Description

Die vorliegende Erfindung betrifft ein Rostbodenelement zum Aufbau eines Rostbodens der im Oberbegriff des Anspruches 1 beschriebenen Art, welcher beispielsweise zur Aufnahme von Feststoffen bei deren Verbrennung, Kühlung oder anderweitigen Warmbehandlung dient. Die zwischen den Lamellenkörpern verbleibenden Schlitze dienen zum Ausblasen eines Gases, beispielsweise Luft, welches das auf dem Rostboden aufliegende Material von unten nach oben durchströmt. Das Gas kann in bekannter Weise unterschiedliche Aufgaben erfüllen, nämlich z.B. eine Kühlung des Rostbodens, eine Kühlungs- oder Warmbehandlung des auf dem Rostboden aufliegenden Materials, eine Förderung dieses Materials usw..The present invention relates to a grate floor element for building up a grate floor of the type described in the preamble of claim 1, which is used, for example, to hold solids in their combustion, cooling or other heat treatment. The slots remaining between the lamellar bodies are used to blow out a gas, for example air, which flows through the material lying on the grate bottom from bottom to top. The gas can perform various tasks in a known manner, namely e.g. cooling the grate floor, cooling or heat treatment of the material lying on the grate floor, conveying this material, etc.

Derartige Rostböden sind im allgemeinen einem starken Verschleiß unterworfen. Das gilt insbesondere für den Einsatz beim Kühlen von Zementklinkern, die bei hohem Gewicht auch eine hohe Oberflächenrauhigkeit haben.Such grate floors are generally subject to heavy wear. This applies in particular to the use of cooling cement clinker, which also has a high surface roughness with a high weight.

Durch die EP 0 167 658 B1 ist bereits ein Rostbodenelement der im Oberbegriff des Anspruches 1 genannten Art bekannt. Dieses Rostbodenelement besteht aus zwei Grundbauteilen, von denen jedes einen Seitensteg sowie mehrere, im zweifachen Abstand des vorgesehenen Lamellenkörperabstandes mit diesem einstückig verbundene Lamellenkörper umfaßt; das Rostbodenelement wird montiert, indem zwei Seitenstege so miteinander verbunden werden, daß die Lamellenkörper des einen Seitensteges zwischen die Lamellenkörper des anderen Seitensteges greifen und in an diesem ausgebildete Aufnahmeöffnungen gesteckt werden. Um das aus den Grundbauteilen gebildete Rostbodenelement zusammenzuhalten, sind die Grundbauteile zusätzlich beispielsweise an der Unterseite des Rostbodenelementes miteinander verschraubt.A grate floor element of the type mentioned in the preamble of claim 1 is already known from EP 0 167 658 B1. This grate floor element consists of two basic components, each of which comprises a side web and a plurality of lamellar bodies which are integrally connected to the lamellar body spacing at twice the distance; the grate floor element is assembled by connecting two side webs so that the lamellar bodies of one side web grip between the lamellar bodies of the other side web and are inserted into receiving openings formed thereon. In order to hold the grate floor element formed from the basic components together, the Basic components additionally screwed together, for example on the underside of the grate floor element.

