[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0020] The invention provides Figures 1 to 8 As shown, a zoned temperature-controlled glass-lined reactor comprises: The reactor 11 and multiple sets of partition structures 24, which divide the interior of the reactor 11 into multiple partitions. The partition structures 24 are configured to be openable and closable, so that the interior of the reactor 11 can be switched between an overall area and multiple partitions. The multiple sets of partition structures 24 are arranged in a generally horizontal direction; A spiral pipe 21 is provided on the inner wall of the reactor 11, and temperature control structures 22 are provided in multiple partitions inside the reactor 11. The temperature control structure 22 and the spiral pipe 21 are used to work together to understand the temperature of the material inside the reactor 11. The temperature control structure 22 is configured to be steplessly adjustable; when the partition structure 24 is switched to a closed state, multiple temperature control structures 22 start to operate.

[0021] Working Principle: Dynamically switch between zones. Multiple horizontally arranged partition structures 24, through their switchable nature, allow the reactor 11 to flexibly transition between a single, integrated area and multiple independent zones. Two-stage temperature control linkage: The spiral pipes 21 on the inner wall provide basic temperature regulation. For precise zone temperature control, when the partition structures 24 close, the temperature control structures 22 within each zone are activated synchronously, operating in conjunction with the spiral pipes 21. The temperature control structures 22 are electrically controlled, with stepless switching, to achieve independent temperature control for each zone.

[0022] On-demand temperature control: By switching partitions to match single or combined temperature control for different materials or reaction stages, the spiral pipe 21, in conjunction with the zoned temperature control structure 22, meets differentiated temperature requirements. Avoiding localized temperature differences: After the partitions are closed, each temperature control structure 22 operates independently to precisely adjust the temperature within the zone, eliminating the localized overheating or uneven cooling problems caused by traditional single spiral pipes 21. Highly efficient operation: Closing the partition structure 24 directly activates the temperature control structure 22, automatically linking the zoning and temperature control functions and reducing manual intervention.

[0023] The reactor 11 is based on the joint operation of the partition structure 24 and the temperature control structure 22. The conventional reactor 11 is generally only provided with a spiral pipe 21 to heat the material inside the reactor 11. However, for different materials and different chemical reaction characteristics, the temperature inside the reactor 11 needs to be zoned and controlled under the needs of chemical production. The partitioning method provided by the invention of the present application is basically in the horizontal direction, but it can also be deformed to change the volume size between different partitions; the switching of the partition structure 24 is linked to the operation of the temperature control structure 22. The temperature control structure 22 starts to operate when the partition structure 24 is switched to a closed state, that is, it switches from the conventional single temperature control method of the spiral pipe 21 to the temperature control method of the spiral pipe 21 and the temperature control structure 22 working together.

[0024] Specifically, regarding the specific implementation method of the switching of the partition structure 24 and the linkage of the temperature control structure 22: the partition structure 24 is specifically an iris mechanism, and the temperature control structure 22 is set as an electrically controlled temperature control tube, and also includes a controller for synchronously driving the partition structure 24 and the temperature control structure 22. The staff can achieve synchronous linkage control of the two through the controller.

[0025] The reasons for performing zoned temperature control inside the reactor 11 in chemical production include but are not limited to: optimizing reaction conditions, preventing local overheating or uneven cooling, improving reaction selectivity and yield, meeting special process requirements such as crystallization, or saving energy and reducing consumption.

[0026] like Figure 2 and Figure 7 As shown, the temperature control structure 22 is configured as an electrically controlled temperature control tube that fits the shape of the spiral pipe 21. The temperature control structure 22 is used to adjust the temperature of the material inside the reactor 11 and the temperature of the spiral pipe 21. The spiral pipe 21 is configured as a cold and hot medium circulation pipe. The inner side of the spiral pipe 21 is provided with an assembly groove 28. Multiple partitioned temperature control structures 22 are embedded and installed on the spiral pipe 21 through the assembly groove 28. The spiral pipe 21 and the temperature control structure 22 jointly regulate the temperature of the material in the partitions inside the reactor 11.

[0027] like Figure 2 and Figure 8 As shown, the partition structure 24 is configured as an iris mechanism, which includes a driving push rod 29 and multiple groups of iris partition plates 210 that can be adjusted together. The driving push rod 29 is used to drive the opening and closing operations of the iris mechanism. Multiple groups of iris mechanisms are provided, and the multiple groups of iris mechanisms can be adjusted simultaneously or separately, so that there are multiple different partitioning methods for the partitioning of the interior of the reactor 11 based on the multiple groups of partition structures 24.

[0028] like Figure 2 and Figure 5 As shown, a stirring paddle 13 is provided inside the reactor 11, and a rotating bearing 27 is provided on the paddle shaft of the stirring paddle 13 at a position corresponding to the iris mechanism. The setting of the rotating bearing 27 can prevent multiple sets of iris partition plates 210 from being locked to the paddle shaft of the stirring paddle 13, thereby affecting the rotation of the stirring paddle 13.

