Pilot-scale jet dispersion mixer

Pilot-scale Jet Flow Dispersion Mixer

Product Introduction:

The Pilot-scale Jet Flow Dispersion Mixer is developed based on ordinary high-shear emulsifiers combined with axial flow requirements. Its special stirring head structure integrates four functions: dispersion, dissolution, emulsification, and pulverization, which can effectively solve your mixing problems. The precise cooperation between the rotor and stator ensures that the processed material undergoes hundreds of thousands of high-speed shears per minute. The change in blade angle achieves the dual effects of radial flow and axial flow. Stator head forms such as straight slots, inclined slots, and mesh holes expand its application fields. It is widely used in light industry and chemical industries such as daily chemicals, pharmaceuticals, food, textiles, printing and dyeing, and coatings.

The intermittent jet emulsifier can be installed on a mobile frame, lifting frame, reaction kettle or other containers as needed to meet different production process requirements. Stator heads of different shapes have different emulsification, dispersion and mixing effects. According to the actual working conditions, different types of stator heads can be selected to meet the needs of different processes.

Working Principle:

The blades of the jet rotor are inclined at an angle to the axis, so when rotating at high speed, it generates both radial centrifugal force and axial thrust on the fluid. When combined with the stator, it forms a radial shear, dispersion and emulsification effect. At the same time, the axial flow enhances the large circulation of the fluid in the kettle, effectively eliminating the "unevenness or blind spots" in the initial stage of emulsification and dispersion. When the viscosity is medium and low and the power is sufficient, the anchor paddle auxiliary stirring can be omitted, saving equipment investment.

Types of stator holes include:

Stator with perforated slots: It has both radial shear, emulsification, homogenization and dispersion effects, as well as axial jet function, which is an organic combination of local micro and overall macro effects.

1. Mesh holes (good fineness, suitable for low-viscosity materials);

2. Straight slots (fair fineness, suitable for medium and low-viscosity materials);

3. Inclined slots (fair fineness, suitable for medium and low-viscosity materials, with minimal radial flow pulsation);

4. Large holes (slightly poor fineness, suitable for high-viscosity materials) and other forms.

Working heads with different functions:

Stator without perforated slots: It has a single axial flow and does not generate shear force, ensuring energy concentration and generating a strong jet. It is suitable for working conditions where there is no further requirement for fineness, such as mixing, dispersion, dissolution, suspension, and accelerated reactions.

The liquid flow has no vortex, no sediment at the bottom of the container, can protect the integrity of particles, has low air infiltration, and is more efficient and easier to prepare suspensions.

Mobile Jet Emulsifier:

Suitable for simple operations in multiple open containers. It can independently complete processes such as mixing, emulsification, homogenization, pulverization, and reaction on different containers. Cleaning can be done during the interval of each batch of material processing. The processing capacity per batch ranges from 15 liters to 20,000 liters, and the power ranges from 1.1KW to 75KW.

The mobile emulsifier has the ability to work in different environments, so its application range is extremely wide. Yuedi timely integrates new scientific and technological achievements on the basis of traditional models and has made many humanized adjustments:

1. The mobile frame is equipped with caster brakes, making the machine run more stably and safely;

2. Hydraulic, pneumatic, and electric lifting, with various forms;

3. Special sliding bearings can be selected, which are acid-resistant, wear-resistant, and have a longer service life;

4. Wear-resistant shaft sleeves can be selected to protect the main shaft and reduce maintenance costs;

5. A dispersion wheel can be selected to improve the comprehensive emulsification and dispersion ability;

6. Long holes, round holes, mesh holes, straight slots, and inclined slots can be selected;

7. Explosion-proof motors, variable frequency motors, frequency converters, and electric control boxes can be equipped;

8. Industrial high-speed jet emulsifiers that can operate above 50Hz can be customized.

Fixed Jet Emulsifier:

Suitable for fixed operations on a single container, it can also independently complete various processes.

Containers are divided into two types: atmospheric pressure and pressure-bearing. According to different process requirements, coil pipes and jacket heating forms are equipped.

In addition to the ordinary type, fixed jet emulsifiers also have other types:

1) Fixed emulsifiers with oil seal, mechanical seal, water seal and magnetic seal can meet various working conditions requiring sealing;

2) Emulsifiers with dispersion wheels: Dispersion wheels are installed below or above the shear rotor and stator to enhance the dispersion effect;

3) Wear-resistant rotors and stators: Made of special alloy steel, they are wear-resistant, acid-resistant, impact-resistant, and have a long service life.

Recommended Feeding Process:

When using a jet emulsifier, the recommended material supply process is as follows:

① Add all components with the lowest viscosity to the container and start mixing.

② Add the remaining liquids or soluble components.

③ Add solids that require vigorous mechanical stirring or solids that require a certain period of chemical reaction.

④ Add the remaining solids, including solids used to build viscosity or stabilize the formula.
