Abstract

1/1 resumo ”um aparelho de filtro de tambor“ a presente invenção se refere a um aparelho (10) compreendendo um tambor cilíndrico (20) suportado com uma estrutura de aro (21, 22) sobre um eixo rotacionável (25). uma superfície externa do tambor cilíndrico (20) compreende um número de placas de filtro (23) formando uma superfície de filtro cilíndrica. em concordância com a presente invenção, cada placa de filtro (23) é atada através de pelo menos três pontos de fixação (p1, p2, p3) para a estrutura de aro (21, 22). um primeiro recesso (46) se estende para a placa de filtro (23) e um flange de fixação (110) é posicionado pelo menos parcialmente no primeiro recesso (46). um membro de fixação longitudinal (120) é atado a partir de uma primeira porção de extremidade (121) para o flange de fixação (110) e forma uma segunda porção de extremidade (122) para a estrutura de aro (21, 22). pelo menos um recurso de fixação de encaixe (de estalido) (140) é posicionado no flange de fixação (110) ou na estrutura de aro (21, 22) ou em ambos. a placa de filtro (23) é montada sobre o tambor cilíndrico (20) por pressionamento da placa de filtro (23) radialmente para o tambor cilíndrico (20) de maneira tal que o recurso de fixação de encaixe (140) bloqueia a placa de filtro (23) para a estrutura de aro (21, 22) do tambor cilíndrico (20). a superfície externa da placa de filtro (23) irá ser ininterrupta, o que conduz para uma maior área de filtro efetiva na placa de filtro (23).1/1 summary a drum filter apparatus the present invention relates to an apparatus (10) comprising a cylindrical drum (20) supported with a frame structure (21, 22) on a rotatable shaft (25). an outer surface of the cylindrical drum (20) comprises a number of filter plates (23) forming a cylindrical filter surface. in accordance with the present invention, each filter plate (23) is attached through at least three attachment points (p1, p2, p3) to the frame structure (21, 22). a first recess (46) extends into the filter plate (23) and a mounting flange (110) is positioned at least partially in the first recess (46). a longitudinal fastening member (120) is attached from a first end portion (121) to the fastening flange (110) and forms a second end portion (122) for the frame structure (21, 22). at least one snap-on (snap) fastening feature (140) is positioned on the fastening flange (110) or the rim structure (21, 22) or both. the filter plate (23) is mounted onto the cylindrical barrel (20) by pressing the filter plate (23) radially into the cylindrical barrel (20) in such a way that the snap-on fastening feature (140) locks the filter plate (23) filter (23) to the rim structure (21, 22) of the cylindrical drum (20). the outer surface of the filter plate (23) will be unbroken, which leads to a greater effective filter area on the filter plate (23).
