[0048] Specifically, a cylinder assembly 104 is provided at the top of the embedded agent tube 103, and the cylinder assembly 104 is connected to the embedded agent tube 103 through a flange. The embedded agent tube 103 includes a buffer shaft tube 1032 and a liquid storage pipe 1033. The buffer shaft tube 1032 is installed above the liquid storage pipe 1033. A switching valve port 1031 is provided on one side of the buffer shaft tube 1032. The switching valve port 1031 is connected to the guide pipe 301. A flow control valve sleeve 1042 is provided below the liquid storage pipe 1033. A float plug 1043 is provided on the inner side of the flow control valve sleeve 1042. A through hole 1044 is provided on the outer surface of the float plug 1043. The liquid storage pipe A liquid storage chamber 1035 is provided inside 1033, a bearing impeller 1034 is provided inside the buffer shaft tube 1032, the bearing impeller 1034 is rotatably connected to the buffer shaft tube 1032, an inner through pipe 1036 is provided at the bottom of the bearing impeller 1034, the catalyst enters the buffer shaft tube 1032 through the transfer valve port 1031, and the liquid pushes the bearing impeller 1034 inside the buffer shaft tube 1032 to rotate when entering, thereby reducing the pressure at the catalyst input end, and then the catalyst enters the liquid storage chamber 1035 in the liquid storage pipe 1033 through the inner through pipe 1036 at the bottom of the bearing impeller 1034.

[0049] Specifically, a guide rod 1041 is provided inside the cylinder assembly 104, and the guide rod 1041 is telescopically connected to the cylinder assembly 104, and the guide rod 1041 passes through the bearing impeller 1034 and extends to the inside of the liquid storage pipe 1033, and a cylinder piston 1047 is provided at the bottom of the guide rod 1041, and the cylinder piston 1047 is threadedly connected to the flow control valve sleeve 1042, and a float chamber 1046 is provided inside the flow control valve sleeve 1042, and a plurality of valve columns 1045 are provided at the bottom of the float chamber 1046, and a float plug 1043 is located inside the float chamber 1046, and the float plug 1043 is slidably connected to the flow control valve sleeve 1042, and the valve column 1045 is connected to the float plug 1043 through the through hole 1044. When the catalyst needs to be added, the cylinder assembly 104 controls the guide rod 1041 to extend outward, thereby pushing the cylinder piston at the front end. 1047 is separated from the liquid storage chamber 1035, allowing the catalyst to enter the float chamber 1046 inside the flow control valve sleeve 1042. With the continuous injection of the catalyst, the float 1043 will rise along the valve column 1045 until the valve column 1045 is separated from the through hole 1044 on the surface of the float 1043. At this time, the catalyst can enter the synthesis reaction tank 1 through the through hole 1044 to react with the raw material. When the injected catalyst dosage meets the standard, the cylinder assembly 104 controls the guide rod 1041 to be retracted, and the float 1043 slides downward under the influence of negative pressure suction and the internal pressure of the tank body. The through hole 1044 is recombined with the valve column 1045, so that the catalyst in the float chamber 1046 cannot react with the raw material of the tank body, and the raw material inside the tank body cannot enter the float chamber 1046 and the liquid storage chamber 1035.

[0050] The working principle of the above technical solution is as follows: the catalyst is pre-stored inside the catalyst storage tank 3, and when in use, the catalyst is pumped from the inside of the tank body to the embedded agent tube 103 through the delivery motor 4, and then the embedded agent tube 103 is used to accurately control the dosage delivered to the inside of the synthesis reaction tank 1, and the catalyst enters the buffer shaft tube 1032 through the switching valve port 1031. When the liquid enters, it will push the bearing impeller 1034 inside the buffer shaft tube 1032 to rotate, which can reduce the pressure at the catalyst input end, and then the catalyst enters the liquid storage chamber 1035 in the liquid storage pipe 1033 through the internal through pipe 1036 at the bottom of the bearing impeller 1034. When the catalyst needs to be added, the cylinder assembly 104 controls the guide rod 1041 to extend outward, thereby pushing the cylinder piston 1047 at the front end. The catalyst is separated from the liquid storage chamber 1035, and enters the float chamber 1046 inside the flow control valve sleeve 1042. As the catalyst is continuously injected, the float plug 1043 will rise along the valve column 1045 until the valve column 1045 is separated from the through hole 1044 on the surface of the float plug 1043. At this time, the catalyst can enter the synthesis reaction tank 1 through the through hole 1044 to react with the raw material. When the injected catalyst dosage meets the standard, the cylinder assembly 104 controls the guide rod 1041 to be retracted, and the float plug 1043 slides downward under the influence of negative pressure suction and the internal pressure of the tank body. The through hole 1044 is recombined with the valve column 1045, so that the catalyst in the float chamber 1046 cannot react with the raw material of the tank body, and the raw material inside the tank body cannot enter the float chamber 1046 and the liquid storage chamber 1035.

After the adjustment, the pressure monitoring data is continued to be judged. If the pressure monitoring data is abnormal for more than three times, it will automatically stop and alarm;

[0065] Specifically, through real-time monitoring of the pressure sensing element 306 and the damping sensing element 307, the pressure change data between the boost pump 302 and the shunt pipe 305 and the operating damping data of the stirring motor 303 can be accurately obtained, ensuring real-time monitoring of key parameters in the production process. The monitoring data analysis and coordination module receives, analyzes and controls the real-time monitoring data, and can compare it with the preset standard data, timely discover abnormalities and take corresponding adjustment measures, ensuring the stability and safety of production.
