Description

La présente invention concerne un transporteur de matières chaudes pour le transport et le refroidissement de matières en morceaux et en vrac à une température relativement élevée,le transporteur comportant une bande s-ans fin résistant à la chaleur,qui est guidée sur un tambour d'entrainement et sur un tambour de tension,ainsi que des lames métalliques placées étroitement les unes à côté des autres perpendiculairement à la direction de transport,une cavité ou une nappe d'isolation étant placée entre les lames et la bande transporteuse. The present invention relates to a hot material conveyor for transporting and cooling pieces and loose materials to a relatively high temperature, the conveyor comprising a thin heat-resistant strip which is guided on a drum. drive and on a tension drum, as well as metal blades placed closely next to each other perpendicular to the direction of transport, a cavity or an insulation sheet being placed between the blades and the conveyor belt.

Un transporteur de matières chaudes de ce genre est connu d'après le brevet autrichien n0228.125,suivant lequel il est prévu comme isolation thermique,entre autres, une structure à grille comportant une masse boueuse artificielle à effet d'aspiration,la protection de la bande transporteuse étant assurée par la matière chaude d'une part grâce à l'évaporation de l'humidité aspirée par la masse boueuse et d'autre part par l'action d'isolation de la couche déposée sur la bande transporteuse. A conveyor of hot materials of this kind is known from Austrian patent n0228.125, according to which it is provided as thermal insulation, inter alia, a grid structure comprising an artificial muddy mass with suction effect, the protection of the conveyor belt being provided by the hot material on the one hand thanks to the evaporation of the moisture sucked in by the muddy mass and on the other hand by the action of insulating the layer deposited on the conveyor belt.

L'invention a pour objet d'améliorer l'isolation thermique des lames d'une bande transporteuse de matières chaudes comportant des lames métalliques et utilisable avec une matière à température extrêmement élevée,comme du laitier de haut fourneau ou du clinker. The object of the invention is to improve the thermal insulation of the blades of a conveyor belt for hot materials comprising metal blades and usable with a material at an extremely high temperature, such as blast furnace slag or clinker.

Ce problème est résolu selon l'invention en ce que les lames,agencées avec une structure du type sandwich, comportent une plaque extérieure et une plaque intérieure entre lesquelles est disposée une couche thermiquement isolante, en ce que la plaque extérieure et la plaque intérieure sont reliées rigidement avec la couche d'isolation thermique à l'aide d'éléments extérieurs de fixation et en ce que pratiquement seulement les plaques intérieures placées en arrière des couches d'isolation thermique comportent des liaisons avec la bande transporteuse. This problem is solved according to the invention in that the blades, arranged with a sandwich type structure, comprise an outer plate and an inner plate between which is disposed a thermally insulating layer, in that the outer plate and the inner plate are rigidly connected with the thermal insulation layer by means of external fastening elements and in that practically only the internal plates placed behind the thermal insulation layers have connections with the conveyor belt.

I1 s'est avéré avantageux que la couche isolante soit agencée sous la forme d'une partie thermiquement isolante et libre qui limite considérablement la propagation de la chaleur de la plaque extérieure vers la plaque intérieure et qu'il soit prévu sur les éléments extérieurs de fixation des anneaux ou des manchons d'espacement les entourant et constitués d'un matériau thermiquement isolant. It has been found advantageous for the insulating layer to be arranged in the form of a thermally insulating and free part which considerably limits the propagation of heat from the external plate to the internal plate and to be provided on the external elements of fixing rings or spacers surrounding them and made of a thermally insulating material.

Dans une variante avantageuse de l'invention,il est prévu que,pour assurer une isolation complémentaire de la bande transporteuse ou des lames,les liaisons entre les plaques intérieures et la bande soient agencées sous la forme d'éléments intérieurs de fixation. In an advantageous variant of the invention, it is provided that, to ensure additional insulation of the conveyor belt or of the blades, the connections between the interior plates and the belt are arranged in the form of interior fixing elements.

Enfin,conformément à un autre mode avantageux de réalisation de l'invention,pour éviter un contact direct des éléments de fixation avec la bande ou avec les lames,il est prévu des deux côtés,dans la zone supérieure et dans la zone inférieure,des disques de guidage ayant avantageusement une section droite en forme de L,constitués d'une matière thermiquement isolante et servant à recevoir les éléments intérieurs de fixation. Finally, in accordance with another advantageous embodiment of the invention, to avoid direct contact of the fastening elements with the strip or with the blades, there are provided on both sides, in the upper zone and in the lower zone, Guide discs advantageously having an L-shaped cross section, made of a thermally insulating material and serving to receive the interior fixing elements.

