[0021] When conveying slag, first put the slag into the feed port 2, then start the motor 5 to rotate the conveying auger 4 to convey the slag to one side of the discharge port 3; At the same time, the dust suction pump 9 is started, and the dust at the feed port 2 is sucked into the first dust suction pipe 7 through the second dust suction pipe 8, and transmitted to the liquid storage chamber 12. Finally, the dust gas is filtered by the first filter plate 14 and discharged from the exhaust pipe 13. This not only improves the working environment, but also reduces pollution to the atmospheric environment.

[0035] Through the setting of the rotating assembly, when the filtered gas is discharged from the exhaust pipe 13, the gas flow drives the fan blades 27 to rotate, and the rotation of the fan blades 27 drives the rotation of the second rotating shaft 26, and the rotation of the second rotating shaft 26 drives the rotation of the rotating plate 25. The rotation of the rotating plate 25 drives the slider 28 to slide inside the movable plate 24, thereby driving the movable plate 24 to move back and forth, and the movement of the movable plate 24 drives the movement of the rack plate 23, and the movement of the rack plate 23 drives the rotation of the gear 22. The rotation of the gear 22 drives the rotation of the first rotating shaft 21, and the rotation of the first rotating shaft 21 drives the rotation of the connecting plate 20.
