Description

Technical Field

[0001] The present invention relates to the technical field of air compressor drying, and particularly to a drying device for an air compressor. Background Art

[0002] The air compressor drying device is a key equipment in the compressed air system, which is used to remove moisture in the compressed air to prevent pipeline corrosion, equipment failure and process quality problems caused by water vapor condensation. The adsorption dryer utilizes the adsorption capacity of the microporous surface of adsorbents (such as activated alumina, silica gel, molecular sieve), and realizes continuous drying through the alternating operation of two towers. The wet air enters the drying tower filled with adsorbent, the moisture is captured by the adsorbent, and the dried air is output. When the wet air of the adsorption dryer enters the drying tower filled with adsorbent, the moisture is captured by the adsorbent and the dried air is output. However, due to the influence of long-term drying treatment work, the adsorbent is prone to adsorption saturation, which in turn affects the drying effect of the air. The existing adsorbent regeneration method is to alternately carry out drying and regeneration work in two drying towers respectively. However, the adsorbent at the bottom of the drying tower is the first to reach adsorption saturation, and the adsorption saturation degree of the adsorbent gradually decreases from bottom to top. Before the existing drying tower regenerates the adsorbent approaching saturation, it usually switches to regeneration when reaching about 80% - 90% saturation. This regeneration method has the problem of affecting the air drying effect. Summary of the Invention

[0024] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0025] Example 1: Please refer to Figures 1 - 16 , a drying device for an air compressor, comprising a frame 1 and two drying towers 2 fixed on the frame 1, and also comprising: an air inlet pipe 3 fixed on the drying tower 2, and a three-way pipe a4 is fixed between the two air inlet pipes 3, an air filter unit 5 is arranged at one end of the three-way pipe a4, the air filter unit 5 is used for filtering the air inlet, and a plurality of equally distributed air-permeable baffles 6 are fixed in the drying tower 2, the drying tower 2 is filled with an adsorbent, a recovery unit 7 is arranged on the drying tower 2, the recovery unit 7 is used for recovering the adsorbent, and; an air outlet pipe 8 fixed on the drying tower 2, and a three-way pipe b9 is fixed between the two air outlet pipes 8, an output pipe 10 is fixed at one end of the three-way pipe b9, a dispersion mechanism 11 is arranged in the drying tower 2, and the dispersion mechanism 11 is used for dispersing and stirring the adsorbent; It should be noted that electromagnetic valves are fixed on both the air inlet pipe 3 and the air outlet pipe 8, and the closing state of the air inlet pipe 3 and the air outlet pipe 8 is controlled by the electromagnetic valves. When air is input by the three-way pipe a4, the electromagnetic valves on the two air inlet pipes 3 are in the closed and open states respectively. When the drying tower 2 is in the adsorption state, the other drying tower 2 enters the regeneration stage, and the air enters from the bottom of the drying tower 2 and is adsorbed by the adsorbent from bottom to top, so that the water molecules in the air can be adsorbed on the surface of the adsorbent until the adsorbent reaches a saturated state. When the adsorbent reaches a saturated state, the adsorbent is extracted and recovered by the recovery unit 7, and the adsorbent is heated by the drying component 25. The saturated adsorbent is heated, and then the kinetic energy of the water molecules is increased, making it easier to separate from the adsorbent surface, and the adsorbent after treatment is re-input into the drying tower 2; It should also be noted that, through the coordinated arrangement of the recovery unit 7, the dispersion mechanism 11 and the blanking piece 54, it is possible to recover and regenerate the saturated adsorbent at the bottom when the drying tower 1 is in the drying process, and complete the purpose of cyclic regeneration, thereby achieving the purpose of regenerating the adsorbent without stopping the machine.

