Description

Technical Field

[0001] The invention relates to the technical field of drug preparation, in particular to a peony bark extraction device for preparing Jindan Fuyan granules. Background Art

[0002] Jindan Fuyan Granules is a Chinese patent medicine, mainly used to treat chronic pelvic inflammatory disease and other diseases that are diagnosed as internal dampness and heat in traditional Chinese medicine. The main ingredients of Jindan Fuyan Granules include thirteen kinds of Chinese medicinal materials, including peony bark, honeysuckle, red peony root, curcuma, Corydalis yanhusuo (vinegar-processed), Patrinia scabra, Sargentodoxa chinensis, peach kernel, angelica sinensis, myrrh (processed), cinnamon twig, Cyperus rotundus, and Coix seed.

[0003] The traditional Chinese medicine preparation process of Jindan Fuyan Granule is a complex and delicate process, which involves the steps of extraction, mixing and granulation of various Chinese medicinal materials. Thirteen kinds of Chinese medicinal materials, including high-quality peony bark, honeysuckle, red peony root, curcuma, corydalis (vinegar), Patrinia, Sargentodoxae, peach kernel, angelica, myrrh (processed), cinnamon twig, cyperus, and coix seed, are selected as raw materials in the extraction operation. These medicinal materials must meet the relevant medicinal material standards to ensure efficacy and safety. The existing peony bark extraction device usually uses various extraction technologies to extract the effective components in peony bark, such as solvent extraction, ultrasonic extraction, supercritical CO2 extraction, etc., to extract the effective components in peony bark, but the above extraction efficiency is low and not suitable for production needs. Therefore, a continuous extraction device is also proposed for the above extraction method. It can be understood that the peony bark raw material and extraction or extraction agent are added to the extraction device in a timely and quantitative manner through the equipment to achieve continuous extraction and improve the extraction efficiency.

[0004] In order to ensure the efficient extraction of effective ingredients in the peony bark, the existing continuous extraction device of the peony bark will mostly drive the contact efficiency between the peony bark and the extraction solvent by accelerating the rotation speed of the stirring paddle, thereby improving the extraction efficiency and extraction quality. However, during the rapid stirring process, there are also problems such as the peony bark breaking and producing fragments of different sizes distributed in the extraction barrel, which is not convenient for the operator to clean uniformly, especially when new peony bark is continuously added. This effect will be more obvious, increasing the difficulty of cleaning the subsequent extraction barrel. At the same time, the successively increased peony bark residue particles cannot be processed, which will seriously affect the cleanliness of the subsequent extract. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a peony bark extraction device for preparing Jindan Fuyan granules, aiming to solve the problem that the cleaning of medicinal residues in the existing peony bark extraction device is difficult, which seriously affects the cleanliness of the subsequent extract.

[0006] The present invention provides a peony bark extraction device for preparing Jindan Fuyan granules, comprising an extraction assembly for spirally stirring a mixed solution, a slag removal assembly disposed at the bottom of the extraction assembly and connected thereto, a solenoid valve at least partially embedded at one side of the bottom of the extraction assembly, and a slag collection assembly disposed in the extraction assembly and close to the slag removal assembly, wherein the slag collection assembly is connected to the slag removal assembly; The slag collection assembly includes an outer partition fixedly arranged at the bottom end of the extraction assembly, a filter cylinder movably arranged inside the outer partition, and an inner partition arranged inside the filter cylinder and fixedly connected to the outer partition, the outer partition surface is provided with an outer through groove for connecting to the internal space of the extraction assembly, and the inner partition is provided with an inner through groove for connecting to the internal space of the extraction assembly, so that the medicine in the extraction assembly can enter the outer partition, the filter cylinder and the inner side of the inner partition in sequence; The filter cylinder includes a one-way shaft disc embedded in the outer separator, a connecting pipe embedded in the center of the one-way shaft disc and used to connect with the slag removal assembly, at least three cylinder walls extending outward from the edge of the one-way shaft disc away from the connecting pipe, an outer filter screen extending along the cylinder wall toward the outer separator, and an inner filter screen extending along the cylinder wall away from the outer filter screen toward the inner separator; The medicine between the outer spacer and the filter cylinder can be filtered through the outer filter screen, and the medicine between the filter cylinder and the inner spacer can be filtered through the inner filter screen.

