Abstract

In the invention which is, in particular, for the separation of a combustible mixture of coal, pyrite and rock refuse, the vibrating trough has a gas-permeable material bed and a material feeder and material removal elements at both ends, the heavy fraction of the bulk material being conveyed on the vibrating trough in one direction and the light fraction being fluidised and flowing off above the heavy fraction in the other direction, the separation of light and heavy material parts is to be further improved. This is achieved in that the material bed (5) is gas-impermeable at the output end (6) for the heavy fraction and in that in and/or in front of this region at least one transverse wall (7, 7', 7'') is provided to cause bulk material parts located above the heavy material layer to back up. <IMAGE>

Description

Die Erfindung betrifft eine Schwingrinne mit Fluidisiereinrichtung zur Trennung eines Schüttgutgemisches unterschiedlicher Dichte in Fraktionen mit im wesentlichen gleicher Dichte, insbesondere zur Abscheidung eines brennbaren Gemisches aus Kohle, Pyrit und Bergen, wobei die Schwingrinne eine gasdurchlässige Gutauflage (Anströ-nboden) sowie eine Gutzuführung und an den beiden Enden Gutabführungen aufweist und wobei die schwere Fraktion des Schüttgutes auf der Schwingrinne in einer Richtung gefördert wird und die leichte Fraktion fluidisiert wird und über der schweren Fraktion in der anderen Richtung abfließt.The invention relates to a vibrating trough with fluidizing device for separating a bulk material mixture of different densities into fractions with essentially the same density, in particular for separating a combustible mixture of coal, pyrite and mountains, the vibrating trough having a gas-permeable material support (inflow floor) and a material supply and the two ends have material discharges and the heavy fraction of the bulk material is conveyed on the vibrating trough in one direction and the light fraction is fluidized and flows over the heavy fraction in the other direction.

Bei einem Verfahren und einer Anlage zur Trockenabscheidung von Pyrit aus Steinkohle bzw. zur Aufbereitung von mit Pyrit beasteter Steinkohle (DE-DS 29 43 555 und DS-OS 29 43 556) ist es bekannt, eine Schrägschwingninne zu verwenden, die das dichtere Gut (d.h. die Mischung aus hauptsächlich schweren Pyrit und anwesenden zerkleinerten 3ergen) aufwärts fordert, wobei die Schwingrinne als Fluidisiereinrichtung ausgebildet ist, die das weniger dichte Gut (d.h. die noch mitgeführte zerkleinerte Kohle) abwärts fließen läßt. Die Schwingrinne dient hierbei zur Abscheidung eines brennbaren Gemisches aus einem Gemisch von Kohle, Pyrit und Bergen.In a method and a plant for the dry separation of pyrite from hard coal or for the processing of hard coal with pyrite (DE-DS 29 43 555 and DS-OS 29 43 556), it is known to use an inclined vibrating flume that the denser material ( ie the mixture of mainly heavy pyrite and the presence of crushed 3ergen) calls upwards, the vibrating channel being designed as a fluidizing device which allows the less dense material (ie the crushed coal still carried) to flow downward. The vibrating trough is used to separate a flammable mixture from a mixture of coal, pyrite and mountains.

Es sind weiterhin Vorrichoungen zur Trennung spezifisch unterschiedlich schwerer Teilchen in einem Schüttgutgemisch und zum Auslesen von schweren Beimischungen aus körnigem Schüttgut mit luftdurchströmten Schwingrinnen bekannt (DE-DS 24 S2 523 und DE-DS 24 o4 756).Devices are also known for separating particles of different weights in a bulk material mixture and for reading out heavy admixtures from granular bulk material with vibrating troughs through which air flows (DE-DS 24 S2 523 and DE-DS 24 o4 756).

Aufgabe der vorliegenden Erfindung ist es, den Trenneffekt einer Schwingrinne mit Fluidisiereinrichtung weiter zu verbessern. Diese Aufgabe wird durch die in den Patentansprüchen angegebenen Merkmale gelöst. Die Ansprüche enthalten auch Ausgestaltungen der Erfindung.The object of the present invention is to further ver the separation effect of a vibrating trough with fluidizing device improve. This object is achieved by the features specified in the patent claims. The claims also contain embodiments of the invention.

