Description

AT 001 102 UlAT 001 102 Ul

Die Erfindung bezieht sich auf einen Fließbett-Trockner und/oder -Kühler mit einem gelochten, vorzugsweise in einer 5 Schwingrinne angeordneten Durchströmboden, auf dem das zu trocknende und/oder kühlende Gut von oben oder unten von der Trocken- und/oder Kühlluft durchströmt wird.The invention relates to a fluidized bed dryer and / or cooler with a perforated, preferably arranged in a 5 vibrating trough through which the drying and / or cooling material is flowed through from above or below by the dry and / or cooling air .

Derartige Fließbett-Trockner und/oder -Kühler werden zum 10 Trocknen und Kühlen von Schüttgut aller Art eingesetzt, wobei bei der üblichen Ausführung ein Lochblechboden in einer Schwingrinne angeordnet ist, auf dem das zu trocknende oder zu kühlende Material gefördert und zugleich von unten oder oben, vorzugsweise aber von unten, von Heiß- oder Kühlluft 15 durchströmt wird. Dieses System funktioniert jedoch nur, wenn die Lochgröße des Lochblechs, die Luftmenge, das Fördergut und die Fördermenge sinnvoll aufeinander abgestimmt sind. 20 Der Erfindung liegt daher die Aufgabe zugrunde, einen Fließbett-Trockner und/oder -Kühler zu schaffen, der sich in einfachster Weise an die jeweiligen Einsatzbedingungen, d.h. auf das jeweilige Fördergut und die Fördermenge, anpassen läßt. 25Such fluid bed dryers and / or coolers are used for drying and cooling bulk goods of all kinds, with a perforated plate base being arranged in a vibrating trough in the usual design, on which the material to be dried or cooled is conveyed and at the same time from below or above , but preferably from below, hot or cooling air 15 flows through. However, this system only works if the perforation size of the perforated plate, the air volume, the material to be conveyed and the volume conveyed are sensibly coordinated. 20 The invention is therefore based on the object of providing a fluidized bed dryer and / or cooler which can be adapted in a very simple manner to the respective operating conditions, i.e. can be adapted to the respective material to be conveyed and the quantity conveyed. 25th

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Lochgröße des Durchströmbodens veränderbar ist, was in Ausgestaltung der Erfindung bevorzugt dadurch erfolgt, daß der Durchströmboden aus zwei übereinander angeordneten, 30 aufeinander zur Erzielung unterschiedlicher Überlappungen der jeweiligen Lochbilder verschiebbaren Lochplatten, vorzugsweise Lochblechen, besteht. 2 AT 001 102 UlTo achieve this object, it is provided according to the invention that the hole size of the flow-through base can be changed, which in an embodiment of the invention preferably takes place in that the flow-through base consists of two perforated plates, preferably perforated plates, which are arranged one above the other and can be moved 30 to achieve different overlaps of the respective hole patterns. 2 AT 001 102 ul

Sowohl die untenliegenden, vorzugsweise tragenden und damit stärker ausgebildeten, Grundlochbleche als auch die bevorzugt unmittelbar darauf aufliegenden - in Sonderfällen aber auch in geringem Abstand darüber angeordneten - Oberbleche 5 können dabei mit unterschiedlichen Lochformen und/oder Lochgrößen versehen sein, d.h. es können anstelle von einfachen runden Löchern auch ovale Löcher, Schlitze od.dgl. vorgesehen sein, wobei die Oberbleche und die Rundbleche durchaus auch verschiedene Lochformen besitzen können. Da-10 bei kann selbstverständlich vorgesehen sein, daß die Lochbleche sowohl quer als auch längs zur Förderrichtung gegeneinander verschiebbar sind, wobei die Oberbleche und die Grundbleche bevorzugt stufenlos verstellbar in jeder Lage zueinander arretierbar sein sollen. 1 5Both the underlying, preferably load-bearing and thus more strongly designed, perforated metal sheets as well as the preferably directly lying on top of them - in special cases but also arranged at a short distance above them - top sheets 5 can be provided with different hole shapes and / or hole sizes, i.e. Instead of simple round holes, oval holes, slots or the like can also be used. be provided, the top plates and the round plates can also have different hole shapes. Da-10 at can of course be provided that the perforated plates are mutually displaceable both transversely and longitudinally to the conveying direction, the top plates and the base plates should preferably be lockable in any position relative to one another. 1 5

Zusätzlich zu der Möglichkeit, erfindungsgemäße Fließbett-Trockner und/oder -Kühler für unterschiedlichste Fördergüter verwenden zu können, indem man durch entsprechende Verschiebung der Lochplatten gegeneinander die jeweils gün-20 stigsten Betriebsbedingungen einstellt, können auch Bleche und Werkstoffe verwendet werden, die bisher aufgrund ihrer handelsüblichen Lochmaße und Blechstärken für den Eir.satz-fall im Fließbett-Trockner oder -Kühler nicht geeignet waren. 25In addition to the possibility of being able to use the fluid bed dryer and / or cooler according to the invention for a wide variety of conveyed goods by setting the most favorable operating conditions in each case by correspondingly displacing the perforated plates, sheet metal and materials can also be used which were previously the result of their commercially available hole dimensions and sheet thicknesses were not suitable for use in the fluidized bed dryer or cooler. 25th

