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. The accept of the suspension occurs from the hydrocyclone in the axial direction along the center line the separation chamber through an outlet for the accept, which either can be attached axially or tangentially to the separation chamber. 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 down from the separation cone and the accepts upwards the separation chamber removed.
Die hohe Geschwindigkeit und die abrasive Natur der Verunreinigungen innerhalb des Hydrozyklons können einen hohen Verschleiß des Abscheidekonus verursachen. Dieser kann 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. This can become so in the course of time progress that is an opening forms, which allows leakage of the suspension from the hydrocyclone or even a sudden Breakage of the cone due to the weakened wall sections causes. Therefore, the separation cone must be renewed in time.
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 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 to operate, in particular, worn parts should be easy to be replaced.
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, was besonders dann wesentlich billiger ist, wenn diese Teile aus Keramik hergestellt werden . Bekanntlich steigen die Herstellungskosten von Keramikteilen überproportional mit ihrer Größe. Außerdem hat die erfindungsgemäße Verbindungseinheit eine Doppelfunktion, da sie einen lösbaren Anschluss beider Teile des Abscheidekonus gestattet und außerdem eine Dichtfläche bildet, die den Anschluss an ein Rejektsystem vereinfacht. Es kann also mit Hilfe der Erfindung eine sehr ökonomische Behebung von Verschleißschäden an Hydrozyklonen erfolgen. So ist es möglich, das Unterteil separat zu tauschen. Das Oberteil hat eine mehrfach höhere Lebensdauer, wenn es aus dem gleichen Werkstoff wie das Unterteil besteht. Zur Anpassung an die Lebensdauer des Unterteils kann für das Oberteil ein kostengünstigerer Werkstoff gewählt werden, was wegen der Teilung des Abscheidekonus leicht möglich ist.Because of the separation of the separation cone, the items are smaller, which is much cheaper, especially when these parts are out Ceramics are produced. As is known, the production costs increase of ceramic parts disproportionately with her size. Besides, has the connection unit according to the invention a dual function, as it has a detachable connection of both parts allows the Abscheidekonus and also forms a sealing surface, which simplifies the connection to a reject system. So it can with the help of the invention a very economical remedy of wear damage to hydrocyclones respectively. So it is possible to exchange the lower part separately. The upper part has a multiple higher life, if it is made of the same material as the lower part. to Adjustment to the life of the lower part may be for the upper part a cheaper one Material to be selected which is easily possible because of the division of the separation cone.
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.
