Variable Width Suction Nozzle for Screen Filter Debris Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen filters face a conflict between the need for large nozzle openings to evacuate large debris, effective scanning of the screen surface, and maintaining high suction speed for efficient cleaning.
Innovation Solution
A suction nozzle design with a longitudinally extending orifice that varies in width, featuring primary and secondary sections, allowing for efficient evacuation of large debris while maintaining high suction speed through symmetric or asymmetric configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the orifice of the suction nozzle is made large, then large debris can be evacuated effectively, but suction speed and cleaning efficiency decrease
Solution Approach 1:
The suction nozzle incorporates multiple orifices with different widths along its longitudinal extension. Primary sections have wider orifices for evacuating large debris, while secondary sections have narrower orifices for maintaining high suction speed. This local differentiation allows each section to optimize for its specific function, resolving the contradiction between debris evacuation capability and suction speed.
2Area of stationary object
If the suction nozzle is made wide, then effective scanning coverage increases, but suction speed decreases
Solution Approach 1:
The suction nozzle is segmented into multiple functional sections along its longitudinal extension, with each section containing orifices of specific widths. This segmentation allows the nozzle to provide wide scanning coverage through its overall width while maintaining high suction speed through the inclusion of narrower orifices in secondary sections, thus resolving the contradiction between scanning width and suction speed.
3Speed
If the orifice is made small, then suction speed increases, but large debris cannot be evacuated
Solution Approach 1:
The suction nozzle incorporates multiple orifices with different widths along its longitudinal extension. Primary sections have wider orifices for evacuating large debris, while secondary sections have narrower orifices for maintaining high suction speed. This local differentiation allows each section to optimize for its specific function, resolving the contradiction between debris evacuation capability and suction speed.
4Area of moving object
If the nozzle passage is made large, then large particles can pass through, but cleaning efficiency decreases
Solution Approach 1:
The suction nozzle is segmented into multiple functional sections along its longitudinal extension, with each section containing orifices of specific widths. This segmentation allows the nozzle to provide wide scanning coverage through its overall width while maintaining high suction speed through the inclusion of narrower orifices in secondary sections, thus resolving the contradiction between scanning width and suction speed.
