Description

Die Erfindung betrifft eine Vorrichtung zur Behandlung von Flüssigmist in einer Grube, mit einer einseitig von einem Elektromotor antreibbaren Rührwelle, welche am freien, in die Grube einführbaren Ende mit einem freiliegenden Rührwerkzeug verbunden und in einem Hohlkörper geführt ist, über den dem Rührwfkzeug vom antriebsseitigen Ende Luft zuführbar ist, wobei die Ansaugöffnungen über den Hohlkörper direkt mit dem Rührwerkzeug in Verbindung stehen.The invention relates to a device for treating liquid manure in a pit, with one side by an electric motor driven agitator shaft, which at the free, insertable into the pit end with connected to an exposed stirring tool and guided in a hollow body over which the stirring tool air can be supplied from the drive-side end, the suction openings via the hollow body are in direct contact with the stirring tool.

In der Literaturstelle »Landtechnik«, Heft 2, Februar 1978, Seite 69, Abb. 6, ist eine derartige Vorrichtung beschrieben. Bei dieser bekannten Vorrichtung wird mittels des Rührwerkzeuges selbst über den die Rührwelle aufnehmenden Hohlkörper Luft angesaugt, w Bei der großen Länge der Rührwelle ergibt sich ein hoher Ansaugwiderstand, und damit ist die Luftzufuhr «um Rührwerkzeug nicht ausreichend, um die Gestankbildung beim Rührvorgang wirksam zu unterbinden. Das Ansaugen von Luft wird auch dadurch nicht π verbessert, daß das Rührwerkzeug am freien Ende der Rührwelle in einem Gehäuse nach Art eines Ventilators angeordnet ist, wie die BE-PS 5 06 758 zeigt.Such a device is described in the literature "Landtechnik", No. 2, February 1978, page 69, Fig. 6. In this known device, air is sucked in by means of the agitator itself through the hollow body that accommodates the agitator shaft. The length of the agitator shaft results in high suction resistance, and thus the air supply around the agitator is not sufficient to effectively prevent the formation of odor during the agitation process . The suction of air is also not improved π, that the stirring tool at the free end of the stirring shaft is arranged in a housing in the manner of a ventilator such as the BE-PS 5 06 758 shows.

Wie das DE-GM 19 26 074 zeigt, ist auch schon eine Vorrichtung bekannt, bei der auf einer Welle zwei Förderorgane angeordnet sind. Das obere, als Förderorgan ausgebildete Flügelrad läuft dabei in einem kammerartigen Gehäuse um und dient zur Änderung der Förderrichtung. Beide Förderorgane dieser bekann* ten Vorrichtung arbeiten jedoch auf ein und dasselbe Medium.As DE-GM 19 26 074 shows, there is already one Apparatus is known in which two conveying elements are arranged on a shaft. The upper one, as a funding body trained impeller rotates in a chamber-like housing and is used to change the conveying direction. However, both conveying organs of this known device work on one and the same thing Medium.

Es ist Aufgabe der Erfindung, eine Vorrichtung der eingangs erwähnten Art so weiterzubilden, daß mit einer reichlich angesaugten Luftmenge eine wirkungsvolle Belüftung bei der Umwälzung des Flüssigmistes gewährleistet ist.It is the object of the invention to develop a device of the type mentioned in such a way that with An abundant amount of sucked in air provides effective ventilation when circulating the liquid manure is guaranteed.

Dies wird nach der Erfindung dadurch erreicht, daß die Ansaugöffnungen in einer Ventilatorkammer angeordnet sind, in der ein auf der Rührwelle drehfest aufgebrachtes Flügelrad antreibbar istThis is achieved according to the invention in that the suction openings are arranged in a fan chamber are, in which an impeller mounted on the agitator shaft in a rotationally fixed manner can be driven

Durch die Verlagerung des Flügelrades ,'usammen mit dem Gehäuse auf das antriebsseitige Ende der Rührwelle wird ein praktisch widerstandsloses Ansaugen der Luft ermöglicht so daß viel Luft vorhanden ist. die unter Druck dem Rührwerkzeug über den Hohlkörper zugeführt wird.By moving the impeller, 'together with the housing on the drive-side end of the agitator shaft there is practically no resistance to suction allows the air so that there is a lot of air. the under pressure the stirring tool over the Hollow body is fed.

Dabei kann der Druck der im Bereich des Rührwerkzeuges aus dem Hohlkörper ausströmenden Luft dadurch noch erhöht werden, daß der Hohlkörper am freien Ende in Düsenöffnungen endetThe pressure in the area of the Stirring air flowing out of the hollow body can be increased by the fact that the hollow body ends in nozzle openings at the free end

Der konstruktive Aufbau kann zur Montagevereinfachung so ausgeführt sein, daß die Ventilkammer als getrennte Baueinheit ausgebildet ist die am antriebsseitigen Ende mit dem Hohlkörper verbunden ist.The structural design can be designed to simplify assembly so that the valve chamber as a separate structural unit is formed which is connected to the hollow body at the drive-side end.

Die Verbindung zum Elektromotor läßt sich in einfacher Weise dann so vornehmen, daß der Elektromotor mittels eines Traggerüstes starr mit der Ventilkammer verbunden ist und daß das Ende der Rührwelle direkt mit der Motorwelle des Elektromotors drehfest gekoppelt istThe connection to the electric motor can then be made in a simple manner so that the electric motor is rigidly connected to the valve chamber by means of a supporting structure and that the end of the The agitator shaft is directly rotatably coupled to the motor shaft of the electric motor

Mit dem Schalter 19 kann der Elektromotor 18 ein- und ausgeschaltet werden. Der mit dem Flügelrad 15 und der Ventilatorkammer 14 gebildete Ventilator 20 saugt bei der Drehbewegung der Rührwelle 10 einen ausreichend großen Luftstrom an, der über den Belüftungskanal 21 unter Druck direkt dem Rührwerkzeug 11 zugeführt wird. Dieser Belüftungskanal 21 wird durch den Zwischenraum gebildet, der sich /wischen der Rührwelle 10 und dem Hohlkörper 12 ergibt. Die Rührwelle 10 ist konzentrisch und im Abstand zum Hohlkörper 12 angeordnet, so daß sich ein im Querschnitt ringförmiger Belüftungskanal 21 ergibt. Am freien Ende ragt die Rührwelle 10 aus dem Hohlkörper 12 heraus, wobei zur Verbesserung der Belüftung der Hohlkörper 12 in Düsertöffnungen 22 endet.The agitator shaft 10 is rigidly connected to the motor shaft of an electric motor 18, which extends over the Support frame 17 is supported non-rotatably on the bearing extension 16 and thus the fan chamber 14. With the Switch 19, the electric motor 18 can be switched on and off. The one with the impeller 15 and the Fan 20 formed in the ventilator chamber 14 sucks in a sufficient amount during the rotary movement of the agitator shaft 10 large air flow, which is fed directly to the stirring tool 11 via the ventilation duct 21 under pressure will. This ventilation channel 21 is formed by the space that is / wipe the agitator shaft 10 and the hollow body 12 results. The agitator shaft 10 is concentric and at a distance from the hollow body 12 arranged, so that a ventilation duct 21 of annular cross-section results.
