Abstract

A method of separating angels' hair from bulk goods includes the step of causing the stream of bulk goods to flow in a layer and under the influence of gravity over a surface occupied by spines and inclined in respect of the vertical and which is moving with respect to the direction of flow of the bulk goods in order to remove angels' hair from the flow of the bulk goods. The method can be carried out by means of a rotatable cylinder (1) on the outside surface of which there are spines (2) and which is situated under a slot-like bulk goods outflow orifice (5), or (Fig. 2, not shown) by means of a rotatable cylinder whose inside surface carries spines and which is on an inclination, with material fed into it at the higher end. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zur Abscheidung von sogenanntem Engelhaar aus Schüttgut und Abscheider zur Durchführung dieses Verfahrens.The invention relates to a method for deposition of so-called angel hair from bulk material and separator to carry out this procedure.

Bei verschiedenen Schüttgütern, insbesondere bei Kunst­ stoffgranulaten entsteht im Verlauf der üblichen pneu­ matischen Flugförderung häufig ein fadenförmiger Ab­ rieb, der als Engelhaar bezeichnet wird und Längen bis zu einem Meter haben kann. Da dieses Engelhaar bei der Entspeicherung des Schüttgutes aus Silos sowie bei der Absackung und Weiterverarbeitung zu erheblichen Störungen führt, muß es entfernt werden. Bekannt ist es, das Schüttgut zu diesem Zweck zu sieben. Allerdings bauen entsprechende Siebe sehr groß. Eine andere be­ kannte Möglichkeit besteht in der Verwendung von Windsichtern, jedoch lassen sich hiermit nicht immer zufriedenstellende Abscheidegrade erzielen.With various bulk goods, especially with art Material granules are formed in the course of the usual pneu Matic flight promotion often a thread-like Ab rubbed, which is called angel hair and lengths can have up to one meter. Because this angel hair in the storage of bulk goods from silos as well significant in bagging and further processing Leads to interference, it must be removed. It is known sieve the bulk material for this purpose. Indeed build corresponding screens very large. Another be Known possibility is to use Air classifiers, however, cannot always be used with this achieve satisfactory degrees of separation.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren sowie Abscheider zur Durchführung dieses Verfahrens zu schaffen, die die vorgenannten Nachteile nicht aufwei­ sen.The invention has for its object a method as well as separators to carry out this process create, which do not have the aforementioned disadvantages sen.

Die verfahrensmäßige Lösung dieser Aufgabe ist im kenn­ zeichnenden Teil des Patentanspruches 1 angegeben.The procedural solution to this problem is in the kenn drawing part of claim 1 specified.

Abscheider zur Durchführung des Verfahrens sind Gegen­ stand der Ansprüche 2 bzw. 3.Separators to carry out the process are opposed state of claims 2 and 3 respectively.

Das Verfahren zeichnet sich durch geringen Aufwand und hohe Abscheidegrade aus. Die Abscheider haben den Vorteil eines geringen Platzbedarfes.The process is characterized by little effort and high degrees of separation. The separators have the advantage a small footprint.

In der Zeichnung sind Abscheider zur Durchführung des Verfahrens nach der Erfindung vereinfacht dargestellt. Es zeigt:In the drawing there are separators for carrying out the The method according to the invention is shown in simplified form. It shows:

Fig. 1 eine erste Ausführungsform und Fig. 1 shows a first embodiment and

Fig. 2 eine zweite Ausführungsform. Fig. 2 shows a second embodiment.

Der Abscheider nach Fig. 1 besteht aus einer - gegebe­ nenfalls auch hohl ausgebildeten - Walze oder Trommel, deren Außenumfang mit zahlreichen langen Stacheln 2 besetzt ist. Die Walze dreht sich um ihre Achse 3 in Richtung des Pfeiles 4. Die Walze 1 ist derart unter einer schlitzförmigen Schüttgutausströmöffnung 5 ange­ ordnet, daß das Schüttgut in einer flachen Schicht über den ansteigenden Teil des Umfanges der Walze 1 unter dem Einfluß der Schwerkraft nach unten in einen Trichter 6 oder dgl. strömt. Hierbei wird in dem Schütt­ gut vorhandenes Engelhaar gewissermaßen ausgekämmt. Das in den Stacheln hängenbleibende Engelhaar kann auf der absteigenden Seite des Walzenumfanges mittels nicht dargestellter Hilfsvorrichtungen entfernt werden. In Betracht kommen insbesondere Absaugen oder Abblasen mittels Luft sowie Abbürsten. Besonders vorteilhaft ist eine Kombination des Abscheiders mit einer Entstaubungs­ vorrichtung (ebenfalls nicht dargestellt). The separator according to Fig. 1 consists of a - possibly also hollow - roller or drum, the outer circumference of which is occupied by numerous long spikes 2 . The roller rotates about its axis 3 in the direction of arrow 4 . The roller 1 is arranged under a slit-shaped bulk material discharge opening 5 that the bulk material flows in a flat layer over the rising part of the circumference of the roller 1 under the influence of gravity down into a funnel 6 or the like. Here, angel hair that is well present in the bulk is combed out, as it were. The angel hair stuck in the spines can be removed on the descending side of the roller circumference by means of auxiliary devices (not shown). In particular, suction or blowing off with air and brushing are considered. A combination of the separator with a dedusting device (likewise not shown) is particularly advantageous.

Der in Fig. 2 dargestellte Abscheider arbeitet nach dem gleichen Verfahren wie derjenige nach Fig. 1. Er besteht aus einer Hohlwalze 21, deren Achse gegen die Horizontale geneigt ist und deren innere Mantelfläche mit radial nach innen weisenden Stacheln 22 besetzt ist. Die Hohlwalze dreht sich in Richtung des Pfeiles 24. In der höherlie­ genden Stirnfläche befindet sich eine Eintrittsöffnung für das aus einem Silo 25 abströmende Schüttgut, das die Hohlwalze 21 über deren offenen Stirnfläche an der tieferliegenden Seite verläßt und z.B. mittels eines Trichters 26 aufgefangen wird. Auch hier kann das Ab­ reinigen der Stacheln mittels der im Zusammenhang mit Fig. 1 genannten Hilfsvorrichtungen erfolgen. Diese Ausführungsform eignet sich im besonderen Maße zur Kombination mit einer gleichzeitigen Entstaubung des Schüttgutes.The separator shown in FIG. 2 works according to the same method as that according to FIG. 1. It consists of a hollow roller 21 , the axis of which is inclined towards the horizontal and the inner lateral surface of which is covered with spikes 22 pointing radially inwards. The hollow roller rotates in the direction of arrow 24 . In the higher lying end face there is an inlet opening for the bulk material flowing out of a silo 25 , which leaves the hollow roller 21 via its open end face on the lower side and is collected, for example, by means of a funnel 26 . Here too, the spines can be cleaned by means of the auxiliary devices mentioned in connection with FIG. 1. This embodiment is particularly suitable for combination with a simultaneous dedusting of the bulk material.