D'autres avantages et caractéristiques de l'invention seront mis en évidence dans la suite de la descoription, donnée à titre d'exemple non limitatif,en référence aux dessins annexés dans lesquels:
Fig.l est une vue d'ensemble,et en coupe partielle, du transporteur conforme à l'invention;
Fig.2 est une coupe faite suivant la ligne a-a de la figure 1,
Fig.3 est une vue d'ensemble d'une variante de l'invention et
Fig.4 est une coupe faite suivant la ligne b-b de la figure 3.Other advantages and characteristics of the invention will be highlighted in the following description, given by way of nonlimiting example, with reference to the appended drawings in which:
Fig.l is an overall view, and in partial section, of the conveyor according to the invention;
Fig. 2 is a section taken along the line aa in FIG. 1,
Fig.3 is an overview of a variant of the invention and
Fig.4 is a section taken along line bb in Figure 3.

Le transporteur de matières chaudes comporte une bande sans fin l,formée d'un matériau réfractaire et qui est guidée sur un tambour d'entrainement et un tambour de tension, ainsi que des lames 2 placées étroitement les unes à côté des autres et orientées perpendiculairement à la direction de transport. The conveyor of hot materials comprises an endless belt l, formed of a refractory material and which is guided on a drive drum and a tension drum, as well as blades 2 placed closely next to each other and oriented perpendicularly to the direction of transport.

Les lames 2 ont une structure en sandwich et elles comportent des plaques extérieures spéciales 3 ainsi que des plaques intérieures 4 entre lesquelles sont placées des couches d'isolation thermique 5,les plaques extérieures 3 et les plaques intérieures 4 étant reliées rigidement avec les couches d'isolation thermique 5 à l'aide d'éléments extérieurs de fixation 6,qui sont agencés sous la forme d'éléments séparables,tels que des vis. Pour éviter dans une large mesure la transmission de chaleur entre les plaques extérieures 3 des lames 2 et la bande transporteuse l,les plaques intérieures 4,placées en arrière des couches d'isolation thermique 5, comportent essentiellement seulement des liaisons avec la bande transporteuse.l,ces liaisons étant établies à l'aide d'éléments intérieurs de fixation 8. The blades 2 have a sandwich structure and they have special outer plates 3 as well as inner plates 4 between which are placed layers of thermal insulation 5, the outer plates 3 and the inner plates 4 being rigidly connected with the layers d thermal insulation 5 using external fastening elements 6, which are arranged in the form of separable elements, such as screws. To avoid to a large extent the transmission of heat between the external plates 3 of the blades 2 and the conveyor belt 1, the internal plates 4, placed behind the thermal insulation layers 5, essentially comprise only connections with the conveyor belt. 1, these connections being established using interior fastening elements 8.

Pour limiter la transmission de chaleur entre la plaque extérieure 3 et la plaque intérieure 4,on peut placer sur les éléments extérieurs de fixation 6 des anneaux ou manchons d'espacement 7 les entourant et formés d!un matériau thermiquement isolant. To limit the heat transmission between the external plate 3 and the internal plate 4, it is possible to place on the external fixing elements 6 spacing rings or sleeves 7 surrounding them and formed from a thermally insulating material.

En outre,pour assurer une isolation thermique de la bande transporteuse,on peut disposer sur les éléments intérieurs de fixation 8 ou bien de chaque coté de la bande 1 des bagues isolantes 9,11 ainsi que des disques spéciaux d'évacuation de chaleur 10 qui sont pourvus d'un diamètre relativement grand. In addition, to ensure thermal insulation of the conveyor belt, it is possible to have on the internal fixing elements 8 or else on each side of the belt 1 insulating rings 9, 11 as well as special heat dissipation discs 10 which have a relatively large diameter.

Pour éviter un contact direct entre les éléments intérieurs de fixation 8 et la bande 1 ou bien les lames 2, il est prévu dans la zone supérieure et dans la zone inférieure de la bande transporteuse des disques de guidage 12 ayant de préférence une section droite en forme de L, constitués d tun matériau thermiquement isolant et servant à recevoir les éléments intérieurs de fixation 8. To avoid direct contact between the interior fastening elements 8 and the belt 1 or else the blades 2, there are provided in the upper zone and in the lower zone of the conveyor belt guide discs 12 preferably having a straight section in L-shaped, made of a thermally insulating material and used to receive the interior fixing elements 8.

Ces moyens permettent d'améliorer considérablement le refroidissement de la bande transporteuse ou bien des lames associées à celle-ci,également dans le cas d'une charge ou sollicitation élevée.  These means make it possible to considerably improve the cooling of the conveyor belt or else of the blades associated therewith, also in the case of a high load or stress.
