. Vorrichtung zur Belüftung von Wasser insb. Abwasser. Device for aeration of water, especially waste water
Die Erfindung betrifft eine Vorrichtung zum Belüften von Wasser insb. Abwasser mit in einer Vielzahl vorgesehenen, auf perforierten Stützrohren befindlichen, aus Gummi od. dgl. bestehenden, feinperforierten, an ihren Enden abgebundenen Mänteln.The invention relates to a device for ventilation of water, especially wastewater with a large number of provided on perforated support pipes, Made of rubber or the like, finely perforated coats tied at their ends.
Bei den bekannten Vorrichtungen dieser Art haben die Mantel die Aufgabe, die ihnen über die Stützrohre zugeführte Druckluft in feinst verteilter Form in das Wasser abzugeben· Die Tatsache, dass diese Mäntel aus Gummi oder gummiähnlichen Kunststoffen bestehen, bringt den Vorteil mit sich, dass sich die im Mantel befindlichen, schlitzartigen Perforationen nur öffnen, wenn sie von innen her unter Druckluft steh&n bzw. geschlossen sind, wenn sie ausser Betrieb sind und keine Druckluft in das Wasser abgeführt werden soll. Die bekannten Vorrichtungen dieser Art sind aber deshalb sehr aufwendig, weil die in kurzen Längen befindlichen Mantel auf geringfügig längere Stützrohre aufgezogen sind, die ihrerseits tannenbaumartig an eine Sammelleitung angeschlossen sind. Von dieser Sammelleitung gehen also die einzelnen Stützrohre als Abzweigung ab, und zwar meist an gegenüberLiegenden Stellen der Sammelleitung.In the known devices of this type have Mantle the task supplied to them via the support tubes To release compressed air in finely distributed form into the water · The fact that these coats from Consist of rubber or rubber-like plastics, has the advantage that the in the jacket, Open slot-like perforations only if they are under compressed air from the inside or if they are closed when they are not in use and no compressed air is to be discharged into the water. The known Devices of this type are very expensive because the jacket is in short lengths are drawn on slightly longer support tubes, which in turn are like a Christmas tree to a collecting line are connected. So the individual support pipes branch off from this collecting line, namely mostly at opposite points of the collecting line.
Diese Vorrichtungen sind somit nicht nur in ihrem Aufbau, sondern auch in ihrer Herstellung und ihrer Verlegung verbesserulgebedürftig.These devices are thus not only in their construction, but also in their manufacture and their Relocation in need of improvement.
Der Erfindung liegt im wesentlichen die Aufgabe zugrunde9 die günstige Wirkungsweise der obigen Vorrichtungen zu erialten, jedoch deren Herstellung und deren Verlegung zu vereinfachen, wobei auch eine schnellere Anpassung an sich ändernde Betriebsbedingungen und eine noch intensivere Belüftung angestrebt werden.The invention is essentially based on the object 9 to establish the favorable mode of operation of the above devices, but to simplify their manufacture and their installation, with a faster adaptation to changing operating conditions and an even more intensive ventilation being sought.
Zur Lösung dieser Aufgabe gehen erfindungsgemäss die Stützrohre benachbarter Mantel einstückig ineinander über, und der so gebildeten Stützleitung wir die Luft an einem oder an beiden Enden für alle hierauf befindlichen Mantel zugeführt.To solve this problem go according to the invention Support tubes of adjacent jacket integrally into one another, and the support line formed in this way we the air at one or both ends for all on it Coat fed.
Es ist somit eine vergleichsweise lange Stützleitung vorgesäien, auf die der Reihe nach die einzelnen Mantel aufgezogen sind, die ihrerseits an ihren beiden Enden durch Schellen od. dgl. abgebunden, also abgedichtet sind, um so das der langen Stützleitung zugeführte Luftvolumen den einzelnen Mäntel zuführen zu können. Dabei können für ein Wasser- bzw. Abwasserbecken natürlich zwei oder mehrere Sti/tzleitungen verwendet werden, jedoch sind in jedem Fallo auf einer Stützleitung mehrere Mäntel, also di© eigentlichen Luftverteiler angeordnet.A comparatively long support line is therefore provided, on which the individual cloaks are pulled up one after the other, which in turn at both ends Od by clamps. Like. Tied, so sealed, so that the long support line fed To be able to supply air volume to the individual jackets. Of course, two or more support lines can be used for a water or waste water basin, however, in each fallo there are several on a support line Coats, i.e. the actual air distributor arranged.
