[0002] In the production process of highly hydrophobic nanocomposite fluorocarbon coatings, the uniform dispersion of the coating components is crucial. The characteristics of highly hydrophobic nanoparticles make them prone to aggregation. If the dispersion is poor, it will seriously affect the performance of the coating, such as corrosion resistance and stability. Traditional dispersion equipment and processes have many shortcomings when dealing with this type of coating.

[0003] Existing dispersion equipment has shortcomings in cleaning. The coating tends to adhere to the inner wall of the cylinder, requiring additional cleaning tools. Furthermore, the large size of the cylinder makes operation inconvenient, leading to cumbersome cleaning, material waste, and the residual coating affecting the quality of the next batch of products. The cleaning process is tedious and time-consuming, increasing production costs. Therefore, a dispersion machine with a strong hydrophobic nano-composite fluorocarbon coating is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a disperser for a highly hydrophobic nanocomposite fluorocarbon coating, comprising a cylinder 1. The cylinder 1 is used to process and disperse the highly hydrophobic nanocomposite fluorocarbon coating, and serves as the main structure of the disperser. It is typically made of a high-strength, corrosion-resistant metal material, such as stainless steel. A dispersion disc 2 is installed inside the cylinder 1. The high-speed rotation of the dispersion disc 2 causes the coating to diffuse outwards under centrifugal force. Simultaneously, the texture and protrusions on its surface cut and stir the coating, breaking large particles into smaller ones, promoting uniform dispersion of nanoparticles in the coating, and improving... To ensure the dispersion quality and stability of the coating, a dispersion mechanism is installed inside the cylinder 1. The dispersion mechanism includes a cleaning component 3, which includes two sets of scrapers 31 that are fitted and slidably connected to the inner wall of the cylinder 1. The scrapers 31 are made of highly elastic and wear-resistant rubber material. This material can ensure a tight fit with the inner wall of the cylinder 1, effectively removing the coating adhering to the wall surface, and is not easily damaged during long-term friction. The bottom ends of the two sets of scrapers 31 are fixedly connected to horizontally arranged guide rods 34. The guide rods 34 provide stable support and guidance for the scrapers 31. At the same time, the top two sides of the guide rods 34 are inclined surfaces, which can reduce the resistance during stirring and rotation.

[0031] Furthermore, a drive rod 33 is fixedly connected to the bottom middle of the guide rod 34, which drives the guide rod 34 to rotate. A servo motor 32 is fixedly connected to the bottom of the drive rod 33, which drives the drive rod 33 to rotate. The servo motor 32 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The speed or output torque of the servo motor 32 can ensure the coordinated movement of the guide rod 34 and the rotating rod 41. By controlling the speed of the servo motor 32, the dispersing disk 2 can be assisted in dispersing. The servo motor 32 is fixedly installed at the bottom of the cylinder 1 by bolts. A guide ring 35 is fixedly connected to the middle of the guide rod 34 near the scraper 31. The guide ring 35 serves to separate the internal space of the cylinder 1. A disc 36 is set in the middle of the cylinder 1 at the middle of the guide ring 35. The guide rod 34 and the disc 36 provide a stable support surface for the guide ring 35. The guide ring 35 is rotatably connected to the guide rod 34. Between the inner wall of the bottom end of the cylinder 1 and the outer wall of the disc 36, the guide rod 34 is slidably connected to the inner wall of the bottom end of the cylinder 1 and the top end of the disc 36. The inner sides of both sets of scrapers 31 are set as inclined surfaces. When the scraper 31 moves, it can guide the scraped paint into the inside of the cylinder 1, avoiding paint accumulation between the scraper 31 and the wall of the cylinder 1, which would affect the cleaning effect. The top end of the guide rod 34 is set as an inclined surface, which can reduce the resistance to the paint during the movement and make the cleaning process smoother.

