Die in den Figuren 1 bis 3 dargestellte Ausführungsform einer derartigen Vorrichtung weist ein endloses Förderband 2 auf, das über Umlenkrollen 9 läuft und an Führungsrollen 7 bzw. Stützrollen 8 abgestützt ist. Durch die Führung des Förderbandes 2 ergibt sich hierbei, ausgehend von einer etwa mittleren Spannrolle aus, ein nach links verlaufender ansteigender Teil 6 und ein zur rechten Seite hin gerichteter Teil 5. Oberhalb des Förderbandes 2 befindet sich eine Aufgaberutsche 3, wobei die Fließrichtung 32 des an dem Materialaufgabebereich 11 aufgegebenen Materials entgegen der Laufrichtung 31 des Förderbandes 2 gerichtet ist. Das Förderband 2 bildet in etwa vom Bereich der Führungsrolle 7 aus zu dem Teil 5 stromabwärts der Aufgaberutsche 3 eine Waschmulde 4. Die Anordnung dieser Bauteile erfolgt an einem Maschinengestell 1, das beispielsweise auch so ausgebildet sein kann, daß es als seitliche Begrenzung für das Förderband 2 dient. Das Förderband 2 kann auch als Wellkantengurt oder durch seitliche Führungen begrenzt sein.The embodiment of a shown in Figures 1 to 3 Such device has an endless conveyor belt 2, which over Deflection rollers 9 runs and on guide rollers 7 or support rollers 8 is supported. The guidance of the conveyor belt 2 results here, starting from an approximately medium tension pulley, one after rising part 6 to the left and one to the right directed part 5. Above the conveyor belt 2 is a Feed chute 3, the flow direction 32 of the at the material feed area 11 feed material against the direction 31 of the conveyor belt 2 is directed. The conveyor belt 2 forms approximately from Area of the guide roller 7 from to the part 5 downstream of the feed chute 3 a washing trough 4. The arrangement of these components takes place on a machine frame 1, for example, also can be designed that it as a lateral boundary for the Conveyor belt 2 is used. The conveyor belt 2 can also be a corrugated edge belt or be limited by side guides.

Die gereinigten körnigen Feststoffe werden an dem ansteigenden Teil 6 des Förderbandes 2 ausgetragen, während das Feinstmaterial, d.h. das Feinkorn und auch leichte Schadstoffe an dem Teil 5 stromabwärts der Aufgaberutsche 3 ausgetragen werden. Im ansteigenden Teil 6 ist eine in Druck und Lage verstellbare Brausevorrichtung 35 vorgesehen, die zum Nachwaschen dient. Die am Teil 6 ausgetragenen körnigen Feststoffe werden in einer dynamischen Entwässerungsvorrichtung 27 entwässert, die am Maschinengestell 1 angebracht ist, wobei das Material über eine Aufgabeöffnung 28, eine Entwässerungsrinne 29 mit Spaltsiebboden zu einer Abtransportöffnung 30 gelangt.The cleaned granular solids are on the rising part 6 of the conveyor belt 2 discharged while the fine material, i.e. the fine grain and also light pollutants on the part 5 downstream the feed slide 3 are carried out. In the rising part 6 is a shower device 35 adjustable in pressure and position is provided, which is used for washing up. The grainy carried out on part 6 Solids are collected in a dynamic dewatering device 27 dewatered, which is attached to the machine frame 1, which Material via a feed opening 28, a drainage channel 29 with Slotted screen bottom reaches a discharge opening 30.

Die mit einem Rüttelmotor 12 versehene dynamische Aufgaberutsche 3 weist einen Boden 10 auf, der zunächst im Materialaufgabebereich 11 bis in etwa oberhalb des Beginns der Waschmulde als Blindboden 19 ausgebildet ist und sich dann an diesen Blindboden 19 ein einstellbarer Spalt 20 anschließt. Der weitere Bereich 21 des Bodens 10 ist mit einer Lochung versehen. Dadurch wird ein gezieltes Abregnen des aufgegebenen Materials ins Trennbett 4 ermöglicht. Weiterhin ist die Aufgaberutsche 3 im Materialaufgabebereich 11 an einer Achse 33 und im Bereich 21 der Lochung an einer Achse 34 höhenverstellbar angeordnet, so daß die Neigung verändert werden kann. Die Rutsche 3 ist auch in Längsrichtung und in der Höhe insgesamt verstellbar.The dynamic feed chute provided with a vibrating motor 12 3 has a base 10, which is initially in the material feed area 11 up to approximately above the start of the washing trough as a blind floor 19 is formed and then adjustable to this blind floor 19 Gap 20 connects. The further area 21 of the bottom 10 is with a Provide perforation. This will deliberately rain the abandoned Material into the separation bed 4 allows. Furthermore, the feed slide 3 in the material feed area 11 on an axis 33 and in the area 21 of the perforation on an axis 34 arranged height adjustable so that the inclination can be changed. The slide 3 is also in Overall length and height adjustable.

