Description

Technical Field

[0001] This utility model belongs to the field of pesticide formulation production technology, and in particular relates to an emulsification reaction device for preparing pesticide water-in-oil emulsions. Background Technology

[0002] Pesticide emulsion emulsification refers to the process of uniformly dispersing water-insoluble liquid pesticide active ingredients into water under the action of specific equipment and adjuvants to form a stable emulsion. The essence of this process is to overcome the interfacial tension between the oil phase and the water phase by external force and reduce the interfacial energy of the two phases with the help of emulsifiers, so that the oil phase is stably suspended in the water phase in the form of tiny droplets rather than stratified. Its core purpose is to convert oily active ingredients into water-based formulations, which can not only reduce the use of organic solvents and reduce environmental risks, but also improve the dispersibility and utilization rate of pesticides during application. It is a key process step in the production of environmentally friendly pesticide emulsions.

[0003] The pesticide emulsification reaction device for preparing water-in-water emulsions is a specialized piece of equipment used to achieve uniform mixing of the oil phase and the water phase of pesticides to form a stable emulsion. Its core function is to overcome the interfacial tension between the two phases through mechanical external force, and with the help of emulsifiers, disperse the oil phase into tiny droplets and stably suspend them in the water phase. Common forms of mechanical external force include shearing, grinding, and stirring. The device usually includes a power system and dispersion and mixing components, such as stators, rotors, and stirring heads. Some devices also integrate temperature control, vacuum, or circulation systems to adapt to materials of different viscosities and ensure emulsification efficiency and product stability. This type of device is the core equipment for the production of pesticide water-in-water emulsions, directly affecting the dispersibility, uniformity, and final performance of the formulation.

[0004] Currently, in the use of existing pesticide emulsion reaction devices, stirring is often relied upon to achieve emulsification of water-in-oil emulsions. However, existing stirring devices generally lack height adjustment function. This results in the stirring component being fixed in position inside the tank, making it impossible to flexibly adjust the height according to actual production needs, such as changes in material liquid level or the mixing requirements of different emulsification stages. The fixed stirring position will cause insufficient mixing of materials in some areas of the tank, making it difficult to achieve the ideal emulsification effect. This, in turn, affects the uniformity and stability of the final product, thus restricting the improvement of water-in-oil emulsion preparation efficiency.

[0005] To address the aforementioned issues, this application proposes an emulsification reaction apparatus for preparing water-in-oil emulsions of pesticides. Utility Model Content

[0006] The purpose of this invention is to provide an emulsification reaction device for preparing pesticide water-in-oil emulsions, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to an emulsification reaction device for preparing water-in-oil emulsions of pesticides, comprising a reaction vessel, a rotary motor and an electric push rod respectively disposed above the reaction vessel, a stirring frame disposed inside the reaction vessel, a rotating collar slidably connected to the outer surface of the stirring frame, the outer surface of the outer ring of the rotating collar being fixedly connected to the inner wall of the reaction vessel, the output end of the rotary motor being fixedly connected to the top end of the stirring frame, a fixing frame being fixedly connected to the upper surface of the reaction vessel, a sliding frame being slidably connected to the outer surface of the fixing frame, the left side of the sliding frame being fixedly connected to the right side of the rotary motor, a connecting plate being fixedly connected to the telescopic end of the electric push rod, the left side of the connecting plate being fixedly connected to the right side of the sliding frame, and a controller being disposed outside the reaction vessel.

[0009] Furthermore, a support frame is fixedly connected to the outer surface of the reactor, and two sets of support columns are fixedly connected to the bottom surface of the support frame.

[0010] Furthermore, a support platform is fixedly connected to the upper surface of the support frame, and the left side of the support platform is fixedly connected to the right side of the controller.

[0011] Furthermore, a sealing ring is fixedly connected to the upper surface of the inner ring of the rotating collar, and the inner wall of the sealing ring is in contact with the outer surface of the stirring frame.

[0012] Furthermore, a reinforcing frame is fixedly connected to the outer surface of the fixed frame, and the bottom surface of the reinforcing frame is fixedly connected to the upper surface of the reactor.

[0013] Furthermore, a connecting ring is fixedly connected to the bottom end of the electric push rod, and the bottom surface of the connecting ring is fixedly connected to the upper surface of the reactor.

[0014] Furthermore, a limiting plate is fixedly connected to the upper surface of the fixing frame, and a protective pad is fixedly connected to the bottom surface of the limiting plate.