[0032] Reference Figure 2 , Figure 3 and Figure 4 The dispersing mechanism also includes a stirring assembly 4, which includes two sets of rotating rods 41 supporting multiple sets of stirring blades 42. The two sets of rotating rods 41 pass through the top of the guide ring 35 and are rotatably connected to it. Multiple sets of stirring blades 42 are fixedly connected to the outer walls of the two sets of rotating rods 41 and are evenly distributed vertically. The stirring blades 42 adopt a special turbine shape and the blades of the stirring blades 42 are inclined, which can reduce the resistance of stirring and improve the stirring effect. Under the drive of the rotating rods 41, the coating can be strongly stirred and mixed.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The cylinder 1 is equipped with a transmission assembly 5, which includes two sets of gears 51 that drive the rotating rod 41 and the stirring blade 42 to rotate. The two sets of gears 51 are fixedly connected to the bottom ends of the two sets of rotating rods 41 and are located inside the placement groove 54. The bottom end of the cylinder 1 is provided with a placement groove 54 to provide space for operation. A gear 53 is fixedly connected to the middle of the bottom inner wall of the placement groove 54. The gear 53 meshes with the gear 51. When the gear 51 rotates, it meshes with the gear 53, which allows the gear 51 to rotate. The top end of the gear 53 is fixedly connected to a fixing rod 52 that connects the gear 53 to the disc 36 for support. The top end of the fixing rod 52 is fixedly connected to the bottom end of the disc 36. The drive rod 33 passes through the placement groove 54 and the disc 36 and is rotatably connected to the disc 36. The two sets of gears 51 are meshed on the left and right sides of the gear 53.

[0034] Working principle: When in use, after the power is turned on, the dispersion disk 2 starts to rotate at high speed. Due to the special texture and protrusions on the surface of the dispersion disk 2, the strong centrifugal force under high speed causes the coating to spread in all directions. At the same time, the texture and protrusions on the surface cut and stir the coating, breaking large particles into fine particles, laying the foundation for the uniform dispersion of nanoparticles in the future, and initially improving the dispersion quality and stability of the coating.

[0035] When the servo motor 32 is started, its output shaft drives the drive rod 33 to rotate. The drive rod 33 drives the guide rod 34 to move in a circular motion around the central axis of the cylinder 1. The guide rod 34 drives the two sets of scrapers 31 to move synchronously. The scrapers 31 scrape off the paint adhering to the inner wall of the cylinder 1. The inclined design on the inner side of the scraper 31 allows the scraped paint to be guided into the inside of the cylinder 1, avoiding accumulation between the scraper 31 and the wall of the cylinder 1, which would affect the cleaning effect. The inclined surface at the top of the guide rod 34 reduces the resistance to the paint during the movement, making the cleaning process smoother and thus effectively cleaning the inner wall of the cylinder 1.

[0036] As the guide rod 34 moves, the guide ring 35 rotates, and the two sets of rotating rods 41 connected to it rotate synchronously. The turbine-type stirring blades 42, which are evenly distributed on the outer wall of the rotating rods 41, rotate together with the rotating rods 41. Driven by the rotating rods 41, the turbine-type stirring blades 42 strongly stir and mix the coating, generating strong shear force and flow field. This assists the dispersion disk 2 in further promoting the uniform dispersion of various components in the coating, especially the uniform distribution of nanoparticles in the fluorocarbon coating, thereby improving the overall dispersion effect of the coating.

[0037] Simultaneously, when the rotating rod 41 rotates, it drives the corresponding two sets of gears 51 to rotate. The two gears 53 mesh with the two sets of gears 51 on the left and right sides respectively. Therefore, through meshing, the two sets of gears 51 can rotate while rotating, causing the rotating rod 41 and the stirring blade 42 to rotate. Thus, the coating can be cut and stirred by the high-speed rotation of the dispersing disc 2, breaking large particles into small particles. With the auxiliary rotation of the stirring blade 42, the coating can be continuously and stably stirred, enhancing the uniformity of dispersion and improving the dispersion effect. After a period of operation, when the coating reaches the expected dispersion effect, the disperser is turned off, the discharge valve at the bottom of the cylinder 1 is opened, and the dispersed strong hydrophobic nano-composite fluorocarbon coating is discharged from the discharge port, completing the entire dispersion process.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
