Abstract

Perfeccionamientos en mezcladores continuos, para mezclas de caucho, plásticos y similares del tipo de los que comprenden dos rotores que giran en sentido inverso dentro de una cámara de mezcla, provista de una boca de carga, por la cual se introducen materiales a mezclar, y de una boca de descarga de abertura regulable, por la cual sale la mezcla en forma de banda continua, estando los rotores y la cámara de mezcla divididos en dos zonas claramente diferenciadas que son la zona de alimentación y la zona de mezcla, de modo que en la zona de la boca de carga los rotores giran dentro de cámaras paralelas, intercomunicadas lateralmente, en la zona de alimentación los rotores giran dentro de cámaras cilíndricas, paralelas e independientes , y en la zona de mezcla los rotores giran dentro de cámaras paralelas, intercomunicadas lateralmente, caracterizados porque la zona de alimentación de cada rotor está dotada de un husillo de doble paso y doble filete, y la zona de mezclado de cada rotor estáprovista de seis palas, dos de las cuales , denominadas palas mezcladoras, están desplazadas circunferencialmente 180º , una respecto a la otra, son continuas, ocupan toda la longitud de la zona de mezclado, y están divididas en cuatro zonas, en la primera de las cuales, en correspondencia con la boca de descarga , las palas son paralelas al eje de los rotores, en tanto que en la segunda zona las palas están dispuestas helicoidalmente de manera que tienen tendencia a transportar el material hacia el centro de la zona de mezcla, en la tercera zona , que constituye la zona central de mezcla, las palas vuelven a ser paralelas al eje de los rotores, y en la cuarta zona las palas están otra vez dispuestas helicoidalmente de manera que tienen tendencia a transportar el material hacia el centro de la zona de mezcla, estando dichas dos palas mezcladoras provistas de un frente de ataque suave respecto a las superficies interiores de la cámara de modo que constituyen unas palas mezcladoras, que realizan la mezcla por laminación o cizallamiento del material entre sus crestas y la superficie interior de la cámara, estando dispuesta una zona de transición progresiva que enlaza de manera continua las palas mezcladoras con los filetes del husillo de la zona de alimentación
