Description

Die Erfindung betrifft eine drehbare Separatortrommel mit einer vertikalen Drehachse nach dem Oberbegriff des Anspruchs 1.The invention relates to a rotatable Separatortrommel with a vertical axis of rotation according to the preamble of claim 1.

Eine jeweils gattungsgemäße Separatortrommel ist beispielsweise aus der DE 19519693 C1 oder der DE 10 2006 047478 A1 bekannt, wobei das tellerartige Bauteil der Verteilerfuß ist, der an seiner Unterseite eine im wesentlichen konische und damit insofern beispielhaft tellerartige Form aufweist.A respective generic separator drum is for example from the DE 19519693 C1 or the DE 10 2006 047478 A1 known, wherein the plate-like component is the distributor foot, which has on its underside a substantially conical and therefore insofar exemplary plate-like shape.

Zum Stand der Technik werden noch die DE 18 96 480 U , die DE 14 32 794 A , die US 26 45 415 A , die DE 10 2006 047 478 A1 und die DE 30 42 948 A1 genannt.The state of the art still the DE 18 96 480 U , the DE 14 32 794 A , the US 26 45 415 A , the DE 10 2006 047 478 A1 and the DE 30 42 948 A1 called.

Die Verteiler dienen dazu, das zu verarbeitende Produkt von einem Zulaufrohr durch Strömungskanäle - hier auch Verteilerkanäle genannt - in die Trommel zu leiten. Diese Konstruktion hat sich an sich bewährt. Problematisch ist allerdings, dass die Strömungskanäle insbesondere bei der Verarbeitung von Produkten, die abrasiv wirkende Feststoffe enthalten, einem erhöhten Verschleiß ausgesetzt sind, der sich nachteilig auf die Lebensdauer des Verteilers auswirken kann. Analoge Probleme können an anderen Elementen der Separatortrommel, so insbesondere an tellerartigen Bauelementen wie Scheidetellern, an Trommelteilen oder an Blechen, welche an die Innenflächen der Trommelteile angebracht sind, auftreten. Beispielsweise an Scheideteller geht die Strömung von außen nach innen, sonst von innen nach außen.The distributors serve to direct the product to be processed from an inlet pipe through flow channels - also called distribution channels - into the drum. This construction has proven itself. The problem, however, is that the flow channels, especially in the processing of products containing abrasive solids, are exposed to increased wear, which can adversely affect the life of the distributor. Similar problems can occur on other elements of the separator drum, in particular on plate-like components such as separator plates, on drum parts or on plates which are attached to the inner surfaces of the drum parts. For example, on divider plate, the flow goes from outside to inside, otherwise from the inside out.

Die Erfindung hat die Aufgabe, dieses Problem zu verringern.The invention has the object to reduce this problem.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1.The invention solves this problem by the subject matter of claim 1.

Besonders bevorzugt ist das an wenigstens einer Fläche tellerartige Bauteil ein Fußabschnitt eines Verteilers, der mit der Trommel drehfest verbunden ist, wobei der Fußabschnitt mit wenigstens einem oder mehreren der Strömungskanäle versehen ist, die sich winklig zur Drehachse vorzugsweise radial nach außen erstrecken, wobei in dem Bereich zwischen der Eintrittsöffnung und der Austrittsöffnung in dem wenigstens einen Strömungskanal wenigstens eines der Stauwehre angeordnet ist.Particularly preferably, the plate-like component on at least one surface is a foot portion of a distributor, which is rotatably connected to the drum, wherein the foot portion is provided with at least one or more of the flow channels, which extend at an angle to the axis of rotation, preferably radially outwardly, wherein in the Region between the inlet opening and the outlet opening in which at least one flow channel at least one of the weirs is arranged.

Das Stauwehr ist derart ausgestaltet, dass sich im Betrieb bei der Verarbeitung eines feststoffhaltigen Produktes (in Strömungsrichtung von innen nach außen) vor dem Stauwehr eine Feststoffanhäufung ausbildet. Diese Materialanhäufung(en) wirken im Betrieb des Separators wie ein Verschleißschutz für das tellerartige Teil, insbesondere für die Verteilerfußabdeckung. Die Aufgabe der Erfindung wird derart mit einfachen Mitteln umfassend gelöst.The weir is designed in such a way that during operation of the processing of a solids-containing product (in the direction of flow from inside to outside) in front of the weir, an accumulation of solids is formed. This material accumulation (s) act in the operation of the separator as a wear protection for the plate-like part, in particular for the Verteilerfußabdeckung.

An den zentrischen Eintrittsrohrabschnitt 4 schließen im Fußabschnitt 5 umfangsverteilt winklig, vorzugsweise spitzwinklig oder rechtwinklig zur Drehachse radial nach außen erstreckende Strömungskanäle 6 an. Die Strömungskanäle 6 verlaufen im Bezug auf die Drehachse hier schräg nach unten, sie könnten aber auch spitzwinklig vom Zulaufrohrabschnitt 4 schräg nach oben gerichtet sein.At the central inlet pipe section 4 close in the foot section 5 circumferentially distributed at an angle, preferably at an acute angle or at right angles to the axis of rotation radially outwardly extending flow channels 6 at. The flow channels 6 extend in relation to the axis of rotation here obliquely downwards, but they could also be directed at an acute angle from the feed pipe section 4 obliquely upward.