Ein Nachteil der bekannten Konstruktion liegt darin, daß bei einem ein zulässiges Maß überschreitenden Verschleiß einzelner Lamellenkörper und/oder Seitenstege jeweils das gesamte Rostbodenelement oder zumindest ganze Grundbauteile ausgewechselt werden müssen, wobei im letzteren Fall in aufwendiger Weise die die Bauteile zusammenhaltende Verbindung gelöst und nach dem Auswechseln eines Grundbauteiles wieder hergestellt werden muß. Dabei werden im allgemeinen immer auch noch brauchbare, unverschlissene Teile des Rostbodenelementes mitausgewechselt, was zu hohen Materialkosten führt; andererseits ist der Demontage- bzw. Montagevorgang langwierig, was regelmäßig zu längeren Stillstandszeiten für die ganze betroffene Anlage führt. Dieses Problem wird noch dadurch erschwert, daß jeweils mehrere Rostbodenelemente miteinander zu einem Rostboden verbunden und dieser Rostboden wiederum auf einem Rostträger befestigt ist, so daß beispielsweise die Notwendigkeit, einzelne Lamellenkörper auszuwechseln, immer dazu führt, daß auch die damit verbundenen Stege ausgewechselt werden müssen und daß auch deren Verbindung zu den Stegen benachbarter Rostbodenelemente sowie zum Rostträger gelöst und nach dem Auswechseln wieder hergestellt werden muß.A disadvantage of the known construction is that in the event of wear of individual lamellar bodies and / or side webs exceeding a permissible level, the entire grate floor element or at least entire base components must be replaced, in the latter case the connection holding the components together being released in a complex manner and after Replacing a basic component must be restored. In general, usable, non-worn parts of the grate floor element are also also replaced, which leads to high material costs; on the other hand, the disassembly or assembly process is lengthy, which regularly leads to longer downtimes for the entire system concerned. This problem is exacerbated by the fact that several grate floor elements are connected to each other to form a grate floor and this grate floor is in turn fastened on a grate support, so that, for example, the need to replace individual lamella bodies always means that the associated webs must also be replaced and that their connection to the webs of adjacent grate floor elements and to the grate support must be released and restored after replacement.

Es ist die Aufgabe der vorliegenden Erfindung, ein Rostbodenelement der im Oberbegriff des Anspruches 1 genannten Art zu schaffen, bei welchem ein Auswechseln einzelner, verschlissener Teile mit geringerem Montageaufwand und materialsparend möglich ist.It is the object of the present invention to provide a grate floor element of the type mentioned in the preamble of claim 1, in which an exchange of individual, worn parts is possible with less installation effort and in a material-saving manner.

Diese Aufgabe ist erfindungsgemäß durch die im Anspruch 1 beschriebenen Merkmale gelöst.This object is achieved by the features described in claim 1.

Die Grundidee der vorliegenden Erfindung besteht darin, das Rostbodenelement anders als bisher in einen die beiden Seitenstege miteinander verbindenden Rahmen sowie einzelne, mit diesem Rahmen verbindbare Lamellenkörper aufzuteilen. Damit wird zunächst dem Umstand Rechnung getragen, daß vor allem die Lamellenkörper einem erhöhten Verschleiß unterworfen sind und ausgewechselt werden müssen. Die erfindungsgemäße Konstruktion erlaubt es, einzelne Lamellenkörper mit geringem Montageaufwand zu ersetzen, ohne gleichzeitig noch intakte Seitenstege auszuwechseln. Die Verbindung der Lamellenkörper mit den Seitenstegen läßt sich konstruktiv äußerst einfach lösen, wie anhand mehrerer Ausführungsbeispiele genauer beschrieben wird.The basic idea of the present invention is to divide the grate floor element into a frame that connects the two side webs to one another, as well as individual slat bodies that can be connected to this frame. This takes account of the fact that, above all, the lamellar bodies are subject to increased wear and must be replaced. The construction according to the invention allows individual slat bodies to be replaced with little assembly effort, without at the same time replacing intact side webs. The connection of the lamellar bodies to the side webs can be solved extremely simply in terms of construction, as will be described in more detail using several exemplary embodiments.

Ein weiterer Vorteil ergibt sich dadurch, daß die beiden Seitenstege eines Rostbodenelementes nicht mehr in der beschriebenen Weise miteinander verschraubt und in anderer Weise miteinander verbunden werden müssen.Another advantage results from the fact that the two side webs of a grate floor element no longer have to be screwed to one another in the manner described and have to be connected to one another in another way.

