Description
Die Erfindung betrifft eine Befüllvorrichtung von nichthomogenen Flüssigkeiten, wie Gülle, Jauche, Klärschlamm oder Fäkalien.The invention relates to a filling device for non-homogeneous liquids, such as liquid manure, liquid manure, sewage sludge or faeces.
Bei der Gülleausbringung stellt in vielen Fällen die Befüllung des Güllewagens einen Engpass dar, weil es an leistungsfähigen und vor allem an flexibel einsetzbaren Befüllvorrichtungen fehlt.In many cases, the filling of the slurry tanker is a bottleneck when spreading liquid manure because there is a lack of efficient and, above all, flexible filling devices.
Im einfachsten Fall ist am Güllewagen ein Kompressor oder eine Pumpe angebaut, die über einen Saugschlauch die Gülle aus der Grube in den Fasswagen fördert. Um den Saugvorgang zu beschleunigen sind aus der Praxis zusätzliche Befüllvorrichtungen mit einem Saugrad bekannt, die in der Saugleitung zwischen Kompressor/Pumpe und Grube zwischengeschaltet werden. Sobald der Volumenstrom durch den Kompressor hergestellt ist, übernimmt dann die zwischengeschaltete Befüllvorrichtung die weitere Förderung. Dabei können maximale Druck- bzw. Saugleistungen von bis zu 7000 l/h erreicht werden, sodass auch große Fasswägen in wenigen Minuten befüllt werden können. Dabei kann unter Umständen sogar auf den Einsatz von fasseigenen Kompressoren und Pumpen ganz verzichtet werden.In the simplest case, a compressor or a pump is attached to the slurry tanker, which conveys the slurry from the pit into the drum tanker via a suction hose. In order to accelerate the suction process, additional filling devices with a suction wheel are known from practice, which are interposed in the suction line between the compressor / pump and the pit. As soon as the volume flow through the compressor is established, the intermediate filling device then takes over the further conveyance. Maximum pressure and suction capacities of up to 7000 l / h can be achieved, so that even large drum carts can be filled in a few minutes. Under certain circumstances, the use of barrel compressors and pumps can even be dispensed with entirely.

Der Erfindung liegt nun die Aufgabe zugrunde eine Befüllvorrichtung zur Saugförderung von nichthomogenen Flüssigkeiten, wie Gülle, Jauche, Klärschlamm oder Fäkalien, in ihrer Effektivität und Leistungsfähigkeit durch eine einfache Verstellbarkeit des Schneidmessers zu verbessern.The invention is based on the object of improving the effectiveness and performance of a filling device for the suction delivery of non-homogeneous liquids, such as liquid manure, liquid manure, sewage sludge or faeces, by simply adjusting the cutting knife.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of claim 1.
Die erfindungsgemäße Befüllvorrichtung zur Saugförderung von nichthomogenen Flüssigkeiten, wie Gülle, Jauche, Klärschlamm oder Fäkalien, weist ein Gehäuse mit einem Ansaugstutzen und einem Abführstutzen sowie ein im Gehäuse angeordnetes und auf einer antreibbaren Welle gehaltertes Saugrad auf, wobei ein mit einer Gegenschneide zusammenwirkendes Schneidmesser im Bereich des Ansaugstutzens vorgesehen ist, wobei die Welle mit einem Ende bis in den Ansaugstutzen hineinreicht und das Schneidmesser drehfest an diesem Ende der Welle befestigt ist und die Welle zur Einstellung des Schnittspaltes zwischen Gegenschneide und Schneidmesser axial verschiebbar im Gehäuse gelagert ist. Die Verstellbarkeit des Schneidmessers wird durch eine koaxial um die Welle angeordnete Verstellhülse ermöglicht, wobei eine Drehung der Verstellhülse eine Verschiebung der Welle in ihrer axialen Richtung bewirkt und die Welle an der Verstellhülse gelagert ist.The filling device according to the invention for the suction conveyance of non-homogeneous liquids, such as liquid manure, liquid manure, sewage sludge or faeces, has a housing with an intake port and a discharge port as well as a suction wheel arranged in the housing and held on a drivable shaft, with a cutting knife interacting with a counter cutting edge in the area of the intake manifold is provided, with one end of the shaft extending into the intake manifold and the cutting knife being attached to this end of the shaft in a rotationally fixed manner, and the shaft being axially displaceably mounted in the housing for setting the cutting gap between counter knife and cutting knife. The adjustability of the cutting knife is made possible by an adjusting sleeve arranged coaxially around the shaft, rotation of the adjusting sleeve causing the shaft to move in its axial direction and the shaft being mounted on the adjusting sleeve.