Durch die erfindungsgemäße Ausbildung der Gutauflage am Austragsende für die schwere Fraktion und die Anordnung von mindestens einer Querwand in und/oder vor diesem Bereich wird weitgehend verhindert, daß noch leichtes fluidisiertes Material in den Austragsbereich für die schwere Fraktion gelangt und von dieser mitgenommen werden kann. Es wird daher eine gegenüber dem bekannten Stand der Technik verbesserte Trennwirkung erzielt. ZweckmäBigerweise werden hierbei menrere Querwände vorgesehen, die unterschiedlich hoch ausgebildet und/oder unterschiedlich hoch über der Gutauflage angsordnet sein können. Die Querwände können auch unterschiedliche ouerschnittsformaufweisen und z.B. winkelförmig ausgesildet sein, wobei die Winkelöffnung in Fließrichtung der leichten Fraktion zeigt. Weiterhin kann es vorteilhaft sein, wenn sich der Spalt bzw. Abstand zwischen den Querwänden und der Sutauflage zum Austragsende für die schwere Fraktion verringert. Die erfindungsgemäße Schwingrinne kann sowohl norizontal angeordnet als auch als Schrägschwingrinne ausgebilcet sein, wobei in beiden Fällen auch mehrere Rinnen hintereinender vorgesehen werden können.The inventive design of the material support at the discharge end for the heavy fraction and the arrangement of at least one transverse wall in and / or in front of this area largely prevents light fluidized material from getting into the discharge area for the heavy fraction and being able to be taken away by it. An improved separation effect is therefore achieved compared to the known prior art. Expediently, smaller cross walls are provided, which can be of different heights and / or can be arranged at different heights above the product support. The transverse walls can also have different cross-sectional shapes and e.g. be angular, the angular opening pointing in the direction of flow of the light fraction. Furthermore, it can be advantageous if the gap or distance between the transverse walls and the suction pad to the discharge end for the heavy fraction is reduced. The vibrating trough according to the invention can be arranged horizontally as well as an inclined vibrating trough, wherein in both cases a plurality of troughs can also be provided one behind the other.

Die Erfindung wird in der Zeichnung an einem Ausführungsbeispiel schematisch dargestellt und in der Beschreibung näner erläutert. Die Zeichnung zeigt stark vereinfacht eine Sonrägschwingrinne mit Fluidisiereinrichtung und den erfinsungsgemäßen Merkmalen.The invention is shown schematically in the drawing using an exemplary embodiment and is explained in more detail in the description. The drawing shows, in a highly simplified manner, a Sonrägschwingrinne with fluidizing device and the features according to the invention.

Die Schrägschwingrinne 1 weist eine Gutzuführung 2, einen Luftzuführungskasten 3 mit Luftanschlüssen 3a für die Zufünrung der Fluidisierungsluft sowie eine Antriebseinrichtung 4 auf. Anstelle der Schrägschwingrinne kann auch eine horizontal angeordnete Schwingrinne vorgesehen werden. Die elastische Abstützung der Rinne, Einzelheiten der Luftzuführung, der Gutabführung sowie andere bekannte Einzelheiten sind nicht dargestellt.The inclined vibrating trough 1 has a material feed 2, an air feed box 3 with air connections 3 a for supplying the fluidizing air and a drive device 4. Instead of the inclined vibrating channel, one can horizontally arranged vibrating trough can be provided. The elastic support of the channel, details of the air supply, the material discharge and other known details are not shown.

Die Schwingrinne 1 hat eine gasdurchlässige Gutauflage (Anströmboden) 5, die sich über dem Luftzuführungskasten 3 befindet. Der Luftzuführungskasten 3 und die gasdurchlässige Gutauflege 5 erstrecken sich nur über einen Teil der Rinne. Am Austragsende 6 für die schwere Fraktion wird die Rinne nicht von Fluidisierungsluft durchströmt.The vibrating channel 1 has a gas-permeable material support (inflow floor) 5, which is located above the air supply box 3. The air supply box 3 and the gas-permeable material support 5 extend only over part of the channel. At the discharge end 6 for the heavy fraction, fluidization air does not flow through the channel.

