Technical Field

[0001] The utility model relates to the technical field of air dryer devices, in particular to a double-tower adsorption air dryer. Background Art

[0002] The adsorption dryer uses advanced chemical technology. Its principle is to use the difference in volume between water and air molecules to filter out saturated water vapor in the compressed air using a gas purification-specific molecular sieve. The water molecules can be easily adsorbed in the molecular sieve particles, and then the molecular sieve can be restored using a regeneration method. However, the existing adsorption dryers have low internal efficiency, which increases costs.

[0004] Therefore, a double-tower adsorption air dryer is proposed to solve the above problems. Utility Model Content

The inner wall is fixedly connected, and the other side of the filter plate 314 is fixedly connected to the surface of the fixed rod 31. A discharge assembly 39 is provided at the bottom end of the spiral plate 32, and the bottom end of the discharge assembly 39 passes through the outside of the A tower 1. When in use, the spiral plate 32 is filled with adsorbent particles, and the compressed air input into the interior of the A tower 1 through the lower connecting pipe 5 will flow upward. At this time, the compressed air will enter the spiral plate 32 after passing through the filter plate 314. The mesh of the filter plate 314 is smaller than the diameter of the adsorbent particles. Subsequently, under the guidance of the spiral plate 32, the compressed air rises in a spiral shape in the spiral plate 32. During the process, the moisture in the air will be absorbed by the adsorbent.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, the discharge assembly 39 includes a motor 3901 arranged on the surface of the A tower 1, a rotating rod 3902 is rotatably connected to the surface of the spiral plate 32, the other end of the rotating rod 3902 penetrates the A tower 1 and is fixedly connected to the output shaft of the motor 3901, an auger blade 3903 is arranged on the surface of the rotating rod 3902, a discharge pipe 3904 is connected to the bottom of the spiral plate 32, the other end of the discharge pipe 3904 penetrates to the outside of the A tower 1, a valve 3905 is arranged inside the discharge pipe 3904, one side of the valve 3905 penetrates to the outside of the discharge pipe 3904, a protective shell 3906 is arranged on the surface of the A tower 1, and the protective shell 3906 is sleeved on the surface of the motor 3901. When the adsorbent needs to be replaced, the valve 3905 is opened and the motor 3901 is then started. The output shaft of the motor 3901 drives the auger blade 3903 to rotate through the rotating rod 3902, and then the auger blade 3903 drives the adsorbent located below to be discharged through the discharge pipe 3904.

At this time, the compressed air will enter the spiral plate 32 after passing through the filter plate 314. The mesh of the filter plate 314 is smaller than the diameter of the adsorbent particles. Then, under the guidance of the spiral plate 32, the compressed air rises in a spiral shape in the spiral plate 32. During the process, the moisture in the air will be absorbed by the adsorbent.
