Description

Die Erfindung betrifft ein in einen mit Flüssigkeit gefüllten Behälter mittels einer Hebevorrichtung an einer Führungseinrichtung absenkbares und aus dem Behälter hebbares Aggregat, das auf einem an der Führungseinrichtung auf- und abwärts bewegbaren Tragelement angeordnet ist und das während seines Betriebes innerhalb des Behälters eine aus der Flüssigkeit des Behälters gespeiste Strömung erzeugen kann wobei die Richtung der Strömung während des Betriebes durch maschinelle Verstellung verändert werden kann.The invention relates to a container filled with liquid by means of a Lifting device on a guide device that can be lowered and out of the container Liftable unit that moves up and down on the guide device Movable support element is arranged and that during its operation within of the container can generate a flow fed from the liquid of the container the direction of flow during operation by machine adjustment can be changed.

Durch die DE-C-195 17 901 ist ein der genannten Gattung angehörendes Aggregat vorbekannt. Dieses Aggregat besteht aus einem Tauchmotor-Rührwerk, welches in einem gasdichten Behälter an einer Führung höhenverstellbar angeordnet ist. Mit Hilfe einer außerhalb des Behälters befindlichen Bedienungseinrichtung kann die Arbeitsposition des eine Strömung erzeugenden Aggregates innerhalb des Behälters sowohl in der Höhe als auch durch eine Verdrehung der gesamten Führungseinrichtung in seiner die Richtung der Strömung bestimmenden Position verändert werden. Für Wartungszwecke wird das Aggregat an der Führungseinrichtung bis unter eine Abdichtung des Behälters hochgefahren, um dort inspiziert oder entnommen werden zu können. Für die mögliche Schwenkbewegung des Aggregates muß daher die Führungseinrichtung mit einer aufwendigen Abdichtung innerhalb der Abdeckung des Behälters gehalten werden.DE-C-195 17 901 is an aggregate of the type mentioned previously known. This unit consists of a submersible mixer, which in a gas-tight container on a guide is arranged adjustable in height. With help An operating device located outside the container can change the working position of the flow-generating unit within the container both in the height as well as by twisting the entire guide device in its the direction of the flow determining position can be changed. For maintenance purposes the unit on the guide device until under a seal of Container raised to be inspected or removed there. For the possible pivoting movement of the unit must therefore with the guide device an expensive seal held within the cover of the container become.

Die DE-C-40 15 478 lehrt ein Tauchmotor-Rührwerk mit einer einstellbaren Aufhängevorrichtung. Dazu findet eine Kupplung Verwendung, mit der eine Verbindung zwischen dem Tauchmotor-Rührwerk und einer an einer Aufhängevorrichtung geführten Befestigungseinrichtung hergestellt wird. Die Kupplungseinrichtung besteht aus einem Zapfen der Befestigungsvorrichtung, auf den eine am Tauchmotor-Rührwerk angebrachte Hülse aufgeschoben wird. Die Fixierung zwischen Zapfen und Hülse erfolgt durch einen Spreizbolzen, der in eine von mehreren Bohrungen eingesteckt wird. Durch die Anordnung von verschiedenen, nur in jeweils einer Position miteinander korrespondierenden Bohrungen ist die Möglichkeit zur starren Einstellung von unterschiedlichen Arbeitsstellungen des Tauchmotor-Rührwerkes gegeben.DE-C-40 15 478 teaches a submersible mixer with an adjustable suspension device. For this, a coupling is used with which a connection between the submersible mixer and one on a suspension device Fastening device is made. The coupling device consists of a Pin of the fastening device, on which one is attached to the submersible mixer Sleeve is pushed on. The pin and sleeve are fixed through an expansion bolt that is inserted into one of several holes. By the arrangement of different ones that correspond to each other in only one position Drilling is the possibility of rigidly setting different ones Working positions of the submersible mixer given.

Dies ist zwar vorteilhaft bei den verschiedenen Arbeiten an oder mit einem Rührwerk; es erfordert jedoch jedes Mal eine Betriebsunterbrechung, um eine andere Einstellung des Tauchmotor-Rührwerkes zu erhalten.Although this is advantageous for the various work on or with an agitator; however, it requires an interruption to a different setting each time of the submersible mixer.

