ENCEINTE DE STOCKAGE TEMPORAIRE DE PRODUITS DU TYPE GRANULEUX
L'invention se rapporte à une enceinte de stockage temporaire de produits du type granuleux tels des céréales. TEMPORARY STORAGE ENCLOSURE OF GRANULAR PRODUCTS
The invention relates to a temporary storage enclosure for products of the granular type such as cereals.
L'invention n'est bien entendu pas strictement limitée à ce type de produits granuleux. The invention is of course not strictly limited to this type of granular products.
Pour le stockage des céréales, on utilise communément des structures en béton ou en métal ayant une forme globalement cylindrique de révolution et d'axe vertical. For the storage of cereals, concrete or metal structures are commonly used having a generally cylindrical shape of revolution and a vertical axis.
Lors de la période de récolte, il n'est pas rare que localement les enceintes de stockage utilisables pour la collecte de la récolte de la région soient momentanément insuffisantes. During the harvest period, it is not uncommon that locally the storage enclosures usable for collecting the harvest of the region are temporarily insufficient.
Il est alors nécessaire d'entreposer provisoirement, par exemple, pendant quinze jours, la récolte sur un plan en béton généralement non couvert. It is then necessary to temporarily store, for example, for fifteen days, the harvest on a concrete surface generally not covered.
Pour contenir les produits, autour de la surface d'entreposage sont alors posés des éléments préfabriqués qui vont délimiter une paroi latérale qui va permettre de réaliser un tas relativement haut. To contain the products, around the storage surface are then placed prefabricated elements which will delimit a side wall which will allow a relatively high pile to be produced.
La durée de ce stockage temporaire doit être la plus courte possible notamment en raison des risques d'intempéries et de la chaleur qui potentiellement peut se dégager de cette masse. The duration of this temporary storage must be as short as possible, in particular because of the risk of bad weather and the heat which potentially can be released from this mass.
En effet, les graines sont plus ou moins humides et le stockage de celle ci peut induire un échauffement. Indeed, the seeds are more or less humid and the storage of this one can induce a heating.
Dans les enceintes classiques, des moyens sont prévus pour assurer une ventilation de la récolte mais tel n'est pas le cas pour ces stockages temporaires. In conventional enclosures, means are provided to ensure ventilation of the crop, but this is not the case for these temporary storage.
Parfois, pour réduire ce risque d'échauffement, sur ce type de stockage temporaire, on déplace simplement la masse de graines avec des pelleteuses ce qui nécessite de disposer d'un espace assez important. Sometimes, to reduce this risk of overheating, on this type of temporary storage, we simply move the mass of seeds with backhoes which requires having a fairly large space.
En cas de durée plus longue ou de risque d'averse, il arrive parfois que l'on pose au dessus du tas de céréales, une bâche qui, en théorie, devrait limiter la pénétration de l'eau mais celle-ci ne peut être installée qu'au dernier moment car cela entraînerait une augmentation de la chaleur des céréales stockées. In case of longer duration or risk of downpours, it sometimes happens that a tarpaulin is placed above the heap of cereals which, in theory, should limit the penetration of water but this cannot be installed only at the last moment as this would cause an increase in the heat of the stored cereals.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
L'invention se propose de remédier à cet inconvénient et, à cet effet, l'invention a pour objet une enceinte de stockage temporaire définie par un fond et une paroi latérale contenant une masse d'un produit notamment granuleux,
cette enceinte étant caractérisé en ce que : - le fond est équipé de moyens de diffusion d'air, - le haut de l'enceinte est fermé par une bâche comportant des manches à air débouchant à l'extérieur du volume délimité par le fond, la paroi latérale et la dite bâche de sorte que l'air circule de bas en haut et s'échappe par les manches à air. The invention proposes to remedy this drawback and, for this purpose, the invention relates to a temporary storage enclosure defined by a bottom and a side wall containing a mass of a product, in particular a granular product,
this enclosure being characterized in that: - the bottom is equipped with air diffusion means, - the top of the enclosure is closed by a cover comprising air sleeves opening to the outside of the volume delimited by the bottom, the side wall and said tarpaulin so that the air circulates from bottom to top and escapes through the air bags.
L'invention sera bien comprise à la lecture de la description ci-après faite à titre d'exemple non limitatif en regard du dessin qui représente schématiquement : - figure 1 : vue d'un silo en coupe, - figure 2 : en plus gros plan, une partie de la figure 1, - figures 3 et 4 : deux détails du silo. The invention will be clearly understood on reading the description below made by way of nonlimiting example with regard to the drawing which schematically represents: - Figure 1: view of a silo in section, - Figure 2: in larger plan, part of figure 1, - figures 3 and 4: two details of the silo.
En se reportant au dessin, on voit une enceinte 1 de stockage temporaire qui, par exemple, peut être utilisée pour des céréales. Referring to the drawing, we see an enclosure 1 for temporary storage which, for example, can be used for cereals.
Cette enceinte 1 temporaire définie par un fond 2 et une paroi 4 latérale contient donc une masse 5 d'un produit notamment granuleux. This temporary enclosure 1 defined by a bottom 2 and a side wall 4 therefore contains a mass 5 of a product in particular granular.
Lorsque cette enceinte est remplie, il se forme habituellement un dôme en sa partie centrale qui se situe à un niveau supérieur à celui du bord supérieur de l'enceinte. When this enclosure is filled, a dome is usually formed in its central part which is situated at a level higher than that of the upper edge of the enclosure.
