Description

Technical Field

[0001] This utility model relates to the field of compressed air technology, specifically to a compressed air drying filter. Background Technology

[0002] Compressed air dryer filters are essential filtration devices for improving the quality of instrument air used in factories or laboratories. Compressed air passing through a precision filter element can produce a coalescing effect, where larger particles are adsorbed onto the filter media, and moisture condenses into larger water droplets. The water carrying impurities flows down the bottom to the drain device, where it is discharged through an automatic or electric drain valve, thereby improving the quality of the compressed air.

[0003] Currently, conventional compressed air dryer filters lack a cleaning function for the dryer filter element during use. Therefore, the dryer filter element needs to be disassembled, cleaned, or replaced regularly, which is time-consuming and laborious. In addition, during use, a large amount of water filtered out at the bottom of the dryer filter accumulates, requiring the machine to be stopped for drainage, resulting in the loss of compressed air and making it very inconvenient to use. Therefore, we have proposed a compressed air dryer filter to solve the above problems. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a compressed air drying filter, which solves the problems mentioned in the background section.

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A compressed air dryer filter includes a cylinder. A first limiting mechanism is provided on the inner wall of the cylinder near the lower side, and a second limiting mechanism is fixedly installed on the inner wall of the cylinder near the upper side. An air inlet pipe is fixedly installed on the left side wall of the second limiting mechanism and the left side wall of the cylinder. A dryer filter element is placed between the first and second limiting mechanisms. A sealing cover is threaded onto the upper surface of the cylinder. Limiting rods are evenly arranged circumferentially on the upper inner wall of the sealing cover, and the lower surface of the limiting rods presses the dryer filter element. A cleaning mechanism is provided on the sealing cover and inserted into the dryer filter element. An air outlet pipe is installed on the right side wall of the cylinder near the upper side. A base is fixedly installed on the lower surface of the cylinder, and a drainage mechanism is installed on the lower side wall of the cylinder.

[0006] Furthermore, the first limiting mechanism includes a first partition, a first limiting sleeve, and a circular hole. The first partition is fixedly installed on the inner wall of the cylinder near the lower side. The first limiting sleeve is fixedly installed on the middle of the upper surface of the first partition and is sleeved on the outside of the drying filter element. A circular hole is opened in the middle of the partition corresponding to the first limiting sleeve.

[0007] Furthermore, the diameter of the circular hole is the same as the inner diameter of the drying filter element.

[0008] Furthermore, the second limiting mechanism includes a second partition and a second limiting sleeve. The second partition is fixedly installed on the inner wall of the cylinder near the upper side, and the second limiting sleeve is fixedly installed on the second partition and sleeved on the outside of the drying filter element.

[0009] Furthermore, the cleaning mechanism includes a rotating shaft, a bearing assembly, turbine blades, and a rubber scraper. The rotating shaft is mounted on the upper inner wall of the sealing cover via the bearing assembly. Turbine blades are fixedly mounted on the rotating shaft at a position corresponding to the air intake pipe. A rubber scraper is fixedly mounted on the rotating shaft near the lower side, and the outer surface of the rubber scraper is in movable contact with the inner wall of the dry filter element.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a compressed air drying filter, including a cylinder 1. A first limiting mechanism 2 is provided on the inner wall of the cylinder 1 near the lower side. A second limiting mechanism 3 is fixedly installed on the inner wall of the cylinder 1 near the upper side. An air inlet pipe 4 is fixedly installed on the left side wall of the second limiting mechanism 3 and the left side wall of the cylinder 1. A drying filter element 5 is placed between the first limiting mechanism 2 and the second limiting mechanism 3. A sealing cover 6 is threaded on the upper surface of the cylinder 1. Limiting rods 7 are evenly arranged circumferentially on the upper inner wall of the sealing cover 6, and the lower surface of the limiting rods 7 presses the drying filter element 5 tightly. A cleaning mechanism 8 is provided on the sealing cover 6 and is inserted into the drying filter element 5. An air outlet pipe 9 is installed on the right side wall of the cylinder 1 near the upper side. A base 10 is fixedly installed on the lower surface of the cylinder 1. A drainage mechanism 11 is installed on the lower side wall of the cylinder 1.

[0016] like Figure 2 As shown, in some embodiments, the first limiting mechanism 2 includes a first partition 201, a first limiting sleeve 202, and a circular hole 203. The first partition 201 is fixedly installed on the inner wall of the cylinder 1 near the lower side. The first limiting sleeve 202 is fixedly installed on the middle of the upper surface of the first partition 201 and is sleeved on the outside of the drying filter element 5. A circular hole 203 is opened in the middle of the partition corresponding to the first limiting sleeve 202.

[0017] In this embodiment, the first partition 201 is used to place the drying filter element 5, and the first limiting sleeve 202 limits the outer surface of the drying filter element 5. The round hole 203 allows the impurities and water droplets cleaned on the inner wall of the drying filter element 5 to flow to the lower side of the cylinder 1.

