Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft eine Vorrichtung zur Innenreinigung von Behältern, z.B. Tanks, nach dem Oberbegriff des unabhängigen Anspruchs 1 oder 3.The invention relates to a device for cleaning the inside of containers, e.g. Tanks, according to the preamble of independent claim 1 or 3.

STAND DER TECHNIKSTATE OF THE ART

Eine Vorrichtung zur Innenreinigung von Behältern, z.B. Tanks, ist beispielsweise hinsichtlich ihres grundsätzlichen Aufbaus aus der DE 26 45 401 A1 bekannt. Eine derartige Vorrichtung wird in Fachkreisen auch als so genannter Zielstrahlreiniger bezeichnet. Sie basiert, ähnlich wie die Behälterreinigung mittels einer Sprühkugel, auf dem Niederdruck-Reinigungsprinzip. Im Gegensatz zur Sprühkugelreinigung, bei der mehr oder weniger die gesamte innere Oberfläche des Tanks gleichzeitig über eine Vielzahl von an der Sprühkugel angebrachten Bohrungen mit Reinigungsflüssigkeit beaufschlagt wird, beschwallt bei einem Zielstrahlreiniger ein langsam umlaufender Fächerstrahl nur jeweils Teilbereiche der Behälterwand. Es hat sich gezeigt, dass ein derartiger Fächerstrahl auf der Behälterwand eine Intervallspülung mit pulsierendem Schwall bewirkt, wobei im Vergleich zur Sprühkugel trotz stark reduziertem Reinigungsflüssigkeits-Durchsatz eine mindestens wirkungsgleiche Reinigung gegeben ist.A device for cleaning the inside of containers, for example tanks, is known, for example, with regard to its basic structure from DE 26 45 401 A1 . Such a device is also known in specialist circles as a so-called aiming jet cleaner. Similar to container cleaning using a spray ball, it is based on the low-pressure cleaning principle. In contrast to spray ball cleaning, in which more or less the entire inner surface of the tank is simultaneously supplied with cleaning liquid through a large number of holes in the spray ball, a slow-moving fan jet only drows up partial areas of the container wall in a target jet cleaner. It has been shown that such a fan jet on the container wall causes an interval rinse with pulsating gush, whereby in comparison to the spray ball, despite the greatly reduced cleaning fluid throughput, cleaning is at least effective.

Der Antrieb der seit langem bekannten Zielstrahlreiniger erfolgt über ein selbstreinigendes Strömungsgetriebe, das seine Antriebsenergie aus der Strömungsenergie der dem Reiniger zugeführten Reinigungsflüssigkeit bezieht. Bei dem Strömungsgetriebe handelt es sich um eine Turbine, die im Reinigungsflüssigkeits-Zulauf außerhalb des Tanks angeordnet ist. In der Regel wird die Drehzahl der Turbinenwelle über ein Schneckengetriebe und anschließend ein Winkelgetriebe auf ein in den Tankinnenraum bis zu einem Düsenhalter hinein geführtes Antriebsgestänge übertragen. Ein derartiger Zielstrahlreinigerantrieb ist einerseits sehr wartungsfreundlich, da alle ausbaufähigen Teile außerhalb des zu reinigenden Tanks installiert sind (vergleiche hierzu beispielsweise die Firmendruckschrift 4.003.0 "Reinigungsgeräte" der Firma Tuchenhagen, Büchen, Seite 3), andererseits ist allerdings eine derartige Antriebsausgestaltung wegen der notwendigen großen Übersetzungsverhältnisse und der erforderlichen Richtungsänderung des Kraftflusses zwischen der Richtung der Turbinenwelle und der Richtung der Drehachse des Düsenhalters sowohl räumlich als auch kostenmäßig relativ aufwändig.The long-known jet cleaner is driven by a self-cleaning flow gear, which draws its drive energy from the flow energy of the cleaning fluid supplied to the cleaner. The flow gear is a turbine which is arranged outside the tank in the cleaning liquid inlet. As a rule, the speed of the turbine shaft is transmitted via a worm gear and then an angular gear to a drive linkage which is guided into the tank interior up to a nozzle holder. Such a jet cleaner drive is, on the one hand, very easy to maintain, since all expandable parts are installed outside the tank to be cleaned (see, for example, company document 4.003.0 "Cleaning Devices" from Tuchenhagen, Büchen, page 3), but on the other hand, such a drive design is necessary Large gear ratios and the required change in direction of the power flow between the direction of the turbine shaft and the direction of the axis of rotation of the nozzle holder, both in terms of space and cost, are relatively complex.

