Description

Die Erfindung betrifft einen Homogenisator mit einem in eine Homogenisationskammer führenden Zufluss, einem aus der Homogenisationskammer führenden Abfluss, einem Stator und einem zusammen mit dem Stator Scherkräfte bewirkenden Rotorkopf, wobei Stator und Rotorkopf in der Homogenisationskammer angeordnet sind, einer mit dem Rotorkopf verbundenen Rotorwelle, einem auf einem Rotorlagerträger angeordneten, die Rotorwelle lagernden Rotorlager, und einem die Rotorwelle antreibenden Motor.The invention relates to a homogenizer with an inlet leading into a homogenization chamber, a discharge leading out of the homogenization chamber, a stator and a rotor head effecting shear forces together with the stator, the stator and rotor head being arranged in the homogenization chamber, a rotor shaft connected to the rotor head arranged on a rotor bearing carrier, the rotor shaft bearing rotor bearing, and a rotor driving the motor shaft.

Insbesondere betrifft die Erfindung einen Homogenisator zum Homogenisieren von Schiffdiesel und Schweröl, sowie zum Erzeugen von Kraftstoff/Wasser- und Kraftctoff/Kraftstoff-Emulsionen.In particular, the invention relates to a homogenizer for homogenizing marine diesel and heavy oil, as well as for producing fuel / water and Kraftctoff / fuel emulsions.

Homogenisatoren zur Vermeidung von Ölsehlammrückständen, zur Verbesserung der Verbrennung von Kraftstoffen oder zur Reduzierung der Stickoxidemission durch Erzeugen und Verwenden von Kraftstoff/Wasser- bzw. Wasser/Kraftstoff-Emulsionen sind allgemein bekanntHomogenizers to avoid residual oil sludge, to improve the combustion of fuels or to reduce nitrogen oxide emissions by generating and using fuel / water or water / fuel emulsions are well known

Da es sich bei den verwendeten Kraftstoffen um bei Raumtemperatur hoch viskose Flüssigkeiten handelt, ist es notwendig die zu homogenisierenden Flüssigkeiten zu erwärmen, um einen geeignet fließfähigen Kraftstoff oder eine geeignet fließfähige Kraftstoffemulsion zu erhalten. Da eine vor dem Zuführen in den Homogenisator erwärmte Flüssigkeit beim Passieren durch einen nicht temperierten Homogenisator an Temperatur verlieren und im Homogenisator eine höhere Viskosität ausbilden und den Homogenisator entsprechend höher viskos verlassen würde, weisen die bekannten Homogenisatoren regelmäßig Heizeinrichtungen zur Temperierung der Homogenisatoren auf, damit weder der Homogenisator noch die Verbrennungskraftmaschine durch Flüssigkeiten mit zu hoher Viskosität geschädigt werden.Since the fuels used are liquids which are highly viscous at room temperature, it is necessary to heat the liquids to be homogenized in order to obtain a suitable flowable fuel or a suitable flowable fuel emulsion. Since a liquid heated before being fed into the homogenizer loses temperature as it passes through a non-tempered homogenizer and forms a higher viscosity in the homogenizer and accordingly leaves the homogenizer more viscous, the known homogenizers regularly have heaters for tempering the homogenizers, so that neither the homogenizer nor the internal combustion engine are damaged by liquids with too high viscosity.

Zu anderen Zwecken verwendete beheizbare Homogenisatoren sind beispielsweise aus der US 3 333 828 A , die einen Homogenisator gemäß dem Oberbegriff des Anspruchs 1 offenbart, und der FR 1 194 715 A bekannt.Heatable homogenizers used for other purposes are known, for example, from US Pat US 3 333 828 A , which discloses a homogenizer according to the preamble of claim 1, and the FR 1 194 715 A known.

Beispielsweise sind Homogenisatoren bekannt, bei denen im Gehäuse des Homogenisators eine Temperiereinrichtung zur Temperierung der den Homogenisator durchlaufenden Flüssigkeiten in Form von die Homogenisationskammer spiralig umlaufenden Leitungen vorgesehen sind, die ein von Außen zugeführtes als Wärmeträger geeignetes Medium aufnehmen, z.B. Wasserdampf oder ein Thermalöl. Dabei können die Leitungen auch zusätzlich mit elektrischen Heizdrähten umwickelt sein.For example, homogenizers are known in which in the housing of the homogenizer, a temperature control for controlling the temperature of the homogenizer passing through liquids in the form of the homogenization chamber spirally circulating lines are provided which receive an externally supplied as a heat transfer medium suitable, e.g. Steam or a thermal oil. The cables can also be wrapped in addition with electrical heating wires.

