DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a Chinese medicine extraction device, such as Figure 1-4 As shown, it includes an extraction tank 1, in which an extraction chamber is provided; an extraction component arranged in the extraction chamber; and a filter tank 2 arranged beside the extraction tank 1; and a filter component arranged in the filter tank 2; wherein the extraction component includes: a hydraulic rod 301 arranged at the top of the extraction chamber, the output end of the hydraulic rod 301 is connected to a pressure plate 302, and an extraction cylinder 303 is arranged directly below the pressure plate 302, and the extraction cylinder 303 is connected to the bottom of the extraction chamber through a bearing; a servo motor 304 is arranged at the bottom of the extraction tank 1, and the output end of the servo motor 304 is fixedly connected to the end key of the extraction cylinder 303.

[0023] It should be noted that, due to the low utilization rate of Chinese medicine in the existing Chinese medicine extraction process, there is no equipment for squeezing the extracted Chinese medicine inside, and the effective substances in the medicine residue cannot be fully released; and most of the extraction devices are static, the relative flow between the solvent and the medicinal materials in the tank is slow, the extraction efficiency is generally low, and the contact and mixing rate between the solvent and the medicinal materials needs to be improved. In this scheme, by setting an extraction component, the rotatable extraction cylinder 303 can increase the flow rate of the water flow in the extraction chamber, so that the effective ingredients in the medicinal materials are quickly dissolved in the solvent, and at the same time, it can also promote the material exchange between the solvent and the medicinal materials and accelerate the diffusion rate; cooperating with the pressing plate 302 to squeeze the medicinal materials, it can promote the release of the effective ingredients in the medicinal materials, help to extract more effective ingredients, and improve the extraction efficiency of the medicinal materials.

[0024] Specifically, in this embodiment, the scheme mainly includes an extraction tank 1, an extraction component, a filter tank 2 and a filter component; the extraction component includes a hydraulic rod 301 arranged at the top of the extraction chamber, the output end of the hydraulic rod 301 is connected to a pressure plate 302, and an extraction cylinder 303 is arranged directly below the pressure plate 302, and the extraction cylinder 303 is connected to the bottom of the extraction chamber through a bearing; a servo motor 304 is arranged at the bottom of the extraction tank 1, and the output end of the servo motor 304 is fixedly connected to the end key of the extraction cylinder 303; the extraction cylinder 303 mainly functions to contain medicinal materials and solvents. During the extraction process of medicinal materials, the medicinal materials are placed in the extraction cylinder 303, and The extraction cylinder 303 is connected to the bottom of the extraction chamber through a bearing, so that the medicinal material can rotate in the extraction chamber. This rotation action not only increases the flow rate of the water flow in the extraction chamber, but also enables the effective ingredients in the medicinal material to dissolve more quickly in the solvent. After the rotation release is completed, the extraction cylinder 303 will stop rotating. At this time, the hydraulic rod 301 is subjected to the hydraulic pressure and repeatedly pushes the pressing plate 302 downward. Since the pressing plate 302 is facing the extraction cylinder 303, it can tightly press the medicinal material. This repeated pressing action increases the contact area and time between the medicinal material and the solvent, so that the effective ingredients in the medicinal material can be squeezed out more completely, thereby improving the extraction efficiency.

[0025] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a pump body 4 is provided between the extraction tank 1 and the filter tank 2 , the feed end of the pump body 4 is connected to the extraction tank 1 through a material guide pipe 5 , and the discharge end of the pump body 4 is connected to the filter tank 2 through a material guide pipe 5 .

[0026] In this embodiment, the extraction liquid in the extraction tank 1 will be pumped into the guide pipe 5 by the pump body 4, and then flow to the feed end of the pump body 4. The pump body 4 pushes the mixture in the extraction tank 1 into the guide pipe 5, and transports it to the filter tank 2 through the guide pipe 5.

[0027] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the filter material assembly includes a filter frame 601 arranged in the filter material tank 2, the filter frame 601 is arranged at an angle, and a filter screen 602 is installed in the filter frame 601; and a liquid discharge port 603 is arranged in the middle position of the filter material tank 2, and a slag discharge port 604 connected to the inner cavity of the filter material tank 2 adjacent to the lower side of the filter frame 601 is provided.

[0028] In this embodiment, when the extract enters from the top of the filter tank 2, it will first contact the inclined filter screen 602. As the extract flows on the filter screen 602, the pure extract will penetrate through the mesh of the filter screen 602 to the bottom thereof. The pure extract can then flow out from the bottom of the filter tank 2 through the drain port 603. At the same time, the main function of the filter screen 602 is to intercept solid particles and impurities to ensure the purity of the extract. Since the surface of the filter screen 602 has a certain inclination angle, the drug residue and other solid impurities will slide downward along the surface of the filter screen 602 under the action of gravity. This design helps to effectively remove solid impurities and prevent them from accumulating on the filter screen 602 or clogging the mesh. As impurities accumulate, they will continue to slide along the inclined surface of the filter screen 602 and eventually be discharged from the residue discharge port 604, thereby maintaining the continuous filtering effect of the filter screen 602 and the cleanliness of the filter tank.

