Abstract

Single or multi-armed aeration pipe with horizontal alignment has vertical deflector plates rising vertically from the pipes. This tapers towards the central feed pipe terminating in a region above the main aeration zone. This inclined edge is rounded. The plate is made either from a rigid material, a cloth, a sheet or similar type of construction. The deflector can be held rigid by mounting wires. Each arm of an aerater has such a deflector plate. For preventing the accumulation of suspended solids or fibres on aeration pipe which thus would reduce their effectiveness.

Description

Pezeichnung: Vorrichtung zur Verhinderung der Ablagerung von Schwebeteilen an Rohrbelüftern Bei Belüftungsvorrichtungen, gleich welcher Bauart, tritt oft das Problem auf, zu verhindern, da3 die durch vorgeordnete Rechen oder sonstige Trennvorrichtungen nicht zurückhaltbaren Qchwebestoffe, z. P. in Form von Gewebeteilen, die Belüftungsaustrittsstellen zusetzen oder zumindest so beeinträchtigen, daß ein feinblasiges, die Sauerstoffzufuhr förderndes Belüften nicht mehr in ausreichendem flaa;?e m.cglich ist. Diesen Magnel versucht die vorliegerde Erfindung in Anwendung für Rohrbelüfter, gleich welcher Bauart, abzuhelfen.Drawing: Device to prevent the deposition of suspended particles on pipe aerators This often occurs with ventilation devices of any type There is a problem in preventing the damage caused by upstream rakes or other separating devices non-retainable suspended matter, e.g. P. in the form of pieces of tissue, the ventilation exit points add to or at least affect so that a fine-bubble, the oxygen supply promoting ventilation is no longer possible in sufficient flaa;? e is possible. This Magnel tries the present invention in application for pipe aerators, whatever Bauart to remedy.

Sie löst die Aufgabe dadurch, daß, wie im Patentanspruch 1 aufgefährt, die die Luftaustrittstellen aufweisenden Belüftungsrohrteile mit senkrecht nach oben gerichteten Ableitfl chen ausgestattet sind.It solves the problem in that, as mentioned in claim 1, the ventilation pipe parts having the air outlet points vertically afterwards are equipped with discharge surfaces facing upwards.

Damit wird die auSsteigende Luft so geleitet, daß sie in ihren Bereich gelangende Schwehestoffe nach oben führt und, wie iius der weiteren vorteilhaften Ausbildung der Erfindung zu ersehen, über eine schräg abfallende Gleitkante in einen außerhalb des Belüftungsrauines liegenden Bereich abgleiten läßt.This directs the rising air in such a way that it is in its area arriving suspended matter leads upwards and, like iius the further advantageous Training of the invention can be seen on a sloping sliding edge in one outside of the ventilation roughness area can slide.

Ein mit zwei Zeichnungen belegtes Ausführungsbeispiel mag dies verdeutlichen.An exemplary embodiment with two drawings may illustrate this.

Die Zeichnungen, Fig. 1 und Fig. 2, zeigen aus zwei Betrachtungsrichtungen, unter Fortlassung aller für die Erfindung unwesentlichen Baueinheiten, den prinzipiellen Aufbau des den Luftaustritt gebenden Teiles eines zweiarmigen Belüfters.The drawings, FIGS. 1 and 2, show from two viewing directions, omitting all the structural units that are insignificant for the invention, the basic ones Structure of the air outlet giving part of a two-armed aerator.

Seine Bestandteile sind: ein senkrechtes Luftzufuhrrohr A, Ein Verbindungsstück B, zwei waagrechte Belüftungsrohre C 1 und C 2 mit den Luftaustritt stellen P, sowie schließlich die jedem Belüftungsarm zugeordneten Ableitfl chen F 1 und F 2. Aus der die Schmalkante der einzelnen Ableitfl chen zeigenden Fig. 2 ist die Rundung G der chargen Gleitkantenfläche zu erkennen.Its components are: a vertical air supply pipe A, a connector B, two horizontal ventilation pipes C 1 and C 2 with the air outlet represent P, as well as finally the discharge surfaces F 1 and F 2 assigned to each ventilation arm Fig. 2 showing the narrow edge of the individual deflecting surfaces is the curve G of the batch sliding edge surface can be recognized.

Die über das Luftzufuhrrohr A einströmende Luft ist mit L, die die Belüftungsrohre verlassende Luft mit E bezeichnet. Gelangt irgendein Schwebestoff in den Bereich der abströmenden Luft E, dann Nfrd er durch die Führung der Ableitfläche F 1 hochgetrieben und in einen Bereich außerhalb der Belüftungszone befördert.The air flowing in via the air supply pipe A is labeled L, which is the Air leaving ventilation pipes is designated with E. Any suspended matter gets into it in the area of the outflowing air E, then through the guidance of the deflection surface F 1 is driven up and transported to an area outside the ventilation zone.

Sollte er dabei auf die Ableitfläche zurückfallen, dann wird er über ihre schräge und zudem gerundete Gleitkante G abgewiesen.Should it fall back onto the deflection surface, then it will over their inclined and also rounded sliding edge G rejected.

Selbstver£-tWndlich sind bei der Ausbildung der Ableitfläche auch sonst scharfe und eckige stellen vermieden, um an keiner Stelle ein Mängenbleiben der ungewünschten Schwebestoffe möglich zu machen.It goes without saying that they are also delicate in the formation of the discharge surface Otherwise sharp and angular spots are avoided so as not to be deficient at any point to make the undesired suspended matter possible.

Das Naterial, aus dem die Ableitfläche F 1 gebildet ist, kann, der Beanspruchung angepasst, entweder ein selbsttragendes Blech, ein selbsttragender Kunststoff, eine auf einem Draht- oder Rohrrahmen aufgespannte Folie oder etwas diesem Gleichsetzbares sein.The material from which the deflecting surface F 1 is formed can, the Load adapted, either a self-supporting sheet metal, a self-supporting one Plastic, a film stretched on a wire or pipe frame or something to be equated with this.