Die gemäß der vorliegenden Erfindung vorgenommene Aufteilung des Rostbodenelementes folgt damit den unterschiedlichen Funktionen der Seitenstege einerseits, die vorzugsweise als Montageelemente für die Lamellenkörper dienen, und dieser Lamellenkörpern andererseits, die vorzugsweise die Rostoberfläche bilden und damit bevorzugtem Verschleiß unterliegen. Diese Aufteilung ermöglicht es beispielsweise auch, den Rahmen einerseits und die Lamellenkörper andererseits aus unterschiedlichen, an ihre jeweiligen Funktionen optimal angepaßten Materialien herzustellen.The division of the grate floor element according to the present invention thus follows the different functions of the side webs on the one hand, which preferably serve as mounting elements for the slat bodies, and these slat bodies on the other hand, which preferably form the grate surface and are therefore subject to preferential wear. This division also makes it possible, for example, to manufacture the frame on the one hand and the lamella body on the other hand from different materials that are optimally adapted to their respective functions.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, daß die Seitenstege jeweils ein in Längsrichtung desselben verlaufendes, als Führungsschiene dienendes Längsführungsprofil aufweisen, und daß die Lamellenkörper an ihren seitlichen Enden jeweils ein mit einem zugeordneten Längsführungsprofil zusammenwirkendes Gegenprofil haben. Diese Ausbildung ermöglicht eine besonders einfache Montage der Lamellenkörper, indem diese einfach hintereinander in die Längsführungsprofile der Seitenstege einfgefädelt werden.In a preferred embodiment of the invention it is provided that the side webs each run in the longitudinal direction as a guide rail have serving longitudinal guide profile, and that the lamellar bodies each have at their lateral ends a cooperating with an associated longitudinal guide profile counter profile. This design enables a particularly simple assembly of the lamellar bodies by simply threading them one behind the other into the longitudinal guide profiles of the side webs.

Die Längsführungsprofile können als Nuten und die Gegenprofile dementsprechend als Federwülste ausgebildet sein oder umgekehrt, wie anhand unterschiedlicher Ausführungsbeispiele dargestellt wird.The longitudinal guide profiles can be designed as grooves and the counter profiles accordingly as spring beads or vice versa, as is shown with the aid of different exemplary embodiments.

Bei einer bevorzugten Ausgestaltung der Erfindung sind die Seitenstege durch zueinander parallele, senkrecht auf der Rahmenebene stehende Seitenwände gebildet, wobei die Seitenwände zumindest an einer ersten Rahmenstirnseite durch eine Stirnwand mit einer gegenüber den Seitenwänden geringeren Wandhöhe miteinander verbunden sind; die Längsführungsprofile sind dann an den einander zugewandten Innenflächen der Seitenwände oberhalb dieser Stirnwand ausgebildet, so daß sie an der ersten Rahmenstirnseite in die Endkanten der Seitenwände auslaufen können. Diese Konstruktion ermöglicht es, die Lamellenkörper von der ersten Rahmenstirnseite her geradlinig zwischen den Seitenstegen aufzureihen, so daß das gesamte Rostbodenelement ein kompaktes, nach außen glattes Bauteil darstellt, welches in einfacher Weise gasdicht mit anderen Rostbodenelementen zu einem Rostboden verbunden werden kann.In a preferred embodiment of the invention, the side webs are formed by side walls parallel to one another and perpendicular to the frame plane, the side walls being connected to one another at least on a first frame front side by an end wall with a lower wall height than the side walls; the longitudinal guide profiles are then formed on the mutually facing inner surfaces of the side walls above this end wall, so that they can run into the end edges of the side walls on the first frame end face. This construction makes it possible to line up the lamella body in a straight line from the first frame end face between the side webs, so that the entire grate floor element is a compact component that is smooth on the outside and can be connected in a gas-tight manner to other grate floor elements to form a grate floor.

Dabei ist die erste Rahmenstirnseite vorzugsweise die in Förderrichtung vordere Stirnseite, die dem einem Verschleiß am stärksten unterworfenen Bereich des Rostbodenelementes entspricht, so daß die jeweils auszuwechselnden Lamellenkörper auch als erste zugänglich sind.The first frame end face is preferably the front end face in the conveying direction, which the one Wear corresponds to the area of the grate floor element that is most subjected to wear, so that the lamella bodies to be replaced are also the first to be accessible.

