Die Aufgabe wird erfindungsgemäß durch ein Rührwerk zum Mischen von Fluiden mit den Merkmalen das Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den jeweiligen Unteransprüchen angegeben.The object is achieved by an agitator for mixing fluids with the features of
Das erfindungsgemäße Rührwerk zum Mischen von Fluiden mit unterschiedlichen Viskositäten, wobei das Rührwerk ein bionisches Rührwerk ist, umfasst eine Hauptwelle mit einer Drehachse und Paddel. Die Paddel sind mit der Hauptwelle verbunden, wobei die Paddel jeweils eine Paddelwelle mit einer Paddelwellenachse aufweisen. Die Paddelwellenachsen weisen zur Drehachse einen ersten Winkel auf, welcher einen Wert zwischen 20° und 40° besitzt. Die Paddel sind mit ihren Paddelflächen in einem zweiten Winkel von 90° zueinander angeordnet. Im Betrieb des Rührwerks weisen die Paddel eine erste Rotation um die Hauptwelle und eine zweite Rotation um die jeweilige Paddelwellenachse auf. Ein bezogen auf die Drehachse radialer erster Abstand der Paddelwellenachsen an einem unteren Ende der Paddelwellen, welches von der Hauptwelle abgewandt ausgebildet ist, ist größer als ein, bezogen auf die Drehachse, radialer zweiter Abstand der Paddelwellenachsen an einem der Hauptwelle zugewandt ausgebildeten oberen Ende der Paddelwellen. Der Vorteil ist eine Schrägstellung der Paddel in einem von der Hauptwelle abgewandt ausgebildeten Bereich der Paddel nach Außen, so dass eine verbesserte Strömung im Fluid erzielt werden kann.The agitator according to the invention for mixing fluids having different viscosities, wherein the agitator is a bionisches agitator, comprises a main shaft with a rotation axis and paddle. The paddles are connected to the main shaft, the paddles each having a paddle shaft with a paddle shaft axis. The paddle shaft axes have a first angle to the axis of rotation, which has a value between 20 ° and 40 °. The paddles are arranged with their paddle surfaces at a second angle of 90 ° to each other. During operation of the agitator, the paddles have a first rotation about the main shaft and a second rotation about the respective paddle shaft axis. A radial first distance of the paddle shaft axes relative to the axis of rotation at a lower end of the paddle shafts, which is remote from the main shaft, is greater than one, relative to the axis of rotation, radial second distance of the paddle shaft axes on one of the main shaft facing the upper end of the paddle shafts. The advantage is an outward inclination of the paddles in a region of the paddles facing away from the main shaft, so that an improved flow in the fluid can be achieved.
Aus dem Stand der Technik ist eine Schrägstellung der Paddel im von der Hauptwelle abgewandt ausgebildeten Bereich der Paddel nach Innen, also eine der Drehachse zugewandt ausgebildete Stellung der Paddel bekannt. Bei gleicher Gestalt der Paddel führt die erfindungsgemäße Stellung der Paddel zu einem wesentlich größeren Umfangsradius aufgrund der nach Außen gerichteten Paddel, wodurch ein ebenfalls vergrößerter Strömungsradius erzielbar ist, der schließlich zu einer verbesserten Strömung des Fluids und damit zu einer verbesserten Durchmischung des Fluids führt. Gemäß der Erfindung ist die erste Rotation durch eine zwischen der Hauptwelle und den Paddel ausgebildete drehfeste Verbindung auf die Paddel übertragbar, und die zweite Rotation ist durch ein Wälzkörpergetriebe auf die Paddel übertragbar, wobei das Wälzkörpergetriebe zwischen der Hauptwelle und den Paddel ausgebildet ist. Die drehfeste Verbindung ist mit Hilfe von die Paddelwellen drehbar mit Hilfe von die Paddelwellen drehbar aufnehmenden zweiten Führungsrohren ausgebildet, welche drehfest mit der Hauptwelle verbunden sind. Zur Ausbildung der drehfesten Verbindung sind die zweiten Führungsrohre drehfest an einem Gehäuse aufgenommen, welches drehfest mit der Hauptwelle verbunden ist. Somit besteht die Möglichkeit die Führungsrohre am Gehäuse zu fixieren.From the prior art, an inclination of the paddles in the region of the paddles facing away from the main shaft to the inside, so a position of the paddle trained facing the axis of rotation is known. With the same shape of the paddle, the position of the paddles according to the invention leads to a substantially larger circumferential radius due to the outwardly directed paddles, whereby a likewise increased flow radius can be achieved, which ultimately leads to improved flow of the fluid and thus to improved mixing of the fluid. According to the invention, the first rotation is transferable to the paddles by a rotationally fixed connection formed between the main shaft and the paddle, and the second rotation is transferable to the paddles by a rolling element gear, the rolling element gear being formed between the main shaft and the paddles. The rotationally fixed connection is rotatably formed by means of the paddle shafts with the help of the paddle shafts rotatably receiving second guide tubes, which are rotatably connected to the main shaft. To form the rotationally fixed connection, the second guide tubes are non-rotatably accommodated on a housing, which is non-rotatably connected to the main shaft. Thus, it is possible to fix the guide tubes on the housing.

