Abstract
Dispositivo Neumático para controlar el flujo de sólidos granulares. El dispositivo neumático para controlar el flujo de sólidos granulares tiene como principal característica que es una válvula no mecánica (es decir, no tiene elementos móviles) que está basada en combinaciones de secciones tubulares verticales e inclinadas. Funciona con aire comprimido u otro gas de aireación de tal manera que se puede ejercer control sobre el flujo de sólido que pasa a su través, modificándolo dentro de un intervalo dado, e incluso cerrando totalmente el paso de sólido si interesa. El dispositivo va dotado de sistemas de control automático para regular el flujo del sólido y los caudales de aireación utilizados en la manipulación de dicho flujo y los utilizados en los ciclos de autolimpieza. Tiene aplicación en el manejo, dosificación y control del flujo de sólidos granulares de tolvas, silos, lechos móviles y lechos fluidizados.
