[0002] Composite microgels, as a type of polymer material with unique properties, are widely used in biomedicine, cosmetics, coatings and other fields. In their preparation process, thorough mixing and uniform stirring of raw materials are key steps to ensure the stability of microgel performance.
[0003] Traditional mixers often have the following problems when processing composite microgel raw materials: First, the simple layout of the mixing blades makes it difficult to meet the mixing needs of the surface, middle and bottom layers of the material, resulting in uneven mixing; Second, the material tends to adhere and accumulate on the inner wall of the mixing tank, which not only affects the mixing effect, but may also cause abnormal local reactions of the raw materials and reduce product quality.

[0006] Preferably, the mixing tank is provided with a cleaning component, which includes a connecting rod. There are two sets of connecting rods, and the two sets of connecting rods are respectively fixedly connected to the outer ring wall of two sets of mounting bases. An arc-shaped scraper is fixedly connected to the end of the connecting rod.
[0007] Preferably, the arc-shaped scraper is spirally ascending, and both sets of arc-shaped scrapers are in contact with the inner wall of the mixing tank.
[0008] Preferably, a reinforcing rod is fixedly connected to the side wall of the stirring shaft, and the reinforcing rod is fixedly connected to the outer wall of the middle layer stirring blade.

[0012] Compared with the prior art, this utility model provides a stirrer for the preparation of composite microgels, which has the following beneficial effects:
[0013] 1. This mixer for preparing composite microgels utilizes a combination of wide-bladed fan-shaped upper impellers, spiral-shaped middle impellers, and serrated lower impellers. These different impeller shapes work together to achieve comprehensive mixing from the surface, middle, and bottom layers of the material. The upper impellers rapidly agitate the surface material, promoting initial mixing; the middle impellers facilitate longitudinal circulation of the material, ensuring thorough blending between the upper and lower layers; and the lower impellers provide strong shearing and mixing of the viscous material at the bottom, ensuring more thorough and uniform mixing of the composite microgel raw materials, thereby improving the preparation quality and performance stability of the composite microgels.
[0014] 2. The mixer used for the preparation of composite microgels uses a spiral-shaped arc scraper that rotates synchronously with the stirring shaft. This allows for timely scraping and stirring of materials near the barrel wall, preventing material from adhering and accumulating on the barrel wall. This further improves the uniformity of stirring, reduces material residue, lowers the difficulty and workload of subsequent cleaning, and improves the efficiency of equipment use. At the same time, it avoids product quality problems that may be caused by material residue, ensuring the hygiene and safety of the composite microgel preparation process. Attached Figure Description

