During the preparation of pesticides, an external pressurization structure for a reaction kettle barrel type is required for physical pressurization.

[0003] A Chinese patent with the authorization announcement number CN 218485909 U discloses a pressurizable high-efficiency chemical reaction kettle, including: a base and a reaction tank, the reaction tank is fixedly arranged on the base, a first partition plate and a second partition plate are fixedly arranged in the reaction tank, and the first partition plate and the second partition plate sequentially divide the reaction tank into a pressurization cavity, a reaction cavity, and a driving cavity. The reaction tank is also provided with a pressure relief port; a feed hopper, the discharge end of which extends into the reaction tank, and a discharge pipe is correspondingly arranged for the feed hopper; a pressurization mechanism, the main body of which is arranged in the pressurization cavity; a pressure relief mechanism, fixedly arranged on the inner wall of the reaction tank and located at the pressure relief port opened by the reaction tank; a mixing mechanism, which is rotatably installed on the second partition plate. The pressurizable high-efficiency chemical reaction kettle provided by the utility model can not only pressurize the inside of the reaction kettle, but also fully mix the reactants, greatly accelerating the reaction rate. At the same time, it is easy to relieve the pressure of the reaction kettle, with simple operation and strong practicability.

[0004] During the pressurization process of the existing external pressurization structure for a reaction kettle barrel type, convenient and efficient pressurization operations cannot be carried out, resulting in poor pressurization effects. Therefore, an external pressurization structure for a reaction kettle barrel type is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problems existing in the prior art, the utility model proposes an external pressurization structure for a reaction kettle barrel type.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A barrel-type external pressurization structure of a reaction kettle according to the present utility model includes a control box.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5As shown in the figure, a barrel external pressurization structure for a reaction kettle includes a control box 1. A fixed plate 2 is installed on the control box 1, and a cover body 3 is installed on the fixed plate 2. A first storage container 4 is installed on the cover body 3 through a support frame. A first conduit 5 is installed on the first storage container 4, a first feed hopper 6 is installed on the first conduit 5, and a first valve 7 is installed on the first conduit 5. A liquid conduit 8 is installed at the bottom side of the first storage container 4. A pressure pipe 9 is installed on the cover body 3, and the pressure pipe 9 is connected to the liquid conduit 8 and the liquid conduit 8 is located inside the pressure pipe 9. The pressure pipe 9 is an irregular tubular structure. A second storage container 10 is installed on the cover body 3 through a support frame. A second conduit 11 is installed on the second storage container 10, a second feed hopper 12 is installed on the second conduit 11, and a second valve 13 is installed on the second conduit 11. A third conduit 35 is installed at the bottom side of the second storage container 10, and the third conduit 35 is connected to the cover body 3. An air inlet pipe 14 is installed on the cover body 3, and a third valve 15 is installed on the air inlet pipe 14. An air outlet pipe 16 is installed on the cover body 3, and a fourth valve 17 is installed on the air outlet pipe 16. A buffer pipe 18 is installed on the cover body 3, and a pressure gauge 19 is installed on the buffer pipe 18. A plurality of rod holes are formed on the cover body 3, and a nut 20 is rotatably installed at the position of the rod hole on the cover body 3. A motor 21 is installed on the cover body 3 through a machine base. A stirring rod 22 is installed on the output shaft of the motor 21, and stirring blades 23 are installed on the stirring rod 22. A chute 24 is formed inside the control box 1, a hydraulic cylinder 25 is installed inside the upper part of the chute 24, a hydraulic rod 26 is installed on the hydraulic cylinder 25, a slider 27 is installed on the hydraulic rod 26. A connection groove 28 is formed on the side wall of the control box 1, and a lifting frame 29 is assembled in the connection groove 28. The lifting frame 29 is fixedly connected to the slider 27. A base 30 is installed on the side wall of the control box 1, and a reaction kettle 31 is installed on the lifting frame 29. A plurality of screw rods 32 are installed on the reaction kettle 31, and a cylindrical frame 33 is installed on the inner wall of the reaction kettle 31. A plurality of baffles 34 are installed on the cylindrical frame 33; during operation, in the existing barrel external pressurization structure for a reaction kettle, during the pressurization process, convenient and efficient pressurization operations cannot be carried out, resulting in poor pressurization effects. By operating the hydraulic cylinder 25, the hydraulic rod 26 drives the slider 27 to move vertically upward, the slider 27 drives the lifting frame 29 to move vertically upward, and the lifting frame 29 drives the reaction kettle 31 to move vertically upward to contact the cover body 3. Moreover, the screw rods 32 on the reaction kettle 31 penetrate through the nuts 20 on the cover body 3, and by rotating the nuts 20 and screwing the nuts 20 onto the screw rods 32, the sealed fastening of the reaction kettle 31 and the cover body 3 is achieved through the tight connection of the nuts 20 and the screw rods 32;

