Description

Die Erfindung bezieht sich auf ein Fördersieb zum Reinigen von stückigem Gilt, z. B. von stückiger Kohle mit einer Korngröße von etwa 8o bis 25o mm, welche in einer Schwimm- und Sinkanlage aufbereitet Wurde.The invention relates to a conveyor screen for cleaning lumpy Applies, e.g. B. of lumpy coal with a grain size of about 8o to 25o mm, which Was prepared in a swimming and sinking system.

Zii diesem Zweck sind Siebe bekannt, die eine ebene Siebfläche besitzen und bei denen oberhalb der Siehe Brausen zum Abspülen und WiedergUwini1cil voll Beschwerungsstoff angeordnet sind.For this purpose, sieves are known which have a flat sieve surface and for those above the See shower heads for rinsing and re-gUwini1cil full Weighting material are arranged.

Unl einen zu großen Abtrieb der Kohle zu vermeiden, wählt man zweckmäßig bei diesen Sieben nur einen verhältnismäßig geringen Förderhub. Dabei rutschen aber die meisten Stücke nur auf c,illcl- Seite über das Sieb, so daß nur die obere Suite abgebraust und vom Beschwerungsstoff, z. B. \lagnetit, befreit wird, womit große 1lagnetitverluste verbunden sind. Dieser Nachteil wird bei der Erfindung dadurch vermieden, daß das Sieb aus mehreren Stufen besteht und daß außer den über dem Sieb angebrachten Brausen noch solche zwischen den Stufen angeordnet sind, und zwar jc\Veils unter dein Ende der oberen und über dein .\lifaiig der unteren Stufe. Die zwischen den Sttifeil angebrachten Brausen vermögen das Gut bcini Fallen von den oberen auf die unteren Stufen auch von ihrer Unterseite zu spülen, wodurch der \I:t"iietitVerlust in tragbaren Grenzen bleibt.One chooses expediently in order to avoid too great a discharge of the coal with these sieves only a relatively small delivery stroke. But it slips Most of the pieces only on the c, illcl-side over the sieve, so that only the upper suite brushed off and from the weighting material, z. B. \ lagnetit, is freed, with which great 1lagnetite losses are connected. This disadvantage is thereby eliminated in the case of the invention avoided that the sieve consists of several stages and that apart from the one above the sieve attached showers are arranged between the steps, namely jc \ Veils under your end of the upper step and over your. \ lifaiig the lower step. The between The showers attached to the stalks allow the good bcini to fall from the upper ones flush the lower steps from their underside as well, thereby eliminating the loss remains within acceptable limits.

[u der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Wie in der Zeichnung zu erl;Ulillen, ruht ein Siebkasten i auf mehreren stabfiii-niigeil Letll<ern -. Durch einen Stößel 3 wird dem Siebkasten eine hilf und her gehende Bewegung Vermittelt, wodurch eine Förderung des Guts in Pfeilrichtung 4 eintritt. In dem Siehkasten ist ein mehrstufiges Sieb mit den Stufen 5, 6 und 7 abgeordnet. Über jeder Stufe befindet sich eine Brause B. Das Abbrauswasser wird in unter den Stufen allgeordneten Auffangtrichtern to aufgefangen und einem Apparat zur Wiedergewinnung des Beschweruiigsstoffes zugeführt. Zwischen den Stufen 5, 6 und 6, 7 befinden sich zusätzliche Brausen g, welche das Gilt beim Fallen von der einen Stufe zur nächsten auch von der Unterseite abbrausen.[u The drawing shows an embodiment of the invention. As can be seen in the drawing; ulillen, a sieve box i rests on several stabfiii-niigeil Letll <ern -. By means of a plunger 3, the sieve box becomes an auxiliary one Movement mediated, as a result of which the material is conveyed in the direction of arrow 4. A multi-stage sieve with stages 5, 6 and 7 is arranged in the screening box. There is a shower B above each step. The water is poured into under the Steps to all-order collecting funnels and an apparatus for recovery of the complaint substance supplied. Between levels 5, 6 and 6, 7 are located additional showers g, which apply when falling from one step to the next also rinse from the underside.

Die zwischen den Stufen angeordneten Brausen y können fest angeordnet sein. Sie können aller auch jeweils all dein oberen oder all dein unteren Sieb befestigt sein, so daß sie also die schwingende Bewegung des Siebes mitmachen. In diesem Fall muß die Brause y jeweils durch ein nachgiebiges Rohr, z. B. durch einen Gummischlauch, mit der Brauseuasserleitung Verbunden sein.The showers y arranged between the steps can be arranged in a fixed manner be. They can all also have all of your top or all of your bottom strainers attached so that they participate in the vibrating movement of the sieve. In this case the shower y must each through a flexible pipe, z. B. through a rubber hose, be connected to the shower water pipe.