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a mixer for preparing composite microgels, including a mixing tank 1. A support leg 11 is fixedly connected to the bottom of the mixing tank 1, supporting the entire mixing tank 1 and ensuring stable placement. A feed pipe 12 is fixedly connected to the top of the mixing tank 1, facilitating the input of raw materials required for composite microgel preparation into the mixing tank 1. A discharge pipe 13 is fixedly connected to the bottom of the mixing tank 1, and a solenoid valve 14 is installed on the outer wall of the discharge pipe 13. The solenoid valve 14 controls the opening and closing of the discharge pipe 13, facilitating the discharge of materials from the mixing tank 1 through the discharge pipe 13. A bracket 15 is fixedly connected to the mixing tank 1, and a guide plate 16 is fixedly connected to the bottom of the bracket 15. The guide plate 16 is positioned below the discharge pipe 13, smoothly guiding the discharged materials to subsequent processing equipment or storage containers.
[0021] like Figures 1-4As shown, a stirring assembly 2 is installed inside the stirring tank 1. The stirring assembly 2 includes a stirring shaft 21, which is rotatably connected to the inner wall of the stirring tank 1. A motor 22 is fixedly connected to the top of the stirring tank 1. The output shaft of the motor 22 passes through and is rotatably connected to the inner wall of the stirring tank 1. The output shaft of the motor 22 is fixedly connected to the end of the stirring shaft 21, driving the motor 22 to provide power for the rotation of the stirring shaft 21, thereby driving the entire stirring assembly 2 to operate. Two sets of symmetrically arranged mounting seats 23 are fixedly connected to the outer wall of the stirring shaft 21. Multiple sets of arrayed upper stirring blades 24 are fixedly connected to the outer ring wall of one set of mounting seats 23. The mixing blade 24 is a wide fan-shaped blade. Multiple arrays of lower mixing blades 25 are fixedly connected to the outer ring wall of another set of mounting bases 23. The side walls of the lower mixing blades 25 are serrated. A middle mixing blade 26 is fixedly connected between the two sets of mounting bases 23. The middle mixing blade 26 is arranged in two symmetrical spirals. The two sets of mounting bases 23 are used to fix and install the upper mixing blade 24, the lower mixing blade 25 and the middle mixing blade 26, so that the upper mixing blade 24, the lower mixing blade 25 and the middle mixing blade 26 rotate with the rotation of the mixing shaft 21 to stir the composite microgel raw material inside the mixing tank 1. The fan-shaped upper stirring blades 24 can quickly agitate the surface material, promoting initial mixing. The symmetrically arranged spiral-shaped middle stirring blades 26 push the upper composite microgel material downwards while simultaneously lifting the lower composite microgel material upwards, achieving longitudinal circulation of the material. The serrated lower stirring blades 25 can powerfully shear and stir the viscous material at the bottom, resulting in more uniform mixing. A reinforcing rod 27 is fixedly connected to the side wall of the stirring shaft 21, and the reinforcing rod 27 is fixedly connected to the outer wall of the middle stirring blades 26. The reinforcing rod 27 is used to reinforce the middle stirring blades 26, increasing their stability.
[0022] like Figures 1-4 As shown, a cleaning assembly 3 is installed inside the mixing tank 1. The cleaning assembly 3 includes two sets of connecting rods 31, which are fixedly connected to the outer ring walls of two sets of mounting seats 23. An arc-shaped scraper 32 is fixedly connected to the end of each connecting rod 31. The arc-shaped scraper 32 is spirally ascending, and both sets of arc-shaped scrapers 32 are in contact with the inner wall of the mixing tank 1. The arc-shaped scrapers 32 are connected to the mounting seats 23 via the connecting rods 31, allowing the mixing shaft 21 to drive the arc-shaped scrapers 32 to rotate synchronously during rotation. Because the arc-shaped scrapers 32 are in contact with the inner wall of the mixing tank 1, the composite microgel raw material near the tank wall can be stirred and scraped off, preventing material from adhering and accumulating on the tank wall, and further improving the uniformity of mixing.
[0023] In this invention, when in use, various raw materials required for the preparation of composite microgels are slowly fed into the mixing tank 1 through the feed pipe 12 according to the formula order and proportion.
[0024] When motor 22 is started, its output shaft drives the stirring shaft 21 to rotate. The upper stirring blade 24, middle stirring blade 26, and lower stirring blade 25 on the stirring shaft 21 begin to rotate synchronously. The upper stirring blade 24 rapidly stirs the surface material, initially mixing the raw materials. The middle stirring blade 26, through its spiral structure, pushes the upper material downwards while simultaneously lifting the lower material upwards, achieving longitudinal circulation of the material. The serrated sidewalls of the lower stirring blade 25 powerfully shear and stir the viscous material at the bottom, ensuring thorough and uniform mixing. During the stirring process, the arc-shaped scraper 32 of the cleaning component 3 rotates synchronously with the stirring shaft 21. Because it is in close contact with the inner wall of the mixing tank 1, it can continuously scrape and stir the material near the tank wall, preventing the material from adhering and accumulating on the tank wall, further improving the uniformity of the stirring.
[0025] Once the preset mixing time is reached and the materials are evenly mixed, stop the motor 22. Open the solenoid valve 14 on the outer wall of the discharge pipe 13, and the materials in the mixing tank 1 are discharged from the discharge pipe 13 under gravity. The discharged materials are guided by the guide plate 16 and flow smoothly into subsequent processing equipment or storage containers. After the materials are completely discharged, close the solenoid valve 14.
[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