Die Erfindung eröffnet auch die Möglichkeit, biegsame Stützleitungen zu verwenden, um sie so zusammen mit den Mänteln besonders leicht lagern, transportieren, insbThe invention also opens up the possibility of using flexible support lines to so together with store and transport the coats particularly easily, esp

Ein biegsam ausgeführtes Stützrohr hat weiterhin den grossen Vorteil, dass die Vorrichtung in Biegungen, Schlangen od. dgl. verlegt werden kann. Diese Ausbildung der Vorrichtung ermöglicht zudem eine weitgehende, besonders gute Anpassung an die örtlichen Gegebenheiten, insb. an die Grundrissform des Beckens, in deim sich das Wasser befindet, Runde oder ovale Becken können daher besonders gut belüftet werden.but to be able to lay in a simple way · G ^ f 3. can The S; ützlinien be arranged on drums or rollers in order to lay these elements to be able to withdraw. A flexible support tube also has the great advantage that the device in bends, snakes or the like. Can be laid. This design of the device also enables a extensive, particularly good adaptation to the local conditions, especially to the shape of the basin, where the water is located, round or oval pools can therefore be particularly well ventilated.

über einen Druckluftanschluss 1 wird die Luft einem T-förmigen Verbindungststück 2 zugeführt. Von dort aus gelangt sie zu einem Polyäthylenrohr 3, das druckdicht mittels Schelle 4 mit dem Verbindungsstück verbunden ist und einen Durchmesser von 4 - 8 cm haben kann bei einer Wandstärke von 3-6 mm, und zwar in der Weise, dass dieses Rohr noch ausreichend biegsam ist,„,, andererseits aber unter dem Wasserdruck noch seine runde bzw. ggfs. ovale Querschnittsform beibehält. Das Rohr 2 ist über seine Länge hinweg an gegenüberliegenden Stellen mit Reihen von radialen Schlitzen 5 ausgestattet. Eng anliegend ggfs. mit einer geringen Vorspannung ist dieses Rohr von einem Mantel 6 umschlossen, der an seinen Enden gegenüber dem 1olyäthylenrohr 3 durch eine Scheue 7 abgebunden ist, insoweit also im Endbereich druckluftfest mit der Aussenfläche dieses Rohres verbunden ist. Die Mantel 6 - in einer Vielzahl vorhanden - sind über die Länf β des Polyäthylenrohres 3 verteilt angeordnet und überdecken Je nur die paarweise zusammengehörigen Reihen der Schlitze 5.The air is fed to a T-shaped connecting piece 2 via a compressed air connection 1. From there it reaches a polyethylene pipe 3, which is connected to the connector in a pressure-tight manner by means of a clamp 4 and can have a diameter of 4-8 cm with a wall thickness of 3-6 mm, in such a way that this pipe is still sufficient is flexible, but on the other hand still retains its round or possibly oval cross-sectional shape under the water pressure. The tube 2 is provided with rows of radial slots 5 at opposite points along its length. Closely fitting, possibly with a slight bias, this tube is enclosed by a jacket 6, which is tied off at its ends opposite the 1 olyäthylenrohr 3 by a bar 7, so as far as the end area is connected to the outer surface of this tube in a compressed air-tight manner. The sheaths 6 - available in a large number - are arranged distributed over the length β of the polyethylene tube 3 and only cover the rows of slots 5 that belong together in pairs.
Die Mäntel 6 haben radiale Sch Litze 8 in grosser Anzahl z.B. mit einer Länge von 0.5 Em einem Abstand von 1.5 mm, wobei die Schlitzreihen wiederum einen Abstand, von Λ - 2 mm aufweisen. Es versteht sich, dass die Schlitze 8 nur in dem Bereich zwischen den Schellen 7» also im Bereich der Schlitze 5 vorgesehen sind. Darüber hinaus sind auch im Bereich der unmittelbar den Schlitzen 5 zugekehrten Abschnitte S keine Schlitza 8 vorgesehen· Diese nicht geschlitzten Wandungsabschnitte der Mäntel 6 überdecken die Schlitze 5, sie heben sich allerdings ab, wenn die Druckluft eingeführt wird, um sie den nebenan liegenden Schlitzen 8 zuzuführen. Diese Überdeckung der Schlitze 5 ha>; den Vorteil, dass im Bereich der breiteren Schlitze 5 geringfügige Verformungen der Mäntel 6 eintreten können, ohne befürchten zu müssen,The sheaths 6 have a large number of radial strands 8, for example with a length of 0.5 Em and a distance of 1.5 mm, the rows of slots in turn having a distance of Λ -2 mm. It goes without saying that the slots 8 are only provided in the area between the clamps 7 », ie in the area of the slots 5. In addition, no slots 8 are provided in the area of the sections S directly facing the slots 5. These non-slotted wall sections of the jackets 6 cover the slots 5, but they stand out when the compressed air is introduced around them to the adjacent slots 8 to feed. This covering of the slots 5 ha>; the advantage that in the area of the wider slots 5 slight deformations of the sheaths 6 can occur without having to fear that

