Abstract

In a separator whose centrifugal drum consists of two, in particular, conical parts (1, 23) connected to one another in rotationally symmetrical fashion, the conical parts (1, 3) form in the region of their greatest diameter a changeable annular gap (4) for the discharge of the solids. In order to connect the rotationally symmetrical parts (1, 2, 3) of the centrifugal drum in a particularly simple, space-saving and cost- effective manner, the centrifugal drum parts (1, 2, 3) are connected to one another by means of bolts (9) which are arranged distributed uniformly in the peripheral region in the circumferential direction. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Separator, dessen Zentrifugentrommel aus zwei miteinander rotationssymmetrisch verbundenen, insbesondere konischen Teilen besteht, die im Bereich ihres größeren Durchmessers einen veränderlichen Ringspalt für den Auslass der Feststoffe bilden.The invention relates to a separator, the centrifuge drum of which consists of two rotationally symmetrically connected, in particular conical parts, which form a variable annular gap for the outlet of the solids in the area of their larger diameter.

Ein Separator dieser Bauart ist beispielsweise aus der US-Patentschrift 3,823,868 bekannt. Bei diesem bekannten Separator sind Ober- und Unterteil der Zentrifugentrommel durch eine zentral angeordnete Tragsäule miteinander verbunden, an die im unteren Bereich die Antriebswelle angreift. Eine derartige, Ober-und Unterteil der Zentrifugentrommel verbindende Tragsäule ist im konstruktiven Aufbau verhältnismäßig kompliziert in Bezug auf die Befestigung der Trommeloberteile. Darüber hinaus treten im Betrieb dieses bekannten Separators an dem an der zentralenTragsäule befestigten Oberteil hohe Randspannungen auf, die zu einer elastischen Verformung des Oberteils führen. Aus diesem Grunde läßt sich dieses bekannte Konstruktionsprinzip nicht bei Separatoren mit verhältnismäßig großem Durchmesser anwenden, insbesondere dann nicht, wenn zur Erreichung eines guten Trennwirkungsgrades dazu auch noch hohe Drehzahlen gefordert werden. Ein weiterer Nachteil dieser bekannten Tragsäule besteht darin, daß sie einen verhältnismäßig großen Raum einnimmt und dadurch den Tellerraum für die zu trennenden Medien erheblich reduziert.A separator of this type is known, for example, from US Pat. No. 3,823,868. In this known separator, the upper and lower parts of the centrifuge drum are connected to one another by a centrally arranged support column, to which the drive shaft engages in the lower region. Such a support column connecting the upper and lower parts of the centrifuge drum is relatively complicated in terms of its construction in terms of fastening the upper drum parts. In addition, during operation of this known separator, high edge stresses occur on the upper part fastened to the central support column, which lead to an elastic deformation of the upper part. For this reason, this known design principle can not be applied to separators with a relatively large diameter, in particular not when to achieve a good separation efficiency and high speeds are also required. Another disadvantage of this known support column is that it takes up a relatively large space and thereby considerably reduces the plate space for the media to be separated.

Die Aufgabe der Erfindung besteht darin, die rotationssymmetrischen Teile der Zentrifugentrommel in besonders einfacher, raum- und kostensparender Weise miteinander zu verbinden. Diese Aufgabe wird dadurch gelöst, daß die Zentrifugentrommelteile durch Bolzen miteinander verbunden sind, die im peripheren Bereich gleichmäßig in Umfangsrichtung verteilt angeordnet sind. Auf diese Weise kann sehr vorteilhaft eine zentrale Verbindungssäule zwischen dem Ober- und Unterteil der Zentrifugentrommel entfallen, da die im Betrieb auftretenden Kräfte von den im peripheren Bereich gleichmäßig in Umfangsrichtung verteilten Bolzen aufgenommen werden. Diese erfindungsgemäßen Bolzen werden aufgrund ihrer außermittigen Anordnung im Betrieb des Separators praktisch nur auf Zug beansprucht und sie können daher, insbesondere bei Verwendung von hochwertigem Material, in Bezug auf ihren Duchmesser verhältnismäßig klein dimensioniert werden. Die Bolzen gemäß der Erfindung führen daher im Vergleich zu bekannten Separatoren mit zentraler Verbindungssäule zu keiner nennenswerten Reduzierung des Trennraumes im Separator, und sie können darüber hinaus auch besonders vorteilhaft bei Separatoren mit großen Durchmessern angewandt werden. Ein weiterer Vorteil dieser erfindungsgemäßen Bolzen besteht darin, daß sie im Vergleich zu den bisherigen bekannten Verbindungskonstruktionen mit wesentlich geringerem Material- und Kostenaufwand hergestellt werden können, und das Lösen und Verbinden der Zentrifugentrommelteile erheblich vereinfachen.The object of the invention is to connect the rotationally symmetrical parts of the centrifuge drum to one another in a particularly simple, space-saving and cost-saving manner. This object is achieved in that the centrifuge drum parts are connected to one another by bolts which are arranged distributed uniformly in the peripheral direction in the peripheral area. In this way, a central connecting column between the upper and lower part of the centrifuge drum can very advantageously be omitted, since the forces occurring during operation are absorbed by the bolts, which are distributed uniformly in the peripheral area in the peripheral area. Due to their eccentric arrangement during operation of the separator, these bolts according to the invention are practically only subjected to tension and they can therefore be dimensioned relatively small in relation to their diameter, especially when using high-quality material. The bolts according to the invention therefore do not lead to any appreciable reduction in the separation space in the separator compared to known separators with a central connecting column, and they can moreover also be used particularly advantageously in separators with large diameters. Another advantage of these bolts according to the invention is that they are compared to the previously known connection constructions can be manufactured with significantly less material and cost, and considerably simplify the loosening and connecting of the centrifuge drum parts.

