DETAILED DESCRIPTION

[0027] In the following, the utility model is further described in combination with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.

[0028] Please combine Figures 1-5 The effective component extraction device of traditional Chinese medicine rhizoma polygonati of the embodiment comprises a support frame 1, an extraction cylinder 2 is fixedly connected to the inner side of the support frame 1, water or alcohol solvent is conveniently introduced into the extraction cylinder 2, therefore a liquid inlet pipe 21 is connected to the side wall of the extraction cylinder 2, and a liquid outlet pipe 22 is additionally installed at the lower bottom of the extraction cylinder 2, and a valve is installed on the liquid outlet pipe 22 to control the opening and closing of the liquid outlet pipe 22.

[0029] In order to increase the contact area between the solvent and the rhizoma polygonati during extraction, the rhizoma polygonati can be cut into small pieces or even powder. In order to prevent impurities or fine rhizoma polygonati powder from flowing out when the outlet pipe 22 is opened, a filter screen 25 is installed inside the extraction cylinder 2 above the outlet pipe 22.

[0030] The heating can increase the thermal motion speed of molecules, increase the solubility and diffusion rate of the effective components in the solvent. Therefore, a metal heating ring 24 is installed on the inner wall of the extraction cylinder 2, and the heating ring 24 is connected with an external power supply.

[0031] In addition, in order to facilitate the loading of the rhizoma polygonati, a cartridge 7 is provided, and a plurality of water permeable holes 71 are formed in the side wall and the bottom of the cartridge 7, and the extraction solvent can pass through the water permeable holes 71. In order to install the cartridge 7, a positioning groove 23 is formed in the inner side wall of the extraction cylinder 2, and a positioning strip 72 is fixedly connected to the outer side wall of the cartridge 7, and the positioning strip 72 is clamped in the positioning groove 23 during installation. The cartridge 7 can be installed at a specified position. In actual use, a ring plate (not shown in the figure) can also be arranged on the inner side wall of the extraction cylinder 2 below the cartridge 7, for supporting the cartridge 7.

[0032] In addition, a lifting platform 3 that can move up and down is also arranged on the support frame 1. In order to control the up and down movement of the lifting platform 3, a threaded rod 4 and three guide rods 5 are also installed on the support frame 1, the three guide rods 5 are fixedly connected with the support frame 1, the threaded rod 4 is rotatably connected with the support frame 1, and the top end is connected with a motor. The threaded rod 4 and the three guide rods 5 penetrate the lifting platform 3. Therefore, when the motor drives the threaded rod 4 to rotate, the lifting platform 3 can move up and down.

[0033] A limiting block 6 is also fixedly connected inside the support frame 1, and the limiting block 6 is used for limiting the lifting platform 3. In addition, a fixing sleeve 10 is fixedly connected on the lifting platform 3, and an internal thread is formed in the inner side wall of the fixing sleeve 10.

[0034] In addition, a control shaft 8 is also provided, and the control shaft 8 comprises a threaded segment 81 and a connecting segment 82, and the threaded segment 81 and the connecting segment 82 are fixedly connected. The threaded segment 81 is provided with a thread, and is screw-connected with the fixing sleeve 10. The threaded segment 81 penetrates the fixing sleeve 10, and the top is fixedly connected with a lever 9, so as to facilitate the manual rotation of the control shaft 8.

[0035] And the connecting section 82 is provided with a mounting groove 11, and a spring 12 is sleeved outside the connecting section 82 and located at the position of the mounting groove 11, and a pressing device 13 is movably mounted. The pressing device 13 can move up and down in the mounting groove 11. When no external force is applied, the spring 12 makes the pressing device 13 at the lowermost position of the mounting groove 11. In addition, a stirring rod 14 is further arranged below the pressing device 13 and fixedly connected with the connecting section 82.

[0036] The pressing device 13 comprises a pressing plate 131 and a connecting sleeve 132. The connecting sleeve 132 is first mounted in the mounting groove 11 and can move up and down along the mounting groove 11, and the spring 12 can be protected inside the connecting sleeve 132. The pressing plate 131 is mounted outside the connecting sleeve 132. The diameter of the pressing plate 131 can be slightly smaller than the inner diameter of the barrel 7, so that the pressing plate 131 can extend into the barrel 7.

[0037] In addition, a cover plate 15 is further fixedly connected below the lifting platform 3, and when the lifting platform 3 moves downward to the position of the limiting block 6, the cover plate 15 is attached to the upper end surface of the barrel 7. The cover plate 15 can also press the barrel 7. In actual use, a pressure relief valve (which is prior art and not shown in the figure) can be arranged on the cover plate 15 to avoid excessive internal pressure caused by solvent evaporation during heating.

[0038] The implementation process and principle of the traditional Chinese medicine rhizoma polygonati component extraction device in the embodiment are as follows:

[0039] (1) The rhizoma polygonati is placed in the barrel 7, and then the barrel 7 is mounted in the extraction cylinder 2. If water is used as the solvent, water is added to the extraction cylinder 2 through the liquid inlet pipe 21 so that the water covers the rhizoma polygonati. (For example, the ratio of rhizoma polygonati powder to solvent is 1:5-1:10), and the rhizoma polygonati is soaked for a period of time (for example, 2-24 hours). Through the cooperation of the motor and the threaded rod 4, the lifting platform 3 is driven to move downward, the cover plate 15 is attached to the upper end surface of the barrel 7, and the barrel 7 is pressed.

[0040] (2) The solvent is heated by energizing the heating ring 24 to control the temperature and avoid large evaporation of the solvent. Heating can increase the speed of molecular thermal motion, increase the solubility and diffusion rate of effective components in the solvent, especially for polysaccharides and flavonoids in rhizoma polygonati, appropriate heating can make them more easily released from rhizoma polygonati cells into the extraction solvent, thereby improving the extraction efficiency.

[0041] In addition, after soaking for a period of time, the control shaft 8 can be manually rotated by the lever 9. Therefore, the control shaft 8 and the fixed sleeve 10 are screw-connected, so that when the control shaft 8 rotates, it also moves downward, and drives the pressing device 13 to move downward. When the pressing device 13 moves downward, the rhizoma polygonati is squeezed, so that the effective components in the rhizoma polygonati are squeezed out and enter the extraction solvent under the action of pressure, thereby promoting the release and dissolution of the effective components.

[0042] Because the presser 13 can move upward by the compression spring 12, the situation that the downward stroke of the presser 13 is too large, the pressure on the rhizoma polygonati and the barrel 7 is too large, and the barrel 7 is damaged can be avoided. The barrel 7 is protected.

[0043] When the control shaft 8 rotates, the stirring rod 14 also rotates and enters the rhizoma polygonati (powder) from below the presser 13. When rotating, the rhizoma polygonati and the solvent are stirred, the situation that the active ingredients in some areas are fully extracted while the active ingredients in other areas are not fully extracted is avoided, the extraction is more uniform, the extraction process is accelerated, and the time required for extraction can be reduced to a certain extent.

[0044] (Three): After the extraction is completed, the valve of the outlet pipe 22 is opened, the extracted liquid is first filtered by the filter screen 25 to remove the rhizoma polygonati particles and impurities, and then flows out. The subsequent step can be performed by collecting from below the outlet pipe 22.

[0045] The above-mentioned embodiments are only preferred embodiments of the utility model, and cannot be used to limit the range of protection of the utility model, and any non-substantial changes and replacements made by the person skilled in the art on the basis of the utility model belong to the range of protection required by the utility model.
