Abstract

The present invention relates to a reservoir, for storing pulverulent or granular materials, with a flat base. According to the invention, an elastic membrane 3 is arranged in the lower part of the reservoir; when the reservoir is empty, this membrane delimits inclined surfaces which are connected to a recovery (take-up) transporter or to an opening 5 provided in the base 2 of the reservoir and form an angle with the horizontal which is at least equal to the natural slope angle of the product intended to be placed in this reservoir.

Description

La présente invention concerne des réservoirs de stockage de matières pulvérulentes ou granuleuses, qui sont soit fixes tels que les silos, soit mobiles tels que les bateaux, les péniches, les camions, les wagons ou autres engins de transport. The present invention relates to storage tanks for powdery or granular materials, which are either fixed such as silos, or mobile such as boats, barges, trucks, wagons or other transport vehicles.

Ces réservoirs peuvent comporter un fond en pente, ce qui permet une vidange facile. Cependant, le plus souvent, ils présentent un fond plat car, pour un même encombrement, le volume de stockage est plus grand. Mais il est alors difficile de vider complètement le réservoir, en particulier lorsqu'il contient un produit coulant mal. I1 reste dans le fond du réservoir un volume de produit dont la surface supérieure est en forme de tronc de cone ou de tronc de pyramide et fait avec l'horizontale un angle égal à l'angle de talus naturel du produit. These tanks may have a sloping bottom, which allows easy emptying. However, most often, they have a flat bottom because, for the same size, the storage volume is greater. However, it is then difficult to completely empty the tank, in particular when it contains a poorly flowing product. I1 remains in the bottom of the tank a volume of product whose upper surface is in the form of a cone trunk or pyramid trunk and makes with the horizontal an angle equal to the natural slope angle of the product.

La présente invention a pour objet un réservoir de stockage de matière pulvérulente ou granuleuse, à fond plat, qui peut, au contraire, être vidé complètement. The subject of the present invention is a storage tank for pulverulent or granular material, with a flat bottom, which can, on the contrary, be emptied completely.

Le réservoir selon l'invention est caractérisé en ce que, dans sa partie inférieure, est disposée une membrane élastique qui, lorsque le réservoir est vide, délimite des surfaces inclinées qui sont raccordées à un transporteur de reprise ou à une ouverture prévue dans le fond du réservoir et font avec l'horizontale un angle au moins égal à l'angle de talus naturel du produit destiné à être placé dans ce réservoir. The tank according to the invention is characterized in that, in its lower part, is arranged an elastic membrane which, when the tank is empty, delimits inclined surfaces which are connected to a return conveyor or to an opening provided in the bottom of the tank and make an angle with the horizontal at least equal to the natural slope angle of the product intended to be placed in this tank.

Lors du remplissage du réservoir, la membrane se déforme et finit par s'appliquer sur le fond plat de ce réservoir, ce qui permet de remplir complètement celui-ci. Lors de la vidange,la membrane reprend sa forme initiale, de sorte que le réservoir se vide complètement de manière gravitaire. When filling the tank, the membrane deforms and ends up applying to the flat bottom of this tank, which allows it to be completely filled. When emptying, the membrane returns to its original shape, so that the tank empties completely by gravity.

On a décrit ci-après,à titre d'exemple non limitatif, un mode de réalisation d'un silo réalisé selon l'invention, avec référence à la figure unique du dessin annexé qui est une vue en coupe verticale du silo. An embodiment of a silo produced according to the invention has been described below, by way of non-limiting example, with reference to the single figure of the appended drawing which is a view in vertical section of the silo.

Tel qu'il est représenté au dessin, le silo 1 comporte un fond plat 2; il peut avoir en plan une forme quelconque, par exemple circulaire ou carrée. Une membrane 3 en élastomère qui a une forme tronconique dans le cas d'un silo circulaire ou la forme d'un tronc de pyramide dans le cas d'un silo de section carrée, est fixée en 4 à la paroi du silo, à une certaine dis tance du fond 2, et au centre de ce fond, auquel est prévue une ouverture d'évacuation 5. L'angle que fait la membrane 3 avec le plan horizontal est supérieur à l'angle de talus naturel que doit contenir le silo. As shown in the drawing, the silo 1 has a flat bottom 2; it can have in plan any shape, for example circular or square. An elastomer membrane 3 which has a frustoconical shape in the case of a circular silo or the shape of a pyramid trunk in the case of a square section silo, is fixed at 4 to the wall of the silo, at a certain distance from the bottom 2, and at the center of this bottom, which is provided with an evacuation opening 5. The angle made by the membrane 3 with the horizontal plane is greater than the natural slope angle that the silo must contain .

Lorsqu'on remplit le silo, la membrane 3 se déforme et s'allonge sous l'effet du poids du produit, pour finir par s'appliquer sur le fond 2 du silo et sur la paroi latérale de celui-ci, comme représenté en traits mixtes au dessin. When the silo is filled, the membrane 3 deforms and elongates under the effect of the weight of the product, finally applying to the bottom 2 of the silo and to the side wall of the latter, as shown in mixed lines in the drawing.

Lors de la vidange, la membrane 3 revient à sa forme d'origine dès que la charge verticale du produit diminue en-dessous d'une certaine valeur. Le silo se vide ainsi complètement. When emptying, the membrane 3 returns to its original shape as soon as the vertical load of the product decreases below a certain value. The silo is thus emptied completely.

On peut éventuellement prévoir dans la paroi du silo 1, en dessous de la zone de fixation 4 de la membrane, une ouverture 6 dans laquelle est monté un ventilateur 7. Celui-ci engendre dans l'espace 8 existant entre le silo et la membrane une légère pression qui aide la membrane à reprendre sa forme initiale dans le cas de certains produits particulièrement lourds. One can optionally provide in the wall of the silo 1, below the fixing area 4 of the membrane, an opening 6 in which is mounted a fan 7. This generates in the space 8 existing between the silo and the membrane a slight pressure which helps the membrane to return to its initial shape in the case of certain particularly heavy products.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. C'est ainsi que, lorsque le réservoir a en plan une forme rectangulaire la membrane peut former deux plans inclinés raccordés à leur extrémité inférieure à un transporteur de reprise prévu dans le fond du réservoir.  It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof. Thus, when the tank has a rectangular shape in plan the membrane can form two inclined planes connected at their lower end to a recovery conveyor provided in the bottom of the tank.
