Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Förderung von Feststoffteilchen mit Hilfe einer Luftströmung, wobei der Luftstrom einem Kanal zugeführt wird, in den Feststoffteilchen wie z. B. Kohlestaub eingeleitet werden und der Kanal mit einem konusartigen Anschlußstück versehen ist.The invention relates to a device for the promotion of Solid particles with the help of an air flow, the Airflow is fed to a duct in the solid particles such as B. coal dust and the channel with is provided with a conical connector.
Bei den bekannten Vorrichtungen dieser Art ist die Wand des konusartigen Anschlußstückes eben ausgebildet.In the known devices of this type, the wall of the cone-like connector just formed.
Es hat sich gezeigt, daß bei einer Ausbildung eines konusartigen Anschlußstückes in dieser Art die Feststoffteilchen an den ebenen Wänden dieses Anschlußstückes sich ablagern, zumindest aber der Transport der Feststoffteilchen in diesem Bereich behindert ist.It has been shown that training a cone-like connector in this type Solid particles on the flat walls of this connector to deposit, but at least the transport of the Solid particles are hindered in this area.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Förderung von Feststoffteilchen mit konusartigem Anschlußstück so auszubilden, daß Ablagerungen im konusartigen Ansatzstück vermieden werden.The invention is therefore based on the object Device for conveying solid particles with Cone-shaped connector so that deposits can be avoided in the cone-like extension.
Das wird erfindungsgemäß dadurch erreicht, daß die Wand des konusartigen Ansatzstückes als bogenförmig gekrümmter Teil ausgebildet ist, dessen Krümmung in Strömungsrichtung gesehen zur Kanalachse gerichtet ist, so daß das konusartige Anschlußstück bauchige Gestaltung erhält, an die sich ein zylinderförmiger Teil mit stetiger Übergangsstelle anschließt.This is achieved in that the wall of the cone-like extension as an arcuate part is formed, the curvature seen in the flow direction is directed to the channel axis, so that the cone-like Receptacle with bulbous design, to which one cylindrical part with a continuous transition point connects.
Durch diese Ausbildung ist erreicht, daß sich im Bereich des bogenförmig gekrümmten Teils des Anschlußstückes ein Druck aufbaut, der zu einem Druckpolster führt, welches wiederum die Feststoffteilchen veranlaßt, beim Strömen durch den Kanal bzw. durch das konusartige Anschlußstück den Wandbereich zu meiden. Die Folge davon ist, daß Ablagerungen in diesem Bereich ausgeschlossen sind.This training ensures that in the area of arcuate curved part of the connector a pressure builds up, which leads to a pressure cushion, which in turn causing the particulates to flow through the channel or through the cone-like connector to the wall area avoid. The consequence of this is that deposits in this Area are excluded.
Damit keine Wirbelbildungen zwischen dem zylinderförmigen Teil des Anschlußstückes und dem bogenförmig gekrümmten Teil des Anschlußstückes entstehen, ist diese Übergangsstelle stetig ausgebildet, das heißt, ohne irgendeine Kantenbildung, die zu einer Verwirbelung der Strömung führen könnte.So that no vortex formation between the cylindrical Part of the connector and the arcuate part of the connector, this is the transition point steadily formed, that is, without any edge formation, which could lead to turbulence in the flow.
In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.In the drawing is an example embodiment shown.
Mit 1 ist der Kanal bezeichnet, der die Eintrittsöffnung 2 für die einzuführende Luft aufweist. Über die Einfüllöffnung 5 werden die Feststoffteilchen in den Kanal 1 eingeführt. An diesen Kanal 1 schließt sich ein kanalartiges Anschlußstück 6 an. Dieses kanalartige Anschlußstück hat eine besondere Ausbildung, und zwar in der Weise, daß die Wand dieses Anschlußstückes als bogenförmig gekrümmter Teil 3 ausgebildet ist, dessen Krümmung in Strömungsrichtung gesehen zur Kanalachse 4 gerichtet ist, so daß das konusartige Anschlußstück bauchige Gestalt 3a erhält, was durch die Pfeile angedeutet ist. An diese bauchartige Gestalt 3a des konusartigen Anschlußstückes schließt sich ein zylinderförmiger Teil 7 an, und zwar unter Aufrechterhaltung einer stetigen (Pfeil 7a) Übergangsstelle 8. 1 with the channel is designated, which has the inlet opening 2 for the air to be introduced. The solid particles are introduced into the channel 1 via the filling opening 5 . A channel-like connector 6 connects to this channel 1 . This channel-like connector has a special design, in such a way that the wall of this connector is designed as an arcuately curved part 3 , the curvature of which, viewed in the direction of flow, is directed towards the channel axis 4 , so that the cone-like connector has a bulbous shape 3 a, what is indicated by the arrows. A cylindrical part 7 adjoins this bulbous shape 3 a of the cone-like connecting piece, while maintaining a constant (arrow 7 a) transition point 8 .
Durch diese Ausbildung des kanalartigen Anschlußstückes bildet sich im Bereich der bauchigen Gestaltung dieses Anschlußstückes ein Druckpolster, welches die Wirkung hat, daß die im Kanal strömenden Feststoffteilchen die Wandberührung vermeiden.Through this design of the channel-like connector forms in the area of the bulbous design A pressure pad, which has the effect that the solid particles flowing in the channel Avoid touching the wall.