Aus der DE 198 11 421 A1 ist eine Tankreinigungsvorrichtung bekannt, die in einem drehfesten Gehäuseteil ihres Gehäuse eine durch die Strömungsenergie der zugeführten Reinigungsflüssigkeit angetriebene Turbine aufweist. Die Drehbewegung der Turbine wird über ein Planetengetriebe auf einen gegenüber dem drehfesten Gehäuseteil um eine erste Drehachse drehbaren Düsenhalter übertragen. Letzterer treibt über ein Kegelradgetriebe eine Düsenanordnung an, die am Düsenhalter um eine zweite Drehachse drehbar gelagert ist. Dabei sind jeweils zwei Düsen der mit insgesamt vier Düsen ausgestatteten Düsenanordnung im spitzen Winkel zueinander als V-Formation angeordnet, wobei die beiden V-Formationen im Wesentlichen in entgegen gesetzte Richtungen weisen. Durch diese Düsenanordnung ist die Einführung der Tankreinigungsvorrichtung in schmale Tanköffnungen möglich.From DE 198 11 421 A1 a tank cleaning device is known which has a turbine driven by the flow energy of the supplied cleaning liquid in a non-rotatable housing part of its housing. The rotational movement of the turbine is transmitted via a planetary gear to a nozzle holder which is rotatable about a first axis of rotation with respect to the rotationally fixed housing part. The latter drives a nozzle arrangement via a bevel gear, which is rotatably mounted on the nozzle holder about a second axis of rotation. In this case, two nozzles of the nozzle arrangement equipped with a total of four nozzles are arranged at an acute angle to one another as a V formation, the two V formations essentially pointing in opposite directions. This nozzle arrangement enables the tank cleaning device to be inserted into narrow tank openings.

Eine weitere Tankreinigungsvorrichtung ist in der US 53 33 630 A beschrieben, bei der ein mit Düsen ausgestatteter Düsenhalter einander überlagerte Drehbewegungen um eine erste und eine zweite Drehachse ausführt. Der Antrieb des Düsenhalters erfolgt über eine durch die Strömungsenergie der zugeführten Reinigungsflüssigkeit angetriebene Turbine, wobei die Kinematik des Getriebes zwischen Turbine und Düsenhalter im Wesentlichen jener gemäß DE 198 11 421 A1 entspricht. Die aus der US 53 33 630 A bekannte Tankreinigungsvorrichtung ist nicht nur selbstreinigend hinsichtlich ihrer von der Reinigungsflüssigkeit durchströmten inneren Bereiche ausgeführt, sondern sämtliche Durchtrittsspalte zwischen relativ zueinander bewegten Bauteilen werden zum Zwecke ihrer Reinigung jeweils mit einer begrenzten Menge Reinigungsflüssigkeit durchströmt, die nach Austritt in die Umgebung derart geführt werden, dass eine Reinigung auch der äußeren Oberflächen der Tankreinigungsvorrichtung erfolgt. Another tank cleaning device is described in US Pat. No. 5,333,630 A , in which a nozzle holder equipped with nozzles executes rotary movements superimposed on one another about a first and a second axis of rotation. The nozzle holder is driven by a turbine driven by the flow energy of the cleaning liquid supplied, the kinematics of the transmission between the turbine and nozzle holder essentially corresponding to that according to DE 198 11 421 A1. The tank cleaning device known from US 53 33 630 A is not only designed to be self-cleaning with regard to its inner areas through which the cleaning liquid flows, but all the passage gaps between components which are moved relative to one another are flowed through for the purpose of their cleaning in each case with a limited amount of cleaning liquid which flows into the Be guided in such a way that the outer surfaces of the tank cleaning device are also cleaned.

Eine Vorrichtung zur Innenreinigung von Behältern, z.B. Tanks, der gattungsgemäßen Art, bei der die Drehbewegung der Turbinenwelle mittelbar auf einen Lagerarm übertragen wird, der mittels einer im Gehäuse und koaxial zur Drehachse des Düsenhalters gelagerten Traverse um die Drehachse drehbar und geführt angeordnet ist, ist aus der GB 11 96 511 A bekannt. Der Düsenhalter, dessen Drehachse koaxial zur Längsachse des stationären Gehäuses und auch der Turbinenwelle verläuft, dient dort zusätzlich der außenseitigen Lagerung eines um eine zweite Drehachse drehbaren Düsengehäuses, wobei diese zweite Drehachse gegenüber der Drehachse des Düsenhalters einen Winkel von 90 Grad bildet. Insoweit weist auch diese Tankreinigungsvorrichtung die in der US 53 33 630 A beschriebene Bewegungskinematik eines Tankreinigers auf, die sich dadurch auszeichnet, dass ein mit wenigstens einer Düse ausgestattetes Düsengehäuse einander überlagerte Drehbewegungen um eine erste und eine zweite Drehachse ausführt. Nicht immer ist die Drehung um die zweite Drehachse mit Blick auf die angestrebte Reinigungswirkung (Intervallspülung mit pulsierendem Schwall, wie vorstehend erwähnt) auch hilfreich oder erforderlich. Im Unterschied zur US 53 33 630 A sind bei der Vorrichtung gemäß GB 11 96 511 A die Getriebeteile in einem separaten Gehäuse angeordnet, das von der die Vorrichtung beaufschlagenden und antreibenden Reinigungsflüssigkeit nicht durchströmt wird, sodass das Getriebe nicht selbstreinigend ist. A device for cleaning the inside of containers, e.g. tanks, of the generic type, in which the rotary movement of the turbine shaft is transmitted indirectly to a bearing arm which is arranged so as to be rotatable and guided about the axis of rotation by means of a cross member mounted in the housing and coaxially with the axis of rotation of the nozzle holder known from GB 11 96 511 A. The nozzle holder, the axis of rotation of which runs coaxially to the longitudinal axis of the stationary housing and also of the turbine shaft, is also used there for the external mounting of a nozzle housing which can be rotated about a second axis of rotation, this second axis of rotation forming an angle of 90 degrees with respect to the axis of rotation of the nozzle holder. In this respect, this tank cleaning device also has the movement kinematics of a tank cleaner described in US Pat. No. 5,333,630 A , which is characterized in that a nozzle housing equipped with at least one nozzle executes superimposed rotary movements about a first and a second axis of rotation. The rotation around the second axis of rotation is not always helpful or necessary in view of the desired cleaning effect (interval flushing with pulsating gush, as mentioned above). In contrast to US 53 33 630 A, in the device according to GB 11 96 511 A, the gear parts are arranged in a separate housing, through which the cleaning fluid acting and driving the device does not flow, so that the gear is not self-cleaning.

