Abstract
Description
Die Erfindung bezieht sich auf einen Durchlauftrockner für keramisches Gut, der zwischen Presse und Brennofen angeordnet ist.The invention relates to a continuous dryer for ceramic material arranged between the press and the kiln is.
Trockner sind in den verschiedensten Bauformen bekannt. Meistens wird für die Trocknung der noch nassen Teile Abwärme aus dem eigentlichen Brennofen benutzt.Dryers are known in a wide variety of designs. Mostly there is waste heat for the drying of the still wet parts used from the actual kiln.
Die Aufgabe der vorliegenden Erfindung besteht darin, den Durchlauftrockner hinsichtlich der Energieausnutzung zu optimieren.The object of the present invention is that Continuous dryer with regard to energy utilization optimize.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Trockner in einzelne Längsabschnitte unterteilt ist, in denen eine gezielte Heißluftströmung in Längsrichtung zwischen dem zu trocknenden Brenngut erzeugbar ist.This object is achieved in that the Dryer is divided into individual longitudinal sections in which a targeted hot air flow in the longitudinal direction between the firing material to be dried can be generated.
Auf diese Weise kann die Heißluft in Kanälen in Längsrichtung zirkulieren, die durch entsprechend aufgeschichteten Besatz, z. B. Ziegelsteine gebildet werden. Durch diese Längskanäle wird eine intensive und schnelle Trocknung der Steine erreicht.In this way, the hot air canals in the longitudinal direction circulate through appropriately layered trimmings, e.g. B. bricks are formed. Through these longitudinal channels becomes an intensive and quick drying of the stones reached.
In jedem der Längsabschnitte wird die Heißluft eingeblasen, durchströmt die Kanäle und wird anschließend wieder abgesogen. Die abgesogene Luft wird dann entsprechend behandelt, z. B. getrocknet, erhitzt und/oder mit zusätzlicher Luft angereichert.The hot air is blown into each of the longitudinal sections, flows through the channels and is then back again sucked. The extracted air then becomes corresponding treated, e.g. B. dried, heated and / or with additional Air enriched.
Durch das abschnittsweise Einblasen und Absaugen ergibt sich insgesamt gesehen über den ganzen Trockner hin eine gleichmäßige Strömung. The blowing and suctioning in sections results a total of one across the entire dryer even flow.
Der Trockner ist vorteilhaft ferner am Ein- und Ausgang mit Schleusen versehen, die durch Tore gebildet werden. In die Einfahrschleuse wird dabei zweckmäßigerweise ebenfalls Heißluft eingeblasen, um eine Taupunktunterschreitung zu vermeiden.The dryer is also advantageous at the entrance and exit Provide locks that are formed by gates. In the The entrance lock is also expedient Hot air blown in in order to fall below the dew point avoid.
Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels sei die Erfindung näher erläutert; es zeigen:Using one shown in the drawing The embodiment is explained in more detail; it demonstrate:
Fig. 1 einen schematischen Längsschnitt durch den zwischen Presse und Brennofen angeordneten Durchlauftrockner, Fig. 1 shows a schematic longitudinal section through which is arranged between the press and kiln flow dryer

Fig. 3 Details der Einfahrschleuse. Fig. 3 details of the entrance lock.
Fig. 4 Details der Heißlufteinblasung. Fig. 4 details of hot air injection.
Der zum Trocknen des Brenngutes 6 dienende Durchlauftrockner 2 ist zwischen der Presse 1 und dem eigentlichen Brennofen 3 angeordnet. Am Eingang bzw. Ausgang des Durchlauftrockners 2 befinden sich Schleusen 11 bzw. 10.The continuous dryer 2 used to dry the firing material 6 is arranged between the press 1 and the actual kiln 3 . At the entrance or exit of the continuous dryer 2 there are locks 11 and 10, respectively.
