Description

Technical Field

[0001] The utility model relates to the technical field of macroporous resin enrichment, in particular to a macroporous resin enrichment device for extracting Panax notoginseng. Background Art

[0002] Panax notoginseng is a plant of the genus Panax, Araliaceae. It is warm in nature, sweet in taste, slightly bitter, and enters the stomach meridian. It has the effects of promoting blood circulation and dispersing blood stasis, reducing swelling and relieving pain, and stopping bleeding and removing blood stasis. The natural chemical composition of Panax notoginseng includes saponins, flavonoids, sterols, volatile oils, amino acids, polysaccharides, etc., and the composition is relatively complex. Among them, different growth parts of Panax notoginseng contain more than 20 saponin components, and its main active ingredient is Panax notoginseng total saponins, which are used to prevent and treat cardiovascular and cerebrovascular diseases such as hyperlipidemia, hypertension, atherosclerosis, myocardial ischemia, and ischemic stroke. Panax notoginseng total saponins are mainly extracted from Panax notoginseng medicinal materials. The extraction method mainly includes the following processing steps: drying Panax notoginseng, crushing, ethanol extraction, vacuum recovery of ethanol, macroporous resin adsorption, ethanol elution, vacuum recovery of ethanol, decolorization, concentration, drying, etc.

[0003] The principle of using a macroporous resin enrichment device to extract the active ingredients of Panax notoginseng is to selectively adsorb organic matter from the solution through physical adsorption, thereby achieving the purpose of separation and purification. However, current macroporous resin enrichment devices still have the following problems during use: First, the macroporous resin has poor fluidity and a relatively slow contact speed with the original solution, resulting in low adsorption efficiency; second, the extraction of active ingredients only undergoes a single extraction and adsorption process, which easily leads to incomplete extraction of the active ingredients in the original solution, resulting in waste of active ingredients and affecting the extraction effect of the macroporous resin. Therefore, it is an objective need to develop a macroporous resin enrichment device for Panax notoginseng extraction with good macroporous resin fluidity, high enrichment efficiency, and good extraction effect.

DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements based on the present invention fall within the scope of protection of the present invention.

[0016] like Figures 1-2 As shown, the utility model includes a box body 1 and a liquid inlet arranged on the top of the box body 1. The Panax notoginseng raw liquid is introduced into the liquid inlet chamber 4 of the box body 1 from the liquid inlet. The interior of the box body 1 is divided into a liquid inlet chamber 4, an extraction chamber 5 and a liquid outlet chamber 6 from top to bottom by an upper partition 2 and a lower partition 3. The Panax notoginseng raw liquid completes the extraction of effective components in the extraction chamber 5, and the remaining material liquid after extraction flows into the liquid outlet chamber 6. A central axis 7 is provided on the vertical center line of the extraction chamber 5, and an internal gear 8 is provided on the central axis 7. The upper end of the central axis 7 extends out of the top of the box body 1 and is connected to a driving mechanism. The driving mechanism is a prior art and is used to drive the central axis 7 and the central gear 11 to rotate. A circle of vertical pipes 9 and a circle of vertical shafts 10 are arranged around the central axis 7 in sequence. The vertical pipe 9 and the upper partition 2 are sealed and rotated in a connected structure, and the vertical shaft 10 and the upper partition 2 are connected in a connected structure. The connection structure ensures that the vertical pipe 9 and the vertical shaft 10 can rotate freely. The upper end of the vertical pipe 9 is connected with the liquid inlet chamber 4, and the Panax notoginseng raw liquid in the liquid inlet chamber 4 is discharged into the inner ring extraction cylinder 13 through the vertical pipe 9. A middle gear 11 is provided on the vertical pipe 9, and an outer gear 12 is provided on the vertical shaft 10. The inner side of the middle gear 11 is meshed with the inner gear 8, and the outer side is meshed with the corresponding outer gear 12. The lower ends of the vertical pipe 9 and the vertical shaft 10 are respectively connected with the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14. The upper end height of the inner ring extraction cylinder 13 is higher than the upper end height of the outer ring extraction cylinder 14. The inner ring extraction cylinder 13 and the outer ring extraction cylinder 14 are both filled with macroporous resin 15. The lower ends of the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14 are provided with a filter 16. The lower end of the outer ring extraction cylinder 14 is connected with the liquid outlet chamber 6, and the liquid outlet chamber 6 is provided with a liquid outlet pipe 17. In this device, the number of internal gears 8 is one, and the number of middle gears 11 is determined according to actual conditions such as the diameter of the internal gear 8. The middle gears 11 are usually evenly distributed around the circumference. The number of external gears 12 is the same as that of the middle gears 11 and is also evenly distributed around the circumference. The internal gear 8 drives the middle gear 11 to rotate, and the middle gear 11 drives the outer gear 12 to rotate.

