Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The media-agitation type wet disperser faces issues with reduced shearing force and wear of the separator due to group motion of media, leading to lower treatment efficiency and increased wear of parts, especially when using smaller media diameters.
Innovation Solution
The design incorporates a rotor composed of multiple small rotors with cylindrical agitation parts and disk-shaped holding parts, featuring throughholes and a specific L/D ratio, curved chamber ends, and a projection at the outer periphery to create circulation flow, preventing group motion and enhancing shearing force, while maintaining the media's flow speed to reduce wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If smaller diameter media is used to reduce fine particle diameter, then dispersion fineness is improved, but group motion of media occurs leading to reduced shearing force and lower treatment efficiency
Solution Approach 1:
The rotor is divided into multiple rotor blades arranged radially, creating multiple localized agitation zones. This segmentation prevents uniform group motion of media while maintaining strong shearing forces in each zone, thereby preserving treatment efficiency even with small diameter media
Solution Approach 2:
The rotor blades are designed to rotate at high speed, creating dynamic circulation flow that continuously changes the position and velocity of media particles. This dynamic motion prevents media from settling into uniform group patterns, maintaining consistent shearing action and treatment efficiency
2Manufacturing precision
If smaller diameter media is used to reduce fine particle diameter, then dispersion fineness is improved, but separator wear increases due to high flow speed of media
Solution Approach 1:
The separator is designed with multiple radial blades that segment the media flow into separate channels. This segmentation distributes the high-velocity media flow across multiple paths, reducing the concentrated impact and wear on any single area of the separator
Solution Approach 2:
The rotor blades act as an intermediary element between the driving force and the media particles. They transfer energy to the media in a controlled manner, creating circulation flow that reduces direct high-velocity contact between media and separator surfaces, thereby reducing wear
3Productivity
If media group motion is suppressed to increase shearing force, then treatment efficiency is improved, but energy consumption increases
Solution Approach 1:
The system uses dynamic rotation of multiple rotor blades to create continuous circulation flow. This dynamic approach generates strong shearing forces through rotational motion rather than static compression, achieving high treatment efficiency while maintaining reasonable energy consumption through efficient momentum transfer
