Description

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention concerne un dispositif destiné à séparer les mélanges hétérogènes de matériaux selon leur densité par rapport à celle d'un fluide.  The present invention relates to a device for separating heterogeneous mixtures of materials according to their density relative to that of a fluid.

CONTEXTE DE L'INVENTION Actuellement, certains matériaux de rebut tels que les déblais et équivalents ne sont pas exploités et sont directement déposés dans une décharge, avec les frais que ceci engendre.  BACKGROUND OF THE INVENTION Currently, some scrap materials such as cuttings and the like are not exploited and are directly deposited in a landfill, with the expense that this entails.

Dans le cas du déblai, qui est constitué par un mélange hétérogène de briques, de bois, de plastiques et autres impuretés, celui-ci serait, une fois propre, c'est-à-dire lorsque ces impuretés ont été éliminées, une matière première bénéfique pour réaliser des empierrements de couches de base ou de couches de fondation de voies ou de rues ou dans des bordures d'un type quelconque.  In the case of excavation, which consists of a heterogeneous mixture of bricks, wood, plastics and other impurities, it would be, once clean, that is to say when these impurities have been removed, a material first beneficial for making bedding base layers or foundation layers of roads or streets or in any type of borders.

Cependant, cette exploitation n'est pas possible étant donné que l'existence d'impuretés elle-même compromettrait la stabilité et la consistance de la couche base ou de la couche de fondation.  However, this exploitation is not possible since the existence of impurities itself would compromise the stability and consistency of the base layer or the base layer.

Il est possible de remédier à cet inconvénient en utilisant le dispositif de l'invention.  This disadvantage can be remedied by using the device of the invention.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Le dispositif de l'invention propose une manière optimale pour séparer, selon leur densité par rapport à celle d'un fluide, des matériaux mélangés de façon hétérogène, qui permet également d'éviter le soulèvement de poussière, et qui est spécialement utile pour supprimer les impuretés présentes dans les déblais et permettre une exploitation ultérieure.  The device of the invention provides an optimum way of separating, according to their density from that of a fluid, heterogeneously mixed materials, which also makes it possible to avoid the raising of dust, and which is especially useful for removing the impurities present in the cuttings and allow a subsequent exploitation.

Selon l'invention, le dispositif comporte une cuve susceptible d'être remplie du fluide de densité de référence, idéalement d'eau.  According to the invention, the device comprises a tank that can be filled with the reference density fluid, ideally water.

Afin de changer ce fluide ou de remplir de fluide, ou de directement vider la cuve pour le nettoyage, des conduits de remplissage et de vidage sont prévus, qui incorporent évidemment des éléments destinés à interrompre l'écoulement.  In order to change this fluid or fill fluid, or directly empty the tank for cleaning, filling and emptying channels are provided, which obviously incorporate elements to interrupt the flow.

La cuve incorpore une zone, de préférence centrale, dans laquelle est versé le mélange de matériaux que l'on souhaite séparer. Idéalement, le mélange est versé dans une trémie, ce qui réduit le soulèvement et la dispersion de poussière.  The tank incorporates a zone, preferably central, in which is poured the mixture of materials that it is desired to separate. Ideally, the mixture is poured into a hopper, which reduces uplift and dust dispersion.

Lorsqu'ils tombent dans le fluide, les matériaux de densité plus élevée décantent, alors que ceux de densité inférieure flottent, étant extraits vers des zones différenciées moyennant des convoyeurs à bande motorisés.  As they fall into the fluid, the higher density materials decant, while the lower density materials float, being extracted to differentiated areas by means of motorized belt conveyors.

La bande qui collecte les produits décantés circule au fond de la cuve, collectant ces matériaux, alors que la bande qui collecte les produits flottants reçoit l'aide de moyens qui poussent ces matériaux jusqu'à celle-ci et qui peuvent être des moyens mécaniques, de soufflage, ou tout autre moyen du domaine public qui sert pour cette fin.  The strip which collects the decanted products circulates at the bottom of the tank, collecting these materials, while the band which collects the floating products receives the aid of means which push these materials up to this one and which can be mechanical means , blowing, or any other means of the public domain that serves for this purpose.

La poussière qui peut rester en suspension et qui décante plus lentement peut se déposer, avec le temps, au fond de la cuve, il sera par conséquent nécessaire de nettoyer et d'éliminer périodiquement ces restes, ce pour quoi la cuve est munie d'une trappe contrôlable.  Dust that can remain in suspension and decant more slowly can be deposited, with time, at the bottom of the tank, it will therefore be necessary to clean and remove periodically these remains, what the tank is equipped with a controllable hatch.

