Abstract

Cooler grate plate (3) with devices for arrangement on a grate support and with passage openings (11) for cooling gas, which open on the upper side. In order that it can also be used in thermally highly loaded cooler regions, it has on the upper side of the plate at least one trough (7) for receiving and securing goods to be cooled which it shields from the hot goods situated above. The cooling gas passage openings (11) open inside the region occupied by the goods to be cooled, which are secured, and open in lateral surfaces (10) of the trough (7) for protection against goods to be coooled passing through. <IMAGE>

Description

Die Erfindung betrifft eine Kühlerrostplatte mit Einrichtungen zur Anbringung auf einem Rostträger und mit oberseitig mündenden Durch­trittsöffnungen für Kühlgas.The invention relates to a radiator grate plate with devices for attachment to a grate support and with openings for cooling gas opening on the upper side.

Bei Kühlern für aus einem Brennofen austretendes Brenngut, beispiels­weise Zementklinker, kommt es darauf an, daß möglichst viel Wärme aus dem Kühlgut für den Ofenprozeß zurückgewonnen wird und daß die Rostbestückung des Kühlers einer möglichst langen Betriebszeit stand­hält. Vornehmlich für den thermisch hoch beanspruchten Teil eines Kühlers sind stationäre Rostelemente bekannt (DE-PS 35 83 059), die aus einer Anzahl von Tragelementen mit annähernd horizontal vor­wiegend in Förderrichtung angeordneten Luftdurchtrittslöchern beste­hen. Für die Bestückung von Schubrosten mit beweglichen Rostplatten sind sie nicht geeignet, und der ungewollte Rostdurchfall von Feinan­teilen läßt sich insbesondere bei abgestellter Kühlluft nicht vollständig vermeiden. - Bei einem anderen bekannten Rostelement (DE-PS 33 32 592), das auch für Schubroste geeignet sein soll, sind besonders schmale, schräg nach oben verlaufende Luftschlitze vorgesehen, die auf der in Förderrichtung hinten liegenden Seite von einem nach vorn scharf zulaufenden Profil begrenzt sind, das bei einer Schubbewegung gegenüber dem Gut eine Abschäl- oder Hobelwirkung ausüben würde, so daß die empfindlichen Schlitzkanten bald ausgeschliffen wären und Klinker in den Schlitzen sich festsetzen und sie verstopfen würden. Sie haben auch den Nachteil, daß sie zur Kühlluftversorgung an kühlluft­führende Rostbalken gebunden sind, die man im allgemeinen nur im thermisch hoch beanspruchten Bereich verwendet und die im Nachkühl­bereich zu aufwendig wären. - Die Bestückung verschiedener Rostab­schnitte mit unterschiedlichen Rostelementen und Befestigungsvorrich­tungen ist aufwendig.In the case of coolers for items to be fired from a kiln, for example cement clinker, it is important that as much heat as possible be recovered from the items to be chilled for the kiln process and that the grating of the cooler withstands the longest possible operating time. Stationary grate elements are known primarily for the thermally highly stressed part of a cooler (DE-PS 35 83 059), which consist of a number of support elements with approximately horizontally arranged air passage holes in the conveying direction. They are not suitable for fitting sliding grates with movable grate plates, and the unwanted rust diarrhea of fine particles cannot be completely avoided, especially when the cooling air is switched off. - In another known grate element (DE-PS 33 32 592), which should also be suitable for sliding gratings, particularly narrow, obliquely upward-extending air slots are provided, which are delimited on the rear side in the conveying direction by a profile tapering towards the front are in a pushing motion would exert a peeling or planing effect on the material, so that the sensitive slit edges would soon be ground and clinker would get stuck in the slits and block them. They also have the disadvantage that they are tied to cooling air-carrying grate beams for the supply of cooling air, which are generally used only in the thermally highly stressed area and which would be too expensive in the post-cooling area. - The fitting of different grate sections with different grate elements and fastening devices is complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Rostplatte zu schaffen, die hohe thermische Widerstandsfähigkeit aufweist und daher für den thermisch hoch beanspruchten Bereich geeignet ist und mit einem luft­führenden Rostbalken verbunden werden kann; die aber auch im Schub­bereich beweglich angeordnet werden kann und innerhalb eines unten offenen Rosts funktionstüchtig ist, wobei Rostdurchfall und Ver­stopfungen der Kühlluftöffnungen erschwert oder ausgeschlossen sind.The invention has for its object to provide a grate plate which has high thermal resistance and is therefore suitable for the thermally highly stressed area and can be connected to an air-guiding grate beam; which, however, can also be arranged in a movable manner in the pushing area and is functional within a grate which is open at the bottom, with grate diarrhea and clogging of the cooling air openings being made more difficult or impossible.

