Description

Technical Field

[0001] The present invention relates to the technical field of oil vitamin extraction, and specifically to an extraction device dedicated to extracting oil vitamins. Background Art

[0002] Solid-phase extraction technology is increasingly widely used in the extraction of oil vitamins. Its principle is based on the distribution difference of the target substance between the solid-phase adsorbent and the sample solution to achieve the separation and enrichment of the target vitamin. However, a series of problems that seriously affect the extraction effect and efficiency have emerged in the actual operation process of the existing technology.

[0003] In the prior art, the operation process of the solid-phase extraction instrument is extremely cumbersome, and a large number of links rely on manual intervention; starting from the pre-experiment preparation, the operator needs to manually complete the accurate measurement and configuration of various reagents. Any deviation will affect the subsequent extraction results; in the sample processing stage, manual operation is not only time-consuming and laborious, but also easily leads to differences between samples due to inconsistent operation methods.

[0004] At the same time, in the process of installing the extraction column, due to the lack of an effective auxiliary positioning device, it entirely depends on the operator's experience and visual judgment to ensure the vertical installation of the extraction column; this method has great uncertainty. If care is not taken, the column body will tilt. Once the column body tilts, the flow path inside the extraction column will become extremely complex and uneven; when the solution flows in the column, the flow velocity differences in different parts are significant, making it difficult to unify the contact time and degree between the target substance and the adsorbent, resulting in a large fluctuation in the extraction efficiency and unable to ensure a stable and high-quality extraction effect; the tilted column body will also cause the adsorbent packing to shift and redistribute under the action of gravity, damaging the originally tight and uniform packing structure. Some areas are over-packed, hindering the solution flow, and some areas become sparse, reducing the adsorption capacity, thereby seriously damaging the performance of the adsorbent and significantly shortening its service life; in addition, the tilted installation will also apply additional stress to the connection part between the extraction column and the instrument, which is extremely likely to cause seal failure and leakage problems in the long term. Leakage not only causes waste of valuable samples and expensive reagents, pollutes the experimental environment, but also corrodes and damages the instrument equipment, increasing the maintenance cost and downtime.

[0005] In addition, during the activation and elution processes of the extraction column, precise control of the solution flow rate is crucial. However, currently, the flow rate is mainly adjusted manually by turning a knob, which is greatly affected by the subjective factors of the operator and it is difficult to achieve stable and precise flow rate control. Unstable flow rates can lead to inconsistent contact times between the solvent and the target substance. When the flow rate is too fast, the target substance cannot be fully adsorbed or eluted, resulting in a reduced recovery rate. When the flow rate is too slow, the entire extraction cycle is prolonged, reducing work efficiency. Unstable flow rates can also cause irregular fluctuations in the elution curve, making it difficult for operators to accurately determine the elution timing, increasing the difficulty of collecting high-purity target substances, and even causing impurities to be eluted together with the target substance, seriously interfering with subsequent analysis and detection work, leading to deviations in experimental results and being unable to truly reflect the actual content and properties of oil-soluble vitamins in the sample.

[0006] In summary, when the existing solid-phase extraction instrument is used for the extraction of oil-soluble vitamins, due to the cumbersome operation, high manual participation, and the lack of precise control means for key links, it severely restricts the efficient and stable development of the extraction work. There is an urgent need to develop a new technical solution to overcome these problems and improve the overall level of oil-soluble vitamin extraction.

[0007] Therefore, the present invention proposes an extraction device dedicated to the extraction of oil-soluble vitamins to solve the above problems. Summary of the Invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose an extraction device dedicated to the extraction of oil-soluble vitamins to solve the problems existing in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solution: An extraction device dedicated to the extraction of oil-soluble vitamins, comprising: a pneumatic pressure regulating valve body, and further comprising: an extraction main body group, an activation and elution liquid filling group, an extraction stability, uniform flow, and leak prevention component, and a stable flow extraction speed control component. The activation and elution liquid filling group and the extraction stability, uniform flow, and leak prevention component are arranged on the extraction main body group, and the stable flow extraction speed control component is located below the extraction main body group. The activation and elution liquid filling group is used to provide convenient activation and filling of elution liquid for the extraction work of oil-soluble vitamins. The extraction stability, uniform flow, and leak prevention component is used to reduce the unevenness of the solution flow rate during extraction work and ensure the stability of the overall working performance. The stable flow extraction speed control component is used to control the solution flow rate during extraction work.

