Abstract

EL DISPOSITIVO PARA LA SEPARACION DE AIRE DE SUSPENSIONES FIBROSAS DE INSTALACIONES DE FLOTACION QUE ESTAN MEZCLADAS FUERTEMENTE CON AIRE Y ESPUMA SON, O MEJOR DICHO, UNA MEZCLA DE LIQUIDOS Y ESPUMA REPRESENTADAS, PRESENTA UN HIDROCICLON (1), CUYA ABERTURA DE ENTRADA (4) PARA EL QUE EL LIQUIDO CARGADO CON AIRE, O MEJOR DICHO, LA MEZCLA, ESTA COLOCADA AL MENOS 2,5 METROS DEBAJO DE LA ABERTURA DE SALIDA DEL DISPOSITIVO DE FLOTACION. EL CAMPO DE SEPARACION (3) DEL HIDROCICLON ES UN CUERPO DELGADO, EN FORMA DE CONO TRUNCADO, EN CUYOS FINALES EN PUNTA DELGADOS SE EXTRAE EL LIQUIDO DESINFLADO. POR ELLO, UNA CONTRAPRESION ES MANTENIDA EN ESTA ABERTURA DE SALIDA, DE FORMA QUE LA ABERTURA DE ENTRADA SEA DESTECHADA PLENAMENTE DEL REMOLINO DEL LIQUIDO, DE MODO QUE PERMANEZCA UNA ENTRADA TRANSVERSAL PARA LA ESPUMA BASTANTE LIBRE. POR ENCIMA DEL CAMPO DE ENTRADA (2) DEL HIDROCICLON ESTA COLOCADO UN DESTRUCTOR DE ESPUMA MECANICO CON UN ROTOR (10), QUE PRESENTA UNA RUEDA MOTRIZ, QUE ESTA PROVISTA CON UN SISTEMA DE ALABES RADIAL. UN CODO DE EMPALME DE ASPIRACION EN FORMA DE TOLVA CONDUCE LA MEZCLA DE AIRE-ESPUMA A LA RUEDA MOTRIZ.
