Description
Einrichtung zum Austragen der Schleuderrückstände aus kegeligen Siebtrommeln mittels Druckluft. Es ist eine Schleudertrommel zur Abscheidung von festen Stoffen aus Flüssigkeiten bekannt, bei welcher der S.chlewderriickstand mittels Druckluft entfernt wird. Ein beständiges Herausschaffen der Schleuderrückstände während des Betriebes der Schleulder ist bei dieser bekannten Einrichtung nicht mr>glich.Device for discharging the centrifugal residue from conical sieve drums by means of compressed air. It is a centrifugal drum for separating solid matter known from liquids, in which the deficiency residue is removed by means of compressed air Will get removed. A constant removal of the centrifugal residue during the Operation of the Schleulder is not possible with this known device.
Nach der Erfindung wird dagegen ein beständiges Herausschaffen des Schleuderrückstandes während des Betriebes dadurch ermöglicht, daß in einer an sich bekannten kegeligen Siebtrommel ein auf der Leitung für das Druckmittel (Druckluft) drehbarer und verschiebbarer Verteilungskasten mit hintereinanderliegenden in der Austrittsrichtung für das Gut gegen die Trommel geneigten Mundstücken angebracht ist.According to the invention, however, a constant creation of the Centrifugal residue during operation made possible that in a per se well-known conical sieve drum one on the line for the pressure medium (compressed air) rotatable and movable distribution box with one behind the other in the Direction of exit for the material attached to the drum inclined mouthpieces is.
Eine derartige Schleuder ist in der Zeichnung im senkrechten Längsschnitt dargestellt. Das zu schleudernde Gut wird durch den Trichter F in die hohle Welle A eingeführt, an deren Ende die in senkrechter Ebene sich drehende kegelförmige Siebtrommel C angebracht ist. In dieser Siebtrommel ist gleichachsig mit ihr auf der wagerechten Hohlwelle B für die Druckluft oder das sonstige Druckmittel ein Verteilungskasten ra angebracht, der mit mehreren hintereinanderliegenden, in der Austrittsrichtung für das Gut gegen die Trommel C geneigten Mundstücken b versehen ist. Die Siebtrommel wird von einem feststehenden Gehäuse E umfaßt sowie an ihrem offenen Ende von einem drehbaren Auffangring D.Such a sling is in the drawing in a vertical longitudinal section shown. The material to be thrown is through the funnel F into the hollow shaft A introduced, at the end of which the conical rotating in a vertical plane Screen drum C is attached. In this sieve drum is coaxial with her the horizontal hollow shaft B for the compressed air or the other pressure medium Distribution box ra attached, with several one behind the other, in the The direction of exit for the material is provided with mouthpieces b inclined towards the drum C. is. The sieve drum is surrounded by a fixed housing E and on her open end of a rotating catch ring D.
Das in. den Trichter F eingeschüttete Gut verteilt sich nach seinem Austritt aus der Hohlwelle A gleichmäßig über den Boden der Trommel C und bewegt sich dann. an der sich nach außen erweiternden Siebwand der Trommel entlang, wobei das Wasser durch das Sieb hindurchgeschleudert und von dem äußeren Gehäuse E aufgefangen wird, aus dem es durch einen unteren Ablauf abfließt.The material poured into the funnel F is distributed according to its Exit from the hollow shaft A evenly over the bottom of the drum C and moves then. along the outwardly widening screen wall of the drum, wherein the water thrown through the sieve and collected by the outer housing E. from which it flows through a lower drain.
Die aus den Mundstücken b austretende Druckluft trifft in schräger gegen die Austrittsöffnung der Trommel geneigter Richtung auf das auf der Siebfläche befindliche Gut und treibt es vor sich her, bis es über den äußeren Rand der Trommel in den Auffangring D abgeschleudert wird, aus dem es durch Abs'treifer entfernt wird. Die Druckluft wirkt hierbei nicht nur treibend, sondern, auch trocknend.The compressed air emerging from the mouthpieces b hits at an angle towards the outlet opening of the drum inclined direction towards that on the sieve surface and drives it in front of you until it is over the outer edge of the drum is thrown off into the collecting ring D, from which it is removed by a squeegee will. The compressed air not only acts as a driving force, it also has a drying effect.
Der Verteilungskasten a mit den Mundstücken b ist drehbar, damit er nachgeben kann, wenn ein Mundstück gegen einen größeren Klumpen der über die Siebfläche fortgetriebenen Masse treffen sollte. Außerdem kann der Verteilungskasten in geeigneten Fällen eine hin, und her gehende Bewegung erhalten.The distribution box a with the mouthpieces b is rotatable so that it can give way if a mouthpiece hits a larger lump of over the screen surface should hit the expelled mass. In addition, the distribution box can be in suitable Cases receive a reciprocating motion.
