Abstract

SISTEMA DE SUMINISTRO DE SILICIO. UN APARATO PARA SUMINISTRAR PARTICULAS DE SILICIO DE DIVERSOS TAMAÑOS Y FORMAS A UN BAÑO DE SILICIO FUNDIDO CONTENIDO EN UN CRISOL SITUADO EN UN HORNO A PARTIR DEL CUAL SE EXTRAE UNA CINTA DE SILICIO MONOCRISTALINO EN FORMA DE HOJA DENDRITICA, RECIBE LAS PARTICULAS DE SILICIO A PARTIR DE UN DEPOSITO A TRAVES DE UN TUBO DE SUMINISTRO (32) CONECTADO CON UNA ENVOLTURA (36) QUE CONTIENE UN TORNILLO SIN FIN QUE ESTA CONSTITUIDO POR UNA MULTITUD DE CERDAS NO METALICAS (48) QUE SE EXTIENDEN A PARTIR DE UN EJE GIRATORIO (46) DISPUESTO EN LA ENVOLTURA CILINDRICA NO METALICA. EL TORNILLO SIN FIN DESPLAZA LAS PARTICULAS DE SILICIO DESDE EL TUBO DE SUMINISTRO (32) A TRAVES DE LA ENVOLTURA (36) HASTA EL TUBO DE DESCARGA (50) A TRAVES DEL CUAL CAEN EN EL HORNO. TODAS LAS SUPERFICIES DEL APARATO DE SUMINISTRO NO SON METALICAS PARA GARANTIZAR QUE LAS PARTICULAS SE MANIPULARAN ESENCIALMENTE SIN ADQUIRIR CONTAMINANTES METALICOS.
