Abstract

EN UN BASTIDOR DE HORNO (10) HAY COLOCADO UN ROTOR DE TRATAMIENTO (30) QUE PUEDE GIRAR ALREDEDOR DE UN EJE CENTRAL (A) CON LUGARES DE CARGA (36) PARA RECIBIR UNA CARGA DE PIEZAS. SE CONECTAN CAMARAS SECUNDARIAS (110, 110 '' ) AL BASTIDOR DEL HORNO (10) Y SE DISEÑAN DE TAL MANERA QUE CADA UNA PUEDA COGER UNA CARGA DE PIEZAS DEL ROTOR DE TRATAMIENTO O ENTREGAR UNA AL ROTOR. UN ROTOR DE ESCLUSAS (60), QUE TAMBIEN ESTA LOCALIZADO EN EL BASTIDOR DEL HORNO (10) Y QUE PUEDE GIRAR ALREDEDOR DE UN EJE CENTRAL (A), SE COMPONE DE AL MENOS DOS CAMARAS DE ESCLUSAS (64) QUE ESTAN COLOCADAS UNA ENFRENTE DE OTRA Y CON UN ANGULO EN RELACION CON EL EJE CENTRAL (A). LAS CAMARAS DE ESCLUSAS (64), PARA QUE PUEDAN COGER CADA UNA, UNA CARGA DE PIEZA O DAR UNA CARGA SE ABREN DE MANERA ALTERNANTE CERCA DEL BASTIDOR DEL HORNO (10), Y ENCIMA DE UNA DE LAS CAMARAS SECUNDARIAS (110, 110 '' ). PARA TRANSFERIR UNA CARGA DE PIEZAS ENTRE UNA DE D ICHAS CAMARAS (64, 110, 110 '' ) Y EL ROTOR DE TRATAMIENTO (30) SE DISPONEN DISPOSITIVOS DE TRANSFERENCIA (112), ESTANDO AL MENOS UNO DE ESTOS DISEÑADO DE TAL MANERA QUE TRANSFIERE CARGA DE PIEZAS ENTRE EL ROTOR DE ESCLUSAS (60) Y EL ROTOR DE TRATAMIENTO (30).
