FILTERING CENTRIFUGE WITH TURNABLE INSIDE FILTER Russian patent published in 1996 - IPC

FIELD: filtering centrifuges. SUBSTANCE: filtering centrifuge with turnable-inside-out filter has drum revolving in housing. Drum has radial holes for passage of filtrate; radial holes are covered with turnable inside-out cloth. At one end drum is closed with cover having hole for feeding the medium to be filtered and feeding pipe running through hole. Drum and cover are mounted for axial displacement relative to each other by means of hollow driven shaft inside which load-bearing shaft telescopically moves to and fro for turning the filter material inside out. Load-bearing shaft is provided with motion screw and nut which is engageable with it. Either motion screw or nut is set in rotation by means of electric motor; depending on speed of motion screw or nut relative to speed of hollow shaft, load-bearing shaft moves in hollow shaft to and fro like telescope. EFFECT: enhanced reliability. 10 cl, 4 dwg
