Lift Type Pore-Controllable Fiber Filter for Uniform Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In pore-controllable fiber filters, non-uniform distribution of force along the fiber filter material leads to deteriorated filtration performance, especially when the material is long, resulting in loosely formed filtration layers.
Innovation Solution
A lift type pore-controllable fiber filter design that includes a filter tank with a strainer, a lifting driver with a piston, and upper and lower filter material fixing plates to uniformly distribute force across the fiber filter material, ensuring consistent tension and pore formation.

1Area of stationary object
If the fiber filter material is made long to increase filtration area, then the filtration capacity is improved, but the twist tension is not uniformly transmitted causing loose filtration layers and deteriorated filtration performance
Solution Approach 1:
The fiber filter material is divided into multiple segments along its length, with each segment being twisted independently around the porous tube. This segmentation allows twist tension to be effectively applied to each section separately, preventing the tension loss that occurs in long continuous materials and ensuring uniform filtration layer density throughout the entire filter.
Solution Approach 2:
A twisting mechanism acts as an intermediary device between the fiber filter material and the porous tube, applying controlled twist tension to each segment. This intermediary mechanism ensures that the twisting force is uniformly distributed along the length of the material, resolving the tension transmission problem in long filters.
2Manufacturing precision
If the fiber filter material is made short to ensure uniform twist tension transmission, then the filtration layer density is improved, but the filtration area is reduced
Solution Approach 1:
Instead of using one long continuous piece of fiber material, the filter employs multiple shorter segments arranged along the porous tube. Each segment is twisted independently, ensuring uniform tension transmission while the collective arrangement of multiple segments provides sufficient total filtration area.
