Description

BeschreibungDescription

Begasungsrührwerk, insbesondere zum Eintrag von Luft in Flüssigkeiten unter gleichzeitigem Mischen derselben.Gassing agitator, particularly for introducing air into liquids while simultaneously mixing them.

Stand der TechnikState of the art

Begasungsrührer üblicher Bauart werden entweder mit Hohlwellen ausgerüstet, durch die dann mittels Kompressor Druckluft durch eine zentrische Öffnung am Propeller in die Flüssigkeit eingeblasen wird oder über ein feststehendes, um die Welle geführtes Mantelrohr, durch eine Turbine am Wellenende mit hohem Geräuschpegel Luft eingesogen wird.Gassing stirrers of the usual design are either equipped with hollow shafts through which compressed air is blown into the liquid by means of a compressor through a central opening on the propeller or through a fixed jacket pipe that is guided around the shaft and through a turbine at the end of the shaft with a high noise level.

Problemproblem

Der im Anspruch 1 angegebenen Erfindung liegt das Problem zugrunde, ohne Fremdgeräte einen Lufteintrag zu erreichen und durch eine einfache Konstruktion Sonderausführungen wie Hohlwellenmotoren zu umgehen. Ferner möchte man den wegen der Bewegung der Flüssigkeit sehr stabil auszuführenden Einbau eines feststehenden Mantelrohres vermeiden.The invention specified in claim 1 is based on the problem of achieving air intake without external devices and avoiding special designs such as hollow shaft motors through a simple construction. Furthermore, the installation of a fixed jacket pipe, which has to be carried out very stably due to the movement of the liquid, is to be avoided.

Erfindunginvention

Dieses Problem wird mit den Maßnahmen des Anspruches 1 gelöst.This problem is solved by the measures of claim 1.

Vorteilhafte Wirkungen der ErfindungAdvantageous effects of the invention

Mit der Erfindung wird im angegebenen Anwendungsfall erreicht, daß ohne zusätzliche Geräte Luft in Flüssigkeiten eingetragen und diese gleichzeitig gemischt werden können. Der dabei entstehende Geräuschpegel ist sehr niedrig. Ferner erlaubt die einfache Konstruktion die Ausführung in chemisch hochresistenten Werkstoffen wie z.B. PTFE oder PVDF und damit den Einsatz in aggressiven Flüssigkeiten zu kostengünstigen Preisen.In the specified application, the invention achieves that air can be introduced into liquids without additional equipment and these can be mixed at the same time. The resulting noise level is very low. Furthermore, the simple design allows the device to be made from highly chemically resistant materials such as PTFE or PVDF and thus use in aggressive liquids at low prices.

WeiterbildungenFurther training

Vorteilhafte Ausgestaltungen sind in den Ansprüchen 3, 5 und 7 angegeben.Advantageous embodiments are specified in claims 3, 5 and 7.

Mit dem Anspruch 3 kann durch die Form und Größe der Düsen die Größe der Luftblasen beeinflußt werden.According to claim 3, the size of the air bubbles can be influenced by the shape and size of the nozzles.

Mit dem Anspruch 5 kann durch die Anzahl der Flügelblätter die Menge des Lufteintrags beeinflußt werden.According to claim 5, the amount of air introduced can be influenced by the number of blades.

Mit dem Anspruch 7 kann durch die Form und Steigung die Intensität des Mischens bestimmt werden.With claim 7, the intensity of mixing can be determined by the shape and slope.

Darstellung der ErfindungDescription of the invention

Ein Ausführungsbeispiel wird anhand der Figur 1 gezeigt. Es zeigt:An example embodiment is shown in Figure 1. It shows:

1 die Kernwelle1 the core wave

2. das Mantelrohr2. the jacket pipe

3 den Diffusor3 the diffuser

4 den Propeller4 the propeller

5 die Flügelblätter5 the wing blades

6 den Leitkanal6 the guide channel

7 die Düsen7 the nozzles

In dem Hohlraum des Diffusors bildet sich bei Rotation eine Strömung wie skizziert aus. Die bei Stillstand eingedrungene Flüssigkeit wird ausgetragen und durch das über dem Flüssigkeitsniveau endende Mantelrohr Luft nachgezogen. Durch den Unterdruck an den Flügelblatt-Kanten wird über die Düsen Luft gezogen und durch den gleichzeitigen Mischeffekt stark und gleichmäßig im Behälter verwirbelt. Da dieser Vorgang in der Flüssigkeit stattfindet, entsteht durch die starke Schall-Dämpfung keinerlei belästigendes Geräusch, auch nicht über die öffnung des Mantelrohres unterhalb des Motors.When the diffuser is rotating, a flow is formed in the cavity of the diffuser as shown. The liquid that has entered when the device is at a standstill is discharged and air is drawn in through the jacket tube that ends above the liquid level. The negative pressure at the edges of the blades draws air through the nozzles and the simultaneous mixing effect causes it to swirl strongly and evenly in the container. Since this process takes place in the liquid, the strong sound insulation means that no annoying noise is generated, not even through the opening of the jacket tube below the motor.
