[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous extraction device for plant-derived pesticides, comprising an outer tank, an inner tank, and a left tank cover. A rotating shaft is rotatably connected to one side of the left tank cover, and a spiral mechanism is fixedly connected to the surface of the rotating shaft. A cleaning mechanism is provided at the top of the inner tank, and a temperature control mechanism is provided on the opposite side of the outer tank and the inner tank. The spiral mechanism includes multiple sets of positive spiral blades fixedly connected to the surface of the rotating shaft, and multiple sets of negative spiral blades fixedly connected to the surface of the rotating shaft on one side of the multiple sets of positive spiral blades. The cleaning mechanism includes multiple sets of rotating nozzles located at the top of the inner tank, with a spray pipe penetrating one side of each set of rotating nozzles, and a high-pressure water pump penetrating one side of each spray pipe. The temperature control mechanism includes a sandwich cavity located on the opposite side of the outer tank and the inner tank, with an inlet pipe penetrating one side of the bottom of the outer tank and an outlet pipe penetrating one side of the top of the outer tank.

[0006] As a further embodiment of this utility model, the positive spiral blades and the negative spiral blades are alternately distributed, and the pitch of the positive spiral blades is larger than that of the negative spiral blades. By setting the positive and negative spiral blades, the material residence time is extended.

[0007] As a further embodiment of this utility model, multiple sets of rotating nozzles are evenly distributed at the top of the inner tank, and the spray pipe is connected through the top of the outer tank and the inner tank on one side. The rotating nozzles serve to clean the inside of the inner tank.

[0008] As a further embodiment of this utility model, a servo motor is fixedly connected to one side of the rotating shaft, and a support frame is threadedly connected to the bottom of the servo motor. The support frame is threadedly connected to the left side of the left can lid, and the support frame provides support.

[0009] As a further embodiment of this utility model, a feed pipe is connected through the top left side of the inner tank, and a discharge pipe is connected through the bottom right side of the inner tank. The feed pipe and the discharge pipe serve to feed and discharge materials.

[0010] As a further embodiment of this utility model, a solvent pipe is connected through the top right side of the inner tank, a valve is provided on the surface of the discharge pipe, and a support leg is provided at the bottom of the outer tank.

The right tank cover serves to seal the tank.

[0012] This invention provides a continuous extraction device for plant-derived pesticides and insecticides, which has the following beneficial effects: This continuous extraction device for plant-derived pesticides utilizes a rotating shaft, spiral mechanism, and temperature control system. Plant materials enter the inner tank through the feed pipe. A servo motor drives the rotating shaft to rotate, causing the positive spiral blades to push the material to the right. Simultaneously, the negative spiral blades generate reverse resistance, extending the material's residence time and creating a strong mixing and shearing effect, promoting the dissolution of active ingredients. An external constant-temperature medium is circulated through the jacketed cavity, and the temperature is regulated through the inlet and outlet pipes to maintain the inner tank at the optimal extraction temperature, accelerating the penetration of the solvent into plant cells. The extracted mixture is discharged through the outlet pipe, and the discharge speed is controlled by a valve, achieving continuous production. The strong mixing and shearing effect created by the synergistic action of the positive and negative spiral blades driven by the rotating shaft, combined with precise temperature control by the constant-temperature jacket, achieves highly efficient continuous extraction of plant active ingredients, avoiding the problems of low efficiency and component degradation caused by uneven temperature control in traditional intermittent extraction methods.

[0013] This continuous extraction device for plant-derived pesticides utilizes an inner tank and cleaning mechanism. When cleaning is required, a high-pressure water pump delivers cleaning solution through a spray pipe to rotating nozzles evenly distributed at the top of the inner tank. These nozzles automatically rotate under pressure, forming a comprehensive high-pressure water curtain. The cleaning solution sprays in a fan-shaped pattern, covering the entire inner wall of the tank and effectively flushing away residual materials adhering to the tank wall and spiral mechanism. Simultaneously, a servo motor drives the rotating shaft and spiral mechanism to rotate slowly, causing the forward and reverse spiral blades to continuously change position during the cleaning process, ensuring that all surfaces are thoroughly rinsed. The waste liquid after cleaning is discharged through the discharge pipe, completing the entire cleaning process. This achieves automated cleaning, avoiding batch-to-batch contamination problems caused by pesticide residues and the risks of dead corner residues and cross-contamination inherent in traditional manual cleaning. It significantly improves the hygiene standards and efficiency of the equipment. Attached Figure Description

The cleaning mechanism 6 includes multiple sets of rotating nozzles 601 set at the top of the inner tank 2. A spray pipe 602 is connected through one side of the multiple sets of rotating nozzles 601. A high-pressure water pump 603 is connected through one side of the spray pipe 602.

An inlet pipe 702 is connected through one side of the bottom end of the outer tank 1. An outlet pipe 703 is connected through one side of the top end of the outer tank 1. The positive spiral blade 501 and the negative spiral blade 502 are alternately distributed. The pitch of the positive spiral blade 501 is larger than that of the negative spiral blade 502. By setting the positive spiral blade 501 and the negative spiral blade 502, the residence time of the material is extended. Multiple sets of rotating nozzles 601 are evenly distributed at the top of the inner tank 2, and the spray pipe 602 is connected through the top of the outer tank 1 and the inner tank 2 on one side. The rotating nozzles 601 are used to clean the inside of the inner tank 2. A servo motor 8 is fixedly connected to one side of the rotating shaft 4. A support frame 9 is threadedly connected to the bottom of the servo motor 8. The support frame 9 is threadedly connected to the left side of the left can cover 3. The support frame 9 provides support. A feed pipe 10 is connected through the top left side of the inner tank 2, and a discharge pipe 11 is connected through the bottom right side of the inner tank 2. The feed pipe 10 and the discharge pipe 11 serve to feed and discharge materials. A solvent pipe 12 is connected through the top right side of the inner tank 2.

At the same time, the anti-spiral blade 502 generates reverse resistance, prolongs the material residence time, and forms a strong mixing and shearing effect to promote the dissolution of effective components. The jacket cavity 701 is circulated with an external constant temperature medium. The temperature is circulated and regulated through the liquid inlet pipe 702 and the liquid outlet pipe 703 to keep the inner tank 2 at the optimal extraction temperature, which accelerates the penetration of the solvent into the plant cells. The extracted mixture is discharged through the discharge pipe 11. The valve 13 controls the discharge speed to realize continuous production. The second step: When cleaning is required, the high-pressure water pump 603 delivers the cleaning solution through the spray pipe 602 to the rotating nozzles 601 evenly distributed at the top of the inner tank 2. These rotating nozzles 601 rotate automatically under pressure, forming an all-round high-pressure water curtain. The cleaning solution covers the entire inner wall of the inner tank 2 in a fan-shaped spray pattern, effectively washing away residual materials adhering to the tank wall and the spiral mechanism 5. At the same time, the servo motor 8 drives the rotating shaft 4 and the spiral mechanism 5 to rotate slowly, so that the positive spiral blade 501 and the negative spiral blade 502 continuously change positions during the cleaning process, ensuring that all surfaces can be thoroughly rinsed. The waste liquid after cleaning is discharged through the discharge pipe 11, completing the entire cleaning process.