[0017] When the utility model is in operation, the driving mechanism is started, the driving mechanism drives the middle shaft 7 to rotate, the middle shaft 7 drives the inner gear 8 to rotate, the inner gear 8 drives the middle gear 11 to rotate, the middle gear 11 drives the vertical pipe 9 and the outer gear 12 to rotate, the outer gear 12 drives the vertical shaft 10 to rotate, the vertical pipe 9 drives the inner ring extraction cylinder 13 to rotate, the vertical shaft 10 drives the outer ring extraction cylinder 14 to rotate, and when the extraction cylinder rotates, it drives the macroporous resin 15 inside it to rotate, and the Panax notoginseng raw liquid is introduced into the liquid inlet 4, and then is divided along each vertical pipe 9 and enters the inner ring extraction cylinder 13 As the Panax notoginseng stock solution continues to flow downward, it contacts the macroporous resin 15 in the inner ring extraction cylinder 13. The macroporous resin 15 separates, extracts and continuously enriches the effective components in the Panax notoginseng stock solution. Then it flows into the extraction chamber 5 from the bottom of the inner ring extraction cylinder 13, and then enters it from the upper end of the outer ring extraction cylinder 14. As it flows downward, it contacts the macroporous resin 15 in the outer ring extraction cylinder 14, and again separates, extracts and continuously enriches the effective components in the Panax notoginseng stock solution. Finally, the remaining stock solution flows into the liquid outlet chamber 6 and is discharged from the liquid outlet pipe 17.

[0018] In the present invention, the macroporous resin 15 is respectively installed in the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14, and the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14 are in a rotating process, and the macroporous resin 15 rotates accordingly. When the Panax notoginseng stock solution is injected therein, the macroporous resin 15 is in a relatively stable suspended state and has good fluidity. During the downward flow of the stock solution, it can contact with the macroporous resin 15 more easily and quickly, making full use of all the surface area of the macroporous resin 15. The contact speed between the Panax notoginseng stock solution and the macroporous resin 15 is relatively fast, and the adsorption and enrichment efficiency of the Panax notoginseng stock solution by the macroporous resin 15 is relatively high; secondly, when the Panax notoginseng stock solution is adsorbed, it first flows into the inner ring extraction cylinder 13 for the first adsorption, and then flows into the outer ring extraction cylinder 14 for the second adsorption. After the two extraction and adsorption, the effective components of the Panax notoginseng stock solution can be extracted more completely, reducing or even eliminating the waste of effective components, and improving the extraction effect of the macroporous resin 15.

[0019] A stirring blade 18 is provided on the central shaft 7 below the internal gear 8. The stirring blade 18 is provided on the central shaft 7 and rotates synchronously with the central shaft 7. During the rotation, the Panax notoginseng stock solution in the extraction chamber 5 is stirred, so that the Panax notoginseng stock solution spirally flows in the extraction chamber 5, averaging the concentration of the effective ingredients of the Panax notoginseng stock solution in the extraction chamber 5, thereby improving the extraction efficiency and extraction effect of the Panax notoginseng stock solution in the outer ring extraction cylinder 14.

[0020] A drain pipe 19 connecting the extraction chamber 5 and the liquid outlet chamber 6 is provided on the lower partition 3, and a drain valve is provided on the drain pipe 19. A macroporous resin layer 20 is provided in the liquid outlet chamber 6, and the liquid outlet pipe 6 is located at the bottom of the liquid outlet chamber 6. During normal operation of the device, the macroporous resin layer 20 is used to extract the Panax notoginseng stock solution again, further improving the extraction effect of the effective components in the Panax notoginseng stock solution. After completing the extraction of the Panax notoginseng stock solution, due to the structural reasons of the device, it will be found that there is still Panax notoginseng stock solution retained in the extraction chamber 5. If it is not extracted, it will cause waste of the Panax notoginseng stock solution. Therefore, a drain pipe 19 and a large bag drain valve are provided. The Panax notoginseng stock solution retained in the extraction chamber 5 flows from the drain pipe 19 into the liquid outlet chamber 6, and is extracted and filtered again by the macroporous resin layer 20 and then discharged, avoiding waste of effective components in the Panax notoginseng stock solution.

[0021] In order to facilitate the installation of components such as the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14, the vertical axis 10 between the outer gear 12 and the outer ring extraction cylinder 14 and the vertical pipe 9 between the middle gear 11 and the inner ring extraction cylinder 13 are both segmented structures, and the two segments are connected by flanges 21. During actual use, when the macroporous resin 15 needs to be washed and regenerated, the flanges can be loosened and the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14 can be removed.

[0022] A reflux pipe 22 is provided on the liquid outlet pipe 17, and the end of the reflux pipe 22 is connected to the liquid inlet chamber 4. During the extraction process of the effective components of the Panax notoginseng raw liquid, the raw liquid discharged from the liquid outlet pipe 17 can be tested. When the test result shows that the raw liquid still contains a certain amount of effective components, the raw liquid can be returned to the liquid inlet chamber 4 through the reflux pipe 22, and the effective components can be extracted again, thereby further reducing the content of the effective components in the raw liquid and reducing the waste of effective components.

[0023] A rubber layer 23 is provided on the inner wall of the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14. Since the macroporous resin 15 is relatively fragile, it is easy to collide with the inner wall of the extraction cylinder when the inner ring extraction cylinder 13 and the outer ring extraction cylinder 14 rotate, thereby causing the problem of fragmentation. In order to prevent the macroporous resin 15 from fragmenting, a rubber layer 23 is provided. The rubber layer 23 has good flexibility and elasticity, which can cushion the macroporous resin, reduce the impact force, and thus maintain the integrity of the macroporous resin and increase the service life of the macroporous resin.

[0024] After the Panax notoginseng stock solution is extracted and enriched by the macroporous resin 15, the remaining liquid flows into the liquid outlet cavity 6 for further extraction of the effective components. In order to prevent the macroporous resin particles in the macroporous resin layer 20 from being discharged from the liquid outlet pipe 17, a filtering structure can be provided at the inlet end of the liquid outlet pipe 17.
