Description
Die Erfindung betrifft eine Vorrichtung zur Behandlung von körnigem Material, insbesondere Sand, mit einem Behälter, der einen Überlauf, einen Sinkgutauslaß und eine Frischwasserzuführung besitzt, wobei im oder am Behälter zumindest ein Schwingungserzeuger angeordnet ist, mittels dessen die im Behälter befindliche Wassersäule in Schwingung versetzbar ist.The Invention relates to a device for treating granular material, especially sand, with a container, the one overflow, a Sinkgutauslaß and a fresh water supply possesses, in or on the container at least one vibration generator is arranged, by means of which the in the container located water column is vibratable.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Behandlung von körnigem Material, insbesondere Sand, zu schaffen, der bei verringertem Frischwasserbedarf zu einer hohen Trenngenauigkeit führt.Of the Invention is based on the object, a device for treatment of grainy Material, especially sand, to create, with reduced fresh water needs leads to a high separation accuracy.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.These The object is achieved by the Characteristics of claim 1 solved.
Es hat sich gezeigt, dass durch die gleichzeitige Einbringung unterschiedlicher Schwingungen in die Wassersäule sich eine verbesserte Beweglichkeit der abzuscheidenden Verunreinigungen oder Teilchen auch bei höheren Schwertrübekonzentrationen über 1,4 kg/dm3 Trübegewicht einstellt, wodurch die Trenngenauigkeit wesentlich erhöht ist, da die Teilchen einen stärkeren Auftrieb erfahren. Dies führt dazu, dass die zuzuführende Frischwassermenge, mit der die Teilchen über den Überlauf ausgeschwemmt werden sollen, entsprechend verringert werden.It has been shown that the simultaneous introduction of different vibrations in the water column, an improved mobility of the deposited impurities or particles sets at higher Schwertrübekonzentrationen over 1.4 kg / dm 3 turbid weight, whereby the separation accuracy is substantially increased because the particles experienced a stronger boost. This means that the amount of fresh water to be supplied, with which the particles are to be flushed out via the overflow, be reduced accordingly.
Es hat sich gezeigt, dass die Trenngenauigkeit zwischen dem Basismaterial, d. h. dem Sand, und den Verunreinigungen je nach Art des Basismaterials und der Verunreinigungen sich durch Wahl eines geeigneten Schwingungsmusters, d. h. einer Überlagerung vorbestimmter, unterschiedlich gerichteter Schwingungen, verbessern lässt. Die für die jeweiligen zu behandelnden Materialien bestmöglichen Schwingungsmuster lassen sich experimentell ermitteln und werden dann vorzugsweise in einer Steuereinheit abgespeichert, aus der sie von einem Bediener in Abhängigkeit von dem zu behandelnden Material abgerufen werden können. Wenn der Bediener beispielsweise feststellt, dass er relativ feinkörnigen Sand mit Verunreinigungen in Form von größeren Holzstückchen behandeln soll, stellt er an der Steuereinheit das entsprechende Schwingungsmuster ein, wodurch die Schwingungserreger in vorbestimmter Weise angesteuert werden, so dass sie unterschiedliche Einzelschwingungen erzeugen, die in Überlagerung eine für das zu behandelnde Material vorteilhafte Gesamtschwingung ergeben.It it has been shown that the separation accuracy between the base material, d. H. the sand, and the impurities depending on the nature of the base material and impurities by choosing an appropriate vibration pattern, d. H. an overlay predetermined, differently directed vibrations improve leaves. The for let the respective materials to be treated best possible vibration pattern determine themselves experimentally and are then preferably in one Control unit stored from which they are dependent on an operator can be retrieved from the material to be treated. If For example, the operator finds that he has relatively fine-grained sand treat with impurities in the form of larger pieces of wood If necessary, he sets the appropriate vibration pattern on the control unit a, whereby the vibration exciter driven in a predetermined manner so that they produce different individual vibrations, in overlay one for give the material to be treated advantageous overall vibration.
Es wird also vorgeschlagen, das untere Behälterteil in seiner Gesamtheit durch einen flexiblen Schlauch auszubilden.It Thus, it is proposed that the lower container part in its entirety form by a flexible hose.
Der Schlauch kann einen kreisförmigen, ovalen oder polygonförmigen Querschnitt aufweisen und ist vorzugsweise in zumindest eine Ebene gekrümmt. Durch die Krümmung des elastischen Schlauches entstehen unterschiedliche Vektorenwinkel innerhalb des sich im Schlauch bildenden Materialstroms bereits dann, wenn der Schlauch nur durch einen Schwingungserreger in lineare Schwingungen versetzt wird. Auf diese Weise ist der vorrichtungstechnische Aufwand gering gehalten und allein durch die Formgebung des Schlauches lassen sich unterschiedlich gerichtete Schwingungen mittels nur eines einzigen Schwingungserregers erzielen. Alternativ können jedoch auch mehrere Schwingungserreger vorgesehen sein, die am oberen Behälterteil und/oder am unteren Behälterteil angreifen können.The tube may have a circular, oval or polygonal cross-section and is preferably curved in at least one plane. Due to the curvature of the elastic tube different vectors angle within the forming material in the tube material flow already arise when the hose ver only by a vibration exciter in linear vibrations is set. In this way, the device complexity is kept low and only by the shape of the tube can be achieved differently directed vibrations by means of only a single vibration exciter. Alternatively, however, it is also possible to provide a plurality of vibration exciters which can act on the upper container part and / or on the lower container part.
Die Vorrichtung weist vorzugsweise eine Steuervorrichtung zur Ansteuerung der Schwingungserreger auf, wobei in einer Speichereinheit der Steuervorrichtung verschiedene Schwingungsmuster gespeichert sind, die in Abhängigkeit von dem zu behandelnden Material abrufbar sind, um in oben dargestellter Weise eine optimale, überlagerte Gesamtschwingung der Wassersäule zu erreichen.The Device preferably has a control device for driving the vibration exciter, wherein in a memory unit of the control device different vibration patterns are stored, depending on are retrievable from the material to be treated to in the above Way an optimal, superimposed Total vibration of the water column to reach.
In Weiterbildung der Erfindung kann vorgesehen sein, dass der Querschnitt des unteren Behälterteils, d. h. des Schlauches, von seinem oberen Ende zu seinem unteren Ende hin in Stufen oder kontinuierlich abnimmt, wodurch Materialbewegungen ermöglicht werden, die die Abscheidung und Sortierung unterstützen.In Further development of the invention can be provided that the cross section the lower container part, d. H. of the hose, from its upper end to its lower end down in steps or continuously, allowing material movements which support the separation and sorting.
