Nozzle With Tilted Side Passages For Uniform Filter Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzles used for cleaning filter elements, particularly cylindrical filters, often produce non-uniform fluid flows with insufficient momentum, leading to incomplete cleaning and are difficult to remove for maintenance or replacement.
Innovation Solution
A nozzle design featuring a hollow truncated cone with a central first nozzle opening and multiple tilted second openings on its lateral surface, creating a helical flow contour that stabilizes and constricts the fluid flow, allowing for increased momentum and targeted cleaning, along with a nozzle arrangement that allows for easy attachment and detachment from a supply line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional nozzle is used to direct fluid flow onto the filter element, then the nozzle structure is simple, but the fluid flow is not sufficiently uniform and the impulse is too low to clean the entire surface effectively
Solution Approach 1:
The nozzle is divided into multiple functional sections: a first nozzle section with a first passage for generating a core flow, and a second nozzle section with multiple second passages for generating outer flows. This segmentation allows each section to perform a specific function, creating a more effective overall flow pattern that maintains uniformity and impulse over a larger cleaning area.
Solution Approach 2:
Different regions of the nozzle are designed with different flow characteristics. The first passage produces a concentrated core flow with high impulse, while the multiple second passages produce distributed outer flows that expand the cleaning area. This local differentiation of flow qualities ensures both sufficient impulse and uniform coverage across the filter element surface.
2Reliability
If the nozzle is permanently mounted in the nozzle arrangement, then the mounting is secure, but the nozzle is difficult to remove for maintenance or replacement
Solution Approach 1:
The mounting system transitions from a permanent fixed connection to a dynamic, reversible connection. The nozzle can be securely mounted during operation but can also be easily removed when maintenance or replacement is needed. This dynamic mounting approach allows the system to adapt between operational security and maintenance accessibility requirements.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nozzle design ensures a stable, uniform fluid flow with increased momentum for effective cleaning over a larger area, while the modular arrangement facilitates easy handling and maintenance.
Implementation Method 1
the second passages each have a passage axis tilted with respect to a parallel axis parallel to a central axis of the nozzle for imposing a helical flow contour on the fluid flow
