Abstract
Description
Technical Field
[0001] This invention belongs to the field of air drying technology, specifically relating to a refrigerated compressed air dryer. Background Technology
[0002] A refrigerated dryer is a compressed gas purification device that utilizes the principle of refrigeration. It cools compressed gas containing a large amount of saturated water vapor from upstream pipelines, condensing most of the water vapor into liquid water droplets. These droplets are then removed through gas-water separation, resulting in dry air. The condensate separated during the water vapor separation process is discharged through an automatic drainer. It is primarily used in industrial manufacturing, electronics, and chemical industries.
[0003] A refrigerated air dryer, short for a freeze dryer, is an air source processing component in a pneumatic system. It mainly consists of four parts: a refrigeration compressor, a condenser, an evaporator, and an expansion valve. It works on the principle of cooling and condensation. Compressed air first enters a precooler to remove some of its heat energy, then enters a hot and cold air exchanger to exchange heat with the cold air that has been cooled to its pressure dew point after exiting the evaporator, further reducing the temperature of the compressed air. After that, the compressed air enters the evaporator to exchange heat with the refrigerant, and the temperature of the compressed air drops to 0-8°C. At this temperature, the moisture in the air precipitates out and is separated by an air-water separator before being discharged through an automatic drain valve. The dry, low-temperature air then enters the hot and cold air exchanger for heat exchange, and is output after its temperature rises.
[0004] After water vapor separation in compressed air, the separated condensate is discharged through an automatic drain. Since the condensate contains a certain amount of impurities, it can clog the automatic drain, affecting the drainage and causing abnormal operation of the refrigerated compressed air dryer. In the existing technology, a filter screen is installed in the automatic drain screen, which can filter the condensate. However, the filtered impurities accumulate on the filter screen, causing blockage and affecting the drainage of condensate. Furthermore, stopping the machine to clean the filter screen will affect the working effect of the dryer, thus affecting the operation of the refrigerated compressed air dryer.
[0005] Therefore, the present invention provides a refrigerated compressed air dryer. Summary of the Invention

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 10 As shown, the present invention provides a technical solution: a refrigerated compressed air dryer, comprising a dryer body 1, a compression mechanism 2 fixedly installed inside the dryer body 1, a condensation mechanism 3 fixedly connected to one side of the compression mechanism 2, a water vapor separation mechanism 4 fixedly connected to one side of the condensation mechanism 3, a hot and cold air exchanger 5 fixedly connected above the water vapor separation mechanism 4, an exhaust pipe 7 fixedly connected above the hot and cold air exchanger 5, and an air inlet pipe 6 fixedly connected to one side of the compression mechanism 2. The condensation mechanism 3, the water vapor separation mechanism 4, and the hot and cold air exchanger 5 are all fixedly installed inside the dryer body 1, and the water vapor separation... A water pumping pipe 8 is fixedly connected to one side of the mechanism 4. A processing box 9 is fixedly installed inside the dryer body 1. The water pumping pipe 8 is fixedly connected to the top of the processing box 9. Filter plates 10 are symmetrically fixedly installed inside the processing box 9. A flow guiding component for adjusting the flow direction of condensate is provided above the filter plates 10. A scraping component is provided on the upper surface of the filter plates 10. The scraping component includes two movable scrapers 11. The bottom of the scrapers 11 is respectively attached to the upper surface of the filter plates 10. A material collection and return component is provided on both sides of the processing box 9 to collect impurities and return residual condensate.
