Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas supply devices for stirring arrangements are complex, costly, and inefficient, with separate components requiring rigid supports to prevent flow-induced oscillations, and often interfere with the primary tasks of stirring, such as mixing and heat transfer.
Innovation Solution
A rotating distribution bushing with co-rotating outlet lines that discharge gas directly near the stirring blades, allowing targeted gas release and simplifying the structure by integrating a central stationary supply line with a rotating distribution bushing and outlet lines, eliminating the need for external supports and reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gas supply devices with separate components and rigid supports are used, then gas can be supplied to the stirring body, but the device complexity increases and material costs rise due to the need for multiple components and supports to prevent flow-induced oscillations
Solution Approach 1:
The gas supply device merges the distribution bushing and outlet lines into a single integrated rotating assembly that rotates with the stirring body hub. This eliminates the need for separate stationary supply lines and multiple discrete components, reducing structural complexity while maintaining reliable gas supply to the stirring blades.
Solution Approach 2:
The gas supply system transitions from a static configuration with rigid supports to a dynamic rotating assembly. The distribution bushing and outlet lines rotate together with the stirring body, eliminating flow-induced oscillations without requiring additional support structures, thereby simplifying the overall device design.
2Reliability
If gas is supplied via stationarily installed supply lines below or on the sides of the stirring body, then gas can be distributed, but the gas is supplied at a relatively large distance from the stirring body reducing dispersal efficiency
Solution Approach 1:
The gas supply system rotates with the stirring body, bringing the outlet lines into immediate proximity of the stirring blades. This dynamic positioning enables gas to be supplied directly at the point of need, significantly improving dispersal efficiency compared to stationary supply lines positioned at a distance.
Solution Approach 2:
Gas is supplied locally at the immediate vicinity of each stirring blade through co-rotating outlet lines positioned within the volume swept by the stirring body. This localized gas supply optimizes the interaction between gas and fluid at the blade-gas interface, enhancing dispersal efficiency.
3Productivity
If outlet openings are arranged within the volume swept by the stirring body or in immediate outflow zones, then gas dispersal is optimized, but the risk of interfering with primary stirring tasks increases
Solution Approach 1:
Gas is supplied at localized positions within the volume swept by the stirring body through outlet openings arranged on the co-rotating outlet lines. This localized supply occurs at the immediate vicinity of the stirring blades where gas dispersal is most effective, while the co-rotating design ensures gas is introduced in sync with blade passage, preventing interference with stirring tasks.
Solution Approach 2:
The outlet lines and their openings rotate synchronously with the stirring body, dynamically positioning the gas discharge points within the optimal zones for dispersal. This dynamic coordination ensures gas is released at the correct locations and times, maximizing dispersal efficiency without disrupting the stirring action.
4Reliability
If multiple separate components with rigid supports are used for gas supply, then gas can be supplied reliably, but the manufacturing cost increases due to the need for expensive materials to prevent corrosion and flow-induced oscillations
Solution Approach 1:
The gas supply device combines the distribution bushing, outlet lines, and support structure into a single integrated rotating assembly. This merger eliminates the need for multiple separate components requiring individual corrosion protection and support structures, significantly reducing material costs and simplifying manufacturing while maintaining reliable gas supply.