According to the invention, the Wälzkörpergetriebe is received in a transmission housing, whereby penetration of the fluid can be prevented and completely prevented by means of seals on the transmission housing.
Bevorzugt weisen die Paddelwellen Stabilisierungsrohre auf, welche Halteplatten aufweisen, und wobei die Stabilisierungsrohre mit Einkerbungen für weitere Passfedern der Paddelwellen ausgestaltet sind. Somit ist eine schnelle und passgenaue Montage möglich und die Paddel geraten während dem Betrieb nicht aus den vorgesehenen Winkeln bzw. nicht aus ihren vorgesehenen Positionen. Diese Befestigung kann auch durch Verschlüsse, Bolzen und andere mechanische Verschraubungsarten vorgenommen werden.Preferably, the paddle shafts on stabilizing tubes, which have holding plates, and wherein the stabilizing tubes are designed with notches for more feather keys of the paddle shafts. Thus, a quick and accurate installation is possible and the paddle advised during operation not from the intended angles or not from their intended positions. This attachment can also be made by closures, bolts and other mechanical Verschraubungsarten.
In einer weiteren Ausgestaltung des erfindungsgemäßen Rührwerks weisen die Paddelwellen an einem von dem Paddel abgewandt ausgebildeten Ende Passfedern für den Anschluss an Stabilisierungsrohre auf, wobei Halterungen der Paddel vorgesehen sind. Dadurch ist sichergestellt, dass die Stabilisierungsrohre der Paddel schnell montiert werden können und bei Bewegung der Paddel die Verbindung zwischen den Paddelwellen und den Stabilisierungsrohren der Paddel nicht verrutschen. Alternativ können aber alle möglichen Verschlüsse, Bolzen und mechanische Verschraubungen verwendet werden.In a further embodiment of the agitator according to the invention, the paddle shafts at a remote from the paddle end formed feather keys for connection to stabilizing tubes, wherein brackets of the paddles are provided. This ensures that the stabilizing tubes of the paddles can be mounted quickly and the paddle waves do not slip between the paddle shafts and the paddle stabilizing tubes as the paddles move. Alternatively, however, all sorts of closures, bolts and mechanical fittings can be used.
In einer weiteren Ausgestaltung des erfindungsgemäßen Rührwerks sind die Paddelwellen in zweiten Führungsrohren drehbar aufgenommen, wobei sie über Verstärkungen mit einem Übersetzungsgehäuse einer unteren Übersetzung verbunden sind, und wobei sie gegenüber dem Übersetzungsgehäuse mehrfach gelagert und abgedichtet sind. Der Vorteil ist, dass mit Hilfe der zweiten Führungsrohre eine verbesserte Stabilität und ein ruhiges Rührverhalten ausgebildet ist und gleichzeitig das Eindringen des Fluids in das Innere des unteren Übersetzungsgehäuses verhindert ist.In a further embodiment of the agitator according to the invention, the paddle shafts are rotatably received in second guide tubes, wherein they are connected via reinforcements with a transmission housing a lower translation, and wherein they are mounted and sealed against the translation housing multiple times. The advantage is that with the help of the second guide tubes improved stability and a quiet stirring behavior is formed and at the same time the penetration of the fluid is prevented in the interior of the lower transmission case.

Ein erfindungsgemäßes Rührwerk 1 zum Mischen von Fluiden, insbesondere ein bionisches Rührwerk, ist gem.
