Description

Die Erfindung betrifft eine Aufgabeschurre zur Aufgabe von Sintermaterial auf einen Sinterkühler sowie ein Verfahren zum Aufgeben von Sintermaterial von einem Sinterband auf einen Sinterkühler.The invention relates to a task chute for the task of sintering material on a sintered cooler and a method for applying sintered material from a sintering belt to a sintered cooler.

Zum Abkühlen eines in einer Sinteranlage erzeugten heißen, körnigen Sintermaterials wird dieses auf einen bewegten Sinterkühler aufgegeben. Dort erfolgt eine Kühlung durch einen maschinell erzeugten Luftstrom, der von unten durch das auf dem Kühlbett des Sinterkühlers abgelagerte heiße, körnige Sintermaterial geführt wird. Dabei hat die Korngrößenverteilung des körnigen Sintermaterials auf dem Kühlbett einen Einfluss auf die Effizienz der Kühlung, da die Korngrößenverteilung den dem Luftstrom entgegengesetzten Widerstand bestimmt. Ein in verschiedenen Regionen des Sintermaterials verschieden stark ausgeprägter Widerstand führt dazu, dass der Luftstrom Bereiche mit erhöhtem Widerstand nicht oder in geringerem Ausmaß durchströmt und das Sintermaterial daher nicht gleichmäßig gekühlt wird. Eine ungleichmäßige Kühlung führt dazu, dass unterschiedliche Körner des vom Sinterkühler abgeworfenen Sintermaterials unterschiedliche Temperaturen aufweisen. Körner mit Temperaturen oberhalb einer gewünschten Abwurftemperatur können Schäden an nachfolgenden, das gekühlte Sintermaterial verarbeitenden Anlagen, wie beispielsweise Förderbändern und Sieben, verursachen.For cooling a hot, granular sintered material produced in a sintering plant, this is placed on a moving sintered cooler. There is a cooling by a machine-generated air flow, which is guided from below by the deposited on the cooling bed of the sintering cooler hot, granular sintered material. The particle size distribution of the granular sintered material on the cooling bed has an influence on the efficiency of the cooling, since the particle size distribution determines the opposite resistance to the air flow. A resistance which is different in different regions of the sintered material results in that the air flow does not flow through regions of increased resistance or to a lesser extent and therefore the sintered material is not uniformly cooled. Uneven cooling causes different grains of the sintered material dropped by the sinter cooler to have different temperatures. Grains with temperatures above a desired dump temperature may cause damage to downstream equipment that processes the cooled sintered material, such as conveyors and screens.

Die horizontale und vertikale Korngrößenverteilung im Sintermaterial auf dem Kühlbett des Sinterkühlers wird durch die Aufgabeschurre, über die gebrochenes Sintermaterial vom Sinterband auf den Sinterkühler aufgegeben wird, beeinflusst. Eine herkömmliche Aufgabeschurre umfasst einen durch Seitenwände begrenzten Schacht mit einer oben liegenden Eingabeöffnung zur Eingabe des zu kühlenden körnigen Sintermaterials, und einer unten liegenden Ausgabeöffnung, durch welche das zu kühlende körnige Sintermaterial auf das Kühlbett des Sinterkühlers aufgegeben wird. Die Ausgabeöffnung befindet sich dabei zwischen Seitenwänden des Schachtes und einer abwärts geneigten Bodenplatte der Aufgabeschurre. Innerhalb des Schachtes erstreckt sich an der Eingabeöffnung ein nach unten geneigtes Eingabeleitblech, durch welches in den Schacht eingegebenem körnigem Material eine schräg abwärts führende Rutschbewegung aufgeprägt wird. Zwischen dem Eingabeleitblech und Seitenwänden der Aufgabeschurre verbleibt eine Öffnung, durch die das Sintermaterial der Schwerkraft folgend sich in Richtung Ausgabeöffnung bewegen kann. Unterhalb dieser Öffnung ist ein abwärts geneigtes Umlenkblech im Schacht angeordnet. Da das Umlenkblech eine andere Neigungsrichtung als das Eingabeleitblech besitzt, wird dem Sintermaterial-Gesamtstrom, der die Aufgabeschurre durchströmt, durch das Umlenkblech eine Rutschbewegung mit anderer Richtung aufgeprägt. Zwischen dem Umlenkblech und der dem unteren Ende des Umlenkbleches gegenüberliegenden Seitenwand des Schachtes der Aufgabeschurre verbleibt eine Öffnung, durch die sich das Sintermaterial der Schwerkraft folgend in Richtung der Auslassöffnung bewegen kann. Unterhalb dieser Öffnung ist meist die Bodenplatte angeordnet, deren Neigungsrichtung anders ist als die des Umlenkblechs. Wenn Umlenkblech und Bodenplatte jeweils einander entgegengesetzte Neigungsrichtungen haben, so ist es bekannt, dass der Sintermaterial-Gesamtstrom, welcher die Aufgabeschurre durch die Ausgabeöffnung verlässt, aufgrund von beim Passieren der Aufgabeschurre ablaufenden Segregationserscheinungen auf der Sintermaterial-Füllung der Aufgabeschurre einen sich über die Dicke des ausgegebenen Sintermaterial-Gesamtstromes erstreckenden Gradienten der Korngrößenverteilung aufweist. Dieser kann dahingehend ausgenutzt werden, dass ein sich unter der Ausgabeöffnung befindendes bewegtes Kühlbett des Sinterkühlers so beladen wird, dass die Korngröße des Sintermaterials in der Schicht auf dem Kühlbett über die Breite des Kühlbettes betrachtet überwiegend von unten nach oben abnimmt, also über die Dicke der Schicht ein Gradient der Korngrößenverteilung vorhanden ist. Eine Abnahme der Korngröße von unten nach oben ermöglicht eine effiziente Kühlung, da einem kühlenden Luftstrom, der von unten zugeführt wird, auf diese Weise beim Eintritt in die Schicht wenig Widerstand entgegengesetzt wird. Zudem ist in den Partikeln des Sintermaterials mit größerer Korngröße mehr Wärme gespeichert als in Partikeln des Sintermaterials mit kleineren Korngrößen, weshalb ein erster Kontakt des kühlenden Luftstromes mit Partikeln größerer Korngröße zu einer effizienteren Kühlung führt.The horizontal and vertical grain size distribution in the sintered material on the cooling bed of the sintering cooler is influenced by the feed chute, via which broken sintered material is fed from the sintering belt to the sinter cooler. A conventional feed chute comprises a sidewall-confined chute with an overhead input port for inputting the granular sintered material to be cooled, and a bottom discharge port through which the granular sintered material to be chilled is fed onto the cooling bed of the sinter chiller. The discharge opening is located between side walls of the shaft and a downwardly inclined base plate of the task chute. Within the shaft extends at the input opening a downwardly inclined input sheet through which in the Schacht entered granular material is an obliquely downward sliding motion is imposed. Between the input guide plate and side walls of the feed chute, there remains an opening through which the sintered material of gravity can move in the direction of the discharge opening. Below this opening, a downwardly inclined baffle is arranged in the shaft. Since the baffle has a different inclination direction than the input baffle plate, the total amount of sintered material flowing through the feed chute is impressed by the baffle with a sliding movement in a different direction. Between the deflecting plate and the side wall of the shaft of the feed chute opposite the lower end of the deflecting plate, there remains an opening through which the sintering material can move in the direction of the outlet opening following the force of gravity. Below this opening usually the bottom plate is arranged, the inclination direction is different than that of the baffle. When the baffle and bottom plate each have opposite directions of inclination, it is known that the total amount of sintered material exiting the feed chute through the discharge opening exceeds the thickness of the feed chute due to segregation phenomena occurring on passing the feed chute on the feed chute Having emitted total sintered material flow gradient extending the particle size distribution. This can be exploited to the extent that a moving cooling bed of the sinter cooler located below the discharge opening is loaded so that the grain size of the sintered material in the layer on the cooling bed across the width of the cooling bed decreases predominantly from bottom to top, ie across the thickness of the cooling bed Layer a gradient of the particle size distribution is present. A decrease in the grain size from bottom to top allows efficient cooling, as a cooling air flow, which is supplied from below, is thus opposed in this way little entry into the layer. In addition, more heat is stored in the particles of the sintered material with a larger grain size than in particles of the sintered material with smaller grain sizes, which is why a first contact of the cooling air flow with particles of larger grain size leads to more efficient cooling.

