When covered, a tamping rod and at least one puncture portion protruding from the cover body can pierce the membrane and enter the first and second processing chambers respectively.

[0021] The embodiment of the present invention adopts the above technical solution, which has the following advantages:

[0022] 1. The present invention sets an extraction component as the core unit of the device, takes a primary extraction tank as the main body, and cooperates with a secondary extraction tank for deep extraction to achieve multi-stage continuous extraction and improve the extraction rate of effective ingredients. The stirring component improves the material mixing uniformity and mass transfer efficiency through mechanical stirring. The dead zone disturbance component eliminates the flow dead zone in the extraction tank through the guide structure. The support ring is fixed to the upper and lower ends of the inner side of the primary extraction tank. The hollow guide vertical pipes are arranged in a ring shape and equidistantly on the outside of the stirring inner shaft, covering the main material area. The outer guide channel pipes are arranged alternately at upper and lower inclined angles. When the stirring flow field drives the material to flow through, part of the fluid enters the guide channel pipe and is accelerated to form a turbulent jet, penetrating the material concentration gradient layer, and enhancing the local mixing effect. The composite hydrophobic coating prevents the material from adhering to and clogging the guide channel, ensuring long-term and stable operation of the device.

[0023] 2. The present invention realizes real-time adjustment of the flow area of ​​the guide channel tube by setting an aperture adjustment component. The vertical guide bar is fixed on the inner side of the support ring frame, and the L-shaped sliding inner rod drives the flexible adaptive inner plate to slide. The position of the liquid hole ring is controlled by the magnetic connection force between the electromagnetic inner block and the L-shaped sliding inner rod to realize the switching of the aperture size. This design meets the needs of rapid mixing in the early stage of extraction and precise control in the later stage, thereby improving the flexibility and adaptability of the extraction process.

[0024] 3. The present invention ensures the sealing of the guide channel during the aperture adjustment process by providing a sealing component. The raised matching sealing ring is made of fluororubber with good corrosion resistance and elasticity, and fits tightly with the annular groove of the guide channel tube to form a reliable seal, prevent the leakage of the extractant, and ensure the safety and stability of the extraction process.

[0025] 4. The present invention realizes automatic control of the extraction process by setting up auxiliary intelligent control components through a distributed sensor network and an intelligent control terminal. The distributed concentration sensor on the outside of the vertical auxiliary rod collects the material concentration data in the tank in real time and transmits it to the power box of the control terminal. The built-in PLC control system and AI algorithm module of the control terminal calculate the mixing uniformity index according to the concentration distribution, dynamically adjusts the aperture of the diversion channel, and enhances the fluid injection amount in the uneven mixing area. At the same time, it adjusts the parameters such as the heating jacket temperature and the stirring component speed to realize fully automatic intelligent control of the extraction process and improve the consistency of extraction efficiency and product quality.

Therefore, the drawings and description are to be considered as illustrative in nature and not restrictive.

[0043] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. Example 1

The output end of the external mounting base motor 200 is connected to the stirring inner shaft 201, which extends to the inside of the primary extraction tank 100. The outer side of the stirring inner shaft 201 is fixedly connected to a plurality of spirally arranged oblique stirring blade rods 202. The end of the oblique stirring blade rod 202 away from the stirring inner shaft 201 is fixedly connected to a strong shear stirring blade 203.

[0047] The dead zone spoiler assembly 3 includes two support frames 300, which are fixedly connected to the upper and lower ends of the inner side of the primary extraction tank 100 respectively. A plurality of hollow flow guide vertical pipes 301 are fixedly connected between the upper and lower support frames 300, and a plurality of flow guide channel tubes 302 are fixedly connected to the outer sides of the hollow flow guide vertical pipes 301.

