摘要： An evertable drum centrifuge has a housing extending along an axis, a hollow filter drum rotatable in the housing about the axis and having a front end wall formed with a fill opening centered on the axis, and a nonrotatable fill tube extending along the axis and having a back end. A fill head complementarily engageable in the fill opening is fitted in a closed position in the fill opening and a suspension to be filtered is introduced through the fill tube and fill opening into the drum. A bearing rotatably supports the fill head on the fill-tube back end and a static seal is engaged between the fill head and the fill opening. A pair of dynamic seals flank the bearing, define with the head and fill tube an annular compartment surrounding the fill tube, and each have a head ring fixed rotationally on the head and having a face, a fill-tube ring fixed rotationally on the fill tube and having a face axially engaging the face of the respective head ring, and a spring urging the faces of the respective fill-tube ring and head ring axially together. The compartment is pressurized with a fluid that is forced from the compartment between the faces of the dynamic seals.

摘要： A centrifugal filter has a centrifuge drum rotatable about an axis and provided with a plurality of sieve support plates lining the drum. Each of the plates is generally flat and rectangular and has a radially inwardly directed inner face. They are each formed with an array of flow grooves extending on and opening radially inwardly at the inner face and each having an outer end and an inner end spaced along the plate therefrom. The flow grooves are of increasing flow cross section from their outer ends to their inner ends. An outlet serves for draining liquid from the inner ends. A filter medium overlies the inner face over the flow grooves. Thus flow is maintained substantially uniform even at the outer groove ends, where relatively little filtrate moves. As a result clogging of these flow grooves is impossible; they will stay clear along their entire lengths.
