Description

La présente invention concerne un procédé de préparation d'un mélange composé de fibres minérales et de liants hydrauliques et organiques en particules ou liquides.The present invention relates to a process for preparing a mixture composed of mineral fibers and hydraulic and organic binders in particles or liquids.

De tels mélanges composés en général de laine de laitier ou de laine de roche volcanique, de ciment et de silicate en particules et d'huile sont en général destinés à être appliqués, après addition d'eau, par projection sur une surface pour réaliser un revêtement présentant des propriétés d'isolation, thermique et acoustique et de coupe-feu.Such mixtures generally composed of slag wool or volcanic rock wool, cement and silicate particles and oil are generally intended to be applied, after addition of water, by spraying onto a surface to achieve a coating with insulation, thermal and acoustic properties and fire resistance.

Actuellement, pour la préparation d'un tel mélange, on introduit dans un tambour une quantité déterminée de fibres minérales, une quantité déterminée de ciment, une quantité déterminée de silicate et une quantité déterminée d'huile. On fait tourner ce tambour pendant un temps déterminé nécessaire à l'obtention du mélange souhaité et on évacue le mélange obtenu. Pour obtenir une autre quantité de mélange, on répète ces opérations. Il s'ensuit que ce procédé, du type répétitif ou séquentiel, ne permet pas d'obtenir des débits importants de telle sorte que les coûts de préparation de ce mélange sont relativement élévés.Currently, for the preparation of such a mixture, a determined quantity of mineral fibers, a determined quantity of cement, a determined quantity of silicate and a determined quantity of oil are introduced into a drum. This drum is rotated for a determined time necessary to obtain the desired mixture and the mixture obtained is discharged. To obtain another quantity of mixture, these operations are repeated. It follows that this process, of the repetitive or sequential type, does not make it possible to obtain significant flow rates so that the costs of preparation of this mixture are relatively high.

La présente invention vise à remédier aux inconvénients de l'etat de la technique et propose tout d'abord un procédé de prépa- ratior d'un mélange composé de fibres minérales et de liants hydrauliques et inorganiques en particules ou liquides consistant à défibrer en coitinu une balle de fibres, à transporter en continu les fibres jusque l'entrée d'un transporteur-mélangeur à vis, à additionner en continu, pendant leur cheminement, les liants aux fibres et à évacuer à la sortie du transporteur-mélangeur à vis le mélange obtenu.The present invention aims to remedy the drawbacks of the state of the art and firstly proposes a process for the preparation of a mixture composed of mineral fibers and hydraulic and inorganic binders in particles or liquids consisting of defibrating in coitinu a bale of fibers, to continuously transport the fibers to the inlet of a screw conveyor-mixer, to continuously add, during their journey, the binders to the fibers and to evacuate at the outlet of the screw conveyor-mixer mixture obtained.

Le procédé selon la présente invention consiste également a incorporer aux fibres, lors de leur cheminement, par exemple du ciment et du silicate.The method according to the present invention also consists in incorporating into the fibers, as they travel, for example cement and silicate.

Le procédé selon la présente invention consiste en outre à encorporer aux fibres, lors de leur cheminement dans le transporteur mélangeur à vis, par exemple de l'huile.The method according to the present invention also consists in incorporating into the fibers, during their passage in the screw mixer conveyor, for example oil.

La présente invention se rapporte également à un disposi if pour la préparation d'un mélange composé de fibres minérales et de iants hydrauliques et inorganiques en particules ou liquides. pour 1a mise en oeuvre du procédé ci-dessus. Ce dispositif comprend des moyens de support d'au moins une balle de fibres, des moyens pour défibrer en continu cette balle, des moyens pour transporter en continu les fibres jusqu'à l'entrée d'un transporteur-mélangeur à vis, des moyens pour en continu additionner aux fibres, lors de leur cheminement, les liants et des moyens pour évacuer le mélange obtenu, à la sortie du transporteur-mélangeur à vis.The present invention also relates to a device for the preparation of a mixture composed of mineral fibers and hydraulic and inorganic iants in particles or liquids. for the implementation of the above process. This device comprises means for supporting at least one bale of fibers, means for continuously defibrating this bale, means for continuously transporting the fibers up to the entrance of a screw conveyor-mixer, means to continuously add to the fibers, during their passage, the binders and means for evacuating the mixture obtained, at the outlet of the screw conveyor-mixer.

Selon la présente invention, lesdits moyens de support de la balle de fibres sont de préférence formés par un transporteur à bande, les moyens pour défibrer cette balle étant formés par au moins un rouleau à dents vers lequel ledit transporteur à bande déplace la balle de fibres.According to the present invention, said means for supporting the bale of fibers are preferably formed by a conveyor belt, the means for defibrating this bale being formed by at least one tooth roller towards which said conveyor belt moves the bale of fibers .

