Description

Vorrichtung zum Ablenken eines Gas-oder Flüssigkeitsstrahles Die Erfindung betrifft eine Vorrichtung zum Ablenken eines aus einem Kanal austretenden Gas- oder Flüssigkeitsstrahles mit Hilfe von an die Kanalwand anschließenden, zum Strahl konvex gekrümmten Wandfortsetzungen unter Ausnutzung des sogenannten Coanda-Effektes.Device for deflecting a gas or liquid jet The invention relates to a device for deflecting a gas or gas emerging from a channel Fluid jet with the help of connecting to the channel wall, convex to the jet curved wall continuations using the so-called Coanda effect.

Es sind bereits Verfahren und Vorrichtungen bekanntgeworden, die alle den Zweck haben, unter Ausnutzung des sogenannten Coanda-Effektes einem Gas-oder Flüssigkeitsstrahl eine andere Richtung zu geben, als er ursprünglich hatte. Ferner hat man diesen Effekt in Kombination mit anderen Maßnahmen schon bei Verfahren zum Hin- und Herschwenken eines Gas-oder Flüssigkeitsstrahles, also zur Erzielung von periodisch oder nicht periodisch sich wiederholenden Richtungsänderungen angewendet, indem man beispielsweise nach einem älteren Patent im Zuströmkanal vorgesehene Ablenkorgane, die selbst nicht Förderorgane sind, sich so hin- und herbewegen läßt, daß der Gas- oder Flüssigkeitsstrahl in einem an den Kanal anschließenden Raum seine Bahn regelmäßig verlagert. There are already methods and devices known that all have the purpose of making use of the so-called Coanda effect a gas or To give a different direction to the liquid jet than it originally had. Further one has this effect in combination with other measures already in procedures for Pivoting a jet of gas or liquid back and forth, ie to achieve periodically or non-periodically repeated changes of direction are used, by, for example, according to an older patent provided deflection elements in the inflow channel, which are not conveying organs themselves, can be moved to and fro in such a way that the gas or a liquid jet in a space adjoining the channel moves its path regularly relocated.

Während nun durch die eben erwähnten Maßnahmen der Gas- oder Flüssigkeitsstrahl noch vor seinem Austritt aus einem Zuströmkanal im Sinne eines ständigen Richtungswechsels außerhalb des Kanals beeinflußt werden soll, besteht die Erfindung darin, daß die Wandfortsetzungenldes Zuströmkanals als an gegenüberli egenden Seiten der rechteckigen Austrittsöffnung des Kanals angeordnete gewöLbte Bleche ausgebildet sind, die in gegenseitigem Wechsel periodisch an den Rand des Strahles angelegt und von diesem wieder entfernt werden können, wodurch der Strahl in einem an den Kanal anschließenden Raum periodisch hin-und hergeschwenkt wird. While now by the measures just mentioned the gas or liquid jet even before it emerges from an inflow channel in the sense of a constant change of direction to be influenced outside the channel, the invention is that the Wall continuations of the inflow channel than on opposite sides of the rectangular one Outlet opening of the channel arranged curved metal sheets are formed, which in mutual alternation periodically applied to the edge of the beam and from this can be removed again, whereby the beam in a subsequent to the channel Space is periodically swung back and forth.

Der Vorteil dieser Vorrichtung gegenüber den bekannten Maßnahmen besteht darin, daß die Strömung im Kanal ungestört bleibt, insbesondere nicht durch allfällige Einbauten im Querschnitt verändert wird, und daß die Vorrichtung sich leicht auch nachträglich einbauen läßt, beispielsweise in Trockner, die überhaupt ein bevorzugtes Anwendungsgebiet für solche Vorrichtungen darstellen. The advantage of this device over the known measures is that the flow in the channel remains undisturbed, especially not through any internals is changed in cross-section, and that the device itself can also be easily installed subsequently, for example in a dryer, at all represent a preferred field of application for such devices.

In Ausgestaltung der Erfindung sind die gewölbten Bleche mit ihren von der Zuströmseite entfernten Enden an außerhalb des Strahles befindlichen Drehachsen schwenkbar befestigt und in Abhängigkeit voneinander bewegbar. Sie können aber auch starr miteinander verbunden und gemeinsam quer zur Achse des Kanals verschiebbar sein. In an embodiment of the invention, the curved sheets with their ends remote from the inflow side on axes of rotation located outside the jet pivotally mounted and movable as a function of one another. But you can too rigidly connected to one another and displaceable together transversely to the axis of the channel be.

Eine Anpassung der erfindungsgemäßen Vorrichtung an die Strömungsgeschwindigkeit und auch an andere Faktoren, wie die Zähigkeit des Gases oder der Flüssigkeit, welche die Ablösung der Strömung von den gewölbten Blechen beeinflussen, ist dadurch möglich, daß man den Abstand der Drehachsen bzw. den Abstand der starr miteinander verbundenen Bleche veränderbar macht. An adaptation of the device according to the invention to the flow rate and also to other factors, such as the viscosity of the gas or the liquid, which the detachment of the flow of affect the curved sheet metal, it is possible that the distance between the axes of rotation or the distance between the rigidly interconnected Makes sheet metal changeable.

