Description

Förderschnecke für Schleudermaschinentrommeln Die Erfindung betrifft Förderschnecken für Schleudermaschinentrommeln. Es sind bereits aus zwei in entgegengesetzter Richtung arbeitenden Teilen bestehende Förderschnecken bekannt, die das Gut-nach in der halben Trommelhöhe liegenden Austrittsöffnungen befördern. Hierbei ist der Beförderungsweg des Gutes kurz und deshalb günstig, jedoch weisen diese Schnecken den Nachteil auf, daß sie den ganzen Schleuderraum ausfüllen, wodurch die Verwendung eines Tellereinsatzes im Schleuderraum verhindert wird. Man hat deshalb bei nach einem Ende der Trommel fördernden Schnecken bereits vorgeschlagen, die Schnecke an einem Rippengestell zu befestigen. Diese Gestelle hatten jedoch den Nachteil, daß sie nur schlecht zur Aufnahme der tangentialen-Kräfte geeignet sind.Screw Conveyor for Centrifugal Drums The invention relates to Screw conveyors for centrifugal drums. There are already two in opposite Direction working parts known existing screw conveyors, which the Gut-nach convey outlet openings halfway up the drum. Here is the The transport route of the goods is short and therefore cheap, but these snails have the disadvantage that they fill up the entire centrifugal chamber, which makes it easier to use a plate insert in the centrifugal chamber is prevented. That's why you have to one end of the drum conveying screws already proposed the screw to be attached to a rib frame. However, these frames had the disadvantage that they are poorly suited to absorbing the tangential forces.

Die Erfindung bezieht sich demgegenüber auf eine aus zwei in entgegengesetzter Richtung arbeitenden Schnecken bestehende Förderschnecke, die die festen Stoffe nach dem mittleren Teil der Trommel befördert und die den eigentlichen Schleuderraum frei läßt. Die Erfindung besteht darin, daß die Windungen der Schnecken zur Aufnahme der tangentialen Kräfte untereinander durch ein diagonal verstrebtes Gitterwerk verbunden sind, und daß sie in mittleren Ringen endigen, die durch zweckmäßig mit Kratzern versehene Zwischenstücke verbunden sind. Dabei können die Schienen, aus denen das Gitterwerk besteht, innen scharfkantig und außen abgerundet sein. Die Abb. i und 2 zeigen eine Ausführungsform einer Förderschnecke nach der Erfindung in Aufriß und Querschnitt.In contrast, the invention relates to one of two in opposite directions Direction of working screws existing screw conveyor, which the solid matter conveyed to the middle part of the drum and the actual centrifugal chamber releases. The invention consists in the fact that the turns of the screws to take up the tangential forces among each other through a diagonally braced latticework are connected, and that they end in middle rings, which are expediently connected with Intermediate pieces provided with scratches are connected. The rails can be made where the latticework is made, be sharp-edged on the inside and rounded on the outside. the Figs. I and 2 show an embodiment of a screw conveyor according to the invention in elevation and cross-section.

Die Schleudertrommel besteht aus einem äußeren Mantel g, der durch den Verschlußring 6 mit dem Tzommelunterteil 7 verschraubt ist. In der Trommel ist ein Verteilungsrohr 8 vorgesehen, das von einer Mutter g gehalten wird und das die kegeligen Teller io trägt. Die Welle i i der Förderschnecke ist in der hohlen Welle 12 der Trommel gelagert. Die Windungen der Schnecke befördern die aasgeschleuderten festen Stoffe zu den Ausströmungsmundstücken 13. Die aasgeschleuderte Flüssigkeit steigt nach oben durch Löcher 14 und strömt schließlich durch eine Öffnung 15 aus der Trommel aus.The centrifugal drum consists of an outer jacket g that passes through the locking ring 6 is screwed to the lower part 7 of the drum. Is in the drum a distribution pipe 8 is provided which is held by a nut g and which the conical plate io carries. The shaft i i of the auger is in the hollow shaft 12 of the drum stored. The turns of the screw convey the hurled carrion solids to the discharge mouthpieces 13. The carrion-hurled liquid rises up through holes 14 and finally flows out through an opening 15 the drum off.

Erfindungsgemäß sind die Windungen der Schnecken 18 bis 21 an den Außenseiten von Streben 3 befestigt, die zur Aufnahme der tangentialen Kräfte diagonal geführt sind. Hierdurch werden Dreieckverbindungen hergestellt, die die Widerstandsfähigkeit des Gitterwerks bedeutend erhöhen. Oben und unten sind an den Schnecken Ringe i und 2 vorgesehen. Der Ring 2 ist an einem scheibenförmigen Boden q. befestigt, an dem die Welle ii sitzt. Die Förderschnecken i8 bis 2i endigen erfindungsgemäß in der Mitte in gleichlaufenden Ringen 16 und 17, die am. mittleren Teil der Streben 3 befestigt sind. Zwischen den Ringen 16 und 17 sind Zwischenstücke 22 vorgesehen, die die Verbindung zwischen den Ringen und somit auch zwischen den beiden unabhängigen Schnekkensystemenverstärken und dadurch in hohem Maße die Festigkeit der Schnecken erhöhen. Die Zwischenstücke 22 können geeigneterweise mit Kratzern 23 versehen sein. Die Streben 3 können erfindungsgemäß aus innen scharfkantigen und außen runden Schienen bestehen.According to the invention, the turns of the screws 18 to 21 on the Outer sides of struts 3 attached, diagonally to absorb the tangential forces are led. This creates triangular connections that increase the resistance significantly increase the latticework. At the top and bottom there are rings i and 2 provided. The ring 2 is on a disk-shaped bottom q. attached to where the shaft ii sits. According to the invention, the screw conveyors i8 to 2i end in the middle in co-rotating rings 16 and 17, the middle part of the struts 3 are attached. Intermediate pieces 22 are provided between the rings 16 and 17, which is the connection between the rings and therefore also between two independent screw systems and thus to a great extent the strength the snails increase. The spacers 22 can suitably have scratches 23 be provided. According to the invention, the struts 3 can be sharp-edged from the inside and round rails on the outside.

Die verschiedenen Teile der Schnecken und des Gitterwerks können durch Schweißen zusammengefügt sein.The various parts of the scroll and the latticework can go through Welding be joined together.

Wenn sich die zwischen den Tellern io ausgeschiedenen festen Stoffe nach außen bewegen, trifft ein Teil von ihnen die Streben 3. Wenn die Streben jedoch nach innen ausgeschärft sind, gleiten die festen Stoffe ohne weiteres von ihnen ab und gehen nach außen. Der Durchfluß zwischen den Streben 3 und den äußeren Kanten der Teller io bleibt somit unter allen Umständen frei.If the solids that have separated out between the plates move outwards, part of them meet the struts 3. However, when the struts are sharpened inwards, the solid materials slide off them easily off and go outside. The flow between the struts 3 and the outer edges the plate io thus remains free under all circumstances.
