Abstract

EL INYECTOR DE LA CELULA DE FLTACION, QUE MUESTRA UN TUBO MEZCLADOR QUE SE ZAMBULLE EN LA SUSPENSION PERPENDICULARMENTE, QUE SE CONECTA CON EL ASPIRADOR DE AIRE Y SE LLEVA CADA CELULA DE FLOTACION EN LA CANTIDAD TOTAL DE SUSPENSION, SE COLOCA LATERALMENTE CON RESPECTO AL EJE MEDIO PERPENDICULAR DEL CORTE TRANSVERSAL REDONDO DEL DEPOSITO CONTRA LA PARTE EN LA QUE SE ENCUENTRA LA APERTURA DE SALIDA DE ESPUMA Y LA APERTURA DE SALIDA DEL LIQUIDO. ASI EL TUBO MEZCLADOR (1) SE ZAMBULLE SOLO EN LA SUSPENSION DE FORMA QUE SU APERTURA DE SALIDA (DESEMBOCADURA 2) SE ENCUENTRA SOBRE LA ALTURA MEDIA DEL NIVEL DEL CANTO DE PASO (7) DEL CANAL DE SALIDA DE ESPUMA (8), CALCULADO DESDE EL FONDO DEL DEPOSITO. ASI SE PREVE PREFERENTEMENTE LA APERTURA DE SALIDA DEL LIQUIDO (9) EN LA PROSIMIDAD INMEDIATA DEL FONDO DE LA CAJA, CON LO QUE SE PRODUCE UN CANAL DE SALIDA (12) SOBRE LA CHAPA DE CUBIERTA (11) QUE SE EXTIENDE SOBRE LA LONGITUD DE LA CELULA DE FLOTACION, DONDE PENETRA EL LIQUIDO LIMPIO SOBRE UNA HENDIDURA SUPERIOR (14) Y UNA INFERIOR (13).
