Description

Die Erfindung betrifft einen Brenngutträger für keramisches Material nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a firing tray for ceramic Material according to the preamble of claim 1.

Bei einem Brenngutträger der bekannten Art (DE 40 16 227 A1) handelt es sich um auf einem Brennwagen vorgesehene, keramische Tragstäbe, auf denen Ziegelformlinge in mehreren Etagen im luftumspülten Besatz angeordnet sind. Die Tragstäbe ruhen auf keramischen Stützelementen, die stoßempfindlich, sowie unelastisch sind und einen großen Platzbedarf haben.In the case of a firing tray of the known type (DE 40 16 227 A1) are provided on a kiln car, ceramic support rods on which brick moldings in several Floors are arranged in the air-washed trim. The support rods rest on ceramic support elements that are sensitive to shock, as well as inelastic and take up a lot of space to have.

Auch ein anderer Brenngutträger dieser Art (EP 0 208 249 A) weist ausschließlich aus keramischen Bestandteilen bestehende Stützelemente auf, welche die erwähnten Nachteile von keramischen Ausführungen haben.Another firing tray of this type (EP 0 208 249 A) has only ceramic components Support elements on which the disadvantages of have ceramic designs.

Es sind weiterhin Rungen aus Hohlprofilen bei Brennwagen bekannt (DE AS 12 95 760), die von Kühlmittel durchströmt werden. Diese Rungen dienen lediglich dazu das Brenngut auf dem Brennwagen seitlich zu sichern.There are still stanchions made of hollow profiles in kiln cars known (DE AS 12 95 760) through which coolant flows become. These stanchions are only used for firing to secure the kiln car laterally.

Auf dem Gebiet der Stahlverarbeitung ist es bekannt, von Kühlflüssigkeit durchströmte Tragrohre bei Transportsystemen vorzusehen (DE 37 16 532 C2), die metallisches Wärmgut, wie Knüppel, Blöcke oder Brammen aufnehmen. Das Wärmgut ruht dabei unmittelbar auf den von Wasser oder Öl durchströmten Rohren. Die Verwendung von Kühlflüssigkeit, wie sie auf dem Gebiet der Stahlverarbeitung für eine ausreichende Wärmeabfuhr unerläßlich ist, verbietet sich für Brenngutträger von keramischen Materialien. Der damit verbundene Aufwand ist extrem hoch und die sich ergebenden Temperaturunterschiede würden zu Wärmespannungen führen, die das Brenngut zerstörten.In the field of steel processing, it is known from Support pipes through which coolant flows in transport systems to provide (DE 37 16 532 C2), the metallic heating material, such as billets, blocks or slabs. The heating material rests directly on the one through which water or oil flows Pipes. The use of coolant, such as them in the field of steel processing for adequate Heat dissipation is essential for Firing trays of ceramic materials. The related Effort is extremely high and the resultant Differences in temperature would lead to thermal stresses that destroyed the kiln.

Der Erfindung liegt die Aufgabe zugrunde, einen Brenngutträger zu schaffen, der stoßfest und elastisch ausgebildet, sowie preisgünstig herstellbar ist. The invention has for its object a Brenngutträger to create the shockproof and elastic trained and is inexpensive to manufacture.

Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.The object is achieved by the features of patent claim 1 solved.

Der Brennwagen 1 besteht aus einem Fahrzeuggestell 5 mit Rädern 5a, das durch eine Isolierabdeckung 2 vor den hohen Temperaturen des Brennraums 14 geschützt ist. An dem Fahrzeuggestell 5 sind auf beiden Längsseiten Schiebebleche 5b befestigt, die in Verbindung mit Gegenblechen 21b den Bodenbereich 14c des Brennraums 14 von dem übrigen Brennraum 14 trennen. Auf dem Wagengestell 5 ruhen vertikale Stützen 4, an denen in mehreren Etagen Querträger 8 befestigt sind, in denen Tragstäbe 7 gelagert sind. Die keramischen Tragstäbe 7 nehmen das Brenngut 3 derart auf, daß es allseitig von Luft und/oder Brenngasen umspült werden kann. A combustion car 1 is located in a combustion chamber 14 of a furnace 21 guided longitudinally on rails 21a. The kiln car 1 consists of a vehicle frame 5 with wheels 5a, the through an insulating cover 2 from the high temperatures of the combustion chamber 14 is protected. On the vehicle frame 5 are attached to both long sides sliding plates 5b, the in connection with counter plates 21b the bottom area 14c of the Separate the combustion chamber 14 from the rest of the combustion chamber 14. On the Carriage frame 5 rest vertical supports 4, on which in several Floors cross member 8 are attached, in which support rods 7 are stored. The ceramic support rods 7 take that Firing material 3 in such a way that there is air on all sides and / or Fuel gases can be washed around.

In dem geschützten Bodenbereich 14c ist eine Kühlmittelzuleitung 13 untergebracht, in die ein Stutzen 12 hineinragt. Der Stutzen 12 ist mit einer Verteilerleitung 11 im Wagengestell 5 verbunden, die das gasförmige Kühlmittel den hohlen Stützen 4 zuführt, in denen es infolge der Kaminwirkung nach oben strömt und am oberen offenen Ende in den Brennraum 14 austritt.A coolant supply line is in the protected floor area 14c 13 housed, in which a nozzle 12 protrudes. The nozzle 12 is with a distribution line 11 in the car frame 5 connected, the the gaseous coolant the hollow Supports 4 in which it is due to the chimney effect flows upwards and at the upper open end into the combustion chamber 14 exits.

