Description
Die Erfindung betrifft eine Vorrichtung zum Auswaschen und Sortieren von organischen, lehmartigen und sonstigen Verunreinigungen aus fortlaufend zugeführten grob- und feinkörnigen Feststoffen, wie frisch gebaggertem und aufbereitetem Kies, mit einer das Material einer Waschmulde zuführenden Schurre und Brausen für die Waschflüssigkeit, bestehend aus einem endlosen an Stützrollen und Spannrollen abgestützten Förderband, die am Maschinengestell derartgehaltert sind, daß ein Teil des Förderbandes stromabwärts der Schurre mit nachfolgender Beruhigungsstrecke angeordnet und als Waschmulde vorgesehen ist sowie der andere Teil des Förderbandes unterhalb der Schurre und gegen die Fließrichtung des aufgegebenen Materials ansteigend angeordnet ist, wobei das Förderband entgegen der Fließrichtung des über die Schurre aufgebenen 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 fine-grained solids, such as freshly dredged and processed gravel, with a chute and shower for the washing liquid, which material supplies a washing trough, consisting of an endless Conveyor belt 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 is provided as a washing trough, and the other part of the conveyor belt is arranged below the chute and rising upward against the direction of flow of the material fed in, the conveyor belt being driven counter to the direction of flow of the material applied via the chute.
Eine Vorrichtung mit diesen Merkmalen ist bekannt (DE-PS 25 42 940). 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 Bestand teile. Der an die Waschmulde anschließende Tal 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 25 42 940). 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, rotten rock or other organic and specifically lighter stocks parts. The valley 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 Waschmulde des Förderbandes wenigstens eine Klopfrolle vorgesehen ist, die mit einem oder mehreren quer zur Laufrichtung des Förderbandes angeordneten Stegen versehen ist, die Erhebungen an der Oberfläche der Klopfrolle darstellen.This object is achieved according to the invention in that in the area of the washing trough of the conveyor belt at least one knocking roller is provided, which is provided with one or more webs arranged transversely to the running direction of the conveyor belt, which represent elevations on 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.