Die Tankreinigungsvorrichtungen gemäß DE 198 11 421 A1, US 53 33 630 A und GB 11 96 511 A sind gegenüber dem sog. Zielstrahlreiniger gemäß DE 26 45 401 A1 einerseits deutlich kompakter, andererseits jedoch konstruktiv wesentlich komplizierter aufgebaut.The tank cleaning devices according to DE 198 11 421 A1, US 53 33 630 A and GB 11 96 511 A are compared to the so-called DE 26 45 401 A1 on the one hand significantly more compact, but on the other hand constructive much more complicated.

Es ist Aufgabe der vorliegenden Erfindung, eine Vorrichtung zur Innenreinigung von Behältern, z.B. Tanks, der gattungsgemäßen Art zu schaffen, die langsam laufend und gleichzeitig sehr kompakt und konstruktiv relativ einfach ausgeführt ist.It is an object of the present invention to provide an internal cleaning device of containers, e.g. Tanks, of the generic type, that create slowly ongoing and at the same time very compact and structurally relatively simple is.

ZUSAMMENFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION

Die Aufgabe wird durch eine Vorrichtung mit den Merkmalen des unabhängigen Anspruchs 1 oder 3 gelöst. Vorteilhafte Ausführungsformen der efindungsgemäßen Vorrichtung sind Gegenstand von Unteransprüchen.The task is accomplished by a device with the features of the independent Claim 1 or 3 solved. Advantageous embodiments of the invention Device are the subject of dependent claims.

Der als Hohlkörper ausgebildete Düsenhalter nimmt nicht nur wenigstens eine Düse zur Erzeugung eines Spritzstrahles oder mehrerer Spritzstrahlen und den hierzu notwendigen Raum zur Zuleitung der Reinigungsflüssigkeit auf, sondern auch einen Teil des Gehäuses der Vorrichtung, in dem die Turbinenwelle und alle Getriebeteile zur Transformation der Drehzahl der Turbinenwelle auf die extrem niedrige Drehzahl des Düsenhalters (wenige Umdrehungen je Minute) angeordnet sind. Eine weitere, entscheidende Maßnahme besteht darin, dass die Turbine im rohrförmigen Gehäuseteil des Gehäuses in unmittelbarer Nähe zu dessen Durchdringungsstelle mit dem Düsenhalter angeordnet ist. Dadurch wird es möglich, Turbine und Getriebe in unmittelbarer Nähe zueinander anzuordnen, so dass auf mehr oder weniger lange Übertragungsgestänge zwischen diesen beiden Komponenten, die ggf. von Fall zu Fall noch auf die örtlichen Gegebenheiten anzupassen sind, verzichtet werden kann.The nozzle holder designed as a hollow body does not only take at least one Nozzle for generating one or more spray jets and the necessary space for supplying the cleaning liquid, but instead also part of the housing of the device in which the turbine shaft and all Gear parts to transform the speed of the turbine shaft to the extreme low speed of the nozzle holder (a few revolutions per minute) arranged are. Another decisive measure is that the turbine in the tubular housing part of the housing in the immediate vicinity of its penetration point is arranged with the nozzle holder. This makes it possible Place the turbine and gearbox in close proximity to each other, so that on more or less long transmission linkage between these two components, which may need to be adapted to the local conditions from case to case are dispensed with.

