[0026] The medicinal materials of Lindera aggregata are directly put into the interior of the stirring device through the feed inlet, causing the materials to accumulate in one place and making it impossible to quickly stir them evenly, which affects the working efficiency. Most of the materials in the reaction kettle are at the lower end of the stirrer, resulting in the materials at the upper end being difficult to stir and adhering to the inner wall surface. This not only makes it impossible to stir them but also forms dirt, affecting subsequent use. Therefore, through research, the inventor provides a closed extraction device for alkaloids of Lindera aggregata. By setting up a reflux component, the processed materials inside the sealed tank can be stirred multiple times by reflux, thus avoiding the uneven stirring of the processed materials accumulated in the upper part of the sealed tank, improving the working efficiency of the stirring process, preventing the adhesion of the processed materials to the inner wall of the sealed tank due to long-term retention, enhancing the processing flow rate between the processed materials, and during the reflux process, the spiral blades can also accelerate the discharge speed of the processed materials accumulated at the discharge port, thus avoiding the accumulation and blockage of the processed materials and accelerating the working efficiency of the discharge, which is convenient for use and solves the above defects.

The top end of the condenser 11 is connected to a delivery pipe 13, and the delivery pipe 13 is connected to an external condensed water storage device. In this way, the air pressure inside the sealed tank 1 can be monitored through the pressure gauge 12. When the air pressure is too high, condensed water can be added through the delivery pipe 13, and the flow rate of the condensed water in the condenser 11 can be gradually increased to quickly exchange heat with the gas phase inside the sealed tank 1, thereby reducing the air pressure inside the sealed tank 1. A reflux component 2 is arranged at the top of the sealed tank 1, a constant temperature control device 3 is connected to the outer surface of the sealed tank 1, and a pH value adjustment device 4 and a pH value detection device 5 are sequentially connected to the outer surface of the sealed tank 1;

The outer surface of the chain 26 is connected with a push rod 29, and a through cavity adapted to the push rod 29 is provided on one side of the storage tank 23. The outer surfaces of the rotating rod 24 and the round rod 27 are respectively connected with two belt pulleys 28, and the two belt pulleys 28 are drivingly connected by a belt. The outer surfaces of the two fixed boxes 21 are slidably connected with a moving frame 210. The inner side of the moving frame 210 is slidably connected with the outer surface of the push rod 29;

[0030] Please refer to Figures 2 to 7 , the outer surface of the moving frame 210 is connected with a connecting box 211. The inner cavity of the connecting box 211 is threadedly connected with a second motor 212, and the shape of the connecting box 211 is T-shaped. The top of the inner cavity of the connecting box 211 is rotatably connected with a long rod 213. The output shafts of the long rod 213 and the second motor 212 are respectively connected with two meshing gears 214. The bottom end of the long rod 213 penetrates into the inner cavity of the sealed tank 1. The contact area where the long rod 213 penetrates the sealed tank 1 is sealed. The outer surface of the long rod 213 is connected with a pressure plate 215, and the cross-sectional area of the pressure plate 215 is smaller than the inner cavity of the sealed tank 1. The outer surface of the long rod 213 is connected with a spiral blade 216, and the spiral blade 216 is located below the pressure plate 215. The bottom of the inner cavity of the sealed tank 1 is communicated with a retention pipeline 217. The inner cavity of the retention pipeline 217 is used in cooperation with the spiral blade 216. An impurity pump 218 is installed on the outer surface of the sealed tank 1. The discharge and feed ends of the impurity pump 218 are both communicated with a discharge pipeline 219;

[0031] Please refer to Figures 3 to 7 , one end of one of the discharge pipelines 219 is communicated with the retention pipeline 217. The discharge pipeline 219 connected to the feed end of the impurity pump 218 is communicated with the retention pipeline 217.

[0032] Specifically, start the first motor 22. The first motor 22 drives the round rod 27 to rotate. The round rod 27 drives the pulley 28, the rotating rod 24, and the sprocket 25 to rotate together. The sprocket 25 drives the chain 26 to move synchronously. The chain 26 drives the push rod 29 to move synchronously. While the push rod 29 is moving, by virtue of the sliding connection relationship, it pushes the moving frame 210 to move up and down. The moving frame 210 drives the connection box 211, the second motor 212, the gear 214, the long rod 213, the spiral blade 216, and the pressure plate 215 to move down synchronously. During the movement, start the second motor 212. The second motor 212 drives the gear 214 to rotate meshingly. The gear 214 drives the long rod 213, the pressure plate 215, and the spiral blade 216 to rotate together, thereby mixing and stirring the processed material, and while stirring, pressing the processed material downward for backflow. At this time, the processed material is pressed into the retention pipe 217. Start the impurity pump 218. The impurity pump 218 discharges the processed material in the retention pipe 217 back into the top of the inner cavity of the sealed tank 1 through the discharge pipe 219, so as to flow the material accumulated at the top of the sealed tank 1 into the bottom of the sealed tank 1 for mixing and stirring processing, and prevent the processed material stored in the retention pipe 217 from being blocked. The spiral blade 216 can be used for stirring to accelerate the flow rate of the retained processed material, thereby accelerating the discharging working condition, which is convenient for use.

[0033] In summary, the working principle of a closed extraction device for lindera aggregata alkaloids according to an embodiment of the present invention is as follows: First, the user pours the lindera aggregata processed material and auxiliary medicaments into the sealed tank 1. Then start the reflux assembly 2. The reflux assembly 2 first presses the processed material downward from the top of the inner cavity of the sealed tank 1, and while pressing, the processed material can be mixed and processed by the rotation of the spiral blade 216. Then, while mixing, it is pressed downward into the retention pipe 217, and then the processed material is reflowed into the inner cavity of the sealed tank 1 by the reflux assembly 2 for uniform mixing and stirring, so as to achieve the technical effect of uniform stirring. And during the stirring process, the internal temperature of the sealed tank 1 can be heated and controlled by the constant temperature control device 3. At this time, the mixture of the medicinal materials (lindera aggregata, solid powder) and chloroform extraction solvent processed in the sealed tank 1 is heated and vaporized. After the mixed solvent is heated and vaporized, it enters the condenser 11, and after heat exchange, it flows back into the sealed tank 1 in the form of a liquid. The extraction time is 3 h. Thus, through the repeated extraction of the sealed tank 1 and the condenser 11, the extraction purity is gradually improved. Finally, it is discharged through the retention pipe 217, which is convenient for use.
