Beschreibung Description
Die Erfindung betrifft eine Reinigungsvorrichtung für Innenflächen von Tanks oder Fässern. Derartige Reinigungsvorrichtungen haben ein Gehäuserohr zum Anschließen an eine Flüssigkeitsleitung, einen in dem Gehäuserohr angeordneten Rotor, der im Betrieb von durch das Gehäuserohr strömender Reinigungsflüssig- keit angetrieben wird, ein an den Rotor angeschlossenes Planetengetriebe, einenThe invention relates to a cleaning device for the interior surfaces of tanks or barrels. Such cleaning devices have a housing tube for connection to a liquid line, a rotor arranged in the housing tube, which is driven during operation by cleaning fluid flowing through the housing tube, a planetary gear connected to the rotor
Sprühkopf, der an einem Ende des Gehäuserohrs angebracht und von dem Planetengetriebe angetrieben relativ zu dem Gehäuserohr drehbar beweglich ist, sowie einen Düsenträger, der drehbar beweglich an dem Sprühkopf angebracht ist und mehrere Düsen zum Versprühen von Reinigungsflüssigkeit trägt. Eine Reini- gungsvorrichtung mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen ist aus EP 3 065 876 B1 bekannt. Spray head, which is attached to one end of the housing tube and is rotatably movable relative to the housing tube, driven by the planetary gear, and a nozzle carrier, which is rotatably movable attached to the spray head and carries a plurality of nozzles for spraying cleaning liquid. A cleaning device with the features mentioned in the preamble of claim 1 is known from EP 3 065 876 B1.
Bei derartigen Reinigungsvorrichtungen wird Druck der Reinigungsflüssigkeit über einen Rotor und ein Planetengetriebe genutzt, um einen Sprühkopf in Rotation zu versetzen. Bei herkömmlichen Reinigungsvorrichtungen sind die Planetenräder des Planetengetriebes auf keramische Zapfen aufgesteckt, um einen möglichst verschleiß- und reibungsarmen Betrieb zu ermöglichen. In such cleaning devices, pressure of the cleaning liquid is used via a rotor and a planetary gear to rotate a spray head offset. In conventional cleaning devices, the planetary gears of the planetary gear are attached to ceramic pins in order to enable operation with as little wear and friction as possible.
Ständige Ziele bei der Entwicklung von Reinigungsvorrichtungen der eingangs genannten Art sind möglichst geringe Reibung, möglichst geringer Verschleiß, ein kompaktes Design und eine kostengünstige Fertigung. Aufgabe der vorliegenden Erfindung ist es, einen Weg aufzuzeigen, wie diese Ziele noch besser erreicht werden können. The constant goals in the development of cleaning devices of the type mentioned at the beginning are as little friction as possible, as little wear as possible, a compact design and cost-effective production. The object of the present invention is to show a way in which these goals can be achieved even better.
Diese Aufgabe wird durch eine Reinigungsvorrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen. This task is achieved by a cleaning device with the features specified in claim 1. Advantageous developments of the invention are the subject of subclaims.
In einer erfindungsgemäßen Reinigungsvorrichtung werden Planetenräder aus Kunststoff verwendet, die einstückig mit einem zwei Zapfen ausgebildet sind, bevorzugt beidseitig mit einem Zapfen. Anstelle eines separaten Zapfens aus Keramik, der in eine zentrale Öffnung der Planetenräder eingreift, werden erfindungsgemäß also Zapfen aus Kunststoff verwendet, die einstückig mit den Planetenrädern hergestellt werden. Vorteilhaft lassen sich so Gewicht und Fertigungskosten einsparen, ohne dass Reibung oder Verschleiß merklich erhöht werden. In a cleaning device according to the invention, planetary gears made of plastic are used, which are formed in one piece with a two pins, preferably with a pin on both sides. Instead of a separate pin made of ceramic, which engages in a central opening of the planet gears, according to the invention, pins made of plastic are used, which are made in one piece with the planet gears. Weight and manufacturing costs can be advantageously saved without noticeably increasing friction or wear.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass der Kunststoff ein Kunststoff auf Basis von Polyetheretherketon ist. Polyetheretherketon ist chemisch gegenüber allen gängigen Reinigungsflüssigkeiten auch bei höheren Temperaturen beständig und abriebfest. Dabei kann technisch reines Polyetheretherketon verwendet werden. Bevorzugt ist dem Polyetheretherketon Polytetrafluoräthylen beigemischt, beispielsweise 5 Gew.-% bis 20 Gew.-% Polytetrafluoräthylen. Auf diese Weise lässt sich die Verschließfestigkeit noch weiter erhöhen. An advantageous development of the invention provides that the plastic is a plastic based on polyetheretherketone. Polyetheretherketone is chemically resistant and abrasion-resistant to all common cleaning fluids, even at higher temperatures. Technically pure polyetheretherketone can be used. Polytetrafluoroethylene is preferably added to the polyetheretherketone, for example 5% by weight to 20% by weight of polytetrafluoroethylene. In this way, the sealing strength can be increased even further.