Durch die DE-A 42 13 682 ist für ein Rührwerk ein Klinkenschaltwerk bekannt, mit dessen Hilfe ein Rührwerk in sehr langsamer Schwenkbewegung in vorgegebenen Schwenkgrenzen um eine Hochachse während des Betriebes geschwenkt werden kann. Ein solches Triebschaltwerk wirkt auf eine senkrecht innerhalb eines Behälters angeordnete Welle ein, an der das Rührwerk angeordnet ist. Durch das verwendete Triebschaltwerk wird zwar eine während eines Rührwerksbetriebes selbsttätig agierende Schwenkeinrichtung geschaffen; Veränderungen des Schwenkbereiches sind jedoch nur durch aufwendige manuelle Tätigkeiten möglich.From DE-A 42 13 682 a ratchet mechanism is known for an agitator with whose help an agitator in very slow swivel motion in predetermined Swing limits can be swiveled around a vertical axis during operation can. Such an engine switch acts vertically within a container arranged shaft on which the agitator is arranged. By the used Drive switch is one automatically during agitator operation operating swivel device created; Changes in the swivel range are however, this is only possible through complex manual activities.

Schließlich lehrt die DE-A-43 25 161 ein mittig in einem Behälter für feststoffhaltige Flüssigkeiten angeordnetes Rührwerk, das einen Propeller besitzt, welcher vorzugsweise durch einen Tauchmotor angetrieben wird. Dabei ist der Motor auf einem mit einer Welle fest verbundenen Halter befestigt. Die Welle ist wiederum mit einem oberhalb des Behälters angeordneten Schwenkantrieb verbunden. Durch den Schwenkantrieb wird eine Drehung der den Halter und den Motor mit Propeller tragenden Welle um 360° erzeugt. Nach Vollendung der 360°-Drehung kann eine Drehrichtungsumkehr bewirkt werden. In einer Variante dieser Ausführung ist vorgesehen, daß die horizontale Achse des Propellers seitlich versetzt zu der Drehachse der Welle verläuft. Dies führt zu einer durch die Rückstoßkraft des Propellers erzeugten permanenten Drehung der Welle.Finally, DE-A-43 25 161 teaches a center in a container for solids Liquids arranged agitator, which has a propeller, which preferably is powered by a submersible motor. The engine is on one with attached to a shaft firmly connected holder. The wave is again with one Swivel drive arranged above the container connected. By the Swivel drive is a rotation of the holder and the motor with propeller supporting shaft generated by 360 °. After completing the 360 ° rotation, a Reversal of rotation can be effected. In a variant of this embodiment, that the horizontal axis of the propeller laterally offset from the axis of rotation of the Wave runs. This results in one created by the recoil force of the propeller permanent rotation of the shaft.

Der Erfindung liegt die Aufgabe zugrunde, für Aggregate, die innerhalb eines Behälters angeordnet sind und darin eine aus der Flüssigkeit des Behälters gespeiste Strömung erzeugen, eine Schwenkvorrichtung zu entwickeln, mit deren Hilfe in einfacher Weise der Einsatz eines solchen Aggregates in den verschiedensten Behälterbauformen erfolgreich möglich ist.The invention has for its object for units that are within a container are arranged and therein a flow fed from the liquid of the container generate to develop a swivel device with the help of a simple manner the use of such a unit in a wide variety of container designs is successfully possible.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß der die Strömung erzeugende Teil des Aggregates an einem oder mehreren Drehgelenken befestigt ist, welche ihrerseits an dem Tragelement angeordnet sind und mit diesem auf- und abwärts bewegt werden können, wobei die maschinelle Verstellung des die Strömung erzeugenden Teils des Aggregates durch einen ebenfalls am Tragelement angeordneten Motor und/oder das durch das Aggregat erzeugte Moment erfolgen kann. The solution to this problem is, according to the invention, that the flow generating part of the unit is attached to one or more swivel joints, which in turn are arranged on the support element and up and with it can be moved down, the mechanical adjustment of the flow producing part of the unit by a likewise on the support element arranged motor and / or the torque generated by the unit can take place.