Die erfindungsgemäße Lösung besteht darin, daß auf der Plattenober­seite wenigstens eine Mulde zum Aufnehmen und Festhalten von Kühlgut angeordnet ist und die Kühlluft-Durchtrittsöffnungen innerhalb des von dem festgehaltenen Kühlgut eingenommenen Bereichs der Mulde münden.The solution according to the invention consists in that at least one trough for receiving and holding refrigerated goods is arranged on the top of the plate and the cooling air passage openings open within the area of the trough occupied by the refrigerated goods held.

Da das in der Mulde festgehaltene Kühlgut sich gegenüber der Platte nicht oder nur wenig bewegt, findet dort kein oder nur geringer Ver­schleiß statt. Außerdem ist die Platte in diesem Bereich im Verhältnis zum heißen Klinker durch das festgehaltene Kühlgut isoliert.Since the refrigerated goods held in the trough do not move or move only slightly with respect to the plate, there is little or no wear and tear. In addition, the plate in this area is insulated from the hot clinker in relation to the hot clinker.

Zweckmäßigerweise sind mehrere Mulden vorgesehen, um das Kühlgut darin sicherer festhalten zu können.A number of troughs are expediently provided in order to be able to hold the refrigerated goods more securely therein.

Nach einem besonderen Merkmal der Erfindung münden die Öffnungen (oder wenigstens einige derselben) in Seitenflächen der Mulde, die im Betriebszustand im wesentlichen vertikal angeordnet sind. Die Durch­trittsöffnungen verlaufen darin wenigstens im mündungsnahen Bereich zweckmäßigerweise in Strömungsrichtung fallend, um zu vermeiden, daß Klinker sich in den Öffnungen feststetzt und in den Luftführungsbe­reich eindringen kann. Darüber hinaus können zu demselben Zweck die Öffnungsmündungen in bezug auf die betriebliche Vertikal­richtung überdeckt ausgeführt sein, das heißt, der oberhalb der Öff­nungsmündungen befindliche Plattenteil überragt den darunter befind­lichen. Dies bringt bei abgeschaltetem Kühlgas oder Reparaturarbeiten eine zusätzliche Sicherheit gegen Klinkerdurchfall, weil der aus dem Klinkerbett einwirkende Druck sich nicht unmittelbar auf die Öffnung fortsetzen kann.According to a special feature of the invention, the openings (or at least some of them) open into side surfaces of the trough, which in the operating state are arranged essentially vertically. The through openings run in it at least in the area near the mouth, advantageously falling in the direction of flow, in order to prevent clinker from getting stuck in the openings and being able to penetrate into the air duct area. In addition, you can do the same Purpose of the opening mouths to be covered in relation to the operational vertical direction, that is, the plate part located above the opening mouths projects above the one located below. When the cooling gas is switched off or repair work is carried out, this provides additional security against clinker diarrhea, because the pressure acting on the clinker bed cannot continue directly onto the opening.

