Description

Die Erfindung betrifft eine Vorrichtung zum feinblasigen Belüften von Wasser mit einem Stützrohr und einem darauf befindlichen, mit feinen Schlitzen versehenen, aus Gummi od. dgl. bestehenden, das Stützrohr umschliessenden Mantel, der an seinen Enden durch ihn umfassende Schellen fixiert ist, wobei das Stützrohr an einer Halterung befestigt ist, von der aus zwischen Mantel und Stützrohr vorgespannte Luft geleitet wird.The invention relates to a device for fine bubbles Vent water with a support tube and one on top located, with fine slits, made of rubber or the like. Existing, enclosing the support tube Coat, the jingles encircling it at its ends is fixed, the support tube on a bracket is attached from between the jacket and support tube biased air is passed.

In bekannter Weise sind diese Halterungen an einem Verteilerrohr gelagert, dem eine Vielzahl von Halterungen und Stützrohre mit geschlitzten Mänteln zugeordnet sind. Dabei erstrecken sich die Stützrohre im Winkel, und zwar vorzugsweise rechtwinkelig zur Verteilerleitung, um so eine grössere Anzahl Stützrohr mit den geschlitzten Mänteln auf engem Raum unterbringen zu können.In a known manner, these brackets are on one Distribution pipe stored, which a variety of brackets and support tubes with slotted jackets are assigned. The support tubes extend at an angle, namely preferably at right angles to the distribution line, all the more so a larger number of support tubes with the slotted ones To be able to accommodate coats in a small space.

Es ist ferner bekannt, die Stützrohre geflutet zu betreiben, um unnötige Auftriebskräfte auszuschliessen, jedoch sind alle Stützrohre fest mit der Halterung und diese wiederum unverrückbar mit dem Verteilerrohr verbunden. Im allgemeinen werden dazu Verschraubungen verwendet.It is also known to flood the support tubes operate in order to exclude unnecessary buoyancy forces,  however, all support tubes are fixed to the bracket and this in turn immovable with the manifold connected. Generally screw connections are used used.

Oft besteht jedoch der Wunsch, bei einem Verteilerrohr Abzweigungen bzw. Stützrohre mit Mänteln unterschiedlicher Länge zu benutzen, wenn dies z. B. aus räumlichen Gründen zweckmässig erscheint. Dies trifft sowohl für die an einem Verteilerrohr paarweise gegenüber liegenden, fluchtenden Stützrohre als auch für in Längsrichtung der Verteilerrohre aufeinander folgenden Stützrohre zu.However, there is often a desire for a manifold Branches or support pipes with jackets to use different lengths, if this z. B. from spatial reasons seems appropriate. This is true both for the opposite in pairs on a manifold lying, aligned support tubes as well as in Longitudinal direction of the distribution pipes in succession Support tubes too.

Der Erfindung liegt demgemäss die Aufgabe zugrunde, die Verbindung der Stützrohre mit ihren Halterungen so zu vereinfachen, dass für die Stützrohre handelsübliche - meist aus hartem Kunststoff bestehende - Rohre benutzt werden können, die dann ohne weiteres mit gleicher oder unterschiedlicher Länge eingesetzt werden können.The invention is accordingly based on the object Connect the support tubes to their brackets simplify that commercially available for the support tubes - mostly made of hard plastic - used pipes which can then be easily with the same or different lengths can be used.

Zur Lösung dieser Aufgabe ist erfindungsgemäss das Stützrohr in eine rohrförmige Halterung eingeschoben und zudem ist das freie Ende des Mantels mittels Schelle auf dem Stützrohr und das innere Ende des Mantels mittels Schelle auf der Halterung befestigt.To achieve this object, the invention is Support tube inserted into a tubular holder and In addition, the free end of the jacket is open using a clamp the support tube and the inner end of the jacket by means of Clamp on the bracket attached.

Unter diesen Voraussetzungen können an sich beliebig lange bzw. beliebig kurze Stützrohre benutzt werden, denen dann die aus einem Elastomer bestehenden, entsprechend abgelängten Mäntel zugeordnet werden. Die Tatsache, dass die Mäntel an einem Ende (am freien Ende der Vorrichtung) am Stützrohr befestigt, hingegen am inneren Ende (der Halterung zugekehrt) sind, führt zu einer gwünschten Stabilierung des Stützrohres in der Weise, dass das Stützrohr unerwünschte Längsverschiebungen nicht ausführen kann. Unter diesen Bedingungen ist es sogar möglich, lediglich auf einer Seite eines Verteilerrohres einen Mantel mit zum Austritt der Luftbläschen geeigneten Schlitzen zu versehen.Under these conditions, anything can be done in itself long or short support tubes are used, which then consist of an elastomer, can be assigned to coats cut to length. The  Fact that the coats at one end (at the free end the device) attached to the support tube, on the other hand inner end (facing the bracket) leads to a desired stabilization of the support tube in the Way that the support tube undesirable Can not perform longitudinal displacements. Under these It is even possible to only use one condition Side of a manifold with a jacket to exit to provide suitable slots in the air bubbles.

Um sicherzustllen, dass bei der an sich schwimmenden Lagerung des Stützrohres dieses keine ungewollten Lateralbewegungen ausführen kann, gleichzeitig aber zu gewährleisten, dass die vorgespannte Luft von der Verteilerleitung über die Halterung zwischen das Stützrohr und den Mantel gelangen kann, ist die dem Stützrohr zugekehrte Fläche der Halterung mit Vorsprüngen oder Kanälen versehen.To make sure that the floating one Storage of the support tube this no unwanted Can perform lateral movements, but at the same time too ensure that the biased air from the Distribution line over the bracket between the Support tube and the jacket can get that Support tube facing surface of the bracket with protrusions or channels.

