Abstract

The transport device has bars accommodating the material which run crossways to the conveyor direction of the transport device. The bars penetrate slots in the side walls of the combustion chamber and the combustion chamber itself and at both ends are supported by interconnected rail-guided retainers. The retainers are tightly arranged in the slot area, thereby sealing the slots. The retainers (9) with the bars (7) in the end area of the combustion chamber (1) are removable one after the other with greater speed to the entry area of the combustion chamber where they are connectable with the retainers in the work area (13).

Description

Die Erfindung geht aus von einem Brennofen insb. für keramische Erzeugnisse, bei dem das zu brennende Gut mittels einer Transporteinrichtung durch eine kanalartige Brennkammer hindurchbewegt wird, wobei die Transporteinrichtung das Gut aufnehmende Stäbe aufweist, die quer zur Förderrichtung der Fördereinrichtung verlaufen, Schlitze in den Seitenwänden der Brennkammer und die Brennkammer durchsetzen und von untereinander verbundenen, schienengeführten Halterungen getragen sind, die im Schlitzbereich an einander anschließend angeordnet sind und dabei die Schlitze abdichten.The invention is based on a kiln, in particular for ceramic Products in which the material to be burned by means of a transport device through a channel-like Combustion chamber is moved through, the transport device the well-absorbing rods which are transverse run to the conveying direction of the conveyor, slots in the side walls of the combustion chamber and the combustion chamber enforce and of interconnected, rail-guided Brackets are worn in the slot area are arranged next to each other while doing the Seal the slots.

Derartige Brennöfen sind bekannt ( DE-A- 41 30 437 ), jedoch wird hierbei ein umlaufender Förderer benutzt, der sowohl im Obertrum ( Arbeitstrum ) als auch im Rücktrum die Halterungen mit den von ihnen getragenen Querstäben aufweist. Dies bedeutet, dass der Brennofen eine entsprechend grosse Anzahl der Halterungen und vor allen Dingen aber entsprechend viele Querstäbe benötigt, die allerdings einen hohen Anschaffungspreis bedingen. Such furnaces are known (DE-A-41 30 437), however, a rotating conveyor is used here, that both in the upper run (work run) and in the back run the brackets with the crossbars they carry having. This means that the furnace has a corresponding large number of brackets and above all Things but needed a corresponding number of cross bars however, require a high purchase price.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen und demgemäss zu erreichen, dass die Anzahl der Halterungen mit den von ihnen getragenen Querstäben verringert werden kann.The invention is based on the object To eliminate disadvantages and accordingly achieve that the number of brackets with the ones they carry Cross bars can be reduced.

Zur Lösung dieser Aufgabe sind erfindungsgemäss im Endbereich der Brennkammer die Halterungen mit den Stäben nacheinander entfernbar, mit im Vergleich zum Arbeitstrum vergrösserter Geschwindigkeit zum Eingangsbereich der Brennkammer bewegbar und dort mit den im Arbeitstrum befindlichen Halterungen verbindbar.To solve this problem, according to the invention, are in the end area the brackets with the rods in the combustion chamber can be removed one after the other, compared to the work strand increased speed to the entrance area of the Combustion chamber movable and there with those in the work area existing brackets connectable.

Demgemäss kommt ein umlaufender Förderer in Fortfall, und folglich werden die Halterungen nicht auch im Rücktrum dicht bei dicht geführt, sondern auf dem Wege vom Endbereich der Brennkammer vereinzelt, aber mit qrösserer Geschwindigkeit zur Eingangsstelle der Brennöfen zurückgeführt. Um dabei die Halterungen besser entfernen bzw. an der Eingangsstelle hinzufügen zu können, werden die Halterungen mit ihren Stäben im Arbeitstrum schrittweise geführt, wobei sie vom Endbereich der Brennkammer aus als gezogene Elemente bewegt werden und demgemäss zugfest untereinander in Verbindung stehen müssen.Accordingly, a rotating conveyor comes to an end, and consequently the brackets are not also in the Back run close to each other, but on the way isolated from the end area of the combustion chamber, but with q higher speed to the entry point of the kilns recycled. To make the mounts better remove or add at the entry point to can, the brackets with their rods in Work strand gradually led, being from the end area are moved out of the combustion chamber as drawn elements and are therefore connected to each other in a tensile manner have to.