Um die Lage der Lamellenkörper in Längsrichtung der Seitenstege bzw. gegenüber benachbarten Lamellenkörpern festzulegen, ist erfindungsgemäß weiter vorgesehen, daß die Lamellenkörper Abstandsvorsprünge aufweisen, die zur Anlage an einem benachbarten Lamellenkörper bestimmt sind; diese erlauben es, die Lamellenkörper jeweils bis zum Anschlag hintereinander in die Längsführungsprofile einzufädeln, wobei diese Abstandsvorsprünge auch den zwischen den Lamellenkörpern verbleibenden Gasaustrittsschlitz definieren.In order to determine the position of the lamellar bodies in the longitudinal direction of the side webs or in relation to adjacent lamellar bodies, it is further provided according to the invention that the lamellar bodies have spacing projections which are intended for contact with an adjacent lamellar body; these allow the lamellar bodies to be threaded one after the other into the longitudinal guide profiles up to the stop, these spacing projections also defining the gas outlet slot remaining between the lamellar bodies.

Eine weitere wesentliche Verbesserung im Sinne der vorne beschriebenen Aufgabenteilung des Rahmens einerseits und der Lamellenkörper andererseits wird dadurch erreicht, daß die Lamellenkörper an ihren seitlichen Enden jeweils einen zur Abdeckung der Oberkante eines zugeordneten Seitensteges ausgelegten Längsflansch haben. Beim Einfädeln der Lamellenkörper in die Längsführungsprofile legen sich die Längsflansche auf die Oberkante der zugeordneten Seitenstege und decken diese nach oben ab. Dadurch werden die Seitenstege gegen einen Verschleiß durch das auf dem Rostboden liegende Material wirksam geschützt, so daß ein Auswechseln der Rahmen überhaupt nicht mehr erforderlich wird.A further significant improvement in the sense of the division of tasks of the frame, on the one hand, and the slat body, on the other hand, is achieved in that the slat bodies each have at their lateral ends a longitudinal flange designed to cover the upper edge of an associated side web. When threading the lamellar bodies into the longitudinal guide profiles, the longitudinal flanges lie on the upper edge of the associated side webs and cover them upwards. As a result, the side webs are effectively protected against wear from the material lying on the grate floor, so that it is no longer necessary to replace the frame at all.

Bei einer Ausbildung der Lamellenkörper in der Weise, daß sie jeweils einen die Rostbodenoberfläche bildenden Hauptabschnitt und einen einen benachbarten Lamellenkörper untergreifenden Ansatz haben, ist vorgesehen, daß die zum Eingriff in die Längsführungsprofile bestimmten Gegenprofile sowie die zum Abdecken der Seitenstege bestimmten Längsflansche jeweils nur an den seitlichen Enden des Hauptabschnittes ausgebildet sind.In the case of a configuration of the lamella bodies in such a way that they each have a main section forming the grate floor surface and an extension that engages under an adjacent lamella body, that the mating profiles intended for engagement in the longitudinal guide profiles and the longitudinal flanges intended for covering the side webs are each formed only at the lateral ends of the main section.

Um die Lamellenkörper gegenüber dem Rahmen zu befestigen, ist als besonders einfache Lösung ein Abschluß-Lamellenkörper vorgesehen, welcher mit Mitteln zum Arretieren desselben am Rahmen ausgestattet ist. Dieser Abschluß-Lamellenkörper wird als letzter Lamellenkörper in das Längsführungsprofil eingeführt und auf irgendeine geeignete Weise mit dem Rahmen verbunden, so daß es die anderen Lamellenkörper festhält. Die Befestigung des Abschluß-Lamellenkörpers kann beispielsweise durch Schweißen, durch Verschrauben, durch Verrasten oder in anderer, bekannter Weise erfolgen.In order to fasten the slat body relative to the frame, a particularly simple solution provides a closing slat body which is equipped with means for locking the same to the frame. This final lamellar body is inserted as the last lamellar body in the longitudinal guide profile and connected to the frame in any suitable manner so that it holds the other lamellar bodies. The final lamellar body can be attached, for example, by welding, screwing, locking or in another known manner.

