Abstract

The material to be cooled is divided into a precooled lower layer (10) and an upper hot layer (11). The upper layer is separated by a device (18) which feeds it to grinding rollers (16) before being recycled as the lower layer. The bottom layer is fed to a shaft (15) where it falls onto a table (20) and is conveyed further by a movable device (22). The thickness of the bottom layer is determined by the positioning of movable wall (13). <IMAGE>

Description

Die Erfindung betrifft einen Zweischichtkühler, bei dem das Kühlgut auf einer Kühlfläche vom Kühleranfang zum Kühlerende bewegt wird, wobei in einer ersten Gutzuführzone am Kühleranfang eine obere Schicht von heißem Kühlgut auf eine untere Schicht von bereits vorgekühltem Kühlgut aufgegeben wird und am Kühlerende die beiden Schichten durch eine Trenneinrichtung voneinander getrennt werden, wobei das Gut der unteren Schicht als Fertiggut abgezogen und das Gut der oberen Schicht durch eine Transporteinrichtung als Umlaufgut zu einer zweiten Gutzuführzone am Kühleranfang zurückgeführt und dort als untere Schicht auf die Kühlfläche aufgegeben wird.The invention relates to a two-layer cooler in which the goods to be cooled on a cooling surface from the start of the cooler to The cooler end is moved, being in a first feed zone an upper layer of hot at the beginning of the cooler Chilled goods on a lower layer of pre-chilled Chilled goods are given and at the end of the cooler the two Layers separated by a separator be separated, with the goods of the lower layer as Finished goods removed and the goods of the upper layer through a transport device as a circulating good to a the second feed zone at the beginning of the cooler and placed there as the lower layer on the cooling surface becomes.

Ein Zweischichtkühler der vorstehend genannten Gattung ist beispielsweise durch die DE-C-10 97 346 bekannt. Ein derartiger Kühler hat den Vorteil, daß die Kühlfläche, die beispielsweise aus einzeln belüftbaren Rostplatten und/oder Rostplattenreihen besteht, thermisch geschont wird, indem die untere Schicht bereits vorgekühlt ist und dadurch als Schutzlage wirkt.A two-layer cooler of the type mentioned above is known for example from DE-C-10 97 346. Such a cooler has the advantage that the cooling surface, for example, from individually ventilated grate plates and / or rows of grate plates, thermal is protected by pre-cooling the lower layer and acts as a protective layer.

Eine derartige Ausführung hat jedoch den Nachteil, daß bei schwankenden Mengen des Umlaufgutes auch die Höhe der unteren Schicht ständig variiert. Dadurch ergeben sich einerseits Schwierigkeiten beim Einstellen der Trenneinrichtung am Kühlerende, so daß u.U. auch bereits ausreichend gekühltes Gut als Umlaufgut zurückgeführt wird und andererseits verändert sich die Kühlwirkung durch die unterschiedlichen Schichthöhen der unteren Schicht. However, such an embodiment has the disadvantage that in the case of fluctuating quantities of the goods in circulation, also the amount the bottom layer varies constantly. This results in on the one hand, difficulties in adjusting the Separating device at the end of the cooler, so that also already Sufficiently cooled goods are returned as circulating goods and on the other hand the cooling effect changes due to the different layer heights of the lower ones Layer.

Aus der DE-U-527 173 ist eine Vorrichtung zum Trocknen und ggf. Vorbrennen granulierten Vormaterials zum Herstellen von Zement bekannt. Diese Vorrichtung enthält einen ersten Aufgabetrichter, über den Frischgut als unterste Schicht auf einen Rost aufgebracht wird. Hinter diesem ersten Aufgabetrichter ist ein zweiter Aufgabetrichter angeordnet, der rückgeführtes Gut auf die untere Schicht des Frischgutes aufbringt. Am Ende des Rostes ist eine einstellbare Ablaufschurre vorgesehen, die einen Teil des Gutes zum zweiten Aufgabetrichter zurückführt und den anderen Teil des Gutes ableitet. DE-U-527 173 discloses a drying device and, if necessary, pre-firing granulated primary material for the production known from cement. This device contains a first hopper, over the fresh produce as bottom layer is applied to a grate. Behind this first hopper is a second hopper arranged, the returned good on the applies the lower layer of the fresh material. At the end of An adjustable drainage chute is provided, which part of the goods to the second hopper leads back and derives the other part of the good.

