Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den gebräuchlichen Kreiselpumpen für Jauche kommt es vor, daß infolge von Verstopfung durch in die Jauche geratene Düngerteile Störungen eintreten. Dieser Ubelstand soll bei der vorliegenden Erfindung vermieden werden durch innen an der Gehäusewandung von deren mittlerem Teil aus gegen deren Umfang hin laufende Kanäle, welche in entgegengesetztem Sinne gebogen sind wie die ίο Schaufeln des Schaufelrades.With the common centrifugal pumps for liquid manure, it happens that as a result of clogging disturbances can occur due to fertilizer parts that have got into the liquid manure. This evil is to be avoided in the present invention by the inside of the housing wall from the central part of the canals running towards their circumference, which are curved in the opposite direction to the ίο blades of the paddle wheel.

Die beiliegende Zeichnung stellt eine beispielsweise Ausführungsform des Erfindungsgegenstandes dar, und zwar zeigt: The accompanying drawing represents an example Embodiment of the subject matter of the invention, namely shows:

Fig. ι einen Achsialschnitt durch diese, währendFig. Ι an axial section through this, while

Fig. 2 einen Schnitt normal zur Achse darstellt. Fig. 2 shows a section normal to the axis.

In der an den Einlaufstutzen 4 für die Jauche anliegenden Gehäusewandung 2 sind vier Kaao näle 1 vorgesehen, welche von dem mittleren Teil der Gehäusewandung 2 gegen deren Peripherie verlaufen und in entgegengesetztem Sinne gebogen sind wie die Schaufeln des Schaufelrades.In the housing wall 2 lying against the inlet connection 4 for the liquid manure, there are four Kaao channels 1 provided, which from the central part of the housing wall 2 against the periphery run and are curved in the opposite sense as the blades of the Paddle wheel.

Die zufällig mit der Jauche in das Gehäuse eintretenden Düngerteile werden durch die Schaufeln des Schaufelrades durch die Kanäle ι gegen die Peripherie des Gehäuses und schließlich in den Auslaufstutzen 5 gejagt, soThe fertilizer parts that happen to enter the housing with the liquid manure are caused by the The blades of the impeller through the channels ι against the periphery of the housing and finally chased into the outlet nozzle 5, so

daß ein Verstopfen im Gehäuse vermieden wird. 'that clogging in the housing is avoided. '

Es können weniger oder mehr als vier Kanäle vorgesehen sein, und es könnten dieselben sich bis in den Einlaufstutzen erstrecken (um Herumreißen von Mist zu verhindern).There could be fewer or more than four channels, and the same could be extend into the inlet nozzle (to prevent manure from being pulled around).

Die Breite der Kanäle könnte so groß gewählt sein, daß der zwischen zwei benachbarten Kanälen liegende Teil der Gehäusewandung eine Rippe bildet.The width of the channels could be chosen so large that that between two adjacent Channels lying part of the housing wall forms a rib.
