Description

Die Erfindung betrifft eine Anordnung zur Durchmischung eines Medium mit einem Element zur Erzeugung einer Bewegung in dem Medium, wobei das Element mit einem Antrieb in Verbindung steht.The invention relates to an arrangement for mixing a medium with an element for generating a movement in the medium, the element being connected to a drive.

Mischen ist eine Grundoperation in der mechanischen Verfahrenstechnik. Anordnungen zur Durchmischung kommen bei mischtechnischen VorgƤngen zum Einsatz, bei denen Bestandteile von mindestens zwei getrennt vorliegenden Komponenten durch Relativbewegung so umpositioniert werden, dass ein neues Anordnungsschema entsteht.Mixing is a basic operation in mechanical process engineering. Arrangements for mixing are used in mixing processes, in which components of at least two separately available components are repositioned by relative movement in such a way that a new arrangement scheme is created.

HƤufig liegt dabei eine Hauptphase als kontinuierliche Phase vor wƤhrend eine Zusatzphase anfangs diskontinuierlich vorhanden ist. Je nachdem in welchem Aggregatzustand die Phasen vorliegen spricht man bei dem Mischvorgang auch von Homogenisieren, Suspendieren, Emulgieren oder Begasen. Unter Homogenisieren versteht man das Vermischen von Gasen oder ineinander lƶslicher FlĆ¼ssigkeiten. Als Suspendieren bezeichnet man das Verteilen fester Teilchen in FlĆ¼ssigkeiten. Emulgieren ist das Verteilen von FlĆ¼ssigkeitstrƶpfchen in FlĆ¼ssigkeiten. Beim Begasen werden Gasblasen in FlĆ¼ssigkeiten verteilt.Often there is a main phase as a continuous phase while an additional phase is initially discontinuous. Depending on the physical state of the phases, the mixing process is also referred to as homogenizing, suspending, emulsifying or gassing. Homogenization is the mixing of gases or liquids that are soluble in one another. Suspending is the distribution of solid particles in liquids. Emulsifying is the distribution of liquid droplets in liquids. Gas bubbles are distributed in liquids during gassing.

Anordnungen zum Durchmischen von Medien sind beispielsweise aus der US 5,957,759 A und der US 5,664,990 A bekannt. Diese sind mit einer RĆ¼hr- oder UmwƤlzeinrichtungen ausgestattet, um beispielsweise Dispersionen herzustellen.Arrangements for mixing media are for example from the US 5,957,759 A and the US 5,664,990 A known. These are equipped with a stirring or circulating device, for example to produce dispersions.

Die DE 25 48 754 A1 beschreibt ein Verfahren und eine Vorrichtung zum Einbringen von Luft in FlĆ¼ssigkeiten, insbesondere fĆ¼r die AbwasserbelĆ¼ftung. Die zu belĆ¼ftende FlĆ¼ssigkeit wird dazu unter Druck einer Wasserstrahlpumpe zugefĆ¼hrt. Durch den in der Wasserstrahlpumpe erzeugten Unterdruck wird Luft angesaugt, die sich dann mit der zu belĆ¼ftenden FlĆ¼ssigkeit vermischt.The DE 25 48 754 A1 describes a method and a device for introducing air into liquids, in particular for wastewater aeration. For this purpose, the liquid to be aerated is fed under pressure to a water jet pump. The vacuum created in the water jet pump draws in air, which then mixes with the liquid to be aerated.

In der Verfahrens- und Abwassertechnik werden hƤufig RĆ¼hrwerke eingesetzt. Ein besonders geeignetes Verfahren zur UmwƤlzung von FlĆ¼ssigkeitsvolumen besteht im Einsatz von TauchrohrrĆ¼hrwerken, welche einen Motor aufweisen, der einen Propeller antreibt, wobei der Motor vollstƤndig in die FlĆ¼ssigkeit eingetaucht arbeitet.Agitators are often used in process and wastewater engineering. A particularly suitable method for circulating liquid volumes consists in the use of immersion tube agitators, which have a motor that drives a propeller, the motor working completely immersed in the liquid.

