Description

Vorrichtung und Verfahren zur Bildung eines Rostbodens bestehend aus untereinander formschlüssig verbundenen Lamellen körpern.Apparatus and method for forming a grate floor consisting of slats which are positively connected to one another.
Die vorliegende Erfindung betrifft die Bildung eines durchfallfreien Rostbodens aus untereinander formschlüssig verbundenen Lamellenkörpern zur Aufnahme von Schüttgut bei deren Verbrennung, Kühlung oder anderweitiger Behandlung, insbesondere zum Kühlen von gebrannten Schüttgütern, mittels eines zwischen den Lamellenkörpern strömenden Gases.The present invention relates to the formation of a diarrhea-free grate from interlocking lamellar bodies for receiving bulk goods during their combustion, cooling or other treatment, in particular for cooling fired bulk goods, by means of a gas flowing between the lamellar bodies.
Der in den Patentansprüchen 1 und 2 angegebenen Erfindung liegen folgende Probleme zugrunde: Rostböden sind starkem Verschleiß unterworfen, insbesondere beim Einsatz in Kühlern zur thermischen Behandlung von Zementklinker. Die Masse der zu wechselnden Verschleißteile ist erheblich und geht über die mit dem Fördergut in Kontakt stehenden Anlageflächen zum Teil deutlich hinaus. Auch verschleißende Verbindungselemente sind kostenintensiv und nachteilig, insbesondere wenn sie zur Wartung nur noch durch Brennschneiden lösbar sind und nicht mehr, wie bei der Montage üblich, durch Verschrauben. Außerdem ist die Zugänglichkeit bei Montagearbeiten überkopf von unterhalb des Rostbodens schwierig. Komplizierte Verbindungselemente und Montageabläufe erfordern geschultes Personal und sind kostenintensiv.The invention specified in claims 1 and 2 is based on the following problems: Rust floors are subject to heavy wear, in particular when used in coolers for the thermal treatment of cement clinker. The mass of the wear parts to be changed is considerable and in some cases goes well beyond the contact surfaces in contact with the material to be conveyed. Wearable connecting elements are also cost-intensive and disadvantageous, especially if they can only be removed for maintenance by flame cutting and no longer, as is customary during assembly, by screwing. In addition, it is difficult to access overhead assembly work from below the grate floor. Complicated connecting elements and assembly processes require trained personnel and are cost-intensive.
In Schubrostkühlern wird der Rostboden aus Rostplatten, die auf Rostträgern befestigt sind, derart gebildet, dass die Rostplatten in Längsrichtung schuppenartig übereinandergreifen und abwechselnd ortsfest bzw. in Längsrichtung des Rostes hin und her beweglich sind, wie im Patent DE-PS 952 785 beschrieben. Die Rostplatten weisen Durchbrüche an der Oberfläche auf, durch die das Kühlmedium, bevorzugt Luft, dem daraufliegenden Schüttgut zugeführt wird. Diese Rostplatten werden üblicherweise auf Rostträger montiert.In sliding grate coolers, the grate floor is formed from grate plates which are fastened to grate supports in such a way that the grate plates overlap in the longitudinal direction in a scale-like manner and are alternately stationary or movable back and forth in the longitudinal direction of the grate, as described in patent DE-PS 952 785. The grate plates have openings on the surface through which the cooling medium, preferably air, is fed to the bulk material lying thereon. These grate plates are usually mounted on grate supports.
Der Nachteil der bekannten Konstruktion liegt darin, dass die Rostplatten aus einem Stück gegossen oder geschweißt sind. Bei unterschiedlichem Wärmeeintrag, z.B. Kühlluft von unten und sehr heißes Material von oben, verwerfen sich die Rostplatten und/oder sie reißen. Eine Verkleinerung der Rostplatten und Rostträger ist nicht wirtschaftlich und potenziert die Anzahl der Schub- und Seitenspalte und somit den unerwünschten Rostdurchfall durch diese Spalte. Außerdem kann Schüttgut durch die Durchbrüche in der Oberfläche fallen und verursacht Verschleiß. Zusätzlich wird ein Transportsystem zur Entsorgung des Rostdurchfalls erforderlich.The disadvantage of the known construction is that the grate plates are cast or welded from one piece. With different heat input, e.g. Cooling air from below and very hot material from above, the grate plates warp and / or tear. A reduction in the size of the grate plates and grate supports is not economical and increases the number of slide and side gaps and thus the undesired grate diarrhea caused by these gaps. Bulk material can also fall through the openings in the surface and cause wear. In addition, a transport system is required to dispose of the grate diarrhea.
