Description
WasserbelüftungsrohrWater ventilation pipe
Die Erfindung betrifft ein Wasserbelüftungsrohr, ins.The invention relates to a water ventilation pipe, ins.
für die Trink- und Abwasserbelüftün# mit einem steifen Stützrohr und einem darauf angeordneten Schlauch aus Gummi od. dgl., der eine Vielzahl kleiner Schlitze zum Durchtritt der Luft aufweist und an seinen Enden durch Schellen od. dgl. auf dem Stützrohr befestigt ist. Vorzugsweise ist dabei das Stützrohr an seiner am weitesten unten liegenden Stelle mit einer Durchbrechung ggfs. in Form einer Reihe von Langlöchern versehen, von der aus die Druckluft unter den Schlauch und von dort aus über viele Schlitze in das Wasser gelangen kann.for drinking and wastewater aeration # with a stiff support tube and a hose made of rubber od Has slots for the passage of air and od at its ends by clamps. Like. Is attached to the support tube. The support tube is preferably on its furthest down the point with an opening, possibly in the form of a Series of elongated holes from which the compressed air flows under the hose and from there it can get into the water through many slits.
Wichtig ist dabei, dass kleine, regelmässige Luftblasen entstehen, die insg. ein gleichmässiges Blasenbild ergeben sollen. Zugleich soll der Druckverlust im Rohr gering sein, um so möglichst wenig Energieverluste zum Ausdrücken der Luft hinnehmen zu müssen.It is important that small, regular air bubbles are created, which should result in a uniform bubble pattern. At the same time, the pressure loss should be small in the pipe, so as to minimize energy losses to express the air to have to accept.
Verständlicherweise spielen dabei die Abmessungen der Schlitze, deren Abstand untereinander und zwischen den Schlitzreihen eine grosse Rolle.Understandably, the dimensions of the slots play a role The distance between one another and between the rows of slots plays a major role.
Es wurde gefunden, dass diese Forderungen am besten erfüllt werden können, wenn im wesentlichen folgende Bedingungen erfüllt sind a. Die Schlitzlänge soll etwa o,75 - 1,5 mm betragen, innerhalb der Schlitzreihen soll der gegenseitige Abstand der Schlitze etwa 1,5 - 2,25 mm sein.It has been found that these requirements are best met can if essentially following Conditions are met a. The length of the slot should be around 0.75 - 1.5 mm, within the rows of slots the mutual distance between the slots should be about 1.5 - 2.25 mm.
b. Der gegenseitige Abstand der Schlitzreihen soll etwa 2,o - 2,75 mm sein.b. The mutual distance between the rows of slots should be about 2.o - 2.75 be mm.
c. Unter diesen Voraussetzungen soll angestrebt werden, auf einer wirksamen Schlauchlänge von etwa 500 mm eine gesamte Schlitzlänge von etwa 8 - 12 m unterzubringen.c. Under these conditions the aim should be on one effective hose length of about 500 mm a total slot length of about 8-12 m accommodate.
Schliesslich ist es vorteilhaft, wenn bei im Stützrohr unten befindlichen Durchbrechungen im Schlauch die Schlitze im unteren Teil des Schlauches ( im Querschnitt gesehen ) über eine Umfangslänge von 1/4 - 1/2 des Schlauchumfanges die Schlitze generell fehlen.Finally, it is advantageous if at the bottom of the support tube Openings in the hose, the slots in the lower part of the hose (in cross-section seen) over a circumferential length of 1/4 - 1/2 of the hose circumference the slots generally absent.
Hierdurch wird nämlich erreicht, dass die einzelnen Luftblasen unabhängig voneinander abströmen bzw. den Schlauch verlassen können, ohne also andere Luftblasen mitzunehmen und gar mit ihnen grössere Luftblasen zu bilden.In this way it is achieved that the individual air bubbles are independent can flow away from each other or leave the hose without other air bubbles take with you and even form larger air bubbles with them.
Weitere Einzelheiten der Erfindung werden anhand der Zeichnung erläutert, in der ein Ausführungsbeispiel der Erfindung dargestellt ist.Further details of the invention are explained with reference to the drawing, in which an embodiment of the invention is shown.
