Description

La présente invention est relative à une grille pour rigole, plus particulièrement pour une rigole prévue au fond d'un magasin pour matière granuleuse, tel que du grain et analogue, dans laquelle de l'air ou un autre gaz doit être soufflé.The present invention relates to a grid for a channel, more particularly for a channel provided at the bottom of a store for granular material, such as grain and the like, into which air or another gas must be blown.

Les grilles utilisées jusqu'à présent pour couvrir de telles rigoles ou canaux sont en général composées soit de barreaux ou lattes sur lesquels est placé un treillis en fer ou alliage de cuivre, soit par une tôle métallique perforée, soudée à un encadrement métallique.The grids used until now to cover such channels or channels are generally composed either of bars or slats on which is placed an iron or copper alloy lattice, or by a perforated metal sheet, welded to a metal frame.

Une forme de réalisation aussi bien que l'autre offrent d'importants inconvénients.One embodiment as well as the other offer significant disadvantages.

En effet, de telles grilles ne sont en général par suffisamment solides pour permettre le passage sur elles des engins de manutention.Indeed, such grids are generally not strong enough to allow the passage of handling equipment over them.

En outre, l'utilisation de telles grilles a pour conséquence que les rigoles sur lesquelles elles sont placées doivent fréquemment être nettoyées. Il arrive toujours que de la poussière et de fines particules granuleuses traversent le grillage ou les trous de la tôle et bouchent partiellement les rigoles.In addition, the use of such grids has the consequence that the channels on which they are placed must frequently be cleaned. It always happens that dust and fine grainy particles pass through the screen or the holes of the sheet and partially block the channels.

L'invention a principalement pour but d'éliminer ces onconvénients grâce à une grille de construction très simple.The main object of the invention is to eliminate these disadvantages thanks to a very simple construction grid.

A cette fin, la grille suivant l'invention présente des éléments concaves qui se trouvent à une certaine distance horizontale les uns des autres, de telle sorte que des espaces soient formés entre ces éléments, et qui sont dirigés avec leur côté concave vers le haut, les espaces précités étant recouverts par des pièces de protection qui pénètrent dans le creux offert par les éléments concaves, de telle sorte qu'avec ces derniers soient formées des chicanes à travers lesquelles un courant gazeux soufflé dans la rigole ou le canal est soumis à une déviation à partir des espaces précités sur un angle d'au moins 90° par rapport à la verticale et s'élève hors de la rigole, les dimensions et l'allure de ces chicanes étant telles que pratiquement aucune matière granuleuse ne peut pénétrer sous l'influence de la pesanteur dans le sens opposé à ce courant gazeux, dans les espaces précités.To this end, the grid according to the invention has concave elements which are at a certain horizontal distance from each other, so that spaces are formed between these elements, and which are directed with their concave side upwards. , the aforementioned spaces being covered by protective parts which penetrate into the hollow offered by the concave elements, so that with the latter baffles are formed through which a gas current blown into the channel or the channel is subjected to a deviation from the aforementioned spaces at an angle of at least 90 ° relative to the vertical and rises out of the channel, the dimensions and the shape of these baffles being such that practically no granular material can penetrate under the influence of gravity in the opposite direction to this gas stream, in the aforementioned spaces.

Dans une forme de réalisation particulière de l'invention, les éléments concaves aussi bien que les pièces de couverture ou de protection sont constituées par des profilés droits qui s'étendent parallëLement entre eux suivant la direction transversale de la rigole ou du canal.In a particular embodiment of the invention, the concave elements as well as the covering or protective parts consist of straight sections which extend parallel to one another in the transverse direction of the channel or channel.

Dans une forme de réalisation plus particulière de l'invention, les pièces de couverture sont également formées par un second jeu d'éléments concaves, qui sont montés avec leur côté concave dirigés vers le bas, au-dessus du premier jeu précité d'éléments concaves, sur les espaces compris entre les éléments successifs de ce premier jeu, de telle sorte que les éléments du second jeu chevauchent les bords longitudinaux dirigés l'un vers l'autre de deux éléments adjacents du premier jeu, pour former des chicanes.In a more particular embodiment of the invention, the cover parts are also formed by a second set of concave elements, which are mounted with their concave side facing down, above the first aforementioned set concave elements, on the spaces between the successive elements of this first set, so that the elements of the second set overlap the longitudinal edges directed towards each other of two adjacent elements of the first set, to form baffles.

