(Anmeldung P 17 81 025.2) Druckluftförderanlage, bei der das Material in Gestalt von einzelnen sich folgenden Materialpfropfen durch die Leitung geführt wird.(Registration P 17 81 025.2) Compressed air conveyor system in which the material guided through the line in the form of individual plugs of material following one another will.
Bei der Druckluftförderanlage nach dem Hauptpatent ........ (Anmeldung P 17 81 025. 2) handelt es sich um eine Anlage, bei der das Material in Gestalt von einzelnen sich folgenden Materialpfropfen durch die Leitung geführt wird, mit einer parallel zur Förderleitung verlaufenden zusätzlichen Druckluftleitung kleineren Querschnitts, die in angemessenen Abständen durch Zweigrohre mit der Förderleitung verbunden ist. Dort sind in die Zweigrohre fremdbetätigte Ventile eingeschaltet und der Luftdruck in der zusätzlichen Leitung liegt erheblich, z.B. 2 - 3 atü über dem Druck in der Förderleitung. Es soIlen die einzelnen, sich in der Förderleitung folgender Materialpfropfen von einander getrennt gehalten und ihre Länge auf ein bestimmtes Maß begrenzt werden.In the case of the compressed air conveyor system according to the main patent ........ (registration P 17 81 025. 2) is a system in which the material in shape is guided through the line by individual following plugs of material, with an additional compressed air line running parallel to the delivery line is smaller Cross-section made at appropriate intervals through branch pipes to the delivery line connected is. There externally operated valves are switched on in the branch pipes and the air pressure in the additional line is considerable, e.g. 2 - 3 atm above the pressure in the delivery line. The individual should be in the delivery line following material plug kept separated from each other and their length to a be limited to a certain extent.
Nach der zusätzlichen Erfindung soll darüber hinaus der DruckabfalL in der Förderleitung beeinflußt werden, um einen ungestoirten Durchsatz des Materials- bei mässiger Geschwindigkeit und geringem Förderluftbedarf zu erreichen.According to the additional invention, the pressure drop should also be influenced in the conveying line in order to ensure an undisturbed throughput of the material to be achieved at a moderate speed and with little conveying air requirement.
An sich ist es bereits benannt, bei der Pfropfenförderung den Druckabfall über die Länge der Förderleitung stufenweise zu vergleichmässigen. Besonders vorteilhaft ist jedoch eine solche Maßnahme im Zusammenhang mit einer Anlage nach dem Hauptpatent.In itself it has already been mentioned, the pressure drop in plug conveying Gradually equalize over the length of the delivery line. Particularly beneficial however, such a measure is in connection with a system according to the main patent.
Dazu sind die dort erwähnten Ventile mit Mitteln zur Dosierung des Luft durchtritts versehen, zum Zweck, den Druckabfall über die Lange der Förderleitung stufenweise zu vergleichmässigen.For this purpose, the valves mentioned there are equipped with means for metering the Air passage is provided for the purpose of reducing the pressure drop over the length of the delivery line gradually to equalize.
Die Mittel zur Dosierung des Luftdurchtritts können Zeitschaltwerke sein, die die Öffnungszeiten der Ventile bestimmen Eine andere Möglichkeit besteht darin, für die Dosierung des Luftdurciitntts die Ventile selbst als Drosseleinrichtungen auszubilden oder mit solchen zu versehen.The means for metering the air passage can be timers that determine the opening times of the valves Another possibility exists in it, for the metering of the air pressure, the valves themselves act as throttling devices to train or to provide such.
Diese Drosseleinrichtungen können einstellbare Reduzierventile sein, um den Druckabfall in der Förderleitung nach Ausprobieren bzw. nach den Erfordernissen des zu fördernden Materials einzustellen, In der Zeichnung sind zwei Ausführungsbeispiele der erfindungsgemässen Druckförderanlage schematisch dargestellt, und zwar zeigt Fig. 1 eine derartige Anlage, bei der die Öffnungszeiten der Ventile in den Zweigrohren nach dem mittleren örtlichen Druck in der Förderleitung gesteuert werden, und Fig. Z eine andere Anlage dieser Art, bei der in die Zweigrohre vom mittleren örtlichen Druck in der Förderleitung gesteuerte Reduzierventile eingeschaltet sind.These throttling devices can be adjustable reducing valves, the pressure drop in the delivery line after trial and error or according to requirements of the material to be conveyed. The drawing shows two exemplary embodiments the inventive pressure conveyor system shown schematically, namely shows Fig. 1 such a system, in which the opening times of the valves in the branch pipes can be controlled according to the mean local pressure in the delivery line, and Fig. Z another system of this type, in which in the branch pipes from the central local Pressure in the delivery line controlled pressure reducing valves are switched on.