Eine erste Ausführungsform der vorgeschlagenen Vorrichtung sieht vor, die Drehbewegung der Turbinenwelle unmittelbar auf den Lagerarm zu übertragen, der gemäß einer vorteilhaften Ausgestaltung derart in einer Traverse gelagert ist, dass er eine um die Drehachse des Düsenhalters geführte Bewegung ausführt. Auf diesem Lagerarm ist ein so genanntes Planetenrad drehbeweglich angeordnet, das einerseits mit einem ersten innen verzahnten Außenrad am Düsenhalter und andererseits mit einem zweiten innen verzahnten Außenrad am Gehäuse im Eingriff ist. Eine diesbezügliche getriebetechnische Anordnung erlaubt es, durch Wahl der jeweiligen Zähnezahl dieser Außenräder ein großes Übersetzungsverhältnis zu realisieren, das ansonsten nur mit mehrstufigen Getrieben und/oder durch Einbeziehung eines Schneckengetriebes erreichbar ist. Unterscheiden sich beispielsweise die Zähnezahlen der beiden mit dem Planetenrad gleichermaßen kämmenden Außenräder um wenigstens einen Zahn, dann ist bei Zähnezahlen von beispielsweise 90 und 91 ein Übersetzungsverhältnis von i2 = 90/1 möglich.A first embodiment of the proposed device provides for the rotary movement of the turbine shaft to be transmitted directly to the bearing arm which, according to an advantageous embodiment, is mounted in a crossmember in such a way that it executes a movement guided about the axis of rotation of the nozzle holder. A so-called planet gear is rotatably arranged on this bearing arm and engages on the one hand with a first internally toothed outer wheel on the nozzle holder and on the other hand with a second internally toothed outer wheel on the housing. A gearbox arrangement in this regard allows a large transmission ratio to be achieved by selecting the number of teeth of these outer wheels, which can otherwise only be achieved with multi-stage gearboxes and / or by incorporating a worm gearbox. If, for example, the number of teeth of the two outer wheels equally meshing with the planet gear differs by at least one tooth, then a gear ratio of i 2 = 90/1 is possible with number of teeth of 90 and 91, for example.

Eine zweite Ausführungsform der vorgeschlagenen Vorrichtung ermöglicht ein noch größeres Übersetzungsverhältnis zwischen antreibender Turbine und getriebenem Düsenhalter, und zwar dadurch, dass zwischen Turbinenwelle und dem Lagerarm, der mittels einer im Gehäuse und koaxial zur Drehachse gelagerten Traverse um die Drehachse drehbar und geführt angeordnet ist, ein Zwischengetriebe vorgesehen ist. Dieses Zwischengetriebe kann in vielfältiger Weise ausgestaltet sein. Es hat sich als zweckmäßig erwiesen, wenn es als Stirnradgetriebe ausgeführt ist, bei dem die Turbinenwelle an ihrem dem Laufrad abgewandten Ende ein Ritzel trägt, das mit einem mit dem Lagerarm fest verbundenen dritten innen verzahnten Außenrad im Eingriff steht. Abhängig vom Übersetzungsverhältnis i1 dieses Zwischengetriebes lässt sich das Gesamtübersetzungsverhältnis iges des Antriebes für die erfindungsgemäße Vorrichtung entsprechend erhöhen.A second embodiment of the proposed device enables an even greater transmission ratio between the driving turbine and the driven nozzle holder, specifically in that between the turbine shaft and the bearing arm, which is arranged so as to be rotatable and guided about the axis of rotation by means of a cross member mounted in the housing and coaxially with the axis of rotation Intermediate gear is provided. This intermediate gear can be designed in a variety of ways. It has proven to be expedient if it is designed as a spur gear, in which the turbine shaft carries a pinion at its end facing away from the impeller, which pinion engages with a third internally toothed outer wheel which is fixedly connected to the bearing arm. Depending on the gear ratio i 1 of this intermediate gear, the overall gear ratio i ges of the drive for the device according to the invention can be increased accordingly.

Der im Rahmen der vorliegenden Erfindung vorgeschlagene Antrieb baut in überraschender Weise kompakt und Raum sparend, so dass der Düsenhalter in an sich bekannter Weise als Hohlkugel ausgeführt werden kann. In dieser Hohlkugel sind das Getriebe, die Verbindungsmittel zwischen letzterem und der Turbine und ausreichend bemessene Strömungsquerschnitte zu wenigstens einer am Düsenhalter angeordneten Düse angeordnet. Darüber hinaus wird der Düsenhalter vom rohrförmigen Gehäuseteil des Gehäuse zentrisch durchdrungen. The drive proposed in the context of the present invention builds in a surprising manner Way compact and space-saving, so that the nozzle holder in on can be carried out in a known manner as a hollow sphere. In this hollow sphere are the transmission, the connecting means between the latter and the turbine and Sufficiently dimensioned flow cross sections to at least one on the nozzle holder arranged nozzle arranged. In addition, the nozzle holder from tubular housing part of the housing penetrated centrally.

