[0024] In this embodiment, the slag to be dried enters the drying barrel 1 from the feed port 2 for drying, and the dried slag is discharged from the discharge port 3. When the drying barrel 1 is filled with slag, the driving hollow shaft 4 slowly rotates, and during the rotation, the rotating shaft 1 6 and the rotating shaft 2 7 are driven to rotate around the driving hollow shaft 4, so that the rotating shaft 1 6 can drive the conveyor belt 8 to rotate through the meshing of the bevel gear 1 9 on the rotating shaft 1 6 and the bevel gear 2 10 on the fixed shaft 5, so that the rotating shaft 1 6 can drive the conveyor belt 8 to rotate, so that the slag on the bottom layer in the advancing direction of the guiding mechanism is guided by the inclined setting of the conveyor belt 8 and the conveyor belt 8.

The rotating driving device 15 can also drive the driving hollow shaft 4 to rotate through a transmission mechanism of two meshing gears, thereby further reducing the rotation speed of the driving hollow shaft 4 through the transmission mechanism of the two meshing gears.

The hot air blown in by the hot air input pipe 18 passes through the air inlet chamber 17 and is blown into the drying barrel 1 through the through slots on the partition plate 16.

[0028] In some embodiments, in order to facilitate the driving of the cutting roller 12 by the rotating shaft 2 7, a transmission mechanism is provided, including a driven shaft 19.

While supporting the conveyor belt 8, the connection stability between the driving hollow shaft 4 and the mounting frame 11 is increased.

[0030] In some embodiments, in order to reduce the resistance of the mounting frame 11 when rotating in the drying barrel 1, a chamfer is provided on the mounting frame 11. Thus, the slag is guided to the conveyor belt 8 by the chamfer, and the sharp chamfer can easily scrape off the hard layer of slag powder cut off from the inner wall of the drying barrel 1.
