Abstract

Pressurised chambers are filled with solid via a cylinder containing two or more pistons which can be displaced independently of each other. The sealing pistons are connected in such a way that ejection of gas from the pressure chamber is avoided. On filling, only the volume of gas stored in the bulk material is introduced into the pressure chamber. Previous preparation of the solid is not required.

Description

Feststoffe können in unter Druck stehende Reaktions­ räumen eingeschleust oder hineingedrückt werden.Solids can react in pressurized reaction are smuggled in or pushed in.

Zum Einschleusen ist mindestens ein absperrbarer Behälter erforderlich, der wechselseitig be- und entspannt werden kann. Abgesehen von den Problemen, die druckdichte Ab­ sperrorgane bei der Anwendung im Feststoffbereich mit sich bringen, müssen u. U. für das bei der Entspannung entweichende Gas besondere Maßnahmen getroffen werden.There is at least one lockable container for injecting required, which are mutually stressed and relaxed can. Aside from the problems, the pressure tight Ab locking devices when used in the solid range bring, u. U. for that when relaxing escaping gas special measures are taken.

Ein pneumatischer Eintrag ist wegen der hohen Ver­ dichtungsarbeit wirtschaftlich nicht durchführbar, außer­ dem gelangt zusätzlich Transportmedium in den Reaktions­ raum. Es eignet sich nur für trockene, feinkörnige Schüttgüter. A pneumatic entry is due to the high ver sealing work not economically feasible, except the additional transport medium gets into the reaction room. It is only suitable for dry, fine-grained Bulk goods.  

Eine andere Variante des Hineindrückens ist das Pumpen mit Dickstoffpumpen; im Gegensatz zur pneumatischen Ein­ bringung wird hier kein trockenes, sondern ein hin­ reichend feuchtes Fördergut vorausgesetzt, das aller­ dings einen gestuften Kornaufbau aufweisen sollte.Another variant of pushing in is pumping with thick matter pumps; in contrast to the pneumatic on Bring here is not a dry, but a go sufficiently moist material to be conveyed, provided that everyone However, should have a graded grain structure.

Alle o. g. Anforderungen entfallen bei dem erfindungsge­ mäßen Schubkolbenzuteiler. Das Fördergut kann in unver­ änderter Konsistenz übernommen werden; es gelangt keine Falschluft in den Reaktionsraum, es fällt keine abzu­ führende Entspannungsluft an und es werden keine staub­ beaufschlagten Absperrarmaturen benötigt.All of the above Requirements do not apply to the fiction moderate shear piston distributors. The conveyed goods can in un changed consistency are adopted; none comes False air in the reaction space, none falls off leading relaxation air and no dust shut-off valves required.

Der in Abb. 1 dargestellte Schubzuteiler besteht aus zwei in einem Zylinder (1) unabhängig voneinander arbeiten­ den Kolben (2) und (3), die abwechselnd die Füllrohre (4) und (5) und das Fallrohr (6) freigeben. Das Fallrohr (6) ist mit dem Reaktionsraum verbunden und steht unter dem entsprechenden Überdruck. Die Abdichtung gegen die unter Atmosphärendruck stehenden Füllrohre (3) und (4) wird von den Dichtungselementen (7) übernommen. The thrust distributor shown in Fig. 1 consists of two pistons ( 2 ) and ( 3 ) working independently in a cylinder ( 1 ), which alternately release the filling pipes ( 4 ) and ( 5 ) and the down pipe ( 6 ). The downpipe ( 6 ) is connected to the reaction chamber and is under the corresponding excess pressure. The sealing elements ( 7 ) take over the sealing against the filling pipes ( 3 ) and ( 4 ) which are under atmospheric pressure.

Die Funktionsweise ist in Fig. 2 beschrieben.The mode of operation is described in FIG. 2.

In der Position I befindet sich Kolben (2) in Endlage. Der zwischen Kolben (2) und Kolben (3) gebildete Füll­ raum V 1 wird über das Füllrohr (4) mit Fördergut teil­ weise gefüllt. Kolben (3) dichtet gegen den vom Fall­ rohr (6) ausstehenden Überdruck und verschließt gleich­ zeitig das Füllrohr (5). Das Ausschieben kann beginnen.In position I the piston ( 2 ) is in the end position. The filling space V 1 formed between the piston ( 2 ) and piston ( 3 ) is partially filled with material to be conveyed via the filling tube ( 4 ). Piston ( 3 ) seals against the excess pressure from the downpipe ( 6 ) and at the same time closes the filling pipe ( 5 ). The extension can begin.