Durch die Verstellbarkeit des Schneidmessers kann die Korngröße der Feststoffe in der nichthomogenen Flüssigkeit angepasst werden, um dadurch Schäden an fasseigenen Kompressoren und Pumpen, beispielsweise einer Schneckenexzenterpumpe, zu vermeiden.Due to the adjustability of the cutting knife, the grain size of the solids in the non-homogeneous liquid can be adjusted in order to avoid damage to barrel-specific compressors and pumps, for example a screw eccentric pump.
Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further embodiments of the invention are the subject of the dependent claims.
Weiterhin können insbesondere zwei beabstandete Lager zur Lagerung der Welle vorgesehen sein. Die Verstellhülse ist vorzugsweise an einer Außenseite des Gehäuses gelagert, wobei dies beispielsweise über eine Gewindeverbindung erfolgen kann. Eine Drehung der Verstellhülse bewirkt dabei eine Verschiebung der Verstellhülse zusammen mit der Welle relativ zum Gehäuse.Furthermore, in particular two spaced bearings can be provided for mounting the shaft. The adjusting sleeve is preferably mounted on an outside of the housing, this being done, for example, by means of a threaded connection can. A rotation of the adjusting sleeve causes a displacement of the adjusting sleeve together with the shaft relative to the housing.
Gemäß einem Ausführungsbeispiel ist das Saugrad von einem konzentrisch um die Welle angeordneten, zylindrischen Gehäuseteil umgeben und der Abführstutzen ist vorzugsweise tangential an diesen zylindrischen Gehäuseteil angeschlossen.According to one embodiment, the suction wheel is surrounded by a cylindrical housing part arranged concentrically around the shaft, and the discharge connection is preferably connected tangentially to this cylindrical housing part.
Weiterhin kann vorgesehen werden, dass ein zusätzlicher Saugrotor mit der Welle rotiert, um die nichthomogene Flüssigkeit vorzubeschleunigen, wobei der Saugrotor insbesondere im Bereich des Ansaugstutzens angeordnet ist.Furthermore, it can be provided that an additional suction rotor rotates with the shaft in order to pre-accelerate the non-homogeneous liquid, the suction rotor being arranged in particular in the area of the intake manifold.
Gemäß einer weiteren Ausgestaltung der Erfindung ist im Bereich des Abführstutzen ein Abstreifer vorgesehen, dessen Abstreifkante parallel zur Welle ausgerichtet ist und der Abstreifer zur Einstellung eines Spaltmaßes zwischen Abstreifkante und Saugrad verstellbar angeordnet ist. Mit dem verstellbaren Abstreifer kann der Spalt so klein wie möglich gehalten werden, um dadurch die Förderleistung der Befüllvorrichtung zu maximieren.According to a further embodiment of the invention, a scraper is provided in the area of the discharge nozzle, the scraper edge of which is aligned parallel to the shaft and the scraper is adjustably arranged to set a gap between the scraper edge and the suction wheel. With the adjustable scraper, the gap can be kept as small as possible in order to maximize the delivery rate of the filling device.
Zum Antrieb der Welle ist an dem dem Schneidmesser gegenüberliegenden Ende der Welle ein Kupplungsbereich vorgesehen, der beispielsweise als Keilwellenbereich ausgebildet ist. Als Antrieb kommt beispielsweise ein Gelenkwellenantrieb oder ein Hydraulikmotor in Betracht.To drive the shaft, a coupling area is provided at the end of the shaft opposite the cutting knife, which is designed, for example, as a spline area. A drive shaft drive or a hydraulic motor can be considered as the drive, for example.
