Description

Technical Field

[0001] The invention belongs to the technical field of traditional Chinese medicine extraction, and more specifically, relates to a traditional Chinese medicine distillation and refining device with a residue filtering function. Background Art

[0002] As a core technology in traditional pharmaceutical manufacturing, Chinese herbal medicine (TCM) distillation and extraction plays a vital role in the modern production of TCM and is widely used in the extraction of raw materials for TCM preparations, health supplements, and cosmetics. TCM distillation and extraction involves heating the medicinal materials to release the active ingredients in the steam, which are then collected and separated through condensation for purification. To ensure extraction efficiency and product quality, TCM distillation and extraction equipment is often used. These equipment effectively mix the medicinal materials with the solvent, distill the components, and collect the extract. Furthermore, during the distillation and extraction process, the medicinal materials must be stirred to ensure uniform heating and efficient mass transfer to prevent sedimentation and coking and to promote the full dissolution of the active ingredients. However, traditional TCM distillation and extraction equipment uses mechanical stirring to mix the medicinal materials. The stirring paddles, exposed to long-term contact with the hot liquid, are susceptible to wear, and there are internal dead zones within the equipment, resulting in uneven mixing of the medicinal materials and the solvent, preventing the effective ingredients from being fully released. This ultimately leads to low extraction efficiency and insufficient raw material utilization. Furthermore, the equipment lacks a residue filtration function, causing some liquid to be discharged with the residue, resulting in wasteful extraction. Summary of the Invention

[0016] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention. Example:

[0017] like Figures 1 to 9 As shown, the present invention provides a Chinese medicine distillation and refining device with a residue filtering function, with a support plate 11 as the basic bearing structure, providing a stable support platform for the entire device. The distillation kettle is installed above the support plate 11 as a core component and is a key place for the distillation operation of Chinese medicine. The through hole opened at the bottom of the distillation kettle forms a specific discharge channel, which provides a path for the discharge of residue after the distillation is completed. At the same time, a feed pipe is provided on the distillation kettle, through which the Chinese medicine raw materials and solvents can be transported to the distillation chamber in proportion, providing a material basis for the distillation and refining process. The rotating bottom plate 12 located in the discharge channel can be rotated under the action of a driving device. When the residue needs to be discharged, the bottom plate 12 rotates so that the residue can fall smoothly through the discharge channel; during the distillation process, the bottom plate 12 remains closed to prevent liquid leakage and ensure that the distillation operation is carried out normally in a confined space.

[0018] The support plate 11 is divided into two areas: the distillation section and the filtration section. The still is located within the distillation section and is responsible for extracting the active ingredients in the traditional Chinese medicine distillation process. A filter tank 21 is positioned above the support plate 11. The filter screen 22 within it intercepts falling residue, achieving a preliminary separation of solids and liquids and reducing the amount of residue in the liquid. A slide rail assembly runs through the distillation and filtration sections, providing a movement track for the filter tank 21. The filter tank 21 is mounted on the slide rail assembly and can move along the track between the distillation and filtration sections. The slide rail assembly is a common method of movement that uses a slide rail and an electric slide, but other movement methods are also possible. When distillation is complete, the filter tank 21 slides below the still to collect the residue; after filtration, it can be moved back to the filtration section. The extrusion assembly within the filtration section is used to further process the residue within the filter tank 21. By squeezing, the remaining liquid in the residue is squeezed out, improving the liquid recovery rate and also making the residue drier for subsequent cleaning.

[0019] The stirring assembly and extraction assembly above the support plate 11 perform different yet closely related functions. The storage tank 31 in the stirring assembly is used to store magnetic fluid, a special working medium that plays a vital role in the traditional Chinese medicine distillation process. The storage tank 31 is connected to the still via a water pump, which transports the magnetic fluid from the storage tank 31 to the still. Multiple heating modules 32 arranged around the still provide the heat required for the distillation process, heating the raw Chinese medicinal materials and evaporating their active ingredients. Multiple sets of arc-shaped electromagnets 33 surround the still. When energized, these arc-shaped electromagnets 33 generate magnetic fields that interact with the magnetic fluid entering the still, driving the fluid's movement and thereby stirring and mixing the raw Chinese medicinal materials and solvent within the still, promoting the effective extraction of the active ingredients. The still is connected to the extraction assembly via an air duct. The steam generated during the distillation process carries the active ingredients through the duct into the extraction assembly for subsequent condensation and collection. The entire device is controlled and operated by an external control system.

