Description

La présente invention porte sur un plaque support de brûleur pour chaudières en fonte.The present invention relates to a burner support plate for cast iron boilers.

Les dites plaques support de brûleur peuvent être fixes ou mobiles autour d'un axe de rotation vertical, elles constituent alors une porte d'accès au foyer.Said burner support plates can be fixed or mobile around a vertical axis of rotation, they then constitute an access door to the hearth.

Actuellement les portes en fonte utilisées sur les plaques support de brûleur pour chaudières, sont pourvues de gonds venus de fonderie, mais percés par usinage pour créer les logements de l'axe de rotation. Ce procédé nécessite le transport de la pièce de la fonderie à l'atelier d'usinage et son coût est élevé.Currently the cast iron doors used on the burner support plates for boilers are provided with hinges from the foundry, but drilled by machining to create the housings of the axis of rotation. This process requires transportation of the part from the foundry to the machine shop and its cost is high.

Le problème est identique pour les charnières en fonte devant coopérer avec les gonds ci-dessus. De plus, la solution actuelle nécessite l'utilisa­tion d'un axe dont la tête est forgée pour maintenir l'axe en place.The problem is the same for cast iron hinges that have to cooperate with the above hinges. In addition, the current solution requires the use of an axis whose head is forged to hold the axis in place.

L'isolation d'une plaque support de brûleur se fait actuellement avec un produit réfractaire moulé ou fibreux fixé sur la plaque support de brûleur par des boulons ou des vis.The insulation of a burner support plate is currently done with a molded or fibrous refractory product fixed on the burner support plate by bolts or screws.

Dans le cas de la fixation par boulons, les dits boulons traversent l'isolante, provoquant des ponts thermiques.In the case of fixing by bolts, the said bolts pass through the insulation, causing thermal bridges.

Dans le cas de la fixation par vis, il faut prévoir des inserts dans l'isolant.In the case of screw fixing, inserts must be provided in the insulation.

Les deux solutions sont chères.Both solutions are expensive.

En ce qui concerne le montage du brûleur sur la plaque support de brûleur, la technique actuelle consiste à utiliser une pièce en aluminium qui se boulonne sur le support de brûleur.Regarding the mounting of the burner on the burner support plate, the current technique consists in using an aluminum piece which is bolted to the burner support.

Cette pièce supplémentaire augmente également le coût de la chaudière.This additional part also increases the cost of the boiler.

Le but de la présente invention est de diminuer le prix de revient de la plaque support de brûleur, en supprimant les usinages, les boulons, les vis, en facilitant le montage, tout en conservant les qualités du produit.The object of the present invention is to reduce the cost price of the burner support plate, by eliminating the machining, the bolts, the screws, by facilitating assembly, while retaining the qualities of the product.

Ce but est atteint grâce à une plaque support de brûleur pour chaudière en fonte, caractérisée en ce qu'elle comporte au moins un élément venu de fonderie du type (cavité, gond, demi bride) apte à recevoir un élément complémentaire sans nécessiter d'usinage.This object is achieved by means of a burner support plate for a cast iron boiler, characterized in that it comprises at least one element from the foundry of the type (cavity, hinge, half flange) capable of receiving an additional element without requiring machining.

La plaque support de brûleur, objet de l'invention, pallie tous les inconvénients de l'art antérieur.The burner support plate, object of the invention, overcomes all the drawbacks of the prior art.

Selon un premier mode de réalisation non limitatif, la plaque support de brûleur est mobile en rotation et constitue la porte d'accès au foyer de la chaudière, la dite porte pouvant s'ouvrir à droite ou à gauche.According to a first non-limiting embodiment, the burner support plate is movable in rotation and constitutes the access door to the boiler hearth, said door being able to open to the right or to the left.

Ce premier mode de réalisation correspond aux figures 1 à 5 et à la figure 8.This first embodiment corresponds to FIGS. 1 to 5 and to FIG. 8.

