Fluid-Driven Strainer Cleaning for Clogged Filter Mesh
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing strainers require manual visual inspection and cumbersome disassembly for cleaning, making it difficult to check and remove accumulated foreign substances from the filter mesh.
Innovation Solution
A strainer with a non-powered cleaning function that uses a pressure gauge, glass, and a 3-way discharge valve to facilitate easy detection and removal of foreign substances, employing a brush scraper and propeller mechanism to clean the filter mesh without power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual visual inspection and disassembly are used to check and clean the filter mesh, then the strainer can be maintained, but the operation becomes cumbersome and inconvenient
Solution Approach 1:
The strainer enables self-cleaning through an automatic cleaning mechanism where a cleaning brush rotates to remove foreign substances from the filter mesh surface, and a collection scraper gathers the removed substances into a collection chamber, eliminating the need for manual disassembly and visual inspection
Solution Approach 2:
The invention extracts the cleaning function from manual operation by incorporating a dedicated cleaning mechanism with a rotating brush and scraper that automatically remove and collect foreign substances from the filter mesh, separating the cleaning action from the main filtration function
2Reliability
If the cover is tightly coupled to the main body to ensure sealing, then filtration effectiveness is improved, but separation of the cover from the main body becomes difficult
Solution Approach 1:
The system performs self-maintenance through automatic cleaning mechanisms that operate without requiring cover removal, with the cleaning brush and scraper working internally to remove foreign substances while the cover remains tightly coupled to maintain sealing and filtration 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
Enables easy and efficient cleaning of the filter mesh by rotating brushes to remove foreign substances, using fluid flow to power the mechanism, thereby simplifying maintenance and preventing substance accumulation.
Implementation Method 1
using fluid flow to power the mechanism

AI summary
Disclosed is a strainer having a non-powered cleaning function. The present invention enables filtration of foreign substances from fluid by disposing a cylindrical filter mesh inside a main body of the trainer, such that the fluid from an inlet pipe flows through the filter mesh toward an outlet pipe. The present invention also enables cleaning of the filter mesh by disposing a central shaft of a scraper at the center of the filter mesh, and rotating the central shaft such that brushes connected thereto scrape off foreign substances collected on the filter mesh.
