Jet-type intermittent high-shear emulsifying machine

Jet-type Intermittent High-shear Emulsifier

Product Introduction:

Jet-type Intermittent High-shear Emulsifier is developed based on ordinary high-shear emulsifiers and combined with axial flow requirements. Its special stirring head structure integrates four functions: dispersion, dissolution, emulsification, and crushing, which can effectively solve mixing problems for you. The precise cooperation between the rotor and stator ensures that the processed material is subjected to hundreds of thousands of high-speed shears per minute. The change of 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 the scope of application. 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 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-type rotor have an oblique angle with the axis. Therefore, 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 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.

Stator hole forms include:

Features of the perforated and slotted diversion stator: It has both radial shear, emulsification and homogenization dispersion effects, as well as axial jet function, which is an organic combination of local micro and overall macro effects.

1. Mesh hole (good fineness, suitable for materials with lower viscosity);
2. Straight slot (fair fineness, suitable for materials with medium and low viscosity);
3. Inclined slot (fair fineness, suitable for materials with medium and low viscosity, with the smallest radial flow pulsation);
4. Large hole (slightly poor fineness, suitable for materials with higher viscosity) and other forms.

Working heads with different functions:

Features of the non-perforated and slotted diversion stator: Single axial flow, no shear force is generated, ensuring energy concentration and generating strong jet flow. It is suitable for working conditions where mixing, dispersion, dissolution, suspension, reaction acceleration, and no further requirements on fineness are needed.

The liquid flow has no vortex, no sediment at the bottom of the container, can protect the integrity of particles, has small 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, crushing, 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. It integrates new scientific and technological achievements based on traditional models and has made many humanized adjustments:

1. The mobile frame is equipped with caster brakes to make 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. Dispersion wheels 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, and can also independently complete various processes.

Containers are divided into two types: normal 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 Sequence:

When using a jet emulsifier, the material feeding sequence is as follows:

① Add all components with the lowest viscosity to the container and start mixing.
② Add the remaining liquid 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.
