Description

Technical Field

[0001] This utility model relates to a dispersion device for wear-resistant and highly hydrophobic coating materials. Background Technology

[0002] Currently, the dispersion stage is crucial in the preparation of wear-resistant and highly hydrophobic coating materials. Most commercially available dispersion devices for coating materials employ traditional stirring structures, with relatively simple stirring unit designs. Typically, the blades in each stirring unit are tilted in the same direction or simply randomly, failing to create complex and effective turbulence. This results in insufficient exchange and mixing of coating materials in different areas within the dispersion tank, easily leading to uneven dispersion. Therefore, developing a dispersion device for wear-resistant and highly hydrophobic coating materials that can effectively solve the above problems is of significant practical importance. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a dispersion device for wear-resistant and highly hydrophobic coating materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a dispersion device for wear-resistant and highly hydrophobic coating materials, comprising a dispersion tank and a stirring device disposed within the dispersion tank, wherein the stirring device comprises a rotating shaft and at least three stirring units, wherein each stirring unit is spaced apart along the axial direction of the rotating shaft, and each stirring unit comprises a hub and at least two blades disposed around the hub, wherein the angle between the blades and the axis of the hub is 30° to 60°.

[0005] In two adjacent mixing units, the blades of one mixing unit are tilted clockwise, and the blades of the other mixing unit are tilted counterclockwise.

[0006] Further improvements include staggered blades on the circumference of the shaft between two adjacent stirring units.

[0007] Further improvements were made, with the spacing between two adjacent stirring units gradually decreasing from top to bottom.

[0008] In a further improvement, the inner wall of the dispersion tank is provided with a hydrophobic coating, which is a polytetrafluoroethylene or nano-silica composite coating with a thickness of 10-50 μm.

[0009] In a further improvement, the ratio of the radius of the stirring unit to the radius of the dispersion tank is set to 0.35 to 0.65.

[0010] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This utility model, by setting at least three stirring units spaced apart along the axial direction of the rotating shaft and with the blades alternately tilted upwards and downwards, can create complex turbulence in the coating material within the dispersion tank, enhancing the exchange and mixing of materials at different levels and improving the dispersion effect. Furthermore, the blades of two adjacent stirring units are staggered circumferentially along the rotating shaft, further enhancing the turbulence of the coating material within the dispersion tank, allowing for more thorough mixing of the material components. Furthermore, since the required stirring force varies at different stages during the dispersion process, the material is relatively dispersed when it first enters the dispersion tank, allowing for a slightly larger spacing between stirring units. As dispersion progresses and the material gradually mixes, more intensive stirring is required; therefore, the spacing between adjacent stirring units gradually decreases from top to bottom to prevent uneven dispersion and clogging of the dispersion tank. Furthermore, the wear-resistant, highly hydrophobic coating reduces the adhesion of the coating material to the inner wall of the dispersion tank, facilitating cleaning and increasing the service life of the dispersion tank. Furthermore, setting the ratio of the radius of the stirring unit to the radius of the dispersion tank to 0.35–0.65 is beneficial for forming a reasonable flow field, improving dispersion efficiency and quality.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] refer to Figure 1-3 This embodiment provides a dispersion device for a wear-resistant and highly hydrophobic coating material, including a dispersion tank 1 and a stirring device 2 disposed within the dispersion tank 1. The dispersion tank 1 is a cylindrical container made of stainless steel, which has good strength and corrosion resistance and can withstand various forces during the dispersion process of the coating material. The stirring device 2 is installed at the center of the dispersion tank 1 and is connected to a drive mechanism outside the dispersion tank 1 via a rotating shaft 21 to achieve the stirring function.

[0018] The stirring device 2 includes a rotating shaft 21 and at least three stirring units 22. In this embodiment, four stirring units 22 are provided, and each stirring unit 22 is spaced apart along the axial direction of the rotating shaft 21. The ratio of the radius of the stirring unit 22 to the radius of the dispersion tank 1 is set to 0.35 to 0.65. This ratio range is beneficial for forming a reasonable flow field and improving dispersion efficiency and quality. The spacing between two adjacent stirring units 22 gradually decreases from top to bottom. This is because the required stirring force varies at different stages during the dispersion process of the coating material. When the material first enters the dispersion tank 1, it is relatively dispersed, and the spacing between the stirring units 22 can be slightly larger. As dispersion progresses, the material gradually mixes, requiring more intensive stirring. Therefore, the smaller spacing can prevent uneven dispersion and clogging of the dispersion tank 1.

[0019] The stirring unit 22 includes a hub 221 and at least two blades 222 disposed around the hub 221. In this embodiment, there are three blades 222. The hub 221 has a circular structure and is connected to the rotating shaft 21 by a known key to ensure that the stirring unit 22 can rotate with the rotating shaft 21. The diameter of the hub 221 is designed according to the size of the stirring unit 22 and the number of blades 222 to ensure the installation stability of the blades 222 and the stirring effect. The angle between the blades 222 and the axis of the hub 221 is 30° to 60°. In this embodiment, in two adjacent stirring units 22, the blades 222 of one stirring unit 22 are inclined clockwise, and the blades 222 of the other stirring unit 22 are inclined counterclockwise. This arrangement enables the coating material in the dispersion tank 1 to form complex turbulence, enhances the exchange and mixing of materials at different levels, and improves the dispersion effect. Meanwhile, the blades 222 of the two adjacent stirring units 22 are staggered upward around the rotating shaft 21, which can further enhance the turbulence of the coating material in the dispersion tank 1 and make the components of the material mix more thoroughly.

[0020] The inner wall of the dispersion tank 1 is provided with a hydrophobic coating 11, which is a composite coating of polytetrafluoroethylene or nano-silica with a thickness of 10-50 μm. This hydrophobic coating 11 can reduce the adhesion of coating materials to the inner wall of the dispersion tank 1, making it easier to clean and improving the service life of the dispersion tank 1.

[0021] In operation, the wear-resistant, highly hydrophobic coating material to be dispersed is first added to the dispersion tank 1. Then, the external drive mechanism is activated, driving the rotating shaft 21 to rotate, which in turn drives the stirring unit 22 of the stirring device 2 to rotate. During rotation, the blades 222 of the stirring unit 22 stir and disperse the coating material. Due to the special design of the stirring unit 22, the coating material forms complex turbulence within the dispersion tank 1, allowing for thorough exchange and mixing of materials at different levels, thus achieving uniform dispersion. During dispersion, the hydrophobic coating 11 effectively reduces the adhesion of the coating material to the inner wall of the dispersion tank 1, ensuring smooth dispersion. After dispersion is complete, the drive mechanism is stopped, and the discharge port of the dispersion tank 1 is opened to discharge the dispersed coating material.