Die dargestellte Reinigungsvorrichtung dient zum Reinigen der Innenflächen von Tanks, Fässern oder ähnlichem durch Versprühen von Reinigungsflüssigkeit. Die in den Figuren 1 und 2 gezeigte Reinigungsvorrichtung hat ein Gehäuserohr 1 zum Anschließen an eine nicht gezeigte Flüssigkeitsleitung, über welche die Reinigungsvorrichtung mit Reinigungsflüssigkeit versorgt wird. In dem Gehäuserohr 1 ist ein Stator 2 angeordnet, der im Betrieb durch das Gehäuserohr 1 strömende Reinigungsflüssigkeit einem Rotor 15 zuführt, so dass der Rotor 15 im Betrieb von durch das Gehäuserohr 1 strömender Reinigungsflüssigkeit angetrieben wird. Der Rotor 15 ist über eine Rotorwelle 3 an ein Planetengetriebe 4 angeschlossen, das über eine Welle 5 einen Sprühkopf 6 antreibt, der drehbar beweglich an einem Ende des Gehäuserohrs 1 angebracht ist. An dem Sprühkopf 6 ist drehbar beweglich ein Düsenträger 7 angebracht, der mehrere Düsen 8 zum Versprühen von Reinigungsflüssigkeit trägt. Im Betrieb dreht sich der Sprühkopf 6 um eine erste Rotationsachse, die sich in Längsrichtung des Gehäuserohrs 1 erstreckt, und der Düsenträger 7 dreht sich um eine zweite Rotationsachse, die quer zu der ersten Rotationsachse, vorzugsweise senkrecht dazu, verläuft. The cleaning device shown is used to clean the interior surfaces of tanks, barrels or the like by spraying cleaning liquid. The cleaning device shown in Figures 1 and 2 has a housing tube 1 for connection to a liquid line, not shown, via which the cleaning device is supplied with cleaning liquid. A stator 2 is arranged in the housing tube 1 and, during operation, supplies cleaning fluid flowing through the housing tube 1 to a rotor 15, so that the rotor 15 is driven by cleaning fluid flowing through the housing tube 1 during operation. The rotor 15 is connected via a rotor shaft 3 to a planetary gear 4, which drives a spray head 6 via a shaft 5, which is rotatably attached to one end of the housing tube 1. A nozzle holder 7 is attached to the spray head 6 in a rotatable manner and carries several nozzles 8 for spraying cleaning liquid. During operation, the spray head 6 rotates about a first axis of rotation, which extends in the longitudinal direction of the housing tube 1, and the nozzle holder 7 rotates about a second axis of rotation, which runs transversely to the first axis of rotation, preferably perpendicular thereto.
Fig. 3 zeigt eine Explosionsdarstellung der Antriebsbaugruppe der Reinigungsvorrichtung. Diese Antriebsbaugruppe enthält den Rotor 15, der über die Rotorwelle 3 an das Planetengetriebe 4 angeschlossen ist. Das Planentengetriebe 4 ist bei dem gezeigten Beispiel ein dreistufiges Planetengetriebe. Jede Stufe enthält drei Planetenräder 41 . Die Planetenräder 41 sind aus Kunststoff, bevorzugt einem Kunststoff auf Basis Polyetheretherketon, einstückig mit Zapfen 42 hergestellt. Dem Kunststoff kann zur Verbesserung der Verschließfestigkeit Polytetrafluoräthylen beigemischt sein, beispielsweise 10 Gew.-% Polytetrafluoräthylen. Fig. 3 shows an exploded view of the drive assembly of the cleaning device. This drive assembly contains the rotor 15, which is connected to the planetary gear 4 via the rotor shaft 3. In the example shown, the planetary gear 4 is a three-stage planetary gear. Each stage contains three planet gears 41. The planet gears 41 are made of plastic, preferably a plastic based on polyetheretherketone, in one piece with pins 42. Polytetrafluoroethylene can be added to the plastic to improve the sealing strength, for example 10% by weight of polytetrafluoroethylene.
