Solution Overview
Problem
Current atomizing nozzle designs rely on experience and lack a scientific approach to optimize outlet flow rates, leading to unstable performance and poor hydraulic efficiency, making it difficult to determine the cause of issues with non-uniform spraying and poor atomization.
Innovation Solution
A method to optimize the rotation angle of the outlet by measuring and adjusting the outlet clearance between the nozzle core and body, calculating the flow coefficient, and setting the outlet clearance to achieve a desired flow rate, using a threaded connection and reference/scale lines for precise adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the outlet flow rate is increased to improve spraying coverage, then the spraying coverage is improved, but the atomization effect deteriorates due to excessively big water droplets
Solution Approach 1:
The patent applies parameter changes by adjusting the outlet clearance parameter to control the outlet flow rate. By changing the clearance value between the nozzle core and nozzle body, the system achieves different flow rates that balance spraying coverage and atomization effect, resolving the contradiction between coverage area and droplet size control
2Manufacturing precision
If the outlet flow rate is decreased to improve atomization effect, then the atomization effect is improved, but the spraying coverage deteriorates due to non-uniform spraying
Solution Approach 1:
The patent uses parameter changes to adjust the outlet clearance to achieve an optimal flow rate that ensures uniform spraying across the coverage area while maintaining good atomization effect, preventing both insufficient and excessive flow conditions
3Measurement precision
If the outlet clearance is adjusted to control outlet flow rate, then the outlet flow rate is controlled, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The patent applies dynamics by making the outlet clearance adjustable through a movable nozzle core that can be rotated relative to the nozzle body. This dynamic adjustment mechanism allows the clearance to be changed without requiring complex additional components, achieving flow rate control with minimal increase in device complexity
Solution Approach 2:
The patent segments the nozzle into a nozzle core and a nozzle body that can be independently adjusted. The nozzle core can be rotated relative to the nozzle body to change the outlet clearance, allowing precise flow rate control through a simple rotational adjustment mechanism rather than a complex system
4Ease of manufacture
If the outlet structure parameters are set based on experience, then the design process is simple, but the optimization accuracy deteriorates due to inability to precisely control outlet flow rate
Solution Approach 1:
The patent introduces feedback by establishing a mathematical model that relates the outlet clearance to the outlet flow rate through the flow coefficient. This feedback mechanism allows the design process to move from experience-based estimation to calculation-based precision, where the flow rate can be accurately predicted and controlled based on the clearance parameter
