DETAILED DESCRIPTION

[0036] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned description of the drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0037] Example: Please refer to Figure 1-Figure 5 In an embodiment of the present invention, a polyurethane grafted polyether silicone preparation reactor with precise temperature control is provided, comprising:

[0038] The kettle body 1 has a feed port, through which quantitative feeding is achieved. In addition, the kettle body 1 can also be equipped with safety devices, control systems and other auxiliary equipment to ensure the safe operation of the equipment and the smooth progress of production, which will not be repeated here;

[0039] a water bath 3, used to carry the kettle body 1 and provide a constant temperature water bath temperature adjustment for the kettle body 1 from the outside; and a temperature control tube 2, which is rotatably arranged inside the kettle body 1 and provides a temperature adjustment for the kettle body 1 from the inside;

[0040] During the preparation, the temperature control tube 2 is selectively driven to rotate to achieve uniformity of the material body and temperature;

[0041] Furthermore, the material homogenization achieved by the temperature control tube 2 is positively correlated with the temperature homogenization.

[0042] In this embodiment, the water bath 3 and the temperature control tube 2 cooperate with each other to achieve efficient control of the internal temperature of the kettle body 1 .

[0043] The water bath 3 is placed outside the kettle body 1, providing a stable and uniform constant temperature water bath temperature regulation. This constant temperature water bath temperature control not only ensures the stability of temperature control, but also helps to reduce the impact of external environmental factors on the reaction process.

[0044] The temperature control tube 2 is located inside the kettle body 1, can respond to temperature changes quickly, and directly participate in the temperature control process. Due to its fast temperature control speed, the temperature control tube 2 is particularly important when dealing with emergencies or when the temperature needs to be adjusted quickly.

[0045] This internal and external combined temperature control method enables the water bath 3 and the temperature control tube 2 to complement each other, give full play to their respective advantages, and thus improve the temperature control effect of the kettle body 1 to the best state.

[0046] It is worth mentioning that the temperature control tube 2 in this embodiment is designed to be rotatable. This design not only allows the temperature control tube 2 to adjust its position as needed to contact the material body at different positions, but also helps to reduce heat accumulation and ensure more uniform temperature control.

[0047] At the same time, the temperature control tube 2 can also play a role in stirring the material during the rotation process, which greatly simplifies the process flow in actual operation and makes it unnecessary to configure additional stirring equipment in the kettle body 1. This design innovation not only optimizes the structure of the equipment, but also improves production efficiency and convenience of operation.

[0048] That is to say, this embodiment achieves efficient and uniform control of the temperature inside the kettle body 1 by cleverly combining the functions of the water bath 3 and the temperature control tube 2 and giving full play to the advantages of the rotatable temperature control tube 2. This not only improves product quality and production efficiency, but also simplifies the process flow and equipment structure.

[0049] Furthermore, the temperature control tube 2 is a snake-like structure, and its ends are correspondingly connected with a liquid outlet pipe 4 and a liquid inlet pipe 5 . The liquid outlet pipe 4 and the liquid inlet pipe 5 both horizontally penetrate the kettle body 1 and are sealed and rotatably connected to the kettle body 1 .

[0050] It should be clear that by configuring the temperature control tube 2 as a serpentine structure, on the one hand, this structure not only significantly increases the temperature control area of ​​the temperature control tube 2, allowing it to contact the material in the kettle body 1 more widely, ensuring uniform temperature distribution and efficient regulation, but also significantly enhances its stirring function. The serpentine structure greatly increases the stirring area, so that the material is subjected to more shear force and friction when flowing in the tube, thereby improving the mixing effect.

[0051] In addition, the snake-like structure makes the stirring path more complicated. The material not only moves in a straight line in the tube, but also changes direction frequently. This multi-directional flow pattern makes the material mixing more uniform, greatly improving the stirring efficiency. Therefore, this design not only optimizes the temperature control effect, but also improves the stirring performance, providing a strong guarantee for the efficient conduct of chemical reactions.

[0052] Furthermore, the temperature control tube 2 is a heat conduction tube, and a plurality of first plates 14 are vertically connected to its outer surface, and the ends of the first plates 14 are vertically connected to the second plates 15, and the second plates 15 are parallel to the temperature control tube 2;

[0053] The second plate body 15 is concave.

[0054] The first plate 14 is used to provide connection and support for the second plate 15 , and the second plate 15 can improve the pushing and stirring effects on the material.

[0055] In addition, the first plate 14 is configured to extend the temperature control tube 2, thereby further increasing the heat conduction area.

