Description

Schleudermaschine mit Austragschnecke, bei welcher das Schleudergut durch Öffnungen des Schneckentragkörpers in die Schleuder eingeführt wird. Den Gegenstand der Erfindung bildet eine Schleuder mit vollständiger Trommel und Austragschnecke, bei der in bekannter Weise das Schleudergut durch Öffnungen des vollen Schneckentragkörpers in die Schleuder eingeführt wird und bei der erfindungsgemäß diese Üffnungen durch mit Schaufeln s versehene Aufprall- bzw. Leitvorrichtungen g überdeckt sind, welche das, z. B. durch einen kegeligen Stutzen, zugeführte Schleudergut auffangen und ihm angenähert die Richtung und Geschwindigkeit der leichteren Bestandteile des Schleudergutes in der Schleudertrommel erteilen.Centrifugal machine with discharge screw, in which the material to be centrifuged is introduced into the centrifuge through openings in the screw support body. The subject the invention forms a centrifuge with a complete drum and discharge screw, in which in a known manner the material to be thrown through openings in the full screw support body is introduced into the centrifuge and through these openings according to the invention Impact or guide devices g provided with blades s are covered, which the Z. B. catch through a conical nozzle, and supplied centrifugal material approximated to it the direction and speed of the lighter components of the Grant centrifugal material in the centrifugal drum.

Hierdurch soll das Aufprallen des eingeführten Schleudergutes auf die Trommel verhindert und ein stetiger übergang der Geschwindigkeiten des zugeführten Schleudergutes herbeigeführt werden.This is intended to cause the impact of the introduced material to be thrown the drum prevents and a steady transition in the speeds of the feed Centrifuged material are brought about.

Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung dargestellt; es zeigen die neue Schleuder Abb. i im Längsschnitt, Abb. 2 im Querschnitt nach AB der Abb. i.An embodiment of the invention is shown in the drawing; it shows the new slingshot Fig. i in longitudinal section, Fig. 2 in cross section according to AB of Fig. i.

Der an sich. bekannte Aufbau der Schleuder ist der folgende: Auf der Hauptwelle a sind die Scheiben b und b1 befestigt, die mit der Schneckentrommel c verbunden sind; diese trägt die Schnecke a'. Die Hohlwelle f sitzt lose auf der Welle a. Sie steht durch die Stirnwände g und g1 mit der kegeligen Schleudertrommel h, die aus einem geschlossenen Mantel besteht, in fester Verbindung. In der am engeren Ende der Trommel k angeordneten Stirnwand g sind Austrittsöffnungen e für die schweren Bestandteile des Schleudergutes vorgesehen, während die entgegengesetzte Stirnwand 9l Austrittsöffnungen k für die leichteren Teile besitzt. Die Schnecke d erteilt den durch die Fliehkraft nach außen gedrängten schweren Bestandteilen eine Bewegung in der Richtung nach den Austrittsöffnungen. e hin: und die leichteren nach innen abgedrängten Stoffe bewegen. sich daher in entgegengesetzter Richtung. Das Schleudergut wird in die Schleuder durch den Stutzen L eingeleitet, der in einen feststehenden ringförmigen Verteiler! einmündet. Von hier aus, geht das Gut durch die Öffnungen. m in den, kegelig sich erweiternden Raum n über und tritt von dort durch Öffnungen o -der Stirnwand g in den kegelförmig erweiterten! Stutzen p. Das Schleudergut nimmt hierbei die Winkelgeschwindigkeit dieses umlaufenden Stutzens p an und wird am Austrittsende des kegeligen Stutzens p mit einer dem Durchmesser am Austritt entsprechenden Geschwindigkeit abgeschleudert, während die Flüssigkeit in der Schleudertrommel k eine höhere Umfangsgeschwindigkeit hat. Um nun das Aufprallen des abgeschleuderten Gutes auf die Flüssigkeit in der Trommel h zu verhüten, werden die Öffnungen r tler Schneckentrommel c durch Schaufeln g überdeckt, die das abgeschleuderte Gut auffangen und ablenken. Der Schaufelkranz besteht nach der Abbildung aus einem Winkelring g, der mit Rippen s versehen ist. Sie können aber auch in anderer Weise ausgebildet sein..The in itself. The known structure of the centrifuge is as follows: the disks b and b1 are attached to the main shaft a and are connected to the worm drum c; this carries the snail a '. The hollow shaft f sits loosely on the shaft a. Through the end walls g and g1 it is firmly connected to the conical centrifugal drum h, which consists of a closed jacket. In the end wall g arranged at the narrower end of the drum k, outlet openings e are provided for the heavy components of the material to be centrifuged, while the opposite end wall 91 has outlet openings k for the lighter parts. The screw d gives the heavy components pushed outwards by the centrifugal force a movement in the direction of the outlet openings. e towards: and move the lighter fabrics pushed inwards. therefore in the opposite direction. The material to be thrown is fed into the centrifuge through the nozzle L, which is fed into a fixed, ring-shaped distributor! joins. From here, the goods go through the openings. m into the conically widening space n and from there passes through openings o -the end wall g into the conically widened! Nozzle p. The material to be thrown here takes on the angular velocity of this circumferential nozzle p and is thrown off at the outlet end of the conical nozzle p at a speed corresponding to the diameter at the outlet, while the liquid in the centrifugal drum k has a higher peripheral speed. In order to prevent the material being thrown off from hitting the liquid in the drum h, the openings r tler screw drum c are covered by blades g, which catch and deflect the material being thrown off. According to the illustration, the blade ring consists of an angular ring g, which is provided with ribs s. But they can also be designed in other ways.

Die Wirkung der Schaufeln ist derart, daß sie das durch die öffnungen r tretende Gut auf die Umfangsgeschwindigkeit der Schnecke bringen. Ferner erhält das Schleudergut durch sie eine Ablenkung nach der Seite, wo die leichteren Bestandteile aus der Schleuder austreten. Da diese sich an der Innenseite des Schleudergutes in der Trommel befinden, wird mithin die Richtung und die Geschwindigkeit des eintretenden. Schleudergutes der Bewegung der in der Schleudertrommel befindlichen leichteren Fliissigkeit genähert, und somit werden Durchwirbelungen nach Möglichkeit verhindert.The action of the blades is such that they do this through the openings Bring the stepping material up to the circumferential speed of the screw. Also receives the material to be thrown through it a diversion to the side where the lighter constituents are step out of the slingshot. Since these are on the inside of the material to be centrifuged are located in the drum, therefore the direction and speed of the entering. Material to be centrifuged the movement of the lighter ones located in the centrifugal drum Liquid, and thus turbulence is prevented as far as possible.

Die Wirkung der Schaufeln ist eine ähnliche, als wenn das Schleudergut durch einen feststehenden Verteiler zugeführt würde.The action of the shovels is similar to that of the material being thrown would be fed through a fixed manifold.