Bei moderneren Rostkühlem ist die Rostplatte durch ein Rostbodenelement in Form eines Kastens, wie in dem Patent DE 33 32 592 C1 , ersetzt worden. Dieser Kasten ist auf einem als Luftbalken bezeichnetem Rostträger befestigt. Zum Teil wird dem Luftbalken über mehrere Leitungsanschlüsse das Kühlmedium direkt zugeführt und von dort weiter auf die kastenförmigen Rostbodenelemente verteilt. Das kastenförmige Rostbodenelement, weiterhin als Rostplatte bezeichnet, eröffnet die Möglichkeit, dass die Rostoberfläche durch überlappende Profile gebildet wird, die den Rostdurchfall reduzieren.In more modern grate coolers, the grate plate has been replaced by a grate bottom element in the form of a box, as in the patent DE 33 32 592 C1. This box is attached to a grate support called an air bar. In some cases, the cooling medium is fed directly to the air bar via several line connections and from there it is further distributed to the box-shaped grate floor elements. The box-shaped grate floor element, also referred to as the grate plate, opens up the Possibility that the grate surface is formed by overlapping profiles that reduce the grate diarrhea.
Der wesentliche Nachteil der bekannten Konstruktion liegt darin, dass die verschleißende Rostoberfläche ein fest verbundener Bestandteil der kastenförmigenThe main disadvantage of the known construction is that the wearing grate surface is a firmly connected part of the box-shaped

Ein weiterer Nachteil dieser bekannten Konstruktion liegt darin, dass solcheAnother disadvantage of this known construction is that such

Es ist die Aufgabe der vorliegenden Erfindung, einen Rostboden nach der in Oberanspruch 1 und 2 genannten Art mit einfachen konstruktiven Mitteln zu verbessern und vielseitiger einsetzbar zu machen. Diese Aufgabe ist erfindungsgemäß durch die in Anspruch 1 und 2 beschriebenen Merkmale wie folgt gelöst.It is the object of the present invention to improve a grate floor according to the type mentioned in the claims 1 and 2 with simple constructional means and to make it more versatile. This object is achieved as follows by the features described in claims 1 and 2.
Durch zusammenstecken von Lamellenkörpern wird ein Rostboden gebildet, der aus kleinen thermisch unempfindlichen Lamellenkörpern mit genügend Wärmeausdehnungsfugen besteht, und bei welchem die Lamellenkörper einen bis auf vorzugsweise einen Freiheitsgrad beschränkten Formschluss aufweisen.By plugging together lamellar bodies, a grate floor is formed, which consists of small, thermally insensitive lamellar bodies with sufficient thermal expansion joints, and in which the lamellar bodies have a form fit that is preferably limited to one degree of freedom.
Der solchermaßen gebildete Rostboden lässt sich äußerst vorteilhaft und vielseitig hinsichtlich der Gasdurchtritte gestalten, insbesondere wenn die Gasdurchtrittsöffnung zwischen den Lamellenkörpern durch das Zusammenfügen der Lamellenkörper gebildeten wird. Besonders vorteilhaft ist die Ausbildung der Gasaustrittsöffnung als ein in Transportrichtung geneigter Schlitz über die gesamte Breite der Lamellenkörper. Durch Überlappung der Lamellenkörper kann der Gasschlitz mit einer Mulde unterhalb der Rostoberfläche so ausgebildet werden, dass kein Schüttgut unter den Rostboden fallen kann.The grate floor formed in this way can be designed to be extremely advantageous and versatile with regard to the gas passages, in particular if the gas passage opening between the lamella bodies is formed by joining the lamella bodies together. It is particularly advantageous to design the gas outlet opening as a slot that is inclined in the transport direction over the entire width of the lamellar bodies. By overlapping the lamellar bodies, the gas slot can be formed with a trough below the grate surface in such a way that no bulk material can fall under the grate floor.
