Title (EN) DEVICE FOR SEPARATING AND LIFTING SOLIDS FROM WASTE WATER
(FR) DISPOSITIF DE SÉPARATION ET DE LEVAGE DE SOLIDES À PARTIR D'EAUX USÉES
Abstract:
(EN) A device for separating and lifting solids from waste water has a stationary drum (2) provided with a first filter screen (6) and a screw conveyor (5). An auger shaft (8) has a lower portion (8a) located inside the stationary drum (2), which is partially surrounded by a second filter screen (10). The lower portion (8a) is connected to a cleaning apparatus (11) of the first filter screen (6) formed by a plurality of comb-holder arms (12) mounted on a cross shaped element (13). The comb-holder arms (12) are integral at the opposite end to an anti-skid ring (14) sliding in a sliding seat (27) integral with the support frame (1). Each comb-holder arm (12) has an elongated comb (15) facing the first filter screen (6) and in contact with it. The comb-holder arms (12) are connected to the auger shaft (8) by means of an epicyclic secondary gear (16).
(FR) Dispositif pour séparer et soulever des solides à partir d'eaux usées comprenant un tambour fixe (2) pourvu d'une première crépine (6) et d'un transporteur à vis (5). Un arbre (8) de tarière comporte une partie inférieure (8a) située à l'intérieur du tambour fixe (2), qui est partiellement entouré par une seconde crépine (10). La partie inférieure (8a) est reliée à un appareil de nettoyage (11) de la première crépine (6) formé par une pluralité de bras porte-peignes (12) montés sur un élément cruciforme (13). Les bras porte-peignes (12) sont intégrés au niveau de l'extrémité opposée à un anneau antidérapant (14) coulissant dans un siège de coulissement (27) solidaire du cadre de support (1). Chaque bras porte-peigne (12) possède un peigne allongé (15) faisant face à la première crépine (6) et en contact avec celle-ci. Les bras porte-peignes (12) sont reliés à l'arbre (8) de tarière au moyen d'un engrenage secondaire épicycloïdal (16).
