Abstract

<B>"APARELHO PARA FILTRAçãO DE LìQUIDOS"<D>. A invenção se refere a um aparelho para filtração de líquidos, que compreende um corpo vazado (1), que é rotativo em torno de um eixo horizontal (6). O líquido a ser filtrado é suprido dentro do interior do corpo vazado rotativo, onde o filtrado circula por gravidade através do material filtrante (2) do corpo vazado, dentro de um recipiente de filtrado (22). Um dispositivo de vedação (14), realiza a vedação entre uma parede estacionária circunferencial (13), que define uma câmara de suprimento de líquido (12) e uma parede circunferencial impermeável a líquido (8) do corpo vazado. Meios de parede (8, 20a) são dispostos para impedir que o vazamento de líquido não filtrado, que passa através do dispositivo de vedação, entre no recipiente de filtrado.
