Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine extraction technology, specifically a multifunctional extraction tank for traditional Chinese medicine. Background Technology

[0002] Herbal extractors are specialized equipment used to extract the active ingredients from traditional Chinese medicines. Their working principle is a simple decoction process, in which the herbs are soaked in water and heated with steam for a certain period of time to extract the active ingredients.

[0003] Traditional Chinese herbal medicine extraction tanks require stirring during the decoction process to prevent the accumulation of herbs and ensure sufficient contact between the herbs and water. This promotes the dissolution of the active ingredients in the herbs. However, the stirring range of traditional stirring rods (such as paddles) is limited, only acting on the lower part of the extraction tank. The inner wall, bottom corners, and top space of the extraction tank body easily form "stagnant zones"—herbal materials (especially blocky and fibrous herbs, such as roots, rhizomes, and bark) tend to accumulate and clump in these areas, preventing them from fully contacting the solvent (water, etc.). This obstructs the mass transfer path from the solvent to the surface of the herbal material, making it difficult for some of the active ingredients in the herbs to dissolve. Furthermore, due to the significant density differences among Chinese herbal medicines, a noticeable stratification phenomenon occurs during the extraction process. Some lighter herbs float on the water surface, while some heavier herbs sink. If the shearing and pushing forces of traditional stirring rods are insufficient, they cannot break up this stratification caused by density differences. As a result, the herbs that sink to the bottom accumulate, making it difficult for the solvent to penetrate into the herbs, while the herbs that float cannot be fully soaked. Consequently, the extraction degree of the same batch of herbs varies greatly, resulting in a low yield of effective components. Therefore, a multifunctional extraction tank for Chinese herbal medicines is proposed. Utility Model Content

[0004] Based on the above description, this utility model provides a multifunctional extraction tank for traditional Chinese medicine, which solves the technical problems pointed out in the background art.

The fixed cylinder includes a connecting section, a closed section and a filter hole section arranged sequentially from top to bottom. The side of the connecting section is provided with holes for the solvent to enter. The upper and lower ends of the closed section are respectively connected to the connecting section and the filter hole section. The side of the filter hole section is provided with filter holes. The extrusion mechanism includes a piston extruder and a drive assembly. The piston extruder is disposed inside the closed section and is sealed to the inner wall of the closed section. The piston extruder moves vertically under the action of the drive assembly to extrude the Chinese herbal medicine located inside the filter section.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the extraction tank body includes a tank body, the tank body includes a tank frame, the tank frame has an internal placement groove, the top of the tank frame has a tank cover, and the placement groove has an internal support plate.

[0008] Furthermore, the support plate includes a plate body, and the upper surface of the plate body is provided with a plurality of water passage holes, which are distributed in a ring at equal intervals.

[0009] Furthermore, the connecting section includes a fixed ring plate, which is located at the center of the lower surface of the can lid, and the lower surface of the fixed ring plate is provided with a plurality of connecting rods. The plurality of connecting rods are distributed in a ring at equal intervals along the outer edge of the inner ring of the fixed ring plate, and a flow hole is provided between two adjacent connecting rods.

[0010] Furthermore, the closed section includes a connecting cylinder disposed at the bottom end of the connecting rod, and the filter section includes a filter cylinder disposed at the bottom end of the connecting cylinder by a threaded connection. The filter cylinder has filter holes on its circumferential surface, and the bottom end of the filter cylinder is closed and in contact with the upper surface of the plate.

[0011] Furthermore, the driving assembly includes a limiting cylinder, which is located at the center of the upper surface of the can lid, and a main sealing ring is provided between the limiting cylinder and the can lid.

[0012] Furthermore, the limiting cylinder includes a hollow cylinder body, and multiple limiting grooves are provided on the circumferential surface inside the hollow cylinder body. The multiple limiting grooves are distributed in a ring at equal intervals, and a cylinder cover is provided on the top of the hollow cylinder body.

