Title
(EN) SELF-CLEANING FILTER FOR FILTERING LIQUIDS AND GASES
(FR) FILTRE AUTO-NETTOYANT POUR FILTRER DES LIQUIDES ET DES GAZ
Abstract
(EN)
A filter for filtering of a fluid, including a housing (1) having an inlet port (10) for the fluid to be filtered, an outlet port (12) for filtered fluid and an outlet port (11) for reject. In a body (14) arranged in the housing to be rotatable between at least two positions of rotation, there are at least two intercommunicating flow channels of which at least a first (16a, 16b) is provided with a filtering means (19a) through which filtering takes place in a first rotational position, wherein one end (16a) of the first flow channel communicates with the inlet port (10), and through which backwash takes place in the second rotational position, wherein said end (16a) of the first flow channel communicates with the outlet port (11) for reject. The first flow channel (16a, 16b) is provided with a filtering means (19a, 19b) at each end. A second (17) of the at least two flow channels connects to the first (17) flow channel between the filtering means (19a, 19b) and is in constant connection with the outlet port (12) for filtered fluid. The outlet port (11) for reject is provided with a shutting means (23) openable for backwashing.

L'invention concerne un filtre pour filtrer un fluide, qui comporte un boîtier (1) présentant un orifice d'entrée (10) pour le fluide à filtrer, un orifice de sortie (12) pour le fluide filtré et un orifice de sortie (11) pour le rejet. Dans un corps (14) placé dans le boîtier de sorte qu'il soit rotatif entre au moins deux positions de rotation, au moins deux canaux d'écoulement communiquant entre eux dont au moins un premier (16a, 16b) est doté d'un moyen de filtrage (19a) dans lequel le filtrage s'effectue dans une première position de rotation, une extrémité (16a) du premier canal d'écoulement communiquant avec l'orifice d'entrée (10), et dans lequel le lavage à contre-courant s'effectue dans une seconde position de rotation, l'extrémité (16a) du premier canal d'écoulement communiquant avec l'orifice de sortie (11) pour le rejet. Le premier canal d'écoulement (16a, 16b) est doté d'un moyen de filtrage (19a, 19b) à chaque extrémité. Un second canal (17) parmi au moins deux canaux d'écoulement est relié au premier canal d'écoulement, entre le moyen de filtrage (19a, 19b), et est en communication constante avec l'orifice de sortie (12) pour le fluide filtré. L'orifice de sortie (11) pour le rejet est doté d'un moyen d'obturation (23) qui s'ouvre pour le lavage à contre-courant.
