Abstract

The device for emptying bulk materials from a lorry comprises flexible sheets (1) attached to its walls. These can be compressed by air, oil or water fed into the spaces (A, B) between the walls (2) of the lorry and the sheets

Description

La présente invention concerne un dispositif permettant optimiser le volume utile (C) de stockage de produits en vrac, en particulier dans les camions, remorques et semi-remorques ou wagons transportant des aliments pour le bétail. Par extension, elle est applicable au stockage de tout produit nécessitant des pentes pour assurer l'écoulement de ceux-ci. The present invention relates to a device for optimizing the useful volume (C) for storing bulk products, in particular in trucks, trailers and semi-trailers or wagons transporting animal feed. By extension, it is applicable to the storage of any product requiring slopes to ensure their flow.

En général les citernes sont fabriquées avec un fond en forme d'entonnoir pour que le contenu descende naturellement vers un transporteur (3) (voir figure 3). In general, tanks are manufactured with a funnel-shaped bottom so that the content naturally descends towards a conveyor (3) (see Figure 3).

Le dispositif selon l'invention permet de remédier à cet inconvénient, et donc, d'utiliser la totalité du volume disponible qui sont souvent limités sur des ensembles mobiles. The device according to the invention makes it possible to remedy this drawback, and therefore to use the entire available volume which are often limited on mobile assemblies.

Le dispositif selon la présente invention, destiné à faire varier et notamment à augmenter le volume utile de stockage (C) de produits en vrac, comprend une paroi souple (1) fixée à l'intérieur de la paroi rigide (2) et formant avec celle-ci au moins une poche étanche (B), déformable permettant de recréer les pentes nécessaires à l'écoulement du contenu en modifiant volume utile de stockage. The device according to the present invention, intended to vary and in particular to increase the useful storage volume (C) of bulk products, comprises a flexible wall (1) fixed inside the rigid wall (2) and forming with this at least one waterproof pocket (B), deformable making it possible to recreate the slopes necessary for the flow of the content by modifying the useful storage volume.

Selon un mode particulier de réalisation le dispositif comprend deux poches souples (B) fixées à l'intérieur des parois rigides encadrant le transporteur (3). According to a particular embodiment, the device comprises two flexible pockets (B) fixed inside the rigid walls framing the conveyor (3).

La déformation étant assurée par leur gonflement en utilisant de l'air comprimée fournie par une source d'énergie quelconque. The deformation is ensured by their swelling using compressed air supplied by any energy source.

Le gonflement est assuré dans un-mode particulier de réalisation par de l'eau, de l'huile ou d'autres disponibles sur le marché. The swelling is ensured in a particular embodiment by water, oil or others available on the market.

Les parois intérieures souples ne recouvrent pas nécessairement la totalité parois extérieurs. The flexible interior walls do not necessarily cover all of the exterior walls.

La citerne de forme cubique, parallélépipédique ou autre éventuellement (voir figures ]et 2), avec un système transporteur (3) situé sous, dans ou à coté de celle-ci (voir exemples figures 5 et 6). Le (ou les) transporteurs peuvent être isolés du chargement par des trappes de fermeture. Le fond et les parois sont doublés par une deuxième paroi souple (1), plaquée contre la première (2) par la charge et étanche sur toute la périphérie. The tank of cubic, parallelepiped or other form possibly (see figures] and 2), with a conveyor system (3) located under, in or next to it (see examples figures 5 and 6). The carrier (s) can be isolated from the load by closing hatches. The bottom and the walls are lined by a second flexible wall (1), pressed against the first (2) by the load and sealed over the entire periphery.

Lors du déchargement, les parois souples (1) sont mises en forme en utilisant l'air comprimé du camion ou tracteur ou toute autre source d'énergie. Pour ce faire il est évident les volumes A et B doivent être étanches entre les parois (1) et (2), avec une arrivee pour le gonflage et le dégonflage de ceux-ci. During unloading, the flexible walls (1) are shaped using compressed air from the truck or tractor or any other source of energy. To do this, it is obvious that volumes A and B must be sealed between the walls (1) and (2), with an inlet for inflating and deflating them.