Le remplissage est par exemple réalisé par un dispositif couramment appelé une sauterelle. The filling is for example carried out by a device commonly called a grasshopper.
Selon l'invention : - le fond 2 est équipé de moyens 6 de diffusion d'air, et - le haut de l'enceinte est fermé par une bâche 7 comportant des manches 8 à air débouchant à l'extérieur du volume délimité par le fond, la paroi latérale et la dite bâche de sorte que l'air circule de bas en haut et s'échappe par les manches 8 à air. According to the invention: - the bottom 2 is equipped with means 6 for air diffusion, and - the top of the enclosure is closed by a cover 7 comprising air sleeves 8 opening out of the volume delimited by the bottom, side wall and said tarpaulin so that the air circulates from bottom to top and escapes through the air sleeves 8.
La dimension de la bâche et les points d'ancrage de celle-ci sur sa périphérie sont déterminés pour préserver, entre le haut de la masse de produit The size of the sheet and the anchoring points thereof on its periphery are determined to preserve, between the top of the mass of product
<Desc/Clms Page number 3><Desc / Clms Page number 3>
contenu dans l'enceinte et la face inférieure de la bâche, un léger espace 9 pour que l'air provenant des moyens de diffusion puisse circuler au travers du produit et au dessus du tas pour atteindre les manches à air. contained in the enclosure and the underside of the sheet, a slight space 9 so that the air coming from the diffusion means can circulate through the product and above the pile to reach the air sleeves.
La bâche est soulevée légèrement du haut du tas du fait de l'air soufflé. The tarpaulin is lifted slightly from the top of the pile due to the blown air.
Il se forme alors entre la bâche et le tas, un espace dans lequel circule l'air. It then forms between the sheet and the heap, a space in which the air circulates.
Les manches 8 à air sont des cheminées 8 qui permettent d'évacuer l'air vers l'extérieur. The air vents 8 are chimneys 8 which allow the air to be discharged to the outside.
Le débit d'air au niveau de ces manchettes 8 peut être réglé. The air flow at these cuffs 8 can be adjusted.
A cet effet, les manches à air sont équipés de moyens 10 de réglage du débit. To this end, the air bags are equipped with means 10 for adjusting the flow rate.
Ces moyens 10 de réglage consistent par exemple en un moyen de modification de la section de passage de ces manchettes. These adjustment means 10 consist, for example, of a means for modifying the passage section of these cuffs.
Par exemple, un lien 10 réalise ce moyen de réglage de la section. For example, a link 10 achieves this means of adjusting the section.
Les moyens 6 de diffusion d'air sont réalisés par des tubes 6A posés sur le sol, reliés à une alimentation en air telle un compresseur (non représenté). The air diffusion means 6 are produced by tubes 6A placed on the ground, connected to an air supply such as a compressor (not shown).
Ces tubes 6A sont pourvus de perçages 6B ou ajutages permettant de diffuser l'air vers le haut et latéralement. These tubes 6A are provided with holes 6B or nozzles making it possible to diffuse the air upwards and laterally.
Pour la fixation de la bâche, celle-ci est équipée sur la face externe de sangles 11. For fixing the cover, the cover is fitted on the external face with straps 11.
Ces sangles sont, à l'exception des extrémités, fixées sur la face externe de la bâche de sorte quelle en sont solidaires de la bâche. These straps are, with the exception of the ends, fixed to the external face of the sheet so that they are integral with the sheet.
De préférence, ces sangles s'étendent entre les bords opposés de la bâche lorsque celle-ci est carrée ou rectangulaire. Preferably, these straps extend between the opposite edges of the sheet when the latter is square or rectangular.
Dans le cas d'une bâche circulaire, les sangles sont alors disposées radialement. In the case of a circular sheet, the straps are then arranged radially.
Lorsque la bâche est de taille inférieure à la surface à recouvrir, on utilise plusieurs bâches avec un recouvrement partiel. When the cover is smaller than the surface to be covered, several covers are used with partial cover.
A cet effet, les bords des bâches devant se chevaucher sont équipés de tubes 12 de sorte qu'au niveau du chevauchement l'eau ne peut stagner. To this end, the edges of the tarpaulins which overlap are fitted with tubes 12 so that at the level of the overlap the water cannot stagnate.
La bâche comporte alors un ou plusieurs passants. The cover then has one or more passers-by.
La première bâche est posée pour être tendue. The first cover is placed to be stretched.
On pose ensuite la deuxième bâche en sorte que son bord soit en retrait du bord de la première bâche. The second cover is then placed so that its edge is set back from the edge of the first cover.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Les bâches sont alors associées entre elles au moyen des sangles qui les équipent. The sheets are then associated with each other by means of the straps which equip them.
Un accrochage du bord de la bâche sur les éléments préfabriqués termine la fixation. A hanging of the edge of the sheet on the prefabricated elements completes the fixing.
Des tendeurs 13 à rochet assureront la tension sur les sangles. Ratchet tensioners 13 will provide tension on the straps.
Outre les cheminées, la bâche pourra être équipée de regard permettant d'y insérer une sonde de prise de température. In addition to the chimneys, the tarpaulin can be fitted with a manhole allowing the insertion of a temperature sensor.
Un capot fermera le regard. A hood will close the eye.
On peut donc ainsi constituer des enceintes de stockage provisoire bénéficiant d'une ventilation et d'une protection contre la pluie. It is thus possible to constitute temporary storage enclosures benefiting from ventilation and protection against rain.
