Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of nano emulsion preparation production, and specifically relates to a device for precisely regulating and controlling the particle size of nano emulsion. BACKGROUND

[0002] The emulsification process is essentially a process of crushing insoluble solids or liquids into particles and fully mixing them with the surrounding liquid to form emulsion. Nano emulsion is divided into three types, namely oil-in-water nano emulsion (O / W), water-in-oil nano emulsion (W / O) and double-continuous nano emulsion (B.C). Emulsification can be roughly divided into two categories, namely mechanical method and physical and chemical method. Nano emulsion is a non-equilibrium system, and its formation requires external energy, which generally comes from mechanical equipment or from the structural potential of chemical agents. The energy of mechanical equipment (high-speed stirrer, high-pressure homogenizer) is generally considered to be a high-energy emulsification method. The method using the chemical potential in the structure is generally considered to be a concentration method or a low-energy emulsification method.

[0003] The traditional high-speed stirrer production method is to place the dispersed material and the continuous material in a high-speed device for continuous stirring to form nano emulsion. The particle size of the nano emulsion formed by stirring is difficult to control, which is not convenient for the production of nano emulsion products with specific particle size. Moreover, the dispersed phase material and the continuous phase material are placed together for stirring, and the nano emulsion formed has poor emulsification effect. CONTENT OF THE UTILITY MODEL

[0034] Embodiment 1

[0035] Referring to the drawings Figs. 1-3 The device for accurately regulating the particle size of nanoemulsion of the present embodiment comprises a particle size accurate regulation unit 100, and the particle size accurate regulation unit 100 is connected with a continuous phase tank 200 and a dispersed phase tank 300 through pipelines respectively.

When the worker places the continuous phase material in the continuous phase tank 200, the drive motor is started. The drive motor drives the stirring shaft to rotate through a speed reducer. The stirring blades are fixed on the stirring shaft and rotate with the stirring shaft. The continuous phase material is stirred and dissolved to generate the continuous phase, which is stored. The stirring blades are specially designed with multiple angles and multiple layers to increase the stirring effect and mixing uniformity. The speed of the drive motor is 0-5000 rpm.

[0037] The dispersed phase tank 300 is used to stir and dissolve the dispersed phase material to generate the dispersed phase and store the dispersed phase. The dispersed phase can be an aqueous phase or an oil phase. The dispersed phase tank 300 is provided with a drive motor, a stirring shaft and stirring blades. When the worker places the dispersed phase material in the dispersed phase tank 300, the drive motor is started. The drive motor drives the stirring shaft to rotate through a speed reducer. The stirring blades are fixed on the stirring shaft and rotate with the stirring shaft. The dispersed phase material is stirred and dissolved to generate the dispersed phase, which is stored. The stirring blades are specially designed with multiple angles and multiple layers to increase the stirring effect and mixing uniformity. The speed of the drive motor is 0-5000 rpm.

[0038] The particle size precision control unit 100 includes a particle size control module 110, which includes a metal diaphragm 111 and a diaphragm hole 112. The particle size control module 110 is used to mix the dispersed phase and the continuous phase to generate a nanoemulsion product with a specific particle size. The nanoemulsion product can be a water-in-oil nanoemulsion or an oil-in-water nanoemulsion. The particle size control module 110 is provided in multiple groups, and the multiple groups of particle size control modules 110 are connected in series or parallel through pipelines. The particle size control module 110 is connected to a collection tank 500, which is used to store the nanoemulsion product with a specific particle size.

[0039] It also includes a diaphragm pump 600 and a peristaltic pump 700. The diaphragm pump 600 is arranged in the pipeline connecting the dispersed phase tank 300 and the particle size control module 110. The diaphragm pump 600 is used to transport the dispersed phase stored in the dispersed phase tank 300 to the particle size control module 110. The peristaltic pump 700 is arranged in the pipeline connecting the particle size control module 110 and the continuous phase tank 200. The peristaltic pump 700 is used to transport the continuous phase stored in the continuous phase tank 200 to the particle size control module 110.

[0040] The air compressor 400 is also included, which is connected with the pipeline connecting the dispersed phase tank 300 and the particle size control module 110, and forms high pressure through compressed air, which on one hand accelerates the dispersed phase delivered from the dispersed phase tank 300 to the particle size control module 110 to collide with the continuous phase to form the primary emulsion, and on the other hand extrudes the primary emulsion through the diaphragm hole 112 to produce the nanoemulsion product with specific particle size, and the pressure generated by the air compressor 400 ranges from 0 to 0.9 MPa.

[0041] The diaphragm holes 112 are arranged on the metal diaphragm 111 in an array, and the diameter of the diaphragm hole 112 is d, which ranges from 1 nm to 100 nm, and the dispersed phase delivered from the dispersed phase tank 300 and the continuous phase delivered from the continuous phase tank 200 are mixed in the particle size control module 110 to form the primary emulsion, which is extruded through the diaphragm hole 112 to form the nanoemulsion product with specific particle size.

[0043] Specifically, when a 20 nm nanoemulsion product is needed, three groups of the metal diaphragm 111 are arranged in the particle size control module 110, and the three groups of the metal diaphragm 111 are arranged in the vertical direction of the particle size control module 110, and the diameter of the diaphragm hole 112 arranged on the upper metal diaphragm 111 is 50 nm, the diameter of the diaphragm hole 112 arranged on the middle metal diaphragm 111 is 35 nm, and the diameter of the diaphragm hole 112 arranged on the lower metal diaphragm 111 is 20 nm. When the air compressor 400 generates high pressure through compressed air, the primary emulsion formed in the particle size control module 110 is extruded through the upper metal diaphragm 111 to generate 50 nm nanoemulsion product, and when the 50 nm nanoemulsion product is extruded through the middle metal diaphragm 111, the 50 nm nanoemulsion product generates 35 nm nanoemulsion product, and when the 35 nm nanoemulsion product is extruded through the lower metal diaphragm 111, the 35 nm nanoemulsion product generates the final 20 nm nanoemulsion product.
