Abstract There is disclosed a filter conveyor band or belt for a continuously operating filter press, preferably of the vertical type, which includes hingedly interconnected links having drainage grooves extending longitudinally of the link with the forward ends of the grooves being open and means being provided to close the rearward ends of the grooves. There are longitudinally extending ribs that separate the grooves with such ribs having forward ends that are inclined forwardly of and away from the top surface of the ribs. The means that close the rear ends of the grooves including a rear surface as regards the direction of movement that is inclined correspondingly to the inclination of the forward ends of the ribs so that such forward ends of the ribs of a trailing link cooperate with such rear surface of a preceding link to be in at least approximately adjoining relation with such rear surface when the band is straight and to define a gap which narrows in the direction away from the tops of the ribs when the band is curved.
A filter conveyor band for a continuously operating press including a plurality of hingedly interconnected links, each link comprising a body having drainage grooves extending in the direction of movement of the band, means closing the rear end of each groove, each groove being open at its forward end, ribs extending longitudinally of the body and separating said grooves, said ribs including a forward end, that is inclined forwardly of and away from the plane of the tops of said ribs, and the means closing the rear end of each groove having a rear surface as regards the direction of movement of said band that is inclined correspondingly to the inclination of the forward end of the said ribs whereby said forward ends of said ribs cooperate with said rear surface so as to at least approximately adjoin such rear surface when the band is in straight condition and to define a gap which narrows in a direction away from the tops of said ribs when the band is in curved condition.
