Abstract
Dispositivo extractor-dosificador para productos pulverulentos que comprende una tolva (3) y unos tornillos coaxiales (9/10) con pasos en sentido invertido, arrastrados en rotación dentro de un conducto cilíndrico (2b), cuyos tornillos están separados uno del otro por la pared de un tubo (2d) coaxial a los tornillo y al conducto, girando el tornillo (9) de diámetro más pequeño en el interior del tubo (2d), para transportar en este el producto en un sentido y el tornillo (10), de mayor diámetro que gira por fuera del mencionado tubo (2d) para transportar el producto en sentido opuesto, en el espacio delimitado entre el tubo (2d) y el conducto (2b), comprendiendo este en su periferia por lo menos un orificio (15) por el cual fluye el producto, caracterizado porque los mencionados tornillos (9/10) están hechos a partir de hilos enrrollados en espiral en forma de muelle, y porque el tubo (2d) dentro del cual va montado el tornillo (9) de diámetro más pequeño, llamado tornillo de extracción, comprende en su periferia y por el lado de la tolva (3), una abertura (2d2) de introducción del producto, delante de la cual se extienden al menos en parte los mencionados tornillos (9/10), cuyo producto, después de que ha atravesado el mencionado tubo (2d) se recupera mediante el tornillo (10) de mayor diámetro y se transporta en sentido inverso, y por fuera del tubo (2d), por el lado de la tolva (3) para ejercer una presión constante a la altura de la entrada, con el fin de evitar los efectos de bóveda por encima de la abertura de entrada (2d2) y hacer pasar simultáneamente el producto por un orificio (15) situado en la periferia del conducto (2b).
