Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert.The Invention will be explained below with reference to the drawing, for example.

Die einzige Figur der Zeichnung zeigt eine Querschnittsansicht durch eine Vorrichtung gemäß der Erfindung.The single figure of the drawing shows a cross-sectional view a device according to the invention.

In der Figur ist mit 6 ein Gehäuse bezeichnet, in welches über eine Zuführleitung 2 Flüssigkeit gelangen kann, die mit Feststoffen beladen ist.In the figure is with 6 denotes a housing, in which via a feed line 2 Liquid can reach, which is loaded with solids.

Im oberen Teil des Gehäuses 6 sind mit 40 Öffnungen bezeichnet, durch die die Flüssigkeit gepumpt wird und schließlich durch die Austrittsöffnung 12 wieder austritt.In the upper part of the housing 6 are with 40 Designates openings through which the liquid is pumped and finally through the outlet opening 12 exits again.

Oberhalb des Gehäuses 6 befindet sich ein zylindrisches Gehäuse 20, in dem ein Antriebsmotor 31 angeordnet ist. Es kann sich hierbei um einen Elektromotor, aber auch ebenso gut um einen Hydraulikmotor handeln. Die drehbar angetriebene Welle 30 geht aus dem zylindrischen Gehäuse 20 heraus und ragt in das Gehäuse 6 hinein. Im Gehäuse 6 ist auf der Welle 30 ein Messerrotor 13 angeordnet, der mit einer ortsfesten Siebplatte 15 mit einer Mehrzahl von Öffnungen 9 zusammenarbeitet. Wird die Welle 30 mit dem Messerrotor 13 durch den Antriebsmotor 31 gedreht, so kann der Messerrotor 13 die in der Strömung schwimmenden Feststoffe am Schneidsieb 15 erfassen und abtrennen. Dieser Vorgang ist von einer hinreichenden Axialkraft abhängig, die den Messerrotor 13 an das Schneidsieb 15 drückt. Diese axialdruckerzeugende Teile sind im Inneren des Zylinders 20 angeordnet und werden nachfolgend beschrieben.Above the case 6 there is a cylindrical housing 20 in which a drive motor 31 is arranged. This can be an electric motor, but also a hydraulic motor. The rotatably driven shaft 30 goes out of the cylindrical housing 20 out and protrudes into the case 6 into it. In the case 6 is on the wave 30 a knife rotor 13 arranged, with a stationary screen plate 15 with a plurality of openings 9 cooperates. Will the wave 30 with the knife rotor 13 through the drive motor 31 turned, so can the knife rotor 13 the solids floating in the flow on the cutting screen 15 capture and detach. This process is dependent on a sufficient axial force, the knife rotor 13 to the cutting screen 15 suppressed. These axial pressure generating parts are inside the cylinder 20 arranged and described below.

Der Motor 31 befindet sich nämlich nicht nur innerhalb des Zylinders 20, sondern auch innerhalb eines Kolbens 21, wobei dieser Kolben über ein Druckmittel 22 so beaufschlagt werden kann, dass der Messerrotor 13 hinreichend an das Schneidsieb 15 angedrückt wird.The motor 31 is not just inside the cylinder 20 but also inside a piston 21 , wherein this piston via a pressure medium 22 can be acted upon so that the knife rotor 13 Sufficient to the cutting wire 15 is pressed.

In der Figur sind die Lagerungen der Welle 30 und die Abdichtungen mit den üblichen zeichnerischen Mittel dargestellt. Auch ist der Kolben 21 nicht als Einfachzylinder, sondern als Doppelzylinder ausgebildet und dieser wiederum ist axial im zylindrischen Gehäuse 20 bewegbar, wobei auch dieses aus zwei Zylindern gebildet ist.In the figure, the bearings are the shaft 30 and the seals shown with the usual drawing means. Also, the piston 21 not designed as a single cylinder, but as a double cylinder and this in turn is axially in the cylindrical housing 20 movable, but this is formed of two cylinders.

Mit 50 ist eine Feder bezeichnet, die zwar axiale Bewegungen zwischen dem Kolben 21 und dem Zylinder 20 zulässt, nicht jedoch Verdrehbewegungen zwischen diesen Teilen.With 50 is a spring that indicates axial movements between the piston 21 and the cylinder 20 allows, but not twisting movements between these parts.
