Description

Technical Field

[0001] This utility model relates to the field of refrigerated dryer technology, and more specifically, to a refrigerated dryer. Background Technology

[0002] A refrigerated air dryer is a device used to dry compressed air. Its main function is to remove moisture from compressed air, preventing condensation in pipes and equipment, thus avoiding problems such as corrosion, blockage, and pollution. Refrigerated air dryers are widely used in industrial, medical, and food processing fields. They utilize refrigerant to exchange heat with compressed air, lowering the compressed air temperature to a dew point temperature range of 2–10°C. With the continuous development of the refrigerated air dryer industry, more and more companies are entering the air compressor industry, and more and more people are showing interest in refrigerated air dryers.

[0003] In existing technologies, the gas introduced into the intake pipe often contains impurities, and dust and fumes can easily clog the intake pipe. External filters are typically used for filtration, but these are inconvenient and difficult to disassemble and clean. Furthermore, existing heat exchanger structures mostly use bolts to connect the heat exchangers to the inside of the refrigerated dryer, making maintenance difficult. While bolted connections are easy to disassemble, multiple bolts need to be removed for maintenance and replacement, increasing maintenance time and difficulty. Special tools are usually required to loosen the bolts, and over time, rust can form on the bolts, further increasing the time required to loosen them and reducing their practicality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a refrigerated dryer to solve the technical problems mentioned in the background art, such as the inconvenience of disassembling and cleaning filters and the time-consuming and labor-intensive maintenance of heat exchange tubes.

[0008] The present invention is further configured such that the filtration device includes three filter rings, each of which is provided with a filter screen, a filter plate, and an activated carbon plate, to facilitate the filtration, dust removal, and oil removal of the incoming compressed gas.

[0009] The present invention is further configured such that the filter ring is provided with a filter block, and the mounting pipe and the air inlet pipe are provided with filter grooves that cooperate with the filter block, so as to restrict the position of the fixing ring.

The filter device includes a fixed knob 14 and three filter rings 15. Each filter ring 15 has a filter screen 16, a filter plate 17, and an activated carbon plate 18. Each filter ring 15 has a filter block 19. The mounting pipe 4 and the air inlet pipe 2 have filter grooves 20 that cooperate with the filter blocks 19. The filter blocks 19 have symmetrical rubber protrusions 21 on both sides. The filter grooves 20 have grooves 22 on both sides that cooperate with the rubber protrusions 21. The air inlet pipe 2 has symmetrical moving grooves 23. The moving grooves 23 have sliding plates 24. The sliding plates 24 have moving rods 25. One end of the moving rods 25 is fixedly connected to the bottom of the limiting plate 7. A moving spring 26 is provided between the sliding plates 24 and the moving grooves 23.

Then, the fixing knob 14 is turned, which drives the fixing screw 11 to rotate. The fixing screw 11 drives the fixing block 12 to slide along the sliding track 29. The fixing block 12 drives the clamping ring 13 to clamp and fix the heat exchange tube 3, which facilitates the installation of the heat exchange tube 3. When cleaning and maintaining the heat exchange tube 3, only the fixing knob 14 needs to be turned, without the need to disassemble a lot of bolts.

The limiting handle 30 drives the limiting plate 7 to move upward, and the limiting plate 7 drives the limiting rod 8 to move upward. At the same time, the limiting plate 7 drives the moving rod 25 and the sliding plate 24 to squeeze the moving spring 26 in the moving groove 23. By aligning the insertion rod 5 and the insertion hole 6, the installation tube 4 and the air inlet tube 2 are aligned and spliced. Then the limiting handle 30 is released, and the limiting plate 7 drives the limiting rod 8 to move downward under the elastic force of the moving spring 26 and extends into the limiting hole 9 of the insertion rod 5, thereby fixing the position of the insertion rod 5 and facilitating the installation of the installation tube 4. By setting the filter screen 16, filter plate 17 and activated carbon plate 18, it is convenient to remove dust and oil from the compressed gas entering the air inlet tube 2, thereby preventing grease and other dust from entering the heat exchange tube 3.