[0026] Further, the recovery unit 7 includes: a drying cylinder 20 is fixed on the drying tower 2 through a bracket 19, and a delivery pump a22 is fixed on the drying tower 2 through a support frame a21. A pipe a23 is fixed and connected between the input end of the delivery pump a22 and the drying tower 2. A pipe b24 is fixed and connected between the output end of the delivery pump a22 and the drying cylinder 20. A drying component 25 is arranged in the drying cylinder 20. The drying component 25 is used for heating and drying the adsorbent to restore the adsorption saturation degree. A delivery pump b27 is fixed on the drying cylinder 20 through a support frame b26. A material pipe a28 is fixed at the input end of the delivery pump b27. The material pipe a28 penetrates and extends into the interior of the drying cylinder 20. A material pipe b29 is fixed and connected between the output end of the delivery pump b27 and the drying tower 2; Among them, the drying component 25 includes: a shaft body a30 rotatably connected to the drying cylinder 20. A servo motor a31 is fixed on the drying cylinder 20. The output shaft of the servo motor a31 is fixed to the shaft body a30. A separation cylinder 32 is fixed at one end of the shaft body a30. A number of drain holes 33 are formed in the separation cylinder 32. A drain pipe 34 is fixed on the drying cylinder 20 and is connected to the interior. A heating pipe 35 is fixed in the drying cylinder 20, and the heating pipe 35 is located directly below the separation cylinder 32; Specifically, air valves are arranged on both the drying cylinder 20 and the drying tower 2. When the delivery pump a22 pumps the adsorbent to the drying tower 2, the air valve on the drying tower 2 is opened to provide air for the delivery pump a22 to pump the adsorbent. And when the delivery pump a22 transports the adsorbent into the drying cylinder 20, the air valve on the drying cylinder 2 is opened to discharge the air in the drying cylinder 20. And when the delivery pump b27 pumps the adsorbent in the drying cylinder 20, the air valve on the drying cylinder 2 is opened again to provide intake air for the delivery pump b27 to pump the adsorbent. When the delivery pump b27 transports the adsorbent into the drying tower 2, the air valve on the drying tower 2 is opened again to discharge the air when the delivery pump b27 transports the adsorbent into the drying tower 2; It should be noted that the adsorbent at the bottom of the drying tower 2 first comes into contact with the air, so that the air is adsorbed and dried by multiple layers of adsorbents in sequence. The adsorbent at the bottom first reaches the adsorption saturation state. The recovery unit 7 extracts the adsorbent in the adsorption saturation state and performs heating and drying treatment, so that the adsorbent can be restored to a state close to the initial state, and the recovery unit 7 transports the adsorbent into the drying tower 2 to re-adsorb and dry the air; It should also be noted that through the setting of the recovery unit 7, the adsorbent that has been saturated with adsorption can be heated quickly and efficiently. This process can not only effectively remove the impurities adsorbed on the surface of the adsorbent, but also restore it to the unsaturated initial state. Subsequently, the treated adsorbent is re-transported into the drying tower 2, and the drying component 25 uses two methods of pressure and heating in cooperation to comprehensively regenerate the adsorbent, which can not only significantly accelerate the regeneration speed of the adsorbent, but also ensure the stability and reliability of the regeneration process. In this way, the rapid and efficient regeneration treatment of the adsorbent is realized, greatly improving the treatment efficiency, and making the entire regeneration process more stable and controllable; The principle of recycling and regenerating the adsorbent in the drying tower 2 using the recycling component and the drying component 25: The adsorbent saturated with adsorption in the drying tower 2 is extracted by the transfer pump a22, and the adsorbent is transported into the drying cylinder 20 through the pipeline b24, and it is ensured that the adsorbent falls into the separation cylinder 32. Driven by the servo motor a31, the rotating shaft a36 rotates synchronously and drives the separation cylinder 32 to rotate at a high speed. While the separation cylinder 32 is rotating, the air in the drying cylinder 20 is heated and dried by the heating pipe 35, thereby achieving the purpose of regenerating the adsorbent saturated with adsorption. The water separated under high-speed rotation is thrown out through the drain hole 33 and discharged externally through the drain pipe 34. The adsorbent in the separation cylinder 32 is extracted through the transfer pump b27 and the material pipe a28, and the regenerated adsorbent is transported into the drying cylinder 20 through the material pipe b29, thus completing the recycling and regeneration of the adsorbent.