[0010] Preferably, the extraction main body group includes an extraction main body cylinder fixedly connected to one end of the pneumatic pressure regulating valve body. A main cover plate is buckled on the extraction main body cylinder. Plugging holes are equidistantly and penetratingly formed on the main cover plate. An extraction column is plugged in the plugging holes, and a filler is placed in the extraction column.

[0011] Preferably, a sample placing disc is rotatably connected to the inner cavity of the extraction main cylinder. The sample placing disc is equidistantly provided with supporting grooves, and sample tubes are placed in the supporting grooves of the sample placing disc.

[0012] Preferably, the activation elution filling group includes an annular groove opened on the buckling main disc cover. A rotating ring is rotatably connected to the annular groove. Symmetrically fixed connections are provided on the rotating ring with liquid storage bins. Plugging covers are plugged on the liquid storage bins. A bendable metal tube is fixedly connected to the bottom end of the liquid storage bin in a communicating manner.

[0013] Preferably, the extraction stability uniform flow leakage prevention component includes positioning rings fixedly connected equidistantly on the buckling main disc cover, and a magnetic ring is arranged inside the positioning rings.

[0014] Preferably, a pushing member is arranged inside the magnetic ring. An annular card slot is opened at the top end of the pushing member. Ridge rings are fixedly connected equidistantly on the upper part of the annular side wall of the magnetic ring.

[0015] Preferably, connecting columns are fixedly connected equidistantly on the outer periphery of the pushing member. Adjusting rings are fixedly connected to the outer ends of the connecting columns. Tightening blocks are slidably connected equidistantly on the magnetic ring.

[0016] Preferably, the steady flow extraction speed regulation component includes a secondary disc rotatably connected to the inner wall of the buckling main disc cover. A sealing annular groove is opened on the secondary disc. Flow holes B are penetrated equidistantly on the sealing annular groove. Transfer cone tubes are fixedly connected equidistantly to the bottom of the secondary disc.

[0017] Preferably, a sealing ring is arranged inside the sealing annular groove. Flow holes A are penetrated equidistantly on the sealing ring.

[0018] Preferably, a support frame is fixedly connected to the bottom of the inner cavity of the extraction main cylinder. A driving member is rotatably connected to the support frame. Arc grooves are opened equidistantly on the driving member. A fitting disc is fixedly connected to the bottom of the secondary disc. Sliding columns are fixedly connected equidistantly on the fitting disc.

[0019] Compared with the prior art, the present invention provides an extraction device dedicated to extracting oil vitamins, having the following beneficial effects: 1. Through the design of the extraction stability uniform flow leakage prevention component, the following benefits can be brought to the overall extraction work: ensuring the uniformity of the flow path and significantly improving the extraction effect and quality. Since this component can ensure that the extraction column is always vertically installed, when the solution flows through the adsorbent filler in the extraction column, the flow path is uniform and stable. On the entire cross-section of the column body, the solution flow rate is consistent, enabling the target substance to fully and evenly contact the adsorbent filler, greatly improving the extraction efficiency and recovery rate. The target components in the sample can be obtained more accurately, providing a more reliable sample for subsequent analysis and detection.

[0020] Protecting the performance of the adsorbent: Vertical installation avoids displacement and re-deposition of the adsorbent filler due to the tilt of the extraction column, maintaining the original tight and uniform structure of the adsorbent; this not only extends the service life of the adsorbent and reduces the cost increase caused by frequent replacement of the adsorbent filler, but also ensures the consistency and stability of the adsorbent performance in each extraction experiment, making the experimental results more repeatable and comparable, and reducing the cost of experimental consumables.

