[0048] The cartridge drive device includes a spline shaft 3 arranged coaxially vertically, a light shaft 301 coaxially fixed at the top of the spline shaft 3, the light shaft 301 penetrates to the outside of the kettle body 1, and a drive device 5 is fixed outside the kettle body 1, the drive device 5 drives the light shaft 301 to rotate.

[0049] In this embodiment, a passive wheel 3 is sleeved on the light shaft 301 outside the kettle body 1, a driving wheel 4 is arranged on the output shaft of the drive device 5, and the driving wheel 4 drives the passive wheel 3 to rotate. The drive device 5 adopts a motor with a speed reduction mechanism, and the passive wheel 3 and the driving wheel 4 both adopt gears and are meshed and connected.

[0050] The spline shaft 3 is sleeved with a lower sliding sleeve 8 arranged slidingly up and down, the lower sliding sleeve 8 is a spline through hole inside, which matches the horizontal section of the spline shaft 3, so that the spline shaft 3 can drive the lower sliding sleeve 8 to rotate. A plurality of connecting plates 7 are hinged to the lower sliding sleeve 8, and the connecting plates 7 are provided with cartridges 6 arranged with open upper ends at the ends.

[0051] The circumferential surface of the cartridge 6 is provided with a through hole, the upper end of the cartridge 6 is covered with an upper cover 601, and the upper cover 601 is threadedly connected with the cartridge 6, which effectively avoids the accidental opening and flying of the upper cover 601 during the rotation of the cartridge 6. The upper cover 601 is provided with an inverted U-shaped handle, which is convenient for rotating the upper cover 601 and taking it off.

[0052] The bottom of the kettle body 1 is connected with a stop valve 16, and the outside of the kettle body 1 is provided with a heating module.

[0053] In order to facilitate the taking and placing of Chinese herbal medicine in the cartridge 6, the cartridge 6 needs to be lifted when taking and placing the Chinese herbal medicine. Therefore, in this embodiment, the spline shaft 3 is sleeved with an upper sliding sleeve 10 arranged slidingly up and down, the upper sliding sleeve 10 is arranged above the lower sliding sleeve 8, and the upper sliding sleeve 10 and the connecting plate 7 are provided with an inclined pull rod 9.

[0054] The upper end of the diagonal tie rod 9 is hinged to the upper sliding sleeve 10, and a rotating shaft is convexly provided at the lower end of the diagonal tie rod 9. A sliding groove 701 is provided on the connecting plate 7, and waist-shaped holes are concavely provided on the inner walls on both sides of the sliding groove 701.

Once at its top dead center, cartridge 6 is positioned vertically, with connecting plate 7 positioned horizontally. Simultaneously, cartridge 6 moves directly below the feed port of kettle 1.

[0057] The Chinese herbal medicine can be taken in and out by opening the upper cover 601. The medicine cartridge 6 and the connecting plate 7 can also be detachably connected by hanging. When the Chinese herbal medicine needs to be taken in and out, the medicine cartridge 6 and the connecting plate 7 are separated and then taken out through the feed port of the kettle body 1.

[0058] Depend on Figure 7 As shown, the lifting device includes a lifting control mechanism 13 and a clamping mechanism 14. The clamping mechanism 14 includes a horizontally arranged telescopic rod 1401 and a clamping claw 1402. The two ends of the telescopic rod 1401 are fixedly connected to the clamping claw 1402 and the sliding part of the lifting control mechanism 13 respectively. The lifting control mechanism 13 adopts a vertically arranged electric linear module.

[0059] The clamping claw 1402 is detachably connected to the adjusting sleeve 12. Furthermore, the clamping claw 1402 is an elastic arc-shaped plate with an arc of 100° to 120°. The upper and lower ends of the circumferential surface of the adjusting sleeve 12 are both protruding with clamping rings, and the clamping claw 1402 is clamped between the two clamping rings.

[0060] The heating module includes a barrel body 18 , which is disposed below the exterior of the kettle body 1 , and the bottom and side surfaces of the barrel body 18 are spaced apart from the kettle body 1 .

[0061] Several heating devices 19 are provided inside the barrel body 18. In this embodiment, the heating device 19 adopts a constant temperature heating rod. The heating device 19 is fixedly connected to the circumferential surface of the inner wall of the barrel body 18 through a connecting frame and is arranged in the space between the side of the barrel body 18 and the kettle body 1.

[0062] The space between the barrel 18 and the kettle body 1 is filled with heat-conducting oil, and an oil filling hole with an oil cover and a pressure relief safety valve are arranged on the top surface of the barrel 18.

[0063] If the heat-conducting oil inside the barrel 18 does not flow, the temperature field of the heat-conducting oil will not be uniform due to the distance from the heating device 19, resulting in uneven heating of the kettle body 1. In order to solve this problem, in the present embodiment, a plug-in shaft 15 is coaxially arranged inside the kettle body 1, and a part of the plug-in shaft 15 is located inside the kettle body 1 and another part is arranged outside the kettle body 1 below. A lower baffle 1501 is sleeved on the plug-in shaft 15, and the bottom surface of the lower baffle 1501 abuts against the bottom surface of the kettle body 1.

[0064] A spline hole 1503 is concavely arranged on the top surface of the plug-in shaft 15, and the bottom of the spline shaft 3 is inserted into the spline hole 1503. A drain pipe 1504 is fixed to the bottom of the plug-in shaft 15, and the drain pipe 1504 is arranged outside the barrel 18 below and connected in series with the stop valve 16.