[0056] In the current reactor technology, there are also certain challenges in temperature monitoring. Traditional temperature sensors are directly exposed to the material body for a long time, which not only puts extremely high requirements on the sealing, corrosion resistance and structural strength of the sensor, but also when the temperature control tube 2 is in a static state, heat is easily accumulated locally, resulting in the measurement accuracy of the temperature sensor being affected. This traditional temperature measurement method not only limits the service life of the temperature sensor, but may also have a negative impact on the stability and efficiency of the entire reaction process.

[0057] In order to solve these problems, in this embodiment, a lap frame 6 is also fixed on the temperature control tube 2, and a temporary storage container 7 is rotatably arranged on the lap frame 6. The center of gravity of the temporary storage container 7 is lower than the lap frame 6, and a temperature sensor 8 corresponding to the temporary storage container 7 is also arranged on the top of the kettle body 1. Then, in the process of driving the temperature control tube 2 to rotate, the temporary storage container 7 will store the material and send it to a position close to the temperature sensor 8, and the temperature will be measured by the temperature sensor 8. Under normal circumstances, the temperature sensor 8 may not be immersed in the material. In this way, the temperature sensor 8 can measure the temperature without directly immersing in the material, thereby significantly improving its service life and measurement stability.

[0058] In addition, this embodiment further improves the accuracy of temperature measurement. By embedding a copper tube in the middle of the temporary storage container, when the container with the material body rotates to a position close to the temperature sensor 8, the end of the copper tube can directly contact the temperature sensor 8, thereby achieving more accurate temperature measurement.

[0059] In this embodiment, the water in the temperature control tube 2 is provided by the water bath 3, and the water bath 3 also wraps the kettle body 1. The part of the kettle body 1 wrapped by the water bath 3 is made of heat-conducting material, and a temperature controller 13 is also provided in the water bath 3.

[0060] A data recording module is also provided on one side of the kettle body 1, through which by-product information of the by-products in the kettle body 1 is collected;

[0061] Determine the temperature adjustment range according to the trend change of by-products;

[0062] The temperature of the kettle body 1 is collected by the temperature sensor 8 to obtain a temperature collection data set;

[0063] generating a temperature adjustment parameter according to the temperature adjustment interval and the temperature acquisition data set;

[0064] The temperature of the kettle body 1 is adjusted according to the temperature adjustment parameters.

[0065] Specifically, the data recording module is arranged on one side of the kettle body 1, and its main function is to collect and record the information of by-products in the kettle. By-products are other compounds produced in addition to the target product in the chemical reaction, and their production amount, type and trend can provide important feedback for the reaction process; by analyzing the by-product information collected by the data recording module, the data recording module can identify the trend change of by-product generation. Such changes may be caused by various factors such as temperature, pressure, material ratio, etc.

[0066] The purpose of determining the temperature adjustment interval is to find an optimal temperature range, within which the amount of by-products generated can be controlled to a minimum, thereby improving the purity and quality of the target product;

[0067] Through the temperature sensor, the data recording module can collect the temperature data in the kettle body 1 in real time to form a temperature collection data set;

[0068] According to the previously determined temperature adjustment interval and temperature acquisition data set, the data recording module can generate temperature adjustment parameters. The temperature adjustment parameters are the basis for guiding how to adjust the temperature in the reactor to ensure that the reaction is carried out within the optimal temperature range.

[0069] In addition, a first temperature adjustment threshold is generated based on the temperature control effect of the water bath 3, and a first temperature warning interval is determined by the temperature adjustment interval and the first temperature adjustment threshold;

[0070] generating a second temperature adjustment threshold based on the temperature control effect of the temperature control tube 2, and determining a second temperature warning interval through the temperature adjustment interval and the second temperature adjustment threshold;

[0071] generating a third temperature adjustment threshold based on the temperature control effect of the water bath 3 and the temperature control effect of the temperature control tube 2, and determining a third temperature warning interval through the temperature adjustment interval and the third temperature adjustment threshold;

[0072] A temperature adjustment parameter is generated based on the temperature collection data set, the first temperature warning interval, the second temperature warning interval, and the third temperature warning interval.

[0073] More specifically, when there is a temperature in the temperature collection data set that meets the first temperature warning interval, the first temperature adjustment parameter is generated, and the temperature in the kettle body 1 is adjusted according to the first temperature adjustment parameter;

[0074] When there is a temperature in the temperature collection data set that meets the second temperature warning interval, the second temperature adjustment parameter is generated, and the temperature in the kettle body 1 is adjusted according to the second temperature adjustment parameter;

[0075] When there is a temperature in the temperature collection data set that meets the third temperature warning interval, the third temperature adjustment parameter is generated, and the temperature in the kettle body 1 is adjusted according to the third temperature adjustment parameter.