Der Erfindung liegt die Aufgabe zugrunde, einen Zweischichtkühler der eingangs genannten Art so auszubilden, daß der Wirkungsgrad des Kühlers verbessert wird.The invention has for its object a To design two-layer coolers of the type mentioned in the introduction that the efficiency of the cooler improves becomes.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, indem eine Stauwand vorgesehen ist, deren Unterkante einen Abstand zur Kühlfläche aufweist und der Abstand zwischen der Unterkante der Stauwand und der Kühlfläche einstellbar ist entsprechend der Höhe der unteren Schicht.This object is achieved by the characterizing Features of claim 1 solved by a Storage wall is provided, the lower edge of a distance to the cooling surface and the distance between the bottom edge the storage wall and the cooling surface is adjustable accordingly the height of the bottom layer.

Mit der erfindungsgemäßen Ausführung wird somit während des Betriebes eine gleichmäßige Höhe der unteren Schicht gewährleistet, so daß einerseits eine relativ gleichmäßige Kühlwirkung erreicht wird und andererseits die Trenneinrichtung zur Trennung der unteren und oberen Schicht fest eingestellt werden kann. Durch die Einstellbarkeit des Abstandes zwischen der Unterkante der Stauwand und der Kühlfläche kann, entsprechend der Körnung des zu kühlenden Gutes, eine optimale Höhe der unteren Schicht eingestellt werden. So erfordert feinkörniges Gut eine dünnere untere Schicht als grobkörniges Gut.With the embodiment of the invention is thus during the operation of a uniform height of the lower Layer ensures that on the one hand a relative uniform cooling effect is achieved and on the other hand the separator for separating the lower and upper Layer can be fixed. Through the Adjustable distance between the lower edge the baffle and the cooling surface can, according to the Grain of the goods to be cooled, an optimal height of the lower layer can be set. So requires fine-grained Well a thinner lower layer than a coarse one Good.

Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further refinements of the invention are the subject of subclaims.

Weitere Vorteile und Ausgestaltungen der Erfindung werden im folgenden anhand der Beschreibung eines bevorzugten Ausführungsbeispieles und der Zeichnung näher erläutert.Further advantages and refinements of the invention will be hereinafter based on the description of a preferred Embodiment and the drawing closer explained.

Der in Fig.1 in einer schematischen Gesamtansicht dargestellte Zweischichtkühler ist als Schubrostkühler ausgebildet, wobei aufeinanderfolgende Plattenreihen 1, 2 abwechselnd stationär und beweglich angeordnet sind.The shown in Figure 1 in a schematic overall view Two-layer cooler is used as a moving grate cooler formed, with successive rows of plates 1, 2 are arranged alternately stationary and movable.

Die Plattenreihen des Kühlers sind zu mehreren Gruppen 3, 4, 5 zusammengefaßt, die gesondert über Ventilatoren 6 und 7 bzw. 8, 9 mit Kühlluft beaufschlagt werden.The plate rows of the cooler are divided into several groups 3, 4, 5 summarized, the separate fans 6 and 7 or 8, 9 with cooling air.

In einer ersten Gutzuführzone am Kühleranfang wird eine untere Schicht 10 von bereits vorgekühltem Kühlgut auf die Rostfläche des Kühlers aufgegeben. Auf diese untere Schicht 10 wird eine obere Schicht 11 von heißem Kühlgut aufgebracht. Das vorgekühlte Kühlgut der unteren Schicht 10 wird über einen Schacht 12 zugeführt, der durch eine Stau- oder Bunkerwand 13 von einem Schacht 14 getrennt ist, durch den das heiße Kühlgut - beispielsweise von einem Drehrohrofen kommend - auf die untere Schicht 10 des Zweischichtkühlers aufgegeben wird.In a first feed zone at the beginning of the cooler there is a lower layer 10 of already chilled goods abandoned the grate surface of the cooler. On this lower one Layer 10 becomes an upper layer 11 of hot refrigerated goods upset. The pre-chilled goods of the lower Layer 10 is fed via a shaft 12 which through a storage or bunker wall 13 from a shaft 14 is separated, through which the hot refrigerated goods - for example coming from a rotary kiln - on the lower layer 10 of the two-layer cooler abandoned becomes.

