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 driven by a drive means 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 the cosmetic, pharmaceutical or chemical industry in the preparation of creams, ointments, pastes or the like. The homogenizer is z. B. arranged at the lowest point of a container and homogenized and / or dispersed the flowable material by the rotor together with a stationary stator shearing forces applied to the fabric. The homogenizer could also be placed separately next to or between two containers. The homogenised substance can either be returned to the container or 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.The homogenization can be influenced in known homogenizers essentially by varying the rotational speed of the rotor relative to the fixed stator or by the specific design of the rotor and / or the stator. At high speeds, the shearing action and the conveying action of the homogenizer is greater than at low speeds. A disadvantage of the known homogenizers is that the shearing action and the conveying action are coupled directly to each other. In addition, it is necessary for the achievement of high shear effects and speeds of the rotor to design the drive devices and drive motors accordingly consuming.

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 at too high a speed of the engine, the shearing action is so great that the substance to be homogenized can be adversely affected 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 entwikelt, 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.In order to meet the requirement of high pumping capacity (conveying effect) and at the same time be able to reduce the shearing action at high speeds, homogenizers have been developed which allow an axial displacement of the rotor relative to the stator in order to control the free flow cross sections (or gaps) between the two To increase the wings of the rotor and the stator (cf. DE 296 08 712 or DE 24 13 452 ). The design effort for such axial displacement is very high.

Weitere Homogenisatoren sind aus den folgenden Druckschriften aus dem Stand der Technik bekannt.Further homogenizers are known from the following documents from the prior art.

FR 606.508 offenbart eine Zentrifugalvorrichtung zum Emulgieren, Mischen oder Pulverisieren von Liquiden, Semi-Liquiden oder trockenen Substanzen, bei dem durch den axialen Abstand zwischen zweier rotierenden Scheiben eine Scherwirkung eingestellt wird. FR 606.508 discloses a centrifugal device for emulsifying, mixing or pulverizing liquids, semi-liquids or dry substances, in which a shearing action is set by the axial distance between two rotating disks.

Die Patentschrift DE 553 055 offenbart eine Schleudermühle mit einer schnell laufenden mit Stiftkränzen besetzten Schleuderscheibe und einer dieser gegenüberstehenden gleichachsig angeordneten, langsam laufenden und mit Mitnehmerkränzen besetzte Mitnehmerscheibe, deren Stift- und Mitnehmerkränze ineinandergreifen und die sich in gleichem oder entgegengesetzten Sinne drehen. Die Druckschrift WO 91/07223 offenbart eine Vorrichtung zum Verarbeiten von Gemischen und Pasten, die nach demselben Prinzip aufgebaut ist.The patent DE 553 055 discloses a spin mill with a high-speed centrifugal disc loaded with pin rings and one of these opposed coaxially arranged, slow-moving and Mitnehmerkränzen occupied driver disc, the pin and Mitnehmerkränze interlock and rotate in the same or opposite sense. The publication WO 91/07223 discloses an apparatus for processing blends and pastes constructed according to the same principle.

US 4,786,183 offenbart eine Mischvorrichtung mit einer Vielzahl von Pumpenflügelrädern, die entlang einer gemeinsamen Achse angeordnet sind, wobei die unmittelbar benachbarten Pumpenflügelräder sich in entgegengesetzter Richtung drehen. US 4,786,183 discloses a mixing device having a plurality of pump impellers arranged along a common axis with the immediately adjacent impeller impellers rotating in opposite directions.

Die Offenlegungsschrift DE 42 09 527 A1 offenbart eine Homogenisiermaschine bei der in einem Gehäuse zwei Rotoren gegeneinander laufen, wobei der eine Rotor eine kegelstumpfförmige Oberfläche aufweist und der zweite Rotor mit seiner Oberfläche dem ersten Rotor spaltbildend angepasst ist und beide Oberflächen der Rotoren mit Scherkräfte erzeugenden Einrichtungen versehen sind.The publication DE 42 09 527 A1 discloses a homogenizing machine in which two rotors run in a housing against each other, wherein the one rotor has a frusto-conical surface and the second rotor with its surface is formed gap-forming the first rotor and both surfaces of the rotors are provided with shear forces generating means.

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 shearing action and the pumping action can be adapted to the respective requirements.

Die Erfindung löst diese Aufgabe durch einen Homogenisator mit den Merkmalen des Anspruchs 1 sowie einem Verfahren gemäß Anspruch 11.The invention solves this problem by a homogenizer with the features of claim 1 and a method according to claim 11.

