Description

Brenngutträger Firing trays
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 AI) handelt es sich um auf einem Brennwagen vorgesehene, keramische Tragstäbe, auf denen Ziegelformlinge in mehreren Etagen im luftumspülten Besatz angeordnet sind. Die Trag- stäbe ruhen auf keramischen Stützelementen, die stoßempfindlich, sowie unelastisch sind und einen großen Platzbedarf haben.A firing tray of the known type (DE 40 16 227 AI) is a ceramic support rods provided on a firing car, on which brick moldings are arranged on several levels in the air-flushed trim. The support rods rest on ceramic support elements that are sensitive to impact, are inelastic and require a lot of space.
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 also stanchions made of hollow profiles in kiln cars (DE AS 12 95 760) through which coolant flows. These stanchions only serve to secure the firing material on the side of the firing car.
Auf dem Gebiet der Stahlverarbeitung ist bekannt, von Kühl- flüssigkeit 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. Für keramisches Brenngut sind derartige Tragrohre nicht geeignet, da die Temperaturunterschiede infolge der schlechten Wärmeleitfähigkeit des keramischen Materials zu Wärmespannungen führten, die das Brenngut zerstörten.In the field of steel processing, it is known to provide support pipes through which cooling liquid flows in transport systems (DE 37 16 532 C2), which hold metallic heating material, such as billets, blocks or slabs. The heating material rests directly on the pipes through which water or oil flows. Support tubes of this type are not suitable for ceramic firing material, since the temperature differences as a result of the poor thermal conductivity of the ceramic material lead to thermal stresses which destroy the firing material.
Der Erfindung liegt die Aufgabe zugrunde, einen Brenngut- träger zu schaffen, der stoßfest und elastisch ausgebildet, sowie preisgünstig herstellbar ist. Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst .The object of the invention is to create a firing tray which is designed to be shock-proof and elastic, and which is inexpensive to produce. The object is achieved by the features of patent claim 1.
Vorteilhaft Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements of the invention result from the subclaims.
Durch die Innenkühlung der Stützen werden tragfähige, elastische und gegen Temperaturschwankungen unempfindliche Materialien für die vertikalen Stützen verwendbar.Thanks to the internal cooling of the supports, stable, elastic and temperature-resistant materials can be used for the vertical supports.
Nachstehend werden mehrere bevorzugte Ausführungsformen der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:Several preferred embodiments of the invention are described in detail below with reference to the drawings. Show it:

In einem Brennraum 14 eines Ofens 21 ist ein Brennwagen 1 längsverschieblich auf Schienen 21a geführt. 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. 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 hoh- len Stützen 4 zuführt, in denen es infolge der Kaminwirkung nach oben strömt und am oberen offenen Ende in den Brennraum 14 austritt.In a combustion chamber 14 of a furnace 21, a combustion car 1 is guided in a longitudinally displaceable manner on rails 21a. The kiln 1 consists of a vehicle frame 5 with wheels 5a, which is protected by an insulating cover 2 from the high temperatures of the combustion chamber 14. Sliding plates 5b are fastened to the vehicle frame 5 on both longitudinal sides and, in conjunction with counter plates 21b, separate the bottom region 14c of the combustion chamber 14 from the rest of the combustion chamber 14. On the carriage frame 5 rest vertical supports 4, on which cross members 8 are fastened in several floors, in which support rods 7 are mounted. The ceramic support rods 7 receive the firing material 3 in such a way that air and / or fuel gases can wash around them on all sides. A coolant supply line 13, into which a connecting piece 12 projects, is accommodated in the protected base area 14c. The connecting piece 12 is connected to a distributor line 11 in the carriage frame 5, which feeds the gaseous coolant to the hollow supports 4, in which it flows upwards as a result of the chimney effect and exits into the combustion chamber 14 at the upper open end.
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 ei- ner 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 angedeu- tet, tritt das Kühlmittel oben an den Stützen 4 in den Brennraum 14 aus.Fig. 2 shows a Brenngutwagen 1 in longitudinal section, which is movable on rails 21a. On the carriage frame 5 three supports 4 are fastened one behind the other, between which support rods 7 rest on brackets 6. With the help of the brackets 6, the distance between the support rods 7 of the height of the firing material 3 can be adjusted. The supports 4 are surrounded by external insulation 9. Each transverse row of supports 4 is supplied with coolant by a distributor line 11, which is connected to the interior of the support 4 and has a connection 12 for docking with a coolant supply line 13. As indicated by the arrows in FIG. 2, the coolant exits into the combustion chamber 14 at the supports 4.
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 entspre- chendbemessene Öffnung 15 an der Oberseite 4b' der Stütze 4' vorgesehen werden.If the coolant should not or not completely get into the combustion chamber 14, the cavity of the support 4 ', as shown in FIGS. 3a and 3b, can be divided by a longitudinal partition wall 10 into two cooling channels 10a, 10b, one of which channel 10b serves as a return line. The support 4 'is closed on the top 4b'. A gap remains between the upper side 4b 'and the longitudinal partition wall 10, which connects the cooling channels 10a, 10b to one another. If part of the coolant is to get into the combustion chamber 14, a corresponding can be provided at the top 4b 'of the support 4'.
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, which penetrate the outer insulation 9, are fastened to the support 4 '(FIG. 3b). The brackets 6 carry cross members 8, in which parallel support rods, not shown, extend transversely.
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 Trockungspro- zeß kann verbessert werden, wenn die Brenngutträger um die Längsachsen 4a der Stützen 4 drehbar sind.4 shows a hanging arrangement of the firing tray. Suspension devices 16 are mounted in the combustion chamber ceiling 14a and enclose the connecting pieces 12 'for the coolant supply. Each suspension device 16 can carry a support 4. The connector 12 'is coupled to the support 4. On the supports 4, the support rods 7 are fastened, on which the firing material 3 rests. The firing and drying process can be improved if the firing tray can be rotated about the longitudinal axes 4a of the supports 4.
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 combustion car 1 'can also be guided in a recess 14d in the combustion chamber floor 14b. While on the left-hand support 4 in FIG. 5, the firing material 3 rests on support rods 7 in tiers, the right-hand support 4 has support rods 7 in only one plane. Clay pipes 19 hang with their flange 19a between two support rods 7 arranged in parallel. In the case of narrow kiln cars 1 ', the combustion chamber 14 can be sealed more easily and the ratio of stocking weight to ballast weight improves.