[0025] During operation: The air requiring drying is first introduced into the compression mechanism 2 through the intake pipe 6 for compression, then sequentially enters the condensation mechanism 3 for cooling and condensation, the water vapor separation mechanism 4 to remove liquid water, and the hot and cold air exchanger 5 for heat exchange, finally being discharged through the exhaust pipe 7. The condensate separated by the water vapor separation mechanism 4 enters the processing chamber 9 through the water suction pipe 8 for filtration to remove impurities and prevent pollution and pipe blockage during subsequent discharge or recycling. Initially, under the action of the diversion component, the condensate entering from the top of the processing chamber 9 first flows towards... Above the right-side filter plate 10, the left-side filter plate 10 is currently in standby mode. As the right-side filter plate 10 continuously filters the condensate, impurities gradually accumulate on its upper surface, effectively intercepting and removing impurities from the condensate. However, after a period of use, excessive impurity accumulation on the right-side filter plate 10 can affect its filtration effect, leading to a decrease in filtration efficiency. At this point, the flow diversion component is activated to adjust the flow direction of the condensate, redirecting the condensate entering from the top of the treatment chamber 9 to flow above the left-side filter plate 10, ensuring uninterrupted filtration. The movement of the flow diversion component further promotes the flow of condensate. During the process of moving the material upwards from the left filter plate 10, the scraper 11 located above the right filter plate 10 moves along its surface via the scraper assembly. As the scraper 11 moves, it pushes the impurities accumulated on the surface of the right filter plate 10 to the outside of the processing chamber 9. Ultimately, the impurities above the right filter plate 10 are pushed into the right-side collection and return assembly. This assembly not only collects the impurities but also further separates the residual condensate from them. The separated residual condensate is then returned to the condensate filtered by the filter plate 10. Similarly, when the left filter plate 10 filters… After a period of time, the accumulation of impurities will also affect the filtration effect. At this time, the diversion component is restarted to redirect the condensate back to the right filter plate 10, ensuring uninterrupted filtration. While the diversion component is in operation, the scraping component moves the scraper 11 on the left side, pushing the impurities on the surface of the left filter plate 10 into the left collection and return component. This component collects the impurities and separates the residual condensate, which is then returned to the filtered condensate. In this way, the left and right filter plates 10 are used alternately to achieve continuous filtration of condensate, automatic impurity removal, and residual water recovery, thereby extending the service life of the filter plates and improving the treatment efficiency. Through the above embodiments, the flow direction of condensate inside the treatment chamber 9 is adjusted by the diversion component, allowing condensate entering from the top to selectively flow to the left or right filter plates 10. This prevents a decrease in filtration efficiency due to excessive accumulation of impurities on one side of the filter plate, enabling alternating use of the left and right filter plates 10 and ensuring continuous filtration. The scraping component, while the diversion component switches the condensate flow direction, moves the bottom of the corresponding scraper 11 along the surface of the filter plate 10, achieving synchronized and coordinated cleaning and filtration. The scraper 11 cleans the impurities accumulated on the upper surface of the filter plate 10 and pushes the impurities outwards from the treatment chamber 9, preventing the impurities from accumulating. The material falls into the filtered condensate, thus ensuring the cleanliness of the filter plate surface and the stability of the filtration effect. The scraping action is completed automatically during the filtration switching process, without affecting the normal filtration process of the condensate, restoring the effective filtration area of the filter plate surface, and maintaining the continuity and consistency of the filtration effect. The material collection and return component is used to receive and collect the impurities pushed into the surface of the filter plate 10 by the scraper 11, and further separate the residual condensate carried in the impurities. The separated condensate is returned to the filtered condensate, reducing water waste, improving the condensate recycling rate, and avoiding the direct discharge or recycling of condensate containing impurities, effectively preventing blockage problems caused by impurity deposition in the subsequent pipeline system.
[0026] like Figures 4 to 5 As shown, a partition plate 12 is fixedly connected to the center of the interior of the processing box 9. The partition plate 12 divides the interior of the processing box 9 into processing chamber one 13 and processing chamber two 14. Two filter plates 10 are located inside processing chamber one 13 and processing chamber two 14, respectively.
