Description

Stromtrockner mit gleichachsig ineinandergesetzten Hohlsäulen Die Erfindung betrifft einen Stromtrockner mit gleichachsig ineinandergesetzten Hohlsäulen, in deren innerer, oben offener, das Trocknungsgut emporgeführt wird, um in der äußeren Säule herabzusinken. Das Neue besteht darin, daß ein nach oben erweitertes, gegebenenfalls gelochtes Führungsrohr von gleichem unterem Durchmesser wie die innere Säule über dieser gleichachsig und lotrecht verschiebbar angeordnet ist. Vorteilhaft wird an dem Führungsrohr zur Einstellung des oberen Austrittsquerschnittes ein schwenkbarer Schirm oder ein anderes Mittel vorgesehen, und an der Innenwand der äußeren Säule können Leitrippen angeordnet werden, die zweckmäßig einstellbar ausgebildet sind.Current dryer with coaxially nested hollow columns Die The invention relates to a flow dryer with coaxially nested hollow columns, in the interior of which, open at the top, the material to be dried is carried up to the exterior Column to sink down. The novelty consists in the fact that something expanded upwards, if necessary perforated guide tube of the same lower diameter as the inner column this is arranged coaxially and vertically displaceable. Is beneficial to the guide tube to adjust the upper exit cross-section a pivotable Screen or other means provided, and on the inner wall of the outer column guide ribs can be arranged, which are expediently designed to be adjustable.

Gegenüber den bekannten Einrichtungen ähnlicher Art hat die Erfindung den Vorteil, daß das Trocknungsgut wahlweise gar nicht, teilweise oder ganz durch das Führungsrohr geleitet und damit die Gutverweilzeit im Trockner etwaigem raschem Wechsel der Betriebsverhältnisse, vor allem den Trocknungseigenschaften des Gutes angepaßt werden kann.Compared to the known devices of a similar type, the invention the advantage that the material to be dried either not at all, partially or completely guided the guide tube and thus the product dwell time in the dryer any faster Change of operating conditions, especially the drying properties of the goods can be customized.

Die Zeichnung stellt schematisch Ausführungsbeispiele der Erfindung dar und zeigt in Abb. 1 einen Stromtrockner in lotrechtem Schnitt, in Abb. 2 in größerem Maßstab ein anderes Ausführungsbeispiel und in Abb. 3 einen Schnitt nach Linie III-III der Abb. 2. Der Weg des Trocknungsgases ist durch weiße, der des Trocknungsgutes durch schwarze Pfeile gekennzeichnet.The drawing shows schematically exemplary embodiments of the invention and shows in Fig. 1 a flow dryer in vertical section, in Fig. 2 in on a larger scale another embodiment and in Fig. 3 a section according to Line III-III of Fig. 2. The path of the drying gas is through white, that of the goods to be dried marked by black arrows.

Das durch die Aufgabe 10 der Trocknungsgaszuleitung 11 aufgegebene Trocknungsgut wird von dem Gas durch die innere Hohlsäule 12 emporgeführt. Über deren oberem Ende ist das mittels des Zahnritzelgetriebes 13 lotrecht verstellbare Führungsrohr 14 angeordnet, dessen Durchmesser unten gleich dem der Hohlsäule 12 ist, um sich nach oben hin zu erweitern. Der sich erweiternde Teil 15 seiner Wand hat Durchbrüche 16. Je nach der Einstellung des Führungsrohres 14 strömt das Trocknungsgas mitsamt dem Trocknungsgut - wie hier gezeichnet -über den oberen Rand der inneren Hohlsäule 12 vollständig sogleich in die äußere Hohlsäule 17 hinüber, um hier hinabzusinken, wobei seine Bewegung durch an der Innenwand der äußeren Hohlsäule 17 einstellbar angebrachte Schaufelrippen 18 beeinflußt werden kann. Je mehr das Führungsrohr 14 gesenkt wird, um so mehr strömt ein Teil von Gas und Gut durch dieses hindurch aus den Durchbrüchen 16 heraus oder über den oberen Führungsrohrrand, womit die Verweilzeit im Stromtrockner äußerst feinfühlig geregelt werden kann. In dem an die äußere Hohlsäule 17 angeschlossenen Zyklon 19 werden dann Gas und Gut getrennt, das erste wird durch die Leitung 20 abgeleitet, das zweite durch die Schleuse 21 entnommen.The abandoned by the task 10 of the drying gas supply line 11 Material to be dried is carried up by the gas through the inner hollow column 12. Above the upper end of which is vertically adjustable by means of the pinion gear 13 The guide tube 14 is arranged, the diameter of which at the bottom is the same as that of the hollow column 12 is to expand upwards. The expanding part 15 of its wall has openings 16. Depending on the setting of the guide tube 14, the drying gas flows together with the items to be dried - as shown here - over the upper edge of the inner Hollow column 12 immediately over into the outer hollow column 17 in order to sink down here, its movement being adjustable through on the inner wall of the outer hollow column 17 attached blade ribs 18 can be influenced. The more the guide tube 14 is lowered, the more a part of gas and material flows out through it the openings 16 out or over the upper edge of the guide tube, thus reducing the dwell time can be regulated extremely sensitively in the flow dryer. In the one on the outer hollow column 17 connected cyclone 19 are then separated gas and material, the first is through the line 20 diverted, the second taken through the lock 21.

Um die Regelung der Bewegung von Gas und Gut noch zu verfeinern, ist bei dem in Abb. 2 und 3 dargestellten Ausführungsbeispiel in das Rohr 22, das das Führungsrohr 14 trägt, eine mit dem Handgriff 23 drehbare Stange 24 eingesetzt. Die das Führungsrohr mit dem Rohr 22 verbindenden Tragarme sind hier zu schirmartigen Sektoren 25 verbreitert, und ähnliche Sektoren 26 sind am unteren Ende der Stange 24 befestigt. Durch Drehen dieser Stange 24 in dem Rohr 22 lassen sich die Sektoren 25 und 26 mehr oder weniger miteinander decken, wodurch die obere Öffnung des Führungsrohres 14 und damit sein freier Austrittsquerschnitt verändert wird.In order to refine the regulation of the movement of gas and goods, is in the embodiment shown in Fig. 2 and 3 in the pipe 22, which Guide tube 14 carries, a rotatable with the handle 23 rod 24 is used. The support arms connecting the guide tube to the tube 22 are umbrella-like here Sectors 25 widened and similar sectors 26 are at the bottom of the rod 24 attached. By rotating this rod 24 in the tube 22, the sectors 25 and 26 more or less cover each other, whereby the upper opening of the guide tube 14 and thus its free outlet cross-section is changed.

Die in der äußeren Hohlsäule 17 angebrachten Schaufelrippen 18 haben vorteilhaft zueinander entgegengesetzte Steigungen, um ein kräftiges Hinundherwirbeln des sich abwärts bewegenden Gases und Gutes hervorzurufen.The blade ribs 18 attached in the outer hollow column 17 have Advantageously opposing inclines to allow a strong swirling back and forth of the downward moving gas and goods.
