Description

Technical Field

[0001] This utility model belongs to the field of imidacloprid acetamiprid emulsifiable concentrate processing technology, and more specifically, it relates to an imidacloprid acetamiprid emulsifiable concentrate nano-dispersion stirring device. Background Technology

[0002] In the production of imidacloprid and acetamiprid emulsifiable concentrates, the stability, efficacy, and duration of effect of the emulsifiable concentrate formulation are crucial.

[0003] Currently, the preparation of emulsifiable concentrates (ECs) often faces problems such as uneven dispersion, excessively large particle size, and wide distribution. These issues affect the solubility, permeability, and bioactivity of the ECs, thereby reducing efficacy and shortening the duration of action. Furthermore, traditional stirring devices struggle to achieve precise control over parameters such as temperature and stirring speed during processing, resulting in poor homogeneity and stability of the EC formulation. This can also increase pesticide loss and waste, and amplify environmental risks. In addition, existing equipment falls short in combining efficient carrier and adjuvant screening technologies with refined formulation preparation techniques, failing to adequately meet the demands for improved EC performance.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a nano-dispersion and stirring device for imidacloprid acetamiprid emulsifiable concentrate, in order to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This invention provides a nano-dispersion stirring device for imidacloprid acetamiprid emulsifiable concentrate, comprising a base 1, a stirring tank 2, a stirring assembly 3, a temperature control assembly 4, a feeding assembly 5, a monitoring assembly 6, and a controller 7. The temperature control assembly 4 includes a heating and cooling unit 401 and a temperature-controlled circulating pump 402. The temperature-controlled circulating pump 402 is connected to the outlet of the heating and cooling unit 401 via a metal pipe. The temperature-controlled circulating pump 402 is used to drive the temperature-controlled medium to circulate within the temperature-controlled chamber 202, thereby achieving precise control of the material temperature within the reaction chamber 201. The stirring tank 2 is mounted on the upper surface of the base 1. The stirring tank 2 includes a double-layer jacket structure, with the inner layer of the double-layer jacket structure serving as the reaction chamber. The outer layer of the double-layer jacketed structure is the temperature control chamber 202. The temperature control circulation pump 402 is connected to the upper side of the temperature control chamber 202 through a metal pipe. The water inlet of the integrated heating and cooling machine 401 is connected to the lower side of the temperature control chamber 202 through a metal pipe. The top of the mixing tank 2 is bolted with a sealing cover 8, and a stirring assembly 3 is installed on the sealing cover 8. The bottom of the mixing tank 2 is provided with a discharge port 203. It should be noted that a control valve is provided at the discharge port 203 to control the discharge of materials. The feeding assembly 5 is composed of several feeding pipes 501. One end of the feeding pipes 501 passes through one side of the mixing tank 2 and extends into the reaction chamber 201.

[0029] The stirring assembly 3 includes a drive motor 301, a stirring shaft 302, stirring paddles 303, and a dispersing disc 304. The drive motor 301 is mounted on the upper surface of the sealing cover 8. The top of the sealing cover 8 is rotatably connected to the stirring shaft 302. The top end of the stirring shaft 302 passes through the upper surface of the sealing cover 8 and is connected to the output end of the drive motor 301. The bottom end of the stirring shaft 302 extends into the temperature control chamber 202. The dispersing disc 304 is installed at the bottom end of the stirring shaft 302. Several stirring paddles 303 are installed on the periphery of the stirring shaft 302 above the dispersing disc 304. The dispersing disc 304 has multiple small dispersing holes, which can refine and disperse the material. The multi-layer stirring paddles 303 adopt a blade design with different angles, which can enhance the mixing effect of the material.

[0030] The integrated heating and cooling unit 401 is installed on the upper surface of the base 1 near the mixing tank 2.

[0031] The temperature-controlled circulating pump 402 is installed on the upper surface of the base 1 between the mixing tank 2 and the integrated heating and cooling unit 401. When the temperature inside the mixing tank 2 is too high, the integrated heating and cooling unit 401 heats the temperature-controlled medium and delivers the medium to the temperature-controlled chamber 202 through the temperature-controlled circulating pump 402 to raise the temperature of the mixing tank 2. When the temperature inside the mixing tank 2 is too low, the integrated heating and cooling unit 401 cools the temperature-controlled medium and delivers the temperature-controlled medium to the temperature-controlled chamber 202 through the temperature-controlled circulating pump 402 to cool the mixing tank 2.

