Description

I, Agitator definition

The agitator is also called a mixer or stirrer, it is a device that enables forced convection and uniform mixing of different media.
The agitators used in industrial production are called industrial agitators, which are the most widely used fluid mixing equipment. They are capable of mixing various forms of materials, such as liquids, suspensions, dispersions, pastes, and so on. Industrial agitator has wide applications in the food, beverage, pharmaceutical, chemical, paper, petroleum, and other industries.

II,Structure of agitator


The left picture is the sketch of a kettle reactor.
The Parts pointed except A combine the agitator this reactor. In another saying, the agitator are mainly made from parts B to G.  
The parts names are as following:
A, Motor
B, Frame 
C, D,  Shaft seal
E, Transmission shaft
F, Mixing shaft
G, Impeller or paddle
Transmission device of the agitator is made of B , C, D, E.
The transmission device would include a reducer if speed adjustment function is required.


III, Agitator selection steps and basis

There are 8 steps to determine the agitator types and specifications:
Steps Step Name Selection basis Note
1

Determine the agitator type.

Process conditions, mixing purposes, and requirements. The choice of agitator type should fully grasp the power characteristics of the agitator and agitator in the mixing process produced by the flow state and the cause-and-effect relationship between the various purposes of mixing.
2

Determine the motor power, stirring speed, stirrer diameter.

Stirrer type. Flow state produced by the agitator in the mixing process.
Process requirements for control of stirring and mixing time, settling speed, and dispersibility.
Methods: Experimental means, computer simulation design.
3

Determine the reducer model.

Motor power, mixing speed, process conditions. If the reducer is selected according to the actual working torque, the actual working torque should be less than the permissible torque of the reducer.
4

Determine the type of frame and coupling.

The output shaft head of the reducer dia. and the support mode of the mixing shaft system    /
5

Determine the type of shaft seal

Frame stirring shaft head dia., installation space and working pressure, working temperature   /
6

Determine the mixing shaft structure type.

Installation form and structural requirements   /
7

Determine the bottom cover, flange base, or flange flang.

The frame of the nominal dia., the mixing shaft of the shaft type, and the pressure level
  /
8

Determine whether to configure auxiliary support.

Support and vibration conditions
  /

Type Agitator Name Photo Description Application

Impeller or paddle's types:



Paddle stirrer agitator

Paddle stirrer agitator Paddle blades make liquid flow to produce strong cutting and traction effects. It is used for mixing the low to medium viscosity mixtures, such as water, emulsions, paints, cosmetics, and so on.

Propeller stirrer agitator

Propeller stirrer agitator It produces convective circulation at low speeds, and turbulent at high speeds.
It can stir up all the materials with large specific gravity (such as NI catalyst) settled at the bottom of the kettle, and suspend them in the liquid. 
It is applicable to high viscosity mixture, such as paint, resin, glue, etc.
Generally, it is suitable for solid and liquid catalytic suspension reactions.

Centrifugal Stirrer agitator

When the agitator is running, the paddles will be opened by centrifugal force.
Centrifugal stirrer adopts rotating centrifugal force to produce liquid flow.
It is suitable for the occasion of mixture with low viscosity and small particles, such as suspension, sludge etc.

Achor or frame stirrer agitator

Achor or frame stirrer agitator These agitators are commonly used for heat transfer, crystal precipitation operations, and agitation of high-viscosity liquids, highly concentrated slurries, and settling slurries.  For the mixing of porridge-like materials.

Folded-blade turbine stirrer agitator

Folded-blade turbine stirrer agitator It can make the material circulate in the reactor. The main effort is volumetric circulation. The shear is small. The up-and-down tumbling effect is good.
Folded-blade turbine stirrer is generally adapted to the reaction of gas-liquid phase mixing, and the stirrer rotation should generally be selected above 300r/min. 

According to the installation positions:

Bottom entry agitator

Bottom entry agitator It is an agitator is a direct mixing equipment. The agitator is directly installed in the bottom of the container. For the mixing mixed liquids or high viscosity medium.

Vertical agitator

Vertical agitator Vertical agitator is a kind of direct mixing equipment, the agitator is installed directly on the side wall of the container. It is good at stirs high viscosity materials, such as paints, resins and so on.

Side entry agitator

Side entry agitator 1 Side entry agitator is a device that inserts the side of the agitator into the container for mixing. It is suitable for large containers and high-viscosity liquids.
Side entry agitatorA variety of large tanks or storage tanks for mixing and stirring the medium. Especially using one or more side-entry agitators to work together.
 Flue gas desulphurisation to prevent solids from settling;
Heavy oil, gasoline and other petroleum products homogeneous mixing or mixing of various liquids;
Water treatment;
Biogas fermentation;

Top entry agitator

Top entry agitator Top entry agitator is a device that inserts the agitator from the top of the container for mixing. It mixes low-viscosity liquids in small containers.  Bottom-entry agitators are generally used in large-scale equipment, such as polymerization reactors, PVC mixing reactors, saccharification reactors, paste reactors, and other mixing operations.

As per shaft seal types:

Magnetic agitator

Magnetic agitator The left magnetic agitator picture shows how does the magnetic seal shaft look like after it was assembled on the reactor.
Magnetic agitators use the principle of magnetic field and vortex, the container of liquid to be stirred by sinking the stirrer is put on the base of the magnetic stirrer, when the magnetic stirrer is energized, a rotating magnetic field is generated near the base to drive the stirrer into a circular movement, and then a vortex is formed in the container of liquid, so as to achieve the purpose of stirring the liquid.
