Description

Die Erfindung betrifft einen Tunnelofen mit Transportvorrichtung, auf die das Brenngut auflegbar und durch den Ofen transportierbar ist. The invention relates to a tunnel kiln Transport device on which the kiln can be placed and can be transported through the oven.

Um den Durchsatz und die Energieausnutzung zu optimieren ist es erforderlich, den Ofen möglichst gut innen und nach aussen abzudichten. To optimize throughput and energy efficiency it is necessary to place the oven as well inside and behind as possible to seal outside.

Der Spalt zwischen Brenngut und Decke lässt sich durch an der Decke angehängte auf dem Gut schleifende gebogene Bleche erreichen. Ähnliche Konstruktionen sind zwischen Brenngut und Ofenwänden ausführbar. Schwieriger gestaltet sich die Abdichtung nach unten, d. h. nach aussen hin. Hier muß der Tunnelwagen mit Rädern durch andere Transportvorrichtungen ersetzt werden. The gap between the firing material and the ceiling can be opened by the curved one that hung from the ceiling was dragging Reach sheet metal. Similar constructions are between Firing material and furnace walls can be executed. Made more difficult the seal is down, d. H. outwardly. Here must the tunnel car with wheels through other transport devices be replaced.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine einfache Transportvorrichtung im Rahmen des Tunnelofens zu schaffen, welche hinsichtlich der Abdichtbarkeit vorzügliche Eigenschaften aufweist. Diese Aufgabe wird durch folgende Merkmale gelöst:
eine Auflage aus beabstandeten Siliziumkarbid-Stäben oder Spezialschamottestäben, die beidseitig im Ofen in Halterungsblöcken angeordnet sind,
durch seitliche Bahnen auf denen die Halterungsblöcke in Ofenlängsrichtung gleitend und/oder rollend bewegbar sind und
eine Schubvorrichtung am Ofeneingang, die über die jeweils am Ofeneingang befindlichen Halterungsblöcke den Gesamtvorschub des Brenngutes bewirkt. The object of the present invention is to provide a simple transport device in the context of the tunnel furnace, which has excellent properties with regard to sealability. This task is solved by the following features:
a support made of spaced silicon carbide rods or special refractory rods, which are arranged on both sides in the furnace in mounting blocks,
by lateral tracks on which the mounting blocks can slide and / or roll in the longitudinal direction of the furnace and
a pusher at the furnace entrance, which causes the total feed of the firing material via the mounting blocks located at the furnace entrance.

Auf diese Weise lässt sich ein Tunnelofen schaffen, bei dem z. B. die Rauchgase mit hohem Zug durch das Brenngut gezogen werden können, ohne das es zu Kurzschlüssen kommt Damit ist ein optimaler Wärmeübergang vom Rauchgas zum Brenngut, z. B. Lochziegel, insbesondere im Bereich der Vorwärmzone möglich. Ferner ist durch die gewählte Konstruktion auch Unterfeuer möglich. In this way, a tunnel kiln can be created the z. B. the flue gases with a high draft through the kiln can be drawn without short-circuits This is an optimal heat transfer from the flue gas to Brenngut, z. B. perforated brick, especially in the area of Preheating zone possible. Furthermore is chosen by the Construction also possible under fire.

Um die Reibung zwischen den Gleitbahnen und den aneinandergrenzenden Halterungsblöcken zu vermindern können die plan geschliffenen Gleitflächen noch mit einer passenden z. B. aufgedampften Beschichtung versehen sein. To reduce the friction between the slideways and the to reduce adjacent mounting blocks you can still use the flat ground sliding surfaces a matching z. B. vapor-deposited coating his.

Ferner ist es von Vorteil, die Gleitbahnen am Ofeneingang und/oder Ofenausgang durch Rollen zu ersetzen. It is also advantageous to have the slideways at the furnace entrance and / or furnace exit to be replaced by rollers.

Alternativ kann auch die Verwendung von Kugeln in den Bahnen sehr vorteilhaft sein. Alternatively, the use of balls in the Pathways can be very beneficial.

Anhand einer Zeichnung sei die Erfindung näher erläutert; es zeigen: The invention will be explained in more detail with reference to a drawing; show it:

Fig. 1 einen Längsschnitt durch den Ofen, Fig. 1 a longitudinal section through the furnace,

Fig. 2 einen Querschnitt, Fig. 2 shows a cross-section,

Fig. 3, 4 Details der Transportvorrichtung und Fig. 3, 4, details of the transport device and

Fig. 5 einen Transport mit Kugeln und Fig. 5 a transport with balls and

Fig. 6, 7 Transportrollen. Fig. 6, 7 transport rollers.

Das Brenngut 5 wird mit einer Transportvorrichtung in Richtung des Pfeiles 4 durch den Tunnelofen geführt, der im wesentlichen aus Vorwärmzone 1, Brennzone 2 und Kühlzone 3 besteht. Die Abmessungen betragen z. B. ca. 2 m Ofenbreite, 1 m Höhe und 40 m Länge. The firing material 5 is guided with a transport device in the direction of arrow 4 through the tunnel furnace, which essentially consists of preheating zone 1 , firing zone 2 and cooling zone 3 . The dimensions are z. B. approx. 2 m furnace width, 1 m height and 40 m length.

