Title (EN) FILTER ELEMENT AND METHOD FOR MANUFACTURING THE FILTER ELEMENT
(FR) ÉLÉMENT DE FILTRATION ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) Magnetic elements (51) are provided inside a ceramic filter plate (32A) for creating a magnetic field. In an embodiment of the invention, magnetic elements (51) are located in cavities provided in partition walls (30) which define filtrate channels (33) between themselves. The filter plate can be used for increasing filtration capacity particularly in magnetite applications. The magnetic field causes an attractive force on the magnetic particles and thus increases the amount of material forming on the filter plate in a vacuum filter, such as a capillary action filter, conventional rotary vacuum filter or drum filter or capillary action drum filter.
(FR) L'invention concerne des éléments magnétiques (51) placés à l'intérieur d'une plaque de filtration céramique (32A) afin de créer un champ magnétique. Selon un mode de réalisation de l'invention, des éléments magnétiques (51) sont placés dans des cavités formées dans des parois de séparation (30) qui forment entre elles des canaux pour filtrat (33). La plaque de filtration peut être utilisée pour accroître la capacité de filtration, en particulier dans des applications de magnétite. Le champ magnétique génère une force d'attraction sur les particules magnétiques et augmente ainsi la quantité de matière se formant sur la plaque de filtration dans un filtre sous vide, tel qu'un filtre à action capillaire, un filtre sous vide rotatif conventionnel ou un filtre à tambour ou un filtre à tambour à action capillaire.
