Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lateral flow inclined-plate and horizontal-pipe sedimentation processes in water treatment face issues such as bending and creep of inclined plates, difficulty in sediment discharge, low settling efficiency, and high manufacturing costs, as well as challenges in installation and effective utilization of cross-sectional area.
Innovation Solution
A sedimentation plate design featuring perpendicular first and second rib plates forming water and mud channels, with a height ratio of 1.5-5, made of polyolefin, and a sedimentation assembly with a box-type frame and flushing mechanism to enhance rigidity, facilitate sedimentation, and improve settling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inclined plates are used at an angle of 60° to achieve high settling efficiency, then the settling efficiency is improved, but the inclined plate bends and creeps after long-term use
Solution Approach 1:
The plate is divided into multiple rib structures (first rib plates and second rib plates) arranged perpendicular to each other, creating a grid-like reinforcement system that segments the plate structure to prevent bending and creeping while maintaining settling efficiency
Solution Approach 2:
The patent introduces a three-dimensional rib structure by adding rib plates extending in directions perpendicular to the plate surface, transforming the traditional two-dimensional plate into a three-dimensional reinforced structure that resists bending and creeping forces
2Volume of moving object
If multi-stage bending arrangement of inclined plates is adopted to utilize height, then the effective utilization of height is improved, but sediment disperses and falls into water during discharge, reducing settling efficiency
Solution Approach 1:
The plate is segmented with multiple rib structures that create distinct channels and support zones, allowing sediment to be guided along defined paths during discharge, preventing dispersion into water while maintaining multi-stage height utilization
3Adaptability or versatility
If traditional horizontal pipe with diamond corner structure is used, then the water channel and mud channel are independent, but the manufacturing process faces difficult withdrawal and poor quality
Solution Approach 1:
The patent transitions from a two-dimensional diamond corner structure to a three-dimensional perpendicular rib structure, where first and second rib plates extend in perpendicular directions from the plate surface, creating independent channels while enabling straightforward manufacturing through perpendicular positioning
4Adaptability or versatility
If traditional horizontal pipe structure is used to separate water and mud channels, then the channels are independent, but the effective utilization of cross-sectional area is only about 60%
Solution Approach 1:
The patent uses three-dimensional perpendicular rib structures extending from the plate surface to create independent water and mud channels, maximizing the utilization of available cross-sectional area by utilizing vertical space rather than only horizontal separation
