Description

Die Erfindung .bezieht sich auf ein Verfahren zum Sieben von schmierendem Gut auf Schwingsieben. Erfahrungsgemäß neigt schmierendes Gut dazu, beim Sieben die Sieböffnungen, die kleiner als etwa i5 mm sind, allä#ähli.ch'z-üzusetzen. ITiii". das gewünschte Siebergebnis zu erreichen, müssen entweder die Sieböffnungen von Zeit zu Zeitgesäubert oder besondere Vorrichtungen zum Offenhalten der Sieböffnungen vorgesehen werden.The invention relates to a method for sieving lubricant Good on vibrating screens. Experience has shown that lubricating material tends to do so when sieving the sieve openings, which are smaller than about 15 mm, must allä # ähli.ch'z-ü put. ITiii ". To achieve the desired sieving result, either the sieve openings of Time to time cleaned or special devices to keep the sieve openings open are provided.

Die Erfindung gibt nun einen Weg an, durch den in einfacher Weise ein Zusetzen der Sieböffnungen unterbunden wird. Erreicht wird dies dadurch, daß gleichzeitig mit dem Siebgut abriebfestes Gut im ständigen Kreislauf auf die Siebfläche aufgegeben wird, dessen Korngröße oberhalb 'derjenigen- des zu -siebenden Gutes liegt. Dieses an der Siebung nicht' teilnehmende, jedoch während seiner Wanderung über die Siebfläche mitschwingerlcle Gut Übernimmt beim Siebvorgang die Rolle von Hämmern; -die dauernd auf die Siebfläche einwirken und dadurch ein Zusetzen .der Sieböffnungen durch Bestandteile -des schmierenden Siebgutes verhindern.The invention now provides a way by which in a simple manner clogging of the sieve openings is prevented. This is achieved in that At the same time as the material to be screened, abrasion-resistant material is constantly circulating on the screen surface is abandoned, the grain size of which is greater than that of the goods to be screened lies. This one not 'participating in the screening, but during its migration Schwingerlcle Gut takes over the role of during the sieving process Hammer; -that have a permanent effect on the sieve surface and thereby clogging Prevent sieve openings through components of the lubricating material to be sieved.

In der Zeichnung ist ein Sieb zur Ausübung des Verfahrens gemäß der Erfindung schematisch dargestellt..In the drawing is a sieve for performing the method according to Invention shown schematically ..

Ein ur Kreis-, Ellipsen- oder geradlinigen Schwingungen erregtes - Sieb, das beispielsweise dazu dienen soll, schmierendes Siebgut in der Korngröße von o bis 2o mm in die Körnungen o bis. io und io bis 2o mm zu trennen, ist mit den entsprechenden Siebbelägen i und 2 versehen. Unterhalb der Siebbeläge sind die Auf fangtrichter3 und q. angeordnet. Das Siebgut wird an dem einen, im Falle des Ausführungsbeispieles oberen Ende der Siebfläche aufgegeben. Gleichzeitig wird abriebfestes Gut in der Korngröße über 30 mm dein oberen .Ende der Siebfläche zugeführt.- Beide Gutsorten -wandern gemeinsam über die Siebfläche. Sich in den Sieböffnungen etwa festsetzende Bestandteile des schmierenden Gutes werden durch,die auf die Siebfläche.-dauernd ausgeübten Schläge der zusätzlichen groben Gutteile laufend gelockert und zum Durchfallen gezwungen. -Am unteren Ende der Siebfläche ist ein Auffangtrichter 5 für»die-zusätzlichen Gutteile vorgesehen, aus dem diese fortlaufend vorzugsweise auf mechanischem Wege entnommen und dem oberen Ende der Siebfläche wieder -zügeführt werden.A very circular, elliptical or straight-line vibrations - sieve, which should serve, for example, lubricating sieve material in the grain size of o to 20 mm in the grains of o to. To separate io and io up to 2o mm is provided with the corresponding screen linings i and 2. The collecting funnels3 and q are below the screen linings. arranged. The material to be screened is placed at one end of the screen surface, which in the case of the exemplary embodiment is the upper end. At the same time, abrasion-resistant material with a grain size of over 30 mm is fed to the upper end of the sieve surface. Both types of material migrate together over the sieve surface. Any constituents of the lubricating material that get stuck in the sieve openings are continuously loosened and forced to fall through by the blows of the additional coarse material that are constantly being exerted on the sieve surface. At the lower end of the sieve surface there is a collecting funnel 5 for the additional good parts, from which these are continuously removed, preferably by mechanical means, and fed back to the upper end of the sieve surface.

- Das beschriebene Verfahren kann selbstverständlich auch bei Sieben mit zwei oder mehr übereinanderliegenden Siebflächen zur Anwendung kommen.- The procedure described can of course also be used for seven with two or more superimposed sieve surfaces are used.