Fig. 2 stellt einen Brenngutwagen 1 im Längsschnitt dar, der auf Schienen 21a verfahrbar ist. Auf dem Wagengestell 5 sind hintereinander drei Stützen 4 befestigt, zwischen denen Tragstäbe 7 auf Konsolen 6 ruhen. Mit Hilfe der Konsolen 6 kann der Abstand zwischen den Tragstäben 7 der Höhe des Brennguts 3 angepaßt werden. Die Stützen 4 sind von einer Außenisolierung 9 umgeben. Jede Querreihe von Stützen 4 wird durch eine Verteilerleitung 11 mit Kühlmittel versorgt, die mit den Innenräumen der Stütze 4 verbunden ist und einen Stutzen 12 zum Andocken an eine Kühlmittelzuleitung 13 aufweist. Wie durch die Pfeile in Fig. 2 angedeutet, tritt das Kühlmittel oben an den Stützen 4 in den Brennraum 14 aus.2 shows a kiln car 1 in longitudinal section, which is movable on rails 21a. On the carriage frame 5 three supports 4 are attached one behind the other, between which Support rods 7 rest on brackets 6. With the help of the consoles 6, the distance between the support rods 7 of the height of the firing material 3 can be adjusted. The supports 4 are of one Outside insulation 9 surrounded. Each transverse row of supports 4 is supplied with coolant through a distributor line 11, which is connected to the interior of the support 4 and a connector 12 for docking to a coolant supply line 13 has. As indicated by the arrows in Fig. 2, the coolant occurs on the supports 4 in the Combustion chamber 14 out.

Wenn das Kühlmittel nicht oder nicht vollständig in den Brennraum 14 gelangen soll, kann der Hohlraum der Stütze 4', wie in den Fig. 3a und 3b gezeigt, durch eine Längstrennwand 10 in zwei Kühlkanäle 10a, 10b unterteilt werden, von denen der eine Kanal 10b als Rückführungsleitung dient. Die Stütze 4' ist dabei auf der Oberseite 4b' verschlossen. Zwischen der Oberseite 4b' und der Längstrennwand 10 verbleibt ein Spalt, der die Kühlkanäle 10a, 10b miteinander verbindet. Soll ein Teil des Kühlmittels in den Brennraum 14 gelangen, kann eine entsprechendbemessene Öffnung 15 an der Oberseite 4b' der Stütze 4' vorgesehen werden.If the coolant is not or not completely in the Combustion chamber 14 should reach, the cavity of the support 4 ', as shown in FIGS. 3a and 3b, by a Longitudinal partition 10 divided into two cooling channels 10a, 10b of which the one channel 10b as a return line serves. The support 4 'is on the top 4b' locked. Between the top 4b 'and the Longitudinal partition wall 10 remains a gap that the cooling channels 10a, 10b connects together. Part of the coolant get into the combustion chamber 14, a correspondingly dimensioned Opening 15 at the top 4b 'of the support 4 'are provided.

An der Stütze 4' sind Konsolen 6 befestigt (Fig. 3b), die die Außenisolierung 9 durchdringen. Die Konsolen 6 tragen Querträger 8, in denen nicht dargestellte, parallele Tragstäbe quer verlaufen.Brackets 6 are attached to the support 4 '(FIG. 3b) penetrate the outer insulation 9. Wear the consoles 6 Cross member 8, in which parallel support rods, not shown run across.

In Fig. 4 ist eine hängende Anordnung der Brenngutträger dargestellt. In der Brennraumdecke 14a sind Aufhängevorrichtungen 16 gelagert, die Stutzen 12' für die Kühlmittelzufuhr umschließen. Jede Aufhängevorrichtung 16 kann eine Stütze 4 tragen. Der Stutzen 12' ist mit der Stütze 4 gekuppelt. An den Stützen 4 sind die Tragstäbe 7 befestigt, auf denen das Brenngut 3 ruht. Der Brenn- und Trockungsprozeß kann verbessert werden, wenn die Brenngutträger um die Längsachsen 4a der Stützen 4 drehbar sind.In Fig. 4 is a hanging arrangement of the Brenngutträger shown. There are suspension devices in the combustion chamber ceiling 14a 16 stored, the nozzle 12 'for the coolant supply enclose. Each suspension device 16 can be one Wear support 4. The connector 12 'is coupled to the support 4. The support rods 7 are fastened to the supports 4, on which the kiln 3 rests. The firing and drying process can be improved if the firing tray supports the Longitudinal axes 4a of the supports 4 are rotatable.

Der Brennwagen 1' kann auch in einer Aussparung 14d im Brennraumboden 14b geführt werden. Während an der in Fig. 5 linken Stütze 4 das Brenngut 3 in Etagen auf Tragstäben 7 ruht, besitzt die rechte Stütze 4 Tragstäbe 7 in nur einer Ebene. Zwischen zwei parallel angeordneten Tragstäben 7 hängen Tonrohre 19 mit ihrem Flansch 19a. Bei schmalen Brennwagen 1' läßt sich der Brennraum 14 leichter abdichten und das Verhältnis von Besatz- zu Ballastgewicht verbessert sich.The kiln 1 'can also in a recess 14d in Combustion chamber floor 14b are performed. While at the in Fig. 5 left support 4, the firing material 3 on levels on supporting rods 7 rests, the right support has 4 support rods 7 in only one Level. Between two parallel support rods 7 hang clay pipes 19 with their flange 19a.