Der als Hohlkugel ausgebildete Düsenhalter stellt einerseits eine nahezu ideale geometrische Form für ein Reinigungsgerät in einem zu reinigenden Tank dar, andererseits schafft die Kugel als geometrisches Gebilde ideale räumliche Vorraussetzungen für die im Rahmen der vorgeschlagenen Vorrichtung notwendigen Bauteile innerhalb dieses kugelförmigen Gebildes. Die Zugänglichkeit zu den Antriebsteilen innerhalb der Vorrichtung wird dadurch auf sehr einfache und wirksame Weise sichergestellt, dass der Düsenhalter in einer auf der Längsachse des rohrförmigen Gehäuseteils senkrecht stehenden Meridianebene geteilt ausgeführt ist. Diese Teilung ist in der Regel form- und kraftschlüssig ausgeführt, wobei beispielsweise Verschraubungs- oder so genannte Sprengringelemente zur Anwendung kommen.The nozzle holder, which is designed as a hollow ball, is an almost ideal one represents a geometric shape for a cleaning device in a tank to be cleaned, on the other hand, as a geometric structure, the sphere creates ideal spatial conditions for the necessary in the context of the proposed device Components within this spherical structure. Accessibility to the drive parts within the device this is very simple and effective Way ensured that the nozzle holder in a on the longitudinal axis of the tubular housing part vertically standing meridian plane divided is. This division is usually carried out in a positive and non-positive manner, for example Screwing or so-called snap ring elements for use come.

Wird, wie dies ein weiterer Vorschlag vorsieht, die Anordnung derart getroffen, dass die Drehachse des Düsenhalters mit der Längsachse des rohrförmigen Gehäuseteils zusammenfällt, dann ergibt sich eine besonders einfache, symmetrische Anordnung, in der das Laufrad der Turbine den Durchtrittsquerschnitt des rohrförmigen Gehäuseteils vollständig ausfüllt. Somit liegt die Turbine im ungeschmälerten Zuleitungsweg für die Reinigungsflüssigkeit, da in der Regel der rohrförmige Gehäuseteil und die Zuleitung für Reinigungsflüssigkeit querschnittsgleich und geometrisch kongruent ausgeführt sind.If, as a further proposal provides, the arrangement is made in such a way that the axis of rotation of the nozzle holder with the longitudinal axis of the tubular housing part coincides, then there is a particularly simple, symmetrical Arrangement in which the impeller of the turbine has the passage cross section of the completely fills the tubular housing part. The turbine is thus undiminished Supply path for the cleaning liquid, as a rule tubular housing part and the feed line for cleaning liquid with the same cross-section and are geometrically congruent.

Weist, wie dies ein weiterer Vorschlag vorsieht, das erste innen verzahnte Außenrad eine Zähnezahl z1 = 91 und das zweite innen verzahnte Außenrad eine Zähnezahl z2 = 90 auf, so dass ein Übersetzungsverhältnis von i2 = 90/1 gegeben ist, und wird, gemäß einem weiteren Vorschlag, das Übersetzungsverhältnis des Zwischengetriebes mit i1 = 4/1 bemessen, dann ergibt sich ein Gesamtübersetzungsverhältnis des Antriebes von iges = 90/1 x 4/1 = 360/1. Dies bedeutet in der Praxis, da die antreibende Turbine, abhängig vom Reinigungsflüssigkeits-Durchsatz, in einem Drehzahlbereich von etwa 300 bis 800 min-1 arbeitet, dass je nach Ausgestaltung des Planeten- und des Zwischengetriebes eine Drehzahl bis herunter auf 1 bis 2 min-1 möglich ist, so dass die gestellte Aufgabe, eine äußerst langsam laufende Vorrichtung zur Innenreinigung von Behältern zu schaffen, die gleichzeitig kompakt ausgeführt ist, in sehr eindrucksvoller Weise gelöst ist.As another proposal provides, the first internally toothed outer wheel has a number of teeth z 1 = 91 and the second internally toothed outer wheel has a number of teeth z 2 = 90, so that a transmission ratio of i 2 = 90/1 is given , measured according to a further proposal, the transmission ratio of the intermediate gear with i 1 = 4/1, then a total gear ratio of the drive of i ges = 90/1 yields x 4/1 = 360/1. In practice, this means that the driving turbine, depending on the cleaning fluid throughput, operates in a speed range of around 300 to 800 min -1 , depending on the design of the planetary gear and the intermediate gear, a speed down to 1 to 2 min - 1 is possible, so that the task of creating an extremely slow-running device for cleaning the inside of containers, which at the same time is compact, is solved in a very impressive manner.

