CENTRIFUGAL SEPARATOR

摘要

A screen-bowl type centrifugal separator capable of eliminating productivity lowering caused by clogging by a material to be processed such as crystals in a screen portion as an essential portion of the separator as well as reducing the leak of the material to be processed in the screen portion. Inside a hub (41) of a screw conveyer (40), a cleaning liquid receiver (43) is provided for receiving the cleaning liquid for a cleaning nozzle (45). Inside the cleaning liquid receiver (43), there are provided a plurality of remaining layer cleaning liquid discharge holes (48). The cleaning liquid injected from each of the remaining layer cleaning liquid discharge holes (48) into the bowl (20) is directly injected toward the remaining layered material to be processed through a thin clearance between a narrow-stripe-shaped cover flight (50) extending in the helical direction along the surface (42b) opposite to the material-to-be-processed convey surface (42a) of the flight (42) and the outer periphery of the flight (42).