Nachteilig ist bei herkömmlichen Anlagen jedoch, dass besonders dann der Gradient der Korngrößenverteilung über die gesamte Breite des bewegten Kühlbettes sehr ungleichmäßig verläuft beziehungsweise teilweise nicht vorhanden ist, wenn sich das Sinterband weitgehend senkrecht zur der Bewegungsrichtung des Sinterkühlers an der Ausgabeöffnung bewegt. Das beruht darauf, dass grobkörnigere und damit schwerere Teilchen des Sintermaterials eine größere Bewegungsenergie in Richtung der Bewegungsrichtung des Sinterbandes als kleinere Teilchen aufweisen und entsprechend weiter vom Sinterband entfernt auf das Eingabeleitblech treffen. Das grobkörnigere Material tritt entsprechend konzentrierter in dem Bereich des entsprechenden Randes des Sintermaterial-Gesamtstromes in der Aufgabeschurre auf. Diese inhomogene Verteilung liegt auch noch auf dem Kühlbett des Sinterkühlers vor, weshalb keine gleichmäßige Kühlung des Sintermaterials durch den kühlenden Luftstrom gewährleistet ist, weil der dem Luftstrom vom Sintermaterial entgegengesetzte Widerstand über die Breite des Kühlbettes variiert.A disadvantage of conventional systems, however, that especially then the gradient of the particle size distribution over the entire width of the moving cooling bed is very uneven or partially absent when the sintering belt moves substantially perpendicular to the direction of movement of the sintering cooler at the discharge opening. This is due to the fact that coarser-grained and therefore heavier particles of the sintered material have a greater kinetic energy in the direction of the direction of movement of the sintering belt than smaller particles and accordingly strike the input guide plate further away from the sintering belt. The coarse-grained material occurs more concentrated in the region of the corresponding edge of the total sintered material flow in the feed chute. This inhomogeneous distribution is still present on the cooling bed of the sintering cooler, which is why no uniform cooling of the sintered material is ensured by the cooling air flow, because the resistance to the air flow from the sintered material varies across the width of the cooling bed.

Es ist die Aufgabe der vorliegenden Erfindung, ein Verfahren zum Aufgeben von Sintermaterial von einem Sinterband auf einen Sinterkühler mittels einer Aufgabeschurre und eine Aufgabeschurre bereitzustellen, mit denen eine gegenüber dem Stand der Technik verbesserte Gleichmäßigkeit der Korngrößenverteilung von Sintermaterial auf dem Kühlbett eines Sinterkühlers erreicht werden kann.It is the object of the present invention to provide a method for depositing sintered material from a sintering belt to a sintered cooler by means of a feed chute and a feed chute, with which a comparison of the prior art improved uniformity of the grain size distribution of sintered material can be achieved on the cooling bed of a sintered cooler ,

wherein the sintered material leaving the sintering belt is entered into the feed chute, optionally after a crushing operation,
then the sintered material is divided by distribution plates in at least two flowing in different directions sintered material streams, each stream of material sub-stream its flow direction is determined by the overflowed distribution plate,
and wherein the flow directions of the sintered material substreams In the case of the angles included in the same direction for a pair of directly adjacent sintered material substreams, the partial flow directional vector of the one sintered material substream has an obtuse angle with respect to the angle enclosed by the partial flow direction vectors with a horizontal plane includes the horizontal plane, and the partial stream flow direction vector of the other sintered material substream subtends an acute angle with the horizontal plane,
then the sintered material substreams are merged into an obliquely downflowing total sintered stream, the flow direction of which is represented by a total flow direction vector, the major horizontal components of the partial flow direction vectors being substantially perpendicular to the horizontal major component of the total flow direction vector, and wherein the sintered material Partial flows are directed in the flow direction of the total sintered material flow seen lateral edges of the total sintered material flow,
and then the total sintered material flow

