Abstract
Description
Die Erfindung betrifft eine Rotordüse für ein Hochdruckreinigungsgerät mit einem Gehäuse, in das eine Zufuhrleitung für Reinigungsflüssigkeit einmündet, mit einem Auslaß für die Reinigungsflüssigkeit, mit einem von der Reinigungsflüssigkeit durchströmten, im Gehäuse angeordneten Düsenkörper, der sich mit einem balligen Ende in einem konisch geformten, pfannenförmigen, den Auslaß des Gehäuses umgebenden Lager abstützt und der durch den Strom der Reinigungsflüssigkeit durch das Gehäuse in eine Umlaufbewegung versetzt wird, bei der die Längsachse des Düsenkörpers auf einem Kegelmantel umläuft.The invention relates to a rotor nozzle for a high-pressure cleaning device with a housing into which a supply line for cleaning liquid, with an outlet for the cleaning liquid, with a flowed through by the cleaning liquid, in Nozzle body arranged with a housing crowned end in a conical, pan-shaped, supports the outlet of the housing surrounding the bearing and by the flow of cleaning fluid the housing is rotated at which is the longitudinal axis of the nozzle body on a cone jacket circulates.
Rotordüsen sind beispielsweise aus der DE 40 13 446 B1 bekannt. Durch den Umlauf des Düsenkörpers auf einem Kegelmantel wird auch der von ihm abgegebene und durch den Auslaß aus dem Gehäuse entlassene Strahl des Reinigungsmittels auf einem Kegelmantel geführt, so daß es möglich ist, mit einer solchen Rotordüse eine größere Fläche mit einem Strahl zu überstreichen, der selbst kompakt bleibt und nur einen sehr kleinen Querschnitt hat. Rotor nozzles are for example from DE 40 13 446 B1 known. By rotating the nozzle body on one The cone jacket is also the one it delivers and through the jet of detergent discharged from the housing guided on a cone jacket so that it is possible with such a rotor nozzle a larger To sweep the surface with a beam that itself remains compact and only a very small cross section Has.
Bei derartigen Rotordüsen wird der Düsenkörper mit großer Kraft in axialer Richtung in die Vertiefung hineingedrückt; um diese Kräfte aufnehmen zu können, ist man bei bekannten Rotordüsen daher bestrebt gewesen, spezielle Lagerflächen in das Gehäuse einzusetzen, die der Beanspruchung durch die Anlage des Rotorkörpers gewachsen sind. Dies führt zu einer relativ aufwendigen Konstruktion, da in das Gehäuse ein spezieller Lagerkörper eingesetzt werden muß, der den Düsenkörper abstützt.With such rotor nozzles, the nozzle body becomes larger Force pressed into the recess in the axial direction; to be able to absorb these forces, one is in known rotor nozzles have therefore endeavored to special Insert storage areas in the housing that the Stress grown by the installation of the rotor body are. This leads to a relatively complex construction, because in the housing a special bearing body must be used, which supports the nozzle body.
Aus der DE 90 04 452 U1 ist eine Rotordüse bekannt, bei welcher die Beanspruchung im Lagerbereich dadurch vermieden werden soll, daß komplizierte Abdichtungsmaßnahmen in der Rotordüse vorgenommen werden, beispielsweise durch Verwendung einer Gummimembran. Dies führt zu einer ganz erheblich komplizierteren Konstruktion, bei der trotzdem die Gefahr von Beschädigungen besteht, wenn nämlich die komplizierten Abdichtungsmaßnahmen nicht in vollem Umfange funktionsfähig sind.A rotor nozzle is known from DE 90 04 452 U1, at which avoids the stress in the storage area should be that complicated sealing measures be made in the rotor nozzle, for example by using a rubber membrane. This leads to a very much more complicated construction, at that is still at risk of damage, if only the complicated sealing measures are not fully functional.
