Description

Die Erfindung bezieht sich nach dem Oberbegriff des Hauptanspruches auf ein Verfahren zum Brennen von Keramik o. dgl. Brenngut in einem periodisch arbeitenden Ofen und schließt eine Anordnung zur Durchführung des Verfahrens unter Nutzung eines Herdwagenofens ein.According to the preamble of the main claim, the invention relates to a method for firing ceramic or the like. Firing material in a periodically operating furnace and includes an arrangement for carrying out the method using a bogie hearth furnace.

Bisher bekannte periodische Brennöfen, wie Elevator-Schnellbrandofen, Großraum-Herdwagenofen oder Großraum-Kammerofen, weisen noch einen großen Wärmeverlust auf, der durch die relativ lange Öffnungszeit der großen Ofentore beim Besatzwechsel des Ofens entsteht. Das Einfahren der Brennpaletten mit Hubwagen bzw. Gabelstapler in den Brennraum birgt weiterhin ein Risiko bezüglich von Bruch des Brenngutes in sich. Die bisher bekannten Herdwagenöfen bzw. sogenannten Hauben-Öfen verbessern zwar die benötigte Handlingzeit beim Besatzwechsel der Öfen; hinsichtlich des Energiebedarfes sind jedoch insbesondere unter Beachtung der immer bedeutsameren Umweltentlastung weitere Verbesserungen notwendig und von den Anlagenanwendern gefragt.
Die Aufgabe der Erfindung besteht nun darin, ein neuartiges Verfahren zum Brennen von Keramik o. dgl. Brenngut in einem periodisch arbeitenden Ofen sowie eine Anordnung zur Durchführung des Verfahrens zu schaffen, das einen verringerten Energieverlust gewährleistet, mit geringem technisch-ökonomischen Aufwand herstellbar ist und als System-Baustein in eine Fertigungslinie für Keramikteile o. dgl. integrierbar ist.
Previously known periodic kilns, such as elevator rapid firing kilns, large-scale bogie hearth furnaces or large-chamber kilns, still show a great heat loss, which is caused by the relatively long opening time of the large furnace doors when the furnace is changed. Moving the firing pallet into the firing chamber with a pallet truck or forklift still poses a risk of the firing material breaking. The previously known bogie hearth furnaces or so-called hood furnaces improve the handling time required when changing the furnaces; With regard to the energy requirement, however, further improvements are necessary, especially in consideration of the increasingly significant environmental relief, and are requested by the system users.
The object of the invention is to provide a novel method for firing ceramic or the like. Firing material in a periodically operating furnace and an arrangement for carrying out the method, which ensures reduced energy loss, can be produced with little technical and economic effort and can be integrated as a system component in a production line for ceramic parts or the like.

Diese Aufgabe löst erfindungsgemäß ein Verfahren nach dem Oberbegriff des Patentanspruches 1 durch die kennzeichnenden Merkmale in Verbindung mit einer Anordnung zur Durchführung des Verfahrens. Die nachgeordneten Ansprüche offenbaren Weiterbildungen und vorteilhafte Ausführungsvarianten des Verfahrens und der Anordnung.
Dieses erfindungsgemäße Verfahren und die Anordnung zur Durchführung ermöglichen einen modernen Ofenbau, der im Fertigungs-Prozeß einen geringeren Energieverbrauch, kurze Handlingszeiten, einen großen Brenngut-Durchsatz, einen zügigen Materialfluß und einen geringeren technisch-ökonomischen Aufwand beim Bau dieser Öfen garantiert.
This object is achieved according to the invention by a method according to the preamble of claim 1 by the characterizing features in connection with an arrangement for carrying out the method. The subordinate claims disclose further developments and advantageous embodiment variants of the method and the arrangement.
This method according to the invention and the arrangement for carrying out enable a modern furnace construction, which guarantees a lower energy consumption, short handling times, a large throughput of firing material, a rapid material flow and a lower technical-economic effort in the construction of these furnaces in the manufacturing process.

Folgend wird die Erfindung anhand von in Zeichnungen schematisiert dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:

