Abstract

Patente de Invenção: "PROCESSO E APARELHO PARA A PREPARAçãO DE PASTA DE PAPEL A PARTIR DE PAPéIS VELHOS". A invenção refere-se a um processo e a um equipamento que permitem unir em um só aparelho as funções de filtração, de descontaminação e de espessamento de pasta de papel, a partir de velhos papéis, assegurando a função complementar de clareamento dos filtrados. O aparelho (1) gira à grande velocidade. A pasta de papel é introduzida pelo centro do aparelho (2) e acionada à velocidade angular. A pasta é em seguida levada ao longo de uma grade (6) com orifícios de pequena dimensão, permitindo separar as fibras da maior parte da água. A pasta espessa é evacuada por bocais (8) de extração. A água é clareada na zona de clareamento (16) e reciclada. Os elementos sólidos separados das águas são extraídos pelos bocais (20) e reciclados ou eliminados segundo as aplicações. Versões mais completas do aparelho incluem as funções de fracionamento, de eliminação de tinta e de purificação da pasta com fendas ou orifícios.
