The inner drum is provided with a feeding port, the outer drum is provided with a discharging port, and a conical material guide joint which matches the discharging port is provided at the end of the middle drum. The material enters from the spiral guide plate of the inner drum feeding port, and is continuously lifted and longitudinally moved by the lifting plate of the inner drum under the rotation of the drum body, so as to realize downstream drying. The material falls into the middle drum by the action of its own weight at the other end of the inner drum, and moves longitudinally to the other end of the middle drum under the action of the lifting plate of the middle drum, so as to realize countercurrent drying. The material falls into the outer drum by the action of its own weight at the other end of the middle drum, and moves longitudinally to the other end of the outer drum under the action of the lifting plate of the outer drum, and is led out to the discharging port under the action of the conical material guide joint and its material guide plate. The existing conical material guide joint and the discharging pipe are relatively fixed, and their relative positions cannot be adjusted, so they cannot effectively lead out materials of different particle sizes, and blocking is prone to occur. Therefore, a conical material guide joint of the middle drum of the three-drum dryer is needed to solve the above problems. Utility Model Content

[0027] The utility model drives the disc to move by rotating the screw rod, and the disc adjusts the opening and closing angles of the arc plate through the pull rod to adjust the gap size between the arc plate and the discharge pipe, thereby facilitating the discharge of different materials and facilitating adjustment, so that the dryer can dry different materials, thereby improving the use convenience of the dryer.

[0028] A round rod 23 matching the discharge pipe 16 is fixedly disposed on the left side of the screw 20, and an auger 24 matching the discharge pipe 16 is fixedly disposed on the side wall of the round rod 23;

[0029] When the utility model is used, the material flows from the outer cylinder 1 to the discharge pipe 16 for discharge. Under the synchronous action of the hot air and the auger 24, rapid discharge is achieved, ensuring the unobstructed flow of the discharge pipe 16 and the smooth use of the device.

[0030] The side walls of the arc plates 17 are fixed with inclined plates 25; during the use of the present invention, the arc plates 17 and the inclined plates 25 rotate synchronously, and the inclined plates 25 can discharge the material on the lower side of the outer cylinder 1 to avoid material blockage and ensure the normal operation of the device.

[0031] An arc-shaped platform 26 matching the discharge pipe 16 is fixedly provided on the left side of the inner wall of the outer cylinder 1, so as to facilitate the material to flow from the inner part of the outer cylinder 1 to the discharge pipe 16 and facilitate the discharge of the device.

[0032] An arc-shaped baffle 30 matching with the plurality of arc-shaped plates 18 is fixedly provided on the left side of the left first sealing plate 12 to prevent the material from flowing into the circular groove 17 and ensure the normal operation of the screw 20 and the disc 21 .