Erfindungsgemäß wird das in die Aufgabeschurre eingegebene Sintermaterial zunächst in zwei in unterschiedliche Richtungen strömende Sintermaterial-Teilströme aufgeteilt. Diese Aufteilung erfolgt durch Aufgabe des Sintermaterials auf mit unterschiedlicher Neigung abwärts versehene Verteilbleche, die den Teilströmen jeweils ihre Strömungsrichtung vorgeben. Die Strömungsrichtungen der Sintermaterial-Teilströme werden durch Strömungsrichtungsvektoren dargestellt. Die Strömungsrichtungen der Sintermaterial-Teilströme unterscheiden sich dadurch, dass für direkt benachbarte Sintermaterial-Teilströme verschiedene Arten von Winkeln von den Strömungsrichtungsvektoren und einer horizontalen Ebene eingeschlossen werden. Einer der Winkel ist ein stumpfer Winkel, und der andere ist ein spitzer Winkel. Die Winkel werden dabei in derselben Richtung gemessen.According to the invention, the sintered material introduced into the feed chute is first divided into two sintering material substreams flowing in different directions. This division is carried out by abandoning the sintered material on with different inclination downward distribution plates, which dictate the flow of each sub-streams. The flow directions of the sinter material substreams are represented by flow direction vectors. The flow directions of the sintered material substreams differ in that, for directly adjacent sintered material substreams, different types of angles are included by the flow direction vectors and a horizontal plane. One of the angles is an obtuse angle and the other is an acute angle. The angles are measured in the same direction.

Die Sintermaterial-Teilströme werden zu einem Sintermaterial-Gesamtstrom zusammengeführt, wobei die Zusammenführung so erfolgt, dass die Teilströme in Richtung der beiden seitlichen Ränder des Sintermaterial-Gesamtstromes geleitet werden, wobei jeweils zumindest ein Teilstrom in Richtung je eines seitlichen Randes geleitet wird. Der durch die Zusammenführung der Sintermaterial-Teilströme entstandene Sintermaterial-Gesamtstrom strömt schräg abwärts. Seine in Strömungsrichtung betrachtet seitlichen Ränder liegen praktisch an Seitenwänden des Schachtes der Aufgabeschurre an.The sintered material substreams are combined to form a total sintered material stream, the merging being carried out in such a way that the substreams are conducted in the direction of the two lateral edges of the total sintered material flow, with at least one partial stream in each case being directed in the direction of one lateral edge. The total amount of sintered material resulting from the merging of the sintering material substreams flows obliquely downward. Its margins, viewed in the direction of flow, practically rest on sidewalls of the shaft of the feed chute.

Die Strömungsrichtung des durch Zusammenführung der Sintermaterial-Teilströme entstandenen Sintermaterial-Gesamtstromes wird durch einen Gesamtstrom-Strömungsrichtungvektor dargestellt.The flow direction of the total amount of sintered material produced by merging the sinter material substreams is represented by an overall flow direction vector.

Die Teilstrom-Strömungsrichtungsvektoren und der Gesamtstrom-Strömungsrichtungsvektor sind jeweils die Summe von in einem dreidimensionalen rechtwinkligen Koordinatensystem den drei Koordinatenachsen folgenden Vektoren, von denen zwei in einer horizontalen Ebene liegen, und einer senkrecht zu dieser Ebene steht. Die Teilstrom-Strömungsrichtungsvektoren und der Gesamtstrom-Strömungsrichtungsvektor liegen dabei in einer von einer der horizontal verlaufenden Koordinatenachse und der vertikal verlaufenden Koordinatenachse aufgespannten Ebene. Derjenige von den den drei Koordinatenachsen folgenden und in der horizontalen Ebene liegenden Vektoren, der den größeren Betrag hat, wird als horizontale Hauptkomponente eines Teilstrom- bzw. Gesamtstrom-Strömungsrichtungsvektors bezeichnet. Erfindungsgemäß stehen die horizontalen Hauptkomponenten der Teilstrom-Strömungsrichtungsvektoren weitgehend senkrecht auf der horizontalen Hauptkomponente des Gesamtstrom-Strömungsrichtungsvektors. Unter weitgehend senkrecht ist ein Winkelbereich von 90 +/- 25°, bevorzugt 90 +/- 20°, besonders bevorzugt 90 +/-15°, ganz besonders bevorzugt 90 +/- 10°, und überaus bevorzugt 90 +/- 5°, zu verstehen. Der tatsächlich gewählte Winkel hängt unter anderem vom horizontal gemessenen Abstand der Eingabeöffnung von der Ausgabeöffnung sowie der Bauhöhe der Aufgabeschurre ab.The partial flow direction vectors and the total flow direction vector are each the sum of vectors following three coordinate axes in a three-dimensional rectangular coordinate system, two of which are in a horizontal plane and one is perpendicular to this plane. The partial flow direction vectors and the total flow direction vector flow thereby lie in a plane spanned by one of the horizontal coordinate axis and the vertical coordinate axis. The one of the vectors following the three coordinate axes and lying in the horizontal plane, which has the larger amount, is called the horizontal main component of a partial flow direction vector. According to the invention, the horizontal main components of the partial stream flow direction vectors are largely perpendicular to the horizontal main component of the total flow direction vector. Below substantially perpendicular is an angular range of 90 +/- 25 °, preferably 90 +/- 20 °, more preferably 90 +/- 15 °, most preferably 90 +/- 10 °, and most preferably 90 +/- 5 ° , to understand. The actually selected angle depends inter alia on the horizontally measured distance of the input opening from the dispensing opening and the overall height of the feed chute.

