Description

Begasungsvorrichtung für Flüssigkeiten Um eine Flüssigkeit mit einem gasförmigen Medium zu vermischen, hat man bereits Vorrichtungen verwendet, die in einem Behälter eine Drehpumpe anbringen, deren Saugseite mit einer feststehenden Zuleitung für das gasförmige Medium verbunden ist. Bei solchen Vorrichtungen ist es auch schon bekannt, ein zusätzliches Rührorgan vorzusehen, das von der Pumpenwelle bewegt wird.Gas injection device for liquids To have a liquid with a To mix gaseous medium, devices have already been used in Attach a rotary pump to a container, the suction side of which is connected to a fixed Supply line for the gaseous medium is connected. In such devices it is also known to provide an additional agitator that is driven by the pump shaft is moved.

Einrichtungen der genannten Art sind im besonderen zur Behandlung von Wässern bestimmt, wenngleich sie auch zur Behandlung anderer Flüssigkeiten geeignet sind.Facilities of the type mentioned are especially used for treatment determined by water, although it is also suitable for the treatment of other liquids are.

Die Erfindung weist gegenüber den bekannten Einrichtungen einfachere Bauweise und besonders hohe Wirksamkeit auf. Sie ist dadurch gekennzeichnet, daß die Pumpe unterhalb des Spiegels der zu behandelnden Flüssigkeit angeordnet ist und daß das Ende der feststehenden eingetauchten Zuleitung für das gasförmige Medium das Pumpengehäuse bildet. The invention has, compared to the known devices, simpler ones Construction and particularly high effectiveness. It is characterized in that the pump is arranged below the level of the liquid to be treated and that the end of the fixed immersed supply line for the gaseous medium forms the pump housing.

In der Zeichnung sind zwei Ausführungsbeispiele des Erfindungsgegenstandes dargestellt, und zwar zeigt Fig. I einen Längsschnitt durch eine Ausführungsform und Fig. 2 einen entsprechenden Teilschnitt einer anderen Ausführungsform der Erfindung. The drawing shows two exemplary embodiments of the subject matter of the invention shown, namely Fig. I shows a longitudinal section through an embodiment and FIG. 2 shows a corresponding partial section of another embodiment of the invention.

Die in Fig. I dargestellte Vorrichtung weist einen Flüssigkeitsbehälter I auf, in dem sich die zu behandelnde Flüssigkeit und mindestens ein Be- wegungsorgan befinden, das eine Vermischung der Flüssigkeit mit einem Gas gestattet. Dieses Bewegungsorgan besteht im vorliegenden Fall aus einer in die Flüssigkeit einzutauchenden umlaufenden Pumpe 2. The device shown in Fig. I has a liquid container I, in which the liquid to be treated and at least one loading organ of movement are located, which allows mixing of the liquid with a gas. This locomotor organ consists in the present case of a circulating one to be immersed in the liquid Pump 2.

Unterhalb des Rades 2 befindet sich eine Verlängerung 12 der Welle 4. Diese Verlängerung trägt an ihrem freien Ende ein Rührorgan, z. B. eine Schraube I3. Durch die letztere soll ein Umrühren der Flüssigkeit im unteren Teil des Behälters I hervorgerufen werden, wobei dieses Umrühren in bestimmten Fällen zugleich dazu benutzt werden kann, feste Körper in Bewegung zu setzen, die auf dem Boden des Behälters 1 angeordnet werden, z. B. Eisenstückchen, wenn es sich darum handelt, mittels der Vorrichtung Abwässer od. dgl. mit Eisenhydroxyd zu behandeln. Below the wheel 2 there is an extension 12 of the shaft 4. This extension carries a stirring element at its free end, e.g. B. a screw I3. The latter is intended to stir the liquid in the lower part of the container I, with this stirring in certain cases at the same time Can be used to set solid bodies in motion on the bottom of the container 1 can be arranged, e.g. B. pieces of iron, if it is, by means of the Device to treat wastewater or the like with iron hydroxide.

Bei der in Fig. I dargestellten Ausführungsform der Erfindung dient das Gehäuse des Motors als Lager für die Gesamtbewegungsvorrichtung, und zwar mittels eines daran befestigten Flansches 14, der seinerseits an den Traversen 5 festgeschraubt wird. In the embodiment of the invention shown in FIG the housing of the motor as a bearing for the overall movement device, namely by means of a flange 14 attached to it, which in turn is screwed tightly to the crossbars 5 will.

Im übrigen bilden die Lager des Motors 6 die Lager für das ganze sich drehende Aggregat aus Motoranker, Antriebswelle 4, Pumpenrad 3 und Rührgerät I3. In addition, the bearings of the motor 6 form the bearings for the whole Rotating unit consisting of motor armature, drive shaft 4, pump wheel 3 and agitator I3.

Es ist zweckmäßig, einen Motor mit Drehzahlregelung zu verwenden. Er ist zu diesem Zweck mit einer doppelten Wicklung versehen, so daß die Pumpe auf zwei verschiedene Arten betrieben werden kann, je nachdem die Vorrichtung stärker oder schwächer belastet ist. It is advisable to use a speed control motor. For this purpose it is provided with a double winding so that the pump opens Two different ways can be operated, depending on the device more powerful or is less loaded.

