Abstract

An assembly inoculates sludge with polymers. The sludge is subsequently de-watered in assembly such as a filter press chamber, screen press, excess sludge thickener or centrifuge. The de-watering assembly has a mixer pipe (13) with an outlet, and an inlet fed by a vortex chamber jets (6). The jet consists of a jet head with a constriction feeding to a polymer flow twister. The mixer pipe has a number of a number of turbulator vanes. A powered mixer unit has paddles or mixer blades (20) extending into the mixer pipe (1) downstream from the vortex chamber jets (6).

Description

Im Hauptpatent Nr. 197 41 797 ist eine Vorrichtung zum Impfen von Schlamm mit Polymeren zur anschließenden Entwässerung des Schlam­ mes beschrieben, welche gekennzeichnet ist durch ein mit Schlammein- und -auslauf versehenes Mischrohr, in das mindestens eine Wirbel­ kammerdüse mündet, die aus einem mit einer Verengung versehenen Düsenkopf und einem dahinter angeordneten Drallkörper für die Verwir­ belung des Polymers besteht, wobei im Mischrohr mehrere Leitbleche als Turbulenzgeber angeordnet sind.In main patent no. 197 41 797 is a device for vaccinating Sludge with polymers for subsequent dewatering of the sludge mes described, which is characterized by a with mud and -output mixing tube into which at least one vortex Chamber nozzle opens out of a narrowed Nozzle head and a swirl body arranged behind it for the entangling Belung of the polymer, with several baffles in the mixing tube Turbulence sensors are arranged.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die im Haupt­ patent beschriebene Vorrichtung zum Impfen von Schlamm mit Polymeren derart zu verbessern, daß durch eine nachfolgende Verwirbelung eine noch bessere Vermischung des geimpften Schlamms mit dem Polymer erzielt wird. The present invention has for its object the main Patent described device for inoculating sludge with polymers to improve such that a subsequent swirling even better mixing of the vaccinated sludge with the polymer is achieved.  

Zur Lösung der gestellten Aufgabe wird eine Vorrichtung der eingangs genannten Art vorgeschlagen, welche dadurch gekennzeichnet ist, daß an dem Mischrohr in Strömungsrichtung hinter den Wirbelkammerdüsen eine mit ihrem Paddeln oder Mischflügeln in das Mischrohr reichende, moto­ risch angetriebene Mischvorrichtung angeordnet ist.To solve the problem, a device of the beginning Proposed type, which is characterized in that the mixing tube in the direction of flow behind the swirl chamber nozzles with their paddles or mixing blades reaching into the mixing tube, moto rically driven mixing device is arranged.

Dadurch wird die Einimpfung des Schlamms durch die Verwirbelung des Schlamms mit dem Polymerimpfstoff weitgehend verbessert.This will inject the sludge through the swirling of the Sludge with the polymer vaccine largely improved.

Gemäß einer besonderen Ausführungsform besteht die Mischvorrichtung aus einem Elektromotor mit Lagerbuchse und Wellenachse, worauf zwei Paddel zur Verwirbelung angebracht sind, wobei der Winkel zwischen der Wellenachse und der Achse des Mischrohres ca. 450 beträgt. Dadurch wird eine Faserstoffumwicklung des eigentlichen Mischers weitgehend vermieden.According to a special embodiment, the mixing device from an electric motor with a bearing bush and shaft axis, followed by two Paddles are attached for swirling, the angle between the Shaft axis and the axis of the mixing tube is approximately 450. Thereby becomes a fiber wrapping of the actual mixer largely avoided.

Anhand der Zeichnung soll am Beispiel einer bevorzugten Ausführungs­ form die Vorrichtung gemäß der Erfindung näher erläutert werden.The drawing is based on the example of a preferred embodiment form the device according to the invention will be explained in more detail.

Die Figur der Zeichnung zeigt eine Seitenansicht mit Teilaufriß einer be­ sonderen Ausführungsform der Vorrichtung gemäß der Erfindung.The figure of the drawing shows a side view with partial elevation of a be special embodiment of the device according to the invention.

Wie sich aus der Figur ergibt, besteht die Vorrichtung gemäß der Erfin­ dung aus einem Mischrohr 13 mit zwei Flanschen 14, in das der zu imp­ fende Schlamm in Richtung des Pfeiles 15 eingeführt wird. Im unteren Be­ reich des Mischrohres 13 sind mehrere Wirbelkammerdüsen 6 gemäß dem Hauptpatent angeordnet, die in das Mischrohr reichen und mit abge­ winkelten Anschlußstücken 7 versehen sind.As can be seen from the figure, the device according to the inven tion consists of a mixing tube 13 with two flanges 14 , into which the mud to be imp in the direction of arrow 15 is inserted. In the lower loading area of the mixing tube 13 , a plurality of swirl chamber nozzles 6 are arranged according to the main patent, which reach into the mixing tube and are provided with angled connecting pieces 7 .

In Strömungsrichtung hinter den Wirbelkammerdüsen ist eine allgemein mit "16" bezeichnete Mischvorrichtung angeordnet. Die Mischvorrichtung 16 besteht aus einem Elektromotor 17 mit einer Lagerbuchse 18 und einer Wellenachse 19. Auf der Wellenachse 19 sind zwei Paddel 20 angeord­ net, die in das Innere des Mischrohres 13 reichen. Der Winkel zwischen der Wellenachse 19 und der Achse des Mischrohres 13 beträgt ca. 45°, um eine Faserstoffumwicklung der Paddel 20 zu vermeiden.In the direction of flow behind the vortex chamber nozzles, a mixing device, generally designated " 16 ", is arranged. The mixing device 16 consists of an electric motor 17 with a bearing bush 18 and a shaft axis 19 . On the shaft axis 19 , two paddles 20 are net angeord, which extend into the interior of the mixing tube 13 . The angle between the shaft axis 19 and the axis of the mixing tube 13 is approximately 45 ° in order to avoid a fiber wrapping around the paddles 20 .

Mit der Vorrichtung gemäß der Erfindung wird der wesentliche Vorteil er­ zielt, daß die mittels der Mischdüsen eingeimpften polymeren Impfstoffe innig mit dem Schlamm verwirbelt und vermischt werden.With the device according to the invention, the main advantage is aims that the polymeric vaccines inoculated by means of the mixing nozzles be whirled and mixed intimately with the mud.
