Background Art

[0002] A heat-conducting oil reaction kettle mainly consists of a kettle body, a stirring device, a heating and cooling system, a sealing device, etc. The kettle body is usually made of materials such as stainless steel, with good corrosion resistance and pressure resistance. The stirring device is used to fully mix the reaction materials and improve the reaction efficiency. The heating and cooling system generally uses heat-conducting oil as the heat transfer medium, and the heat-conducting oil is circulated between the jacket of the reaction kettle and the heating furnace through a circulation pump to achieve heating and cooling of the reaction kettle. The sealing device ensures the sealing of the reaction kettle during operation and prevents material leakage.

[0003] The specification of Chinese Patent CN215864062U discloses a heat-conducting coil for a reaction kettle, which includes an inner heat-conducting oil coil, an external semi-circular coil and a heat-conducting oil furnace arranged coaxially; the external semi-circular coil is wrapped outside the inner heat-conducting oil coil and fixedly wound around the outer wall of the reaction kettle. The addition of the external semi-circular coil and the heat-insulating layer can make the hot oil achieve a better heat-insulating effect, thereby improving the heat utilization of the heating equipment, avoiding rapid dissipation and loss of heat, and reducing the use cost.

[0004] During the experiment, when the high-temperature constant-temperature time of the reaction kettle ends, the current cooling method of the heat-conducting oil completely depends on natural cooling, which often takes a lot of time. Due to the slow cooling speed, on the one hand, it will have an adverse effect on the purity of the reaction product. On the other hand, the slow cooling process also greatly affects the experimental efficiency, and at the same time increases the time cost and resource consumption of the experiment. Content of the Utility Model

[0005] Aiming at the above-mentioned prior art, the technical problem to be solved by the present utility model is that during the experiment, when the high-temperature constant-temperature time of the reaction kettle ends, the current cooling method of the heat-conducting oil completely depends on natural cooling, which often takes a lot of time. Due to the slow cooling speed, on the one hand, it will have an adverse effect on the purity of the reaction product. On the other hand, the slow cooling process also greatly affects the experimental efficiency, and at the same time increases the time cost and resource consumption of the experiment.

[0006] To solve the above problems, the present utility model provides a heat-conducting oil circulation device for a reaction kettle that can rapidly cool down, which includes a reaction kettle body. An outer jacket layer is fixedly connected to the outer end of the reaction kettle body. A serpentine coil is installed inside the outer jacket layer and the reaction kettle body.

A first temperature-sensitive deformation wire is fixedly connected to the rear end of the fixing block. A displacement collar is fixedly connected to the rear ends of two corresponding first temperature-sensitive deformation wires.

[0007] In the above heat-conducting oil circulation device for a reaction kettle that can rapidly cool down, in this solution, the heat-conducting oil circulates between the serpentine coil in the outer jacket layer and the cooler through the circulating pump in the serpentine coil, realizing the rapid cooling of the reaction kettle body, effectively guaranteeing the time cost and resource consumption of the experiment of the reaction kettle body. At the same time, a plurality of self-cleaning mechanisms are arranged inside the serpentine coil, reducing the corrosion of the inner wall of the serpentine coil by dirt and deposits.

[0008] As a further improvement of the present application, valves are installed at both the output end and the input end of the heater and the cooler. The output end and the input end of the heater and the cooler are connected to the heater through the corresponding valves.

[0009] As a further improvement of the present application, a fitting outer ring is fixedly connected to the outer end of the displacement collar.

[0010] As a further improvement of the present application, the fitting outer ring is in contact with the inner side wall of the serpentine coil. A plurality of arc-shaped slots are formed on the outer side of the fitting outer ring.

[0011] As another improvement of the present application, the plurality of arc-shaped slots are arranged in an annular equidistant manner. A sliding push block is slidably connected to the inner end of the arc-shaped slot.

[0012] As a supplementary improvement of the present application, a protruding tooth block is fixedly connected to the upper end of the sliding push block. The protruding tooth block is in contact with the inner side wall of the serpentine coil.

[0013] As a supplementary improvement of the present application, a second temperature-sensitive deformation wire is fixedly connected to the left inner wall of the arc-shaped slot. One end of the second temperature-sensitive deformation wire close to the sliding push block is connected to the sliding push block.

[0014] In summary, in this solution, the heat-conducting oil circulates between the serpentine coil and the cooler through the circulating pump in the serpentine coil, realizing the rapid cooling of the reactor body, effectively ensuring the time cost and resource consumption of the reactor body experiment. At the same time, multiple self-cleaning mechanisms are arranged in the serpentine coil. When the self-cleaning mechanism passes through the heat-conducting oil at two temperatures in the serpentine coil, the first temperature-sensitive deformation wire automatically changes its stretching form by contacting the high-temperature or low-temperature heat-conducting oil, thereby pushing the displacement collar to scrape back and forth along the inner side wall of the serpentine coil, effectively and timely removing the dirt and sediment on the inner wall of the serpentine coil, reducing the corrosion of the dirt and sediment on the inner wall of the serpentine coil. The self-cleaning mechanism can greatly reduce the need for manual cleaning, thus reducing the maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following describes the two embodiments of the present application in detail with reference to the drawings.

