During the heat exchange process, there is a temperature difference between the inside and outside, which means that there is room for further improvement in the uniformity of the heat exchange process.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-3 In this embodiment of the present invention, a reaction vessel capable of uniform heating includes a vessel body 1, a jacket 2 welded to the outer wall of the vessel body 1, a rotary motor 5 fixedly installed at the center of the top cover of the vessel body 1, a stirrer 7 extending into the interior of the vessel body 1 installed at the output end of the rotary motor 5, a temperature sensor 6 penetrating into the interior of the vessel body 1 installed at the top of the vessel body 1, the temperature sensor 6 being located outside the rotary motor 5 and the stirrer 7, a first heat exchange component being provided on the outer periphery of the vessel body 1, and a second heat exchange component connected to the first heat exchange component being installed on the inner periphery of the jacket 2.
[0016] In this embodiment: During the reaction, heat transfer oil is added through the second heat exchange component. After being added, the heat transfer oil flows within the first and second heat exchange components. Its temperature is exchanged between the vessel body 1 and its interior. Through the heat exchange between the first and second heat exchange components, more efficient heat exchange can be achieved. It can also prevent the heat transfer oil from being continuously cut and re-overlapped by the second heat exchange component during the flow process. This ensures that the temperature of the heat transfer oil does not differ between the inside and outside during the flow process, thus avoiding the problem of uneven heat exchange.
[0017] Please refer to this carefully. Figure 2 The first heat exchange component includes an annular groove 8 formed on the outer periphery of the vessel body 1. A spiral plate 9 is welded to the circumferential wall of the annular groove 8. A reinforcing rod 10, which is fixedly connected to the spiral plate 9, is welded between the bottom end and the top end of the inner wall of the annular groove 8. The spiral plate 9 has a double spiral structure.
[0018] In this embodiment: During the flow of heat transfer oil, the part of the vessel body 1 along the spiral path of the heat transfer oil flow has a thinner outer shell due to the opening of the annular groove 8. In order to avoid the problem of reduced strength of the vessel body 1 caused by the opening of the annular groove 8, the reinforcing rod 10 and the spiral plate 9 are set so that when the vessel body 1 is under force, the force is transmitted to the spiral plate 9 and the reinforcing rod 10, thus avoiding the problem of reduced strength of the vessel body 1 caused by the opening of the annular groove 8.
[0019] Please refer to this carefully. Figure 2 and Figure 3 The second heat exchange assembly includes a heat exchange tube 11 installed inside the jacket 2. The heat exchange tube 11 is arranged in a spiral pattern. The inlet end of the heat exchange tube 11 is equipped with an inlet 3 that extends to the outside of the jacket 2, and the outlet end of the heat exchange tube 11 is equipped with an outlet 4 that extends to the outside of the jacket 2. The inner wall of the heat exchange tube 11 is welded with a first staggered plate 12 and a second staggered plate 13 distributed along the inner wall of the heat exchange tube 11. The first staggered plate 12 and the second staggered plate 13 are staggered and welded, and the first staggered plate 12 and the second staggered plate 13 are arranged in a perpendicular state. The second staggered plate 13 protrudes inward and is staggered with the reinforcing rod 10. The inner circumference of the heat exchange tube 11 is open, and the inner opening of the heat exchange tube 11 is opposite to the annular groove 8. The spiral trajectory of the heat exchange tube 11 matches the spiral trajectory of the spiral plate 9, and the inner circumference of the heat exchange tube 11 is welded to the outer circumference of the spiral plate 9.
[0020] In this embodiment: after the heat transfer oil enters the heat exchange tube 11 through the inlet 3, the heat transfer oil flows into the inner side of the spiral plate 9 through the opening on the inner side of the heat exchange tube 11 and comes into contact with the outer wall of the vessel body 1 for heat exchange. During the flow of the heat transfer oil, it continuously comes into contact with the staggered first staggered plate 12 and the second staggered plate 13. Therefore, the heat transfer oil is continuously divided, merged, re-divided, and re-merged during the spiral flow. This ensures that the heat transfer oil is constantly being stirred during the heat exchange process. Therefore, there will be no temperature difference between the inside and outside of the heat transfer oil during the spiral flow, thus ensuring the uniformity of the heat exchange process.
[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
