[0129] On the other hand, when the rotating part 150 is rotated 120°, the discharge hole of the suction device 162 is connected with the second hole 152, the second hole 152 is communicated with the second path hole 142, and the third hole 153 is located above the first path hole 141. At this time, when the suction device 162 works, i.e. negative pressure is generated, gas can be sucked from the outside through the suction pipeline 161 and be sucked to the storage container 110 through the discharge hole of the suction device 162, so that the pressure inside the storage container 110 is greater than the atmospheric pressure. In this case, the solid-liquid mixture in the storage container 110 is discharged to the outside of the recycling storage part.