Während die Halterungen mit ihren Stäben im Arbeitstrum schrittweise geführt sind, kann zur Rückführung der Halterungen vom Endbereich zur Eingangsstelle der Brennkammer eine Mitnahme unter Verwendung eines umlaufenden Förderers z.B. in Form eines Schleppförderers erfolgen.While the brackets with their bars in the working area can be used to return the brackets from the end area to the entry point of the combustion chamber a take-away using a rotating conveyor e.g. in the form of a drag conveyor.

Um die Halterungen hinzufügen bzw. entfernen zu können, werden sie untereinander lösbar verbunden. Dies erfolgt zweckmässigerweise durch eine Haken- bzw. Zapfenverbindung, um so zwischen aufeinander folgenden Halterungen eine zugfeste Verbindung im Arbeitstrum herstellen zu können. To add or remove the brackets, they are releasably connected to each other. this happens expediently by a hook or pin connection, so between successive brackets Establish a tensile connection in the work area can.

  • Fig. 4 is a plan view of the holder according to Fig. 3 and
  • Fig. 5 is a plan view of a modified releasable connection between successive brackets in a schematic representation.

    • In bekannter Weise hat die Brennkammer 1 Seitenwände 2, einen Boden 3 und eine Decke 4. Diese Bestandteile bestehen vorwiegend aus einem wärmeisolierenden Werkstoff. Zum Tragen der Brennkammer dient ein Stahlgerüst mit Stützen 5 und Querträgern 6.In a known manner, the combustion chamber 1 has side walls 2, a floor 3 and a ceiling 4. These components consist predominantly made of a heat-insulating material. A steel frame is used to support the combustion chamber Supports 5 and cross members 6.

    Es sind waagerechte, mit geringem, gegenseitigem Abstand angeordnete Stäbe 7 vorgesehen, die die Brennkammer 1 in ihrem unteren Teil und ferner je einen Schlitz 8 in den Seitenwänden 2 durchsetzen. Die Stäbe 7 sind hohle Vierkantstäbe aus einem wärmefesten Werkstoff und biegesteif ausgeführt. Die Stabenden liegen ausserhalb der Seitenwände 2 und lagern dort in einer blockartigen Halterung 9, die sich ihrerseits auf einem wagenartigen Gestell 10 befindet. Die zugehörigen Räder 11 spuren auf Schienen 12 des Arbeitstrums 13. Unterhalb der Brennkammer 1 befindet sich der Leertrum 14 mit den dort befindlichen Schienen 12.They are horizontal, with a small, mutual distance Arranged rods 7 provided that the combustion chamber 1 in its lower part and also a slot 8 push through in the side walls 2. The bars 7 are hollow Square bars made of a heat-resistant material and resistant to bending executed. The rod ends are outside the side walls 2 and store there in a block-like Bracket 9, which in turn is on a carriage-like Frame 10 is located. The associated wheels 11 track Rails 12 of the work strand 13. Below the combustion chamber 1 there is the empty strand 14 with those located there Rails 12.

    Wie aus Fig. 2 - obere Hälfte - hervorgeht, liegen die Halterungen 9 dichtend aneinander. Wie weiterhin Fig. 1 zeigt, haben die Halterungen 9 eine solche Formgebung, dass sie den Schlitz 8 ausfüllen, um so eine ausreichend gute Schlitzabdichtung herbeiführen zu können.As can be seen from Fig. 2 - upper half -, the Brackets 9 sealing together. As continues Fig. 1st shows, the brackets 9 have such a shape that they fill in the slot 8, so as to be a good enough To be able to bring slot sealing.

