Description
L'invention concerne un dispositif de séchage d'un produit en céramique, notamment en argile.The invention relates to a device for drying a ceramic product, especially clay.
Lors de la fabrication de produit en argile tels que des briques, ces dernières sont successivement extrudées, séchées, cuites et éventuellement rectifiées.During the manufacture of clay products such as bricks, the latter are successively extruded, dried, cooked and optionally ground.
Lors de l'opération de séchage, les produits sont classiquement disposés sur des grilles. De l'air chaud passant au travers des grilles est amené sur toute la surface des produits afin d'assurer un séchage uniforme de ceux-ci.During the drying operation, the products are conventionally arranged on grids. Hot air passing through the grids is brought over the entire surface of the products to ensure uniform drying thereof.
Lors de cette opération de séchage, les produits sont soumis à un phénomène de rétraction au cours duquel leurs dimensions sont sensiblement réduites.During this drying operation, the products are subjected to a retraction phenomenon in which their dimensions are substantially reduced.
Du fait de la malléabilité du matériau dans sa forme non séchée et sous l'effet de leur poids, les produits s'enfoncent légèrement dans les grilles et s'ancrent dans celles-ci.Because of the malleability of the material in its undried form and under the effect of their weight, the products sink slightly into the grids and are anchored in them.
Ainsi, lors du séchage et du retrait dimensionnel des produits, des tensions s'appliquent au niveau des zones d'ancrage. Ces tensions génèrent des déformations ou des fissurations des produits.Thus, during the drying and the dimensional shrinkage of the products, tensions apply at the level of the anchoring zones. These tensions generate deformations or cracks in the products.
Afin de remédier à cet inconvénient, le document
De cette manière, lors de la rétraction des produits durant le séchage, les rouleaux pivotent progressivement dans les encoches et accompagnent ainsi les produits sans les dégrader.In this way, during the retraction of the products during drying, the rollers rotate gradually in the notches and thus accompany the products without degrading them.
Un tel dispositif de séchage ménage toutefois peu d'espace entre les différents rouleaux supports. L'air peut alors difficilement circuler au niveau de la face inférieure des produits et le séchage n'est pas effectué de façon uniforme et efficace. Une hétérogénéité du séchage entraîne alors des dégradations des produits et des temps de séchage plus longs.Such a drying device, however, provides little space between the different support rollers. The air can then hardly circulate at the bottom face of the products and the drying is not performed uniformly and efficiently. Heterogeneity of drying then leads to product degradation and longer drying times.
L'invention vise à remédier à cet inconvénient en proposant un dispositif de séchage garantissant une bonne homogénéité et un temps réduit de séchage des produits, tout en évitant leur dégradation.The invention aims to overcome this disadvantage by providing a drying device ensuring good homogeneity and reduced drying time of the products, while avoiding their degradation.
Le document
La structure des encoches ne permet pas un pivotement des éléments supports dans les encoches, mais uniquement un déplacement selon l'axe longitudinal, de sorte que, soit le support se déplace en frottant dans l'encoche, soit le bord supérieur du support se déplace en frottant par rapport à la surface inférieure du produit. En particulier dans le cas où le jeu est très faible, il se peut donc que le bord supérieur de l'élément support frotte contre la paroi inférieure des produits, ce qui entraîne une dégradation de ceux-ci.The structure of the notches does not allow pivoting of the support elements in the notches, but only a displacement along the longitudinal axis, so that either the support moves by rubbing in the notch, or the upper edge of the support moves by rubbing with respect to the lower surface of the product. Especially in the case where the clearance is very low, it is therefore possible that the upper edge of the support element rubs against the bottom wall of the products, resulting in degradation thereof.
A cet effet, l'invention concerne un dispositif de séchage d'un produit en céramique, notamment en argile, comportant un premier et un second longerons comprenant chacun une pluralité d'encoches, et une pluralité d'éléments supports allongés présentant la forme d'une plaque disposée sensiblement, verticalement, chaque élément support présentant un bord supérieur sur lequel le produit à sécher est destiné à venir reposer, ainsi qu'une première et une seconde extrémités reposant dans des encoches, caractérisé en ce que chaque encoche est ménagée dans la face supérieure d'un longeron, le bord inférieur des extrémités des éléments supports repose sur le fond d'une encoche, et les extrémités des éléments supports et les encoches sont conçues pour permettre le pivotement des éléments supports dans les encoches.To this end, the invention relates to a device for drying a ceramic product, in particular clay, comprising a first and a second longitudinal members each comprising a plurality of notches, and a plurality of elongated support elements having the form of a plate disposed substantially vertically, each support member having an upper edge on which the product to be dried is intended to rest, and first and second ends resting in notches, characterized in that each notch is provided in the upper face of a spar, the lower edge of the ends of the support members rests on the bottom of a notch, and the ends of the support elements and the notches are designed to allow pivoting of the support elements in the notches.