Alternativ kann auch Wasser oder ein Dampf-, Otto- oder anders gearteter Verbrennungsmotor eingesetzt werden. Der Antrieb 2 des bionischen Rührwerks 1 richtet sich nach der Viskosität und der Menge des Fluids, das bewegt respektive durchmischt werden muss sowie nach der Zielsetzung.Alternatively, water or a steam, gasoline or other kind of internal combustion engine can be used. The
Der Antrieb 2 ist mit einem Getriebe 3 gekoppelt, das wiederum eine Hauptwelle 4 des Rührwerks 1 antreibt, welche mit einer unteren Übersetzung 5 des Rührwerks 1 verbunden ist, s. insbesondere
Die Hauptwelle 4 ist mehrfach gelagert. Diese Mehrfachlagerung ermöglicht eine relativ reibungslose Rotation um ihre Drehachse 6. Des Weiteren dient die Mehrfachlagerung, da die Hauptwelle 4 das ganze Gewicht des Rührwerks 1 trägt, einer verbesserten Gewichtsverteilung auf die einzelnen Lager.The
Eine genaue Passung der Verbindung vom Getriebe 3 zur Hauptwelle 4 wird mittels einer Passfeder vorgenommen.An exact fit of the connection from the
Zur Montage des bionischen Rührwerks 1 ist eine Montageplatte 8 vorgesehen. Die Montageplatte 8 kann mittels hocheffizienten Schrauben, Dichtungen und Lagern mit der Vorrichtung, die zur Montage vorgesehen ist und die aus Holz, Beton, Stein, Kunststoff oder Metall bestehen kann, verbunden werden.For mounting the
In diesem Ausführungsbeispiel ist die Montageplatte 8 beispielsweise auf einen nicht näher dargestellten Deckel eines nicht näher dargestellten geschlossenen Raums, in dem sich das zu rührende Fluid befindet, angebracht. Durch diese Verbindung des bionischen Rührwerks 1 mit dem Deckel wird erstens eine Stabilität des bionischen Rührwerks 1 erzielt und zweitens verhindert, dass das Fluid austreten bzw. unerwünschtes Fluid in den Raum, in dem das Fluid gerührt wird, eintreten kann. Je nach Beschaffenheit des Deckels und des Fluids werden unterschiedliche Dichtungen und unterschiedliche Befestigungsvorrichtungen verwendet. Diese Bauweise ermöglicht einen schnellen Austausch der jeweiligen Komponenten und ermöglicht eine schnelle Inbetriebnahme des bionischen Rührwerks 1 beim Aufbau, der Wartung oder nach einer Reparatur.In this embodiment, the mounting
Die Montageplatte 8 ist fest mit einem Führungsrohr 9 verbunden, in dessen Inneren die Hauptwelle 4 zur unteren Übersetzung 5 verläuft, welche in einem unteren Übersetzungsgehäuse 10 aufgenommen ist. Das Führungsrohr 9 kann auch andere Formen als ein Rohr annehmen und das Material kann auch hier wieder variieren. Wichtig ist lediglich, dass es soweit dicht ist, dass das Fluid nicht ins Innere gelangt.The mounting
Am unteren Ende des Führungsrohrs 9, welches der unteren Übersetzung 5 zugewandt positioniert ist, ist dieses mit einem Anschluss 11 mit der unteren Übersetzung 5 gekoppelt, die drehbar ist. Auch hier gilt wieder, dass die Verbindung soweit dicht sein muss, dass kein Fluid ins Innere gelangt und dass das untere Übersetzungsgehäuse 10 drehbar ist. Beide Anforderungen werden durch unterschiedliche Dichtungen und Lagerungen erreicht.At the lower end of the
In dem Übersetzungsgehäuse 10 befindet sich das vom Antrieb 2 abgewandt ausgebildete Ende 12 der Hauptwelle 4, die mit dem Übersetzungsgehäuse 10 über eine gelagerte Halterung 13 verbunden ist. Durch die Rotation der Hauptwelle 4 wird auch das Übersetzungsgehäuse 10 in Rotation versetzt, so dass sich der gesamte untere Teil des bionischen Rührwerks 1 um die Drehachse 6 der Hauptwelle 4 dreht. Mit anderen Worten bedeutet dies, dass die Hauptwelle 4 drehfest mit dem Übersetzungsgehäuse 10 verbunden ist.In the
Im Übersetzungsgehäuse 10 sind Kegelräder 14 aufgenommen, die ein dem Antrieb 2 zugewandt ausgebildetes Ende von Paddelwellen 15 markieren. Wie
