[0002] Notoginseng is a perennial erect herb, and its rhizome and fleshy parts are relatively precious traditional Chinese medicines, with the effects of hemostasis, promoting blood circulation to remove stasis, anti-inflammatory and analgesic, and nourishing. Its flowers and leaves also have the effect of clearing heat. Total notoginsenosides are the main active ingredients of notoginseng, including notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, ginsenoside Rb1, and ginsenoside Rd, which are mainly used for promoting blood circulation to remove stasis, dredging collaterals, inhibiting platelet aggregation, and increasing cerebral blood flow, and are commonly used in cerebrovascular sequelae, central retinal vein occlusion, and hyphema, etc.

[0003] In the process of extracting total notoginsenosides, first, notoginseng needs to be damaged and then extraction liquid is added. After mixing evenly, a separation and extraction device is used to filter out impurities and obtain the extraction liquid. Among them, the grinding and damage of notoginseng is an important step in saponin extraction. However, the existing device only performs simple single-stage filtration on notoginseng, with low grinding efficiency and unsatisfactory grinding effect, resulting in incomplete extraction of subsequent saponins, causing considerable waste and great economic losses. Therefore, it is objectively necessary to develop a high-efficiency separation device for extracting total notoginsenosides with high grinding efficiency, good grinding effect, and complete extraction.

The grinding chamber has a structure with a large upper port and a small lower port. An annular outer grinding is arranged on the inner wall of the grinding chamber, and a matching inner grinding is arranged inside the outer grinding. The annular gap between the outer grinding and the inner grinding gradually decreases from top to bottom. The mixing chamber has a structure with a small upper port and a large lower port, and the upper port of the mixing chamber is communicated with the lower port of the grinding chamber. A vertical cylinder is concentrically arranged inside the mixing chamber. Communication holes are processed on the upper part of the vertical cylinder, and the upper end of the vertical cylinder is fixed to the upper port of the mixing chamber. The bottom of the mixing chamber is communicated with the top of the separation chamber through a lower liquid pipe. A feed port and a cylinder are arranged at the top of the grinding chamber. The end of the piston rod of the cylinder is fixed with a motor. The output shaft of the motor extends into the grinding chamber and is connected with a rotating shaft. The lower end of the rotating shaft extends into the separation chamber. The inner grinding is fixed on the rotating shaft.

When in use, start the motor, and the motor drives the inner grinder, spiral blade, rubber ball and filter cylinder to rotate. The rubber ball is located in the lower liquid pipe and blocks it. Put Panax notoginseng into the grinding chamber from the feed port. The Panax notoginseng enters the annular gap between the outer grinder and the inner grinder, and is gradually ground fine under the friction between the inner grinder and the outer grinder.

Detailed Embodiments

[0015] The present utility model will be further described below with reference to the drawings, but the present utility model is not limited in any way. Any change or improvement based on the present utility model belongs to the protection scope of the present utility model.

[0016] As shown Figure 1 in the figure, the utility model comprises a grinding chamber 1, a mixing chamber 2 and a separation chamber 3. The grinding chamber 1 has a structure with a large upper port and a small lower port. An annular outer grinder 4 is arranged on the inner wall of the grinding chamber 1, and a matching inner grinder 5 is arranged inside the outer grinder 4. The annular gap between the outer grinder 4 and the inner grinder 5 gradually decreases from top to bottom. The mixing chamber 2 has a structure with a small upper port and a large lower port, and the upper port of the mixing chamber 2 is communicated with the lower port of the grinding chamber 1. A vertical cylinder 6 is concentrically arranged inside the mixing chamber 2. A communication hole is processed on the upper part of the vertical cylinder 6, and the upper end of the vertical cylinder 6 is fixed to the upper port of the mixing chamber 2. The bottom of the mixing chamber 2 is communicated with the top of the separation chamber 3 through a lower liquid pipe 7. A feed port and a cylinder 8 are arranged on the top of the grinding chamber 1. The end of the piston rod of the cylinder 8 is fixed with a motor 9. The output shaft of the motor 9 extends into the grinding chamber 1 and is connected with a rotating shaft 10. The lower end of the rotating shaft 10 extends into the separation chamber 3. The inner grinder 5 is fixed on the rotating shaft 10. A spiral blade 11 is arranged on the rotating shaft 10 inside the vertical cylinder 6. A rubber ball 12 is arranged on the rotating shaft 10 inside the lower liquid pipe 7. The rubber ball 12 has a certain elasticity. When it is stuffed into the lower liquid pipe 7, it can play a role in sealing and blocking the lower liquid pipe 7, preventing the extraction liquid in the mixing chamber 2 from falling into the separation chamber 3. Only when the extraction liquid and Panax notoginseng are fully mixed in the mixing chamber 2, can the rubber ball 12 be lifted upward. After the rubber ball 12 leaves the lower liquid pipe 7, the extraction liquid in the mixing chamber 2 can fall into the filter cylinder 13 in the separation chamber 3 through the lower liquid pipe 7. A filter cylinder 13 with an open upper end is arranged on the rotating shaft 10 in the separation chamber 3. A drain pipe is arranged at the bottom of the separation chamber 3. The cylinder 8 and the motor 9 are both existing devices, and their power and other parameters can be purchased and installed in the market according to actual needs