La forme des plaques et leur orientation permettent de ménager un jour important entre les différents éléments supports, de sorte que le flux d'air atteignant la paroi inférieure des produits à sécher n'est pas entravé. Le séchage des produits est donc effectué de manière homogène et efficace.The shape of the plates and their orientation make it possible to arrange a significant day between the different support elements, so that the air flow reaching the bottom wall of the products to be dried is not hindered. The drying of the products is therefore performed in a homogeneous and efficient manner.
Le fait que les extrémités des éléments support reposent contre le fond des encoches permet de diminuer l'encombrement, en particulier la hauteur, du dispositif de séchage.The fact that the ends of the support elements rest against the bottom of the notches makes it possible to reduce the size, in particular the height, of the drying device.
En outre, le pivotement des supports garantit que le bord supérieur de ces derniers ne crée pas de contrainte sur la face inférieure des produits, la rétractation des produits étant complètement absorbée par le pivotement.In addition, the pivoting of the supports ensures that the upper edge of the latter does not create stress on the underside of the products, the retraction of the products being completely absorbed by the pivoting.
Selon une caractéristique de l'invention, les extrémités de chaque plaque sont formées par deux pattes disposées dans la partie supérieure de celle-ci, s'étendant vers l'extérieur et reposant sur le fond des encoches.According to a feature of the invention, the ends of each plate are formed by two tabs disposed in the upper part thereof, extending outwardly and resting on the bottom of the notches.
De cette manière, les éléments supports peuvent pivoter le long de l'arête de contact entre les pattes et le fond des encoches correspondantes.In this way, the support members can pivot along the contact edge between the tabs and the bottom of the corresponding notches.
Avantageusement, le bord supérieur des éléments supports présente une section arrondie ou en pointe.Advantageously, the upper edge of the support elements has a rounded or pointed section.
Selon une forme de réalisation de l'invention, chaque encoche présente une forme générale conique s'évasant vers l'extérieur.According to one embodiment of the invention, each notch has a generally conical shape flaring outwards.
Préférentiellement, chaque élément support est agencé de manière à ce que son centre de gravité soit disposé sous l'axe de pivotement formé par la ligne de contact entre les extrémités latérales et les encoches.Preferably, each support element is arranged so that its center of gravity is disposed under the pivot axis formed by the line of contact between the lateral ends and the notches.
De cette manière, lors du séchage, les éléments supports peuvent être amenés à pivoter afin de compenser le retrait dimensionnel des produits et sont ainsi décalés de leur position verticale d'équilibre. Après retrait des produits, le poids des éléments supports tend à rappeler ces derniers dans leur position verticale, de sorte qu'il n'est pas nécessaire de les replacer avant un autre cycle de séchage de produits.In this manner, during drying, the support members can be pivoted to compensate for the dimensional shrinkage of the products and are thus offset from their vertical equilibrium position. After removal of the products, the weight of the support elements tends to recall the latter in their vertical position, so that it is not necessary to replace them before another drying cycle of products.
Selon une caractéristique de l'invention, au moins une des encoches ou au moins l'un des éléments supports est équipé de moyens de limitation de la rotation ou d'immobilisation de l'élément support correspondant, par exemple une cale ou un coin.According to a characteristic of the invention, at least one of the notches or at least one of the support elements is equipped with means for limiting the rotation or immobilization of the corresponding support element, for example a shim or a wedge.
L'immobilisation d'au moins un élément support permet de maintenir le produit dans une position d'équilibre stable et d'éviter que les éléments supports basculent tous d'un même côté.The immobilization of at least one support element makes it possible to keep the product in a stable equilibrium position and to prevent the support elements from all tilting on the same side.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemple, une forme de réalisation de ce dispositif de séchage.

Un dipositif de séchage selon l'invention est illustré aux
Chaque longeron comporte une surface supérieure 3 dans laquelle sont ménagées des encoches 4 régulièrement espacées les unes des autres.Each spar comprises an
Chaque encoche présente une forme générale conique s'évasant vers le haut, les encoches du premier longeron étant ménagées en regard de celles du second longeron.Each notch has a generally conical shape flaring upwards, the notches of the first spar being arranged opposite those of the second spar.