Es zeigen Fig. 1 ein Druckluftwasserbelüftungsrohr in der Seitenansicht, Fig. 2 das Rohr gemäss Fig. 1 im Querschnitt ( nur teilweise schraffiert ), Fig. 3 eine Draufsicht auf den den Mantel des Rohres bildenden Schlauch, als Teildraufsicht in vergrössertem Masstab und Fig. 4 einen senkrechten Schnitt durch den Schlauchabschnitt gemäss Fig. 3.1 shows a compressed air water ventilation pipe in a side view, Fig. 2 the tube according to FIG. 1 in cross section (only partially hatched), FIG. 3 a Top view of the hose forming the jacket of the pipe, as a partial top view on an enlarged scale and FIG. 4 shows a vertical section through the hose section according to Fig. 3.
Das Stützrohr 1 besteht aus einem hart eingestellten Kunststoff und kann beliebig gehaltert, z.B. auch mit anderen Rohren vereinigt sein. Es hat an der tiefsten Stelle eine Durchbrechung 2, die von einem Langloch gebildet wird, das sich in Längsrichtung des Rohres erstreckt und mit anderen eine Reihe bildet.The support tube 1 consists of a hard plastic and can be held in any position, e.g. combined with other pipes. It's on the deepest point an opening 2, which is formed by an elongated hole, which extends in the longitudinal direction of the pipe and forms a row with others.
Das Stützrohr 1 wird von einem Schlauch 3 aus einem weich eingestellten Gummi mit einer Härte von etwa 4o - 65 Shore A eng umschlossen, der an seinen Enden durch Schellen 4 fixiert, also abgedichtet und gegen Verschieben gesichert ist.The support tube 1 is set by a hose 3 from a soft Rubber with a hardness of about 40 - 65 Shore A is tightly enclosed at its ends fixed by clamps 4, that is, sealed and secured against displacement.
In den Schlauch 3 sind viele Schlitze 5 ohne Materialwegnahme eingestanzt, durch die die Druckluft möglichst gleichmässig in feinen Perlen entweichen soll. Vgl. die Pfeile 6 und den Pfeil 7 über die Zuleitung der Druckluft zum Stützrohr 1 und die Pfeile 8, nach denen die Druckluft das Stützrohr 1 verlässt und zwischen Stützrohr 1 und Schlauch 3 gelangt zum Ableiten durch die sich unter dem Innendruck aufweitenden Schlitze 5, die sich jedoch nach Abstellen der Druckluft wieder schliessen.Many slots 5 are punched into the tube 3 without removing any material, through which the compressed air should escape as evenly as possible in fine pearls. Compare the arrows 6 and the arrow 7 via the supply line for the compressed air to the support tube 1 and the arrows 8, according to which the compressed air leaves the support tube 1 and between Support tube 1 and hose 3 are diverted through the under the internal pressure widening slots 5, which, however, close again after the compressed air has been turned off.
Geht man von Rohrdurchmessern von etwa 50 - 120 mm aus, so sdlen folgende Werte benutzt werden Die Schlitzlänge soll etwa 1 mm und der gegenseitige Abstand der Schlitze 5 einer Reihe soll etwa 1,9 mm sein. Der gegenseitige Abstand der Schlitzreihen beträgt etwa 2,4 mm.Assuming pipe diameters of around 50 - 120 mm, the following should be used Values are used The slot length should be about 1 mm and the mutual distance the slots 5 of a row should be about 1.9 mm. The mutual distance between the rows of slots is about 2.4 mm.
Weiterhin soll in Bezug auf die Durchbrechung 2 im unteren Teil des Schlauches 3 eine schlitzfreie Zone vorgesehen sein, deren Mitte der Durchbrechung 2 gegenüberliegen soll. Die Umfangserstreckung dieser Zone soll etwa 1/3 des Schlauchumfanges sein.Furthermore, in relation to the opening 2 in the lower part of the Hose 3 a slot-free zone can be provided, the center of which is the opening 2 should be opposite. The circumference of this zone should be about 1/3 of the circumference of the hose be.
Erwähnt sei noch, dass die Wandstärke des Schlauches 3 etwa 1,5 - 2,5 mm beträgt.It should also be mentioned that the wall thickness of the tube 3 is about 1.5 - Is 2.5 mm.