TauchrohrrĆ¼hrwerke bewirken eine Verteilung von Schmutzteilchen, Gasen oder anderen Stoffen in einem Becken, indem durch die Propellerhydraulik sehr groƟe ImpulskrƤfte bei niedrigem Energieeintrag Ć¼bertragen werden und dadurch die Suspension total durchmischen.Immersion tube agitators distribute dirt particles, gases or other substances in a pool by transferring very large impulse forces with low energy input through the propeller hydraulics and thereby totally mixing the suspension.

In der DE 10 2010 014 239 A1 wird eine Vorrichtung zur Durchmischung eines Medium beschrieben. Die Anordnung ist in einem Becken zur Herstellung von Biogas positioniert und umfasst RĆ¼hrwerke, die Ć¼ber einen Propeller verfĆ¼gen, welcher von einem Motor angetrieben werden, der vollstƤndig in die FlĆ¼ssigkeit eintaucht.In the DE 10 2010 014 239 A1 describes a device for mixing a medium. The assembly is positioned in a biogas production basin and includes agitators that have a propeller driven by a motor that is fully immersed in the liquid.

Die US 3,782,699 zeigt eine RĆ¼hr- und Heizvorrichung mit einem BimetallrĆ¼hrer. Sie offenbart eine Anordnung entsprechend dem Oberbegriff des Anspruchs 1 und ein Verfahren mit einigen Merkmalen des Anspruchs 12.The US 3,782,699 shows a stirring and heating device with a bimetal stirrer. It discloses an arrangement according to the preamble of claim 1 and a method with some features of claim 12.

Die JP S58-24327A beschreibt eine RĆ¼hrvorrichtung mit FormgedƤchtniselementen, die durch einen Temperaturgradienten eines Mediums angetrieben wird.The JP S58-24327A describes a stirring device with shape memory elements, which is driven by a temperature gradient of a medium.

Aufgabe der Erfindung ist es, eine Anordnung zur Durchmischung anzugeben, die weitgehend unabhƤngig von herkƶmmlichen Energiequellen arbeiten kann. Weiterhin soll ein Verfahren zur Durchmischung eines Mediums angegeben werden, das auch ohne aufwendige Infrastruktur bzw. ohne lange Versorgungsleitung betrieben werden kann. Auch soll sich die Anordnung zur Durchmischung durch eine lange Lebensdauer, eine zuverlƤssige Arbeitsweise und mƶglichst geringen Anschaffungs- bzw. Betriebskosten auszeichnen.The object of the invention is to provide an arrangement for thorough mixing which can work largely independently of conventional energy sources. Farther a method for mixing a medium is to be specified that can also be operated without complex infrastructure or without a long supply line. The arrangement for thorough mixing should also be distinguished by a long service life, reliable operation and the lowest possible acquisition or operating costs.

Diese Aufgabe wird erfindungsgemƤƟ durch eine Anordnung mit den Merkmalen des Anspruchs 1 bzw. einem Verfahren mit den Merkmalen des Anspruchs 12 gelƶst.This object is achieved according to the invention by an arrangement with the features of claim 1 or a method with the features of claim 12.

Bevorzugte Varianten sind in den UnteransprĆ¼chen, der Beschreibung und der Zeichnung zu entnehmen.Preferred variants can be found in the subclaims, the description and the drawing.

ErfindungsgemƤƟ weist der Antrieb ein Material zur DurchfĆ¼hrung einer thermischen Ƅnderung seiner geometrischen Abmessung auf. Durch WƤrmeentwicklung dehnt sich das Material aus oder zieht sich zusammen. Aufgrund der WƤrmeausdehnung bzw. WƤrmeschrumpfung Ƥndert sich die LƤnge, der FlƤcheninhalt bzw. das Volumen des Kƶrpers, der aus diesem Material gefertigt ist.According to the invention, the drive has a material for carrying out a thermal change in its geometric dimension. The material expands or contracts due to the development of heat. Due to the thermal expansion or heat shrinkage, the length, the area or the volume of the body, which is made of this material, changes.

ErfindungsgemƤƟ steht das Material mit dem Element der derart in Verbindung, dass die Ƅnderungen der geometrischen Abmessungen des Materials eine FormƤnderung des Elements hervorrufen. Diese FormƤnderung des Elements fĆ¼hrt zur Durchmischung des Mediums.According to the invention, the material is connected to the element in such a way that the changes in the geometric dimensions of the material cause a change in shape of the element. This change in shape of the element leads to the mixing of the medium.