Ces figures montrent une plaque (1) venue de fonderie comportant des gonds (2), une demi-bride (3), des butées (5), une cavité (6) munie d'une pluralité de picots (7), tous ces éléments venus également de fonderie.These figures show a plate (1) from the foundry comprising hinges (2), a half-flange (3), stops (5), a cavity (6) provided with a plurality of pins (7), all of these elements also from foundry.

Les gonds (2) sont adaptés pour coopérer avec une pièce complémentaire, la charnière (8) montrée en détail aux figures 4 et 5.The hinges (2) are adapted to cooperate with an additional part, the hinge (8) shown in detail in FIGS. 4 and 5.

La figure 10 montre à plus grande échelle un gond (2), les sections suivant les plans EE, FF, GG des figures 10a, 10b, 10c montrent le détail du gond (2) conforme au mode de réalisation préféré non limitatif de l'invention.FIG. 10 shows on a larger scale a hinge (2), the sections along the planes EE, FF, GG of FIGS. 10a, 10b, 10c show the detail of the hinge (2) in accordance with the preferred nonlimiting embodiment of the invention.

Deux demi-brides (2a) et (2b) venues de fonderie avec la plaque (1) ont pour fonction de maintenir l'axe de rotation non représenté.Two half-flanges (2a) and (2b) from the foundry with the plate (1) have the function of maintaining the axis of rotation not shown.

La charnière (8) comporte en son centre un trou (9) pour la fixation de la dite charnière (8) sur un élément de façade de la chaudière comme cela est schématisé en figure 9, à titre d'exemple non limitatif.The hinge (8) has in its center a hole (9) for fixing the said hinge (8) on a front element of the boiler as is shown diagrammatically in FIG. 9, by way of nonlimiting example.

Lors du montage, un axe ou simple tige d'acier, non représenté, est mis en place par le haut, traverse de façon connue en soi les gonds (2) et charnière (8) et vient buter sur la butée (5) venue de fonderie (voir fig.11).During assembly, a pin or simple steel rod, not shown, is put in place from above, crosses in a manner known per se the hinges (2) and hinge (8) and abuts on the stop (5) coming foundry (see fig. 11).

Le dit axe de rotation est mis en place soit à droite, soit à gauche de la porte selon le sens d'ouverture choisi.Said axis of rotation is set up either to the right or to the left of the door depending on the direction of opening chosen.

Bien entendu on ne sortirait pas du cadre de l'invention en fabriquant une plaque (1) comportant uniquement deux gonds (2) d'un seul côté de la plaque support de foyer.Of course, it would not go beyond the scope of the invention to manufacture a plate (1) comprising only two hinges (2) on one side of the hearth support plate.

Sur le présent mode de réalisation, les usinages sont supprimés, ainsi que l'axe spécial à tête forgée utilisé auparavent.In the present embodiment, the machining operations are eliminated, as well as the special axis with forged head used previously.

D'autre part la fixation de la charnière est simple, elle est fixée par un boulon positionné sur une nervure (fig.9) ou une oreille, ou un loge­ment, prévus sur l'élément de façade de la chaudière, et venus également de fonderie.On the other hand, the fixing of the hinge is simple, it is fixed by a bolt positioned on a rib (fig. 9) or a lug, or a housing, provided on the front element of the boiler, and also from foundry.

La plaque (1) qui vient d'être décrit et qui constitue une porte d'accès au foyer de la chaudière, a également pour fonction de porter le brûleur non représenté.The plate (1) which has just been described and which constitutes an access door to the boiler hearth, also has the function of carrying the burner, not shown.

Dans ce but, une demi-bride (3) est prévue au centre de la plaque (1). Cette demi-bride présente la forme et la dimension du modèle de fût du brûleur choisi.For this purpose, a half-flange (3) is provided in the center of the plate (1). This half flange presents the shape and size of the barrel model of the selected burner.

Lors du montage, le fût du dit brûleur est positionné dans la demi-­bide (3) où il repose par gravité.During assembly, the barrel of said burner is positioned in the half-flange (3) where it rests by gravity.