Die Erfindung wird nun anhand der nachfolgenden Beschreibung eines Ausführungsbeispieles und der Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the following description of an embodiment and the drawing.

Die Befüllvorrichtung besteht im Wesentlichen aus einem Gehäuse 1 mit einem Ansaugstutzen 2 und einem Abführstutzen 3 sowie einem im Gehäuse angeordneten und auf eine antreibbaren Welle 4 gehalterten Saugrad 5. Das Saugrad 5 ist dabei von einem konzentrisch um die Welle angeordneten, zylindrischen Gehäuseteil 1a umgeben und der Abführstutzen 3 ist dabei tangential an diesen zylindrischen Gehäuseteil 1a angeschlossen. Der Ansaugstutzen 2 ist koaxial um die Welle 4 angeordnet und weist eine Ansaugöffnung auf. Die nicht näher dargestellte Saugleitung wird an den Ansaugstutzen 2 angeflanscht, während eine nicht näher dargestellte, zum Fasswagen führende Leitung am Abführstutzen 4 angekoppelt wird.The filling device consists essentially of a housing 1 with an
Die Welle wird über eine Verstellhülse 6 gehaltert, wobei die Verstellhülse 6 über eine Gewindeverbindung 7 drehbar an der Außenseite des Gehäuses 1 gelagert ist. Die Welle 4 ist in der Verstellhülse 6 über zwei beabstandete Lager 8, 9 gehaltert, wobei eine Drehung der Verstellhülse 6 eine Verschiebung der Verstellhülse zusammen mit der Welle 4 relativ zum Gehäuse 1 bewirkt.The shaft is held via an adjusting
Die Welle 4 ragt durch das Gehäuse 1 bis in den Ansaugstutzen 2 hinein. An ihrem dortigen Ende ist ein Schneidmesser 10 drehfest angebracht, das mit einer Gegenschneide 11 zusammenwirkt. Ein Verdrehen der Verstellhülse 6 bewirkt somit eine axiale Verschiebung der Welle 4 zusammen mit dem Schneidmesser 10 relativ zur Gegenschneide 11. Auf diese Weise kann ein zwischen Schneidmesser 10 und Gegenschneide 11 entstehender Schneidspalt 12 (siehe
Die Größe des Schneidspaltes 12 legt die Korngröße fest, auf die etwaige Feststoffbestandteile der geförderten Flüssigkeit zerkleinert werden. Die Korngröße ist dabei so einzustellen, dass eine am Fasswagen vorgesehen Pumpe, insbesondere eine Exzenterschneckenpumpe, nicht beschädigt wird. Die Größe des Schneidspaltes 12 hängt dabei insbesondere von der Art der Feststoffe und der zu schützenden Pumpe ab.The size of the cutting
Durch die außerhalb des Gehäuses angebrachte Verstellhülse 6 kann eine Verstellung des Schneidspaltes auch bei angeschlossener Saugleitung werkzeuglos erfolgen.

Gemäß einer weiteren Ausgestaltung der Befüllvorrichtung ist im Bereich des Ansaugstutzens 2 ein mit der Welle 4 mitrotierender Saugrotor 13 vorgesehen, der über eine Buchse 14 auf der Welle 4 gehaltert ist und eine Vorbeschleunigung der zu fördernden, nichthomogenen Flüssigkeit bewirken soll. Sowohl das Saugrad 5 als auch der Saugrotor 13 sind, beispielsweise über Passfedern, drehfest an der Welle 4 gehaltert. Dabei weisen Saugrad und Saugrotor genügend Spiel zu den Wandungen des Gehäuses auf, um die axiale Verschiebung der Welle 4 (zusammen mit Saugrad und Saugrotor) durch Drehen der Verstellhülse 6 zu gewährleisten.According to a further embodiment of the filling device, a
