Waste is blown up from the rear air chamber through the upper air rectification passage, through the air holes, and upwards to the surface of the porous part at the porous part on the discharge port side of the transport plate, effectively raising the floating effect. receive. In other words, non-combustible materials such as bottles and sands and stones having a high specific gravity, and combustible materials such as bulky plastics and PET bottles having a relatively low specific gravity move toward the discharge port while being separated by a difference in buoyancy. At this time, the non-combustible material moves almost without rising and is discharged from the discharge port, but the combustible material is subjected to a buoyancy force, and especially the bulky combustible material is in a state in which the posture is stabilized so as to minimize the resistance received. Is discharged from the outlet while maintaining the The combustibles discharged from the outlet are
The air blown out from the front air chamber through the lower air rectification passage and from the air outlet is scattered far away without variation in the jumping distance. On the other hand, the incombustibles fall almost directly below without flying out under the influence of the air. By providing the porous portion at the front of the air outlet as described above, the separation of combustibles and non-combustibles by the air blown out from the air outlet is reliably performed.
