Description

Beschreibung der Erfindung (Aktenz. P 19 54 611. 3) Titel: Klassiervorrichtung Anwendungsgebiet:Die Vbrrichtung dient dazu, Mischungen von Stoffen mit unterschiedlicher Korngröße (z. B. Sande) und/oder unterschiedlicher Wichte (z. B. Mineralien) zu klassieren.Description of the invention (file no. P 19 54 611. 3) Title: Classifying device Area of application: The Vbrrichtung serves to mix of substances with different Grain size (e.g. sand) and / or different density (e.g. minerals) classify.

Stand der Technik: Bei den üblichen Verfahren wird die unterschiedliche Sinkgeschwindigkeit der Bestandteile des zu klassierenden Stoffes durch ein, dem absinkenden Stoff mit einer konstanten oder sich ändernder Geschwindigkeit, entgegenströmendes Medium (Ze B.State of the art: With the usual methods, the different Sink rate of the constituents of the substance to be classified by one, the Sinking matter at a constant or changing speed, countercurrent Medium (Ze B.

Gas oder Flüssigkeit) zur Trennung der Bestandteile ausgenützt.Gas or liquid) to separate the components.

Diese Verfahren bedingen eine aufwendige Apparatur Auigabe:Der Erfindung liegt die Aufgabe zugrunde, die Größe und/ oder anzahl der Aggregate einer Anlage zu verringern und dadurch das Verfahren zu rationalisieren.These processes require complex equipment. Assignment: The invention the task is based on the size and / or number of units in a system and thereby streamline the process.

Lösung: Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Überlagerung von freiem Fall der Teilchen und horizontaler Bewegung des Transportmediums (mit variabler Geschwindigkeit) zur Klassierung ausgenützt werden.Solution: This object is achieved according to the invention in that the Superposition of free fall of the particles and horizontal movement of the transport medium (with variable speed) can be used for classification.

tusiUhrungsbeispiel: In Wasser aufgeschlSmmter Sand soll klassiert werden. Die Aufschlämmung wird an der Schmalseite eines Behälters zugeführt. Der Behälter erweitert sich in Strömungsrichtung, ebenso fällt sein Boden in dieser Richtung ab (Verminderung der horizontalen Geschwindigkeit). Bm Boden wird abschnittweise (Segmente iolgen in Strömungsrichtung aufeinander) abgesaugt. Die groben Teilchen (höhere Vertikalgeschwindigkeit) fallen in den der Eintrittsseite an nächsten liegenden absaugkanal an; die feinsten Teilchen am entgegengesetzten Ende.Practical example: sand suspended in water should be classified will. The slurry is fed in on the narrow side of a container. Of the The container expands in the direction of flow, and its bottom also falls in this direction Direction down (reduction of the horizontal speed). Bm floor will be in sections (Segments follow one another in the direction of flow). The coarse particles (higher vertical speed) fall into the one closest to the entry side suction channel on; the finest particles on the opposite end.
