Patent attributes
According to the present invention, there is provided a centrifugation dewatering apparatus that is capable of using a flow of air to dry a material to be dewatered while the material is being subjected to centrifugation dewatering. A centrifugation dewatering apparatus has a water-draining basket (2) for accommodating a material to be dewatered (i), and the water-draining basket (2) is rotatably provided to an apparatus main body (3). The water-draining basket (2) is rotatably driven, whereby water that has adhered to the material to be dewatered (i) is centrifugally removed. A hollow rotating shaft part (5) that is caused to rotate using a drive source (4) is vertically provided to the apparatus main body (3). The water-draining basket (2), which rotates in tandem with the rotating shaft part (5), is provided to a periphery of the rotating shaft part (5). The interior of the hollow rotating shaft part (5) and the interior of the water-draining basket (2) are provided in a communicating state. Air introduced into the rotating shaft part (5) is introduced into the water-draining basket (2) via the interior of the rotating shaft part (5) when the material to be dewatered (i) that is accommodated in the water-draining basket (2) is centrifugally dewatered by the rotation of the rotating shaft part (5) as provided by the drive source (4). The material to be dewatered (i) is dried using the air flow and the centrifugal force.
