Feststehender zylindrischer Abwasserrechen mit mindestens einer Zerkleinerungseinrichtung für das Rechengut Es sind feststehende zylindrische Abwasserrechen mit mindestens einer Zerkleinerungseinrichtung für das Rechengut bekannt, die aus einer parallel zur Zylinderachse angeordneten, um ihre Achse rotierenden und über den Umfang des Abwasserrechens bewegbaren Welle besteht, deren Spurlager mit einem Kammträger fest verbunden ist und deren über ihren Umfang verteilte Schneidezähne mit den Schlitzen zwischen den horizontal liegenden Rechenstäben und zwischen den Messern des Kammträgers in Eingriff stehen. Bei diesen Abwasserrechen war keine Vorkehrung für das Verteilen und Abführen des mit dem Kamm zerkleinerten Rechengutes getroffen, so daßes sich um den Umfang des Rechens herum ansammelte und zu Verstopfungen und Betriebsstörungen Anlaß ,o ab.Fixed cylindrical wastewater rake with at least one shredding device for the screenings There are fixed cylindrical wastewater screens with at least a shredding device for the screenings known, which consists of a parallel arranged to the cylinder axis, rotating around its axis and over the circumference of the Wastewater rake movable shaft is made, whose thrust bearings are fixed to a comb carrier is connected and its incisors distributed over its circumference with the slots between the horizontally lying rake bars and between the knives of the comb carrier are engaged. With these sewage rakes there was no provision for distribution and removal of the screenings crushed with the comb, so that it is accumulated around the perimeter of the rake, causing blockages and malfunctions Occasion, o from.
2 Durch die Erfindung wird ein Abwasserrechen geschaffen, bei welchem für die Ableitung des zerkleinerten Rechengutes Sorge getragen ist, so daß solche Verstopfungen und Betriebsstörungen ausgeschlossen sind. Dies wird gemäß der Erfindung dadurch erreicht, daß der Kammträger einen Flansch aufweist, der, im Drehsinn der Welle gesehen, diese unter Freilassung eines Zwischenraumes umschließt und bis nahe an die Stäbe des Abwasserrechens reicht. In diesem Zwischenraum wird das teilweise zerkleinerte Rechengut aufgefangen und nach weiterer Zerkleinerung durch die Rechenstäbe hindurch abgeleitet, ohne daß sich Teile dieses Rechengutes erneut an anderen Stellen des Abwasserrechens festsetzen können. Die Ableitung des Rechengutes wird unterstützt durch das einströmende Schmutzwasser, welches in eine Quirlbewegung versetzt wird und damit sämtliche zerkleinerten Teile mitnimmt. Die Messer sollen ferner einstellbar angeordnet sein ', so daß sie auf Grund der besonderen Verhältnisse und Erfordernisse in ihrer Lage zu der Zerkleinerungsvorrichtung geändert werden können. 2 The invention provides a wastewater rake is provided, wherein for the discharge of the comminuted screenings care is taken so that such clogging and malfunctioning are excluded. This is achieved according to the invention in that the comb carrier has a flange which, viewed in the direction of rotation of the shaft, encloses the shaft leaving a gap and extends to close to the bars of the waste water rake. The partially crushed screenings are caught in this gap and, after further crushing, are diverted through the screen rods without parts of this screenings being able to get stuck again at other points of the wastewater rake. The drainage of the screenings is supported by the inflowing dirty water, which is set in a whirling motion and thus takes all the crushed parts with it. The knives should also be arranged to be adjustable so that their position in relation to the comminuting device can be changed on the basis of the special conditions and requirements.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.
Fig. 1 zeigt einen Abwasserrechen in Seitenansicht., teilweise in senkrechtem Schnitt; Fig. 2 ist ein waagerechter Schnitt nach der Linie 11-II der Fig. 1; Fig. 3 ist ein waagerechter Schnitt nach der Linie 111-111 der Fig. 1. Fig. 1 shows a waste water rake in side view, partially in vertical section; Fig. 2 is a horizontal section on the line 11-II of Fig. 1; FIG. 3 is a horizontal section along line 111-111 of FIG. 1.
Der feststehende zylindrische Rechen 1 ist auf einer Grundplatte 2 befestigt. Der Abwasserrechen wird mittels zweier Ständer 3 eingebaut in die Senkgrube eines Kanalschachtsystems. In der Achse des Rechens 1 ist ein Drehzapfen 4 mittels Schraubenmuttern 5 an dem Rechen befestigt. Eine Hülse 8 ist über Kugellager 6 und 7 drehbar um den Drehzapfen 4 angeordnet. Mittels Schrauben 11 ist ein Tragring 9 an einem Flansch 10 der Hülse 8 befestigt. Das Kugellager 6 ist über einen Einstellring 13 an der Unterseite der Hülse 8 mittels Schrauben 12 befestigt, wobei Preßölschmierungsringe 14 zwischen dem Einstellring 13 und dem Drehzapfen 4 vorgesehen sind. Die oberen Seite des Tragringes 9 ist durch eine Platte 16 mittels Schraubenbolzen 15 abgeschlossen. Die Platte 16 ist mit drei nach oben vorstehenden Teilen 17 versehen. Durch Anschluß des zum Abwasserrechen konzentrischen Teiles 17 an die Antriebswelle eines beispielsweise nicht dargestellten Elektroinotors', wird der Tragring 9 in eine rotierende Bewegung um den feststehenden Drehzapfen 4 versetzt. Infolgedessen dreht sich der Tragring 9 in bezug auf den stehenden Rechen 1. The fixed cylindrical rake 1 is attached to a base plate 2. The sewage rake is installed in the cesspool of a sewer system by means of two stands 3. In the axis of the rake 1 , a pivot 4 is fastened to the rake by means of screw nuts 5. A sleeve 8 is rotatably arranged around the pivot 4 via ball bearings 6 and 7. A support ring 9 is fastened to a flange 10 of the sleeve 8 by means of screws 11 . The ball bearing 6 is fastened via an adjusting ring 13 to the underside of the sleeve 8 by means of screws 12, pressure oil lubrication rings 14 being provided between the adjusting ring 13 and the pivot 4. The upper side of the support ring 9 is closed by a plate 16 by means of screw bolts 15 . The plate 16 is provided with three parts 17 protruding upwards. By connecting the part 17 , which is concentric with the waste water rake, to the drive shaft of an electric motor, not shown, for example, the support ring 9 is set in a rotating movement around the stationary pivot pin 4. As a result, the support ring 9 rotates with respect to the stationary rake 1.
