Description

Technical Field

[0001] This utility model relates to the field of emulsification equipment technology, specifically a mixing and stirring device for multiphase nano-homogeneous emulsification. Background Technology

[0002] Homogenization is a technique that uses physical means to bring a material system to a uniform state. It usually uses equipment such as homogenizers to apply high pressure, high shear force or ultrasound to the material. Emulsification is a technique that mixes immiscible liquids (such as oil and water) to form a stable emulsion. Through emulsification equipment, high pressure and high-speed shear are used to uniformly disperse one liquid in the form of tiny droplets in another liquid, so that nanoscale particles of different phases are uniformly dispersed in the medium. When homogenizing and emulsifying multiphase materials, mixing and stirring devices are used to stir and mix the materials of different phases.

[0003] Currently, when using a mixing and stirring device to emulsify multiphase materials, the materials to be emulsified are usually added directly into the mixing device through the feed port. However, the feed port is usually located on one side of the mixing device, which can easily cause the raw materials to concentrate on the feeding side in the initial stage and not be able to be quickly and evenly dispersed into the entire reaction vessel. This may result in excessively high raw material concentration in some areas and low concentration in other areas, affecting the uniformity and consistency of the reaction and the emulsification effect on the materials. Utility Model Content

This may result in excessively high raw material concentration in some areas and low concentration in other areas, affecting the uniformity and consistency of the reaction and the emulsification effect on the materials.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a multiphase nano-homogeneous emulsification mixing and stirring device, including a mixing and stirring chamber 1, an upper cover 16 fixedly installed on the upper surface of the mixing and stirring chamber 1, a rotor 2 rotatably installed on the lower surface of the upper cover 16, a stator 3 fixedly installed on the lower surface of the upper cover 16, and a feed pipe 4 fixedly installed on the upper surface of the upper cover 16, the lower end of the feed pipe 4 penetrating into the interior of the mixing and stirring chamber 1.

[0024] The dispersing mechanism is located inside the mixing chamber 1. The dispersing mechanism includes a rotating rod 5 and two beaters 6. The rotating rod 5 is rotatably mounted on the inner wall of the mixing chamber 1 and is located below the feed pipe 4. The two beaters 6 are fixedly mounted on the upper and lower ends of the rotating rod 5, respectively. The left surface of the two beaters 6 is provided with rectangular holes 7, and the right end of the two rectangular holes 7 is open. The inside of the rotating rod 5 is provided with rectangular grooves 8, and the rectangular grooves 8 are open on the top, bottom, left and right sides.

[0025] Furthermore, the dispersing mechanism also includes two dispersing nets 9, which are fixedly installed inside the two rectangular holes 7 respectively.

[0026] Furthermore, by setting up the rotating rod 5 and the two patting plates 6, the stirring motor 11 drives the rotating rod 5 and the two patting plates 6 to rotate, so that the two patting plates 6 pat and disperse the raw materials squeezed into the mixing chamber 1, thereby making the raw materials enter the mixing chamber 1 more evenly, thus improving the uniformity and consistency of the reaction, and improving the emulsification effect of the mixing device on the materials.

[0027] Furthermore, a mounting plate 10 is fixedly installed on the right end of the front surface of the mixing chamber 1, and a dispersing motor 11 is fixedly installed on the front surface of the mounting plate 10. The output end of the dispersing motor 11 rotates through into the interior of the mixing chamber 1, and the dispersing motor 11 is fixedly connected to the rotating rod 5.

[0028] Furthermore, a stirring motor 12 is fixedly installed on the upper surface of the cover 16. The output end of the stirring motor 12 rotates through the interior of the mixing chamber 1, and the stirring motor 12 is fixedly connected to the rotor 2.

[0029] Furthermore, a reinforcing block 13 is fixedly installed inside the rectangular groove 8.

[0030] Furthermore, a cover 14 is threaded onto the upper end of the feed pipe 4, and a shear head 15 is fixedly installed on the upper end of the outer surface of the rotor 2.

[0031] Furthermore, when using this device, firstly, open the cap 14 at the upper end of the feed pipe 4, and add the multiphase nanomaterials that need to be homogenized and emulsified into the mixing chamber 1 through the feed pipe 4. The feed pipe 4 serves to guide the raw materials into the device. The added raw materials will first fall onto the rotating rod 5 and the beater plate 6 located below the feed pipe 4. At this time, start the dispersion motor 11 installed on the mounting plate 10. The output end of the dispersion motor 11 drives the rotating rod 5 to rotate, and the beater plates 6 at the upper and lower ends of the rotating rod 5 rotate accordingly. When the raw materials come into contact with the beater plates 6, the beater plates 6 perform initial beating and dispersion of the raw materials, beating some of the raw materials to the left side of the mixing chamber 1. At the same time, the dispersion mesh 9 in the rectangular hole 7 on the beater plate 6 further disperses the raw materials, and allows another part of the raw materials to pass through the rectangular hole 7 and the rectangular mesh 9 in the rotating rod 5. The trough 8 falls to the right side of the mixing chamber 1, allowing the raw materials to enter the interior of the mixing chamber 1 more evenly. The reinforcing block 13 inside the rotating rod 5 enhances the structural strength of the rotating rod 5. Then, the stirring motor 12 on the top cover 16 is started. The stirring motor 12 drives the rotor 2 to rotate. The rotating rotor 2 cooperates with the stator 3 to perform homogenization and emulsification treatment on the dispersed raw materials. The shear head 15 at the upper end of the outer surface of the rotor 2 can further disperse the raw materials falling on the shear head 15 when the raw materials are hit to the left by the patting plate 6. This can better mix and refine the different phases in the raw materials, achieving a nano-level homogenization and emulsification effect.