Unter Heranziehung der Figuren 1 - 3a wird nun erst einmal das grundsätzlich Neue des für den modernen Ofenbau bahnbrechenden erfindungsgemäßen Verfahrens sowie der zur Durchführung des Verfahrens konzipierten Anordnung beschrieben.
Die mit Brenngut beladenen Brennregale 13 werden auf einer dem Ofen 1 vorgelagerten Rampe 16 zu einer Brenncharge zusammengestellt. Das dieser Rampe 16 zugewandte Ofentor 2 des Ofen 1 öffnet hier durch seitliche Verschiebung die Brennkammer 1a, wobei zuvor der Ofenboden 6 etwas angehoben wurde.
Danach fährt der den Ofenboden 6 tragende Herdwagen 8 unter die Rampe 16, übernimmt hier 16 die Charge von Brennregalen 13 mittels einem auf der Oberseite des Ofenbodens 6 vorgesehenen Distanzgestelles 12, welches 12 mitsamt dem Ofenboden 6 entsprechend angehoben wird, und fährt dann zurück in die Brennkammer 1a. Das Ofentor 2 wird nun unverzüglich an den Ofen 2 herangeschoben und der Ofenboden 6 mit den darauf befindlichen Brennregalen 13 abgesenkt; anschließend erfolgt der Brennvorgang.
Nach dem Brennvorgang wird der Ofenboden 6 wieder angehoben, das gegenüberliegende Ofentor 3 geöffnet und der Herdwagen 8 fährt nun zur Rampe 19, auf der die Brennregale 13 mit dem gebrannten Brenngut abgestellt werden. Unverzüglich nach dem Abstellen der gebrannten Charge fährt der Herdwagen 8 durch die Brennkammer 1a hindurch zur Rampe 16, um dort eine neue Brenncharge aufzunehmen und plaziert diese in vorher beschriebener Weise in der Brennkammer. Die Ofentore 2 und 3 werden bei diesem Arbeitsschritt des Be- und Entladens, dem Besatzwechsel, für das Ein- und Ausfahren des Herdwagen 8 entsprechend geöffnet und geschlossen.
Using FIGS. 1-3, the fundamentally new aspect of the method according to the invention which is groundbreaking for modern furnace construction and the arrangement designed to carry out the method will now be described.
The firing racks 13 loaded with firing material are assembled into a firing batch on a ramp 16 upstream of the furnace 1. The furnace gate 2 of the furnace 1 facing this ramp 16 opens the combustion chamber 1a here by lateral displacement, the furnace base 6 having previously been raised somewhat.
Thereafter, the bogie car 8 carrying the furnace floor 6 moves under the ramp 16, here 16 takes over the batch of firing racks 13 by means of a spacer frame 12 provided on the top of the furnace floor 6, which 12 together with the furnace floor 6 is raised accordingly, and then moves back into the combustion chamber 1a. The furnace gate 2 is now immediately pushed towards the furnace 2 and the furnace floor 6 with the firing racks 13 located thereon is lowered; then the burning process takes place.
After the firing process, the furnace floor 6 is raised again, the opposite furnace gate 3 is opened and the bogie car 8 now moves to the ramp 19, on which the firing racks 13 with the fired firing material are placed. Immediately after the burned batch has been switched off, the bogie car 8 travels through the combustion chamber 1a to the ramp 16 in order to receive a new combustion batch there and places it in the combustion chamber in the manner previously described. In this step of loading and unloading, changing the trimmings, the furnace gates 2 and 3 are opened and closed accordingly for the entry and exit of the bogie carriage 8.

Es ist auch im Sinne der Erfindung, die Ofentore 2 und 3 bei herausgefahrenem Herdwagen 8 zwischenzeitlich wieder zu schließen, wobei diese Verfahrensweise unter dem Blickfeld der Dimensionierung des Gesamt-Brennsystems wahlweise angewendet werden kann.It is also within the scope of the invention to temporarily close the oven gates 2 and 3 again when the bogie wagon 8 is moved out, this procedure being able to be used selectively in view of the dimensioning of the overall firing system.

Zur Führung des Herdwagens 8 verläuft eine Herdwagenführung 15 von der Rampe 16 unter den Ofen 1 hindurch bis zur Rampe 19.
Zur Höhenverstellung des auf dem Herdwagen 8 angeordneten Ofenbodens 6 ist zwischen dem Unterteil 9 und dem Oberteil 10 des Herdwagens 8 mindestens eine Hubeinheit 12 vorgesehen.
In einer Weiterbildung der Erfindung ist das Oberteil 10 des Herdwagens 8 gleichzeitig als Ofenboden 6 ausgebildet.
To guide the bogie carriage 8, a bogie carriage guide 15 runs from the ramp 16 under the furnace 1 to the ramp 19.
To adjust the height of the furnace base 6 arranged on the bogie car 8, at least one lifting unit 12 is provided between the lower part 9 and the upper part 10 of the bogie car 8.
In a development of the invention, the upper part 10 of the hearth trolley 8 is simultaneously designed as a furnace floor 6.

Damit eine zugluftfreie Abdichtung der Brennkammer 1a gegeben ist, sind die Ofentore 2 und 3, die Ofenseitenwände 17 und 18 und der Ofenboden 6 sowie der später näher beschriebene weitere Ofenboden 22 mit aufeinander abgestimmten profilierten Rändern 2a bzw. 3a, 17a, 18a versehen und die beiden Ofenböden 6 und 22 weisen jeweils einen umlaufenden, nach unten gerichteten Rand 7 auf.
Durch diese neuartige Dichtmethode der Herdwagenöfen entfallen aufwendige Konstruktionen wie Sandrinnen und zwischengelagerte Dichtprofile (-balken); beim Öffnen des Ofenbodens zur Unterstützung der Kühlphase kann durch den auftretenden Luftstrom kein Sand mitgerissen werden und weiterhin ist der Kühlprozeß definierter beeinflußbar.
So that a draft-free seal of the combustion chamber 1a is provided, the furnace gates 2 and 3, the furnace side walls 17 and 18 and the furnace floor 6 and the further furnace floor 22 described later are provided with coordinated profiled edges 2a and 3a, 17a, 18a and that Both furnace floors 6 and 22 each have a peripheral, downward edge 7.
This new sealing method for the bogie hearth furnaces eliminates the need for complex constructions such as sand channels and intermediate sealing profiles (beams); When the furnace floor is opened to support the cooling phase, no sand can be entrained by the air flow and the cooling process can also be influenced in a more defined manner.

