Description

Technical Field

[0001] This invention relates to the field of drug-liquid separation, and in particular to a percolation extraction device for traditional Chinese medicine. Background Technology

[0002] In the preparation of traditional Chinese medicine, percolation is a commonly used method for preparing medicinal liquids. Percolation mainly involves placing the pulverized medicinal materials into a percolation device, then adding solvent from top to bottom. The solvent permeates through the medicinal materials and flows downwards, extracting the components of the medicinal materials. Finally, the extracted liquid is collected.

[0003] The relevant technology can be found in Chinese Patent No. CN206910849U, which discloses a herbal percolation device. Its key technical points are: it includes a primary percolation tank and a secondary percolation tank, both of which are frustum-shaped structures. The primary percolation tank is connected to the secondary percolation tank via a connecting pipe located on its side wall. A first herbal layer is located in the middle of the primary percolation tank, and a liquid extraction pipe is connected to its lower part. An infusion pipe is connected to the top of the primary percolation tank. A second herbal layer is located at the bottom of the secondary percolation tank, and a liquid outlet pipe is connected to its top. The connection point between the connecting pipe and the primary percolation tank is located at the bottom of the first herbal layer, and the connection point between the connecting pipe and the secondary percolation tank is located at the bottom of the second herbal layer.

[0004] Regarding the aforementioned technologies, when using a percolation tank to separate and extract the active ingredients from medicinal materials, the position of the medicinal materials in the percolation tank is relatively fixed. During long-term percolation, some active ingredients of the medicinal materials may not be completely separated and extracted, resulting in uneven and insufficient percolation of the medicinal materials, which may affect the quality of the extract. Summary of the Invention

[0005] In order to achieve a more uniform and thorough extraction of the effective components of medicinal materials, this application provides a percolation extraction device for traditional Chinese medicine.

[0006] This application provides a percolation extraction device for traditional Chinese medicine, which adopts the following technical solution:

[0007] A percolation extraction device for traditional Chinese medicine includes a percolation box with a medicine storage chamber. The percolation box includes a first side plate, a second side plate, and a drain pipe. The drain pipe is connected to the medicine storage chamber. A collection box is provided below the drain pipe. A stirring rod is rotatably connected between the first side plate and the second side plate. The stirring rod passes through the first side plate and is fixedly connected to a rotating rod. The rotating rod is fixedly connected to a variable-diameter rotating blade. The rotating blade is connected to a pressing component for pressing the medicinal materials.

[0008] By adopting the above technical solution, the pulverized medicinal materials are placed in the storage chamber, and the solvent permeates into the medicinal materials from top to bottom. The solvent extracts the effective components from the medicinal materials, and the extracted liquid flows into the collection tank through the drain pipe. The stirring rod is rotated periodically to agitate the medicinal materials in the permeation tank, changing their position. Then, the pressing component compresses the medicinal materials, allowing the solvent to better extract the effective components, thus improving the extraction effect and ensuring more uniform and thorough permeation.

[0009] Optionally, the diameter of the rotating blade gradually increases from the end away from the first side plate to the end closer to the first side plate. The pressing assembly includes a roller that cooperates with the rotating blade, a vertical rod that is rotatably connected to the roller, a horizontal plate that is vertically fixed to the vertical rod, and a pressing block that is fixedly connected to the horizontal plate. The length of the medicine storage chamber is greater than the length of the pressing block. The first side plate is connected to a limiting assembly that ensures the vertical movement of the vertical rod.

[0010] By adopting the above technical solution, the initial position roller is located at the end with the smallest diameter of the rotating blade, and the pressing block presses down on the medicinal materials in the storage chamber under its own weight; rotating the rotating rod can drive the stirring rod to rotate, turning the medicinal materials in the percolation box; at the same time, under the action of the limiting component, when the roller moves along the rotating blade to the end with the larger diameter, it drives the pressing block to move obliquely upward, so that the pressing block separates from the medicinal materials; when the roller moves along the rotating blade to the end with the smaller diameter, it drives the pressing block to move obliquely downward, thereby realizing the pressing block compacting the medicinal materials.

[0011] Optionally, the limiting component includes a sleeve fitted onto the upright and a crossbar fixed perpendicularly to the sleeve, the crossbar passing through the first side plate and slidably connected to the first side plate.

[0012] By adopting the above technical solution, the sleeve and crossbar can easily limit the position of the upright, so that the upright will not deviate when moving, which will help improve the stability of the pressing block when moving and ensure the pressing effect on the medicinal materials.

[0013] Optionally, a spring is fixed between the crossbar and the cross plate.

[0014] By adopting the above technical solution, the spring can easily pull the horizontal plate and the pressure block, further improving the pressing effect of the pressure block on the medicinal materials.

