Abstract

Bei einer Vollmantelzentrifuge, insbesondere zur Trennung von schwer trennbaren Medien unterschiedlicher Dichte bzw. deren Gemische und/oder Suspensionen in eine vergleichsweise leichtere und wenigstens eine schwerere Phase, mit einer auf einer Welle drehbar gelagerten und einen Klärteich in sich ausbildenden Trom­ mel sowie mit Organen zum Eintragen der zu trennenden Medien und zum Austragen der ge­ trennten Phasen, wird vorgeschlagen, daß das Austragsorgan (8) für die leichtere Phase (14) zu einem Überlauf (8a) an einer Trommelstirn­ wand (16) geführt und das Austragsorgan (9) für die schwerere Phase (13) vom tiefsten Bereich (17) des Klärteichs (3) ausgehend mit einer Fördereinrichtung (18) ausgebildet und in den austragsseitigen Teil der Hohlwelle (43b) des Verdrängungskörpers (6) ausmündend angeordnet ist. Dabei kann die Fördereinrichtung (18) als Druckluftflüssigkeitsheber (37) ausgebildet sein. With a full-bowl centrifuge, in particular for separating media that are difficult to separate different densities or their mixtures and / or suspensions in a comparatively easier and at least one more difficult phase, with one rotatably mounted on a shaft and a clarification pond in the developing trom mel and with organs for entering the separating media and to discharge the ge separated phases, it is suggested that the Discharge device (8) for the easier phase (14) to an overflow (8a) on a drum face wall (16) guided and the discharge member (9) for the heavier phase (13) from the deepest area (17) of the clarification pond (3) starting with a Conveyor device (18) formed and in the discharge-side part of the hollow shaft (43b) of the Displacement body (6) arranged opening is. The conveyor (18) can be used as Compressed air liquid lifter (37) formed be.
