[0030] Referring to Figure 1 , a thermal circulation mechanism includes: a kettle body 100, a temperature control mechanism 500, and a condensation mechanism 400; the temperature control mechanism 500 is arranged on the inner wall and / or outer wall of the kettle body 100, and the temperature control mechanism 500 can heat up and / or cool down the interior of the kettle body 100; the condensation mechanism 400 is arranged on the kettle body 100, the condensation mechanism 400 is connected to the upper part of the kettle body 100 and is used to receive the volatile gas in the kettle body 100, and the condensation mechanism 400 is used to condense the volatile gas; the condensation mechanism 400 is connected to the temperature control mechanism 500 and can perform heat exchange with the temperature control mechanism 500. When various solvents react in the kettle body 100, the temperature control mechanism 500 can heat up or cool down the interior of the kettle body 100, so that the temperature in the kettle body 100 can approach the temperature suitable for chemical reactions. During the chemical reaction process, volatile gases will be generated, and the volatile gases will flow to the condensation mechanism 400 under the action of air pressure and perform condensation operations at the condensation mechanism 400. During the condensation process, the heat carried by the volatile gas will perform heat exchange between the condensation mechanism 400 and the temperature control mechanism 500, so that the temperature control mechanism 500 obtains heat supplement from the volatile gas, and enables the volatile gas to perform condensation operations more smoothly. Moreover, the temperature control mechanism 500 can obtain heat supplement, thereby reducing the demand for energy, and effectively achieving the effect of reducing energy consumption.
[0031] In some embodiments, referring to Figure 3, the temperature control mechanism 500 includes a heat exchange water pipe 550 disposed on the outer periphery of the kettle body 100. The heat exchange water pipe 550 contacts the peripheral wall of the kettle body 100 and can perform heat exchange with it. Cold water or hot water can flow in the heat exchange water pipe 550, and heat exchange is performed between the cold water or hot water and the peripheral wall of the kettle body 100, so as to achieve the effect of heating or cooling the kettle body 100, and then facilitate adjusting the temperature in the kettle body 100 to the target range.
[0032] It can be envisioned that the temperature control mechanism 500 can also be composed of other components. For example, an electric heating plate can be directly installed at the bottom of the kettle body 100, and the kettle body 100 can be directly heated through the electric heating plate. Therefore, the specific implementation manner of the temperature control mechanism 500 is not unique, but can be adjusted according to the actual situation and is not limited here.
[0033] In some embodiments, referring to Figure 3 , the heat exchange water pipe 550 is reciprocally wound around the outer peripheral wall of the kettle body 100. The heat exchange water pipe 550 forms a spiral shape on the outer peripheral wall of the kettle body 100 and extends from the upper part of the kettle body 100 to the lower part of the kettle body 100. The reciprocally winding effect of the heat exchange water pipe 550 in a spiral shape can effectively increase the contact area between the heat exchange water pipe 550 and the kettle body 100. Therefore, the heat exchange effect between the heat exchange water pipe 550 and the kettle body 100 can be effectively strengthened, and then higher heat conduction efficiency and temperature control efficiency can be brought.
[0034] In some embodiments, referring to Figure 2 , the condensation mechanism 400 includes a first condensation tower 430. The first condensation tower 430 is provided with a first connection part 433 and a second connection part 437. The first connection part 433 is connected to the top of the kettle body 100, and the second connection part 437 is connected to the inside of the kettle body 100. The first condensation tower 430 can receive the volatile gas from the inside of the kettle body 100 through the first connection part 433, so that it can smoothly flow into the first condensation tower 430 and contact and condense with the inner wall of the first condensation tower 430. The liquid formed after condensation can flow back into the kettle body 100 through the second connection part 437, so that the recovery and reuse operation of the solvent can be successfully completed.
[0035] It can be envisioned that a refrigerant for accelerating condensation, such as an ice pack, can be placed on the outer peripheral wall of the first condensation tower 430 to improve the operation efficiency of the condensation operation. The specific implementation manner can be adjusted according to actual needs and is not limited here.