Ein bevorzugter Anwendungsbereich der erfindungsgemäßen Rostbodenelemente sind sogenannte Stufenroste. In diesem Falle hat der Rahmen in seinem der ersten Rahmenstirnseite zugeordneten Endbereich eine Bodenwand und in seinem der ersten Rahmenstirnseite fernen Endbereich eine Deckenwand, wobei sich jedes Rostbodenelement mit der Bodenwand auf die Deckenwand eines in Förderrichtung des Auflagegutes folgenden Rostbodenelementes legt. Die vordere Rahmenstirnseite aller Rostbodenelemente bleibt auf diese Weise auch im montierten Zustand stets zugänglich, so daß ein Auswechseln einzelner Lamellenkörper möglich wird, ohne den zugeordneten Rahmen zu demontieren.A preferred application of the grate floor elements according to the invention are so-called step grates. In this case, the frame has a bottom wall in its end region assigned to the first frame end face and a ceiling wall in its end region remote from the first frame end face, each grate floor element laying with the bottom wall on the top wall of a grate floor element following in the conveying direction of the material to be supported. In this way, the front face of all grate floor elements always remains accessible even in the assembled state, so that individual slat bodies can be replaced without having to dismantle the associated frame.

Zur folgenden Beispielsbeschreibung wird auch auf die EP 0 167 658 B1 verwiesen, die in der Beschreibungseinleitung genannt ist. Diese zeigt in Figur 8 Einzelheiten zum grundsätzlichen Aufbau eines Rostbodens mit Hilfe von Rostbodenelementen. Mehrere bezüglich der Förderrichtung des Auflagegutes nebeneinander angeordnete und miteinander verbundene Rostbodenelemente ergeben eine Rostreihe; mehrere in Förderrichtung hintereinander angeordnete Rostreihen ergeben den Rostboden. Dabei können die in Förderrichtung hintereinander liegenden Rostbodenelemente stufenartig angeordnet sein, wie in der vorliegenden Figur 1 angedeutet ist.For the following example description, reference is also made to EP 0 167 658 B1, which is mentioned in the introduction to the description. This shows in Figure 8 details of the basic structure of a grate floor with the help of grate floor elements. Several regarding the Direction of conveyance of the material to be placed next to one another and connected to each other grate bottom elements result in a grate row; several grate rows arranged one behind the other in the conveying direction form the grate floor. The grate floor elements lying one behind the other in the conveying direction can be arranged in steps, as indicated in the present FIG. 1.

Das aus einem vorzugsweise einstückigen Rahmen 2 und einer Vielzahl von in der durch den Pfeil 4 bezeichneten Förderrichtung hintereinander angeordneten Lamellenkörpern 6 gebildete Rostbodenelement 8 ist auf einen Rostträger 10 aufgesetzt. Der Rostträger 10 ist in nicht dargestellter Weise an eine Gaszuführungsleitung angeschlossen. Wie insbesondere aus Figur 3 ersichtlich ist, umfaßt der Rahmen 2 zwei Seitenstege 12, 14, die als auf der Rahmenhauptebene senkrecht stehende Seitenwände ausgebildet sind. Die Seitenwände 12, 14 sind an ihrer in Förderrichtung vorderen Rahmenstirnseite 15 durch eine Stirnwand 16 miteinander verbunden, die eine gegenüber den Seitenwänden 12, 14 niedrigere Wandhöhe hat, so daß die Seitenwände 12, 14 über die Oberkante der Stirnwand 16 überstehen.The grate bottom element 8, which is formed from a preferably one-piece frame 2 and a multiplicity of lamella bodies 6 arranged one behind the other in the conveying direction indicated by the arrow 4, is placed on a grate carrier 10. The grate carrier 10 is connected in a manner not shown to a gas supply line. As can be seen in particular from Figure 3, the frame 2 comprises two side webs 12, 14, which are formed as perpendicular to the main frame level side walls. The side walls 12, 14 are connected to one another at their front frame end face 15 in the conveying direction by an end wall 16 which has a lower wall height than the side walls 12, 14, so that the side walls 12, 14 project beyond the upper edge of the end wall 16.

