Abstract
Procedimiento de regulación automática en instalaciones de transporte neumático de materia pulverulenta, que comprende una columna de alimentación que contiene la materia, columna en cuyo pie se forma un talud de derrumbamiento, un recinto de expedición alimentado por la columna mencionada, provisto de una pared porosa de fluidización, de una conducción de alimentación de caudal elegido de gas sobrepresionado cuyo inyector conduce por encima de la pared porosa de fluidización y en eje del orificio de una conducción destinada al transporte neumático, así como una conducción de alimentación de gas de fluidización que conduce bajo la pared porosa de fluidización, caracterizado porque para provocar una disminución del ángulo del talud de derrumbamiento que permite llevar el pie de este talud en el flujo gaseoso, se fluidifica el material haciendo circular el gas a través de la pared porosa y la materia a transportar, porque para que este deslizamiento se produzca, se elige, para un caudal de materia deseado en la canalización de expedición, una presión de consigna Pf por debajo de la pared porosa, porque se establece por encima de la pared de presión Pc = Pf en el recinto de expedición de modo que a todo aumento de Pc más allá de Pf que tiende a aumentar el caudal de la materia pulverulenta, corresponde una disminución de la circulación gaseosa a la presión Pf a través de la pared porosa y la materia pulverulenta, mientras que a toda reducción de Pc por debajo de Pf que tiende a disminuir el caudal de la materia pulverulenta, corresponde un aumento de la circulación gaseosa a través de la pared porosa y la materia pulverulenta.
