Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fluid mixing apparatuses are inadequate in increasing the volume of fluid moved beyond the pump's volumetric flow rate and reducing the time required to turnover a mixing vessel.
Innovation Solution
The apparatus features a mixing housing with a converging-to-straight or converging-to-diverging inlet nozzle and radial inlets, creating a spiraling turbulent flow that enhances fluid movement, allowing for a volumetric flow rate increase of at least three times and efficient mixing within a vessel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional mixing apparatuses are used, then the structure is simple, but the volumetric flow rate is limited to roughly one times the pump flow rate
Solution Approach 1:
The mixing apparatus divides the flow path into multiple segments through primary and secondary inlets positioned at different locations. The primary inlet receives fluid from the pump while the secondary inlet receives fluid from the vessel, creating separate flow paths that merge within the mixing chamber to achieve enhanced volumetric flow rate.
Solution Approach 2:
The invention introduces radial inlet nozzles that receive fluid from the vessel wall and direct it axially into the mixing chamber, adding a radial dimension to the flow patterns. This multi-dimensional flow arrangement increases the effective mixing volume and volumetric flow rate beyond what conventional single-dimension mixing achieves.
2Loss of time
If conventional mixing apparatuses are used, then the device is simple, but the time to turnover the vessel is excessive
Solution Approach 1:
The mixing apparatus creates dynamic flow patterns through the interaction of primary and secondary flows at different velocities and directions. The axial flow from the primary inlet combines with the radial flow from secondary inlets to generate turbulent mixing patterns that rapidly turnover the vessel contents.
Solution Approach 2:
The invention utilizes hydraulic principles by designing the inlet nozzles and flow paths to optimize fluid dynamics. The converging nozzle geometry and radial inlet arrangement create pressure differentials and flow velocities that enhance mixing efficiency and reduce turnover time.
3Productivity
If high volumetric flow rate is achieved, then mixing efficiency improves, but the device complexity increases
Solution Approach 1:
The mixing apparatus applies local quality by positioning primary and secondary inlets at specific locations within the vessel. The primary inlet is positioned to receive high-velocity flow from the pump while secondary inlets are positioned at the vessel wall to receive slower flow, creating localized flow zones that enhance overall mixing efficiency.
Solution Approach 2:
The invention changes flow parameters by using a converging nozzle geometry that increases fluid velocity and pressure. The radial inlet nozzles are angled to create specific flow directions, and the mixing chamber geometry is optimized to maintain turbulent flow patterns that enhance mixing while managing device complexity.

AI summary
An apparatus for mixing fluids can provide at least three times a volumetric flow of a volumetric flow rate of a pump to have a specific volumetric flow rate. The apparatus can include a mixing housing, an inner cavity, and an inlet nozzle adjacent a first end of the mixing housing and at least partially extending into the inner cavity. The apparatus can also include a radial inlet formed through a portion of the mixing housing and an outlet adjacent a second end of the mixing housing. The apparatus can form a portion of a system for mixing fluids, separating fluids, or both.
