Abstract

SE DESCRIBE UN PROCESO Y UN APARATO PARA LA PRODUCCION DE UNA MEZCLA DE POLIURETANO. EL APARATO COMPRENDE UN DISPOSITIVO MEZCLADOR (10, 50), DOTADO DE UNA CAMARA DE MEZCLA (11, 52), QUE DESEMBOCA EN UN CONDUCTO DE DESCARGA (12, 53). SE PROPORCIONAN UNAS TOBERAS SOPLANTES (42, 43) PARA GENERAR CHORROS DE AIRE QUE PERMITEN DESVIAR EL FLUJO DE LA MEZCLA DE POLIURETANO QUE SALE POR EL CONDUCTO DE DESCARGA (12, 53). EL APARATO DE MEZCLA AUTOLIMPIANTE COMPRENDE ADEMAS UN MIEMBRO ALARGADO DE LIMPIEZA (27), QUE SE MUEVE ALTERNATIVAMENTE DENTRO DEL CONDUCTO DE DESCARGA (12) Y LLEVA UN CANAL LONGITUDINAL (30) PARA ALIMENTAR UN MATERIAL DE REFUERZO FLUIDIFICADO, POR EJEMPLO FIBRAS DE REFUERZO (34) O UN MATERIAL DE REFUERZO EN FORMA DE POLVO O GRANULADO, QUE SE MEZCLARA CON LA MEZCLA DE POLIURETANO QUE FLUYE AL INTERIOR DEL CONDUCTO DE DESCARGA (12). EL CANAL DE ALIMENTACION DEL MATERIAL DE REFUERZO TERMINA EN EL EXTREMO FRONTAL DEL MIEMBRO DE LIMPIEZA (27), EN UN PUNTO EN EL QUE EL FLUJO DEL MATERIALDE REFUERZO CHOCA CON LA MEZCLA DE POLIURETANO QUE SALE DE LA CAMARA DE MEZCLA (11) EN CONDICIONES DE ELEVADA TURBULENCIA.