    Das auf den Stäben 7 durch die Brennkammer 1 hindurchgeführte Brenngut ist mit 15 bezeichnet, wobei es besonders vorteilhaft ist, dass auf jeder Halterung 9 zwei Paare der Stäbe 7 vorgesehen sind,gegebenenfalls aber auch weitere Stäbe 7 und auch Stäbe 7, die nicht in Paaren vorgesehen sind. Am in Bewegungsrichtung der Gestelle 10 vorderen Ende haben die Gestelle 10 einen Haken 16, der in einen Querbolzen 17 des folgenden Gestelles 10 eingehängt werden kann. Wird so auf das im Arbeitstrum 13 vorne liegende Gestell 10' z.B. durch einen Hydraulikzylinder eine Vorschubbewegung im Sinne des Pfeiles 18 eingeleitet, so folgen alle Anhänger in Form der angehängten Gestelle 10. Diese Vorschubbewegung innerhalb der Brennkammer 1 geschieht somit takt- und schrittweise, und zwar vorzugsweise gerade um das Mass der Länge eines Gestells 10 in der Weise, dass sich am Ende der Brennkammer 1 jeweils ein Gestell 10 ergibt, das - wie bei x dargestellt - durch Kippen nach unten um einen Winkel von etwa 20 - 30 ° nach unten abgezogen werden kann. Dieses freigewordene und selbstverständlich vom Brenngut 15 befreite Gestell 10 wird unten auf die Schiene 12 abgesetzt und dort mit erhöhter Geschwindigkeit zusammen mit der Halterung 9 und den Stäben 7 an die Aufgabestelle des Brennofens in Richtung des Pfeiles 19 geführt.That passed through the combustion chamber 1 on the rods 7 Firing material is designated 15, it being particularly advantageous is that on each bracket 9 two pairs of rods 7 are provided, but optionally also other rods 7 and also bars 7, which are not provided in pairs. At the front end in the direction of movement of the frames 10 the frames 10 have a hook 16 which is in a Cross bolt 17 of the following frame 10 are hooked can. Is so on the front lying in the working section 13 Frame 10 'e.g. a feed movement by means of a hydraulic cylinder initiated in the direction of arrow 18, so follow all trailers in the form of the attached racks 10. This feed movement takes place within the combustion chamber 1 thus step by step and step by step, preferably straight by the measure of the length of a frame 10 in such a way that at the end of the combustion chamber 1 there is a frame 10, this - as shown at x - by tilting it down subtract an angle of about 20 - 30 ° downwards can. This freed up and of course from Firing frame 15 freed frame 10 is below on the rail 12th deposed and there together at increased speed with the bracket 9 and the rods 7 to the drop point of the kiln in the direction of arrow 19.

    Dort wird das Gestell 10 angehoben und in einer Schrägstellung ( unter einem Winkel von etwa 20 - 30° schräg nach oben zeigend ) von oben in den Querbolzen 17 eingehängt. Hat das Gestell 1o seine waagerechte Stellung eingenommen, so ist die zugfeste Verbindung hergestellt,und die Beschickung der Stäbe 7 kann vollzogen werden.There the frame 10 is raised and in an inclined position (at an angle of about 20 - 30 ° upwards pointing) hooked into the cross bolt 17 from above. Has the Frame 1o has taken its horizontal position, that is the tensile connection established, and the loading of the Bars 7 can be executed.

    Das Verfahren der Gestelle 10 im Sinne des Pfeiles 19 kann an sich beliebig erfolgen; vorzugsweise wird jedoch ein umlaufender Förderer, insb. ein Kettenförderer benutzt; er sollte auch taktweise betrieben werden, um das Aufsetzen und das Abziehen der Gestelle 10 erleichtert durchführen zu können.The process of frames 10 in the direction of arrow 19 can be done in any way; but is preferred a revolving conveyor, esp. a chain conveyor used; it should also be operated intermittently to touchdown and pulling off the racks 10 makes it easier to perform can.

