A Rotary Jet Mixer works by using powerful, rotating liquid jets positioned beneath the surface to create thorough and dynamic mixing within a tank.
Based on the provided information, the operation of a rotary jet mixer relies on a specific set of actions designed to achieve efficient circulation and homogenization within a liquid volume. Unlike fixed-position mixers, these systems employ movement and directed force to process the tank's contents effectively.
Operating Principle of Rotary Jet Mixers
The core operating principle of a Rotary Jet Mixer involves directing high-velocity liquid streams through moving nozzles within the tank. This creates turbulence and flow patterns that ensure comprehensive mixing.
Here's a breakdown of the key elements involved in their operation, drawing directly from the reference:
- Submerged Position: The Rotary Jet Mixers are positioned under the liquid surface. This placement is crucial as it allows the jets to directly influence the bulk of the liquid volume from below, preventing splashing and maximizing energy transfer for mixing.
- Liquid Feed: Liquid is fed through the nozzles of the Rotary Jet Mixer. This liquid, often drawn from the tank itself via a pump, is the medium used to generate the powerful jets required for mixing.
- Closed Circulation Loop: To achieve optimal circulation within the tank, the system uses a closed circulation loop. This means liquid from the tank is continuously withdrawn, pumped through the jet mixer nozzles, and then returned to the tank, creating a constant flow that drives the mixing process.
- Nozzle Rotation: The system features Two or four nozzles rotate around both the horizontal and vertical axes. This unique multi-axis rotation ensures that the high-velocity jets sweep across the entire interior surface of the tank, covering all areas and preventing dead zones where mixing might not occur.
| Component/Action | Role in Mixing |
|---|---|
| Submerged Placement | Direct energy into liquid bulk, prevent splashing |
| Liquid Feed via Nozzles | Creates high-velocity streams for turbulence |
| Closed Circulation Loop | Provides continuous flow and power to the jets |
| Multi-Axis Nozzle Rotation | Ensures jets cover entire tank volume, eliminating dead spots |
This combination of submerged, high-velocity, and omni-directional jet action allows rotary jet mixers to effectively blend liquids, suspend solids, and maintain uniformity in tanks.