DETAILLIERTE BESCHREIBUNGDETAILED DESCRIPTION

Ein als Hohlkugel ausgeführter, drehbar gelagerter Düsenhalter 1 (Figur 1) trägt an seiner Kugeloberfläche eine erste Düse 1a und diametral hierzu eine zweite Düse 1b. Er wird von einem rohrförmigen Gehäuseteil 2a, das Teil eines stationären Gehäuses 2 ist, zentrisch durchdrungen. Der im Innenraum des Düsenhalters 1 angeordnete Teil des Gehäuses 2 teilt sich auf in einen äußeren Lagerträger 2b und einen über nicht näher bezeichnete Arme befestigten inneren Lagerträger 2c. Der äußere Lagerträger 2b dient in seinem oberen Bereich der Aufnahme eines ersten Düsenhalterlagers 6a und in seinem unteren Bereich eines zweiten Düsenhalterlagers 6b. Über diese beiden Lagerstellen 6a, 6b wird der Düsenhalter 1 drehbeweglich auf dem Gehäuse 2 gelagert und geführt, wobei das erste Düsenhalterlager 6a dem oberen Bereich des Düsenhalters 1 im Bereich seiner Durchdringungsstelle mit dem rohrförmigen Gehäuseteil 2a und das zweite Düsenhalterlager 6b dem unteren Bereich des Düsenhalters 1 in Gestalt eines Lagerteils 1c zugeordnet sind.A rotatably mounted nozzle holder 1 ( FIG. 1 ) designed as a hollow ball carries a first nozzle 1a on its ball surface and diametrically to this a second nozzle 1b. It is penetrated centrally by a tubular housing part 2a, which is part of a stationary housing 2. The part of the housing 2 which is arranged in the interior of the nozzle holder 1 is divided into an outer bearing bracket 2b and an inner bearing bracket 2c fastened by means of arms (not designated in more detail). The outer bearing support 2b serves to receive a first nozzle holder bearing 6a in its upper region and a second nozzle holder bearing 6b in its lower region. About these two bearing points 6a, 6b, the nozzle holder 1 is rotatably mounted and guided on the housing 2, the first nozzle holder bearing 6a the upper region of the nozzle holder 1 in the region of its penetration point with the tubular housing part 2a and the second nozzle holder bearing 6b the lower region of the nozzle holder 1 in the form of a bearing part 1c.

Gemäß einer vorteilhaften Ausführungsform ist der Düsenhalter 1 in einer auf einer Längsachse L des rohrförmigen Gehäuseteils 2a senkrecht stehenden Meridianebene geteilt, so dass oberhalb ein erster Düsenhalterteil 1.1 und unterhalb ein zweiter Düsenhalterteil 1.2 entstehen. Die Verbindung beider Düsenhalterteile 1.1 und 1.2 erfolgt zweckmäßigerweise form- und kraftschlüssig, beispielsweise über Verschraubungselemente oder eine so genannte Sprengringverbindung, die im Ausführungsbeispiel nicht dargestellt und bezeichnet sind.According to an advantageous embodiment, the nozzle holder 1 is in one on one Longitudinal axis L of the tubular housing part 2a vertical meridian plane divided, so that a first nozzle holder part 1.1 and below a second nozzle holder part 1.2 arise. The connection of both nozzle holder parts 1.1 and 1.2 are expediently positive and non-positive, for example via screw elements or a so-called snap ring connection, the are not shown and designated in the exemplary embodiment.

Eine Turbine 3 ist mit einem Laufrad 3a, einer Nabe 3b und einer in letzterer angeordneten Turbinenwelle 3c im rohrförmigen Gehäuseteil 2a in unmittelbarer Nähe zu dessen Durchdringungsstelle mit dem Düsenhalter 1 angeordnet. Die Turbinenwelle 3c ist in den Düsenhalter 1 hineingeführt und dort im inneren Lagerträger 2c zweifach gelagert. Der Lagerung im oberen Bereich dient hierzu ein erstes Turbinenlager 7a und im unteren Bereich ein zweites Turbinenlager 7b. Das der Turbine 3 abgewandte Ende der Turbinenwelle 3c ist fest mit einem Lagerarm 3d verbunden, der mittels einer außenseits auf dem inneren Lagerträger 2c und koaxial zu einer Drehachse D des Düsenhalters 1 gelagerten Traverse 4 um die Drehachse D drehbar und geführt angeordnet ist. Der Lagerarm 3d trägt in drehbeweglicher Anordnung ein Planetenrad 5, das einerseits mit einem ersten innen verzahnten Außenrad 1d, welches in fester Verbindung mit dem zweiten Düsenhalterteil 1.2 des Düsenhalters 1 steht, und andererseits mit einem zweiten innen verzahnten Außenrad 2d, das fest mit dem äußeren Lagerträger 2b des Gehäuses 2 verbunden ist, im Eingriff ist. Zum Zwecke des Massenausgleichs befindet sich auf der dem Lagerarm 3d gegenüber liegenden Seite ein mit der Turbinenwelle 3c verbundenes Gegengewicht 3e.A turbine 3 is arranged with an impeller 3a, a hub 3b and one in the latter Turbine shaft 3c in the tubular housing part 2a in the immediate vicinity Arranged in proximity to its penetration point with the nozzle holder 1. The Turbine shaft 3c is guided into the nozzle holder 1 and there in the inner bearing bracket 2c stored twice. The storage in the upper area is used for this first turbine bearing 7a and in the lower area a second turbine bearing 7b. The end of the turbine shaft 3c facing away from the turbine 3 is fixed with a bearing arm 3d connected by means of an outside on the inner bearing bracket 2c and coaxial to an axis of rotation D of the nozzle holder 1 is arranged to be rotatable and guided about the axis of rotation D. The bearing arm 3d carries in rotatable arrangement of a planet gear 5, the one hand with a first internally toothed outer wheel 1d, which is in fixed connection with the second Nozzle holder part 1.2 of the nozzle holder 1 stands, and on the other hand with a second internally toothed outer wheel 2d, which is fixed to the outer bearing bracket 2b of the Housing 2 is connected, is engaged. For the purpose of mass balancing is on the side opposite the bearing arm 3d with the Turbine shaft 3c connected counterweight 3e.

