Description
Vorrichtung zum Verteilen von Gasen oder Luft in Flüssigkeiten DerErfindungsgegenstand gehört zur kasse der Vorrichtungen, um Gase, z. B. Sohlensäure, oder auch Luft in Flüssigkeiten, z. B.Apparatus for distributing gases or air in liquids. The subject of the invention belongs to the cash register of the devices to gases, z. B. sole acid, or air in Liquids, e.g. B.
\Vasser, in Form möglichst kleiner Gasbläschen fein zu verteilen, etwa für Zwecke der Belüftung des Wassers oder auch für Badezwecke.\ Vasser to finely distribute in the form of gas bubbles as small as possible, for example for the purpose of aeration of the water or for bathing purposes.
Die bisher bekannten Vorrichtungen dieser Art bestanden aus einem inneren Luftzuführungsrohr, welches mit Luftverteilungslöchern versehen war, einem dieses mit Abstand umschließenden Austrittsrohr, das ebenfalls mit Löchern versehen war, und einer den Zwischenraum zwischen innerem und äußerem Rohr ausfüllenden porösen, beispielsweise aus Faserstoft gebildeten Masse, durch die die feine Verteilung der aus dem Innen- nach dem Außenrohr austretenden Luft, die dann in die Flüssigkeit in Form von Bläschen eintreten, bewirkt wurde. The previously known devices of this type consisted of one inner air supply pipe, which was provided with air distribution holes, a this at a distance enclosing the outlet pipe, which is also provided with holes was, and a porous space between the inner and outer tube, For example, mass formed from fibrous material, through which the fine distribution of the from the inner to the outer tube exiting air, which then enters the liquid occur in the form of vesicles.
Diese Ausbildungsweise ist technisch umstündlich und auch in ihrer Wirkung unvollkommen, weil die erforderliche Gleichmäßigkeit der porösen Füllung im Innen- und Außen roh r, insbesondere im Dauerbetrieb und unter Berücksichtigung des Umstandes, daß die poröse Füllmasse durch die Flüssigkeit befeuchtet wird, schwer aufrechterhalten werden kann. This training method is technically hourly and also in theirs Effect imperfect because of the required evenness of the porous filling inside and outside raw r, especially in continuous operation and taking into account the fact that the porous filling material is moistened by the liquid, difficult can be sustained.
Zum Unterschied von diesen bekannten Gas- oder Luftverteilungsvorrichtungen in Flüssigkeiten besteht diejenige nach der vorliegenden Erfindung lediglich aus zwei im Pallsitz, also ohne wesentliche Luftzwischenräume ineinanderschiebbaren Rohren, deren inneres Rohr mit Luftdurchtrittslöchern versehen ist, während das äußere in versetzbarer Ebene entsprechende Luftaustrittslöcher oder Schlitze aufweist. In contrast to these known gas or air distribution devices in liquids, that according to the present invention consists only of two can be pushed into one another in a full seat, i.e. without any significant air gaps Pipes, the inner pipe of which is provided with air passage holes, while the outer has corresponding air outlet holes or slots in displaceable plane.
Um nun einen Austritt der Luft in fein verteilter Form aus dem Innenrohr nach dem Außenrohr trotz des Paßsitzes zu ermöglichen, ist die Außenfläche des Innenrohrs oder die Innenfläche des Außenrohrs oder beide mit sehr feinen Riefungen versehen. In order to allow the air to exit the inner tube in a finely distributed form after the outer tube despite the snug fit is the outer surface of the inner tube or the inner surface of the outer tube or both are provided with very fine grooves.
Diese Riefungen werden dabei als dicht aneinanderliegende Kreisriefungen oder als durchlaufende Spiralriefungen ausgebildet.These corrugations are called closely spaced circular corrugations or designed as continuous spiral grooves.
