Description

Technical Field

[0001] The present invention belongs to the technical field of liquid medicine extraction, and specifically relates to an extraction system and extraction equipment for a liquid medicine for treating skin wounds. Background Art

[0002] When extracting a liquid medicine for treating skin wounds, it is usually necessary to crush plant tissues or Chinese herbal medicines with therapeutic effects and then mix them with corresponding solutions. Moreover, during the liquid medicine extraction process, the pretreatment of raw materials is not sufficient, resulting in incomplete extraction of active ingredients and affecting the efficacy of the liquid medicine. In addition, when existing equipment processes different types of plant raw materials, it is often difficult to flexibly adjust process parameters.

[0003] The patent with the application number CN202410634527.3 discloses a grinding equipment for traditional Chinese medicine extraction and a grinding method for traditional Chinese medicine liquid extraction, including a body component, a protection component, a power component, a transmission component, and a grinding component. The grinding component internally includes a first grinding wheel and a second grinding wheel for grinding. The rotational speeds of the first grinding wheel and the second grinding wheel are different, and the rotational directions of the first grinding wheel and the second grinding wheel are opposite. The grinding component also includes an annular net for blocking larger traditional Chinese medicines from passing through and a grinding ring for powdered traditional Chinese medicines to pass through. The grinding ring is inserted into the annular net. The above solution uses two grinding wheels to cooperate concentrically, and there are grinding sheets on the grinding wheels. By having the two grinding wheels rotate in opposite directions, the traditional Chinese medicines are continuously collided between the grinding wheels, and grinding will also occur between the second grinding wheel and the grinding ring, making the grinding rate faster and the efficiency higher. Although the above improves the grinding rate of traditional Chinese herbal medicines, during the grinding process, it is impossible to perform corresponding grinding and crushing according to different types of traditional Chinese herbal medicines, thus affecting the mixing efficiency of traditional Chinese herbal medicines and solutions and the use effect of the extracted liquid medicine.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

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

[0041] The pretreatment module is used for cleaning and crushing raw materials. Through precise crushing and drying processes, 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] Multi-stage solvent extraction module, which is used to contact the solvent with the pretreated plant raw materials in the extraction component 4 under sufficient stirring, 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 flow, solvents with different polarities enter each extraction tank through the solvent inlet in turn, and contact with the pretreated plant raw materials under sufficient stirring of the stirring device, so that the active ingredients are continuously dissolved in the solvent. By accurately controlling parameters such as the temperature, pressure, stirring speed and solvent flow rate of each extraction tank through the intelligent control system, the automation and precision operation of multi-stage solvent extraction are realized. The multi-stage extraction method can target the extraction of active ingredients with different polarities and solubilities, maximize the extraction rate of active ingredients, and avoid the problem of incomplete extraction caused by traditional single-solvent extraction;

[0043] Separation and purification module, which realizes the efficient separation and purification of the extract by combining membrane separation and chromatographic separation, initially realizes solid-liquid separation and removal of macromolecular impurities. The separation and purification process is carried out in a closed system, effectively preventing external pollution and ensuring the sterility of the medicinal liquid;

[0044] Medicinal liquid preparation module, which is used to achieve accurate preparation of the medicinal liquid, ensure the consistency of the quality and composition of each batch of medicinal liquid, and meet the personalized treatment needs under different clinical application scenarios. At the stage of medicinal liquid preparation, according to the type, severity and treatment needs of skin trauma, the formula parameters of the medicinal liquid are preset through the intelligent control system, including the concentration of different active ingredients, the type and dosage of the solvent, the proportion of additives, etc. After the extract is separated and purified, it is mixed with the solvent and additives evenly according to the set formula ratio through the medicinal liquid transportation under sufficient stirring of the stirring device to form the final medicinal liquid for treating skin trauma. The medicinal liquid preparation module can achieve accurate preparation of the medicinal liquid, ensure the consistency of the quality and composition of each batch of medicinal liquid, and meet the personalized treatment needs under different clinical application scenarios;

[0045] Intelligent control system, which is used for the fully automatic and intelligent operation of the equipment, improving the production efficiency and the stability of product quality. The intelligent control system realizes the fully automatic and intelligent operation of the extraction equipment, greatly improving the production efficiency and the stability of product quality. By pre-writing a complete control program, it can accurately control every link in the extraction process, ensure the accurate execution of the extraction process, and avoid the influence of human operation errors on the extraction effect. At the same time, the system has an automatic fault diagnosis and alarm function. Once it detects that the equipment is operating abnormally or the parameters exceed the set range, it can immediately issue an alarm and take corresponding protection measures to ensure the safety of the equipment and personnel. In addition, the intelligent control system can also store and analyze the historical data in the extraction process, providing strong support for process optimization, quality traceability, etc., and helping to continuously improve the extraction technology and the quality of the medicinal liquid.