[0007] As described above, the spiral stirring of the extraction assembly drives the mixed solution of the peony bark raw material and the ethanol solution to generate a vortex, so that the peony bark raw material and the ethanol solution are fully stirred and contacted to improve the extraction quality. At the same time, the eddy current characteristics can also be used to guide the peony bark residue in the mixed solution to converge toward the residue collection assembly at the center, and the residue will first adhere to the surface of the outer partition tube and rotate, and enter the outer partition tube when it reaches the outer through groove, and the residue will be initially filtered through the filter barrel, which is implemented by an outer filter screen arranged between the outer partition tube and the cylinder wall. When a certain amount of residue is accumulated on the surface of the outer filter screen, the surface resistance of the outer filter screen increases. After that, the residue is isolated by the outer filter screen and will enter the filter cylinder along the gap of the cylinder wall, and will be filtered twice through the inner filter screen and drive the residue to enter the inner through groove into the inner partition tube to collect the residue uniformly, and then the residue is filtered and collected in an internal circulation through the residue removal assembly connected to the inner partition tube, retaining the solution to filter the residue, thereby improving the cleaning efficiency and saving the cleaning time, and solving the problem that the residue cleaning in the existing peony bark extraction device is difficult and seriously affects the cleanliness of the subsequent extract.

[0008] Furthermore, a slide groove for accommodating the one-way shaft disc is embedded on the outer spacer and located between the inner spacers.

[0009] Furthermore, the extraction assembly includes an extraction barrel for accommodating the slag collection assembly, a stirring assembly arranged on a side of the extraction barrel away from the slag removal assembly, and a discharge port is provided on the top of the extraction barrel.

[0010] Furthermore, the stirring assembly includes a motor, an output gear arranged at the output end of the motor, a transmission gear circumferentially connected to the output gear, a transmission shaft arranged axially of the transmission gear, and multiple groups of stirring paddles arranged circumferentially of the transmission shaft.

[0011] Furthermore, the stirring paddle is at least partially embedded in the inner side of the inner partition, and the stirring paddle is used to axially output the reagents in the extraction barrel to converge toward the stirring paddle and to be sequentially introduced into the slag collection assembly for filtration.

[0012] Furthermore, the slag removal assembly includes a base, a sewage collection and circulation component embedded in the base and connected to the connecting pipe, and a shock absorbing seat at least partially embedded in the base on a side away from the extraction assembly.

[0013] Furthermore, the sewage collection and circulation assembly includes a circulation pump arranged at the bottom of the connecting pipe, a circulation pipe arranged on the side of the circulation pump away from the connecting pipe, and a sewage collection pan embedded in the circulation pipe along the base on the side close to the circulation pump.

[0014] Furthermore, a shaft tooth inclined in the axial direction is provided on one side of the one-way shaft disc close to the slide groove, and a spring buckle abutting against the shaft tooth extends from the slide groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Furthermore, a slide groove 46 for accommodating a one-way shaft disk 421 is embedded on the outer partition 41 and between the inner partitions 43. The extraction assembly 1 includes an extraction barrel 11 for accommodating the slag collection assembly 4, a stirring component arranged on the side of the extraction barrel 11 away from the slag removal assembly 2, and a discharge port 17 is opened on the top of the extraction barrel 11.

[0023] It should be noted that, for the selection before extraction of peony bark, high-quality peony root bark is usually used as the raw material, and is obtained after pretreatment such as washing and removing impurities, and the solvent extraction method is adopted in this application, and the solution used for peony bark extraction may vary depending on the target extract. Generally speaking, the various active ingredients in peony bark, such as paeoniflorin, paeonol and flavonoids, can be extracted by different solvents, including: Ethanol solution: Ethanol is one of the commonly used solvents for extracting various components in peony bark. Studies have shown that using a 60% volume fraction ethanol solution for homogenate extraction can better extract active ingredients such as paeoniflorin and paeonol in peony bark. The advantage of ethanol solution is that its extraction effect is stable and easy to subsequently process.

[0024] Methanol solution: Methanol is also used for the extraction of Paeonia suffruticosa in some cases. For example, in the experiment of identifying Paeonia suffruticosa extract, methanol may be used as a solvent to prepare the test solution. However, it should be noted that methanol has a certain toxicity, so safety regulations should be strictly followed during the operation.

