[0032] ​​The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is merely meant to provide a better understanding of the subject matter described herein and that modifications and changes can be made to the function and arrangement of elements without departing from the scope of the disclosure. Various examples can omit, substitute, or add various procedures or components as appropriate. Also, features described with respect to some examples can be combined in other examples.

[0033] The invention provides a temperature-controllable glass-lined reactor as shown in the drawings, comprising: Figures 1 to 8

[0034] The reactor 11 and the multi-separation structure 24 separate the interior of the reactor 11 into multiple partitions, and the separation structure 24 is arranged in a switchable structure, so that the interior of the reactor 11 can be switched between a single whole area and multiple partitions, and the multi-separation structure 24 is arranged in a substantially horizontal direction.

[0035] The inner wall of the reactor 11 is provided with a spiral pipe 21, and the interior of the reactor 11 is provided with a temperature adjusting structure 22 in multiple partitions, and the temperature adjusting structure 22 and the spiral pipe 21 are used for common operation to understand the temperature of the material in the interior of the reactor 11, and the temperature adjusting structure 22 is arranged in a stepless switch adjustment; when the separation structure 24 is switched to a closed state, the multiple temperature adjusting structures 22 start to operate.

[0036] Working principle: dynamic partition switching, the multi-separation structure 24 is arranged in a horizontal direction, and through the switchable characteristics, the interior of the reactor 11 can be flexibly converted between a single whole area and multiple independent partitions. Two-stage temperature control linkage: basic temperature adjustment, the inner wall spiral pipe 21 provides basic temperature adjustment. Precise partition temperature control, when the separation structure 24 is closed, the temperature adjusting structures 22 in each partition are started synchronously and work cooperatively with the spiral pipe 21; the temperature adjusting structure 22 is a stepless switch adjustment electric control pipe, realizing independent control of the partition temperature.

[0037] On-demand temperature control: for different materials or reaction stages, through switching the partition state, matching single temperature control or composite temperature control, the spiral pipe 21 cooperates with the partition temperature adjusting structure 22 to meet the differentiated temperature requirements. Avoid local temperature difference: after the partition is closed, each temperature adjusting structure 22 operates independently and can accurately adjust the temperature in the partition, solving the problem of local overheating or uneven cooling caused by the traditional single spiral pipe 21. Efficient operation: the closure of the separation structure 24 directly triggers the start of the temperature adjusting structure 22, realizing the automatic linkage of the partition and temperature control functions, reducing manual intervention.

[0038] ​The reaction kettle 11 is based on the joint operation of the partition structure 24 and the temperature adjusting structure 22. Generally, the reaction kettle 11 is only provided with the spiral pipeline 21 to heat the materials in the reaction kettle 11. However, in the demand of chemical production, the reaction kettle 11 needs to be partitioned and temperature-controlled. The partition mode provided by the application is basically along the horizontal direction, but some variations can also be made to change the volume of different partitions. The switching of the partition structure 24 is linked with the operation of the temperature adjusting structure 22. The temperature adjusting structure 22 starts to operate only when the partition structure 24 is switched to the closed state, that is, the temperature adjusting mode is switched from the single temperature adjusting mode through the spiral pipeline 21 to the temperature adjusting mode through the joint operation of the spiral pipeline 21 and the temperature adjusting structure 22.

[0039] Specifically, the linkage between the switching of the partition structure 24 and the temperature adjusting structure 22 is as follows: the partition structure 24 is specifically an iris mechanism, the temperature adjusting structure 22 is an electrically controlled temperature adjusting pipe, and a controller for synchronously driving the partition structure 24 and the temperature adjusting structure 22 is further included. Workers can realize the synchronous linkage control of the two through the controller.

[0040] The reasons for partitioning and temperature-controlling the reaction kettle 11 in the demand of 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.

[0041] As shown in Figure 2 and Figure 7 , the temperature adjusting structure 22 is an electrically controlled temperature adjusting pipe that matches the shape of the spiral pipeline 21. The temperature adjusting structure 22 is used to adjust the temperature of the materials in the reaction kettle 11 and the temperature of the spiral pipeline 21. The spiral pipeline 21 is a cold and hot medium circulating pipeline. The inner side of the spiral pipeline 21 is provided with an assembly groove 28. Multiple partition temperature adjusting structures 22 are embedded and installed on the spiral pipeline 21 through the assembly groove 28. The spiral pipeline 21 and the temperature adjusting structure 22 jointly adjust the temperature of the materials in the partitions of the reaction kettle 11.

