Description

Die Erfindung betrifft eine Vorrichtung zum Auswaschen und Sortieren von organischen, lehmartigen und sonstigen Verunreinigungen aus fortlaufend zugeführten grob- und freikörnigen Feststoffen, wie frisch gebaggertem und aufbereitetem Kies, mit einer das Material einer Waschmulde zuführenden Schure und mit Brausen für die Waschflüssigkeit, und weiterhin bestehend aus einem endlosen an Stützrollen und Spannrollen abgestützten Förderhand, die am Maschinengestell derart gehaltert sind, daß ein Teil des Förderbandes stromabwärts der Schurre mit nachfolgender Beruhigungsstrecke angeordnet ist und die Waschmulde bildet sowie der andere Teil des Förderbandes unterhalb der schurre und gegen die Fließrichtung des aufzugebenden Materials ansteigend angeordnet ist, wobei das förderband entgegen der Fließrichtung des über die Schurre aufzugebenden Materials angetrieben ist.The invention relates to a device for washing out and sorting organic, clay-like and other impurities from continuously supplied coarse and free-grained solids, such as freshly dredged and processed gravel, with a shear supplying the material of a washing trough and with showers for the washing liquid, and also existing from an endless conveyor hand supported on support rollers and tensioning rollers, which are held on the machine frame in such a way that part of the conveyor belt is arranged downstream of the chute with a subsequent calming section and forms the washing trough, and the other part of the conveyor belt below the chute and against the direction of flow of the material to be fed is arranged to rise, the conveyor belt being driven counter to the direction of flow of the material to be fed in via the chute.

Eine Vorrichtung mit diesen Merkmalen ist bekannt (DE-PS 2542940). Diese Vorrichtung dient dazu, aus fortlaufend zugeführten körnigen Feststoffen, wie beispielsweise frisch gebaggertem Kies, Fremdstoffe auszuscheiden und zwar mit Hilfe einer Waschflüssigkeit, insbesondere Wasser, in der diese Fremdstoffe sich sammeln und schwimmend ausgetragen werden. Bei diesen Fremdstoffen handelt es sich insbesondere um Holzstücke, Humus, Lehm, Kohle, Faulgestein oder sonstige organische und spezifisch leichtere Bestandteile. Der an die Waschmulde anschließende Teil des Förderbandes dient im wesentlichen als Beruhigungsstrecke, die bewirken soll, daß in hohem Maße Kieskörnung und Sand zurückgehalten wird, d.h. nicht mit den Verunreinigungen ausgeschwemmt wird. Grundsätzlich erfolgt eine Anpassung der Vorrichtung an das zugeführte Gut durch Ändern des Waschbettes und der anschließenden Trennstrecke. Es hat sich gezeigt, daß in der Trennstrecke bereits getrennnte Stoffe sich wieder mischen bzw. die Trennung im Bereich des Waschbettes nicht zufriedenstellend ist, wobei der Wirkungsgrad der Vorrichtung nicht optimal ist. Es ist daher in vielen Fällen notwendig, zur weiteren Verminderung des Schadstoffanteils das Fertigprodukt erneut ein- oder mehrfach einer Aufbereitung zuzuführen.A device with these features is known (DE-PS 2542940). This device serves to separate out foreign substances from continuously supplied granular solids, such as, for example, freshly dredged gravel, with the aid of a washing liquid, in particular water, in which these foreign substances collect and are discharged in a floating manner. These foreign substances are in particular pieces of wood, humus, clay, coal, digester rock or other organic and specifically lighter constituents. The part of the conveyor belt adjoining the washing trough serves essentially as a calming section, which is intended to ensure that gravel and sand are retained to a high degree, ie are not washed out with the contaminants. Basically, the device is adapted to the material supplied by changing the wash bed and the subsequent separation section. It has been shown that substances already separated in the separation zone mix again or the separation in the area of the wash bed is unsatisfactory, the efficiency of the device not being optimal. In many cases it is therefore necessary to reprocess the finished product one or more times to further reduce the pollutant content.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung der eingangs genannten Art den Schadstoffaustrag und damit den Wirkungsgrad zu verbessern.The invention has for its object to improve the pollutant discharge and thus the efficiency in a device of the type mentioned.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß im Bereich der der von dem Förderbande gebildeten Waschmulde wenigstens eine klopfrolle vorgesehen ist, die mit einem oder mehreren quer zur Laufrichtung des Föderbandes angeordneten Stegen versehen ist, die Erhebungen an der Oberfläche der Klopfrolle darstellen.This object is achieved according to the invention in that at least one knocking roller is provided in the area of the washing trough formed by the conveyor belt and is provided with one or more webs arranged transversely to the running direction of the conveyor belt, which elevations represent the surface of the knocking roller.

