ABSTRACT:
Self-cleaning, air-tight drum centrifuge (1a) having flange packing (4) between the stationary discharge conduit (2) for clarified liquid and the rotating neck (7a) of the drum 7. Leaking of air past packing 4, when solids are discharged from the drum in the intermittent self-cleaning step and a vacuum develops in the drum chamber 7b, is prevented by providing in the passageway (11a) between the drum chamber 7b and the discharge conduit 2, a siphon-like section 11. By properly dimensioning the siphon-like section, pressure of more than 1 atmosphere is maintained in the liquid contained in the siphon-like section, whereby such leaking is prevented.
