The motor is connected with the rotating shaft through a bevel gear, and the rotating shaft is rotatably connected in the first air duct 111 through a connecting piece. When the first air duct 111 needs to be cleaned after long-time use, a worker can start the motor to drive the rotating shaft to rotate, so that the spiral blade on the rotating shaft is driven to rotate, dust on the inner wall of the first air duct 111 is scraped off through the cleaning layer 1521 on the edge of the spiral blade, and the dust is discharged through the dust outlet below the first air duct 111 along with the rotation of the spiral blade. Of course, in other embodiments, the filtering device 14 can also be used together with the cleaning device 15, so as to improve the dust removal efficiency of the dust removal system, which is not described herein again.

The slag bin dust removing system of the slag drying machine is used when the slag bin 3 of the slag drying machine discharges coal slag, when the coal slag starts to be discharged through the slag outlet 31, the synchronous switch 13 synchronously opens the first air duct 111, so that the first air duct 111 can suck air and dust in the coal slag under the action of the negative pressure source 2, the air and the dust can enter the dust removing part 12 to remove dust after entering the first air duct 111, and finally the air which can be tightly caught up in the second air duct 112 can be directly discharged into the environment. When the dust removing system is used for a long time, the first air duct 111 can be cleaned by the cleaning device 15, so that dust removing efficiency is prevented from being reduced due to excessive dust accumulation in the air duct. The dust removing system of the slag bin of the slag drying machine can remove dust from the coal slag when the slag bin 3 of the slag drying machine discharges the coal slag, so that the influence of dust in the coal slag on the health of workers is avoided, and the environment can be protected. And the whole cleaning process is not operated by a worker, and only the first air duct 111 is controlled by the synchronous switch 13, so that human resources can be saved to a certain extent.