Am Kühlerende ist zum Abzug des Gutes der unteren Schicht 10 ein Fertiggutschacht 15 vorgesehen. Weiterhin ist dort ein Brecher 16 angeordnet, dem eine Schurre 17 vorgeschaltet ist, die das Gut der oberen Schicht 11 dem Brecher 16 zuführt. Diese Schurre 17 ist dabei so flach geneigt, daß sich auf ihr eine ruhende Gutzone 18 ausbildet. Sie stellt eine Trenneinrichtung dar, die am Kühlerende die Schichten 10 und 11 voneinander trennt, indem sie das Gut der unteren Schicht 10 zurückhält und in den Fertiggutschacht 15 leitet, während das Gut der oberen Schicht 11 über die ruhende Gutzone 18 hinweggleiten kann, so daß es zum Brecher 16 gelangt.At the end of the cooler, the bottom is to be removed Layer 10 a finished goods shaft 15 is provided. Farther a crusher 16 is arranged there, the one Chute 17 is connected upstream, which is the good of the upper Layer 11 feeds the crusher 16. This chute is 17 thereby inclined so flat that there is a resting one on it Training zone 18. It provides a separation device represents the layers 10 and 11 from each other at the cooler end separates by separating the material from the lower layer 10 withholds and conducts into the finished goods well 15 while the good of the upper layer 11 over the dormant Gutzone 18 can slide away so that it to the crusher 16th reached.

Durch den Brecher 16 werden gröbere Teile des Gutes der oberen Schicht 11 zerkleinert. Nach Passieren des Brechers 16 gelangt das Gut der oberen Schicht 11 als Umlaufgut zum Kühleranfang zurück (Förderlinie 19) und wird dort als untere Schicht 10 auf die Rostfläche des Kühlers aufgegeben.The crusher 16 coarser parts of the good crushed upper layer 11. After passing the crusher 16 the material of the upper layer 11 arrives as circulating material back to the beginning of the cooler (conveyor line 19) and is there as the lower layer 10 on the grate surface of the Abandoned cooler.

Das untere Ende des Fertiggutschachtes 15 mündet mit Abstand über einer Staufläche 20 aus, die durch einen horizontal angeordneten Tisch gebildet wird. Seine Abmessungen und sein Abstand vom unteren Ende des Fertiggutschachtes 15 sind so gewählt, daß der Schüttgutkegel 21a des aus dem Fertiggutschacht 15 austretenden Fertiggutes 21 auf der Oberfläche des die Staufläche 20 bildenden Tisches innerhalb der Tischränder mündet. The lower end of the finished goods chute 15 opens out Distance over a storage area 20 from a horizontally arranged table is formed. Its dimensions and its distance from the lower end of the finished goods chute 15 are chosen so that the bulk cone 21a of the exiting from the finished goods chute 15 Finished goods 21 on the surface of the storage surface 20 forming table opens into the edges of the table.

Längs der Staufläche 20 ist ein Austragsorgan 22 in Richtung des Doppelpfeiles 23 hin- und herbeweglich. Die Hubgeschwindigkeit und die Hublänge dieses als Balken ausgebildeten Austragsorganes 22 sind veränderbar.A discharge member 22 is located in the storage surface 20 Direction of the double arrow 23 to and fro. The stroke speed and the stroke length of this as a bar trained discharge member 22 are changeable.

Die Eintrittsöffnung des Fertiggutschachtes 15 am oberen Schachtende ist durch eine als Sieb oder Rost ausgebildete Klassiereinrichtung 24 abgedeckt.The entrance opening of the finished goods chute 15 at the top The shaft end is formed by a sieve or grate Classifier 24 covered.

