Abstract

LA INVENCION SE REFIERE A UNA PLACA AGUJEREADA GRANULADA BAJO EL AGUA PARA UN EXTRUSIONADOR EN LA GRANULACION DE MATERIALES SINTETICOS TERMOPLASTICOS, DONDE SE DISPONE DE UNA SUPERFICIE FRONTAL DE LA PLACA DE TOBERAS BAJO EL AGUA PROVISTA CON UNA CAPA DE PROTECCION AL DESGASTE, RAYADA POR LAS CUCHILLAS DE GRANULACION. SE HA PREVISTO UN AISLAMIENTO TERMICO EN LA PLACA AGUJEREADA DE GRANULACION, DEBIENDO CONSEGUIRSE UN BUEN AISLAMIENTO AXIAL Y AL MISMO TIEMPO UNA DISTRIBUCION DE TEMPERATURA REGULAR EN DIRECCION RADIAL. PARA ELLO SE HA PREVISTO QUE ENTRE EL LADO SUPERIOR EXTERIOR DE LA PLACA (4) AGUJEREADA DE GRANULACION PROPIAMENTE DICHA Y LA CAPA (16) DE PROTECCION AL DESGASTE SE DISPONGA DE UNA CAPA (17) AISLANTE, DE MODO QUE LA CAPA (16) DE PROTECCION AL DESGASTE ESTE APOYADA CONTRA LA CAPA (17) AISLANTE CON JUEGO RADIAL Y SIN O CON PRESION REDUCIDA AXIAL.
