Description

La présente invention concerne un nouveau séparateur hydraulique qui permet la séparation d'éléments de densités différentes à l'aide d'un liquide tel que l'eau.The present invention relates to a new hydraulic separator which allows the separation of elements of different densities using a liquid such as water.

Pour effectuer le classement de tels produits, il existe actuellement plusieurs types d'appareils dont ceux basés sur des techniques gravimétriques.To classify such products, there are currently several types of devices, including those based on gravimetric techniques.

Une première catégorie d'appareils pour séparer des éléments de densités différentes est constituée par les hydroclasseurs qui utilisent la différence de sédimentation dans un liquide, en général de l'eau. Ces appareils, de conception simple, ne peuvent être employés que pour séparer des produits fins du fait que le classement de ces produits a lieu par équivalence, c'est-à-dire selon le poids et non selon la densité des particules.A first category of apparatus for separating elements of different densities is constituted by hydro-classifiers which use the difference in sedimentation in a liquid, generally water. These devices, of simple design, can only be used to separate fine products from the fact that the classification of these products takes place by equivalence, that is to say by weight and not according to the density of the particles.

Une deuxième catégorie d'appareils est constituée par les tables, dormantes ou à secousses, qui séparent les produits par entraînement des éléments moins denses par un film fluide. Le principal inconvénient de ces appareils est de ne traiter que des particules fines ou relativement fines, c'est-à-dire de diamètre inférieur à 3 millimètres.A second category of apparatus consists of tables, dormant or shaking, which separate the products by entrainment of the less dense elements by a fluid film. The main drawback of these devices is that they only treat fine or relatively fine particles, that is to say with a diameter of less than 3 millimeters.

Comme autre type d'appareils, on peut citer les tables pneumatiques qui sont basées sur le principe des couloirs vibrants inclinés, la pente ascendante étant le sens de déplacement des produits restant en contact avec l'appareil. Les particules légères sont fluidisées par l'air qui traverse la table, s'éloignent de celle-ci et sont dirigées par ce courant d'air vers la partie basse de la table pneumatique. Les produits les plus denses restent en contact et sont sollicités par les vibrations : de ce fait ils remontent l'appareil et s'évacuent à sa partie supérieure. Ces appareils ne traitent que des produits qui sont de dimension inférieure à 60 millimètres et qui sont très secs.As another type of device, mention may be made of pneumatic tables which are based on the principle of inclined vibrating lanes, the upward slope being the direction of movement of the products remaining in contact with the device. Light particles are fluidized by the air which passes through the table, moves away from it and is directed by this current of air towards the lower part of the pneumatic table. The densest products remain in contact and are stressed by vibrations: thus they raise the device and evacuate to its upper part. These devices only process products that are less than 60 millimeters in size and that are very dry.

Enfin, nous citerons les appareils basés sur le principe suivant : les matériaux à classer sont distribués à la surface d'un fluide ou d'une suspension dont la densité est égale à celle de la séparation, la fraction de densité supérieure précipitant alors que celle de densité inférieure flotte. Si le principe est simple, son application pratique est assez compliquée et nécessite l'utilisation de nombreux dispositifs auxiliaires. Ces appareils peuvent classer des produits de toute dimension, en théorie tout au moins.Finally, we will mention devices based on the following principle: the materials to be classified are distributed over the surface of a fluid or suspension whose density is equal to that of separation, the higher density fraction precipitating while that of lower density floats. If the principle is simple, its practical application is quite complicated and requires the use of many auxiliary devices. These devices can classify products of any size, in theory at least.

Comme on peut le constanter, tous ces appareils de l'art antérieur présentent un certain nombre d'inconvénients qu'ils ont pour la plupart en commun : notamment le fait de ne pouvoir traiter que des produits de faible dimension, de comprendre des organes mécaniques en mouvement, compliqués et consommateurs d'énergie, d'être de réglage difficile et de ne pouvoir être alimentés en produits de formes tourmentées ou ayant tendance à s'agglomérer entre eux.As can be seen, all these devices of the prior art have a certain number of disadvantages which they have for the most part in common: in particular the fact of being able to treat only small products, of comprising mechanical organs moving, complicated and consuming energy, being difficult to adjust and not being able to be supplied with products of tormented forms or having a tendency to agglomerate with one another.

