Abstract

PANTALLA DE CRIBA Y METODO DE FABRICACION. UNA PANTALLA PARA CRIBADO DE LAS PULPAS DE PAPEL Y SEPARACION DE LAS IMPUREZAS, ASTILLAS, MADERAS Y OTROS PRODUCTOS PRESENTANDO LAS APANTALLAS PLANAS Y CILINDRICAS UNA PLURALIDAD DE ABERTURAS CIEGAS (ES DECIR, ORIFICIOS O RANURAS) FORMADOS A TRAVES DE UNA PRIMERA CARA DE UNA PLACA DE ACERO Y EXTENDIENDOSE A UNA DISTANCIA PREDETERMINADA CERCA DE LA CARA OPUESTA. ABERTURAS DE TAMAÑO MAYOR SON FORMADAS A TRAVES DE LA PRIMERA CARA UTILIZANDO LAS ABERTURAS CIEGAS COMO ABERTUTAS PILOTO. LAS ABERTURAS DE MAYOR TAMAÑO SE EXTIENDEN EN EL INTERIOR DE LA PLACA CERCA DE LAS TERMINACIONES DE LAS ABERTURAS CIEGAS. EL METAL ES MAQUINADO DESDE LA CARA OPUESTA EN HILERAS PARALELAS DEFINIENDO RANURAS Y A UNA PROFUNDIDAD PARA NO CUBRIR LAS TERMINACIONES DE LAS ABERTURAS CIEGAS EN EL CUERPO DE LA PLACA SUMINISTRANDO POR TANTO ABERTURAS DE CRIBADO QUE SE EXTIENDEN A TRAVES DE LA PLACA. LOS NERVIOS (BARRAS) ENTRE LAS RANURAS PUEDEN SER DE SECCION TRANSVERSAL CUADRADA, OCON UNA CARA INCLINADA (ANGULADA) POR MECANIZACION.
