Description

Technical Field

[0001] This utility model relates to the field of pesticide formulation processing technology, and in particular to a homogenization and emulsification device for pesticide products. Background Technology

[0002] With increasing environmental protection requirements and the development of agricultural technology, environmentally friendly pesticide formulations such as water-based pesticides are becoming increasingly popular. Water-based pesticides have advantages such as good efficacy, low environmental pollution, and low toxicity to humans and animals. However, the preparation of these pesticides requires dispersing or dissolving the pesticide active ingredient in water to form emulsions or suspensions. This places higher demands on homogenizing emulsification equipment, which needs to be able to fully homogenize and emulsify the materials to achieve a good dispersion state and ensure efficacy. Traditional homogenizing emulsification equipment suffers from problems such as low linear speed, low shear force, and long mixing time, resulting in low production efficiency. Furthermore, the prepared pesticide products may have quality problems such as uneven particle size and easy stratification and sedimentation, affecting the pesticide's effectiveness and storage stability.

[0003] In existing technologies, homogenization and emulsification devices for pesticide products achieve shearing and agitation effects solely through internal high-speed rotating stirring rods and plates. However, due to the limited number of stirring rods, this approach results in low shearing efficiency, leading to lower rotation and turbulence intensity of the liquid. Consequently, the subsequent dispersion and emulsification effects decrease, prolonging the processing cycle of agitation and emulsification. Furthermore, existing solutions only control the homogenization and emulsification effect by controlling the rotation speed. To achieve a high emulsification effect, the solution must remain inside the emulsification tank for an extended period, making it impossible to achieve efficient emulsification quality control or continuous automatic feeding and discharging processes. The existing patent (publication number: CN221832098U) discloses a homogenizing emulsification device for pesticide products. This device uses an internal agitation and shearing component to provide agitation and shearing effects on the pesticide product solution. When the pesticide product solution flows through the connecting holes, the high-speed rotation of the top shearing mesh provides a high-speed shearing process to the solution, thereby improving emulsification efficiency and shortening the overall processing cycle. The regulating component can control the flow rate of the pesticide product solution discharged downwards from any connecting hole, thus controlling the high-speed shearing effect on each layer of pesticide product solution. This allows for precise control of the emulsification processing time and the final emulsification quality without changing the rotation speed of the drive mechanism.

[0004] To address the aforementioned issues, existing patents offer solutions. However, current homogenizing emulsification devices for pesticide products typically lack a structure that combines multi-stage fixed-rotation shearing with dynamic circulation filtration. This makes it difficult to simultaneously achieve efficient shearing dispersion and real-time impurity removal, resulting in uneven particle size distribution and excessive impurity residue, which affects emulsification efficiency and product purity stability. Furthermore, the lack of a structure that combines gradient temperature control with directional flow guidance makes it difficult to precisely control the emulsion solidification and shaping process, leading to easy emulsion stratification and incomplete solidification, which affects storage stability and the longevity of the pesticide effect.

[0005] Therefore, a homogenization and emulsification device for pesticide products is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a homogenizing emulsification device for pesticide products. This device addresses the common problem that existing homogenizing emulsification devices for pesticide products often lack a structure that combines multi-stage fixed-rotation shearing with dynamic circulation filtration. This makes it difficult to simultaneously achieve efficient shearing dispersion and real-time impurity removal, resulting in uneven particle size distribution and excessive impurity residue, which affects emulsification efficiency and product purity stability. Furthermore, the lack of a structure that combines gradient temperature control and directional flow guidance makes it difficult to precisely control the solidification and shaping process of the emulsion, leading to easy stratification and incomplete solidification of the emulsion, which affects storage stability and the durability of the pesticide's efficacy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a homogenizing emulsification device for pesticide products, comprising a base, an emulsification tank fixedly connected to the top of the base, a shearing circulation assembly disposed at the top of the emulsification tank, and a temperature-controlled curing assembly disposed at the bottom of the emulsification tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application achieves the effect of fully homogenized emulsification of pesticide materials, uniform particle size distribution, and cleanliness free of impurities through the shearing circulation component, thereby improving emulsification efficiency and product purity stability. Compared with the situation in traditional homogenizing emulsification devices where insufficient shearing force leads to uneven material dispersion and impurity residue affecting efficacy, this component can realize the integrated function of multi-stage fixed-rotation shearing and dynamic circulation filtration, solving the problems of low emulsification efficiency due to insufficient shearing, product safety affected by impurity residue, and uneven concentration caused by material sedimentation in traditional methods. 2. This application achieves stable shaping of pesticide emulsions and strong bonding between active ingredients and solvents through a temperature-controlled curing component, thereby improving product storage stability and efficacy durability. Compared with traditional homogenizing emulsification devices, which lack temperature control and result in easy emulsion stratification and incomplete curing, this component can achieve gradient temperature control and directional flow synergistic processing, solving problems such as poor emulsification effect due to temperature runaway, stratification and precipitation during storage due to insufficient curing, and uneven local processing due to disordered material flow in traditional methods.

