Submersible Mixer

Stirrer – mixer is a large capacity machine, using 3-phase current, high cost, durable materials. Mainly used for stirring paint, stirring food, stirring powder, stirring waste, stirring glue, malt…. Another name of the machine is industrial mixer.

The mixer is powerful, stable, solidly designed, professional, has a wide range of applications. The current mainstream applications are in all manufacturing industries including applications of powder agitators, mixing paints, glues, chemicals, solvents, etc., high viscosity solutions.

Agitator-mixer is a mechanical device used to agitate in tanks containing slurries and other materials. Mixers are commonly used in wastewater treatment plants to keep solids in suspension (suspended) in different treatment tanks.

In industry, agitators come in many different configurations and shapes. Suitable for a variety of mixing applications. To understand more details, we continue to follow the content below.

I will share the characteristics, structure, and applications of mixers in hot industries such as food, chemicals…

Features of industrial mixers

Mixers are currently used a lot in education, experiments…and most often in the F&B and cosmetic industries…Some outstanding features of the stirrer – mixer line are as follows:

    • The industrial mixer is integrated with automatic lifting mechanism by hydraulic system ⇒ Extremely convenient to use during mixing
    • Has a large capacity, powerful
    • The machine’s models are extremely diverse with a wide capacity range ⇒ Meet a variety of stirring solutions with different viscosities
    • Use inverter to adjust the stirring speed easily
    • Use a standard designed dispersion impeller
    • Fast, even, powerful stirring force
    • The imported motor is completely durable, smooth, and vibration-free High-quality stirrer material with good bearing, high corrosion resistance: Shaft, coupling, stirrer stainless steel 304, 316

Structure of mixer

Looking at the outside overview, we see that a basic mixer seems very simple. But in terms of components, they include:

    • Motor
    • Box Reduce speed
    • Axis
    • Stirrer blade

In it, specifically:

    • Motor: The part that converts electrical energy into mechanical energy. Acts on the impeller through a rotating shaft that is directly connected to the motor. A motor can be turned on/off without speed control mode. Or use the inverter to adjust the speed as well as the rotational force of the motor in the application of stirring paint, powder, plastic, …
    • Gearbox: This is a solution to use for applications requiring slow stirring speed but strong stirring force. Similar to inverters, reducers are used in many applications where the viscosity is high.
    • Agitator shaft: An extension part, connecting the motor shaft and agitator. The part is in direct contact with the material in the stirring tank. Therefore, they often have a structure of good, non-rusting, non-corrosive materials like stainless steel 3-4, 316…
    • Agitator: There are many different types, but usually there are 2 main types: propeller and paddle. Similar to the stirrer shaft, the stirring impeller is also made of stainless steel 304, 316…for chemical stirring applications…

Types of mixer

Mixers are divided into several types. And each will be used for a few different specialized applications. Eg:

Submersible mixers are submerged in the stirring medium. To optimize material stirring efficiency. But the disadvantage is that it is more difficult to check, maintain and maintain. And usually, very few applications use this method.

Shaft-coupled mixers: The most common type, available in many different capacities, suitable for many applications from as small as in a laboratory, to as large as a production industrial mixer… They include Tanks that can be stainless steel, plastic, or glass for the application. And there is also a frame to support the motor, holding the stirrer in place, to increase the efficiency of the application.

In addition, people often rely on the application to choose the type of stirrer quickly. For example: Choose chemical mixer, paint stirrer, powder stirrer…

Types of mixer blades

As well as the classification of agitators. Then when classifying stirrer blades, we are mainly based on their characteristics and popularity. Currently, on the market, there are many types of agitators such as anchors, oars, turbines, propellers, … but there are mainly 2 main types of rotors that are used a lot, which are:

Propeller mixer

Propeller stirrers are common, they are shaped like actual propellers. They are often found in the oars of boats…

A special feature of the propeller stirrer is that it has 3 blades. The easiest to see is on the fan in your home. They usually have a large, rounded wing shape and are thinner than a paddle. And they usually produce axial flow. Therefore, the flow generated by the propeller agitator is superior to other types of a stirrer.

Paddle mixer

There are also different types of paddle mixers. Can be in the form of 2-blades, 3-blades, 4-blades, and 5-blades… The advantage of this type of mixer is that it creates a high-speed flow, creating high disturbances… We will rely on characteristics such as:

    • Wing size
    • Wing shape
    • Thickness of impeller
    • Made of what material?
    • Shaft connection by screw thread or pin?

But in addition, people also rely on the type of flow generated to classify the stirrer. In this case, we have:

A popular type of mixer

    • The impeller creates an axial flow
    • Agitator creates a radial flow

Note when choosing a mixer

Thai Khuong shares with you a few notes when choosing to buy a mixer for the purpose of use.

When learning to choose to buy a mixer, you should note a few features such as:

    • Materials to be mixed
    • What is the volume of a batch of mixing?
    • The material form of impeller and shaft
    • Choose the form of shaft stirring or sinking
    • Continuous or intermittent mixing model…

Application of mixer

The mixer is widely used in industry. They are used as an alternative to labor, freeing up human energy. Especially in hazardous environments such as chemical experiments…

Agitators are commonly found in the mixing of materials. Create a uniform, even mixture in the production and processing of confectionery and food.

Application of mixer
Application of mixer

Creating suspensions, dissolving chemicals in waste treatment.

We can list some typical applications such as:

    • Paint stirrer
    • Dough stirrer
    • Chemical stirrer
    • Cosmetic stirrer
    • Glue stirrer
    • Heated magnetic stirrer…

What is a variable frequency drive?

Biến tần máy bơm

VFDs control motor speed by varying the voltage and frequency applied to the stator of a standard AC motor. VFDs can vary speed control at startup, during the run, and at the motor stop. A standard AC motor has a published efficiency and power factor. They are quite high, typically well above 90%, but only …