Une autre demi-bride (4), par exemple celle de la figure 8, est positionnée au dessus du fût du brûleur et en regard de la demi-bride (3). Les deux demi-brides (3) et (4) sont deux pièces complémentaires.Another half-flange (4), for example that of FIG. 8, is positioned above the burner barrel and opposite the half-flange (3). The two half-flanges (3) and (4) are two complementary parts.

Des moyens de fixation, par exemple des trous ou lumières (10) (11) venus de fonderie, sont prévus dans des oreilles ou prolongements des deux demi-brides (3) (4). Le serrage peut être effectué par des boulons non repré­sentés. On peut prévoir d'autres moyens de fixation ou de serrage sans sortir du cadre de l'invention.Fixing means, for example holes or lights (10) (11) from the foundry, are provided in ears or extensions of the two half-flanges (3) (4). Tightening can be carried out by bolts not shown. Other fixing or tightening means can be provided without departing from the scope of the invention.

La plaque (1) support de brûleur comporte en outre une cavité (6) pour la mise en place d'une isolation.The burner support plate (1) further includes a cavity (6) for installing insulation.

La dite cavité (6) est plus particulièrement visible sur les figures 2, 3. On prévoit dans cette cavité (6) une pluralité de picots (7), par exemple quatre.Said cavity (6) is more particularly visible in Figures 2, 3. There is provided in this cavity (6) a plurality of pins (7), for example four.

La forme et les dimensions de la cavité (6), et des picots (7) représentés ne sont pas limitatifs, d'autres variantes de réalisation peuvent être imaginées.The shape and dimensions of the cavity (6), and the pins (7) shown are not limiting, other alternative embodiments can be imagined.

Par exemple, les croquis 8 et 9 montrent une de ces variantes, où, par souci de clarté, la demi-bride support de brûleur ne figure pas.For example, sketches 8 and 9 show one of these variants, where, for the sake of clarity, the burner support half-flange does not appear.

Sur la figure 7, un bloc d'isolation (12) est mis en place dans la cavité, le dit bloc d'isolation (12) présente une forme complémentaire de celle de la cavité, il comporte un trou pour le passage du fût du brûleur, et les picots (7) se mettent en place dans des trous venus de moulage ou de perçage dans l'isolation. Dans toutes les variantes, on peut prévoir de com­pléter la fixation de l'isolation par une colle ou un mastic introduit dans les trous de l'isolant au moment du montage.In FIG. 7, an insulation block (12) is placed in the cavity, the said insulation block (12) has a shape complementary to that of the cavity, it has a hole for the passage of the barrel of the burner, and the pins (7) are placed in holes from molding or drilling in the insulation. In all variants, provision may be made to complete the fixing of the insulation with an adhesive or a putty introduced into the insulation holes at the time of assembly.

Les moyens de fixation de l'isolation qui viennent d'être décrits permettent de supprimer les boulons, les vis, les ponts thermiques, de réduire le nombre de pièces et la durée du montage, donc de diminuer le coût de la chaudière. Ce mode de fixation de l'isolation peut être utilisé aussi bien sur une plaque support de brûleur mobile autour d'un axe de rotation ( figures 1 à 5) que sur une plaque foyère destinée à être fixée sur la chaudière (figures 6 et 7).The means of fixing the insulation which have just been described make it possible to remove the bolts, the screws, the thermal bridges, to reduce the number of parts and the duration of the assembly, therefore to reduce the cost of the boiler. This method of fixing the insulation can be used both on a burner support plate movable around an axis of rotation (Figures 1 to 5) as on a stove plate intended to be fixed on the boiler (Figures 6 and 7 ).

Dans toute la description et dans les revendications on comprendra que l'expression "venu (s) de fonderie" signifie "venu (s) de fonderie avec la plaque (1).Throughout the description and in the claims, it will be understood that the expression "foundry member (s)" means "foundry member (s) with the plate (1).