Dans une forme de réalisation préférée de l'invention, le premier jeu d'éléments concaves aussi bien que le second sont formés par des profilés en L dont les ailes font un angle approximativement de 45° avec un plan horizontal et l'angle dièdre déterminé par le premier jeu d'éléments est dirigé vers le haut et celui du second jeu vers le bas, de telle sorte que les ailes dirigées l'une vers l'autre de deux éléments adjacents du premier jeu s'étendent jusque dans l'angle dièdre d'un élément du second jeu qui se.trouve au-dessus de l'espace compris entre ces deux éléments adjacents, à une certaine distance des ailes de l'élément précité du second jeu.In a preferred embodiment of the invention, the first set of concave elements as well as the second are formed by L-shaped profiles whose wings make an angle of approximately 45 ° with a horizontal plane and the determined dihedral angle by the first set of elements is directed upwards and that of the second set downwards, so that the wings directed towards each other of two adjacent elements of the first set extend up to the corner dihedral of an element of the second set which is located above the space between these two adjacent elements, at a certain distance from the wings of the above-mentioned element of the second set.

L'invention concerne également un magasin pour matière granuleuse, plus particulièrement pour des céréales et analogues, dont le fond est doté de rigoles ou canaux pour l'amenée d'un courant d'air, et qui sont recouverts par des grilles telles que décrites précédemment.The invention also relates to a store for granular material, more particularly for cereals and the like, the bottom of which is provided with channels or channels for the supply of an air stream, and which are covered by grids as described. previously.

Lors de l'entreposage de céréales, telles que du blé et analogues, en grands tas dans des magasins, il est de très grande importance pour s'opposer à la pourriture des céréales, de les aérer régulièrement ou même en continu grace à un courant d'air qui est soufflé dans le tas à partir du dessous. Ce soufflage d'air a lieu en général par l'intermédiaire de rigoles ou canaux qui sont répartis à des écartements réguliers sur le plancher du magasin et qui sont recouverts grace à une grille ou élément analogue, afin d'éviter que des grains de céréales ne tombent dans les rigoles et donc les bouchent.When storing cereals, such as wheat and the like, in large heaps in stores, it is of great importance to prevent rot of cereals, to aerate them regularly or even continuously with a current air that is blown into the pile from below. This blowing of air generally takes place through channels or channels which are distributed at regular intervals on the store floor and which are covered by a grid or the like, in order to prevent grains of cereals do not fall into the channels and therefore block them.

A la figure 1, on a illustré une telle installation de distribution d'air. Elle comprend une série de cylindres verticaux 1 qui sont dotés à leur partie supérieure d'un ventilateur 2 et sont raccordés à la partie inférieure à un réseau de distribution composé de rigoles ou canaux 3. Ceux-ci sont encastrés dans le sol 4 du magasin et sont couverts par des parties de grille successives 5 se raccordant les unes aux autres.In Figure 1, there is illustrated such an air distribution installation. It comprises a series of vertical cylinders 1 which are provided at their upper part with a fan 2 and are connected to the lower part to a distribution network composed of channels or channels 3. These are embedded in the ground 4 of the store and are covered by successive grid parts 5 connecting to each other.

La section transversale de ces rigoles se réduit graduellement à partir de la base du cylindre, auquel elles sont raccordées, afin d'obtenir un courant d'air 8 aussi uniforme que possible à travers les rigoles et par conséquent à travers la masse de grains 7.The cross section of these channels gradually decreases from the base of the cylinder, to which they are connected, in order to obtain an air stream 8 as uniform as possible through the channels and therefore through the mass of grains 7 .

Les cylindres 1 aussi bien que les grilles 3 sont de préférences formés de pièces préfabriquées en béton ou en matière synthétique.The cylinders 1 as well as the grids 3 are preferably formed from prefabricated parts made of concrete or synthetic material.

Les cylindres 1 à travers lesquels l'air est aspiré, forment simultanément les colonnes portantes de la charpente de toiture 6 du magasin (voir la figure 2).The cylinders 1 through which the air is sucked, simultaneously form the supporting columns of the roof structure 6 of the store (see FIG. 2).

