Abstract
In the parent patent was disclosed a device for auto-aerating or -gasifying fluds in containers, esp. for the aerobic propagation of micro-organisms such as yeasts, fungi, and bacteria, with a circulating pump having an enclosed centrifugally-acting rotor, and above the rotor a fluid guiding duct with a venturi constriction, at the narrowest point of which there are inlets for the gas. In the patent of addition the gas inlets into the constriction are formed by a number of small adjustable tubes of the same or different dia. and length, positioned in different planes, projecting at right angles into the flow and chamfered at their outlets downwards. The gas lead may be connected to a supply of compressed air. The gasification is effected without the need for compressors, and adequate quantities of air or gas thoroughly dispersed by suction are assured.
Description
Die Erfindung betrifft eine Vorrichtung nach Patentanspruch des Hauptpatentes zur Belüftung von Flüssigkeiten.
Das Hauptpatent beschreibt eine Vorrichtung zur Belüftung von Flüssigkeiten mit einer Kreiselpumpe, die mit einem axial ansaugenden Schleuderrad versehen ist, das an der Eintrittsöffnung eine venturiartige Verengung besitzt, wobei mehrere kleine Zufuhrrohre für Luft oder andere Gase in die Verengung hineinragen.
Diese Rohre sind in verschiedenen Ausführungen bezüglich Länge und Durchmesser beschrieben.
Gegenstand und Aufgabe der Zusatzerfindung ist eine weitere Ausführungsform der Vorrichtung zur selbstansaugenden Belüftung von Flüssigkeiten und Gasen.
Die Aufgabe wird gelöst durch Schaffung einer Vorrichtung zur Belüftung von Flüssigkeiten der anfangs genannten Art. die dadurch gekennzeichnet ist, dass sie einen Leitzylinder aufweist. der an der Eintrittsöffnung in die venturiartige Verengung einmündet und dass die Zuführungsrohre die Verengung bildende Begrenzungswände mit nach innen gerichteten Ausströmöffnungen durchdringen.
Der Leitzylinder geht so in die Verengung über, dass die Flüssigkeit stark beschleunigt wird und durch die Venturiwirkung Luft über die Rohre aus dem Luftzuführungsrohr, das mit der Aussenluft verbunden sein kann, ansaugt. Hier erfolgt eine Dispersion der Luft in der Flüssigkeit, bevor diese Vordispersion vom Schleuderrad erfasst wird und der eigentlichen intensiven Vermischung der Gase mit der Flüssigkeit zugeführt wird.
Durch diese Vorrichtung erfolgt also eine sehr intensive Vermischung der Gasphase mit der Flüssigkeitsphase.
Die folgende Figur gibt beispielsweise eine solche Vorrichtung wieder.
Die Figur zeigt die Vorrichtung im Längsschnitt.
Auf der Welle 1 ist das Pumpenlaufrad 2 angebracht. Der Leitzylinder 3 wird gegen das Pumpenlaufrad 2 stark verengt.
In den Verengungsraum 4 ragen in verschiedenen Ebenen kleine Rohre 5, die über ein gemeinsames Ringrohr 6 und über das Luftzuführungsrohr 7 mit der Aussenluft verbunden sind. Die kleinen Rohre 5 können nach unten abgeschrägt sein. Das Pumpenlaufrad 2 wird durch ein ausserhalb der Kesselwand 8 liegenden Antrieb 9 angetrieben.
Die Flüssigkeit wird über das Pumpenlaufrad 2 aus dem Leitzylinder 3 angesaugt. Durch die venturiartige Verengung 4 im unteren Teil des Leitrohres 3 wird die Flüssigkeit so stark beschleunigt, dass sie ein Vakuum über die in die Verengung 4 hineinragenden kleinen Rohre 5, das Ringrohr 6 und das Luftzuführungsrohr 7 erzeugt und Luft selbsttätig in den Flüssigkeitsstrom angesaugt wird. Die Wirkung wird durch die nach unten abgeschrägten Rohre 5 noch verstärkt.
Je mehr Rohre 5 in verschiedenen Ebenen angebracht sind.
um so stärker ist die Vermischung. Die so entstandene Dispersion durchströmt nun das Pumpenlaufrad 2 und wird nochmals beschleunigt.
Durch die Kummulierung der Effekte entsteht eine für das Wachstum vieler Organismen mit einem hohen Sauerstoffbedarf ausgezeichnete Belüftung.
Ein weiterer Vorteil der Erfindung ist die Einsparung von Kompressoren durch die selbstansaugende Wirkung.

**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
The invention relates to a device according to claim of the main patent for aeration of liquids.
The main patent describes a device for aerating liquids with a centrifugal pump, which is provided with an axially sucking impeller which has a venturi-like constriction at the inlet opening, with several small supply pipes for air or other gases protruding into the constriction.
These tubes are described in different versions with regard to length and diameter.
The subject matter and task of the additional invention is a further embodiment of the device for the self-aspirating ventilation of liquids and gases.
The object is achieved by creating a device for ventilating liquids of the type mentioned at the beginning, which is characterized in that it has a guide cylinder. which opens into the venturi-like constriction at the inlet opening and that the supply pipes penetrate the boundary walls forming the constriction with inwardly directed outflow openings.
The guide cylinder merges into the constriction in such a way that the liquid is strongly accelerated and, through the Venturi effect, sucks in air through the pipes from the air supply pipe, which can be connected to the outside air. Here, the air is dispersed in the liquid before this predispersion is detected by the centrifugal wheel and the actual intensive mixing of the gases with the liquid is carried out.
This device therefore results in a very intensive mixing of the gas phase with the liquid phase.
The following figure shows, for example, such a device.
The figure shows the device in longitudinal section.
The pump impeller 2 is attached to the shaft 1. The guide cylinder 3 is greatly narrowed towards the pump impeller 2.
In the constriction space 4, small pipes 5 protrude in different planes, which are connected to the outside air via a common ring pipe 6 and via the air supply pipe 7. The small tubes 5 can be beveled downwards. The pump impeller 2 is driven by a drive 9 located outside the boiler wall 8.
The liquid is sucked in from the guide cylinder 3 via the pump impeller 2. The venturi-like constriction 4 in the lower part of the guide tube 3 accelerates the liquid so much that it creates a vacuum through the small tubes 5 protruding into the constriction 4, the annular tube 6 and the air supply tube 7 and air is automatically sucked into the liquid flow. The effect is reinforced by the downward sloping tubes 5.
The more tubes 5 are attached in different levels.
the greater the intermingling. The resulting dispersion now flows through the pump impeller 2 and is accelerated again.
The cumulation of the effects creates excellent ventilation for the growth of many organisms with a high oxygen requirement.
Another advantage of the invention is the saving on compressors due to the self-priming effect.