[0027] During operation: The partition plate 12 divides the interior of the treatment chamber 9 into two independent and symmetrical treatment chambers 13 and 14, so that the two filter plates 10 are located in their respective closed chambers. This prevents condensate or impurities from flowing between the two sides during the filtration process, ensuring that the working environment of each filter plate is independent and controllable. It also prevents impurities from entering the filtered condensate on the other side when cleaning one side. The drainage component selectively guides the condensate to the top of one of the chambers, where the filter plate 10 performs filtration, while the other chamber is in standby or cleaning mode, without interfering with each other, thus ensuring the continuity and stability of the filtration operation.
[0028] like Figures 4 to 6As shown, the drainage assembly includes a rotating shaft 15, which is rotatably connected to the inside of the processing box 9. A servo motor 17 is fixedly installed on the outer wall of the processing box 9. The output shaft of the servo motor 17 is fixedly connected to one end of the rotating shaft 15. A drainage plate 16 is fixedly connected to the outer wall of the rotating shaft 15. The top of the processing box 9 is arc-shaped. The end of the drainage plate 16 away from the rotating shaft 15 is attached to the inner side of the top of the processing box 9. The end of the drainage plate 16 near the rotating shaft 15 is attached to the top of the partition plate 12.
[0029] During operation: In the initial state, the guide plate 16 is tilted above the left filter plate 10. The condensate entering the treatment chamber 9 through the water pipe 8 will flow along the inclined surface of the guide plate 16 to the surface of the right filter plate 10, where it will be filtered. When too many impurities accumulate on the surface of the right filter plate 10, affecting the filtration effect, the servo motor 17 is started. The servo motor 17 drives the rotating shaft 15 to rotate, which in turn drives the guide plate 16 to rotate to the right, tilting it above the right filter plate 10. At this time, the condensate entering from the top of the treatment chamber 9 is redirected by the guide plate 16 to flow to the surface of the left filter plate 10, where it will be filtered. This achieves the switching of the condensate flow direction and the alternating use of the left and right filter plates 10.
[0030] like Figures 5 to 6 As shown, a limiting block 19 is symmetrically fixedly connected to the top of the processing box 9. One side of the limiting block 19 can fit with one side of the diversion plate 16. Both sides of the diversion plate 16 are fixedly connected with arc-shaped baffles 18. The arc-shaped baffles 18 fit with the inner side of the top of the processing box 9, and the arc-shaped baffles 18 are slidably connected to the inner wall of the limiting block 19.
[0031] During operation: When the guide plate 16, which is biased to the left, rotates to the right, the scraper 11 on the right surface moves along the surface of the right filter plate 10 through the scraping assembly, and begins to clean the impurities accumulated on the right filter plate 10. When the guide plate 16 first starts to rotate, it will drive the arc-shaped baffle 18 to move, so that the arc-shaped baffle 18 temporarily blocks the inlet of the water pumping pipe 8 to prevent condensate from continuing to fall during the switching process, and ensure that no more condensate enters the top of the right filter plate 10 at this time, preventing unfiltered condensate from falling directly into the side that has been filtered. The limiting block 19 makes it easy for the guide plate 16 to stop after rotating into place, so that the guide plate 16 stays stably in the preset position, thereby ensuring that the condensate can flow accurately to the target filter plate after switching.
[0032] like Figures 7 to 9As shown, the scraping assembly also includes two shaft brackets 20, which are fixedly connected to one side of the scraper 11. Slider 22s are fixedly connected to both ends of the fixed rod of the shaft bracket 20. Slide rod seats 21 are symmetrically fixedly connected to both sides of the outer side of the processing box 9. The inner wall of the slider 22 is fixedly connected to the slide rod of the slide rod seat 21. The outside of the slider 22 is provided with a swinging component that drives it to move along the slide rod of the slide rod seat 21.
[0033] During operation: When the guide plate 16, which is biased to the left, rotates to the right, it drives the sliders 22 on both sides of the scraper 11 above the right filter plate 10 to slide along the slide rod of the slide rod seat 21 through the swing assembly. The sliders 22 drive the scraper 11 from one end of the filter plate 10 to the other end through the shaft frame 20, so that the bottom of the scraper 11 is in contact with the surface of the filter plate 10 and pushes the accumulated impurities to the outside of the processing box 9, thereby completing the automatic cleaning of the right filter plate 10. Similarly, when the guide plate 16 rotates from the right to the left, it drives the scraper 11 above the left filter plate 10 to move and clean through the swing assembly, realizing the alternating action of the scrapers 11 on the left and right sides.
