Description

Technical Field

[0001] The invention belongs to the technical field of drug liquid extraction, in particular to an extraction system and extraction equipment for drug liquid for treating skin wounds. Background Art

[0002] When extracting medicinal solutions for treating skin wounds, it is usually necessary to crush plant tissues or Chinese herbal medicines containing therapeutic effects and mix them with the corresponding solution. During the extraction process of the medicinal solution, insufficient pretreatment of the raw materials leads to incomplete extraction of the active ingredients, affecting the efficacy of the medicinal solution. In addition, existing equipment often has difficulty in flexibly adjusting process parameters when processing different types of plant raw materials.

The grinding ring is inserted into the annular net. The above scheme adopts two concentric grinding wheels, and the grinding wheels have grinding plates. The two grinding wheels rotate in opposite directions, so that the traditional Chinese medicine continuously collides between the grinding wheels, and the second grinding wheel and the grinding ring are also ground, making the grinding rate faster and more efficient.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] The present invention discloses an extraction system for treating skin wounds, comprising a pretreatment module, a multi-stage solvent extraction module, a separation and purification module, a liquid preparation module and an intelligent control system;

[0041] The pretreatment module is used to clean and crush the raw materials. Through precise crushing and drying, the plant raw materials can be pretreated to the optimal state suitable for extraction, increasing the contact area between the raw materials and the solvent, improving the subsequent extraction efficiency, and ensuring the consistency and stability of the raw materials, laying a good foundation for the extraction process.

[0042] The multi-stage solvent extraction module is used to bring the solvent into contact with the pretreated plant material under sufficient stirring in the extraction component 4, so that the active ingredients are continuously dissolved in the solvent. At the same time, during the extraction process, according to the preset extraction process, solvents of different polarities enter each extraction tank through the solvent inlet in turn, and come into contact with the pretreated plant material under sufficient stirring by the stirring device, so that the active ingredients are continuously dissolved in the solvent. The temperature, pressure, stirring speed, solvent flow rate and other parameters of each extraction tank are precisely controlled by the intelligent control system to realize the automation and precision operation of multi-stage solvent extraction. The multi-stage extraction method can carry out targeted extraction of active ingredients of different polarities and different solubilities, maximize the extraction rate of active ingredients, and avoid the problem of incomplete extraction caused by traditional single solvent extraction;

[0043] The separation and purification module combines membrane separation with chromatographic separation to achieve efficient separation and purification of the extract, preliminarily realizing solid-liquid separation and removal of macromolecular impurities. The separation and purification process is carried out in a closed system, effectively preventing external contamination and ensuring the sterility of the drug solution.

[0044] The drug solution preparation module is used to achieve precise drug solution preparation, ensure the consistency of quality and composition of each batch of drug solution, and meet the personalized treatment needs in different clinical application scenarios. During the drug solution preparation stage, the formula parameters of the drug solution are pre-set through the intelligent control system according to the type, severity and treatment needs of the skin trauma, including the concentration of different active ingredients, the type and amount of solvents, the proportion of additives, etc. After the extract is separated and purified, it is transported through the drug solution according to the set formula ratio, and is evenly mixed with the solvent and additives under sufficient stirring of the stirring device to form the final drug solution for treating skin trauma. The drug solution preparation module can achieve precise drug solution preparation, ensure the consistency of quality and composition of each batch of drug solution, and meet the personalized treatment needs in different clinical application scenarios;

[0045] The intelligent control system is used for fully automated and intelligent operation of the equipment, improving production efficiency and product quality stability. The intelligent control system realizes the fully automated and intelligent operation of the extraction equipment, greatly improving production efficiency and product quality stability. By pre-writing a comprehensive control program, it can accurately control every link in the extraction process, ensuring the accurate execution of the extraction process and avoiding the impact of human operational errors on the extraction effect. At the same time, the system has automatic fault diagnosis and alarm functions. Once it detects abnormal equipment operation or parameters exceeding the set range, it can immediately issue an alarm and take appropriate protective measures to ensure the safety of equipment and personnel. In addition, the intelligent control system can also store and analyze historical data from the extraction process, providing strong support for process optimization, quality traceability, etc., and helping to continuously improve extraction technology and drug solution quality.