In der DE 36 23 368 C1 (vgl. Oberbegriff des Anspruchs 1) ist eine gattungsgemäße Rotordüse beschrieben, bei der ebenfalls ein Düsenkörper mit einem balligen Ende in eine spezielle Lagerschale eintaucht, die in das Gehäuse eingesetzt ist, also auch in diesem Falle ist eine relativ aufwendige Konstruktion notwendig.DE 36 23 368 C1 (cf. preamble of claim 1) is a generic rotor nozzle described in which also a nozzle body with dipped into a special bearing shell at one crowned end, which is inserted in the housing, also in this case is a relatively complex construction necessary.
Es ist Aufgabe der Erfindung, bei einer gattungsgemäßen Rotordüse den Herstellungsaufwand (für eine optimale Abdichtung) zu verringern. It is an object of the invention in a generic Rotor nozzle the manufacturing effort (for an optimal Sealing).
Diese Aufgabe wird bei einer Rotordüse der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß das den Düsenkörper abstützende Lager durch eine in die Innenwand des Gehäuses eingearbeitete, konzentrisch zum Auslaß angeordnete Vertiefung gebildet wird.This task is described in the case of a rotor nozzle Art solved according to the invention in that the the bearing supporting the nozzle body through a in the inner wall of the housing, concentric to the Outlet arranged recess is formed.
Es hat sich überraschenderweise herausgestellt, daß eine in dieser Weise konisch ausgebildete Vertiefung in der Innenwand des Gehäuses in Zusammenwirkung mit der balligen Ausbildung des im Lager abgestützten Endes des Düsenkörpers zu einer optimalen Abdichtung führt, die auch beibehalten wird, wenn Schmutzteilchen und Chemikalien in den Dichtungsbereich gelangen. Die linienförmige Abstützung des ballenförmigen Endes mit der entsprechend verringerten Kontaktfläche führt zu einer wesentlich geringeren Verletzungsmöglichkeit dieser Kontaktflächen, und daher können mit einer solchen Konstruktion auch bei verschmutzter Reinigungsflüssigkeit dann hohe Standzeiten erreicht werden, wenn das Lager unmittelbar Teil des Gehäuses ist, also nicht aus einem speziellen Lagerkörper aus hochverschleißfestem Material besteht. Bei einer solchen Konstruktion ist es also weder notwendig, einen speziellen Lagerkörper aus hochwiderstandsfähigem Material zu verwenden, noch besteht die Notwendigkeit, den Lagerbereich gegenüber der zu fördernden Flüssigkeit in irgendeiner Weise zusätzlich abzudichten.It has surprisingly been found that a recess conically formed in this way the inner wall of the housing in cooperation with the crowned formation of the end of the Nozzle body for an optimal seal leads, which is also maintained when Dirt particles and chemicals in the sealing area reach. The linear support of the ball-shaped In the end with the correspondingly reduced contact area leads to a much lower possibility of injury of these contact areas, and therefore can with such a construction even with dirty cleaning fluid then long service life can be achieved if the bearing is directly part of the housing, not from a special bearing body made of highly wear-resistant Material exists. With one So it is neither necessary to construct a special one Bearing body made of highly resistant material to use, there is still a need to use the storage area compared to the liquid to be pumped in to seal in any way.
Günstig ist es, wenn der Öffnungswinkel der Vertiefung zwischen 110° und 150°, insbesondere zwischen 120° und 140° liegt, vorzugsweise bei 130°.It is beneficial if the opening angle of the depression between 110 ° and 150 °, in particular between 120 ° and 140 °, preferably 130 °.
Das ballige Ende des Düsenkörpers kann kugelig geformt sein, wobei es dann günstig ist, wenn der Radius zwischen 3 mm und 7 mm liegt, vorzugsweise bei 5 mm.The spherical end of the nozzle body can be spherical be, it is then advantageous if the radius between 3 mm and 7 mm, preferably 5 mm.
Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, daß das Gehäuse aus Kunststoff besteht, insbesondere aus Polyamid, wobei es vorteilhaft ist, wenn das Polyamid einen Glasfaseranteil enthält, beispielsweise in der Größenordnung von 30%. In a particularly preferred embodiment provided that the housing is made of plastic, in particular made of polyamide, it being advantageous if the polyamide contains a glass fiber component, for example in the order of 30%.