[0021] Eliminate the hidden danger of leakage: The leakage problem caused by non-vertical installation has been fundamentally solved after using this component. This component ensures that the extraction column is installed vertically, so that the connection between the extraction column and the instrument is evenly stressed, and no additional stress is generated due to the tilt of the extraction column, thereby effectively avoiding the deformation and loosening of the sealing ring and eliminating the occurrence of leakage. This not only avoids the waste of samples and reagents, but also prevents corrosion and damage to instruments and equipment due to leakage, thereby extending the service life of the instrument.

[0022] Simplify the operation process and improve the convenience and efficiency of operation: This component has a special positioning ring and magnetic ring adsorption calibration structure. When installing the extraction column, the operator can quickly adjust the extraction column to a vertical state according to the intuitive instructions of the component, which greatly shortens the installation time. Compared with the previous installation method based entirely on experience, the installation efficiency can be improved several times, reducing the waste of experimental preparation time caused by long installation time. Through integrated design, this component optimizes the original complex and error-prone installation steps. Operators no longer need to repeatedly check the verticality of the extraction column. They only need to perform simple operations according to the guidance of the component to complete the installation, which reduces the difficulty of operation and reduces the uncertainty in manual operation.

[0023] 2. When designing the extraction stable uniform flow and leak-proof component of the present invention, the coordinated design of the pushing piece and the fastening block greatly improves the adaptability to extraction columns of different sizes. This design can bring the following benefits: Quick adaptation to different specifications: In actual extraction work, it is often necessary to use a variety of extraction columns of different sizes according to experimental or production requirements. The coordinated design of the pushing piece and the fastening block of the component enables the operator to quickly adjust the component to adapt to extraction columns of different outer diameters and lengths. Whether it is a small laboratory extraction column or an extraction column in large-scale industrial production, it can be adapted and installed through simple operations, which greatly improves the flexibility and efficiency of experimental operations and avoids wasting time waiting for adaptation equipment or performing complex installation adjustments.

[0024] Reducing operation complexity: Traditional extraction column installation components are often designed for specific specifications. When it is necessary to replace extraction columns of different specifications, the entire installation device needs to be replaced or cumbersome modifications are required. However, with the adaptable design of this component, operators do not need to perform complex tool operations or technical adjustments. They can achieve stable installation of different extraction columns simply by adjusting the pusher and fastening block. This reduces the skill requirements for operators. Even those who are new to the equipment can quickly get started and successfully complete the installation of extraction columns of different specifications, reducing the possibility of human operation errors.

[0025] 3. Through the design of the stable-flow extraction speed control component, the present invention can bring the following benefits to the overall extraction work: improving the accuracy and stability of the extraction effect and optimizing the interaction between the target substance and the adsorbent. During the activation and elution stages, this component can accurately control the flow rate of the solution, enabling the target oil vitamin to have sufficient and stable contact time with the adsorbent packing in the extraction column. When the flow rate is stable and appropriate, the target substance can be more fully adsorbed by the adsorbent packing or eluted from the adsorbent packing. For example, during the elution process, the accurate flow rate can ensure that the eluent acts uniformly and continuously on the adsorbent packing adsorbed with the target vitamin, avoiding incomplete elution of the target substance due to too fast a flow rate or long elution time and low efficiency caused by too slow a flow rate, greatly improving the accuracy and stability of the extraction effect.

[0026] Reducing the risk of co-extraction of impurities: Unstable flow rates are likely to elute impurities and target substances simultaneously, affecting the purity of the extract. The stable-flow extraction speed control component can better utilize the differences in the adsorption and elution characteristics of the target substance and impurities on the adsorbent by stabilizing the flow rate. For example, for some impurities with properties similar to the target oil vitamin, under the accurately controlled flow rate, the eluent can preferentially elute the target substance, while the impurities remain on the adsorbent packing, thus effectively improving the purity of the extract, providing a purer sample for subsequent analysis and detection, and helping to obtain more accurate analysis results.

