Description

Technical Field

[0001] This utility model relates to the field of suspension production technology, and in particular to a shear emulsification homogenization and dispersion device for pesticide suspensions. Background Technology

[0002] Pesticide products include various formulations such as aqueous solutions, powders, emulsions, and suspensions. Among them, suspensions are a type of formulation made by dispersing solid active pharmaceutical ingredients (APIs) particles in water. When the API used in pesticides is a solid that is insoluble or slightly soluble in water, preparing it into a suspension is currently a better solution. It has the advantages of being dust-free and solvent-free, and is more friendly to workers and the environment.

[0003] Traditional equipment often relies on a single stirring or vibration method, lacking the synergistic effect of macroscopic flow and strong microscopic shearing. Stirring alone can easily create mixing dead zones and cannot effectively overcome the sedimentation tendency of particles in high-solids-content suspensions; shaking alone is insufficient to provide enough shear force to achieve fine emulsification and homogeneous dispersion. Therefore, a shear emulsification and homogeneous dispersion device for pesticide suspensions is provided to solve the above problems. Utility Model Content

[0024] Reference Figures 1 to 4 In this embodiment of the invention, the pesticide suspension shear emulsification homogenization and dispersion device includes:

[0025] Dispersion tank 1;

[0026] The barrel shaking mechanism 2 is located below the dispersing barrel 1 and is used to make the dispersing barrel 1 shake evenly in a circular motion.

[0027] Emulsification and dispersion mechanism 3 is located above dispersion tank 1 and is used to shear and emulsify the pesticide suspension inside dispersion tank 1.

[0028] The barrel shaking mechanism 2 includes a support base 21, a first drive motor 22 is fixedly connected to the top of the support base 21, an acute-angle bracket 23 is fixedly connected to the rotating shaft of the first drive motor 22, side support frames 24 are symmetrically fixedly connected to the top of the support base 21 on both sides of the first drive motor 22, a rotating ring 25 is rotatably connected to the inner side of the two sets of side support frames 24, a columnar support platform 26 is provided inside the rotating ring 25, a set of longitudinal rotating shafts 27 that pass through the columnar support platform 26 is fixedly connected to the inner side of the columnar support platform 26, the two ends of the longitudinal rotating shafts 27 are rotatably connected to the inner side of the rotating ring 25, and the top of the columnar support platform 26 is fixedly connected to the bottom of the dispersion barrel 1.

[0029] When the first drive motor 22 starts, its rotating shaft drives the acute angle bracket 23 to rotate. Due to the specific angle design of the acute angle bracket 23, the columnar support platform 26 is connected to the rotating ring 25 through the longitudinal rotating shaft 27, thus achieving oscillation. At the same time, under the symmetrical support of the two sets of side support frames 24, the rotating ring 25 converts the rotational motion into the uniform cyclic shaking of the columnar support platform 26 and the dispersion tank 1, promoting the mixing and dispersion of the material in the dispersion tank 1.

[0030] The emulsification and dispersion mechanism 3 includes a barrel cover 31. A sealing ring 32 adapted to the dispersion barrel 1 is fixedly connected to the lower part of the barrel cover 31. A second drive motor 33 is fixedly connected to the upper part of the barrel cover 31. A first gear 34 is fixedly connected to the lower part of the barrel cover 31. A three-way support plate 35 is fixedly connected to the movable end of the second drive motor 33 through the barrel cover 31 and the first gear 34. Three sets of second gears 36 are rotatably connected in a ring at equal intervals above the three-way support plate 35. Three sets of third gears 37 and three sets of fourth gears 38 are rotatably connected in a ring at equal intervals below the three-way support plate 35. A stirring shaft 39 is fixedly connected to the lower part of each set of fourth gears 38. The rotation shafts of the second gears 36 and the third gears 37 are fixedly connected to each other through the three-way support plate 35. Each set of third gears 37 and the corresponding fourth gears 38 mesh with each other. Each set of second gears 36 meshes with the outer side of the first gear 34.

[0031] When the second drive motor 33 starts, it drives the three-way support plate 35 to rotate, which in turn drives the three sets of second gears 36 to revolve around the fixed first gear 34. Since each set of second gears 36 meshes with the first gear 34, the second gears 36 rotate on their own axis during the revolution. The rotating shaft of the second gear 36 drives the third gear 37 to rotate synchronously. The third gear 37 then drives the meshing fourth gear 38 to rotate in the opposite direction. Finally, the fourth gear 38 drives the three sets of stirring shafts 39 to perform planetary compound motion, forming a multi-directional stirring flow field, thereby realizing the three-dimensional mixing and shear emulsification of the material in the dispersion tank 1.

[0032] The working principle of this utility model is as follows: First, the pesticide suspension material to be processed is injected into the dispersion tank 1. The first drive motor 22 of the tank shaking mechanism 2 is started, and its rotating shaft drives the acute angle bracket 23 to rotate. Due to the specific angle design of the acute angle bracket 23, the columnar support platform 26 achieves eccentric swing inside the rotating ring 25 through the longitudinal rotating shaft 27. At the same time, the rotating ring 25 rotates under the support and constraint of the two sets of symmetrically arranged side support frames 24, which converts the rotational motion of the first drive motor 22 into uniform cyclic shaking of the columnar support platform 26 and the dispersion tank 1 fixedly connected above it. This shaking promotes the initial mixing of the material in the tank, effectively prevents particle sedimentation, and creates conditions for subsequent fine dispersion. Meanwhile, the tank cover 31 of the emulsification dispersion mechanism 3 is sealed tightly with a sealing ring 32 to seal the dispersion tank 1.

[0033] The second drive motor 33 of the emulsifying and dispersing mechanism 3 is activated. The movable end of the second drive motor 33 drives the three-way support plate 35 to rotate. Since the first gear 34 is fixedly installed below the barrel cover 31, the rotation of the three-way support plate 35 causes the three sets of second gears 36, which are equidistantly mounted in a ring on it, to revolve around the first gear 34. During the revolution, each set of second gears 36 meshes with the fixed first gear 34, thereby forcing the second gears 36 to rotate on their own axis while revolving. The rotation of the second gears 36 is transmitted through the rotating shaft that passes through the three-way support plate 35 and is fixedly connected to each other. The transmission is transmitted to the lower third gear 37, which drives the third gear 37 to rotate synchronously. Each set of third gears 37 then drives the fourth gear 38 corresponding to its meshing position to rotate in the opposite direction. The stirring shaft 39 fixed below the fourth gear 38 is thus driven. Each stirring shaft 39 is performing a planetary compound motion of revolving around the central axis of the three-way support plate 35 and rotating in the opposite direction around its own axis. The material in the dispersion tank 1 is subjected to the cyclic shaking effect brought by the tank shaking mechanism 2 on the one hand, and the strong shearing, convection and turbulence effect generated by the planetary compound motion of the three stirring shafts 39 on the other hand.

[0034] The synergistic effect of the three-dimensional flow field formed by the shaking of the barrel and the multi-axis stirring ultimately achieves efficient shear emulsification and homogeneous dispersion of pesticide suspensions, significantly improving their suspension stability and uniformity until the process requirements are met and the processing is completed.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
