Abstract:
PROBLEM TO BE SOLVED: To provide an air assisted liquid spray nozzle assembly which is adapted for operation with substantially reduced air consumption and has particular utility in spraying a liquid coolant in continuous metal casting system. SOLUTION: A nozzle body includes a pre-atomizing unit having a relatively small-sized pressurized air inlet, a liquid impingement post 38 with a uniquely configured impingement face for enhancing liquid break down and for intermixing with the pressurized air stream from the air inlet, and an expansion chamber 25 configured to reduce eddy current that detract from efficient pre- atomization of the liquid. The spray nozzle further includes an elongated spray tip supporting barrel adapted for releasable mounting in a pre-atomizing head in a predetermined rotational orientation relative to its longitudinal axis for properly receiving and supporting its removable spray tip.

Abstract:
A full cone liquid spray nozzle is provided. The spray nozzle includes a nozzle body having a discharge orifice at a downstream end and an inlet at an upstream end for connection to a liquid supply. A liquid flow passageway extends through the nozzle body communicating between the inlet and the discharge orifice. A vane is disposed in the liquid flow passageway upstream of the discharge orifice. The vane has a plurality of V-shaped passageways therein. Each V-shaped passageway extends inward at an angle with respect to a longitudinal axis of the vane between an upstream face and downstream face of the vane. A whirl and mixing chamber defined by the liquid flow passageway is arranged between the vane and the discharge orifice.

Abstract:
Un montaje de boquilla para rociar asistida por aire, que tiene una particular utilidad en el rociado de fluidos refrigerantes en sistemas continuos de moldeo o vaciado metalico, que se adaptan para operacion con el consumo de aire substancialmente reducido. El cuerpo de la boquilla incluye una unidad de pre-atomizacion que tiene una entrada de aire presurizado con un tamano relativamente pequeno, un poste de choque del liquido con una cara de choque configurada de manera unica para mejorar el abatimiento del liquido y el intermezclado con una corriente de aire presurizado a partir de la entrada de aire, y una camara de expansion configurada para reducir las corrientes parasitas que se limitan la pre-atomizacion eficiente del liquido. La boquilla para rociar incluye un cilindro que soporta el extremo o punta para rociar alargada, adaptado para montarse de manera liberable en la cabeza de pre-atomizacion en una orientacion rotacional predeterminada con relacion a su eje longitudinal para recibir adecuadamente y soportar un extremo o punta de rocio removible.