[0027] Enhancing the reliability and repeatability of experimental data: Stable solution flow rate is one of the key factors to ensure consistent experimental conditions. This component provides the same and stable flow rate conditions for each extraction experiment, reducing experimental errors caused by flow rate fluctuations. Whether conducting multiple repeated experiments in the same laboratory or comparative experiments between different laboratories, the stable flow rate can make the experimental results more comparable. Reliable experimental data helps researchers analyze and summarize experimental laws more accurately and promotes the smooth progress of research.

[0028] 4. Through the design of the sealing ring groove, the present invention provides strong support for the coordinated operation of the extraction stable and uniform flow leak-proof component and the stable flow extraction speed regulation component, with the following advantages: strengthening the operation stability of the equipment and ensuring the precise cooperation between components: when the stable flow extraction speed regulation component works, the rotation of the main disk cover and the auxiliary disk needs to be precisely controlled and maintained stably to ensure the precise adjustment of the solution flow rate; the sealing ring groove plays a key limiting role in this process. Through the coordinated cooperation with the extraction column, it effectively prevents the main disk cover and the auxiliary disk from shifting during rotation; this enables the stable operation of the stable flow extraction speed regulation component, ensuring that the solution flow rate always maintains a preset precise value, thereby improving the stability and consistency of extraction and making the results of each extraction experiment or production process more reliable.

[0029] Enhancing the component synergy and promoting the overall efficiency, seamlessly connecting the work process: The dual functions of the sealing ring groove in the two components enable the extraction stable and uniform flow leak-proof component and the stable flow extraction speed regulation component to achieve seamless coordinated work; after the extraction column is installed, the sealing ring groove first plays a sealing role in the extraction stable and uniform flow leak-proof component to ensure the tightness of the entire system; when entering the activation and elution stages and the stable flow extraction speed regulation component starts to work, the sealing ring groove can also assist in the stable rotation of the main disk cover and the auxiliary disk to ensure the accuracy of flow rate regulation; this close coordinated work mode optimizes the entire extraction work process and improves work efficiency; for example, when continuously extracting multiple samples, the equipment can quickly and stably switch from one working stage to another, reducing the intermediate pause and adjustment time and greatly improving the overall extraction efficiency.

[0030] Improving the system integration: The design of the sealing ring groove helps to improve the system integration of the equipment. Through a simple and ingenious structure, multiple important functions are realized, reducing the number and complexity of components in the equipment. This not only reduces the manufacturing cost of the equipment but also makes the maintenance and repair of the equipment more convenient. During equipment maintenance, technicians only need to pay attention to the state of the key component of the sealing ring groove, rather than checking and maintaining multiple complex sealing and limiting structures one by one, improving the repair efficiency, reducing the repair difficulty, and enabling the equipment to return to normal operation faster.

[0031] 5. Through the innovation in the shape and operation mode of the extraction device, the present invention effectively improves the deficiencies of traditional extraction devices and can bring the following benefits: The overall design of the extraction device is cylindrical, with high space utilization efficiency and can adapt to various site layouts. In laboratories or industrial production workshops, space resources are often very precious. The overall cylindrical shape of this extraction device occupies significantly less space compared to the traditional rectangular shape. Its rounded shape has no sharp corners and can be placed more flexibly in a limited space, making full use of irregular spaces in corners and narrow aisles. For example, in a small laboratory, a traditional rectangular extraction device is difficult to be reasonably placed due to its large floor area, which affects the layout of the experimental bench and other equipment. However, the cylindrical extraction device can be easily placed at the edge of the experimental bench or against the wall, without affecting the development of other experimental operations, saving space for the laboratory and making the experimental environment cleaner and more orderly.

[0032] Beneficial for intensive equipment layout: For production scenarios that require large-scale layout of extraction equipment, the cylindrical shape is more conducive to achieving intensive arrangement of equipment. Since the bottom surface of the cylinder is circular, when arranging multiple devices, the gap between devices can be smaller, effectively increasing the number of devices installed per unit area. After adopting the cylindrical extraction device, the number of devices installed in the same area is increased compared to using the rectangular device, improving the utilization rate of the site and providing strong help for enterprises to enhance production capacity without expanding the site scale.

