Abstract

Apparatus for conveying sewage or waste water by means of a rotatable displacement pump positioned within a housing. A cutting device is positioned at a water inlet for cutting solid materials that are part of the waste water to reduce their size in order for the materials to be able to pass through the pump. The pump is an eccentric worm-gear pump and is driven by a motor drive shaft that also drives the rotatable portion of the cutting device. The apparatus has a compact design and provides a high suction capacity, and a conveying capability that is independent of the supply resistance, so that a small diameter pump outlet pipe can be provided for the sewage.

Description

Die vorliegende Erfindung betrifft eine Abwasserfördereinrichtung gemäss Oberbegriff des Anspruches 1.The present invention relates to a wastewater conveying device according to the preamble of claim 1.

Es ist bekannt, für die Förderung von Abwässern Exzenterschneckenpumpen, die zu den rotierenden Verdrängerpumpen zu zählen sind, zu verwenden. Exzenterschneckenpumpen haben den Vorteil, dass deren Fördermenge bei konstanter Drehzahl des Drehantriebes praktisch unabhängig vom Förderwiderstand in der Druckleitung ist, so dass letztere optimal für ihren jeweiligen Einsatz dimensioniert werden kann. Exzenterschneckenpumpen haben den weiteren Vorteil, dass hohe Drücke erzielbar sind. Doch können Exzenterschneckenpumpen grosse Feststoffe nicht bewältigen. Es ist daher schon vorgeschlagen worden, der Exzenterschneckenpumpe einen Zerkieinerer vorzuschalten, der alle durch die Exzenterschneckenpumpe angesaugten Teile zerkleinert - (siehe den Artikel von H. Putz "Abwasserhebeanlagen" in der Fachzeitschrift für Sanitär, Heizung, Klima, Heft 23, 35. Jahrgang, 1. Ausgabe, Dezember 1980, Berlin).It is known to use progressing cavity pumps, which belong to the rotating positive displacement pumps, for the conveyance of waste water. Eccentric screw pumps have the advantage that their flow rate at the constant speed of the rotary drive is practically independent of the flow resistance in the pressure line, so that the latter can be optimally dimensioned for its respective application. Eccentric screw pumps have the further advantage that high pressures can be achieved. However, eccentric screw pumps cannot handle large solids. It has therefore already been proposed to connect the eccentric screw pump upstream of a shredder, which will shred all parts sucked in by the eccentric screw pump - (see the article by H. Putz "Abwasserhebeanlagen" in the specialist journal for sanitary, heating, air conditioning, issue 23, 35th year, 1st edition, December 1980, Berlin).

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Abwasserfördereinrichtung der eingangsgenannten Art von kompaktem und einfachem Aufbau zu schaffen.The present invention has for its object to provide a wastewater pumping device of the type mentioned compact and simple structure.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Dabei ist die Verdrängerpumpe vorzugsweise eine Exzenterschneckenpumpe, wobei bei einer bevorzugten Ausführungsform die Exzenterschneckenpumpe und die Zerkleinerungsvorrichtung an entgegengesetzten Enden des gemeinsamen Drehantriebes mit letzterem verbunden sind. Demgegenüber kann es auch vorteilhaft sein, die Zerkleinerungsvorrichtung zwischen der Exzenterschneckenpumpe und dem gemeinsamen Drehantrieb anzuordnen.The displacement pump is preferably an eccentric screw pump, in a preferred embodiment the eccentric screw pump and the comminution device being connected to the latter at opposite ends of the common rotary drive. In contrast, it can also be advantageous to arrange the comminution device between the eccentric screw pump and the common rotary drive.

Im folgenden werden anhand der Zeichnung Ausführungsbeispiele des Erfindungsgegenstandes näher erläutert.Exemplary embodiments of the subject matter of the invention are explained in more detail below with reference to the drawing.

Die beiden Figuren zeigen rein schematisch in Seitenansicht und teilweise im Längsschnitt zwei Ausführungsformen einer Abwasserfördereinrichtung.The two figures show purely schematically in side view and partly in longitudinal section two embodiments of a wastewater conveying device.

Die in Fig. 1 dargestellte Ausführungsform ist für die vertikale Anordnung in einem Abwasserschacht vorgesehen, so dass die zentrale Hauptwelle 1, die den Rotor 2 eines Elektromotors 3 trägt, vertikal verläuft. Der Elektromotor 3 ist als Tauchmotor ausgeführt und entsprechend mit einem den Stator 4 umschliessenden Kühlmantel 5 versehen. Der Elektromotor hat zwei einander gegenüberliegende Wellenenden 7, 8, die sich durch je ein endseitiges Lager 9, 10 des Elektromotors 3 hindurcherstrecken sowie durch je einen zwei Wellendichtungen 12, 13 umschliessenden endseitigen Gehäuseteil 15, 16. In diesen endseitigen Gehäuseteilen des Elektromotors 3 können zusätzliche Wellenlager eingeschlossen sein.The embodiment shown in FIG. 1 is intended for vertical arrangement in a sewage shaft, so that the central main shaft 1, which carries the rotor 2 of an electric motor 3, runs vertically. The electric motor 3 is designed as a submersible motor and is accordingly provided with a cooling jacket 5 surrounding the stator 4. The electric motor has two mutually opposite shaft ends 7, 8, each of which extends through an end bearing 9, 10 of the electric motor 3 and through an end housing part 15, 16, which encloses two shaft seals 12, 13, and additional ones can be fitted in these end housing parts of the electric motor 3 Shaft bearings included.

