[0001] The utility model relates to the technical field of rosatidine processing, and more specifically, the utility model relates to a heat-conducting oil reaction kettle. Background Art

[0002] Rosatidine is a histamine H2 receptor antagonist, mainly used for treating diseases such as gastric ulcer, duodenal ulcer, anastomotic ulcer, gastrinoma (Zollinger-Ellison syndrome), and reflux esophagitis. In addition, it can also be used for pre-anesthetic medication to prevent acid aspiration syndrome. Using a heat-conducting oil reaction kettle in the rosatidine processing process is a common heating method. It uses heat-conducting oil as the heat medium and transfers heat to the reaction materials through heat exchange to achieve the purpose of heating and reaction. The stirring device of the heat-conducting oil reaction kettle can promote the mixing and heat transfer of the reaction materials and improve the reaction efficiency.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The embodiment of the present application discloses a heat-conducting oil reaction kettle, which includes an outer kettle 1. An inner kettle 2 is arranged inside the outer kettle 1, and a stirring assembly is installed inside the inner kettle 2; the stirring assembly includes a motor 3. A first rotating rod 4 is installed at the output end of the motor 3. A first gear 5 is fixedly connected to the outer side of the first rotating rod 4. Two second gears 6 are arranged on the outer side of the first gear 5. A support cone 7 is arranged on the outer side of the two second gears 6. Stirring rods 8 are inserted into the inner sides of the two second gears 6. The bottom ends of the two stirring rods 8 are fixedly connected with turntables 9. A plurality of stirring blades 10 are fixedly connected to the outer sides of the two turntables 9; two second rotating rods 11 are fixedly connected to the outer side of the first rotating rod 4. Scrapers 12 are fixedly connected to the bottom ends of the two second rotating rods 11. By driving the first rotating rod 4 to rotate by the motor 3, the first rotating rod 4 can drive the first gear 5 to rotate. By the rotation of the first gear 5, the second gears 6 can be meshed and driven to rotate. The two second gears 6 are both meshed and rotated on one side of the first gear 5 and the support cone 7. The support cone 7 can provide support and guiding functions for the rotation of the two second gears 6, so as to facilitate the two second gears 6 to drive the stirring rods 8 to rotate inside the inner kettle 2. The two stirring rods 8 can both drive a plurality of stirring blades 10 to rotate at the bottom end of the inner kettle 2 through the turntables 9, so as to fully mix the reaction materials in the inner kettle 2, ensure the uniform distribution of the temperature in the inner kettle 2, and avoid uneven reactions or side reactions caused by too high or too low local temperature. At the same time, the rotation of the first rotating rod 4 will drive the two second rotating rods 11 to rotate, so that the two second rotating rods 11 can both drive the two scrapers 12 to scrape on the inner wall of the inner kettle 2, which can effectively prevent the reaction materials from accumulating and remaining in lumps on the inner wall of the inner kettle 2, and ensure the uniform contact between the reactants.

[0025] Refer to Figure 2 and 3As shown, a chute 13 is provided inside the inner kettle 2, and a heat-conducting copper tube 14 is arranged between the outer kettle 1 and the inner kettle 2. The chute 13 can provide support and guidance for the two second rotating rods 11, facilitating the two second rotating rods 11 to stably drive the scraper 12 to rotate inside the inner kettle 2. The heat-conducting copper tube 14 is convenient for heat transfer between the inner kettle 2 and the outer kettle 1. Using the spiral direction of the heat-conducting copper tube 14, the heat of the heat-conducting oil inside the outer kettle 1 can be evenly transferred to the outside of the inner kettle 2, reducing the local heat difference of the reactants inside the inner kettle 2.

[0026] Refer to Figure 1 and 5 As shown, the bottom end of the heat-conducting copper tube 14 is connected to a delivery pipe 15. One side of the delivery pipe 15 is connected to a cooling box 16. The upper surface of the cooling box 16 is connected to an oil suction pipe 17. The top end of the oil suction pipe 17 is connected to an oil pump 18. The output end of the oil pump 18 is connected to an oil delivery pipe 19. Two heat-conducting plates 20 are installed inside the cooling box 16. Heat dissipation pipes 21 are arranged on one side of the two heat-conducting plates 20. Two fans 22 are installed on one side of the two heat dissipation pipes 21. The two heat-conducting plates 20 and the heat dissipation pipes 21 can effectively absorb the heat of the heat-conducting oil inside the cooling box 16, and then use the multiple fans 22 to quickly transfer the heat to the external air, which can maintain the temperature stability inside the inner kettle 2, reduce the reaction fluctuations caused by temperature changes, improve the controllability and stability of the reaction. At the same time, the oil pump 18 can transport the cooled heat-conducting oil inside the cooling box 16 to the inside of the outer kettle 1, thereby realizing the cooling cycle of the outside of the inner kettle 2, reducing the occurrence of side reactions, and improving the reaction efficiency of the reaction materials.

[0027] Refer to Figure 3 As shown, the top end of the inner kettle 2 is connected to a feed pipe 23, and the bottom end of the inner kettle 2 is connected to a discharge pipe 24. Through the feed pipe 23 and the discharge pipe 24, it is convenient for the reaction materials to quickly enter and exit the inside of the inner kettle 2, thereby ensuring the continuity and stability of the reaction materials.

[0028] The working principle of the present utility model: The present utility model designs a heat-conducting oil reaction kettle, and the specific structure is as shown in the attached Figure 1-6As shown, in this technical solution, through the mutual cooperation between various structures, when it is necessary to stir the raw materials for roxatidine reaction, first start the motor 3, and use the motor 3 to drive the first rotating rod 4 to rotate. The rotation of the first rotating rod 4 can drive the first gear 5 to rotate, so that the first gear 5 can engage and drive two second gears 6 to rotate. By using the two second gears 6 to engage and rotate with the first gear 5 and the supporting cone 7, it is convenient for the two first gears 5 to drive the stirring rod 8 to rotate, and it is convenient for the two stirring rods 8 to drive a plurality of stirring blades 10 to rotate inside the inner kettle 2 through the turntable 9, so as to evenly mix the raw materials for roxatidine reaction. At the same time, the rotation of the first rotating rod 4 can drive the two second rotating rods 11 to rotate. By using the fact that one end of each of the two second rotating rods 11 slides inside the chute 13, it is convenient for the two second rotating rods 11 to drive the scraper 12 to rotate on the inner wall of the inner kettle 2, preventing the reaction raw materials from adhering to the inner wall of the inner kettle 2. When it is necessary to cool the inside of the inner kettle 2, the heat-conducting oil inside the outer kettle 1 can be transported to the cooling box 16 through the delivery pipe 15. Then, the heat of the heat-conducting oil inside the cooling box 16 can be absorbed by the two heat-conducting plates 20 and the heat-dissipating pipes 21. Then start a plurality of fans 22, and through the plurality of fans 22, the heat can be quickly transferred to the external air, so that the temperature of the cooling box 16 can drop rapidly. Subsequently, start the oil pump 18. The oil pump 18 can pump out the heat-conducting oil with the temperature inside the cooling box 16 through the oil suction pipe 17 and transport it to the inside of the outer kettle 1 through the oil delivery pipe 19, so as to cool the raw materials for roxatidine reaction inside the inner kettle 2.