Die Erfindung soll nachstehend anhand eines schematischen Ausführungsbeispiels sowie anhand der Zeichnung näher erläutert werden. Dabei zeigen: 30 Fig. 1 einen schematischen Schnitt durch einen erfindungsgemäßen Fließbett-Trockner oder -Kühler,The invention will be explained below with reference to a schematic embodiment and with reference to the drawing. 1 shows a schematic section through a fluid bed dryer or cooler according to the invention,

Fig. 2 eine vergrößerte Teilaufsicht auf den Durchströmbo-den der Anordnung nach Fig. 1, und 3 AT 001 102 UlFig. 2 is an enlarged partial plan view of the through-flow of the arrangement according to Fig. 1, and 3 AT 001 102 Ul

Fig. 3 eine Detailansicht eines abgewandelten Durchstrombodens . 5 In der Fig. 1 ist bei 1 eine Schwingrinne angedeutet, die mit einem gelochten Durchströmboden 2 versehen ist. Auf diesen gelochten Durchströmboden wird das zu trocknende oder zu kühlende Gut am Einlaß 3 aufgegeben und infolge des Schwingantriebs 4 und der schwingenden Aufhängeglieder 5 10 und 6 der Schwingrinne 1, die jedoch an sich bekannt sind und deshalb an dieser Stelle nicht näher beschrieben werden sollen, in Richtung des Auslasses 7 gefördert, in der das getrocknete oder gekühlte Gut abgenommen wird. Die Trocknung oder Kühlung erfolgt durch Zuführung von Trockenluft 15 oder Kühlluft über die Zuführleitung 8, die an unterschiedlichen Positionen 9 unter dem gelochten Durchströmboden 2 eingeblasen und mittels der schematischen Auslaßleitung 10 aus der die Schwingrinne überdeckenden Haube 11 abgesaugt wird. 20Fig. 3 is a detailed view of a modified through-flow tray. 5 In Fig. 1, a vibrating channel is indicated at 1, which is provided with a perforated through-flow floor 2. On this perforated flow-through floor, the material to be dried or cooled is fed in at the inlet 3 and, as a result of the oscillating drive 4 and the oscillating suspension members 5 10 and 6 of the oscillating channel 1, which are known per se and therefore will not be described in more detail here. promoted in the direction of the outlet 7, in which the dried or cooled goods are removed. The drying or cooling is carried out by supplying dry air 15 or cooling air via the feed line 8, which is blown in at different positions 9 under the perforated through-flow floor 2 and is sucked out of the hood 11 covering the vibrating channel by means of the schematic outlet line 10. 20th

Wie die Figur 2 zeigt, besteht der gelochte Durchströmboden 2 aus einem Grundlochblech 12 und einem darüber verschiebbar angeordneten Oberblech 13, die zur Erzielung unterschiedlicher Überlappungen der Lochbilder im Grundblech und 25 im Oberblech verschiebbar sind, so daß sich Überlappungen der Lochbilder ergeben können, die von 0 bis 100 % der Größe eines Einzellochs reichen.As FIG. 2 shows, the perforated throughflow floor 2 consists of a base perforated plate 12 and an upper plate 13 which is displaceably arranged above it and which can be moved in order to achieve different overlaps of the hole patterns in the base plate and 25 in the upper plate, so that there may be overlaps of the hole patterns which may occur 0 to 100% the size of a single hole is sufficient.

Neben der in Fig. 2 gezeigten Anordnung, bei der im Grund-30 blech und im Oberblech gleiche Bilder der Löcher 14 bzw. 15 vorgesehen sind, kann, wie in Fig. 3 angedeutet ist, auch vorgesehen sein, daß die Löcher 14 im Grundblech größer sind als die Löcher 15 im Oberblech und darüber hinaus kennen auch andere Lochformen vorgesehen sein, z.B. quadrati- 4 AT 001 102 Ul sehe, rechteckige, ovale und Langlochformen. Auch bei diesen unterschiedlichen Lochformen ist bevorzugt eine Kombination gewählt, bei der kleine Öffnungen im Oberblech vorgesehen sind, während das Unterblech jeweils größere Öff-5 nungen aufweist. Dies wirkt der Gefahr von Verkeilungen des Schüttguts in den sich unterschiedlich überdeckenden Löchern entgegen. 5In addition to the arrangement shown in FIG. 2, in which the same images of the holes 14 and 15 are provided in the base plate and in the top plate, as indicated in FIG. 3, it can also be provided that the holes 14 in the base plate are larger than the holes 15 in the top plate and also know other hole shapes can be provided, for example square 4 AT 001 102 Ul see, rectangular, oval and elongated hole shapes. In the case of these different hole shapes, too, a combination is preferably selected in which small openings are provided in the top plate, while the bottom plate in each case has larger openings. This counteracts the risk of the bulk goods becoming wedged in the differently overlapping holes. 5