Bei einer besonders gĆ¼nstigen Variante der Erfindung handelt es sich bei dem Material um eine FormgedƤchtnislegierung. FormgedƤchtnislegierungen (englisch: Shape Memory Alloy, AbkĆ¼rzung: SMA) sind spezielle Metalle, die in zwei unterschiedlichen Kristallstrukturen existieren kƶnnen. Sie werden oft auch als Memory-Metalle bezeichnet. Dies rĆ¼hrt von dem PhƤnomen, dass sie sich an eine frĆ¼here Formgebung trotz nachfolgender starker Verformung zu erinnern scheinen.In a particularly favorable variant of the invention, the material is a shape memory alloy. Shape memory alloys (English: Shape Memory Alloy, abbreviation: SMA) are special metals that can exist in two different crystal structures. They are often referred to as memory metals. This is due to the phenomenon that they seem to remember an earlier shape despite subsequent severe deformation.

Vorzugsweise wird als Material eine Nickel-Titan-Legierung eingesetzt. Diese zeichnen sich durch besonders groƟe Effekte bei gleichzeitig hoher Festigkeit aus. Bei TemperaturƤnderung vollzieht sich ein PhasenĆ¼bergang.A nickel-titanium alloy is preferably used as the material. These are characterized by particularly large effects combined with high strength. A phase transition occurs when the temperature changes.

Bei einer besonders gĆ¼nstigen Variante der Erfindung weist der Antrieb zudem ein Material zur Oxidation auf. Vorzugsweise handelt es sich dabei um ein katalytisches Material, wobei sich insbesondere ein platinhaltiges Material eignet. Bei einer Variante der Erfindung werden Nanopartikel von Platin eingesetzt. Diese werden bei einer besonders bevorzugten AusfĆ¼hrungsform der Erfindung auf winzigen Rƶhren aus Kohlenstoff aufgetragen.In a particularly favorable variant of the invention, the drive also has a material for oxidation. It is preferably a catalytic material, a platinum-containing material being particularly suitable. In a variant of the invention, nanoparticles of platinum are used. In a particularly preferred embodiment of the invention, these are applied to tiny tubes made of carbon.

Das Material kommt mit mindestens einem Stoff in Kontakt, der mit Sauerstoff in einer katalytischen Reaktion umgesetzt wird. Bei den Stoffen kann es sich beispielsweise um Wasserstoff oder organische Verbindungen wie beispielsweise Methanol handeln. Bei einer Variante der Erfindung werden als Stoffe organische Verbindungen eingesetzt, die im Wasser gelƶst sind. Dabei kann es sich beispielsweise um Zucker oder Kohlenhydrate wie zum Beispiel StƤrke handeln. Insbesondere verschmutzte GewƤsser weisen hƤufig eine Vielzahl an organischen Substanzen auf, welche sich als Stoffe fĆ¼r eine oxidative Umsetzung eignen.The material comes into contact with at least one substance that is reacted with oxygen in a catalytic reaction. The substances can be, for example, hydrogen or organic compounds such as methanol. In a variant of the invention, organic compounds which are dissolved in water are used as substances. This can be, for example, sugar or carbohydrates such as starch. Polluted waters in particular often have a large number of organic substances which are suitable as substances for an oxidative reaction.

Durch die exotherme oxidative Umsetzung wird WƤrme freigesetzt, die an das Material zur DurchfĆ¼hrung einer thermischen Ƅnderung Ć¼bertragen wird. Durch den Temperaturanstieg Ƥndern sich die geometrischen Abmessungen und es kommt zu einer LƤngen-, FlƤchen- bzw. VolumenƤnderung, die zu einer FormƤnderung des Elements fĆ¼hren.The exothermic oxidative reaction releases heat, which is transferred to the material to carry out a thermal change. Due to the temperature increase, the geometric dimensions change and there is a change in length, area or volume, which leads to a change in shape of the element.

