Its core, through a built-in dynamic temperature-regulating structure, precisely controls the temperature parameters during the reaction process. This allows for rapid response to temperature fluctuations caused by exothermic or endothermic reactions, maintaining the reaction system stable within the optimal temperature range. Furthermore, it dynamically adjusts the temperature control intensity according to the temperature requirements of different reaction stages.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A temperature-controlled reactor for the synthesis of aminohexanonitrile based on a dynamic temperature-regulating structure includes a reaction device 1, a premixing component 2 bolted to the top of the reaction device 1, and a solenoid valve 3 connected to the bottom of the premixing component 2. The solenoid valve 3 is connected to the top of the reaction device 1.

[0029] The premixing component 2 includes a circular tube 201, a top cover 202 bolted to the top of the circular tube 201, a filling pipe 203 fixedly connected inside the top cover 202, a hollow tube 204 rotatably connected inside the surface of the circular tube 201, a filter screen 205 fixedly connected to the surface of the hollow tube 204, a hollow ring 206 fixedly connected to the surface of the circular tube 201, several spray pipes 207 connected to the side of the hollow ring 206 near the circular tube 201, a water pump 208 connected to the bottom of the hollow ring 206, the water pump 208 fixedly connected to the rear side of the circular tube 201, an outer pipe 209 connected to the top of the water pump 208, a cavity 210 opened at the bottom of the top cover 202, and the hollow tube 204 communicating with the interior of the cavity 210.

[0030] In this embodiment: The reaction device 1, the core site of the aminohexanonitrile synthesis reaction, provides the reaction space. The premixing component 2 premixes the materials before the reaction, shortening the subsequent reaction time. The solenoid valve 3 controls the material flow between the premixing component 2 and the reaction device 1, achieving precise feeding. The circular tube 201, the main cavity for premixing, carries the material mixing process. The top cover 202 seals the top of the circular tube 201, preventing material leakage during mixing. Simultaneously, the cavity 210 at its bottom is filled with liquid. The guide provides a channel and also fixes the filling pipe 203. By setting the filling pipe 203, it is connected to the delivery pipe of one of the liquids, which is the dedicated channel for the liquid to enter the premixing component 2. The liquid is introduced into the cavity 210 at the bottom of the top cover 202. By setting the hollow tube 204, it receives the first liquid flowing in from the cavity 210. On the other hand, as it rotates with the drive structure, the liquid in the tube is thrown out through the filter screen 205 by centrifugal force. At the same time, it provides an installation base for the overall stirring structure. By setting the filter screen 205, it is attached to the surface of the hollow tube 204. When the hollow tube 204... 4. During rotation, the first liquid flowing through the filter removes impurities, and the auxiliary liquid is smoothly thrown out of the hollow tube 204 by centrifugal force, achieving liquid dispersion. A hollow ring 206 is set as a diversion structure for the second liquid, receiving the liquid delivered from the water pump 208 and evenly distributing it to each spray pipe 207. By setting the spray pipes 207 and connecting them to the hollow ring 206, the second liquid is evenly sprayed into the circular tube 201 in a spraying manner, fully contacting and mixing with the first liquid thrown out by centrifugation. The water pump 208 is then used to further disperse the second liquid. The first liquid is powered by an external pipe 209, which draws in a second liquid from the outside, pressurizes it, and delivers it to a hollow ring 206. The external pipe 209 connects to a storage device for the second liquid, which is the channel for the liquid to enter the premixing component 2. The liquid is then delivered to a water pump 208. A cavity 210 is provided at the bottom of the top cover 202. One end of the cavity is connected to the filling pipe 203 to receive the first liquid, and the other end is connected to the hollow tube 204. This cavity provides a transition space for the first liquid to flow from the filling pipe 203 to the hollow tube 204, ensuring smooth liquid flow.

[0031] Specifically, such as Figure 3 As shown, a drive motor 4 is bolted to the bottom of the round tube 201, and the drive motor 4 is fixedly connected to the bottom of the hollow tube 204.

[0032] Specifically, such as Figure 3 As shown, a stirring rack 5 is fixedly connected to the surface of the hollow tube 204, and a scraper 6 is fixedly connected to the side of the stirring rack 5 away from the hollow tube 204.

[0033] Specifically, such as Figure 3 As shown, a frame 7 is fixedly connected to the surface of the hollow tube 204, and a protective net 8 is fixedly connected to the inside of the frame 7.

[0034] In this embodiment: A drive motor 4 provides power for the rotation of the hollow tube 204, driving it to rotate stably and ensuring that the first liquid can be smoothly ejected from the filter screen 205 by centrifugal force. Simultaneously, it drives the stirring frame 5, scraper 6, and other structures. The stirring frame 5, fixed to the surface of the hollow tube 204, rotates synchronously with the hollow tube 204, stirring the two liquids mixing inside the circular tube 201 to further break up liquid agglomeration and improve mixing uniformity. The scraper 6, with one end fixed to the stirring frame 5 and the other end attached to the inner wall of the circular tube 201, scrapes off liquid material adhering to the inner wall of the circular tube 201 as it rotates with the stirring frame 5, avoiding material waste and preventing residual material from affecting subsequent mixing effects. A frame 7, serving as a support carrier for the protective net 8, is fixed to the surface of the hollow tube 204, providing a stable installation base for the protective net 8 and ensuring its fixed position. The protective net 8 filters the mixed liquid and improves mixing efficiency.