[0065] A plurality of paddles 17 are arranged around the axis of the drain pipe 1504 outside the drain pipe 1504, and the paddles 17 are arranged in the space between the kettle body 1 and the barrel 18. A plurality of through holes 1502 are arranged on the drain pipe 1504. The drain pipe 1504 with the through holes 1502 is covered by a liquid collecting tank 102, and the liquid collecting tank 102 is connected to the inside of the kettle body 1 through the drain hole 101 in the bottom surface of the kettle body 1.

[0066] When the spline shaft 3 rotates, the paddles 17 also rotate, thereby stirring the heat-conducting oil to make the heat-conducting oil flow, and the temperature field of the heat-conducting oil in each region is uniform, thereby optimizing the heating effect of the kettle body 1.

[0067] The liquid in the kettle body 1 flows into the inside of the liquid collecting tank 102 through the drain hole 101, then flows into the drain pipe 1504 through the through holes 1502, and finally is discharged through the opened stop valve 16.

[0068] During the extraction of Chinese herbal medicine by water extraction method, the water in the kettle body 1 evaporates, thereby causing the ratio of distilled water to Chinese herbal medicine. In order to maintain the ratio and continue to utilize the evaporated distilled water, in the present embodiment, a condensation reflux device 20 is connected to the top of the kettle body 1.

[0069] The condensation reflux device 20 comprises a steam rising pipe 2001, a condensation cylinder 2002 and a reflux pipe 2004 connected in sequence, the height of the steam rising pipe 2001 is greater than the height of the reflux pipe 2004, and the condensation cylinder 2002 is arranged obliquely. A one-way valve can be connected in series on the reflux pipe 2004 to prevent the steam from flowing upward from the inside of the reflux pipe 2004.

[0070] A plurality of condensation plates 2003 are provided at intervals inside the condensation cylinder 2002, and a plurality of fins can be provided outside the condensation cylinder 2002 for heat dissipation.

[0071] The steam inside the kettle body 1 moves upward through the steam riser 2001 and then flows into the condensation cylinder 2002. During the flow, it contacts the condensation plate 2003, cools down and condenses into water droplets, flows downward at an angle, and finally re-enters the interior of the kettle body 1 through the reflux pipe 2004.

[0072] A Chinese herbal medicine extraction method, based on the above-mentioned Chinese herbal medicine extraction device, comprises the following steps:

[0073] S01. Grind the liquorice until the particle size of the liquorice after grinding is between 0.7 mm and 5 mm.

[0074] Large particles will reduce the contact area between the solvent and the medicinal materials, thereby reducing the extraction rate of the active ingredients; while overly fine powders may cause the material to agglomerate, which is also not conducive to the extraction of active ingredients and may increase the difficulty of filtration.

[0075] The optimal particle size for grinding is 4.5mm, which helps to improve the extraction rate of active ingredients while ensuring good fluidity. This particle size ensures that the active ingredients of the medicinal materials can be fully extracted without causing operational inconvenience due to being too small.

[0076] S02. Extend the telescopic rod 1401 so that the claw 1402 is engaged with the adjusting sleeve 12, and the sliding part of the lifting control mechanism 13 moves upward, lifting the adjusting sleeve 12, and then moving the cartridge 6 upward through the vertical pull rod 11, the upper sleeve 10, the inclined pull rod 9 and the connecting plate 7. When the cartridge 6 moves to the top, the connecting plate 7 is arranged horizontally.

[0077] S03, open the cover 2, the upward medicine cartridge 6 is located just below the feed port of the kettle body 1, and the crushed licorice is placed inside the medicine cartridge 6. It can be placed directly, or the licorice can be placed inside a water-permeable bag, and then the bag is placed into the medicine cartridge 6 as a whole.

[0078] S04. Lower the medicine cartridge 6, disconnect the claw 1402 from the adjustment sleeve 12, and add distilled water to the interior of the kettle 1 through the feed port of the kettle 1. The distilled water level is higher than the medicine cartridge 6. The ratio of distilled water to licorice is 1:10 to 1:20, that is, 10-20 ml of water for every gram of dry medicinal material.

[0079] S05. Soak the licorice in the medicine cartridge 6 in distilled water for 6 to 14 hours, then heat the distilled water in the kettle 1 through the heating module, heat it to boiling, and keep it in a slightly boiling state for 1 to 3 hours to decoct the licorice.

[0080] During the decocting process, the distilled water evaporated is recondensed by the condensation reflux device 20 and flows back into the kettle body 1, thereby maintaining the initial ratio of the distilled water and the liquorice.

[0081] S06, when the distilled water in the kettle body 1 is kept in a micro-boiling state, the driving device 5 drives the cartridge 6 to rotate, and the rotating speed of the cartridge 6 is 10 r / min to 20 r / min. During the rotation of the cartridge 6, the distilled water in the kettle body 1 can be driven to flow, thereby playing a stirring effect and ensuring that the effective component concentration dissolved in the distilled water is consistent.

[0082] S07, after the decocting is completed, the stop valve 16 is opened to discharge the distilled water, and after the liquid level of the distilled water is lower than the cartridge 6, the driving device 5 increases the power, and the rotating speed of the cartridge 6 is 240 r / min to 500 r / min. In this way, the water adhered to the liquorice in the cartridge 6 is thrown out by the way of centrifugal spinning.

[0083] S08, the distilled water is added into the kettle body 1 again, and the above steps S05 to S07 are repeated for 2 or 3 times.

[0084] S09, after the extraction is completed, the cartridge 6 is moved upward, and the liquorice in the cartridge 6 is taken out.

[0085] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of the knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
