Variable Angle Side Entry Mixer for Preventing Sediment Build-Up

Engineering-focused side entry mixing system designed to control bottom sediment formation, stabilize long-term storage conditions, and improve circulation efficiency in large industrial tanks.

Why Sediment Forms in Large Storage Tanks

In long-term oil and chemical storage systems, sedimentation is not a single-factor problem. It is caused by a combination of velocity decay, density separation, and insufficient bottom shear stress.

  • Low flow velocity zones near tank bottom corners

  • Density difference between oil phases and impurities

  • Insufficient circulation energy in large-diameter tanks

  • Long residence time of heavy particles

Without proper flow redesign, sediment layers gradually harden and increase cleaning cost, downtime, and operational risk.

Flow Redirection Engineering Principle

The KEHENG variable angle side entry mixer is designed to change the trajectory of tangential flow inside the tank.      By adjusting the injection angle, the system eliminates stagnant zones and forces continuous bottom sweeping circulation.

  • Flow re-direction toward tank bottom boundary layer

  • Improved shear stress distribution across storage volume

  • Reduction of dead zones in large-diameter tanks

  • Stable long-cycle mixing behavior under low RPM conditions

What Makes Variable Angle Design Different

Adjustable Flow Geometry

Unlike fixed side-entry systems, the injection angle can be tuned according to tank behavior.

Targeted Bottom Scouring

Flow is directed to specific sediment-prone zones instead of uniform circulation only.

Process Adaptability

Suitable for changing media conditions such as viscosity increase or temperature variation.

Engineering Selection Considerations

Selecting a side entry mixer is not only about power rating. It depends on tank hydrodynamics,    sediment type, and circulation objectives.

  • Tank diameter and aspect ratio influence flow reach

  • Crude oil or chemical composition affects deposition tendency

  • Required turnover rate determines impeller design

  • Operating cycle impacts gearbox and seal selection

Operational Risk Reduction

Poor mixing design in storage tanks can lead to long-term operational risks that are often underestimated.

  • Increased sludge removal cost and downtime

  • Corrosion acceleration at tank bottom layers

  • Product quality inconsistency during discharge

  • Higher energy consumption due to inefficient circulation

Lifecycle Maintenance Strategy

KEHENG side entry mixers are designed for long-term industrial operation with minimal maintenance intervention.

  • Modular gearbox and seal replacement design

  • Easy-access maintenance structure for tank-side service

  • Predictable wear components for planned shutdowns

  • Extended service life under continuous operation conditions
