AbsiebeinrichtungScreening device

Bisherige Absiebeinrichtungen für nasses Kunststoff - Mahlgut oder Granulat ueruenden hauptsächlich Rüttelsiebe, die außer einem großen Platzbedarf sehr geräuschvoll sind, zur Schuingungsbeherrschung und Antrieb eine aufuendige Technik mit entsprechender Wartung benötigen und deshalb teuer sind.Previous screening devices for wet plastic grinding material or granulate mainly consist of vibrating screens, which, in addition to requiring a lot of space, are very noisy, require complex technology for vibration control and drive with corresponding maintenance, and are therefore expensive.

Die Erfindung bezieht sich auf eine Absiebeinrichtung ohne diese Nachteile. The invention relates to a screening device without these disadvantages.

Die bisher lineare Absiebung uird durch eine einseitig offene langsam rotierende Siebtrommel ersetzt, die das Uasser - Kunststoffgemisch unten aufnimmt, das Wasser im v/erlaufe der Drehung absiebt und den abgesiebten Kunststoff oben abgiebt.The previous linear screening is replaced by a slowly rotating screening drum that is open on one side and takes in the water-plastic mixture at the bottom, screens the water as it rotates and discharges the screened plastic at the top.

Weitere Einzelheiten der Erfindung sind dem in den Zeichnungen dargestellten Ausführungsbeispiel zu entnehmen:Further details of the invention can be found in the embodiment shown in the drawings:

Fig. 1 Seitenansicht auf Trenntrommel und Fördergebläse Fig. 2 Trenntrommel im Schnitt.Fig. 1 Side view of separating drum and conveyor fan Fig. 2 Separating drum in section.

Die einseitig offene, v/om drehzahlregelbaren Antrieb (1) angetriebene Siebtrommel (2) ist als Zellenrad (3) ausgebildet und außen mit einem Siebgewebe (4) bespannt. Das abzusiebende Wasser - Kunststoffgemisch wird in Richtung des Pfeiles (5) der ablaufenden Seite der Siebtrommel (2) zugeführt.Im Wasserbehälter (6) wird das abgesiebte Wasser gesammelt und über die Rückförderpumpe (7) der neuerlichen Verwendung zugeführt.The screen drum (2), which is open on one side and driven by the speed-adjustable drive (1), is designed as a cellular wheel (3) and is covered on the outside with a screen fabric (4). The water-plastic mixture to be screened is fed to the draining side of the screen drum (2) in the direction of the arrow (5). The screened water is collected in the water tank (6) and fed for reuse via the return pump (7).

Der in den Maschen des Siebgeuebes (4), durch die Oberflächenspannung hängenbleibende Uasserfilm wird dem Siebgewebe (4) durch das an den Halterungen (8/9) befestigte, und an der Siebtrommel (4) anliegende Schuammtuch (10) entzogen und tropft ebenfalls in den Wasserbehälter (6) ab.The water film that remains in the mesh of the sieve fabric (4) due to the surface tension is removed from the sieve fabric (4) by the foam cloth (10) attached to the brackets (8/9) and resting on the sieve drum (4) and also drips into the water container (6).

Der in den Zellen (3) der Siebtrommel (2) verbliebene Kunststoff fällt, v/om Abblasgebläse (11) unterstützt, in den am Fördergebläse (12) befestigten Auffangtrichter (13) und uird vom Fördergebläse (12) der weiteren Verarbeitung zugeführt.The plastic remaining in the cells (3) of the screening drum (2) falls, assisted by the blower (11), into the collecting funnel (13) attached to the conveyor fan (12) and is fed by the conveyor fan (12) for further processing.
