The system employs a combination of multiple temperature sensors and cooling devices. The sensors are distributed at different heights within the vessel, and the cooling devices are configured to correspond to the sensors. Targeted cooling is achieved through a ring-shaped stirrer and a heat-conducting ring tube, combined with a controller to realize automatic control.
It improves the accuracy and uniformity of temperature detection inside the reactor, enabling efficient and targeted reduction of temperature in overheated areas, reducing the risk of coking, and enhancing production stability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for preventing coking in resin reactions, and more specifically to an intelligent temperature control device for preventing coking in resin reactors. Background Technology
[0002] Coking occurs in resin reactors during production, generally due to the following reasons:
[0003] Improper temperature control: If the temperature inside the reactor is too high, exceeding the decomposition temperature of the material or the optimal temperature range for the polymerization reaction, it may lead to local overheating of the material and carbonization or coking.
[0004] Uneven mixing: If the mixing effect is poor, it is easy to cause excessively high local concentration or uneven temperature distribution, which will lead to overheating and coking of the material in some areas.
[0005] The existing resin reaction treatment, as shown in application number CN201620029784.5, "A high-efficiency unsaturated resin reactor stirrer", uses a temperature sensor to detect the temperature inside the reactor so as to adjust it in time and reduce the possibility of coking.
[0006] The stirring in a reaction vessel is generally carried out in a vertical, circular motion. However, uneven temperature distribution inside the vessel is usually localized and occurs in unpredictable locations. Therefore, when localized overheating occurs inside the vessel, there is a disadvantage of inconvenient adjustment and operation. Utility Model Content
[0007] The purpose of this utility model is to provide an intelligent temperature control and anti-coking device for resin reactors in order to solve the above-mentioned technical problems.
[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0009] This utility model proposes an intelligent temperature control and anti-coking device for a resin reactor, comprising:
[0010] The vessel body and the temperature sensor installed on it, and the mixing mechanism that stirs the inside of the vessel body are installed on the vessel body.
[0011] The temperature sensor is provided in multiple groups and is distributed on the same vertical plane from top to bottom;
[0012] It also includes a cooling device fixed to the outside of the vessel;
[0013] The cooling device is equipped with multiple sets of cooling devices, each corresponding to a set of temperature sensors on the same horizontal plane. The multiple sets of temperature sensors and cooling devices are distributed on opposite sides of the vessel body.
[0014] As a preferred embodiment of this utility model, the cooling device includes:
[0015] A heat-conducting ring tube is attached and fixed to the outside of the vessel body;
[0016] A liquid inlet pipe, one end of which is fixedly connected to one end of a heat-conducting ring pipe;
[0017] The liquid outlet pipe has one end connected and fixed to the other end of the heat-conducting ring pipe.
[0018] As a preferred embodiment of this utility model, the method further includes a switching valve;
[0019] The cooling devices are equipped with multiple sets of liquid inlet pipes and liquid outlet pipes. The multiple sets of liquid inlet pipes are connected and fixed together, and the multiple sets of liquid outlet pipes are connected and fixed together.
[0020] Each group's inlet and outlet pipes are connected to a fixed switch valve.
[0021] As a preferred embodiment of this utility model, a controller is installed on the outside of the vessel body.
[0022] The beneficial effects of this utility model are as follows:
[0023] By setting multiple sets of temperature sensors to detect resin at different heights inside the reactor, the detection range is increased to improve overall accuracy. Under the action of the mixing mechanism, the resin is agitated in a circular motion to transfer the cooling provided by the cooling device in a circular motion, which can provide targeted cooling treatment for overheated areas. At the same time, the cooling device is far away from the temperature sensors, so it is not easy to interfere with the temperature sensor detection when the cooling process is generated, thus ensuring high accuracy.

[0024] Figure 1 This is a schematic diagram of the structure of this utility model.