Nachteilig an dieser Ausgestaltung ist jedoch, dass die den Homogenisator durchlaufenden Flüssigkeiten nur von Außen temperiert werden können, sodass es - insbesondere wegen der in den Homogenisatoren konstruktionsbedingten (isolierenden) Lufträume - nur zu einem ungenügenden Wärmeübergang zu weiter innen im Homogenisator liegenden flüssigkeitsgefüllten Räumen, einer damit einhergehenden unzureichenden Temperierung dieser Flüssigkeit und folglich einer von der für den Betrieb des Homogenisators geforderten Viskosität abweichenden Viskosität kommen kann, wodurch unmittelbar die Gefahr einer Beschädigung des Homogenisators, insbesondere des Rotorlagers, besteht.A disadvantage of this configuration, however, is that the liquids passing through the homogenizer can be tempered only from the outside, so that it - only because of insufficient in the heat transfer to the interior lying in the homogenizer liquid-filled rooms - especially because of the homogenizing in the homogenizers (insulating) air spaces concomitant inadequate temperature control of this liquid and, consequently, a viscosity deviating from the viscosity required for the operation of the homogenizer, whereby there is a direct risk of damaging the homogenizer, in particular the rotor bearing.

Aufgabe der Erfindung ist es daher einen Homogenisator zu schaffen, der eine gleichmäßige Temperierung der einen Homogenisator durchlaufenden Flüssigkeiten ermöglicht. Insbesondere soll der grundsätzlich bekannte einfache und kompakte Aufbau des Homogenisators beibehalten und der Arbeitsaufwand zur Verwirklichung der Erfindung so gering wie möglich gehalten werden.The object of the invention is therefore to provide a homogenizer which allows a uniform temperature of a homogenizer passing through liquids. In particular, the basically known simple and compact design of the homogenizer should be maintained and the amount of work required to achieve the invention be kept as low as possible.

Die Aufgabe wird durch den Homogenisator mit den Merkmalen von Anspruch 1 gelöst. Die Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung an.The object is achieved by the homogenizer having the features of claim 1. The subclaims indicate advantageous embodiments of the invention.

Grundgedanke der Erfindung ist es, den Homogenisator nicht von Außen, sondern von Innen zu beheizen, da hierdurch ein wesentlich besserer Wärmeübergang zur in den Homogenisator eingebrachten Flüssigkeit geschaffen wird. Dabei wird die Temperierung von Innen ohne aufwändige Maßnahmen oder zusätzliches Material dadurch einfach ermöglicht, dass der Rotorlagerträger des Homogenisators einen Hohlraum aufweist, der zur Aufnahme eines geeigneten Wärmeträgers eingerichtet ist.The basic idea of the invention is not to heat the homogenizer from the outside, but from the inside, since this provides a significantly better heat transfer to the liquid introduced into the homogenizer. In this case, the temperature control of the inside without complicated measures or additional material is thereby made possible simply by the fact that the rotor bearing carrier of the homogenizer has a cavity which is set up for receiving a suitable heat carrier.

Die Erfindung wird anhand eines in den Zeichnungen dargestellten, besonders bevorzugt ausgestalteten Ausführungsbeispiels näher erläutert. Es zeigen:

The invention will be explained in more detail with reference to an embodiment shown in the drawings, particularly preferred embodiment. Show it:

Fig. 1 zeigt einen äußerlich nicht von einem herkömmlichen Homogenisator zu unterscheidenden Homogenisator nach der Erfindung. Der Homogenisator 10 weist einen dem Homogenisator 10 Flüssigkeit zuführenden Zufluss 20 und eine nach Durchlaufen der (nicht näher bezeichneten) Homogenisationskammer die homogenisierte Flüssigkeit abführenden Abfluss 30 auf. Dabei ist zu erkennen, dass der erfindungsgemäße Homogenisator 10 einen dreiteiligen Aufbau (I, II, III) aufweist. Dem Zufluss 20 gegenüber ist der Motor 80 (III) angeordnet, der über einen Flansch mit dem eigentlichen Funktionsbereich des Homogenisators 10 verbunden ist. Dieser ist wiederum aus zwei über einen Flansch verbundene Gehäusebauteile I, II gebildet. Fig. 1 shows a homogenizer not to be distinguished externally from a conventional homogenizer according to the invention. The homogenizer 10 has an inlet 20 supplying the liquid to the homogenizer 10 and a drain 30 discharging the homogenized liquid after passing through the homogenization chamber (not designated in greater detail). It can be seen that the homogenizer 10 according to the invention has a three-part structure (I, II, III). The inflow 20 opposite the motor 80 (III) is arranged, which is connected via a flange with the actual functional area of the homogenizer 10. This in turn is formed from two housing components I, II connected via a flange.