Die Planetenräder 41 einer Stufe des Planetengetriebes sind auf einer Scheibe 43 angeordnet, der Öffnungen aufweist, in denen Zapfen 42 der betreffenden Planetenräder stecken. Die Scheibe 43 kann beispielsweise aus Edelstahl oder Kunst- Stoff sein, insbesondere einem Kunststoff auf Basis von Polyetheretherketon, etwa Polyetheretherketon mit 5 Gew.-% bis 20 Gew.-% Polytetrafluoräthylen. The planet gears 41 of a stage of the planetary gear are arranged on a disk 43 which has openings in which pins 42 of the relevant planet gears are inserted. The disk 43 can be made of stainless steel or plastic, for example Be a material, in particular a plastic based on polyetheretherketone, such as polyetheretherketone with 5% by weight to 20% by weight of polytetrafluoroethylene.
Auf ihrer von der Scheibe 43 abgewandten Seite sind die Planetenräder 41 von einem Planetenträger 44, 45 gehalten, der ebenfalls Öffnungen aufweist, in denen die Zapfen 42 der betreffenden Planetenräder 41 stecken. Die Planetenräder 41 sind also jeweils zwischen einer der Scheiben 43 und einem Planetenträger 44, 45 angeordnet. Da die Planetenträger 44, 45 Scheiben sind, sind die Planetenräder also ersichtlich zwischen zwei Scheiben angeordnet. On their side facing away from the disk 43, the planet gears 41 are held by a planet carrier 44, 45, which also has openings in which the pins 42 of the relevant planet gears 41 are inserted. The planet gears 41 are each arranged between one of the disks 43 and a planet carrier 44, 45. Since the planet carriers 44, 45 are disks, the planet gears are clearly arranged between two disks.
Die Scheibe 43 und die Planetenträger 44, 45 weisen Öffnungen auf, in denen die Zapfen 42 der betreffenden Planetenräder 41 stecken, so dass die Scheiben 43 und die Planetenträger 44, 45 gemeinsam mit den Planetenrädern 41 der betreffenden Stufe um das entsprechende Sonnenrad 10, 11 , 12 umlaufen. The disk 43 and the planet carriers 44, 45 have openings in which the pins 42 of the relevant planet gears 41 are inserted, so that the disks 43 and the planet carriers 44, 45 together with the planet gears 41 of the relevant stage around the corresponding sun gear 10, 11 , 12 orbit.
Das Sonnenrad 10 der ersten Stufe des Planetengetriebes 4 ist an der Rotorwelle 3 angebracht oder beispielsweise einstückig mit ihr ausgebildet. Die Rotorwelle 3 ragt durch eine zentrale Öffnung der Scheibe 43 der ersten Getriebestufe hindurch, so dass das am Ende der Rotorwelle 3 angeordnete Sonnenrad 10 zwischen den Planetenrädern 41 der ersten Stufe des Planetengetriebes sitzt. Dieses erste Sonnenrad 10 und die Rotorwelle 3 können beispielsweise aus Edelstahl sein. The sun gear 10 of the first stage of the planetary gear 4 is attached to the rotor shaft 3 or, for example, formed in one piece with it. The rotor shaft 3 protrudes through a central opening in the disk 43 of the first gear stage, so that the sun gear 10 arranged at the end of the rotor shaft 3 sits between the planet gears 41 of the first stage of the planetary gear. This first sun gear 10 and the rotor shaft 3 can be made of stainless steel, for example.
