A second air duct (63) is also provided on the side of the collection bin (62) away from the recycling bin (1). A filter screen (64) is provided at the connection between the collection bin (62) and the second air duct (63). The filter screen (64) is used to prevent coal dust from being blown into the second air duct (63). An air pump (65) is also provided on the second air duct (63). The air pump (65) is used to transport the airflow in the recycling bin (1) to the second air duct (63).

7. The waste recycling device according to claim 1, characterized in that, The recycling bin (1) is also provided with a second discharge port (13), which is connected to the second screening chamber (15); The second screening chamber (15) is further provided with a conveying component (7), which includes an auger assembly (71) disposed in the second screening chamber (15). The auger assembly (71) includes a spiral shaft (711) rotatably disposed in the second screening chamber (15), and also includes a third power unit (712) disposed on one side of the recycling bin (1). The moving end of the third power unit (712) passes through the outer wall of the recycling bin (1) and is connected to the spiral shaft (711). The third power unit (712) is used to drive the spiral shaft (711) to rotate. 11) The end away from the third power unit (712) is set on one side of the second discharge port (13). The spiral shaft (711) is used to convey the coal slag in the second screening chamber (15) towards the direction closer to the second discharge port (13). It also includes guide plates (72) set on both sides of the spiral shaft (711). The two guide plates (72) are arranged opposite to each other, and each guide plate (72) is inclined on the side wall of the recovery bin (1). The guide plates (72) are used to guide and convey the coal slag located on both sides of the second screening chamber (15) towards the direction closer to the center of the second screening chamber (15).