[0033] The operation convenience is significantly improved, and the solution filling process is simplified: The design of the activation elution filling group realizes convenient solution filling and abandons the existing complex operation steps. When filling the solution in traditional extraction devices, multiple valves and pipelines need to be connected, and the operation process is cumbersome and prone to errors. However, through optimized design, the operator of this device can directly and quickly fill the solution into the extraction column, greatly improving work efficiency and reducing the probability of human errors caused by complex operations.

A fitting disc 507 is fixedly connected to the bottom of the sub-disc 501. Sliding columns 508 are fixedly connected to the fitting disc 507 at equal intervals.

[0065] Among them: The extraction stability and uniform flow leakage prevention component 4 is used to reduce the uneven flow rate of the solution in the extraction column 204 during the extraction operation, ensuring the stable adsorption performance of the packing 205 and the condition that no liquid leaks from the bottom end of the extraction column 204.

[0066] The outer surface of the extraction main cylinder 201 is made of a metal material, and the magnet ring 402 in the positioning ring 401 can be adsorbed to it.

[0067] A through vertical guide groove and a sliding groove for assisting the sliding of the adjusting ring 407 are opened on the magnet ring 402.

[0068] The pushing member 403 is used to push the fastening blocks 408, and the convex strip ring 405 can be increased or decreased and improved according to the specific usage situation.

[0069] An auxiliary guiding strip is fixedly connected to the inner wall of the magnet ring 402, and this guiding strip is used for guiding the movement of the fastening block 408.

[0070] The sealing ring groove 409 is mainly used to seal the bottom end of the extraction column 204.

[0071] The steady-flow extraction speed regulation component 5 is used for controlling the flow rate of the solution during the extraction operation.

[0072] An electric control valve group is installed in the flow-through hole B502. During the non-batch extraction process, only the solenoid valve in the hole used for extraction in the electric control valve group is in the open state.

[0073] The flow-through hole B502 coincides with the flow-through hole A411; the sliding column 508 is slidably fitted in the arc groove 506.

[0074] The working principle of all the contents in the above-mentioned embodiments is as follows: In the initial state: The magnet ring 402 is not magnetically attracted to the upper surface of the buckling main disc cover 202, the pushing member 403 does not push the fastening block 408, the annular card slot 404 does not engage with the ribbed ring 405 to fix the position of the pushing member 403, the insertion hole 203 is not in coincidence with the flow-through hole A411 and the flow-through hole B502, and the electric control valve group installed in the flow-through hole B502 is in the closed state.

[0075] The following is the working process of the extraction main body group 2 and the activation elution filling group 3: When in use, first insert the extraction column 204 with the packing 205 into the magnet ring 402, and then the operator only needs to pull the adjusting ring 407 on the magnet ring 402 upward along the sliding groove opened on the magnet ring 402. At this time, the adjusting ring 407 will drive the pushing member 403 to move upward through the connecting column 406. During this process, the vertical guiding groove opened on the magnet ring 402 is used as an auxiliary. Further, during the upward movement of the pushing member 403, the inclined surface of the pushing member 403 will gradually approach and finally push the fastening block 408 slidably connected to the magnet ring 402. During this process, the fastening block 408 will gradually approach the extraction column 204 and squeeze and fix it. Further, during this process, the annular card slot 404 on the pushing member 403 will be engaged with the corresponding ribbed ring 405 to limit the position of the pushing member 403 and realize the pushing and fixing work of the fastening block 408 on the extraction column 204.

[0076] Furthermore, after the extraction column 204 and the magnet ring 402 are indirectly fixed, the magnet ring 402 with the extraction column 204 is placed in the positioning ring 401 on the buckled main disk cover 202. At this time, the bottom end of the extraction column 204 will be inserted through the plug hole 203 opened on the buckled main disk cover 202, and the magnet ring 402 will be magnetically attracted to the upper surface of the buckled main disk cover 202. Under the cooperation with each other, the extraction column 204 is now in a stable and vertically fixed state on the buckled main disk cover 202, and the fixing work is completed.