[0015] Optionally, the pressure block has several liquid guiding holes.

[0016] By adopting the above technical solution, the liquid guiding hole facilitates the addition of solvent from above the press block into the medicine storage cavity to contact the medicinal materials.

[0017] Optionally, a first sealing ring is provided between the stirring rod and the first side plate, and a second sealing ring is provided between the crossbar and the first side plate.

[0018] By adopting the above technical solution, the first sealing ring and the second sealing ring can improve the sealing performance, making it less likely for the solvent to leak out of the percolation tank.

[0019] Optionally, the stirring rod is fixedly connected with helical blades along its length.

[0020] By adopting the above technical solution, the spiral blades can easily increase the turning area and turning effect of the medicinal materials.

[0021] Optionally, the percolation box is provided with a bottom plate, and a partition that cooperates with the drug storage chamber is provided inside the percolation box. The partition has several filter holes, and a rotating door is rotatably connected to the partition. A filter layer is provided between the partition and the bottom plate.

[0022] By adopting the above technical solution, the filter layer facilitates the filtration of solid impurities extracted from medicinal materials, which helps to improve the purity of the extract that falls into the collection box.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The pulverized medicinal materials are placed in the storage chamber. The solvent seeps into the medicinal materials from top to bottom, extracting the active ingredients. The extracted liquid then flows into the collection tank through the drain pipe. The stirring rod is rotated periodically to agitate the medicinal materials in the percolation tank, changing their position. The materials are then compressed by the pressing assembly, allowing the solvent to better extract the active ingredients, thus improving the extraction efficiency and ensuring more uniform and thorough percolation.

[0025] 2. Initially, the roller is positioned at the end with the smallest diameter of the rotating blade. Under its own weight, the pressing block presses down on the medicinal materials in the storage chamber. Rotating the rotating rod drives the stirring rod to rotate, turning the medicinal materials in the percolation tank. Simultaneously, under the action of the limiting component, when the roller moves along the rotating blade towards the end with the larger diameter, it drives the pressing block to move obliquely upward, separating the pressing block from the medicinal materials. When the roller moves along the rotating blade towards the end with the smaller diameter, it drives the pressing block to move obliquely downward, thereby achieving the pressing block compacting the medicinal materials.

[0026] 3. The sleeve and crossbar facilitate the limiting of the upright, preventing the upright from tilting when moving, which in turn improves the stability of the pressing block during movement and ensures the compaction effect on the medicinal materials. Attached Figure Description

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] This application discloses a percolation extraction device for traditional Chinese medicine. Example

[0032] Reference Figure 1 A percolation extraction device for traditional Chinese medicine includes a percolation tank 1 with a storage chamber 2. In use, pulverized medicinal materials are placed in the storage chamber 2 of the percolation tank 1, and solvent is added. The solvent percolates into the medicinal materials from top to bottom and flows downwards under gravity, extracting the active ingredients from the medicinal materials. The percolation tank 1 includes a first side plate 11, a second side plate 12, and a drain pipe 13. The drain pipe 13 is equipped with a valve and is connected to the storage chamber 2. A collection box 4 is located below the drain pipe 13. When the operator opens the valve, the extracted liquid flows through the drain pipe 13 into the collection box 4.

[0033] Reference Figure 1 and Figure 2 A stirring rod 5 is rotatably connected between the first side plate 11 and the second side plate 12. After long-term percolation, the operator rotates the stirring rod 5, which rotates inside the percolation box 1. A spiral blade 52 is fixedly connected to the stirring rod 5 along its length. The stirring rod 5 and the spiral blade 52 then agitate the medicinal materials in the percolation box 1, changing the position of the medicinal materials. The spiral blade 52 can increase the agitation area and agitation effect of the stirring rod 5 on the medicinal materials.

[0034] Reference Figure 1 and Figure 2A stirring rod 5 is fixedly connected to a rotating rod 51 through the first side plate 11. A variable-diameter rotating blade 6 is fixedly connected to the rotating rod 51. The diameter of the rotating blade 6 gradually increases from the end furthest from the first side plate 11 to the end closest to the first side plate 11. A pressing assembly 7 is connected to the rotating blade 6. The pressing assembly 7 includes a roller 71 that cooperates with the rotating blade 6, a vertical rod 72 rotatably connected to the roller 71, a horizontal plate 73 vertically fixed to the upper end of the vertical rod 72, and a pressure block 74 fixedly connected to the horizontal plate 73. The length of the medicine storage chamber 2 is greater than the length of the pressure block 74. The roller 71 and the rotating blade 6 are always in contact. When the rotating rod 51 rotates, the rotating blade 6 rotates with the rotating rod 51, and consequently, the roller 71 moves with the rotating blade 6.

