Description

Die Erfindung betrifft eine keramische Lochplatte für eine Zustellung eines Feuerungsraumes, insbesondere zur Müll- und/oder Sondermüllverbrennung.The invention relates to a ceramic perforated plate for an infeed Furnace, in particular for waste and / or special waste incineration.

Eine derartige Lochplatte ist in dem DE 296 14 856 U1 beschrieben. Die Lochplatten sind aus einem luftbeaufschlagten Hohlraum hinter den Platten luftgekühlt. Die Lochplatte weist eine Vielzahl von Luftkanäle bildenden Löchern auf, so daß sich vor der Feuerraumseite der Lochplatten ein Luftschleier bildet. Dieser verhindert schon aufgrund der Aerodynamik der Luftströmungen Ablagerungen von Flugasche an der Lochplatte und damit Schlackenanbackungen. Außerdem erfolgt durch die Vielzahl der Löcher eine das gesamte Volumen der Lochplatte erfassende Kühlung. Die Lochplatten sind also nicht nur rückseitig oder an den Rändern gekühlt. Dieser Kühleffekt verlängert die Haltbarkeit der Platten wesentlich.Such a perforated plate is described in DE 296 14 856 U1. The Perforated panels are from an air-filled cavity behind the panels air-cooled. The perforated plate has a multiplicity of air channels Open holes so that there is a front of the firebox side of the perforated plates Air curtain forms. This prevents the aerodynamics of the Air currents deposits of fly ash on the perforated plate and thus Slag caking. In addition, due to the large number of holes cooling covering the entire volume of the perforated plate. The perforated plates are therefore not only cooled on the back or on the edges. This cooling effect extends the shelf life of the panels significantly.

Nach dem DE 296 14 856 U1 sind im Bereich der Ecken der Lochplatten Stufen vorgesehen, an denen die Lochplatten befestigbar sind. Zur Befestigung vorgesehene Schrauben oder sonstige Metallteile müssen vom Feuerungsraum zugänglich sein und korrodieren deshalb in der Atmosphäre des Feuerungsraums schnell. Sie müssen dementsprechend oft ausgewechselt werden. Darüber hinaus ist die Montage bzw. Demontage aufwendig. According to DE 296 14 856 U1 are in the area of the corners of the perforated plates Steps are provided to which the perforated plates can be attached. For fixing Any screws or other metal parts provided must be removed from the combustion chamber accessible and therefore corrode in the atmosphere of the Furnace quickly. Accordingly, they need to be replaced often become. In addition, assembly and disassembly is complex.

In der DE 196 38 711 A1 ist eine Verkleidung der Innenwand eines Brennraumes mit feuerfesten Formsteinen beschrieben, wobei jeder Formstein mit einer Ausnehmung in eine Halterung einhängbar ist, die ein in den Brennraum ragendes Hakenteil und mindestens ein Rohr aufweist. Für Lochplatten nach dem DE 296 14 856 U1 ist diese Halterung nicht geeignet.In DE 196 38 711 A1 is a lining of the inner wall of a Combustion chamber described with refractory shaped stones, each shaped stone can be suspended with a recess in a holder, the one in the Combustion chamber projecting hook part and at least one tube. For Perforated plates according to DE 296 14 856 U1, this holder is not suitable.

Ein Zweischichtstein zur Auskleidung eines Feuerraums einer Glasschmelzanlage ist in der DE 195 43 430 A1 beschrieben. Am Zweischichtstein sind Ausnehmungen zur teilweisen Aufnahme von Rohren der Wandung eines Kesselraums vorgesehen. Zur Aufhängung des Zweischichtsteins weist er Vertiefungen auf, die schräg zur Haupterstreckungsebene verlaufen. Die Vertiefungen dienen zum vertikalen Aufhängen des Zweischichtsteins an Haken. Jede der Vertiefungen erstreckt sich über die gesamte Breite des Zweischichtsteins. Solche Vertiefungen schwächen die Stabilität und sind bei Lochplatten nach dem DE 296 14 856 U1 ungeeignet.A two-layer brick for lining a firebox Glass melting plant is described in DE 195 43 430 A1. At the Two-layer bricks are recesses for the partial reception of pipes Wall of a boiler room provided. To hang the It has two-layer stones that are oblique to the Main extension plane run. The depressions serve for vertical Hang the two-layer stone on hooks. Each of the wells extends spread over the entire width of the two-layer stone. Such deepening weaken the stability and are in perforated plates according to DE 296 14 856 U1 not suitable.

Aufgabe der Erfindung ist es, eine Lochplatte der eingangs genannten Art vorzuschlagen, die einfach, schraubenlos montierbar ist, ohne daß deren Stabilität und Lochstruktur wesentlich gestört wird.The object of the invention is to provide a perforated plate of the type mentioned propose that is simple, screwless, without their Stability and hole structure is significantly disturbed.