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 the fact that can be influenced by the additional, separately and independently driven by the rotor element homogenization and promotion in a variety of ways and adapted to the respective production requirements. In particular, by adjusting and varying the relative speed of the rotatable member relative to the rotor, the shearing action of the rotor and the rotatable member on the fabric can be adjusted. The rotatable element can be driven in the same direction or in opposite directions to the rotor in order to be able to vary the shearing action steplessly within large areas. In addition, the shearing action can be varied independently of the delivery rate (i.e., the delivery rate of the substance). For example, the pumping power can be kept constant at a speed-dependent value, while the shearing action approaches zero at the same or approximately the same rotational speed in the same direction of rotation when the rotatable element rotates. At maximum opposing rotational speeds, the shearing action is maximal, and for the same shearing action, a substantially lower absolute rotational speed is necessary in comparison to conventional homogenizers. Accordingly, the drives of the homogenizer according to the invention can be designed for lower rotational 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 designed as a pumping wheel with a plurality of pumping blades, in order to be able to achieve high pumping powers, while the rotor essentially produces the shearing action 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 vanes. This is basically a homogenizer with a "rotatable stator" in order to produce the maximum shear 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 the rotatable element and the rotor are coupled to two coaxial drive shafts for driving the rotatable element or the rotor. This simple design solution saves space. To reduce the weight and the material costs, one of the two drive shafts is preferably 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 by means of rolling bearings in the outer shaft and the 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.In order to seal the interior of the homogenizer relative to the environment reliably against high pressure differences and possibly aggressive media, it is proposed according to a development that at least one mechanical seal is provided for sealing the interior of the housing of the homogenizer from the environment. In the interiors of an agitator container, to which a homogenizer according to the invention can be connected, there are often underpressures or overpressures which are controlled so reliably.

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 provides that the rotor and / or the rotatable element has a base plate coupled to the associated drive shaft, from which the wings protrude axially, that the axes of rotation of the drive shafts in operation is arranged substantially vertically and that the shafts are driven by means of a toothed belt. Instead of a toothed belt chains, V-belts, friction wheels, gears o. The like. 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 be varied easily by controlling the drive motors of the rotor and of the rotatable element such that the rotor and the rotatable element have adjustable relative speeds can be rotated in the same direction or in opposite directions or selectively either the rotor or the rotatable element are driven while the other component is stationary.

Die Erfindung 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. Eine weitere bevorzugte Ausführungsform sieht vor, 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.

Also, the rotor 4 or the rotatable member 6 can be stopped while the other component is rotating. The gear 48, 50 and the electric motors 52, 54 can be arranged offset or rotated about longitudinal axes 56, 58.

Die äußere Antriebswelle 36 ist mittels zweier Lager 60, 62, bei denen es sich um Wälz- oder Gleitlager handelt, in einem Gehäuse 64 gelagert, welches an das Gehäuse 2 des Homogenisators angeflanscht ist. Die Grundplatte 32 des drehbaren Elements 6 mit seinen Pumpschaufeln 34 ist mit einem oberen Endabschnitt der Antriebswelle 36 mit Hilfe von Schrauben 66 drehstarr verbunden; selbstverständlich könnten anstelle der Schrauben andere Befestigungsmittel oder eine einstückige Bauweise eingesetzt werden. Im unteren Bereich ist das Gehäuse 64 mit einem Deckel 68 verschlossen, der gleichzeitig das Lager 62 festlegt.The outer drive shaft 36 is supported by means of two bearings 60, 62, which are rolling or plain bearings, in a housing 64, which is flanged to the housing 2 of the homogenizer. The base plate 32 of the rotatable member 6 with its pump blades 34 is rotationally connected to an upper end portion of the drive shaft 36 by means of screws 66; Of course, instead of the screws other fasteners or a one-piece design could be used.

Der Rotor 4 wird mittels der Antriebswelle 30, Zahnriemen 44 und Getriebe 48 und Antriebsmotor 52 angetrieben. Das drehbare Element 2 wird mittels der äußeren Antriebswelle 36, Zahnriemen 46, Getriebe 50 und Antriebsmotor 54 unabhängig von dem Rotor 4 angetrieben. Das rotierbare Element 2 ist mit äußeren, an der Grundplatte 32 befestigten Pumpschaufeln 34 versehen, die in eine radial einwärts gerichtete obere Ringscheibe 82 übergehen, von welcher axial in Richtung auf die Grundplatte 24 abstehende nach Art eines Stators ausgebildete Flügel- oder Statorelemente 84 angeformt sind, die zwischen den Pumpflügeln 34 und den Flügeln 28 bzw. zwischen den Flügeln 26 und 28 angeordnet sind und die Scherwirkung erhöhen. Die Statorelemente 84 sind zusammen mit dem drehbaren Element 2 und den Pumpschaufeln 34 rotierbar. Da die Schaufeln 84 nach Art eines herkömmlichen Stators ausgebildet und diese rotierbar sind, kann auch von einem "dynamischen Stator" gesprochen werden.This in FIG. 4 partially illustrated embodiment of a homogenizer according to the invention is designed in principle similar to the embodiment described above, so that in order to avoid repetition to the above descriptions, reference is made in full and only differences will be described below.