Das vom Austragsorgan 22 nach beiden Seiten über den vorderen und hinteren Rand der Staufläche 20 ausgetragene Fertiggut 21 wird über eine nicht veranschaulichte Einrichtung (Förderlinie 27) weitertransportiert. Gewünschtenfalls kann ein Teil des Gutes der oberen Schicht 11 nach Passieren des Brechers 16 dem Fertiggut beigemischt werden (Förderlinie 28).The from the discharge member 22 on both sides of the front and rear edge of the storage surface 20 discharged Finished goods 21 are not shown Facility (funding line 27) transported on. If desired can be part of the good of the upper Layer 11 after passing through the crusher 16 of the finished product are added (funding line 28).

Rostdurchfallgut, das zwischen den Rostplatten der festen und beweglichen Plattenreihen 1, 2 nach unten fällt, wird über eine Transporteinrichtung 29 entweder der Förderlinie 27 des Fertiggutes oder der Förderlinie 19 des Umlaufgutes zugeleitet.Rust diarrhea that is between the grate plates of the solid and movable plate rows 1, 2 down falls, either via a transport device 29 the conveyor line 27 of the finished goods or the conveyor line 19 of the goods in circulation.

Die Stauwand 13 ist im Bereich zwischen der ersten Gutzuführzone (Schacht 12) und der zweiten Gutzuführzone (Schacht 14) angeordnet, wobei zwischen deren Unterkante und der Kühlfläche ein Abstand a vorgesehen ist, der der Höhe der unteren Schicht 10 entspricht.The baffle 13 is in the area between the first goods supply zone (Shaft 12) and the second feed zone (Shaft 14) arranged, between the lower edge and a distance a is provided from the cooling surface, which corresponds to the height of the lower layer 10.

Bevor anhand der Fig.2 bis 4 die Stauwand 13 detaillierter beschrieben wird, soll zunächst die Funktion des Zweischichtkühlers gemäß Fig.1 erläutert werden. Before the dam wall 13 in more detail with reference to FIGS. 2 to 4 the function is described first of the two-layer cooler according to FIG. 1 are explained.

Die untere Schicht 10 von bereits vorgekühltem Kühlgut schützt die Rostfläche des Kühlers vor einer zu hohen thermischen Belastung sowie vor starkem Verschleiß durch das heiße Kühlgut, das die obere Schicht 11 bildet.The lower layer 10 of pre-chilled goods protects the grille surface of the cooler from too high thermal stress and heavy wear by the hot refrigerated goods that form the upper layer 11.

Am Kühlerende werden die beiden Schichten durch die von der ruhenden Gutzone 18 gebildete Trenneinrichtung voneinander getrennt. Eine Veränderung der Stärke der oberen und unteren Schicht ist durch die Einstellung der Höhenlage der Trenneinrichtung möglich. So kann beispielsweise die Höhe der ruhenden Gutzone 18 durch Verringerung der Neigung der Schurre 17 vergrößert werden (und umgekehrt). Selbstverständlich sind im Rahmen der Erfindung auch andere konstruktive Möglichkeiten zur Trennung der beiden Schichten 10, 11 möglich. Die am oberen Ende des Fertiggutschachtes 15 vorgesehene Klassiereinrichtung 24 hält größere Gutbrocken, die in der unteren Schicht 10 vorhanden sind, zurück. Diese Gutbrocken unterliegen dann entweder einer automatischen Zerkleinerung im Gut der unteren Schicht oberhalb der Klassiereinrichtung 24, oder sie gelangen in die ruhende Gutzone 18 oder in die obere Schicht 11. Im letzteren Falle passieren sie erneut den Brecher 16.At the end of the cooler, the two layers are covered by of the stationary goods zone 18 from each other Cut. A change in the strength of the top and bottom layer is by hiring the Height of the separator possible. For example the height of the dormant goods zone 18 by reducing the inclination of the chute 17 can be increased (and vice versa). Of course, within the Invention also other design options for Separation of the two layers 10, 11 possible. The most Classification device provided at the top of the finished goods chute 15 24 holds larger chunks of good in the lower layer 10 are present back. These chunks of good are then subject to either an automatic Comminution in the material of the lower layer above the Classifier 24, or they go to the dormant Good zone 18 or in the upper layer 11. In the latter If they fall, they pass crusher 16 again.