[0013] Furthermore, a motor is provided at the top of the cylinder cover, and a threaded vertical rod is provided at the output shaft of the motor. The threaded vertical rod passes through the cylinder cover, the limiting cylinder and the can cover from top to bottom and extends into the interior of the can body.

[0014] Furthermore, the piston extrusion component includes a vertical rod, which is sleeved outside the threaded vertical rod, and a threaded blind hole is provided on the upper surface of the vertical rod. The threaded vertical rod is threadedly connected to the threaded blind hole.

The outer ring of the O-ring is tightly fitted with the inner wall of the connecting cylinder to seal the gap between the piston block and the inner wall of the connecting cylinder.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. This multifunctional extraction tank for Chinese herbal medicines, by setting up the extraction tank body, fixed cylinder and extrusion mechanism and other components, through the cooperation between the fixed cylinder and the extrusion mechanism, allows the Chinese herbal medicines placed inside the fixed cylinder to be squeezed downward by the extrusion mechanism during the decoction process. On the one hand, it can confine the Chinese herbal medicines inside the fixed cylinder, which can avoid the situation where the Chinese herbal medicines are not completely immersed in the solvent due to stratification. On the other hand, after the Chinese herbal medicines are squeezed, their effective components are more easily extracted.

[0017] 2. This multifunctional extraction tank for traditional Chinese medicine uses a fixed cylinder and a pressing mechanism. When the pressing mechanism moves vertically, it drives the piston pressing component to move as well. During this process, the space inside the filter cylinder changes. When the space becomes smaller, that is, when the piston pressing component moves downward, the traditional Chinese medicine is compressed, and the solvent inside the filter cylinder is discharged to the outside of the filter cylinder. Conversely, the solvent outside the filter cylinder is drawn into the filter cylinder to flush the traditional Chinese medicine, thereby allowing the traditional Chinese medicine to come into more thorough contact with the solvent and ensuring that its effective components are more easily extracted.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1 , Figure 2 and Figure 4 A multifunctional extraction tank for traditional Chinese medicine includes: an extraction tank body, a fixed cylinder 8, and a squeezing mechanism; The extraction tank body includes a tank body 1, the tank body 1 includes a tank body 11, the tank body 11 has a placement groove 12 inside, the tank body 11 has a tank cover 2 on top, and the placement groove 12 has a support plate 9 inside.

[0022] Based on the above, the main body of the extraction tank is the extraction tank in the prior art, which has the ability to heat the solvent inside it. That is, the outer layer of the tank body 11 is wrapped with a heating jacket, which can be filled with steam or heat transfer oil. The heating jacket is the prior art and is not shown in the figure. A liquid outlet is provided at the bottom of the tank body 11. The placement groove 12 is provided so that the support plate 9 can be placed in it to support the fixed cylinder 8.

[0023] like Figure 2 and Figure 9 As shown, the support plate 9 includes a plate body 91, and the upper surface of the plate body 91 is provided with a plurality of water passage holes 92, which are distributed in a ring at equal intervals.

[0024] Based on the above, the support plate 9 serves to support the fixed cylinder 8, and the water passage hole 92 allows the solvent to flow through the support plate 9.

[0025] like Figure 2 , Figure 3As shown, the fixed cylinder 8 is disposed inside the body of the extraction tank and connected to the lower surface of the tank cover 2. The fixed cylinder 8 includes a connecting section, a closed section and a filter hole section arranged sequentially from top to bottom. The side of the connecting section is provided with holes for the solvent to enter. The upper and lower ends of the closed section are respectively connected to the connecting section and the filter hole section. The side of the filter hole section is provided with filter holes 86.

[0026] like Figure 7 and Figure 8 As shown, the connecting section includes a fixed ring plate 81, which is located at the center of the lower surface of the can lid 2. The lower surface of the fixed ring plate 81 is provided with a plurality of connecting rods 82, which are distributed in a ring at equal intervals along the outer edge of the inner ring of the fixed ring plate 81. A flow hole 83 is provided between two adjacent connecting rods 82.

