Fluid Filter Drum Motor Rotary Spray Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid filters with rotary spray arms suffer from reduced cleaning efficiency due to the simultaneous use of flushing medium for driving and cleaning, limited rotary movement to one direction, and a relatively small filter surface area compared to filter volume and size.
Innovation Solution
Incorporating a fluid-proof drum motor within the filter to drive a rotary spray arm, allowing for a more efficient cleaning mechanism with a slim structure that matches the filter's form, enabling reciprocating motion and increased filter surface utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pressurized water is used to drive the rotary spray arm, then the spray arm rotates continuously in one direction, but the cleaning efficiency is reduced because the flushing medium must simultaneously drive and clean
Solution Approach 1:
The drum motor uses the flushing medium itself to drive the spray arm rotation, making the system self-powered without requiring separate drive mechanisms. The flushing medium drives the drum motor which in turn rotates the spray arm, eliminating the need for external power sources while maintaining cleaning effectiveness
Solution Approach 2:
The drive function is extracted from the flushing medium's direct action on the spray arm and separated into a dedicated drum motor mechanism. This allows the flushing medium to focus on cleaning while the drum motor handles rotation, resolving the conflict between driving and cleaning functions
2Productivity
If the filter surface is made large to increase water intake, then the filter volume and size increase, but the cleaning coverage becomes insufficient relative to the filter surface area
Solution Approach 1:
The spray arm is made rotatable by the drum motor, transforming it from a static to a dynamic cleaning mechanism. This rotation allows a single spray arm to cover the entire filter surface area, maintaining effective cleaning coverage even as filter size increases to accommodate larger water intake capacity
3Volume of moving object
If a compact drive mechanism is used to save space within the filter, then the filter surface area available for water intake is reduced, but the cleaning mechanism becomes less effective
Solution Approach 1:
The drum motor is positioned centrally within the filter structure, with the spray arm mounted on its perimeter. This nested arrangement allows the drive mechanism to occupy minimal central space while the spray arm extends outward to cover the maximum filter surface area, optimizing both compactness and cleaning effectiveness
Applied Scientific Principles
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 solution enhances cleaning efficiency by ensuring the entire filter surface is available for water intake and providing a space-saving drive mechanism, allowing for various filter shapes and configurations, including stacked elements, which improves throughput and modular construction.
Implementation Method 1
arranging a fluid-proof drum motor within the filter for driving at least one spray arm
Implementation Method 2
The filter surface is continuously cleaned of dirt deposited on the outside of the filter surface, by the rotary spray arm conducting flushing water or pressurized air fed via the pressured-water or pressurized-air conduit from the inside against the filter surface and thus removing the deposits
Implementation Method 3
If the pump suction pressure is applied to the outlet tube, water from the surroundings is fed through the filter surface into the interior of the filter
