Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purification systems face challenges in thoroughly removing fine particles like green algae, which can clog pumps and disrupt operations, and lack effective means to handle water pollutants such as silicates during the removal process, leading to inefficient water treatment and potential apparatus damage.
Innovation Solution
A fine particle separating apparatus featuring a filter with a rotary mesh and blade assembly, incorporating flow paths that allow effluents to flow in and out, preventing mesh clogging and enabling continuous operation. The apparatus includes a first filter with a mesh and a blade assembly, where at least a portion is rotatably mounted, with specific flow paths for effluent management and a pump to create flow, ensuring the mesh remains unclogged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mesh filter is used to separate fine particles, then separation effectiveness is improved, but the mesh becomes clogged by fine particles, interrupting operation
Solution Approach 1:
The mesh filter is designed to rotate about a rotation axis, transforming from a static to a dynamic structure. This rotation allows the mesh to periodically change its orientation relative to the water flow, preventing fine particles from accumulating and clogging the mesh surface, thereby maintaining continuous operation while preserving separation effectiveness
Solution Approach 2:
The system implements periodic backwashing where water flows in reverse direction at intervals to clean the mesh surface. This periodic cleaning action removes accumulated fine particles from the mesh, preventing clogging and ensuring reliable continuous operation while maintaining separation performance
2Productivity
If a pump is used to circulate water for treatment, then water treatment efficiency is improved, but water pollutants stick to the pump propeller, causing malfunction
Solution Approach 1:
A propeller guard is introduced as an intermediary structure between the water flow and the pump propeller. This guard prevents water pollutants and fine particles from directly contacting and sticking to the propeller blades, eliminating the risk of pump malfunction while allowing the pump to continue circulating water for efficient treatment
3Measurement precision
If the mesh is made finer to improve particle separation, then separation precision is improved, but the mesh is more prone to clogging
Solution Approach 1:
The mesh filter rotates to dynamically clear fine particles from its surface, enabling the use of finer mesh without increased clogging risk. The rotation mechanism continuously prevents particle accumulation, allowing high separation precision while maintaining simple maintenance requirements
Solution Approach 2:
Periodic backwashing is implemented to regularly clean the fine mesh surface, preventing clogging even when using very fine mesh for high-precision separation. This periodic maintenance approach keeps the system simple while enabling use of fine mesh for improved particle separation

AI summary
A fine particle separating apparatus includes a first filter having a first mesh, the first filter having a first section and a second section with the first mesh therebetween and rotatably mounted in the first filter part. A first flow path allows sludge to flow into the first filter, a second flow path allows an effluent from the first filter party to flow therein, and a third flow path is provided to discharge the effluent from the second flow path to the outside. At least a portion of the effluent flowing into the second flow path is provided to the first filter part in a fluid loop along a fourth flow path, and a fifth flow path is defined in the first section to allow the effluent from the fourth flow path to pass through the first filter part. A storage tank and a pump are also provided.