[0017] 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.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: A homogenizing emulsification device for pesticide products includes a base 1, an emulsification tank 2 fixedly connected to the top of the base 1, a shearing circulation assembly 4 disposed on the top of the emulsification tank 2, and a temperature-controlled curing assembly 5 disposed at the bottom of the emulsification tank 2. The shearing circulation assembly 4 includes a drive motor 401 fixedly connected to the top of the emulsification tank 2, a transmission main shaft 402 fixedly connected to the output end of the drive motor 401, a first fixed-rotation shear 403 fixedly connected to the bottom of the transmission main shaft 402, a filter chamber 404 fixedly connected to the rear side of the base 1, a composite filter plate 405 disposed inside the filter chamber 404, a circulation pump 406 connected to the top of the filter chamber 404, a return pipe 407 connected to the side of the circulation pump 406 away from the filter chamber 404, and the return pipe 407 connected to the emulsification tank 2.

[0019] In this embodiment: by starting the drive motor 401, its output end drives the transmission main shaft 402 to rotate at high speed in the vertical direction. The first fixed-rotation shear 403 at the bottom of the transmission main shaft 402 rotates synchronously with it. At this time, the material added through the feed pipe 8 enters the upper part of the emulsification tank 2. The first fixed-rotation shear 403 and the matching stator form a high-speed relative motion, which shears, impacts and grinds the material, initially dispersing the blocky raw material into an emulsion. Part of the emulsion flows into the filter chamber 404 on the back side of the base 1 through the branch pipe on the side of the emulsification tank 2. After multi-layer filtration by the internal composite filter plate 405, the upper coarse filter screen intercepts large particles that are not fully dispersed, and the lower activated carbon layer adsorbs small impurities and odors. The purified material gathers at the bottom of the filter chamber 404. Subsequently, the circulation pump 406 at the top of the filter chamber 404 starts, generating negative pressure to transport the clean material back to the top of the emulsification tank 2 through the return pipe 407, mixes with the newly added material, forms a dynamic circulation, prevents material sedimentation and continuously purifies.

[0020] Specifically, such as Figure 4 As shown, the temperature-controlled curing component 5 includes a heat-conducting seat 501 fixedly connected to the bottom of the emulsification tank 2. A constant temperature chamber 502 is fixedly connected to the left side of the heat-conducting seat 501, and a heating rod 503 is provided inside the constant temperature chamber 502.

[0021] Specifically, such as Figure 4 As shown, a cooling cavity 504 is fixedly connected to the right side of the heat conduction seat 501, and a cooling coil 505 is provided inside the cooling cavity 504.

[0022] Specifically, such as Figure 4 As shown, an intercavity guide connection seat 506 is fixedly connected inside the emulsifying tank 2. A second fixed-rotation shear 507 is provided at the bottom of the intercavity guide connection seat 506. The second fixed-rotation shear 507 is fixedly connected to the transmission main shaft 402 and is located inside the heat conduction seat 501.

