[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a high-sealing environmentally friendly air drying cylinder, including an air drying cylinder body 1. A side cavity 2 is opened on the outer surface of the air drying cylinder body 1. A fixing block 3 is fixedly connected inside the side cavity 2. A threaded rod 4 is threadedly connected inside the fixing block 3. A lifting plate 5 is movably sleeved at the bottom of the threaded rod 4. Connecting rods 6 are hinged to the left and right sides of the bottom of the lifting plate 5. A movable plate 7 is hinged to the other end of the connecting rod 6. A round rod 8 is fixedly connected to the bottom of the outer side of the movable plate 7. A rotating handle 9 is movably sleeved on the outer surface of the round rod 8. The outer surface of the rotating handle 9 is movably connected to the inner surface of the side cavity 2. A movable shaft 10 is fixedly sleeved on the inner surface of the rotating handle 9. The outer surface of the movable shaft 10 is movably sleeved on the inner wall of the air drying cylinder body 1.

[0023] Rotating the two threaded rods 4 upwards will cause the two lifting plates 5 to move upwards, which in turn will cause the four connecting rods 6 to rotate, causing the four movable plates 7 and the four round rods 8 to move towards each other. When the four round rods 8 separate from the two rotating handles 9, the fixing effect on the rotating handles 9 will be released. Then, pull the rotating handles 9 to rotate 90 degrees around the movable shaft 10. Then, rotate the two threaded rods 4 downwards again to cause the two round rods 8 to reset and be inserted into the two rotating handles 9 respectively to fix them. This achieves the purpose of making it easy to replace the air drying cylinder body 1 by rotating the two rotating handles 9.

[0024] The side cavity 2 has a limiting groove 11 on its rear side, and a limiting block 12 is movably connected inside the limiting groove 11. The other end of the limiting block 12 is fixedly connected to the outer surface of the rotating handle 9.

[0025] The design of the limiting groove 11 and the limiting block 12 serves to limit the rotation handle 9.

[0026] The air drying cylinder body 1 has a connecting plate 13 fixedly connected to the bottom of the body. The connecting plate 13 has an air outlet 14 and an air inlet 15.

[0027] This design allows air to enter the interior of the air drying cylinder body 1 through the air inlet 15, and the air is discharged through the air outlet 14 after being dried.

[0028] Among them, a sealing strip 16 is movably installed at the bottom of the air drying cylinder body 1, and the sealing strip 16 is circular in appearance.

[0029] The design of the sealing strip 16 serves to improve the sealing performance of the air drying cylinder body 1.

[0030] The top of the connecting plate 13 is fixedly connected to a filter element cover 17, and a first circular hole 18 is opened on the outer side of the filter element cover 17.

[0031] The filter element cover 17 is filled with a filter element. Air enters the filter element cover 17 through the air inlet 15, is initially filtered by the filter element, and then is discharged from the first round hole 18.

[0032] The inner shell 19 is fixedly sleeved on the outer surface of the connecting plate 13. The inner shell 19 is filled with molecular sieve 20. A filter screen plate 21 is fixedly installed inside the inner shell 19. An inner cover 22 is movably sleeved inside the top of the inner shell 19. A second round hole 23 is opened inside the inner cover 22.

[0033] The pre-filtered air enters the interior of the inner shell 19 through the second round hole 23, and then is dried by the molecular sieve 20, filtered by the filter screen 21, and discharged through the air outlet 14.

[0034] The top of the inner liner cover 22 is fixedly connected to a spring 24, the top of the spring 24 is fixedly connected to the top of the inner cavity of the air drying cylinder body 1, and a cylindrical block 25 located in the middle of the spring 24 is fixedly installed on the top of the inner liner cover 22. An installation block 26 is movably sleeved on the outer surface of the cylindrical block 25, and the top of the installation block 26 is fixedly connected to the top of the inner cavity of the air drying cylinder body 1.

[0035] The spring 24 is designed to press the molecular sieve 20 and the inner liner cover 22 together, while the cylindrical block 25 and the mounting block 26 are designed to limit the spring 24, preventing the spring 24 from tilting and causing the molecular sieve 20 and the inner liner cover 22 inside the inner liner shell 19 to shake and shift during operation, thereby improving the air drying effect.

[0036] Working principle and usage process of this utility model:

[0037] When drying compressed air, the compressed air first enters the interior of the filter element cover 17 through the air inlet 15. After being initially filtered by the filter element, it is discharged from the first round hole 18 and then enters the interior of the inner shell 19 through the second round hole 23. After being dried by the molecular sieve 20 and the filter screen 21, it is discharged from the air outlet 14.

[0038] Because the air drying cylinder body 1 vibrates during operation, the spring 24 above the inner liner cover 22 will tilt. With the cooperation of the cylindrical block 25 and the mounting block 26, the tilting of the spring 24 is prevented, which causes the molecular sieve 20 and the inner liner cover 22 inside the inner liner shell 19 to shake and shift during operation, thereby improving the air drying effect.

[0039] When replacing the air dryer body 1, rotating the two threaded rods 4 upwards will cause the two lifting plates 5 to move upwards, which in turn will cause the four connecting rods 6 to rotate, causing the four movable plates 7 and the four round rods 8 to move towards each other. When the four round rods 8 separate from the two rotating handles 9, the fixing effect on the rotating handles 9 will be released. Then, pull the rotating handles 9 to rotate 90 degrees around the movable shaft 10. Then, rotate the two threaded rods 4 downwards again to cause the two round rods 8 to reset and be inserted into the two rotating handles 9 respectively to fix them. This achieves the purpose of easily replacing the air dryer body 1 by rotating the two rotating handles 9, improving the convenience and flexibility of replacing the air dryer body 1.
