Description

Technical Field

[0001] The present invention relates to the field of cold dryers, and in particular to an energy-saving and environment-friendly dehumidification device for cold dryers. Background Art

[0002] Refrigerated dryers play an important role in dehumidification. They effectively remove moisture from the air through the principle of freezing and dehumidification. They are widely used in industrial production and laboratory environments. They have the advantages of protecting equipment, improving product quality, saving energy and increasing production efficiency.

[0003] In actual use, the heat exchange and cooling part of the cold dryers currently on the market only uses a fixed serpentine tube. As a result, the contact between the flowing air and the heat exchange part is not uniform enough, and the cooling uniformity is poor, resulting in poor refrigeration and dehumidification effects. In addition, during the dehumidification process, after the serpentine tube exchanges heat, the air will condense into small water droplets after cooling down and adhere to the serpentine tube, leaving a layer of water film on the surface of the serpentine tube. This will also affect the subsequent heat exchange efficiency, resulting in reduced dehumidification effect. Summary of the Invention

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] As an embodiment of the present invention, a dehumidification mechanism is also included. The dehumidification mechanism includes a second hollow circular plate 27 fixedly connected to the inner wall of the connecting pipe body 1. Circular openings 29 are provided on the inner walls on both sides of the second hollow circular plate 27. An annular sponge 39 is fixedly connected to the inner wall of the second hollow circular plate 27. The lower end of the annular sponge 39 is separated and provided with a notch. A drain port 31 is provided at the inner bottom of the second hollow circular plate 27. Two vertical frames 28 are symmetrically fixedly connected to the inner bottom of the connecting pipe body 1. A rotating tube 32 is horizontally penetrated on both vertical frames 28. The two rotating tubes 32 are aligned with the corresponding vertical frames. The upright frame 28 is rotatably connected via a bearing. The opposite sides of the two rotating tubes 32 extend into the interior of the second hollow circular plate 27 and are connected via a plurality of U-shaped heat conducting tubes 33. The other ends of the two rotating tubes 32 are each mounted with a rotary joint 30. The other sides of the two rotary joints 30 are each connected to a connecting tube 10. The other ends of the two connecting tubes 10 extend to the outside. When in use, the two connecting tubes 10 are connected to the cooling medium flow path of the air compressor. That is, the cooling medium enters at the front connecting tube 10 and is discharged from the rear connecting tube 10 into the subsequent flow path, thereby cooling the plurality of U-shaped heat conducting tubes 33.

[0033] As an embodiment of the present invention, it also includes a rotating mechanism, which is used to drive the rotating tube 32 to rotate. The rotating mechanism includes an L-shaped plate 2 fixedly connected to the upper end of the connecting tube body 1, and a motor 3 is installed on the L-shaped plate 2. The output shaft of the motor 3 extends into the interior of the connecting tube body 1 and is fixedly connected to a third bevel gear 34. A fourth bevel gear 35 is installed on the rotating tube 32, and the fourth bevel gear 35 is meshed with the third bevel gear 34. A fixing rod 36 is fixedly connected between the two rotating tubes 32, and the lower end of the fixing rod 36 is symmetrically fixedly connected to two rectangular bars 37, and the lower end portions of the two rectangular bars 37 are rotatably connected to the opposite sides of the pressing rollers 38;

[0034] As an embodiment of the present invention, it also includes a capturing mechanism, which is used to improve the dehumidification effect. The capturing mechanism includes a first hollow circular plate 16 fixedly connected to the inner wall of the connecting tube body 1, and a plurality of holes are opened on the left and right inner walls of the first hollow circular plate 16. A first rotating shaft 17 is rotatably connected between the left and right inner walls of the first hollow circular plate 16. A fixed plate 19 is fixedly connected to the inner bottom of the first hollow circular plate 16. The upper end of the fixed plate 19 contacts the first rotating shaft 17 and is slidably connected. The upper end of the first rotating shaft 17 is fixedly connected to a rotating plate 18. The front sides of the rotating plate 18 are fixedly connected to arc-shaped sponges 40 (two arc-shaped sponges 40 are shown in a slightly compressed state). The other sides of the two arc-shaped sponges 40 are respectively fixedly connected to the front and rear sides of the fixing plate 19. The right end of the first rotating shaft 17 passes through the first hollow circular plate 16 and is fixedly connected to the first transmission gear 15.

[0035] As an embodiment of the present invention, a piston cylinder 8 is embedded in the inner top of the connecting tube body 1, and a piston block 13 that can slide up and down is provided in the piston cylinder 8. The upper end of the connecting tube body 1 is fixedly connected to the reducer 4. The reducer 4 is a prior art, and its input end speed is greater than the output end speed. The speed ratio here is 10:1. The output shaft of the motor 3 is fixedly connected to the first bevel gear 5, and the input end of the reducer 4 is fixedly connected to the second bevel gear 6. The first bevel gear 5 is meshed with the second bevel gear 6. The output end of the reducer 4 is fixedly connected to the rotating disk 7. The eccentric part of the rotating disk 7 is rotatably connected to the connecting rod 12. The other end of the connecting rod 12 is rotatably connected to the upper end of the piston block 13. The lower end of the piston block 13 is fixedly connected to the rack 14, and the first transmission gear 15 is meshed with the rack 14;

