Slurry Mixer Cooling Jacket for High-Speed Mixing Heat Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Slurry manufacturing mixers experience heat generation due to friction, leading to gelation or coagulation of the slurry, which can be mitigated by shortening mixing time or reducing RPM, but this results in an insufficient mixing process.
Innovation Solution
A device with a rotation container having a mixing part and a slurry discharge part, featuring a cooling water passage between inner and outer containers, with a sealing member and valves to control cooling water flow, ensuring efficient cooling of the rotation container and slurry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mixer rotates at high speed to mix slurry efficiently, then mixing productivity is improved, but heat generation increases causing gelation or coagulation of the slurry
Solution Approach 1:
The patent implements a nested container structure where an inner container holding the slurry is placed inside an outer container. The cooling water passage is formed in the annular space between the inner and outer containers, allowing cooling water to flow around the inner container and directly cool the slurry during high-speed mixing without interfering with the mixing process.
Solution Approach 2:
Cooling water is introduced as an intermediary substance to transfer heat away from the slurry. The cooling water flows through the passage between the inner and outer containers, absorbing heat generated during mixing and preventing gelation or coagulation of the slurry while allowing high-speed rotation to continue.
2Temperature
If the mixing time is shortened to prevent heat generation, then temperature control is improved, but mixing process becomes insufficient
Solution Approach 1:
The cooling water flows continuously through the passage between the inner and outer containers during the entire mixing process. This continuous cooling action allows the mixer to maintain high-speed rotation for extended periods without temperature rise, ensuring complete mixing while preventing gelation or coagulation throughout the entire mixing duration.
3Temperature
If a cooling system is added to the mixer, then temperature control is improved, but device complexity increases
Solution Approach 1:
The cooling system is integrated into the existing mixer structure by forming the cooling water passage in the annular space between the inner and outer containers. This nested arrangement incorporates the cooling function within the existing container structure rather than adding separate external cooling equipment, thereby minimizing structural complexity.
Solution Approach 2:
The outer container serves multiple functions: it provides structural support for the mixer and simultaneously acts as a cooling jacket by containing the cooling water passage. This multi-functionality reduces the need for separate cooling components and simplifies the overall device structure.
