DescriptionDescription
L'invention concerne un entonnoir de chargement, en particulier pour le chargement de hauts-fourneaux. Les entonnoirs de chargement sont très répandus dans l'industrie et ils servent au chargement d'installations de toutes sortes avec les matériaux devant être traités par ces installations. Dans le cas des hauts-fourneaux par exemple, I'ensemble du chargement se The invention relates to a loading funnel, in particular for loading blast furnaces. Loading funnels are widely used in the industry and are used for loading facilities of all kinds with the materials to be processed by these facilities. In the case of blast furnaces for example, the entire load is
fait à travers un entonnoir de chargement situé dans la partie supérieure du haut- made through a loading funnel located at the top of the top
fourneau. De même dans les exploitations minières, les entonnoirs de chargement sont furnace. Similarly in mining operations, the loading funnels are
fréquemment utilisés.frequently used.
Les matériaux passant à travers l'entonnoir de chargement étant souvent extrêmement abrasifs, même les entonnoirs de chargement en acier très résistant connus Materials passing through the loading funnel are often extremely abrasive, even known heavy-duty steel loading funnels
s'usent relativement rapidement et doivent être démontés et remis en état ou remplacés. wear out relatively quickly and must be disassembled and reconditioned or replaced.
L'installation ne peut pas être chargée durant cette opération de démontage, ce qui est un The installation cannot be loaded during this disassembly operation, which is a
inconvénient important en raison des coûts d'exploitation extrêmement élevés. significant disadvantage due to the extremely high operating costs.
La durée de vie des entonnoirs de chargement connus ne s'élevant qu'à quelques semaines, I'objectif de l'invention est de prolonger la durée de vie des entonnoirs de As the lifespan of known loading funnels is only a few weeks, the objective of the invention is to extend the lifespan of loading funnels.
chargement et ainsi de diminuer les coûts d'exploitation. loading and thus lower operating costs.
Cet objectif est atteint en prévoyant un dispositif antiusure destiné à être inséré dans l'entonnoir de chargement. Le dispositif antiusure protège l'entonnoir de chargement This objective is achieved by providing an antiwear device intended to be inserted into the loading funnel. Anti-wear device protects the loading funnel
et il peut de plus être remplacé relativement rapidement par un autre dispositif antiusure. and it can also be replaced relatively quickly by another antiwear device.
La réduction de la durée de démontage et la suppression de la remise en état de l'entonnoir de chargement ou la prolongation conséquente de sa durée de vie permettent The reduction of the disassembly time and the elimination of the repairing of the loading funnel or the consequent prolongation of its service life allow
une économie considérable des coûts d'exploitation. considerable savings in operating costs.
Dans un développement avantageux de l'invention, les contours extérieurs du dispositif antiusure correspondent pour l'essentiel aux contours intérieurs de l'entonnoir de chargement. En épousant les formes de l'entonnoir de chargement, le dispositif In an advantageous development of the invention, the external contours of the antiwear device essentially correspond to the internal contours of the loading funnel. By following the shapes of the loading funnel, the device
antiusure est soutenu de façon optimale. antiwear is optimally supported.
Il est conforme à l'invention que le dispositif antiusure soit constitué d'au moins un élastomère contenant des additifs céramiques. L'invention est basée sur le fait qu'un corps élastique placé à l'intérieur de l'entonnoir résiste mieux aux contraintes dues au passage du matériau qu'un corps dur. En ajoutant des particules céramiques, on réduit I'abrasion et on prolonge la durée de vie. Grâce à cette combinaison de matériaux, la durée de vie d'un tel dispositif antiusure peut être jusqu'à cinq fois plus longue que celle d'un entonnoir de chargement en acier très résistant, tandis que l'entonnoir de It is in accordance with the invention that the antiwear device consists of at least one elastomer containing ceramic additives. The invention is based on the fact that an elastic body placed inside the funnel resists the stresses due to the passage of the material better than a hard body. By adding ceramic particles, the abrasion is reduced and the service life is extended. Thanks to this combination of materials, the lifespan of such an antiwear device can be up to five times longer than that of a very resistant steel loading funnel, while the funnel of
chargement ainsi protégé n'a plus besoin d'être remis en état ou remplacé. protected cargo no longer needs to be reconditioned or replaced.
