Abstract

SE DESCRIBE UN DISPOSITIVO PARA DESGASIFICADO DE MATERIAL SINTETICO TERMOPLASTICO, DISPONIENDO EL DISPOSITIVO DE UNA PRIMERA ZONA (11) DE TRANSPORTADOR DE TORNILLO SINFIN PARA LA ALIMENTACION DEL MATERIAL A SER TRATADO. EL MATERIAL SINTETICO TERMOPLASTICO FLUYE A PARTIR DE LA CARCASA (10) DE LA ZONA (11) DE TRANSPORTADOR DE TORNILLO SINFIN A TRAVES DE UN CANAL (15) DE CONEXION A UN FILTRO (16) Y A PARTIR DE AQUI A TRAVES DE UNA ABERTURA (17) DE ENTRADA A UNA CARCASA (18) DE UNA SEGUNDA ZONA (19) DE TRANSPORTE DE TORNILLO SINFIN QUE TRANSPORTA EL MATERIAL A UNA SALIDA (21). COLOCADA ENTRE LAS DOS ZONAS (11,19) DE TRANSPORTE DE TORNILLO SINFIN DE MISMO EJE, SE DISPONE DE UNA ZONA (26) DE SELLADO QUE PREVIENE LAS SITUACIONES EN LAS QUE EL FILTRO (16) SEA BAIPASEADO. DE FORMA INMEDIATA DESPUES DE LA ABERTURA (17) DE ENTRADA SE DISPONE DE UNA BARRERA (28) DEFLECTORA QUE FUERZA A LA CORRIENTE DE MATERIAL SINTETICO TERMOPLASTICO A UN PERFIL TUBULAR. LA BARRERA (28) DEFLECTORA PUEDE SER AJUSTADA RELATIVAMENTE CON RESPECTO A LA ABERTURA (17) DE ENTRADA EN LA DIRECCION LONGITUDINAL Y DISPONE DE UNA SECCION TRANSVERSAL QUE SE ESTRECHA DE FORMA CONICA HACIA LA SEGUNDA ZONA (19) DE TRANSPORTE DE TORNILLO SINFIN. ESTO ACORTA LA VIA DE VIBRACION DE LAS BURBUJAS DE GAS A PARTIR DEL MATERIAL SINTETICO TERMOPLASTICO Y FACILITA DE ESTA FORMA EL DESGASEADO A TRAVES DE LA ABERTURA (20) DE DESGASIFICACION.