Gemäß einer bevorzugten Ausführungsform ist vorgesehen, daß das Gehäuse einen Gehäusefuß, in den die Zufuhrleitung einmündet, und eine mit diesem verbindbare Gehäusehaube aufweist, in die der Auslaß mit der Vertiefung eingearbeitet ist. Es ist dadurch möglich, das Gehäuse in einfacher Weise zu trennen, die Gehäusehaube kann ausgetauscht werden, so daß bei Verschleißerscheinungen im Bereich des Lagers einfach eine neue Gehäusehaube auf den Gehäusefuß aufgesetzt wird. Gehäusefuß und Gehäusehaube können vorzugsweise durch Verschraubung miteinander verbindbar sein.According to a preferred embodiment, that the housing has a housing foot into which the supply line opens out, and a housing hood that can be connected to it into which the outlet with the recess is incorporated. This enables the housing can be separated in a simple manner, the housing hood be replaced so that if there are signs of wear just a new housing cover in the area of the warehouse is placed on the housing base. Housing base and housing cover can preferably be screwed together be connectable.
In an sich bekannter Weise kann vorgesehen sein, daß der Düsenkörper aus einem rohrförmigen Körper mit einer in diesen eingesetzten Düse besteht, die das ballige Ende des Düsenkörpers bildet.In a manner known per se it can be provided that the nozzle body from a tubular body with a in this inserted nozzle, which is the crowned End of the nozzle body forms.
Bei einer bevorzugten Ausführungsform ist jedoch vorgesehen, daß der Düsenkörper einen rohrförmigen Körper umfaßt, dessen eines Ende das ballige Ende des Düsenkörpers bildet. In diesem Falle ist also nicht das Einsetzen einer separaten Düse notwendig, sondern der Düsenkörper selbst bildet den Umlaufkörper mit Durchströmungskanal, die Düse und das ballige Ende zur Abstützung in der Vertiefung aus.In a preferred embodiment, however, it is provided that that the nozzle body is a tubular body includes one end of which is the crowned end of the nozzle body forms. In this case, the onset is not a separate nozzle is necessary, but the nozzle body itself forms the circulating body with flow channel, the nozzle and the spherical end for support in the recess.
Auch hier ist es vorteilhaft, wenn der Düsenkörper zumindest im Bereich des balligen Endes aus Kunststoff besteht, insbesondere aus Polyetheretherketon.Again, it is advantageous if the nozzle body at least in the area of the spherical end made of plastic consists, in particular of polyether ether ketone.
Die Materialpaarung glasfaserverstärktes Polyamid/Polyetheretherketon ist dabei besonders verschleißarm, so daß mit einer Paarung derartiger Kunststoffe hohe Standzeiten erreicht werden, obwohl keine speziellen Lagerkörper vorgesehen sind. Insgesamt lassen sich dadurch die Herstellungskosten und der Herstellungsaufwand erheblich reduzieren, denn es genügt, Düsenkörper und Gehäusehauben aus Kunststoff in der üblichen Herstellungsweise herzustellen, diese Teile können dann ohne weitere Veränderungen in der Rotordüse eingesetzt werden.The material pairing glass fiber reinforced polyamide / polyether ether ketone is particularly low-wear, so that high with a pairing of such plastics Downtimes can be achieved, although no special ones Bearing body are provided. Overall, this allows the manufacturing costs and the manufacturing costs reduce significantly, because it is enough nozzle body and plastic hoods in the usual way of production can then manufacture these parts used without further changes in the rotor nozzle become.

geringen Verschleiß, so daß mit einer solchen
Rotordüse hohe Standzeiten zu erreichen sind. Die Teile
sind jedoch in einfachster Weise herzustellen, da die
Haube 7 als einstückiges Formteil ausgebildet ist, und
dasselbe gilt im wesentlichen auch für den Düsenkörper
11. Diese Teile können auch in einfachster Weise ausgetauscht
werden, indem die Haube 7 vom Gehäusefuß 2 abgeschraubt
und durch eine neue ersetzt wird. Bei dieser
Gelegenheit kann auch der Düsenkörper 11 in einfacher
Weise ausgetauscht werden, falls der Verschleiß ein bestimmtes