Eine vorteilhafte Ausführugnsform besteht darin, daß die Klopfrolle am Übergang zwischen der Waschmulde und der Beruhigungsstrecke angeordnet ist.An advantageous embodiment is that the knocking roller is arranged at the transition between the washing trough and the calming section.

Eine weitere vorteilhafte Ausführugnsform sieht vor, daß im Bereich der Waschmulde oberhalb des Förderbandes entgegen seiner Laufrichtung gerichtete Brausen vorgesehen sind.A further advantageous embodiment provides that showers directed against its direction of travel are provided in the area of the washing trough above the conveyor belt.

Weiterhin ist es vorteilhaft, daß die Stütz- bzw. Klopfrollen horizontal und vertikal verstellbar sind.It is also advantageous that the support or knocking rollers are horizontally and vertically adjustable.

Es ist vorteilhaft, daß die Stege z.B. einen runden, halbrunden oder mehrkantigen Querschnitt aufweisen und beispielsweise aus Metall, Gummi oder Kunststoff bestehen.It is advantageous that the webs e.g. have a round, semicircular or polygonal cross-section and consist for example of metal, rubber or plastic.

Es hat sich gezeigt, daß der Schadstoffaustrag durch die Ausbildung der Bett-Unterstützungsrolle als Klopfrolle erheblich verbessert wird. Die Klopfrolle bewirkt ein Pulsieren des Gutes im Bereich der Trennstrecke. Unterstützt wird diese Maßnahme durch die im Bereich der Pulsstrecke oberhalb des Waschbettes angeordneten Brausen, die die durch das trenngerechte Pulsieren aufsteigenden leichten Schadstoffanteile zum Schadstoffaustrag fördern.It has been shown that the discharge of pollutants is considerably improved by the formation of the bed support role as a knocking role. The knocking roller causes the material to pulsate in the area of the separation zone. This measure is supported by the showers arranged in the area of the pulse section above the wash bed, which promote the slight pollutant components that rise due to the separation-appropriate pulsation for pollutant discharge.

Die Erfindung wird in der nachfolgenden Beschreibung anhand von in den Zeichnungen dargestellten Ausführugnsbeispielen näher erläutert.The invention is explained in more detail in the following description with reference to exemplary embodiments shown in the drawings.

Die in den Figuren 1 und 2 dargestellte Vorrichtung besitzt ein Maschinengestell 1, das aus einzelnen Trägern 2, 26 zusammengesetzt ist, die mit einer Innenverkleidung zur Bildung eines Behälters 27 mit einem Abgangstrichter 28 versehen sind. An den einzelnen Trägern 2, 26 sind Druck- bzw. Unterstützungsrollen gehaltert, um die ein Förderband 29 geführt ist. Für den eigentlichen Auswaschvorgang dient der obere Teil des Förderbandes 29, wobei ein abwärts einer Schurre 12 angeordneter Teil 9 des Förderbandes 29 die eigentliche Waschmulde 30 bildet und ein weiterer Teil 11 des Förderbandes 29 unterhalb der Schurre 12 gegen die Fließrichtung des über die Schurre aufgegebenen Materials ansteigend angeordnet ist. Die Form der Waschmulde 30 wird durch die in der Mitte zwischen den äußeren Umlenkrollen 7, 32 am Träger angeordnete höhenverstellbare Druckrolle 18, sowie den verstellbaren Rollen 6, 17 gebildet. Im Bereich des Teiles 9 des Förderbandes 29 ist dieses ganz außen über eine weitere Umlenkrolle 32 geführt, die gleichzeitig als Spannrolle dient, wobei zwischen den Rollen 6 und 32 ein waagerecht bzw. schwach geneigt verlaufender Teil 33 (Beruhigungsstrecke) des Förderbandes 29 vorgesehen ist. Der entgegengesetzte Teil 11 des Förderbandes 29 ist am obersten Punkt über eine Antriebsrolle 7 mit Antriebsmotor 34 geführt, wobei die Rolle 7 mit Unterlegplatten 35 höhenverstellbar ist. Unterhalb der Druckrolle 18 ist das Förderband über eine Umlenkrolle 31 geführt. Die Rolle 31 ist am Träger 2 höhenverstellbar angeordnet, während die Rollen 6 und 17 sowohl vertikal als auch horizontal verstellbar sind.The device shown in FIGS. 1 and 2 has a machine frame 1 which consists of individual carriers 2, 26 is composed, which are provided with an inner lining to form a container 27 with an outlet funnel 28. On the individual carriers 2, 26, pressure or support rollers are held, around which a conveyor belt 29 is guided. The upper part of the conveyor belt 29 is used for the actual washing-out process, a part 9 of the conveyor belt 29 arranged downstream of a chute 12 forming the actual washing trough 30 and a further part 11 of the conveyor belt 29 below the chute 12 against the flow direction of the material fed in via the chute is arranged increasing. The shape of the washing trough 30 is formed by the height-adjustable pressure roller 18 arranged in the middle between the outer deflection rollers 7, 32 on the carrier, and the adjustable rollers 6, 17. In the area of part 9 of the conveyor belt 29, this is guided on the very outside via a further deflection roller 32, which also serves as a tensioning roller, a horizontally or slightly inclined part 33 (calming section) of the conveyor belt 29 being provided between the rollers 6 and 32. The opposite part 11 of the conveyor belt 29 is guided at the uppermost point via a drive roller 7 with a drive motor 34, the roller 7 being adjustable in height with washers 35. Below the pressure roller 18, the conveyor belt is guided over a deflection roller 31. The roller 31 is arranged on the support 2 so as to be adjustable in height, while the rollers 6 and 17 are adjustable both vertically and horizontally.