Aussi un des buts de la présente invention est un séparateur hydraulique qui permette la séparation densimétrique de particules grossières et de forme tourmentée.Also one of the aims of the present invention is a hydraulic separator which allows the densimetric separation of coarse and tormented particles.

Un autre but de l'invention est un séparateur de ce type qui soit simple à régler et facile à conduire.Another object of the invention is a separator of this type which is simple to adjust and easy to drive.

Un objet de la présente invention est un séparateur hydraulique qui ne comporte aucune partie mobile en relation directe avec la séparation.An object of the present invention is a hydraulic separator which has no moving part in direct relation to the separation.

Un autre objet de cette invention est un séparateur de ce type qui soit robuste, simple et d'utilisation économique.Another object of this invention is a separator of this type which is robust, simple and of use economic.

Ces buts et ces objets, ainsi que d'autres qui apparaîtront par la suite, sont atteints par un séparateur hydraulique selon la présente invention qui est constitué par une cuve de section transversale rectangulaire de largeur constante et dont la section verticale est un trapèze rectangle, la grande base correspondant à la partie haute de cette cuve, laquelle comporte à l'extrémité haute de son côté incliné et au-dessous de son bord supérieur un déversoir ; une cheminée qui est prolongée à sa partie supérieure, située au-dessous du niveau du bord supérieur de cette cuve, par une goulotte d'évacuation des éléments légers ; le séparateur comprenant également un système pour évacuer les éléments lourds, un dispositif pour injecter un liquide et des moyens pour introduire les produits à séparer.These objects and these objects, as well as others which will appear subsequently, are achieved by a hydraulic separator according to the present invention which is constituted by a rectangular cross-section tank of constant width and whose vertical section is a rectangular trapezoid, the large base corresponding to the upper part of this tank, which comprises at the upper end of its inclined side and below its upper edge a weir; a chimney which is extended at its upper part, situated below the level of the upper edge of this tank, by a chute for evacuating light elements; the separator also comprising a system for removing heavy elements, a device for injecting a liquid and means for introducing the products to be separated.

Avantageusement, la cheminée est un parallélépipède à section carrée dont le bord supérieur opposé à la goulotte d'évacuation est prolongé par les moyens pour introduire les produits à séparer qui sont constitués par un canal, faiblement incliné par rapport à l'horizontale.Advantageously, the chimney is a parallelepiped with a square section, the upper edge opposite to the discharge chute is extended by the means for introducing the products to be separated which consist of a channel, slightly inclined relative to the horizontal.

De préférence, le système pour évacuer les éléments lourds est constitué par une chaîne à raclettes qui est montée sur trois rouleaux : un d'eux étant situé au-dessus de la petite base de la cuve, les deux autres au-dessus de cette cuve dont un au-dessus du déversoir et un des deux étant moteur.Preferably, the system for removing heavy elements consists of a squeegee chain which is mounted on three rollers: one of them being located above the small base of the tank, the other two above this tank including one above the weir and one of the two being motor.

Avantageusement, cette cuve comprend en outre un déflecteur situé sous la cheminée et au-dessus du rouleau de renvoi disposé au-dessus de la petite base de cette cuve, ainsi que deux bavettes fixées le long des deux faces de la cuve de telle sorte que les éléments lourds s'accumulent et restent sur le trajet des raclettes.Advantageously, this tank further comprises a deflector located under the chimney and above the deflection roller disposed above the small base of this tank, as well as two flaps fixed along the two faces of the tank so that heavy elements accumulate and remain on the squeegee path.

Quant au dispositif pour injecter un liquide, il est de préférence situé en un point de la cuve tel que l'arrivée du liquide ne gêne pas la décantation des produits lourds.As for the device for injecting a liquid, it is preferably located at a point in the tank such that the arrival of the liquid does not interfere with the settling of heavy products.

De préférence, cette cuve comporte à sa partie supérieure un système de réglettes amovibles, ce qui permet le réglage de la séparation des produits en augmentant ou en diminuant le niveau libre du liquide utilisé.Preferably, this tank has in its part a system of removable strips, which allows the adjustment of the separation of the products by increasing or decreasing the free level of the liquid used.