[0046] Example 2

[0047] like Figures 1-9 As shown, an extraction device is set up based on the extraction system of the liquid for treating skin wounds. The pretreatment module includes a carrying component 1 for stabilizing the raw material. One end of the carrying component 1 is connected to a grinding component 3 for preliminary crushing of the raw material, and a crushing component 2 for crushing the raw material is rotated inside the carrying component 1. After the raw material enters the carrying component 1, it is first preliminarily divided by the crushing component 2, and the divided raw material is prompted to enter the grinding component 3 for secondary crushing to ensure that the raw material can be fully mixed with the solution. The grinding component 3 is connected to an extraction component 4 at one end away from the crushing component 2. The raw materials crushed by the crushing component 2 enter the extraction component 4. The extraction component 4 is connected to a mixing component 5 for stirring the raw materials and the solution in the extraction component 4. When in use, the raw materials to be processed are first introduced into the carrying component 1, and then the crushing component 2 is used to perform preliminary crushing on the raw materials so that they fall into the grinding component 3. At this time, the grinding component 3 is controlled according to the mixing requirements of the raw materials, and the grinding component 3 is used to perform secondary grinding on the crushed raw materials so that the ground raw materials enter the extraction component 4, and the mixing component 5 is used to stir the mixed liquid in the extraction component 4 to ensure that it meets the mixing requirements.

[0048] The supporting component 1 includes a shell 101. In order to ensure that all the raw materials can enter the grinding component 3, in the present invention, the shell 101 is set to a cone shape, and a supporting cavity 103 for raw material crushing is opened in the shell 101. A filter plate 102 is connected to the inner wall of the supporting cavity 103, wherein one end of the filter plate 102 is fixedly connected to the cavity wall of the supporting cavity 103, and the remaining area does not contact the cavity wall of the supporting cavity 103, that is, there is a gap between the filter plate 102 and the cavity wall of the supporting cavity 103, and the filter plate 102 can contact the crushing component 2. In the process of grinding the raw material, the crushing component 2 and the filter plate 102 conflict with each other and move relative to each other, so as to achieve rapid crushing of the raw material, and the crushed raw material passes through the filter plate 102 and enters the grinding component 3.

[0049] In order to effectively fix the crushing assembly 2, a support rod 104 is connected to the end of the shell 101 away from the grinding assembly 3. The crushing assembly 2 is connected to the support rod 104 to ensure the stability of the crushing assembly 2 during operation.

[0050] The crushing assembly 2 includes a rotating rod 202 for driving the crushing assembly 2 to work, one end of the rotating rod 202 passes through and is rotatably connected to the support rod 104, and a driving motor 201 is provided on one end of the rotating rod 202 passing through the support rod 104 for providing power to the rotating rod 202, and a plurality of crushing rods 203 are connected to the outer circumference of the rotating rod 202, and the crushing rods 203 can interfere with the filter plate 102, so that when in use, the angle of the crushing rod 203 is controlled to be consistent with the inclination angle of the filter plate 102, so that the crushing rod 203 can completely interfere with the filter plate 102, and then the crushing rod 203 and the filter plate 102 are driven by the rotation of the rotating rod 202 to move relative to each other, ensuring the stability of the raw material during the crushing process, and a liquid outlet component 6 for replenishing the solution is connected to the rotating rod 202, and the liquid outlet component 6 can clean the residual raw material on the carrying component 1 when replenishing the solution in the extraction component 4.

