Description
"Die Erfindung betrifft einen Trockner, insbesondere für keramisches Gut, bestehend aus einem umschlossenen, mit Ein- und Ausgangstoren für das Trockengut aufnehmende Wagen versehenen Raum, dessen Atmosphäre aufheizbar ist."The invention relates to a dryer, particularly for ceramic Well, consisting of an enclosed space with entrance and exit gates for the dry goods receiving car, its Atmosphere can be heated.
Das besondere Problem in solchen Trocknern besteht darin, daß der Trocknungsvorgang möglichst gleichmäßig durchgeführt wird, was bisher dadurch erreicht wurde, daß die Trockenzeit entsprechend lang ausgedehnt wurde. Lange Trockenzeiten bedeuten aber auch lange Standzeiten für das Trockengut und damit erheblichen finanziellen Aufwand, so daß die Aufgabe besteht, einen Trockner zu entwickeln, mit dem es möglich ist, nicht nur das Trockengut gleichmäßig zu trocknen, sondern auch in verhältnismäßig kurzen Zeiträumen.The particular problem in such dryers is that the drying process is carried out as uniformly as possible, which has been done so far was achieved by extending the drying time accordingly. But long drying times also mean long Downtimes for the material to be dried and thus considerable financial outlay, so that the task is to develop a dryer, with which it is possible not only to dry the items to be dried evenly, but also in relatively short periods of time.
Diese Aufgabe hat sich die Erfindung gestellt und löst sie durch einen Ventilator, der die Atmosphäre aus dem Raum über ein Heizregister absaugt und über an Seitenwandungen des Raums einander entgegengesetzt . ausmündende Zuführungskanäle wieder in den Raum einspeist, wobei die Menge und die Geschwindigkeit der gegeneinander gerichteten eingeführten Atmosphärenströme periodisch von einem Minimum auf ein Maximum und zurück derart geregelt werden, daß das Minimum des von der einen Seite kommenden Stromes mit dem Maximum des von der anderen Seite kommenden Stromes aufeinandertrifft.This problem has been set by the invention and it is achieved by a fan that draws the atmosphere out of the room Sucks off the heating register and opposes each other on the side walls of the room. outflowing feed channels feeds back into the room, with the amount and the speed of the opposing introduced atmospheric currents are periodically regulated from a minimum to a maximum and back so that the minimum of the coming from one side Current meets with the maximum of the current coming from the other side.
Damit wird in dem Trockenraum eine sich von der einen Seitenwandung zur anderen Seitenwandung hin- und herbewegende Atmosphäre erzielt, die das Trockengut gleichmäßig überstreicht und dadurch nicht nur in erhöhtem Maße für eine Abfuhr der im Trockengut enthaltenen Feuchtigkeit sorgt, sondern auch diese Feuchtigkeit über die Dauer gesehen gleichmäßig abführt. Auf diese Weise wird der angestrebte Erfolg, die Trocknungszeiten zu verringern unter gleichzeitiger Vergleichmäßigung des Trocknungszustandes des Trocknungsgutes in vollem Umfange erreicht. So that a side wall is in the drying room to the other side wall reciprocating atmosphere achieved, which sweeps over the dry goods evenly and thereby not only ensures that the moisture contained in the dry material is carried away to an increased extent, but also this moisture seen the duration dissipates evenly. In this way, the desired success is to reduce the drying times while at the same time Uniformity of the drying state of the goods to be dried achieved in full.

Die Zeichnung zeigt in einer einzigen Figur einen Querschnitt durch einen Trockner, insbesondere stationären Trockner gemäß der vorliegenden Erfindung.The drawing shows a cross section through in a single figure a dryer, in particular a stationary dryer according to the present invention.
Ein solcher Trockner kann sich auch über eine gewisse Länge erstrecken, d. h. mehrere das Trockengut aufnehmende Wagen aufzunehmen in der Lage sein.Such a dryer can also extend over a certain length, d. H. be able to accommodate a plurality of the dry goods receiving car.
Mit 1 und 2 sind die Seitenwandungen des Trockenraumes bezeichnet, in dessen Decke 3 sich Austrittsöffnungen für die Atmosphäre des Trockenraumes befinden, die von einem Ventilator 4 über ein Heizregister 5 in Leitungen 6 und 7 abgesaugt wird. Diese Leitungen münden in Einführungsvorrichtungen 8 bzw. 9, die beim wiedergegebenen Ausführungsbeispiel im unteren Teil des Trocknungsraumes ausmünden. Mit 10 ist ein Wagen bezeichnet, auf dem das schematisch bei 11 in Blockform angedeutete Trocknungsgut aufgestapelt ist. Es kann sich auch um eine andere Plattform handeln, die in irgendeiner Form in den Trocknungsraum eingeschoben werden kann.With 1 and 2 the side walls of the drying room are designated, in the ceiling 3 there are outlet openings for the atmosphere of the drying room, which are operated by a fan 4 via a heating register 5 is sucked off in lines 6 and 7. These lines open into insertion devices 8 and 9, which are shown in the Embodiment open out in the lower part of the drying room. 10 with a carriage is referred to on which the schematically at 11 indicated in block form drying material is stacked. It can also be another platform that is in any Form can be pushed into the drying room.
In den Leitungen 6 bzw. 7 befinden sich Sperrklappen 12 bzw. 13, \ die miteinander über ein Gestänge 14 verbunden und von einem Antriebsmotor M gesteuert sind. Man erkennt ohne weiteres aus der Zeichnung, daß die Umsteuerung derart erfolgt, daß einmal die Eintrittsöffnung 8 voll mit der Trocknungsluft beaufschlagt wird, während die Eintrittsöffnung 9 keinerlei Trocknungsluftzufuhr erhält. Umgekehrt kann die Steuerung auch in die andere Lage verstellt werden, wo die Eintrittsöffnung 9 voll mit Trocknungsatmosphäre beaufschlagt ist, während die Eintrittsöffnung 8 keinerlei Trocknungsatmosphäre einführt. Diese Verhältnisse sind durch die Kurven 15 bzw. 16 angedeutet, wobei auch eine mittlere Kurve 17 zu erkennen ist, die schematisch den Zustand der Umwälzung der Trocknungsatmosphäre wiedergibt, bei der die beiden Austrittsöffnungen 8 und 9 halb geöffnet sind, so daß sich das Maximum der Luftströmung im mittleren Bereich befindet.In the lines 6 and 7 are barrier flaps 12 and 13, \ connected to each other via a linkage 14 and controlled by a drive motor M. It can readily be seen from the drawing that the reversal takes place in such a way that the inlet opening 8 is once fully exposed to the drying air, while the inlet opening 9 does not receive any supply of drying air. Conversely, the control can also be moved into the other position, where the inlet opening 9 is fully exposed to the drying atmosphere, while the inlet opening 8 does not introduce any drying atmosphere. These relationships are indicated by the curves 15 and 16, a middle curve 17 can also be seen, which schematically reproduces the state of the circulation of the drying atmosphere, in which the two outlet openings 8 and 9 are half open, so that the maximum of the Air flow is in the middle area.
