Abstract

In a plant for cooling bulk materials, for example clinker, on grids traversed transversally by cooling air, it is intended to improve the cooling air distribution to the bulk materials and to take into account the segregation of the coarse portion and the fine portion of the bulk material. To this effect, the bulk material (3) is brought to a stationary grid (8) by a moving conveyor means arranged directly on top. In order to make the grid (8) sufficiently stable to accept the crushing forces and to enable the crushing of the aggregate coming out of the furnace by means of a crushing jaw (5) against the grid so as to enhance the cooling and dumping thereof, there is provided as a conveyor means an endless dredger chain (6) provided with transport drivers and combinable with a dam intended to dam the upper layers of the bulk material.

Description

Vorrichtung zum Kühlen von Schüttgütern wie Zementklinker Device for cooling bulk materials such as cement clinker

Gebiet der ErfindungField of the Invention

Die Erfindung betrifft eine Vorrichtung zum Kühlen von auf von einem Kühlmedium quer durchströmten Rosten geförderten, aus in Drehöfen erbrannten Schüttgütern, wie Zementklinker.The invention relates to a device for cooling materials, such as cement clinker, which are conveyed to grates, through which a cooling medium flows, and which are produced in rotary furnaces.

Stand der Technik.State of the art.

Rostkühler werden als Wanderroste oder als Schubroste mit gegeneinander beweglichen Rostreihen gebaut. In den DE-Patentanmeldungen 31 31 514.3 und 31 48 792.0 sind Maßnahmen zur besseren Luftführung und -Verteilung im Schüttgut vorgeschlagen. In besondere bei hohen Rostbetten zur Erzielung hoher Aufheizung de Kühliuft werden hohe Anforderungen an den Rost zur Gleichverteilung der Kühlluft in das darüber befindliche Schüttgut gestellt, wobei gleichzeitig hohe Drücke des Kühlmediums aufgebaut werden müssen.Grate coolers are built as traveling grates or as sliding grates with grate rows that can move against each other. DE patent applications 31 31 514.3 and 31 48 792.0 propose measures for better air guidance and distribution in the bulk material. In particular with high grate beds to achieve high heating de cooling air, high demands are placed on the grate for uniform distribution of the cooling air into the bulk material above, while at the same time high pressures of the cooling medium must be built up.

Die Dichtung der Spalte zwischen den einzelnen, beweglichen Rostplatten sowie die Dichtung der Luftkamraern gegen den bewegten Rost ist bei diesen Rostkühlern nur sehr schwierig durchzuführen.The sealing of the gaps between the individual, movable grate plates and the sealing of the air chambers against the moving grate is very difficult to carry out with these grate coolers.

Ferner macht es bei einem beweglichen Rost größere bauliche Schwierigkeiten, ihn beispielsweise so zu verstärken, daß er die Brechkräfte der Stauvorrichtung gemäß der DE-Patentanmeldung 31 31 514.3 aufnehmen kann.Furthermore, it makes greater structural difficulties with a movable grate, for example, to reinforce it so that it can absorb the refractive powers of the storage device according to DE patent application 31 31 514.3.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt daher die Aufgabe zugrunde, die Verteilung der Kühlluft auf das Schüttgut, insbesondere bei einem hohen Schüttguttbett, sicherzustellen, um so den Rekuperationsgrad zu erhöhen. Dabei ist der Entmischung des Grob- und des Feinanteils des überwiegend aus Drehöfen aufgegebenen Schüttguts Rechnung zu tragen.The invention is therefore based on the object of distributing the cooling air to the bulk material, particularly at a high level Bulk material bed, so as to increase the degree of recuperation. The segregation of the coarse and the fine fraction of the bulk material, which is mainly discharged from rotary kilns, must be taken into account.

Lösung und VorteileSolution and advantages

Diese Aufgabe wird bei einer Vorrichtung der eingangs beschriebenen Art dadurch gelöst, daß der Rost stationär und dicht gegen ungewollte Kühlmediumsdurchtritte ausgebildet ist und sich unmittelbar über ihm ein beweglisches Fördermittel befindet.This object is achieved in a device of the type described in the introduction in that the grate is stationary and tight against unwanted cooling medium penetrations and a movable conveying means is located directly above it.

Während Schub- und Wanderroste sowohl die Förderung des Schüttgutes als auch - unterstützt von Luftkammern - die Verteilung der Kühlluft in das Rostbett übernehmen müssen, ergeben sich aus der vorgeschlagenen Trennung von Förderung und Luftverteilung und deren Wahrnehmung durch verschiedene Baugruppen eine Reihe eentscheidender Vorteile.While pushing and moving gratings have to take over both the conveyance of the bulk material and - supported by air chambers - the distribution of the cooling air into the grate bed, the proposed separation of conveying and air distribution and their perception by different assemblies result in a number of decisive advantages.

