Description
Anlage zum pneumatischen Fördern von Schüttgut Die Erfindung betrifft eine Anlage zum Fördern von Schüttgut mittels zweier oder mehrerer sogenannter Blastanks, die so angeordnet sind, daß bei abwechselndem Füllen oder Entleeren ein Regler beeinflußt wird, der die zum Wechseln der Förderung erforderlichen Umschaltmittel steuert, und zwar besteht die Erfindung darin, daß in der Zeit der Umschaltung, wo kein Druck in der Förderleitung vorhanden ist, durch eine absperrbare Umführungsleitung die Druckluft der Förderleitung unmittelbar zugeführt wird, zum Zweck der Vermeidung, von Verstopfungen in der Förderleitung.Plant for the pneumatic conveying of bulk material The invention relates to a system for conveying bulk material by means of two or more so-called blow tanks, which are arranged in such a way that a regulator influences the alternating filling and emptying which controls the switching means required to change the funding, namely, the invention consists in that in the time of switching where no pressure is present in the delivery line, through a lockable bypass line the Compressed air is supplied directly to the delivery line, for the purpose of avoiding of blockages in the delivery line.
Abb. i und a zeigen schematisch ein Aus führungsbeispiel der Erfindung.Fig. I and a show schematically an exemplary embodiment of the invention.
z und 2 sind Blastanks, die aus dem Bunker 3 abwechselnd gefüllt werden, und zwar über den Dreiweghahn q., der entweder den Zulauf zu dem Blastank i oder 2 freigibt oder absperrt.z and 2 are blow tanks that are filled alternately from bunker 3, namely via the three-way valve q., which is either the inlet to the blow tank i or 2 releases or blocks.
Die Förderleitung i I ist mit jedem der Blastanks i und 2 verbunden, und zwar ist es durch den Dreiweghahn 6 ebenfalls möglich, die Förderleitung i i abwechselnd mit jedem der beiden Blastanks i und 2 zu verbinden oder von ihnen abzusperren. Diesen beiden Anordnungen entsprechend ist auch die Zuführung der Druckluft durch die Leitung io über den Dreiweghahn 5 ausgebildet. Außerdem aber hat die Druckluftleitung io noch einen absperrbaren Abzweig 7 mit einem Ventil 12, der die Leitung io mit der Förderleitung i i unmittelbar verbindet.The delivery line i I is connected to each of the blow tanks i and 2, namely it is also possible through the three-way valve 6, the delivery line i i to be alternately connected to each of the two blow tanks i and 2 or to be shut off from them. The supply of compressed air is also in accordance with these two arrangements the line io formed via the three-way valve 5. In addition, however, the compressed air line has io another lockable branch 7 with a valve 12, which connects the line io with the delivery line i i directly connects.
Beide Blastanks i und 2 stehen auf einem Waagebalken, so daB, wenn ein Tank leer ist und der andere gefüllt wird, das Mehrgewicht den einen zum Sinken bringt, während der andere Tank dadurch zum Steigen gebracht wird, und zwar um einen feststehenden Betrag. Außerdem wird die jeweilige Füllung eines jeden Tanks auf der Waage 9 gewogen und aufgezeichnet.Both blow tanks i and 2 stand on a balance beam, so that if one tank is empty and the other is filled, the extra weight makes one sink while the other tank is raised by one fixed amount. In addition, the respective filling of each tank is based on the balance 9 weighed and recorded.
Die Dreiweghähne oder Ventile werden nun durch einen Regler 8 in gewisser Reihenfolge gesteuert. Den Anstoß hierzu erhält der Regler 8 von dem gefüllten Tank, wenn er den tiefsten Stand erreicht hat, oder von dem leeren Tank, wenn dieser den höchsten Stand erreicht hat.The three-way cocks or valves are now by a regulator 8 in a certain way Order controlled. The controller 8 receives the impetus for this from the filled tank, when it has reached the lowest level, or from the empty tank, when this the has reached the highest level.
Die Wirkungsweise des Verfahrens und der Einrichtung ist folgende: Vom Bunker 3 wird das Fördergut durch den Dreiweghahn q. dem Blastank i zugeführt. Dieser sinkt entsprechend seinem Füllungsgrad und hebt den leeren oder nur teilweise gefüllten Tank 2 in die Höhe. Hat Tank i seinen tiefsten Stand erreicht, d. h. ist er gefüllt, so erfolgt ein Anstoß des Reglers 8 und dieser sperrt die Zufuhr durch den Dreiweghahn .4 ab und gibt sie zu dem Tank 2 frei. Darauf verbindet der Regler Förderleitung I I durch den Dreiweghahn 6 mit dem Blastank i und die Preßluftleitung io durch den Dreiweghahn 5 mit dem Tank i. Das Fördergut wird hinausgedrückt, der Tank i wird leichter und steigt, während Tank :2 inzwischen gefüllt wird. Nach dem Füllen gibt Tank :2 den Anstoß zum Umstellen,der Hähne, und es wiederholt sich das Spiel unter Vertauschung der Tanks.The mode of operation of the procedure and the facility is as follows: From the bunker 3, the conveyed material is through the three-way valve q. fed to the blow tank i. This sinks according to its filling level and lifts the empty one or only partially filled tank 2 upwards. Has tank i reached its lowest level, i.e. H. is if it is filled, the controller 8 is triggered and this blocks the supply the three-way cock .4 and releases it to the tank 2. The controller then connects Delivery line I I through the three-way valve 6 with the blow tank i and the compressed air line io through the three-way valve 5 with the tank i. The conveyed material is pushed out, the Tank i becomes lighter and rises, while tank: 2 is now being filled. After this Filling gives the tank: 2 the impetus to switch over, the taps, and it repeats itself Game by swapping the tanks.
Um nun die Förderleitung i i während der Zeit, wo der Druckluft Dreiweghahn 5 umgeschaltet wird, nicht ohne Druck zu lassen, wird das Ventil 1:2 geöffnet und hierdurch die Druckluftleitung io über Leitung 7 mit der Förderleitung i i verbunden. Auf diese Weise wird mit zwei oder mehreren Blastanks eine ununterbrochene Förderung erreicht.To now the delivery line i i during the time when the compressed air three-way valve 5 is switched over without leaving pressure, the valve is opened 1: 2 and as a result, the compressed air line io is connected to the delivery line i i via line 7. In this way, uninterrupted pumping is achieved with two or more blow tanks achieved.