[0017] The utility model is used for the extraction of total saponins of Panax notoginseng. When in use, the motor 9 is started. The motor 9 drives the inner grinder 5, the spiral blade 11, the rubber ball 12 and the filter cylinder 13 to rotate. The rubber ball 12 is located in the lower liquid pipe 7 to block it. Panax notoginseng is put into the grinding chamber 1 from the feed port. The Panax notoginseng enters the annular gap between the outer grinder 4 and the inner grinder 5, and is subjected to friction, extrusion and kneading between the inner grinder 5 and the outer grinder 4, and is gradually ground fine. After the Panax notoginseng is ground fine, it falls into the vertical cylinder 6. At the same time, the extraction liquid is added into the mixing chamber 2. Under the action of the spiral blade 11, the extraction liquid and the Panax notoginseng powder in the vertical cylinder 6 are pushed to flow downward. After the mixed liquid touches the bottom of the mixing chamber 2, it flows reversely, enters the annular space between the vertical cylinder 6 and the outer wall of the mixing chamber 2 and flows upward, and then returns to the upper part of the vertical cylinder 6 again from the communication hole. And so on, the extraction liquid and the Panax notoginseng powder continuously circulate and flow in the mixing chamber 2, and the two are fully mixed. Then the cylinder 8 is started. The cylinder 8 drives the motor 9, the inner grinder 5, the spiral blade 11, the rubber ball 12 and the filter cylinder 13 to move upward, so that the rubber ball 12 moves upward and leaves from the upper end of the lower liquid pipe 7. The mixed liquid in the mixing chamber 2 falls from the lower liquid pipe 7 into the filter cylinder 13. And the filter cylinder 13 is in a rotating state, so that impurities can be blocked in the filter cylinder 13, and the extraction liquid falls into the separation chamber 3 and then is discharged from the drain pipe. In the utility model, the fixed outer grinder 4 and the rotating inner grinder 5 are used to grind Panax notoginseng, and the annular gap between the outer grinder 4 and the inner grinder 5 gradually decreases from top to bottom, so that the Panax notoginseng can be gradually ground into fine powder, the grinding efficiency is high, and the grinding effect is good. Secondly, after the Panax notoginseng powder enters the mixing chamber 2, the structure of the vertical cylinder 6 and the spiral blade 11 is adopted, so that the extraction liquid and the Panax notoginseng powder can continuously circulate and flow in the mixing chamber 2, which can ensure that the two can be fully mixed, and further realize the full extraction of notoginsenoside and avoid the waste of notoginsenoside. Finally, the extraction liquid enters the rotating filter cylinder 13, and impurities such as Panax notoginseng residues in the extraction liquid can be efficiently separated, and the extraction liquid can be quickly thrown out. Finally, the relatively pure extraction liquid is discharged from the drain pipe, and the separation effect is good.