Selon la présente invention, lesdits moyens pour transporter lesdites fibres jusqu'à l'entrée du transporteur-mélangeur à vis comprennent de préférence au moins un transporteur à bande.According to the present invention, said means for transporting said fibers to the inlet of the screw conveyor-mixer preferably comprises at least one belt conveyor.

Selon la présente invention, lesdits moyens pour additionner les liants en particules comprennent de préférence un réservoir pour le liant et un transporteur a vis pour amener et déverser en continu ce liant sur le chemin des fibres.According to the present invention, said means for adding the particle binders preferably comprises a reservoir for the binder and a screw conveyor for continuously bringing and discharging this binder on the path of the fibers.

Selon la présente invention, une série de gicleurs permettant de pulvériser de l'huile sur les fibres dans le transporteur-mélangeur à vis peut être prévue.According to the present invention, a series of nozzles making it possible to spray oil on the fibers in the screw-mixing conveyor can be provided.

La présente invention sera mieux comprise à l'étude d'un dispositif pour la préparation d'un mélange composé de fibres minérales, de ciment et de silicate en particules et d'huile, décrit à titre d'exemple non limitatif et illustré par le dessin sur lequel :

  • - la figure 1 représente une vue en élévation de la chaîne de préparation ;
  • - la figure 2 représente une vue transversale en élévation du dispositif représenté sur la figure 1 ;
  • et la figure 3 représente une coupe selon III-III du dispositif représenté sur la figure 1.
The present invention will be better understood from the study of a device for the preparation of a mixture composed of mineral fibers, of cement and of silicate in particles and of oil, described by way of nonlimiting example and illustrated by drawing on which:
  • - Figure 1 shows an elevational view of the preparation line;
  • - Figure 2 shows a transverse elevational view of the device shown in Figure 1;
  • and FIG. 3 represents a section on III-III of the device shown in FIG. 1.

Le dispositif représenté sur les figures et repéré; d'une manière générale par la référence 1 comprend un transporteur horizontal à bande. 2 sur lequel on dispose une balle 3 de fibres minérales telles que de la laine de laitier ou de la laine de roche volcanique ainsi que deux rouleaux horizontaux 4 et 5 placés l'un au dessus de l'autre. Les rouleaux 4 et 5 sont munis à leur périphérie 6e dents qui permettent de défibrer régulièrement et en continu la balle 3 lorsque cette dernière est déplacée par le transporteur horizontal 5 dans leur direction.The device shown in the figures and identified; generally by the reference 1 comprises a horizontal conveyor belt. 2 on which there is a ball 3 of mineral fibers such as slag wool or volcanic rock wool and two horizontal rollers 4 and 5 placed one above the other. Rollers 4 and 5 are provided at their periphery 6th teeth which allow the ball 3 to be defibrated regularly and continuously when the latter is moved by the horizontal conveyor 5 in their direction.

A l'extrémité du transporteur horizontal 2, les fibres provenant en continu de la balle 3 sont déversées sur un transporteur à bande 6 qui amène en continu les fibres sur la partie inférieure d'un transporteur à bande incliné 7.At the end of the horizontal conveyor 2, the fibers coming continuously from the bale 3 are discharged onto a belt conveyor 6 which continuously feeds the fibers onto the lower part of an inclined belt conveyor 7.

En se reportant à la figure 2, on voit que de chaque côté du transporteur à bande 7 sont prévus d'une part un réservoir de ciment en particules 8 et un réservoir de silicate en particules 9 qui sont munis à leur base de vis 10 et 11 de transport et de dosage dont les conduits de sortie 12 et 13 débouchent au-dessus du transporteur à bande 7 de manière à y déverser une quantité dosée de ciment et de silicate.Referring to FIG. 2, it can be seen that on each side of the belt conveyor 7 are provided on the one hand a tank of particulate cement 8 and a tank of particulate silicate 9 which are provided at their base with screws 10 and 11 for transport and metering, the outlet conduits 12 and 13 of which open above the conveyor belt 7 so as to pour a metered quantity of cement and silicate there.

Comme on peut le voir sur la figure 1, le transporteur à bande 7 déverse, en continu, les fibres, le ciment et le silicate qui lui ont été ajoutés dans une trémie 14 d'entrée d'un transporteur-mélangeur à vis 15 disposée horizontalement.As can be seen in FIG. 1, the belt conveyor 7 continuously pours the fibers, the cement and the silicate which have been added to it into an inlet hopper 14 of a screw mixer-mixer 15 arranged horizontally.