Wie aus den Figuren 2 und 3 ersichtlich ist, sind an den einander zugewandten Innenflächen der Seitenwände 12, 14 Längsnuten 18, 20 ausgebildet, die als Längsführungsprofile zur Aufnahme von Lamellenkörpern 6 dienen. Diese Längsnuten sind oberhalb der Stirnwand 16 angeordnet und laufen im Bereich der vorderen Rahmenstirnseite in die Endkanten der Seitenwände aus, so daß sie von dieser Seite her zugänglich sind.As can be seen from FIGS. 2 and 3, longitudinal grooves 18, 20 are formed on the mutually facing inner surfaces of the side walls 12, 14, which serve as longitudinal guide profiles for receiving lamellar bodies 6. These longitudinal grooves are arranged above the end wall 16 and run in the region of the front end of the frame into the end edges of the side walls, so that they are accessible from this side.

Figur 4 zeigt einen Lamellenkörper 6. Dieser besteht im wesentlichen aus einem die Rostbodenoberfläche bildenden Hauptabschnitt 22 und einem daran angeordneten Ansatz 24, welcher in der in Figur 1 dargestellten Weise jeweils einen benachbarten Lamellenkörper untergreift. An den seitlichen Enden des Hauptabschnittes 22 sind Federwülste 26 bzw. 28 ausgebildet, die zu den Längsnuten 18, 20 komplementär geformt sind. Die Lamellenkörper 6 werden von der vorderen Rahmenstirnseite 15 her in die Längsnuten 18, 20 hintereinander eingefädelt.FIG. 4 shows a lamellar body 6. This essentially consists of a main section 22 forming the grate floor surface and an attachment 24 arranged thereon, which in the manner shown in FIG. 1 engages under an adjacent lamellar body. At the lateral ends of the main section 22 spring beads 26 and 28 are formed, which are complementary to the longitudinal grooves 18, 20. The lamellar bodies 6 are threaded one behind the other from the front frame end 15 into the longitudinal grooves 18, 20.

An den in Einschieberichtung vorderen Kanten des Hauptabschnittes 22 sind zwei Abstandsvorsprünge 30, 32 ausgebildet, die sich an die Hinterkanten des jeweils vorher eingefädelten Lamellenkörpers 6 anlegen. Diese Abstandsvorsprünge definieren den zwischen den Lamellenkörpern 6 verbleibenden Gasausblaseschlitz 34 (siehe Figur 1). Die Abstandsvorsprünge sind in einfacher Weise durch Schleifen zu verkleinern bzw. durch Auftragsschweißen zu vergrößern, so daß die Schlitzbreite variiert werden kann.On the front edges of the main section 22 in the direction of insertion, two spacing projections 30, 32 are formed, which abut the rear edges of the previously threaded lamella body 6. These spacing projections define the gas blowout slot 34 remaining between the lamellar bodies 6 (see FIG. 1). The spacing projections can be easily reduced by grinding or increased by cladding so that the slot width can be varied.

Um die Lamellenkörper 6 im Rahmen zu sichern, wird als letztes ein Abschluß-Lamellenkörper 36 eingefädelt, welcher sich von einem normalen Lamellenkörper 6 dadurch unterscheidet, daß der Hauptabschnitt 38 an seinem in Einschieberichtung hinteren Ende einen nach unten stehenden Abschlußflansch 40 hat, welcher im wesentlichen bis zur Oberkante der Stirnwand 16 reicht. Am Abschlußflansch 40 einerseits und an der Stirnwand 16 andererseits sind Mittel zum Arretieren des Abschluß-Lamellenkörpers 36 am Rahmen 2 ausgebildet. Im dargestellten Ausführungsbeispiel hat vorzugsweise zumindest eine der beiden aneinanderliegenden Kanten des Abschlußflansches 40 bzw. der Stirnwand 16 ein Fase, die in einfacher Weise die Herstellung einer Verbindungsschweißnaht 42 ermöglicht.In order to secure the lamellar body 6 in the frame, a final lamellar body 36 is threaded last, which differs from a normal lamellar body 6 in that the main section 38 has, at its rear end in the direction of insertion, a lower end flange 40 which essentially extends to the upper edge of the end wall 16. On the end flange 40 on the one hand and on the end wall 16 on the other hand, means for locking the end plate body 36 to the frame 2 are formed. In the illustrated embodiment, at least one of the two adjacent edges of the End flange 40 and the end wall 16 a bevel, which enables the production of a connection weld 42 in a simple manner.

