Abstract

Patente de Invenção: <B>''MEIO DE FILTRAGEM PARA A SEPARAçãO DE SóLIDO/LìQUIDO''<D>. Um meio de filtragem (1) serve, por exemplo, no caso de um filtro de sedimentação, para a formação de um bolo de filtragem. Uma base de sedimentação desse tipo é contituída, eventualmente, de um material metálico, e apresenta um grande número de aberturas (3). Para o aperfeiçoamento da sedimentação prévia, a base de sedimentação é formada de uma chapa (2) ou de uma folha, na qual, através da produção de uma grade de estiramento, são feitas aberturas (3), e são moldadas como fendas com uma largura de fenda (B) predeterminda, sendo que ocorre uma deformação plástica inversa da grade de estiramento, em conseq³ência da atuação mecânica e com isso, é produzida a largura de fenda definida. As aberturas (3) apresentam um alargamento ligeiramento cónico na direção de passagem.
