[0002] Adsorption dryers are mainly used for the post-treatment purification of compressed gases. By utilizing the characteristics of adsorbents, the water molecules present in the compressed gases are effectively adsorbed in the adsorbents. Through the principle of pressure swing adsorption, they are recycled and regenerated. The adsorbent is also called molecular sieve, and its main component is alumina. After being used for a period of time, the adsorbent will gradually become ineffective and needs to be replaced with a new one.

[0012] Beneficial effects

[0013] The utility model provides an adsorption type compressed air dryer. Compared with the prior art, the following beneficial effects are achieved:

[0014] 1. For this adsorption type compressed air dryer, by setting up a heating mechanism, when hot air enters the heating shell, if the temperature of the air is relatively low, the air inside the air box contracts, which will cause the piston block and the fixed rod to descend. The fixed rod drives the fixed plate and the ejector rod to descend, and the ejector rod presses the start switch, so that the heating tube starts heating. The heating tube heats the air. After the temperature rises, the air inside the air box expands, and the gas enters the inside of the piston tube, pushing the piston block, the fixed rod, the fixed plate and the ejector rod to rise, and the ejector rod separates from the start switch, so that the heating tube stops heating.

Observe the temperature scale on the limiting rod and move the moving plate to the position of the set temperature. When the temperature inside the heating shell does not reach the set temperature, the ejector rod will press the start switch. After reaching the temperature, the gas inside the air box will reach the expansion volume at this temperature, and the gas pushes the piston block, the fixed rod, the fixed plate and the ejector rod to rise, and the ejector rod separates from the start switch, so that the heating tube stops heating.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: an adsorption type compressed air dryer, including a left adsorption drying tower 5 and a right adsorption drying tower 4. An air outlet pipe 8 is fixed between the top of the left adsorption drying tower 5 and the top of the right adsorption drying tower 4. A connecting pipe 6 is fixed inside the air outlet pipe 8. A communicating pipe 7 is fixed between the connecting pipe 6 and the air outlet pipe 8. An air inlet pipe 3 is fixed between the bottom of the left adsorption drying tower 5 and the bottom of the right adsorption drying tower 4. A heating mechanism 2 is provided at the bottom of the air inlet pipe 3. The heating mechanism 2 includes a heating shell 21, a heating pipe 14, an air box 25, a piston pipe 18, a piston block 26, a fixing rod 27, a fixing plate 19, a top rod 17, a start switch 16 and a power cord 15. A ventilation pipe 1 is fixed on the front surface of the heating shell 21. The top of the heating shell 21 is fixedly connected to the bottom of the air inlet pipe 3. The right side of the air box 25 is fixedly connected to the right side inside the heating shell 21. The upper end of the piston pipe 18 is fixedly connected to the right end of the air box 25. The outer side wall of the piston block 26 is slidably connected to the inner side wall of the piston pipe 18. The top of the piston block 26 is fixedly connected to the bottom of the fixing rod 27. The top of the fixing rod 27 is fixedly connected to the bottom of the fixing plate 19. The bottom end of the top rod 17 passes through the fixing plate 19. A fixing block 9 is fixed to the top of the top rod 17. A tension spring 20 is fixed to the bottom of the fixing block 9. The other end of the tension spring 20 is fixedly connected to the top of the fixing plate 19. The heating pipe 14 is fixed inside the heating shell 21. A power cord 15 is fixed to the outer side wall of the heating pipe 14. The other end of the power cord 15 is fixedly connected to the bottom of the start switch 16. An adjusting mechanism 24 is provided on the left side of the piston pipe 18. When hot air enters the heating shell 21, if the temperature of the air is relatively low, the air inside the air box 25 contracts, which will cause the piston block 26 and the fixing rod 27 to descend. The fixing rod 27 drives the fixing plate 19 and the top rod 17 to descend. The top rod 17 presses the start switch 16, so that the heating pipe 14 starts to heat. The heating pipe 14 heats the air. After the temperature rises, the air inside the air box 25 expands, and the gas enters the inside of the piston pipe 18, which pushes the piston block 26, the fixing rod 27, the fixing plate 19 and the top rod 17 to rise. The top rod 17 is separated from the start switch 16, so that the heating pipe 14 stops heating.

[0023] Further, the adjusting mechanism 24 includes a screw rod 11, a limiting rod 12, a moving plate 13 and two connecting blocks 23. Both ends of the screw rod 11 are rotatably connected to the two connecting blocks 23. The left end of the connecting block 23 is fixedly connected to the right side of the heating shell 21. The screw rod 11 passes through the moving plate 13 and is threadedly connected to the moving plate 13. A rotating block 10 is fixedly provided at the top of the screw rod 11 passing through the upper connecting block 23. Both ends of the limiting rod 12 are fixedly connected to the connecting blocks 23. The limiting rod 12 passes through the moving plate 13. A temperature scale 22 is fixedly provided on the outer sidewall of the limiting rod 12. The bottom of the start switch 16 is fixedly connected to the bottom of the moving plate 13. The power cord 15 passes through the moving plate 13. According to the required temperature, rotate the rotating block 10. The rotating block 10 drives the screw rod 11 to rotate. The rotation of the screw rod 11 causes the moving plate 13 to move. The moving plate 13 drives the start switch 16 to move. Observe the temperature scale 22 on the limiting rod 12 to move the moving plate 13 to the position of the set temperature. In this way, when the internal temperature of the heating shell 21 does not reach the set temperature, the ejector rod 17 will squeeze the start switch 16. After reaching the temperature, the gas in the air box 25 will reach the expansion volume at this temperature. The gas pushes the piston block 26, the fixed rod 27, the fixed plate 19 and the ejector rod 17 to rise. The ejector rod 17 is separated from the start switch 16. In this way, the heating tube 14 stops heating.

[0024] During operation, according to the required temperature, rotate the rotating block 10. The rotating block 10 drives the screw rod 11 to rotate. The rotation of the screw rod 11 causes the moving plate 13 to move. The moving plate 13 drives the start switch 16 to move. Observe the temperature scale 22 on the limiting rod 12 to move the moving plate 13 to the position of the set temperature. Hot air enters the heating shell 21. If the temperature of the air is relatively low and does not reach the set temperature, the air inside the air box 25 shrinks. This will cause the piston block 26 and the fixed rod 27 to descend. The fixed rod 27 drives the fixed plate 19 and the ejector rod 17 to descend. The ejector rod 17 pushes the start switch 16. In this way, the heating tube 14 conducts heating. The heating tube 14 heats the air. After reaching the temperature, the gas in the air box 25 will reach the expansion volume at this temperature. The gas pushes the piston block 26, the fixed rod 27, the fixed plate 19 and the ejector rod 17 to rise. The ejector rod 17 is separated from the start switch 16. In this way, the heating tube 14 stops heating.
