En/Lr.En / Lr.
Die Neuerung betrifft einen pneumatischen Förderer, insbesondere einen Förderer, "bei welchem ein zu transportierendes feinkörniges oder staubförmiges Gut mittels Druckluft stetig durch eine Rohrleitung gefördert wird.The innovation relates to a pneumatic conveyor, in particular a conveyor, "in which a fine-grained or dust-like material to be transported is continuously conveyed by means of compressed air is conveyed through a pipeline.
Derartige Fördereinrichtungen sind an sich bekannt und bestehen aus einer beispielsweise an der Entnahmeöffnung eines Bunkers angeordneten mechanischen Zuteilvorrichtung für das zu fördernde Gut, sowie einer oder mehreren, meist in einer ring- oder rohrförmigen Kammer angeordneten Druckluftdusen„Such conveying devices are known per se and exist from a mechanical dispensing device for the material to be conveyed, as well as one or more compressed air nozzles, usually arranged in an annular or tubular chamber "
Es hat sich nun gezeigt, daß die Förderleistung bei derartigen Fördereinrichtungen bei einem erheblichen Verbrauch an Druckluft unbefriedigend sein kann und insbesondere in der Düsenkammer oder in der Rohrleitung selbst unerwünschte Ablagerungen an Fördergut auftreten, die das funktionelle Arbeiten der Fördereinrichtung beeinträchtigen.It has now been shown that the delivery rate in such delivery devices with a considerable consumption Compressed air can be unsatisfactory and particularly undesirable deposits in the nozzle chamber or in the pipeline itself occur on conveyed goods that impair the functional work of the conveyor device.
Neuerungsgemäß wird daher zur Verbesserung der Förderleistung bei pneumatischen Förderern vorgeschlagen, die in einer mitunter τοη einem anderen Fördermittel beschickten Düsen- oder Zuteilkammer angeordneten Düsen eines pneumatischen Förderers als venturirohrartige Rohrkörper auszubilden.According to the innovation is therefore to improve the delivery rate proposed in the case of pneumatic conveyors, which occasionally loaded another conveyor in a τοη Form nozzle or dispensing chamber arranged nozzles of a pneumatic conveyor as a venturi tube-like tubular body.
Zur Verbesserung der Wirkung des Förderers kann die zwischen Düsenkammer und dem Förderrohr befindliche Anschlußstelle ebenfalls als ein venturirohrartiger Rohrkörper gestaltet werden.To improve the effect of the conveyor, the connection point located between the nozzle chamber and the conveyor pipe can be used can also be designed as a venturi-like tubular body.
In der Figur ist die Neuerung in einem Ausführungsbeispiel in schematisch vereinfachter Darstellung gezeigt.In the figure, the innovation is shown in an exemplary embodiment in a schematically simplified representation.

Mit 1 ist ein Entnahmegerät bezeichnet, dessen Abgabeöffnung 1' in eine in einffeohr geführte Förderschnecke 2 mündet, welche das Gut in die Düsen- und Düsenkammer 3 des pneumatischen Förderers einbringt«. Die Mündungsöffnung des Schneckenförderers 2 ist mit einer bewegbaren Klappe 4-verschließbar, um ein Wiedereintreten bereits in die Düsenkammer 3 eingetretenen Gutes in den Schneckenförderer zu vermeiden»1 with a removal device is referred to, the discharge opening 1 'opens into an infeed screw conveyor 2, which brings the material into the nozzle and nozzle chamber 3 of the pneumatic conveyor «. The mouth of the Screw conveyor 2 can be closed with a movable flap 4, in order to re-enter the material that has already entered the nozzle chamber 3 in the screw conveyor avoid"
In der Düsenkammer 3 sind mehrere von einer Druekluftzuleitung 5 ausgehende Düsen 6 —in der-Figur ist der besseren Übersicht halber nur eine Düse gezeigt —- angeordnet, durch welche Druckluft in die Düsenkammer 3 eingeblasen und das durch die förderschnecke 2 in die Düsenkammer eingetragene Gut in Pfeilrichtung durch das Rohr 7 zu einer entfernteren Verarbeitungs— und/oder Abgabestelle gefördert wird·In the nozzle chamber 3 there are several nozzles 6 emanating from a compressed air supply line 5 - only one nozzle is shown in the figure for the sake of clarity - through which compressed air is blown into the nozzle chamber 3 and the material carried into the nozzle chamber by the screw conveyor 2 is conveyed in the direction of the arrow through the pipe 7 to a more distant processing and / or delivery point.
Zur Vermeidung einer den lördervorgang abträglichen Wirb eisbildung innerhalb der Düsenkammer 3 sind die Düsen 6 als Venturirohre ausgebildet. Durch diese venturirohrartig gestaffelten Düsen entsteht eine gerichtete: Luftströmung hoher Geschwindigkeit, so daß die bereits erwähnten Nachteile,; der Wirbel- und Ablagerungsbildung von Fördergutteilchen, vermieden wird.To avoid a detrimental eddy ice formation within the nozzle chamber 3, the nozzles 6 are as Venturi tubes formed. Through this staggered venturi-like Nozzles creates a directional: air flow higher Speed, so that the disadvantages already mentioned; the formation of eddies and deposits of conveyed material particles, is avoided.
Durch Ausgestaltung der zwischen Düsenkammer und Förder— rohr 7 vorgesehenen Anschlußstelle 8 als Venturirohrkörper kann die 3?örder— und Wirkleistung des Förderers noch erheblich verbessert werden, wobei zudem der Verbrauch an Druckluft bei erhöhter lör&erleistung sinkt·By designing the connection point 8 provided between the nozzle chamber and the delivery pipe 7 as a Venturi pipe body the 3? conveying and active performance of the conveyor can still be improved considerably, with the consumption of compressed air with increased listening & performance decreases
