Abstract
Description
Die Erfindung bezieht sich auf einen Hydrozyklon gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a hydrocyclone according to the preamble of the claim 1.
Hydrozyklone werden bei der Reinigung von Suspensionen verwendet, mit besonderer Anwendung bei Flüssigkeit-Faser-Suspensionen, wie z.B. beim Herstellen von Zellstoff und Papierprodukten. Die Flüssigkeit-Faser-Suspension, die Verunreinigungen enthält, tritt in den Hydrozyklon unter Druck durch einen tangentialen Einlass ein und wird dabei in Rotation versetzt. Die Rotationsbewegung der Suspension verursacht ein Abtrennen der Verunreinigungen von den Papier- oder Zellstofffasern. Die Verunreinigungen, wie Steine, Sand, mineralische Füllstoffe, Metallpartikel und andere schwere Störstoffe werden auf Grund der Zentrifugalkraft an die Wand der Trennkammer geführt und an dieser entlang zum Abscheidekonus transportiert. Da sich der konische Bereich in axialer Flussrichtung der Suspension verjüngt, vergrößert sich die Zentrifugalkraft und verursacht eine Konzentration der Verunreinigungen entlang der inneren Wand bis zum Auslass für den Schwerschmutz. Der Schwerschmutz verlässt den Hydrozyklon eventuell mit einigen annehmbaren Fasern am engsten Querschnitt des Abscheidekonus'. Der Gutstoff der Suspension tritt aus dem Hydrozyklon in axialer Richtung entlang der Mittellinie der Trennkammer durch einen Auslass für den Gutstoff aus, der entweder axial oder tangential an der Trennkammer angebracht sein kann. In den meisten Fällen werden Hydrozyklone der hier betrachteten Art mit senkrecht stehender Mittellinie betrieben. Dann ist die Trennkammer oberhalb des Abscheidekonus', die Schwerteile werden unten aus, dem Abscheidekonus und der Gutstoff nach oben aus der Trennkammer abgeführt.hydrocyclones are used in the purification of suspensions, with special Application in liquid-fiber suspensions, such as. in the manufacture of pulp and paper products. The Liquid-fiber suspension, contains the impurities, enters the hydrocyclone under pressure through a tangential inlet and is set in rotation. The rotational movement of the suspension causes a separation of the impurities from the paper or Cellulose fibers. The impurities, such as stones, sand, mineral fillers, Metal particles and other heavy impurities are due to the Centrifugal force led to the wall of the separation chamber and along this to Abscheidekonus transported. As the conical area in the axial flow direction the suspension tapers, increases the centrifugal force and causes a concentration of impurities along the inner wall to the outlet for the heavy dirt. The heavy dirt leaves possibly the hydrocyclone closest to some acceptable fibers Cross section of the separation cone '. Of the Acceptance of the suspension exits the hydrocyclone in the axial direction along the center line of the separation chamber through an outlet for the accept, attached either axially or tangentially to the separation chamber can be. In most cases will be Hydrocyclones of the type considered here with vertical center line operated. Then the separation chamber above the Abscheidekonus', the heavy parts bottom out, the separation cone and the accepts up discharged from the separation chamber.
Die hohe Geschwindigkeit und die abrasive Natur der Verunreinigungen innerhalb des Hydrozyklons können einen hohen Verschleiß des Abscheidekonus' verursachen. Auch wenn das Keramik-Material an sich einen hohen Abriebwiderstand hat, kann der Verschleiß im Laufe der Zeit derartig fortschreiten, dass sich eine Öffnung bildet, die eine Leckage der Suspension aus dem Hydrozyklon ermöglicht oder gar einen plötzlichen Bruch des Konus' auf Grund der geschwächten Wandabschnitte hervorruft. Daher muss der Abscheidekonus rechtzeitig erneuert werden.The high speed and the abrasive nature of the contaminants within the hydrocyclone can a high wear of the Cause separation cone. Even if the ceramic material In itself has a high abrasion resistance, the wear in the course the time so progressively that an opening forms, which is a leakage of the Suspension from the hydrocyclone allows or even a sudden Fracture of the cone on the ground the weakened Causes wall sections. Therefore, the separation cone must be timely to be renewed.
Die Schwerteilbelastung ist besonders hoch, wenn die Suspension aus Altpapier hergestellt wird.The Heavy burden is particularly high when the suspension is off Waste paper is produced.
Der Erfindung liegt die Aufgabe zu Grunde, einen Hydrozyklon zu schaffen, der auch bei hohem Verschleiß wirtschaftlich zu betreiben ist, insbesondere durch kostengünstige Verschleißteile. Auch sollen verschlissene Teile einfach zu ersetzen sein.Of the Invention is based on the object to provide a hydrocyclone, which is economical even at high wear is to operate, in particular by low-cost wearing parts. Also, worn parts should be easy to replace.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 genannten Merkmale bereits gelöst.These The object is achieved by the mentioned in the characterizing part of claim 1 Features already solved.
Wegen der Aufteilung des Abscheidekonus' sind die Einzelteile kleiner. Bekanntlich steigen die Herstellungskosten von Keramikteilen überproportional mit ihrer Größe. Es kann also mit Hilfe der Erfindung eine sehr ökonomische Behebung von Verschleißschäden an Hydrozyklonen erfolgen. Außerdem ist es möglich, das Unterteil, das erfahrungsgemäß zuerst verschlissen ist, separat zu tauschen. Das Oberteil hat eine mehrfach höhere Lebensdauer.Because of the division of the separating cone ', the items are smaller. generally known increase the production cost of ceramic parts disproportionately with her size. It can So with the help of the invention, a very economical remedy of wear damage to hydrocyclones respectively. Furthermore Is it possible, the lower part, which experience shows first worn out, to be exchanged separately. The top has a multiple higher Lifespan.
Die Erfindung und ihre Vorteile werden erläutert an Hand von Zeichnungen. Dabei zeigen:The The invention and its advantages are explained with reference to drawings. Showing:
Zur einfacheren Beschreibung des Erfindungsgegenstandes ist der Hydrozyklon in typischer senkrechter Arbeitsposition gezeigt und so beschrieben. Bekanntlich ist es aber ohne weiteres möglich und gelegentlich aus Platzgründen erforderlich, Hydrozyklone in waagerechter oder schräger Form anzuordnen, was die Anwendbarkeit der Erfindung nicht einschränkt.to a simpler description of the subject invention is the hydrocyclone shown in typical vertical working position and so described. As is known, however, it is readily possible and occasionally off space limitations required, hydrocyclones in horizontal or oblique shape to arrange, which does not limit the applicability of the invention.
