Description

Hydrozyklon Es sind Vorrichtungen zum Trennen von festen Stoffen und Flüssigkeiten bekannt, bei denen die zu trennenden Suspensionen tangential unter Druck in einen Sid>zylinder eingeführt werden und dann infolge Zyklonwirkung in diesem und in dem anschließenden Siebkegel sich wendelförmig bis zum Austrag weiterbewegen. Am unteren Ende des Siebkegds ist gewöhnlich eine Staublende angeordnet. Rund um den Siebzylinder und/oder Siebkegel ist ein Gehäuse angeordnet, welches zwischen Siebaußenmantel und Gehäuseinnenwandung einen entsprechenden Raum bildet, in welchem die auszentrifugierte Flüssigkeit aufgefangen wird.Hydrocyclone There are devices for the separation of solids and Liquids known in which the suspensions to be separated are tangentially below Pressure can be introduced into a sid cylinder and then as a result of the cyclone effect in this and in the adjoining sieve cone spiral up to the discharge move on. A dust cover is usually arranged at the lower end of the Siebkegd. A housing is arranged around the screen cylinder and / or screen cone, which forms a corresponding space between the outer shell of the screen and the inner wall of the housing, in which the centrifuged liquid is collected.

Vorrichtungen dieser Art haben den Nachteil, daß die unter Druck zugeführten Suspensionen bald ihre kinetische Energie infolge der Reibung an der Siebwandung einbüßen. so daß schnell eine Verlangsamung der Strömung eintritt und so die Zyklonwirkung nicht mehr vorhanden ist. Dadurch wird die Gesamtlänge des Siebkegels nicht ausgenutzt, und der Wirkungsgrad des Hydrozyklons ist entsprechend gering. Devices of this type have the disadvantage that the under pressure supplied suspensions soon lose their kinetic energy as a result of the friction at the Lose sieve wall. so that the flow rapidly slows down and so the cyclone effect is no longer present. This will add to the total length of the Sieve cone not used, and the efficiency of the hydrocyclone is accordingly small amount.

Diese Nachteile werden eifindungsgemäß dadurch vermieden, daß im unteren Ende des Siebzylinders oder des Siebkegels eine in ihrer Höhe verstellbare Waschdüse angeordnet ist. Hierbei ist die Zuführung der Wasch- bzw. Aufschwemmittelmenge einstellbar. These disadvantages are avoided according to the invention in that the lower end of the screen cylinder or the screen cone an adjustable in height Washer nozzle is arranged. Here is the supply of the detergent or suspending agent amount adjustable.

Es wird dadurch erreicht, daß dem zu trennenden Gut an den Stellen des Siebes, wo eine stärkere Verlangsamung der Strömung eintritt, durch die Flüssigkeitsstrahlen der Waschdüse erneut kinetische Energie zugeführt wird und so die Zyklonwirkung erhalten bleibt.It is achieved that the material to be separated at the points of the sieve, where the flow slows down more, through the liquid jets kinetic energy is fed back to the washing nozzle and so the cyclone effect preserved.

Der Siebkegel oder -zylinder kann in seiner ganzen Länge ausgenutzt werden, und der Wirkungsgrad des Hydrozyklons erhöht sich.The sieve cone or cylinder can be used in its entire length and the efficiency of the hydrocyclone increases.

In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispiels näher erläutert. Es zeigt Abb. 1 einen Hydrozyklon, der mit einem Siebzylinder versehen ist, im Schnitt, Abb. 2 den gleichen Hydrozyklon in Richtung A-B geschnitten. In the drawing, the invention is based on an exemplary embodiment explained in more detail. Fig. 1 shows a hydrocyclone fitted with a sieve cylinder is, in section, Fig. 2, the same hydrocyclone cut in direction A-B.

Der Hydrozyklon besteht aus dem Eintrittsstutzen 1, der sich am Gehäuse 3 befindet. Im Gehäuse 3 ist der Siebzylinder 2 untergebracht. Anschließend an den Siebzylinder ist ein Konusteil 5 angeordnet. Am Unterteil des Gehäuses 3 ist der Austragstutzen 4 für die auszentrifugierte Flüssigkeit angebracht. Zentrisch im Hydrozyklon ist ein Druckrohr 8 angeordnet, das an seinem unteren Ende den Düsenkopf 9 trägt. Am unteren Ende des Konusteils 5 des Hydrozyklons ist der Austragstutzen 6 mit Staublende 7 angeordnet. The hydrocyclone consists of the inlet nozzle 1, which is located on the housing 3 is located. The screen cylinder 2 is accommodated in the housing 3. Subsequently to the A conical part 5 is arranged on the screen cylinder. On the lower part of the housing 3 is the Discharge nozzle 4 attached for the centrifuged liquid. Centric in Hydrocyclone a pressure pipe 8 is arranged, which at its lower end the nozzle head 9 wears. The discharge nozzle is at the lower end of the conical part 5 of the hydrocyclone 6 arranged with dust cover 7.

Die zu trennenden Suspensionen werden in Stutzen 1 in Pfeilrichtung unter Druck zugeführt und treten tangential in den Siebzylinder 2 ein. Infolge der Zyklonwirkung wird das zu trennende Medium an die Siebzylinderwandung gepreßt und fließt wendelförmig nach unten. In diesem Prozeß nimmt die kinetische Energie infolge der Reihung an der Wandung ab, und die Waschdüse 9 richtet ihre Flüssigkeitsstrahlen gegen das zu trennende Gut, so daß diesem erneut kinetische Energie zugeführt wird und der Trennungsprozeß seinen weiteren Fortgang nimmt. Dadurch wird die gesamte Siebzylinderlänge ausgenutzt, und die Trennung wird bis zu einem sehr hohen Grad getrieben. Die getrennte Flüssigkeit verläßt nun durch Stutzen 4 das Gehäuse 3, während die zurückbleibenden festen Stoffe über Konusteil 5, durch den Austrag 6, dem die Blende 7 vorgeschaltet ist, den Hydrozyklon verlassen. The suspensions to be separated are in nozzle 1 in the direction of the arrow supplied under pressure and enter the screen cylinder 2 tangentially. As a result of Cyclone effect, the medium to be separated is pressed against the screen cylinder wall and flows helically downwards. In this process the kinetic energy decreases as a result the row on the wall, and the washing nozzle 9 directs its liquid jets against the material to be separated, so that kinetic energy is supplied to it again and the process of separation continues. This will make the entire The length of the screen cylinder is used, and the separation is achieved to a very high degree driven. The separated liquid now leaves the housing 3 through nozzle 4, while the remaining solids via cone part 5, through discharge 6, which the diaphragm 7 is connected upstream, leave the hydrocyclone.
