Blade Stirring Centrifugal Extractor

Key Features

Key Feature	EN
Key Feature 1	Upper Suspension Design: Eliminates bottom mechanical seals, preventing leakage and reducing maintenance.
Key Feature 2	Low Shear Mixing: Optimized blade geometry prevents emulsification in sensitive feeds.
Key Feature 3	Low Energy: Reduced motor power requirements compared to annular gap models.
Key Feature 4	Corrosion Resistant: Available in polymer composites for acid/alkali resistance.
Key Feature 5	Easy Access: Top-loading rotor allows for rapid maintenance.

Process Characteristics (Technical Analysis):

Macroscopic Mixing Regime: Unlike the intense turbulence of annular contactors, the CTL uses a central blade to generate macroscopic circulation. This characteristic is critical for "Easy Separation" systems (large density difference $\Delta\rho > 0.1$) or feeds containing surfactants. It ensures phase equilibrium without generating secondary hazes (fine emulsions) that are difficult to separate, making it the ideal replacement for gravity settler tanks.

Typical Industries & Applications

1. Environmental Engineering: Oil-water separation (degreasing fluids), phenol removal from wastewater.

2. Basic Chemical Manufacturing: Washing of non-viscous organic solvents (Acid/Alkali wash).

3. Food Industry: Edible oil refining where gentle handling prevents oxidation.

Working Principle

Step 1 (Mixing): Light and heavy phases enter the bottom mixing chamber. The rotating blade creates intense Taylor vortices for instant mass transfer.
Step 2 (Separation): The mixture is drawn into the high-speed drum. Centrifugal force (300-500G) rapidly stratifies the liquids.
Step 3 (Discharge): Liquids overflow via weirs into stationary collection volutes.

Item	Standard configuration	Optional configuration
Wetted parts material	Stainless-steel wetted parts (drum and blade wheel) suitable for standard chemical service.	High-alloy stainless steel (e.g. 316L, 904L) or titanium; abrasion-resistant coatings for solids-laden or highly corrosive systems.
Mechanical layout	Top-hung rotor with upper bearing housing and simple support frame for easy access and maintenance.	Enclosed frame with sound-attenuation panels, vibration-isolating base, integrated working platform and guardrails.
Drive & control	Direct-coupled motor, fixed-speed operation with local on/off control.	Variable-frequency drive (VFD) for soft start and speed regulation; soft-starter; PLC control with interlocks to upstream / downstream equipment.
Automation & safety	Basic local instruments (ammeter, local start/stop) and mechanical overspeed protection.	Bearing-temperature monitoring, continuous vibration monitoring, motor overload and earth-fault protection, nitrogen purging for solvent or explosion-risk service.
Cleaning & washing	Drain ports and access covers for manual cleaning of the drum and housing.	CIP / spray-washing system for internal automatic cleaning, removable blade assemblies, quick-opening covers for fast inspection and turnaround between campaigns.
