Description
Auf dem Grubenboden gelagerte, mit drehbaren Rührstutzen versehene Pumpe für Dickstoffe Es ist schon vorgeschlagen worden, auf der auf dem Grubenboden ruhenden Scihleuderpumpe einen drehbaren Stutzen anzuordnen, der von oben her durch einen Steckschlüssel o. dgl. um 3600 gedreht werden kann und der in einer Stellung das Pumpengehäuse mit der Förderleitung verbindet, während er in anderen Stellungen das geförderte Gut zu Rührzwecken unmitelbar in die Grube oder in ein besonderes auf dem Grubenboden verlagertes Rohrnetz leitet.Mounted on the bottom of the pit with rotating agitator nozzles Pump for thick matter It has already been proposed on the pit floor dormant Scihleuderpumpe to arrange a rotatable nozzle, which from above through a socket wrench or the like. Can be turned by 3600 and in one position the pump housing connects to the delivery line while he is in other positions the conveyed material for stirring purposes directly in the pit or in a special one pipe network relocated to the pit floor.
Nach der vorliegenden Erfindung ist eine Abänderung dahin getroffen, daß die Förderleitung mit der Pumpe durch den Drehstutzen nicht unmittelbar, sondern mittelbar in Wirkungsverbindung gebracht wird. Diese Abänderung ist baulich so durchgebildet, daß der Drehstutzen sich nicht mehr wie bei dem älteren Vorschlage gegen die Mündung des unten abgekrümmten Förderrohres .anlegt, sondern daß er sich in einer Stellung gegen -eine am Förderrohr außen angebrachte Fläche richtet; dadurch wird die Förderung durch den Stutzen in die Grube hinein unmöglich gemacht, und die Förderung erfolgt durch das Steigrohr; in anderen Stellungen des Drehstutzens, wenn durch diesen die Flüssigkeit zu Rührzwecken in die Grube ausgespritzt wird, reicht die Leistung der Schleuderpumpe nicht aus, um außerdem noch durch die Steigleitung zu fördern. According to the present invention, a modification is made to that the delivery line with the pump through the rotary connector not directly, but is indirectly brought into effect connection. This modification is structured in such a way that that the rotary connector is no longer against the mouth as in the older proposal of the bent conveyor pipe .anetzt, but that it is in one position directed against a surface attached to the outside of the conveyor pipe; thereby the promotion made impossible by the nozzle into the pit, and the promotion takes place through the riser pipe; in other positions of the rotary connector, if through this the If liquid is sprayed into the pit for stirring purposes, the output is sufficient The centrifugal pump does not turn off in order to also pump through the riser.
Die Pumpenausführung nach dem älteren Vorschlag wird durch die neue Ausblildungsart in mehrfacher Hinsicht verbessert. The pump design based on the older proposal is replaced by the new Training type improved in several ways.
Zunächst kann das Steigrohr einfacher und damit billiger ausgebildet werden. First of all, the riser pipe can be made simpler and therefore cheaper will.
Ein besonderer Vorteil besteht darin, daß die bei dem älteren Vorschlage erforderliche Unterbrechung des Steigrohres, die zu Undichtigkeiten Anlaß gab, in. Fortfall kommt. A particular advantage is that the older proposals necessary interruption of the riser pipe, which gave rise to leaks, in. Failure comes.
Weiter ;braucht die Mündung des Drehstutzens nicht mehr der Öffnimgsform des Steigrohres. angepaßt zu werden; man ist in der Formgebung jetzt frei und kann den Drehstutzen mit einer düsen- oder strahlrohrartigen Öffnung ausstatten, um so die Rührwirkung zu verbessern. Next; the mouth of the rotary connector no longer needs the opening shape of the riser pipe. to be adjusted; one is now free to shape and can equip the rotary connector with a nozzle-like or jet pipe-like opening, so as to to improve the stirring effect.
Trotz der erzielten Vorteile ist die grundlegende Einfachheit der älteren Pumpe und damit auch ihre Billigkeit in der Ausführung beibehalten, und ebenso ermöglicht die neue Einrichtung auch den unmittelbaren Anschluß des Drehstutzens an auf dem Grubenboden verteilte Sonderrohre, durch weiche die Rührflüssigkeit an verschiedene von der Pumpe entfernte Stellen der Grube geleitet werden kann. Despite the benefits obtained, the basic simplicity is the older pump and thus also its cheapness in execution retained, and the new device also enables the swivel connector to be connected directly on special pipes distributed on the bottom of the pit through which the stirring liquid softens can be routed to various places in the pit remote from the pump.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. The drawing shows an embodiment of the subject matter of the invention shown.
