Abstract

In a new device for sepg. solid materials of different densities by flotation, the sepn. tank (1) is rounded at the top and bottom and has upper and lower rotating screws and paddles (2,3). Material is fed into the tank from an inlet hopper (4) by a screw conveyor (5). Light material mixed with the sinking heavy material, and heavy material mixed with the floating light material, are released by paddles (6,7). Screws (8,9) convey the sepd. materials into vertical tubes (10,11) in which they are removed from the tank by conveying screws (12,13). USE/ADVANTAGE - For sepg. materials such as chopped plastic waste, used packaging material, scrap electric cables or electronic material etc. A separation efficiency of 99.9% is achieved using a device which is simple and inexpensive and does not occupy a large space.

Description

Die Erfindung bezieht sich auf eine Einrichtung zur nahezu sorten­ reinen Trennung und Rückgewinnung von rieselfähigen Feststoffen unter­ schiedlichen Gewichts wie z. B. zerkleinerte und gemahlene Kunststoff­ abfälle, alte Verpackungen, Kunststoffmüll, Kabelabfälle.The invention relates to a device for almost varieties pure separation and recovery of free-flowing solids under different weights such. B. crushed and ground plastic waste, old packaging, plastic waste, cable waste.

Angesichts der auf unserer Erde nicht unendlich vorhandenen Rohstoffe und des, wenn wir unser Verhalten nicht ändern, unabwendbaren Müll­ notstandes ist es notwendig, Wertstoffe z. B. Kunststoffabfälle einer Wiederverwertung zu zuführen.In view of the raw materials that are not infinitely available on earth and, if we don't change our behavior, inevitable garbage in an emergency, it is necessary to recycle B. plastic waste one To recycle.

Die Wiederverwertung von Altstoffen wie Glas, Papier, Pappe und Me­ tallen ist gegenüber der Wiederverwertung von Kunststoffen einfach.The recycling of old materials such as glass, paper, cardboard and me tallen is easy compared to the recycling of plastics.

Kunststoffmüll - Altkunststoffe fallen als Gemisch der unterschied­ lichsten Kunststoffe an die ohne nahezu sortenreine Trennung nicht, oder wenn überhaupt nur zu minderwertigen Produkten verarbeitet wer­ den können.Plastic waste - old plastics fall as a mixture of differences most plastics to those without almost pure separation, or if at all only processed to inferior products that can.

Kunststoffe werden in mehrere Gruppen eingeteilt, die meistverwendeten sind:Plastics are divided into several groups, the most commonly used are:

Polyolefine zu denen Polyätylen, Polypropylen und Polybuten zählen, Styrol-Polymerisate, z. B. Polystyrol. Vinyl-Polymerisate, also hart und weich PVC.Polyolefins, which include polyethylene, polypropylene and polybutene, Styrene polymers, e.g. B. polystyrene. Vinyl polymers, i.e. hard and soft PVC.

Kunststoffabfälle - Altkunststoffe fallen in großen Mengen auf dem Verpackungssektor an wo sie einen unverzichtbaren Beitrag zum Schutz und der Verteilung von Lebensmitteln und anderer Waren übernehmen. Die Gewichtsreduzierung zur Senkung des Treibstoffverbrauches bei Kraftfahrzeugen wird besonders durch den vermehrten Einsatz von Kunst­ stoffen erreicht, schon heute entfallen etwa 20 % des Gewichtes eines PKW auf Kunststoffe, mit steigender Tendenz. Plastic waste - old plastics fall in large quantities on the Packaging sector where they make an indispensable contribution to protection and the distribution of food and other goods. The weight reduction to reduce fuel consumption Motor vehicles become particularly popular through the increased use of art fabrics reached, about 20% of the weight is already lost Cars on plastics, with increasing tendency.  

Kabelabfälle die in enormen Mengen anfallen wurden bisher zur Rückgewinnung des Kupfers unter Freisetzung von erheb­ lichen Schadstoffmengen abgebrannt.Cable waste that has arisen in enormous quantities so far to recover the copper with the release of considerable quantities of pollutants burned.

Die Menge der bisher zurückgewonnenen Kunststoffe konnte noch leidlich in untergeordnete Produkte wie z. B. Pflanzen­ töpfe verarbeitet werden.The amount of plastics recovered so far could still tolerably in subordinate products such. B. plants pots are processed.

