Abstract

UN APARATO DE TRATAMIENTO TERMICO QUE TIENE UN HORNO DE TRATAMIENTO TERMICO EN EL CUAL SE INTRODUCEN UN GAS DE HIDROCARBURO Y UN GAS DE OXIDACION, EN DONDE UNA APERTURA DE SALIDA DE UNA VALVULA (30) A TRAVES DE LA CUAL UN IMPULSOR (27) PARA IMPULSAR UNA PIEZA A TRATAR TERMICAMENTE EN EL HORNO DE TRATAMIENTO TERMICO ES MOVIBLE ESTA HERMETICAMENTE CONECTADO A UN PUERTO DE INSERCION DEL IMPULSOR FORMADO EN UNA PARED (28) DEL HORNO DE TRATAMIENTO TERMICO, Y UNA CAJA DE CIERRE (31) ESTA CONECTADA HERMETICAMENTE A UNA APERTURA DE ENTRADA DE LA VALVULA (309), EL IMPULSOR (27) SIENDO MOVIL HERMETICAMENTE A TRAVES DE LA CAJA DE CIERRE (31). UNA PUERTA ELEVADORA (4) PARA ABRIR Y CERRAR EL HORNO DE TRATAMIENTO TERMICO TIENE UN PASADOR GUIA (32) PROYECTADO A PARTIR DE LA MISMA, Y UN SEGURO (35) QUE TIENE UNA SUPERFICIE DE GANCHO SUPERIOR (33) PARA RECIBIR EL PASADOR GUIA (32) EN EL MISMO, EL SEGURO (35) ESTANDO PIVOTALMENTE SOPORTADO PARA QUE CUANDO LA PUERTA ELEVADORA (4) SEA BAJADA, LA PUERTA ELEVADORA (4) SEA MOVIDA POR EL SEGURO (35) HACIA UNA SUPERFICIE DE CIERRE DE LA APERTURA DEL HORNO DE TRATAMIENTO TERMICO. UNA RANURA GUIA (40) PARA GUIAR UN PASADOR (39) DE UNA PUERTA ELEVADORA (4) EN LA DIRECCION VERTICAL ES CURVADA EN LA PORCION INFERIOR DE LA MISMA HACIA UNA SUPERFICIE DE CIERRE DE LA APERTURA DEL HORNO DE TRATAMIENTO TERMICO. HAY PROVISTO UNA EMPAQUETADURA DE CIERRE (41) EN UNA SUPERFICIE DE CIERRE DE UNA APERTURA DEL HORNO DE TRATAMIENTO TERMICO, Y UN CONDUCTO DE REFRIGERACION (42) ESTA PROVISTO JUNTO A LA EMPAQUETADURA DE CIERRE (41).