BREVE DESCRIPTION DES DESSINSBRIEF DESCRIPTION OF THE DRAWINGS

La figure illustre une vue latérale schématique du 30 dispositif de l'invention.  The figure illustrates a schematic side view of the device of the invention.

DESCRIPTION D'UN MODE DE REALISATION DE L'INVENTION Le dispositif 1 de la présente invention est constitué par une cuve 2 qui peut être remplie d'un fluide 3 de densité déterminée, de préférence d'eau, dont la densité servira pour effectuer la séparation par flottaison et décantation d'un mélange de déblai et d'impuretés d'une taille de grains comprise entre 8 et 200 mm, la cuve comprenant un ou plusieurs conduits de remplissage et de vidage, avec les robinets de coupure correspondants, non représentés.  DESCRIPTION OF AN EMBODIMENT OF THE INVENTION The device 1 of the present invention is constituted by a tank 2 which can be filled with a fluid 3 of determined density, preferably water, the density of which will be used to effect the separation by flotation and settling of a mixture of cuttings and impurities with a grain size between 8 and 200 mm, the vessel comprising one or more filling and emptying conduits, with the corresponding shut-off valves, not shown .

La cuve 2 incorpore une zone de décharge du mélange du matériau à séparer. En l'espèce, la cuve 2 incorpore un montant central 4 pour une trémie 5 d'entrée du mélange de déblai, préférentiellement située en haut de la cuve 2 et dans l'ouverture de laquelle ce dernier peut être déchargé, par exemple, depuis un convoyeur à bande qui n'est pas représenté.  The tank 2 incorporates a discharge zone of the mixture of the material to be separated. In this case, the tank 2 incorporates a central upright 4 for an inlet hopper 5 of the cuttings mixture, preferably located at the top of the tank 2 and in the opening of which the latter can be discharged, for example, from a conveyor belt that is not represented.

A l'intérieur de la cuve, sont disposés des convoyeurs à bande motorisés 6, 7 qui extraient respectivement les matériaux qui flottent d'un côté (bois, plastique) et les matériaux décantés de l'autre (déblai, produit de lavage), jusqu'à des zones différenciées 8, 9 où ils peuvent être collectés séparément.  Inside the tank are arranged motorized belt conveyors 6, 7 which respectively extract the materials which float on one side (wood, plastic) and the materials decanted on the other (cuttings, detergent), to differentiated areas 8, 9 where they can be collected separately.

Pour aider à la collecte des matériaux flottants, on peut prévoir des moyens qui aident à accumuler les matériaux flottants. En l'espèce, on dispose dans la cuve un rouleau 10 motorisé et doté de pales radiales il, de préférence perforées, qui battent la superficie du fluide dans la direction adaptée pour conduire ces matériaux qui flottent vers la bande 6 du convoyeur correspondant.  To assist in the collection of floating materials, means can be provided to help accumulate floating materials. In the present case, a motorized roll 10 is provided in the vessel and provided with radial blades 11, preferably perforated, which beat the surface of the fluid in the direction adapted to drive these floating materials towards the strip 6 of the corresponding conveyor.

Pour leur part, les matériaux décantés sont directement collectés sur la bande du convoyeur 7 correspondant, étant donné que celle-ci parcourt aussi la partie du fond de la cuve 2.  For their part, the decanted materials are directly collected on the conveyor belt 7 corresponding, since it also travels the bottom part of the tank 2.

La cuve 2 comprend, finalement, une trappe latérale, non représentée, pouvant être utilisée pour le contrôle et le nettoyage de la poussière ou autres matériaux de décantation plus lente, dans le fond.  The tank 2 comprises, finally, a side hatch, not shown, which can be used for the control and cleaning of dust or other slower settling material in the bottom.

La nature de l'invention étant suffisamment décrite, tout comme la manière de la mettre en pratique, il faut remarquer que les détails des dispositions indiquées ci-avant et représentées sur les dessins joints sont susceptibles de modifications dans la mesure où ces modifications n'affectent pas le principe fondamental.  The nature of the invention being sufficiently described, as the manner of putting it into practice, it should be noted that the details of the provisions indicated above and shown in the accompanying drawings are subject to change insofar as these modifications do not affect the fundamental principle.