In besonders vorteilhafter Weise läßt sich die Aufgabe mit stationär und durchgehend glatt verlegten Rostplatten und einer darauf gleitenden Schleppkette lösen. Diese stationären Rostplatten, die beispielsweise quer über die Kühlerbreite verlegte Lochblechstreifen sein können, lassen sich untereinander und gegen die Unterstützung wesentlich besser dichten, als es mit bewegten Rostplatten bisher möglich ist. Dadurch läßt sich der Rost technisch vorteilhaft mit einem hohen, für die gleichmäßige Verteilung der Luft wirksamen Widerstand versehen. Ebenso lassen sich die einzelnen Kammertrennwände für die Kühlluft unter dem Rost besser gegen den stationären Rost und damit untereinander dichten.The task can be solved in a particularly advantageous manner with stationary and continuously smoothly laid grate plates and a drag chain sliding thereon. These stationary grate plates, which can be perforated metal strips laid across the radiator width, for example, can be sealed much better with each other and against the support than was previously possible with moving grate plates. This allows the grate to be technically advantageously provided with a high resistance which is effective for the uniform distribution of the air. Likewise, the individual chamber partitions for the cooling air under the grate can be sealed better against the stationary grate and thus with each other.

Weiterhin lassen sich Drossel- oder Pulsierklappen dicht unter den stationären Rostplatten anordnen, um damit unmittelbar auf die Luftverteilung Einfluß zu nehmen. Schließlich können die stationären Rostplatten an der gewünschten Stelle beliebig stark ausgebildet und untersützt sein, um Brechkräfte auf den Rost aufzunehmen.Furthermore, throttle or pulsation flaps can be arranged close under the stationary grate plates in order to have a direct influence on the air distribution. Finally, the stationary grate plates can be of any desired strength and support at the desired location in order to absorb refractive forces on the grate.

Weiterbildungen der ErfindungDevelopments of the invention

Um der Entmischung, d.h. dem bevorzugten Abwurf des Fein- und des Grobanteils durch die Drehrohröfen auf je eine Seite des Rostes Rechnung zu tragen, werden nach einer weiteren Ausführungs form der Erfindung zwei oder mehrere Fördermittel - vorzugsweise handelt es sich um endlose Sσhleppenkettenförderer - nebeneinander angeordnet. Damit kann zum Zwecke der besseren Luftverteilung ein niedriges Feinanteilbett neben einem hohen Bett aus überwiegend Grobanteil eingestellt werden.To segregate, i.e. To take into account the preferred discharge of the fine and the coarse fraction by the rotary kilns on one side of the grate, according to a further embodiment of the invention, two or more conveying means - preferably it is an endless chain stair chain conveyor - arranged side by side. This means that for the purpose of better air distribution, a low fine fraction bed can be set in addition to a high bed made up of mostly coarse fraction.

Herkömmliche Rostkühler haben meist eine Schleppkette eigens zum Sammeln und Abtransport des Rostdurchfalls. Mit Vorteil kann nach einer weiteren Ausbildung der Erfindung dieser Rostdurσhfall von dem Rücklauf des endlosen Fördermittels - vorzugsweise ebenfalls einer Schleppkette - gesammelt und ggf. dem Rost wieder zugeführt werden.Conventional grate coolers usually have a drag chain especially for collecting and removing the grate diarrhea. According to a further embodiment of the invention, this rust fallout from the return of the endless conveying means - preferably also a drag chain - can be collected and possibly returned to the rust.

Die bekannten Vorteile einer steigenden oder einer fallenden Anordnung des Rostes in Förderrichtung lassen sich ebenfalls ohne weiteres mit dem stationären Rost mit Schleppkette erzielen. Im ersten Fall wird das Schüttgut unter einem erhöhten Materialbett im Bereich der Aufgabe zum Zwecke der Vergleichmäßigung über die Rostbreite ausgezogen.The known advantages of an increasing or a falling arrangement of the grate in the conveying direction can also be easily achieved with the stationary grate with drag chain. In the first case, the bulk material is drawn out from under an elevated material bed in the area of the task for the purpose of equalization across the grate width.

Im zweiten Fall wird der Schüttguttransport vom Gefälle unterstützt und kann in besonders vorteilhafter und zweckmäßiger Weise gegen eine Stauvorrichtung erfolgen, d.h. die Förderung gemäß der Erfindung erfolgt in Kombination mit dem Anstauen der oberen Schicht bzw. Schichten des Schüttgutes.In the second case, the bulk material transport is supported by the slope and can take place in a particularly advantageous and expedient manner against a stowage device, i.e. the promotion according to the invention takes place in combination with the accumulation of the upper layer or layers of the bulk material.

