Abstract

Sepn. and dewatering of solids is claimed which are intermingled with fibres e.g. animal hair or plant fibres and present at a concn. of less than 10% in waste water from animal compounds or industrial processes. The waste water is introduced into a pressure conveyor separator which is motor driven and extends into a sieve basket, the solid material is formed into a solid shaped object almost free of water and removed from the separator. The sliding contact of the solid material object with the wall of the sieve basket parallel to the feed direction assists in the removal of water.

Description

In der Patentanmeldung P 39 25 650.2 wurden Verfahren zur Pfropfenbildung in, und Vorrichtungen zur Gestal­ tung von Preßschneckenseparatoren dargestellt. Die Aufgabe der Separation von Feststoffen aus Flüssig­ keiten wird in der Anmeldung dadurch gelöst, daß nach einer Schnecke mit gleichbleibender Steigung der im letzten Teil des Siebkorbes und im nachfolgenden Mundstück befindliche Pfropfen sich gegen die parallelen zylindrischen Wände verspannt. Methods were described in patent application P 39 25 650.2 for plug formation in, and devices for gestal tion of press screw separators shown. The The task of separating solids from liquids speed is solved in the application by: a snail with a constant slope of the in last part of the strainer and in the following Plugs located against the mouthpiece parallel cylindrical walls braced.  

Die im Anspruch 17 dargestellte Veränderbarkeit der Länge des Mundstückes gleicht qualitative Schwankungen nicht selbständig aus.The changeability shown in claim 17 The length of the mouthpiece equals qualitative fluctuations not independently.

Daher wurde in Anspruch 18 und 19 eine automatische motorische Verstellung des Mundstückes vorgeschlagen. Eine robustere und einfachere Lösung der Ausstoßrege­ lung wird in der Zusatzanmeldung dargestellt.Therefore, an automatic was in claim 18 and 19 Motorized adjustment of the mouthpiece proposed. A more robust and simple solution to the emission rain is shown in the additional application.

Der Ausgleich der schwankenden Arbeitsweise des Schneckenpreßseparators durch Unterschiede in der Kon­ sistenz der Gülle wird dadurch erreicht, daß zur Regu­ lierung der Geschwindigkeit des Pfropfenaustrittes im unteren Bereich des zylindrischen Mundstückes am Aus­ tritt des Feststoffes ein gewichtsbelasteter Hebel an­ geordnet wird, der bei weicher werdendem Feststoff 20-30% der Ringfläche bedeckt und bei fester wer­ dendem Feststoff die gesamte Ringfläche freigibt.The balancing of the fluctuating workings of the Screw press separators due to differences in the con The manure is achieved by regu the speed of the plug outlet in the lower area of the cylindrical mouthpiece at the end a weight-loaded lever occurs on the solid is arranged, the softening solid 20-30% of the ring area is covered and for those who are firmer the solid releases the entire ring surface.

Ein Ausführungsbeispiel wird im Bild dargestellt. An embodiment is shown in the picture.  

Für den Ausgleich der schwankenden Arbeitsweise des Schneckenseparators durch Unterschiede in der Kon­ sistenz der Gülle ist im unteren Bereich des zylindri­ schen Mundstückes als Hebel ein Flacheisen (1) mit 2 Fahnen (2) an einem Drehelement (3) befestigt. Damit kann über den Hebelarm (4) die mit dem Gewicht (5) einstellbare Belastung auf das Flacheisen und die Fah­ nen übertragen werden.To compensate for the fluctuating operation of the screw separator due to differences in the consistency of the manure, a flat iron ( 1 ) with 2 flags ( 2 ) is attached to a rotating element ( 3 ) in the lower area of the cylindrical mouthpiece as a lever. This means that the load that can be set with the weight ( 5 ) can be transferred to the flat iron and the flags via the lever arm ( 4 ).

Bei dem durch Veränderung in der Konsistenz der Suspension weicher werdenden Feststoff wird der Aus­ stoß desselben durch Abdecken von 20-30% der Ring­ fläche verzögert und so ein höherer Preßdruck zur besseren Flüssigkeitsabscheidung aufgebaut.By changing the consistency of the Suspension softening solid becomes the end bump it by covering 20-30% of the ring area delayed and so a higher baling pressure better liquid separation.

Bei fester werdendem Feststoff öffnet sich die Ab­ deckung durch den höheren Preßdruck, wobei ein leichter Ausstoß des Feststoffes erreicht wird.When the solid becomes solid, the Ab opens coverage by the higher pressure, being a easy discharge of the solid is achieved.