[0042] As shown in Figure 2 and Figure 8 , the partition structure 24 is an iris mechanism. The iris mechanism includes a driving push rod 29 and multiple groups of iris partition plates 210 that can be jointly adjusted. The driving push rod 29 is used to drive the opening and closing operation of the iris mechanism. The iris mechanism is provided with multiple groups. The multiple groups of iris mechanisms can be adjusted simultaneously or separately, so that there are multiple different partition modes based on the partition of the reaction kettle 11 by the multiple groups of partition structures 24.

[0043] As shown in Figure 2 and Figure 5As 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.

[0044] like Figure 4 and Figure 6 As 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] In summary, the present invention also has the following comprehensive effects:

[0050] Partition switching mechanism: The multi-component separation structure 24 uses an iris mechanism to divide the interior of the reaction kettle 11 into multiple independent partitions in the horizontal direction. This structure can be switched on and off, and through synchronous driving by the controller, the interior of the reaction kettle 11 can be flexibly converted between "overall area" and "multiple partitions". When the separation structure 24 is switched to the closed state, the temperature adjustment structure 22 automatically starts to operate; conversely, when the separation structure 24 is opened, the temperature adjustment structure 22 stops, and only the spiral pipe 21 works.

[0051] Temperature adjustment mechanism: The spiral pipe 21 serves as the cold and hot medium circulation pipe 26 and is responsible for basic temperature adjustment. The temperature adjustment structure 22 is an electrically controlled temperature adjustment pipe that can be adjusted steplessly and is embedded in the inside of the spiral pipe 21 through the assembly groove 28 and works together with the spiral pipe 21. When the partitions are formed, the temperature adjustment structure 22 independently adjusts the material temperature for each partition. The temperature sensor 16 is arranged in the vertical direction and passes through the clearance hole of the separation structure 24 to monitor the temperature of each partition in real time and provide feedback for the controller.

[0052] Auxiliary operation mechanism: The stirring paddle 13 is isolated from the iris mechanism through the rotating bearing 27 to avoid the influence of the locking of the separation plate on stirring. The circulation pipe 26 and the circulation pump 211 are located above the separation structure 24 to generate radial circulation turbulence, and the outlet end is designed in a flat shape to enhance the turbulence, and the effects include: being staggered with the direction of the stirring paddle 13 to improve stirring uniformity and heating effect. When the separation structure 24 is opened, it prevents crystallization or solid suspension from depositing on the iris surface and promotes uniform movement of the material.

[0053] Optimized reaction conditions: Through partition temperature control, different materials and chemical reaction characteristics are adapted to avoid local overheating or uneven cooling, improve reaction stability and controllability. Improve reaction efficiency: Prevent side reactions caused by temperature fluctuations, improve reaction selectivity and yield, for example, for special process requirements such as crystallization, precise temperature control is achieved. Energy saving and consumption reduction: The temperature adjustment structure 22 only works when the partitions are closed and works together with the spiral pipe 21 to reduce unnecessary energy consumption; at the same time, the switchable partition mode allows resources to be allocated on demand to reduce overall operating costs. Enhance mixing and prevent deposition: The turbulence generated by the circulation pipe 26 cooperates with the stirring paddle 13 to improve material mixing uniformity and improve heating or cooling efficiency; at the same time, the turbulence prevents solid particles from depositing on the inner wall of the reaction kettle 11 or the iris surface, reducing cleaning and maintenance requirements. Operational flexibility and reliability: The iris mechanism can be adjusted simultaneously or separately to achieve multiple partition modes to meet diverse production needs; the rotating bearing 27 and temperature sensor 16 design ensures that stirring and monitoring are not disturbed, improving equipment reliability and lifespan. Through the linkage of the separation structure 24, the temperature adjustment structure 22, and the auxiliary components, the invention realizes the partition temperature control switching of the reaction kettle 11, and the core advantage lies in optimizing the chemical reaction process, saving energy and being efficient, and solving the problems of uneven temperature and solid deposition.

[0054] The above describes the embodiments of the present application, but the present application is not limited to the above-described specific embodiments, and the above-described specific embodiments are only illustrative but not restrictive, and those skilled in the art can make many forms under the inspiration of the present application, which all belong to the protection of the present application.