Suivant l'invention, les parties de grille 5, qui forment un élément important de tels magasins, sont constituées par un jeu d'éléments concaves 9, qui se trouvent à une certaine distance horizontales les uns des autres, de telle sorte que des espaces 10 soient formés entre ces éléments 9, et qui sont dirigés avec leur côté concave vers le haut.According to the invention, the grid parts 5, which form an important element of such stores, are constituted by a set of concave elements 9, which are at a certain horizontal distance from each other, so that spaces 10 are formed between these elements 9, and which are directed with their concave side up.

Ces espaces 10 sont recouverts par des pièces de protection ou de couverture 11 qui.pénètrent partiellement dans l'espace creux 12 des éléments 9, de telle sorte qu'avec ces derniers soient formées des chicanes 13 à travers lesquelles un courant d'air soufflé dans les rigoles est soumis à une déviation à partir des espaces 10 sur un angle d'au moins 90° par rapport à la verticale, et s'élève hors des rigoles comme indiqué par une flèche 14 (figure 3).These spaces 10 are covered by protective or covering pieces 11 which . partially penetrate into the hollow space 12 of the elements 9, so that with the latter baffles 13 are formed through which a flow of air blown into the channels is deflected from the spaces 10 at an angle of at least 90 ° to the vertical, and rises out of the channels as indicated by an arrow 14 (Figure 3) .

Les dimensions et l'allure de ces chicanes 13 doivent être telles que pratiquement aucun grain de céréale 7 ne puisse pénétrer sous l'influence de la pesanteur dans l'espace 10 précité, suivant une direction opposée à celle de la flèche 14.The dimensions and the shape of these baffles 13 must be such that practically no grain of cereal 7 can penetrate under the influence of gravity into the space 1 0 above, in a direction opposite to that of the arrow 14.

Dans la forme de réalisation illustrée , plus particulièrement aux figures 3 et 4, les éléments concaves 9 aussi bien que les pièces de couverture 11 sont constitués par des profilés en L rectilignes qui s'étendent parallèlement entre eux suivant la direction transversale des rigoles 3.In the illustrated embodiment, more particularly in FIGS. 3 and 4, the concave elements 9 as well as the cover parts 11 are constituted by straight L-shaped profiles which extend parallel to each other in the transverse direction of the channels 3.

Ainsi, les pièces de couverture 11 sont également formées par un second jeu d'éléments concaves dirigés avec leur côté concave vers le bas, au-dessus de la première série précitée d'éléments concaves 9 et en face des espaces 10, de telle sorte qu'un élément 11 du second jeu chevauche les bords longitudinaux 15 dirigés l'un vers l'autre de deux éléments 9 adjacents du premier jeu, pour former les chicanes 13 précitées.Thus, the cover pieces 11 are also formed by a second set of concave elements directed with their concave side down, above the aforementioned first series of concave elements 9 and opposite the spaces 10, so that that an element 11 of the second set overlaps the longitudinal edges 15 directed towards each other of two adjacent elements 9 of the first set, to form the baffles 13 mentioned above.

Les ailes 16 et 17 des profilés en L 9 ainsi que les ailes 18 et 19 des profilés en L 11 forment un angle alpha d'approximativement 45° avec un plan horizontal.The wings 16 and 17 of the L-shaped profiles 9 as well as the wings 18 and 19 of the L-shaped profiles 11 form an alpha angle of approximately 45 ° with a horizontal plane.

Comme déjà indiqué ci-dessus, l'angle dièdre déterminé par les profilés en L 9, est dirigé vers le haut, tandis que celui des profilés 11 est dirigé vers le bas, de telle sorte que les ailes 16 et 17, dirigées l'une vers l'autre, de deux profilés 9 adjacents s'étendent jusque dans l'angle dièdre d'un profilé en L 11 qui se trouve au-dessus de l'espace 10 entre ces deux profilés en L 9 adjacents, à une distance déterminée des ailes 18 et 19 du profilé 11 précité, de telle sorte donc que les ailes 17 soient parallèles aux ailes 18 et les ailes 16 parallèles aux ailes 19. DE sommets 20, formant nervures, des angles dièdres des profilés en L 11 aussi bien que les sommets ou nervures 21 des profilés 9 sont situés dans un même plan. Sur ces nervures peuvent se déplacer les véhicules à l'aide desquels la matière granuleuse est manipulée dans le magasin, sans qu'il existe un danger que des grains situés sur la grille soient écrasés. Ces grains se trouvent toujours entre les nervures précitées.As already indicated above, the angle dihedral determined by the L-shaped profiles 9, is directed upwards, while that of the profiles 11 is directed downwards, so that the wings 16 and 17, directed towards each other, of two profiles 9 adjacent extend into the dihedral angle of an L-shaped profile 11 which is located above the space 10 between these two adjacent L-shaped profiles 9, at a determined distance from the wings 18 and 19 of the profile 11 cited above, so that the wings 17 are parallel to the wings 18 and the wings 16 parallel to the wings 19. DE vertices 20, forming ribs, dihedral angles of the L- shaped profiles 11 as well as the vertices or ribs 21 of the profiles 9 are located in the same plane. On these ribs can move vehicles with the help of which the grainy material is handled in the magazine, without there being a danger that grains located on the grid are crushed. These grains are always found between the aforementioned ribs.