Durch die erfindungsgemäßen Verfahrensschritte wird der Effekt, den eine in dem in die Aufgabeschurre eingegebenen Sintermaterial vorherrschende ungleichmäßige Verteilung von Körnern verschiedener Korngrößen auf die Korngrößenverteilung im Sintermaterial-Gesamtstrom hat, abgeschwächt. Das deshalb, weil je nachdem, mit welchem Sintermaterial-Teilstrom in die Aufgabeschurre eingegebenes Sintermaterial strömt, es zu dem einen oder dem anderen seitlichen Rand des Sintermaterial-Gesamtstromes geleitet wird. Infolgedessen häuft sich im Gegensatz zum Stand der Technik eine in einem Teilbereich des in die Aufgabeschurre eingegebenen Stromes von Sintermaterial besonders konzentriert vorhandene Korngröße nicht an einem entsprechenden seitlichen Rand des Sintermaterial-Gesamtstromes in der Aufgabeschurre an. Dabei ist der Begriff seitlicher Rand so zu verstehen, dass der durch die Zusammenführung der Sintermaterial-Teilströme entstandene Sintermaterial-Gesamtstrom in seiner Strömungsrichtung betrachtet wird, wobei der Sintermaterial-Gesamtstrom zwei Ränder, nämlich einen rechten und einen linken Rand aufweist.By the method steps according to the invention, the effect that a non-uniform distribution of grains of different grain sizes prevailing in the sintered material input into the feed chute has on the grain size distribution in the total amount of sintered material is weakened. This is because, depending on which sintered material substream is fed into the feed chute, sintered material is directed to one or the other side edge of the total sintered material flow. As a result, in contrast to the prior art, a grain size particularly concentrated in a portion of the flow of sintered material introduced into the feed chute does not accumulate at a corresponding lateral edge of the total sintered material flow in the feed chute. In this case, the term lateral edge is to be understood as meaning that the total amount of sintered material resulting from the merging of the sintering material substreams is viewed in its flow direction, the total amount of sintered material having two edges, namely a right and a left edge.

Die dann danach erfolgende Ausgabe des Sintermaterial-Gesamtstromes auf den Sinterkühler erfolgt nach zumindest einer Umkehrung seiner Strömungsrichtung durch die Bodenplatte der Aufgabeschurre.The then then taking place output of the total sintered material flow to the sinter cooler takes place after at least one reversal of its flow direction through the bottom plate of the feed chute.

Die horizontalen Hauptkomponenten der Teilstrom-Strömungsrichtungsvektoren zweier direkt benachbarter Teilströme haben bevorzugterweise entgegengesetzte Richtungen, dass heisst, sie stehen in einem Winkel von 180° zueinander. Sie können jedoch auch in einem kleineren Winkel zueinander stehen, wie etwa 175°, 170°, 165°, 160°, 155°, also in einem Winkel-Bereich von 155° bis 180°.The horizontal main components of the partial flow flow direction vectors of two directly adjacent partial flows preferably have opposite directions, that is, they are at an angle of 180 ° to each other. However, they can also be at a smaller angle to each other, such as 175 °, 170 °, 165 °, 160 °, 155 °, ie in an angle range of 155 ° to 180 °.

Nach einer bevorzugten Ausführungsform sind die Bewegungsrichtungen der Sintermaterial-Teilströme im selben Ausmaß abwärts geneigt. Sie können jedoch auch in verschiedenem Ausmaß abwärts geneigt sein, wobei sich der Winkel der Neigung um bis zu 15°, wie etwa 5°, 10°, unterscheiden kann. Der tatsächlich gewählte Winkel hängt unter anderem vom horizontal gemessenen Abstand der Eingabeöffnung von der Ausgabeöffnung sowie der Bauhöhe der Aufgabeschurre ab.According to a preferred embodiment, the directions of movement of the sinter material substreams are inclined downwardly to the same extent. However, they may also be inclined downwards to varying degrees, the angle of inclination being able to differ by up to 15 °, such as 5 °, 10 °. The actually selected angle depends among other things on the horizontally measured distance of the Input opening from the discharge opening and the height of the Aufgabeschurre from.

Ein weiterer Gegenstand der vorliegenden Anmeldung ist eine Aufgabeschurre zur Aufgabe von Sintermaterial auf einen Sinterkühler, umfassend einen durch Seitenwände begrenzten Schacht
mit einer Eingabeöffnung oben, die durch die Seitenwände des Schachtes und/oder durch von den Seitenwänden des Schachtes ausgehenden, sich in den vom Schacht umgrenzten Raum erstreckenden, Umgrenzungsblechen umgrenzt wird,
und einer Ausgabeöffnung unten,
zumindest einem innerhalb des Schachtes angeordneten Umlenkblech, welches mit zwei einander gegenüberliegenden Seitenwänden des Schachtes sowie einer diese verbindenden Seitenwand verbunden ist,
sowie einer Bodenplatte, welche mit zwei einander gegenüberliegenden Seitenwänden sowie einer diese verbindenden Seitenwand verbunden ist, wobei zwischen zumindest einer der Seitenwände des Schachtes und dem Umlenkblech ein Spalt vorhanden ist,
und sich zwischen der Bodenplatte und dem unteren Ende zumindest einer Seitenwand die Ausgabeöffnung befindet,
wobei die Bodenplatte vertikal direkt unterhalb des Spaltes zwischen Seitenwand und dem der Bodenplatte direkt benachbarten, vertikal über ihr angeordneten Umlenkblech angeordnet ist,
dadurch gekennzeichnet, dass
zwischen Eingabeöffnung und dem von der Eingabeöffnung aus gesehen in vertikaler Richtung ersten Umlenkblech innerhalb des Schachtes eine Verteilvorrichtung angeordnet ist,
umfassend zumindest zwei abwärts geneigte Verteilbleche, die derart abwärts geneigt sind, dass für die in gleicher Richtung gemessenen Winkel zwischen einer horizontalen Ebene und den Verteilblechen gilt, dass bei einem Paar direkt benachbarter Verteilbleche das eine der Verteilbleche einen stumpfen Winkel mit der horizontalen Ebene einschließt, und das andere der Verteilbleche einen spitzen Winkel mit der horizontalen Ebene einschließt,
und wobei sich jedes der Verteilbleche - von seinem höher liegenden Ende in Richtung seines tiefer liegenden Endes gesehen - in Richtung eines der Seitenränder des vertikal direkt unter ihm angeordneten Umlenkbleches erstreckt.A further subject of the present application is a feed chute for feeding sintered material onto a sintered cooler, comprising a shaft bounded by side walls
with an input opening at the top, which is delimited by the side walls of the shaft and / or by boundary walls extending from the side walls of the shaft and extending into the space defined by the shaft,
and a dispensing opening below,
at least one baffle disposed within the shaft, which is connected to two opposite side walls of the shaft and a side wall connecting them,
and a bottom plate, which is connected to two opposite side walls and a side wall connecting them, wherein between at least one of the side walls of the shaft and the baffle, there is a gap,
and the discharge opening is located between the bottom plate and the lower end of at least one side wall,
wherein the bottom plate is arranged vertically directly below the gap between the side wall and the base plate directly adjacent, vertically arranged above her baffle,
characterized in that
between the input port and the first deflector seen from the input port in the vertical direction, a distributor device is arranged within the shaft,
comprising at least two downwardly inclined distribution plates that are inclined downwards such that, for the equi-directional angle between a horizontal plane and the distribution plates, in a pair of directly adjacent distribution plates, the one of the distribution plates encloses an obtuse angle with the horizontal plane, and the other of the distribution plates subtends an acute angle with the horizontal plane,
and wherein each of the distribution plates - seen from its higher end in the direction of its lower end - extends in the direction of one of the side edges of the vertical directly below it arranged baffle.

