For example, by setting a heating jacket outside the reaction kettle, steam or hot water is used for heating, or a cooling water circulation system is used to cool the reaction kettle. However, when the reaction kettle needs to be rapidly cooled in a short time, relying solely on the cooling water circulation may not achieve the desired cooling effect, leading to excessive reaction and affecting product quality. SUMMARY

[0022] The present application provides the following description with reference to the accompanying drawings to help comprehensively understand various embodiments of the present application as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize various changes and modifications to the various embodiments described herein without departing from the scope and spirit of the present application.

[0023] In the description of the present application, the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0024] It should be understood that when one element (e.g., a first element) is "connected" to another element (e.g., a second element), the element can be directly connected to the other element, or there can be an intervening element (e.g., a third element) between the element and the other element.

[0025] The embodiment of the present application provides a kind of reaction kettle temperature regulating system, as shown in Figures 1-5 It includes:

[0026] Reaction kettle body 100, reaction kettle body 100 is equipped with stirring cavity 110 and is equipped with temperature regulating cavity 120 in the outside of stirring cavity 110, reaction kettle body 100 includes shell 130, oil inlet 131 and oil outlet 132 are equipped on shell 130, oil inlet 131 and oil outlet 132 are connected with temperature regulating cavity 120 respectively;

[0027] Cooling oil tank 200, cooling oil tank 200 includes oil tank inlet 210 and oil tank outlet 220, oil tank inlet 210 is connected with oil outlet 132;

[0028] Cooling device 300, cooling device 300 is equipped in the top of cooling oil tank 200, and cooling device 300 is used to cool the outer surface of cooling oil tank 200.

[0029] The reaction kettle body 100 is provided with a stirring cavity 110 and a temperature adjusting cavity 120. The stirring cavity 110 is used for accommodating reaction materials and performing stirring operation, so as to ensure uniform reaction. The temperature adjusting cavity 120 surrounds the outside of the stirring cavity 110, and is used for adjusting the temperature of the materials in the stirring cavity 110 through heat conduction. The reaction kettle body 100 comprises an outer shell 130, which is provided with an oil inlet 131 and an oil outlet 132. The two interfaces are connected with the temperature adjusting cavity 120 respectively, and are used for conveying heating oil or cooling oil into the temperature adjusting cavity 120, so as to realize the increase or decrease of the temperature of the materials in the reaction kettle. The cooling oil tank 200 comprises a tank inlet 210 and a tank outlet 220, and the tank inlet 210 is connected with the oil outlet 132 of the reaction kettle body 100. This means that the oil (which can be heating oil or used heating oil) flowing out of the temperature adjusting cavity 120 of the reaction kettle will enter the cooling oil tank 200. The cooling device 300 is arranged at the top of the cooling oil tank 200, and its main function is to cool the outer surface of the cooling oil tank 200. By reducing the temperature of the outer surface of the cooling oil tank 200, the temperature of the cooling oil in the cooling oil tank 200 can be indirectly reduced, so as to realize the recycling of the cooling oil and provide low-temperature cooling oil required for temperature adjustment of the reaction kettle. Through reasonable design and component configuration, the reaction kettle temperature adjusting system can effectively adjust the temperature of the materials in the reaction kettle and ensure the smooth progress of the reaction process.

[0030] The working principle of the utility model is as follows:

[0031] When it is needed to cool the materials in the reaction kettle, cooling oil is conveyed into the temperature adjusting cavity 120 through the oil inlet 131. The cooling oil flows in the temperature adjusting cavity 120, absorbs the heat of the materials in the stirring cavity 110, and reduces the temperature of the materials. The used cooling oil flows out of the oil outlet 132 and enters the cooling oil tank 200.

[0032] As for the cooling oil tank 200, the cooling device 300 cools the outer surface of the cooling oil tank 200, prevents the cooling oil tank 200 from being high-temperature, and thus reduces the temperature of the cooling oil. Moreover, the cooling oil can be conveyed back to the temperature adjusting cavity 120 of the reaction kettle again, so as to realize the recycling of the cooling oil.

[0033] In some embodiments, the cooling device 300 comprises a main cooling water pipe 310, which is arranged along the length direction of the cooling oil tank 200. The main cooling water pipe 310 is provided with water spraying ports at intervals in the length direction of the main cooling water pipe 310.