Eine beidseitige Umströmung der L;-<meιιenkörper sichert eine gute Kühlung der Lamellenköφer und reduziert Wärmespannungen. Der Formschluss der zusammengesteckten Lamellenköφer und die freie Gestaltung der Befestigung auf eine Tragstruktur ermöglicht die Ausbildung von Wärmeausdehnungsfugen, um Verwerfungen und Risse zu vermeiden.A flow around the L; - <meιιenkörte ensures good cooling of the lamellar body and reduces thermal stresses. The positive locking of the assembled lamellar body and the free design of the attachment to a support structure enables the formation of thermal expansion joints to avoid warping and cracks.
Eine besonders vorteilhafte Ausgestaltung der vorliegenden Erfindung wird dadurch geschaffen, dass eine Trennung von Rostboden und Tragstruktur den vielseitigen Einsatz dieses Rostbodens auf unterschiedlichsten Rosten ermöglicht wie zum Beispiel für bekannte stationäre Schrägroste im Kühlereinlaufbereich, angetriebene Schubroste und Roste mit einem ebenen Rostboden sowie für diverse andere Roste, auf denen Schüttgut transportiert und wärmebehandelt wird.A particularly advantageous embodiment of the present invention is created in that a separation of the grate floor and support structure enables the versatile use of this grate floor on a wide variety of grates, for example for known stationary slanted grates in the radiator inlet area, driven sliding grates and grates with a flat grate floor and for various other grates on which bulk goods are transported and heat treated.
Insbesondere bei allen geschlossenen Rostplatten, die eine kastenförmige Struktur aufweisen, d.h. eine mit Ausblasöffnungen versehene Deckplatte, Seitenwände, Stirnwände und eine Bodenplatte, lässt sich die Deckplatte relativ leicht durch die vorliegende Erfindung eines zusammengesteckten formschlüssigen Rostbodens ersetzen. Die Ausführung des Kastenelements wird einfach und erlaubt durch die offene Zugänglichkeit, insbesondere von oben, bei der Montage eine bestmögliche und leichte Befestigung auf der Tragstruktur, allgemein als Rostträger bezeichnet. Das Kastenelement wird auch nicht durch weitere seitliche Öffnungen oder herabgesetzte Stirnwände statisch geschwächt.Especially for all closed grate plates that have a box-like structure, i.e. a cover plate provided with blow-out openings, side walls, end walls and a base plate, the cover plate can be replaced relatively easily by the present invention of an interlocking form-fitting grate floor. The design of the box element is simple and, due to the open accessibility, in particular from above, when mounting, the best possible and easy attachment to the support structure, generally referred to as a grate support. The box element is also not statically weakened by further lateral openings or lowered end walls.
Insbesondere bei Verwendung für einen ebenen Rostboden wo die Zugänglichkeit seitlich nicht gegeben ist, ist eine Montage ausschließlich von oben besonders vorteilhaft. Außerdem ist die Ausgestaltung der Tragstruktur zur Aufnahme eines Rostbodens gemäß der vorliegenden Erfindung vielseitiger und kostengünstiger möglich. Auch kann die Befestigung des Rostbodens beispielsweise über eine Zentralverriegelung mittels Welle, wie in der anliegenden Zeichnung beschrieben, oder über eine vertiefte und somit geschützte Befestigung von oben erfolgen.Especially when used for a flat grate floor where there is no access from the side, installation from above is particularly advantageous. In addition, the configuration of the support structure for receiving a grate floor according to the present invention is possible in a more versatile and cost-effective manner. The grate floor can also be fastened, for example, via a central locking device by means of a shaft, as described in the attached drawing, or via a recessed and thus protected fastening from above.
