rotating disc 11 is driven to rotate by the hydraulic rod 35.

[0042] Please refer to Figure 3 , through holes 36 are arrayed and opened at a position of the outer sleeve 6 close to the partition piece 14, and the through holes 36 are communicated with the circulation ports 10, so that high-temperature air enters the tank body 1 through the through holes 36.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
