Dynamic Mixer Head With Segmented Vanes and Grooved Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dynamic mixers fail to effectively split and deflect back component substances into mixing chambers, limiting their mixing efficiency, especially for viscous compositions like dental impression compounds.
Innovation Solution
A dynamic mixer head design featuring a rotor with quarter-circle vanes and a housing with grooves and spacers, allowing component substances to be split and deflected back into mixing chambers, enhancing the mixing effect by using a connecting cover with outlet openings and a housing with grooves that accommodate the rotor and facilitate the separation and mixing of substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional dynamic mixers are used, then the structure is simple, but the mixing efficiency is insufficient because components cannot be split into smaller streams nor deflected back into mixing chambers
Solution Approach 1:
The rotor is segmented into multiple vanes (at least three vanes) arranged radially, creating multiple separate mixing chambers and allowing components to be split into smaller streams within each chamber, thereby improving mixing efficiency without excessive complexity
Solution Approach 2:
The housing includes a transition section with a conical surface that directs flow from the pre-chamber into the main chamber at an angle, adding a dimensional change to the flow path and enabling components to be deflected back into mixing chambers
2Productivity
If components flow directly through the mixer, then the structure is simple, but the components cannot be deflected back into mixing chambers for thorough mixing
Solution Approach 1:
The transition section with conical surface creates a three-dimensional flow path that directs components from the pre-chamber at an angle into the main chamber, enabling deflection back into mixing chambers
Solution Approach 2:
The rotor rotates continuously, maintaining continuous mixing action and ensuring components are constantly deflected back into mixing chambers for thorough and sustained mixing

AI summary
A dynamic mixer head has a connecting cover, a rotor and a housing. The connecting cover has a rotor opening. The rotor has a first rotor axle mounted in the rotor opening and a mixing rotor connected with the first rotor axle. The mixing rotor has multiple vaned inner rotors with quarter-circle shaped multiple vanes and a vaned front rotor opposite to a second rotor axle of the mixing rotor with multiple vanes complementary to the multiple vanes of the multiple vaned inner rotors. The housing mounted to the connecting cover has at least two grooves disposed on the circular partition. Each of the at least two grooves has a spacer along each of the at least two grooves. The dynamic mixer head can enhance the mixing effect of two different component substances during rotation.
