Document Type and Number:
WIPO Patent Application WO/2023/223567
Kind Code:
A1
Abstract:
[Problem] To provide a centrifugal separation device that is able to suppress the generation of vibration when the rotation of a bowl decelerates during, for example, a stopping operation. [Solution] This centrifugal separation device comprises: a bowl that comprises a solid matter discharge port and a separated liquid discharge port, performs solid-liquid separation of solid matter from a liquid by applying a centrifugal force to a processing liquid supplied thereinside, and discharges the separated liquid from the separated liquid discharge port; a screw conveyor that is disposed inside the bowl rotates while having a relative speed difference with the bowl, and conveys the solid matter to the solid matter discharge port; and a liquid drain nozzle that comprises an inflow hole which forms a flow path in a direction that crosses or is oblique to a rotary shaft of the bowl, the leading end of the inflow hole being positioned further toward the rotary shaft side than a sedimentation layer of the solid matter formed on the bowl inner circumferential surface due to normal operations.
