Description

Technical Field

[0001] This utility model relates to the field of air dryer technology, specifically to an adsorption-type air dryer with a flow equalization device. Background Technology

[0002] Adsorption air dryers utilize the physical adsorption properties of adsorbents to remove moisture from compressed air through the pressure swing adsorption principle. The core of this system involves two alternating towers: while one tower adsorbs moisture, the other tower regenerates through depressurization expansion or heating, desorbing the adsorbed moisture and releasing it into the atmosphere. This equipment can achieve an outlet air dew point of -40℃ to -70℃, making it suitable for applications with stringent air dryness requirements, such as electronics, pharmaceuticals, and food processing. Its advantages include no need for an external heat source, continuous air supply, and deep moisture removal; however, its energy consumption and cost are relatively high.

[0003] Utility model patent CN207221648U discloses a squeeze-discharge type adsorption air dryer. The dryer has two adsorption tanks, with a buffer plate fixed to the bottom of each tank. Above the buffer plate is a one-way exhaust squeezer that can slide up and down along the inner wall of the tank. An adsorption bed for water absorption is located between the buffer plate and the one-way exhaust squeezer. The top and bottom of each tank have upper and lower interfaces, respectively. The one-way exhaust squeezer allows exhaust only from bottom to top. The two adsorption tanks are designated as the first and second adsorption tanks. The advantages of this utility model are: low energy consumption. The squeezed-out air is water and wastewater, with almost no loss of air source. This is a low-energy, environmentally friendly, high-performance, and reliable replacement device for compressed air after-treatment facilities. It features microcomputer program control, a perfect human-machine interface, simple operation, easy debugging, and high reliability.

[0004] However, in common adsorption air dryers, air enters the adsorption tank directly during use, and compressed air tends to concentrate in the adsorption bed, causing the adsorbent in the central area to become saturated quickly, while the adsorbent in the peripheral area is not fully utilized. Therefore, an adsorption air dryer with a flow equalization device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adsorption-type air dryer with a flow equalization device, which has the advantages of uniformly diffusing the airflow entering the adsorption tank and making uniform contact with the adsorption bed, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adsorption-type air dryer with a flow equalization device includes an adsorption tank, an adsorption bed fixedly installed inside the adsorption tank, an air inlet at the bottom of the adsorption tank, and a flow equalization component inside the adsorption tank.

[0008] The flow equalization assembly includes four mounting rods fixedly installed on the inner side wall of the adsorption tank. A center plate is fixedly installed at one end of each mounting rod. A mounting bearing is fixedly installed on the top of the center plate. A rotating shaft is fixedly installed on the rotating part of the mounting bearing. A rotating fan blade is fixedly installed at the bottom of the rotating shaft. The rotating fan blade is aligned with the air inlet. A rotating end block is fixedly installed at the top of the rotating shaft. A rotating disk is fixedly installed on the surface of the rotating end block. A plurality of dispersion holes are opened on the top of the rotating disk. The dispersion holes are evenly distributed on the top of the rotating disk.

[0009] Furthermore, there are two adsorption tanks, and a lower pipe is fixedly installed at the bottom of the two adsorption tanks, with both ends of the lower pipe aligned with the two air inlets.

[0010] Furthermore, an air inlet pipe is fixedly installed at the bottom of the lower pipe, and two air inlet valves are fixedly installed on the surface of the lower pipe, with the two air inlet valves located on both sides of the air inlet pipe respectively.

[0011] Furthermore, an upper pipe is fixedly installed on the top of the two adsorption tanks, and an air outlet is opened on the top of the adsorption tanks. The two ends of the upper pipe are aligned with the two air outlets.

[0012] Furthermore, an air outlet pipe is fixedly installed at the top of the upper pipe, and two air outlet valves are fixedly installed on the surface of the upper pipe, with the two air outlet valves located on both sides of the air outlet pipe respectively.

[0013] Furthermore, a support ring is fixedly installed on the surface of the adsorption tank, and two mounting plates are fixedly installed at the bottom of the support ring, with a mounting base plate fixedly installed at the bottom of the mounting plate.

[0014] Furthermore, a mounting bracket is fixedly installed between the two adsorption tanks, and a controller is fixedly installed on one side of the mounting bracket.

[0015] Compared with the prior art, this utility model provides an adsorption-type air dryer with a flow equalization device, which has the following beneficial effects:

[0016] This adsorption air dryer with a flow equalization device uses rotating fan blades at the bottom air inlet of the adsorption tank. The airflow entering the adsorption tank drives the rotating fan blades to rotate, which in turn drives the rotating shaft and rotating disk. The airflow diffuses evenly through the dispersion holes on the rotating disk and then comes into contact with the adsorption bed, increasing the utilization rate of the adsorbent. This solves the problem in common adsorption air dryers where air enters the adsorption tank directly during use, and compressed air tends to concentrate in the adsorption bed, causing the adsorbent in the central area to become saturated quickly while the adsorbent in the peripheral areas is not fully utilized.

[0023] Please see Figures 1 to 4 An adsorption-type air dryer with a flow equalization device in this embodiment includes an adsorption tank 1, an adsorption bed 2 fixedly installed inside the adsorption tank 1, an air inlet 3 at the bottom of the adsorption tank 1, and a flow equalization component inside the adsorption tank 1.

[0024] The flow equalization assembly includes four mounting rods 4 fixedly installed on the inner wall of the adsorption tank 1.

The dispersion holes 11 are evenly distributed on the top of the rotating disk 10.

[0025] Specifically, the airflow enters the adsorption tank 1 through the air inlet 3 and comes into contact with the rotating fan blade 8, causing the rotating fan blade 8 to rotate, which in turn causes the rotating shaft 7 to rotate, which in turn causes the rotating end block 9 to rotate, thereby causing the rotating disk 10 to rotate. The airflow rises to the rotating disk 10 and, after passing through the dispersion hole 11, comes into uniform contact with the adsorption bed 2, increasing the utilization rate of the adsorbent.

After air is adsorbed by the adsorption tank 1, it is transported to the air outlet pipe 17 through the upper pipe 15 and discharged through the air outlet pipe 17.

[0030] Meanwhile, a support ring 19 is fixedly installed on the surface of the adsorption tank 1, and two mounting plates 20 are fixedly installed at the bottom of the support ring 19. A mounting base plate 21 is fixedly installed at the bottom of the mounting plate 20.

[0032] The working principle of the above embodiment is as follows: the airflow enters the adsorption tank 1 through the air inlet 3 and comes into contact with the rotating fan blade 8, which drives the rotating fan blade 8 to rotate, drives the rotating shaft 7 to rotate, drives the rotating end block 9 to rotate, thereby driving the rotating disk 10 to rotate. The airflow rises to the rotating disk 10 and comes into contact with the adsorption bed 2 after passing through the dispersion hole 11.