Am unteren endseitigen Gehäuseteil 16 ist das Gehäuse 18 einer Zerkleinerungsvorrichtung 19 über eine Flanschverbindung 20 befestigt. Der untere Teil dieses Gehäuses 18 geht in den trichterförmigen Ansaugstutzen 21 über, der mit Abstand über dem nicht dargestellten Boden eines Abwasserschachtes angeordnet ist. Die Zerkleinerungsvorrichtung 19 hat einen am unteren Wellenende 8 befestigten Schneidkopf 22, an dessen Umfang mehrere Schneidmesser 23 im Winkel zur Längsrichtung der Einrichtung befestigt sind. Diese umlaufenden Schneidmesser 23 arbeiten zur Zerkleinerung von Feststoffbestandteilen des Abwassers mit einem feststehenden, den Schneidkopf 22 umschliessenden Schneidgegenring 25 zusammen, der am Gehäuse 18 der Zerkleinerungsvorrichtung 19 befestigt ist. Das Abwasser durchströmt den Spalt 26 zwischen dem Schneidkopf 22 und dem Schneidgegenring 25, in dem das Zerschneiden und/oder Zerreissen der Feststoffbestandteile, wie z.B. von Papier, Textilien u.a., erfolgt. An der der Zuströmöffnung 27 abgekehrten Seite des Schneidkopfes 22 ist eine Abweisscheibe 28 befestigt, die sich bis nahe an die Innenwand des Gehäuses 18 der Zerkleinerungsvorrichtung 19 heranerstreckt und an die Oberkante 29 eines seitlichen Anschlussstutzens 30 für die Saugleitung 31 angrenzt, um das Abwasser nach Passieren des Schneidkopfes 22 zu dem Anschlussstutzen 30 hin abzuweisen. Eine zweite Wasserabweisscheibe 33 ist hinter dieser Abweisscheibe 28 innerhalb des endseitigen Gehäuseteils 16 auf dem Wellenende 8 befestigt.The housing 18 of a comminution device 19 is fastened to the lower end-side housing part 16 via a flange connection 20. The lower part of this housing 18 merges into the funnel-shaped suction nozzle 21, which is arranged at a distance above the bottom of a sewage shaft, not shown. The shredding device 19 has a cutting head 22 attached to the lower shaft end 8, on the circumference of which a plurality of cutting knives 23 are attached at an angle to the longitudinal direction of the device. These rotating cutting knives 23 work together with a stationary cutting counter ring 25, which surrounds the cutting head 22 and is attached to the housing 18 of the shredding device 19, for shredding solid constituents of the waste water. The waste water flows through the gap 26 between the cutting head 22 and the cutting counter ring 25, in which the cutting and / or tearing of the solid components, such as e.g. paper, textiles, etc. On the side of the cutting head 22 facing away from the inflow opening 27, a deflecting disc 28 is fastened, which extends close to the inner wall of the housing 18 of the comminution device 19 and adjoins the upper edge 29 of a lateral connecting piece 30 for the suction line 31, in order to prevent the waste water from passing through the cutting head 22 to reject the connection piece 30. A second water deflector disk 33 is fastened behind this deflector disk 28 on the shaft end 8 within the end housing part 16.

Am oberen endseitigen Gehäuseteil 15 ist die Exzenterschneckenpumpe 35 befestigt. Der Saugstutzen 36 dieser Pumpe, an der die zu der Zerkleinerungsvorrichtung 19 führende Saugleitung 31 angeschlossen ist, befindet sich seitlich an einem eine Kuppelstange 38 einschliessenden Gehäuseteil 39, an den in axialer Richtung das Statorgehäuse 40 der Exzenterschneckenpumpe 35 angrenzt. Die Kuppelstange 38 stellt über zwei wasserdicht gekapselte Kugelgelenke 41, 42 die Verbindung zwischen dem Wellenende 7 des Elektromotors 3 und dem schraubenförmig gewuhdenen Pumpenrotor 44 dar, der in der Zeichnung nur hälftig dargestellt ist. Hinsichtlich der Funktionsweise dieser Exzenterschneckenpumpe 35 wird auf die Fachliteratur verwiesen, beispielsweise auf das Buch "Die Pumpen" von Fuchslocker/Schulz, Springer-Verlag, 11. Auflage.The eccentric screw pump 35 is fastened to the upper end-side housing part 15. The suction port 36 of this pump, to which the suction line 31 leading to the comminution device 19 is connected, is located laterally on a housing part 39 which includes a coupling rod 38 and on which the stator housing 40 of the eccentric screw pump 35 adjoins in the axial direction. The coupling rod 38 via two watertight encapsulated ball joints 41, 42 represents the connection between the shaft end 7 of the electric motor 3 and the helically pumped pump rotor 44, which is only shown in half in the drawing. Regarding the functional this eccentric screw pump 35 is referred to the specialist literature, for example to the book "Die Pumpen" by Fuchslocker / Schulz, Springer-Verlag, 11th edition.

Die in Fig. 2 gezeigte Abwasserfördereinrichtung, welche ebenfalls vertikal angeordnet ist, ist der Ausführungsform gemäss Fig. 1 im Aufbau sehr ähnlich, unterscheidet sich jedoch von letzterer in der anderen Anordnung der Zerkleinerungsvorrichtung und der Exzenterschneckenpumpe.The wastewater conveying device shown in FIG. 2, which is also arranged vertically, is very similar in construction to the embodiment according to FIG. 1, but differs from the latter in the other arrangement of the comminution device and the eccentric screw pump.