Comme on peut le voir sur la figure 3, le transporteur-mélangeur à vis 15 comprend deux vis 16 et 17 parallèles. Dans l'espace supérieur du transporteur-mélangeur à vis 15 s'étend longitudinalement un conduit 18 muni d'une série de gicleurs 19 orientés en direction de l'espace situé entre les vis 16 et 17. Ce conduit 18 est destiné à la pulvérisation d'huile provenant d'un réservoir 20, grâce à une pompe 21.As can be seen in Figure 3, the screw conveyor-mixer 15 comprises two parallel screws 16 and 17. In the upper space of the screw conveyor-mixer 15 extends longitudinally a conduit 18 provided with a series of nozzles 19 oriented in the direction of the space between the screws 16 and 17. This conduit 18 is intended for spraying oil from a reservoir 20, by a pump 21.

Dans le transporteur-mélangeur a vis 15, au cours de leur cheminement, les fibres minérales, le ciment et le silicate et l'huile se trouvent mélangés.In the screw conveyor-mixer 15, in the course of their journey, the mineral fibers, the cement and the silicate and the oil are mixed.

A son extrémité opposée à la trémie 14, le transporteur-mélangeur à vis 15 présente deux conduits 22 et 23 orientés vers le bas, ces conduits 22 et 23 permettant de déverser le mélange obtenu par exemple dans des sacs. Sur ces conduits 22 et 23 peuvent en outre être prévus des moyens d'aspiration des poussières, ces, moyens n'ayant pas été représentés.At its end opposite to the hopper 14, the screw conveyor-mixer 15 has two conduits 22 and 23 oriented downwards, these conduits 22 and 23 making it possible to pour the mixture obtained for example into bags. On these conduits 22 and 23 can also be provided dust suction means, these means have not been shown.

On voit sur la figure 2 qu'il a également été prévu un réservoir 24 de grande dimension pour le ciment, une vis élévatrice 25 permettant d'amener en continu le ciment depuis la base du réservoir 24 jusqu'au réservoir de ciment 8.It can be seen in FIG. 2 that a large tank 24 for cement has also been provided, an elevating screw 25 allowing the cement to be brought continuously from the base of the tank 24 to the cement tank 8.

Le dispositif 1 représenté.sur les figures et décrit ci-dessus permet d'obtenir ou de préparer en continu le mélange souhaité. En effet, en ajustant la vitesse de déplacement du transporteur 2 et la vitesse de rotation des rouleaux défibreurs 4 et 5, en ajustant la vitesse de rotation des vis de transport et de dosage 10 et 11, on amène à l'extrémité de l'entrée 14 du transporteur-mélangeur à vis 15, par l'intermédiaire des transporteurs à bande 6 et 7, la quantité de fibres souhaitée, 1a quantité de ciment souhaitée et la quantité de silicate souhaitée. Par un réglage de la pompe 21, on pulvérise, par l'intermédiaire des gicleurs 19, la quantité d'huile souhaitée. Il est bien entendu que la longueur du transporteur-mélangeur à vis 15 est adaptée pour obtenir à ses sorties 22 et 23 un mélange sensiblement homogène, les quantités mentionnées ci-dessus tenant compte de la longueur du transporteur-mélangeur à vis 15.The device 1 shown in the figures and described above makes it possible to continuously obtain or prepare the desired mixture. Indeed, by adjusting the speed of movement of the conveyor 2 and the speed of rotation of the defibrating rollers 4 and 5, by adjusting the speed of rotation of the transport and metering screws 10 and 11, it brings to the end of the input 14 of the screw mixer-conveyor 15, via the belt conveyors 6 and 7, the quantity of fibers desired, the quantity of cement desired and the quantity of silicate desired. By adjusting the pump 21, the desired quantity of oil is sprayed, via the nozzles 19. It is understood that the length of the screw conveyor-mixer 15 is adapted to obtain at its outputs 22 and 23 a substantially homogeneous mixture, the quantities mentioned above taking account of the length of the screw conveyor-mixer 15.

En se reportant aux figures 1 et 2, on voit que les différents éléments constituant le dispositif 1 sont portés par des poteaux et que le transporteur à bande- 7 est sur une grande partie de sa longueur entouré par un carénage 26. Bien entendu, la partie infé- riéure du transporteur à bande- 7, le transporteur à bandes 6 et l'ensemble formé par le transporteur à bande 2 et les rouleaux défibreurs 4 et 5 pourrait également être entouré par un carénage.Referring to FIGS. 1 and 2, it can be seen that the various elements constituting the device 1 are carried by posts and that the belt conveyor 7 is over a large part of its length surrounded by a fairing 26. Of course, the lower part of the conveyor belt 7, the conveyor belt 6 and the assembly formed by the conveyor belt 2 and the defibrating rollers 4 and 5 could also be surrounded by a fairing.

La présente invention ne se limite pas à l'exemple ci-dessus décrit. Bien des variantes de réalisation sont possibles sans sortir du cadre défini par les revendications annexées.The present invention is not limited to the example described above. Many alternative embodiments are possible without departing from the scope defined by the appended claims.