Erfindungsgemäß ist obige Aufgabe dadurch gelöst, daß an jedem in der Einbaulage vertikalen Seitenrand der Lochplatte wenigstens eine Aussparung vertieft ist, wobei die Lochplatte zur Halterung in einem Rahmen mit den Aussparungen auf Führungsstücke vertikaler Schenkel des Rahmens aufschiebbar ist, und daß die Grenzflächen zwischen den Aussparungen und den Führungsstücken in einem spitzen Winkel zur Horizontalen geneigt sind.According to the invention the above object is achieved in that in each of the Installation position vertical side edge of the perforated plate at least one recess is recessed, the perforated plate for mounting in a frame with the Cutouts on guide pieces of vertical legs of the frame is postponed, and that the interfaces between the recesses and the guide pieces are inclined at an acute angle to the horizontal.

Die Lochplatte ist einfach dadurch zu montieren, daß sie in den Rahmen eingesetzt wird, wobei die Führungsstücke des Rahmens in ihre Aussparungen greifen und die Aussparungen sich aufgrund des zur Horizontalen spitzen Winkels schräg nach unten verschieben bzw. gleiten, so daß sie unter Schwerkraftwirkung nicht von den Führungsstücken rutschen können. Da die Aussparungen nur an den vertikalen Seitenrändern der Lochplatte vorgesehen sind, können sie kaum zu einer Schwächung der Stabilität der Lochplatte, also auch nicht zu einer Bruchgefahr führen. Außerdem stören die Aussparungen die Lochstruktur der Lochplatte nicht, da sie nicht bis in den Bereich der Löcher reichen müssen.The perforated plate is easy to assemble by placing it in the frame is used, the guide pieces of the frame in their recesses grab and the recesses are tapered due to the horizontal Move or slide the angle diagonally downwards so that it is under The force of gravity cannot slide off the guide pieces. Since the Cutouts are only provided on the vertical side edges of the perforated plate are, they can hardly weaken the stability of the perforated plate, so also do not lead to a risk of breakage. The cutouts also interfere the perforated structure of the perforated plate is not, since it does not reach the area of the Holes have to suffice.

Vorzugsweise sind die Aussparungen feuerraumseitig geschlossen, erstrecken sich also nicht offen zur Feuerraumseite. Dadurch sind die Führungsstücke gegenüber der aggresiven Atmosphäre des Feuerraums abgedeckt. Sie können damit wie der Rahmen aus Metall bestehen und lassen sich somit einfach mit dem metallischen Rahmen verbinden, beispielsweise verschweißen.The cutouts are preferably closed on the combustion chamber side not open to the firebox side. This makes the guide pieces covered from the aggressive atmosphere of the firebox. she can be made of metal like the frame and can thus be just connect to the metallic frame, for example weld.

In Ausgestaltung der Erfindung weist die Lochplatte an ihrem oberen, horizontalen Seitenrand eine Abschrägung auf, deren Winkel etwa dem Winkel der Grenzflächen entspricht. Dies erleichtert bei der Montage das Einsetzen der Lochplatte in den Rahmen und bei der Demontage das Ausheben einer einzelnen Lochplatte aus dem Lochplattenverbund.In an embodiment of the invention, the perforated plate on its upper, horizontal bevel on a bevel whose angle is about the angle corresponds to the interfaces. This facilitates the installation of the Perforated plate in the frame and when disassembling lifting one single perforated plate from the perforated plate composite.

Die Aussparungen 14,15 sind voneinander getrennt. Sie gehen also nicht ineinander über. Die Aussparungen 14,15 erstrecken sich nicht über die gesamte Dicke D der Lochplatte 3, sondern nur über einen Teil D1 der Dicke. Sie sind damit zum Feuerraum 2 geschlossen und zum Raum 4 hin offen. On each of the two vertical side edges 12, 13 in the installed state rectangular, especially square perforated plate 3 is one Cutout 14.15 provided. The recesses 14, 15 are from one another Cut. So they don't merge. The recesses 14.15 do not extend over the entire thickness D of the perforated plate 3, but only over part D1 of the thickness. They are closed to the firebox 2 and open to room 4.

An den vertikalen Schenkel 8,9 des Rahmens 5 sind Flacheisen als Führungsstücke 16,17 angeschweißt, die den Aussparungen 14,15 zugeordnet sind. Einander zugewandte Grenzflächen 18,19 der Aussparungen 14,15 und der Führungsstücke 16,17 sind in einem spitzen Winkel W zur Horizontalen geneigt (vgl. Fig.1). Die Tiefe T der Aussparungen 14,15 entspricht etwa der Dicke d der Führungsstücke 16,17 (vgl. Fig.2,3,4) derart, daß die Aussparungen 14,15 gerade über die Führungsstücke 16,17 passen. Die Aussparungen 14,15 reichen dabei nicht bis in den Bereich der Lochplatte 3, in dem sich die rasterförmig verteilten Löcher 11 befinden.On the vertical legs 8.9 of the frame 5 are flat iron as Welded guide pieces 16, 17, which are assigned to the recesses 14, 15 are.