Um ferner zu vermeiden, daß die durch die Schub-Relativbewegung zum Klinker hervorgerufenen Kräfte Klinkerteile in die Öffnungen hinein­drücken, werden die Öffnungsmündungen zweckmäßigerweise in den Seitenwänden der Mulden angeordnet, die parallel zur Richtung der Relativbewegung verlaufen, wobei sie zweckmäßigerweise schlitzförmig sind. Das Kühlgas wird diesen Öffnungen dann durch in Förderrichtung verlaufende, hohle Rippen zugeführt. Auch wenn diese nicht den Schutz einer darüber liegenden Klinkerschicht genießen, sind sie durch die innerhalb vorbeistreichende Kühlluft gut gekühlt.In order to further prevent the forces caused by the thrust relative movement to the clinker from pushing clinker parts into the openings, the opening openings are expediently arranged in the side walls of the troughs, which run parallel to the direction of the relative movement, and are expediently slit-shaped. The cooling gas is then fed to these openings through hollow ribs running in the conveying direction. Even if they do not enjoy the protection of an overlying clinker layer, they are well cooled by the cooling air flowing past.

In denjenigen Bereichen, in denen die Platte mit einem luftführenden Rostträger verbunden ist, liegt sie auf einer Oberplatte des Rostträgers auf, die ihre Luftzuführungsseite vollständig abdeckt. Infolge der dichten Verbindung zwischen der Platte und dieser Oberplatte des Rost­trägers können einzelne Abschnitte des Kühlrostes getrennt belüftet werden. Außerdem wird sichergestellt, daß alle Platten gleichmäßig mit Kühlluft versorgt werden und somit in Klinkerbettzonen vermeiden, daß die Kühlluft das Klinkerbett über den Weg des geringsten Widerstandes durchströmt und andere Bereiche und Platten zu wenig gekühlt werden. Die unterseitige Abdeckung der Platte durch die Oberplatte des Rost­trägers engt die zu den weiter vorne angeordneten Öffnungen führen­den Strömungsquerschnitte ein. Damit dennoch alle Öffnungen gleich­mäßig durchströmt werden, kann nach der Erfindung vorgesehen sein, daß die von der unterseitigen Kühlgaszuführung weiter entfernten Öffnungen einen größeren Durchschnittsquerschnitt aufweisen als die ihr näher liegenden.In those areas in which the plate is connected to an air-guiding grate carrier, it rests on an upper plate of the grate carrier that completely covers its air supply side. Due to the tight connection between the plate and this top plate of the grate carrier, individual sections of the cooling grate can be ventilated separately. It also ensures that all panels are evenly supplied with cooling air and thus in clinker bed zones avoid that the cooling air flows through the clinker bed via the path of least resistance and other areas and panels are cooled too little. The cover on the underside of the plate through the top plate of the grate carrier constricts the flow cross sections leading to the openings located further forward. So that all openings are still flowed through evenly, it can be provided according to the invention that the openings further away from the lower-side cooling gas supply have a larger average cross-section than those closer to it.

Während die Platten im stationären Bereich einfach durch Verschrau­bung mit der Rostträger-Oberplatte befestigt werden können, werden sie zur Verwendung im Rostbereich mit nach unten offener Bauweise zweckmäßigerweise so befestigt, wie dies aus der DE-PS 24 32 599 bekannt ist. Es werden dann alle Rostplatten, die im mittleren oder Endbereich der Kühlzone teils beweglich, teils unbeweglich über einer Luftkammer angeordnet sind, gemeinsam mit Kühlluft beaufschlagt.While the plates in the stationary area can simply be attached to the grate carrier top plate by screwing it conveniently attached for use in the grate area with a downward-open construction, as is known from DE-PS 24 32 599. All of the grate plates, which are arranged in the middle or end region of the cooling zone, partly movably, partly immovably above an air chamber, are then acted upon together with cooling air.

Im Schubrostbereich, in welchem die Rostplatten einander teilweise und relativ zueinander beweglich überlappen, muß Sicherheit dafür gegeben sein, daß während der Schubbewegung kein Klinker unter die jeweils überlappende Platte geblasen werden kann. Deshalb werden die die Kühlgasöffnungen enthaltenden Mulden zweckmäßigerweise nur im nicht überlappten Plattenteil angeordnet.In the sliding grate area, in which the grate plates partially overlap and move relative to one another, there must be certainty that no clinker can be blown under the respective overlapping plate during the pushing movement. Therefore, the troughs containing the cooling gas openings are expediently arranged only in the non-overlapped plate part.

