[0002] Traditional Chinese medicine extraction is a crucial step in preparing TCM raw material solutions. During the heating process of extracting the active ingredients from the TCM materials in the extraction tank, the active ingredient content is primarily controlled by the boiling state of the material in the extraction tank, which significantly affects the stability of the active ingredient content.

[0003] At present, the mainstream automated production process of extraction tanks mainly controls the boiling state in the extraction tank indirectly by controlling the temperature of the material in the extraction tank. The existing control method cannot accurately control the boiling state of the liquid medicine in the extraction tank. The boiling state is affected by the temperature and pressure of the liquid medicine in the tank body. Simply controlling the material temperature cannot control the boiling state of the liquid medicine in the tank in real time, which can easily cause excessive boiling or unsatisfactory boiling state in the tank, resulting in unstable content of effective substances in the extract.

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, a preferred embodiment of the present invention proposes an extraction tank with a boiling state control device, which mainly includes a tank body 1, a visual camera 5, a video analysis mechanism 3, a heating device 2, a PLC control module 4, a condenser 6, a cooler 7, an oil-water separator 8 and other components, wherein the top of the tank body 1 is provided with a feed port, and the bottom is provided with a discharge port, through which Chinese medicinal materials can be put into the tank body 1, and finally, the medicinal residue formed after the effective ingredients in the Chinese medicinal materials are extracted will come out from the discharge port.

[0025] A cover is installed at the discharge port, which is hinged to the bottom of the tank body 1. Cylinders are installed on both the front and rear sides of the cover to control the locking of the cover. Cylinders are also installed on the left and right sides of the cover to control the flipping of the cover so that the cover is fully opened.

[0026] like Figure 2 As shown, the heating device 2 is composed of a jacket 21, three steam pipes 22, and a condensate outlet pipe 24. The jacket 21 is wrapped around the outer periphery of the tank body 1, and a heating layer is provided between the jacket 21 and the tank body 1, thereby forming a heating chamber. The three steam pipes 22 are respectively located at the upper side, middle part, and bottom part of the tank body 1. The three steam pipes 22 are connected to the heating chamber to provide heating steam for the heating chamber. Each steam pipe 22 is equipped with an outlet valve 23 for controlling the flow of steam on the corresponding pipe. The three steam pipes 22 will be connected to a main pipe, which is in turn connected to a steam generating source. A main outlet valve 23 is also installed on the main pipe to control the steam in the main pipe.

[0027] The heating chamber is filled with high-temperature steam, which heats the Chinese medicinal materials in the tank 1. The high-temperature steam in the heating chamber condenses into water, which eventually flows out of the condensate outlet pipe 24. The condensate outlet pipe 24 is connected to the drain assembly 9, which is used to continuously discharge the condensate in the heating chamber to the outside of the pipe. At the same time, it can automatically distinguish between steam and water, achieving the purpose of automatic steam blocking and water drainage.

[0028] refer to Figure 1 、 Figure 3 The condenser 6, cooler 7 and oil-water separator 8 are all located above the tank body 1, wherein the condenser 6 has two inlets and two outlets, the two inlets are connected to the two outlets respectively, the air outlet at the top of the tank body 1 is connected to one of the inlets of the condenser 6 through a pipe, and the outlet connected to the inlet is connected to the top of the cooler 7 through a pipe.

[0029] The cooler 7 also has two inlets and two outlets. The condenser 6 is connected to the inlet at the top of the cooler 7 through a pipe, and the outlet on the lower side of the cooler 7 is connected to the oil-water separator 8 through a pipe. The inlet at the bottom of the cooler 7 is connected to the cooling water pipe 10, and the outlet at the top of the cooler 7 is connected to another inlet at the bottom of the condenser 6 through a pipe, and the other outlet of the condenser 6 is connected to the water outlet pipe.

[0030] After the Chinese medicinal materials in the tank body 1 are heated, water vapor will be generated. The water vapor will flow into the condenser 6 through the pipe, and cooling water will be introduced into the cooler 7 through the cooling water pipe 10. The cooling water will flow into the cooler 7 and condenser 6 in sequence, and finally flow out from the water outlet pipe. After passing through the condenser 6, the water vapor will condense into water liquid, which will then flow into the cooler 7, exchange heat with the cooling water, and finally flow into the oil-water separator 8. The bottom of the oil-water separator 8 has a water outlet and an oil outlet, and the water outlet will be connected to the side of the tank body 1 through a pipe. After the water liquid flowing into the oil-water separator 8 is separated into oil and water, the water will flow back to the tank body 1 through the pipe, and the oil will flow out from the oil outlet.

[0031] Two S-bends will be formed on the pipe connecting the oil-water separator 8 and the tank body 1. The upward S-bend will be higher than the bottom surface of the oil-water separator 8 by a certain height to prevent water from flowing back into the oil-water separator 8, while the downward S-bend is used to store a certain amount of water to form a water seal to prevent water vapor in the tank body 1 from flowing back into the oil-water separator 8.

[0032] like Figure 1 As shown, a viewing port is provided on the top of the tank body 1 , and a visual camera 5 is installed at the viewing port, and can capture the boiling condition of the liquid medicine in the tank body 1 through the viewing port.

[0033] The video analysis mechanism 3 is composed of a storage unit, a display unit and a processing module. The storage unit and the display unit are both electrically connected to the video analysis mechanism 3. The storage unit is used to store the image uploaded by the visual camera 5, and the processing module has a comparison unit. The processing module will process and analyze the image, and compare the image taken by the visual camera 5 with the standard image of boiling liquid medicine through the comparison unit, analyze the boiling condition of the liquid medicine in the tank body 1, and display the result on the display unit.

[0034] The PLC control module 4 is electrically connected to the video analysis mechanism 3, which transmits its results to the PLC control module 4. The outlet valve 23 in the heating device 2 is a solenoid valve, and the PLC control module 4 is electrically connected to the solenoid valve to control its operation. Based on the analysis results transmitted by the video analysis mechanism 3, the PLC control module 4 controls the operation of the outlet valve 23, thereby controlling the amount of steam introduced into the heating chamber, thereby controlling the heating temperature and indirectly controlling the boiling state of the liquid medicine in the tank 1.

[0035] The PLC control module 4 controls the operation of the heating device 2 on the extraction tank, controlling the extraction tank's heating. A video camera captures real-time images of the boiling material inside the extraction tank. The video analysis unit 3 receives these images and compares them with an internal database. The analysis results of the video analysis unit 3 are fed back to the heating device 2 in real time via the PLC control module 4, controlling the amount of steam introduced to the extraction tank. This process is controlled in real time until the extraction tank heating process is completed. At the end of the heating process, all systems are reset.

[0036] The above technical solutions only reflect the preferred technical solutions of the present utility model. Any changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the scope of protection of the present utility model.