Das durch die Energie des zuströmenden Reinigungsmittels angetriebene Laufrad 3a der Turbine 3 überträgt seine Drehbewegung auf die Turbinenwelle 3c und somit synchron auf den Lagerarm 3d, der in fester Verbindung und in radialem Abstand zur Turbinenwelle 3c angeordnet ist. Die umlaufende Drehbewegung des Lagerarms 3d wird zusätzlich durch die konzentrisch zur Turbinenwelle 3c gelagerte Traverse 4 geführt. Im Bereich des Lagerarmes 3d ist die Traverse 4 vorzugsweise gabelförmig ausgebildet, so dass das Planetenrad 5, das drehbeweglich auf dem Lagerarm 3d angeordnet ist, in axialer Richtung beidseitig eine Begrenzung erfährt. Die Zähnezahlen der innen verzahnten Außenräder 1d und 2d unterscheiden sich zweckmäßig um einen Zahn, und die Verzahnung ist in Bezug auf das Planetenrad 5 derart ausgebildet, dass letzteres gleichermaßen auf dem gleichen Teilkreisdurchmesser mit dem ersten und dem zweiten innen verzahnten Außenrand 1d bzw. 2d im Eingriff ist. Dadurch ergibt sich nach einem vollständigen Umlauf des Lagerarmes 3d in Verbindung mit dem auf ihm gelagerten Planetenrad 5 eine Umfangsverschiebung zwischen den beiden innen verzahnten Außenrädern 1d und 2d nach Maßgabe der einem Zahn entsprechenden Teilung.The impeller driven by the energy of the incoming cleaning agent 3a of the turbine 3 transmits its rotational movement to the turbine shaft 3c and thus synchronized with the bearing arm 3d, which is in a fixed connection and in a radial Distance to the turbine shaft 3c is arranged. The rotating movement of the Bearing arm 3d is additionally supported by the one that is concentric with the turbine shaft 3c Traverse 4 led. In the area of the bearing arm 3d, the cross member 4 is preferred fork-shaped, so that the planet gear 5, the rotatable is arranged on the bearing arm 3d, a limitation in the axial direction on both sides experiences. The number of teeth of the internally toothed outer wheels 1d and 2d differ appropriately by a tooth, and the toothing is related formed on the planet gear 5 such that the latter equally on the same pitch circle diameter with the first and the second internally toothed Outer edge 1d or 2d is engaged. This results in a complete Circulation of the bearing arm 3d in connection with the planet gear mounted on it 5 a circumferential shift between the two internally toothed outer wheels 1d and 2d according to the pitch corresponding to a tooth.

Wird beispielsweise, wie dies vorgesehen ist, die Zähnezahl des ersten innen verzahnten Außenrades 1d mit z1 = 91 und jene des zweiten innen verzahnten Außenrades 2d mit z2 = 90 Zähne gewählt, dann ergibt sich nach 90 Umläufen des Lagerarmes 3d insgesamt eine Relativverschiebung zwischen dem ersten und dem zweiten innen verzahnten Außenrad 1d bzw. 2d um eine volle Umdrehung. Ein derart ausgestaltetes Planetengetriebe besitzt somit ein Übersetzungsverhältnis von i2 = 90/1, so dass beispielsweise 90 Umdrehungen der Turbine 3 eine Umdrehung des Düsenhalters 1 ergeben. If, for example, as is provided, the number of teeth of the first internally toothed outer wheel 1d with z 1 = 91 and that of the second internally toothed outer wheel 2d with z 2 = 90 teeth is selected, then after 90 rotations of the bearing arm 3d there is a total relative displacement between the first and second internally toothed outer wheels 1d and 2d by one full turn. A planetary gear designed in this way thus has a transmission ratio of i 2 = 90/1, so that, for example, 90 revolutions of the turbine 3 result in one revolution of the nozzle holder 1.