Eine solche Ausbildung der Vorrichtung ermöglicht vergleichsweise lange Stützrohre, wobei Stützrohre mit einer Länge von 4-8 m möglich sein. Bei derart langen Stützrohren, können schellenartige Bodenverankerungen benutzt werden, um Schwingungen auszuschalten bzw. Verformungen entgegenzuwirken.Such a design of the device enables comparatively long support tubes, with support tubes with a length of 4-8 m may be possible. With such a long time Support pipes, can be clamp-like floor anchors be used to switch off vibrations or To counteract deformations.

Die Verbindung zwischen dem Verteilerrohr und der Halterung kann an sich beliebig gestaltet werden; vorzugsweise kommen jedoch teilbare Schellen in Betracht, um eine Lösbarkeit sicherzustellen. The connection between the manifold and the Bracket can be designed in any way; divisible clamps are preferred, however, to ensure solvability.

Ein z. B. aus einem hart eingestellten Kunststoff bestehendes Verteilerrohr 1 zum Zuführen vorgespannter Luft weist an seiner Unterseite eine Durchbrechung 2 auf, in die abgedichtet ein Stutzen 3 hineinragt. Der Stutzen 3 ist Bestandteil eines Unterteils 4 einer geteilten Schelle 5 mit Gelenkstelle 6 und Verschluss 7 zum Zusammenhalten der beiden Schellenteile.A z. B. made of a hard set plastic manifold 1 for supplying biased air has on its underside an opening 2 , into which a nozzle 3 protrudes sealed. The connector 3 is part of a lower part 4 of a split clamp 5 with a joint 6 and closure 7 for holding the two clamp parts together.

Das Unterteil 4 geht einstückig in eine Halterung 8 über, die zu beiden Seiten in einen etwa rohrförmigen Abschnitt 9, 10 übergehen, die je die Schelle 5 seitlich überragen und sich im rechten Winkel zum Verteilerrohr 1 erstrecken. The lower part 4 merges in one piece into a holder 8 , which merges on both sides into an approximately tubular section 9 , 10 , which each protrude laterally from the clamp 5 and extend at right angles to the distributor pipe 1 .

An ihrer Innenseite sind die Abschnitte 9, 10 mit Vorsprüngen in Form von axial verlaufenden Rippen 11 versehen, wobei der durch die Vorsprünge bestimmte lichte Durchgangsquerschnitt in den Abschnitten 9, 10 dem Aussendurchmesser eines aus hartem Kunststoff bestehenden Stützrohres 12 entspricht.On the inside, the sections 9 , 10 are provided with projections in the form of axially extending ribs 11 , the clear passage cross section determined by the projections in sections 9 , 10 corresponding to the outside diameter of a support tube 12 made of hard plastic.

Demgemäss kann das Stützrohr 12 beliebig weit eingeschoben und so symmetrisch, aber auch asymmetrisch in Bezug auf die Halterung 8 angeordnet werden. Das Stützrohr 12 ist an beiden Enden von einem dünnen, membranartigen Mantel 13, 14 umschlossen, der gemäss Fig. 3 im Wirkbereich W mit einer grossen Zahl feiner Schlitze 15 versehen, um den Austritt feiner Bläschen zu ermöglichen.Accordingly, the support tube 12 can be inserted as far as desired and thus be arranged symmetrically, but also asymmetrically with respect to the holder 8 . The support tube 12 is enclosed at both ends by a thin, membrane-like jacket 13 , 14 which, according to FIG. 3, is provided with a large number of fine slots 15 in the effective area W in order to allow fine bubbles to emerge.

Zur Stabilisierung des an sich schwimmend gelagerten Stützrohres 12 werden die freien Enden beider Mäntel 13, 14 durch Schellen 16 mit den freien Enden des Stützrohres 12 verbunden. Die inneren Enden der Mäntel 13, 14 werden hingegen auf den Enden der Abschnitte 9, 10 ebenfalls durch Schellen 17 fest verbunden. Somit ist das durchgehende Stützrohr 12 gegen axiale Verlagerungen ausreichend gesichert.To stabilize the floating support tube 12 , the free ends of both jackets 13 , 14 are connected by clamps 16 to the free ends of the support tube 12 . The inner ends of the jackets 13 , 14 , however, are also firmly connected to the ends of the sections 9 , 10 by clamps 17 . The continuous support tube 12 is thus adequately secured against axial displacement.

Die vorgespannte Luft gelangt aus der Verteilerrohr 1 über den Stutzen 3 und die zwischen den Rippen 11 befindlichen Kanäle 19 in den Raum bei 20 und von dort aus zwischen Mantel 13, 14 und Stützrohr 12. Damit kann die Luft über die Schlitze 15 in das Wasser eintreten.The prestressed air passes from the distributor pipe 1 via the connector 3 and the channels 19 located between the ribs 11 into the space at 20 and from there between the jacket 13 , 14 and the support pipe 12 . This allows the air to enter the water through the slots 15 .

Für den Fall, dass in Bezug auf das Verteilerrohr 1 lediglich eine einseitige Belüftung stattfinden soll, wird ein ganz kurz gehaltener Mantel 13 bzw. benutzt, der zwar mittels Schellen 16, 17 befestigt wird, jedoch keine Schlitze 15 aufweist.In the event that only one-sided ventilation is to take place with respect to the distributor pipe 1 , a very short jacket 13 or is used, which is fastened by means of clamps 16 , 17 , but has no slots 15 .
