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 eine Homogenisiereinrichtung zum Homogenisieren fließfähiger Stoffe, mit einem Behälter, insbesondere Rührwerksbehälter und einem Homogenisator 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 container, in particular agitator container and a homogenizer with a rotatably mounted in a housing and driven by a drive means rotor.

Derartige Homogenisiereinrichtungen 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 aufwändig auszulegen. 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.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. Moreover, in order to achieve high shear effects and rotational speeds of the rotor, it is necessary to design the drive devices and drive motors correspondingly complex. Another disadvantage is that at too high speed of the engine the shear effect becomes 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 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.In order to meet the requirement of high pumping efficiency (conveying effect) and at the same time be able to reduce the shear at high speeds, homogenizers have been developed which allow axial displacement of the rotor relative to the stator to control the free flow cross-sections (or gaps) between the vanes of the rotor and of the stator (see DE 296 08 712 or DE 24 13 452). The design effort for such axial displacement is very high.

Es sind ferner Vorrichtungen bekannt (FR-A-606 508, DE 553 055 C, US-A-4,786,183, WO-A-91 07223, DE 42 09 527 A, GB-A-665 981, EP-A-0 335 096), bei denen zwei gleichsinnig oder gegenläufig angetriebene Elemente zum Mahlen, Mischen, Homogenisieren und/oder Fördern verwendet werden. Ein unabhängiges Eintellen der Förderwirkung und der Scherwirkung ist nur durch eine aufwändige Konstruktion, wie etwa Einstellen des Abstandes zwischen den drehbaren Elementen (z, B. FR-A-606 508) oder Deckel- bzw. Ventilanordnungen (z. B. EP-A-0 335 096) möglich. Aufgabe der vorliegenden Erfindung ist es, eine Homogenisiereinrichtung bereitzustellen, mit der auf konstruktiv einfache Weise der Homogenisierungseffekt beeinflußbar ist und die Scherwirkung und die Pumpwirkung an die jeweiligen Erfordernisse anpassbar sind.Devices are also known (FR-A-606 508, DE 553 055 C, US-A-4,786,183, WO-A-91 07223, DE 42 09 527 A, GB-A-665 981, EP-A-0 335) 096) in which two co-rotating or counter-rotating elements are used for grinding, mixing, homogenizing and / or conveying. Independent setting of the conveying action and the shearing action is only possible through a complex construction, such as adjusting the distance between the rotatable elements (eg, FR-A-606 508) or lid arrangements (eg EP-A -0 335 096) possible. The object of the present invention is to provide a homogenizing device 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 bei der Homogenisiereinrichtung der eingangs genannten Art durch die Merkmalskombination gemäß Anspruch 1.The invention solves this problem in the homogenizer of the type mentioned by the feature combination according to claim 1.

Bevorzugte Ausführungsformen sind den Unteransprüchen zu entnehmen. 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 Retativgeschwindigkeit 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 annähernd derselben Drehgeschwindigkeit in der selben Drehrichtung gegen Null geht. Bei maximalen entgegengesetzten 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 erfindungsgemä-βen Homogenisators für geringere Drehgeschwindigkeiten ausgelegt werden.Preferred embodiments are given in the dependent claims. 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 rate of retraction 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 (ie 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 when the rotatable member rotates at the same or approximately the same rotational speed in the same direction of rotation. At maximum opposite rotational speeds, the shearing action is maximum, and for the same shearing action, a substantially lower absolute rotational speed is necessary in comparison to conventional homogenizers. Accordingly, the drives of the invention-βen homogenizer 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. aggressiven 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 wer den, 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 easily varied by who the that the drive motors of the rotor and the rotatable member are controllable so that the rotor and rotatable member with adjustable relative velocities are in the same direction or in opposite directions rotatable or selectively driven either the rotor or the rotatable member while the other component is stationary.

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 derA further preferred embodiment provides that the housing of the homogenizer has an inlet opening, through which flowable material from a container can flow axially into the interior space, and an outlet opening, through which the homogenized flowable material substantially radially and / or tangentially out of the Housing flows out, and that two communicating with the outlet opening of the housing return lines are provided, through which depending on the

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.Position of a control valve, the flowable material is traceable to different locations in the container. In this way, the substance, for example, top recycled into the container or near the homogenizer, which is useful for small amounts of a substance to be homogenized.

Die Scherwirkung lässt sich dadurch weiter optimieren, dass zusätzliche, ortsfeste Stator-Verzahnungen an einem Gehäuses des Homogenisators angeordnet sind.The shearing effect can be further optimized by arranging additional, stationary stator toothings on a housing of the homogenizer.
