Abstract

The fitter, designed to press refractory blocks (4) coated with mortar against the surface of an incineration heater screen made from flat sections (5) and tubes (8), consists of a lever (1) set perpendicular to the surface of the screen and a second lever (2) parallel to it. The two levers are connected by an angled strut (3), and the perpendicular is equipped with a device (9) to secure it to the heads of studs (6) welded to the flat sections between the tubes.

Description

La présente invention a pour objet un dispositif de pressage pour la pose sûre des pièces réfractaires des écrans de chaudières d'incinération. The present invention relates to a pressing device for the safe installation of refractory parts of the screens of incineration boilers.

La pose des pièces réfractaires des écrans de chaudières d'incinération, après le graissage de pâte à maçonner des pièces réfractaires, se fait en frappant lesdites pièces réfractaires de façon à les placer le mieux possible contre la chaudière d'incinération. Le problème avec ce type de pose manuelle, c'est que l'on risque d'endommager les pièces réfractaires et que la pose n'est pas toujours précise et propre. De plus, le poseur est obligé de maintenir les pièces réfractaires contre l'écran de manière à ce que la pâte à maçonner prenne, ce qui engendre une perte de temps, oblige l'utilisation d'une main d'oeuvre plus conséquente d'où une augmentation du coût du chantier. Enfin, cette pose n'est pas "confortable" pour le poseur car elle l'oblige à appuyer sur la pièce réfractaire sans réel point d'appui. The installation of the refractory pieces of the screens of incineration boilers, after the lubrication of masonry paste of the refractory pieces, is done by striking said refractory pieces so as to place them as best as possible against the incineration boiler. The problem with this type of manual installation is that there is a risk of damaging the refractory parts and that the installation is not always precise and clean. In addition, the installer is obliged to hold the refractory pieces against the screen so that the masonry paste sets, which generates a loss of time, obliges the use of a more substantial workforce of where an increase in the cost of the site. Finally, this pose is not "comfortable" for the installer because it forces him to press on the refractory piece without real point of support.

L'invention a pour but de remédier aux inconvénients des poses classiques des pièces réfractaires des écrans de chaudières d'incinération tels que présentés cidessus. The object of the invention is to remedy the drawbacks of conventional installations of refractory parts of the screens of incineration boilers as presented above.

Conformément à l'invention, ce résultat est obtenu avec un dispositif de pressage pour la pose sûre des pièces réfractaires des écrans de chaudières caractérisé en ce qu'il comporte essentiellement un levier perpendiculaire au plan des faces de l'incinérateur qui est en équerre à un levier parallèle au plan des faces de l'incinérateur. According to the invention, this result is obtained with a pressing device for the safe installation of refractory pieces of boiler screens, characterized in that it essentially comprises a lever perpendicular to the plane of the faces of the incinerator which is at right angles to a lever parallel to the plane of the faces of the incinerator.

On comprendra mieux l'invention à l'aide de la description faite ci-après d'un mode préférentiel de mise en oeuvre, donné à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels
- la figure I est une vue du dessus du levier de pressage lors de la pose d'une pièce réfractaire d'écrans de chaudières d'incinération,
- la figure 2 est une vue de face du levier de pressage lors de la pose d'une pièce réfractaire d'écrans de chaudières d'incinération. The invention will be better understood with the aid of the description given below of a preferred embodiment, given by way of nonlimiting example, with reference to the appended drawings in which
FIG. I is a top view of the pressing lever during the fitting of a refractory part of screens of incineration boilers,
- Figure 2 is a front view of the pressing lever during the installation of a refractory part of screens of incineration boilers.

- les figures 3a et 3b sont des vues en perspective illustrant la façon dont se fait la liaison entre un élément d'arrimage et des têtons soudés sur les plats entre les tubes de l'incinérateur. - Figures 3a and 3b are perspective views illustrating the way in which the connection is made between a lashing element and pins welded to the plates between the tubes of the incinerator.

Le dispositif de pressage pour la pose sûre des pièces réfractaires se compose essentiellement en un levier perpendiculaire (1) au plan des faces de l'incinérateur (3) où sont posées les pièces réfractaires (4) qui est en équerre avec un levier parallèle (2) au plan des faces de l'incinérateur. Une pièce (3) lie le levier parallèle (2) et le levier perpendiculaire (1) de façon à former une potence. The pressing device for the safe installation of refractory pieces essentially consists of a lever perpendicular (1) to the plane of the faces of the incinerator (3) where the refractory pieces (4) are placed, which is square with a parallel lever ( 2) on the plane of the faces of the incinerator. A piece (3) links the parallel lever (2) and the perpendicular lever (1) so as to form a bracket.

Le dispositif de pressage comprend également un élément d'arrimage (9) dans le prolongement de l'axe du levier perpendiculaire (1) qui se fixe solidement aux tétons (6) soudés sur les plats entre les tubes (8) de l'incinérateur (5) tel que représenté sur les figures 3a et 3b. Cet arrimage constitue un point d'appui pour notre dispositif de pressage. The pressing device also comprises a lashing element (9) in the extension of the axis of the perpendicular lever (1) which is firmly fixed to the pins (6) welded on the plates between the tubes (8) of the incinerator. (5) as shown in Figures 3a and 3b. This stowage constitutes a fulcrum for our pressing device.

Dans l'exemple présent, on cale une pièce de bois entre le levier parallèle (2) et la pièce réfractaire (4) préalablement graissée de pâte à maçonner posée contre 'incinérateur.  In the present example, a piece of wood is wedged between the parallel lever (2) and the refractory piece (4) previously greased with masonry paste placed against the incinerator.

Lorsque l'on exerce une force F (figure 1) sur le levier (1), on crée une pression P sur la pièce réfractaire qui est ainsi plaquée contre l'incinérateur. When a force F (FIG. 1) is exerted on the lever (1), pressure P is created on the refractory piece which is thus pressed against the incinerator.

La présente invention permet une pose sûre et rapide. La pièce réfractaire à poser n'est plus frappée. La pression créée au niveau de la pièce réfractaire à poser est uniforme sur l'ensemble de ladite pièce. Ainsi la pâte à maçonner est parfaitement répartie entre les pièces et les tubes d'écran de I 'incinérateur et le risque de vide entre les pièces et les tubes d'écran est éliminé. On récupère facilement l'excédent de pâte à maçonner d'où un travail de pose plus propre. The present invention allows safe and rapid installation. The refractory piece to be laid is no longer struck. The pressure created at the level of the refractory part to be laid is uniform over the whole of said part. Thus the masonry paste is perfectly distributed between the parts and the screen tubes of the incinerator and the risk of vacuum between the parts and the screen tubes is eliminated. We easily recover the excess masonry paste where a cleaner installation work.

Les pièces réfractaires déjà posées maintenues par le dispositif de pressage ne se décollent plus de l'incinérateur (5) car la pâte a le temps de sécher puisqu'on laisse le dispositif en place jusqu'à ce que la pâte à maçonner ait prise.  The refractory parts already placed maintained by the pressing device no longer detach from the incinerator (5) because the dough has time to dry since the device is left in place until the masonry dough has set.