[0027] Furthermore, a sealing member 44 is provided on the drying tower 2. The sealing member 44 includes: a guide cover 45 is fixed inside the drying tower 2, and a barrier ring 46 is rotatably connected inside the drying tower 2. The other side of the barrier ring 46 is rotatably connected to the inside of the guide cover 45. A rod body a47 is rotatably connected inside the guide cover 45. A small gear 48 is fixed on the rod body a47. Teeth 49 meshing with the small gear 48 are fixed on the barrier ring 46. A micro motor 50 is fixed on the drying tower 2. One end of the output shaft of the micro motor 50 is coaxially fixed with a rod body b51. The rod body b51 and the rod body a47 are meshed and driven by two bevel gears b52. A channel 53 is opened on the barrier ring 46; Among them, at least two limiting blocks 65 are fixed on the barrier ring 46. The length of the limiting block 65 is greater than the length of the teeth 49. The central axis of the barrier ring 46 is collinear with the central axis of the guide cover 45. By adding the limiting blocks 65, it can be ensured that when the barrier ring 46 rotates 90 degrees, the channel 53 is exactly in a matching state with the port of the pipeline a23; It should be noted that when the drying cylinder 20 is in the adsorption working state, the barrier ring 46 blocks and seals one end of the pipeline a23. In addition, when the drying tower 2 is not in the adsorption working state, the barrier ring 46 rotates to ensure that the channel 53 on the barrier ring 46 is in alignment with the port of the pipeline a23; It should also be noted that through the setting of the sealing member 44, the sealing state of the pipeline a23 can be effectively regulated, avoiding the situation that the adsorbent enters the pipeline a23 during the adsorption work, and the adjustment flexibility of the barrier ring 46 is high and more reliable; The principle of using the closing ring to release the blockage of the pipeline a23 is that through the drive of the micro motor 50, the rod body b51 rotates synchronously. By the meshing transmission of the bevel gear b52, the rod body a47 is driven to rotate synchronously, and then the small gear 48 rotates synchronously. By the meshing transmission of the small gear 48 and the tooth 49, the barrier ring 46 is forced to rotate until the barrier ring 46 rotates 90 degrees. At this time, the channel 53 is in alignment with the opening of the pipeline a23, and the adsorbent can be recycled and regenerated.

[0028] Furthermore, a blanking member 54 adapted to the breathable partition 6 is provided on the drying tower 2. The blanking member 54 includes: a cylinder 56 is fixed on the drying tower 2 through a bearing frame 55. The output end of the cylinder 56 penetrates the drying tower 2. A toothed frame 57 is fixed to the output end of the cylinder 56. A shaft body b58 is rotatably connected to the breathable partition 6. A spur gear c59 meshingly connected to the toothed frame 57 is fixed to the shaft body b58. A barrier disc 60 is fixed to the shaft body b58 and the barrier disc 60 is in contact with the breathable partition 6. A through hole a61 is opened on the breathable partition 6, and a through hole b62 identical to the through hole a61 is opened on the barrier disc 60. A guide rod 66 is fixed to the drying tower 2, and a guide plate 67 is fixed to the toothed frame 57, and the guide plate 67 is slidably penetrated by the guide rod 66. Through the addition of the guide rod 66 and the guide plate 67, the stability of the toothed frame 57 during movement can be significantly improved, avoiding the situation of the toothed frame 57 shaking; Among them, a limiting plate 63 is fixed to the barrier disc 60, and a limiting rod 64 is fixed to the breathable partition 6. When the barrier disc 60 rotates 90 degrees, the limiting plate 63 comes into contact with the limiting rod 64, thus playing a limiting role on the barrier disc 60. At this time, the through hole b62 on the barrier disc 60 is in alignment with the through hole a61 on the breathable partition 6, causing the adsorbent on the breathable partition 6 to fall to the bottom of the drying tower 2 through the through hole a61 and the through hole b62; Specifically, the barrier disc 60 is provided with holes smaller than those on the breathable partition 6, which can ensure that air can pass through the barrier disc 60, avoiding the situation of affecting the air intake efficiency due to excessive blocking interference; Principle of dropping the adsorbent onto the lower breathable partition 6 using the blanking part 54: Driven by the cylinder 56, the toothed frame 57 moves synchronously. Utilizing the meshing and driving effect between the toothed frame 57 and the spur gear c59, the shaft body b58 rotates, driving the barrier disk 60 to rotate until the barrier disk 60 rotates 90 degrees, causing the through hole b62 to coincide with the through hole a61, thereby ensuring that the adsorbent smoothly drops onto the lower breathable partition 6.

