Description
Die heute in Betrieb befindlichen Hordentrockner für loses Gut erreichen einen annähernd gleichmäßigen Wassergehalt nur bei sehr langer Trockendauer und Temperaturen, die meist über 60 ° C liegen. Es ist bei der Betrachtung eines derartigen Hordentrockners leicht zu erkennen, daß die unterste und die oberste Horde der heißen Trockenluft am meisten ausgesetzt sind, während die mittleren Horden der Einwirkung nur im geringeren Maße unterliegen. Man hat dies umgehen wollen durch Führung der Horden innerhalb des Trocknergehäuses im Gleichoder Gegenstrom zur Trockenluft; auch den Hordenwagen bewegt man bei Kanaltrocknern mit verschiedenen Beheizungsstufen. Hierzu sind aber große und teure Apparate nötig, und die Beanspruchung der Faser wächst. Die Trocknung beeinflußt die Beao schaflenheit der Faser in hohem Maße; ihre wertvollen Eigenschaften, die zur Verarbeitung notwendig sind, gehen zum Teil verloren; die Verkürzung der Trockenperiode durch hohe Temperaturen bedeutet jedenfalls eine Schädigung. Wolle verliert durch scharfe Trocknung an Weichheit und Geschmeidigkeit, sie wird hart und spröde. Bei Baumwolle läßt die Dehnung mit zunehmender Temperatur sehr schnell nach. Je niedriger die Temperatur ist, desto schonender erfolgt die Trocknung; dies kann nur eingehalten werden, wenn eine zweckmäßige Luftführung die größtmögliche Berührung des Fasergutes mit derselben sichert. Diese Luftführung wird dadurch erreicht; daß man die Bespannung des Drahtbodens der Horden gemäß der Erfindung abändert. Der Strömungsweg der Trockenluft durch den Trockenwagen oder Trockengestell ist hierbei folgender:The tray dryers in operation today for loose goods come close to reaching you Uniform water content only with very long drying times and temperatures, which are mostly above 60 ° C. It is when considering such a tray dryer easy to see that the lowest and the uppermost horde of hot dry air are most exposed, while the middle hordes are only exposed to im are subject to lesser dimensions. They wanted to get around this by leading the hordes inside the dryer housing in cocurrent or countercurrent to the drying air; also the Rack trolleys are moved with tunnel dryers with different heating levels. However, this requires large and expensive apparatus necessary, and the stress on the fiber increases. The drying affects the Beao sharpness of the fiber to a large extent; their valuable properties necessary for processing are necessary are partly lost; In any case, the shortening of the dry period through high temperatures means an injury. Wool loses its softness and suppleness due to sharp drying, it becomes hard and brittle. In the case of cotton, the stretching decreases very quickly with increasing temperature. The lower the temperature, the gentler the drying process; this can only be observed if an appropriate air flow ensures the greatest possible contact between the fiber material and the same. This air flow is achieved in this way; that one changes the covering of the wire bottom of the trays according to the invention. The flow path of the drying air through the drying trolley or drying rack is here the following:
Die bisher üblichen, aus Vollblech hergestellten Seitenwände i, 2H 3, 4 der Horden I, III, V werden entfernt und durch solche aus Drahtgitter oder Lochblech ersetzt (i, 2, 5, 6 in Fig. 2).The previously customary side walls i, 2 H 3, 4 of the shelves I, III, V made of solid sheet metal are removed and replaced by those made of wire mesh or perforated sheet metal (i, 2, 5, 6 in FIG. 2).
Bei den Horden II, IV, VI wird der Drahtboden in der Mitte keilförmig von den Kanten i, 2 und 3, 4 nach oben gezogen so daß die Keilschneide 5, 6 in der Höhe der Stirnwandoberkanten liegt (Fig. 3).In the case of the Horde II, IV, VI, the wire shelf in the middle becomes wedge-shaped from the edges i, 2 and 3, 4 pulled upwards so that the wedge cutting edge 5, 6 is level with the upper edge of the front wall lies (Fig. 3).
Die Luft ist nun gezwungen, das Trockengut vollkommen zu umspülen, da sie den Weg des geringsten Widerstandes geht (Fig. 1).. Da der Zwischenraum α eng ist, tritt sie in der Mitte durch die unterste Horde VI, umspült deren Inhalt oben und den der nächsten Horde V unten. An der Stelle b findet sie wieder bequem Durchgang nach oben, bei c staut sich die Luft und zieht zwischen den Horden V und VI nach der Mitte, wo sie durch die Horde IV weiter nach oben strömt. In der gleichen Weise umspült sie die Horden III, II und. I.The air is now forced to completely wash around the dry material, since it takes the path of least resistance (Fig. 1) .. Since the space α is narrow, it passes in the middle through the lowest shelf VI, washes around the contents above and that of the next Horde V below. At point b it again finds a convenient passage upwards, at c the air accumulates and pulls between the shelves V and VI towards the middle, where it flows further up through the shelves IV. In the same way, she washes around Hordes III, II and. I.
Die bei a, c, e durchtretende Luft wird sich dem geringen Querschnitt entsprechend schneller bewegen und wirkt an den Punkten b, d, f saugend auf die aus der Mitte austretende Luft. Eine Aussparung bei / würde sich erübrigen, da ohnedies an dieser Stelle der Ventilator die Luft absaugt.The air passing through at a, c, e will move faster according to the small cross-section and has a sucking effect on the air exiting from the center at points b, d, f. A recess at / would be superfluous, since the fan sucks the air out at this point anyway.