Es sind zwar auch Separatoren bekannt, bei denen Ober-und Unterteil der Zentrifugentrommel durch eine Ringmutter miteinander verbunden werden. Eine derartige Konstruktion ermöglicht nur die Anordnung von einzelnen Austragsschlitzen im Bereich des größten Durchmessers. Ein solcher Separator ist daher in verfahrens- bzw. wirkungstechnischer Hinsicht wesentlich ungünstiger als ein Separator mit einem ringsum offenen Austragsschlitz (Ringspalt). Darüber hinaus ist hierbei die Anfertigung der verhältnismäßig großen Ringmutter nicht nur kostenaufwendig, sondern auch die Montage und Demontage der Zentrifugentrommel ist schwierig und nur mit besonderen Werkzeugen zu bewerkstelligen.Separators are also known in which the upper and lower parts of the centrifuge drum are connected to one another by a ring nut. Such a construction allows only the arrangement of individual discharge slots in the area of the largest diameter. Such a separator is therefore considerably less favorable in terms of process and action technology than a separator with a discharge slot (annular gap) which is open all round. In addition, the production of the relatively large ring nut is not only expensive, but also the assembly and disassembly of the centrifuge drum is difficult and can only be accomplished with special tools.

In weiterer Ausgestaltung der Erfindung sind die Bolzen im Bereich der resultierenden Axialkraft angeordnet. Auf diese Weise wird sehr vorteilhaft eine besonders gleichmäßige Aufteilung der im Betrieb des Separators auftretenden Kräfte auf die einzelnen Bolzen erreicht.In a further embodiment of the invention, the bolts are arranged in the region of the resulting axial force. In this way, a particularly uniform distribution of the forces occurring during operation of the separator between the individual bolts is very advantageously achieved.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Erläuterung eines in der Zeichnung schematisch im Längsschnitt dargestellten Ausführungsbeispieles.Further details, features and advantages of the invention result from the following explanation of an exemplary embodiment shown schematically in the drawing in longitudinal section.

Bei dem in der Zeichnung dargestellten Separator besteht die Zentrifugentrommel aus einem Unterteil 1 sowie einem konischen Oberteil 2. Mit dem Oberteil 2 ist ein konischer Ringteil 3 verbunden, der mit dem Unterteil 1 der Zentrifugentrommel einen Ringspalt 4 bildet. Im Unterteil 1 der Zentrifugentrommel ist im Mantelbereich eine an sich bekannte ringkolbenartige Verstelleinrichtung 5 vorgesehen, mit deren Hilfe der Ringspalt 4 geöffnet oder geschlossen wird. Ferner greift zentral am Unterteil 1 eine Antriebswelle 6 an, die mit einer in der Zeichnung .nicht näher dargestellten Antriebsvorrichtung in Verbindung steht. Zentral von oben ist ein Zulaufrohr 7 für die Trennmedien mit daran befestigtem Tellerpaket 8 eingeführt, das mit Abstand oberhalb des Bodens des Unterteils 1 endet. Das Zulaufrohr 7 mit dem Tellerpaket 8 ist hierbei mit dem Oberteil 2 der Zentrifugentrommel lösbar verbunden.In the separator shown in the drawing, the centrifuge drum consists of a lower part 1 and a conical upper part 2. A conical ring part 3 is connected to the upper part 2, which forms an annular gap 4 with the lower part 1 of the centrifuge drum. In the lower part 1 of the centrifuge drum, an annular piston-like adjusting device 5, known per se, is provided in the jacket area, with the aid of which the annular gap 4 is opened or closed. Furthermore, a drive shaft 6 acts centrally on the lower part 1 and is connected to a drive device not shown in the drawing. A feed pipe 7 for the separation media with plate pack 8 attached to it is inserted centrally from above and ends at a distance above the bottom of the lower part 1. The inlet pipe 7 with the plate pack 8 is detachably connected to the upper part 2 of the centrifuge drum.

