Description
Bekanntlich kann man viele körnige Schüttgüter mit sehr kleinen Luftgeschwindigkeiten aus Druckbehältern durch Rohrleitungen transportieren. Man benötigt dazu in der Regel jedoch Förderdrücke von I bis zu mehreren bar in dem Druckbehälter. Wird der Förderbehälter nun leer, dann expandiert das darin unter Druck stehende CJas zumeist schlagartig in die Förderleitung, was zu einer erheblichen S'Hgerung der Fördergas- und damit auch der Partikelgeschwindigkeit führt. Hierdurch entsteht einerseits beim Transport abrasiver Schüttgüter ein hoher Verschleiß der Förderleitung und andererseits eine oft unerwünschte Koin/erstörung bei empfindlichen Schüttgütern.It is well known that many granular bulk materials can be extracted from pressure vessels with very low air velocities transport through pipelines. As a rule, however, delivery pressures from 1 to several are required for this bar in the pressure vessel. If the conveying container is now empty, then that which is under pressure expands CJas mostly abruptly into the delivery line, which leads to a considerable increase in the delivery gas and thus also the particle velocity leads. On the one hand, this occurs when transporting abrasive bulk materials high wear of the delivery line and, on the other hand, often undesirable coin / destruction sensitive bulk goods.
Das Expandieren des unter Druck stehenden Fördergases kann man bekanntlich dadurch vermeiden, daß geniäU Fig. I nach Absinken des .Schüttgutspiegels auf das Niveau a ein Verschliißorgan 2 schließt und anschließend ein Viertel einer Lntspannungsleitung } öffnet. Gleichzeitig wird die Zufuhr von F'ördergas durch Schließen eines Ventils der Zuführleitung 4 unterbrochen. Auf diese Weise erfolgt die Entspannung des Druckbehälters nicht in die Förderleitung sondern über eine separate Leitung in einen nachgcschalteten Staubabscheider ader direkt in die Atmosphäre. Das Erreichen des Niveau a wird normalerweise durch eine Füllstandssonde 1 festgestellt. Zwar werden auf diese Weise die Förderleitung und das zu fördernde Schüttgut geschont; nachteilig ist aber, daß das Verschlußorgan 2, das im Produktstrom schließen muß, über Gebühr strapaziert wird.The expansion of the pressurized conveying gas can be avoided, as is well known, in that, after the bulk material level has dropped to level a, a wear member 2 closes and then a quarter of an expansion line opens. At the same time, the supply of conveying gas is interrupted by closing a valve in the supply line 4. In this way, the pressure vessel is not relieved of pressure into the delivery line, but rather via a separate line into a downstream dust separator or directly into the atmosphere. Reaching level a is normally determined by a level probe 1. It is true that the conveying line and the bulk material to be conveyed are spared in this way; However, it is disadvantageous that the closure member 2, which has to close in the product stream, is excessively stressed.
Der Erfindung liegt dit Aufgabe zugrunde, eine Einrichtung zum schonenden pneumatischen Transport von Schüttgut bei kleinen Schüttgutgeschwindigkeiten, mit einem das Schüttgut aufnehmenden Druckbehälter und einer Füllstamdssonde im Bereich des Druckbehälterauslaufs, die ein im selben Bereich angeordnetes Vet ;chlußorgan, ein Absperrventil einer Druckluftzufahrleitung und ein Öffnungsventil einer Entspannungsleitung für den Druckbehälter steuert, zu schaffen, die einen vorzeitigen Verschleiß des Verschlußorgans vermeidet.The invention is based on the object of a device for gentle pneumatic transport of bulk solids at low bulk solids speeds, with a pressure vessel that holds the bulk solids and a filling level probe in the area of the pressure vessel outlet, the one arranged in the same area Vet; chlußorgan, a shut-off valve of a compressed air supply line and an opening valve of a relief line for the pressure vessel controls to create the prevents premature wear of the closure member.
Diese Aufgabe ist bei der hier vorgeschlagenen Einrichtung erfindungsgemäß dadurch gelöst, daß die Füllstandssonde im Druckbehälterauslauf unterhalb des Verschlußorgans angeordnet ist.This object is achieved in the device proposed here according to the invention in that the Level probe is arranged in the pressure vessel outlet below the closure member.
Nach einer vorteilhaften Ausführungsform sind das Verschlußorgan und die Füllstandssonde in einer Verlängerung des Druckbehälterauslaufs angeordnet.According to an advantageous embodiment, the closure member and the level probe are in one Extension of the pressure vessel outlet arranged.
In der Zeichnung ist dne Einrichtung der bekannten Art und eine Einrichtung nach der Erfindung in beispielsweise gewählter Ausführungsform schematisch vereinfacht dargestellt Es zeigtIn the drawing the device is the familiar one Type and a device according to the invention in an example selected embodiment schematically Simplified it shows
F"ig. I die schon beschriebene, bekannte Einrichtung undFig. I shows the well-known device already described and
F i g. 2 die Einrichtung nach der Erfindung.F i g. 2 the device according to the invention.
Gemäß F i g. 2 ist bei einem Druckbehälter 10, der in bekannter Weise mit einem Befüllstutzen 8, einer Entspannungsleitung 3, einer Luftzufuhrleitung 4 sowie einer Füllstandssonde I und dem Anschluß an eine Förderleitung 5 versehen ist, die Füllstandssonde I in einer Verlängerung 6 des Druckbehälkr.iuslaufs untergebracht. Zwischen dem eigentlichen Druckbehälter 10 und der Behälterverlängerung 6 befindet sich das Verschlußorgan 2. Sinkt nun der Produktspiegel bis auf die Höhe der F'üllstandssonde I, so schließt /um Zweck der Behälterentspannung das Verschlußorgan 2. ohne durch das restliche Schüttgut 8 strapaziert und zerstört /u werden.According to FIG. 2 is in a pressure vessel 10, which in a known manner with a filling nozzle 8, a Relaxation line 3, an air supply line 4 and a level probe I and the connection to a Delivery line 5 is provided, the level probe I housed in an extension 6 of the Druckbehälkr.iuslaufs. The is located between the actual pressure vessel 10 and the container extension 6 Closure element 2. If the product level now sinks to the level of the filling level probe I, then the purpose is closed the container relaxation, the closure member 2 without stressed and destroyed by the remaining bulk material 8 / u will be.
