[0002] In the industrial production field, compressed air plays a key role as the "power source" and is the core driving force for the operation of many mechanical equipment. However, the compressed air produced from the compressor often contains a large amount of moisture and impurities, which are like hidden "small troubles" that may interfere with the operation of precision equipment at any time, leading to frequent failures and seriously affecting product quality. At this time, the refrigerated rapid cooling and dehumidification compressed air drying equipment is like a "super guardian", shouldering the important task of purifying compressed air and ensuring stable production operation.

[0003] After long-term use, dust and debris accumulate on the inner wall of the pipe, which reduces the heat exchange efficiency and prevents the gas from effectively exchanging heat.

The inner wall of the second connecting pipe 39 is connected to one end of the second spring 313, and the other end of the second spring 313 is connected to the side wall of the cleaning ring 314. The surface of the cleaning ring 314 is slidably connected to the inner wall of the second connecting pipe 39. One end of the connecting rod 23 is rotatably connected to the side wall of the driven wheel 24, and the other end of the connecting rod 23 is rotatably connected to one end of the piston rod 32. The upper end face of the base 1 is connected to the freezer 31. The side wall of the sleeve 35 is connected to the inner wall of the freezer 31. The front of the freezer 31 is connected to the filter box 34. The inner wall of the filter box 34 is slidably connected to the filter plate 36. The upper end face of the freezer 31 is connected to the air inlet pipe 4. The bottom end of the air inlet pipe 4 passes through the inner wall of the freezer 31 and communicates with the inside of the sleeve 35. The two ends of the first connecting pipe 38 are respectively connected to the inside of the sleeve 35 and the connecting box 37. The two ends of the second connecting pipe 39 are respectively connected to the inside of the connecting box 37 and the filter box 34.

[0032] In Embodiment 1, the drive assembly 2 includes a servo motor 21, a support box 22, a connecting rod 23, a driven wheel 24, and a driving wheel 25. The lower end face of the support box 22 is connected to the upper end face of the base 1. The side of the driven wheel 24 is rotatably connected to the inner wall of the support box 22. The side wall of the driving wheel 25 is rotatably connected to the inner wall of the support box 22. The surfaces of the driven wheel 24 and the driving wheel 25 are connected by a drive belt.

[0033] Specifically, the drive wheel 25 rotates under the drive of the servo motor 21, and drives the driven wheel 24 to rotate synchronously through the transmission belt, realizing the transmission of power and the conversion of motion mode. The connecting rod 23 connects the driven wheel 24 and the piston rod 32, converting the circular motion of the driven wheel 24 into the linear motion of the piston rod 32.

[0034] In the second embodiment, the side wall of the servo motor 21 is connected to the right side of the support box 22, and the output end of the servo motor 21 passes through the inner wall of the support box 22 and is connected to the center of the drive wheel 25.

[0035] Specifically, the servo motor 21 provides the power source, and its output shaft rotation drives the drive wheel 25 to rotate.

[0036] Working principle:

[0037] First, the servo motor 21 starts, and its output drives the drive wheel 25 to rotate. The drive wheel 25 drives the driven wheel 24 to rotate synchronously through the transmission belt. When the driven wheel 24 rotates, the connecting rod 23, which is rotatably connected to its side wall, will make a circular motion. Since the other end of the connecting rod 23 is rotatably connected to the piston rod 32, the circular motion of the driven wheel 24 is converted into the linear motion of the piston rod 32.

[0038] Compressed air containing moisture and impurities enters the freezer 31 through the intake pipe 4. The low temperature environment inside the freezer 31 cools the compressed air, causing the water vapor to condense into liquid water, achieving initial dehumidification. Simultaneously, some impurities may adhere to the inner wall of the freezer 31 due to the cooling process. The piston rod 32, driven by the drive assembly 2, performs reciprocating linear motion. A cleaning rod 33 connected to one end of the piston rod 32 slides within the first connecting pipe 38. When the piston rod 32 moves into the sleeve 35, the cleaning rod 33 cleans the impurities adhering to the inner wall of the first connecting pipe 38, ensuring smooth gas flow within the first connecting pipe 38. The gas then enters the connecting box 37 through the first connecting pipe 38. As the gas flows downwards... The sealing plate 311 is pushed downward and the first spring 312 is stretched. Then, the gas enters the second connecting pipe 39. The gas pushes the cleaning ring 314 to move and stretches the second spring 313, cleaning the impurities on the inner wall of the second connecting pipe 39. When the piston rod 32 moves outward from the sleeve 35, the first spring 312 pushes the sealing plate 311, so that the sealing plate 311 and the fixed plate 310 maintain a certain sealing state to prevent gas backflow. At the same time, the cleaning ring 314, lacking the push of the gas, returns to its original position under the elastic force of the second spring 313 and continues to work next time. The one-way valve 315 in the piston rod 32 makes the gas flow only in one direction to prevent backflow and ensure that the gas can only be pushed into the sleeve 35 by the piston rod 32.

[0039] After being processed by the drying component 3, the gas enters the filter box 34, where the filter plate 36 further filters impurities from the gas, ultimately resulting in dry and clean compressed air. This completes the entire workflow.