Durch die erfindungsgemäße Anordnung wird nicht nur die Platte ge­schont, sondern tritt die Kühlluft aus der Mulde auch infolge der Siebwirkung des Klinkers besonders gleichmäßig verteilt in den oberen, heißen Bereich des Klinkerbetts ein.As a result of the arrangement according to the invention, not only is the plate protected, but the cooling air enters the upper, hot area of the clinker bed particularly evenly as a result of the sieving action of the clinker.

Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnungen erläutert, die vorteilhafte Ausführungsbeispiele veran­schaulicht. Es zeigen:

  • Fig. 1 einen Längsschnitt durch eine Rostanordnung im Bereich zweier Rostplatten auf stationären Rostträgern,
  • Fig. 2 eine der Fig. 1 entsprechende Darstellung mit einem beweglichen Rostträger,
  • Fig. 3 einen Querschnitt durch die Anordnung gemäß Fig. 1 gemäß Linie III-III und
  • Fig. 4 die Seitenansicht einer Variante derselben Rostplatte.
The invention is explained in more detail below with reference to the drawings, which illustrate advantageous exemplary embodiments. Show it:
  • 1 shows a longitudinal section through a grate arrangement in the area of two grate plates on stationary grate carriers,
  • 2 a representation corresponding to FIG. 1 with a movable grate carrier,
  • Fig. 3 shows a cross section through the arrangement of FIG. 1 along line III-III and
  • Fig. 4 is a side view of a variant of the same grate plate.

Gemäß Fig. 1 sind auf stationären Trägern 1, die als Luftführungska­näle ausgebildet sind, Oberplatten 2 fest angeordnet, auf denen Rostplatten 3 befestigt sind. Die Oberplatten 2 weisen zwecks besseren Anschlusses an die Ränder der Rostplatten umlaufende Vertiefungen 4 auf und sind mit den Rostplatten verschraubt.1, top plates 2 are fixedly arranged on stationary supports 1, which are designed as air guide channels, on which Grate plates 3 are attached. The upper plates 2 have recesses 4 encircling the edges of the grate plates for better connection and are screwed to the grate plates.

Die Rostplatten 3 überlappen sich im Bereich 5 und sind dort mit einer Dichtung 6 versehen. Im freiliegenden Bereich enthalten sie Mulden 7, die durch Querrippen 8 und Längsrippen 9 gebildet sind. In ihnen wird kaltes Kühlgut festgehalten, das eine Schutzabdeckung gegenüber dem darüber befindlichen, heißen Kühlgut bildet.The grate plates 3 overlap in the area 5 and are provided with a seal 6 there. In the exposed area, they contain troughs 7, which are formed by transverse ribs 8 and longitudinal ribs 9. Cold refrigerated goods are held in them, which forms a protective cover against the hot refrigerated goods located above them.

In den Seitenwänden 10 der Mulden 7 befinden sich Kühlgasdurchtritts­öffnungen 11, die in Strömungsrichtung ein wenig fallend verlaufen, um den Durchtritt von Kühlluft ins Innere der Platte zum Gaszuführungs­bereich zu erschweren. Sie sind in Längsrichtung des Rosts oder in Bewegungsrichtung des Guts schlitzförmig ausgeführt. Der oberhalb der Schlitze 11 befindliche Teil 12 der Rippen 9 ragt über die Mündungen der Schlitze 11 weiter in die Mulde 7 vor als der darunter befindliche Teil 13, so daß die Mündung der Durchtrittsöffnungen 11 überdeckt ist.In the side walls 10 of the troughs 7 there are cooling gas through openings 11 which run a little downward in the flow direction in order to make it more difficult for cooling air to pass into the interior of the plate to the gas supply area. They are slit-shaped in the longitudinal direction of the grate or in the direction of movement of the material. The part 12 of the ribs 9 located above the slots 11 protrudes further beyond the mouths of the slots 11 into the trough 7 than the part 13 located below, so that the mouth of the passage openings 11 is covered.