[0020] like Figure 2 、 Figures 4 to 6 As shown, the distillation kettle is composed of a tank body 41, a top cover 42 and a bottom cover 43. The three are connected to each other to form a closed distillation chamber. This space is where Chinese medicinal materials and solvents are placed and distillation operations are performed. The support frame 13 on the support plate 11 provides support for the tank body 41. After the tank body 41 is inserted into the support frame 13, it is fixed by multiple groups of bolts to ensure that it will not shake or shift during the distillation process. A through hole is set on the top cover 42 to form an initial channel for material discharge. The two groups of connecting plates 44 on the top cover 42 cooperate with the connecting columns on both sides of the bottom plate 12, so that the bottom plate 12 can rotate relative to the bottom cover 43. The first motor is installed on one side of one group of connecting plates 44, and its shaft end is connected to the connecting column. When working, it drives the bottom plate 12 to rotate and controls the opening and closing of the discharge channel, making it convenient to discharge the residue after the distillation is completed and keep the distillation chamber closed during the distillation process.

[0021] The mounting groove 45 on the tank body 41 is used to accommodate multiple groups of arc-shaped electromagnets 33. These arc-shaped electromagnets 33 are connected end to end to form an annular electromagnet sleeve outside the tank body 41. The arc-shaped electromagnet 33 is located below the heating module 32 and close to the bottom plate 12. When energized, it generates a magnetic field and interacts with the magnetic fluid in the distillation chamber. When the magnetic fluid enters the distillation chamber, it flows under the action of the magnetic field of the arc-shaped electromagnet 33, driving the Chinese medicinal materials and solvent in the chamber to mix, and promoting the extraction of effective ingredients from the medicinal materials. The mounting slots 46 on both sides of the bottom cover 43 cooperate with the heat conducting plate 47 to form a mounting cavity, in which the heating plate 48 is placed. The heat generated by the heating plate 48 is evenly transferred to the bottom cover 43 through the heat conducting plate 47, thereby heating the material in the distillation chamber, providing heat energy for the distillation process, evaporating the solvent, and carrying the effective ingredients to form steam.

[0022] like Figure 2 、 Figure 3 As shown, the mounting bracket 51 of the extrusion assembly is fixed to the filtration section of the support plate 11, providing a mounting base for other components. An electric cylinder 52 is mounted on the mounting bracket 51 and powered by telescopic movement. During the extrusion operation, the filter tank 21 is moved from the distillation section to the filter section below the electric cylinder 52 via the slide rail assembly. The mounting cover 53 is connected to the shaft end of the electric cylinder 52 and moves with the electric cylinder 52. A second motor is mounted within the mounting cover 53, driving the extrusion block 54 to rotate. The diameter of the extrusion block 54 is smaller than the internal diameter of the filter tank 21. After the filter tank 21 receives the residue, the electric cylinder 52 pushes the mounting cover 53 and the extrusion block 54 downward. Simultaneously, the second motor drives the extrusion block 54 to rotate, squeezing the residue within the filter tank 21. The extrusion process squeezes any remaining liquid from the residue through the filter screen 22, improving liquid recovery and reducing liquid loss with the residue. After filtration is complete, an external water pump is activated to return the liquid in the filter tank 21, filtered through the filter screen 22, to the distillation kettle. These recovered liquids can be distilled and refined again to make full use of the effective ingredients that may remain in them and improve the utilization rate of raw materials.

[0023] like Figure 2 、 Figures 7 to 9 As shown, in the extraction assembly, the mounting platform 63 on the support plate 11 is used to fix the condenser 61, and the assembly groove on the top cover 42 is used to install the collecting funnel 49. The collecting funnel 49 is placed upside down, and its opening is docked with the assembly groove, and is connected to the inlet of the condenser 61 through the air duct. The steam generated during the distillation process carries the effective ingredients of traditional Chinese medicine, enters the air duct through the collecting funnel 49, and then flows into the condenser 61. The condenser 61 cools the steam and condenses it into liquid. The extraction tank 62 is mounted on the support plate 11 and is located below the condenser 61, and receives the condensate flowing out of the condenser 61 through the air duct. The extraction tank 62 is used to store and further process the condensed extract.

