Abstract

Bei Entwässerungs- und Trocknungsvorrichtungen, welche aus einer Entwässerungszentrifuge und einem dazu konzentrisch angeordneten Zerstäubungstrockner bestehen, können Betriebsstörungen auftreten, welche durch Anlagerungen und Verkrustungen von Feststoff-Partikeln im Innenraum des Trockners verursacht werden. Um diese Betriebsstörungen zu vermeiden, wird vorgeschlagen, daß an der Zentrifugentrommel (2) gasansaugende und gasauswerfende Blaseschaufeln (33, 34) befestigt sind, welche mit feststehenden Umlenkflächen (29, 47, 48) zusammenwirken, die im Bereich der Abwurföffnung (4) der Zentrifuge (1) vorgesehen sind.
