CENTRIFUGE FOR SEPARATING MULTICOMPONENT LIQUID MEDIUM Russian patent published in 2000 - IPC

FIELD: liquid separating equipment used in different branches of industry. SUBSTANCE: centrifuge has cylindrical-conical rotor with upper annular chamber, liquid delivery disk, and base enclosing device for discharging condensed solid fraction. Cylindrical filter made in the form of membrane is fixed axially of rotor. Filter wall defines with cylindrical part of rotor annular gap. Filter has device for preliminary filtration of medium to be separated. Membrane-type filtering member is positioned in upper annular chamber above disk for supplying liquid into annular gap so as to define cavity for separating portion of filtered liquid fraction from medium to be separated. This cavity is communicated with filtrate collecting and discharging chamber of cylindrical filter. Condensed solid fraction discharge device is made in the form of disk. Auxiliary filter made in the form of cylindrical-conical chamber is positioned in conical part of rotor, above it. Cylindrical-conical chamber has membrane-type walls which define with rotor wall and cylindrical filter wall gaps for flowing and discharge of separated fractions. Centrifuge of such construction allows multicomponent liquid centrifuging and filtration processes to be combined, self-recovery of filtering members to be provided, separation of liquid medium into three fractions and separation of light component to be performed. EFFECT: increased efficiency, wider operational capabilities, improved separation quality and enhanced reliability in operation. 2 cl, 1 dwg
