Abstract
Le procédé proposé prévoit de laisser s'écouler le flux de produit en vrac en une couche plate, sous l'influence de la force centrifuge, sur une surface inclinée par rapport à la verticale et garnie de pointes, qui se déplace à l'encontre du sens d'écoulement du produit en vrac. Le procédé peut être mis en oeuvre au moyen d'un cylindre 1 garni extérieurement de pointes 2, disposé sous une ouverture de sortie 5 de produit en vrac, en forme de fente.The proposed method provides for allowing the flow of bulk product to flow in a flat layer, under the influence of centrifugal force, on a surface inclined from the vertical and lined with spikes, which moves against the direction of flow of the bulk product. The method can be implemented by means of a cylinder 1 lined on the outside with tips 2, arranged under an outlet opening 5 for bulk product, in the form of a slot.
Description
La présente invention concerne un procédé pour la séparation de "cheveuxThe present invention relates to a method for the separation of "hair
d'ange" de produits en vrac, etangel "of bulk products, and
un separateur pour la mise en oeuvre de ce procédé. a separator for the implementation of this method.
Pour différents produits en vrac, notamment pour des granules de matiere plastique, il s'opere fréquemment, au cours du transfert generalement pneumatique du produit, une abrasion par frottement appelée "cheveux d'ange", cui peuvent avoir des longueurs atteignant un metre. Comme ces cheveux d'ange engendrent des perturbations considérables lorsque le produit en vrac est sorti. de silos de stockage, ainsi que lors de l'ensachage et de traitements ultérieurs, il faut les enlever. A cet effet, on sait que l'on peut tamiser le produit en vrac. Mais les tamls correspondants présentent des dimensions constructives très importantes. Une autre possibilité consiste & employer des aerc-séparateurs, mais on ne peut pas toujours obtenir ainsi des coefficients de séparation satisfaisants. La présente invention a pour but de fournir un procédé, ainsi qu'un separateur pour la mise en oeuvre de ce procédé, qui ne presentent pas les inconvénients précites. Selon l'invention., ce but est atteint au moyen d'un procéde qui est caractérise en ce qu'on laisse s'écouler le flux de produit en vrac en une couche plate, sous l'influence de la force centrifuge, sur une surface inclinée par rapport à la verticale et garnie de pointes, qui se déplace à l'encontre du sens For various bulk products, especially for granules of plastic material, it frequently occurs, during the generally pneumatic transfer of the product, abrasion by friction called "angel hair", which may have lengths up to one meter. As this angel hair causes considerable disruption when the bulk product is released. of storage silos, as well as during bagging and subsequent treatments, must be removed. For this purpose, it is known that the product in bulk can be sieved. But the corresponding tamls have very significant constructive dimensions. Another possibility is to use separators, but satisfactory separation coefficients can not always be obtained. The present invention aims to provide a method and a separator for the implementation of this method, which do not have the aforementioned drawbacks. According to the invention, this object is achieved by means of a process which is characterized in that the flow of bulk product is allowed to flow in a flat layer, under the influence of the centrifugal force, on a surface inclined to the vertical and spiked, which moves against the direction
d'écoulement du produit en vrac.flow of the bulk product.
Pour la mise en oeuvre de ce procédé, l'invention propose un séparateur qui est caractérisé en ce qu'il comprend un cylindre rotatif garni extérieurement de pointes, qui est disposé sous une ouverture de sortie de produit en vrac en forme de fente de telle sorte que le flux de produit en vrac s'écoule vers le bas sur la partie ascendante de la periphérie du cylindre. Selon une autre forme de réalisation possible, le séparateur comprend un cylindre creux rotatif garni intérieurement de pointes, dont l'axe est incliné par. rapport à l'horizontale. et qui est muni sur sa face frontale surelevee d'une ouverture d'entrée, et sur sa face frontale abaissée d'une ouverture de sortie pour le For the implementation of this method, the invention provides a separator which is characterized in that it comprises an externally-packed rotary cylinder of points, which is arranged under a slit-shaped bulk product outlet opening of such so that the flow of bulk product flows downward on the upward part of the peripheria of the cylinder. According to another possible embodiment, the separator comprises a rotary hollow cylinder lined internally with points, whose axis is inclined by. report horizontally. and which is provided on its raised front face with an inlet opening, and on its lowered end face with an outlet opening for the
produit en vrac.bulk product.
