Description

  

   <Desc/Clms Page number 1> 
 
 EMI1.1 
 tangentialen   Zuführungsrohre-l   und 2-- sind angeschweisst. Im kegeligen Teil des äusseren Behälters ist der   Flansch --8-- angeschweisst,   in dem das zylindrische   Rohrstück --3-- eingeschraubt   wird. Aussen von diesem Flansch --8-- ist der Luftansaugteil --5-- aufgeschraubt, in dem wieder das Ansaugleitblech --6-- angeschraubt ist. Das ringförmige Ansaugleitblech --7-- ist mit radialen Schrauben am Teil --6-- befestigt. 



   Der Nebenkopf besteht aus einem koaxialen zylindrischen bzw. kegeligen, durch einen Deckel verschlossenen   Behälter-9-,   einem radialen Flüssigkeitszuführrohr --10-- und einem Ansaugleit-   blech  
Der   Behälter --9-- ist   in massiver Schweisskonstruktion ausgeführt und kann in einer Querschnittsform, ebenfalls wie der Teil -11- variabel (kreisförmig, rechteckig, oval-langlochförmig, schlitzförmig usw.) ausgeführt werden. Diese Querschnitts-Flexibilität gilt für jedes einzelne Ansaugleitblech.

   Die äussere Form des Nebenkopfes kann durch eine Verfeinerung der Ringdüse noch verschieden gestaltet werden (zylindrischer Oberteil mit radialer   Flüssigkeitszuführung - kegelige     Ringdüse - an   Stelle eines zylindrischen Auslaufes ein kegeliger Diffusor gleich Venturi-Prinzip). 



  Dieselben Gestaltungsrichtlinien gelten für die Ansaugleitbleche --11, 6 und 7--. 



   Die Treibmedien, z. B. Abwasser und Flüssigkeit, gelangen durch die beiden aus entgegengesetzten Richtungen kommenden Leitungen-l und   2-- in   die beiden   Behälter --3   und 4--, wobei 

 <Desc/Clms Page number 2> 

 gegenläufige Drallströmungen erzeugt werden, die auch bei der Weiterströmung nach unten erhalten bleiben. Durch die Öffnung im   Teil --5-- sowie   die Ringspalte zwischen Teil --6 und 7-- sowie zwischen Teil --7 und 11-- wird nun gemäss dem bekannten Injektorprinzip Luft angesaugt und zufolge der gegenläufig rotierenden Drallströmungen innig mit dem Treibmedium vermischt. Die in   Teil --5-- angesaugte   Luft gelangt in den Ringspalt zwischen Teil-3 und 6--.

   Zusätzlich gelangt durch das aussen angeordnete   Zuführrohr --10-- Flüssigkeit   zu dem bereits vorhandenen Luft-Flüssigkeitsgemisch, wobei eine Vermischung weiter gefördert wird. 



   Der Nebenkopfausgang wird am Fallrohr angebracht, saugend oder nichtsaugend. Das Gerät kann man in Massivbauweise sowie als einfache Blechkonstruktion herstellen.

 EMI1.1
 Tangential feed pipes-1 and 2-- are welded on. The flange --8-- is welded into the conical part of the outer container and the cylindrical pipe section --3-- is screwed into it. The air intake section --5-- is screwed onto the outside of this flange --8--, in which the intake guide plate --6-- is screwed on again. The ring-shaped suction baffle --7-- is attached to part --6-- with radial screws.



   The secondary head consists of a coaxial cylindrical or conical container-9- sealed by a lid, a radial liquid feed pipe --10-- and an intake baffle
The container --9-- is made of solid welded construction and can be designed in a cross-sectional shape, like the part -11- variable (circular, rectangular, oval-elongated, slit-shaped, etc.). This cross-sectional flexibility applies to every single intake baffle.

   The outer shape of the secondary head can be designed differently by refining the ring nozzle (cylindrical upper part with radial liquid supply - conical ring nozzle - instead of a cylindrical outlet, a conical diffuser similar to the Venturi principle).



  The same design guidelines apply to intake guide plates --11, 6 and 7--.



   The driving media, e.g. B. waste water and liquid, get through the two lines coming from opposite directions-l and 2-- into the two tanks --3 and 4--, whereby

 <Desc / Clms Page number 2>

 opposing swirl flows are generated, which are retained even when the flow continues downward. Through the opening in part --5-- and the annular gaps between part --6 and 7-- as well as between part --7 and 11--, air is now sucked in according to the well-known injector principle and due to the counter-rotating swirling currents intimately with the propellant mixed. The air sucked in part --5-- enters the annular gap between part-3 and 6--.

   In addition, --10-- liquid reaches the already existing air-liquid mixture through the externally arranged feed pipe, whereby mixing is further promoted.



   The secondary head outlet is attached to the downpipe, suction or non-suction. The device can be made in solid construction as well as a simple sheet metal construction.