[0034] The main cooling water pipe 310 is arranged along the length direction of the cooling oil tank 200. This arrangement enables the main cooling water pipe 310 to cover a larger surface area of the cooling oil tank 200, thereby more effectively cooling the cooling oil tank 200. Along the length direction of the main cooling water pipe 310, water outlets are arranged at intervals. The water outlets function to uniformly spray cooling water onto the outer surface of the cooling oil tank 200. In this way, the cooling water can directly contact the surface of the cooling oil tank 200, rapidly reducing the temperature of the cooling oil tank 200 and thereby the cooling oil, using the principle of water evaporation heat absorption. Through the design of the main cooling water pipe 310 and the water outlets, cooling water can be uniformly sprayed onto the outer surface of the cooling oil tank 200, rapidly reducing the temperature of the cooling oil tank 200 using the principle of water evaporation heat absorption, thereby improving the cooling efficiency. The structure of this cooling device 300 is relatively simple, mainly consisting of the main cooling water pipe 310 and the water outlets, making it easy to install and maintain. By recycling the cooling oil, the consumption of cooling oil is reduced, and energy consumption is also reduced, achieving certain energy-saving effects.

[0035] The working principle of the present embodiment is as follows:

[0036] When the cooling oil flows out of the temperature regulating cavity 120 of the reaction kettle and enters the cooling oil tank 200, the cooling device 300 begins to work. The cooling water in the main cooling water pipe 310 is uniformly sprayed onto the outer surface of the cooling oil tank 200 through the water outlets. The cooling water forms a water film on the surface of the cooling oil tank 200, and through water evaporation heat absorption, the heat on the surface of the cooling oil tank 200 is taken away, thereby reducing the temperature of the cooling oil tank 200. The cooled cooling oil can be transported back to the temperature regulating cavity 120 of the reaction kettle, realizing the recycling of the cooling oil and providing a sustained cooling effect for the materials in the reaction kettle.

[0037] Further, the cooling device 300 further comprises a water distribution pipe 320 connected to the main cooling water pipe 310, the water distribution pipe 320 extending along the width direction of the cooling oil tank 200, and a plurality of first water outlets 321 are arranged on the water distribution pipe 320, the first water outlets 321 being rotatably connected to the water distribution pipe 320.

[0038] The water distribution pipe 320 is connected with the main cooling water pipe 310, further expanding the distribution range of the cooling water. The water distribution pipe 320 extends along the width direction of the cooling oil tank 200, which means that the water distribution pipe 320 forms a grid-like layout with the main cooling water pipe 310, which can more comprehensively cover the surface of the cooling oil tank 200. The first sprinkler head 321 is installed on the water distribution pipe 320 and is rotatably connected with the water distribution pipe 320. This rotatable design enables the first sprinkler head 321 to adjust the direction and angle of water spraying as needed, thereby more flexibly controlling the spraying range of the cooling water. The water distribution pipe 320 is provided with a plurality of first sprinkler heads 321, which ensures that the cooling water can be uniformly sprayed to each part of the cooling oil tank 200, avoiding cooling dead angles and further improving the uniformity of the cooling effect.

[0039] Further, the water distribution pipe 320 is provided with an extension pipe 330, the end of the extension pipe 330 is directed towards the main cooling water pipe 310, and the end of the extension pipe 330 is rotatably connected with a second sprinkler head 331.

[0040] The extension pipe 330 is installed on the water distribution pipe 320, and the end thereof is directed towards the main cooling water pipe 310. This design further expands the spraying range of the cooling water, which can cover the area near the main cooling water pipe 310 and between the water distribution pipes 320. The end of the extension pipe 330 is directed towards the main cooling water pipe 310, which makes the cooling water more uniformly sprayed to the surface of the cooling oil tank 200, especially in the area between the main cooling water pipe 310 and the water distribution pipe 320, avoiding cooling dead angles. The second sprinkler head 331 is installed at the end of the extension pipe 330 and is rotatably connected with the extension pipe 330. This rotatable design enables the second sprinkler head 331 to adjust the direction and angle of water spraying as needed, further enhancing the flexibility of the cooling water spraying. The second sprinkler head 331 serves to supplement the cooling area between the main cooling water pipe 310 and the water distribution pipe 320, ensuring that the entire surface of the cooling oil tank 200 can be uniformly covered by the cooling water.

[0041] Further, the end of the water distribution pipe 320 is also provided with an inclined pipe 340, and the inclined pipe 340 is rotatably connected with a third sprinkler head 341.