[0036] As an embodiment of the present invention, it also includes a drainage mechanism, which is used to discharge water to the outside without affecting the passage of air. The drainage mechanism includes a connecting column 11 fixedly connected to the lower end of the connecting pipe body 1, a columnar cavity 24 is provided in the connecting column 11, a second rotating shaft 22 is rotatably connected between the inner walls of the left and right sides of the columnar cavity 24, a rotating column 25 is fixedly connected to the second rotating shaft 22, a temporary storage groove 41 is provided on the side wall of the rotating column 25, a drainage port 26 is provided at the inner bottom of the columnar cavity 24, and the inner top of the columnar cavity 24 is provided with a first liquid drop port. 21 and the second liquid drop outlet 20 are connected to the interior of the connecting tube body 1, the lower end of the rack 14 extends into the cylindrical cavity 24, and the outer side of the second rotating shaft 22 is fixedly connected to the second transmission gear 23, and the second transmission gear 23 is engaged with the rack 14. It should be noted that in the present invention, the number of teeth of the first transmission gear 15 is one-fourth of the number of teeth of the second transmission gear 23, and the tooth pitch of the upper end part of the rack 14 is larger, and the tooth pitch of the lower end part is smaller. In actual use, the rack 14 moves up and down once, and the amplitude of the forward and reverse rotation of the first transmission gear 15 will not be too large.

[0037] In the present invention, when in use, the connecting pipe body 1 is connected to the existing air flow channel, allowing the cooling medium in the circulating cooling flow channel to flow. The cooling medium will pass through the left rotating pipe 32, the U-shaped thermal conductive pipe 33 and the right rotating pipe 32, and finally be discharged from the right connecting pipe 10. When the air passes through the air flow channel, the air will quickly cool down after contacting the multiple U-shaped thermal conductive pipes 33. After cooling, the moisture in the air will precipitate and turn into atomized small water droplets, and some of the moisture will be attached to the U-shaped thermal conductive pipe 33.

[0038] During this process, the motor 3 can be started. After the motor 3 is started, the third bevel gear 34 and the fourth bevel gear 35 are driven to rotate the rotating tube 32. After the rotating tube 32 rotates, it drives the multiple U-shaped thermal conductive tubes 33 to rotate. This can not only shake off the small water droplets adhering to the surface of the U-shaped thermal conductive tubes 33, thereby improving the temperature exchange effect, but also allow the air to fully contact the U-shaped thermal conductive tubes 33, thereby improving the comprehensiveness of the cooling effect.

[0039] It should be noted here that the small water droplets thrown off by the centrifugal force will come into contact with the annular sponge 39 and be absorbed by the annular sponge 39. This can prevent the water from being thrown off and adhering to the inner wall of the connecting pipe body 1 and then splashing onto the U-shaped temperature conducting pipe 33 and adhering to it again. In addition, as the two rotating tubes 32 rotate, the fixed rod 36 in the middle will also be driven to rotate. The rotation of the fixed rod 36 will drive the two rectangular bars 37 to rotate, causing the pressing roller 38 to rotate and squeeze the annular sponge 39. The water adsorbed on the annular sponge 39 is pressed and moves along the annular sponge 39, and is squeezed out at the notch of the annular sponge 39 and discharged from the drain port 31.

[0040] The other part of the atomized water droplets in the air will follow the airflow into the two arc-shaped sponges 40 and be absorbed and captured by the arc-shaped sponges 40;

[0041] The rotation of the motor 3 will also cooperate with the first bevel gear 5, the second bevel gear 6 and the reducer 4 to make the rotating disk 7 rotate at a low speed. The rotation of the rotating disk 7 will cooperate with the connecting rod 12 to make the piston block 13 reciprocate up and down. The up and down reciprocating motion of the piston block 13 will make the first transmission gear 15 rotate forward and reverse through the rack 14, so that the first rotating shaft 17 drives the rotating plate 18 to rotate forward and reverse reciprocatingly. The rotation of the rotating plate 18 will make the two arc-shaped sponges 40 reciprocate in compression and expansion, so that the water on the arc-shaped sponges 40 can be squeezed out intermittently, so that the arc-shaped sponges 40 can always capture the atomized water in an excellent state, thereby improving the actual dehumidification effect.

[0042] In addition, the up and down reciprocating motion of the rack 14 will also cause the second rotating shaft 22 to rotate back and forth in both directions through the second transmission gear 23, thereby causing the rotating column 25 to rotate back and forth in both directions. When the rotating column 25 rotates to the point where the temporary storage tank 41 is in the upper position, the water at the bottom of the connecting pipe body 1 will enter the temporary storage tank 41 through the first liquid drop port 21 and the second liquid drop port 20. When the rotating column 25 rotates to the point where the temporary storage tank 41 is in the lower position, the water in the temporary storage tank 41 will be discharged through the drainage port 26, thereby realizing automatic drainage operation, and the drainage process does not affect the passage of air through the connecting pipe body 1.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