[0023] In this embodiment: when the material enters the area of ​​the second fixed-rotation shear 507, the heat-conducting seat 501 at the bottom of the emulsification tank 2 begins to function. It fits tightly against the outer wall of the emulsification tank 2, evenly transferring heat into the tank. The heating rod 503 in the left-side constant-temperature chamber 502 is energized and generates heat. This heat is introduced into the emulsification tank 2 through the heat-conducting seat 501, maintaining the material temperature within a suitable emulsification range. This temperature is preset by the control host 3 according to the pesticide formulation, reducing material viscosity and enhancing the shearing effect. Simultaneously, the second fixed-rotation shear 507, while shearing at high speed, utilizes the heat transferred by the heat-conducting seat 501... To promote the fusion of the active ingredient and water, once the material reaches the preset emulsification effect, the control host 3 switches to the cooling mode. Coolant is introduced into the cooling coil 505 inside the right cooling chamber 504, and the heat is absorbed from the emulsification tank 2 through the heat conduction seat 501, causing the material temperature to gradually decrease. At this time, the second fixed-rotor shear 507 rotates at a low speed to ensure that the material is heated evenly during the cooling process, avoiding local temperature differences that could cause the emulsion to separate. After cooling, the movement of emulsion molecules slows down, and the active ingredient and solvent are more firmly combined, ultimately achieving stable shaping and ensuring stability during storage.

[0024] Specifically, such as Figure 2 , Figure 5 As shown, the bottom of the emulsification tank 2 is connected to a discharge pipe 6, and a control valve 7 is installed on the outside of the discharge pipe 6.

[0025] Specifically, such as Figure 2 , Figure 5 As shown, the top of the emulsification tank 2 is connected to the feed pipe 8, and the top of the feed pipe 8 is fitted with a sealing cap 9.

[0026] In this embodiment: By setting up a feed pipe 6 and a control valve 7, after the pesticide emulsion has been processed by the shearing circulation component 4 and the temperature-controlled curing component 5 to achieve the preset homogenized emulsification effect, the operator can operate the control valve 7 on the outside of the feed pipe 6. At this time, the control valve 7 adjusts the opening and closing degree of the internal channel by rotating the valve stem to control the speed at which the emulsion flows out of the feed pipe 6. By setting up an inlet pipe 8 and a sealing cap 9, before using the device, the pesticide raw material, water and various adjuvants to be processed need to be added through the inlet pipe 8 at the top of the emulsification tank 2. During operation, first pull up the sealing cap 9 at the top of the inlet pipe 8 to make it detach from the pipe port and expose the inlet. Then, slowly inject the pre-prepared material into the emulsification tank 2 through the inlet pipe 8. After the material is added, align the sealing cap 9 with the snap-fit ​​structure at the top of the inlet pipe 8 and gently press it to make the cap fit tightly with the pipe to complete the seal.

[0027] Specifically, such as Figure 1 As shown, a control host 3 is installed on the top of the base 1.

[0028] Specifically, such as Figure 1As shown, a support leg 10 is fixedly connected to the bottom of the base 1, and a rubber foot pad 11 is fixedly connected to the bottom of the support leg 10.

[0029] In this embodiment: By setting up a control host 3, before the equipment is started, the operator needs to set parameters on the control host 3. Through the host's operation interface, the required shearing speed, circulating pump 406 power, constant temperature chamber 502 heating temperature, cooling time, and other parameters are input. The built-in program of the control host 3 will convert these parameters into electrical signals and transmit them to the drive motor 401, circulating pump 406, heating rod 503, cooling coil 505, and other actuators. During operation, the control host 3 receives data from various sensors in real time. If the temperature deviation in the emulsification tank 2 is detected, the control host 3 will take action. The set value will automatically adjust the power of the heating rod 503 or the coolant flow of the cooling coil 505. By setting the support legs 10 and rubber feet 11, when the device is installed or placed, the support legs 10 at the bottom of the base 1 will support the entire device on the ground. The height of the support legs 10 is designed so that components such as the emulsifying tank 2 and the filter chamber 404 are at an easy operating height. When the device is running, the vibration generated by components such as the drive motor 401 and the transmission shaft 402 will be transmitted to the rubber feet 11 through the support legs 10. The feet absorb part of the vibration energy through their own deformation, reducing the overall shaking of the device.