Der Verschleiß durch die mechanische Förderung und die daraus resultierende Komprimierung sowie der Verschleiß durch Friktion einerseits und die thermische Belastung durch das Fördergut andererseits, erfordert einen ausgewogenen Kompromiss bei der Wahl der Materialien für den die Rostoberfläche bildenden Rostboden. Die Reduzierung der Verschleißteile auf die ausschließlich mit dem Fördergut in Kontakt stehenden Anlageflächen ist besonders vorteilhaft, da an das Material für den Rostboden andere Anforderungen als an die Tragstruktur gestellt werden und die Verschleißteilmasse reduziert wird.The wear caused by mechanical conveyance and the resulting compression, the wear caused by friction on the one hand, and the thermal load caused by the material being conveyed, on the other hand, require a balanced compromise in the choice of materials for the grate floor that forms the grate surface. The reduction of wear parts to that exclusively with the Contact surfaces to be conveyed are particularly advantageous, since the material for the grate floor is subject to different requirements than the support structure and the mass of wear parts is reduced.
Die vorliegende Erfindung reduziert die Verschleißteile durch Trennung von Rostboden und Tragstruktur und je nach Einsatzfall werden die Verbindungselemente von Rostboden und Tragstruktur vollständig geschützt und gelten nicht mehr als Verschleißteile.The present invention reduces the wear parts by separating the grate floor and support structure and, depending on the application, the connecting elements of the grate floor and support structure are completely protected and are no longer considered wear parts.
Eine besonders vorteilhafte Ausgestaltung der vorliegenden Erfindung wird dadurch geschaffen, dass die allgemein stark thermisch- und verschleißbehaftete Rostoberfläche im wesentlichen aus identischen und somit kostengünstigeren Lamellenkörpern gebildet wird. Dieser hohe Gleichteileanteil ist auch hinsichtlich der Lagerhaltung besonders vorteilhaft.A particularly advantageous embodiment of the present invention is created in that the generally highly thermally and wear-prone grate surface is essentially formed from identical and therefore more cost-effective slat bodies. This high proportion of identical parts is also particularly advantageous with regard to warehousing.

Am Lamellenhinterteil (3) sind seitlich Gegenprofile (5) angearbeitet.1, 2 and 3 show a Lamellenköφer (1) according to the present invention. The slat body (1) consists of a slat front part (2) forming the grate surface and a slat rear part (3) covered by the previous slat body. Profiles (4) are arranged laterally on the lamella front part (2) forming the grate surface. Counter profiles (5) are machined on the side of the slat rear part (3).
Fig. 4 zeigt ein Lamellenpaket (6), bestehend aus zwei Lamellenkörpern (1 ). Ein dritter Lamellenköφer (7) befindet sich vor dem Lamellenpaket (6). Die Profile (4) und die Gegenprofile (5) sind so geformt und angeordnet, dass die Lamellenkörper (1) ineinandergeschoben werden können. Vorteiihafterweise entsteht beim Ineinanderschieben von Profil (4) und Gegenprofil (5) eine gerade, ebene Rostoberfläche.Fig. 4 shows a plate pack (6) consisting of two plate bodies (1). A third slat body (7) is located in front of the plate pack (6). The profiles (4) and the counter profiles (5) are shaped and arranged in such a way that the lamellar bodies (1) can be pushed into one another. Advantageously, when the profile (4) and counter profile (5) are pushed together, a straight, level grate surface is created.
