A pressure consumption regenerating filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current washing machine filters are ineffective in capturing microplastics, particularly microfibers, due to their large aperture sizes, which leads to clogging and increased pressure consumption, requiring manual regeneration or frequent replacement, and existing solutions fail to efficiently regenerate pressure consumption, resulting in reduced filter effectiveness and potential pump damage.
Innovation Solution
A separator system with a sieve structure and a filter pressure regeneration apparatus, featuring a conduit and nozzle assembly that directs cleaning fluid to dislodge filtered material from the sieve, allowing it to be swept away and collected, thereby maintaining filter efficiency and reducing pressure consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a sieve structure with small aperture size is used to capture microfibers, then filtration effectiveness is improved, but pressure consumption increases and the filter clogs quickly
Solution Approach 1:
The filter system performs self-cleaning through a regeneration mechanism where a jet of fluid is directed at the sieve structure to dislodge captured microfibers. This self-service capability allows the filter to maintain small aperture sizes for effective microfiber capture while automatically removing accumulated debris that would otherwise cause clogging and pressure increase, enabling continuous operation without manual intervention
Solution Approach 2:
The system discards accumulated microfibers from the sieve structure by directing a fluid jet through a conduit to blow the captured material off the filter surface. This discarding mechanism prevents clogging and maintains pressure consumption at acceptable levels, allowing the filter to operate continuously with small aperture sizes for effective filtration
2Stress or pressure
If manual cleaning of the filter is performed, then pressure consumption is regenerated, but operation time is lost and manual intervention is required
Solution Approach 1:
The filter system performs self-cleaning through a regeneration mechanism where a jet of fluid is directed at the sieve structure to dislodge captured microfibers. This self-service capability allows the filter to maintain small aperture sizes for effective microfiber capture while automatically removing accumulated debris that would otherwise cause clogging and pressure increase, enabling continuous operation without manual intervention
Solution Approach 2:
The regeneration process operates periodically, automatically directing a fluid jet through a conduit at the sieve structure to dislodge and remove accumulated microfibers. This periodic self-cleaning action maintains pressure consumption at acceptable levels without requiring manual intervention or stopping operation, thereby eliminating time loss associated with manual filter maintenance
3Productivity
If the filter is not regenerated, then continuous operation is maintained, but pump damage may occur due to excessive pressure
Solution Approach 1:
The filter system performs self-cleaning through a regeneration mechanism where a jet of fluid is directed at the sieve structure to dislodge captured microfibers. This self-service capability allows the filter to maintain small aperture sizes for effective microfiber capture while automatically removing accumulated debris that would otherwise cause clogging and pressure increase, enabling continuous operation without manual intervention
Solution Approach 2:
The system performs preliminary cleaning action by directing a fluid jet through a conduit at the sieve structure to dislodge and remove accumulated microfibers before pressure consumption reaches levels that could damage the pump. This preliminary maintenance action ensures continuous operation can proceed without interruption while protecting the pump from excessive pressure

AI summary
A separator preventing microplastics from entering the environment through regenerating the pressure consumption of filters for removing microplastics an effluent. The separator for separating microplastics from an effluent includes a chamber with an inlet and an outlet, a sieve structure forming a permeable barrier between the inlet and the outlet to filter the effluent, the sieve structure thus having an inlet side for unfiltered effluent and an outlet side for filtered effluent. The further includes a filter pressure regeneration apparatus for dislodging filtered material from the sieve structure. The filter pressure regeneration apparatus includes a conduit and a nozzle assembly having at least one cleaning nozzle directed towards the outlet side of the sieve structure to dislodge filtered material from the inlet side of the sieve structure.