[0032] The controller 7 is installed on the upper surface of the base 1 on the side away from the integrated cooling and heating unit 401.

[0033] Among them, a guide plate 204 is installed on one side of the inner wall of the mixing tank 2 below several feed pipes 501. The raw materials enter evenly under the action of the guide plate 204 to avoid excessive local concentration.

[0034] The monitoring component 6 includes a particle size sensor 601, a temperature sensor 602, and a pressure sensor 603. The particle size sensor 601 is installed on the inner wall of one side of the mixing tank 2 and is used to monitor the particle size distribution of the material in real time. The top of the sealing cover 8 is equipped with a temperature sensor 602 and a pressure sensor 603. The temperature sensor 602 is used to monitor the temperature inside the mixing tank 2 in real time, and the pressure sensor 603 is used to monitor the pressure inside the mixing tank 2 in real time.

[0035] The feed pipe 501 is equipped with a valve 502, and one end of the feed pipe 501 is connected to a metering pump 503. Each feed pipe 501 corresponds to the feeding of raw materials such as imidacloprid, acetamiprid, emulsifier, stabilizer, and additives. Each feed pipe 501 is equipped with a metering pump 503 and a valve 502, which can accurately control the feeding amount of each raw material.

[0036] The controller 7 is electrically connected to the drive motor 301, the temperature control component 4, the feeding component 5, and the monitoring component 6. The controller 7 has a control program that can automatically adjust parameters such as stirring speed, reaction temperature, and feed amount of each raw material according to the data transmitted from the monitoring component 6, so as to realize the automated control of the entire stirring and dispersion process.

[0037] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and controller 7 of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the specific details of its power mechanism, power supply system and controller 7 can be clearly understood. The control method in the application document is automatic control through controller 7. The control circuit of controller 7 can be implemented by those skilled in the art through simple programming.

[0038] The working principle of this embodiment:

[0039] 1. Preparation stage: Check whether each part of the device is operating normally, ensure that the reaction chamber 201 of the stirring tank 2 is clean and free of impurities, and set the parameters such as the feed rate of each raw material, stirring speed, and reaction temperature through the controller 7 according to the preset emulsion formula.

[0040] 2. Feeding process: Start the feeding assembly 5, and through the metering pump 503 and valve 502 on each feeding pipe 501, the raw materials such as imidacloprid, acetamiprid, emulsifier, stabilizer, and additives are sequentially transported into the reaction chamber 201 of the mixing tank 2 according to the set amount. The raw materials enter evenly under the action of the guide plate 204 to avoid excessive local concentration.

[0041] 3. Stirring and Dispersion Process: The drive motor 301 of the stirring assembly 3 is started, and stirring begins at the set stirring speed. In the initial stage, the multi-layer stirring paddle 303 performs preliminary mixing of the materials. As stirring progresses, the nano-dispersion disk 304 begins to function, dispersing the materials at the nanoscale. Simultaneously, the temperature control assembly 4 starts working, maintaining the temperature within the reaction chamber 201 within the set range through heating or cooling. The monitoring assembly 6 monitors the particle size distribution, temperature, and pressure of the materials in real time and transmits the data to the controller 7. Based on the monitoring data, the controller 7 automatically adjusts the stirring speed and temperature to ensure uniform material dispersion.

[0042] 4. Adjustment and Optimization Process: During the stirring and dispersion process, if the particle size distribution of the material is found to be unsatisfactory, the controller 7 will automatically increase the stirring speed or extend the stirring time; if the temperature deviates from the set value, the temperature control component 4 will adjust it in a timely manner. Through such dynamic adjustments, the uniformity and stability of the emulsifiable concentrate formulation are ensured.

[0043] 5. Completion Stage: When the monitoring component 6 displays that the particle size distribution, temperature, and other parameters of the material reach the preset standards, the controller 7 sends a signal to stop the operation of the stirring component 3, the temperature control component 4, and the feeding component 5. The control valve of the discharge port 203 at the bottom of the stirring tank 2 is opened to discharge the prepared imidacloprid acetamiprid emulsifiable concentrate for collection and later use.

[0044] 6. Cleaning stage: After the material has been completely discharged, the reaction chamber 201 of the mixing tank 2 is cleaned to prepare for the next production.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