Wie Fig. 2 zu entnehmen ist, nimmt das erste, den Zufluss 20 aufweisende Gehäusebauteil I die Homogenisationskammer auf. In dieser ist der Stator 40 und der Rotorkopf 50 angeordnet, die über ein voreingestelltes, bevorzugt veränderbares Spaltmaß bei Rotation des Rotorkopfes 50 auf die in die Homogenisationskammer eingeführte Flüssigkeit Scherkräfte ausüben und so eine Homogenisierung der dem Homogenisator 10 zugeführten Flüssigkeit bewirken.As Fig. 2 can be seen, takes the first, the inflow 20 having housing component I on the homogenization chamber. In this, the stator 40 and the rotor head 50 is arranged, which exert shear forces by means of a preset, preferably variable gap dimension upon rotation of the rotor head 50 onto the liquid introduced into the homogenization chamber and thus bring about homogenization of the liquid supplied to the homogenizer 10.

Wie aus dem Stand der Technik bekannt, ist im Gehäuse dieses ersten Abschnitts I bevorzugt eine Temperiereinrichtung 120 vorgesehen, die herkömmlich als schlauchartige am Umfang der Homogenisationskammer spiralartig geführte Leitungen ausgebildet sein kann, die ein als Wärmeträger geeignetes Medium führen und zur Temperierung der Homogenisationskammer beitragen. Wie oben diskutiert, würde diese Einrichtung 120 allein nur unzureichend zu einer Temperierung des flüssigkeitsgefüllten mit F gekennzeichneten innen liegenden Hohlraums führen, wobei eine erhöhte Viskosität in diesem Bereich aufgrund niedriger Temperatur herkömmlich zu den aus dem Stand der Technik bekannten Problemen führt. Die Temperiereinrichtung 120 kann jedoch bevorzugt zusätzlich verwendet werden, um die erfindungsgemäße Ausgestaltung des Homogenisators 10 weiter zu unterstützen.As is known from the prior art, a tempering device 120 is preferably provided in the housing of this first section I, which conventionally has a tubular shape on the circumference the homogenization chamber spirally guided lines can be formed, which lead a suitable medium as a heat transfer medium and contribute to the temperature of the homogenization chamber. As discussed above, this device 120 alone would not adequately control the temperature of the fluid-filled internal cavity marked F, with increased viscosity in this region due to low temperature commonly resulting in problems known in the prior art. However, the tempering device 120 may preferably additionally be used to further support the inventive design of the homogenizer 10.

Der Rotorkopf 50 ist mit der Rotorwelle 60 verbunden, die im gezeigten Beispiel über eine Magnetkupplung von der Antriebswelle 100 des Motors 80 angetrieben wird (vgl. Fig. 3a) Die Rotorwelle 60 ist an einem Rotorlager gelagert, das mit einem Rotorlagerträger 70 verbunden ist. Der Rotorlagerträger 70 ist bevorzugt zwischen die Flansche des ersten und zweiten Gehäusebauteils I, II des Homogenisators 10 eingebracht und an diesen befestigt.The rotor head 50 is connected to the rotor shaft 60, which is driven in the example shown by a magnetic coupling of the drive shaft 100 of the motor 80 (see. Fig. 3a ) The rotor shaft 60 is mounted on a rotor bearing which is connected to a rotor bearing carrier 70. The rotor bearing carrier 70 is preferably introduced between the flanges of the first and second housing component I, II of the homogenizer 10 and attached thereto.

Da - wie oben diskutiert - die im Gehäuse I angeordnete Temperiereinrichtung als nur ungenügend erscheint, ist erfindungsgemäß vorgesehen, dass der Rotorlagerträger 70 einen Hohlraum 90 zur Aufnahme eines die den Homogenisator 10 durchlaufende Flüssigkeit temperierenden Mediums aufweist, der über einen Zulauf 90a und einen Ablauf 90b verfügt. Über den Zulauf 90a wird bei Betrieb des Homogenisators ein geeignet temperiertes Medium als Wärmeträger zugeführt, z.B. ein Thermalöl.Since, as discussed above, the tempering device arranged in the housing I appears to be insufficient, it is provided according to the invention that the rotor bearing carrier 70 has a cavity 90 for receiving a medium which controls the liquid flowing through the homogenizer 10, via an inlet 90a and a drain 90b features. During operation of the homogenizer, a suitably tempered medium is supplied via the inlet 90a as a heat carrier, e.g. a thermal oil.