Wie insbesondere aus Fig. 2 ersichtlich, ist das Brenngut 5 derart zu Mauern 6 aufgeschichtet, daß sich zwischen ihnen Längskanäle 7 ergeben. Dieser gewählte Besatz auf dem Transportwagen 4 bleibt dann auch im Brennofen erhalten. Durch die gebildeten Kanäle 7 wird trocknende Heißluft geführt. Hierzu ist der Trockner 2 in eine Vielzahl von Abschnitten 20 unterteilt, in denen jeweils zumindest ein Teil der Heißluft 8 im Kreislauf so geführt ist,daß sie gezielt in die Kanäle 7 einströmt und sie in Ofenlängsrichtung durchströmt. Mit anderen Worten, jedem Abschnitt sind ein oder mehrere sich über die Breite des Trockners erstreckende Einblasungen und entsprechende Absaugungen zugeordnet, damit dieser Kreislauf ausgeführt werden kann. Im Kreislauf sind dabei Gebläse 12 und weitere Behandlungsvorrichtungen angeordnet, mit denen die Trocknungsluft getrocknet bzw. beheizt werden kann. As can be seen in particular from FIG. 2, the firing material 5 is layered into walls 6 in such a way that longitudinal channels 7 result between them. This selected stock on the trolley 4 is then retained in the kiln. Drying hot air is passed through the channels 7 formed. For this purpose, the dryer 2 is divided into a plurality of sections 20 , in each of which at least part of the hot air 8 is guided in the circuit in such a way that it flows specifically into the channels 7 and flows through them in the longitudinal direction of the furnace. In other words, each section is assigned one or more blow-ins and corresponding suction devices which extend across the width of the dryer, so that this cycle can be carried out. Blowers 12 and further treatment devices with which the drying air can be dried or heated are arranged in the circuit.
Zur Steuerung der Lufteinblasung in den Trockner 2 dienen Luftleitbleche 13, die an der Decke 21 des Trockners befestigt sind. Hierdurch wird gesichert, daß die Heißluft 8 nur in die Kanäle 7 strömt.Air baffles 13 , which are attached to the ceiling 21 of the dryer, are used to control the air injection into the dryer 2 . This ensures that the hot air 8 only flows into the channels 7 .
Durch die insgesamt geschilderte Anordnung wird die am Ausgang des Trockners eingeblasene Heißluft 9 mehrfach gleichmäßig durch die einzelnen Reihen des Brenngutes geführt, verläßt dann am Eingang des Trockners diesen und strömt zum nicht dargestellten Abgaskamin. Um in der Einfahrschleuse 11 Taupunktunterschreitungen zu vermeiden, wird auch in diese Schleuse Heißluft 22 eingeblasen.Due to the arrangement described as a whole, the hot air 9 blown in at the outlet of the dryer is guided several times uniformly through the individual rows of the combustion material, then leaves the latter at the inlet of the dryer and flows to the exhaust gas chimney, not shown. In order to avoid falling below the dew point in the entrance lock, hot air 22 is also blown into this lock.
Fig. 3 zeigt Details dieser Schleuse 11, und zwar besteht sie im wesentlichen aus zwei Toren 14 und 15, die in Doppelpfeilrichtung 17 bzw. 18 bewegbar sind. Das Tor 14 ist dabei stationär, wohingegen das Tor 15 mit der Schubvorrichtung 16 in Richtung des Doppelpfeiles 19 mitfahren kann. Fig. 3 shows details of this lock 11 , namely it consists essentially of two gates 14 and 15 which are movable in the double arrow direction 17 and 18 respectively. The gate 14 is stationary, whereas the gate 15 can travel with the pushing device 16 in the direction of the double arrow 19 .
Eine ähnliche Schleusenkonstruktion, bei der mit einem Leerwagen gearbeitet wird, der die Wagenreihe abdichtet, wird am Ausgang des Trockners 2 vorgesehen.A similar lock construction, in which an empty wagon is used, which seals the row of wagons, is provided at the exit of the dryer 2 .
Wie Fig. 4 erkennen läßt, ist jeder Abschnitt 20 strömungsmäßig in zwei Einblashälften 26, 27 zerlegt. Die beiden Hälften werden abwechselnd durch Umstellen der Klappe 23 in der Leitung 22 mit Heißluft 8 versorgt. Hierdurch wird eine örtliche Überhitzung vermieden. Der durch die Öffnung 25 aus dem Trockenraum abgezogenen Luft wird abhängig von der gemessenen Temperatur und/oder Feuchte zusätzliche Heißluft aus Leitung 24 zugeführt.As can be seen in FIG. 4, each section 20 is divided in terms of flow into two injection halves 26 , 27 . The two halves are alternately supplied with hot air 8 by moving the flap 23 in line 22 . This prevents local overheating. Depending on the measured temperature and / or humidity, additional hot air is supplied from line 24 to the air drawn through the opening 25 from the drying room.