Bei einer besonders gĆ¼nstigen Variante der Erfindung ist das fĆ¼r die Oxidation verantwortliche Material um das Material angeordnet, welches eine thermische Ƅnderung der geometrischen Abmessung durchfĆ¼hrt. Beispielsweise kann das Material zur thermischen Ƅnderung stabartig, vorzugsweise in Form eines Zylinders, ausgebildet sein. Um diesen stabartigen Kƶrper ist dann das Katalysatormaterial angeordnet, wobei dieses vorzugsweise einen hohlzylindrischen Kƶrper bildet. An der ƤuƟeren, ringfƶrmigen KatalysatorhĆ¼lle lƤuft die exotherme Oxidationsreaktion ab und Ć¼bertrƤgt die WƤrme an den inneren Kern, der eine LƤngenƤnderung aufgrund des Temperaturanstiegs durchfĆ¼hrt.In a particularly favorable variant of the invention, the material responsible for the oxidation is arranged around the material which carries out a thermal change in the geometric dimension. For example, the material for thermal change can be rod-shaped, preferably in the form of a cylinder. The catalyst material is then arranged around this rod-like body, this preferably forming a hollow cylindrical body. The exothermic oxidation reaction takes place on the outer, annular catalyst shell and transfers the heat to the inner core, which carries out a change in length due to the temperature rise.

Bei einer besonders vorteilhaften Variante der Erfindung besteht das Element zumindest teilweise aus einem elastischen Material. Vorzugsweise eignet sich ein gummielastisches Material. Beispielsweise kann das Element aus einem Silikonkautschuk oder einem Silikonelastomer bestehen. Somit ist das Element elastisch verformbar.In a particularly advantageous variant of the invention, the element consists at least partially of an elastic material. A rubber-elastic material is preferably suitable. For example, the element can consist of a silicone rubber or a silicone elastomer. The element is thus elastically deformable.

Bei einer besonders gĆ¼nstigen AusfĆ¼hrung der Erfindung weist das Element einen sichelfƶrmigen Querschnitt auf. Das Element ist vorzugsweise als glockenfƶrmiger Kƶrper ausgebildet.In a particularly favorable embodiment of the invention, the element has a crescent-shaped cross section. The element is preferably designed as a bell-shaped body.

Das Element steht bei einer vorteilhaften Variante der Erfindung Ć¼ber ein Verbindungselement mit dem Antrieb in Wirkverbindung. Bei dem Verbindungselement kann es sich beispielsweise um einen Draht handeln, der an dem Element angebracht ist und bei einer Kontraktion eines Materials des Antriebs das Element in eine Richtung verformt, sodass Medium gefƶrdert wird. Bei einer besonders gĆ¼nstigen Variante ist das Verbindungselement zumindest teilweise in dem Element angeordnet. So kann ein als Draht ausgebildetes Verbindungselement in der elastischen Masse, aus der das Element besteht, eingebettet sein.In an advantageous variant of the invention, the element is operatively connected to the drive via a connecting element. The connecting element can be, for example, a wire which is attached to the element and, when a material of the drive contracts, deforms the element in one direction, so that medium is conveyed. In a particularly favorable variant, the connecting element is at least partially arranged in the element. A connecting element designed as a wire can thus be embedded in the elastic mass from which the element consists.

Bei einer besonders gĆ¼nstigen AusfĆ¼hrung der Erfindung weist die Anordnung zur Durchmischung ein RĆ¼ckstellelement auf, welches nach einer Verformung des Elements durch den Antrieb das Element zurĆ¼ckverformt.In a particularly favorable embodiment of the invention, the arrangement for mixing has a restoring element which, after the element has been deformed by the drive, deforms the element back.

WƤhrend einer ersten Phase kommt es zu einer thermischen Ƅnderung eines Materials des Antriebs, die zu einer FormƤnderung des Elements fĆ¼hrt. In einer zweiten Phase sorgt das RĆ¼ckstellelement dafĆ¼r, dass das Element in seine Ausgangsposition zurĆ¼ckkehrt.During a first phase, there is a thermal change in a material of the drive, which leads to a change in the shape of the element. In a second phase, the reset element ensures that the element returns to its starting position.

Die zuvor beschriebenen Phasen wiederholen sich zyklisch.The phases described above are repeated cyclically.