Mit Hilfe des Schwenkgelenkes, welches für die Aufnahme des Gesamtgewichtes des Aggregates und für die davon erzeugten Reaktionskräfte ausgelegt ist, kann in einfachster Weise mit Hilfe eines ebenfalls untergetaucht angeordneten Motors, beispielsweise eines elektrischen Getriebemotors, über ein Steuerkabel eine gewünschte Arbeitsstellung des Aggregates angesteuert werden. Dies erfordert kein Stillsetzen der Anlage und Lösen von verschmutzten Befestigungselementen, sondern es kann durch eine außerhalb des Behälters angeordnete Steuerung die Verschwenkung des Aggregates bewirkt werden. Es besteht sogar die Möglichkeit einer Fernsteuerung des Motors für einen teilweise oder voll automatisierten Betrieb des Rührwerkes. Auch kann mit Hilfe einer Videoüberwachung von einer Leitwarte aus das Aggregat ferngesteuert in eine solche Arbeitsposition geschwenkt werden, die mittels der erzeugten Strömung Feststoffansammlungen aufzulösen oder zu entfernen vermag. Damit ist auch die Voraussetzung für den Einbau eines solchen Aggregates in die unterschiedlichsten Behälterbauformen gegeben. Infolge der maschinellen Verstellung des Schwenkbereiches ist in einfachster Weise eine Anpassung an die jeweiligen Strömungssituationen möglich. Auch bei Verwendung eines Betätigungsgliedes, welches durch den Rückstoß des strömungserzeugenden Teiles des Aggregates betätigt wird, kann in einfacher Weise eine Verschwenkung des Aggregates erfolgen.With the help of the swivel joint, which is used to absorb the total weight of the Aggregates and designed for the reaction forces generated by them can be in easiest way with the help of a motor also submerged, for example, an electric geared motor, via a control cable desired working position of the unit can be controlled. This does not require Shut down the system and loosen dirty fasteners, but it can be pivoted by a control arranged outside the container of the unit. There is even the possibility of one Remote control of the engine for partially or fully automated operation of the Agitator. This can also be done with the help of video surveillance from a control room Unit can be remotely pivoted into such a working position by means of is able to dissolve or remove accumulations of solid matter from the generated flow. This is also the prerequisite for installing such a unit in the different container designs. As a result of the mechanical adjustment the swivel range is an adaptation to the respective in the simplest way Flow situations possible. Even when using an actuator, which is caused by the recoil of the flow-generating part of the unit is actuated, the unit can be pivoted in a simple manner.

Eine zweckmäßige Ausgestaltung der Erfindung sieht vor, daß das Drehgelenk oder die Drehgelenke über ein oder mehrere Zwischenglieder mit der Führungseinrichtung und/oder dem Aggregat verbunden sind.An expedient embodiment of the invention provides that the swivel or the Swivel joints via one or more intermediate links with the guide device and / or the unit are connected.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die Verstellung des die Strömung erzeugenden Teils des Aggregates über eine das Moment des Aggregates nutzende Betätigungseinrichtung erfolgt. Das Prinzip einer derartigen Verstellung ist von schwenkbaren Rasensprengern her bekannt. A further advantageous embodiment of the invention provides that the adjustment of the the flow generating part of the unit over a moment of Actuator using aggregates takes place. The principle of such Adjustment is known from swiveling lawn sprinklers.

Je nach Ausbildung der Zwischenglieder kann der Motor bzw. die Betätigungseinrichtung direkt mit dem Drehgelenk oder unter Zwischenschaltung von Übertragungselementen mit dem Drehgelenk verbunden sein.Depending on the design of the intermediate links, the motor or the Actuator directly with the swivel or with the interposition of Transmission elements connected to the swivel.

Im übrigen besteht die Möglichkeit, daß über jeweils eine Drehgelenkanordnung eine Verschwenkung des die Strömung erzeugenden Teils des Aggregates um seine Hochachse und/oder seine Querachse erfolgt. Somit kann die erzeugte Strömung nicht nur mit einem zur Wand des Behälters veränderlichen Winkel, sondern auch mit einem zum Boden des Behälters veränderbaren Winkel abgestrahlt werden.For the rest, there is the possibility that a Pivoting of the part of the unit generating the flow around its Vertical axis and / or its transverse axis takes place. So the generated flow cannot only with an angle that varies with the wall of the container, but also with one radiant angle to the bottom of the container are emitted.

Außerdem wird vorgeschlagen, daß das Tragelement zwei rechtwinklig zueinander angeordnete Schenkel besitzt, wobei an einem parallel zur Führungseinrichtung verlaufenden Schenkel ein oder mehrere Drehgelenke für den die Strömung erzeugenden Teils des Aggregates und an einem senkrecht zur Führungseinrichtung verlaufenden Schenkel der Motor oder die Betätigungseinrichtung angeordnet sind.It is also proposed that the support element two at right angles to each other has arranged legs, one parallel to the guide device extending leg one or more swivel joints for the flow generating part of the unit and on a perpendicular to the guide device extending leg of the motor or the actuator are arranged.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in following described in more detail.

