Abstract

La présente invention se rapporte à une structure individuelle d'extrusion d'un dispositif d'extrusion pour combustible solide du type filière à roue, et plus particulièrement à une structure individuelle d'extrusion d'un dispositif d'extrusion pour combustible solide du type filière à roue qui peut améliorer le travail d'entretien et la productivité et qui peut réduire les coûts d'entretien grâce à un changement et à un contrôle rapides et simples des composants abrasés lors d'un processus d'extrusion destiné à presser et à extruder des déchets afin de former un combustible solide. La structure individuelle d'extrusion du dispositif d'extrusion pour combustible solide du type à filière à roue de la présente invention comprend : une roue excentrée qui tourne par la puissance qui lui est appliquée de manière à effectuer une opération destinée à presser les déchets; et une filière d'évacuation agencée le long d'une voie circulaire de la roue excentrée. La filière d'évacuation comprend : une pluralité de premières filières d'évacuation destinées à évacuer les déchets par la pression de la roue excentrée; et une pluralité de secondes filières d'évacuation agencées autour des premières filières d'évacuation pour extruder et pour évacuer les déchets, la pluralité de premières filières d'extrusion étant constituées d'une structure dans laquelle une rainure d'extrusion d'un côté entrée est formée le long d'une voie de déplacement de la roue excentrée dans une circonférence intérieure d'un corps en forme d'arc formé dans une plage d'angle pouvant former la voie circulaire lors de leur assemblage l'un avec l'autre et dans laquelle une pluralité de trous de liaison sont formés vers une circonférence extérieure de la rainure d'extrusion du côté entrée en vue d'une liaison à la rainure d'extrusion du côté entrée, et les secondes filières d'extrusion étant agencées autour d'une circonférence extérieure de l'une des premières filières d'extrusion et chacune des secondes filières d'extrusion étant constituée d'une structure comportant une rainure d'extrusion d'un côté évacuation pour extruder et pour évacuer les déchets par les trous de liaison.
