Abstract

SE DESCRIBE UN APARATO (20) DE FILTRACION PARA LA EXTRACCION DE NUDOS DE UN FLUIDO QUE CONTIENE UN LODO DE FIBRAS Y NUDOS QUE HAN SIDO CONCENTRADOS DE UNA CORRIENTE DE PROCESADO DE PULPAS. UN CEDAZO RADIALMENTE SIMETRICO QUE ROTA SUMINISTRA UNA FILTRACION CENTRIFUGA PARA ACEPTAR UN LODO DE FIBRA MIENTRAS QUE UN TRANSPORTADOR ESPIRAL SUSPENDIDO INTEGRALMENTE CONECTADO AL ANTERIOR TRANSPORTE LOS NUDOS DE LA SUPERFICIE INTERNA DEL CEDAZO A UNA CAMARA DE DESCARGA DE NUDOS (34) LOCALIZADA AXIALMENTE POR ENCIMA DE LA CAMARA DE FILTRADO (62). ENCIMA DE LA CAMARA DE FILTRADO, PERO POR DEBAJO DEL NIVEL DEL LIQUIDO (65) EN LA CARCASA (14) SE SUMINISTRA UN LIQUIDO DE LAVADO LIBRE DE FIBRAS MEDIANTE UNA BOQUILLA ORIENTADA TANGENCIALMENTE (32) EN LA DIRECCION DE ROTACION DEL TRANSPORTADOR ESPIRAL AEREO PARA SOLTAR LAS FIBRAS DE LAS SUPERFICIES DE LOS NUDOS, PERMITIENDO QUE ESTAS PASEN POR EL CEDAZO. EL APARATO DE FILTRADO TAMBIEN SUMINISTRA FACILIDADES PARA LA EXTRACCION DE MATERIALES PESADOS, PARA MANTENER EL NIVEL DE CONTROL DEL LIQUIDO, PARA MINIMIZAR LA ENTRADA DE AIRE Y LA FORMACION DE ESPUMA Y PARA EVITAR LA OBSTRUCCION DE LAS ABERTURAS DEL CEDAZO Y LA DEL ORIFICIO DE SALIDA DE LOS NUDOS.
