Abstract

UN DISPOSITIVO NEUMATICO DE MEDICION PARA MEDIR MATERIALES PULVERIZADOS, POR EJEMPLO EN CONEXION CON LA ALIMENTACION DE OXIDO DE ALUMINIO Y FLUORURO DE ALUMINIO A UNA CELULA DE ELECTROLISIS, PARA LA PRODUCCION DE ALUMINIO, CONSISTIENDO EN UN CONTENEDOR (1), QUE TIENE FORMA DE UN CANAL O SIMILAR CERRADO, RELATIVAMENTE LARGO, CON UN ELEMENTO (4) FLUIDIZANTE, AJUSTADO EN LA BASE, PARA EL SUMINISTRO DE AIRE PARA LA FLUIDIZACION DEL MATERIAL, DESDE UN DEPOSITO QUE TIENE FORMA DE UN SILO O SIMILAR, Y UNA SALIDA (3) PARA MEDIR LA DESCARGA EL MATERIAL PROCEDENTE DE EL. EL AREA (10) POR DEBAJO DE LA ENTRADA (2) ESTA INACTIVA Y NO RECIBE AIRE DE FLUIDIZACION, MIENTRAS QUE SE SUMINISTRA AIRE INTERMITENTEMENTE AL ELEMENTO (4) DE FLUIDIZACION, QUE ESTA DISEÑADO PARA CUBRIR ESENCIALMENTE TODAS LAS PARTES S DE LA BASE.
