  • Centrifugal separator with cones divided into angular sectors separated by annular gaps
    Patent number: 10092909
    Abstract: The rotary bowl (1) of this centrifugal separator is lined with conical structures divided into sectors (7) separated by angularly offset gaps (9) so as to promote a regular spiral fluid flow therein, which is laminar and enhances separation efficiency significantly: in the case of two-phase or three-phase suspensions, a “cake” is obtained on the side wall (8). A scraper (15) rotating at a slightly different speed may be added to enable simultaneously routing of the solid cake to the outlet and continuous processing.
    Type: Grant
    Filed: June 27, 2013
    Date of Patent: October 9, 2018
