At the same time, when the sealing cover 203 is covered, the control cover 205 can be pushed and pressed against the end face of the connecting pipe 201 under the action of the elastic force of the spring 207 itself. At this time, the sealing rubber ring 206 will be squeezed and deformed, thereby ensuring the sealing here, and the operation is simple and easy to use.

[0028] See also Figure 1 and Figure 3As shown, a hindered phenol antioxidant reactor, a temperature control component 3, includes a temperature sensor 301, a processor 302, a telescopic shell 303, a telescopic inner core 304, a power supply 305, a rotating piece 306, and a control power supply 307. The temperature control component 3 is convenient for controlling the temperature of the reaction between the material and the hindered phenol antioxidant so that it is within a suitable range. The telescopic inner core 304 forms a sliding structure with the rotating piece 306 through the telescopic shell 303, and the rotating piece 306 forms a rotating structure with the power supply 305 and the control power supply 307; the temperature sensor 301 can sense the temperature change in the reactor body 1 and transmit it in the form of an electrical signal, so that the operation of the heating tube 308 can be controlled. At the same time, when the temperature is too high, the circuit of the heating tube 308 can be disconnected, so as to ensure that the temperature of the reaction between the material and the antioxidant inside the reactor body 1 is within a suitable range, so that the reaction effect is better.

[0029] See also Figure 1 , Figure 4 and Figure 5 As shown, a hindered phenol antioxidant reactor, a reaction mixing component 4, includes a motor 401, a first gear 402, a control rod 403, a second gear 404, a support seat 405, a cover plate 406, a fixed seat 407, and a ball 408. The reaction mixing component 4 can make the material and the hindered phenol antioxidant be fully mixed, thereby increasing the practicality of the device. The reactor body 1 forms a rotating structure through the second gear 404, the support seat 405 and the fixed seat 407, and the second gear 404 and the control rod 403 are meshed with each other, and the control rod 403 and the first gear 402 are meshed with each other. The ball 408 forms a rotating structure through the cover plate 406 and the fixed seat 407, and the ball 408 is arranged at the same angle with respect to the inside of the fixed seat 407; through the operation of the motor 401 and the transmission of the gear, the reactor body 1 can be driven to rotate, so that the material and the antioxidant inside can be evenly mixed, so that the material can fully react, thereby increasing the practicality of the device.

[0030] Working principle: First, add materials and hindered phenol antioxidants to the reactor body 1, sense its internal temperature through the temperature sensor 301, and transmit the signal to the processor 302. By setting a program for the processor 302, when the internal temperature of the reactor body 1 is too low, the processor 302 will transmit it to the telescopic shell 303 in the form of an electrical signal, so that the telescopic inner core 304 extends and pushes the rotating piece 306 to rotate around the power supply 305 and finally touches the control power supply 307. There is an electrical connection between the control power supply 307 and the heating tube 308. At the same time, the power supply 305 can provide electrical energy. At this time, the circuit of the heating tube 308 is connected, so that the inside of the reactor body 1 is heated. When the temperature rises to a certain level, the temperature sensor 301 senses the temperature and transmits it to the processor 302, and the processor 302 controls the telescopic shell 303 in the form of an electrical signal, so that the telescopic inner core 304 retracts into the telescopic shell 303. At this time, the rotating piece 306 automatically Under the action of body gravity, it rotates again, thereby deviating from the control power supply 307, and the circuit of the heating tube 308 can be disconnected, so that the temperature inside the reactor body 1 is within a suitable range. Then, during the reaction process, the motor 401 switch is turned on, and the operation of the motor 401 drives the first gear 402 to rotate. When the first gear 402 is engaged with one end of the control rod 403, the control rod 403 can be moved to one side, and when the first gear 402 is engaged with the other end of the control rod 403, the control rod 403 can be moved to the other side. The control rod 403 is engaged with the second gear 404. The process of the control rod 403 sliding left and right will drive the second gear 404 to rotate left and right, so that the reactor body 1 can be rotated, and then the material inside it and the hindered phenol antioxidant are evenly mixed. At the same time, during the rotation of the support seat 405, the cover plate 406 presses the ball 408 to rotate, and the rotation of the ball 408 will also make the support seat 405 rotate more smoothly;

[0031] Next, when it is necessary to take samples in the reactor body 1 to check the reaction degree of the material during the reaction process, press down and rotate the sealing cover 203. At this time, the control cover 205 squeezes the spring 207 upward, and the protrusion 204 can be detached from the slot 202. At this time, the sealing cover 203 can be disassembled, and samples can be taken from the reactor body 1 through the connecting tube 201. When the sampling is completed, align the protrusion 204 with the slot 202, and press down again and rotate the sealing cover 203. At this time, the connecting tube 201 will press against the sealing rubber ring 206 on the control cover 205. After the sealing cover 203 is installed, the sealing rubber ring 206 will be squeezed and deformed to ensure the sealing here.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