[0051] Furthermore, in order to ensure that the crushing rod 203 cooperates with the filter plate 102 to achieve the crushing of Chinese herbal medicine, the crushing rod 203 includes a movable rod 2031. In the present invention, the movable rod 2031 can be set to a rod with a fixed length, and the movable rod 2031 can also be set to a telescopic state. In the present invention, it is preferred to set the movable rod 2031 to a telescopic state to ensure that the length of the movable rod 2031 can cause the crushing block 2032 to conflict with the filter plate 102. One end of the movable rod 2031 is connected to the rotating rod 202, and the other end of the movable rod 2031 is rotatably connected to the crushing block 2032. By rotating the crushing block 2032, the crushing block 2032 is brought close to the filter plate 102 without directly contacting it, ensuring that the Chinese herbal medicine can be moved between the crushing block 2032 and the filter plate 102, and the end of the crushing block 2032 away from the movable rod 2031 is movably provided with a cutting blade, that is, the crushing block 2032 and the cutting blade are controlled by an electric slide rail, and the length extension direction of the cutting blade is the same as the rotation direction of the rotating rod 202, and the end of the crushing block 2032 away from the movable rod 2031 can conflict with the filter plate 102, thereby achieving preliminary crushing of the raw materials.

[0052] During use, when the crushing block 2032 rotates with the movable rod 2031, the crushing block 2032 and the cutting blade respectively move intermittently, that is, when the rotating rod 202 initially rotates, the cutting blade is stored in the crushing block 2032 and has no direct contact with the Chinese herbal medicine. The Chinese herbal medicine is squeezed and crushed by utilizing the gap between the crushing block 2032 and the filter plate 102. After the rotating rod 202 rotates five times, the cutting blade is controlled to extend from the crushing block 2032, prompting the cutting blade to cut the Chinese herbal medicine. Subsequently, after the rotating rod 202 rotates five times, the cutting blade is stored in the crushing block 2032. This working rule realizes the initial crushing and cutting of the Chinese herbal medicine, thereby improving its crushing efficiency.

[0053] During the operation of the movable rod 2031 and the crushing block 2032, the distance between the crushing block 2032 and the filter plate 102 is controlled by changing the length of the movable rod 2031, thereby controlling the grinding efficiency of the crushing block 2032 during the grinding process, and preventing the crushed raw material residue from being too adherent to the filter plate 102, which is not conducive to subsequent cleaning.

[0054] Furthermore, in order to ensure that the liquid outlet component 6 can release different types of solutions according to different raw materials, the liquid outlet component 6 includes a liquid storage tray 602 for transferring the solution. The liquid storage tray 602 is fixedly connected to the rotating rod 202. When the rotating rod 202 rotates, it can drive the liquid storage tray 602 to rotate synchronously. The liquid storage tray 602 is connected to a liquid inlet pipe 601 for the entry of the solvent. The end of the liquid inlet pipe 601 away from the liquid storage tray 602 is connected to the outside, that is, connected to different solvent tanks. The solvent is introduced into the liquid storage tray using the liquid inlet pipe 601 according to the use requirements. In 602, a plurality of spray ports 603 for discharging the solvent are provided on the circumference of the liquid storage tray 602, so that the spray ports 603 can introduce the solvent in the liquid storage tray 602 into the carrying cavity 103. It should be noted that there is a height difference between the liquid outlet component 6 and the crushing rod 203, which will not interfere with the operation of the crushing rod 203. The spray ports 603 can release small doses according to the crushing conditions of the crushing blocks 2032 to alleviate the temperature in the carrying cavity 103. After the Chinese herbal medicine has completely passed through the carrying cavity 103, a large dose of solvent will be released.

