Abstract
Der Sinkscheider weist eine langgestreckte, kanalförmige Sink-Schwimmkammer 6 mit parallelen Seitenwänden auf, die als sog. "Einkammer", d.h. ohne Quer- oder Trennwand, aus gebildet ist. Die Sink-Schwimmkammer ist im Längsschnitt als auf der Spitze stehendes ungleichschenkliges, rechtwink liges Dreieck ausgebildet, wobei die Hypotenuse die Ober fläche der Schwertrübe bildet. Die Spitze des Dreiecks bildet den tiefsten Punkt 15. Dieser tiefste Punkt 15, von dem der Förderer 3 zum Austrag des Sinkgutes ausgeht, liegt zwischen der in der Mitte erfolgenden Aufgabe 9 und dem Überlaufwehr 5 für das Schwimmgut. Die Förderschnecke tritt an dem dem Überlaufwehr 5 gegenüberliegenden Ende aus der Sink-Schwimmkammer aus. In diesem Bereich ist die Schnecke als Bandschnecke 4 ausgebildet. Die einfach ausgebildete Vorrichtung erlaubt ein sauberes Trennen von Schwimm- und Sinkgut und selbst solches Schwimmgut, das in der Nähe des Austritts der Förderschnecke aufschwimmt, gelangt durch die ungehinderte laminare Strömung über die gesamte Oberfläche der Schwertrübe zum Überlaufwehr. Diese Strömung kann durch zusätzliche Befüllrohre 8 für Schwertrübe unterstützt werden. The sink separator has an elongated, channel-shaped Sink-floating chamber 6 with parallel side walls that as a so-called "single chamber", i.e. without cross or partition wall is formed. The sink-swimming chamber is in longitudinal section as standing on the top of the isosceles right angle formed triangle, the hypotenuse the upper surface of the dark sludge forms. The top of the triangle forms the lowest point 15. This lowest point 15, of which the conveyor 3 runs out to discharge the sinking material between the middle task 9 and the Overflow weir 5 for the floating material. The screw conveyor kicks in at the end opposite the overflow weir 5 from the Sink swimming chamber off. In this area is the snail designed as a conveyor screw 4. The simply trained Device allows a clean separation of swimming and Sink material and even such floating material that is close to the Exit of the screw conveyor floats through the unobstructed laminar flow over the entire surface the heavy cloud to the overflow weir. This flow can pass through additional filling pipes 8 for heavy sludge are supported.
