Abstract

This pipe, intended in particular for waste water, has, on the outside, a hose of rubber or the like, which is finely perforated by slits which open when compressed air is supplied and which close when the compressed air supply is terminated. This hose is intended to maintain its elastic deformability for years. Therefore it is given an outer layer, which in comparison to the layers beneath contains fewer organic substances and/or a larger amount of substances to combat microorganisms.

Description

Belüftungsvorrichtung für WasserAerator for water

Die Erfindung betrifft eine Belüftungsvorrichtung für Wasser, Insb. Abwasser mit einem aus Gummi od. dgl.The invention relates to an aeration device for water, esp. Waste water with a rubber or the like.

bestehenden Schlauch, der in grosser Anzahl mit feinen Schlitzen in der Weise versehen ist, dass sich diese Schlitze unter der Wirkung der von innen zugeführten Druckluft öffnen und sich nach der Druckluftzufuhr wieder schliessen.existing hose, which in large numbers with fine slits in it is so provided that these slits are under the action of from within open the supplied compressed air and close again after the compressed air supply.

Diese Vorrichtungen haben den Vorteil, dass Wasser nicht in das Belüftungssystem eindringen kann, wenn keine Druckluft zugeführt wird. Unter diesen Voraussetæungen sind die Schlitze in dem erwähnten Schlauch geschlossen.These devices have the advantage that water does not enter the ventilation system can penetrate if no compressed air is supplied. Under these conditions the slots in the mentioned tube are closed.

Auf Dauer ist aber nur dann eine ordnungsgemässe Wirkun!.rrsweise des Schlauches möglich, wenn der schlauch nicht verhärtet, seine elastische Verform' arkeit also sichergestellt bleibt.In the long run, however, it will only work properly of the hose possible if the hose does not harden, its elastic deformation ' aridity remains guaranteed.

Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, die oben erwähnten Belüftungsvorrichtungen so zu verbessern, dass die Funktion der sich selbsttätig schliessenden Schlite zum Zuführen der Druckluft für einen ver-Fleichsweise langen Zeitraum erhalten bleibt.The invention is essentially based on the object of the above mentioned ventilation devices to improve the function of itself Closing slide for supplying the compressed air for a long time Period is retained.

Zur Lösung dieser Aufgabe ist erfindungsgemäss der Schlauch mit einer Aussenschicht versehen, die im Vergleich zu den darunterliegenden Schichten wesentlich weniger organische Substanzen und/oder eine grössere Menge von Substanzen gegen Mikroorganismen aufweist, Die Aussenschicht kann dabei ein Anstrich sein, also lackartig aufgetragen und vorhanden sein; es ist aber auch möglich, schon bei der Schlauchherstellung eine Aussenschicht z.B. beim Spritzen des Schlauches vorzusehen.To solve this problem, the hose is according to the invention with a Provided outer layer, which is essential compared to the underlying layers fewer organic substances and / or a larger amount of substances against Has microorganisms, the outer layer can be a paint, i.e. lacquer-like applied and present; but it is also possible during the manufacture of the hose to provide an outer layer e.g. when spraying the hose.

Dabei vers teht es sich, dass das Vorhandensein dieser Aussenschicht die Ventilwirkung nicht ausschlieszen soll, die dielgenannten Schlitze ausüben. Daher soll die Aussenschicht auch zumindest über eine gewisse elastische Verfornbarkeit verfügen. So ist es auch möglich, für die Aussenschicht Butylkautschuk cder Siliconkautschuk zu verwenden, während für die Innenschicht des Schlauches eine ggfs. weichere Gummiqualität z.B. auf der Basis von Naturkautschuk verwendbar ist.It turns out that the presence of this outer layer the valve effect is not intended to exclude the aforementioned slots. Therefore, the outer layer should also have at least a certain elastic deformability feature. It is also possible to use butyl rubber or silicone rubber for the outer layer to use, while a possibly softer rubber quality for the inner layer of the hose e.g. based on natural rubber can be used.

