Abstract

Un dispositivo de filtración a presión de materias sólidas contenidas en líquidos, que comprende, en combinación: un tambor provisto de canales radiales de llegada de líquido cargado a filtrar a partir de un distribuidor estanco sobre su árbol de rotación hasta desembocadura en la superficie del tambor, en las proximidades de las cuales están previstas válvulas, una tela que envuelve un primer sector del tambor y que se aparta en un segundo tambor complementario, según un trayecto en bucle que pasa sobre rodillos de cambio de sentido y una cadena de elementos alveolares que rodea a dicho primer sector por lo menos, el cual está envuelto por medios de aplicación estanca de dicha tela y de dichos elementos alveolares sobre dicho tambor, dispositivo caracterizado porque estos medios son puestos en acción durante los periodos de admisión con válvulas abiertas de líquido cargado, al paso que el tambor, la cadena y la tela están inmóviles, y relajados al cierre de dichas válvulas al paso que el tambor y la tela al menos son puestos en movimiento para hacerlos pasar frente a un puesto de rascado por lo menos de los residuos sólidos de las tortas de filtración.