Mit der erfindungsgemäßen Aufgabeschurre kann das erfindungsgemäße Verfahren durchgeführt werden.With the feed chute according to the invention, the method according to the invention can be carried out.

Der Schacht der Aufgabeschurre ist durch Seitenwände begrenzt und hat eine Eingebeöffnung oben sowie eine Ausgabeöffnung unten. Durch die Eingabeöffnung wird das Sintermaterial eingegeben, und durch die Ausgabeöffnung wird es ausgegeben.The chute of the feed chute is bounded by side walls and has a top entry port and a bottom exit port. The sintered material is input through the input port, and it is output through the discharge port.

Innerhalb des Schachtes ist zumindest ein Umlenkblech angeordnet. Dieses ist mit zwei einander gegenüberliegenden Seitenwänden des Schachtes verbunden, sowie mit einer diese beiden Seitenwände verbindenden Seitenwand. Die seitlichen Ränder des Umlenkbleches, die jeweils entlang der beiden einander gegenüberliegenden Seitenwände des Schachtes, mit denen das Umlenkblech verbunden ist, verlaufen, werden Seitenränder des Umlenkbleches genannt. Bevorzugt ist das Umlenkblech geneigt, und zwar abwärts geneigt, angeordnet. Dann verlaufen die von höher liegenden Ende in Richtung seines tiefer liegenden Endes gesehen seitlichen Ränder des Umlenkbleches, genannt Seitenränder, geneigt abwärts.Within the shaft at least one baffle is arranged. This is connected to two opposite side walls of the shaft, as well as with a side wall connecting these two side walls. The lateral edges of the baffle, each along the two opposite side walls of the shaft with which the baffle is connected, are called side edges of the baffle. Preferably, the baffle is inclined, downwardly inclined, arranged. Then seen from the higher end in the direction of its lower end seen lateral edges of the baffle, called side edges, inclined downwards.

Das Umlenkblech kann aber auch nicht geneigt, also in einer horizontalen Ebene, angeordnet sein. Zwischen zumindest einer der Seitenwände des Schachtes und dem Umlenkblech ist ein Spalt vorhanden, durch den in der Aufgabeschurre befindliches Sintermaterial sich der Schwerkraft folgend abwärts in Richtung Ausgabeöffnung bewegen kann. Bevorzugt befindet sich dieser Spalt am tiefer liegenden Ende des Umlenkbleches, beispielsweise zwischen dem tiefer liegenden Ende des Umlenkbleches und der Seitenwand, die der mit dem höher liegenden Ende des Umlenkbleches verbundenen Seitenwand gegenüberliegt. Wenn das Umlenkblech nicht geneigt ist, befindet sich der Spalt bevorzugt zwischen dem nicht mit einer Seitenwand des Schachtes verbundenen Ende des Umlenkbleches und der diesem Ende gegenüberliegenden Seitenwand.But the baffle can not be inclined, so arranged in a horizontal plane. Between at least one of the side walls of the shaft and the baffle there is a gap through which sintering material located in the charging chute can move downwards in the direction of the discharge opening, in accordance with gravity. Preferably, this gap is located at the lower end of the baffle, for example, between the lower end of the baffle and the side wall, which is opposite to the side wall connected to the higher end of the baffle. If the baffle is not inclined, the gap is preferably between the not connected to a side wall of the shaft end of the baffle and the side wall opposite this end.