Um die durch die Löcher des Innenrohres austretende Luft gleichmäßig zu verteilen, sind diese Löcher des Innenrohrs auf der Außenseite desselben durch eine in Längsrichtung durchlaufende schmale Nut miteinander verbunden. Versuche haben ergeben, daß bei derartiger Ausgestaltung der mit Paßsitz ineinanderschiebbaren Luftverteilungsrohre eine außerordentlich feine, dauernd gleichmäßige, den Zustand der Flüssigkeit nicht beeinflussende Verteilung über die ganze Länge des Systems in Bläschenform herbeigeführt wird. Von einer porösen, die geschilderten Nachteile mit sich bringenden Füllmasse wird also bei der neuen Luftverteilungsvorichtung Abstand genommen.Around the air exiting through the holes in the inner tube evenly to distribute, these holes of the inner tube are on the outside of the same through a narrow groove running in the longitudinal direction connected to one another. try have shown that with such a configuration the nestable with a snug fit Air distribution pipes an extremely fine, permanently uniform, the condition distribution over the entire length of the system, which does not affect the liquid is brought about in the form of bubbles. From a porous one, the disadvantages outlined The filling compound that is brought with it is therefore used in the new air distribution device Distanced.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht, und zwar zeigt: Abb. I einen Längsschnitt, Abb. 2 eine Aufsicht auf die Vorrichtung, während Abb. 3 teilweise im Schnitt, teilweise in Draufsicht das innereLuftverteilungsrohr veranschaulicht. In the drawing, the subject matter of the invention is illustrated, for example, namely shows: Fig. I a longitudinal section, Fig. 2 is a top view on the device, while Fig. 3 partly in section, partly in plan view illustrates the inner air distribution pipe.
In der Zeichnung stellt I das durch Boden 1' geschlossene Innenrohr dar, das mit Paßsitz in das gleichfalls durch Boden 2' geschlossene Außenrohr 2 geschoben werden kann. Das Innenrohr I besitzt in bestimmten Abständen Luftdurchtrittsöffnungen 3 und auf seiner Außenfläche eine diese verbindende Nut 4, so daß die durch die Öffnungen 3 hindurchtretende Luft längs der Nut 4 gleichmäßig verteilt wird. In zu den Löchern 3 versetzbarer Ebene besitzt das Außenrohr 2 Durchtrittsöffnungen oder besser etwas schräg gestellte Schlitze 6. Die Außenfläche des Innenrohrs oder aber auch die Innenfläche des Außenrohrs, evtl. beide, sind nun mit außerordentlich feinen, im Durchmesser nur geringe Millimeter betragenden Riefen oder Rillen versehen, in Form dicht aneinanderliegender Kreise oder in Form einer Spiralriefung. Die aus den Löchern austretende und durch die Nut 4 verteilte Luft strömt durch die Riefen hindurch und gelangt in feinster Verteilung zu dem Schlitz 6 aus dem sie in Bläschenform und gleichmäßig im Außenrohr 2 verteilt in die umgebende Flüssigkeit eintritt. In the drawing, I represents the inner tube closed by the bottom 1 ' represents, with a snug fit in the outer tube 2, which is also closed by the bottom 2 ' can be pushed. The inner tube I has air passage openings at certain intervals 3 and on its outer surface a connecting groove 4 so that the through the Openings 3 passing air along the groove 4 is evenly distributed. In the outer tube has 2 passage openings or better slightly inclined slots 6. The outer surface of the inner tube or but also the inner surface of the outer tube, possibly both, are now extraordinary provide fine grooves or grooves with a diameter of only a few millimeters, in the form of tightly spaced circles or in the form of a spiral groove. From The air exiting the holes and distributed through the groove 4 flows through the grooves through and arrives in the finest distribution to the slot 6 from which it is in the form of a bubble and evenly distributed in the outer tube 2 enters the surrounding liquid.
Die Zuführung der Luft zum Innenrohr, das bis zur Stirnfläche des Außenrohrs mit seiner freien Öffnung reicht, erfolgt durch einen auf das Endgewinde 7 des Außenrohrs aufschraubbaren Zuführungsnippel. The supply of air to the inner tube, which extends up to the face of the The outer tube with its free opening is sufficient, is carried out through one on the end thread 7 of the outer tube screw-on feed nipple.
Selbstverständlich können auch mehrere solcher Luftserteilungsvorrichtungen parallel zueinander an einer gemeinsamen Luft oder Gaszuführungsleitung angeschlossen sein. Of course, several such air distribution devices can also be used connected in parallel to one another to a common air or gas supply line be.
Wenn die Außenfläche des Innenrohrs und die Innenfläche des Außenrohrs Riefungen tragen, ist es möglich, durch eine geringe, etwa durch Verschraubung herbeiführbare Verschiebung des Innenrohrs zum Außenrohr die Durchtrittsquerschnitte für die Luft, die durch die Riefen gebildet werden, zu verhindern und dadurch die Größe der Luftbläschen zu beeinflussen. When the outer surface of the inner pipe and the inner surface of the outer pipe Carrying grooves, it is possible to bring about a slight, for example by screwing Displacement of the inner pipe to the outer pipe the passage cross-sections for the air, which are formed by the grooves, and thereby prevent the size of the air bubbles to influence.