[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, so as to control the grinding efficiency of the crushing block 2032 during the grinding process, preventing excessive adhesion between the crushed raw material residue and the filter plate 102, which is not conducive to subsequent cleaning.

[0054] Furthermore, to ensure that the liquid outlet assembly 6 can release different types of solutions according to different raw materials, the liquid outlet assembly 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. An inlet pipe 601 for the solvent to enter is connected to the liquid storage tray 602. The end of the inlet pipe 601 away from the liquid storage tray 602 is connected to the outside, that is, to different solvent tanks. According to the usage requirements, the solvent is introduced into the liquid storage tray 602 through the inlet pipe 601. A plurality of spraying ports 603 for discharging the solvent are formed through the circumference of the liquid storage tray 602, so that the spraying ports 603 introduce the solvent in the liquid storage tray 602 into the bearing cavity 103. It should be noted that there is a height difference between the liquid outlet assembly 6 and the crushing rod 203, which will not interfere with the operation of the crushing rod 203. Among them, the spraying ports 603 can release small doses according to the crushing situation of the crushing block 2032 to relieve the temperature in the bearing cavity 103. After the Chinese herbal medicine completely passes through the bearing cavity 103, a large dose of solvent is released.

[0055] Furthermore, due to the different types of skin wounds, when preparing different liquid medicines, the grinding degree of the raw materials is also different. Therefore, 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 housing 101, which is convenient for disassembly and installation of the device. A grinding cavity 302 for secondary crushing of the raw materials is provided in the grinding box 301. The grinding cavity 302 is connected to the bearing cavity 103 to ensure that the raw materials passing through the bearing cavity 103 can enter the grinding cavity 302. An outlet 3011 is provided at the end of the grinding cavity 302 away from the bearing cavity 103. The outlet 3011 is interconnected with the extraction cavity 403 to input the raw materials ground by the grinding assembly 3 into the extraction cavity 403. A screening assembly 303 for secondary crushing of the raw materials is connected in the grinding cavity 302. The raw materials falling into the grinding cavity 302 can fall onto the screening assembly 303 to ensure that the screening assembly 303 can meet the requirements for secondary grinding of the raw materials. A rotating rod 304 is connected to the end of the screening assembly 303 away from the housing 101. By rotating the rotating rod 304, the rotating disk 3031 in the screening assembly 303 is driven to rotate, realizing uniform grinding of the raw materials, and at the same time driving the raw materials to move on the rotating disk 3031 by the centrifugal force formed by the rotation.

[0056] Further, to ensure that while the screening component 303 meets the requirements of secondary crushing, the raw materials can also be removed from the screening component 303. Thus, 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 rod 304 is used to drive the rotation of the rotating disk 3031. On the side of the rotating disk 3031 away from the rotating rod 304, an extrusion plate 3032 is connected. In order to ensure that the raw materials can fall onto the rotating disk 3031 in the screening component 303, in the present invention, the shape of the extrusion plate 3032 is set as an annular shape, and the middle of the ring corresponds to the connection between the bearing cavity 103 and the grinding cavity 302, ensuring that the raw materials entering the grinding cavity 302 can pass through the ring and fall onto the rotating disk 3031. At the end of the extrusion plate 3032 away from the rotating disk 3031, a plurality of telescopic rods 3033 for regulating the position of the extrusion plate 3032 are connected. The end of the telescopic rod 3033 away from the extrusion plate 3032 is connected to the cavity wall of the grinding cavity 302. According to the size of the crushed particle size of the raw materials, the length of the telescopic rod 3033 is regulated, thereby regulating the distance between the extrusion plate 3032 and the rotating disk 3031, and thus controlling the screening particle size of the raw materials passing through the screening component 303 to meet the requirements in the preparation process of the medicinal liquid.