[0027] The closed section includes a connecting cylinder 84, which is disposed at the bottom end of the connecting rod 82. The filter section includes a filter cylinder 85, which is disposed at the bottom end of the connecting cylinder 84 by a threaded connection. The filter cylinder 85 has filter holes 86 on its circumferential surface, and the bottom end of the filter cylinder 85 is closed and in contact with the upper surface of the plate 91.

[0028] Based on the above, the fixed cylinder 8 serves to restrict the Chinese herbal medicine, allowing it to be placed inside the filter cylinder 85. At this time, the Chinese herbal medicine can still come into contact with the solvent. Furthermore, the connecting cylinder 84 can cooperate with the piston extrusion component 7, so that the fixed cylinder 8 is separated by the piston extrusion component 7, that is, divided into the upper and lower parts of the piston extrusion component 7. The piston extrusion component 7 is located inside the closed section, with the upper part being the connecting section and the lower part being the filter hole section.

[0029] The connecting section, which consists of the connecting rod 82 and the flow hole 83, allows the solvent to enter when the piston extrusion member 7 moves downward, and the solvent inside the filter hole section is discharged. Conversely, the solvent inside the connecting section is discharged, and the solvent outside the filter hole section enters it. The filter holes 86 on the surface of the filter hole section allow the solvent to come into contact with the Chinese herbal medicine, so that the Chinese herbal medicine can still be decocted during the process of heating the solvent.

[0030] like Figures 1-4 As shown, the driving assembly includes a limiting cylinder 3, which is located at the center of the upper surface of the can lid 2. A main sealing ring is provided between the limiting cylinder 3 and the can lid 2. The limiting cylinder 3 includes a hollow cylinder body 31. Multiple limiting grooves 32 are provided on the circumferential surface inside the hollow cylinder body 31. The multiple limiting grooves 32 are distributed in a ring at equal intervals. A can lid 4 is provided on the top of the hollow cylinder body 31.

[0031] A motor 5, model ATO130SY-M10015, is provided on the top of the cylinder cover 4. A threaded vertical rod 6 is provided at the output shaft of the motor 5. The threaded vertical rod 6 passes through the cylinder cover 4, the limiting cylinder 3 and the can cover 2 from top to bottom and extends into the interior of the can body 1.

[0032] Based on the above, the motor 5 drives the threaded vertical rod 6 to rotate, and under the action of threaded transmission, it drives the piston extrusion part 7 to move vertically. The limiting cylinder 3 and the cylinder cover 4 cooperate with each other to support the motor 5. In addition, the setting of the main sealing ring ensures that the piston extrusion part 7 remains sealed when it moves downward, thus preventing solvent leakage.

[0033] like Figure 2 , Figure 3 as well as Figure 6 As shown, the piston extrusion component 7 includes a vertical rod 71, which is sleeved on the outside of the threaded vertical rod 6, and a threaded blind hole 72 is provided on the upper surface of the vertical rod 71. The threaded vertical rod 6 is threadedly connected to the threaded blind hole 72. A plurality of limiting blocks 73 are provided on the circumferential surface of the vertical rod 71, and the limiting blocks 73 extend into the interior of the limiting groove 32. The circumferential surface of the vertical rod 71 is tightly fitted with the inner ring of the main sealing ring.

[0034] A piston block 74 is provided at the bottom end of the vertical rod 71. The piston block 74 is located inside the connecting cylinder 84. An annular groove 75 is provided on the circumferential surface of the piston block 74. An O-ring 76 is provided inside the annular groove 75. The outer ring of the O-ring 76 is tightly fitted with the inner wall of the connecting cylinder 84 to seal the gap between the piston block 74 and the inner wall of the connecting cylinder 84.

