Abstract

Materials at the bottom of the container enter the homogenizing unit and fall upon a rotor (4) driven by a shaft (30), and are dispersed by two sets of vanes. A pump rotor (6) is driven through a hollow shaft (36), coaxial with the first shaft. Vanes on the rotor force the homogenized material into a circumferential channel (20) from where it is either recirculated to the container or sent to storage. Materials at the bottom of the container enter the homogenizing unit along the vertical centerline to fall upon a rotor (4) driven by a shaft (30). They are then dispersed by two sets of vanes running between two sets of rings that form part of the fixed base (2). A pump rotor (6) is driven through a hollow shaft (36), coaxial with the first shaft. Vanes on the rotor force the homogenized material into a circumferential channel (20) from where it is either recirculated to the container or sent to storage. The shafts (30,36) are driven independently so that the rotors can in the same or in opposite directions.

Description

Die Erfindung betrifft einen Homogenisator zum Homogenisieren fließfähiger Stoffe, mit einem in einem Gehäuse drehbar gelagerten und mittels einer Antriebseinrichtung antreibbaren Rotor.The invention relates to a homogenizer for homogenizing flowable substances, with a rotatably mounted in a housing and by means of a drive device drivable rotor.

Derartige Homogenisatoren werden beispielsweise in der kosmetischen, pharmazeutischen oder chemischen Industrie bei der Herstellung von Cremes, Salben, Pasten oder dgl. eingesetzt. Der Homogenisator ist z. B. am tiefsten Punkt eines Behälters angeordnet und homogenisiert und/oder dispergiert den fließfähigen Stoff, indem der Rotor zusammen mit einem ortsfesten Stator Scherkräfte auf den Stoff aufbringt. Der Homogenisator könnte auch separat neben einem oder zwischen zwei Behälter(n) plaziert sein. Der homogenisierte Stoff kann entweder zurück in den Behälter oder zu einer Abfüllanlage gefördert werden.Such homogenizers are used, for example, in cosmetic, pharmaceutical or chemical industry in the manufacture of creams, ointments, pastes or the like. Used. The homogenizer is e.g. B. at the lowest point of a container arranged and homogenized and / or dispersed the flowable material by the rotor together with a stationary stator shear forces on the fabric applies. The homogenizer could also be placed separately next to one or between two Container (s) must be placed. The homogenized substance can either be returned to the Containers or be promoted to a bottling plant.

Die Homogenisierung läßt sich bei bekannten Homogenisatoren im wesentlichen durch Variation der Drehzahl des Rotors gegenüber dem festem Stator oder durch die konkrete Gestaltung des Rotors und/oder des Stators beeinflussen. Bei hohen Drehzahlen ist die Scherwirkung und auch die Förderwirkung des Homogenisators größer als bei niedrigen Drehzahlen. Ein Nachteil der bekannten Homogenisatoren besteht darin, dass die Scherwirkung und die Förderwirkung unmittelbar miteinander gekoppelt sind. Darüber hinaus ist es für die Erreichung hoher Scherwirkungen und Drehzahlen des Rotors notwendig, die Antriebseinrichtungen und Antriebsmotoren entsprechend aufwendig auszulegen. Homogenization can be carried out essentially with known homogenizers by varying the speed of the rotor compared to the fixed stator or by influence the specific design of the rotor and / or the stator. At high Speed is the shear effect and also the conveying effect of the homogenizer larger than at low speeds. A disadvantage of the known homogenizers is that the shear effect and the promotional effect are directly related are coupled. In addition, it is for achieving high shear and Speeds of the rotor necessary, the drive devices and drive motors to interpret accordingly complex.

Ein weiterer Nachteil besteht darin, dass bei zu hoher Drehzahl des Motors die Scherwirkung so groß wird, dass der zu homogenisierende Stoff nachteilig beeinflusst oder eventuell sogar beschädigt werden kann.Another disadvantage is that if the engine speed is too high, the The shear effect becomes so great that the substance to be homogenized is disadvantageous influenced or possibly even damaged.

Um dem Erfordernis der hohen Pumpleistung (Förderwirkung) gerecht werden zu können und gleichzeitig die Scherwirkung bei hohen Drehzahlen reduzieren zu können, wurden Homogenisatoren entwickelt, die eine axiale Verschiebung des Rotors relativ zum Stator ermöglichen, um die freien Strömungsquerschnitte (oder Spalte) zwischen den Flügeln des Rotors und des Stators zu erhöhen (vgl. DE 296 08 712 oder DE 24 13 452). Der konstruktive Aufwand für eine derartige axiale Verschiebbarkeit ist sehr hoch.To meet the requirement of high pumping capacity (pumping effect) can and at the same time reduce the shear effect at high speeds can, homogenizers have been developed that an axial displacement of the Rotors relative to the stator allow the free flow cross sections (or Column) between the blades of the rotor and the stator (see DE 296 08 712 or DE 24 13 452). The design effort for such an axial Movability is very high.

