Description

Siebvorrichtung für platten- und stabförmige Teile enthaltendes Schüttgut Die Erfindung betrifft eine Siebvorrichtung für platten- und stabfiörmige Teile enthaltendes Schüttgut. Sie beruht auf der Beobachtung, daß bei Walzenrosten aller Art, also sowohl mit glatten Walzen als auch Scheibenwalzen, in dem Schüttgut enthaltene platten- oder stabfiärmige Teile am Anfang des Walzenrostes nicht. hindurchfallen, solange die Schichthöhe über dem Rosteine genügende Stärke hat, jedoch nach dem Ende des Rostes hin, wo die Schichthöhe geringer wird, durch den Rost hindurchfallen und mit in. das erbgesiebte Feine gelangen. Durch die Einrichtung nach der Erfindung soll dieser Übelstand vermieden werden. Das Neue besteht darin, daß dem Walzenrost als dem ersten Teil. der Siebfläche ein Schwingsieb mit Bespannung aus Drahtgeflecht oder gelochtem Blech von im wesentlichen gleicher Durchgangsweite wie der Rost als zweiter Teil der gemeinsamen Siebfläche unmittelbar nachgeschaltet ist.Sieving device for bulk goods containing plate and rod-shaped parts The invention relates to a screening device for plate-shaped and rod-shaped parts containing bulk material. It is based on the observation that with roller grids everything Art, i.e. both with smooth rollers and disc rollers, contained in the bulk material Plate or rod-shaped parts at the beginning of the roller grate are not. fall through as long as the layer height above the grate is sufficiently thick, but after Fall through the grate towards the end of the grate, where the layer height is lower and get into. the pea-sifted fine. By the device according to the invention this disadvantage should be avoided. The new thing is that the roller grate as the first part. the screen surface is a vibrating screen covered with wire mesh or perforated sheet metal with essentially the same passage width as the grate as second part of the common screen surface is connected immediately downstream.

Es ist bereits bekannt; bei einem Schwingsieb .den ersten Teil der Siebfläche durch umlaufende Walzen zu ersetzen, die in dem Rahmen des Schwingsiebes gelagert sind und mit dem Sieb mitschwingen. Diese Walzen sollen dazu dienen, ein Anhäufen des, Siebgutes an der Aufgabestelle zu verhindern. Die eigentliche Absiebung des Schüttgutes soll bei dieser 'bekannten Bauart jedoch auf der anschließenden Rostfläche vor sich gehen..It is already known; in the case of a vibrating screen. the first part of the Replace the screen surface with rotating rollers in the frame of the vibrating screen are stored and vibrate with the sieve. These rollers are meant to serve a To prevent the material to be sieved from piling up at the feed point. The actual screening of the bulk material should in this' known design, however, on the subsequent Grate surface go in front of you ..

'Ferner ist eine Sieb- und Zerkleinerungsvorrichtung bekannt, die aus einem Walzenrost, von dem der Überlauf in eine Zerkleinerungsvorrichtung gelangt, und einem darunter angeordnetem Schwingsieb besteht. Mit dieser Siebvorrichfung soll also lediglich das Grobe zerkleinert- und zusammen mit dem Walzendurchgang auf dem Schwingsieb- ab.-gesiebt werden. Auf der Zeichnung ist die Einrichtung nach der Erfindung im senkrechten Längsschnitt schematisch dargestellt. Der erste Teil der Siebfläche wird durch den ortsfest gelagerten Walzenrost heliebiger Bauart, z. B. einen Scheibenwalzenrost, gebildet. Der zweite Teil der Siebfläche besteht aus dem Schwingsieb z, das mit einer Siebbespannung oder gelochten Blechen von im wesentlichen gleicher Durchgangsweite wie der Rost versehen ist. Die ganze Einrichtung ist in dem Rumpf 3 angeordnet, der unter dem Ende der Siebvorrichtung mit der Ablaufschurre q. für das grobe Gut versehen ist. Die Aufgabe des Siebgutes erfolgt durch die Aufgabeschurre 5.'Furthermore, a sieving and comminuting device is known which from a roller grate, from which the overflow reaches a shredding device, and a vibrating screen arranged below. With this Siebvorrichfung so only the coarse is to be crushed and together with the roller passage be sieved on the vibrating sieve. The device is shown on the drawing the invention shown schematically in vertical longitudinal section. The first part the screen surface is covered by the stationary roller grate of any type, z. B. a disc roller grate formed. The second part consists of the sieve surface from the vibrating sieve z, which is covered with a sieve or perforated sheet metal from im essentially the same passage width as the grate is provided. The whole facility is arranged in the body 3, which is below the end of the screening device with the discharge chute q. is provided for the coarse goods. The material to be screened is fed through the feed chute 5.

Das Siebgut läuft zunächst über den Walzenrost i. Der Überlauf dieses Teiles der Siebhäehe gelangt dann auf das Schwingsieb z. Der Überlauf des Schwingsiebes wird durch die Schurre q. abgeführt, während das durchfallende Feine in den Rumpf 3 ,gelangt.The screenings first run over the roller grate i. The overflow of this Part of the Siebhähe then reaches the vibrating screen z. The overflow of the vibrating screen is through the chute q. dissipated while the falling fine into the trunk 3, arrives.

Durch die Einrichtung mach der Erfindung wird eine gute Trennung von platten- oder stabfiörmigen Teilen aus dem Siebgut: erreicht und vermieden, daß derartige Teile im. das erbgesiebte Feingut gelangen.By establishing the invention, there is a good separation of Plate or rod-shaped parts from the screenings: achieved and avoided that such parts in. the sieved fine material arrive.