[0025] Reference numerals: vessel body-1, temperature sensor-2, cooling device-3, switch valve-4, heat conduction ring pipe-31, liquid inlet pipe-32, liquid outlet pipe-33. Detailed Implementation Example 1:
[0026] like Figure 1 As shown in this embodiment, a smart temperature control and anti-coking device for a resin reactor is proposed, comprising:
[0027] The vessel body 1 and the temperature sensor 2 installed on it; a mixing mechanism for stirring the vessel body 1 around it is installed on the vessel body 1.
[0028] The temperature sensor 2 is provided in multiple sets and is distributed on the same vertical plane from top to bottom; multiple sets of temperature sensors 2 are distributed sequentially from top to bottom on the left end of the vessel body 1, which can detect resin at different height positions inside the vessel body 1, improve the detection range and increase the overall accuracy.
[0029] It also includes a cooling device 3 fixed outside the vessel body 1; the vessel body 1 is made of a heat-conducting material (such as stainless steel) to cool the inside of the vessel body 1.
[0030] The cooling device 3 is equipped with multiple sets of cooling devices 3, each corresponding to a set of temperature sensors 2 on the same horizontal plane. The multiple sets of temperature sensors 2 and cooling devices 3 are distributed on opposite sides of the vessel body 1. Multiple sets of cooling devices 3 are installed horizontally from top to bottom at the right end of the vessel body 1, corresponding to a set of temperature sensors 2. In this way, the resin in the vessel body 1 can be stirred in a circular motion under the action of the mixing mechanism, so that the cooling provided by the cooling device 3 can be transferred in a circular motion. This allows for targeted cooling of overheated areas. At the same time, the cooling device 3 is far away from the temperature sensor 2, so it is less likely to interfere with the detection of the temperature sensor 2 when cooling is performed, thus ensuring high accuracy.
[0031] The specific structure of the cooling device 3 is shown below:
[0032] Cooling device 3 includes;
[0033] A heat-conducting ring tube 31 is attached and fixed to the outside of the vessel body 1; the heat-conducting ring tube 31 is made of stainless steel and has a connected inlet and outlet end;
[0034] The liquid inlet pipe 32 is connected and fixed at one end to the heat-conducting ring pipe 31. The liquid inlet pipe 32 is made of stainless steel. The left end of the liquid inlet pipe 32 is connected and fixed to the inlet end of the heat-conducting ring pipe 31, and the right end of the liquid inlet pipe 32 is connected and fixed to an external liquid extraction position (the liquid is water or silicone oil). A pump is installed between the liquid inlet pipes 32 to provide power to extract the cooling liquid.
[0035] The liquid outlet pipe 33 has one end connected and fixed to the other end of the heat-conducting ring pipe 31. The liquid outlet pipe 33 is made of stainless steel. The left end of the liquid outlet pipe 33 is connected and fixed to the outlet end of the heat-conducting ring pipe 31. The right end of the liquid outlet pipe 33 is connected to an external liquid collection position for backflow.
[0036] The outer side of the vessel body 1 is equipped with a controller; the controller is a PLC controller and is connected to an external power source to connect to and supply power to the electrical components and equipment and control their use. Example 2:
[0037] like Figure 1As shown, its difference from Embodiment 1 is that it also includes a switching valve 4, which can be an electric or pneumatic valve (such as a butterfly valve with adjustable flow rate) to facilitate control of opening and closing.
[0038] The multiple cooling devices 3 are each provided with multiple sets of liquid inlet pipes 32 and liquid outlet pipes 33. The multiple sets of liquid inlet pipes 32 are connected and fixed together, and the multiple sets of liquid outlet pipes 33 are connected and fixed together. As shown in the figure, each set of the multiple cooling devices 3 has the same structure, that is, multiple sets of liquid inlet pipes 32 and liquid outlet pipes 33 are also provided. After the liquid enters, one set of liquid inlet pipes 32 or liquid outlet pipes 33 can flow freely within the set.
[0039] Each group's inlet pipe 32 and outlet pipe 33 are respectively connected to a fixed switch valve 4; according to the above, only one liquid passage and drainage component needs to be set to simplify the overall structure (as shown in the figure, when the cooling device 3 of the top group is used, the leftmost switch valve 4 can be opened).
[0040] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