In der Trommel 1 ist ein Trenntellerstapel 7 aus Trennteller 8 angeordnet. Ableitungen 9, 10 für wenigstens eine oder mehrere flüssige und vorzugsweise eine feste Phase dienen zur Ableitung der getrennten und/oder geklärten Phasen aus der Trommel 1. Der Verteiler 4 ist mit geeigneten Mitteln an der Trommel 1 befestigt. Der Produktfluss ist mit Pfeilen angedeutet.In the drum 1, a separation plate stack 7 is arranged from separation plate 8. Discharges 9, 10 for at least one or more liquid and preferably a solid phase are used to derive the separated and / or clarified phases from the drum 1. The distributor 4 is attached by suitable means to the drum 1. The product flow is indicated by arrows.

Die Strömungskanäle 6 erstrecken sich in dem Verteilerfuß 5 von Eintrittsöffnungen 11 in die Strömungskanäle bis zu Austrittsöffnungen 12 aus den Strömungskanälen 6 in den Innenraum der Schleudertrommel.The flow channels 6 extend in the distributor foot 5 from inlet openings 11 into the flow channels up to outlet openings 12 from the flow channels 6 into the interior of the centrifugal drum.

Nach oben hin werden die Strömungskanäle von einer hier konischen Verteilerfußabdeckung 13 abgedeckt. Seitlich bzw. in Umfangsrichtung werden die Strömungskanäle 6 von Wandabschnitten 14 begrenzt. Jedenfalls an der Unterseite ist die Verteilerfußabdeckung tellerartig ausgebildet.Towards the top, the flow channels are covered by a conical distributor foot cover 13. Laterally or in the circumferential direction, the flow channels 6 are bounded by wall sections 14. In any case, at the bottom of the Verteilerfußabdeckung is plate-like.

In dem Bereich zwischen den Eintrittsöffnungen 11 und den Austrittsöffnungen 12 sind in den Strömungskanälen, von denen Fig. 3 einen nach Art eines Blickes unter den Verteilerfuß 13 veranschaulicht, mehrere Stauwehre 15 angeordnet, welche den Querschnitt des Strömungskanals in diesem Bereich verengen.In the area between the inlet openings 11 and the outlet openings 12 are in the flow channels, of which Fig. 3 one illustrated in the manner of a glance under the Verteilerfuß 13, a plurality of weirs 15 are arranged, which narrow the cross-section of the flow channel in this area.

Vorzugsweise sind die Stauwehre 15 als Rippen ausgebildet. Diese Rippen 15 sind vorzugsweise im Übergangsbereich jeweils zwischen einer der Seitenwände 14 und der Verteilerfußabdeckung 13 angeordnet bzw. ausgebildet, und zwar insbesondere in dem Übergangsbereich zwischen der im Betrieb in Drehrichtung U hinteren Wandabschnitt 14 und der Verteilerfußabdeckung 13. In Umfangsrichtung sind die Strömungskanäle 6 hier durch die Wandabschnitte 14 voneinander getrennt.Preferably, the weirs 15 are formed as ribs. These ribs 15 are preferably arranged or formed in the transition region between one of the side walls 14 and the Verteilerfußabdeckung 13, in particular in the transition region between the rear in operation U wall portion 14 and the Verteilerfußabdeckung 13. In the circumferential direction, the flow channels 6 here separated from each other by the wall sections 14.

Besonders bevorzugt weisen die Rippen in diesem Bereich einen dreiecksförmigen Abschnitt 16 auf, der sich an der Unterseite der Verteilerfußabdeckung 13 über einen Teil der Umfangslänge des Strömungskanals 6 erstreckt und dann in einen Stegabschnitt 17 übergeht. Der im Wesentlichen dreieckige Abschnitt 16 kann im Bereich seiner Grundseite 18 auch beispielsweise eine Bogenform aufweisen. Die Höhe H der Abschnitte 15 und 16 beträgt wenigstens 2 mm oder mehr. Der Abschnitt 16 erstreckt sich vorzugsweise bis zur in Umfangsrichtung nächsten Seitenwand 14. Vorzugsweise werden mehr als drei Wehre in jedem Strömungskanal 6 verteilt. Ziel ist es, dass sich möglichst mit der Zeit eine durchgehende verschleißschützende Beschichtung an der Unterseite der Verteilerfußabdeckung 13 ausbildet.Particularly preferably, the ribs in this area a triangular portion 16 which extends on the underside of the Verteilerfußabdeckung 13 over part of the circumferential length of the flow channel 6 and then merges into a web portion 17.