Bei dem RĆ¼ckstellelement kann es sich beispielsweise um ein Federelement handeln, die als RĆ¼ckstellfeder fungiert, insbesondere ein Blattfederelement.The restoring element can be, for example, a spring element that functions as a restoring spring, in particular a leaf spring element.

Bei einer Variante der Erfindung ist das RĆ¼ckstellelement in das Element integriert. Beispielsweise kann eine RĆ¼ckstellfeder in das aus einer elastischen Masse gefertigte Element eingebettet sein.In a variant of the invention, the reset element is integrated in the element. For example, a return spring can be embedded in the element made of an elastic mass.

Vorzugsweise ist der Antrieb an einem Ende ortsfest festgelegt. Mit dem anderen Ende steht der Antrieb Ć¼ber ein Verbindungselement mit dem Element in Verbindung. Durch die Kontraktions- und ExpansionsvorgƤnge im Antrieb entsteht dadurch eine Verformungsbewegung des Elements, welche zu einer Durchmischung des Mediums fĆ¼hrt.The drive is preferably fixed at one end. At the other end, the drive is connected to the element via a connecting element. The contraction and expansion processes in the drive result in a deformation movement of the element, which leads to a mixing of the medium.

Als besonders gĆ¼nstig erweist es sich, wenn der Antrieb in einem Raum angeordnet ist, der abgeschlossen ist gegenĆ¼ber dem zu durchmischenden Medium.It proves to be particularly favorable if the drive is arranged in a space which is sealed off from the medium to be mixed.

Der Raum weist einen Einlass auf, durch den die Edukte fĆ¼r die Oxidation dem Katalysatormaterial zustrƶmen. An dem Material findet eine katalytische Oxidation statt. Dabei kann es sich um eine Totaloxidation mit den Produkten Wasser bzw. Kohlendioxid handeln oder um eine Partialoxidation, bei der auch Kohlenmonoxid oder organische Produkte entstehen kƶnnen.The room has an inlet through which the starting materials for the oxidation flow to the catalyst material. Catalytic oxidation takes place on the material. This can be a total oxidation with the products water or carbon dioxide or a partial oxidation in which carbon monoxide or organic products can also be formed.

Ein Stoffstrom mit den entstandenen Produkten und den nicht umgesetzten Edukten verlƤsst den Raum durch einen Auslass.A material flow with the resulting products and the unreacted starting materials leaves the room through an outlet.

Weitere Merkmale und Vorteile der Erfindung ergeben durch Beschreibung eines AusfĆ¼hrungsbeispieles anhand einer Zeichnung und aus der Zeichnung selbst.Further features and advantages of the invention result from the description of an exemplary embodiment with reference to a drawing and from the drawing itself.

In the exemplary embodiment, the connecting element 3 is a wire which is embedded in the element 1 and is connected to the drive by means of deflection rollers 4.

Der Antrieb umfasst ein erstes Material 5, das als innerer Kern in Form eines Zylinders ausgebildet ist und ein zweites Material 6 als ƤuƟere HĆ¼lle, die ringfƶrmig das erste Material 5 umgibt.The drive comprises a first material 5, which is designed as an inner core in the form of a cylinder, and a second material 6 as an outer shell, which surrounds the first material 5 in a ring.

Bei dem stabartigen Kern des Antriebs 2 handelt es sich um ein Material 5 zur DurchfĆ¼hrung einer thermischen Ƅnderung der geometrischen Abmessungen. Im AusfĆ¼hrungsbeispiel kommt dabei ein FormgedƤchtnismaterial zum Einsatz, das als Nickel-Titan-Legierung ausgefĆ¼hrt ist.The rod-like core of the drive 2 is a material 5 for carrying out a thermal change in the geometric dimensions. In the exemplary embodiment, a shape memory material is used which is designed as a nickel-titanium alloy.

Die ringfƶrmige ƤuƟere HĆ¼lle des Antriebs 2 besteht aus einem Material 6, das als Katalysator fĆ¼r eine Oxidationsreaktion dient. Im AusfĆ¼hrungsbeispiel kommt dabei ein platinhaltiges Material zum Einsatz. Es handelt sich um Kohlenstoffnanorƶhrchen, die mit Platinpartikeln beschichtet sind.The annular outer shell of the drive 2 consists of a material 6 which serves as a catalyst for an oxidation reaction. In the exemplary embodiment, a platinum-containing material is used. They are carbon nanotubes coated with platinum particles.