Drehung der Rotorwelle 3 bewirkt somit, dass sich die Planetenräder 41 der ersten Stufe des Getriebes zusammen mit der Scheibe und dem Planetenträger 44, in deren Öffnungen die Zapfen 42 dieser Planetenräder stecken, um die geometrische Rotationsachse der Rotorwelle 3 drehen. Der Planetenträger 44 trägt dabei das Sonnenrad 11 der zweiten Getriebestufe, das durch eine zentrale Öffnung der angrenzenden Scheibe 43 hindurch gesteckt zwischen den Planetenrädern 42 der zweiten Getriebestufe angeordnet ist. Das Sonnenrad 11 kann dabei einstückig mit dem betreffenden Planetenträger 44 ausgebildet sein. Rotation of the rotor shaft 3 thus causes the planet gears 41 of the first stage of the transmission to rotate about the geometric axis of rotation of the rotor shaft 3 together with the disk and the planet carrier 44, in whose openings the pins 42 of these planet gears are inserted. The planet carrier 44 carries the sun gear 11 of the second gear stage, which is inserted through a central opening in the adjacent disk 43 and is arranged between the planet gears 42 of the second gear stage. The sun gear 11 can be formed in one piece with the planet carrier 44 in question.
In entsprechender Weise trägt die Scheibe 43 der zweiten Getriebestufe das Sonnenrad 12 der dritten Getriebestufe. Die Sonnenräder 11 , 12 sowie die Planeten- träger 44, 45 und die Scheiben 43 sind bei dem gezeigten Ausführungsbeispiel aus Edelstahl, können aber auch aus Kunststoff, insbesondere einem Kunststoff auf Basis von Polyetheretherketon hergestellt sein, beispielsweise einem Kunststoff, der 90 Gew.-% Polyetheretherketon und 10 Gew.- Polytetrafluoräthylen enthält. In a corresponding manner, the disk 43 of the second gear stage carries the sun gear 12 of the third gear stage. The sun gears 11, 12 and the planetary gears Carriers 44, 45 and the disks 43 are made of stainless steel in the exemplary embodiment shown, but can also be made of plastic, in particular a plastic based on polyetheretherketone, for example a plastic that contains 90% by weight of polyetheretherketone and 10% by weight of polytetrafluoroethylene .
Die Planetenräder 41 der letzten Stufe des Planetengetriebes sind zwischen einem Planetenträger 45 und einer Scheibe 43 gehalten, die ebenfalls Öffnungen aufweist, in denen Zapfen 42 dieser Planetenräder stecken. Der Planetenträger 45 43 kann die Welle 5 tragen, über die das Planetengetriebe 4 den Sprühkopf 6 antreibt. The planet gears 41 of the last stage of the planetary gear are held between a planet carrier 45 and a disk 43, which also has openings in which pins 42 of these planet gears are inserted. The planet carrier 45 43 can carry the shaft 5, via which the planetary gear 4 drives the spray head 6.
Das Planetengetriebe 4 ist einem Getriebegehäuse 13 angeordnet, dessen zylindrische Innenfläche das Hohlrad des Planetengetriebes bildet. Das Getriebegehäuse kann beispielsweise aus Edelstahl sein. Zwischen der Außenseite des Getriebegehäuses 13 und der Innenfläche des Rohrgehäuses 1 ist ein Ringspalt, durch den im Betrieb Reinigungsflüssigkeit zu dem Sprühkopf 6 strömt. Dabei kann ein Teil der Reinigungsflüssigkeit auch in dem Getriebegehäuse 13 durch das Platen- getriebe 4 hindurch zu dem Sprühkopf 6 fließen und dabei die Teile des Planetengetriebes 4 schmieren. Um diese Schmierung des Planetengetriebes zu unterstützen kann der Rotor 15 mehrere Durchgänge 16 für Reinigungsflüssigkeit aufwei- sen. The planetary gear 4 is arranged in a gear housing 13, the cylindrical inner surface of which forms the ring gear of the planetary gear. The gear housing can be made of stainless steel, for example. Between the outside of the gear housing 13 and the inner surface of the tubular housing 1 there is an annular gap through which cleaning fluid flows to the spray head 6 during operation. Part of the cleaning liquid can also flow in the gear housing 13 through the plate gear 4 to the spray head 6 and thereby lubricate the parts of the planetary gear 4. In order to support this lubrication of the planetary gear, the rotor 15 can have several passages 16 for cleaning fluid.
