CENTRIFUGAL SEPARATOR AND ITS UNLOADER Russian patent published in 1999 - IPC

FIELD: liquid separating facilities. SUBSTANCE: centrifugal separator has rotor which forms inlet for liquid and discharge chamber 17 arranged around axis of rotation. Liquid in discharge chamber rotates around axis of rotation. Free cylindrical surface of liquid is pointed radially inwards. Fixed unloader 21 passes in discharge chamber 17 from rotating liquid medium radially inwards to central outlet 25 and forms through flow channel 26 with inlet hole 23. To decrease sprinkling of liquid around unloader 21 and entrapping of air by liquid, unloader 21 has outer surface which forms circuit in plane perpendicular to axis of rotation including front line 28 and rear line 29 defined by direction of rotation, directed radially outwards and made curved. Farthest parts of these links are arranged in direction of rotation. Radius of curvature of lines 28 and 29 increases in direction of rotor rotation. Outer surface of unloader has rib 30 on line 29 of circuit which increases stiffness of device. EFFECT: reduced sprinkling of liquid in discharge chamber and its removal from separator at low consumption of energy. 3 dwg