Durch einen Einlass 7 strƶmt gemƤƟ dem oberen Blockpfeil ein Gemisch in einen Raum 8, das ein Oxidationsmittel und einen zu oxidierenden Stoff aufweist. Im AusfĆ¼hrungsbeispiel handelt es sich bei dem Oxidationsmittel um Sauerstoff oder Luft und bei dem zu oxidierenden Stoff um Wasserstoff.According to the upper block arrow, a mixture flows through an inlet 7 into a space 8 which has an oxidizing agent and a substance to be oxidized. In the exemplary embodiment, the oxidizing agent is oxygen or air and the substance to be oxidized is hydrogen.

Der Raum 8 ist von einem GehƤuse 9 von dem Raum 10 getrennt, in dem sich das zu durchmischende Medium befindet.The space 8 is separated from the space 10 by a housing 9 in which the medium to be mixed is located.

Der oxidierende Stoff wird mit dem Oxidationsmittel am katalytischen Material 6 umgesetzt. Im AusfĆ¼hrungsbeispiel reagiert dabei Wasserstoff und Sauerstoff zu Wasser. Das Gemisch mit den Reaktionsprodukten und den nicht umgesetzten Edukten verlƤsst den Raum 8 durch einen Auslass in Richtung des unteren Blockpfeils.The oxidizing substance is reacted with the oxidizing agent on the catalytic material 6. In the exemplary embodiment, hydrogen and oxygen react to form water. The mixture with the reaction products and the unreacted starting materials leaves space 8 through an outlet in the direction of the lower block arrow.

Bei der exothermen Reaktion wird WƤrme frei, die an den inneren Kern des Antriebszweigs Ć¼bertragen wird. Das Material 5 erwƤrmt sich und Ƥndert seine geometrischen Abmessungen. Beispielsweise kann es zu einer LƤngenkontraktion kommen, sodass sich der stabartige Antrieb 2 zusammenzieht.The exothermic reaction releases heat that is transferred to the inner core of the drive branch. The material 5 heats up and changes its geometric dimensions. For example, there may be a contraction in length so that the rod-like drive 2 contracts.

Dadurch wird das drahtartige Verbindungselement 3 gespannt, sodass die Flanken des glockenartigen Elements 1 nach oben verformt werden. Die Stellung ist in Figur 1 dargestellt.As a result, the wire-like connecting element 3 is tensioned, so that the flanks of the bell-like element 1 are deformed upward. The position is in Figure 1 shown.

Bei der Verformung des Elements 1 wird Medium in Bewegung versetzt und es findet eine Durchmischung statt.When the element 1 is deformed, the medium is set in motion and mixed.

In einer zweiten Phase endet die Oxidationsreaktion am Material 6. Die Reaktion kommt beispielsweise zum Stillstand, weil kein neues oxidierendes Mittel mehr zugefĆ¼hrt wird bzw. im Raum 8 bereits verbraucht wurde. Ohne die exotherme Reaktion kĆ¼hlt sich der stabartige Antrieb 2 ab. Beispielsweise fĆ¼hrt dies zu einer LƤngenƤnderung, wodurch das drahtartige Verbindungselement 3 seine mechanische Spannung verliert und die Flanken bzw. FlĆ¼gel des glockenfƶrmigen Elements 1 wieder nach unten klappen in Figur 2 dargestellte Ausgangsposition. Dabei zu ergƤnzend oder alternativ ein RĆ¼ckstellelement 10 eine RĆ¼ckverformung bewirken.The oxidation reaction on material 6 ends in a second phase. The reaction comes to a standstill, for example, because no new oxidizing agent is added or has already been consumed in room 8. Without the exothermic reaction, the rod-like drive 2 cools down. For example, this leads to a change in length, as a result of which the wire-like connecting element 3 loses its mechanical tension and the flanks or wings of the bell-shaped element 1 fold down again Figure 2 shown starting position. In addition or alternatively, a restoring element 10 brings about a reshaping.

Die zuvor beschriebenen Phasen wiederholen sich zyklisch.The phases described above are repeated cyclically.