[0034] like Figures 7 to 9 As shown, the swing assembly includes two bearing seats 25, and a swing rod 24 is fixedly connected to the bottom of each bearing seat 25. The shaft of the bearing seat 25 is rotatably connected to the outer wall of the processing box 9. An external ball 23 is fixedly connected to one side of each slider 22. The external ball 23 is located on both sides of the swing rod 24. A gear 26 is fixedly connected to the outer wall of the shaft of the bearing seat 25. A sector gear 27 is symmetrically fixedly connected to the outer wall of the rotating shaft 15. The teeth of the sector gear 27 can mesh with the teeth of the gear 26.
[0035] During operation: When the servo motor 17 drives the rotating shaft 15 to rotate to the right, the rotating shaft 15 drives the guide plate 16 to rotate to the right. At the same time, the sector gear 27 on the outer wall of the rotating shaft 15 rotates accordingly. The sector gear 27 meshes with the corresponding gear 26, causing the bearing seat 25 and the swing rod 24 on that side to rotate around the axis. During the swinging process, the swing rod 24 pushes the outer ball 23 located on the right side. The slider 22 drives the scraper 11 above the filter plate 10 on the right side to move along the surface of the filter plate through the shaft frame 20, pushing the accumulated impurities to the outside of the processing box 9; when the rotating shaft 15 rotates to the right side, the servo motor 17 drives the guide plate 15 to rotate to the right. When the shaft 15 rotates to the left in the opposite direction, the sector gear 27 and gear 26 mesh again, driving the swing rod 24 to swing to the left, pushing the outer ball 23 and slider 22 on the left, and driving the scraper 11 on the left to move and clean the impurities on the surface of the left filter plate 10; through the meshing transmission of the sector gear 27 and gear 26, the rotational motion of the shaft 15 is converted into the reciprocating swing of the swing rod 24, and then converted into the linear movement of the scraper 11 through the outer ball 23 and slider 22, thereby realizing the switching of the rotation direction of the guide plate 16 and the cleaning action of the corresponding side scraper 11.
[0036] like Figures 8 to 9 As shown, a torsion spring 28 is fixedly connected to one side of the swing rod 24. The side of the torsion spring 28 away from the swing rod 24 is fixedly connected to the outer wall of the processing box 9. A return spring 29 is provided on the outside of the slide rod of the slide rod seat 21. The return spring 29 is fixedly connected to one side of the slider 22 and the inner wall surface of the slide rod seat 21, respectively.
[0037] During operation: When the rotating shaft 15 drives the guide plate 16 to rotate to the right, the rotating shaft 15 drives the sector gear 27 to rotate to the left, and the sector gear 27 drives the gear 26 to rotate to the right. This causes the bearing seat 25 and the swing rod 24 to swing to the right together. The swing rod 24 squeezes the outer ball 23 and the slider 22 on the right side, causing the corresponding scraper 11 above the filter plate 10 on the right side to move along its surface, completing the cleaning of impurities. When the swing rod 24 swings to the right, it stretches the torsion spring 28 and deforms, while the slider 22 moves along the slide rod of the slide rod seat 21. When the device moves, it will compress the return spring 29 and cause it to deform. When the drainage plate 16 rotates to the right, the sector gear 27 and the gear 26 disengage. Under the return force of the torsion spring 28, the swing rod 24 swings back to reset. At the same time, the return spring 29 releases its force, pushing the slider 22 and the scraper 11 to slide back along the slide rod to reset, so that the scraper 11 returns to its initial position and waits for the next cleaning action. Similarly, when the drainage plate 16 swings to the left, the sector gear 27 on the left engages with the gear 26 on the left, driving the scraper 11 on the left to complete the cleaning and reset process.
