In step S9-1, the drive motors of the two rotating shafts pivoted on the stirring tank 25 shown in FIG. 7 are continuously operated in the recovery rotation. The recovery rotation means that the two rotating shafts rotate so as to generate a flow that guides the useful solid and the granular material to the discharge port of the stirring tank. , One rotating shaft is rotated in the forward direction, and the other rotating shaft is rotated in the reverse direction. By this recovery rotation, the mixture of useful solids and particulates in the stirring tank 25 can form a flow in a certain direction toward the discharge port provided in the stirring tank 25 shown in FIG.
Next, in step S9-2, the outlet door is manually opened. In step S9-2, the mixture of useful solids and granules flowing in a fixed direction in step S9-1 is opened from the outlet by opening the outlet door provided at the outlet of the agitation tank 25 shown in FIG. It is gradually discharged.
In step S9-3, the drive motor of the screw conveyor rotates and the separation and recovery device starts recovery. In this step S9-3, the mixture of the useful solid and the particulate matter discharged from the discharge port in step S9-2 is activated by operating the drive motor of the screw conveyor built in the separation and recovery device 8 shown in FIG. The separation and recovery device 8 is transferred from below to above by rotation of the screw conveyor. In the meantime, useful solids and granules are separated, and the useful solids are stored in a dedicated container, while the granules are returned again to the stirring tank 25 shown in FIG. Step S9-3 is continuously operated for 20 to 30 minutes.
Finally, in step S9-4, the outlet door is manually closed. In step S9-4, when the discharge of the mixture of useful solids and granular materials to the discharge port is completed, the discharge port door is closed to complete the recovery. In addition, you may make it perform the opening and closing of the discharge port in step S9-3 and step S9-2 automatically.