Die Ausgabeöffnung befindet sich zwischen der Bodenplatte und dem unteren Ende zumindest einer Seitenwand. Die Bodenplatte ist mit zwei einander gegenüberliegenden Seitenwänden sowie einer diese verbindenden Seitenwand verbunden. Dabei ist die Bodenplatte vertikal direkt unterhalb des Spaltes zwischen Seitenwand und dem der Bodenplatte direkt benachbarten, vertikal über der Bodenplatte angeordneten Umlenkblech angeordnet. Bevorzugterweise ist die Bodenplatte geneigt, und zwar abwärts geneigt. Wenn sowohl Bodenplatte als auch Umlenkblech geneigt sind, ist die Bodenplatte in einer anderen Richtung als das Umlenkblech geneigt. Die Ausgabeöffnung liegt vertikal von der Eingabeöffnung aus gesehen nicht direkt unterhalb des Spaltes zwischen Seitenwand und dem der Bodenplatte direkt benachbarten, vertikal über der Bodenplatte angeordneten Umlenkblech.
Auf diese Weise wird die Bewegungsrichtung des Sintermaterial-Gesamtstromes nach Durchtritt durch den Spalt zumindest noch einmal durch die Bodenplatte verändert, bevor er durch die Austrittsöffnung aus der Aufgabeschurre austritt.The discharge opening is located between the bottom plate and the lower end of at least one side wall. The bottom plate is connected to two opposite side walls and a side wall connecting them. In this case, the bottom plate is arranged vertically directly below the gap between the side wall and the bottom plate directly adjacent, arranged vertically above the bottom plate baffle. Preferably, the bottom plate is inclined, downwards inclined. If both bottom plate and the baffle are inclined, the bottom plate is inclined in a direction other than the baffle. The discharge opening is located vertically from the input opening, not directly below the gap between the side wall and the bottom plate directly adjacent, arranged vertically above the bottom plate baffle.
In this way, the direction of movement of the total sintered material flow is at least once again changed by the bottom plate after passing through the gap, before it exits through the outlet opening from the task chute.

Unabhängig davon, ob Umlenkblech und/oder Bodenblech geneigt oder nicht sind, läuft das erfindungsgemäße Verfahren in gleicher Weise ab, denn auf einem nicht geneigten Umlenkblech und/oder Bodenblech bildet sich eine Materialschüttung aus, deren Oberfläche bestimmt durch den Schüttwinkel des Sintermaterials geneigt ist. Der Sintermaterial-Gesamtstrom strömt entlang dieser Oberfläche also auch im Fall eines nicht geneigten Umlenkbleches und/oder Bodenbleches schräg abwärts, so wie er es bei einem geneigten Umlenkblech und/oder Bodenblech tut.Regardless of whether the baffle and / or floor panel are inclined or not, the inventive method runs in the same way, because on a non-inclined baffle and / or floor plate forms a bed of material whose surface is determined by the angle of repose of the sintered material is inclined. The total amount of sintered material thus flows obliquely downward along this surface, even in the case of a non-inclined deflecting plate and / or floor plate, as it does with an inclined deflecting plate and / or floor plate.

Erfindungsgemäß ist innerhalb des Schachtes zwischen Eingabeöffnung und dem von der Eingabeöffnung aus gesehen in vertikaler Richtung ersten Umlenkblech innerhalb des Schachtes eine Verteilvorrichtung angeordnet. Diese umfasst zumindest zwei abwärts geneigte Verteilbleche. Die Verteilbleche sind derart abwärts geneigt, dass für den Winkel zwischen einer horizontalen Ebene und einem Verteilblech gilt, dass bei einem Paar direkt benachbarter Verteilbleche das eine der Verteilbleche einen stumpfen Winkel mit der horizontalen Ebene einschließt, und das andere der Verteilbleche einen spitzen Winkel mit der horizontalen Ebene einschließt. Dabei werden die Winkel zwischen der horizontalen Ebene und den Verteilblechen in der gleichen Richtung gemessen. Bevorzugterweise sind die einzelne oder alle Verteilbleche an ihrem höher liegenden Ende mit einer Seitenwand des Schachtes verbunden und erstrecken sich - von seinem höher liegenden Ende in Richtung ihres tiefer liegenden Endes gesehen - in Richtung eines der, bevorzugterweise geneigt abwärts verlaufenden, Seitenränder des vertikal direkt unter ihm angeordneten Umlenkbleches.According to the invention, a distribution device is arranged inside the shaft between the input opening and the first deflecting plate, viewed from the input opening, in the vertical direction within the shaft. This comprises at least two downwardly inclined distribution plates. The distributor plates are inclined downwards such that, for the angle between a horizontal plane and a distribution plate, in the case of a pair of directly adjacent distributor plates, one of the distributor plates encloses an obtuse angle with the horizontal plane, and the other of the distributor plates makes an acute angle with the distributor plate horizontal level. At that the angles become measured between the horizontal plane and the distribution plates in the same direction. Preferably, the single or all of the distribution plates are connected at its higher end with a side wall of the shaft and extend - seen from its higher end towards its lower end - in the direction of one, preferably inclined downwardly extending side edges of the vertical directly below he arranged deflecting plates.

Die Umlenkbleche können über ihre Längserstreckung von ihrem oberen zum unteren Ende überall die gleiche Breite aufweisen oder sich zum unteren Ende hin verschmälern.The baffles can have the same width over their longitudinal extent from their upper to lower end anywhere or narrow to the lower end.

Bevorzugterweise
liegen die senkrechten Projektionen der Verteilbleche auf eine horizontale Ebene innerhalb der senkrechten Projektion des von der Eingabeöffnung aus gesehen ersten Umlenkbleches auf dieselbe horizontale Ebene liegen.
Die Verteilbleche sind also nicht über dem Spalt zwischen Umlenkblech und Seitenwand angeordnet. Auf diese Weise ist sichergestellt, dass eingegebenes Sintermaterial nicht ohne Umlenkung durch die Verteilbleche aus der Aufgabeschurre ausgegeben werden kann.preferably,
the vertical projections of the distribution plates lie on a horizontal plane within the vertical projection of the first deflection plate seen from the input opening on the same horizontal plane.
The distribution plates are therefore not arranged over the gap between the deflecting plate and the side wall. In this way, it is ensured that input sintered material can not be output from the feed chute without deflection through the distribution plates.