An dem Tragring 9 sind zwei Kämme 18 (s. auch Fig. 3) befestigt. Jeder dieser Kämme 18 besteht aus einem kurvenförmigen Kammträger 19, dessen oberes Ende fest mit dem Tragring 9 verbunden ist, während an dem unteren Ende des Kammträgers 19 eine Lagerplatte 21 mit Hilfe von Schrauben 20 fest angebracht ist.Two combs 18 (see also FIG. 3) are attached to the support ring 9. Each of these combs 18 consists of a curved comb carrier 19, the upper end of which is firmly connected to the support ring 9 , while a bearing plate 21 is firmly attached to the lower end of the comb carrier 19 with the aid of screws 20.
Der Kammträger 19 ist mit waagerecht liegenden Schlitzen versehen, in welche Messer22, die in ihrer Längsrichtung einstellbar sind, angeordnet sind. Diese Messer 22 sind in ihrer eingestellten Lage mittels C Stahlbolzen 23 befestigt. Der Kammträger 19 weist einen Flansch 24 auf, der bis nahe an die Stäbe des Rechens 1 reicht. In dem Zwischenraum 25 zwischen Flansch 24 und Rechen 1 wird das zerkleinerte Rechengut zurückgehalten, bis es nach weiterer Zerkleinerung durch die Rechenstäbe hindurch mit dem Abwasser zu dem Hauptgully oder -abzugsschacht abgeleitet wird.The comb carrier 19 is provided with horizontally lying slots in which knives 22, which are adjustable in their longitudinal direction, are arranged. These knives 22 are fastened in their set position by means of C steel bolts 23. The comb carrier 19 has a flange 24 which extends close to the bars of the rake 1 . In the space 25 between the flange 24 and the rake 1 , the crushed screenings are retained until, after further crushing, they are discharged through the screen rods with the sewage to the main gully or drainage shaft.
Mittels einer Schraubenmutter26 ist eine Spindel 27 auf der Lagerplatte 21 befestigt. Die Zerkleinerungseinrichtung selbst besteht aus einem dickwandigen, hohlen Zylinder29, durch den innen eine hohle Welle30 geführt ist. Diese Welle30 ist mit dem Zylinder29 durch einen Flansch31 und ein abnehmbares Abschlußglied32 verbunden und um die Spinde127 mittels eines KugeHagers28 drehbar gelagert. A spindle 27 is fastened to the bearing plate 21 by means of a screw nut 26. The shredding device itself consists of a thick-walled, hollow cylinder29 through which a hollow shaft30 is guided on the inside. This shaft 30 is connected to the cylinder 29 by a flange 31 and a removable end member 32 and is rotatably supported around the spindle 127 by means of a KugeHager28.
Das Abschlußglied 32 setzt sich nach oben in eine Spindel 36 fort, welche mit Hilfe von Kugellagern 37 drehbar in einer an dem Tragring 9 mittels eines Flansches befestigten Hülse 39 gelagert ist.The end member 32 continues upward into a spindle 36 which is rotatably supported with the aid of ball bearings 37 in a sleeve 39 fastened to the support ring 9 by means of a flange.
Die hohle Welle 30 trägt eine Mehrzahl von durch die Wandung des Zylinders 29 geführten Zähnen 42. Die angeschärften Enden 43 der Zähne 42 greifen zwischen die Messer 22 der Kämme 18. Die übereinander angeordneten Zähne sind gleichmäßig gegeneinander versetzt, so daß jeder der Zähne nacheinander zwischen zwei Stäben des Rechens 1 und zwischen den entsprechenden Messern 22 der Kämme 18 hindurchgeht. Der Antrieb der Zerkleinerungsvorrichtung erfolgt von einem auf dem Drehzapfen 4 angeordneten Ketten- oder Zahnrad 48 über Ketten 49 und auf den Spindeln 36 angeordnete Ketten- oder Zahnräder 44.The hollow shaft 30 carries a plurality of teeth 42 guided through the wall of the cylinder 29. The sharpened ends 43 of the teeth 42 engage between the knives 22 of the combs 18. The superposed teeth are evenly offset from one another so that each of the teeth is successively between two bars of the rake 1 and between the corresponding knives 22 of the combs 18 passes. The comminution device is driven by a chain or toothed wheel 48 arranged on the pivot 4 via chains 49 and chain or toothed wheels 44 arranged on the spindles 36.