Unter den Rippen 9 sind Luftführungskanäle 14 vorgesehen. Ferner bilden die Muldenböden 16 einen gewissen Abstand zur Oberplatte 2 der Rostträger, so daß dazwischen ein luftführender Zwischenraum 15 ge­bildet ist. Zum Ausgleich der Strömungswiderstände in den Luftfüh­rungsbereichen 14, 16 ist der Schlitz 11′ in der vordersten Mulde (ganz rechts in Fig. 1) weiter ausgebildet als der Schlitz 11˝ in der mittleren Mulde und dieser wiederum weiter als der Schlitz 11‴ in der hintersten Mulde, die dem luftführenden Rostträger 1 am nächsten ist.Air guide channels 14 are provided under the ribs 9. Furthermore, the trough floors 16 form a certain distance from the top plate 2 of the grate carrier, so that an air-guiding intermediate space 15 is formed between them. To compensate for the flow resistance in the air duct areas 14, 16, the slot 11 'in the foremost depression (far right in Fig. 1) is formed further than the slot 11˝ in the middle depression and this in turn further than the slot 11 ‴ in the rearmost Trough that is closest to the air-carrying grate support 1.

Während Fig. 1 eine unbewegliche Rostplattenanordnung zeigt, veran­schaulicht Fig. 2 eine entsprechende Anordnung in einem Schubrost. In bekannter Weise wechseln mit feststehenden, luftführenden Rostträgern 1 bewegliche Rostträger 1′, die im Sinne des Pfeils in Längsrichtung des Rosts hin- und hergehend angetrieben sind. Dabei nimmt die Vor­derkante der zugehörigen Rostplatte 3 die strichpunktiert bei 3′ und 3˝ angedeuteten Extremstellungen ein. Damit in keinem Betriebszustand eine Mulde der rechts in der Zeichnung dargestellten Platte unter die linke Platte gelangt und dabei Kühlgut unter die linke Platte geblasen werden kann, sind die Mulden 7 auf denjenigen Bereich beschränkt, der sich stets außerhalb des Überlappungsbereichs befindet. Im übrigen gleicht die Rostplattenanordnung der Fig. 2 der unter Bezugnahme auf Fig. 1 und 3 erläuterten.1 shows an immovable grate plate arrangement, FIG. 2 illustrates a corresponding arrangement in a sliding grate. In a known manner alternate with fixed, air-guiding grate supports 1 movable grate supports 1 ', which are driven back and forth in the direction of the arrow in the longitudinal direction of the grate. The front edge of the associated grate plate 3 takes the dash-dotted at 3 'and 3˝ indicated extreme positions. So that, in no operating state, a trough of the plate shown on the right in the drawing gets under the left plate and blown chilled goods under the left plate can be, the troughs 7 are limited to that area that is always outside the overlap area. Otherwise, the grate plate arrangement of FIG. 2 is the same as that explained with reference to FIGS. 1 and 3.

Ohne Iuftführende Rostträger 1 und ohne deren Oberplatte 2 können Rostplatten der in Fig. 1 oder 2 gezeigten Art auch in demjenigen Rostbereich verwendet werden, in welchem die Kühlgaszuführung nicht individuell für jede Rostplattenreihe durch luftführende Rostträger 1 erfolgt. Die Rostplatten können dann ohne die Rostträger-Oberplatten 2 in geeigneter Weise befestigt werden. Dazu bedient man sich vorteilhaf­terweise der in Fig. 4 veranschaulichten, an sich bekannten Befesti­gungselemente, zu deren näheren Erläuterung auf den Stand der Tech­nik (DE-PS 24 32 599) verwiesen werden kann.Without air-carrying grate supports 1 and without their top plate 2, grate plates of the type shown in FIG. 1 or 2 can also be used in the grate area in which the cooling gas is not supplied individually for each grate plate row by air-guiding grate supports 1. The grate plates can then be fastened in a suitable manner without the grate support top plates 2. For this purpose, use is advantageously made of the known fastening elements illustrated in FIG. 4, for further explanation of which reference can be made to the prior art (DE-PS 24 32 599).