Die Kegelräder 14 werden vom kegelförmigen Antriebszahnrad 16 der Hauptwelle 4 angetrieben. Aufgrund der Verbindung, d.h. drehfesten Verbindung der Kegelräder 14 mit der ihnen jeweils zugeordneten Paddelwelle 15, werden die Paddelwellen 15 in Rotation versetzt.The bevel gears 14 are driven by the
Der durch die Kegelräder 14 und dem Antriebszahnrad 16 ausgebildeter Antrieb der Paddelwellen 15 im Übersetzungsgehäuse 10 kann auch mittels eines Zahnriemenantrieb, Drehgelenkantrieb, Riemenantrieb, Kettenantrieb, Magneten und anderen hergestellt sein.The trained by the bevel gears 14 and the
Wichtig ist, dass das Übersetzungsgehäuse 10 soweit abgedichtet ist, dass kein Fluid ins Innere gelangt und das die im Fluid erzeugte Strömung nicht durch die Größe und Form des Übersetzungsgehäuses 10 beeinträchtigt wird.It is important that the
An einer Unterseite 17 des Übersetzungsgehäuses 10, welche vom Antrieb 2 abgewandt ausgebildet ist, sind zweite Führungsrohre 18 der Paddelwellen 15 ausgebildet, wobei je ein zweites Führungsrohr 18 eine Paddelwelle 15 zumindest teilweise umfasst.On an
Mittels Verstärkungen 19, welche an der Unterseite 17 ausgebildet sind, sind die zweiten Führungsrohre 18 an dem Übersetzungsgehäuse 10 befestigt. Diese Verstärkungen 19 sorgen für eine größerer Stabilität und eine ruhige und gleichmäßige Bewegung von an den Paddelwellen 15 befestigten Paddel 20. Wie insbesondere
Die Paddelwellen 15 sind in den ihnen jeweils zugeordneten zweiten Führungsrohren 18 aufgenommen und sind mehrfach gelagert. Gleichzeitig sind sie mehrfach abgedichtet, damit kein Fluid in das Innere des Übersetzungsgehäuses 10 eindringen kann. An dieser Stelle sei erwähnt, dass die genannten Abdichtungen in Form von geeigneten Gummidichtungen oder Metalldichtungen ausgebildet sein können. Hierbei ist insbesondere das zu durchmischende Fluid zu berücksichtigen, und zu beachten, inwieweit eine korrosive und/oder fressende Neigung des Fluids gegenüber dem Material der eingesetzten Dichtungen besteht.The
An einem unteren Ende 21 der Paddelwellen 15, welche vom Übersetzungsgehäuse 10 bzw. von der Hauptwelle 4 abgewandt ausgebildet ist, sind diese mit weiteren Passfedern 22 für den Anschluss an Stabilisierungsrohre 23 und Halterungen in Form von Halteplatten 24 der Paddel 20 versehen. Die weiteren Passfedern 22 sorgen dafür, dass die Stabilisierungsrohre 23 der Paddel 20 schnell montiert werden können und bei Bewegung der Paddel 20 die Verbindung zwischen der Paddelwelle 15 und dem jeweiligen Stabilisierungsrohr 23 nicht verrutscht bzw. nicht gelöst wird.At a
Wie insbesondere
Die Stabilisierungsrohre 23 sind mit den Halteplatten 24, die mit nicht näher dargestellten Einkerbungen für die weitere Passfedern 22 versehen sind, an die Paddelwellen 15 montiert. Diese Befestigung kann auch durch Verschlüsse, Bolzen und andere mechanische Verschraubungsarten vorgenommen werden.The stabilizing
Die Stabilisierungsrohre 23 der Paddel 20 dienen als Halterungen der Paddel 20, sie geben dem jeweiligen Paddel 20 eine zusätzliche Stabilität und verhindern zudem eine Verdrehung von Paddelaußenflächen 25 der Paddel 20. Mit anderen Worten bedeutet dies, dass die Stabilisierungsrohre 23 die Paddel 20 in ihrer Position relativ zueinander und relativ zur Hauptwelle 4 stabilisieren, so dass eine Depositionierung verhindert wird und Winkel bzw. Winkellagen, wie unten erläutert wird, erhalten bleiben.The stabilizing
Die Paddel 20 sind mit Metallwinkel 26 zur Verstärkung und Strömungsbesserung der Paddel 20 versehen. Auch sind Paddelränder 27 der Paddel 20 umgeschlagen, um ebenfalls das Strömungsverhalten der Paddel 20 zu verbessern.The paddles 20 are provided with