[0036] In some embodiments, referring to Figure 4, the first condensation tower 430 has an inner flow layer 431 and an outer flow layer 432 that are isolated from each other, and both the inner flow layer 431 and the outer flow layer 432 are used for fluid flow; the first connection part 433 and the second connection part 437 are both connected to the inner flow layer 431, and the temperature control mechanism 500 is connected with a third connection part 439, and the third connection part 439 is connected to the outer flow layer 432. When the first condensation tower 430 is working, the fluid to be condensed will flow in its inner flow layer 431, and the heat exchange fluid coming through the third connection part 439 will flow at the outer flow layer 432. The fluid to be condensed can exchange heat with the heat exchange fluid through the first condensation tower 430, so as to achieve the effect of accelerating condensation, and can also effectively supplement the heat to the temperature control mechanism 500 through the heat exchange fluid, so as to achieve the effect of energy reuse, and further help to reduce the overall energy consumption of the reaction kettle.
[0037] Specifically, the inner flow layer 431 and the outer flow layer 432 are isolated by a heat-conducting cylinder wall, and heat conduction and heat exchange operations are carried out by using this cylinder wall.
[0038] In some embodiments, referring to Figure 4 , the first connection part 433 is located above the second connection part 437. After the volatile gas is condensed, it will form a liquid, and the liquid is likely to fall under the action of its own weight and fall to the bottom of the first condensation tower 430. Therefore, the positional relationship between the first connection part 433 and the second connection part 437 can directly and effectively distinguish between the volatile gas entering the first condensation tower 430 and the solution leaving the first condensation tower 430, so as to facilitate the separate treatment effect of the two.
[0039] In some embodiments, referring to Figure 2 , the top of the first condensation tower 430 is connected with a second condensation tower 450, the second condensation tower 450 extends upward toward the first condensation tower 430, and a recovery pipe is arranged at the bottom of the second condensation tower 450. The second condensation tower 450 can effectively cooperate with the first condensation tower 430 to extend the flow path of the volatile gas, so that the volatile gas can have more opportunities to contact the inner wall of the first condensation tower 430 or the second condensation tower 450, and then effectively increase the amount of condensation of the volatile gas, so as to ensure that the volatile gas is fully condensed.
[0040] In some embodiments, referring to Figure 1 , a stirring device 700 is arranged in the kettle body 100, and the stirring device 700 can stir the fluid in the kettle body 100. The stirring device 700 can stir the solution in the kettle body 100, so as to accelerate the interaction between the solutions, and then effectively improve the reaction efficiency.
[0041] In some embodiments, referring to Figure 2, the stirring device 700 includes a motor. A rotating shaft 710 is arranged in the kettle body 100, and the rotating shaft 710 is connected to the motor; a stirring paddle 720 is arranged on the outer periphery of the rotating shaft 710 and can drive the stirring paddle 720 to rotate together. After the motor is started, the stirring paddle 720 can be driven to rotate through the rotating shaft 710, so that the stirring paddle 720 can stir various solvents in the kettle body 100, thereby achieving the effect of increasing the reaction rate.
[0042] The second aspect of the present invention provides a reaction kettle, including the above heat circulation mechanism. When various solvents react in the kettle body 100, the temperature control mechanism 500 can heat up or cool down the inside of the kettle body 100, so that the temperature in the kettle body 100 can approach the temperature suitable for chemical reactions. During the chemical reaction process, volatile gases will be generated, and the volatile gases will flow to the condensation mechanism 400 under the action of air pressure and perform condensation operations at the condensation mechanism 400. During the condensation process, the heat carried by the volatile gases will be exchanged through heat exchange between the condensation mechanism 400 and the temperature control mechanism 500, so that the temperature control mechanism 500 can obtain heat supplementation from the volatile gases and enable the volatile gases to condense more smoothly. Moreover, the temperature control mechanism 500 can obtain heat supplementation, thereby reducing the demand for energy and effectively achieving the effect of reducing energy consumption.
[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0044] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
