The working principle of the present invention is: the countercurrent drying principle is used to dry the material, the material moves from top to bottom, and the hot air moves from bottom to top, and the two move countercurrently. In this process, the material is in full contact with the hot air, and the material can be dried quickly. Because the dryer has a multi-layer circular screen assembly, each layer has the same structure and is composed of multiple fan-shaped screen plates. This embodiment uses 16 fan-shaped screen plates, which are driven by the main shaft to move in a circle along the circular track. . When reaching a specific position, the fan-shaped sieve plates will turn over in turn, and the material will be poured into the next layer of fan-shaped sieve plates. The overturning process is shown in Figure 8. When the fan-shaped sieve panels on the same floor pass through the overturning track behind the inspection door, due to the rising inclined track, the pressure rollers of the fan-shaped sieve panels break away from the constraints of the horizontal travel track. The eccentrically designed fan-shaped sieve plate begins to turn over under its own weight, and its pressure roller 214 is pressed by the rising track, and moves under the track under the rotation of the main shaft; until the sieve plate is gradually pressed down when walking to the rising track 521. When the fan-shaped sieve plate moves to the horizontal running track, its pressure roller is bound by the horizontal running track again, and the fan-shaped sieve plate just returns to the horizontal state. The last fan-shaped sieve plate also repeats this action at the position of the turning track, so that the materials will fall to the lower sieve plate one after another. Each layer of sieve plate repeats this process repeatedly, and finally the material is discharged through the bottom conical feeder.

The material is turned over several times and then discharged through the discharge port. The used hot air is extracted from the exhaust hole, and a part of the hot air is circulated into the suction port, and then re-enters the dryer cycle after being heated by the heat exchanger, which greatly reduces the heat loss.

The vertical cylinder dryer of the present invention has the advantages of small footprint, high drying efficiency, convenient operation and reliable action.