[0077] Furthermore, according to the extraction needs, it is only necessary to rotate the rotating circle 302 in the annular groove 301 to move the liquid storage tank 303 thereon. It is known that the liquid storage tank 303, the sealing cover 304, and the bendable metal tube 305 are a group, and two groups are arranged on the rotating circle 302, one group is filled with activation liquid, and the other group is filled with eluent; a suction pump is arranged at the bottom end of the bendable metal tube 305, and a switch connected to the pump body is arranged on the liquid storage tank 303. At this time, it is only necessary to turn on the switch and pump in the solvent according to the needs to carry out the extraction operation.

[0078] Please refer to the above working process Figures 1 to 3 , Figure 9 .

[0079] The following is the working process of the extraction stable uniform flow leak-proof component 4 and the steady flow extraction speed control component 5: Furthermore, after the activation or elution solution is added, the flow rate needs to be controlled according to demand. At this time, the driving member 505 on the support frame 504 will rotate under the action of electric control. During the rotation, the bonding disk 507 fixedly connected to the sub-disk 501 will cooperate with the sliding column 508 thereon and the arc groove 506 on the driving member 505 to cause the bonding disk 507 to rotate with the sub-disk 501. At this time, based on the plug-in hole 203 and the flow hole A411 that were originally in a non-overlapping state, the bottom end of the extraction column 204 blocked by the sealing ring 410 will gradually overlap with the flow hole A411 and the flow hole B502, so that the flow rate is controlled according to the degree of overlap.

[0080] Furthermore, the transfer cone 503 at this time serves as a guide for the solution. It should be noted that during the elution process, the transfer cone 503 and the sample tube 207 are placed overlapping, and the sample tube 207 is used to receive the eluted sample solution.

[0081] Please refer to the above working process Figures 2 to 10 .

[0082] Furthermore, the design of the extraction-stabilizing and uniform-flow leak-proof component 4 can bring the following benefits to the overall extraction work: ensuring the uniformity of the flow path, significantly improving the extraction effect and quality; since this component can ensure that the extraction column 204 is always vertically installed, when the solution flows through the adsorbent filler in the extraction column 204, the flow path is uniform and stable; across the entire cross-section of the column, the solution flow rate is consistent, enabling the target substance and the adsorbent filler 205 to come into full and uniform contact, greatly improving the extraction efficiency and recovery rate; and being able to more accurately obtain the target components in the sample, providing a more reliable sample for subsequent analysis and detection.

[0083] Protecting the adsorbent performance: The vertical installation avoids the displacement and re-packing of the adsorbent filler 205 due to the inclination of the extraction column 204, maintaining the originally tight and uniform structure of the adsorbent; this not only extends the service life of the adsorbent, reduces the cost increase caused by frequent replacement of the adsorbent filler 205, but also ensures the consistency and stability of the adsorbent performance in each extraction experiment, making the experimental results have better repeatability and comparability, and reducing the cost of experimental consumables.

[0084] Eliminating the hidden danger of liquid leakage: The problem of liquid leakage caused by non-vertical installation is fundamentally solved after using this component. This component ensures the vertical installation of the extraction column 204, making the force on the connection part between the extraction column 204 and the instrument uniform, and not generating additional stress due to the inclination of the extraction column 204, thereby effectively avoiding the deformation and loosening of the sealing ring 410 and preventing the occurrence of liquid leakage; this not only avoids the waste of samples and reagents, but also prevents the corrosion and damage of the instrument and equipment caused by liquid leakage, and extends the service life of the instrument.