[0025] Alkaline solution: For the flavonoids in Paeonia suffruticosa, since most of them have phenol-OH in their molecular structure and are weakly acidic, alkaline solutions can be used for extraction. Commonly used alkaline solutions include sodium carbonate, sodium hydroxide, calcium hydroxide, etc. However, when using alkaline solutions for extraction, it is necessary to pay attention to controlling the concentration of the solution and the extraction conditions to avoid damaging the molecular structure of the flavonoids.

[0026] Hot water: In some cases, hot water can also be used as an extraction solvent. The advantages of hot water extraction are simple operation, low cost, and better extraction effect for certain components with good thermal stability. However, it should be noted that hot water extraction may cause the loss of some heat-sensitive components.

[0027] Therefore, in order to ensure the stability of the effect of the subsequent Paeonia suffruticosa extract product, ethanol solution can be used as the key extraction solution in the solvent extraction.

[0028] In the specific implementation, the operator can first introduce the pretreated peony bark raw material and the ethanol solution of a specific ratio into the extraction barrel 11 along the feed port 17 according to the extraction purity requirements, and control the stirring component on the extraction assembly 1 through the controller to stir the peony bark raw material and the ethanol solution, so that the peony bark raw material is fully in contact with the ethanol solution to improve the extraction quality. In some optional embodiments, the controller can be set at any convenient position for the operator to operate on the peony bark extraction device for preparing Jindan Fuyan granules, and the controller can be an MCU (Microcontroller Unit; microcontroller unit) chip, so as to realize the overall control of the peony bark extraction device for preparing Jindan Fuyan granules through the MCU chip, wherein the controller is electrically connected to the peony bark extraction device for preparing Jindan Fuyan granules, and the electrical connection includes a wired connection and a wireless connection, and the wireless connection method includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, zigbee, and the wired connection method includes but is not limited to a USB line connecting the peony bark extraction device for preparing Jindan Fuyan granules to the controller, and then the controller controls the motor 12 to start, and drives the output gear 13 at its output end to rotate, and then the output gear 13 drives the transmission gear 14, the transmission shaft 15 and the stirring paddle 16 to rotate axially in turn, so as to realize the stirring and mixing of the peony bark raw material and the ethanol solution in the extraction barrel 11, and the stirring time and driving frequency of the stirring paddle 16 are specific, first, the motor 12 can be driven in the reverse direction of the one-way shaft disk 421 for 5 to 10 minutes, such as Figure 6 In the opposite direction of the arrow shown, the filter cartridge 42 will not rotate with the unidirectional rotation trajectory design during this process, and this process belongs to the preliminary extraction process, so that the peony bark raw material is fully soaked with the ethanol solution. After that, the motor 12 is turned on according to the driving frequency of 6 to 10 times per minute, and the driving time of each time is 3 to 5 seconds. In addition, in some optional embodiments, in order to improve the stirring efficiency of the stirring paddle 16, the motor 12 can adopt a servo motor with a bidirectional output, so that the motor 12 is driven by a left-right interval driving method. It can be understood that it turns left first and then right. In this process, The raw material and solution in the extraction barrel 11 tumble, achieving full contact between the peony bark raw material and the ethanol solution, thereby improving the quality of subsequent extraction. During the stirring process, the stirring paddle 16 can also drive the peony bark raw material and the ethanol solution in the extraction barrel 11 to follow its rotation direction to form a vortex. After the extraction is sufficient under the action of the vortex, the remaining medicinal residues will be uniformly gathered toward the residue collection assembly 4 at the center of the vortex. It should be noted that the residue collection assembly 4 is connected to the internal space of the extraction barrel 11. Therefore, the stirring paddle 16 partially located in the residue collection assembly 4 can cause the solution in the extraction barrel 11 to generate a vortex during the rotation process. When the vortex moves along Figure 6When rotating in the direction of the arrow shown, the drug residue will first adhere to the surface of the outer partition 41 and rotate, and enter the outer partition 41 when reaching the outer through groove 44, and the drug residue will be initially filtered through the filter cylinder 42, which is implemented by the outer filter screen 424 arranged between the outer partition 41 and the cylinder wall 423. When a certain amount of drug residue is accumulated on the surface of the outer filter screen 424, the surface resistance of the outer filter screen 424 increases, and it follows the direction of the vortex as shown in FIG. Figure 3 The medicine residue is rotated in the direction of the arrow, and then the medicine residue is isolated by the outer filter screen 424 and enters the filter cylinder 42 along the gap of the cylinder wall 423, and is filtered twice by the inner filter screen 425 and drives the medicine residue to enter the inner partition cylinder 43 toward the inner groove 45 for unified collection of the medicine residue. Figure 3 When the filter cartridge 42 rotates in the reverse direction as indicated by the middle arrow, the one-way shaft disk 421 abuts against the spring catch in the slide groove 46 and does not rotate with it. It can be understood that the medicine residue will enter the residue collecting assembly 4 in one direction, preventing the medicine residue originally collected under the reverse vortex from escaping from the residue collecting assembly 4.