[0029] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a sealing door 7 is hinged at the lower position of the side wall of the extraction tank 1.

[0030] In this embodiment, during the extraction process, the sealing door 7 can be closed to form a sealed state inside the extraction tank 1 to prevent leakage of the extraction liquid; during the slag discharge process, the sealing door 7 can be opened; the residue discharge process can be completed quickly and automatically; thereby making it convenient for the staff to clean the inside of the extraction tank 1.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a plurality of filtering holes 8 are formed through the side wall of the extraction cylinder 303 , and a side door 9 is hingedly connected to the side wall of the extraction cylinder 303 .

[0032] In this embodiment, the extract flows out from the side wall of the extraction cylinder 303 through the filter holes 8 on the side door 9, leaving the filter residue in the medicinal materials in the extraction cylinder 303 for subsequent centralized processing. The openable side door 9 is convenient for discharge, cleaning and maintenance.

[0033] In a further preferred embodiment of the present invention, Figure 4 As shown, the side of the pressing plate 302 opposite to the extraction cylinder 303 is arranged in a wavy pattern.

[0034] In this embodiment, the side of the pressing plate 302 opposite to the extraction cylinder 303 is arranged in a wavy pattern, which can increase the friction between the pressing plate 302 and the extraction cylinder 303, make the seal between the pressing plate 302 and the extraction cylinder 303 tighter, release the effective ingredients of the medicinal materials more thoroughly, and improve the extraction efficiency.

[0035] In a further preferred embodiment of the present invention, Figure 1-2 As shown, a water injection pipe 10 is connected to the bottom of the extraction tank 1 .

[0036] In this embodiment, a water injection pipe 10 is provided at the bottom side of the extraction tank 1 to facilitate more complete mixing between the medicinal materials and the water flow.

[0037] Working principle: The main function of the extraction cylinder 303 of this device is to accommodate medicinal materials and solvents. During the extraction process of medicinal materials, the medicinal materials are placed in the extraction cylinder 303, and the extraction cylinder 303 is connected to the bottom of the extraction chamber through a bearing, so that the medicinal materials can rotate in the extraction chamber. This rotation not only increases the flow rate of the water flow in the extraction chamber, but also enables the effective ingredients in the medicinal materials to be dissolved in the solvent more quickly. After the rotation is released, the extraction cylinder 303 will stop rotating. At this time, the hydraulic rod 301 is subjected to the hydraulic pressure and repeatedly pushes the pressing plate 302 downward. Since the pressing plate 302 is facing the extraction cylinder 303, it can tightly press the medicinal materials. This repeated pressing action increases the contact area and time between the medicinal materials and the solvent, so that the effective ingredients in the medicinal materials can be squeezed out more completely, thereby improving the extraction efficiency;

[0038] The extract flows out from the side wall of the extraction cylinder 303 through the filter hole 8 on the side door 9, leaving the filter residue in the medicinal material in the extraction cylinder 303 for subsequent centralized processing. The openable side door 9 is convenient for material discharge, cleaning and maintenance work;

[0039] The extraction liquid in the extraction tank 1 will be pumped into the guide pipe 5 by the pump body 4, and then flow to the feed end of the pump body 4. The pump body 4 pushes the mixture in the extraction tank 1 into the guide pipe 5, and then transports it to the filter tank 2 through the guide pipe 5.

[0040] When the extract enters from the top of the filter tank 2, it will first contact the inclined filter screen 602. As the extract flows on the filter screen 602, the pure extract will penetrate through the mesh of the filter screen 602 to the bottom thereof. The pure extract can then flow out from the bottom of the filter tank 2 through the drain port 603. At the same time, the main function of the filter screen 602 is to intercept solid particles and impurities to ensure the purity of the extract.

[0041] Since the surface of the filter screen 602 has a certain inclination angle, the drug residue and other solid impurities will slide downward along the surface of the filter screen 602 under the action of gravity. This design helps to effectively remove solid impurities and prevent them from accumulating on the filter screen 602 or clogging the mesh. As the impurities accumulate, they will continue to slide along the inclined surface of the filter screen 602 and eventually be discharged from the residue discharge port 604, thereby maintaining the continuous filtering effect of the filter screen 602 and the cleanliness of the filter material tank.

[0042] It should be noted that, for the above-mentioned embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should know that the utility model is not limited by the described action sequence, because according to the utility model, some steps may be performed in other sequences or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the utility model.
