[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-6 As shown, a pesticide production reaction apparatus includes: a reaction chamber 1, with a fixed box 2 fixedly installed on the top of the reaction chamber 1; a stirring assembly disposed inside the reaction chamber 1, the stirring assembly including: a stirring rod 204, a concentric bearing 4, a bushing 402 and a stirring rod 405; and a filter assembly disposed on the top of the reaction chamber 1, the filter assembly including: an exhaust pipe 5, a filter box 501, a rotating fan 502 and a filter bottle 504.

[0024] The stirring assembly allows the stirring rod 204 and the agitator 405 to rotate coaxially in opposite directions, breaking down internal or local concentration differences during pesticide production reactions. This facilitates liquid exchange between different regions, accelerates the reaction of reactants, and increases the reaction rate. The filtration assembly allows the gas produced during the reaction to be discharged into the filtration box 501, where harmful substances or irritating molecules are absorbed. The filtered gas is then discharged through the exhaust pipe 505. This centralized collection and filtration of the gas prevents irritating gases from being discharged along with the pesticides.

[0025] The reaction chamber 1 is equipped with a support bracket 101 at its bottom, a feeding pipe 102 at one side, a discharge solenoid valve 103 at its outer side, a discharge pipe 104 at one side of the discharge solenoid valve 103, a motor 201 at its top, a rotating shaft 202 at its bottom, the rotating shaft 202 passing through the fixed box 2 and extending into the interior of the reaction chamber 1, a drive gear 203 at its top outer side, and multiple stirring rods 204 at their outer surface. A fixed seat a3 is fixedly installed at the top inside the fixed box 2, a rotating shaft a301 is rotatably connected to the bottom of the fixed seat a3, a transmission gear a302 is fixedly installed at the outer side of the rotating shaft a301, and a fixed seat is fixedly installed at the top inside the fixed box 2. b303, a rotating shaft b304 is rotatably connected to the bottom of the fixed base b303. A transmission gear b305 and a transmission gear c306 are fixedly installed on the outside of the rotating shaft b304. The driving gear 203 meshes with the transmission gear a302, and the transmission gear a302 meshes with the transmission gear b305. A concentric bearing 4 is fixedly connected to the outside of the rotating shaft 202. A driven gear 401 that meshes with the transmission gear c306 is fixedly connected to the outside of the concentric bearing 4. A bushing 402 is fixedly installed at the bottom of the driven gear 401. A slot 403 is opened inside the bushing 402. The rotating shaft 202 passes through the slot 403. A bearing 404 is fixedly connected to the bottom of the bushing 402. The rotating shaft 202 is rotatably connected to the bearing 404. Multiple agitator rods 405 are fixedly installed on the outside of the bushing 402.

[0026] During stirring, motor 201 drives rotating shaft 202 to rotate clockwise. Rotating shaft 202 drives stirring rod 204 and drive gear 203 to rotate clockwise. Since drive gear 203 and transmission gear a302 mesh, drive gear 203 drives transmission gear a302 to rotate counterclockwise. Since transmission gear a302 and transmission gear b305 mesh, transmission gear a302 drives transmission gear b305 to rotate clockwise. Because transmission gear b305 and transmission gear c306 are fixed together on rotating shaft b304, transmission gear b305 drives rotating shaft b304 and transmission gear c306 to rotate clockwise. Meanwhile, driven gear 401 and transmission gear c306... Gears C306 mesh with each other, thus driving the driven gear 401 to rotate counterclockwise. The counterclockwise rotation of the driven gear 401 drives the bushing 402 to rotate counterclockwise, which in turn drives the stirring rod 405 to rotate counterclockwise. Through the setting of the concentric bearing 4, the rotating shaft 202 and the bushing 402 can rotate in opposite directions on the same axis, thus causing the stirring rod 204 and the stirring rod 405 to rotate in opposite directions on the same axis. The stirring rod 204 rotates clockwise and the stirring rod 405 rotates counterclockwise. The relative movement between the two rods generates shear force, increases the contact area between the liquids, accelerates the pesticide production reaction, and increases the pesticide reaction rate.

[0027] Among them, an exhaust pipe 5 is fixedly connected to one side of the reaction chamber 1, a filter box 501 is fixedly installed on the top of the reaction chamber 1, the filter box 501 is connected to one end of the exhaust pipe 5, a rotating fan 502 is fixedly installed inside the filter box 501, a gas collecting hood 503 is fixedly installed on one side of the rotating fan 502, a flexible hose is fixedly connected to one end of the gas collecting hood 503, a filter bottle 504 is set inside the filter box 501, the flexible hose is connected to the filter bottle 504, and an exhaust pipe 505 is fixedly connected to the top of the filter bottle 504.

[0028] Gas is generated during the pesticide reaction. The rotating fan 502 draws gas from the inside of the reaction chamber 1 through the gas outlet pipe 5, causing all the gas to flow to the gas outlet pipe 5. The gas passes through the gas collection hood 503 and the hose and flows into the filter bottle 504. The filter bottle 504 is filled with the corresponding impurity removal solution. For example, when producing pesticides such as dichlorvos and parathion, acidic gases such as hydrogen chloride and hydrogen sulfide are generated. At this time, adding sodium hydroxide solution to the filter bottle 504 can effectively absorb the acidic gases and absorb and filter harmful substances or irritating molecules in the gas. The filtered gas is discharged through the exhaust pipe 505, reducing the need for subsequent gas treatment.

[0029] Working principle:

[0030] During stirring, motor 201 drives rotating shaft 202 to rotate clockwise. Rotating shaft 202 drives stirring rod 204 and drive gear 203 to rotate clockwise. Since drive gear 203 and transmission gear a302 mesh, drive gear 203 drives transmission gear a302 to rotate counterclockwise. Since transmission gear a302 and transmission gear b305 mesh, transmission gear a302 drives transmission gear b305 to rotate clockwise. C306 is fixed together with the rotating shaft B304. Because the transmission gear B305 drives the rotating shaft B304 and the transmission gear C306 to rotate clockwise, and the driven gear 401 meshes with the transmission gear C306, the transmission gear C306 drives the driven gear 401 to rotate counterclockwise. The counterclockwise rotation of the driven gear 401 drives the bushing 402 to rotate counterclockwise, thereby causing the bushing 402 to drive the stirring rod 405 to rotate counterclockwise. Through the setting of the concentric bearing 4, the rotating shaft 20 can be rotated. 2 and bushing 402 rotate in opposite directions on the same axis, causing stirring rod 204 and agitator 405 to rotate in opposite directions on the same axis. Stirring rod 204 rotates clockwise and agitator 405 rotates counterclockwise. The relative motion between the two rods generates shear force, increasing the contact area between the liquids, accelerating the pesticide production reaction, and increasing the pesticide reaction rate. Gas is generated during the pesticide reaction. Rotating fan 502 draws gas from the inside of reaction chamber 1 through gas outlet pipe 5, causing the gas to flow to gas outlet pipe 5. The gas flows through gas collection hood 503 and hose into filter bottle 504. A corresponding impurity removal solution is added to filter bottle 504. For example, when producing pesticides such as dichlorvos and parathion, acidic gases such as hydrogen chloride and hydrogen sulfide are generated. At this time, adding sodium hydroxide solution to filter bottle 504 can effectively absorb acidic gases and absorb and filter harmful substances or irritating molecules in the gas. The filtered gas is discharged through exhaust pipe 505, reducing the need for subsequent gas treatment.