[0025] The first embodiment:

[0026] Figure 2-6 A heat-conducting oil circulation device for a reactor that can quickly cool down is shown, including a reactor body 1. A jacket sandwich 2 is fixedly connected to the outer end of the reactor body 1. A serpentine coil 3 is installed at the inner ends of the jacket sandwich 2 and the reactor body 1. A circulation outer pipe 5 is externally connected to the serpentine coil 3. A circulation pump 4, a heater 7 and a cooler 6 are sequentially installed in the circulation outer pipe 5. A plurality of self-cleaning mechanisms are arranged inside the serpentine coil 3. The self-cleaning mechanism includes a pair of fixing blocks 9 arranged on the upper and lower inner walls of the serpentine coil 3. A first temperature-sensitive deformation wire 10 is fixedly connected to the rear end of the fixing block 9. A displacement sleeve 11 is fixedly connected to the rear ends of two corresponding first temperature-sensitive deformation wires 10.

[0027] Figure 2-6 It is shown that valves 8 are installed at both the output end and the input end of the heater 7 and the cooler 6. The output end and the input end of the heater 7 and the cooler 6 are connected to the heater 7 through the corresponding valves 8. A fitting outer ring 12 is fixedly connected to the outer end of the displacement sleeve 11. The fitting outer ring 12 is in contact with the inner side wall of the serpentine coil 3. A plurality of arc-shaped grooves 13 are formed on the outer side of the fitting outer ring 12. The plurality of arc-shaped grooves 13 are arranged in an annular equidistant manner. A sliding push block 15 is slidably connected to the inner end of the arc-shaped groove 13. A protruding tooth block 16 is fixedly connected to the upper end of the sliding push block 15. The protruding tooth block 16 is in contact with the inner side wall of the serpentine coil 3.

[0028] Figure 1-6It shows that in this solution, the heat-conducting oil in the serpentine coil 3 circulates between the serpentine coil 3 in the jacket sandwich 2 and the cooler 6 through the circulation pump 4. When the reactor body 1 needs to be cooled down, the heat-conducting oil carries the heat in the reactor body 1 into the cooler 6 and exchanges heat with the cooling medium, so as to quickly reduce the temperature of the heat-conducting oil. The cooled heat-conducting oil is then sent back to the serpentine coil 3 by the circulation pump 4 to continue absorbing the heat in the reactor body 1. This cycle repeats to achieve the rapid cooling of the reactor body 1, effectively ensuring the time cost and resource consumption of the experiment of the reactor body 1. At the same time, multiple self-cleaning mechanisms are arranged in the serpentine coil 3. When the self-cleaning mechanism passes through the heat-conducting oil at two temperatures in the serpentine coil 3, the first temperature-sensitive deformation wire 10 contacts the high-temperature or low-temperature heat-conducting oil and automatically changes its stretching form, thereby pushing the displacement collar 11 to scrape back and forth along the inner side wall of the serpentine coil 3 in the serpentine coil 3, effectively and timely removing the dirt and deposits on the inner wall of the serpentine coil 3, reducing the corrosion of the inner wall of the serpentine coil 3 by the dirt and deposits. The self-cleaning mechanism can greatly reduce the need for manual cleaning, thereby reducing the maintenance cost. And multiple protruding tooth blocks 16 are arranged on the outer side of the fitting outer ring 12, increasing the friction force between the wiping surface and the object to be scraped. The multiple protruding tooth blocks 16 form a reinforcement layer between the fitting outer ring 12 and the inner wall of the serpentine coil 3. The tip of each protruding tooth block 16 can concentrate the force on the residue in the serpentine coil 3, and the friction force is increased, thereby enhancing the scraping strength.

[0029] The second implementation mode:

[0030] Figure 2 , Figure 7 It shows a heat-conducting oil circulation device for a reactor that can quickly cool down. The left inner wall of the arc-shaped slot 13 is fixedly connected with a second temperature-sensitive deformation wire 14. One end of the second temperature-sensitive deformation wire 14 close to the sliding push block 15 is connected to the sliding push block 15. And an arc-shaped slot 13 is arranged between the fitting outer ring 12 and the protruding tooth block 16. The second temperature-sensitive deformation wire 14 in the arc-shaped slot 13 can also change its stretching form according to the temperature of the heat-conducting oil in the serpentine coil 3, thereby pushing the protruding tooth block 16 to move left and right in the arc-shaped slot 13. When the protruding tooth block 16 moves, it can ensure that every part of the residue in the serpentine coil 3 is evenly treated.

[0031] Combined with the current actual needs, the above implementation modes adopted in this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