[0018] like Figure 2 and Figure 3 As shown, in some embodiments, the diameter of the circular hole 203 is the same as the inner diameter of the drying filter element 5.

[0019] In this embodiment, the circular hole 203 can better meet the needs of impurities and water droplets falling off the drying filter element 5.

[0020] like Figure 2 As shown, in some embodiments, the second limiting mechanism 3 includes a second partition 301 and a second limiting sleeve 302. The second partition 301 is fixedly installed on the inner wall of the cylinder 1 near the upper side. The second limiting sleeve 302 is fixedly installed on the second partition 301 and is sleeved on the outside of the drying filter element 5.

[0021] In this embodiment, the second partition 301 is used to install the second limiting sleeve 302, so that the second limiting sleeve 302 limits the outer surface of the drying filter element 5, and the second limiting sleeve 302 installs and fixes the air inlet pipe 4. The upper surface of the second limiting sleeve 302 fits against the upper inner wall of the sealing cover 6 to prevent air leakage.

[0022] like Figure 2 and Figure 3 As shown, in some embodiments, the cleaning mechanism 8 includes a rotating shaft 801, a bearing assembly 802, a turbine blade 803, and a rubber scraper 804. The rotating shaft 801 is mounted on the upper inner wall of the sealing cover 6 via the bearing assembly 802. The turbine blade 803 is fixedly mounted on the rotating shaft 801 at a position corresponding to the air intake pipe 4. The rubber scraper 804 is fixedly mounted on the rotating shaft 801 near the lower side, and the outer surface of the rubber scraper 804 is movably attached to the inner wall of the drying filter element 5.

[0023] In this embodiment, the turbine blades 803 are driven to rotate by the compressed air blown in by the intake pipe 4, which causes the turbine blades 803 to drive the rotating shaft 801 to rotate in the bearing assembly 802, which in turn causes the rotating shaft 801 to drive the rubber scraper 804 to rotate, and the rubber scraper 804 cleans the inner wall of the dry filter element 5.

[0024] like Figure 2As shown, in some embodiments, the drainage mechanism 11 includes a liquid level sensor 111, an electric telescopic rod 112, a drain valve 113, and a plug 114. The liquid level sensor 111, the electric telescopic rod 112, and the drain valve 113 are fixedly installed on the lower side wall of the cylinder 1 from left to right. The plug 114 is fixedly installed on the upper surface of the output shaft of the electric telescopic rod 112, and the plug 114 is vertically corresponding to the circular hole 203. The outlet of the drain valve 113 is embedded in the right side wall of the base 10.

[0025] In this embodiment, the liquid level sensor 111 monitors the water level at the bottom of the cylinder 1. When the set height is reached, the information is fed back to the control component. The control component causes the output shaft of the electric telescopic rod 112 to drive the plug 114 to move upward, so that the plug 114 seals the circular hole 203. Then the control component opens the drain valve 113, and the water at the bottom of the cylinder 1 is discharged through the drain valve 113. The water between the first partition 201 and the lower inner wall of the cylinder 1 needs to be discharged before it is full, so that there is compressed air at the bottom of the cylinder 1, so that the water can be pushed out by the gas.

[0026] In use, the intake pipe 4 allows compressed air to enter the second limiting sleeve 302 in the second limiting mechanism 3, causing the compressed air to flow into the drying filter element 5. The drying filter element 5 filters impurities and moisture in the compressed air. The filtered compressed air flows out of the drying filter element 5 and is then discharged through the exhaust pipe 9. The compressed air entering through the intake pipe 4 drives the turbine blades 803 in the cleaning mechanism 8 to rotate, causing the turbine blades 803 to drive the rotating shaft 801 to rotate in the bearing assembly 802. The rotating shaft 801 drives the rubber scraper 804 to rotate, and the rubber scraper 804 cleans the inner wall of the drying filter element 5, allowing impurities or water droplets on the drying filter element 5 to flow out through the round hole 203 in the first limiting mechanism 2. The system directs water towards the bottom of the cylinder 1, effectively preventing the accumulation of impurities or water droplets on the inner wall of the dryer filter element 5, ensuring that the dryer filter element 5 meets the airflow requirements, extending its service life, and improving working efficiency. The liquid level sensor 111 in the drainage mechanism 11 monitors the water level at the bottom of the cylinder 1. When the set height is reached, the information is fed back to the control component. The control component causes the output shaft of the electric telescopic rod 112 to drive the plug 114 upward, so that the plug 114 seals the circular hole 203. Then, the control component opens the drain valve 113, and the water at the bottom of the cylinder 1 is discharged through the drain valve 113. This adds the drainage function of the dryer filter without stopping the machine, making it convenient to use.

[0027] In summary, this compressed air dryer filter, through the air inlet pipe 4 driving the cleaning mechanism 8 to rotate, enables the cleaning mechanism 8 to clean the inner wall of the dryer filter element 5, effectively preventing the accumulation of impurities or water droplets, ensuring airflow, extending the service life, improving work efficiency, and adding a drainage function without stopping the machine, making it convenient to use.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