Figur 6 zeigt eine Einzelheit eines anderen Ausführungsbeispieles für die Längsführung der Lamellenkörper im Rahmen. Die Figur 6 zeigt zwei aneinanderliegende Seitenwände 44 bzw. 46 zweier in einer Rostreihe nebeneinander angeordneter Rostbodenelemente. Die Seitenwände 44, 46 haben an ihrem jeweils oberen Ende einen als Längsführungsprofil dienenden Federwulst 48, 50, während die an den Lamellenkörpern 52 bzw. 54 angeordneten Gegenprofile als zu den Federwülsten komplementäre Nuten 56 bzw. 58 ausgebildet sind.Figure 6 shows a detail of another embodiment for the longitudinal guidance of the slat body in the frame. FIG. 6 shows two adjacent side walls 44 and 46 of two grate floor elements arranged side by side in a grate row. The side walls 44, 46 have at their respective upper ends a spring bead 48, 50 serving as a longitudinal guide profile, while the counter profiles arranged on the lamellar bodies 52 and 54 are designed as grooves 56 and 58 complementary to the spring beads.

Wie Figur 6 weiter erkennen läßt, haben die Lamellenkörper 52 bzw. 54 an ihren seitlichen Enden jeweils einen zur Abdeckung der Oberkante einer zugeordneten Seitenwand 44 bzw. 46 ausgelegten Längsflansch 56 bzw. 58. Diese verhindern, daß die Seitenwände 44, 46 mit auf dem Rost liegendem Auflagegut in Berührung kommen, so daß ein Verschleiß auf die Lamellenkörper beschränkt bleibt, die in einfacher Weise ausgewechselt werden können.As can also be seen in FIG. 6, the lamellar bodies 52 and 54 each have at their lateral ends a longitudinal flange 56 and 58 designed to cover the upper edge of an associated side wall 44 and 46. These prevent the side walls 44, 46 from being on the Rust lying material come into contact, so that wear is limited to the lamellar body, which can be replaced in a simple manner.

Wie die Figuren 1 und 3 erkennen lassen, hat der Rahmen 2 in seinem der ersten Rahmenstirnseite 15 zugeordneten Endbereich eine Bodenwand 60, die den über den Rostträger 10 überstehenden Bereich von unten her abdeckt. Der auf den Rostträger 10 aufgesetzte Bereich des Rahmens ist unten offen, so daß Gas aus dem Rostträger in das Rostbodenelement 8 eintreten und zu den Gasausblaseschlitzen 34 strömen kann. Die Bodenwand 60 schließt den Rahmen 2 in dem über den Rostträger 10 überstehenden Bereich nach unten gasdicht ab.As can be seen in FIGS. 1 and 3, the frame 2 has a bottom wall 60 in its end area assigned to the first frame end face 15, which covers the area protruding beyond the grate carrier 10 from below. The area of the frame placed on the grate carrier 10 is open at the bottom, so that gas from the grate carrier can enter the grate base element 8 and flow to the gas outlet slots 34. The bottom wall 60 closes the frame 2 in a gas-tight manner in the area projecting beyond the grate carrier 10.

In seinem der ersten Rahmenstirnseite 15 fernen Endbereich ist der Rahmen 2 durch eine Deckenwand 62 abgedeckt. An die der vorderen Rahmenstirnseite zugewandte Endkante der Deckenwand legt sich der erste Lamellenkörper an. In seinem der ersten Rahmenstirnseite zugewandten Bereich ist die Deckenwand vorzugsweise ähnlich dem Hauptabschnitt 22 eines Lamellenkörpers profiliert, so daß zwischen der Deckenwand und dem Ansatz 24 des ersten Lamellenkörpers ebenfalls ein Gasausblaseschlitz gebildet wird.In its end region remote from the first frame end face 15, the frame 2 is covered by a ceiling wall 62. The first slat body is placed on the end edge of the ceiling wall facing the front end of the frame. In its area facing the first end face of the frame, the top wall is preferably profiled in a manner similar to the main section 22 of a lamellar body, so that a gas blowout slot is likewise formed between the top wall and the shoulder 24 of the first lamellar body.

