ABSTRACT:
A rotary discharge type centrifugal separator having a long service life, an energy saving effect, high performance and a high mechanical strength in which the length of a revolving cylindrical bowl is reduced; a high revolution is possible; sludge can be separated by a large centrifugal force; and a paste-like solid component can be efficiently discharged. The rotary discharge type centrifugal separator comprises a revolving cylindrical bowl having a separating zone and a scraping section a screw conveyor shaft coaxially and rotatably held in the bowl, and a pantograph link type scraper which is mounted on the screw conveyor shaft at a portion corresponding to the scraping section and which has four link bars pivotally connected to each other in a rhomboidal shape so that the link bars are supported symmetrically in a plane perpendicular to the axial center of the screw conveyor shaft. A scraping plate is attached to a position near the connecting portions of the link bars so as to scrape sludge by the movement of the scraping plates with a small air gap to the guide surface of the revolving cylindrical bowl.