[0015] This utility model has the following beneficial effects:

[0016] This invention, through the coordinated operation of an electric push rod, a sliding frame, and a fixed frame, can stably drive a rotary motor and a stirring frame connected to it to flexibly rise and fall vertically, thereby achieving precise adjustment of the stirring components at different heights inside the reactor. This design can adjust the stirring position at any time according to the dynamic changes in the liquid level of the material during the reaction process and the different requirements for mixing intensity at different emulsification stages. It effectively solves the problem of insufficient mixing and uneven emulsification effect in some parts of the tank due to the fixed stirring position in traditional emulsification reaction devices, ensuring that the material in each area of ​​the reactor can fully contact and complete the emulsification reaction.

[0017] This invention, through the reasonable setting of the rotating collar, provides stable support for the high-speed rotation of the stirring frame, avoiding the impact of shaking on the mixing effect during the stirring process. On the other hand, the tight fit between the rotating collar and the stirring frame can reduce the volatilization loss of materials inside the reactor during high temperature or stirring, while preventing impurities in the outside air from entering the reaction system. This significantly improves the sealing and operational safety of the device during overall operation, ensuring that the quality of pesticide emulsion products is not affected by external factors.

[0018] In summary, this device effectively optimizes the emulsification reaction of pesticide emulsions through its highly adjustable stirring structure design. Simultaneously, the support and sealing effect of the rotating collar ensures both stability and safety during operation. This design not only improves the preparation efficiency of pesticide emulsions but also guarantees the product's performance in key indicators such as uniformity and stability, meeting the practical needs of large-scale, high-quality production of environmentally friendly pesticide emulsions.

[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] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-6 As shown, this utility model is a pesticide preparation water-in-oil emulsion reaction device, including a reaction vessel 1. A rotary motor 6 and an electric push rod 11 are respectively arranged on the top of the reaction vessel 1. A stirring frame 9 is arranged inside the reaction vessel 1. A rotating collar 8 is slidably connected to the outer surface of the stirring frame 9. The outer surface of the outer ring of the rotating collar 8 is fixedly connected to the inner wall of the reaction vessel 1. The output end of the rotary motor 6 is fixedly connected to the top of the stirring frame 9. A fixing frame 4 is fixedly connected to the upper surface of the reaction vessel 1. A sliding frame 5 is slidably connected to the outer surface of the fixing frame 4. The left side of the sliding frame 5 is fixedly connected to the right side of the rotary motor 6. A connecting plate 10 is fixedly connected to the telescopic end of the electric push rod 11. The left side of the connecting plate 10 is fixedly connected to the right side of the sliding frame 5. A controller 16 is arranged on the outside of the reaction vessel 1.

[0032] In this embodiment, the rotary motor 6 and the electric push rod 11 adopt explosion-proof drive components, which meet the safety and explosion-proof requirements for pesticide production, ensuring stable operation of the equipment in flammable and explosive environments. At the same time, the controller 16 adopts a PLC programmable controller, which can accurately control the speed of the rotary motor 6 and the lifting stroke of the electric push rod 11 to achieve automated operation. The rotating collar 8 is divided into inner and outer rings. The inner ring slides with the stirring frame 9, and the outer ring is fixedly connected to the inner wall of the reaction vessel 1, taking into account both support stability and stirring flexibility.

[0033] The outer surface of the reactor 1 is fixedly connected to a support frame 2, and the bottom surface of the support frame 2 is fixedly connected to two sets of support columns 3. In this embodiment, the support frame 2 and the two sets of support columns 3 cooperate to provide stable support for the reactor 1, so as to prevent the reactor 1 from shifting due to equipment vibration during the stirring and emulsification process. At the same time, the installation height of the reactor 1 is raised, which makes it easier for operators to inspect and maintain the bottom of the reactor 1.

[0034] The upper surface of the support frame 2 is fixedly connected to the support platform 17. The left side of the support platform 17 is fixedly connected to the right side of the controller 16. In this embodiment, the support platform 17 provides a dedicated installation position for the controller 16, so that the controller 16 and the reactor 1 maintain a reasonable distance, avoiding the high temperature and vibration during equipment operation from affecting the operating accuracy of the controller 16, and at the same time facilitating the operator to view and operate the controller 16 at any time.