Dans une autre forme de réalisation de l'invention, I'élastomère est du polyuréthane. In another embodiment of the invention, the elastomer is polyurethane.
Il peut être également avantageux que l'élastomère soit du caoutchouc. It may also be advantageous if the elastomer is rubber.
Il est conforme à l'invention que les additifs céramiques soient constitués pour It is in accordance with the invention that the ceramic additives are formed to
I'essentiel d'oxyde d'aluminium.Essentially aluminum oxide.
Il rentre dans le cadre de l'invention que la granulométrie des additifs céramiques It is within the scope of the invention that the particle size of the ceramic additives
soit comprise entre 0 et 10 mm.is between 0 and 10 mm.
Dans une autre forme de réalisation de l'invention, le dispositif antiusure est muni d'anneaux de levage situés sur ses bords supérieurs. Ceci facilite le dégagement du In another embodiment of the invention, the antiwear device is provided with lifting rings situated on its upper edges. This facilitates the release of the
dispositif antiusure de l'entonnoir de chargement. anti-wear device on the loading funnel.
Enfin, le dispositif antiusure destiné à être introduit dans l'entonnoir de chargement Finally, the antiwear device intended to be introduced into the loading funnel
tel que décrit précédemment fait également partie de l'invention. as described above is also part of the invention.
Un exemple de réalisation de l'invention est décrit ci-dessous à l'aide des figures annexées. La figure 1 montre un dispositif antiusure conforme à l'invention, La figure 2 montre un entonnoir de chargement correspondant; La figure 3 montre un entonnoir de chargement muni d'un dispositif antiusure An exemplary embodiment of the invention is described below with the aid of the appended figures. Figure 1 shows an antiwear device according to the invention, Figure 2 shows a corresponding loading funnel; Figure 3 shows a loading funnel fitted with an antiwear device
conforme à l'invention.according to the invention.
Comme le montrent les figures 1 et 2, la forme du dispositif antiusure (1) correspond pour l'essentiel à la forme de l'entonnoir de chargement (2), de sorte que le dispositif antiusure (1) épouse les formes de l'entonnoir de chargement (2). Il présente ainsi des parois formant un cône dirigé vers le bas qui touchent les parois de l'entonnoir de chargement (2). Le dispositif antiusure (1) conforme à l'invention se compose de préférence d'un matériau élastomère tel que du polyuréthane dans lequel sont5 incorporées des particules céramiques, par exemple de la céramique d'oxyde d'aluminium, ayant une granulométrie comprise entre 0 (poussières) et 10 mm. Sur ses As shown in Figures 1 and 2, the shape of the wear device (1) essentially corresponds to the shape of the loading funnel (2), so that the wear device (1) follows the shapes of the loading funnel (2). It thus has walls forming a cone directed downwards which touch the walls of the loading funnel (2). The antiwear device (1) according to the invention preferably consists of an elastomeric material such as polyurethane in which are incorporated ceramic particles, for example aluminum oxide ceramic, having a particle size between 0 (dust) and 10 mm. On his
bords supérieurs, il est avantageux de positionner des anneaux de levage (3) afin de faciliter l'échange des dispositifs antiusure (1). upper edges, it is advantageous to position lifting rings (3) in order to facilitate the exchange of the antiwear devices (1).
La figure 3 montre comment le dispositif antiusure (1) est positionné dans l'entonnoir de chargement (2). Il s'étend au moins sur la partie de l'entonnoir de chargement (2) sur laquelle le matériau à charger serait passé si un dispositif antiusure (1) n'avait pas été introduit. Bien que le dispositif antiusure (1) soit contigu à l'entonnoir de chargement (2), il peut facilement être dégagé de ce dernier grâce aux anneaux de Figure 3 shows how the antiwear device (1) is positioned in the loading funnel (2). It extends at least over the part of the loading funnel (2) over which the material to be loaded would have passed if an antiwear device (1) had not been introduced. Although the anti-wear device (1) is adjacent to the loading funnel (2), it can easily be removed from the latter thanks to the rings of