[0020] After pouring the liquid into the first feed hopper 6, it flows into the first storage container 4, then through the liquid conduit 8, and finally into the interior of the reaction kettle 31 from the liquid conduit 8. During the process of flowing through the liquid conduit 8, since the pressure pipe 9 has an irregular tubular structure, the pressure pipe 9 regularly squeezes the liquid conduit 8, causing the internal diameter of the liquid conduit 8 to change. When the liquid flows through the liquid conduit 8, the pressure is increased due to the diameter change, enhancing the force between particles, thus achieving the purpose of physical extrusion;

[0021] After the liquid is poured into the interior of the reaction kettle 31, the relevant reagents are poured into the interior of the reaction kettle 31 from the second feed hopper 12. Then, through the operation of the motor 21, the stirring rod 22 is driven to rotate at high speed. The stirring rod 22 drives the stirring blades 23 to rotate at high speed, and the stirring blades 23 stir the organic compound;

[0022] During the process of stirring the organic compound, if the reaction kettle 31 is not provided with baffles 34, about one minute after the motor 21 is started, the organic compound will generate centrifugal force along with the rotation of the stirring rod 22, forming a liquid level at the center of the stirring shaft and a liquid level of the material near the inner wall of the reaction kettle 31, which is the so-called "vortex" phenomenon. The "vortex" phenomenon is a fluid mechanics phenomenon, referring to a vortex-like flow formed when a fluid rotates. The vortex will consume the kinetic energy of the water flow. By installing multiple baffles 34 in the reaction kettle 31, the "vortex" will be greatly weakened, thereby improving the efficiency of stirring and mixing. By adding multiple baffles 34 to the cylindrical frame 33, the pressure in the reaction kettle 31 during the organic stirring work is increased due to the blocking of the baffles 34, thus achieving the purpose of physical extrusion and preparing a nanoscale organic compound; this structure improves the force between particles by physically pressurizing the compound, and then adding the relevant reagents, enabling the preparation of a nanoscale organic compound. Before the two physical pressurizations: the particle size range of the organic compound is about 1000 - 10000 nanometers, and after the transformation: the particle size range of the organic compound is about 80 - 100 nanometers, greatly enhancing the chemical effect of the nanoscale pesticide and being beneficial to improving the pressurization effect.

[0023] Working principle: During the pressurization process of the existing external pressurization structure of the reaction kettle barrel, convenient and efficient pressurization operations cannot be carried out, resulting in poor pressurization effects. Through the operation of the hydraulic cylinder 25, the hydraulic rod 26 drives the slider 27 to move vertically upward. The slider 27 drives the lifting frame 29 to move vertically upward, and the lifting frame 29 drives the reaction kettle 31 to move vertically upward to contact the cover body 3. Moreover, the screw rod 32 on the reaction kettle 31 passes through the nut 20 on the cover body 3. Rotate the nut 20 and screw the nut 20 onto the screw rod 32. Through the tight connection between the nut 20 and the screw rod 32, the sealed fastening of the reaction kettle 31 and the cover body 3 is achieved; then pour the liquid into the first feed hopper 6, and then it flows into the first storage container 4, then through the liquid conduit 8, and finally pour it into the reaction kettle 31 from the liquid conduit 8. During the process of flowing through the liquid conduit 8, since the pressure pipe 9 is an irregular tubular structure, the pressure pipe 9 regularly squeezes the liquid conduit 8, causing the internal diameter of the liquid conduit 8 to change. When the liquid flows through the liquid conduit 8, the pressure is increased due to the diameter change, increasing the force between particles, thereby achieving the purpose of physical extrusion; after the liquid is poured into the reaction kettle 31, pour the relevant reagents into the reaction kettle 31 from the second feed hopper 12, and then through the operation of the motor 21, drive the stirring rod 22 to rotate at a high speed. The stirring rod 22 drives the stirring blades 23 to rotate at a high speed, and the stirring blades 23 stir the organic compound; during the process of stirring the organic compound, if the reaction kettle 31 is not provided with baffles 34, about one minute after the motor 21 is started, the organic compound will generate centrifugal force with the rotation of the stirring rod 22, forming a liquid level of the material at the center of the stirring shaft and a liquid level of the material near the inner wall of the reaction kettle 31, which is the so-called "vortex" phenomenon. The "vortex" phenomenon is a fluid mechanics phenomenon, referring to a vortex-like flow formed when the fluid rotates. The vortex will consume the kinetic energy of the water flow. By installing multiple baffles 34 in the reaction kettle 31, the "vortex" will be greatly weakened, thereby improving the stirring and mixing efficiency. By adding multiple baffles 34 on the cylindrical frame 33, the pressure in the reaction kettle 31 is increased due to the blocking of the baffles 34 during the organic stirring work, thereby achieving the purpose of physical extrusion and configuring nano-level organic compounds; this structure improves the force between particles by physically pressurizing the compound, and then adding relevant reagents, enabling the configuration of nano-level organic compounds. Before the two physical pressurizations: the particle size range of the organic compound is about 1000 - 10000 nanometers, and after the transformation: the particle size range of the organic compound is about 80 - 100 nanometers, greatly improving the chemical effect of nano-level pesticides and being beneficial to improving the pressurization effect.