Das Fertiggut 21 staut sich auf der Staufläche 20, so daß Schüttgutkegel 21a auf der Oberfläche des die Staufläche 20 bildenden Tisches innerhalb der Tischränder münden. Unabhängig von der jeweils vorhandenen - im Betrieb evtl. wechselnden - Körnungszusammensetzung des Fertiggutes 21 wird daher die ausgetragene Gutmenge ausschließlich durch die Hubgeschwindigkeit und die Hublänge des Austragsorganes 22 bestimmt. The finished goods 21 jams on the storage surface 20, so that bulk cone 21a on the surface of the storage area 20 forming tables within the table edges flow out. Regardless of the existing one - in operation Possibly changing - grain composition of the Finished goods 21 therefore become the discharged good quantity exclusively by the lifting speed and the Stroke length of the discharge member 22 determined.

Die Erfindung wurde vorstehend am Beispiel eines Schubrostkühlers erläutert. Sie ist jedoch selbstverständlich auch bei anderen Zweischichtkühlern, insbesondere bei Zweischicht Zweischicht-Wanderrostkühlern, vorteilhaft einsetzbar.The invention was above using the example of a Chill grate cooler explained. However, it is a matter of course also with other two-layer coolers, in particular with two-layer two-layer traveling grate coolers, advantageous applicable.

Im folgenden wird anhand der Schnittdarstellungen gemäß den Fig.2 bis 4 die erfindungsgemäße Stauwand detaillierter beschrieben:The following is based on the sectional views 2 to 4 the baffle wall according to the invention in more detail described:

Die Stauwand 13 besteht im wesentlichen aus einem als Tragbalken 30 ausgebildeten Tragelement und darüber angeordneten Halterungselementen, die sowohl auf der dem Schacht 12 als auch auf der dem Schacht 13 zugewandten Seite mit einer feuerfesten Ausmauerung 32 versehen sind. Der Tragbalken 30 erstreckt sich über die gesamte Breite der Kühlfläche und ist in Seitenwänden 33a und 33b des Kühlers gehaltert.The baffle 13 consists essentially of a Support beam 30 trained support element and arranged above Bracket elements, both on the Shaft 12 as well as on the shaft 13 facing Provide side with a fireproof brickwork 32 are. The support beam 30 extends over the entire Width of the cooling surface and is in side walls 33a and 33b of the cooler.

Der Tragbalken 30 ist auf den drei mit dem Kühlgut in Berührung kommenden Seitenflächen mit Schutzsegmenten 34, 35 und 36 versehen. Das der zweiten Gutzuführzone, d.h. dem Schacht 12, zugewandte Schutzsegment 34 weist eine die Höhe der unteren Schicht 10 bestimmende Abstreifkante 34a auf. Demgegenüber ist das der ersten Gutzuführzone, d.h. dem Schacht 14, zugewandte Schutzsegment 36a als nach oben offene, zur Aufnahme von Kühlgut bestimmte Rinne ausgebildet, deren vordere Begrenzungsfläche 36a wesentlich niedriger als die mit dem Tragbalken 30 verbundene hintere Begrenzungsfläche 36b ausgebildet ist. Die Schutzsegmente 34 und 35 sind demgegenüber nach außen im wesentlichen als ebene Platten ausgebildet. The support beam 30 is on the three with the refrigerated goods in Side surfaces coming into contact with protective segments 34, 35 and 36 provided. That of the second feed zone, i.e. the protective segment 34 facing the shaft 12 has a height determining the lower layer 10 Scraper edge 34a. In contrast, this is the first Goods supply zone, i.e. the shaft 14 facing protection segment 36a as open at the top, for receiving Chilled goods are formed in the groove, the front boundary surface 36a much lower than that with the rear boundary surface connected to the support beam 30 36b is formed. Protection segments 34 and 35 on the other hand, are essentially flat Plates trained.

