Angled Strut Filter Support for Belt Filtration Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid filtration systems are costly and complex, with conventional filter belt supports limiting filtering efficiency and causing stress on the filter belt due to uniformly aligned struts that block portions of the belt surface and concentrate weight, leading to reduced lifespan.
Innovation Solution
A filter support system with angled, non-longitudinal struts and modular designs that increase the exposed filter belt area and distribute the weight of accumulated solids more evenly, preventing consistent blockage and stress on the belt.

Engineering Contradiction Analysis
1Productivity
If conventional uniformly aligned struts are used to support the filter belt, then the structure is simple and easy to manufacture, but the filtering efficiency is limited and stress concentrates on the belt causing reduced lifespan
Solution Approach 1:
The patent applies asymmetry by configuring struts at different angles rather than uniformly aligned. Specifically, first struts are positioned at a first angle and second struts are positioned at a second angle, creating an asymmetric pattern that prevents consistent blockage of the filter belt surface and distributes stress more evenly, thereby improving filtering efficiency while maintaining structural feasibility
Solution Approach 2:
The patent introduces angular variation as an additional dimension to the strut configuration. Instead of only varying strut positions along the belt length, the invention varies the angular orientation of struts relative to the belt surface, creating a two-dimensional configuration space that increases exposed filter area and reduces stress concentration points
2Duration of action of stationary object
If uniformly aligned struts are used, then manufacturing is simpler, but stress concentrates on specific areas of the belt reducing its lifespan
Solution Approach 1:
The asymmetric strut arrangement with different angles distributes the weight of accumulated solids more evenly across the filter belt, preventing stress concentration at specific locations. This extends the filter belt lifespan by reducing localized wear and deformation, while the modular nature of the asymmetric pattern keeps manufacturing complexity manageable
Solution Approach 2:
The patent applies local quality by having different struts oriented at different angles in different regions of the support structure. This localized variation in strut orientation optimizes stress distribution at each specific location along the belt, preventing uniform stress patterns that would lead to predictable failure points
3Area of stationary object
If conventional filter supports are used, then the device complexity is low, but the exposed filter belt area is reduced due to consistent blockage by aligned struts
Solution Approach 1:
The asymmetric configuration of struts at different angles prevents consistent blockage patterns that occur with uniformly aligned struts. By varying the angular orientation, the invention ensures that gaps between struts are distributed more evenly across the filter belt surface, maximizing the exposed filter area available for effective filtration
Solution Approach 2:
The support structure is segmented into multiple struts with different angular orientations rather than using a single uniform pattern. This segmentation allows each strut to serve a specific function in terms of stress distribution and surface exposure, collectively maximizing the overall exposed filter belt area

AI summary
The present technology is directed generally to fluid treatment systems. In particular, several embodiments are directed toward filter supports configured to be positioned adjacent a filter belt within a filter belt filtration system. In one embodiment, the filter support can have a longitudinal axis generally parallel to the direction of movement of the filter belt. The filter support can include a plurality of struts spaced apart by a plurality of openings, and at least one of the plurality of struts extends across a portion of the filter support such that a longitudinal axis of the at least one strut is positioned at an angle with respect to the longitudinal axis of the filter support.
