Title (EN) APPARATUS FOR PRESSING LIQUID OUT OF MATERIAL CONTAINING LIQUID
(FR) APPAREIL POUR EXTRAIRE UN LIQUIDE D"UNE MATIERE
Abstract: front page image
(EN)An apparatus for pressing liquid out of suspensions containing liquid, comprising a screw feeder (5) adapted to feed the suspensions towards a dewatering zone (2) in which there are disposed two converging endless filter members (20, 21) adapted to be driven round a pair of back and front breaking rollers (18a, 18b). The pressing angle ((Alpha)) between the filter members can be varied as can the speed of the filter members in relation to the material which is fed forwards in order to achieve an optimum flow resistance for each suspension. In certain cases, this can be very high. A worm wheel (13) is provided to prevent material from retreating in the screw thread (11). According to one form of embodiment, two or more dewatering zones are disposed in series one after the other, thus further increasing the possibilities for achieving optimum dewatering conditions.
(FR)Un appareil servant a extraire un liquide d"une matiere en suspension comprend un dispositif d"alimentation (5) prevu pour alimenter en suspensions une zone d"assechement (2) dans laquelle sont disposes deux dispositifs convergents de filtration sans fin (20, 21) entraines par une paire de cylindres a l"avant et a l"arriere, (18a, 18b). L"angle de compression ((Alpha)) entre les dispositifs de filtration peut varier ainsi que la vitesse des filtres, selon la matiere, afin de provoquer une resistance maximum a l"ecoulement des suspensions. Dans certains cas, cette resistance peut etre tres elevee. Une vis sans fin (13) est prevue pour empecher le retrait de la matiere dans les filets de la vis (11). Selon une forme d"execution, deux zones d"assechement ou plus sont disposees en series l"une apres l"autre, cela dans le but d"obtenir des conditions d"assechement optimales.