Kolben (2) wird zunächst soweit vorgefahren, daß Füll­ rohr (4) abgesperrt wird (Pos.II). Dabei verkleinert sich der Füllraum (1) und das Fördergut wird verdichtet.Piston ( 2 ) is first advanced so far that filling tube ( 4 ) is shut off (item II). The filling space ( 1 ) is reduced and the material to be conveyed is compacted.

Nunmehr wird Kolben (3) soweit zurückgefahren, daß das Fallrohr (6) freigegeben wird. Kolben (2) fährt weiter vor und schiebt das verdichtete Fördergut in das Fall­ rohr (6) (Pos. III).Now piston ( 3 ) is retracted so far that the downpipe ( 6 ) is released. Piston ( 2 ) moves forward and pushes the compressed material into the downpipe ( 6 ) (item III).

Nachdem das Fördergut entleert worden ist, wird der Kolben (2) noch weiter vorgefahren, bis er das Fallrohr (6) abdichtet. Dabei wird der Kolben (3) zurückgeschoben und der Füllraum V 1 aufgehoben (Pos. IV). After the material to be conveyed has been emptied, the piston ( 2 ) is advanced even further until it seals the downpipe ( 6 ). The piston ( 3 ) is pushed back and the filling chamber V 1 is released (item IV).

Durch Zurückfahren des Kolbens (3) in seine Endlage wird der Füllraum V 2 gebildet. Der Füll- und Ausschiebe­ vorgang wiederholt sich sinngemäß auf der anderen Seite. (Pos.V).The filling chamber V 2 is formed by moving the piston ( 3 ) back into its end position. The filling and pushing out process is repeated on the other side. (Pos.V).

Ausgehend von diesem Prinzip sind weitere Ausführungs­ formen denkbar. So ist z. B. in Abb. 3a eine Einrichtung mit drei Kolben dargestellt. Dabei übernimmt der mittlere Kolben allein die Dichtfunktion gegenüber dem Fallrohr, während die anderen beiden Kolben die Absperrung der Füllrohre und das Ausschieben besorgen. Weil der mittlere Kolben unabhängig verfahren werden kann, ist es möglich, das Fallrohr abzusperren und die Füllräume nach dem Ent­ leeren aufzulösen. Dadurch wird ein Austritt vom Medium aus dem Reaktionsraum unterbunden. (Würden die Kolben starr verbunden, so fände ein Ausschleusen entsprechend dem starren Füllraumvolumen statt).Based on this principle, other forms of execution are conceivable. So z. B. in Fig. 3a, a device with three pistons. The middle piston performs the sealing function against the downpipe, while the other two pistons block the filling pipes and push them out. Because the middle piston can be moved independently, it is possible to shut off the downpipe and to empty the filling spaces after emptying. This prevents the medium from escaping from the reaction space. (If the pistons were rigidly connected, they would be discharged according to the rigid filling volume).

In Abb. 3b ist beispielhaft eine Ausführung mit nur einem Füllrohr wiedergegeben. Fig. 3b shows an example of a version with only one filling tube.

Verfahren zur Befüllung druckaufgeladener Räume mit Feststoffen, dadurch gekennzeichnet, daß die Befüllung

möglich ist. Dies wird dadurch erreicht, daß die Ver­ bindung von atmosphärischer(n) Füll-Leitung(en) und unter Druck stehender(n) Austragsleitung(en) durch einen Zylinder mit zwei oder mehreren unabhängig von­ einander verschiebbaren Kolben besteht.
Die dichtenden Kolben werden so geschaltet, daß ein Gasdurchtritt hinreichend vermieden wird. Durch ein Aneinanderfahren der Kolben nach dem Ausschieben des Feststoffs wird der frühere Füllraum aufgehoben und das darin befindliche unter Druck stehende Gas ver­ drängt. Bei anschließendem Zurückfahren beider Kolben wird das Ausschleusen von Druckgas verhindert.is possible. This is achieved in that the connection of atmospheric fill line (s) and pressurized discharge line (s) consists of a cylinder with two or more pistons which can be displaced independently of one another.
The sealing pistons are switched so that gas passage is sufficiently avoided. By moving the pistons together after pushing out the solid, the former filling chamber is canceled and the gas under pressure is displaced ver. When both pistons are subsequently moved back, the discharge of compressed gas is prevented.