Die Auflage für das Brenngut 5 besteht aus beabstandeten Siliziumkarbid-Stäben 7, die in Halterungsblöcken 6 aus z. B. Keramik angeordnet sind. Die Stäbe sind dabei längsbeweglich gelagert. Die aneinandergrenzenden Halterungsblöcke sind auf zwei seitlichen Gleitbahnen 14 in Ofenlängsrichtung verschiebbar. Hierzu ist eine am Ofeneingang zwischen zwei Toren 11, 12 angeordnete hydraulische Schubvorrichtung 13 vorgesehen, die jeweils über die am Ofeneingang befindlichen Halterungsblöcke 6 den Gesamtvorschub bewirkt. The support for the material 5 is composed of silicon carbide spaced bars 7 made of, in support blocks. 6 B. ceramics are arranged. The rods are mounted to move longitudinally. The adjoining mounting blocks can be moved on two lateral slideways 14 in the longitudinal direction of the furnace. For this purpose, a hydraulic thrust device 13 is provided at the furnace entrance between two gates 11 , 12 , which in each case effects the overall feed via the mounting blocks 6 located at the furnace entrance.

Zur weiteren Abdichtung sind zwischen den Ofenwänden 19 und zwischen der Ofendecke 20 und dem Brenngut 5 schleifende Bleche 16, 17 vorgesehen. Um eine unkontrollierte Strömung unterhalb der Ablage zu verhindern sind Querschotten 18 vorgesehen. For further sealing, grinding plates 16 , 17 are provided between the furnace walls 19 and between the furnace ceiling 20 and the firing material 5 . In order to prevent an uncontrolled flow below the shelf, transverse bulkheads 18 are provided.

Auf diese Weise lassen sich die Rauchgase entgegen der Transportrichtung weitgehend durch das Brenngut ziehen und somit deren Wärmeenergie optimal ausnutzen. In this way, the flue gases can be counteracted Pull the transport direction largely through the firing material and thus make optimal use of their thermal energy.

Die Rauchgase gelangen dann zum Kamin und/oder in die Kühlzone. The flue gases then reach the chimney and / or the Cooling zone.

Eine weitere brenntechnische Verbesserung ergibt sich durch die zusätzliche Möglichkeit von Unterfeuer, wie durch den Brenner 15 angedeutet. A further improvement in terms of combustion results from the additional possibility of underfire, as indicated by burner 15 .

Die Gleitbahnen, z. B. aus geschliffener Schamotte bestehend sind aus etwas härterem Material als die Halterungsblöcke, da diese leichter austauschbar sind. The slideways, e.g. B. consisting of ground chamotte are made of somewhat harder material than the mounting blocks, because these are easier to replace.

Die Halterungsblöcke 6 sind auf den seitlichen Gleitbahnen 14 geführt (vgl. Fig. 4). The mounting blocks 6 are guided on the lateral slideways 14 (cf. FIG. 4).

Um die Reibung zu verringern können die Gleitbahnen am Ofeneingang und/oder Ofenausgang bis zu ca 500°C durch beabstandete Stahlrollen 28 relativ kleinen Durchmessers ersetzt werden (Fig. 6). Damit kann jeder Halterungsblock auf mehreren Rollen aufliegen. Die Rollen können mit einer Führung 27 für die Halterungsblöcke versehen sein (Fig. 7). In order to reduce the friction, the slideways at the furnace entrance and / or furnace exit can be replaced by spaced steel rollers 28 of relatively small diameter up to approximately 500 ° C. ( FIG. 6). This means that each bracket block can rest on several rollers. The rollers can be provided with a guide 27 for the mounting blocks ( Fig. 7).

Wie in Fig. 5 gezeigt, kann die Gleitführung durch eine Kugelführung ersetzt werden. Hierzu werden aneinandergrenzende Kugeln 26 aus Hartkeramik mit z. B. einem Durchmesser von ca. 40 mm in konischen Laufschienen 21 der seitlichen Bahnen 24 geführt. Die darauf verschiebaren Halterungsblöcke 25 für die SiC-Stäbe sind mit entsprechend angepassten Führungen 23 versehen. As shown in Fig. 5, the slide guide can be replaced with a ball guide. For this purpose, adjacent balls 26 made of hard ceramic with z. B. a diameter of about 40 mm in conical rails 21 of the lateral tracks 24 . The mounting blocks 25 for the SiC rods which can be shifted thereon are provided with correspondingly adapted guides 23 .

Zur Verminderung des Abriebes können in die Laufschienen 21 SiC-Platten 22 oder dergl. eingelegt sein. In order to reduce the abrasion, SiC plates 22 or the like can be inserted into the running rails 21 .

Anstelle je einer seitlichen Laufschiene können auch zwei oder mehre parallele Laufschienen vorgesehen sein. Instead of one side track each, two or several parallel tracks are provided.

Die Kugeln können vom Ende des Ofens selbsttätig zurückgeführt und gereinigt werden. The balls can be automatically returned from the end of the furnace and be cleaned.

Ergänzend sei noch bemerkt, daß die SiC Stäbe ggf. auch durch Stäbe aus anderer geeigneter Hartkeramik ersetzt werden und die Kugelführungen zu Kugelbetten erweitert werden können. In addition, it should also be noted that the SiC rods may also pass through Rods made of other suitable hard ceramics are replaced and the Ball guides can be expanded to ball beds.
