Flat-Jet Injection Mixing Chamber for Homogeneous Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing devices for combining a base with a catalyst often result in non-homogeneous mixtures due to preferential flow paths and require complex structures that complicate maintenance, particularly cleaning.
Innovation Solution
A mixing device with a first inlet for a first product and a second inlet for a second product, where the second product is injected as a flat jet into the mixing chamber, creating a swirl effect and ensuring better distribution and contact surface between the products, enhancing homogeneity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If mixing elements such as propeller or static mixer are provided, then mixing effectiveness is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The patent removes traditional mixing elements (propellers, static mixers) from the system and replaces them with a nozzle-based injection system. The second product is injected as a flat jet directly into the first product stream, creating turbulence and mixing through the injection process itself rather than through separate mixing components.
Solution Approach 2:
The patent uses fluid dynamics principles by injecting the second product as a flat jet into the first product stream. The hydraulic injection process creates turbulence and promotes mixing through the interaction of the two product streams, eliminating the need for mechanical mixing elements.
2Manufacturing precision
If mixing elements such as propeller or static mixer are provided, then mixing effectiveness is improved, but cleaning difficulty increases
Solution Approach 1:
The patent removes traditional mixing elements (propellers, static mixers) that create hard-to-reach areas and eliminates the cleaning problems associated with these components. The simplified chamber design allows for easier access and cleaning of all surfaces.
Solution Approach 2:
The injection system creates self-mixing through the turbulence generated by the flat jet injection, eliminating the need for mechanical mixing elements that would require maintenance and cleaning. The system uses the flow dynamics itself to achieve mixing without additional components.
3Device complexity
If traditional injection methods are used, then device simplicity is maintained, but mixing homogeneity deteriorates due to preferential flow paths
Solution Approach 1:
The patent applies a specialized nozzle design at the injection point to create a flat jet pattern. This localized modification to the injection method creates specific flow patterns and turbulence in the mixing zone, improving homogeneity without complicating the overall device structure.
Solution Approach 2:
The patent changes the injection parameters by injecting the second product as a flat jet rather than through traditional methods. This parameter change in the injection process creates the necessary turbulence and contact between product streams for homogeneous mixing while maintaining device simplicity.

Function Achieved in This Case
The solution achieves homogeneous mixing of the products by facilitating turbulence and ensuring thorough integration, simplifying maintenance and improving the mixing process.
Implementation Method 1
Injecting the second product into the mixing chamber in the form of a flat jet, into which the first product is introduced, allows for a better distribution of the second product in the first product and a better contact surface between the two products
