Abstract

"SEPARADOR POR PRESSãO PARA FILTRAR UMA SUSPENSãO DE MATERIAL FIBROSO". A presente invenção se refere a um separador por pressão que apresenta um cesto de filtragem (1) , com cujo auxílio componentes indesejados, especialmente materiais estorvantes, são separados de uma suspensão de material fibroso (S) alimentada por meio de uma câmara de admissão (4) . O entupimento do cesto de filtragem (1) é impedido por meio de um limpador de filtros (7), que apresenta um elemento rotor (8) com elementos limpadores (7). O limpador de filtros (7) é acionado passando pela câmara de admissão (4). O elemento rotor (8) é dotado de um ressalto (11) que se projeta para dentro da câmara de admissão, especificamente para manter os materiais estorvantes longe da unidade de vedação (18).