Die Unterstützungsrolle 6 ist als Klopfrolle ausgebildet, d.h. an ihrem Umfang befindet sich wenigstens eine Erhebung, die quer zum Förderband 29 ausgerichtet ist. Als Erhebung oder Klopfleisten können beispielsweise Rundeisen vorgesehen sein, wobei die Anzahl der Stege von dem zu bearbeitenden Gut, der Bandgeschwindigkeit und dem Trommeldurchmesser der Umlenkrolle 6 abhängig ist. Als Pulsstrecke 14 ist im wesentlichen die Strecke zwischen der mittleren Druckrolle 18 und der Klopfrolle 6 anzusehen. In diesem Bereich können ggfs. weitere Klopfrollen angeordnet werden. Insbesondere sind in diesem Bereich oberhalb der Waschmulde einzelne Brausen 8 angeordnet, die entgegen der Laufrichtung 4 des Förderbandes 29 ausgerichtet sind. Im Bereich des ansteigenden Teiles 11 des Förderbandes 29 befinden sich Hilfsbrausen 10, die ebenfalls entgegen der Laufrichtung 4 des Förderbandes 29 ausgerichtet sindThe support roller 6 is designed as a knocking roller, ie there is at least one elevation on its circumference, which is oriented transversely to the conveyor belt 29. As Elevation or tapping bars can be provided, for example, round bars, the number of webs depending on the material to be processed, the belt speed and the drum diameter of the deflection roller 6. The distance between the middle pressure roller 18 and the knock roller 6 can essentially be regarded as the pulse path 14. If necessary, further knocking rollers can be arranged in this area. In particular, individual showers 8 are arranged in this area above the washing trough and are oriented counter to the running direction 4 of the conveyor belt 29. In the area of the rising part 11 of the conveyor belt 29 there are auxiliary showers 10, which are also aligned counter to the running direction 4 of the conveyor belt 29

Bei einer derartigen Vorrichtung, bei der die Waschmulde 30 ohne Verwendung der Druckrolle 18 gebildet wird, können die Klopfrolle (n) 6 im gesamten Bereich der Waschmulde 30 angeordnet sein.In such a device, in which the washing trough 30 is formed without using the pressure roller 18, the tapping roller (s) 6 can be arranged in the entire region of the washing trough 30.

Bei der Ausführungsform nach den Figuren 1 und 2 befindet sich das Förderband 29 zwischen Seitenwänden 36 des Materialauffangbehälters 27, während bei der weiteren Ausführungsform nach Fig. 3 das Förderband 29 als Wellkantengurt ausgebildet ist und hochstehende Seitenteile 5 aufweist.In the embodiment according to FIGS. 1 and 2, the conveyor belt 29 is located between side walls 36 of the material collecting container 27, while in the further embodiment according to FIG. 3 the conveyor belt 29 is designed as a corrugated edge belt and has upstanding side parts 5.
