Abstract

The system of wall construction is for use in tunel furnaces or kilns having an exterior screening or facing wall, an inner fire clay plastered wall and an insulating wall set up between these two walls. The fire-clay wall (3) consists of a pair of component walls (3a, 3b) which are set at a small distance from each other. These component walls (3a, 3b) are connected by vertical beams or bars (7) construced of fire clay bricks (6) which allow the formation of air cassettes (8) which run vertically within the fire clay wall (3). Insulation layers (4) are provided between the fireclay walls and the outer lining wall (5).

Description

Die Luftkassetten 8 sind nicht mit der Außenluft verbunden, so daß die Luft innerhalb der Luftkassetten 8 als stehend bezeichnet werden kann. The air cassettes 8 are not connected to the outside air, so that the air inside the air cassettes 8 can be referred to as standing.

Patentanspruch: Wandmauerwerk für Tunnelöfen, mit einer äußeren Verblendwand, einer inneren gemauerten Schamottewand und einer zwischen diesen Wänden angeordneten Isolierwand, d a d u reh g e k e n nz ei eh ne t, daß die Schamottewand (3) aus in einem Abstand (x) voneinander angeordneten Einzelwänden (3a und 3b) besteht, die durch vertikal verlaufende Stege (7) aus Schamottesteinen (6) miteinander verbunden sind, so daß sich Luftkassetten (8) bilden, die vertikal in der Schamottewand (3) verlaufen.Claim: Wall masonry for tunnel kilns, with an outer facing wall, an inner brick fireclay wall and one between these walls Isolation wall, d u g e k e n nz eh ne t that the fireclay wall (3) is made of consists of individual walls (3a and 3b) arranged at a distance (x) from one another, which are connected to one another by vertically extending webs (7) made of firebricks (6) are so that air cassettes (8) are formed, which are vertically in the fireclay wall (3) get lost. Die Erfindung betrifft ein Wandmauerwerk für Tunnelöfen, mit einer äußeren Verblendwand, einer inneren gemauerten Schamottewand und einer zwischen diesen Wänden angeordneten Isolierwand. The invention relates to a wall masonry for tunnel kilns, with a outer facing wall, an inner brick fireclay wall and one between these walls arranged insulating wall. Bei den bekannten Tunnelöfen besteht das Wandmauerwerk aus einer äußeren Verblendwand, einer inneren Schamottewand und einer zwischen diesen Wänden angeordneten Isolierwand. Die innere Schamottewand wird dabei aus Schamottesteinen erstellt, die in massiver Bauweise aufeinander gemauert werden. In the known tunnel kilns, the wall masonry consists of one outer facing wall, an inner fireclay wall and one between these walls arranged insulating wall. The inner fireclay wall is made from firebricks created, which are bricked on top of each other in massive construction. Da diese massive Schamottewand einen ungenügenden Isolierwert besitzt, ist der Wärmefluß vom inneren des Tunnelofens in Richtung der Verblendwand entsprechend groß. Dies hat einen ungünstigen Einfluß auf die Wärmespeicherfähigkeit der Schamottewand. Um den Wärmefluß einzudämmen und somit die Wärmespeicherfähigkeit der Schamottewand anzuheben, ist eine Isolierwand erforderlich, die entweder aus einer hochwertigen Isoliermasse oder aus einer entsprechend dicken Isolierung bestehen muß. In beiden Fällen muß ein nicht geringer Aufwand getrieben werden.Since this massive fireclay wall has an insufficient insulation value, the heat flow from the inside of the tunnel furnace in the direction of the facing wall is corresponding great. This has an unfavorable influence on the heat storage capacity of the fireclay wall. To curb the flow of heat and thus the heat storage capacity of the fireclay wall an insulating wall is required, either of high quality Isolation compound or must consist of a suitably thick insulation. In both In cases, no small effort has to be made. Die Aufgabe der Erfindung besteht nun darin, die Schamottewand so auszubilden, daß diese eine bessere Wärmespeicherfähigkeit erhält und somit die Isolierwand entsprechend dünn gehalten werden kann. The object of the invention is now to make the fireclay wall so train that this receives a better heat storage capacity and thus the Isolation wall can be kept thin accordingly. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schamottewand aus in einem Abstand voneinander angeordneten Einzelwänden besteht, die durch vertikal verlaufende Stege aus Schamottesteinen miteinander verbunden sind, so daß sich Luftkassetten bilden, die vertikal in der Schamottewand verlaufen. This object is achieved according to the invention in that the fireclay wall consists of individual walls arranged at a distance from one another, which are separated by vertically running webs made of firebricks are connected to one another, so that air cassettes form, which run vertically in the fireclay wall. Die Luftkassetten, die mit der Außenluft nicht in Verbindung stehen, wirken dem Wärmefluß von innen nach außen entgegen, da nur über die Stege die Wärme abgeleitet wird. Die Stege bilden Engpässe, wo sich die Wärme staut, d. h. die Wärme wird in der zum Innern des Tunnelofens weisenden Einzelwand gespeichert und wird nur in geringer Menge abgeleitet. Die Wärmespeicherfähigkeit der erfindungsgemäßen Schamottewand hat sich also erhöht. The air cassettes, which are not in contact with the outside air, counteract the flow of heat from the inside to the outside, since the heat only passes through the webs is derived. The webs form bottlenecks where the heat accumulates, i. H. the heat is and is stored in the single wall facing the inside of the tunnel oven derived only in small quantities. The heat storage capacity of the invention Fireclay wall has therefore increased. Durch die erfindungsgemäße Schamottewand wird außerdem der Isolierwert bedeutend gehoben, so daß beim Bau der Isolierwand weniger hochwertige Isoliermasse verwandt oder die Stärke der Isolierwand verringert werden kann. Materialersparnisse sind die unmittelbaren Folgen. The firebrick wall according to the invention also increases the insulation value significantly raised, so that less high-quality insulating compound when building the insulating wall used or the thickness of the insulating wall can be reduced. Material savings are the immediate consequences. Materialersparnisse treten aber auch bei der Schamottewand selbst auf, da durch die Anordnung der Luftkassetten eine erhebliche Anzahl Schamottesteine eingespart wird. However, material savings are also made with the fireclay wall itself because of the arrangement of the air cassettes a considerable number of firebricks is saved. Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigt F i g. 1 eine Ansicht des Wandmauerwerkes in Richtung auf die Schamottewand. The invention is illustrated below with reference to one in the drawing Embodiment explained in more detail. In the drawing, F i g. 1 a view of the wall masonry in the direction of the firebrick wall. Fig. 2 einen Schnitt durch das in Fig. 1 dargestellte Wandmauerwerk entsprechend der Linie II bis 11. FIG. 2 shows a section through the wall masonry shown in FIG. 1 according to line II to 11. Das Wandmauerwerk 1 eines Tunnelofens besteht aus einer den Tunnel (Ofenkanal) 2 begrenzenden Schamottewand 3, einer nachfolgend angeordneten Isolierwand 4 aus mehreren Isolierschichten und einer der Außenluft zugekehrten Verblendwand 5. The wall masonry 1 of a tunnel kiln consists of a tunnel (Furnace duct) 2 delimiting fireclay wall 3, a subsequently arranged insulating wall 4 made of several layers of insulation and a facing wall facing the outside air 5. Die Schamottewand 3 wird aus einzelnen Schamottesteinen 6 aufgemauert, und zwar derart, daß Einzelwände 3a und 3b entstehen, die in einem gewissen Abstand x voneinander angeordnet sind. The firebrick wall 3 is built up from individual firebricks 6, in such a way that individual walls 3a and 3b arise, which are at a certain distance x are arranged from each other. Die Einzelwände 3a und 3b sind durch vertikal verlaufende Stege 7 aus Schamottesteinen 6 miteinander verbunden, so daß sich Luftkassetten 8 bilden, die durch die Stege 7 voneinander getrennt sind. The individual walls 3a and 3b are formed by vertically extending webs 7 of firebricks 6 connected to one another, so that air cassettes 8 are formed, which are separated from one another by the webs 7. Die Sehamotteseine 6 in den Stegen 7 sind so gemauert, daß sie abwechselnd von Schicht zu Schicht mit den Köpfen in die Einzelwand 3a oder 3b eingreifen. The Sehamotteseine 6 in the webs 7 are bricked so that they alternate Engage the individual wall 3a or 3b with their heads from layer to layer. Die Einzelwände 3a und 3b besitzen daher eine gute Standfestigkeit.The individual walls 3a and 3b therefore have good stability.
