Abstract:
1. A centrifugation dewatering apparatus wherein a water-draining basket for accommodating a material to be dewatered is rotatably provided to an apparatus main body, and the water-draining basket is rotatably driven, thereby centrifugally removing moisture that has adhered to the material to be dewatered, the centrifugation dewatering apparatus being characterized in that a hollow rotating shaft part that is caused to rotate using a drive source is vertically provided to the apparatus main body; the water-draining basket, which rotates in tandem with the rotating shaft part, is provided to the periphery of the rotating shaft part; the interior of the hollow rotating shaft part and the interior of the water-draining basket are provided in a communicating state; air introducted into the rotating shaft part is introduced into the water-draining basket via the interior of the rotating shaft part when the material to be dewatered that is accommodated in the water-draining basket is centrifugally dewatered by the rotation of the rotating shaft part driven by the drive source; the water-draining basket is raisable provided to the apparatus main body; a port for introducing the material to be dewatered is provided to an upper part of the water draining basket; a port for extracting the material to be dewatered is provided to a lower part of the water-draining basket; a landing part that ortates together with the rotating shaft part is provided to the rotating shaft part, said landing part forming a bottom surface onto which the material to be dewatered lands after having introduced in the water-draining basket via the port and after the extraction port is closed; and lifting the water draining basket causes the extraction port to be lifted away from the landing part thereby the material is tto dewatered falls unassistedly to be extracted from the extraction port.