[0035] Reference Figure 1 and Figure 2 In the initial position, the roller 71 is located at the end with the smallest diameter of the rotating blade 6, and the pressing block 74 presses down on the medicinal materials in the storage chamber 2 under its own weight. When it is necessary to turn the medicinal materials in the percolation box 1 and re-press them, the operator rotates the rotating rod 51, which in turn drives the stirring rod 5 to rotate, turning the medicinal materials in the percolation box 1.

[0036] Reference Figure 1 and Figure 2 Meanwhile, the first side plate 11 is connected to a limiting component 111. The limiting component 111 includes a sleeve 1111 fitted onto the upright 72 and a crossbar 1112 fixed perpendicularly to the sleeve 1111. The crossbar 1112 passes through the first side plate 11 and is slidably connected to the first side plate 11. When the roller 71 moves with the rotating blade 6, and the roller 71 gradually moves towards the end with the larger diameter along the rotating blade 6, the roller 71 gradually moves closer to the first side plate 11. The sleeve 1111 is slidably connected to the upright 72. When the upright 72 moves obliquely upward, it pushes the crossbar 1112 to slide into the medicine storage cavity 2. The sleeve 1111 and the crossbar 1112 limit the upright 72, so that the upright 72 will not deviate during movement. Under the action of the limiting component 111, the roller 71 gradually rises in the height direction, thereby driving the pressing block 74 to move obliquely upward, so that the pressing block 74 separates from the medicine.

[0037] Reference Figure 1 and Figure 2After the medicinal materials are turned over, the operator reverses the rotating rod 51. The rotating rod 51 drives the rotating blade 6 to reverse, and the roller 71 gradually moves along the rotating blade 6 towards the smaller diameter end. When the upright rod 72 moves diagonally downward, it pushes the crossbar 1112 to slide outward from the medicine storage chamber 2. The roller 71 gradually moves away from the first side plate 11 and gradually decreases in height, thereby driving the pressing block 74 to move diagonally downward, thus bringing the pressing block 74 into contact with the medicinal materials and compressing them, allowing the solvent to better leach the effective components from the medicinal materials. Repeatedly turning and compressing the medicinal materials can improve the leaching effect of the effective components and make the medicinal materials permeate more evenly and fully.

[0038] Reference Figure 1 and Figure 2 A spring 8 is installed between the crossbar 1112 and the cross plate 73. The two ends of the spring 8 are fixedly connected to the crossbar 1112 and the cross plate 73, respectively. The spring 8 is always in a stretched state. When the pressure block 74 moves obliquely upwards, the extension of the spring 8 increases, making it easier for the spring 8 to pull the cross plate 73 and the pressure block 74, further improving the pressing effect of the pressure block 74 on the medicinal materials. When adding solvent into the percolation tank 1, the pressure block 74 has multiple liquid guiding holes 741. The solvent is poured in from above the pressure block 74, passing through the liquid guiding holes 741 and contacting the medicinal materials in the medicine storage chamber 2. A first sealing ring is installed between the stirring rod 5 and the first side plate 11, and a second sealing ring is installed between the crossbar 1112 and the first side plate 11. The first and second sealing rings are used to improve the sealing performance, making it difficult for the solvent to leak out of the percolation tank 1.

[0039] Reference Figure 1 and Figure 2 The percolation tank 1 has a bottom plate 14. Inside the percolation tank 1, a partition 15 is fixed to cooperate with the drug storage chamber 2. The partition 15 has multiple filter holes 151, through which the extracted liquid flows downward. A filter layer 153 is provided between the partition 15 and the bottom plate 14. The filter layer 153 can be made of cotton. The filter layer 153 facilitates the filtration of solid impurities extracted from the medicinal materials, improving the purity of the extract that falls into the collection tank 4. After long-term use, the filter layer 153 will accumulate a lot of impurities. The partition 15 is rotatably connected to a rotating door 152, which the operator can periodically open to replace the filter layer 153.

[0040] The implementation principle of the herbal percolation extraction device in this application embodiment is as follows: During use, the pulverized medicinal materials are placed in the storage chamber 2 of the percolation tank 1. Solvent is added to the percolation tank 1, and the solvent permeates into the medicinal materials from top to bottom, flowing downwards under gravity. The solvent extracts the effective components from the medicinal materials. The medicinal materials are then compressed by the pressing component 7. After extraction, the extract flows into the collection tank 4 through the drain pipe 13. After prolonged percolation, the operator rotates the stirring rod 5, which rotates within the percolation tank 1, thus agitating the medicinal materials and changing their position. The pressing component 7 then further compresses the medicinal materials, allowing the solvent to better extract the effective components. Repeated agitation and compression of the medicinal materials improves the extraction of effective components and ensures more uniform and thorough percolation.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