[0038] like Figure 4 and Figure 10 As shown, the material return assembly includes two collection bins 34, which are fixedly connected to both sides of the processing box 9. Each collection bin 34 has a filter plate 36 fixedly connected to its bottom, and a return bin 37 fixedly connected below each filter plate 36. Each collection bin 34 has a door 40 on one side.
[0039] During operation: When the scraper 11 pushes the impurities on the surface of the filter plate 10 to the outside of the treatment chamber 9, the impurities fall directly into the collection chamber 34 on the corresponding side, achieving centralized collection of impurities; the residual condensate carried by the impurities falling into the collection chamber 34 permeates downward under the action of gravity, and is further filtered and separated by the filter plate 36. The separated clean condensate flows into the return chamber 37 below; the condensate in the return chamber 37 flows back to the filtered condensate collection system through the pipe, realizing the recycling of water resources; while the impurities are trapped in the collection chamber 34 above the filter plate 36. After accumulating to a certain amount, they are centrally cleaned by opening the door 40.
[0040] like Figures 9 to 10As shown, both sides of the processing box 9 are provided with discharge ports 30. The inner walls of the discharge ports 30 are rotatably connected with rotating shafts 32. The outer walls of rotating shafts 32 are fixedly connected with sealing plates 31. A torsion spring 35 is fixedly connected between the sealing plate 31 and the inner top of the collection chamber 34. The outer walls of the fixing rods of the shaft frame 20 are fixedly connected with push blocks 33, which are located on one side of the sealing plate 31.
[0041] During operation: The treatment chamber 9 is connected to the collection chamber 34 through the discharge port 30. In the initial state, the sealing plate 31 is vertical under the elastic force of the second torsion spring 35, blocking the discharge port 30 to prevent the condensate in the treatment chamber 9 from flowing directly into the collection chamber 34 without treatment. When the scraper 11 above the filter plate 10 on the right side moves along its surface, the shaft bracket 20 drives the push block 33 to move synchronously and gradually approach the sealing plate 31. As the scraper 11 continues to move, the push block 33 contacts the sealing plate 31 and pushes the sealing plate 31 around the second shaft 32 to overcome the elastic force of the second torsion spring 35 towards the collection chamber 34. 4. The inner side rotates, thereby opening the discharge port 30; at this time, the scraper 11 pushes the impurities on the surface of the filter plate 10 toward the discharge port 30, and the impurities fall into the collection chamber 34 through the opened discharge port 30; when the scraper 11 finishes cleaning and resets, the push block 33 disengages from the sealing plate 31, and the sealing plate 31 rotates in the opposite direction and resets under the elastic force of the torsion spring 35, and re-enters the vertical state to seal the discharge port 30, restoring the isolation between the processing box 9 and the collection chamber 34; similarly, when the scraper 11 on the left moves, the push block 33 on the left opens the sealing plate 31 on the left, allowing the impurities on the left to enter the collection chamber 34 on the left.
[0042] like Figures 3 to 4 As shown, the bottom of both the first processing chamber 13 and the second processing chamber 14 are fixedly connected to a water collection chamber 38. The water collection chamber 38 is located below the filter plate 10. The bottom of the return chamber 37 is fixedly connected to one side of the water collection chamber 38. An automatic drainer 39 is fixedly installed inside the dryer body 1. The water collection chamber 38 and the automatic drainer 39 are fixedly connected.
[0043] During operation: the clean condensate filtered by filter plate 10 flows downward under gravity and flows into the water collection chamber 38 below the corresponding treatment chamber; at the same time, the residual condensate separated in the material return assembly flows from the bottom of the return chamber 37 into one side of the water collection chamber 38 and merges with the filtered condensate; after the condensate in the water collection chamber 38 reaches a certain level, it enters the automatic drainer 39 through the connecting pipe. The automatic drainer 39 automatically discharges the condensate to the outside of the dryer body 1 or the recovery system according to the change in liquid level.
