Abstract
Description
Die Erfindung betrifft eine Zweizylinder-Dickstoffpumpe mit einer in einem Beschickungsbehälter schwenkbar gelagerten, die Förderzylinder im Wechsel mit einer Förderleitung verbindenen Rohrweiche und einer an einer Wand des Beschikkungsbehälters angeflanschten, mindestens eine Förderschnekke aufweisenden, in Verbindung mit einem Fülltrichter stehenden Vorpreßeinrichtung.The invention relates to a two-cylinder thick matter pump with a swivel-mounted in a loading container, which alternately connects the delivery cylinders to a delivery line, and a pipe flange, which is flanged to a wall of the delivery container and has at least one feed screw and is connected to a filling funnel.
Dickstoffpumpen mit Vorpreßeinrichtungen sind bekannt (vgl. z.B. US-A 3 465 685). Die vorzugsweise aus ein- oder zweiwelligen Förderschnecken bestehenden Vorpreßeinrichtungen sind dort an einer Seite des die Rohrweiche aufweisenden Beschickungsbehälters angeflanscht, was sich bei ihrer Aufstellung oder bei ihrem Einbau in Räume mit vorgegebenen Abmessungen nachteilig auswirken kann.Thick matter pumps with pre-pressing devices are known (see e.g. US-A 3,465,685). The pre-pressing devices, which preferably consist of single-shaft or twin-shaft screw conveyors, are flanged there to one side of the feed container having the pipe switch, which can have a disadvantageous effect when they are installed or when they are installed in rooms with predetermined dimensions.
Der Erfindung liegt die Aufgabe zugrunde, eine Dickstoffpumpe der vorgenannten Art zu schaffen, die trotz der ausladenden Vorpreßeinrichtung bei ihrer Aufstellung oder bei ihrem Einbau den vorgegebenen Platzverhältnissen besser als bisher angepaßt werden kann.The invention has for its object to provide a slurry pump of the aforementioned type, which can be adapted to the given space better than before despite the protruding pre-pressing device when installing or installing it.
Zur Lösung dieser Aufgabe wird gemäß einer ersten Variante der Erfindung vorgeschlagen, daß der Beschickungsbehälter an mehreren Seiten abdeckbare Aussparungen aufweist, an die die Vorpreßeinrichtung wahlweise anflanschbar ist.To achieve this object, it is proposed according to a first variant of the invention that the loading container has cutouts which can be covered on several sides and to which the pre-pressing device can optionally be flanged.
Eine weitere Variante zur Lösung der vorstehenden Erfindungsaufgabe besteht darin, daß die Vorpreßeinrichtung an einem Teil des Beschickungsbehälters befestigt ist, der an dem die Rohrweiche aufnehmenden anderen Teil des Beschickungsbehälters in unterschiedlichen Ausrichtungen anflanschbar ist. Vorteilhafterweise ist dabei der die Vorpreßeinrichtung tragende Teil des Beschickungsbehälters über einen horizontalen Flansch mit dem die Rohrweiche aufnehmenden anderen Teil verbindbar, wobei der die Vorpreßeinrichtung tragende Teil zweckmäßig den unteren Teil des Beschickungsbehälters bildet. Wenn der die beiden Teile miteinander verbindende Flansch quadratisch ausgebildet ist, so kann die Vorpreßeinrichtung durch Drehung um jeweils 90° in unterschiedliche Ausrichtungen zu den Förderzylindern gebracht werden. Bei Verwendung eines Rundflansches ist auch jede beliebige Zwischenlage möglich.A further variant for solving the above object of the invention consists in that the pre-pressing device is fastened to a part of the loading container which is attached to the other part of the loading container receiving the pipe switch in different orientations can be flanged. Advantageously, the part of the loading container carrying the pre-pressing device can be connected via a horizontal flange to the other part receiving the pipe switch, the part carrying the pre-pressing device expediently forming the lower part of the loading container. If the flange connecting the two parts to one another is square, the pre-pressing device can be brought into different orientations to the feed cylinders by rotation through 90 ° in each case. When using a round flange, any intermediate layer is also possible.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Beschickungsbehälter eine abnehmbare oder abschwenkbare Deckplatte auf. Wenn dazuhin der die Rohrweiche aufnehmende Teil des Beschickungsbehälters einen oberen und einen unteren horizontalen Flansch mit jeweils gleichen Abmessungen aufweist, können der die Vorpreßeinrichtung tragende Teil und die Deckplatte wahlweise gegeneinander ausgetauscht werden. Eine unten liegende Deckplatte hätte dabei den Vorteil, daß der Beschickungsbehälter zu Reinigungszwecken leichter zugänglich ist und der Austausch von Verschleißteilen einfacher wird.According to a further advantageous embodiment of the invention, the loading container has a removable or swiveling cover plate. If, in addition, the part of the loading container which receives the pipe switch has an upper and a lower horizontal flange, each with the same dimensions, the part carrying the pre-pressing device and the cover plate can optionally be exchanged for one another. A cover plate located at the bottom would have the advantage that the loading container is more easily accessible for cleaning purposes and the replacement of wear parts becomes easier.

In die Rückwand des oberen Teils 11 des Beschickungsbehälters 1 münden zwei Förderzylinder 4 und 4′, deren Kolben 41 durch Hydrozylinder 42 im Gegentakt antreibbar sind. Die Förderzylinder sind über die schwenkbar angeordnete, ein S-förmiges Rohr aufweisende Rohrweiche 5 wechselweise mit der Förderleitung 6 verbindbar. Die Vorpreßeinrichtung 3 weist zwei miteinander kämmende Förderschnecken 31 und 31′ auf, die in einem Beschickungskanal angeordnet sind, der seinerseits über einen Fülltrichter 2 mit Fördergut beschickt wird. Die Vorpreßeinrichtung 3 mündet in den unteren Teil 12 des Beschickungsbehälters 1. Im Falle des in Fig. 1 gezeigten Ausführungsbeispiels ist die Flanschverbindung 13 zwischen den beiden Teilen 11 und 12 des Beschickungsbehälters quadratisch ausgebildet, so daß die Vorpreßeinrichtung durch Drehen um jeweils 90° in die in strichpunktierten Linien dargestellten Stellungen gebracht werden kann. Bei Verwendung eines Rundflansches 13 entsprechend Fig. 2 kann die Vorpreßeinrichtung in jeder beliebigen Richtung angebaut werden. Werden anstelle von Schrauben Klemmverbindungen am Flansch verwendet, dann ist sogar eine stufenlose Verdrehung der Vorpreßeinrichtung relativ zu den Pumpenzylinderns 4,4′ möglich.The thick matter pump shown in the drawing has a loading container 1, the
Grundsätzlich ist es möglich, bei dem Ausführungsbeispiel nach Fig. 1 am unteren Teil 12 des Beschickungsbehälters 1 mehrere Aussparungen 16 vorzusehen, die durch geeignete Deckel abdeckbar sind und an die die Vorpreßeinrichtung 3 wahlweise anflanschbar ist.In principle, it is possible in the exemplary embodiment according to FIG. 1 to provide a plurality of