Aufgabe der vorliegenden Erfindung ist es, einen Homogenisator bereitzustellen, mit dem auf konstruktiv einfache Weise der Homogenisierungseffekt beeinflußbar ist und die Scherwirkung und die Pumpwirkung an die jeweiligen Erfordernisse anpassbar sind.The object of the present invention is to provide a homogenizer with which the homogenization effect can be influenced in a structurally simple manner and the shear effect and the pump effect to the respective requirements are customizable.

Die Erfindung löst diese Aufgabe beim Homogenisator der eingangs genannten Art durch ein drehbar in dem Gehäuse gelagertes und mittels einer Antriebseinrichtung unabhängig von dem Rotor antreibbares Element zum Homogenisieren und/oder Fördern des fließfähigen Stoffes.The invention solves this problem with the homogenizer of the type mentioned by a rotatably mounted in the housing and by means of a drive device Independently driven element for homogenization and / or Conveying the flowable material.

Die Vorteile der Erfindung bestehen im wesentlichen darin, dass durch das zusätzliche, separat und unabhängig vom Rotor antreibbare Element die Homogenisierung und Förderung auf vielfältige Weise beeinflusst und an die jeweiligen Produktionserfordernisse angepasst werden kann. Insbesondere durch Einstellung und Variation der Relativgeschwindigkeit des drehbaren Elements relativ zum Rotor lässt sich die Scherwirkung des Rotors und des drehbaren Elements auf dem Stoff einstellen. Das drehbare Element kann gleichsinnig oder gegenläufig zum Rotor angetrieben werden, um die Scherwirkung stufenlos innerhalb großer Bereiche variieren zu können. Darüber hinaus kann die Scherwirkung unabhängig von der Förderleistung (d. h. der Fördermenge des Stoffs) variiert werden. Beispielsweise kann die Pumpleistung konstant auf einem drehzahlabhängigen Wert gehalten werden, während die Scherwirkung bei Drehung des drehbaren Elements mit derselben oder annäherend derselben Drehgeschwindigkeit in der selben Drehrichtung gegen Null geht. Bei maximalen entgegengesetzen Drehgeschwindigkeiten ist die Scherwirkung maximal, wobei für dieselbe Scherwirkung eine wesentlich geringere absolute Drehgeschwindigkeit notwendig ist im Vergleich zu herkömmlichen Homogenisatoren. Dem gemäß können die Antriebe des erfindungsgemäßen Homogenisators für geringere Drehgeschwindigkeiten ausgelegt werden.The advantages of the invention consist essentially in that additional element which can be driven separately and independently of the rotor, the homogenization and funding influenced in many ways and to the respective Production requirements can be adjusted. Especially by hiring and varying the relative speed of the rotatable member relative to the rotor the shear effect of the rotor and the rotatable element on the fabric to adjust. The rotatable element can be in the same direction or counter to the rotor are driven to steer the shear continuously within large areas to be able to vary. In addition, the shear effect can be independent of the Delivery rate (i.e. the delivery rate of the substance) can be varied. For example the pump output can be kept constant at a speed-dependent value be while the shear action with rotation of the rotatable element the same or approximately the same speed of rotation in the same direction of rotation goes to zero. At maximum opposite rotation speeds the maximum shear effect, one essential for the same shear effect lower absolute speed of rotation is necessary compared to conventional Homogenizers. Accordingly, the drives of the invention Homogenizer can be designed for lower speeds.

Gemäß einer Variante der Erfindung ist das drehbare Element als Pumprad mit mehreren Pumpschaufeln ausgebildet, um hohe Pumpleistungen erzielen zu können, während der Rotor im wesentlichen die Scherwirkung des Homogenisators erzeugt.According to a variant of the invention, the rotatable element is a pump wheel several pump blades to be able to achieve high pumping capacities, while the rotor essentially produces the shear effect of the homogenizer.

Bei einer alternativen Ausführungsform wird vorgeschlagen, dass das drehbare Element nach Art eines Stators oder eines Rotors mit Flügeln ausgebildet ist. Hierbei handelt es sich prinzipiell um einen Homogenisator mit einem "drehbaren Stator", um die zuvor beschriebene maximale Scherwirkung erzeugen zu können.In an alternative embodiment it is proposed that the rotatable Element is designed in the manner of a stator or a rotor with wings. Here is basically a homogenizer with a "rotating stator", in order to be able to produce the maximum shear effect described above.

Gemäß einer besonders bevorzugten Ausführungsform ist vorgesehen, dass das drehbare Element und der Rotor mit zwei koaxial zueinander angeordneten Antriebswellen zum Antreiben des drehbaren Elements bzw. des Rotors gekoppelt sind. Diese konstruktiv einfache Lösung ist platzsparend. Zur Reduzierung des Gewichts und der Materialkosten ist eine der beiden Antriebswellen vorzugsweise als Hohlwelle ausgebildet.According to a particularly preferred embodiment, it is provided that rotatable element and the rotor with two coaxially arranged to each other Drive shafts coupled to drive the rotatable element or the rotor are. This structurally simple solution is space-saving. To reduce the Weight and material costs is one of the two drive shafts preferred designed as a hollow shaft.

