Spiral and Twisted Mixing Blade for Liquid Homogeneity
Solution Overview
Problem
Conventional mixing blades and apparatuses are inadequate for thoroughly mixing multiple liquids, leading to insufficient mixing and potential coating quality issues.
Innovation Solution
A mixing blade design featuring a first blade spirally formed around a first shaft and at least one second blade twisted around a second axis parallel to the first shaft, with the second blades positioned between facing blade portions of the first blade to enhance mixing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional stirring element with two spiral strips is used, then the structure is simple, but the mixing efficiency is insufficient
Solution Approach 1:
The mixing blade is divided into multiple functional components: a first spiral blade for initial fluid intake and a second twisted blade for enhanced mixing action. This segmentation allows each blade to perform specific mixing functions, improving overall mixing efficiency while maintaining reasonable structural complexity
Solution Approach 2:
The invention transitions from a single-planar spiral blade to a three-dimensional configuration by adding a second twisted blade that extends in a direction substantially perpendicular to the first blade. This dimensional addition creates multi-directional fluid disruption, significantly enhancing mixing efficiency
2Manufacturing precision
If a single spiral blade is used, then the device is simple, but the mixing of multiple liquids is insufficient
Solution Approach 1:
The mixing function is segmented between two blades with different geometries and orientations. The first spiral blade handles bulk fluid movement while the second twisted blade provides intensive mixing action, achieving uniform mixing of multiple liquids through divided functional responsibilities
Solution Approach 2:
The two blades are configured to rotate together but create different flow patterns due to their distinct geometries. The first blade generates spiral flow while the second blade creates turbulent mixing, and their combined dynamic action ensures thorough mixing of multiple liquids
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
The proposed mixing blade and apparatus effectively mix multiple liquids, ensuring sufficient coating quality by utilizing the spiral and twisted blade configurations to efficiently shear and mix fluids.
Implementation Method 1
The first spiral strip 21 spirally swirls the fluid in one direction around the axis over the substantially entire length of a housing 1
Implementation Method 2
the second spiral strip 22 is provided so that it is wound around the outer circumferential side of the spiral strip, and spirally swirls the fluid in the other direction around the axis
Implementation Method 3
the second blade is provided between facing blade portions in the first blade, the facing blade portions facing each other in a direction of the first shaft