Bevorzugt sind Zulauf 90a und Ablauf 90b am Flansch des Rotorlagerträgers 70 angeordnet, wobei sich der Rotorlagerträger 70 besonders bevorzugt entlang der Rotorwelle 60 derart erstreckt, dass der Hohlraum 90 als die Rotorwelle 60 wenigstens teilweise umgebender Mantel ausgebildet ist. Dabei können der Zulauf 90a und/oder der Ablauf 90b auch bevorzugt durch Flansche des Homogenisatorgehäuses I, II gebildet sein.Preferably, inlet 90a and outlet 90b are arranged on the flange of the rotor bearing carrier 70, wherein the rotor bearing carrier 70 particularly preferably extends along the rotor shaft 60 such that the cavity 90 is formed as the rotor shaft 60 at least partially surrounding sheath. In this case, the inlet 90a and / or the outlet 90b may also preferably be formed by flanges of the homogenizer housing I, II.

Schließlich ist bevorzugt vorgesehen, dass der Zulauf 90a für den Wärmeträger oberhalb des Ablaufs 90b des als Wärmeträger geeigneten Mediums und/oder der Abfluss 30 der homogenisierten Flüssigkeit oberhalb des Zuflusses 20 der zu homogenisierenden Flüssigkeit angeordnet ist.Finally, it is preferably provided that the feed 90a for the heat transfer medium above the outlet 90b of the medium suitable as a heat transfer medium and / or the outflow 30 of the homogenized liquid is arranged above the inflow 20 of the liquid to be homogenized.

Besonders vorteilhaft wirkt sich die Erfindung bei Homogenisatoren 10 aus, deren Rotorwelle 60 über eine mit dem Motor 80 verbunden Antriebswelle 100 angetrieben wird, wobei die Rotorwelle 60 und die Antriebswelle 100 eine gemeinsame Magnetkupplung ausbilden, da hier konstruktionsbedingt isolierend wirkende Luftzwischenräume vorliegen, die einen Wärmeübergang auf die den Homogenisator 10 durchlaufende Flüssigkeit nach herkömmlicher Bauart erschweren würden.The invention has a particularly advantageous effect on homogenizers 10, the rotor shaft 60 of which is driven via a drive shaft 100 connected to the motor 80, wherein the rotor shaft 60 and the drive shaft 100 form a common magnetic coupling, since here, due to the design, insulating air spaces are present which provide heat transfer would complicate the homogenizer 10 continuous liquid according to conventional design.

Fig. 3 verdeutlicht den Aufbau des erfindungsgemäßen Homogenisators 10 noch einmal in einer teilweise geschnittenen Seitenansicht (a), anhand eines Querschnitts entlang der Linie A-A (b) und anhand eines Querschnitts entlang der Linie B-B (c). Fig. 3 illustrates the structure of the homogenizer 10 according to the invention again in a partially sectioned side view (a), with reference to a cross section along the line AA (b) and with reference to a cross section along the line BB (c).

Vorteile der vorliegenden Erfmdung sind, dass zur Verwirklichung der Erfindung keine zusätzlichen Bauteile notwendig sind, die einer einfachen und kompakten entgegenwirken würden. Der Hohlraum 90 des Lagerträgers 70 ermöglicht die Leitung großer Volumina des wärmeübertragenden Mediums, wobei einerseits das Homogenisat von innen, andererseits - bei Ausbildung einer Magnetkupplung - die zu heizenden Komponenten der Magnetkupplung direkt ohne weitere Einrichtungen temperiert werden können. Insbesondere ist bei letzt genannter Ausbildung auch die Gefahr von Lagerschäden z.B. aufgrund erstarrten Schweröls im Lager beseitigt.Advantages of the present invention are that for the realization of the invention no additional components are necessary, which would counteract a simple and compact. The cavity 90 of the bearing carrier 70 allows the conduction of large volumes of the heat transfer medium, on the one hand the homogenate from the inside, on the other hand - when forming a magnetic coupling - the components to be heated magnetic coupling can be controlled directly without further facilities. In particular, in the latter training also the risk of bearing damage, e.g. eliminated due to solidified heavy oil in the warehouse.
