Abstract

Un dispositivo de filtro para separar un material de partículas (19) de un flujo de plásticos que fluyen; el dispositivo comprende un miembro de cuerpo (10) que tiene al menos una cámara de filtro (18) y una recorrido del flujo (17, 18, 20, 23), que se extiende entre los lados de la entrada (12) y la salida (13). Una banda de filtro (11) se extiende transversalmente en la mencionada cámara de filtro (18), a través del recorrido del flujo, estando soportado por una placa posterior (31) que tiene un área perforada. Se proporciona un miembro valvular movible axialmente (21) que comprende un conducto del flujo (20, 22) para el material plástico, dentro de la cámara (18), y un actuador (24) para mover axialmente el miembro valvular (21) entre una posición avanzada y otra de tipo retraído en que el miembro valvular (21) conecta respectivamente y desconecta el paso del flujo (17, 18, 20, 23) desde los lados de la entrada (12) o la salida (13) del dispositivo, y para amordazar en forma estanca la banda del filtro (11) periféricamente alrededor del área perforada de la placa posterior (30).