Die Figuren 1 und 2 zeigen jeweils einen mit 64 bezeichneten schraffierten Bereich, der das übliche Verschleißbild eines Rostbodenelementes kennzeichnet. Daraus ergibt sich, daß vorzugsweise die in Transportrichtung des Auflagegutes vorderen Bereiche verschleißen. Wenn der Verschleiß eine zulässige Grenze erreicht hat, wird im Falle des anhand der Figuren 1 bis 5 beschriebenen Ausführungsbeispieles die den Abschluß-Lamellenkörper 36 fixierende Schweißnaht 42 durchgetrennt, so daß die vorderen Lamellenkörper entfernt und durch neue ersetzt werden können. Der Verschleiß an den Oberkanten der Seitenwände 12, 14 wird beispielsweise durch Auftragsschweißen ausgeglichen. Dabei kommt es einer einfachen Auswechselbarkeit der Lamellenkörper entgegen, daß die dem größten Verschleiß unterliegenden Lamellenkörper im Bereich der vorderen Stirnseite 15 angeordnet sind, so daß sie ausgewechselt werden können, ohne die nicht verschlissenen Lamellenkörper zu demontieren.Figures 1 and 2 each show a hatched area designated 64, which characterizes the usual wear pattern of a grate floor element. The result of this is that the front regions in the transport direction of the material to be supported preferably wear out. When the wear has reached a permissible limit, in the case of the exemplary embodiment described with reference to FIGS. 1 to 5, the weld 42 which fixes the end lamellar body 36 is severed, so that the front lamellar body can be removed and replaced by new ones. The wear on the upper edges of the side walls 12, 14 is compensated for, for example, by cladding. In this case, it is easy to replace the lamellar bodies in that the lamellar bodies which are subject to the greatest wear are arranged in the region of the front end face 15, so that they can be replaced without dismantling the lamellar bodies which are not worn.

Bei dem anhand der Figur 6 beschriebenen Ausführungsbeispiel genügt ein Auswechseln der Lamellenkörper 52, 54, da die Seitenwände 44, 46 keinem Verschleiß unterliegen können.In the exemplary embodiment described with reference to FIG. 6, it is sufficient to replace the slat bodies 52, 54, since the side walls 44, 46 cannot be subject to wear.

Figur 1 zeigt schematisch die Anordnung eines weiteren, in Transportrichtung 4 vor dem Rostbodenelement 2 angeordneten Rostbodenelementes 70 einer weiteren Rostreihe, die stufenartig nach unten versetzt angeordnet ist. Dabei überlappt das obere Rostbodenelement 8 das untere Rostbodenelement 70 höchstens im Bereich der Deckenwand 62, damit die wirksame Rostbodenfläche nicht verkleinert wird. Wie weiter ersichtlich ist, bleibt die vordere Stirnseite aller Rostbodenelemente wegen der gestuften Anordnung stets zugänglich, so daß ein Auswechseln der vorzugsweise verschleißenden Lamellenkörper 6 ohne Demontage der Rostbodenelemente möglich ist. Auch andere verschleißbedingte Reparaturarbeiten, wie beispielsweise das Auftragsschweißen der Seitenwände 12, 14 ist ohne Demontage der Rostbodenelemente von oben her möglich.FIG. 1 schematically shows the arrangement of a further grate floor element 70, arranged in the transport direction 4 in front of the grate floor element 2, of a further grate row, which is arranged in a step-like manner downwards. The upper grate floor element 8 overlaps the lower grate floor element 70 at most in the area of the ceiling wall 62, so that the effective grate floor area is not reduced. As can also be seen, the front end face of all grate floor elements remains accessible due to the stepped arrangement, so that the preferably wear-resistant lamellar bodies 6 can be replaced without dismantling the grate floor elements. Other wear-related repair work, such as the build-up welding of the side walls 12, 14 is also possible from above without dismantling the grate floor elements.