Um ein rasches Ablösen des Gas- oder Flüssigkeitsstrahles von den gewölbten Blechen bei Richtungswechsel zu erreichen, sind an der Austrittsöffnung des Kanals kurze, gerade Wandfortsetzungen vorgesehen, die mit den Eintrittskanten der Bleche Luftansaugeschlitze begrenzen, welche durch die Bewegung der Bleche abwechselnd geöffnet und verschlossen werden. In order to quickly detach the gas or liquid jet from the Arched metal sheets to be reached when changing direction are at the outlet opening of the canal provided short, straight wall continuations that correspond to the leading edges of the sheets limit air intake slots, which alternate due to the movement of the sheets opened and closed.

Die Erfindung wird an Hand einer Zeichnung, deren Fig. 1 und 2 jeweils einen anderen Strömungszustand bei demselben Ausführungsbeispiel der Vorrichtung zeigen, näher erläutert. The invention is based on a drawing, FIGS. 1 and 2, respectively another flow condition in the same embodiment of the device show, explained in more detail.

An der Austrittsöffnung 4 des Zuströmkanals sind kurze Wandfortsetzungen 8 und 9 vorgesehen, hinter denen in Strömungsrichtung zwei spiegelbildlich gleiche gewölbte Bleche 2 und 3 angeordnet sind. Diese Bleche sind um Achsen 6 bzw. 7 in Abhängigkeit voneinander schwenkbar. There are short wall extensions at the outlet opening 4 of the inflow channel 8 and 9 are provided, behind which two mirror images of the same in the flow direction curved sheets 2 and 3 are arranged. These sheets are about axes 6 and 7 in Can be pivoted depending on each other.

In Fig. 1 ist die gegenseitige Lage der gewölbten Bleche 2 und 3 derart, daß sie an dem Strahl 1, der aus der Austrittsöffnung 4 ausströmt, nicht anliegen. The mutual position of the curved metal sheets 2 and 3 is shown in FIG. 1 in such a way that they are not on the jet 1 which flows out of the outlet opening 4 issue.

In diesem Fall sind die Luftansaugeschlitze 12 und 13, die jeweils durch die kurzen Wandfortsetzungen 8 und 9 sowie die Eintrittskanten 10 und 11 begrenzt werden, offen.In this case, the air intake slots 12 and 13, respectively limited by the short wall continuations 8 and 9 and the leading edges 10 and 11 be open.

Sobald nun die Bleche 2 und 3 die in Fig. 2 gezeigte Lage annehmen, wobei also das Blech 2 sich an den Rand des Strahles 1 anlegt, erfährt dieser in der Zeichenebene eine Richtungsänderung nach links. In diesem Fall ist nur der Luftansaugeschlitz 13 geöffnet, der andere dagegen geschlossen. As soon as the sheets 2 and 3 assume the position shown in Fig. 2, so that the sheet 2 rests on the edge of the beam 1, this experiences in the drawing plane a change of direction to the left. In this case there is only the air intake slot 13 open, the other closed.

Erfolgt die Bewegung der gewölbten Bleche 2 und 3 in entgegengesetzter Richtung, also in der Zeichnung nach links, so öffnet sich der Luftansangeschlitz 12, und die durch ihn einströmende Luft trennt sogleich den Strahl 1 von dem gewölbten Blech 2, so daß der in Fig. 1 dargestellte Zustand wiederhergestellt ist. The movement of the curved sheets 2 and 3 takes place in opposite directions Direction, i.e. to the left in the drawing, the air inlet slot opens 12, and the air flowing in through it immediately separates the jet 1 from the curved one Sheet 2, so that the state shown in Fig. 1 is restored.

Bei weiterem Fortgang der Bewegung nach links lehnt sich dann sinngemäß :das Blech 3 an den Strahl 1 an, so daß dieser nach rechts abgelenkt wird.If the movement continues to the left, then leans accordingly : the sheet 3 to the beam 1, so that this is deflected to the right.

Der Abstand der Drehachsen 6 und 7 kann veränderbar sein, um die Vorrichtung den jeweiligen Betriebsverhältnissen anzupassen. The distance between the axes of rotation 6 and 7 can be changed to the Adapt the device to the respective operating conditions.

Die Vorrichtung nach der Erfindung hat Bedeutung beispielsweise beim Belüften von Räumen oder beim Behandeln von in einem Raum ausgebreitetem Gut mit Gas oder Flüssigkeiten, wozu auch das Trocknen zu rechnen ist. Ferner läßt sich die Vorrichtung beim Waschen von verunreinigten Gasen mit Vorteil anwenden. The device according to the invention is important for example when Ventilating rooms or when treating goods spread out in a room Gas or liquids, including drying. Furthermore can use the device with advantage when washing contaminated gases.