Le dispositif de séchage comporte en outre une pluralité d'éléments supports 5 en forme de plaque.The drying device further comprises a plurality of plate-like support members.
Chaque élément support 5 présente, en vue de face et comme cela est illustré à la
Les éléments supports 5 sont montés dans les encoches 4, sensiblement perpendiculairement aux longerons 1, 2, de manière à ce que le bord inférieur 11 des pattes 9, 10 soit en contact contre le fond des encoches 4 correspondantes. Dans la forme de réalisation représentée aux figures, seule une partie des longerons 1, 2 est équipée des éléments supports 5 et, dans cette partie, seule une encoche 4 sur deux est équipée d'un élément support 5. L'espacement des éléments supports 5 est dépendant des dimensions des produits à sécher ainsi que des conditions de séchage. Il est donc possible de d'ajuster un tel écartement en fonction des besoins, celui-ci pouvant être n'importe quel multiple de la distance entre deux encoches 4.The support elements 5 are mounted in the notches 4, substantially perpendicular to the
Le bord supérieur 8 des éléments supports 5 et/ou le bord inférieur 11 des pattes 9, 10 présentent une section arrondie ou en forme de pointe.The
La partie médiane 6 s'étend vers le bas au-delà des pattes, le centre de gravité G de chaque élément support étant alors disposé sous le bord inférieur 11 des pattes 9, 10.The median portion 6 extends downwardly beyond the tabs, the center of gravity G of each support element being then disposed under the
Ainsi, lorsqu'aucun effort n'est exercé sur les éléments supports 5, ces derniers sont rappelés dans une position d'équilibre verticale.Thus, when no force is exerted on the support elements 5, the latter are recalled in a position of vertical equilibrium.
Afin de faire sécher des produits en argile 12, par exemple des briques, ces derniers sont posés sur les éléments supports 5 orientés verticalement. Cette position est représentée à la
L'un des éléments supports, plus particulièrement celui désigné par la référence 13, est immobilisé en position verticale, de manière à définir une position stable des produits 12 et éviter le basculement de tous les éléments supports 5 d'un même côté. L'immobilisation peut être réalisée par l'intermédiaire d'un coin ou d'un cavalier monté dans la ou les encoches correspondantes (non représenté).One of the support elements, more particularly that designated by the
Lors du séchage, le flux d'air chaud peut ainsi facilement traverser les espaces ménagés entre deux éléments supports 5 et atteindre la paroi inférieure des produits 12. La surface ne pouvant pas être atteinte par le flux d'air chaud est quasi nulle et correspond aux zones de contact entre le bord supérieur 8 effilé des éléments supports 5 et la paroi inférieure des produits 12.During drying, the flow of hot air can easily pass through the spaces formed between two support elements 5 and reach the bottom wall of the
Lors de cette opération de séchage, les produits 12 sont soumis à un retrait dimensionnel. Les éléments supports 5 accompagnent alors progressivement ce retrait en pivotant autour du bord inférieur 11 des pattes 9, 10.During this drying operation, the
Plus particulièrement, les éléments supports 5 disposés de l'un des côté de l'élément support immobilisé 13 pivotent dans le sens contraire de ceux situés du côté opposé, comme cela est illustré à la
Les formes arrondies ou en pointe du bord supérieur 8 et des bords inférieurs 11 des pattes 9, 10 facilitent le pivotement des éléments supports 5.The rounded or pointed shapes of the
Après séchage, les produits 12 sont retirés des éléments supports 5 et ceux-ci retrouvent leur position verticale d'équilibre.After drying, the
Le dispositif de séchage peut alors être réutilisé pour un nouveau cycle de séchage de produits.The drying device can then be reused for a new drying cycle of products.
On remarque ainsi que le dispositif présenté ci-dessus permet d'éviter une dégradation des produits lors du séchage, tout en garantissant une bonne homogénéité et un temps réduit de séchage des produits.It is thus noted that the device presented above makes it possible to avoid degradation of the products during drying, while ensuring good homogeneity and reduced drying time of the products.
Comme il va de soi l'invention ne se limite pas à la seule forme de réalisation de ce dispositif, décrite ci-dessus à titre d'exemple, mais elle embrasse au contraire toutes les variantes. C'est ainsi notamment que celui-ci pourrait comporter plus de deux longerons.It goes without saying that the invention is not limited to the sole embodiment of this device, described above as an example, but it embraces all variants. This is particularly that it could include more than two longitudinal members.