[0035] In this embodiment, a sealing ring 7 is fixedly connected to the upper surface of the inner ring of the rotating collar 8. The inner wall of the sealing ring 7 is in contact with the outer surface of the stirring frame 9. In this embodiment, the sealing ring 7 fills the gap between the rotating collar 8 and the stirring frame 9, which further enhances the sealing performance of the device, reduces the leakage of volatile materials in the reactor 1, and can also better block external dust and other impurities from entering, thus ensuring the cleanliness of the emulsification reaction environment.

[0036] The outer surface of the fixed frame 4 is fixedly connected to the reinforcing frame 13. The bottom surface of the reinforcing frame 13 is fixedly connected to the upper surface of the reactor 1. In this embodiment, the connection strength between the fixed frame 4 and the reactor 1 is reinforced by the reinforcing frame 13, so as to prevent the fixed frame 4 from tilting or breaking when it carries the rotating motor 6 and moves with the sliding frame 5, thus ensuring the stability and safety of the lifting and adjusting process of the stirring assembly.

[0037] The bottom end of the electric push rod 11 is fixedly connected to a connecting ring 12. The bottom surface of the connecting ring 12 is fixedly connected to the upper surface of the reactor 1. In this embodiment, the connecting ring 12 increases the contact area between the electric push rod 11 and the reactor 1, making the installation of the electric push rod 11 more secure and preventing it from loosening during repeated extension and retraction, thus ensuring stable transmission of driving force to the sliding frame 5 and the stirring assembly.

[0038] In this embodiment, the upper surface of the fixed frame 4 is fixedly connected to the limiting plate 14, and the bottom surface of the limiting plate 14 is fixedly connected to the protective pad 15. The limiting plate 14 restricts the upper limit position of the sliding frame 5 to prevent it from moving excessively and causing the component to collide and be damaged. The protective pad 15 can buffer the impact force when the sliding frame 5 contacts the limiting plate 14, reduce the wear and noise caused by the collision, and extend the service life of the component.

[0039] Understandably, this invention, through the cooperation of the electric push rod 11, the sliding frame 5, and the fixed frame 4, can drive the rotary motor 6 and the stirring frame 9 to flexibly lift and lower, thereby adjusting the height of the stirring components within the reactor 1 to adapt to different working conditions. This solves the problem of uneven emulsification caused by the fixed stirring position in traditional devices. At the same time, the rotating collar 8 not only provides stable support for the rotation of the stirring frame 9, but its close cooperation with the stirring frame 9 also reduces material volatilization, blocks impurities, enhances the sealing and safety of the device, and ensures product quality.

[0040] One specific application of this embodiment is as follows: During use, first verify the ratio of pesticide technical, deionized water, and emulsifier. Add the preset dosage of materials sequentially through the sealed inlet at the top of the reactor 1. Close the sealing cap to ensure the reactor is airtight. The operator starts the equipment via the controller 16 on the support platform 17. The controller 16 first instructs the rotary motor 6 to rotate, driving the rigidly connected stirring frame 9 to rotate, performing preliminary mixing of the materials to lay the foundation for efficient emulsification. After preliminary mixing, observe and confirm the liquid level. Set the stroke of the electric push rod 11 through the touch interface of the controller 16. The electric push rod 11, via the connecting plate 10, drives the sliding frame 5 to move along the guide rail of the fixed frame 4, adjusting the stirring frame 9 to the optimal position of the intermediate liquid level. Simultaneously, the reinforcing frame 13 enhances the load-bearing stability of the fixed frame 4, and the connecting ring 12 increases the electric push rod's stroke. The contact area between rod 11 and reactor 1 ensures stable transmission of driving force. During emulsification, when the liquid level drops or the stage changes, the electric push rod 11 can be adjusted in real time by controller 16. The stirring frame 9 slides along the inner ring of rotating collar 8, while the outer ring of rotating collar 8 is fixed to the reactor wall to provide stable support. The sealing ring 7 fits the stirring frame 9 to prevent leakage and impurities from entering. When the sliding frame 5 rises to its limit, the limit plate 14 limits it, and the protective pad 15 buffers the collision. When the preset emulsification time is reached, the motor and push rod are turned off in sequence by controller 16. After the stirring frame 9 stops rotating, the bottom discharge valve is opened to discharge the material. During operation, the support frame 2 and the support column 3 form a stable support system to offset vibration and prevent displacement. After the reaction is completed, the inside of reactor 1 and stirring frame 9 are cleaned to complete maintenance for the next use.