Fremdstoffe aufnehmen und den Luftaustritt in feinstverteilter Form stören oder gar unterbinden·that there are slots δ when the polyethylene pipe is not pressurized (without pressure) 3 slots 8 in the jacket 6 cannot close. Non-closing slots 8 could absorb foreign substances and the air leakage interfere or even prevent in finely divided form
Die so ausgestatteten Polyäthylenrohre 3 mit den hierauf aufgereihten Mänteln 6 können gemäss Fig. 1 innerhalb des Abwasserbeckens mit Rändern 9» Seitenwänden 1o und Bodenfläche 11 verlegt sein. So können Ringleitungen 12 vorgesehen sein, denen zwei Druckluftanschlüsse 1 zugeordnet sein können. Jedoch kann auch eine Verlegung nach Art von Serpentinen 13 erfolgen, wobei jedoch auch hier auf die Biegsamkeit des Polyäthylenrohres 3 Rücksicht genommen werden muss. Dieses Rohr kann also gekrümmt verlegt werden; jedoch müssen Knickungen vermieden werden. Wie im oberen Teil der Fig.1 aufgezeigt, können die als Stützrohre dienenden Polyäthylenrohre 3 parallel zu einer Kante 9 verlegt werden und dabei an ihren Enden am Beckenrand verankert sein. Dabei kann ein Druckluftanschluss 1 an einem Ende ausreichend sein.The so equipped polyethylene pipes 3 with the on it lined up jackets 6 can according to FIG. 1 within the wastewater basin with edges 9 »side walls 1o and Floor area 11 be laid. Thus, ring lines 12 can be provided to which two compressed air connections 1 are assigned could be. However, laying in the manner of serpentines 13 can also take place, although here too the flexibility of the polyethylene pipe 3 must be taken into account. This pipe can therefore be curved be relocated; however, kinks must be avoided. As shown in the upper part of Fig.1, can serving as support pipes 3 polyethylene pipes are laid parallel to an edge 9 and thereby at their ends be anchored at the edge of the pool. A compressed air connection 1 at one end can be sufficient here.

Wichtig ist somit, dass den Mänteln 6 nicht $e ein etwa ihrer Länge entsprechendes Stützrohr, sondern einer Vielzahl hintereinander angeordneten Mänteln 6 nur ein durchgehendes Stütz-rohr zugeordnet ist, das vorzugsweise biegsam ausget .ldet ist. und nach Möglichkeit an Ort und Stelle von Trommeln od. dgl. abge zogen werden kann, wenn die Vorrichtung montiert werden soll. It is important therefore that the casings 6 are not a $ e about its length corresponding to the supporting tube, but a plurality of serially-arranged sheaths 6 only is assigned to a through support tube, which is preferably flexible .ldet ausget. and if possible on the spot of drums or the like. abge can be withdrawn when the device is to be mounted .
Es liegt auch im Rahmen der Erfindung, das Polyäthylenrohr 3 stellenweise z.B an Stein3n, an denen besonders kleine Biegradien verlangt werden, nicht zu perfor ieren und dort auf die Anbringung vor Mänteln 6 zu verzichten, obwohl diese wegen ihrer Düni.wandigkeit und ihrer hohen elastischen Verformbarkeit auch kleinen Radien keine Schwierigkeiten bereiten.It is also within the scope of the invention not to perforate the polyethylene pipe 3 in places, for example on stones where particularly small bending gradients are required, and to dispense with the attachment there in front of jackets 6, although these are due to their thin walls and their high elasticity Deformability, even with small radii, poses no difficulties.
Es ist weiterhin möglich, den aus Gummi oder dergl. bestehenden Mantel 6 nicht nur mit zwei, sondern auch mit drei oder mehrerer Abbindungen in Form von Schellen 7 odar dergl. zu versehen, ur -;o eine mehrfache Unterteilung eines Mantelabschnittes vorzusehen. Damgemäß kann sich auch ein Mantel abschnitt über eine gröTere Länge einer 5tützle;tung erstrecken. Es versteht sich riaboi x π*:-. man im Regelfalle für die Abbindungen gleiche Abstand? vrvervioi.. Diese Kehrfach-Unte-teilung hat b;i längeren Mänteln r, ric-n Vorteil, daß eine gleichmäßige Durchlüftung über die Mantel längo hinwe-;: sichergestellt ist.It is also possible to provide the jacket 6 made of rubber or the like not only with two, but also with three or more ties in the form of clamps 7 or the like, and to provide a multiple subdivision of a jacket section. Accordingly, a jacket section can also extend over a greater length of a 5tützle ; extension. It goes without saying riaboi x π *: -. do you usually have the same distance for the ties? vrvervioi ..
