Description

Eigenfrequenzförderer sind zur Förderung von Schüttgut geeignet. Für die vorliegende Trennaufgabe sind als Aufgabegut Partikelgemenge zerkleinerter Produkte oder auch einfache Produkte geeignet, die verstreckte Thermoplaste enthalten. Dabei können die verstreckten Thermoplaste sowohl vereinzelt als auch im Verbund mit anderen Materialien vorliegen, sofern durch die Relaxation eine Verbundtrennung erfolgt. Die Durchführung einer Verbundtrennung, die bei adhäsiven Verbundbauteilen auf der Nutzung der Schrumpfkraft als Schälspannung auf die Verbundfläche oder bei formschlüssigen Verbundbauteilen auf der Formänderung des schrumpfenden Thermoplasten beruht, kann durch die Vibration der Eigenfrequenzförderung unterstützt werden.Natural frequency conveyors are suitable for conveying bulk goods. For the This separation task is more comminuted as a batch of particles Suitable products or simple products, the stretched thermoplastics contain. The stretched thermoplastics can either be isolated also in combination with other materials, provided that the Relaxation a composite separation takes place. Carrying out a Compound separation, which is based on the use of the adhesive composite components Shrinkage force as peeling stress on the bonded surface or at positive composite components on the change in shape of the shrinking Thermoplastic based, can by the vibration of the natural frequency promotion get supported.

Das Aufgabegut wird auf ein Fließbett aufgegeben und dort während der Förderung auf die für das Relaxieren des zu sortierenden Thermoplasten notwendige Temperatur erwärmt. Bei der Relaxation stellt sich die gewünschte Verbundtrennung und/oder Volumenreduzierung des zu sortierenden Thermoplasten ein. Im Anschluß an dieses beheizte Fließbett gelangt das Fördergut auf ein Fließbett, daß mit einem Siebboden (Lochblech) versehen ist. Optional kann auch bereits daß Fließbett mit einem Sieb versehen sein, bei dem die Erwärmung stattfindet, so daß geschrumpfte Partikel direkt das Fließbett durch das Sieb passieren. Die relaxierten Thermoplastpartikel fallen durch das Sieb, während alle anderen Materialien weitergefördert werden. Der relaxierte Thermoplast kann somit separat abgeführt werden.The feed is placed on a fluid bed and there during the Funding for those to relax the thermoplastic to be sorted necessary temperature warmed. The relaxation is the desired one Compound separation and / or volume reduction of the to be sorted Thermoplastics. This comes after this heated fluidized bed Conveyed goods on a fluidized bed that is provided with a sieve bottom (perforated plate). Optionally, the fluidized bed can already be provided with a sieve, at which the heating takes place, so that shrunk particles directly the Pass the fluid bed through the sieve. The relaxed thermoplastic particles fall through the sieve while all other materials are being conveyed. Of the relaxed thermoplastic can thus be removed separately.

Liegen im Aufgabegut mehrere verstreckte Thermoplaste unterschiedlicher Sorten vor, so können diese durch Hintereinanderschaltung mehrerer erfindungsgemäßer Fließbettstrecken jeweils nach dem Durchlaufen der für den verstreckten Thermoplasten charakteristischen Relaxationstemperatur voneinander und aus dem Gemenge getrennt werden.If there are several stretched thermoplastics of different sizes in the feed Varieties before, so these can be connected in series by several fluidized bed sections according to the invention each after passing through the for stretched thermoplastics characteristic relaxation temperature be separated from each other and from the batch.

AnwendungsbeispielApplication example

Es sollen Schaumstoff-Flocken behandelt werden, wie sie aus der Zerkleinerung von Schaumstoffprodukten resultieren. In dem Aufgabegut liegen PS, PE, PP, PU und auch mineralische Schaumstoffe vor. Die Flockengröße beträgt durch die Verwendung eines Zerkleinerungsaggregates etwa 10×30×20 mm.Foam flakes are to be treated as they come from the Shredding of foam products result. Are in the feed  PS, PE, PP, PU and also mineral foams. The flake size is about by using a shredder 10 × 30 × 20 mm.

Es wird ein Wendelförderer eingesetzt, der drei Erwärmungszonen mit jeweils anschließenden Siebzonen hintereinander aufweist. In der ersten Erwärmungszone wird das Aufgabegut auf 100-105°C erwärmt, wodurch die PS- Flocken schrumpfen. Aufgrund der Vibrationen schrumpfen die Flocken immer als vereinzelte Partikel. In der anschließenden Siebstrecke wird das PS abgesiebt. In der nächsten Erwärmungsstrecke wird eine Temperatur von 135-140°C erreicht, wodurch das PE schrumpft und in der anschließenden Siebstrecke abgesiebt wird. In der dritten Erwärmungsstufe schrumpft das PP bei 150-160°C und wird anschließend abgesiebt.A spiral conveyor is used, each with three heating zones subsequent sieving zones one behind the other. In the first Warming zone, the feed material is heated to 100-105 ° C, whereby the PS Shrink flakes. Due to the vibrations, the flakes always shrink as isolated particles. In the subsequent sieve section, the PS sieved. In the next heating section a temperature of 135-140 ° C will be reached reached, causing the PE to shrink and in the subsequent Sieve section is screened. In the third warming stage, the PP shrinks at 150-160 ° C and is then sieved.

In der Überlauf-Fraktion verbleiben die PU und die mineralischen Schaumstoff-Focken sowie eventuelle Ettiketten oder Klebestreifen, die zuvor mit einem der separaierten Schaumstoffe im Verbund vorgelegen haben. Alle Thermoplasten wurden sortiert und können einem sortenreinen Umschmelzrecycling zugeführt werden.The PU and the mineral remain in the overflow fraction Foam jams as well as any labels or adhesive strips that were previously have been present in combination with one of the separated foams. All Thermoplastics have been sorted and can be sorted Remelt recycling can be fed.
