Abstract
"MéTODO E APARELHO PARA O ESPESSAMENTO DE SUSPENSõES DE FIBRA". A presente invenção refere-se ao espessamento de suspensões de polpa. Uma suspensão de polpa de baixa consistência é alimentada para um pré espessador (10) através de um conduto de entrada (18). Uma camada de polpa espessada, formada sobre uma superfície de filtro (22), é impulsionada ao longo da superfície de filtro por meio de membro de limpeza até a extremidade de descarga do pré espessador e é descarregada através da saída (20). O membro de limpeza compreende um eixo rotativo (30), sobre cujo eixo pelo menos uma rosca de parafuso é fixado de modo a deixar um espaço livre entre o eixo e a rosca de parafuso. Essencialmente, a polpa não espessada é deixada fluir através do aparelho por meio deste espaço.