[0029] Example 2: Please refer to Figure 8 and Figure 9 This embodiment further elaborates on Example 1, and the difference lies in a way of filtering the intake air.

[0030] Specifically, the air filtering unit 5 includes: a tank body 12 fixed on the frame 1, the tank body 12 is fixed to the three-way pipe a4 through a connecting pipe, a filter element 13 is arranged inside the tank body 12, a sealing cover plate 14 is rotatably connected to the tank body 12, and a screw rod 16 is rotatably connected to the tank body 12 through a rotating seat 15. A groove 17 is opened on the sealing cover plate 14, and the screw rod 16 is located inside the groove 17. A wing nut 18 is threadedly connected to the screw rod 16, and the wing nut 18 abuts against the sealing cover plate 14; In addition, a supercharger is fixed on the frame 1, and the supercharger is connected to the tank body 12 through a bent pipe. The supercharger pressurizes and conveys air into the drying tower 2 to prevent the dispersion mechanism 11 from not operating properly due to too small air flow velocity. And the supercharger is selected according to the actual compressed air flow rate and pressure to ensure a reasonable air flow velocity through the adsorbent and avoid the penetration caused by too high flow velocity; It should be noted that through the setting of the air filtering unit 5, the oil stains in the air can be filtered efficiently and thoroughly. This process effectively avoids the adsorption of oil stain particles on the surface of the adsorbent, thereby preventing the gradual formation of an oil film on the surface of the adsorbent. The formation of this oil film will seriously affect the adsorption performance of the adsorbent. Therefore, through the efficient filtration of the air filtering unit 5, it is ensured that the adsorption efficiency of the adsorbent can be maintained at a constant and efficient state for a long time, avoiding the problem of decreased adsorption capacity caused by the accumulation of oil stains; It should also be noted that with the setting of the screw rod 16 and the wing nut 18, it is convenient for users to disassemble the filter element 13, thereby saving the replacement time of the filter element 13, and the structure is simple and reliable; Principle of disassembling the filter element 13: By rotating the wing nut 18, utilizing the threaded driving effect between the wing nut 18 and the screw rod 16 until the wing nut 18 is separated from the screw rod 16, the sealing cover plate 14 can be flipped, so that the filter element 13 inside the tank body 12 can be disassembled, facilitating the replacement or cleaning of the filter element 13.

[0031] Example 3: Please refer to Figures 10 - 14, this embodiment further illustrates other embodiments, and the difference lies in a feeding method of limestone.

[0032] Furthermore, the dispersion mechanism 11 includes: a rotating shaft a36 is rotatably connected to the drying cylinder 20, a fan blade 37 is fixed on the rotating shaft a36, a rotating shaft b39 is rotatably connected to the drying cylinder 20 through a mounting seat a38, and the rotating shaft b39 and the rotating shaft a36 are meshed and driven by two bevel gears a40. A rotating shaft c41 is rotatably connected to a plurality of air-permeable partition plates 6, and the rotating shaft c41 and the rotating shaft b39 are meshed and driven by two spur gears a42. A plurality of dispersion plates 43 are fixed on the rotating shaft c41, and the dispersion plates 43 are in contact with the air-permeable partition plates 6; It should be noted that the fan blade 37 is located directly above the air inlet pipe 3 to ensure that the compressed air can blow the fan blade 37 to rotate, and the dispersion plate 43 is triangular in shape to prevent the adsorbent from staying on the dispersion plate 43; The principle of the dispersion mechanism 11 stirring the adsorbent in the drying tower 2: When the air blows the fan blade 37, the rotating shaft a36 rotates synchronously. By using the meshing and driving effect of the bevel gear a40, the rotating shaft b39 rotates. With the meshing and driving effect of the spur gear a42, a plurality of dispersion plates 43 are driven to rotate, which can stir the adsorbent. It can not only accelerate the adsorbent into the pipeline a23, but also ensure that the adsorbent smoothly falls from the through hole a61 and the through hole b62 onto the lower air-permeable partition plate 6.
