Abstract

The suction nozzle pneumatically conveys loose material through a suction pipe (2) encircled by an axially adjustable tubular casing (3). The suction pipe has openings (7) for auxiliary air, which can be closed off by an axially-movable, short tubular sleeve (8) on the suction pipe. The openings (7) are located near to the free end of the suction pipe below the lever (9) of the loose material and near to the central part of the tubular casing. The sleeve (8) can be used to only partially close the auxiliary air holes (7). The lower end of the suction nozzle lies a distance t below that of the tubular casing (3).

(Patentanmeldung P 23 21 286.4-22 Durch das Hauptpatent ist an einer Saugdüse zum pneumatischen Fördern eines Schüttgutes, die von dem freien Ende eines Ansaugrohres in der Form eines Rohrstückes und einem Mantelrohr gebildet wird, das in der Nähe der Eintrittsöffnung des Rohrsttickes endet, unter Schutz gestellt, daß das Mantel rohr in axialer Richtung verstellbar ist und sein freies Ende in einem Abstand t2 vom freien Ende der Saugdüse fest einstellbar ist. Hierdurch wird erreicht, daß die Druckverhältnisse im Bereich der Eintritts öffnung der Saugdüse unabhängig von der sich ändernden Eintauchtiefe der Saugdüse konstant sind. (Patent application P 23 21 286.4-22 by the main patent is on one Suction nozzle for the pneumatic conveying of a bulk material, which from the free end of a Intake pipe is formed in the form of a pipe section and a jacket pipe, which ends near the inlet opening of the pipe section, placed under protection, that the jacket tube is adjustable in the axial direction and its free end in a distance t2 from the free end of the suction nozzle is firmly adjustable. This will achieved that the pressure conditions in the area of the inlet opening of the suction nozzle regardless of the changing immersion depth of the suction nozzle constant are.

Bei der Weiterentwicklung der Saugdüse nach dem Hauptpatent wurde gefunden, daß besonders gute Ergebnisse erzielt werden, wenn das Ansaugrohr mindestens eine verschließbare Öffnung für Hilfsluft aufweist.In the further development of the suction nozzle according to the main patent was found that particularly good results are achieved when the suction pipe is at least has a closable opening for auxiliary air.

Vorzugsweise werden mehrere Öffnungen für Hilfsluft am Umfang des Ansaugrohres verteilt angeordnet und mit Hilfe eines verschiebbaren Ringkörpers mehr oder weniger verschlossen. Die Öffnungen können in der Nähe des freien Endes des Ansaugrohres liegen oder im Abstand von diesem bis zu einer Stelle oberhalb des in axialer Richtung verstellbaren Mantelrohres.Preferably, several openings for auxiliary air on the circumference of the Intake pipe arranged distributed and with the help of a movable ring body more or less closed. The openings can be near the free end of the suction pipe or at a distance from it up to a point above of the adjustable casing tube in the axial direction.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles, das in der Zeichnung rein schematisch dargestellt ist, näher beschrieben. Die erfindungsgemäße Saugdüse 1 umfaßt ein Ansaugrohr 2 in Form eines Rohrstückes, das von einem Mantelrohr 3 umgeben ist und in der Nähe der Eintrittsöffnung 4 des Ansaugrohres 2 endet. Das Mantelrohr 3 ist längs des Ansaugrohres 2 in axialer Richtung verstellbar, damit sein freies Ende 5 in einem Abstand t2 von dem freien Ende 6 des Ansaugrohres 2 fest einstellbar ist.The invention is explained below using an exemplary embodiment, which is shown purely schematically in the drawing, described in more detail. The inventive Suction nozzle 1 comprises a suction pipe 2 in the form of a pipe section which is supported by a jacket pipe 3 is surrounded and ends in the vicinity of the inlet opening 4 of the intake pipe 2. That Casing pipe 3 is adjustable along the suction pipe 2 in the axial direction so that its free end 5 at a distance t2 of the free end 6 of the Suction pipe 2 is permanently adjustable.

Die Verstelleinrichtung für das Mantelrohr 3 ist in der Zeichnung nicht dargestellt.The adjusting device for the jacket tube 3 is shown in the drawing not shown.

Das Ansaugrohr 2 weist mindestens eine, vorzugsweise jedoch mehrere an seinem Umfang verteilt angeordnete Öffnungen 7 auf. Diese Öffnungen 7 lassen sich mit Hilfe eines axial verschiebbaren Ringkörpers 8 stufenlos verschließen, wodurch die Menge der in das Ansaugrohr 2 einströmenden Hilfsluft geregelt wird. In der Darstellung verschließt der Ringkörper 8 die Öffnungen 7 teilweise.The suction pipe 2 has at least one, but preferably several Openings 7 arranged distributed on its circumference. Let these openings 7 close steplessly with the help of an axially displaceable ring body 8, whereby the amount of auxiliary air flowing into the intake pipe 2 is regulated. In the illustration, the ring body 8 partially closes the openings 7.

Der Ringkörper 8 wird in Richtung des Pfeiles "a" zur Regelung der "ilfsluftmenge verschoben und auf dem Ansaugrohr 2 festgeklemmt, was in der Zeichnung ebenfalls nur schematisch dargestellt ist.The ring body 8 is in the direction of arrow "a" to regulate the "Shifted ilfsluftmasse and clamped on the intake pipe 2, which is in the drawing is also only shown schematically.

Die Öffnungen 7 im Ansaugrohr 2 befinden sich vorzugsweise in axialer Richtung oberhalb des Mantelrohres 3. Dies ist aber nicht unbedingt erforderlich. So können sie gegebenenfalls auch innerhalb des Mantelrohres 3 liegen, beispielsweise unterhalb des Schüttgutspiegels 9 in der Nähe der Eintrittsöffnung 4 des Ansaugrohres 2 oder innerhalb des mittleren bzw. oberen Bereiches des Mantelrohres, der sich teitweise oberhalb bzw.The openings 7 in the intake pipe 2 are preferably located axially Direction above the jacket pipe 3. However, this is not absolutely necessary. So they can optionally also lie within the jacket tube 3, for example below the bulk material level 9 in the vicinity of the inlet opening 4 of the suction pipe 2 or within the middle or upper area of the jacket tube, which is partially above or

zeitweise unterhalb des beim Betrieb wechselnden Schüttgutspiegels 9 befindet, wie aus der Lage der gestrichelt dargestellten Öffnungen 7 hervorgeht.temporarily below the bulk material level, which changes during operation 9 is located, as can be seen from the position of the openings 7 shown in dashed lines.

Die Erfindung ist bezüglich ihrer konstruktiven Gestaltung nicht auf das in der Zeichnung dargestellte Ausführungsbeispiel beschränkt, vielmehr können Änderungen vorgenommen werden, ohne daß dadurch von dem grundsätzlichen Erfindungsgedanken abgewichen wird0The invention is not related to its structural design the embodiment shown in the drawing is limited, rather can Changes can be made without thereby affecting the basic concept of the invention deviated from 0
