Abstract

Una bomba submarina de arena mejorada que comprende un motor submarino que tiene un eje de salida descendente en el que se monta un rodete, una caja de bomba que encierra dicho eje de salida, un agitador unido de forma fija a la extensión inferior de dicho eje de salida, consistiendo dicho agitador en un cono truncado y una pluralidad de álabes montados radialmente en la pared circunferencial de dicho cono truncado y una alcachofa de aspiración cilíndrica perforada colocada entre una entrada de aspiración de dicho rodete y dicho agitador de arena, estando dotada dicha alcachofa de aspiración de una chapa terminal en el extremo inferior en la misma en la que se forma una abertura circular, caracterizada por la mejora consistente en que los medios de separación. del flujo que separan el flujo de agitación y el flujo de aspiración se colocan en dicha abertura circular, dichos medios de separación del flujo se montan de forma integral y contigua en el extremo superior de dicho cono truncado dedicho agitador y dichos medios de separación del flujo tienen un diámetro exterior sustancialmente igual al diámetro interior de dicha abertura cilíndrica de dicha chapa terminal de dicha alcachofa de aspiración perforada.