Die beschriebene Einrichtung arbeitet wie folgt: Wenn beispielsweise Wasser behandelt werden soll, füllt man damit den Behälter 1 und setzt den Motor 6 in Gang. Die Pumpe 2 saugt dann Luft an. die über Durchlässe 15 in den Führungskanal 8 eintritt und in das Wasser durch das Pumpenrad 3 hineingeschleudert wird. Sowohl das Zentrifugalrad als die Schraube I3 rufen dabei eine Bewegung der gesamten Wassermasse und eine Diffusion der Luft in dieselbe hervor, wodurch eine Sauerstoffanreicherung des Wassers erfolgt. The device described works as follows: If, for example If water is to be treated, fill container 1 with it and start the engine 6 in progress. The pump 2 then sucks in air. which through passages 15 in the guide channel 8 enters and is thrown into the water by the pump wheel 3. As well as the centrifugal wheel as the screw I3 cause a movement of the entire water mass and diffusion of the air into it, thereby causing oxygenation of the water.

Für den Fall, daß das Wasser nicht nur oxydiert, sondern auch einer Behandlung mit Eisenhydroxyd unterworfen werden soll, schüttet man in den Behälter, wie oben angegeben, Eisenstückchen ein, die unter der Einwirkung der Schraube I3 mitgerissen werden. In the event that the water not only oxidizes, but one too Treatment with iron hydroxide is to be poured into the container, as indicated above, a piece of iron which, under the action of screw I3 get carried away.

Damit die Vorrichtung möglichst günstig arbeitet, läßt man sie kontinuierlich laufen, d. h. man führt kontinuierlich eine bestimmte Menge des Rohwassers zu und läßt eine entsprechende Menge behandelte Flüssigkeit abgeben. So that the device works as efficiently as possible, it is left continuous constantly. H. a certain amount of raw water is continuously fed in and allows a corresponding amount of treated liquid to be released.

Beim Ausführungsbeispiel der Erfindung gemäß Fig. 2 ist die Einrichtung im ganzen die gleiche wie in Fig. 1, lediglich das Zentrifugalrad 3 ist doppelseitig saugend ausgebildet. Es besteht zu diesem Zweck aus Schaufeln I6, die radial an einer Nabe der Welle 4 sitzen, ohne Zwischenscheibe. In the embodiment of the invention according to FIG. 2, the device is on the whole the same as in FIG. 1, only the centrifugal wheel 3 is double-sided trained to suck. For this purpose it consists of blades I6, which are radially attached a hub of the shaft 4 sit without an intermediate washer.

Im übrigen ist im Falle der Fig. 2 im Führungskanal 8 ein Lager I8 für die Welle 4 vorgesehen. Otherwise, in the case of FIG. 2, there is a bearing I8 in the guide channel 8 intended for shaft 4.

Natürlich könnte dieses Lager auch weggelassen sein, wenn die Lagerung im Motor 6 genügt.Of course, this bearing could also be left out when storing in motor 6 is sufficient.

Es ist zu bemerken, daß die Schaufeln I6 des Pumpenrades nach Fig. 2 entweder flach oder gekrümmt ausgebildet sein können oder beispielsweise auch aus Winkeleisen bestehen können. It should be noted that the blades I6 of the impeller according to Fig. 2 can be either flat or curved, or for example can consist of angle iron.

Zusätzlich zu den beschriebenen Ausführungsbeispielen könnte eine Regelungsvorrichtung vorgesehen werden, die es gestattet, die Luftzufuhr über die Durchlässe 15 zu regulieren. Zu diesem Zweck würde es beispielsweise genügen, auf der Führung 8 einen Abdeckschieber anzubringen, durch dessen Verschiebung die Öffnungen 15 mehr oder weniger abgedeckt werden könnten. In addition to the exemplary embodiments described, a Control device are provided that allows the air supply via the To regulate passages 15. For this purpose it would be sufficient, for example, on the guide 8 to attach a cover slide, by shifting the openings 15 could be more or less covered.

Anstatt nur eine Bewegungsvorrichtung zu ver wenden, könnten mehrere solche Einrichtungen vorgesehen werden, die entweder im gleichen Behälter oder in verschiedenen Behältern angeordnet werden. Instead of using just one movement device, several could such facilities are provided either in the same container or in different containers can be arranged.

Wenngleich die in der Zeichnung dargestellte Einrichtung in erster Linie zur Behandlung von Wässern bestimmt ist, könnte sie natürlich auch zur Behandlung anderer Flüssigkeiten benutzt werden. Wenn nicht Luft, sondern ein anderes Gas in der Flüssigkeit dispergiert werden soll genügt es, den Führungskanal 8 unter Schließung der Öffzungen 15 an eine entsprechende Gasleitung anzuschließen. Although the device shown in the drawing primarily Line is intended for the treatment of waters, it could of course also be used for treatment other liquids are used. If not air but another gas in the liquid is to be dispersed, it is sufficient to close the guide channel 8 of the openings 15 to be connected to a corresponding gas line.