[0029] like Figure 4 and Figure 6As shown, a circulation pipe 26 and a circulation pump 211 are provided on the inner wall of the reactor 11 above the partition structure 24. The circulation pipe 26 is used to provide radial circulation turbulence inside the reactor 11. The circulation turbulence has two functions. First, it is staggered with the direction of the stirring paddle 13 to obtain better stirring effect and uniform heating effect; second, when crystallization is produced by the reaction inside the partition of the reactor 11, even if the partition structure 24 is in an open state, the crystals will fall on the surface of the iris mechanism. The turbulence provided by the circulation pipe 26 can make the crystals or other solid suspensions move more freely and evenly inside the reactor 11, rather than always on the inner wall of the reactor 11.

[0030] Specifically, the shape of the circulation pipe 26 is as follows Figure 6 As shown, one end is tubular and the other end is flat, and the flat end is the liquid outlet end. This shape setting can make the turbulence generated by the circulation pipe 26 greater. The circulation pipe 26 can also be set into multiple groups and distributed in a circular array on the inner wall of the reactor 11.

[0031] like Figure 2 As shown, multiple groups of temperature sensors 16 are vertically arranged inside the reactor 11 , and holes for accommodating the temperature sensors 16 are provided on the partition structure 24 . The multiple groups of temperature sensors 16 are used to detect the temperatures of multiple partitions in real time.

[0032] like Figure 1 、 Figure 2 and Figure 8 As shown, a mounting bracket 23 is provided inside the reactor 11, and the spiral pipe 21 is installed inside the reactor 11 through the mounting bracket 23. A liquid inlet pipe 14 and a liquid outlet pipe 15 are respectively provided at both ends of the spiral pipe 21. The liquid inlet pipe 14 and the liquid outlet pipe 15 are used for the circulation of external cold and hot media.

[0033] The reactor 11 is provided with a mounting ring 25 on its inner wall, and the partition structure 24 is mounted on the reactor 11 via the mounting ring 25. The reactor 11 is provided with a glass-lined lining 12, and the reactor 11 is provided with a feed port 17 and a discharge port.

[0034] In summary, the present invention also has the following comprehensive effects: Partition Switching Mechanism: Multiple partitions 24 utilize an iris mechanism to horizontally divide the interior of the reactor 11 into multiple independent zones. This structure can be switched on and off, synchronously driven by a controller, allowing the reactor 11 to flexibly switch between a "whole area" and "multiple zones." When the partitions 24 are closed, the temperature control mechanism 22 automatically begins operating. Conversely, when the partitions 24 are open, the temperature control mechanism 22 ceases operation, leaving only the spiral pipe 21 in operation.

[0035] Temperature Regulation Mechanism: Spiral pipe 21 serves as a cooling and heating medium circulation pipe 26, responsible for basic temperature regulation. The thermostat 22 is an electrically controlled thermostat with stepless on / off adjustment. It is embedded within spiral pipe 21 via mounting slot 28 and operates in conjunction with spiral pipe 21. When partitions are formed, thermostat 22 independently regulates the material temperature for each partition. A temperature sensor 16 is positioned vertically, passing through a clearance hole in the partition structure 24, to monitor the temperature of each partition in real time and provide feedback to the controller.

[0036] Auxiliary Operation Mechanism: The agitator paddle 13 is isolated from the iris mechanism by a rotating bearing 27, preventing the partition plate from locking and affecting agitation. A circulation pipe 26 and a circulation pump 211 are located above the partition structure 24, generating radial turbulent flow. The flattened outlet design enhances turbulence, intersecting the direction of the agitator paddle 13 to improve agitation uniformity and heating efficiency. When the partition structure 24 is open, it prevents crystallization or suspended solids from settling on the iris surface, promoting uniform material movement.

[0037] Optimize Reaction Conditions: Zoned temperature control adapts to different materials and chemical reaction characteristics, avoiding local overheating or uneven cooling, and improving reaction stability and controllability. Improve Reaction Efficiency: Prevent side reactions caused by temperature fluctuations, improve reaction selectivity and yield, and achieve precise temperature control for specialized processes such as crystallization. Energy Saving and Cost Reduction: The temperature control mechanism 22 operates only when zones are closed, working in conjunction with the spiral pipe 21 to reduce unnecessary energy consumption. Furthermore, the switchable zone configuration allows for on-demand resource allocation, reducing overall operating costs. Enhanced Mixing and Anti-Deposition: The turbulent flow generated by the circulation pipe 26 works in conjunction with the agitator 13 to improve material mixing uniformity and enhance heating or cooling efficiency. Furthermore, this turbulent flow prevents solid particles from depositing on the inner wall of the reactor 11 or on the iris surface, reducing cleaning and maintenance requirements. Operational Flexibility and Reliability: The iris mechanism can be adjusted simultaneously or individually, enabling multiple zone configurations to meet diverse production needs. The rotating bearing 27 and temperature sensor 16 ensure uninterrupted mixing and monitoring, improving equipment reliability and lifespan. This invention realizes the zoned temperature control switching of the reactor 11 through the linkage of the partition structure 24, the temperature adjustment structure 22 and the auxiliary components. The core advantage lies in optimizing the chemical reaction process, saving energy and efficiency, and solving the problems of uneven temperature and solid deposition.

[0038] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