[0035] Based on the above, the piston block 74 and the O-ring seal 76 cooperate with each other so that when the piston block 74 moves downward, it can push the solvent inside the filter cartridge 85, causing this part of the solvent to be squeezed out, while the solvent outside the connecting cylinder 84 is sucked into the upper part of the connecting cylinder 84. Conversely, the solvent is sucked into the interior of the filter cartridge 85, while the solvent above the connecting cylinder 84 is squeezed out.

[0036] During the above process, the limiting block 73 and the limiting groove 32 cooperate with each other, so that the piston extrusion part 7 is restricted to only vertical movement. The threaded blind hole 72 and the threaded vertical rod 6 cooperate with each other, so that the piston extrusion part 7 moves vertically under the action of threaded transmission, that is, moves downward or upward.

[0037] This utility model's multifunctional extraction tank for traditional Chinese medicine achieves efficient extraction of active ingredients from medicinal materials through the synergistic effect of "directional constraint, dynamic extrusion, and solvent circulation." The specific working process is as follows: Medicinal herb filling and equipment sealing: Open the canister lid 2 and load the pre-treated Chinese herbal medicines (lumps, fibers, or flowers and leaves) into the filter cartridge 85, ensuring that the amount of herbs does not exceed 80% of the volume of the filter cartridge 85 (leaving room for compression); close the canister lid 2 and lock it with the quick-opening flange to ensure a seal between the canister lid 2 and the canister body 11, and between the threaded vertical rod 6 and the canister lid 2; inject solvent (water, ethanol, etc.) into the canister body 1. The solvent enters the lower part of the canister body 1 through the water passage 92 of the support plate 9, and at the same time enters the upper space of the connecting cylinder 84 through the flow hole 83 of the connecting section of the fixed cylinder 8, until the solvent level covers the top of the fixed cylinder 8, completing the preparation before extraction; Heating and extrusion extraction: The heating jacket on the outside of tank 1 is activated to raise the solvent temperature to the set extraction temperature; at the same time, motor 5 is started, and motor 5 drives the threaded vertical rod 6 to rotate clockwise. Under the constraint of the threaded transmission and the limiting block 73-limiting groove 32, the vertical rod 71 drives the piston block 74 to move downward along the inner wall of the connecting cylinder 84. When the piston block 74 moves downward, the internal volume of the filter cylinder 85 decreases and the pressure increases, forcing the solvent inside the filter cylinder 85 to be quickly discharged into the inner cavity of the tank 1 through the filter hole 86. During this process, the solvent exerts a "squeezing and scouring" effect on the medicinal materials, breaking the concentration polarization layer on the surface of the medicinal materials and promoting the migration of active ingredients into the solvent. When the piston block 74 moves to the vicinity of the top of the filter cylinder 85, the motor 5 rotates in the opposite direction, and the threaded vertical rod 6 drives the piston block 74 to move upward. The internal space of the filter cylinder 85 increases, forming a negative pressure. The solvent in the inner cavity of the tank 1 is drawn back into the filter cylinder 85 through the filter hole 86 and comes into full contact with the medicinal materials again, realizing the circulation and renewal of the solvent. Repeat the above process of "downward squeezing - upward suction". Under the synergistic effect of heating and dynamic squeezing, the effective components of the medicinal materials continue to dissolve into the solvent. Post-extraction processing and equipment cleaning: After extraction is complete, turn off the heating and motor 5, and discharge the extract through the outlet at the bottom of the tank 1. The extract is pre-filtered by the pre-filter and then enters the subsequent purification process. Open the tank cover 2, unscrew the filter cartridge 85 (threaded connection), and pour out the residue inside the filter cartridge 85 to complete the separation of the medicinal material and the residue. Clean the filter cartridge 85, piston block 74 and other parts (high pressure water gun can be used for rinsing). After cleaning, reassemble the parts and the next batch of extraction can be carried out.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