Das Ausführungsbeispiel zeigt ein Strömungsaggregat 1, welches innerhalb eines Behälters 2 angeordnet ist. Das hier dargestellte Strömungsaggregat 1 verfügt über einen Propeller 3, der von einem Elektromotor 4 angetrieben wird und innerhalb des Behälters 2 in der vorhandenen Flüssigkeit eine Strahlströmung erzeugt. Die vom Strömungsaggregat 1 erzeugte Strahlströmung hält die innerhalb der Flüssigkeit befindlichen Feststoffe in der Schwebe und ist dazu geeignet, auf dem Boden des Behälters 2 vorhandene Ablagerungen aufzuwirbeln. Wird das Aggregat entlang einer an einer Behälterwand 5 befestigten Führungseinrichtung 6 mit Hilfe einer Hebevorrichtung 7 auf eine obere Position angehoben, so können auch auf der Flüssigkeitsoberfläche schwimmende Feststoffdecken mit Hilfe der Strahlströmung durchbrochen und aufgelöst werden. The embodiment shows a flow unit 1, which within a Container 2 is arranged. The flow unit 1 shown here has a propeller 3, which is driven by an electric motor 4 and within the Container 2 generates a jet flow in the existing liquid. The ones from Flow unit 1 generated jet flow keeps the within the liquid solids in the balance and is suitable on the bottom of the Swirl 2 existing deposits. If the unit runs along a on a container wall 5 attached guide device 6 with the help of a Lifting device 7 raised to an upper position, so can also on the Liquid surface floating solid ceilings with the help of the jet flow be broken and dissolved.

Die Führungseinrichtung 6 und die Hebevorrichtung 7 dienen im übrigen dazu, das Strömungsaggregat 1 in den Behälter 2 abzusenken und aus diesem zu heben. Das Strömungsaggregat 1 ist mit der Führungseinrichtung 6 durch ein Tragelement 8 verbunden.The guide device 6 and the lifting device 7 also serve the Lower the flow unit 1 into the container 2 and lift it out of it. The Flow unit 1 is with the guide device 6 through a support element 8 connected.

In der hier gewählten Darstellung befindet sich das Strömungsaggregat 1 in der untersten Absenkposition, die durch einen an der Führungseinrichtung 6 befestigten Anschlag 8.1 begrenzt wird. Das Tragelement 8 liegt im abgesenkten Zustand auf dem Anschlag 8.1 auf.In the illustration selected here, the flow unit 1 is in the lowermost lowering position, which is attached to the guide device 6 Stop 8.1 is limited. The support element 8 is in the lowered state on the Stop 8.1 on.

Das Tragelement 8 ist hier mehrteilig, es kann als Schweiß- oder Schraubkonstruktion ausgebildet sein. Die hier dargestellte Ausführung sieht zwischen dem Strömungsaggregat 1 und dem Tragelement 8 zwei Drehgelenke 9, 10 vor.The support element 8 is in several parts here, it can be a welded or screw construction be trained. The version shown here looks between the flow unit 1 and the support element 8 two swivel joints 9, 10 in front.

Das im Schnitt dargestellte Drehgelenk 9 besteht aus einem unteren Teil 9.1 und einem oberen Teil 9.2, es ermöglicht eine Relativbewegung um eine Hochachse 11. Damit kann das Strömungsaggregat 1 eine relativ zur Behälterwand 5 erfolgende Schwenkbewegung ausführen. Diese Schwenkbewegung wird durch eine am Tragelement 8 befestigte maschinelle Vorrichtung 12 vorgenommen, die hier durch einen elektrischen Antriebsmotor gebildet wird. Ein solcher Antriebsmotor ist analog dem Motor 4 des Strömungsaggregates 1 flüssigkeitsdicht ausgebildet.The hinge 9 shown in section consists of a lower part 9.1 and a upper part 9.2, it enables a relative movement about a vertical axis 11 the flow unit 1 can take place relative to the container wall 5 Carry out swiveling movement. This pivotal movement is by a Carrying element 8 attached mechanical device 12 made here by an electric drive motor is formed. Such a drive motor is analog the motor 4 of the flow unit 1 is liquid-tight.

