Spray Nozzle With Perpendicular Air And Water Inlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray nozzles for cooling casting strands face challenges in achieving uniform cooling due to the mutual influence of air and water pressure or flow, leading to uneven cooling effects and water droplet accumulations.
Innovation Solution
The spray nozzle design features an air inlet with radially distributed air outlet holes at a 90° ± 15° angle to the mixing chamber's longitudinal axis and a transverse water inlet, ensuring minimal interaction between air and water flows, along with a cylindrical mixing chamber and a replaceable nozzle head for adaptable spray patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional spray nozzles are used with shared mixing chambers for air and water, then the device structure is simple, but the air flow and water pressure mutually influence each other causing uneven cooling and water droplet accumulations
Solution Approach 1:
The mixing chamber is segmented into separate air and water inlet regions with distinct inlet orientations. Air enters through a lateral inlet while water enters through a transverse inlet, creating spatially separated flow paths that prevent mutual interference while maintaining a unified chamber structure for efficient mixing.
2Device complexity
If the air inlet angle is close to the longitudinal axis, then the device structure is simple, but the spray pattern quality deteriorates
Solution Approach 1:
Different regions of the mixing chamber are assigned different inlet configurations optimized for their specific functions. The air inlet is positioned laterally at an angle to promote radial mixing, while the water inlet is positioned transversely near the tip to create a fountain effect. This local optimization of inlet angles and positions achieves superior spray pattern quality without excessive complexity.

AI summary
Spray nozzle device comprises a mixing chamber (2) which acts as a diffuser and has a mixing body (1). The mixing chamber is provided with an air inlet (3), a water inlet (4), and a nozzle outlet (5) oriented approximately in alignment with the air inlet through which an air or water mixture exits. The air inlet comprises a region projecting in the mixing chamber, and at least one air outlet hole, which is perpendicular to the longitudinal axis of the mixing chamber. The water enters near the tip through at least one water outlet hole, which is oriented perpendicular to the longitudinal axis.
