Description

Technical Field

[0001] The 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 refrigeration dehumidification. They are widely used in industrial production and laboratory environments. They have the advantages of protecting equipment, improving product quality, saving energy and improving 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 will 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 effects. Summary of the invention

The straight frame 28 is rotatably connected through the bearing, and the opposite sides of the two rotating tubes 32 extend to the inside of the second hollow circular plate 27 and are connected through a plurality of U-shaped thermal conductive tubes 33.

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 right end of the first rotating shaft 17 passes through the first hollow circular plate 16 and is fixedly connected with 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 arranged in the piston cylinder 8. The upper end of the connecting tube body 1 is fixedly connected to a reducer 4, and the reducer 4 is a prior art. The speed of its input end is greater than the speed of its output end. The speed ratio here is 10:1. The output shaft of the motor 3 is fixedly connected to a first bevel gear 5, and the input end of the reducer 4 is fixedly connected to a second bevel gear 6, and the first bevel gear 5 is meshed with the second bevel gear 6. The output end of the reducer 4 is fixedly connected to a rotating disk 7, and the eccentric part of the rotating disk 7 is rotatably connected to a connecting rod 12, and the other end of the connecting rod 12 is rotatably connected to the upper end of the piston block 13, and the lower end of the piston block 13 is fixedly connected to a rack 14, and the first transmission gear 15 is meshed with the rack 14;

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 on 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 a first liquid drop port is provided at the inner top of the columnar cavity 24. 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 columnar cavity 24, the outer side of the second rotating shaft 22 is fixedly connected to the second transmission gear 23, the second transmission gear 23 is meshed 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 quarter 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, and 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 with the multiple U-shaped thermal conductive pipes 33. After cooling, the moisture in the air will precipitate and appear as atomized small water droplets, and a part of the moisture will be attached to the U-shaped thermal conductive pipe 33;

[0038] In 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, which can not only throw off the small water droplets attached to the surface of the U-shaped thermal conductive tubes 33 to improve the temperature exchange effect, but also allow the air to fully contact the U-shaped thermal conductive tubes 33 to improve the comprehensiveness of the cooling.

[0039] It should be noted here that the small water droplets thrown off by the centrifugal force will contact the annular sponge 39 and be absorbed by the annular sponge 39, so as to avoid the situation where the water is thrown off and attached to the inner wall of the connecting pipe body 1 and then splashed onto the U-shaped temperature conducting pipe 33 and attached again. In addition, with the rotation of the two rotating tubes 32, the fixed rod 36 in the middle will also be driven to rotate, and the rotation of the fixed rod 36 will drive the two rectangular bars 37 to rotate, so that the pressing roller 38 rotates to squeeze the annular sponge 39, and the water adsorbed on the annular sponge 39 is pressed to move along the annular sponge 39, and is pressed 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 make the rotating disk 7 rotate at a low speed through the cooperation of the first bevel gear 5, the second bevel gear 6 and the reducer 4. 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 movement 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 reciprocately compress and expand, so that the water on the arc-shaped sponge 40 can be squeezed out intermittently, so that the arc-shaped sponge 40 always has an excellent capture effect on the atomized water, 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 through the second transmission gear 23, thereby causing the rotating column 25 to rotate back and forth. When the rotating column 25 rotates to the temporary storage tank 41 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 temporary storage tank 41 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 implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
