separation disc for a centrifugal separator, stack of separation discs, centrifugal separator, and method for separating at least two components of a fluid mixture that are of different densities.

摘要

The present invention provides a separation disc (1) for a centrifugal separator, said disc being adapted to be comprised in a stack of separation discs within a centrifugal rotor to separate a fluid mixture. the separation disk (1) has a truncated conical shape with an inner surface (2) and an outer surface (3) and a plurality of point-shaped spacer members (4) extending from at least one of the inner surface and the outer surface. the point-shaped spacer members (4) serve to provide gaps between mutually adjacent separation discs (1) in a stack of separation discs, and said plurality of point-shaped spacer members are tip-shaped and tapering. from a base on the surface of the separation disk toward a tip extending at a height from said surface. The present invention further provides a stack of separation discs, a centrifugal separator and a method for separating at least two components from a fluid mixture.
