Abstract

EN UNA MAQUINA DE MOLDEO A PRESION (NO MOSTRADA) CON INYECCION DE NEBLINA DE LIQUIDO, EN LA QUE SE UTILIZAN BOQUILLAS DE ATOMIZACION (SE MUESTRA UNA DE ELLAS) CON UNA CAMARA DE REMOLINO (27) QUE SUMINISTRA LIQUIDO PULVERIZADO MEZCLADO CON EL AIRE A TRAVES DE UNOS ORIFICIOS DE SALIDA (28), LA BOQUILLA O BOQUILLAS DE AIRE ATOMIZADOR (21 A) ESTAN ALIMENTADAS ININTERRUMPIDAMENTE DE AIRE COMPRIMIDO A TRAVES DE UN CONDUCTO DE PRESION (29), MIENTRAS QUE LA BOQUILLA DE LIQUIDO (21) SOLAMENTE RECIBE LIQUIDO A PRESION A TRAVES DE UN CANAL DE LIQUIDO (30) Y DE UNA VALVULA ESCLAVA (31, 32, 33) CONTROLADA POR LA PRESION DEL LIQUIDO EN LOS PERIODOS, EN LOS QUE SE DESEE LA INYECCION DE LA NEBLINA LIQUIDA; LAS CARACTERISTICAS PRINCIPALES NUEVAS CONSISTEN EN UNA CAMARA DE REMOLINO (24) SITUADA POR DELANTE DE LA CAMARA DE REMOLINO (27) Y, EN QUE ENTRE ESTAS DOS CAMARAS DE REMOLINO SE FACILITA UNA SENDA DE CIRCULACION (25, 25 A, 26) QUE CONECTA ENTRE SI LAS DOS CAMARAS DE REMOLINO (24, 27) Y, A TRAVES DE CUYASENDA, EL LIQUIDO NEBLINOSO QUE SE HA FORMADO EN LA CAMARA REMOLINO (24) ES OBLIGADO A PASAR Y CAMBIAR SU DIRECCION Y VELOCIDAD DE CIRCULACION, AL MENOS UNA VEZ, REDUCIENDO DE ESTE MODO EL TAMAÑO DE LAS PEQUEÑAS GOTAS DE ROCIO LIQUIDO. CON ESTA DISPOSICION, ES POSIBLE LA FORMACION DE UNA NEBLINA LIQUIDA QUE POSEA UNAS GOTAS MAS UNIFORMES Y DE MENOR TAMAÑO Y DISMINUIR EL CONSUMO Y DESPERDICIO DE LIQUIDO, AL TIEMPO QUE SE GARANTIZA UNA BUENA LUBRICACION DE LAS PAREDES DEL MOLDE.