Über eine Versorgungsleitung 13 ist die maschinelle Vorrichtung 12 mit einer Energiequelle verbunden, die je nach der Art der Vorrichtung 12 eine Stromquelle, eine Pneumatik- oder einer Hydraulikquelle sein kann. Über eine außerhalb des Behälters angeordnete Steuerung erfolgt eine gezielte Energiezufuhr zur Vorrichtung 12, die ein Verstellen des Strömungsaggregates 1 bewirkt. Die Steuerung ist an die Gegebenheiten des Behälters 2 und der von ihm aufgenommenen Flüssigkeit angepaßt. So kann zum Beispiel eine ununterbrochene Bewegung des Aggregates 1 über den gesamten verfügbaren Schwenkbereich oder eine jeweils um eine vorgegebene Winkelgröße erfolgende sukzessive Verschwenkung vorgenommen werden, wobei die Strahlströmung des Aggregates 1 jeweils mit einer vorgegebenen Dauer in eine eingestellte Richtung wirkt. Somit kann der vom Strömungsaggregat 1 erzeugte Flüssigkeitsstrom in jede beliebige Richtung gelenkt und mit einer den vorhandenen Erfordernissen entsprechenden Dauer aufrechterhalten werden. Somit können zum Beispiel Bereiche mit einer Neigung zu starken Ablagerungen einer besonders intensiven Reinigung unterzogen werden.The mechanical device 12 is connected to a supply line 13 Energy source connected, depending on the type of device 12, a power source, a Can be pneumatic or a hydraulic source. Via an outside of the container arranged control, a targeted energy supply to the device 12 takes place Adjusting the flow unit 1 causes. The control is based on the circumstances adapted to the container 2 and the liquid absorbed by it. So can for example an uninterrupted movement of the unit 1 over the entire available swivel range or a given angle size successive pivoting take place, the Jet flow of the unit 1 in each case with a predetermined duration set direction works. Thus, the liquid flow generated by the flow unit 1 steered in any direction and with an existing one Duration is maintained as required. Thus, for Example areas with a tendency to heavy deposits particularly undergo intensive cleaning.

Die im Ausführungsbeispiel gezeigte Anordnung der geradlinigen Kräfteübertragung zwischen der maschinellen Vorrichtung 12 und dem Drehgelenk 9 ist nicht zwingend. Anstelle der gezeigten Welle können ebenso gut Winkelgetriebe, Ketten- oder offene Riementriebe Verwendung finden. Die Wahl der Kraftübertragung wird im wesentlichen bestimmt von ihrer Funktionstauglichkeit für die jeweilige Anlage.The arrangement of the linear power transmission shown in the exemplary embodiment between the machine device 12 and the swivel joint 9 is not mandatory. Instead of the shaft shown, angular gears, chain drives or open drives can also be used Find belt drives. The choice of power transmission is essentially determined by their functionality for the respective system.

Das Ausführungsbeispiel zeigt die zusätzliche Verwendung eines gestrichelt dargestellten Drehgelenkes 10, welches eine Schwenkbewegung um eine senkrecht auf der Zeichenebene stehende Drehachse 14 ermöglicht. Damit kann das Strömungsaggregat auch um eine Querachse verschwenkt werden. Mit Hilfe des zweiten Drehgelenkes 10 wird ein weiterer Freiheitsgrad für die Bewegungsrichtung des Strömungsaggregates 1 geschaffen. Das Drehgelenk 10 ist hier verdeckt durch eine maschinelle Vorrichtung 15, die prinzipiell der maschinellen Vorrichtung 12 entspricht.The exemplary embodiment shows the additional use of a dashed line shown hinge 10, which has a pivoting movement about a perpendicular the axis of rotation 14 standing plane enables. So that can Flow unit can also be pivoted about a transverse axis. With the help of second hinge 10 is a further degree of freedom for the direction of movement Flow unit 1 created. The swivel joint 10 is covered here by a machine device 15, which corresponds in principle to the machine device 12.

Die Verwendung eines zweiten Drehgelenkes 10 erbringt eine Verbesserung der durch das Strömungsaggregat erreichbaren Leistung, da hiermit nahezu jeder Bereich des Behälters 2 von dem vom Strömungsaggregat 1 erzeugten Flüssigkeitsstrahl erreicht werden kann.The use of a second swivel joint 10 improves the through the flow unit achievable performance, since almost every area of the Container 2 reached by the liquid jet generated by the flow unit 1 can be.

Die Verwendung eines eine Verschwenkung um eine Querachse 14 ermöglichenden Drehgelenkes 10 ist jedoch nicht zwingend. In der überwiegenden Zahl der Anwendungsfälle ist ein um eine Hochachse schwenkendes Drehgelenk 9 völlig ausreichend. Statt des maschinell verstellbaren Drehgelenkes 10 kann an dieser Stelle auch ein fest einstellbares Gelenk vorgesehen werden, mittels dessen zum Beispiel eine bestimmte Winkelstellung der Strömung zum Boden des Behälters 2 vorgegeben wird.The use of a pivotal movement about a transverse axis 14 However, the pivot joint 10 is not mandatory. In the majority of use cases a swivel joint 9 pivoting about a vertical axis is completely sufficient. Instead of the mechanically adjustable swivel joint 10, a fixed one can also be used at this point adjustable joint can be provided, by means of which, for example, a specific one Angular position of the flow to the bottom of the container 2 is specified.