[0030] Working Principle: When using this homogenizing emulsification device for pesticide products, first open the sealing cap 9 on the feed pipe 8 at the top of the emulsification tank 2. Add the pesticide raw material, water, and other adjuvants to the emulsification tank 2 through the feed pipe 8. After adding, tighten the sealing cap 9 to prevent external impurities from entering the tank and contaminating the material. This also prevents material from overflowing due to splashing during emulsification. Start the control host 3 on the top of the base 1, and set the shearing speed, circulation frequency, heating temperature, and cooling parameters. The control host 3 transmits instructions to each actuator, and the entire device begins operation. The drive motor 401 at the top of the emulsification tank 2 starts first, and its output drives the transmission shaft 402 to rotate at high speed. The transmission shaft 402 penetrates the interior of the emulsification tank 2. The bottom is connected in sequence to the first fixed-rotation shear 403 and the second fixed-rotation shear 507. With the rotation of the drive shaft 402, in the upper part of the emulsifying tank 2, the first fixed-rotation shear 403 rotates at high speed under the drive of the drive shaft 402. It cooperates with the surrounding stator structure, generating strong shearing, impact, and grinding action on the material just entering the emulsifying tank 2 through high-speed relative motion. This initially disperses the originally lumpy or large-particle pesticide raw materials, causing the material to begin forming a preliminary emulsion. At this time, the material in the emulsifying tank 2 is introduced into the filter chamber 404 through branch pipes. Its composite filter plate 405 consists of a multi-layer structure. The upper layer is a coarse filter screen to intercept large particulate impurities, and the lower layer is an activated carbon filter layer to adsorb small impurities and odors. When the material passes through the composite filter plate 405, the... Impurities are effectively trapped, and the purified material enters the bottom of the filter chamber 404. Subsequently, the circulation pump 406 at the top of the filter chamber 404 starts, generating negative pressure to transport the filtered clean material back to the top of the emulsifying tank 2 through the return pipe 407, where it mixes with newly added or currently being processed material, forming a dynamic circulation. This circulation process not only prevents local sedimentation of material in the tank, ensuring overall uniformity, but also continuously removes impurities from the material, improving product purity. After being processed by the first fixed-rotor shear 403, the material flows downward under gravity, reaching the intercavity guide connection seat 506 inside the emulsifying tank 2. This connection seat guides the material to flow precisely to the second fixed-rotor shear 507 located below it, while its sealing structure at the edge effectively prevents material from flowing out. After initial processing, the material directly penetrates downwards, ensuring that all materials undergo further processing by the second fixed-rotor shear 507. The second fixed-rotor shear 507, also driven by the transmission spindle 402, rotates at high speed. Its shearing tooth density is higher than that of the first fixed-rotor shear 403, and when combined with the corresponding stator, it generates a finer shearing force, further crushing and emulsifying the pre-processed material. This results in smaller particle sizes and more uniform particle distribution, meeting the fine requirements of pesticide emulsions. At this point, the temperature-controlled curing component 5 at the bottom of the emulsification tank 2 begins to function. The heat-conducting seat 501 at the bottom of the emulsification tank 2 is tightly fitted to the outer wall of the emulsification tank 2. The heating rod 503 inside the constant-temperature chamber 502 connected to its left side is energized and generates heat. The heat is rapidly transferred to the interior of the emulsification tank 2 through the heat-conducting seat 501.Maintaining the material inside the tank at a suitable emulsification temperature reduces viscosity, enhances shearing effect, and promotes the fusion of the active ingredient and water. During shearing, to ensure uniformity and cleanliness, after the material has undergone the second fixed-rotation shear 507 to achieve the preset emulsification effect, if cooling and solidification are required, the control unit 3 transmits instructions to the right side of the temperature-controlled curing component 5. Cooling fluid begins to flow into the cooling coil 505 inside the cooling chamber 504, absorbing heat from the emulsification tank 2 through the heat-conducting seat 501, gradually lowering the material temperature and reducing molecular velocity. This helps stabilize the emulsion and prevents stratification during subsequent storage. During cooling, the second fixed-rotation shear 507 maintains a low rotation speed to ensure uniform cooling of the material and avoid instability issues caused by localized temperature differences. After the entire emulsification process is complete, the control valve 7 on the outside of the discharge pipe 6 at the bottom of the emulsification tank 2 is opened. The pesticide emulsion, after homogenization, emulsification, and temperature control, flows out through the discharge pipe 6 and can be directly processed for subsequent packaging or storage.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