Die in Zukunft anfallenden Mengen können jedoch nur noch sinnvoll untergebracht werden, wenn eine nahezu sortenreine Tren­ nung durchgeführt wird, um sie zu hochwertigen Produkten zu verarbeiten.However, the quantities that will arise in the future can only make sense be housed when an almost single door is carried out to make them high quality products to process.

haben zum einen den Nachteil, daß die Einrichtungen sehr groß und damit teuer sind, das größte Problem ist jedoch das aus­ tragen der getrennten Feststoffe die mit Flotationsflüssig­ keit ausgeschwemmt werden. Die mitausgetragene Flotationsflüs­ sigkeit muß in den Trennprozeß rückgeführt werden dabei ent­ stehen unvermeidliche Flüssigkeits-Turbulenzen die eine exakte Trennung unmöglich machen. Der mit solchen Anlagen erreichbare Reinheitsgrad liegt bei 90-95%.Previously known devices for separating solids of different weights z. B .:

have on the one hand the disadvantage that the facilities are very large and therefore expensive, but the biggest problem is that of carrying the separated solids which are washed out with flotation liquid. The co-discharged Flotationsflüs liquid must be returned to the separation process, resulting in unavoidable liquid turbulence which makes an exact separation impossible. The degree of purity that can be achieved with such systems is 90-95%.

Aufgabe der Erfindung ist es, eine Flotations-Trenneinrich­ tung zu schaffen die ohne großen Platzbedarf, einfach und kostengünstig einen Reinheitsgrad von über 99,9% ermöglicht. The object of the invention is to provide a flotation separator to create the easy and simple space enables a degree of purity of over 99.9% at low cost.  

Gemäß der Erfindung ist die Einrichtung zum Trennen von Fest­ stoffen unterschiedlichen Gewichts der eingangs genannten Art, mit der dies zu erreichen ist dadurch gekennzeichnet, daß ein vertikal stehender, oben und unten abgerundeter mit Flotationsflüssigkeit gefüllter Schwimm-Sink-Trennbehäl­ ter verwendet wird, in dem sich oben und unten angetriebene Schnecken und Paddelwellen befinden. Der Abstand der oberen und der unteren Schnecken und Paddelwellen zueinander sowie deren Drehzahl ist so bemessen, daß keine Turbulenzen das Aufsteigen oder Absinken der Feststoffe behindern.According to the invention, the device for separating solid substances different weights of the above Way in which this is achieved is characterized that a vertical, rounded top and bottom with Flotation liquid filled swim-sink separation container ter is used in the top and bottom driven Snails and paddle shafts are located. The distance of the top and the lower snails and paddle shafts to each other as well their speed is such that no turbulence Obstacles to rising or falling of the solids.

Die Zuführung der zu trennenden Feststoffe in den Schwimm- Sink-Trennbehälter aus dem Aufgabetrichter erfolgt durch den Schnecken-Einzugteil, das Ausbringen der getrennten Fraktionen in die Steigrohre durch Austragsschnecken.The feeding of the solids to be separated into the swimming Sink separation container from the hopper is done by the screw feed section, the spreading of the separated Fractions in the risers through discharge screws.

Das Austragen der getrennten Feststoffe aus den Steigrohren muß ohne Flotationsflüssigkeit erfolgen deshalb sind die Förder­ schnecken als Siebschnecken ausgebildet, beste Ergebnisse brachten kammartige Förderschnecken deren Stifte nur die Fest­ stoffe Fördern und Austragen.The discharge of the separated solids from the risers must be done without flotation liquid, therefore the funding snails designed as screen screws, best results brought comb-like screw conveyors whose pins only the hard conveying and discharging substances.

Ein, zum Verfolgen der Vorgänge aus Plexiglas, gefertigtes Modell mit einem Schwimm-Sink-Trennbehälter von 600 mm Höhe, 122 mm Breite und 800 mm Länge, wurde mit ca. 60 Liter Wasser als Flotationsflüssigkeit gefüllt. Das zu trennende saubere Kunststoffgemisch bestehend aus etwa 2/3 Polystyrol und 1/3 Polypropylenabfällen wurde bei einem Durchsatz von etwa 80 Kg/Stunde mit einer Reinheit von über 99,99% für beide Fraktionen problemlos getrennt.A made to follow the processes from plexiglass Model with a 600 mm floating sink separator Height, 122 mm width and 800 mm length, was about 60 liters Water filled as a flotation liquid. The one to be separated clean plastic mixture consisting of about 2/3 polystyrene and 1/3 polypropylene waste was at a throughput of about 80 kg / hour with a purity of over 99.99% for both fractions separated easily.

Weitere Einzelheiten sind den in den Zeichnungen dargestellten Ausführungsbeispielen von Einrichtungen zur nahezu sortenrei­ nen Trennung von Feststoffen unterschiedlichen Gewichts zu entnehmen. Further details are those shown in the drawings Examples of devices for almost varietal separation of solids of different weights remove.