[0029] Furthermore, when a large amount of peony bark raw materials are uniformly gathered at the inner partition tube 43, the extraction agent circulating at a high speed in the extraction barrel 11 will also impact the drug residue collected in the inner partition tube 43, and ensure that the drug residue is located in the inner partition tube 43 and does not disperse while fully extracting the peony bark raw materials. After that, when the peony bark raw materials reach the specified extraction time, the operator can control the circulation pump 22 to start, and the circulation pump 22 located directly below the inner partition tube 43 will circulate and extract the solution with a large amount of drug residue accumulated. The extracted solution will be uniformly filtered through the sewage collecting tray 23 directly below the circulation pump 22, and the filtered solution will be filtered again through the circulation pipe 24. The extract is introduced into the extraction barrel 11, and then the operator only needs to take out the collecting plate 23 along the base 21 at regular intervals for cleaning or replacement. The operation is simple and quick and convenient for the unified collection of the medicinal residues. Afterwards, the circulating pump 22 is turned on for a certain period of time and then turned off, and the solenoid valve 3 is opened to guide the extraction solution in the extraction barrel 11 for use to ensure the cleanliness of the solution. In some optional embodiments, a filter net can be further provided at the discharge port of the solenoid valve 3 to further improve the cleanliness of the guided solution. In the process of guiding the solution, the operator can also continue to add the peony bark raw material and the new ethanol solution in sequence along the discharge port 17 to achieve continuous extraction and improve the extraction efficiency.

[0030] In addition, in some optional embodiments of the present invention, Figure 7As shown, the slag collecting assembly 4 can also be free of the filter cylinder 42 and directly fix the outer partition cylinder 41 and the inner partition cylinder 43 on the inner bottom of the extraction barrel 11, and open two relative outer through grooves 44 and inner through grooves 45 on the outer partition cylinder 41 and the inner partition cylinder 43 respectively. The purpose of this operation is to reduce the solution resistance in the slag collecting assembly 4 so that the medicinal residue can follow the eddy current direction and efficiently enter the slag collecting assembly 4. At the same time, the circulating pump 22 is in a normally open state, and the solution in the slag collecting assembly 4 can be continuously circulated and filtered. Due to the increase in the filtration amount, the volume or thickness of the corresponding dirt collecting tray 23 needs to be increased accordingly, and in order to ensure the filtration effect and realize continuous extraction, the replacement frequency of the dirt collecting tray 23 also needs to be increased accordingly relative to the above-mentioned embodiment.

[0031] In summary, the spiral stirring of the extraction assembly 1 drives the mixed solution of the peony bark raw material and the ethanol solution to generate a vortex, so that the peony bark raw material and the ethanol solution are fully stirred and contacted to improve the extraction quality. At the same time, the eddy current characteristics can also be used to guide the peony bark residue in the mixed solution to converge toward the residue collection assembly 4 at the center, and the residue will first adhere to the surface of the outer partition 41 and rotate, and enter the outer partition 41 when reaching the outer groove 44, and the residue will be preliminarily filtered through the filter cylinder 42, which is implemented by the outer filter screen 424 arranged between the outer partition 41 and the cylinder wall 423. When the outer filter screen 424 is After a certain amount of medicinal residue is accumulated on the surface, the surface resistance of the outer filter screen 424 increases. After that, the medicinal residue is isolated by the outer filter screen 424 and enters the filter cylinder 42 along the gap of the cylinder wall 423, and is filtered twice through the inner filter screen 425 and drives the medicinal residue to enter the inner through groove 45 into the inner partition cylinder 43 for unified collection of the medicinal residue. Then, the internal circulation filtration and collection are carried out through the residue removal assembly 2 connected to the inner partition cylinder 43, and the solution is retained to filter the medicinal residue, thereby improving the cleaning efficiency and saving the cleaning time, and solving the problem that the medicinal residue cleaning in the existing peony bark extraction device is difficult and seriously affects the cleanliness of the subsequent extraction liquid.
