ABSTRACT:
A nonreturn valve connected to a passage venting a gas-containing part of the filtrate collection chamber is located in a centrifuge drum base is operated as a siphon to increase the pressure differential, thus filtration rate, across the centrifuge filter or alternatively a system of rotatable siphon cups connected to the chamber are provided so that gas collecting in the collection chamber during filtration may be evacuated of the centrifuge. This device can also be used in the discontinuously operating filter centrifuge with a rotating siphon whose housing interior is at the pressure of the surroundings or is acted on with a gas pressure for additional acceleration of the filtration.