    Wichtig ist es auch, dass eine Umkehr der Gestelle 10 zum Rücktransport nicht stattfindet; die Haken 16 zeigen also stets in die Richtung gemäss Pfeil 18.It is also important that the frames 10 are reversed does not take place for return transport; the hooks 16 show always in the direction of arrow 18.

    Bei der Ausführung gemäss Fig. 3 wird nicht ein starr befestigter Haken 16 benutzt,sondern ein um eine waagerechte Achse 20 verschwenkbarer, mit Gegengewicht und Schwenkhebel 21 ausgestatteter Haken 22, der im Endbereich der Brennkammer 1 auf einen Nocken 23 auflaufen kann, um so den Haken 22 anzuheben. In dieser Hakenstellung kann das abzukoppelnde Gestell 10 ohne weiteres in Richtung des Pfeiles 18 abgezogen werden, ohne also dazu eine Kippbewegung herbeiführen zu müssen. Es sei erwähnt, dass natürlich der bei y dargestellte Haken 22 dem vorne liegenden, nicht dargestellten Gestell 10 zugehört.3 is not a rigidly attached Hook 16 used, but one around a horizontal Axis 20 swiveling, with counterweight and swivel lever 21 equipped hook 22, which in the end region of the combustion chamber 1 can run onto a cam 23 so as to raise the hook 22. In this hook position, the frame 10 to be decoupled can are easily subtracted in the direction of arrow 18, without having to bring about a tilting movement. It should be mentioned that of course the hook 22 shown at y listened to the front frame 10, not shown.

    Die Ausführung gemäss Fig. 5 zeigt abgeänderte Möglichkeiten des Ab- und Einkuppelns eines Gestells 10. Hier ist an einem Vorsprung 24, der vorzugsweise beidseitig am Gestell 10 anzuordnen ist, ein quer verlaufender Zapfen 25 angeordnet, der in eine entsprechende Ausnehmung eines Vorsprungs 26 des benachbarten Gestelles 10 eingreifen kann. Das abzukoppelnde bzw. anzukoppelnde Gestell 10 kann hierbei durch eine Querbewegung des abzukoppelnden bzw. anzukoppelnden Gestells 10 in Wirkstellung bzw. ausser Wirkstellung gebracht werden.5 shows modified options the coupling and uncoupling of a frame 10. Here is one Projection 24, which is preferably on both sides of the frame 10 is to be arranged, a transverse pin 25 is arranged, which in a corresponding recess of a projection 26th of the adjacent frame 10 can intervene. That to be uncoupled or to be coupled frame 10 can by a Transverse movement of the frame 10 to be uncoupled or coupled be brought into active position or out of active position.

    Die erfindungsgemässe Ausbildung des Brennofens hat den grossen Vorteil, dass eine wesentlich verringerte Anzahl der Halterungen 9 und der Stäbe 7 ausreichend ist, um einen ordnungsgemässen Brennbetrieb durchführen zu können.The inventive design of the kiln has the great advantage that a significantly reduced number of Mounts 9 and the rods 7 is sufficient to one to be able to carry out proper burning operations.

    Es sei erwähnt, dass die Stäbe 7 mit ihren Enden auswechselbar in Lagerstellen bzw. Durchgangslöchern der die Schlitzabdichtung bewirkenden Halterungen 9 angeordnet sind.It should be mentioned that the ends of the rods 7 are interchangeable in bearing points or through holes of the slot seal effecting brackets 9 are arranged.

    Ferner sei bemerkt, dass die Schrittbewegung der Halterung 9 auch in Abhängigkeit von den Stäben 7, aber auch in Abhängigkeit von dem darauf befindlichen Brenngut 15 erfolgen kann. Die Schrittlänge kann also der Länge der Rasterung der Stäbe 7, aber auch der Länge des Rasters des Brenngutes 15 entsprechen.It should also be noted that the step movement of the holder 9 also depending on the bars 7, but also depending of the firing material 15 located thereon. The stride So can the length of the grid of the rods 7, but also correspond to the length of the grid of the firing material 15.
