[0020] Reference Figure 1-4 A cooling device for a chemical reactor includes a reactor body 1, a support frame 2 fixedly connected to the surface of the reactor body 1, a tank cover 3 fixedly connected to the top surface of the reactor body 1, a feed pipe 4 fixedly connected to the inner wall of the tank cover 3, a discharge pipe 5 fixedly connected to the inner wall of the reactor body 1, a solenoid valve 6 fixedly connected to the inner wall of the discharge pipe 5, a cooling pipe 7 fixedly connected to the inner wall of the reactor body 1 and the cooling pipe 7 fixedly connected to the inner wall of the tank cover 3, a liquid storage tank 8 fixedly connected to the surface of the reactor body 1, and a refrigeration mechanism inside the liquid storage tank 8. The refrigeration mechanism consists of a temperature guide plate 9, semiconductor cooling chips 10, a fan shroud 11, and a cooling fan 12. Multiple semiconductor cooling chips 10 are located inside the temperature guide plate 9 to absorb and reduce the temperature of the coolant, thereby improving the refrigeration efficiency. The temperature guide plate 9 is fixedly connected to the inner wall of the liquid storage tank 8. The conductor cooling plate 10 is fixedly connected to the inner wall of the temperature conducting plate 9, the fan shroud 11 is fixedly connected to the left side of the liquid storage tank 8, and the cooling fan 12 is fixedly connected to the inner wall of the fan shroud 11. This is used to reduce the temperature of the coolant and improve the cooling efficiency. The liquid storage tank 8 is equipped with a water circulation assembly, which consists of a suction pipe 13, a water pump 14, and a return pipe 15. The suction pipe 13 is fixedly connected to the inner wall of the liquid storage tank 8, and the outlet end of the suction pipe 13 is fixedly connected to the inlet end of the cooling pipe 7. The water pump 14 is fixedly connected to the inner wall of the suction pipe 13 and the top surface of the liquid storage tank 8. The outlet end of the return pipe 15 is fixedly connected to the inner wall of the liquid storage tank 8, and the inlet end of the return pipe 15 is fixedly connected to the outlet end of the cooling pipe 7. This is used to draw coolant for circulation, which facilitates continuous cooling. The tank cover 3 is equipped with a stirring reaction mechanism, and the reaction vessel body 1 is equipped with a drive assembly on its surface.

[0021] Specifically, the stirring reaction mechanism consists of a stirring frame 16, a limiting ring 17, and a heating rod 18. The limiting ring 17 is circular and made of metal. The limiting ring 17 made of metal has higher strength, is less prone to deformation and damage under stress, and is more durable. The stirring frame 16 is rotatably connected to the inner wall of the tank cover 3. The inner wall of the limiting ring 17 is fixedly connected to the surface of the stirring frame 16, and the limiting ring 17 is rotatably connected to the inner wall of the tank cover 3. The heating rod 18 is fixedly connected to the inner wall of the stirring frame 16 and is used to heat the raw materials. At the same time, it facilitates stirring of the raw materials and improves reaction efficiency.

[0022] Specifically, the drive assembly consists of a servo motor 19, a drive wheel 20, a transmission belt 21, and a driven wheel 22. The servo motor 19 is fixedly connected to the surface of the reactor body 1, the drive wheel 20 is fixedly connected to the output end of the servo motor 19, the transmission belt 21 meshes with the inner wall of the drive wheel 20, and the inner wall of the driven wheel 22 is fixedly connected to the surface of the stirring frame 16, and the inner wall of the driven wheel 22 meshes with the transmission belt 21, which is used to drive the stirring reaction mechanism to rotate, thereby improving the heating uniformity.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In operation: First, the raw material is injected into the reactor body 1 through the feed pipe 4. The heating rod 18 is activated to heat the raw material through the stirring frame 16. At the same time, the servo motor 19 is activated to drive the drive wheel 20 and the transmission belt 21 to rotate. Through the engagement of the transmission belt 21 and the driven wheel 22, the stirring frame 16 and the limiting ring 17 rotate along the inner wall of the tank cover 3. The rotation of the stirring frame 16 can stir and heat the raw material for reaction. When cooling is required after the reaction is completed, the semiconductor cooling chip 10 is activated to absorb and release heat. The heat-absorbing end of the 10 absorbs heat from the heat-conducting plate 9 and the internal heat storage tank 8, thereby reducing the temperature of the coolant inside the heat storage tank 8. The heat dissipation fan 12 is started, and the heat dissipation end of the semiconductor cooling chip 10 is cooled through the fan cover 11. The water pump 14 is started, and the low-temperature coolant is drawn into the cooling pipe 7 through the suction pipe 13. Through the temperature conduction performance of the cooling pipe 7, the high-temperature raw material and the low-temperature coolant can be cooled by heat exchange. At the same time, the coolant after the temperature rises flows back to the heat storage tank 8 through the return pipe 15, so as to carry out the circulating cooling and cooling work.

[0025] In summary, this cooling device for a chemical reactor injects raw materials into the reactor body 1 through the feed pipe 4. The drive assembly is activated to stir and heat the raw materials via the stirring reaction mechanism. When cooling is required after the reaction is complete, the refrigeration mechanism is activated to lower the temperature of the coolant inside the storage tank 8. The water circulation assembly is activated to draw low-temperature coolant into the cooling pipe 7, thus exchanging heat between the high-temperature raw materials and the low-temperature coolant. Simultaneously, the coolant flows back to the storage tank 8 through the water circulation assembly, achieving rapid cooling of the reacted raw materials in the reactor. This avoids the problem of low cooling rates in existing reactor cooling devices, which makes it difficult to quickly cool high-temperature raw materials, and solves the problems mentioned in the background art.