Dans la forme de réalisation particulière illustrée aux figures, les profilés en L 9 et 11 sont formés par des fers cornières dont les extrémités sont montées sur deux profilés de support opposés 22 et 23, qui reposent dans le bord de la rigole 3, qui est dotée d'un profilé en L 24 ancré dans le plancher 4 du magasin, au moyen de fers d'ancrage 25. Ainsi qu'il ressort de la figure 3, les fers profilés 11 ont une réalisation plus lourde que celle des fers profilés 9, afin de donner à la grille une capacité portante suffisante et ainsi de résister au poids des engins de manutention.In the particular embodiment illustrated in the figures, the L-shaped profiles 9 and 11 are formed by angle irons, the ends of which are mounted on two opposite support profiles 22 and 23, which rest in the edge of the channel 3, which is endowed with an L-shaped profile 24 anchored in the floor 4 of the store, by means of anchoring irons 25. As it emerges from FIG. 3, the profiled irons 11 have a heavier realization than that of the profiled irons 9 , in order to give the grid sufficient bearing capacity and thus to resist the weight of handling equipment.

Comme indiqué précédemment, une grille est constituée par plusieurs parties de grille 5 successives et se raccordant librement les unes aux autres. Afin de former un passage continu entre ces parties de grille se raccordant l'une à l'autre, l'aile 19' du profilé en L 11' qui se trouve à une extrémité de la partie de grille fait saillie latéralement par rapport aux profilés porteurs 22 et 23 de cette partie,de telle sorte que cette aile en saillie 19' puisse coopérer avec le profilé en L 9' qui se trouve à l'autre extrémité de la partie de grille adjacente, pour former une chicane.As indicated above, a grid is formed by several successive grid parts 5 and freely connecting to each other. In order to form a continuous passage between these grid parts connecting to each other, the wing 19 'of the L-profile 11' which is at one end of the grid part protrudes laterally with respect to the profiles. carriers 22 and 23 of this part, so that this projecting wing 19 'can cooperate with the L- shaped section 9' which is at the other end of the adjacent grid part, to form a baffle.

Il est évident qu'inversément, l'aile correspondante 16' du profilé en L 9' pourrait éventuellement faire saillie afin de coopérer avec un gofilé en L 11', ne faisant pas saillie, d'une partie de grille limitrophe.It is obvious that, conversely, the corresponding wing 16 ′ of the L-shaped profile 9 ′ could possibly protrude in order to cooperate with an L-shaped profile 11 ′, not protruding, from a part of the bordering grid.

Il doit être entendu que la présente invention n'est en acune façon limitée aux formes de réalisation ci-avant et que bien ces modifications peuvent y être apportées sans sortir du cadre du présent brevet.It should be understood that the present invention is in no way limited to the above embodiments and that indeed these modifications can be made without departing from the scope of this patent.

Ceci concerne en particulier la forme des éléments concaves, qui pourraient par exemple être constitués par des demi- cylindres.This concerns in particular the shape of the concave elements, which could for example consist of half-cylinders.

De même, l'utilisation de la grille 5 n'est pas limitée à des rigoles ou canaux dans des magasins pour céréales, mais elle peut par exemple être mise en oeuvre dans des domaines très divers où apparaissent des problèmes quelque peu analogues.Similarly, the use of the grid 5 is not limited to channels or channels in cereal stores, but it can for example be implemented in very diverse fields where somewhat similar problems appear.

Pour la simplification, les profilés en L 9 et 11 pourraient ètre identiques.For simplification, the profiles in L 9 and 11 could be identical.