In beiden Fällen verläuft paraIlel zur Förderleitung 1 eine Druckluftleitung 2 kleineren Querschnitts, in welcher der Luftdruck über demjenigen der Förderleitung ist, teilweise erheblich, z. B. 2-5 atü. Die zusätzliche Druckluftleitung 2 ist durch Zweigrohre 3 in angemessenen Abständen mit der Förderleitung 1 vcrbunden. In die Zweig rohre 3 sind Magnetventile 4 eingeschaltet. An den Einmündungsstellen sind Rückschlagklappen 5 vorgeschen. Ausserdem ist jeder Einmündungsstelle eine Meßstelle zugeordnet, die aus einer aus einer Lichtquelle oder Infrarotquelle 6 und einer Fotozelle 7 gebildeten Lichtschranke besteht. Jede Fotozelle steht über einen Verstärker 8 mit dem betreffenden Magnetventil 4 in Verbindung. Vortcilhaft können auch radioaktive Meßschranken verwendet werden.In both cases, a compressed air line runs parallel to the delivery line 1 2 smaller cross-section in which the air pressure is higher than that of the delivery line is, in some cases considerably, e.g. B. 2-5 atü. The additional compressed air line 2 is connected to the delivery line 1 by branch pipes 3 at appropriate intervals. In the branch pipes 3 solenoid valves 4 are turned on. At the confluence points check valves 5 are provided. In addition, each confluence point is one Assigned measuring point, which consists of a light source or infrared source 6 and a photocell 7 formed light barrier. Each photocell protrudes an amplifier 8 with the respective solenoid valve 4 in connection. Beneficial radioactive measuring barriers can also be used.
Beim ersten Ausführungsbcispiel ist jedem Verstärke 8 ein Zeitschaltwerk 10 zugeordnet, das von einem Druckmeßgerät 11 beeinflussbar ist.In the first exemplary embodiment, each amplifier 8 is a timer 10 assigned, which can be influenced by a pressure measuring device 11.
Dieses steht in der Nähe der jeweiligen Einmündungsstelle des betr. Zweigrohres 3 mit der Förderleitung 1 durch ein verhältnismässig enges Rohr 12 in Verbindung.This is in the vicinity of the respective junction of the respective Branch pipe 3 with the delivery line 1 through a relatively narrow pipe 12 in Link.
Beim Durchgang eines jeden Materialpfropfens 9 durch die Förderleitung 1 wird jeweils kurz vor dem Einlangen an der nächsten Druckluft-i;inmündungsstelle die jeweilige Lichtschranke 6, 7 durchbrochen. Dadurch wird ein Impuls ausgelöst, der. durch den Verstärker 8 verstärkt, das zugehörige Magnetventil 4 öffnet und sofort wieder schließt. Dtr eindringende Druck luftstoß genügt. um die Länge des Materialpfropfens 8 zu begrenzen und ein Aufschieben desselben auf den vorangehenden Pfropfen zu verhindern.When each material plug 9 passes through the delivery line 1 is released shortly before it arrives at the next compressed air outlet the respective light barrier 6, 7 broken through. This triggers an impulse the. amplified by the amplifier 8, the associated solenoid valve 4 opens and closes again immediately. Dtr penetrating compressed air is sufficient. by the length of the To limit material plug 8 and pushing the same onto the preceding one Prevent clogging.
Dabei wird die Öffnungszeit der Ventile 4 in Abhängigkeit vom jeweiligen mittleren Druck an den Eintrittsstellen der Zweigrohre 3 in die Förderleitung 1 derart bestimmt. daß durch Dosierung des Luftdurchtritts der Druckabfall über die Länge der Förderleitung stufenweise vergleichmässigt wird.The opening time of the valves 4 is dependent on the respective mean pressure at the entry points of the branch pipes 3 into the delivery line 1 so determined. that by metering the air passage the pressure drop across the The length of the delivery line is gradually evened out.
Beim zweiten Ausführungsbeispiel bleiben die Öffnungszeiten der Ventile 4 unverändert. Dagegen stehen hier die Druckmeßgeräte 11 mit Reduzierventilen 13 in den Zweigrohren 3 in Verbindung. Hier werden also die Reduzierventile 13 entsprechend dem mittleren örtlichen Druck in der Förderleitung verstellt und so der Luftdurchtritt im Sinne einer stufenweise Vergleichmässigung des Druckabfalles in der Förderleitung 1 geregelt. In the second embodiment, the opening times of the valves remain 4 unchanged. On the other hand, there are pressure measuring devices 11 with reducing valves 13 in the branch pipes 3 in connection. So here the reducing valves 13 are accordingly adjusted to the mean local pressure in the delivery line and thus the air passage in the sense of a gradual equalization of the pressure drop in the delivery line 1 regulated.