[0057] Further, to ensure that the components of the medicinal liquid after grinding can be effectively extracted to meet the usage requirements for skin wounds, thus the extraction component 4 includes an extraction tank 401 for storing the mixed medicinal liquid. An extraction cavity 403 for receiving the raw materials passing through the grinding component 3 is provided in the extraction tank 401. At one end of the extraction cavity 403 close to the grinding component 3, a feed inlet 4011 is connected. In order to cooperate with the discharging position of the rotating disk 3031, the feed inlet 4011 is set as an annular shape, and the radius of the ring is adapted to the radius of the rotating disk 3031. The feed inlet 4011 is communicated with the grinding cavity 302. The extraction tank 401 is respectively provided with a liquid outlet 402 and a slag outlet 404 penetrating through it. The liquid outlet 402 is used for discharging the mixed solution, and the slag outlet 404 is used for removing the raw material residues in the solution. And the mixing component 5 is rotatably connected in the extraction cavity 403, and the rotation of the mixing component 5 is used to promote the rapid mixing of the solution and the raw materials in the extraction cavity 403.

[0058] Further, in order to improve 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 chamber of the extraction chamber 403. The driving rod 501 is used to drive the mixing assembly 5 to rotate, so as to realize the stirring of the solution in the extraction chamber 403. A movable disk 502 is slidably arranged on the side of the driving rod 501 close to the grinding assembly 3. The movable disk 502 can reciprocate along the driving rod 501. A connecting rod 504 is rotatably arranged on the movable disk 502. One end of the driving rod 501 away from the grinding assembly 3 is connected with a support disk 503. A stirring rod 505 is rotatably arranged on the support disk 503. A mixing plate 506 is connected to the ends of the connecting rod 504 and the stirring rod 505 close to each other. The rotation of the connecting rod 504, the stirring rod 505 and the mixing plate 506 realizes the stirring of the solution in the extraction chamber 403. The lengths of the connecting rod 504 and the stirring rod 505 can be adjusted, so as to control the angle of the mixing plate 506 in the extraction chamber 403 to be adjusted. When the mixing plate 506 is mixing, 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 between the movable disk 502 and the support disk 503. After the mixing is completed, the movable disk 502 is controlled to move towards one end close to the support disk 503, and at the same time, the length of the stirring rod 505 is shortened and the length of the connecting rod 504 is elongated, so as to make the end face of the mixing plate 506 flush with the plane of the support disk 503, compress the raw material residue area in the extraction chamber 403, and promote the separation of the residue and the solution, which is convenient for the separation and extraction of the mixed liquid medicine.

[0059] It should be noted that according to the actual use requirements, a supplementary plate for increasing the range of the mixing plate 506 can be arranged in the mixing plate 506. The mutual cooperation between the mixing plate 506 and the supplementary plate can completely cover the extraction chamber 403, avoiding the interference of raw material residues on the extraction of the liquid medicine.

[0060] Further, one end of the rotating disk 3031 close to the pressing plate 3032 is an arc surface, so that the liquid medicine is concentrated in the area of the rotating disk 3031. Thus, when the rotating disk 3031 rotates, the raw materials on the rotating disk 3031 move evenly, improving the accuracy of grinding.

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

[0062] During operation, first, the raw materials to be processed are pre-treated and then placed into the loading component 1. Meanwhile, the movement of the movable rod 2031 and the angle of the crushing block 2032 are controlled to correspond to the inclination angle of the filter plate 102. Then, the driving motor 201 is controlled to operate, driving the rotating rod 202 to rotate, which in turn causes the crushing rod 203 to rotate, resulting in relative sliding between the crushing block 2032 and the filter plate 102. Consequently, relative friction and extrusion occur between the raw materials between the crushing block 2032 and the filter plate 102 and the filter plate 102, causing the large pieces of raw materials to break and pass through the apertures of the filter plate 102, thereby passing through the loading cavity 103 and entering the grinding cavity 302, and falling into the recesses of the rotating disk 3031.

[0063] According to the requirements for preparing the liquid medicine, the particle size of the solution during the extraction of medicinal components from the raw materials is identified, and the length of the telescopic rod 3033 is controlled to change, driving 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 component 3. When the distance between the extrusion plate 3032 and the rotating disk 3031 is relatively large, the grinding particle size of the raw materials is relatively large; conversely, the grinding particle size of the raw materials is relatively small.

[0064] When the crushed raw materials fall 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. Under the action of centrifugal force, relative movement occurs between the raw materials and the rotating disk 3031, and at the same time, friction occurs with the extrusion plate 3032 during the movement process, realizing further grinding of the crushed raw materials. During the grinding process of the grinding component 3, the raw materials crushed by the crushing component 2 can continuously fall onto the rotating disk 3031, ensuring the normal grinding of the grinding component 3, and the ground raw materials flow out from the circumference of the rotating disk 3031 and enter the extraction cavity 403.

