Description
Bande transporteuse
On sait que les bandes transporteuses de conception classique, comme, par exemple celles dont l'armature est en textile et dont les revêtements sont en un élastomère tel que le caoutchouc, ne résistent pas à des températures très supérieures à 1000 C.
Au-delà, revêtements et armatures sont très rapidement détériorés.
La présente invention vise à la réalisation d'une bande transporteuse capable de supporter des températures de l'ordre de 200 à 3000 C sans subir de dégradation notable et sans que ces excellentes caractéristiques touchant notamment à sa résistance et à sa souplesse tant longitudinale que transversale, soient altérées. Une telle bande peut trouver son utilisation partout où des matières chaudes doivent être transportées. On peut citer comme exemple les cimenteries, les installations d'agglomération de minerai.
La bande transporteuse selon la présente invention est caractérisée en ce qu'elle comporte au moins une nappe constituée d'un tissu comprenant des fibres de verre associées à de l'amiante.
Une forme d'exécution de l'objet de l'invention sera décrite à titre d'exemple, en se référant à la figure unique qui représente schématiquement une coupe longitudinale du tissu utilisé dans la bande.
Le tissu utilisé pèse 4,8 kg/m2 et a une épaisseur de 8 mm.
Les chaînes de force 1 ainsi que les trames de force 2 sont en fibres de verre.
Les éléments 3 de trame, considérablement plus volumineux que les éléments 2, sont en amiante.
Les fils de liage 4, disposés dans le sens de la chaîne sont en fibres de verre.
Ce tissu a été imprégné d'un vernis silicone fluide de façon que, après évaporation des solvants du ver nis, 2 kg de résine silicone soient déposés par m2 de tissu. Cette résine a la propriété d'adhérer aux matières organiques en l'occurrence l'amiante et la fibre de verre dont on n'a pas retiré l'ensimage.
Comme les éléments en amiante retiennent une quantité importante de vernis le taux d'imprégnation est relativement élevé.
L'ensemble présente d'excellentes caractéristiques tant sur le plan des qualités mécaniques que sur celui de la tenue à des températures élevées.
I1 va sans dire que d'autres mixtures d'imprégnation présentant des avantages équivalents pourraient être utilisées. Ainsi, on pourrait utiliser des mélanges à base d'élastomère résistant bien aux températures élevées, comme les élastomères fluorés, élastomères silicones ou de caoutchouc butyle.
La bande ainsi obtenue présente des caractéristiques de résistance mécanique, de souplesse longitudinale et transversale et d'agrafage équivalentes à celles des bandes classiques.
Un tissu où de l'amiante est associée à des fibres de verre peut également être utilisé pour constituer un écran de bande transporteuse.
Dans ce cas, il est avantageux de n'imprégner que la face supérieure du tissu, l'autre face étant destinée à adhérer sur une couche de mélange à base d'élastomère.
Un tel tissu peut également être utilisé pour constituer une carcasse comportant plusieurs nappes superposées.
Conveyor belt
It is known that the conveyor belts of conventional design, such as, for example, those whose reinforcement is made of textile and whose coverings are made of an elastomer such as rubber, do not withstand temperatures much higher than 1000 C.
Beyond that, coatings and reinforcements deteriorate very quickly.
The present invention aims to achieve a conveyor belt capable of withstanding temperatures of the order of 200 to 3000 C without undergoing significant degradation and without these excellent characteristics affecting in particular its strength and its flexibility, both longitudinal and transverse. , are altered. Such a belt can find its use wherever hot materials have to be transported. Mention may be made, as an example, of cement factories and ore agglomeration facilities.
The conveyor belt according to the present invention is characterized in that it comprises at least one sheet consisting of a fabric comprising glass fibers associated with asbestos.
An embodiment of the object of the invention will be described by way of example, with reference to the single figure which schematically represents a longitudinal section of the fabric used in the strip.
The fabric used weighs 4.8 kg / m2 and has a thickness of 8 mm.
The strings of strength 1 as well as the wefts of strength 2 are made of glass fibers.
The frame elements 3, considerably larger than the elements 2, are made of asbestos.
The binding yarns 4, arranged in the direction of the warp, are made of glass fibers.
This fabric was impregnated with a fluid silicone varnish so that, after evaporation of the solvents from the ver nis, 2 kg of silicone resin are deposited per m2 of fabric. This resin has the property of adhering to organic materials, in this case asbestos and fiberglass, the sizing of which has not been removed.
As the asbestos elements retain a large amount of varnish, the impregnation rate is relatively high.
The assembly has excellent characteristics both in terms of mechanical qualities and that of resistance to high temperatures.
It goes without saying that other impregnation mixtures having equivalent advantages could be used. Thus, it is possible to use mixtures based on elastomers which are resistant to high temperatures, such as fluoroelastomers, silicone elastomers or butyl rubber.
The strip thus obtained has characteristics of mechanical strength, of longitudinal and transverse flexibility and of stapling equivalent to those of conventional strips.
A fabric where asbestos is combined with glass fibers can also be used to form a conveyor belt screen.
In this case, it is advantageous to impregnate only the upper face of the fabric, the other face being intended to adhere to a layer of mixture based on elastomer.
Such a fabric can also be used to constitute a carcass comprising several superimposed plies.