[0048] The aperture adjustment assembly 4 includes multiple groups of vertical guide rails 401, which are fixedly connected to the inner side of the support ring frame 300. One group of vertical guide rails 401 includes vertical guide rails 401 arranged on the upper and lower sides of the guide channel tube 302. The inner ends of the vertical guide rails 401 are slidably connected with L-shaped sliding inner rods 402. The ends of the two L-shaped sliding inner rods 402 close to each other are fixedly connected with flexible adaptive inner plates 403. Liquid hole rings 404 are sequentially opened on the outer sides of the flexible adaptive inner plates 403 from top to bottom. A guide spring 405 is fixedly connected between the horizontal surface of the L-shaped sliding inner rod 402 and the vertical guide rail 401. The left and right inner walls of the vertical guide rail 401 are symmetrically fixedly connected with multiple groups of electromagnetic inner blocks 400.

[0049] Multiple groups of electromagnetic inner blocks 400 and corresponding L-shaped sliding inner rods 402 are magnetically connected to each other, multiple hollow guide tubes 301 are arranged in a ring shape at equal intervals on the outside of the stirring inner shaft 201, multiple guide channel tubes 302 are arranged vertically and equidistantly, and multiple adjacent guide channel tubes 302 are arranged alternately at upper and lower inclined angles. The outer wall of the hollow guide tube 301 is fixedly connected with a composite hydrophobic coating 303. The height of the hollow guide tube 301 is two-thirds of the height of the first-level extraction tank 100. The corresponding multiple liquid hole rings 404 have different diameters, and multiple flexible adaptive inner plates 403 and corresponding guide channel tubes 302 are connected and coordinated with each other.

[0050] The sealing assembly 5 includes a plurality of raised matching sealing rings 501, which are respectively fixedly connected to the outside of the corresponding liquid hole ring 404. A circular groove 500 is provided at one end of the guide channel tube 302 close to the flexible adaptation inner plate 403. The circular groove 500 and the corresponding raised matching sealing ring 501 cooperate with each other. The auxiliary intelligent control assembly 6 includes a plurality of vertical auxiliary rods 600, which are all fixedly connected between the two support ring frames 300. The plurality of hollow guide vertical pipes 301 and the vertical auxiliary rods 600 are arranged at intervals. Example 2

[0051] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 10 、 Figure 12 As shown, in one embodiment, a plurality of vertically equidistantly arranged distributed concentration sensors 601 are fixedly connected to the outer side of the vertical auxiliary rod 600, and a control terminal power box 602 is fixedly connected to the rear end of the secondary extraction tank 104. The control terminal power box 602 and the extraction component 1, the stirring component 2, the aperture adjustment component 4, and the auxiliary intelligent control component 6 are electrically connected.

[0052] By setting up an auxiliary intelligent control component 6, real-time monitoring and automatic control of the extraction process are achieved through a distributed sensor network and an intelligent control terminal. The vertical auxiliary rods 600 are spaced between the hollow guide pipes 301, and the distributed concentration sensors 601 fixed on the outside are arranged equidistantly along the height of the tank to collect the concentration data of the material in the tank in real time and transmit the data to the control terminal power box 602. The control terminal power box 602 has a built-in PLC control system and AI algorithm module, which can calculate the mixing uniformity index according to the concentration distribution data. By adjusting the on and off state of the electromagnetic inner block 400, the aperture of the guide channel is dynamically adjusted to enhance the fluid injection amount in the uneven mixing area. At the same time, the control terminal power box 602 can also adjust parameters such as the temperature of the heating jacket 105 and the speed of the stirring component 2 to achieve fully automated intelligent control of the extraction process.

[0053] When the present invention is working: the extraction component 1 is used as the core processing unit of the device, the first-level extraction tank 100 is filled with a mixture of Yao bath raw liquid and extractant, and the outer heating jacket 105 controls the temperature of the material in the tank by circulating hot water or steam to adapt to the extraction requirements of different Yao medicine components. The sealed tank cover 101 ensures the sealing of the extraction process to prevent the extractant from volatilizing and external pollution. The first-level extraction tank 100 forms a closed circulation loop with the circulation tank 103 and the second-level extraction tank 104 through the circulation infusion pipe 102. After the first-level extraction, the material is pumped into the circulation tank 103 through the circulation infusion pipe 102 for buffering, and then enters the second-level extraction tank 104 for deep extraction, realizing multi-stage continuous extraction.

