Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for dispersing substances in mixtures, such as slurry or liquid, face challenges in achieving uniform dispersion due to uneven processing times and incomplete dispersion, particularly in batch-type and continuous dispersion devices, where raw materials may accumulate or not receive sufficient shearing forces.
Innovation Solution
A circulating-type dispersing system that includes a device for continuous dispersion, two tanks connected in series via piping, and an adjusting valve to control the flow, ensuring that the processed mixture is circulated and uniformly dispersed by alternating the accumulation and supply between the tanks, allowing for efficient processing of large amounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a batch-type dispersion device is used, then the raw material can be processed in a vessel, but the raw material accumulates at particular locations and cannot evenly pass through the shearing force region, resulting in longer processing time
Solution Approach 1:
The patent implements continuous circulation of the mixture through the dispersing device, ensuring that the mixture continuously passes through the shearing force generation region without accumulation or stagnation, thereby achieving uniform dispersion and reducing processing time
2Loss of time
If a device for continuously dispersing is used, then processing time is reduced, but the raw material passes through the shearing force region only once, resulting in insufficient dispersion
Solution Approach 1:
The circulation system enables the mixture to pass through the shearing force generation region multiple times in succession, ensuring thorough and uniform dispersion while maintaining continuous operation and short processing time
Solution Approach 2:
The system uses level sensors to detect the mixture level in the tank and automatically controls the adjusting valve to open or close, creating a feedback mechanism that maintains continuous circulation and ensures uniform processing of all mixture portions
3Productivity
If a storage tank is provided along the piping to increase the amount of mixture to be processed, then processing capacity is increased, but some mixture passes through in short time while other portions stay for long time, resulting in non-uniform processing
Solution Approach 1:
The adjusting valve controls the outflow from the storage tank to maintain continuous circulation, ensuring that all mixture portions are processed by the dispersing device to the same degree while handling large amounts of material
Solution Approach 2:
Level sensors detect the mixture level in the storage tank and automatically control the adjusting valve to open when the level reaches the lower limit and close when it reaches the upper limit, ensuring uniform processing time for all mixture portions while maintaining high processing capacity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system enables repeated and uniform dispersion of large amounts of raw material, significantly reducing the time required to achieve a homogeneously processed mixture by controlling the flow between the tanks and utilizing sensors to manage the levels and agitators for uniform mixing.
Implementation Method 1
a device for continuously dispersing an insufficiently dispersed material may be obtained, since the raw material just one time passes through the region for generating shearing forces for dispersing