La description qui va suivre, et qui ne présente aucun caractère limitatif, doit être lue en regard des figures annexées, parmi lesquelles :

  • - la figure 1 représente une vue en élévation d'un séparateur hydraulique selon la présente invention ;
  • - la figure 2 est une vue en coupe d'un tel séparateur selon la ligne AA de la figure 1 ;
  • - la figure 3 est une vue en coupe transversale de ce séparateur selon la ligne BB de la figure 2.
The description which follows, and which is in no way limiting, must be read with reference to the appended figures, among which:
  • - Figure 1 shows an elevational view of a hydraulic separator according to the present invention;
  • - Figure 2 is a sectional view of such a separator along the line AA of Figure 1;
  • FIG. 3 is a cross-sectional view of this separator along the line BB in FIG. 2.

Ainsi qu'on peut le voir sur la figure 1, un séparateur hydraulique selon la présente invention référencé 1 dans son ensemble est monté sur un bâti 2.As can be seen in FIG. 1, a hydraulic separator according to the present invention referenced 1 as a whole is mounted on a frame 2.

Ce séparateur hydraulique 1 est constitué par une cuve 3 de section transversale rectangulaire, de largeur constante et dont la section verticale est un trapèze rectangle. La grande base de celui-ci correspond à la partie haute 4 de cette cuve 3.This hydraulic separator 1 is constituted by a tank 3 of rectangular cross section, of constant width and whose vertical section is a rectangular trapezoid. The large base thereof corresponds to the upper part 4 of this tank 3.

La cuve 3 comporte, d'une part, un déversoir 5 qui est situé à l'extrémité de son côté incliné 6 et, d'autre part, une arrivée 7 sous pression de liquide tel que l'eau.The tank 3 comprises, on the one hand, a weir 5 which is located at the end of its inclined side 6 and, on the other hand, an inlet 7 under pressure of liquid such as water.

Une cheminée 8 qui est un parallélépipède à section carrée est disposée dans la cuve 3. Elle est prolongée à sa partie supérieure, qui est située au-dessous du niveau du bord supérieur de cette cuve 3, par une goulotte 9 pour évacuer les éléments légers. A l'opposé de cette goulotte 9 est disposé un canal 10 (figure 2) qui est légèrement incliné par rapport à l'horizontale par lequel les produits à classer sont introduits dans la cheminée 8.A chimney 8 which is a rectangular parallelepiped is placed in the tank 3. It is extended at its upper part, which is located below the level of the upper edge of this tank 3, by a chute 9 to evacuate the light elements . Opposite this chute 9 is a channel 10 (FIG. 2) which is slightly inclined relative to the horizontal by which the products to be classified are introduced into the chimney 8.

Le séparateur hydraulique 1 comprend un système de récupération pour les éléments lourds qui, selon ce mode de réalisation, est constitué par une chaîne à raclettes 11 qui est montée sur trois rouleaux : le rouleau 12 qui est situé au-dessus de la petite base 13 de la cuve 3, le rouleau 14 qui est disposé au-dessus du déversoir 5 et qui, dans ce mode de réalisation, entraîne la chaîne à raclettes 11, et le rouleau 15 étant monté à la verticale du rouleau 12 et dans le même plan horizontal que le rouleau 14. Ce rouleau 15 assure le réglage de la tension de la chaîne à raclettes 11.The hydraulic separator 1 comprises a recovery system for heavy elements which, according to this embodiment, consists of a squeegee chain 11 which is mounted on three rollers: the roller 12 which is located above the small base 13 of the tank 3, the roller 14 which is arranged above the weir 5 and which, in this embodiment, drives the squeegee chain 11, and the roller 15 being mounted vertically on the roller 12 and in the same horizontal plane as the roller 14. This roller 15 ensures the adjustment of the chain tension raclette 11.