[0042] The inclined pipe 340 is installed at the end of the water distribution pipe 320, and its direction forms an angle with the water distribution pipe 320, which can be directed towards the side or bottom of the cooling oil tank 200. This design enables the cooling water to cover the side and bottom areas of the cooling oil tank 200, further expanding the spraying range of the cooling water. The design of the inclined pipe 340 enables the cooling water to be sprayed to the side and bottom of the cooling oil tank 200, which are usually the parts with higher temperature and are easily overlooked. Through the inclined pipe 340, the cooling water can more evenly cover these areas, avoiding local overheating. The third sprinkler head 341 is installed on the inclined pipe 340 and is rotatably connected with the inclined pipe 340. This rotatable design enables the third sprinkler head 341 to adjust the direction and angle of water spraying as needed, further enhancing the flexibility of cooling water spraying. The function of the third sprinkler head 341 is to supplement the cooling area of the side and bottom of the cooling oil tank 200, ensuring that these areas are also evenly covered by the cooling water, further improving the uniformity of the cooling effect.

[0043] In some embodiments, a reaction kettle temperature regulation system further comprises a three-way valve 400, a first oil conveying device 500 and a second oil conveying device 600, the first oil conveying device 500 is used to convey heating oil, the second oil conveying device 600 is used to convey cooling oil, and the three-way valve 400 is connected with the reaction kettle body 100, the first oil conveying device 500 and the second oil conveying device 600 respectively.

[0044] The three-way valve 400 is used to switch and control the flow direction of the oil circuit. It is connected with the reaction kettle body 100, the first oil conveying device 500 and the second oil conveying device 600 respectively.

[0045] The working principle of the embodiment is as follows:

[0046] By adjusting the opening and closing position of the three-way valve 400, the delivery of heating oil or cooling oil to the temperature adjustment chamber 120 of the reaction kettle can be selected. This design enables the system to flexibly switch between heating and cooling modes according to the temperature requirements of the materials in the reaction kettle. When heating of the materials in the reaction kettle is required, heating oil is delivered through the oil inlet 131 into the temperature adjustment chamber 120, and the heating oil flows in the temperature adjustment chamber 120, transferring heat to the materials in the stirring chamber 110 through heat conduction, thereby increasing the temperature of the materials. The first oil delivery device 500 is used to deliver heating oil. It usually includes a heating oil tank, an oil pump and an oil pipeline, etc., responsible for delivering heated oil to the temperature adjustment chamber 120 of the reaction kettle. When heating of the materials in the reaction kettle is required, the first oil delivery device 500 is started, and the heating oil is delivered from the heating oil tank to the temperature adjustment chamber 120 of the reaction kettle through the oil pump. The heating oil flows in the temperature adjustment chamber 120, transferring heat to the materials in the stirring chamber 110 through heat conduction, thereby increasing the temperature of the materials. The second oil delivery device 600 is used to deliver cooling oil. It usually includes a cooling oil tank 200, an oil pump and an oil pipeline, etc., responsible for delivering cooling oil to the temperature adjustment chamber 120 of the reaction kettle. When cooling of the materials in the reaction kettle is required, the second oil delivery device 600 is started, and the cooling oil is delivered from the cooling oil tank 200 to the temperature adjustment chamber 120 of the reaction kettle through the oil pump. The cooling oil flows in the temperature adjustment chamber 120, absorbing the heat of the materials in the stirring chamber 110, thereby reducing the temperature of the materials. The first oil delivery device 500 and the second oil delivery device 600 are prior art, which will not be described here.

[0047] Further, the oil tank outlet 220 is connected to the second oil delivery device 600.

[0048] The cooling oil tank 200 is used to temporarily store used cooling oil. It is cooled by the cooling device 300 (such as the main cooling water pipe 310, the branch pipe 320, the sprinkler head, etc.) to make it able to be recycled. The inlet of the cooling oil tank 200 is connected to the oil outlet 132 of the reaction kettle, and the outlet is connected to the second oil delivery device 600. By connecting the outlet of the cooling oil tank 200 to the second oil delivery device 600, the recycling of cooling oil is realized, reducing the consumption of cooling oil and reducing the operating cost. After being cooled by the cooling device 300 in the cooling oil tank 200, the cooling oil can enter the temperature adjustment chamber 120 of the reaction kettle again at a lower temperature, improving the cooling efficiency. The recycling of cooling oil reduces the dependence on fresh cooling oil, making the system more stable and reducing the risk of shutdown due to insufficient supply of cooling oil. The recycling of cooling oil reduces the emission of cooling oil, which is more friendly to the environment.
