Abstract

QUE COMPRENDE: A) UNA SUSPENSION CONTENIENDO SOLIDOS Y LIQUIDOS, QUE FORMA UNA TORTA DE FILTRO SOBRE LA SUPERFICIE DEL MEDIO FILTRANTE; B) UNA TORTA DE FILTRO, LA CUAL ES MOVIDA CON RELACION AL OSCILADOR; C) UN OSCILADOR ULTRASONICO HECHO DE UN MATERIAL PIEZOELECTRICO O MAGNETOESTRICTIVO, EL CUAL ES COLOCADO EN RELACION UNO A UNO, CON DICHA TORTA DE FILTRO. DICHO OSCILADOR Y DICHA TORTA DE FILTRO SON CONSERVADOS INAMOVIBLES UNO RESPECTO AL OTRO, MIENTRAS EXISTA UN CONTACTO MECANICO ENTRE AMBOS, GENERANDO UN CAMPO ACUSTICO. DICHO CAMPO ACUSTICO TIENE UNA FRECUENCIA DE OSCILACION QUE ESTA EN EL RANGO DE 20 A 60 KHZ. ADEMAS DICHO OSCILADOR TIENE CONECTADO UN ELEMENTO ESTRUCTURAL, EL CUAL ES MOVIDO CON RELACION A DICHA TORTA
