Abstract
Description
Die Erfindung betrifft ein Vibrations-Sieb zur Separierung von unförmigen Granulaten, Strangstäbchen, Granulat-Zusammen backungen etc., von gewünschtem Granulat.The invention relates to a vibrating screen for separation of misshapen granules, rod sticks, granules together baking etc. of the desired granulate.
Das Granulat wird dabei dosiert in die Mitte des vibrierenden Siebes aufgegeben.The granulate is dosed in the middle of the vibrating Siebes abandoned.
Durch die gewölbte Form des Siebbleches rutschen die Granulat teile, die größer als die Löcher des Siebes sind seitwärts bis zur Siebbegrenzung, wo ein schmaler nicht gelochter, gegen über dem Sieb abgesetzter Streifen die fehlerhaften Granulat teile aufnimmt und durch die Vibration zum Auslauf des Siebes transportiert.The granulate slides through the curved shape of the sieve plate parts larger than the holes of the sieve are sideways up to limit the sieve, where a narrow not perforated, against the defective granules above the sieve absorbs parts and vibrates to the outlet of the sieve transported.
Derartige Siebe mit gewölbten Böden sind bekannt. Es ist ebenfalls bekannt, daß derartige Siebe entlang des Rahmens einen nicht gelochten Bereich haben.Such screens with curved bottoms are known. It is also known that such screens along the Frame has a non-perforated area.
Bei diesen Ausführungsformen besteht jedoch die Gefahr, daß Granulatteile, die sich bereits im nicht gelochten Bereich des Siebrahmens befinden, durch die Vibration wieder zur Siebmitte geschleudert werden und beim Aufprall in senkrechter Stellung, trotz Überlänge durch die Sieblochung fallen.In these embodiments, however, there is a risk that Granulate parts that are already in the non-perforated area of the Due to the vibration back to the middle of the sieve be thrown and in the vertical position on impact, fall through the perforated screen despite being too long.
Der Erfindung liegt daher die Aufgabe zugrunde, das eingangs erwähnte Vibrations-Sieb so zu gestalten, daß ein Rückspringen fehlerhafter Granulate verhindert wird.The invention is therefore based on the object at the outset mentioned vibrating sieve so that it springs back faulty granules is prevented.
Erfindungsgemäß geschieht dies dadurch, daß der nicht gelochte Rand des Siebes als Rinne ausgebildet wird und eine Breite von ca. 3,0 cm aufweist.According to the invention, this is done in that the non-perforated Edge of the sieve is designed as a gutter and a width of approx. 3.0 cm.
Der Absatz an der Grenze zwischen gelochtem und nicht ge lochtem Sieb weist eine Höhe von 0,3-2 cm auf. Ist der Absatz höher wird die Vibration durch die entstehende Versteifung behindert.Sales on the border between punched and not ge perforated sieve has a height of 0.3-2 cm. Is the paragraph The vibration increases due to the resulting stiffening with special needs.
Bei einer Absatzhöhe von weniger als 0,3 cm besteht die Gefahr, daß Granulatteile wieder in den gelochten Bereich zurück geschleudert werden.With a heel height of less than 0.3 cm there is a risk of that granulate parts back into the perforated area to be hurled.
Die Erfindung wird anhand eines Ausführungsbeispiels erläutert. Es zeigtThe invention is explained using an exemplary embodiment. It shows
Fig. 1 den Querschnitt des Siebes, Fig. 1 shows the cross-section of the screen,
Fig. 2 die Draufsicht des Siebes. Fig. 2 is a top view of the sieve.
Das in den Fig. 1 und 2 dargestellte Sieb weist einen nach oben gewölbten, gelochten Siebteil 1 auf, an den sich seitlich ein ca. 3,0 cm breiter nicht gelochter Siebstreifen 3 anschließt. An der Grenze zwischen gelochtem Siebteil 1 und nicht geloch tem Siebstreifen 3 befindet sich ein 0,3-2 cm hoher Absatz 2. Der nicht gelochte Siebstreifen 3 wird an seinem Ende von einer elastischen Dichtung 4, die vorzugsweise aus Gummi besteht, umschlossen.The sieve shown in FIGS. 1 and 2 has an upwardly arched, perforated sieve part 1 , which is adjoined laterally by an approximately 3.0 cm wide, non-perforated sieve strip 3 . At the border between perforated sieve part 1 and perforated sieve strip 3 there is a 0.3-2 cm high heel 2 . The non-perforated sieve strip 3 is enclosed at its end by an elastic seal 4 , which is preferably made of rubber.
Der obere Siebrahmen 5 und der untere Siebrahmen 6 umschließen die Dichtung 4 und halten so das Sieb elastisch in seiner Lage.The upper sieve frame 5 and the lower sieve frame 6 enclose the seal 4 and thus hold the sieve elastically in its position.
