Description

Vorrichtung zum Sichten von Massengut Die Erfindung betrifft - eine Vorrichtung zum Sichten* von Massengut mittels durch ein das Gut tragendes Sieb oder Band geleiteter Luft oder Gases, und das Neue besteht darin, daß die Zuleitung des Gases oder der Luft durch bewegliche Düsen erfolgt. Vorteilhaft ist es dabei, wenn die Düsen geneigt, zweckmäßig gegeneinander geneigt, angeordnet sind. Durch die Erfindung ergibt sich eine Ersparnis an Düsen und damit an Druckluft. Es brauchen nämlich nicht mehr so viel Düsen vorgesehen zu werden, daß jeder Teil der Sieb- oder Bandbreite von einem Luftstrahl bestrichen wird, sondern es genüge weniger, unter Umständen sogar eine einzige Düse, die beim Hinundherbewegen über das Band oder Sieb quer zu ihm dessen ganze Breite zu bestreichen vermag. @ Infolge der Neigung der Düsen wird dabei durch die mit der Neigung hervorgerufene schräge Strahlrichtung eine Förderung des Gutes bewirkt, und zwar eine Förderung in anderer Richtung, als sie das Band oder Sieb bewirkt; die Neigung mehrerer Düsen gegeneinander ruft dabei solche Förderungen in verschiedenen Richtungen hervor, was ein Umrühren des auf dem Band oder Sieb befindlichen Gutes verursacht. Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung schematisch dar.Apparatus for sifting bulk goods The invention relates to a Device for sifting * bulk goods by means of a sieve carrying the goods or band of conducted air or gas, and the novelty is that the supply line of the gas or air takes place through movable nozzles. It is advantageous to when the nozzles are inclined, appropriately inclined to one another, are arranged. By the invention results in a saving of nozzles and thus of compressed air. Need it namely not to be provided so many nozzles that each part of the sieve or bandwidth is swept by an air jet, but it is less sufficient possibly even a single nozzle to be used when moving back and forth across the belt or sieve across its entire width. @ As a result of the inclination of the nozzle is caused by the inclined jet direction caused by the inclination a promotion of the good causes, and a promotion in a different direction than it effects the belt or sieve; the inclination of several nozzles against each other calls out such promotions emerge in different directions, causing a stir on the material located on the belt or sieve. The drawing represents an embodiment of the invention schematically.

Der Boden des Sichtkastens I ist als Sieb in Form eines in der Richtung des Pfeiles x umlaufenden endlosen Bandes 2 ausgebildet. Das Gut wird durch den Zulauf 3 aufgegeben und läuft durch die Ableitung.I hinaus. Von dem Gebläse 5 wird durch die Leitung 6 Druckluft oder Druckgas geliefert. Die Leitung 6 trägt bewegliche, gegeneinander geneigte Düsen 7, die mittels des Antriebes 8 hin und her geschwenkt werden. Die durch die Düsen 7 in den über dem Siebband 2 befindlichen Sichtkasten i eingeblasene Luft oder das Gas zieht durch die Ableitung g aus diesem ab.The bottom of the viewing box I is as a sieve in the form of one in the direction of the arrow x revolving endless belt 2 is formed. The good is made by the Inlet 3 abandoned and runs out through outlet I. From the fan 5 is supplied through line 6 compressed air or pressurized gas. The line 6 carries movable, nozzles 7 inclined to one another and pivoted back and forth by means of the drive 8 will. The through the nozzles 7 in the viewing box located above the screen belt 2 i injected air or the gas is withdrawn from it through the outlet g.
