Abstract
A centrifugal separator provides for 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 and integral feed liquid accelerator and feed holes. The piston/extrusion assembly is used with pasty solids, and includes a piston ( ) extending into a bowl ( ) and having openings ( ) permitting fluid communication across the piston. After separation is complete, a centrate valve ( ) closes one end of the bowl, and the piston is moved axially in the bowl by an actuator. A bowl suspension employs a spherical mounting structure ( ) and a short spindle ( ). A bearing ( ) and the spindle ( ) of the bowl are mounted within the bearing housing. The suspension is retained by a ring and retaining member secured to the separator in compressive contact with the spherical portion of the bearing housing.
