Title (EN) AN ARRANGEMENT IN LIQUID FILTERS IN WHICH THE FILTRATE IS DIVIDED IN TWO FRACTIONS
(FR) DISPOSITIF PREVU DANS DES FILTRES A LIQUIDE DANS LESQUELS LE FILTRAT EST SEPARE EN DEUX FRACTIONS
Abstract: front page image
(EN)A liquid filter comprises a filter rotor (1) with filtering means (7) and a container (2) for the filtrate. The filtrate is divided in two fractions, a coarse pre-filtrated derived from that side, where the rotor dives into the liquid, and a clear filtrate derived from the opposite side. The pre-filtrate fraction is extracted from the filtrate space thereby that the filtrate at said side of the container is forced to pass through a number of openings (13) lying close to the liquid surface of the filtrate and leading to a pre-filtrate outlet (10), which openings are spaced apart relative to each other and distributed along the rotor.
(FR)Un filtre à liquide est constitué d'un rotor de filtrage (1) doté de moyens de filtrage (7) et d'un contenant (2) destiné à recevoir le filtrat. Ledit filtrat est séparé en deux fractions, soit un préfiltrat grossier provenant du côté duquel le rotor plonge dans le liquide, et un filtrat clarifié provenant du côte opposé. La fraction de préfiltrat est extraite de la zone du filtrat, le filtrat du côté correspondant du contenant passant dans plusieurs ouvertures (13) situées à proximité de la surface liquide du filtrat réparties le long du rotor selon un certain espacement, puis dans une sortie de préfiltrat (10).