Durch diese Ausbildung der Aufgaberutsche 3 wird eine turbulente Strömung beim Absetzen des Materials vermieden, so daß Feinstmaterial am Auslauf des Teils 5 in einer Größenordnung von etwa 0 - 4 mm gewonnen werden kann.This configuration of the feed chute 3 makes it turbulent Avoid flow when settling the material, so that very fine material at the outlet of part 5 in an order of magnitude of approximately 0 - 4 mm can be obtained.

Dieser Effekt kann im wesentlichen auch dadurch ereicht werden, daß unter Verwendung einer herkömmlichen Aufgaberutsche in dem Bereich des Teiles 5 stromabwärts der Aufgaberutsche 3 ein wasserdurchlässiger Trog 15 eingetaucht wird, der mit kugeligen Körpern 16 gefüllt ist. Der Trog 15 erstreckt sich hierbei über die gesamte Breite und Tiefe, wobei die Größe der Kugeln 16 die Korngrößentrennung beeinflußt. Eine Beeinflussung ergibt sich auch durch die Oberflächenbeschaffenheit und das Gewicht der Kugeln 16. Der Trog 15 ist in der Höhe, der Neigung und Längsrichtung verstellbar, wobei eine verstellbare Aufhängung 22 (Fig. 6) vorgesehen ist.This effect can essentially also be achieved in that using a conventional feed chute in the area of part 5 downstream of the feed chute 3 a water permeable Trough 15 is immersed, which is filled with spherical bodies 16 is. The trough 15 extends over the entire width and Depth, the size of the balls 16 influencing the grain size separation. The surface properties also have an influence and the weight of the balls 16. The trough 15 is in the Height, inclination and longitudinal direction adjustable, being an adjustable Suspension 22 (Fig. 6) is provided.

Zur Verbesserung des Trenneffektes kann auch an dem Förderband 2 eine Klopfrolle 13 angeordnet sein.To improve the separation effect, it is also possible to use the conveyor belt 2 a knock roller 13 may be arranged.

Im Bereich des Feinstmaterialaustrages 18 am Ende des Teiles 5 des Förderbandes 2 ist ein Trennpaddel 17 angebracht, das die ablaufende Suspension in zwei Filmströmmungen aufteilt, wobei die obere Strömung Wasser mit leichten Schadstoffen und die untere Strömung Wasser mit Feinkorn enthält.In the area of the fine material discharge 18 at the end of part 5 of the Conveyor belt 2, a separator paddle 17 is attached, which the running Split the suspension into two film streams, the upper one Current water with light pollutants and the lower current Contains water with fine grain.

Die Vorrichtung ist am Maschinengestell 1 an der einen Seite um einen Schwenkpunkt 36 verschwenkbar und an der anderen Seite mit Hilfe einer Hebeeinrichtung 37. Damit läßt sich über eine automatische Probenahme mit Auswertung und einer entsprechenden Steuerung ein gleichmäßiges Kornband erzeugen.The device is on the machine frame 1 on one side by one Pivot point 36 can be pivoted and on the other side with the help a lifting device 37. This allows an automatic Sampling with evaluation and a corresponding control Create an even grain band.

Der Trenneffekt kann auch dadurch beeinfluß werden, daß die Förderbandoberfläche 14 einen Rauhigkeitsgrad aufweist.The separation effect can also be influenced in that the Conveyor belt surface 14 has a degree of roughness.

Bei der weiteren in Fig. 4 gezeigten Ausführungsform der Vorrichtung erfolgt die Materialaufgabe über einen Prallkasten bzw. Verteilerkasten 25, wo das Material beispielsweise mit Hilfe einer Pumpe 26 der Aufgaberutsche 3 zugeführt wird. Das Material kann auch im freien Fall zugeführt werden. Die Aufgaberutsche 3 ist hierbei eine statische Rutsche, indem ein Schwingantrieb nicht vorgesehen ist.In the further embodiment of the device shown in FIG. 4 the material is fed in via an impact box or distribution box 25, where the material, for example with the aid of a pump 26 Feed slide 3 is fed. The material can also be used outdoors Case are fed. The feed chute 3 is a static one Slide in which a vibratory drive is not provided.

Bei der Ausführungsform nach Fig. 5 ist das Förderband 2 im Bereich des ansteigenden Teiles 6 verlängert, um eine verbesserte Entwässerung des dort ausgetragenen Materials zu erreichen, indem in diesem Bereich ein Verdichtungsaggregat 23 angebracht ist und weiterhin auf das Förderband eine pendelnd aufgehängte Rolle 24 drückt, die auf das auszutragende Material entwässernd wirkt. 5, the conveyor belt 2 is in the area of the rising part 6 extended to improve drainage of the material carried out there by reaching in this Area a compression unit 23 is attached and continues to the conveyor belt presses a swinging suspended roller 24 on the material to be discharged has a draining effect.