[0085] Simplifying the operation process and enhancing the operation convenience and efficiency: This component has a special positioning ring 401 and a magnet ring 402 adsorption calibration structure. When the operator installs the extraction column 204, they can quickly adjust and install the extraction column 204 to the vertical state according to the intuitive indication of the component, greatly shortening the installation time; compared with the previous installation method relying entirely on experience, the installation efficiency can be increased several times, reducing the waste of experimental preparation time caused by overly long installation time, and through the integrated design, this component optimizes the originally complex and error-prone installation steps. The operator no longer needs to repeatedly check the verticality of the extraction column 204, and can complete the installation by simply following the guidance of the component, reducing the operation difficulty and the uncertainty in manual operation.

[0086] Furthermore, when designing the extraction stable uniform flow leak-proof component 4, the cooperative design of the pusher 403 and the fastening block 408 greatly improves the adaptability to extraction columns 204 of different sizes. This design brings the following benefits: Quick adaptation to different specifications; In actual extraction work, it is often necessary to use extraction columns 204 of various different sizes according to experimental or production requirements. The cooperative design of the pusher 403 and the fastening block 408 of this component enables operators to quickly adjust the component to adapt to extraction columns 204 with different outer diameters and lengths. Whether it is a small laboratory extraction column 204 or an extraction column 204 in large-scale industrial production, the adaptation and installation can be completed through simple operations, greatly improving the flexibility and efficiency of experimental operations, and avoiding wasting time due to waiting for adapted equipment or performing complex installation adjustments.

[0087] Reduce operation complexity: Traditional extraction column 204 installation components are often designed for specific specifications. When it is necessary to replace extraction columns 204 of different specifications, the entire installation device needs to be replaced or cumbersome modifications are required; However, the adaptation design of this component enables operators to achieve stable installation of different extraction columns 204 without complex tool operations or technical adjustments. Just by simply adjusting the pusher 403 and the fastening block 408, this reduces the skill requirements for operators. Even personnel who are new to this equipment can quickly get started and successfully complete the installation work of extraction columns 204 of different specifications, reducing the possibility of human operation errors.

[0088] Furthermore, through the design of the stable flow extraction speed control component 5, the following benefits can be brought to the overall extraction work: Improve the accuracy and stability of the extraction effect, and optimize the interaction between the target substance and the adsorbent; In the activation and elution stages, this component can accurately control the flow rate of the solution, enabling the target oil vitamin to have sufficient and stable contact time with the adsorbent packing 205 in the extraction column 204; When the flow rate is stable and appropriate, the target substance can be more fully adsorbed by the adsorbent packing 205 or eluted from the adsorbent packing 205; For example, during the elution process, the accurate flow rate can ensure that the eluent acts uniformly and continuously on the adsorbent packing 205 adsorbed with the target vitamin, avoiding incomplete elution of the target substance due to too fast a flow rate or too long an elution time and low efficiency due to too slow a flow rate, greatly improving the accuracy and stability of the extraction effect.

[0089] Reduce the risk of co-extraction of impurities: Unstable flow rate easily elutes impurities and target substances simultaneously, affecting the purity of the extract; the steady-flow extraction speed control component 5 can better utilize the differences in the adsorption and elution characteristics of the target substance and impurities on the adsorbent by stabilizing the flow rate; for example, for some impurities with similar properties to the target oil vitamin, under precisely controlled flow rate, the eluent can preferentially elute the target substance, while the impurities remain on the adsorbent packing 205, thus effectively improving the purity of the extract, providing a purer sample for subsequent analysis and detection, and helping to obtain more accurate analysis results.

[0090] Enhance the reliability and repeatability of experimental data: Stable solution flow rate is one of the key factors to ensure consistent experimental conditions; this component provides the same and stable flow rate conditions for each extraction experiment, reducing experimental errors caused by flow rate fluctuations; whether conducting multiple repeated experiments in the same laboratory or comparative experiments between different laboratories, stable flow rate can make the experimental results more comparable, and reliable experimental data helps researchers analyze and summarize experimental laws more accurately, promoting the smooth progress of research.