[0024] The bottom of extraction tank 62 is connected to base tank 64, and the two together form the main chamber. The internal diameter of extraction tank 62 is smaller than that of base tank 64. A partition within the tank divides the main chamber into two layers: a first extraction chamber and a second extraction chamber. Multiple sets of liquid holes 65 on the partition allow the first and second extraction chambers to communicate with each other, allowing condensate to flow into the first extraction chamber before flowing through liquid holes 65 into the second extraction chamber. An access slot on one side of base tank 64 is used to mount a collection box 66, which is located in the second extraction chamber and is used to collect substances that need to be separated during the extraction liquid processing process.

[0025] The positioning groove in the bottom tank 64 is used to fix the electromagnetic plate 67, and the magnetic plate 68 at the bottom of the collection box 66 can attract the electromagnetic plate 67. When it is necessary to separate certain substances in the extract, the electromagnetic plate 67 is energized to generate magnetism, and the magnetic plate 68 at the bottom of the collection box 66 adsorbs the magnetic fluid in the extract to the bottom of the collection box 66 under the action of magnetic force, thereby achieving the separation of the magnetic fluid and the extract. The extraction tank 62 is connected to other external equipment through a water pump, and the extract in the first extraction chamber can be transported out of the device. The liquid flowing into the second extraction chamber through the partition liquid hole 65, the residual magnetic fluid therein is also adsorbed and collected under the magnetic force of the electromagnetic plate 67 and the magnetic plate 68, ensuring that the magnetic fluid in the extract is fully separated, facilitating the subsequent purification of the extract and the recycling and reuse of the magnetic fluid.

[0026] Multiple sets of ultrasonic transducers 23 are distributed around the outer wall of the tank 41. An ultrasonic generator 14, housed in an equipment box on one side of the support frame 13, is connected to the ultrasonic transducers 23 via wires. The ultrasonic generator 23 can be a Fischer FUS-3000 ultrasonic generator. The ultrasonic generator 14 generates an electrical signal, which is transmitted via wires to the ultrasonic transducer 23. The ultrasonic transducer 23 converts the electrical signal into ultrasonic energy, which is then transmitted into the distillation chamber. The ultrasonic transducer 23 can be an NTK-28K-1500W ultrasonic transducer. During the distillation process, ultrasonic waves act on the Chinese medicinal materials and solvent, creating a cavitation effect that disrupts the cellular structure of the medicinal materials and accelerates the dissolution of the active ingredients. The ultrasonic vibrations also promote mixing of the materials, working in conjunction with the magnetic fluid stirring and heating processes to improve distillation efficiency.

[0027] The specific usage and function of this embodiment are as follows: During use, the Chinese medicinal material and solvent are first delivered in proportion to each other through a feed pipe into the distillation chamber of the still. Next, the water pump adjacent to the storage tank 31 is activated to inject magnetic fluid into the still. Simultaneously, the multiple heating modules 32 and arc-shaped electromagnets 33 are activated. The magnetic fluid stirs the material under the influence of the magnetic field, while the heating modules 32 provide the heat required for distillation. The steam generated by distillation flows through a collection funnel 49 and an air duct into a condenser 61, where it condenses and flows into an extraction tank 62.

[0028] After distillation is complete, the first motor drives the bottom plate 12 to rotate, and the residue falls through the discharge channel into the filter tank 21, which slides below the distillation kettle. The filter screen 22 initially intercepts the residue. Subsequently, the filter tank 21 slides back to the filtration section, and the electric cylinder 52 pushes the extrusion block 54 to squeeze the residue. The filtered liquid is then pumped back to the distillation kettle for further refining. In the extraction tank 62, when the magnetic fluid needs to be separated, the electromagnetic plate 67 is energized, attracting the magnetic plate 68 at the bottom of the collection box 66, adsorbing the magnetic fluid to the collection box 66. The separated extract is then pumped out of the device from the first extraction chamber via the water pump, completing the entire Chinese medicine distillation and refining process.

[0029] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