[0054] The stirring component 2 improves the material mixing uniformity and mass transfer efficiency through mechanical stirring. The external mounting motor 200 drives the stirring inner shaft 201 to rotate, driving the oblique stirring blade rod 202 and the strong shear stirring blade 203 arranged in a spiral shape on the outside to operate. The spiral angle of the oblique stirring blade rod 202 is designed to be forty degrees. When rotating, it generates a composite flow field of axial and radial directions, so that the material forms a spiral upward and downward circulation flow, eliminating the concentration stratification of the material in the tank. The strong shear stirring blade 203 adopts a serrated edge structure, which effectively breaks up the Yao medicine fiber agglomerates and increases the contact area between the effective ingredients and the extractant.

[0055] The dead zone spoiler component 3 eliminates the flow dead zone in the extraction tank through the diversion structure and enhances the local mixing effect. The two support ring frames 300 are fixed at the upper and lower ends of the inner side of the first-level extraction tank 100. The multiple hollow diversion vertical pipes 301 connected therebetween are arranged in a ring shape and equidistantly on the outside of the stirring inner shaft 201. Their height is two-thirds of the height of the first-level extraction tank 100, covering the main material area. The diversion channel tubes 302 on the outside of the hollow diversion vertical pipes 301 are arranged alternately at an up and down tilt angle of 45° and are vertically equidistantly distributed. When the stirring flow field drives the material to flow through the hollow diversion vertical pipe 301, part of the fluid enters the diversion channel tube 302 and is accelerated to be ejected, forming a turbulent jet, penetrating the material concentration gradient layer. The composite hydrophobic coating 303 on the outside of the diversion channel tube 302 adopts a fluorosilicone modified polymer and nano-titanium dioxide composite system, which can prevent the material from adhering to and clogging the diversion channel, ensuring long-term stable operation.

[0056] The aperture adjustment component 4 realizes real-time adjustment of the flow area of ​​the guide channel tube 302 to adapt to the flow field requirements of different extraction stages. The vertical guide bar 401 is fixed to the inner side of the support ring frame 300, and the L-shaped sliding inner rod 402 can slide on the vertical guide bar 401. The flexible adaptive inner plate 403 at its end is connected to the guide channel tube 302. Liquid hole rings 404 of different diameters are provided on the flexible adaptive inner plate 403. The position of the liquid hole ring 404 is controlled by the magnetic connection force between the electromagnetic inner block 400 and the L-shaped sliding inner rod 402. When the electromagnetic inner block 400 is energized, a magnetic field is generated to attract the L-shaped sliding inner rod 402, compressing the guide spring 405, so that the larger diameter liquid hole ring 404 is aligned with the guide channel tube 302, increasing the flow rate; when the power is off, the guide spring 405 is reset, and the smaller diameter liquid hole ring 404 is connected to reduce the flow rate, meeting the needs of rapid mixing in the early stage of extraction and precise control in the later stage.

[0057] The sealing component 5 ensures the sealing of the guide channel during the aperture adjustment process to prevent leakage of the extractant. The raised matching sealing ring 501 is fixed to the outside of the liquid hole ring 404 and is made of fluororubber, which has good corrosion resistance and elasticity. The guide channel tube 302 is provided with a circular groove 500 at one end close to the flexible adaptation inner plate 403. When the liquid hole ring 404 is docked with the guide channel tube 302, the raised matching sealing ring 501 is embedded in the circular groove 500 to form a tight seal to ensure the safety and stability of the extraction process.

[0058] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
