摘要
A centrifugal separator provides for automatic discharge of solids by either an axial-motion scraper or a piston/extrusion assembly. The axial-motion scraper is used with hard-packed or friable solids, and includes an integral feed liquid accelerator and feed holes. The piston/extrusion assembly is used with pasty solids, and includes a piston extending into a separator bowl and having openings permitting fluid communication across the piston. After high-speed separation is complete, a centrate valve closes one end of the bowl, and the piston is moved axially in the bowl by an actuator. Accumulated solids are scraped from the sides of the bowl and extruded out of the piston openings for discharge from the bowl. A bowl suspension employs a spherical mounting structure and a short, stiff spindle. A spherical portion of a bearing housing is mounted in a spherical mounting region at one end of the separator, with a cylindrical portion of the bearing housing extending along the rotational axis. A bearing and the spindle of the separator bowl are mounted within the cylindrical portion of the bearing housing. The suspension is retained by a stiff resilient ring and retaining member secured to the separator in compressive contact with the spherical portion of the bearing housing.