Ferner sind als Substanzen, die den Schlauch gegen die Wirkung von Bakterien schützen sollen, und dem Gummi od. dgl. #### beizumischen sind, folgende Stoffe geeignet Organische Quecksilberverbindungen ( Phenylmerciiriacetat ) Organische Kupfer- und Zinkverbindungen ( Zink--Pentachlorph nolat ) Organische Zinnverbindungen ( Tributylzinnacetat ) D imethyldithiocarbamat Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführun&sbeispiel dargestellt ist.Furthermore, as substances that counteract the action of the hose To protect bacteria, and the rubber or the like. #### are to be mixed with the following Suitable substances Organic mercury compounds (phenyl mercury acetate) Organic Copper and zinc compounds (zinc - pentachloroph nolate) Organic tin compounds (Tributyltin Acetate) Dimethyldithiocarbamate Further details of the invention are explained with reference to the drawing, in which an embodiment is shown is.

Es zeigen Fig. 1 einen Teillängsschnitt durch ein Belüftungsrohr für Abwasser und Fig. 2 eine Teildrauvsicht auf das Rohr gemäss Fig. 1.Show it Fig. 1 is a partial longitudinal section through a Ventilation pipe for waste water and FIG. 2 a partial plan view of the pipe according to FIG. 1.

Das Rohr weist aussen einen aus Gummi bestehenden schlauch 1 auf, der ein Geflecht 2 umschliesst, das ist das seinerseits ein Kunststoffrohr als hant eingestelltes Polyäthylenrohr 3 ausgebildet ist. Diesem Rohr wird die Druckluft in Richtung des Pfeiles x zugeführt.The pipe has a hose 1 made of rubber on the outside, which encloses a braid 2, that in turn is a plastic tube as a hand adjusted polyethylene pipe 3 is formed. The compressed air is sent to this pipe fed in the direction of arrow x.

Das Polyäthylenrohr 3 ist mit im Abstand voneiander angeordneten, unterschiedlich grossen Bohrungen 4 versehen, über die die Druckluft in das als Verteiler wirkende Geflecht 2 einströmt. Von hier aus kann die Druckluft unter den Schlauch1 gelangen, der mit einer Vielzahl von radialen Schlitzen 5 ausgestattet ist.The polyethylene tube 3 is arranged with spaced apart, different sized holes 4 provided through which the compressed air into the as Distributor acting braid 2 flows in. From here the compressed air can under the Hose 1, which is equipped with a large number of radial slots 5 is.

Diese sind unter normalen Bedingungen geschlossen.These are closed under normal conditions.

Wird jedoch Druckluft zugeführt, so öffnen sich die Schlitze 5, um so die Druckluft in das Abwasser zur biologischen Klärung abzuge';#en.However, if compressed air is supplied, the slots 5 open to so that the compressed air is discharged into the wastewater for biological clarification.

Wichtig ist nun, dass der Schlauch 1 aus einer Innenschicht 6 besteht, die hochelastisch aus Gummi bestehend für die Ventilwirkung der Schlitze Sorge trägt. Die Innenschicht 6 ist festhaftend mit einer Aussenschicht 7 ausgestattet, die ebenfalls über eine gewisse elastische Verformbarkeit verfügt, im übrigen aber Substanzen enthält oder aus diesen besteht, welche eine schädliche Bakterienbeeinflussung zur Verhärtung des ocillauches l praktisch ausschliesen, zumindest deren Wirkung über Jahre so herabsetzen, dass eine vergleichsweise lange Lebansdauer der Vorrichtung gewährleistet ist.It is now important that the hose 1 consists of an inner layer 6, which is made of highly elastic rubber and ensures the valve action of the slots. The inner layer 6 is provided with a firmly adhering outer layer 7, which is also has a certain elastic deformability, but otherwise substances contains or consists of these, which have a harmful effect on bacteria Hardening of the ocillauches l practically ruled out, at least their effect over Years so reduce that a comparatively long service life of the device is guaranteed.

Im alle der erwähnten Beimischungen sollte die Grundsubstanz elastisch verformbar sein, also aus Gummi od. dgl. bestehen.In all of the admixtures mentioned, the basic substance should be elastic Be deformable, i.e. made of rubber or the like.