Nach einer Ausführungsform
sind die Verteilbleche in gleichem Ausmaß abwärts geneigt. Dass heißt, der Betrag der Winkel, um welche die Längsachsen der Verteilbleche gegen die Horizontale abwärts geneigt sind, ist gleich. Sie können jedoch auch in verschiedenem Ausmaß abwärts geneigt sein, wobei sich der Winkel der Neigung um bis zu 15°, wie etwa 5°, 10°, unterscheiden kann. Der tatsächlich gewählte Winkel hängt unter anderem vom horizontal gemessenen Abstand der Eingabeöffnung von der Ausgabeöffnung sowie der Bauhöhe der Aufgabeschurre ab.According to one embodiment
the distribution plates are inclined downwards to the same extent. That is, the amount of the angles by which the longitudinal axes of the distributor plates are inclined downwards to the horizontal is the same. However, they may also be inclined downwards to varying degrees, the angle of inclination being able to differ by up to 15 °, such as 5 °, 10 °. The actually selected angle depends inter alia on the horizontally measured distance of the input opening from the dispensing opening and the overall height of the feed chute.

Benachbarte Verteilbleche sind in unterschiedliche Richtungen geneigt. Nach einer bevorzugten Ausführungsform
sind bei einem Paar direkt benachbarter Verteilbleche die beiden Verteilbleche des Paares in einander entgegengesetzte Richtungen geneigt. Das heißt, gegenüber einem Bezugspunkt liegt das rechte Ende eines Verteilbleches höher als sein linkes Ende, das Verteilblech ist also von rechts nach links abwärts geneigt. Ein direkt benachbarte Verteilblech hat ein höher liegendes linkes Ende, so dass es von links nach rechts abwärts geneigt ist. Die beiden Verteilbleche des Paares sind dann in einander entgegengesetzten Richtungen geneigt.Adjacent distribution plates are inclined in different directions. According to a preferred embodiment
are in a pair of directly adjacent distribution plates, the two distribution plates of the pair inclined in opposite directions. That is, with respect to a reference point, the right end of a Verteilbleches is higher than its left end, the distribution plate is thus inclined from right to left downwards. A directly adjacent distribution plate has a higher left end, so that it is inclined downwards from left to right. The two distribution plates of the pair are then inclined in opposite directions.

Es ist bevorzugt, dass
die höher liegenden Enden der Verteilbleche sich an der bezüglich der vertikalen Längserstreckung des Schachtes gleichen Stelle befinden. Sie können sich jedoch auch an bezüglich der vertikalen Längserstreckung des Schachtes verschiedenen Stellen befinden. Die tatsächlich gewählte Stelle hängt unter anderem vom horizontal gemessenen Abstand der Eingabeöffnung von der Ausgabeöffnung sowie der Bauhöhe der Aufgabeschurre ab.It is preferred that
the higher ends of the distribution plates are located at the same position relative to the vertical longitudinal extent of the shaft. However, they may also be located at different positions relative to the vertical length of the shaft. The actual selected location depends, inter alia, on the horizontally measured distance of the input opening from the dispensing opening and the overall height of the feed chute.

Die beim erfindungsgemäßen Verfahren angegebenen Beziehungen zwischen den horizontalen Hauptkomponenten der Teilstrom-Strömungsrichtungsvektoren und der horizontalen Hauptkomponente des Gesamtstrom-Strömungsrichtungsvektors gelten zumindest so lange, wie der Gesamtstrom sich auf dem von der Eingabeöffnung aus gesehen in vertikaler Richtung ersten Umlenkblech befindet.The relations between the horizontal main components of the partial flow direction vectors and the main horizontal component of the total flow direction vector are given in the method according to the invention at least as long as the total flow is located on the first deflector in the vertical direction as seen from the input port.

Im Anschluss wird die vorliegende Erfindung anhand einer schematischen Figur einer Ausführungsform beschrieben.In the following, the present invention will be described with reference to a schematic figure of an embodiment.

Figur 1 zeigt eine Schrägansicht eines Längsschnittes durch eine erfindungsgemäße Aufgabeschurre.
Der Schacht der Aufgabeschurre ist durch Seitenwände 1a, 1b, die aus den Teilen 1c' und 1c" bestehende Seitenwand 1c, sowie durch eine weitere, aufgrund des Längsschnittes nicht dargestellte Seitenwand, die zur Seitenwand 1b parallel verläuft, begrenzt. Zur besseren Übersichtlichkeit ist die Seitenwand 1b schraffiert. Die Eingabeöffnung 2 ist oben, eine Ausgabeöffnung 3 unten vorgesehen. Die Eingabeöffnung ist von den Seitenwänden ausgehenden Umgrenzungsblechen 4a, 4b, 4c sowie einem weiteren, aufgrund des Längsschnittes nicht dargestellten Umgrenzungsblech umgrenzt. Umlenkblech 5 ist innerhalb des Schachtes angeordnet. Es ist abwärts geneigt und mit der Seitenwand 1b, der nicht dargestellten zu 1b parallelen Seitenwand, sowie den Teilen 1c' und 1c" verbunden. Die von dem höher liegenden Ende des Umlenkbleches in Richtung seines tiefer liegenden Endes gesehen seitlichen Ränder, genannt Seitenränder, des Umlenkbleches verlaufen geneigt abwärts. Zwischen der Seitenwand 1a und dem Umlenkblech 5 ist ein Spalt vorhanden. Vertikal direkt unterhalb des Spaltes ist eine Bodenplatte 6 angeordnet. Die Bodenplatte 6 ist abwärts geneigt, wobei sich die Richtung der Neigung der Bodenplatte 6 von der Richtung der Neigung des Umlenkbleches 5 unterscheidet; während die in Figur 1 dargestellte Bodenplatte 6 von rechts nach links abwärts geneigt ist, ist das Umlenkblech 5 von links nach rechts abwärts geneigt. Die Bodenplatte ist mit der Seitenwand 1b, der nicht dargestellten zu 1b parallelen Seitenwand, sowie der Seitenwand 1a verbunden. Zwischen dem unteren Ende des Teils 1c" der Seitenwand 1c und der Bodenplatte 6 befindet sich die Ausgabeöffnung 3. FIG. 1 shows an oblique view of a longitudinal section through a feed chute according to the invention.
The shaft of the feed chute is bounded by side walls 1a, 1b, the side wall 1c consisting of the parts 1c 'and 1c ", as well as by a further side wall, not shown due to the longitudinal section, which runs parallel to the side wall 1b The entry opening 2 is provided at the top, and an exit opening 3 at the bottom is provided, the entry opening being from the side walls Boundaries 4a, 4b, 4c and a further, not shown due to the longitudinal section bounding plate bounded. Deflection plate 5 is arranged within the shaft. It is inclined downwards and connected to the side wall 1b, not shown, to the side wall parallel to 1b, and to the parts 1c 'and 1c. "The edges seen from the higher end of the baffle towards its lower end, called side edges, of the There is a gap between the side wall 1a and the baffle 5. Vertically directly below the nip is a bottom plate 6. The bottom plate 6 is inclined downwardly, with the direction of inclination of the bottom plate 6 being from the direction of inclination of the baffle 5, while the in FIG. 1 shown bottom plate 6 is inclined downwards from right to left, the baffle 5 is inclined downwards from left to right. The bottom plate is connected to the side wall 1b, not shown to 1b parallel side wall, and the side wall 1a. Between the lower end of the part 1c "of the side wall 1c and the bottom plate 6 is the discharge opening 3.