In und vor dem nicht fluidisierten Bereich 8 der Rinne sind über der Gutauflage 5 Querwände 7, 7' und 7" angeordnet. Die Querwände sind so angebracht, da3 die schweren Gutteile zwischen den Querwänden und der Gutauflage 5, d.h. unterhalb der Querwände, hindurontreten können. Die Querwände können hierbei unterschiedlich hoch ausgebildet und/oder unterschiedlich hoch über der Gutauflage angeordnet sein, sowie gleiche oder unterschiedliche Querschnittsformen aufweisen. Sie können jedoch auch gleich ausgebildet und angeordnet sein. Es hat sich beispielsweise als zweckmäßig erwiesen, bei der Trennung eines Gemisches aus Kohle, Pyrit und Bergen, den Spalt zwischen der Querwand 7" und der Gutauflage 5 gröBer zu machen als den Spalt an der Querwand 7' und diesen wiederum größer als den Spalt an der Querwand 7.In and in front of the non-fluidized area 8 of the trough 5 transverse walls 7, 7 'and 7 "are arranged above the crop support 5. The cross walls are mounted in such a way that the heavy good parts can pass between the cross walls and the crop support 5, ie below the cross walls The transverse walls can be of different heights and / or different heights above the good support, and can have the same or different cross-sectional shapes, but they can also be of the same design and arrangement, for example, it has proven expedient to separate a mixture from Coal, pyrite and mountains to make the gap between the transverse wall 7 ″ and the material support 5 larger than the gap on the transverse wall 7 ′ and this in turn larger than the gap on the transverse wall 7.

Die Querwand 7 ist winkelförmig ausgebildet, wobei die Winkelöffnung in Fließrichtung der leichten Teile zeigt. Die Querwände 7' und 7" sind als unterschiedlich hohe ebene Staubleche ausgebildet, die senkrecht zur Gutauflage 5 bzw. zur Förderrichiung angebracht sind. Die Staubleche können auch schräg zur Gutauflage angeordnet sein.The transverse wall 7 is of an angular shape, the angular opening pointing in the direction of flow of the light parts. The transverse walls 7 'and 7 "are designed as flat baffles of different heights, which are attached perpendicular to the material support 5 or the conveying direction. The baffle plates can also be arranged obliquely to the material support.

Anstelle von drei Querwänden, wie in der Figur dargestellt, kann aucn eine andere Anzahl von Querwänden vorgesehen werden. Es ist auch möglich, lediglich eine einzelne Querwand in oder vor dem gasundurchlässigen Endbereich 6 der Schwingrinne 1 anzuordnen.Instead of three cross walls, as shown in the figure, a different number of transverse walls can also be provided. It is also possible to arrange only a single transverse wall in or in front of the gas-impermeable end region 6 of the vibrating channel 1.

An den Enden der Schwingrinne sind Staubleche 8 und.9 vorgesehen, die die schwere Fraktion (am Staublach 8) bzw. die fluidisierten leichten Gutteile (am Staublech 9) vor dem Austrag aus der Rinne anstauen, so daß hier Stauzonen entstehen. Die Staubleche können unterschiedlich hoch und fest oder in ihrer Höhe einstellbar angeordnet sein. Damit ist eine Anpassung der Schwingrinne an unteßchiadliche Materialien möglich. Es ist auch möglich, die Staubleche 8, 9 jeweils in Förderrichtung geneigt anzuordnen, so daß das zu fördernde material auf die Staubleche aufgleiten kann.At the ends of the vibrating channel, baffles 8 and 9 are provided, which accumulate the heavy fraction (on the baffle 8) or the fluidized light good parts (on the baffle 9) before they are discharged from the channel, so that congestion zones arise here. The baffle plates can be arranged at different heights and fixed or their height can be adjusted. This makes it possible to adapt the vibrating trough to non-harmful materials. It is also possible to arrange the baffle plates 8, 9 inclined in the conveying direction, so that the material to be conveyed can slide onto the baffle plates.

