Detailed Analysis of Mixing Tank (with Agitator)

Mixing Tank Overview

Mixing tanks are essential equipment in modern industrial production, widely used in the chemical, pharmaceutical, food, coating, and dye industries for mixing, stirring, and reaction processes. The design and performance of a mixing tank directly impact product quality and production efficiency.

Mixing Tank Structure

1. Tank Body

• Material: Typically constructed of durable materials such as stainless steel and carbon steel.

• Shape: Available in a variety of shapes, including cylindrical, conical, and elliptical, to meet diverse process requirements.

• Capacity: Ranges from a few liters to tens of cubic meters.

• Internal Surface Treatment: Typically polished to ensure material cleanliness and prevent adhesion.

2. Agitator (Core Component)

• Function: Thoroughly mixes and stirs the materials in the tank.

• Common Types:

           Paddle Agitator: Simple structure, highly versatile, suitable for low-viscosity materials.

           Turbine Agitator: Fast stirring speed, strong shear force, suitable for high-viscosity materials.

           Anchor Agitator: Large stirring area, suitable for high-viscosity materials that tend to stick to the wall.

           Spiral Ribbon Agitator: Wide stirring range, suitable for high-viscosity materials.

3. Transmission

• Components: Motor, reducer, coupling, etc.

• Function: Provides stable and appropriate power for the agitator.

          Motor: Power source, with different power options depending on the size of the mixing tank and process requirements.

          Reducer: Reduces motor speed, increasing agitator torque.

          Coupling: Connects the motor and reducer to transmit power.

Mixing Tank Features

1. Diverse Structures and Configurations

• Materials such as carbon steel and stainless steel can be used according to production process requirements.

• Heating and cooling devices can be installed to meet different process requirements.

• Heating methods include jacketed electric heating and coil heating.

2. Highly Efficient Mixing Performance

• The rotating agitator shears, stirs, and mixes various materials.

• The agitator speed, shape, and material properties influence the mixing effect.

• Accessories such as baffles and guide tubes can further improve mixing efficiency.

3. Flexible Control System

• Manual and automatic control of feed, discharge, and mixing is possible.

• This makes the mixing tank operation more flexible and convenient.

4. Reliable Sealing Performance

• Mechanical seals are commonly used shaft seals, offering reliable sealing and long service life.

• They can meet sealing requirements in various complex working conditions.

5. User-Friendly Design and Operation

• The design structure can be standardized and user-friendly.

• Cleansing and maintenance are relatively easy, reducing production costs.