Zwischen der Eingabeöffnung 2 und dem Umlenkblech 5 ist eine die beiden direkt benachbarten Verteilblechen 7a und 7b umfassende Verteilvorrichtung angeordnet. Die beiden Verteilbleche 7a und 7b sind abwärts geneigt. Sie verschmälern sich zu ihrem tiefer liegenden Ende hin, wie bei Verteilblech 7b sichtbar ist. Die Verteilbleche 7a und 7b sind in voneinander verschiedenen Richtungen geneigt, nämlich in einander entgegengesetzte Richtungen. Beide Verteilbleche 7a und 7b sind im gleichen Ausmaß abwärts geneigt. Mit einer beispielsweise durch die Verteilöffnung gelegten horizontalen Ebene schließt Verteilblech 7a bei entsprechender Richtung der Winkelmessung einen spitzen Winkel ein, während Verteilblech 7b bei gleicher Richtung der Winkelmessung einen stumpfen Winkel mit derselben horizontalen Ebene einschließt. Das Verteilblech 7b ist mit seinem höher liegenden Ende mit der Seitenwand 1b verbunden, während das Verteilblech 7a mit seinem höher liegenden Ende mit der dazu parallelen nicht dargestellten Seitenwand verbunden ist. Jedes der Verteilbleche erstreckt sich in Richtung eines der geneigt abwärts verlaufenden Seitenränder des Umlenkbleches 5. Verteilblech 7a erstreckt sich in Richtung des Seitenrandes, der der Seitenwand 1b benachbart ist, und Verteilblech 7b erstreckt sich in Richtung des anderen Seitenrandes des Umlenkbleches 5. Die Verteilbleche 7a und 7b sind so angeordnet, dass ihre senkrechten Projektionen auf eine horizontale Ebene innerhalb der senkrechten Projektion des Umlenkbleches 5 auf dieselbe horizontale Ebene liegen. Die Verteilbleche 7a und 7b liegen nicht vertikal direkt über dem Spalt zwischen Umlenkblech 5 und Seitenwand 1a.Between the input port 2 and the baffle 5, a distribution device comprising the two directly adjacent distributor plates 7a and 7b is arranged. The two distribution plates 7a and 7b are inclined downwards. They narrow towards their lower end, as can be seen in distribution plate 7b. The distribution plates 7a and 7b are inclined in mutually different directions, namely in opposite directions. Both distribution plates 7a and 7b are inclined downwards to the same extent. With a horizontal plane, for example, laid through the distribution opening, distribution plate 7a encloses an acute angle in the corresponding direction of the angle measurement, while distribution plate 7b encloses an obtuse angle with the same horizontal plane in the same direction of the angle measurement. The distribution plate 7b is connected at its higher end to the side wall 1b, while the distribution plate 7a is connected at its higher end with the parallel to the side wall, not shown. Each of the distribution plates extends in the direction of one of the inclined downwardly extending side edges of the baffle 5. Distribution plate 7a extends in the direction of the side edge, which is adjacent to the side wall 1b, and distribution plate 7b extends in the direction of the other side edge of the baffle 5. The distribution plates 7a and 7b are arranged so that their vertical projections lie on a horizontal plane within the vertical projection of the baffle 5 on the same horizontal plane. The distribution plates 7a and 7b are not vertically directly above the gap between the baffle 5 and side wall 1a.

In die Aufgabeschurre eingegebenes Sintermaterial wird durch die beiden Verteilbleche 7a und 7b in zwei Sintermaterial-Teilströme aufgeteilt, die mit von den Verteilblechen 7a und 7b vorgegebenen Strömungsrichtungen in Richtung der Seitenränder des Umlenkbleches strömen. Die die Verteilbleche 7a und 7b verlassenden Sintermaterial-Teilströme werden zu einem Sintermaterial-Gesamtstrom zusammengeführt, welcher das Umlenkblech 5 hinabströmt. Die horizontalen Hauptkomponenten des Gesamtstrom-Strömungsvektors und der Teilstrom-Strömungsrichtungsvektoren stehen senkrecht aufeinander. Dem Sintermaterial-Gesamtstrom wird anschließend von der Bodenplatte eine umgekehrte Strömungsrichtung aufgezwungen, bevor das Sintermaterial durch die Ausgabeöffnung 3 auf den nicht dargestellten Sinterkühler aufgegeben wird.Sintering material introduced into the feed chute is divided by the two distribution plates 7a and 7b into two sintered material substreams which flow in the direction of the side edges of the deflection plate with flow directions predetermined by the distribution plates 7a and 7b. The sintered material substreams leaving the distribution plates 7a and 7b are combined to form a total sintered material flow, which flows down the deflection plate 5. The horizontal major components of the total flow flow vector and the partial flow flow direction vectors are perpendicular to each other. The sintered material total flow is then imposed by the bottom plate, a reverse flow direction before the sintered material is fed through the discharge opening 3 on the sintered cooler, not shown.