Zur Entfeinerung von Fertigungstoleranzen ist die Einlage eines vorzugsweise am Ofenboden 6 bzw. 22 befestigten, unprofilierten Dichtmaterials zwischen den Rändern 2a, 3a, 17a, 18a und 7 möglich. Das Gewicht des Ofenbodens 6 bewirkt ein luftdichtes Schließen.In order to refine manufacturing tolerances, it is possible to insert an unprofiled sealing material, preferably fastened to the furnace base 6 or 22, between the edges 2a, 3a, 17a, 18a and 7. The weight of the furnace base 6 causes an airtight closure.

Die Fig. 4 - 4b zeigen in geschnittenen Ansichten die Ausstattung eines Ofen 1 mit bodenseitigen Abgasabzügen 21, die gleichzeitig mit dem Absenken des die Brennkammer 1a schließenden Ofenbodens 6 formschlüssig an die Abgasfüchse 23 anschließen.4 - 4b show a sectional view of the equipment of a furnace 1 with exhaust flues 21 on the bottom, which at the same time as the furnace bottom 6 closing the combustion chamber 1 a form-fittingly connect to the exhaust fumes 23.

Die in den Fig. 1 - 3a dargestellte Ausführungsvariante des Ofen 1 ist dagegen mit in der Ofendecke 4 vorgesehenen Abgasabzügen 5 versehen.The embodiment variant of the furnace 1 shown in FIGS. 1-3a, on the other hand, is provided with exhaust fumes 5 provided in the furnace ceiling 4.

In einer nicht dargestellten Weiterbildung der Erfindung wird die die gebrannte Charge zwischenzeitlich lagernde Rampe 19 neben der bereitstellenden Rampe 16 angeordnet und die Rampe 16 bzw. 19 jeweils wechselnd über der Herdwagenführung 15 positioniert. Die Anwendung dieser Ausgestaltungsvariante ist von der kundenbezogenen, gesamten baulichen Anlagenkonzeption abhängig.In a further development of the invention, which is not shown, the ramp 19 temporarily storing the fired batch is arranged next to the providing ramp 16 and the ramp 16 or 19 is positioned alternately above the bogie carriage guide 15. The application of this design variant depends on the customer-related, overall structural system design.

Eine weitere Ausgestaltung des erfinderischen Grundgedankens besteht darin, in Abhängigkeit von Größe und Form des Brenngutes die Brennregale mit höhenverstellbaren Regalböden auszustatten und unter Beachtung des Gesamtgewichtes der Brenncharge mehrere Hubeinheiten am Herdwagen 8 vorzusehen und im Bedarfsfall zusätzlich den Ofenboden 6 bzw. 22 in mehrere Segmente zu unterteilen.A further embodiment of the basic idea of the invention consists in equipping the firing racks with height-adjustable shelves depending on the size and shape of the firing material and, taking into account the total weight of the firing batch, to provide several lifting units on the bogie car 8 and, if necessary, the furnace floor 6 or 22 in several segments divide.

Darüber hinaus ist durch das beschriebene neuartige Brennverfahren und der zugeordneten Anordnung mit den besagten Weiterbildungen die beste Voraussetzung gegeben, einen derartig gestalteten Fertigungsabschnitt - Brennen - teil- oder vollautomatisiert aufzubauen und zudem einen solchen Brenn-Fertigungsabschnitt in eine zumindest teilweise automatisierte Fertigungsstraße für Keramikteile o. dgl. Produkte zu integrieren.In addition, the novel firing method described and the associated arrangement with the said developments provide the best prerequisite for partially or fully automated construction of such a manufacturing section - firing - and also such a firing manufacturing section in an at least partially automated production line for ceramic parts or. Like to integrate products.

Ein positiver Effekt anderer Art besteht nun noch darin, den ohnehin vorgesehenen Arbeitstakt - Heben des Ofenbodens 6 bzw. 22 - in den zum Brennvorgang gehörigen Arbeitstakt - Abkühlen - einzubinden oder auch darin, die Brennregale 13 innerhalb der gesamten Fertigungsstraße einzusetzen, wodurch das Umlagern des Brenngutes vor und nach dem Brennen entfällt.

Figure imgb0001
A positive effect of another kind is now to include the already provided work cycle - lifting the furnace base 6 or 22 - in the work cycle associated with the firing process - cooling - or also to use the firing racks 13 within the entire production line, thereby relocating the Fired goods before and after firing are not required.