Die Lagerung der Antriebswellen ist auf zweckmäßige Weise so gestaltet, dass die innere Antriebswelle mittels Wälzlagern in der äußeren Welle gelagert ist und die äußere Welle ihrerseits in einem Gehäuse gelagert ist.The storage of the drive shafts is expediently designed so that the inner drive shaft is mounted in the outer shaft by means of roller bearings and outer shaft is in turn mounted in a housing.

Um den Innenraum des Homogenisators gegenüber der Umgebung zuverlässig auch gegenüber hohen Druckdifferenzen und ggf. agressiven Medien abzudichten, wird gemäß einer Weiterbildung vorgeschlagen, dass mindestens eine Gleitringdichtung zur Abdichtung des Innenraums des Gehäuses des Homogenisators gegenüber der Umgebung vorgesehen ist. In den Innenräumen eines Rührwerkbehälters, an den ein erfindungsgemäßer Homogenisator anschliessbar ist, herrschen häufig Unter- oder Überdrücke, die so sicher beherrscht werden.To the interior of the homogenizer in relation to the environment reliably too to seal against high pressure differences and possibly aggressive media According to a further development proposed that at least one mechanical seal to seal the interior of the housing of the homogenizer against the Environment is provided. In the interior of an agitator tank to which a homogenizer according to the invention can be connected, there are often or overpressures that can be safely controlled.

Eine konstruktiv einfache Gestaltung des Rotors und des drehbaren Elements sieht vor, dass der Rotor und/oder das drehbare Element eine mit der zugehörigen Antriebswelle gekoppelte Grundplatte aufweist, von der die Flügel axial abstehen, dass die Drehachsen der Antriebswellen im Betrieb im wesentlichen vertikal angeordnet ist und dass die Wellen mittels jeweils eines Zahnriemens angetrieben werden. Anstelle eines Zahnriemens könnten Ketten, Keilriemen, Reibräder, Zahnräder o. dgl. verwendet werden. A structurally simple design of the rotor and the rotatable element sees before that the rotor and / or the rotatable member one with the associated one Drive shaft coupled base plate from which the wings project axially, that the axes of rotation of the drive shafts in operation are essentially vertical is arranged and that the shafts are driven by means of a toothed belt become. Instead of a toothed belt, chains, V-belts, friction wheels, Gears or the like can be used.

Die Scherwirkung und die Pumpwirkung kann auf einfache Weise dadurch variiert werden, dass die Antriebsmotoren des Rotors und des drehbaren Elements so steuerbar sind, dass Rotor und drehbares Element mit einstellbaren Relativgeschwindigkeiten gleichsinnig oder gegenläufig drehbar sind oder wahlweise entweder der Rotor oder das drehbare Element angetrieben werden, während das jeweils andere Bauteil still steht.The shearing action and the pumping action can thereby be varied in a simple manner that the drive motors of the rotor and the rotatable element so are controllable that rotor and rotatable element with adjustable relative speeds are rotatable in the same direction or in opposite directions or alternatively either the rotor or the rotatable member are driven while the each other component stands still.

Eine weitere bevorzugte Ausführungsform sieht vor, dass das Gehäuse des Homogenisators eine Einlassöffnung, durch die fliessfähiges Material aus einem Behälter axial in den Innenraum einströmen kann, und eine Ausgangsöffnung aufweist, durch die der homogenisierte fließfähige Stoff im wesentlichen radial und/oder tangential aus dem Gehäuse ausströmt, und dass zwei mit der Ausgangsöffnung des Gehäuses kommunizierende Rückführungsleitungen vorgesehen sind, durch die in Abhängigkeit von der Stellung eines Stellventils der fließfähige Stoff an unterschiedliche Orten in den Behälter rückführbar ist. Auf diese Weise kann der Stoff beispielsweise oben in den Behälter oder nahe dem Homogenisator wieder rückgeführt werden, was für geringe Mengen eines zu homogenisierenden Stoffs zweckmäßig ist.Another preferred embodiment provides that the housing of the Homogenizer an inlet opening through which flowable material from a Container can flow axially into the interior, and an outlet opening through which the homogenized flowable substance is essentially radial and / or flows tangentially out of the housing, and that two with the exit opening return lines communicating with the housing are provided, due to the flowable substance depending on the position of a control valve different places in the container is traceable. In this way, the For example, material in the top of the container or near the homogenizer again be recycled, what small amounts of a substance to be homogenized is appropriate.

Die Scherwirkung lässt sich dadurch weiter optimieren, dass zusätzliche, ortsfeste Stator-Verzahnungen an einem Gehäuses des Homogenisators angeordnet sind.The shear effect can be further optimized by the fact that additional, stationary Stator teeth are arranged on a housing of the homogenizer.