[0035] Specifically, such as Figure 3 As shown, two circular plates 9 are fixedly connected inside the circular tube 201, and holes 10 are opened on the surface of both circular plates 9.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the bottoms of the two circular plates 9 are connected to conical hollow sleeves 11, and the material of the conical hollow sleeves 11 is stainless steel.

[0037] In this embodiment: by setting a circular plate 9 and holes 10, the holes 10 on the surface of the circular plate 9 can slow down the flow rate of the filtered mixture and improve the mixing effect. The conical hollow sleeve 11 is also an auxiliary structure to slow down the flow of the mixture.

[0038] Specifically, such as Figure 4As shown, heating rings 12 are fixedly connected inside both circular plates 9, and the two circular plates 9 are fixedly connected to the surface of the hollow tube 204.

[0039] Specifically, such as Figure 5 As shown, a sealing ring 13 is fixedly connected to the bottom of the top cover 202, and a sealing groove 14 that cooperates with the sealing ring 13 is opened on the top of the hollow tube 204.

[0040] In this embodiment: by setting a heating ring 12 embedded inside the circular plate 9, heat is generated after being energized to heat the circular plate 9 and the mixed liquid flowing through the circular plate 9, and the liquid temperature is adjusted to a premixing temperature suitable for the synthesis reaction of aminohexanonitrile, thus laying the foundation for subsequent reactions. By setting a sealing ring 13 and a sealing groove 14, the internal sliding connection of the sealing ring 13 and the sealing groove 14 enhances the sealing performance of the connection between the top cover 202 and the hollow tube 204, and avoids material leakage that affects the mixing efficiency.

[0041] Specifically, such as Figure 1 As shown, several support frames 15 are fixedly connected to the bottom of the reaction device 1, and anti-slip pads 16 are fixedly connected to the bottom of each support frame 15.

[0042] Specifically, such as Figure 2 As shown, a corrosion-resistant sleeve 17 is fixedly connected inside the round tube 201. The corrosion-resistant sleeve 17 is made of stainless steel.

[0043] In this embodiment: By setting a support frame 15 and fixing it to the bottom of the reaction device 1, the entire reactor is supported from below, keeping the equipment in a stable upright state and preventing it from tipping over. By setting an anti-slip pad 16 and attaching it to the bottom of the support frame 15, the friction between the support frame 15 and the ground is increased, preventing the equipment from sliding due to vibration and other factors during operation, further improving the stability of the equipment. By setting a corrosion-resistant sleeve 17 and attaching it to the inner wall of the circular tube 201, the stainless steel material can resist the corrosion of the inner wall of the circular tube 201 by the two liquids and the mixture, protecting the structure of the circular tube 201 and extending the service life of the premixing component 2.

[0044] Working principle: The first liquid is introduced into the bottom cavity 210 of the top cover 202 through the filling pipe 203, and then flows into the hollow tube 204. At the same time, the water pump 208 draws the second liquid through the outer pipe 209 and delivers it to the hollow ring 206. It is then evenly sprayed into the circular tube 201 through multiple spray pipes 207. The drive motor 4 starts to drive the hollow tube 204 to rotate. The first liquid in the hollow tube 204 is first thrown out by the surface filter screen 205 under the action of centrifugal force, achieving preliminary filtration and dispersion. Then it comes into preliminary contact with the second liquid sprayed by the spray pipes 207 and mixes. The mixed liquid then flows to the two perforated circular plates 9 inside the circular tube 201. The flow rate is slowed down by the perforations 10 and the conical hollow sleeve 11 at the bottom of the circular plates 9, which prolongs the contact time and strengthens the liquid. To improve the mixing effect, the heating ring 12 inside the circular plate 9 preheats the mixture to a temperature suitable for the aminohexanonitrile synthesis reaction. After the mixture passes through the circular plate 9, the stirring rack 5, which rotates synchronously with the hollow tube 204, performs a final stirring to further improve the mixing uniformity. The scraper 6 on one side of the stirring rack 5 simultaneously scrapes off the material remaining on the inner wall of the circular tube 201 to avoid waste and contamination. Finally, the solenoid valve 3 is opened, and the material that has undergone premixing, preheating, and final stirring flows precisely into the reaction device 1 to carry out the aminohexanonitrile synthesis reaction. Throughout the process, the support frame 15 and the anti-slip pad 16 ensure stable operation of the equipment, while the sealing ring 13 at the bottom of the top cover 202 and the corrosion-resistant sleeve 17 on the inner wall of the circular tube 201 ensure operational safety and equipment lifespan.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
