Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine extraction, and in particular to a device for recovering extractants from traditional Chinese medicine extracts. Background Technology

[0002] Traditional Chinese medicine extract extraction is a key process that uses solvents such as water and ethanol, along with modern technology, to extract Chinese medicinal materials at high temperatures. This process aims to maximize the retention of medicinal components, ensure product safety, stability, and high efficiency, and provide high-quality raw materials for Chinese medicine preparations and health products.

[0003] In the process of extracting traditional Chinese medicine using high-temperature extraction technology, high-temperature gas is continuously emitted, which can easily carry away some volatile extracts, resulting in a reduced recovery rate of effective components, insufficient extraction, and material loss. At the same time, relying solely on a single stirring method makes it difficult to ensure that the medicinal materials fully and evenly contact the solvent and are heated, resulting in significant differences in local extraction, which affects the uniformity of the overall extraction process and the quality of the final extracted product. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for recovering extractants from traditional Chinese medicine extracts. This device reduces the loss of active ingredients, improves recovery efficiency and material utilization, and ensures the consistency of the extraction process and the stability of the quality of the extracted products.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An extraction heating tank for extraction stirring has a recovery frame fixedly connected to its right side, a transfer pipe fixedly connected to its top, a condenser fixedly connected to the lower right side of the transfer pipe, multiple downward flow slots at the bottom of the condenser, a collection frame fixedly connected to the middle of the bottom of the recovery frame, a gas exhaust sleeve fixedly connected to the right side of the top of the recovery frame, an air inlet sleeve on the right side of the recovery frame, a cooling fan fixedly connected inside the air inlet sleeve, and a heat equalization component installed inside the recovery frame to reduce the temperature of the condenser.

A stirring sleeve is rotatably connected to the outer circumference of the stirring sleeve. Multiple inner stirring rods are fixedly connected to the outer circumference of the stirring sleeve. A speed-regulating rotation component is installed at the bottom of the extraction heating tank to achieve different rotational speeds for the peripheral stirring rods and the inner stirring rods.

[0009] Furthermore, the speed-regulating rotation assembly includes a driven large gear located on the lower outer side of the stirring sleeve, a driven small gear fixedly connected to the lower outer side of the stirring shaft, a mounting bracket fixedly connected to the front bottom of the extraction heating tank, a rotating stem rotatably connected inside the mounting bracket, a driving small gear fixedly connected to the upper outer side of the rotating stem, a driving large gear fixedly connected to the lower outer side of the rotating stem, a drive motor fixedly connected to the bottom of the mounting bracket, and the drive end of the drive motor fixedly connected to the bottom of the rotating stem.

[0010] Furthermore, the driven large gear and the driving small gear are meshed together, and the driving large gear and the driven small gear are meshed together.

[0011] Furthermore, the heat dissipation assembly includes cooling copper plates fixed on both sides of the condenser tube. The right side of the cooling copper plate is fixedly connected to the inside of the recycling frame, and multiple cooling copper tubes are fixedly connected to the outer side of the cooling copper plate.

[0012] Furthermore, multiple air inlet covers are fixedly connected to the left side of the air inlet sleeve, and the outside of the air inlet covers is fixedly connected to the right side of the recycling frame. The upper side of the cooling copper tube penetrates the inside of the air inlet covers.

[0013] Furthermore, traction blocks are fixedly connected to both sides of the bottom end of the recycling frame.

[0014] Furthermore, a fixed frame is fixedly connected to the top of the inner part of the extraction heating tank, and the external part of the stirring shaft is rotatably connected to the inside of the fixed frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the synergistic effect of the condenser, the heat equalization component and the recovery frame, the high-temperature volatile gas generated during extraction can be fully and uniformly cooled, so that the entrained extractant vapor can be condensed and recovered, reducing the loss of effective components and improving recovery efficiency and material utilization.

[0017] 2. In this utility model, a dual-shaft differential stirring structure is adopted. By having two sets of stirring rods running at different speeds, the mixing intensity and uniformity of the material and solvent in the tank are greatly improved, avoiding local under-extraction or overheating, thereby ensuring the consistency of the extraction process and the stability of the quality of the extracted product.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a traditional Chinese medicine extract recovery device, comprising an extraction heating tank 1 for extraction stirring, a recovery frame 2 fixedly connected to the right side of the extraction heating tank 1, a transmission pipe 8 fixedly connected to the top of the extraction heating tank 1, a condenser pipe 21 fixedly connected to the lower right side of the transmission pipe 8, a plurality of downward flow slots 23 opened at the bottom end of the condenser pipe 21, a collection frame 9 fixedly connected to the middle of the bottom end of the recovery frame 2, a gas exhaust sleeve 3 fixedly connected to the right side of the top of the recovery frame 2, and an air inlet sleeve 4 provided on the right side of the recovery frame 2. The air inlet sleeve 4 is internally fixedly connected to... A cooling fan 5 is connected to the inside of the recovery frame 2, and a heat spreader is installed inside the frame to reduce the temperature of the condenser tube 21. The heat spreader includes a cooling copper plate 20 fixed on both sides of the condenser tube 21. The right side of the cooling copper plate 20 is fixedly connected to the inside of the recovery frame 2. Multiple cooling copper pipes 6 are fixedly connected to the outside of the cooling copper plate 20. Multiple air inlet hoods 22 are fixedly connected to the left side of the air inlet sleeve 4. The outside of the air inlet hood 22 is fixedly connected to the right side of the recovery frame 2. The upper side of the cooling copper pipe 6 penetrates the inside of the air inlet hood 22. Traction blocks 19 are fixedly connected to both sides of the bottom end of the recovery frame 2.