[0091] Furthermore, the design of the sealing ring groove 409 provides strong support for the collaborative work of the extraction stable and uniform flow leakage prevention component 4 and the steady-flow extraction speed control component 5, with the following benefits: strengthen the stability of equipment operation and ensure precise cooperation between components; when the steady-flow extraction speed control component 5 works, the rotation of the main disk cover 202 and the auxiliary disk 501 needs to be precisely controlled and kept stable to ensure the precise adjustment of the solution flow rate; the sealing ring groove 409 plays a key limiting role in this process, and through the collaborative cooperation with the extraction column 204, effectively prevents the main disk cover 202 and the auxiliary disk 501 from shifting during rotation; this enables the steady-flow extraction speed control component 5 to operate stably, ensuring that the solution flow rate always maintains at the preset precise value, thereby improving the stability and consistency of extraction, and making the results of each extraction experiment or production process more reliable.

[0092] Improve component synergy, promote the overall effectiveness, and seamlessly connect the work process: The dual functions of the sealing ring groove 409 in the two components enable the extraction stable and uniform flow anti-leakage component 4 and the stable flow extraction speed regulation component 5 to achieve seamless collaborative work; after the extraction column 204 is installed, the sealing ring groove 409 first plays a sealing role in the extraction stable and uniform flow anti-leakage component 4 to ensure the tightness of the entire system; when entering the activation and elution stages and the stable flow extraction speed regulation component 5 starts to work, the sealing ring groove 409 can also assist in the stable rotation of the main disc cover 202 and the auxiliary disc 501 to ensure the accuracy of flow rate regulation; this close collaborative work mode optimizes the entire extraction work process and improves work efficiency; for example, when continuously extracting multiple samples, the device can quickly and stably switch from one working stage to another, reducing the intermediate pause and adjustment time and greatly improving the overall extraction efficiency.

[0093] Improve the system integration: The design of the sealing ring groove 409 helps to improve the system integration of the device. Through a simple and ingenious structure, multiple important functions are realized, reducing the number and complexity of components in the device. This not only reduces the manufacturing cost of the device but also makes the maintenance and servicing of the device more convenient. During device repair, technicians only need to pay attention to the status of the key component, the sealing ring groove 409, instead of checking and maintaining multiple complex sealing and limiting structures one by one, improving the repair efficiency, reducing the repair difficulty, and enabling the device to resume normal operation faster.

[0094] Furthermore, through the innovation in the shape and operation mode of the extraction device, the deficiencies of traditional extraction devices are effectively improved, bringing the following benefits: The overall cylindrical design of the extraction device enables efficient space utilization and can adapt to various site layouts; in laboratory or industrial production workshop sites, space resources are often very precious; the overall cylindrical shape of this extraction device occupies significantly less space compared to the traditional cuboid shape, and its rounded shape has no sharp corners, enabling it to be placed more flexibly in a limited space and making full use of irregular spaces in corners and narrow aisles; for example, in a small laboratory, a traditional cuboid extraction device is difficult to be reasonably placed due to its large floor area, affecting the layout of the experimental bench and other equipment, while the cylindrical extraction device can be easily placed at the edge of the experimental bench or against the wall without affecting the conduct of other experimental operations, saving space for the laboratory and making the experimental environment cleaner and more orderly.

[0095] Beneficial for intensive equipment layout: For production scenarios that require large-scale layout of extraction equipment, the cylindrical shape is more conducive to achieving intensive arrangement of equipment. Since the bottom surface of the cylinder is circular, when arranging multiple pieces of equipment, the gap between the equipment can be smaller, which can effectively increase the number of equipment installed per unit area. After adopting the cylindrical extraction device, the number of equipment installed in the same area has increased compared to using a cuboid device, improving the utilization rate of the site and providing strong assistance for enterprises to enhance production capacity without expanding the site scale.

[0096] The operational convenience is significantly improved, and the solution filling process is simplified: The design of the activation elution filling group 3 realizes convenient solution filling and abandons the existing complex operation steps. When the traditional extraction device fills the solution, it needs to be connected through multiple valves and pipelines, and the operation process is cumbersome and prone to errors. However, through optimized design, this device enables operators to directly and quickly fill the solution into the extraction column 204, greatly improving work efficiency and reducing the probability of human errors caused by complex operations.
