[0002] The gradient extraction equipment for traditional Chinese medicine is a device used to extract active ingredients during the manufacturing process of traditional Chinese medicine. Its main function is to extract various target components from traditional Chinese medicine by gradually increasing the solvent concentration in stages. The gradient extraction process can be optimized by controlling parameters such as the temperature, concentration and flow rate of the solvent to improve extraction efficiency and the purity of the extract.

[0003] Existing gradient extraction devices for traditional Chinese medicine often have residual extracts deep within the tissues of the herbs. Due to the lack of an effective filtration mechanism, a considerable portion of the extract remains in the herbs during the extraction process, resulting in waste of raw materials and reduced extraction efficiency. Therefore, there is a problem in collecting the residual extracts from the herbs. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 4 As shown, a gradient extraction device for Chinese herbal medicine includes a support frame 1, an extraction cylinder 2, an extrusion mechanism 3, a vacuum pump 4, a condensation device 5 and a heating mechanism 6. The extraction cylinder 2 is fixedly connected to the outer surface of the support frame 1, the extrusion mechanism 3 is fixedly connected to the upper surface of the extraction cylinder 2, the vacuum pump 4 is fixedly connected to the upper surface of the support frame 1, the condensation device 5 is fixedly connected to the outer surface of the extraction cylinder 2, and the heating mechanism 6 is fixedly connected to the inner wall of the extraction cylinder 2. The extrusion mechanism 3 includes a first electric telescopic rod 301 fixedly connected to the upper surface of the extraction cylinder 2, the output end of the first electric telescopic rod 301 passes through the inner wall of the extraction cylinder 2 and is fixedly connected to a lower pressure plate 305, the outer surface of the lower pressure plate 305 is slidably connected to the inner wall of the extraction cylinder 2, and the upper surface of the extraction cylinder 2 is fixedly connected to a protective frame 306.

[0024] In order to discharge the residual extract in the Chinese herbal medicine, the squeezing mechanism 3 also includes a second electric telescopic rod 302 fixedly connected to the outer surface of the support frame 1. The output end of the second electric telescopic rod 302 is fixedly connected to the filter bottom shell 303. The upper surface of the filter bottom shell 303 is in contact with the lower surface of the extraction cylinder 2. The second electric telescopic rod 302 is provided with four groups to facilitate supporting the filter bottom shell 303. By starting the second electric telescopic rod 302, the output end of the second electric telescopic rod 302 drives the filter bottom shell 303 to move downward, thereby facilitating the discharge of the extracted Chinese herbal medicine in the extraction cylinder 2. The inner side surface of the filter bottom shell 303 is fixedly connected to a filter plate 307, and the lower surface of the filter bottom shell 303 is fixedly connected to a water pump 304. The filter plate 307 is used to filter the extract in the Chinese herbal medicine, and then the water pump 304 is started to quickly discharge the extract from the filter bottom shell 303. The lower surface of the extraction cylinder 2 is fixedly connected to a sealing gasket 308, and the outer surface of the sealing gasket 308 is fitted with the groove opened on the upper surface of the filter bottom shell 303. The sealing gasket 308 can prevent water leakage from occurring at the connection between the filter bottom shell 303 and the extraction cylinder 2.

[0025] It is worth mentioning that starting the water pump 304 facilitates the discharge of the extract in the extraction cylinder 2 and the filter bottom shell 303, and then starting the first electric telescopic rod 301. The output end of the first electric telescopic rod 301 drives the lower pressure plate 305 to slide downward, thereby facilitating the squeezing of the Chinese herbal medicine, so that the residual extract in the Chinese herbal medicine passes through the filter plate 307 and falls on the inner side of the filter bottom shell 303, thereby facilitating the rapid removal of the residual extract in the Chinese herbal medicine. At the same time, the lower pressure plate 305 slides on the inner wall of the extraction cylinder 2, thereby facilitating the cleaning of the inner wall of the extraction cylinder 2.

[0026] In order to uniformly heat the extract, the heating mechanism 6 includes a temperature sensor 603 fixedly connected to the inner wall of the extraction cylinder 2, and a cavity 601 is opened inside the extraction cylinder 2, and the cavity 601 is filled with mineral oil, wherein a resistance heating wire 604 is embedded in the extraction cylinder 2, and the outer surface of the extraction cylinder 2 is fixedly connected to the feed cover 201, and the resistance heating wire 604 is used to heat the extract and the Chinese herbal medicine mixture in the extraction cylinder 2, wherein the heating mechanism 6 also includes a motor 602 fixedly connected to the lower surface of the filter bottom shell 303, and the output shaft of the motor 602 passes through the inner side surface of the filter bottom shell 303 and is fixedly connected to the stirring blade 605. By starting the motor 602, the output shaft of the motor 602 drives the stirring blade 605 to rotate, so that the stirring blade 605 can easily drive the extract to rotate, so that the extract and the Chinese herbal medicine can be evenly heated.

[0027] It is worth mentioning that when the resistance heating wire 604 is activated, the heat generated by the resistance heating wire 604 is transferred through the heat transfer, which heats the mineral oil in the cavity 601. This allows the heat generated by the resistance heating wire 604 to be evenly transferred to the inner wall of the extraction cylinder 2. Then, the motor 602 is activated, and the output shaft of the motor 602 drives the stirring blade 605 to rotate. The rotation of the stirring blade 605 causes the extract to form a swirling flow in the extraction cylinder 2, which facilitates the even heating of the extract.

[0028] Working principle: The herbal medicine and extract are added to the extraction cylinder 2 through the feed cover 201. Then, the resistance heating wire 604 is activated. The heat from the resistance heating wire 604 is transferred through combustion, heating the mineral oil in the cavity 601. This heat is then evenly transferred to the inner wall of the extraction cylinder 2. Next, the motor 602 is activated. The output shaft of the motor 602 drives the stirring blades 605 to rotate. The rotation of the stirring blades 605 creates a swirling flow of the extract within the extraction cylinder 2, ensuring even heating. After extraction is complete, the water pump 304 is activated to drain the extract from the extraction cylinder 2 and the filter bottom shell 303. Then, the first electric motor is activated. The first electric telescopic rod 301 drives the lower pressure plate 305 to slide downwards, which facilitates the squeezing of the Chinese herbal medicine. This allows the residual extract in the Chinese herbal medicine to pass through the filter plate 307 and fall onto the inner side of the filter bottom shell 303, making it easier to quickly remove the residual extract from the Chinese herbal medicine. At the same time, the lower pressure plate 305 slides on the inner wall of the extraction cylinder 2, which facilitates the cleaning of the inner wall of the extraction cylinder 2. Then, multiple sets of second electric telescopic rods 302 are activated. The output end of the second electric telescopic rod 302 drives the filter bottom shell 303 to move downwards, which separates the filter bottom shell 303 from the extraction cylinder 2, making it easier to clean the Chinese herbal medicine residue in the extraction cylinder 2.