Selon cet exemple, la cuve comporte un déflecteur 16 situé sous la cheminée 8 et au-dessus du rouleau 14, ainsi que, comme représenté sur la figure 3, deux bavettes 17 et 18 fixées le long des deux faces 19 et 20 de la cuve 3 de telle sorte que les éléments lourds s'accumulent et restent sur le trajet des raclettes.According to this example, the tank has a deflector 16 located under the chimney 8 and above the roller 14, as well as, as shown in FIG. 3, two flaps 17 and 18 fixed along the two faces 19 and 20 of the tank 3 so that the heavy elements accumulate and remain in the path of the squeegees.

Le dispositif 7 pour injecter un liquide est, dans cet exemple, situé sur le côté opposé au plan incliné au niveau de la cheminée 8 de telle sorte que l'arrivée du liquide ne gêne pas la décantation des produits lourds.The device 7 for injecting a liquid is, in this example, located on the side opposite the inclined plane at the level of the chimney 8 so that the arrival of the liquid does not interfere with the settling of heavy products.

Enfin, la cuve 3 est munie à sa partie supérieure, par exemple sur sa face 19, d'un système 21 de réglettes amovibles : ceci permet le réglage de la séparation des produits en augmentant ou en diminuant le niveau libre du liquide utilisé.Finally, the tank 3 is provided at its upper part, for example on its face 19, with a system 21 of removable strips: this allows the adjustment of the separation of the products by increasing or decreasing the free level of the liquid used.

Le principe de fonctionnement du séparateur hydraulique 1 consiste à annuler ou inverser, à la partie supérieure de la cheminée 8, l'action des forces dues à la pesanteur sur les produits à éliminer.The operating principle of the hydraulic separator 1 consists in canceling or reversing, at the top of the chimney 8, the action of the forces due to gravity on the products to be eliminated.

Pour cela les produits à classer sont introduits dans la cheminée 8 par le canal 10 de façon tangentielle à la surface du liquide, donc avec une vitesse dont la composante verticale est pour ainsi dire nulle. Ces produits reçoivent de la part du courant d'eau ascendant dans la cheminée 8 une poussée égale au poids des éléments de densité de séparation choisie.For this, the products to be classified are introduced into the stack 8 through the channel 10 tangentially to the surface of the liquid, therefore with a speed whose vertical component is almost zero. These products receive from the rising water stream in the chimney 8 a thrust equal to the weight of the elements of selected separation density.

Ainsi les éléments légers flottent à la surface du liquide dans la cheminée 8 et sont entraînés par lui dans la goulotte 9 d'évacuation. Par contre les éléments lourds tombent au fond de la cuve 3 où ils sont remontés jusqu'au déversoir 5 par la chaîne à raclettes 11.Thus the light elements float on the surface of the liquid in the chimney 8 and are entrained by it in the discharge chute 9. On the other hand, the heavy elements fall to the bottom of the tank 3 where they are raised to the weir 5 by the squeegee chain 11.

Le système 21 de réglettes amovibles permet de fixer le niveau de débordement du liquide et par là-même de contrôler la vitesse ascendante de ce liquide dans la cheminée 8 : plus le niveau de débordement est proche du bord supérieur de la cuve 3, plus la vitesse ascendante du liquide est élevée.The system 21 of removable strips makes it possible to fix the level of overflow of the liquid and thereby to control the upward speed of this liquid in the stack 8: the closer the overflow level is to the upper edge of the tank 3, the higher the upward speed of the liquid.

L'homme de métier saura apprécier les avantages d'un tel séparateur hydraulique. Notamment on notera son fonctionnement simple et sûr puisque, d'une part, le liquide utilisé, l'eau généralement, n'a besoin d'aucun traitement particulier et peut être recyclée après un passage éventuel sur un tamis, et, d'autre part, il n'y a pas besoin d'intervenir après avoir réglé le niveau d'eau dans la cuve. En outre, il y a lieu de signaler que les séparations réalisées ne dépendent pratiquement pas de la dimension des produits à traiter ni de leur débit qui peut varier sur une grande échelle.Those skilled in the art will appreciate the advantages of such a hydraulic separator. In particular, note its simple and safe operation since, on the one hand, the liquid used, water generally, does not need any particular treatment and can be recycled after a possible passage over a sieve, and, on the other hand apart, there is no need to intervene after adjusting the water level in the tank. In addition, it should be noted that the separations carried out practically do not depend on the size of the products to be treated or on their flow rate which can vary on a large scale.