Fig. 5 zeigt eine typische Rostoberfläche (8). Die Rostoberfläche (8) wird gebildet durch hintereinander angeordnete einzelne Lamellenkörper (1 ). Unterhalb der Lamellenkörper (1) befindet sich ein kastenförmiger Lamellenträger (9), ähnlich dimensioniert und befestigt wie beispielsweise eine übliche moderne Rostplatte. Eine der Erfindung zugrunde liegende Möglichkeit zum Bau einer Rostplatte besteht darin, die zu einem Lamellenpaket (6) zusammengesteckten Lamellenkörper (1 ) auf einem kastenförmigen Lamellenträger (9) zu befestigen, indem einige Lamellenkörper (1 ) beidseitig Laschen (10) aufweisen, die mit entsprechenden Laschen (11 ) im Lamellenträger (9) fluchten und über Wellen (12), die durch die Lamellenträgerstimwände (13) eingeschoben werden, Lamellenkörper (1) und Lamellenträger (9) miteinander verbinden. Die Öffnungen für die Wellen (12) in den Lamellenträgerstirnwänden (13) werden vorzugsweise durch einstellbare Frontplatten zur Reduzierung der Schubspalte verschlossen und somit die Wellen (12) gegen herausfallen gesichert.Fig. 5 shows a typical grate surface (8). The grate surface (8) is formed by individual lamella bodies (1) arranged one behind the other. Below the slat body (1) there is a box-shaped slat carrier (9), dimensioned and fastened in a similar way to, for example, a conventional modern grate plate. One possibility for the construction of a grate plate on which the invention is based is to fasten the slat bodies (1), which are put together to form a slat package (6), on a box-shaped slat carrier (9), in that some slat bodies (1) have straps (10) on both sides, which have Align the corresponding tabs (11) in the disk carrier (9) and connect the disk body (1) and disk carrier (9) to one another using shafts (12) that are inserted through the disk carrier end walls (13). The openings for the shafts (12) in the slat carrier end walls (13) are preferably closed by adjustable front plates to reduce the shear gaps and thus the shafts (12) are secured against falling out.
Fig. 6,7 und 8 zeigen, wie mit einer Erfindung der im Patentanspruch 1 und 2 genannten Art ein ebener Rostboden aufgebaut werden kann. Vorteilhafterweise kann ein solcher Rostboden auch mit einer Zentralverriegelung versehen sein. Am Lamellenträger (9) sind auf jeder Seite Laschen (14) angebracht. Die Augen dieser Laschen befinden sich in einer Flucht. In die Laschenaugen wird eine Welle (15) hinein geschoben. Diese Welle (15) ist an einer Seite bearbeitet und weist deshalb eine Fläche (16) auf. Zur Montage werden die Wellen (15) so gedreht, dass die Fläche (16) zu den jeweiligen Außenseiten des Lamellenträgers (9) weist. Die zu befestigenden Lamellenkörper (22) sind an den Seiten mit Schwertern (17) versehen. Diese Schwerter (17) sind unten breiter ausgeführt. In der Wellenposition, in der die Flächen (16) nach außen weisen, lassen sich die Lamellenköφer (22) auf den Lamellenträger (9) auflegen. Durch verdrehen der Wellen (15) werden die Lamellenköφer (22) fixiert. Auf diese Weise lässt sich ein beliebig langer Rostboden aufbauen. Fig. 8 zeigt einen Schnitt der Fig. 76, 7 and 8 show how an even grate floor can be built up with an invention of the type mentioned in patent claims 1 and 2. Such a grate floor can advantageously also be provided with a central locking system. Tabs (14) are attached to the plate carrier (9) on each side. The eyes of these tabs are in alignment. A shaft (15) is inserted into the tab eyes pushed into it. This shaft (15) is machined on one side and therefore has a surface (16). For assembly, the shafts (15) are rotated so that the surface (16) faces the respective outer sides of the disk carrier (9). The slat bodies (22) to be fastened are provided with swords (17) on the sides. These swords (17) are made wider at the bottom. In the shaft position, in which the surfaces (16) point outwards, the lamellar bodies (22) can be placed on the lamellar carrier (9). By rotating the shafts (15), the lamella body (22) is fixed. In this way, any length of grate floor can be built. 8 shows a section of FIG. 7
Fig. 9 zeigt eine weitere vorteilhafte Ausgestaltung der Erfindung. Bei dieser Ausführung ist das Führungsprofil (18) offen. Das Lamellenhinterteil (19) fungiert gleichsam als Gegenprofil (20). Eine formschlüssige Verbindung entsteht durch das seitliche Aufschieben eines Lamellenköφers (21 ) auf den vorherigen Lamellenkörper (23).9 shows a further advantageous embodiment of the invention. In this version, the guide profile (18) is open. The slat rear part (19) acts as a counter profile (20). A positive connection is created by pushing a slat body (21) onto the previous slat body (23).