Form, mit anderen Worten Außenkonturen, und Größe der Paddel 20 richten sich nach dem Fluid sowie der Menge des Fluids, das umgewälzt werden muss. Zum Einsatz kommen folgende Formen für die Paddel 20: Rund, Oval, Dreieck, Trapez, Raute, Rhombus, Parallelogramm, Quadrat, Rechteck, Viereck und natürliche Formen aus dem Tierreich und der Natur. Gleichzeitig kann das Paddel 20 gebogen oder verformt werden, wenn dies der Stabilität der Paddel 20 dient und/oder das Strömungsverhalten des Fluids positiv beeinflusst. Das Paddel 20 ist wie in den
Die Paddelwellen 15 mit ihren Wellenachsen 28 und in axialer Verlängerung die Paddel 20 mit ihren koaxialen Paddelachsen 29 sind in einem ersten Winkel α von 20° bis 40° zur Hauptwelle 4 positioniert, damit ein ideales Strömungsverhalten des Fluids erzeugt wird.The
Die Paddel 20 sind so an den Paddelwellen 15 anzubringen, dass die Paddelflächen 30 in einem zweiten Winkel β von 90° zueinander stehen, wie insbesondere
Durch die Drehungen der Paddel 20, das heißt durch eine erste Rotation der Paddel 20 um die Drehachse 6 und durch eine zweite Rotation der jeweiligen Paddel 20 um die ihnen zugeordnete Paddelwellenachse 28, wird das Fluid von den Paddels 20 vor sich hergeschoben beziehungsweise verdrängt. Die dadurch erzeugte Bewegung sorgt dafür, dass das Fluids um 360° verschoben wird, was wiederum zur Folge hat, dass die Bestandteile des Fluids vollständig durchmischt werden und das Fluid so maximal homogen wird.As a result of the rotations of the paddles 20, that is to say by a first rotation of the paddles 20 about the axis of
Bei dieser Bewegung des Fluids werden Turbulenzen soweit als möglich reduziert und Scherkräfte vermieden. Dadurch ist eine wesentlich bessere Durchmischung des Fluids realisiert. Gleichzeitig hat die Bewegung der Paddel 20 und die im Fluid erzeugte Bewegung zur Folge, dass wesentlich weniger Energie aufgewendet werden muss, um das Fluid in Bewegung zu halten, als dies bei herkömmlichen Rührwerken der Fall ist. Ein weiterer Vorteil dieser Art des Rührens besteht darin, dass mögliche in dem Fluid enthaltenen Feststoffe sich nicht um die Paddel 20 oder Verbindungen, das heißt die Paddelwellen 15, die Halteplatten 24 und die Stabilisierungsrohre 23, wickeln.With this movement of the fluid turbulences are reduced as much as possible and shear forces are avoided. As a result, a much better mixing of the fluid is realized. At the same time, the movement of the paddles 20 and the movement generated in the fluid result in much less energy being required to keep the fluid in motion than conventional agitators. Another advantage of this type of agitation is that any solids contained in the fluid do not wrap around the paddles 20 or joints, that is, the
Die
Das Rührwerk 1 ist in verschiedensten Größen und Ausführungen für die verschiedensten Einsätze, in denen Fluide umgewälzt bzw. durchmischt werden, gefertigt und angeboten. Beispielsweise kann es sich hierbei um Einsätze in der Landwirtschaft (wie Biogasanlagen mit und ohne Gashauben, Güllekasten, Milchkühlung, etc.), der Industrie (wie Emulsionsbecken, Rührtechniken in Laboren, etc.), der Lebensmittelindustrie (wie Limonaden- und Fruchtsafthersteller, Molkereien, Brauereien, etc.), in Gemeinden und Kommunen (Kläranlagen, Trinkwasseraufbereitung, stehenden Gewässern, etc.) und noch vielem mehr handeln.The
Das bionische Rührwerk kann aus jeglichen Holz-, Kunststoff-, Karbon-, Metallarten und aus anderen bestehenden Materialien gefertigt werden. Die Verbindungen, insbesondere die Paddelwellen 15, die Halteplatten 24 und die Stabilisierungsrohre 23, welche die Bauteile des bionischen Rührwerks verbinden, sind immer abhängig von Art und Beschaffenheit des Materials, aus dem das Rührwerk gebaut wird. Dementsprechend können die Verbindungen geschraubt, geklebt, gesteckt, oder vernietet sein.The bionic agitator can be made of any type of wood, plastic, carbon, metal and other existing materials. The connections, in particular the