[0055] Furthermore, due to the different types of skin injuries, the grinding degree of the raw materials is different when preparing different medicinal solutions, and the grinding assembly 3 includes a grinding box 301 for secondary crushing of the raw materials. The grinding box 301 is detachably connected to the shell 101, so as to facilitate the disassembly and installation of the device. A grinding chamber 302 for secondary crushing of the raw materials is provided in the grinding box 301. The grinding chamber 302 is communicated with the bearing chamber 103 to ensure that the raw materials passing through the bearing chamber 103 can enter the grinding chamber 302, and a discharge port 3011 is provided at one end of the grinding chamber 302 away from the bearing chamber 103. The discharge port 3011 is connected to the bearing chamber 103. The extraction chambers 403 are interconnected and are used to input the raw materials ground by the grinding assembly 3 into the extraction chamber 403. A screening assembly 303 for secondary crushing of the raw materials is connected to the grinding chamber 302. The raw materials falling into the grinding chamber 302 can fall onto the screening assembly 303, ensuring that the screening assembly 303 can meet the secondary grinding of the raw materials. A rotating rod 304 is connected to the end of the screening assembly 303 away from the shell 101. The rotating rod 304 is rotated to drive the rotating disk 3031 in the screening assembly 303 to rotate, thereby achieving uniform grinding of the raw materials. At the same time, the centrifugal force generated by the rotation is used to drive the raw materials to move on the rotating disk 3031.

[0056] Furthermore, in order to ensure that the screening component 303 can be moved out of the screening component 303 while meeting the secondary crushing, the screening component 303 includes a rotating disk 3031, one end of the rotating disk 3031 is connected to the rotating rod 304, and the rotating disk 3031 is driven to rotate by the rotating rod 304. The side of the rotating disk 3031 away from the rotating rod 304 is connected with an extrusion plate 3032. In order to ensure that the raw materials can fall on the rotating disk 3031 in the screening component 303, the shape of the extrusion plate 3032 is set to be annular in the present invention, and the middle part of the annular is aligned with the bearing cavity 103 and the grinding cavity. 302 corresponds to the connection point, ensuring that the raw materials entering the grinding chamber 302 can pass through the ring and fall onto the rotating disk 3031. The end of the extrusion plate 3032 away from the rotating disk 3031 is connected to a plurality of telescopic rods 3033 for adjusting the position of the extrusion plate 3032. The end of the telescopic rod 3033 away from the extrusion plate 3032 is connected to the cavity wall of the grinding chamber 302. According to the size of the crushed particle size of the raw material, the length of the telescopic rod 3033 is adjusted to adjust the distance between the extrusion plate 3032 and the rotating disk 3031, thereby controlling the screening particle size of the raw materials passing through the screening component 303 to meet the requirements of the liquid medicine preparation process.

[0057] Furthermore, in order to ensure that the components of the ground medicinal liquid can be effectively extracted and meet the use requirements for skin wounds, the extraction component 4 includes an extraction box 401 for mixing and storing medicinal liquids, and an extraction chamber 403 is provided in the extraction box 401 for receiving the raw materials passing through the grinding component 3. The extraction chamber 403 is connected to one end of the grinding component 3 with a feed port 4011, wherein in order to match the discharge position of the rotating disk 3031, the feed port 4011 is set to be annular, and the radius of the ring is adapted to the radius of the rotating disk 3031, and the feed port 4011 is connected to the grinding chamber 302. The extraction box 401 is respectively provided with a liquid outlet 402 and a slag outlet 404, wherein the liquid outlet 402 is used to discharge the mixed solution, and the slag outlet 404 is used to remove the raw material residue in the solution, and the mixing component 5 is rotatably connected to the extraction chamber 403, and the rotation of the mixing component 5 is utilized to promote the rapid mixing of the solution and the raw material in the extraction chamber 403.

[0058] Furthermore, in order to increase the mixing speed of the raw materials in the extraction chamber 403, the mixing assembly 5 includes a driving rod 501, one end of the driving rod 501 is rotatably connected to the top wall of the extraction chamber 403, and the driving rod 501 is used to drive the mixing assembly 5 to rotate, so as to achieve stirring of the solution in the extraction chamber 403. A movable disk 502 is slidingly provided on the side of the driving rod 501 close to the grinding assembly 3, and the movable disk 502 can move back and forth along the driving rod 501. A connecting rod 504 is rotatably provided on the movable disk 502, and an end of the driving rod 501 away from the grinding assembly 3 is connected to a supporting disk 503, and a stirring rod 505 is rotatably provided on the supporting disk 503. The connecting rod 504 and the stirring rod 505 are close to each other and are connected to a mixing plate 506. The rotation of the plate 506 realizes the stirring of the solution in the extraction chamber 403, wherein the lengths of the connecting rod 504 and the stirring rod 505 can be adjusted, so that the angle of the mixing plate 506 in the extraction chamber 403 can be adjusted. When the mixing plate 506 is in the mixing process, the lengths of the connecting rod 504 and the stirring rod 505 are the same. At this time, the mixing plate 506 is in the middle area of ​​the movable disk 502 and the support disk 503. When the mixing is completed, the movable disk 502 is controlled to move toward one end close to the support disk 503, and at the same time, the length of the stirring rod 505 is controlled to shorten and the length of the connecting rod 504 is extended, so that the end face of the mixing plate 506 is flush with the plane of the support disk 503, and the raw material residue area in the extraction chamber 403 is compressed, so that the residue is separated from the solution, which is convenient for separating and extracting the mixed liquid medicine.