Le procédé se caractérise notamment par un faible coût et des coefficients de séparation élevés, et les séparateurs ont l'avantage de présenter un faible The process is characterized in particular by a low cost and high separation coefficients, and the separators have the advantage of having a low
encombrement.footprint.
Les dessins annexes représentent d'une manière simplifiée des séparateurs pour la mise en oeuvre du procedé selon l'invention, et dans lesquels: la figure 1 représente une première forme de réalisation, et la figure 2 représente une deuxième forme de réalisation. Le séparateur selon la figure 1 est constitué d'un cylindre ou tambour 1, qui peut aussi éventuellement être réalisé creux, dont la périphérie extérieure est garnie de nombreuses et longues pointes 2. Le cylindre The accompanying drawings show in a simplified manner separators for the implementation of the method according to the invention, and in which: Figure 1 shows a first embodiment, and Figure 2 shows a second embodiment. The separator according to FIG. 1 consists of a cylinder or drum 1, which can also optionally be hollow, whose outer periphery is packed with numerous long spikes 2. The cylinder
tourne autour de son axe 3 dans le sens de la flèche 4. rotate around its axis 3 in the direction of arrow 4.
Le cylindre 1 est disposé sous une ouverture 5 de sortie d'un produit en vrac, en forme de fente de telle sorte que le produit en vrac s'ecoule en une couche plate sur la partie ascendante de la périphérie du cylindre 1, sous l'influence de la force centrifuge, pour être dirige vers le bas dans un entonnoir 6 ou similaire. De la sorte, les cheveux d'ange présents dans le produit en vrac sont en quelque sorte "enleves par peignage". Les cheveux d'angle qui restent accroches sur les pointes peuvent être évacués sur le côté descendant de la periphérie du cylindre, a l'aide de dispositifs auxiliaires non représentés. Il peut s'agir là d'évacuation par aspiration ou par soufflage d'air, ou encore par brossage. Il est particulièrement avantageux de combiner le séparateur avec un dispositif de The cylinder 1 is disposed under an outlet opening 5 of a bulk product, in the form of a slit so that the bulk product flows into a flat layer on the upward part of the periphery of the cylinder 1, under the influence of the centrifugal force, to be directed downwards in a funnel 6 or the like. In this way, the angel hair present in the bulk product is somehow "removed by combing". The corner hair that hangs on the tips can be discharged on the downward side of the periphérie of the cylinder, using auxiliary devices not shown. This may be evacuation by suction or air blowing, or by brushing. It is particularly advantageous to combine the separator with a device for
depoussiérage (egalement non represente. dusting (also not shown.
Le séparateur représente sur la figure 2 fonctionne selon le même procéde que celui de la figure 1. Il est k5 constitue d'un cylindre creux 21, dont l'axe est incline par rapport à l'horizontale, et dont la face d'enveloppe intérieure est garnie de pointes 22 tournees radialement vers l'intérieur. Le cylindre creux tourne dans le sens de la flèche 24. Dans la face frontale surélevée du cylindre I se trouve une ouverture d'entree pour le produit en vrac s'écoulant a partir d'un silo 25, et le produit quitte le cylindre creux 21 par l'autre face frontale ouverte abaissee de ce dernier, et il est par exem=le recueilli a l'aide d'un entonnoir 20. Ici aussi, le nettoyage des pointes peut s'effectuer à l'aide des dispositifs auxiliaires cités dans le cadre de la figure 1. Cette forme de réalisation convient tout particulièrement pour une combinaison avec un The separator shown in FIG. 2 operates according to the same process as that of FIG. 1. It is constituted of a hollow cylinder 21, whose axis is inclined with respect to the horizontal, and whose envelope face Inside is filled with 22 spikes turning radially inwards. The hollow cylinder rotates in the direction of the arrow 24. In the raised end face of the cylinder I is an inlet opening for the bulk product flowing from a silo 25, and the product leaves the hollow cylinder 21 by the other open end face of the latter, and it is for example collected by means of a funnel 20. Here too, the cleaning of the tips can be performed using the auxiliary devices mentioned in the context of Figure 1. This embodiment is particularly suitable for a combination with a
dépoussiérage simultané du produit en vrac. simultaneous dedusting of the bulk product.
