Abstract

Um ein Blockieren des Materialtransportes zur Zentrifugentrommel zu verhindern, ist eine zwar verhältnismäßig geringe aber belastungsunabhängige konstante Drehzahldifferenz zwischen Trommel und Schnecke erforderlich. Die Erzielung eines schlupf­ freien Antriebs unter Verwendung eines Umlaufge­ triebes ist aufwendig und kompliziert. Der neue Antrieb soll diesen Aufwand vermeiden und die Einrichtung vereinfachen. To block the material transport to Preventing the centrifuge drum is one relatively small but independent of stress constant speed difference between drum and Snail required. Achieving a hatch free drive using a recirculating ge drive is complex and complicated. The new Drive should avoid this effort and the Simplify setup.

Zur Erzielung einer belastungsunabhängigen kon­ stanten Drehzahldifferenz zwischen Trommel und Schnecke sind auf deren Antriebswellen als Zahn­ scheiben ausgebildete Antriebsscheiben angeord­ net, die über endlose Zahnriemen mit auf der Welle eines Antriebsmotors angeordneten weite­ ren Zahnscheiben formschlüssig verbunden werden. To achieve a load-independent con constant speed difference between drum and Snails are on their drive shafts as a tooth disks designed drive disks arranged net that has endless timing belts with on the Shaft of a drive motor arranged wide Ren toothed lock washers are positively connected.

Trennen von Feststoff-Flüssigkeitsgemischen. Separation of solid-liquid mixtures.