Die in Fig. 1 in Seitenansicht und in Fig. 2 in Schnitt schema­ tisch dargestellte Einrichtung zur Trennung von rieselfähigen Feststoffen unterschiedlichen Gewichts besteht im wesentlichen aus einem vertikal stehenden, oben und unten abgerundeten, mit Flotationsflüssigkeit gefüllten Schwimm-Sink-Trenn­ behälter (1), in dem sich oben und unten angetriebene Schnec­ ken und Paddelwellen (2/3) befinden.The in Fig. 1 in side view and in Fig. 2 in section schematically shown device for separating free-flowing solids of different weights consists essentially of a vertically standing, rounded up and down, filled with flotation liquid floating-sink separation container ( 1 ) , in which there are driven worms and paddle shafts ( 2/3 ).

Die Zuführung der zu trennenden Feststoffe aus dem Aufgabe­ trichter (4) erfolgt über den Einzugsschneckenteil (5). Die auf der ganzen Länge des Trennbehälters (1) arbeitenden Pad­ del (6/7) durchmischen die aufgeschwommene und die abgesunkene Fraktion und setzen mitaufgeschwommene schwere und mitabge­ sunkene leichte Teile frei. Gleichzeitig befördern sie durch entsprechende Schrägstellung die zu trennenden Feststoffe von der Eingangs zur Ausgangsseite wo sie von den Austrags­ schnecken (8/9) erfaßt und den in den Steigrohren (10/11) befindlichen Förderschnecken (12/13) zugeführt werden.The solids to be separated are fed from the feed hopper ( 4 ) via the feed screw part ( 5 ). The pad del ( 6/7 ) working along the entire length of the separation container ( 1 ) mix the floated and the sunken fraction and release heavy and co-sunken light parts. At the same time, they convey the solids to be separated from the entrance to the exit side where they are screwed by the discharge ( 8/9 ) and are fed to the screw conveyors ( 12/13 ) located in the risers ( 10/11 ).

Da der Trennbehälter (1) und die Steigrohre (10/11) mitein­ ander verbunden sind, steht in beiden das Niveau der Flotations­ flüssigkeit gleich hoch. Das Austragen der getrennten Fest­ stoffe erfolgt durch die kammartigen Förderschnecken (12/13). Fig. 4 welche nur die abgetropften Feststoffe austragen die nach separater Trocknung weiterverarbeitet werden. Since the separation container ( 1 ) and the risers ( 10/11 ) are connected to each other, the level of the flotation liquid is the same in both. The separated solids are discharged through the comb-like screw conveyors ( 12/13 ). Fig. 4 which only discharge the drained solids which are further processed after separate drying.

Bei der in Fig. 3 dargestellten Variante werden die zu tren­ nenden Feststoffe aus dem Aufgabetrichter (4) über das Zuführ­ rohr (14) dem Trennbehälter (1) unten zugeführt. Verschmutzte Abfälle werden dabei in der Waschstrecke (15) gewaschen. Die leichtere Fraktion schwimmt im Trennbehalter (1) auf, mitauf­ geschwommene schwere Teile werden auf der Paddelstrecke frei­ gesetzt und können absinken. Das Austragen der leichten Frak­ tion erfolgt wie bei Fig. 1.In the variant shown in FIG. 3, the solids to be separated are fed from the feed hopper ( 4 ) via the feed pipe ( 14 ) to the separation container ( 1 ) below. Contaminated waste is washed in the washing section ( 15 ). The lighter fraction floats up in the separation container ( 1 ), heavy parts that are floating on it are released on the paddle route and can sink. The light fraction is carried out as in FIG. 1.

Der schwere Fraktionsanteil und der Schmutz bleiben aufgrund ihres Gewichtes im Trennbehälter (1) unten und werden im Be­ darfsfalle durch einen weiteren Trennbehälter mit angepaßter Flotationsflüssigkeit geführt in dem wieder die leichtere Fraktion durch aufschwimmen getrennt wird. Die verbliebene Restfraktion aus Schmutz, Fremdkörper und z. B. PVC wird nach Trocknung einer thermischen Verwertung oder der Deponie zuge­ führt.The heavy fraction and the dirt remain in the separation tank ( 1 ) due to their weight and, if necessary, are passed through another separation tank with an adapted flotation liquid in which the lighter fraction is separated again by floating. The remaining fraction of dirt, foreign bodies and z. B. PVC is fed to a thermal recovery or landfill after drying.