Soll der Feinanteil gemäß der P 31 31 514.3 teilweise verwirbelt und nach Art einer Luftförderrinne gefördert werden, so ist eine sorgfältig abgestufte Beaufschlagung des Rostes in Förderrichtung mit der Kühlluft erforderlich. Nach einem weiteren Merkmal der Erfindung wird diese Abstufung in besonders einfacher Weise durch verstellbare Öffnungen im stationären Rost erreicht. Dazu werden zwei aufeinander liegende Rostplatten mit gleicher Lochung oder Schlitzung für den Durchtritt des Kühlmediums vorgesehen, von denen die untere gegen die obere Platte verschiebbar ist, so daß sich die Öffnungen für den Durchtritt des Kühlmediums teilweise oder vollständig durch Verschieben schließen lassen.If the fine fraction is to be partially swirled in accordance with P 31 31 514.3 and conveyed in the manner of an air conveyor trough, the grate must be acted on in the conveying direction in a carefully graded manner with the cooling air required. According to a further feature of the invention, this gradation is achieved in a particularly simple manner by means of adjustable openings in the stationary grate. For this purpose, two grate plates lying one on top of the other with the same perforation or slit are provided for the passage of the cooling medium, of which the lower plate can be moved against the upper plate, so that the openings for the passage of the cooling medium can be partially or completely closed by shifting.

Weitere Vorteile und Ausbildungsmöglichkeiten der Erfindung gehen aus der nachfolgenden Beschreibung des in der schematischen Zeichnung dargestellten Ausführungsbeispiels hervor.Further advantages and training possibilities of the invention emerge from the following description of the exemplary embodiment shown in the schematic drawing.

Die Figur zeigt einen Längsschnitt durch einen horizontalen Schleppketten-Kühler mit Einlaufschacht 1, Stirnwand 2, angestautem Bett 3, ausgezogenem Bett 4, Stauwand bzw. Brechbacke 5, Schleppketten 6, Umlenk- und Antriebssternen 1 , stationärem Rost 8, den Luftkammern 9 , 10, 11 und den zugehörigen Ventilatoren 12, 13, 14.The figure shows a longitudinal section through a horizontal drag chain cooler with inlet shaft 1, end wall 2, dammed bed 3, extended bed 4, baffle wall or crushing jaw 5, drag chains 6, deflection and drive stars 1, stationary grate 8, the air chambers 9, 10 , 11 and the associated fans 12, 13, 14.

Der stationäre Rost 8 ruht auf den Rostträgern 15, die im Bereich der Luftkammer 10 unter der Stau- und Brechbacke 5 besonders eng angeordnet sind.The stationary grate 8 rests on the grate supports 15, which are arranged particularly closely in the area of the air chamber 10 under the baffle and crushing jaw 5.

Die Luftdrücke nehmen von Kammer 9 über Kammer 10 zur Kammer 11 in groben Stufen ab. Innerhalb jeder der Luftkammern 9, 10, 11 wird die Luftverteilung durch die verstellbaren Öffnungen in den stationären Rostplatten 8 vorgenommen. Die Dichtung von einer Luftkammer zur anderen im Bereich des Untertrum der Schlappkette 6 erfolgt durch Trompeten 16.The air pressures decrease from chamber 9 via chamber 10 to chamber 11 in rough steps. Inside each of the air chambers 9, 10, 11, the air is distributed through the adjustable openings in the stationary grate plates 8. The sealing from one air chamber to the other in the area of the lower run of the chain 6 is performed by trumpets 16.

Im Untertrum der Schleppkette 6 wird der Rostdurchfall zurück und um den Umlenkstern 7 gefördert, der dazu als ummantelte Trommel ausgebildet ist. Anstelle der Förderung um den Umlenkstern 7 kann der Rostdurchfäll auch mit einem kleinen Becherwerk, das nicht dargestellt ist, auf den Obertrum gefördert werden und von dort zurück in den belüfteten Kühler gelangen. In den Vorraum 17 wird Sperrluft 18 eingeblasen.In the lower strand of the drag chain 6, the grate diarrhea is conveyed back and around the deflection star 7, which is designed as a covered drum. Instead of conveying around the deflecting star 7, the grate through can also be conveyed to the upper run with a small bucket elevator, which is not shown, and from there back into the ventilated cooler. Seal air 18 is blown into the antechamber 17.

Der gekühlte und bereits vorgebrochene Klinker wird auf einen Querförderer 19 ausgetragen. The cooled and already broken clinker is discharged onto a cross conveyor 19.