[0059] It should be noted that, according to actual usage requirements, a supplementary plate for increasing the range of the mixing plate 506 can be provided in the mixing plate 506, wherein the mutual cooperation between the mixing plate 506 and the supplementary plate can completely cover the extraction chamber 403, thereby preventing raw material residues from interfering with the extraction of the medicinal solution.

[0060] Furthermore, one end of the rotating disk 3031 close to the extrusion plate 3032 is an arc-shaped surface, so that the medicine liquid is concentrated in the area of ​​the rotating disk 3031, so that when the rotating disk 3031 rotates, the raw materials on the rotating disk 3031 are moved evenly, thereby improving the accuracy of grinding.

[0061] In order to further improve the mixing efficiency of the mixing plate 506 in mixing the solution in the extraction chamber 403 , a pressure sensor for receiving the stirring pressure during stirring is provided on the mixing plate 506 .

[0062] During operation, the raw materials to be processed are first pre-processed and then placed in the carrying assembly 1. At the same time, the movable rod 2031 is controlled to move and the angle of the crushing block 2032 is controlled to correspond to the inclination angle of the filter plate 102. Then, the drive motor 201 is controlled to work, driving the rotating rod 202 to rotate, prompting the crushing rod 203 to rotate, so that the crushing block 2032 and the filter plate 102 slide relative to each other, thereby prompting the raw materials between the crushing block 2032 and the filter plate 102 to have relative friction and extrusion with the filter plate 102, so that large pieces of raw materials are broken and pass through the aperture of the filter plate 102, thereby passing through the carrying cavity 103 into the grinding cavity 302 and falling into the depression of the rotating disk 3031.

[0063] According to the needs of preparing the medicinal solution, the particle size of the solution when extracting the medicinal components in the raw materials is identified, and the length of the telescopic rod 3033 is controlled to change, which drives the distance between the extrusion plate 3032 and the rotating disk 3031 to change, thereby controlling the grinding particle size of the crushed raw materials in the grinding assembly 3. When the distance between the extrusion plate 3032 and the rotating disk 3031 is large, the grinding particle size of the raw materials is large, and vice versa, the grinding particle size of the raw materials is small.

[0064] When the crushed raw material falls onto the rotating disk 3031, the working state of the crushing component 2 is maintained unchanged, and the rotating rod 304 is controlled to rotate, driving the rotating disk 3031 to rotate. The centrifugal force causes relative movement between the raw material and the rotating disk 3031. At the same time, friction occurs between the extrusion plate 3032 during the movement, thereby achieving further grinding of the crushed raw material. During the grinding process of the grinding component 3, the raw material crushed by the crushing component 2 can continuously fall on the rotating disk 3031, ensuring the normal grinding of the grinding component 3, and the ground raw material flows out from the circumference of the rotating disk 3031 and enters the extraction chamber 403.

[0065] In the above process, the solution mixed with the raw material is released through the liquid outlet component 6, that is, the solution to be released is introduced into the liquid storage tray 602 through the liquid inlet pipe 601, and then released through the spray port 603, so that the liquid medicine passes through the supporting component 1 and the grinding component 3 in turn and enters the extraction component 4 to be mixed and extracted with the ground raw material. In this process, the flushing force of the solution is used to clean the cavity wall of the supporting cavity 103, the filter plate 102 and the screening component 303 to prevent the raw material from remaining and adhering to the device.

