Abstract

The conveyor consists of a feeder and inflatable membrane cushion locking elements in which the air cushions are superimposed in pairs over each other with a time lag regulation between the sealing of the upper and lower cushion sets.

Zusatzanmeldung der Patentanmeldung P 20 42 115.2 'Pneumatischer Kunststoff-Förderer mit Dosiereinrichtung und gasdichter Donpelachleuse' In der Hauptanmeldung wird ein Euststoff-Pörderer mit einer Dosiereinrichtung beschrieben, in der die Zuteileinrichtung aus Schließschächten besteht, die zur Abdichtung mit elastischen aufblähbaren Membrankissen versehen sind, die über ein Steueraggregat intervallmäßig, erfordernisgerecht geöffnet oder geschlossen werden können.Additional application of patent application P 20 42 115.2 'Pneumatic plastic conveyor with dosing device and gas-tight Donpelachleuse 'In the main application a Euststoff-Pörderer described with a metering device in which the metering device consists of lock shafts that are used for sealing with elastic, inflatable membrane cushions are provided, which are opened at intervals via a control unit as required or can be closed.

Bei der pneumatischen Kunststoff-Börderung wird vielfach mit Schutzgas gearbeitet. Beim Offnen der erfindungsgemäßen Schleuse würde z.B. Schutzgas aus dem pneumatischen Umluftsystem in den Granulatbehälter eindringen können. Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, unter dem Zuteiler eine Yörderdüsenanordnung 9 zu wählen, die einen Sog im Bereich 10 erzeugt. Wird die Anlage still gesetzt und Gas aus dem Vorratasilo oder anstehendes Gas aus dem Umluftfördersystem darf nicht in das Silo eindringen, so würde, da die unterdruckerzeugende 9üse außer Funktion ist, eytl.In the pneumatic conveying of plastics, inert gas is often used worked. When the lock according to the invention is opened, protective gas, for example, would be emitted the pneumatic circulating air system can penetrate into the granulate container. For this Basically, it is proposed according to the invention to have a delivery nozzle arrangement under the distributor 9 to choose, which creates a suction in area 10. The system is shut down and gas from the storage silo or existing gas from the air circulation system is allowed do not penetrate into the silo, the vacuum-generating nozzle would be inoperative is, eytl.

Gas durch die eingequetschten Granulatteilchen 11, die zwischen elastischen Membrankissen eingeklemmt liegen, in den Silo oder umgekehrt aus dem Silo diffundieren. Um dieses zu vermeiden, wird erfindungsgemäß vorgeschlagen, zwei der erfindungsgemäßen aufblähbaren Membrankissenverschlüsse untereinander oberhalb der pneumatischen förderleitung zu verlagern, die so mit einem Steuerorgan 12 in Verbindung stehen, daß beim Abschalten über ein Zeitrelais erst die Abschlußorgane 13 sich schließen und ii Pörderfluß befindliche Kunststoff-Granulate in den Dichtflächen der Membrankissen einquetachen und nach kurzem Zeitabstand sich erst dann die Membrankissen des Schließorgans 14 gasdicht schließen, da hier keine Kunststoff-Granulatteilchen beim Schließvorgang vorhanden sind.Gas through the squeezed granules 11, which are between elastic Membrane cushions are trapped, diffuse into the silo or vice versa out of the silo. In order to avoid this, the invention proposes two of the invention inflatable membrane cushion closures above the pneumatic conveying line to relocate, which are so connected to a control member 12 that when switching off Only the closing organs 13 close via a time relay and ii Pörderfluss Squeeze any plastic granules in the sealing surfaces of the membrane cushions and only then after a short time interval do the membrane cushions of the closing member 14 Close gas-tight, as there are no plastic granulate particles during the closing process available.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne Jedoch von dem Grundgedanken abzuweichen, einen Kunststoff-Förderer mit gasdichter DoppelBchleuse zu verwenden, wobei die Doppelschleuse aus untereinander angeordneten pneu. oder flüssigkeit druck-abhängig verschließbaren Meibrankissen besteht, die über ein Steuerorgan in gewünschter abhängiger Zeitfolge nacheinander geschlossen werden, so daß mindeNeSs ein Schleusentell der untereinander angeordneten Ioppelschleuse ohne Materialeinschluß gasdichtend aufeinander liegt.Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Modifications possible without deviating from the basic idea, a plastic conveyor to be used with a gas-tight double lock, the double lock from one another arranged pneu. or Meibrank cushions that can be closed as a function of the liquid pressure exists, which one after the other via a control unit in the desired dependent time sequence are closed, so that at least one lock plate of the one below the other Ioppelschleuse without material inclusion lies on top of one another in a gas-tight manner.