[0076] The water bath 3 is a component of the reactor, which is used to control the temperature of the reactor body through water circulation or other media. The data recording module will first evaluate the temperature control effect of the water bath 3, which usually involves considerations of the temperature stability and uniformity of the water bath 3.

[0077] Based on these evaluation results, the data recording module generates a first temperature adjustment threshold value, which represents the performance limit or optimal operating range of the water bath 3 in terms of temperature control.

[0078] Afterwards, the data recording module combines the temperature adjustment interval (determined according to the trend change of the by-product) and the two work together to determine the first temperature warning interval. This warning interval means that when the temperature of the water bath 3 approaches or exceeds its performance limit, the data recording module will issue a warning to prompt the operator to make adjustments.

[0079] Similarly, the temperature control tube 2 is another temperature control device inside the reactor. Its principle is similar to that of the water bath 3, but it is aimed at the temperature control of a specific area in the reactor. The data recording module will evaluate the temperature control effect of the temperature control tube 2 and generate a second temperature adjustment threshold. Similarly, combining the temperature adjustment interval and the second temperature adjustment threshold, the data recording module will determine the second temperature warning interval. This warning interval is used to monitor the temperature control effect of the temperature control tube 2 and issue a warning when necessary.

[0080] In addition to considering the temperature control effects of the water bath 3 and the temperature control tube 2 separately, the data recording module also comprehensively considers the overall effect of the two. This is done to ensure that the temperature of different parts in the reactor can be effectively controlled, thereby improving the overall reaction efficiency and quality.

[0081] Based on this comprehensive consideration, the data recording module generates a third temperature adjustment threshold.

[0082] Combining the temperature adjustment interval and the third temperature adjustment threshold, the data recording module determines the third temperature warning interval. This warning interval provides a more comprehensive temperature monitoring solution, which helps to timely discover and deal with possible temperature problems.

[0083] Finally, the data recording module will generate temperature adjustment parameters based on the temperature acquisition data set. These parameters will guide how to adjust the output of the water bath 3 and the temperature control tube 2 according to the real-time temperature conditions, thereby ensuring that the temperature in the kettle is always maintained within the optimal range.

[0084] Through this multi-level, multi-angle temperature monitoring and adjustment solution, the reactor can control the temperature more accurately, improve product quality and production efficiency, while reducing energy consumption and production costs.

[0085] In order to achieve a positive correlation between the homogenization of the material body and the homogenization of the temperature by the temperature control tube 2, in this embodiment, a power cylinder 9 is fixed to the side of the kettle body 1, and a stator is provided on the inner wall of the power cylinder 9. A rotor 10 is fixed to the end of the liquid inlet pipe 5, and the rotor 10 and the stator are arranged in a gap rotation fit, and a liquid inlet is also provided on the side of the liquid inlet pipe 5;

[0086] The water bath 3 is also provided with a water pump 12 for supplying liquid to the power cylinder 9 .

[0087] When the water pump 12 is started, water is continuously injected into the power cylinder 9. Here, the water not only plays a role in transferring heat, but also is the key power to promote the operation of the entire temperature control tube 2.

[0088] Specifically, when the water passes through the gap between the rotor 10 and the stator, the impact force of the water flow drives the rotor to rotate. As the rotor rotates, the temperature control tube 2 connected thereto also begins to rotate slowly. This rotation not only enhances the heat exchange efficiency between the temperature control tube 2 and the material, but also plays a stirring role, further promoting the homogenization of the material. It is worth mentioning that as the flow rate of the water increases, the temperature control effect will also be significantly improved. This is because a faster flow rate means a higher heat exchange efficiency, which makes the temperature of the material more homogenous.

[0089] In addition, the increase in water flow rate will directly increase the rotation speed of the temperature control tube 2. This increase in rotation speed further enhances the homogenization of the material and ensures the efficient conduct of the chemical reaction. Finally, the water that has completed the heat exchange is discharged through the liquid outlet pipe 4 and smoothly flows back to the water bath 3, thus forming a closed circulation system.

[0090] This method of using flowing water to achieve temperature control is not only effective, but also highly practical and flexible. By accurately controlling the power of the water pump and the flow rate of the water flow, the temperature distribution in the temperature control tube 2 and the degree of material homogenization can be easily adjusted.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
