Einrichtung zum Trennen / Sortieren von rieselfä'hiqen Feststoffen insbesondere von gemahlenen Kunststoff -Abfällen. Device for separating/sorting free-flowing solids, particularly ground plastic waste.

Die Erfindung bezieht sich auf eine Einrichtung zur nahezu sortenreinen trockenen Trennung / Sortierung von rieselfähigen Feststoffen mit unterschiedlichen Erueichungs / Schmelzpunkten uie z.B. zerkleinerte / gemahlene Kunststoffabfälle, Altverpackungen, Kunststoffmüll, Kabelabfälle.The invention relates to a device for the almost pure dry separation/sorting of free-flowing solids with different softening/melting points, such as shredded/ground plastic waste, old packaging, plastic waste, cable waste.

Kunststoffmüll - Altkunststoffe fallen als Gemisch der unterschiedlichsten Kunststoffe in großen Mengen auf dem Verpackungssektor an wo sie einen unverzichtbaren Beitrag zum Schutz und der Verteilung von Lebensmitteln und anderer Waren übernehmen.Plastic waste - Waste plastics are a mixture of various plastics that are generated in large quantities in the packaging sector, where they make an indispensable contribution to the protection and distribution of food and other goods.

Die Menge der bisher zurückgewonnenen Kunststoffe konnte noch leidlich in untergeordnete Produkte uie z.B. Pflanzentöpfe verarbeitet uerden.The amount of plastic recovered so far could still be processed into subordinate products such as plant pots.

Die in Zukunft anfallenden Mengen können jedoch nur noch Sinnvoll untergebracht werden, uenn eine nahezu sortenreine Trennung durchgeführt wird, um sie zu hochwertigen Produkten zu verarbeiten.However, the quantities that will arise in the future can only be sensibly disposed of if they are separated into almost pure types in order to process them into high-quality products.

Die bisher bekanntesten Einrichtungen zum Trennen / Sortieren von Kunststoffen sind die Dichtetrennung im Schwimm - Sinkverfahren und das Hydrozyklonverfahren. Alle Flotationsverfahren haben den Nachteil, daß die getrennten Fraktionen naß anfallen und mit nicht unerheblichem Energieaufuand vor der Weiterverarbeitung getrocknet werden müssen. Außerdem können Kunststoffe wie z.B. Hd-PE und Nd-PE da ihre Dichte nahezu gleich ist praktisch mit diesen Verfahren nicht getrennt uerden.The best-known systems for separating/sorting plastics to date are density separation using the float-sink process and the hydrocyclone process. All flotation processes have the disadvantage that the separated fractions are wet and have to be dried before further processing, which requires a considerable amount of energy. In addition, plastics such as HDPE and NDC cannot be separated using these processes as their density is almost the same.

Aufgabe der Erfindung ist es eine Einrichtung zur trockenen Trennung / Sortierung won Kunststoffen zu schaffen die auch fast dichtegleiche Kunststoffe einfach und kostengünstig trennt und einen hohen Reinheitsgrad ermöglicht. The object of the invention is to create a device for the dry separation/sorting of plastics that separates even plastics with almost the same density easily and inexpensively and enables a high degree of purity.

Gemäß der Erfindung ist die Einrichtung zum Trennen won Feststoffen der eingangs genannten Art, mit der dies zu erreichen ist dadurch gekennzeichnet, daß als Trenngrundlage die unterschiedlichen Erweichungs / Schmelzpunkte der unterschiedlichen Kunststoffe ausgenützt uird.According to the invention, the device for separating solids of the type mentioned at the beginning, with which this is to be achieved, is characterized in that the different softening/melting points of the different plastics are used as the basis for separation.

Weitere Einzelheiten sind dem auf der einzigen Zeichnung schematisch in Seitenansicht dargestellten Ausführungsbeispiel zu entnehmen.Further details can be found in the embodiment shown schematically in side view in the single drawing.

Die in der Zeichnung in Seitenansicht schematisch dargestellte Einrichtung zum Trennen / Sortieren von rieselfähigen Feststoffen mit unterschiedlichen Erueichungs / Schmelzpunkten insbesondere von gemahlenen Kunststoffabfällen (1) besteht im wesentlichen aus einer beheizbaren in ihrer Drehzahl regelbaren Antriebsualze (2) und einer kühlbaren, gefederten Umlenkwalze (3). Den in ihrer Temperatur exakt regelbaren balligen Kühlbalken (14/15/16) und dem endlosen Aufgabeband (4) auf das vom Aufgabetrichter (5) durch die Dosierstreubürste (6) über Bohrungen oder in ihrer Breite einstellbaren Streuschlitzen (7) ein gleichmäßiger einlagiger Belag auf das Aufgabeband (4) aufgestreut uird der durch die Bandklopfbürste (8) gleichmäßig verteilt uird. Im Bereich der Bandheizung (9) uird das aufgestreute Kunststoff Mahlgut angeschmolzen und klebt auf dem Aufgabeband (4) fest. Das die beheizte Antriebswalze (2) mit Aufgabeband (4) umschlingende über die Laufrollen (10/11/12), v/on denen die Laufrolle (11) angefedert ist, laufende Andrückband (13) drückt die angeschmolzenen Kunststoffteile auf dem Aufgabeband (4) fest. Nicht plastifizierbare Teile wie Schmutz oder Steine fallen nach verlassen des Andrückbandes in den Schmutzbehälter (21).The device shown schematically in the drawing in side view for separating/sorting free-flowing solids with different melting/melting points, in particular ground plastic waste (1) consists essentially of a heatable drive roller (2) with adjustable speed and a coolable, spring-loaded deflection roller (3). The spherical cooling beam (14/15/16) with precisely adjustable temperature and the endless feed belt (4) onto which a uniform single-layer coating is spread from the feed hopper (5) through the dosing spreading brush (6) via holes or width-adjustable spreading slots (7) onto the feed belt (4) and evenly distributed by the belt beating brush (8). In the area of the belt heating (9) the spread plastic ground material is melted and sticks to the feed belt (4). The pressure belt (13) which wraps around the heated drive roller (2) with the feed belt (4) and runs over the rollers (10/11/12) on which the roller (11) is spring-loaded, presses the melted plastic parts onto the feed belt (4). Non-plasticizable parts such as dirt or stones fall into the dirt container (21) after leaving the pressure belt.

Die Temperatur der Kühlbalken (14/15/16) ist so eingestellt, daß sich eine Temperaturkaskade bildet. Die angeklebten Kunststoffteile fallen, beginnend mit den höchstschmelzenden, je nach Schmelztemperatur und unterstützt &ugr;&ogr;&eegr; den Abstreifbürstenualzen (17/18/19/20) in den ihnen zugeordneten Auffangbehälter (22/23/24/25) zur weiteren Verarbeitung.The temperature of the cooling beams (14/15/16) is set so that a temperature cascade is formed. The glued plastic parts fall, starting with the ones with the highest melting point, depending on the melting temperature and supported by the stripping brushes (17/18/19/20) into the associated collecting container (22/23/24/25) for further processing.