Des Endteil der gasunduronlässigen Gutauflage am Austragsende 6 für die schwere Fraktion kann, wie bei 10 strichpunktiert angedeutet, nach oben abgewinkelt werden. Durch die Aowinkelung 1o entstehen ähnliche Verhältnisse wie bei der Anordnung von geneigten Staublechen. Anstelle des Endteils der Gutauflage Kann auch der gesamte gasundurchlässige Teil der Gutauflage gegenüber dem gasdurchlässigen Teil leicht nach oben abgewinkelt werden.Of the end portion of the gasunduronlässigen deposit surface at the discharge 6 for the heavy fraction may, as indicated in dash-dotted lines 1 0 can be angled upwards. The angle 1o creates similar conditions as in the arrangement of inclined dust plates. Instead of the end part of the good support, the entire gas-impermeable part of the good support can also be angled slightly upwards relative to the gas-permeable part.

Bas durch die Gutzuführung 2 auf die Gutauflage 5 der Schingrinne 1 gelangende Material wird durch die schwingenden Beweguhgen der Rinne und die gleichzeitige Zuführung von Fluidisierungsluft in eine schwere und eine leichte Fraktion getrennt. Die schweren Gutanteile sinken durch das Zusammenwirken von Schwing- dzw. Förderbewegung und Fluidisierung auf die Gutauflage 5 ab. Die leichten Gutanteile werden fluidisiert und bilden oberhalb der schweren Fraktion eine Schicnt, die sich etwa wie eine Flüssigkeit verhält und auf den schweren Gutanteilen aowärts zum Austragsende am Staupoeon 9 gleitet.The material passing through the material supply 2 onto the material support 5 of the sliding channel 1 is separated into a heavy and a light fraction by the oscillating movements of the channel and the simultaneous supply of fluidizing air. The heavy portions of good decrease due to the interaction of vibrating or Conveying movement and fluidization on the product support 5. The light material portions are fluidized and form a layer above the heavy fraction, which behaves approximately like a liquid and glides on the heavy material portions as far as to the end of discharge at the Staupoeon 9.

Die Querwände 7, 7' und 7" bewirken, daß die fluidisierte Gutschicht sich nicht in Richtung auf das Austragsende für die schwere Fraktion ausbreiten kann. Von den schweren Gutteilen werden zunächst von der Gutzuführung her noch leichte Teile mitgenommen. Diese werden jedoch im Verlauf der Förderbewegung der schweren Teile fluidisiert und durch die Querwände 7, 7', 7" gehindert, sich in Richtung auf das Austragsende 6 für die schwere Fraktion auszubreiten. Zwischen den Querwänden können sich hierbei Verdichtungszonen bilden. Die fluidisierten leichten Materialanteile können über die Querwände hinweg zum Austragsende für die leichte Fraktion ebflieBen.The transverse walls 7, 7 'and 7 "have the effect that the fluidized material layer cannot spread towards the discharge end for the heavy fraction. Light parts of the heavy material parts are initially carried along by the material supply The conveying movement of the heavy parts is fluidized and prevented by the transverse walls 7, 7 ', 7 "from spreading in the direction of the discharge end 6 for the heavy fraction. Compression zones can form between the transverse walls. The fluidized light material parts can flow over the transverse walls to the discharge end for the light fraction.

Bei der Trennung eines gemahlenen Gemisches aus Kohle, Pyrit und Bergen wird der leichtere Kohleanteil fluidisiert und an einem Ende (bei Staublech 9) der Scnwingrinne abgenommen während die aus Pyrit und Bergne bestehende schwere Fraktion durch die Schwingrinne aufwärts gefördert und am anderen Ende (dei Staublech 8) ausgetragen wird.When a milled mixture of coal, pyrite and mountains is separated, the lighter coal part is fluidized and removed at one end (at dust plate 9) of the swing channel, while the heavy fraction consisting of pyrite and mountain is conveyed upwards through the vibration channel and at the other end (dei dust plate 8) is carried out.
