Title
(EN) DEVICE FOR FILTERING LIQUID DRAWN IN BETWEEN TWO SUPERIMPOSED LAYERS OF FILTERING MEDIA
(FR) DISPOSITIF DE FILTRATION DE LIQUIDE ASPIRÉ ENTRE DEUX COUCHES SUPERPOSÉES DE MÉDIA FILTRANT
Abstract
(EN)
The present invention relates to a filtration device for a liquid, comprising:- at least two superimposed layers (4, 6) of filtering media which have weld lines (16, 18) together forming bands, the layers (4, 6) of filtering media having weld lines (16, 18) which are superimposed in such a manner that the weld lines (16, 18) of one layer (4, 6) form with the weld lines (18, 16) of the other layer (6, 4) a mesh in a view normal to the layers (4, 6) of filtering media, - a first external face (2) and a second external face (8) which are each at least locally produced from a material which is water-permeable, the layers (4, 6) of filtering media being arranged between the external faces (2, 8) and - an intake connector (10) which serves to draw in liquid through the filtration device.
(FR)
La présente invention a pour objet un dispositif de filtration pour un liquide comportant : - au moins deux couches (4, 6) superposées de média filtrant présentant des lignes de soudure (16, 18) formant entre elles des bandes, les couches (4, 6) de média filtrant présentant des lignes de soudure (16, 18) étant superposées de telle sorte que les lignes de soudure (16, 18) d'une couche (4, 6) forment avec les lignes de soudure (18, 16) de l'autre couche (6, 4) un maillage selon une vue normale aux couches (4, 6) de média filtrant, - une première face externe (2) et une seconde face externe (8) réalisées chacune au moins localement dans un matériau perméable à l'eau, les couches (4, 6) de média filtrant étant disposées entre les faces externes (2, 8), et - un connecteur d'aspiration (10) servant à l'aspiration de liquide à travers le dispositif de filtration.