Lors du chargement les volumes (A et B) sont mis à l'atmosphère, pendant l'écoulement des produits, les parois souples (1) se plaquent contre les parois rigides (2) et remplissent la totalité du volume disponible (éventuellement, la pression résiduelle dans les volumes A et B doit être calculée pour que le poids des produits utilisés soit supérieur à la force exercée par la surface des parois souples). Pour le déchargement, l'écoulement vers les transporteurs (3) se fait naturellement pour le volume C. Lorsque la masse disponible dans la citerne diminue, de l'air comprimé est injecté (manuellement ou automatiquement) dans les volumes A et B. La pression doit être suffisante, soit par régulation manuelle soit par régulation calculée en fonction de la densité du produit, pour gonfler ces volumes et repousser les produits dans le (ou les) transporteurs (3). When loading the volumes (A and B) are put into the atmosphere, during the flow of the products, the flexible walls (1) are pressed against the rigid walls (2) and fill the entire available volume (possibly, the residual pressure in volumes A and B must be calculated so that the weight of the products used is greater than the force exerted by the surface of the flexible walls). For unloading, the flow to the conveyors (3) takes place naturally for volume C. When the mass available in the tank decreases, compressed air is injected (manually or automatically) in volumes A and B. The pressure must be sufficient, either by manual regulation or by regulation calculated according to the density of the product, to inflate these volumes and repel the products in the (or) conveyors (3).

Le mouvement parois souple permet, en fonction de la pression exercée par la charge, modifier les pentes et donc de casser toutes formes de talus ou de dôme qui peuvent éventuellement limiter, voire bloquer, l'écoulement du produit. The flexible wall movement allows, depending on the pressure exerted by the load, to modify the slopes and therefore to break all forms of slope or dome which can possibly limit, even block, the flow of the product.

A volume égal, centre de gravité est situé plus bas sur le dispositif proposé que sur citernes conventionnelles. Celui-ci permet donc d'améliorer la tenue de route pour le transport routier. At equal volume, center of gravity is located lower on the proposed device than on conventional tanks. This therefore improves road handling for road transport.

Le fait d'avoir parois souples et mobiles permet d'améliorer le nettoyage des citernes donc de permettre meilleur contrôle du nettoyage. The fact of having flexible and movable walls makes it possible to improve the cleaning of the tanks therefore allowing better control of the cleaning.

Les dessins annexés illustrent l'invention La figure 1 représente, en coupe, vue arrière, le dispositif de l'invention pendant le chargement du produit. The accompanying drawings illustrate the invention. FIG. 1 represents, in section, rear view, the device of the invention during the loading of the product.

La figure 3 represente, sur des ensembles routiers, les volumes moyens (D) des citernes régulièrement utilisées à ce jour avec mention des volumes moyens, par mètre linéaire. Exemple : le volume D, pour une hauteur (4) de 2,9 mètres et une largeur (5) de 2,55 mètres, est d'environ 5,5 par mètre linéaire. Figure 3 shows, on road combinations, the average volumes (D) of the tanks regularly used to date with mention of the average volumes, per linear meter. Example: volume D, for a height (4) of 2.9 meters and a width (5) of 2.55 meters, is approximately 5.5 per linear meter.

La figure 4 représente, sur les mêmes ensembles que ceux de la figure 3, les volumes moyens (E) que l'on peut obtenir en utilisant le dispositif de l'invention. Exemple : le volume E, pour une hauteur (4) 2,9 mètres et une largeur (5) de 2,55 mètres, est d'environ 7,4 m3 par mètre linéaire. Figure 4 shows, on the same sets as those of Figure 3, the average volumes (E) that can be obtained using the device of the invention. Example: volume E, for a height (4) 2.9 meters and a width (5) of 2.55 meters, is approximately 7.4 m3 per linear meter.

Les figures (5) et (6) représentent, pour exemple, deux versions de positionnement des transporteurs qui ne sont possible qu'avec le dispositif de l'invention.Figures (5) and (6) show, for example, two versions of positioning of the carriers which are only possible with the device of the invention.