Die einzelnen Schutzsegmente 34, 35, 36 werden vorzugsweise aus verschleißfestem Guß hergestellt und in geeigneter Weise am Tragbalken 30 gehaltert. Die Halterung kann beispielsweise darin bestehen, daß die aus einem Stück oder aus mehreren Teilen bestehenden Schutzsegmente in einer Schwalbenschwanzführung auf den Tragbalken 30 aufgeschoben werden.The individual protection segments 34, 35, 36 are preferred Made of wear-resistant cast and in a suitable Way supported on the beam 30. The bracket can consist, for example, that the one piece or several parts Protection segments in a dovetail guide on the Support beams 30 are pushed on.

Sofern sehr heißes Kühlgut, wie beispielsweise der aus einem Drehrohrofen fallende Klinker, zu kühlen ist, ist es zweckmäßig, die Stauwand 13, d. h. den Tragbalken 30 und die Halterungselemente 31 mit einem geeigneten Kühlmittel, beispielsweise Kühlluft, zu kühlen. Wie insbesondere aus Fig.3 zu ersehen ist, sind zu diesem Zweck im Tragbalken 30 und in den Halterungselementen Kühlkanäle vorgesehen. Außerdem weist der Tragbalken 30 eine Kühllufteintrittsöffnung 37 und das oberste Halterungselement 31 eine Kühlluftaustrittsöffnung 38 auf. Die Kühlluft wird vorzugsweise mäanderförmig (Pfeile 39) durch den Tragbalken und die Halterungselemente geführt.Unless very hot refrigerated goods, such as the one from clinker falling in a rotary kiln is to be cooled it expedient, the baffle 13, d. H. the support beam 30 and the bracket members 31 with a suitable one Cooling coolant, for example cooling air. How can be seen in particular from FIG Purpose in the support beam 30 and in the mounting elements Cooling channels provided. In addition, the support beam 30 a cooling air inlet opening 37 and the top bracket member 31 a cooling air outlet opening 38. The cooling air is preferably meandering (arrows 39) through the support beam and the support elements.

Während des Betriebes setzt sich die durch das Schutzsegment 36 gebildete Rinne mit durch den Schacht 14 fallenden Gut zu. Dabei bildet sich eine schräge zu der Kühlfläche geneigte Fläche, auf der weiteres, zu kühlendes, heißes Gut auftreffen und abrutschen kann. Auf diese Weise findet die Reibung im wesentlichen innerhalb des Kühlgutes statt, so daß der Tragbalken 35 und auch das Schutzsegment 36 vor Verschleiß und übermäßiger Hitze geschützt sind.During operation, the protection segment continues 36 formed channel with through the shaft 14 falling good too. This forms an oblique to the Cooling surface inclined surface, on the other, to be cooled, hot material can hit and slide off. On in this way the friction takes place essentially within of the refrigerated goods instead, so that the support beam 35 and also the protective segment 36 from wear and excessive Are protected from heat.

Die einzelnen Schutzsegmente sind vorzugsweise austauschbar am Tragbalken angebracht, so daß insbesondere das Schutzsegment 34 mit seiner Abstreifkante 34a ausgewechselt werden kann. Es können daher auch Schutzsegmente 34 verwendet werden, deren Abstreifkante 34a einen kleineren Abstand zur Kühlfläche aufweisen, wie das durch gestrichelte Linien in Fig.2 angedeutet ist. Auf diese Weise kann die Höhe der unteren Schicht 10 an das zu kühlende Gut angepaßt werden, um eine optimale Kühlwirkung zu erreichen. So erfordert feinkörniges Gut eine dünnere untere Schicht 10 als grobkörniges Gut.The individual protection segments are preferably interchangeable attached to the support beam, so that in particular the protective segment 34 is replaced with its stripping edge 34a can be. Protection segments can therefore also be used 34 are used, the stripping edge 34a have a smaller distance to the cooling surface, such as which is indicated by dashed lines in Fig.2. In this way, the height of the lower layer 10 can increase the goods to be cooled are adjusted to an optimal To achieve cooling effect. So requires fine-grained goods a thinner lower layer 10 as a coarse grain.