[0065] Moreover, during the above process, the solution mixed with the raw materials 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 spraying port 603, so that the liquid medicine passes through the loading component 1 and the grinding component 3 in sequence and then enters the extraction component 4 to be mixed and extracted with the ground raw materials. And during this process, the cleaning of the cavity wall of the loading cavity 103, the filter plate 102, and the screening component 303 is carried out by using the scouring force of the solution to prevent the raw materials from remaining and adhering to the device.

[0066] At this time, the mixing plate 506 is located at the middle position between the movable plate 502 and the support plate 503. Control the driving rod 501 to rotate, drive the connecting rod 504, the stirring rod 505 and the mixing plate 506 to rotate in the extraction chamber 403, so as to realize the mixing and stirring of the solution in the extraction chamber 403, ensure that the solution in the extraction chamber 403 is fully mixed and contacted with the crushed raw materials. At the same time, during the mixing process, in order to prevent the raw material residues from excessively precipitating in the extraction chamber 403 and affecting the contact between the raw materials and the solution, during the rotation of the mixing plate 506, the angles and lengths of some connecting rods 504 and stirring rods 505 can be adjusted regularly, so as to drive the position height of the mixing plate 506 in the extraction chamber 403 to change, so as to meet the stirring of the raw materials in various areas of the extraction chamber 403, promote the rapid generation of the medicinal liquid. And when the mixing component 5 stirs and mixes the raw materials and solvents in the extraction chamber 403, the extraction parameters such as temperature, pressure, stirring speed and solvent flow rate are accurately controlled through the intelligent control system to realize multi-stage solvent extraction and improve the extraction rate of the active ingredients.

[0067] When the raw materials increase to the target value and the amount of the solution released through the liquid outlet component 6 reaches the release amount, at this time, stop the liquid outlet component 6 from continuing to release the liquid, and no more raw materials will be added to the loading component 1.

[0068] When the mixing of the medicinal liquid in the extraction chamber 403 is completed, at this time, control the movable plate 502 to move along the driving rod 501. While driving the connecting rod 504 and the stirring rod 505 to rotate, the length of the connecting rod 504 extends, and the length of the stirring rod 505 shortens, so that the plate surface of the mixing plate 506 is flush with the end surface of the support plate 503, and the raw material residues are compressed to one end of the support plate 503 away from the grinding component 3, so as to prevent the raw material residues from affecting the discharge efficiency of the medicinal liquid. And during the deflection and slow movement of the mixing plate 506, the mixing plate 506 moves the large raw material residues in the extraction chamber 403 to one end away from the grinding component 3, reduces the blockage of the liquid outlet 402 by the raw material residues, and improves the collection rate of the medicinal liquid.

[0069] After the mixing plate 506 moves to the target position, control the liquid outlet 402 to communicate with the extraction chamber 403, discharge the mixed medicinal liquid from the extraction chamber 403 for storage, and then open the residue outlet 404 to take out the remaining raw material residues from the extraction chamber 403. It should be noted that a filter screen for filtering fine raw material residues is provided at the residue outlet 404.

[0070] During the process of mixing and stirring the solution by using the mixing component 5, the working condition of the mixing plate 506 is identified through a pressure sensor. When the stirring pressures detected by the pressure sensors on each mixing plate 506 are the same or approximately the same, it means that the particle sizes of the raw materials ground by the crushing component 2 and the grinding component 3 are the same, which is convenient for the full mixing of the raw materials. When there are obvious numerical differences in the pressure sensors on each mixing plate 506, the position of the mixing plate 506 in the extraction chamber 403 is read at this time. If the position of the mixing plate 506 is close to the slag outlet 404, it means that there is precipitation of the raw materials in the extraction chamber 403, and the crushing component 2 and the grinding component 3 do not fully mix the raw materials, and it is necessary to stop the machine for maintenance. If the position of the mixing plate 506 is far from the slag outlet 404, it means that during the mixing process, there is a situation where the raw materials agglomerate. It is necessary to control the rotation speed of the driving rod 501 to increase and improve the stirring speed of the solution, so as to break the agglomerated raw materials, increase the contact area between the raw materials and the solution, and ensure the stable efficacy of the medicinal liquid.
