Abstract

ES BIEN SABIDO QUE LA TOMA DE MUESTRAS DE UN MATERIAL GRANULAR IMPURO POR MEDIO DE UNA LANZA TOMADORA DE MUESTRAS SIMPLE DE FORMA TUBULAR NO SUMINISTRA RESULTADOS REPRESENTATIVOS, UNA MEJORA SE HA OBTENIDO CONFORMANDO LA LANZA (2) CON UNA CAÑERIA (26) INTERIOR DE SUCCION Y UNA CAÑERIA (20) INSUFLADORA EXTERIOR, DICHAS CAÑERIAS SE ABREN UNA A LA OTRA EN EL EXTREMO DE LA LANZA A TRAVES DE UNA RANURA ANULAR (28) OBTENIENDOSE QUE EL MATERIAL QUE SE DEJA ENTRAR A TRAVES DE LA PUNTA DE LA LANZA ES TRANSPORTADO POR EL AIRE DE SUCCION HASTA UN SEPARADOR DE MATERIAL (12) SIN MOSTRAR NINGUN PROBLEMA ASOCIADO DE "EFECTO LIMPIADOR DE VACIO" FUERA DE LA BOCA DE LA LANZA. CON EL INVENTO SE SUMINISTRA UN PEQUEÑO AGUJERO (34) EN LA PARED DE LA CONEXION DE LA MANGUERA (14) ENTRE EL LADO DE LA PRESION DEL INSUFLADOR Y LA LANZA, A TRAVES DEL CUAL UN FLUJO DE AIRE FLOJO PUEDE SER INSUFLADO, POR DONDE UNA TOMA DE AIRE CORRESPONDIENTEMENTE SE PRODUCIRA A TRAVES DEL EXTREMO ABIERTO DE LA LANZA, Y MEDIANTE LO CUAL UNA MEJORA CONSIDERABLE DE LA EXACTITUD DE LA MUESTRA SE OBTIENE. PUEDE INCLUSO SER IMPORTANTE DISPONER UN AGUJERO SIMILAR, PERO MENOR, EN LA CONEXION DE SUCCION DE LA LANZA PARA REDUCIR EL VACIO EN ESTE LUGAR.
