Description

Elastische Dichtung für ununterbrochen arbeitende Schleudermaschinen mit herauf- und herabziehbarem Trommelmantel. Bei Schleudermaschinen ' für ununterbrochenen Betrieb mit herauf- und herabziehbarem Trommelmantel ist es bekannt, die Dichtung des Trormnelmantels am Boden und am Deckel der Schleuder mit Hilfe des den Trommelmantel bewegenden hydraulischen Druckes zu bewirken, um dem in der Schleuder wirkenden Zentrifugaldruck von 2o und mehr Atmosphären standzuhalten. Als Dichtungsflächen für Deckel und Boden der Schleuder hat man bisher federnde Ringe oder Lederstreifen, Hanfgeflechte u. dgl. verwendet. Diese Mittel halten jedoch bei dem auftretenden Schleuderdruck nicht dicht, weil die Lederdichtungen durch den Trommeldruck (hydraulischen Druck) beim Sichdazwischensetzen fester Teilchen des Schleudergutes bis über die Grenze ihrer Elastizität zusammengepreßt werden.Elastic seal for continuously working extractors with a drum shell that can be pulled up and down. For spin dryers' for uninterrupted It is known to operate with a drum shell that can be pulled up and down, the seal the drum shell on the bottom and on the lid of the centrifuge with the help of the drum shell moving hydraulic pressure to the effect in the centrifuge Withstand centrifugal pressure of 20 and more atmospheres. As sealing surfaces up to now, spring rings or leather strips have been used for the top and bottom of the slingshot, Hemp braids and the like are used. However, these funds hold on to when it occurs Centrifugal pressure not tight because the leather seals are affected by the drum pressure (hydraulic Pressure) when solid particles of the material to be thrown in between up to the Limit their elasticity are compressed.

Die Erfindung vermeidet diesen Nachteil, indem sie als Widerlager für den Trommelmantel am Boden oder am Deckel der Schleuder oder an beiden Stellen einen Dichtungsring aus elastischem Stoff, wie Gummi o. dgl., vorsieht vor. einer solchen Dicke bzw. Höhe (etwa 30 mm) bei entsprechender Breite, daß das elastische Mittel bei dem auf ihn ausgeübten hohen Preßdruck noch federt, so daß etwa zwischen den Dichtungsflächen befindliche feste Stoffteile in dieselben eingedrückt «erden und kein Hindernis für die Dichthaltung bilden. In der Zeichnung ist ein Äusführungsbeispiel einer derart ausgerüstegn Schleuder im Längsschnitt dargestellt.The invention avoids this disadvantage by providing a sealing ring made of elastic material, such as rubber or the like, as an abutment for the drum shell on the bottom or on the cover of the centrifuge or at both points. Such a thickness or height (about 30 mm) with a corresponding width that the elastic means still resiliently under the high pressure exerted on it, so that solid pieces of material located between the sealing surfaces are pressed into them and do not constitute an obstacle to the sealing . In the drawing, an exemplary embodiment of a slingshot equipped in this way is shown in longitudinal section.

Auf der sich im Betrieb dauernd drehenden Welle i ist ein Kopfstück 2 angeordnet, an welchem der Boden 3 der Schleuder befestigt ist. In dem Kopfstück 2 ist ein Ringzylinder 4 mit Ringkolben 5 untergebracht, der in bekannter Weise durch Luft- oder Flüssigkeitsdruck verschoben werden kann. Die Enden der Kolbenstangen io sind fest mit den Armen ii des Trommelmantels 12 verbunden, so daß letzterer herauf- und herabgezogen werden kann. Um das durch ein Zulaufrohr 13 in die Schleuder eintretende Gut schleudern zu können, muß der Trommelmantel i2 gegen den Deckel 14 und den Boden 3 der Schleuder abgedichtet werden. Dies geschieht nach der Erfindung, indem am Deckel und Boden je ein elastisches Mittel, wie Gummiring 15 bzw. 16 o. dgl., vorgesehen wird von einer solchen Höhe oder Dicke, daß der entsprechend breite Gummi selbst bei dem hohen, vom Trommelmantel auf ihn ausgeübten Preßdruck seine Elastizitätsgrenze noch nicht erreicht, sondern hierbei noch gut federt und somit etwa zwischen den Dichtungsflächen befindliche feste Stoffteile völlig elastisch umschließt und dadurch dicht hält.On the shaft i, which rotates continuously during operation, a head piece 2 is arranged, to which the bottom 3 of the slingshot is attached. In the head piece 2, a ring cylinder 4 with ring piston 5 is housed, which can be moved in a known manner by air or liquid pressure. The ends of the piston rods io are firmly connected to the arms ii of the drum shell 12 so that the latter can be pulled up and down. In order to be able to hurl the material entering the centrifuge through an inlet pipe 13, the drum shell i2 must be sealed against the cover 14 and the bottom 3 of the centrifuge. This is done according to the invention by an elastic means such as rubber ring 1 5 or 1 6 o pressure exerted on it has not yet reached its elasticity limit, but is still well resilient and thus completely elastically encloses solid material parts located between the sealing surfaces and thereby keeps them tight.