Gemäß der Erfindung sind die Zentrifugentrommelteile, nämlich das Unterteil 1, Oberteil 2 und Ringteil 3 miteinander durch Bolzen 9 verbunden,die in ihrem oberen Bereich mit einem Gewinde 10 und einer entsprechenden Schraubenmutter 11 versehen sind. Diese Bolzen 9 sind sehr vorteilhaft im peripheren Bereich gleichmäßig in Umfangsrichtung verteilt angeordnet, und zwar im Bereich der resultierenden Axialkraft, die im Fliehkraftfeld zwischen dem Innenradius des Trennmediums und dem Außenradius der Zentrifugentrommel liegt. Auf diese Weise wird sehr vorteilhaft eine besonders gleichmäßige Übertragung der im Betrieb des Separators auftretenden Zugkräfte auf die einzelnen Bolzen 9 bewirkt. Die aus hochwertigem Werkstoff bestehenden Bolzen 9 können daher einen verhältnismäßig kleinen Durchmesser aufweisen, so daß durch sie keine nennenswerte volumetrische Reduzierung des Trennraumes erfolgt. Die Bolzen 9 können ferner sehr vorteilhaft mit dem Unterteil 1 der Zentrifugentrommel durch Preßsitz fest verbunden werden, wodurch sich für die Montage oder auch Demontage des Oberteils 2 eine erhebliche Vereinfachung ergibt. Hierzu brauchen nämlich nur die Schraubenmuttern 11 abgeschraubt werden und das Oberteil 2 der Zentrifugentrommel kann in einfacher Weise mit dem daran befestigten Zulaufrohr 7 und Tellerpaket 8 nach oben hin herausgezogen und ebenso von oben wieder eingesetzt werden. Diese sehr einfache Montage und Demontage des Oberteils 2 der Zentrifugentrommel wird durch die über den äußeren Rand des Tellerpaketes 8 hinausgehende, zwischen dem Oberteil 2 und dem Ringteil 3 liegende Trennfuge 12 erreicht.According to the invention, the centrifuge drum parts, namely the lower part 1, upper part 2 and ring part 3 are connected to one another by bolts 9 which are provided in their upper region with a thread 10 and a corresponding screw nut 11. These bolts 9 are very advantageously evenly distributed in the peripheral area in the circumferential direction, specifically in the area of the resulting axial force which lies in the centrifugal force field between the inner radius of the separating medium and the outer radius of the centrifuge drum. In this way, a particularly uniform transmission of the tensile forces occurring during the operation of the separator to the individual bolts 9 is very advantageously effected. The bolts 9 made of high-quality material can therefore have a relatively small diameter, so that there is no significant volumetric reduction in the separation space. The bolts 9 can also very advantageously be firmly connected to the lower part 1 of the centrifuge drum by a press fit, which results in a considerable simplification for the assembly or disassembly of the upper part 2. For this purpose, only the screw nuts 11 need to be unscrewed and the upper part 2 of the centrifuge drum can be pulled out with the feed pipe 7 and plate pack 8 attached to it in a simple manner and can also be reinserted from above. This very simple assembly and disassembly of the upper part 2 of the centrifuge drum is achieved by the parting line 12 which extends beyond the outer edge of the plate pack 8 and lies between the upper part 2 and the ring part 3.

Die Zufuhr der zu trennenden Medien, zum Beispiel eines Feststoff-Flüssigkeitsgemisches, erfolgt in an sich bekannter Weise in Pfeilrichtung 13 von oben durch das zentrale Zulaufrohr 7 in den Trennraum der Zentrifugentrommel, während der Austrag der festen Phase durch den Ringspalt 4 in Pfeilrichtung 14 und die flüssige Phase in Pfeilrichtung 15 nach oben hin erfolgt. Die konstruktive Ausbildung des Separators gemäß der Erfindung bringt im Vergleich zu bekannten Separatoren nicht nur eine erhebliche Vereinfachung hinsichtlich des konstruktiven Aufbaus und der Wartung mit sich, sondern sie ermöglicht auch - unter Beibehaltung der zur Erreichung eines optimalen Trennwirkungsgrades erforderlichen hohen Drehzahlen - den Bau von Separatoren mit bedeutend größerem Durchmesser bzw. Trennraumvolumen und entsprechend höherer Durchsatzleistung als dies bisher der Fall war.The media to be separated, for example a solid / liquid mixture, are supplied in a manner known per se in the direction of the arrow 13 from above through the central feed pipe 7 into the separation space of the centrifuge drum, while the solid phase is discharged through the annular gap 4 in the direction of the arrow 14 and the liquid phase takes place in the direction of arrow 15 upwards. The structural design of the separator according to the invention not only brings about a considerable simplification in terms of structural design and maintenance in comparison with known separators, but it also enables the construction of separators while maintaining the high speeds required to achieve optimum separation efficiency with a significantly larger diameter or separation volume and correspondingly higher throughput than was previously the case.