Nach einer zweiten Ausführungsform (Figur 2) wird die Drehbewegung der Turbinewelle 3c mittelbar auf den Lagerarm 3d übertragen. Dies geschieht durch Zwischenschaltung eines Zwischengetriebes, welches im dargestellten Ausführungsbeispiel als Stirnradgetriebe mit einem Ritzel 8 und einem innen verzahnten Außenrad 9 ausgebildet ist. Das Ritzel 8 ist auf dem dem Laufrad 3a abgewandten Ende der Turbinenwelle 3c angeordnet und es steht im ständigen Eingriff mit der Innenverzahnung des Außenrades 9, welches fest mit dem Lagerarm 3d verbunden ist.According to a second embodiment ( FIG. 2 ), the rotary movement of the turbine shaft 3c is transmitted indirectly to the bearing arm 3d. This is done by interposing an intermediate gear, which in the exemplary embodiment shown is designed as a spur gear with a pinion 8 and an internally toothed outer wheel 9. The pinion 8 is arranged on the end of the turbine shaft 3c facing away from the impeller 3a and is in constant engagement with the internal toothing of the outer wheel 9, which is firmly connected to the bearing arm 3d.

Wird beispielsweise, wie dies vorgeschlagen wird, das Übersetzungsverhältnis des Zwischengetriebes mit i1 > 1 ausgeführt, vorzugsweise i1 ≥ 4:1, dann ergibt sich für den Antrieb ein Gesamtübersetzungsverhältnis iges = i1 x i2, d.h. im vorliegenden Fall iges = 4/1 x 90/1 = 360/1. Ein Übersetzungsverhältnis i1 = 4/1 ist beispielsweise mit einer Zähnezahl z4 = 15 für das Ritzel 8 und einer Zähnezahl z5 = 60 für das innen verzahnte Außenrad 9 erreichbar. Das Planetenrad 5 innerhalb des Planetengetriebes 5, 1d, 2d wird in beiden Ausführungsformen beispielsweise mit einer Zähnezahl z3 = 20 ausgeführt.If, for example, as is proposed, the transmission ratio of the intermediate gear is carried out with i 1 > 1, preferably i 1 ≥ 4: 1, then the drive has a total transmission ratio i tot = i 1 xi 2 , ie in the present case i tot = 4/1 x 90/1 = 360/1. A gear ratio i 1 = 4/1 can be achieved, for example, with a number of teeth z 4 = 15 for the pinion 8 and a number of teeth z 5 = 60 for the internally toothed outer wheel 9. The planet gear 5 within the planetary gear 5, 1d, 2d is carried out in both embodiments, for example with a number of teeth z 3 = 20.

Sowohl das Planetengetriebe 5, 1d, 2d als auch das Zwischengetriebe 8, 9 (Figuren 1 und 2) sind in dem Düsenhalter 1 derart angeordnet und ausgestaltet, dass sämtliche Einbauteile von Flüssigkeit umströmt sind, so dass der gesamte Antrieb selbstreinigende Eigenschaften besitzt. Das gleiche gilt für die Lagerung des Düsenhalters 1 auf dem äußeren Lagerträger 2b über die Düsenhalterlager 6a und 6b und auch für die Lagerung der Turbinenwelle 3c im inneren Lagerträger 2c über die Turbinenlager 7a und 7b. Hier übernimmt die Reinigungsflüssigkeit sowohl reinigende als auch schmierende Funktion. Die gesamte erfindungsgemäße Vorrichtung kann in metallischer Ausführung hergestellt sein, wobei die zur Anwendung kommenden metallischen Werkstoffe sowohl gegen Reinigungsmittel beständig als auch mit dem notwendigen Gleit- und Reibverhalten ausgestaltet sein müssen. Die Konstruktion kann auch mittels geeigneter nichtmetallischer Werkstoffe, z.B. geeigneter Kunststoffe, ausgeführt werden. Darüber hinaus ist auch eine Kombination metallischer und nichtmetallischer Werkstoffe vorgesehen.Both the planetary gear 5, 1d, 2d and the intermediate gear 8, 9 (figures 1 and 2) are arranged and configured in the nozzle holder 1 such that all built-in parts are surrounded by liquid, so that the entire drive has self-cleaning properties. The same applies to the storage of the nozzle holder 1 on the outer bearing bracket 2b via the nozzle holder bearings 6a and 6b and also for the storage of the turbine shaft 3c in the inner bearing bracket 2c via the turbine bearings 7a and 7b. Here the cleaning liquid takes over both cleaning as well as lubricating function. The entire invention Device can be made in a metallic version, the application upcoming metallic materials both against cleaning agents consistently designed with the necessary sliding and friction behavior have to be. The construction can also be done using suitable non-metallic Materials, e.g. suitable plastics. Beyond that a combination of metallic and non-metallic materials is also provided.