[0066] At this time, the mixing plate 506 is located in the middle position between the movable plate 502 and the supporting plate 503. The driving rod 501 is controlled to rotate, driving the connecting rod 504, the stirring rod 505 and the mixing plate 506 to rotate in the extraction chamber 403, so as to achieve mixing and stirring of the solution in the extraction chamber 403, ensuring that the solution in the extraction chamber 403 and the crushed raw material are fully mixed and contacted. At the same time, during the mixing process, in order to prevent excessive precipitation of raw material residue in the extraction chamber 403 and affect the contact between the raw material and the solution, the angles and lengths of some connecting rods 504 and the stirring rod 505 can be regularly adjusted during the rotation of the mixing plate 506, thereby driving the position height of the mixing plate 506 in the extraction chamber 403 to change, thereby meeting the requirements of stirring the raw materials in various areas of the extraction chamber 403 and promoting the rapid generation of the medicinal solution. When the mixing assembly 5 stirs and mixes the raw materials and the solvent in the extraction chamber 403, the intelligent control system accurately controls the extraction parameters such as temperature, pressure, stirring speed and solvent flow, thereby achieving multi-stage solvent extraction and improving the extraction rate of the effective component.

[0067] When the raw material increases to the target value and the amount of solution released by the liquid outlet component 6 reaches the release amount, the liquid outlet component 6 is stopped from releasing liquid, and the raw material will no longer be added to the carrier component 1.

[0068] When the medicinal liquid in the extraction chamber 403 is mixed, the movable disk 502 is controlled to move along the driving rod 501, driving the connecting rod 504 and the stirring rod 505 to rotate. At the same time, the length of the connecting rod 504 is extended and the length of the stirring rod 505 is shortened, prompting the plate surface of the mixing plate 506 to be flush with the end face of the support disk 503, compressing the raw material residue to the end of the support disk 503 away from the grinding component 3, avoiding the raw material residue from affecting the discharge efficiency of the medicinal liquid, and in the process of deflection and slow movement of the mixing plate 506, the mixing plate 506 moves the large pieces of raw material residue in the extraction chamber 403 to the end away from the grinding component 3, reducing the blockage of the liquid outlet 402 by the raw material residue, and improving the collection rate of the medicinal liquid.

[0069] After the mixing plate 506 moves to the target position, the liquid outlet 402 is controlled to be connected with the extraction chamber 403, and the mixed liquid medicine is discharged from the extraction chamber 403 for storage, and then the slag outlet 404 is opened to take out the remaining raw material residue from the extraction chamber 403. It should be noted that a filter net is provided at the slag outlet 404 for filtering the fine residue of the raw material.

[0070] During the process of mixing and stirring the solution using the mixing assembly 5, the working status of the mixing plate 506 is identified by the pressure sensor. When the pressure sensors on the mixing plates 506 detect that the stirring pressures of the various mixing plates 506 are the same or nearly the same, this means that the particle size of the raw materials ground by the crushing assembly 2 and the grinding assembly 3 is the same, which facilitates sufficient mixing of the raw materials. When the pressure sensors on the various mixing plates 506 show obvious numerical differences, the position of the mixing plate 506 in the extraction chamber 403 is read. If the mixing plate 506 is located close to the slag outlet 404, it means that the raw materials have precipitated in the extraction chamber 403, and the crushing assembly 2 and the grinding assembly 3 have not fully mixed the raw materials, and they need to be shut down for maintenance. If the mixing plate 506 is located far from the slag outlet 404, it means that the raw materials have agglomerated during the mixing process. It is necessary to control the rotation speed of the driving rod 501 to increase the stirring speed of the solution, thereby achieving the crushing of the agglomerated raw materials, increasing the contact area between the raw materials and the solution, and ensuring the stability of the efficacy of the liquid medicine.