[0027] In the high-temperature extraction process of traditional Chinese medicine extract, the medicinal materials and solvent in the extraction heating tank 1 undergo an extraction reaction under heating conditions. The high-temperature gas produced carries some volatile extracts and enters the recovery frame 2 through the transfer pipe 8. The gas is cooled in the recovery frame by the condenser pipe 21. The condensed liquid flows into the collection frame 9 along the downstream outlet 23, thereby realizing the recovery of the extractant. In order to further improve the condensation efficiency, the cooling copper plate 20 and the cooling copper pipe 6 in the heat spreader work together to introduce cooling air with the help of the cooling fan 5 set in the air inlet sleeve 4 to uniformly cool the condenser pipe 21 and avoid the condensation effect being affected by excessively high local temperature.

[0028] Reference Figure 2 , Figure 3 and Figure 5A stirring shaft 14 is used for stirring inside the extraction heating tank 1. Multiple peripheral stirring rods 13 are fixedly connected to the outer circumference of the stirring shaft 14. A stirring sleeve 16 is rotatably connected to the outer circumference of the stirring sleeve 16. Multiple inner stirring rods 15 are fixedly connected to the outer circumference of the stirring sleeve 16. A speed-regulating rotation assembly is installed at the bottom of the extraction heating tank 1 to achieve different rotational speeds between the peripheral stirring rods 13 and the inner stirring rods 15. The speed-regulating rotation assembly includes a driven large gear 24 located on the lower outer side of the stirring sleeve 16, a driven small gear 17 fixedly connected to the lower outer side of the stirring shaft 14, and a gear fixedly connected to the front of the bottom of the extraction heating tank 1. There is a mounting frame 7, and a rotating shaft 10 is rotatably connected inside the mounting frame 7. A drive pinion 25 is fixedly connected to the upper side of the rotating shaft 10, and a drive gear 11 is fixedly connected to the lower side of the rotating shaft 10. A drive motor 12 is fixedly connected to the bottom end of the mounting frame 7, and the drive end of the drive motor 12 is fixedly connected to the bottom end of the rotating shaft 10. The driven gear 24 and the drive pinion 25 are meshed together, and the drive gear 11 and the driven pinion 17 are meshed together. A fixed frame 18 is fixedly connected to the top of the interior of the extraction heating tank 1, and the stirring shaft 14 is rotatably connected to the interior of the fixed frame 18.

[0029] The stirring system is driven by a speed-regulating rotary assembly. The drive motor 12 drives the drive gear 11 and drive gear 25 to rotate via the rotating shaft 10. Then, through gear meshing transmission, it sequentially drives the driven gear 17 and driven gear 24, causing the stirring shaft 14 and the stirring sleeve 16 to rotate at different speeds. This differential stirring mechanism drives the outer stirring rod 13 and the inner stirring rod 15 to form differential stirring motion, effectively enhancing the mixing uniformity of the material and solvent in the tank, thereby improving the extraction efficiency and the extraction rate of the target components.

[0030] Working Principle: During the high-temperature extraction of traditional Chinese medicine extracts, the medicinal materials and solvent in the extraction heating tank 1 undergo an extraction reaction under heating conditions. The generated high-temperature gas, carrying some volatile extracts, enters the recovery frame 2 through the transfer pipe 8. The gas is cooled by the condenser pipe 21 in the recovery frame 2, and the condensed liquid flows into the collection frame 9 through the downstream outlet 23, realizing the recovery of the extractant. To further improve the condensation efficiency, the cooling copper plate 20 and cooling copper pipe 6 in the heat spreader assembly work together, and cooling air is introduced through the cooling fan 5 in the air inlet jacket 4 to cool the extractant. The condenser tube 21 provides uniform cooling to prevent incomplete condensation caused by excessively high local temperatures. The stirring system is driven by a speed-regulating rotating component. The drive motor 12 drives the drive gear 11 and drive gear 25 to rotate via the rotating shaft 10. In turn, the drive gear 17 and drive gear 24 are driven by gear meshing, causing the stirring shaft 14 and stirring sleeve 16 to rotate at different speeds. This causes the outer stirring rod 13 and the inner stirring rod 15 to form differential stirring, which enhances the uniformity of mixing between the material and the solvent in the tank and improves the extraction efficiency and component extraction rate.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