[0018] A material guiding cone 14 with a large upper port and a small lower port is sleeved on the rotating shaft 10 above the inner grinder 5. There is a blanking gap between the lower port of the material guiding cone 14 and the rotating shaft 10. The upper port of the material guiding cone 14 is fixed at the top of the grinding chamber 1. The feed port is located at the top of the grinding chamber 1 above the material guiding cone 14. A material distributing cone with an upward vertex angle is arranged at the top of the inner grinder 5. When Panax notoginseng is put into the grinding chamber 1 from the feed port and enters the annular gap between the inner grinder 5 and the outer grinder 4, there is a problem of uneven blanking, resulting in uneven distribution of Panax notoginseng in the circumferential direction of the annular gap, which affects the grinding effect of Panax notoginseng. In order to solve this problem, the material guiding cone 14 is set. Panax notoginseng enters the material guiding cone 14 from the feed port, and then falls from the lower end of the material guiding cone 14 to the top of the center position of the material distributing cone and evenly falls around, playing a role of material equalization and ensuring the grinding effect of Panax notoginseng as much as possible.

[0019] Stirring rods 15 are provided on the rotating shaft 10 inside the material guiding cone 14 and the rotating shaft 10 inside the vertical cylinder 6. The material guiding cone 14 is used to guide the notoginseng powder to the top of the material distributing cone, so that the notoginseng powder can slide evenly from the middle to the surroundings. However, in the actual use process, it is found that the notoginseng will be blocked inside the material guiding cone 14. In order to solve this problem, the stirring rod 15 is provided to stir the notoginseng, promote the smooth falling of the notoginseng, and prevent blockage.

[0020] Strip-shaped material lifting plates 16 are provided on the rotating shaft 10 inside the mixing chamber 2. The side surface of the material lifting plate 16 is an inclined surface, and the lower end surface of the material lifting plate 16 contacts the bottom of the mixing chamber 2. In the actual use process, it is found that a small part of the notoginseng powder will be deposited at the bottom of the mixing chamber 2 and cannot be well mixed with the extraction liquid. In order to solve this problem, the material lifting plate 16 is provided. During operation, the material lifting plate 16 rotates together with the rotating shaft 10. During the rotation process, the deposited notoginseng powder is lifted, so that the notoginseng powder moves along the side surface of the material lifting plate 16 and is finally thrown out obliquely upward, so that it is mixed into the extraction liquid. At the same time, the extraction liquid at the bottom of the mixing chamber 2 is stirred to prevent the notoginseng powder from falling and depositing, and improve the mixing efficiency of the notoginseng powder and the extraction liquid.

[0021] Ultrasonic vibration rods 17 are provided on the side wall of the mixing chamber 2. The ultrasonic vibration rods 17 are of the prior art and can generate vibrations. In this device, the mixture of notoginseng powder and extraction liquid is vibrated by the ultrasonic vibration rods 17 to play a stirring role, which can promote the mixing of the notoginseng powder and the extraction liquid and improve the mixing efficiency and mixing effect of the two.

[0022] A cylindrical filter screen 18 is concentrically arranged in the separation chamber 3 outside the filter cylinder 13. The pore size of the cylindrical filter screen 18 is smaller than the pore size of the filter cylinder 13. The filter cylinder 13 performs primary filtration on the extraction liquid, and then the cylindrical filter screen 18 is used to perform secondary filtration on the extraction liquid, which can further separate the finer particulate impurities in the extraction liquid and improve the purity of the extraction liquid. In addition, the filter cylinder 13 and the cylindrical filter screen 18 cooperate with each other. When one of them is damaged, the other can still separate the extraction liquid to ensure the separation effect of the extraction liquid.

[0023] An anti-overflow ring 19 is provided at the upper port of the filter cylinder 13. Considering that in the use process of this device, the filter cylinder 13 rotates together with the rotating shaft 10. During the use process, if the extraction liquid falling into the filter cylinder 13 is not filtered in time, part of it will remain in the filter cylinder 13. Under the action of centrifugal force, it may move upward along the side wall of the filter cylinder 13 and finally be thrown out from the upper end of the filter cylinder 13, thereby reducing the separation effect of the extraction liquid and affecting the quality of the notoginseng extraction liquid. In order to avoid the occurrence of the above situation, the anti-overflow ring 19 is provided. When the excess extraction liquid in the filter cylinder 13 flows upward, it is blocked by the anti-overflow ring 19 and returns to the filter cylinder 13, and will not flow out directly, ensuring the extraction quality of the extraction liquid.
