  • a rotary drum with blades is used to shred the fibers. As the blades shred the fibers, the compressing action of the rotary drum extracts residue oil within the fibers.

Hence, the power supply was then taken from power station and turbine generator at the same time to solve the insufficiency of the power requirement to the drum.

Abstract

La présente invention porte sur un appareil pour déchiqueter et extraire des fibres longues à partir de résidus de palmier à huile. L'appareil comprend une enveloppe (10), deux tambours circulaires, espacés à la périphérie, disposés de façon coaxiale, à l'intérieur de l'enveloppe (10), le tambour interne (14) étant monté en vue d'une rotation à l'intérieur d'un tambour externe statique (12), le tambour externe (12) ayant une trémie d'entrée (18) pour introduire les résidus de palmier à huile, une sortie (20) pour les résidus de palmier à huile déchiquetés. L'appareil est en outre perfectionné avec au moins une lame dentée (16) qui est fixée de façon sûre à la paroi de l'enveloppe (10) à travers le tambour externe (12) avec une longueur prédéterminée qui définit un espace entre la lame (16) et un organe de découpe (24). Le tambour interne (14) est un tambour plein avec une pluralité d'organes de découpe (22) à ailettes étendues, disposés dans une configuration de chevron (28) qui tourne dans une zone cylindrique pour déchiqueter et découper les EFB dans une séquence de mouvements alternés. Une pluralité de pointes de trois ailettes étendues adjacentes (22) sont liées avec une pluralité de lames triangulaires connues comme étant des lames d'organe de découpe (24), les pointes des lames étant revêtues de carbure de tungstène. Les lames triangulaires sur la pointe des ailettes étendues forment une configuration de chevron (28). À mesure que le tambour interne (14) tourne, les ailettes étendues (22) passeront à travers les lames dentées (16) et cisailleront les résidus de palmier à huile en des résidus de palmier à huile partiellement vides et en fibres. Le tambour interne (14) réalise également la découpe et le déchiquetage des fibres de façon simultanée. Enfin, ce procédé convertit les EFB en fibres longues. Les longueurs des fibres longues sont entre 0,0508 m et 0,2032 m.
