Description

Technical Field

[0001] This invention relates to the field of extraction and separation technology, specifically to a multiphase layered controllable plant polysaccharide extraction and separation device. Background Technology

[0002] Plant polysaccharides, as an important class of natural bioactive substances, are widely found in the roots, stems, leaves, fruits and seeds of various plants. They have a variety of physiological functions such as immune regulation, anti-oxidation, hypoglycemia and anti-tumor. They are now widely used in food, health products, medicine, cosmetics and other fields. The market demand for high-purity plant polysaccharides is increasing day by day.

[0003] Extraction and separation of plant polysaccharides is the core link to realize their industrial application. Among them, extraction and multiphase separation are key processes: first, the polysaccharides in the plant raw materials are dissolved to form a mixture through solvent extraction, and then the density and interfacial tension differences between the polysaccharide phase and the phases such as oil, protein, and solid impurities are used to achieve separation, and finally a high-purity polysaccharide extract is obtained. However, existing equipment has obvious defects: relying on natural gravity for stratification results in low efficiency and a thick transition layer in viscous mixtures; large errors in manual observation of phase interfaces lead to easy phase miscibility and insufficient purity; it lacks precise stratification assistance and development structures, and has poor equipment adaptability and low automation, making it difficult to meet the needs of efficient and precise industrial production. Therefore, it is necessary to propose a multiphase stratification controllable plant polysaccharide extraction and separation equipment. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a multiphase layered controllable plant polysaccharide extraction and separation device.

[0005] The technical solution adopted by this invention to solve its technical problem is: a multiphase layered controllable plant polysaccharide extraction and separation device, including a tank. Transparent observation windows are embedded in the outer walls of both sides of the tank. A controller is installed on the outer wall of the tank near the transparent observation windows. Multiple feed pipes are embedded in the top of the tank, and a liquid outlet pipe is embedded in the bottom of the tank. A servo motor is installed in the top of the tank, and a transmission rod is fixedly connected to the output end of the servo motor. Multiple sets of stirring rods are installed on the wall of the transmission rod. Multiple sliding frames are slidably fitted onto the outer wall of the tank. An electromagnetic actuator is installed at the bottom of one end of the upper sliding frame, and an electromagnetic coil is fixedly connected to the output end of the electromagnetic actuator. A support frame is installed at the upper end of the outer wall of the tank, and a cylinder is fixedly connected to the bottom end of the support frame. The output end of the cylinder is connected to the upper sliding frame. Foldable diamond-shaped hinges are installed between adjacent ends of the multiple sliding frames. A through hole is opened at one end of each of the three lower sliding frames. A rotating block is provided at the bottom of the sliding frame. Multiple miniature sheet lasers are embedded in the arc-shaped end of the rotating block. A cylinder is hinged between the rotating block and the sliding frame.

[0006] Specifically, the bottom of the tank is fixedly connected with multiple support feet, and two liquid distribution pipes are embedded in the lower end of the outer wall of the tank.

[0007] Specifically, a limiting groove is formed on the outer wall of the tank, and a limiting block connected to the sliding frame is slidably engaged on the inner wall of the limiting groove.

[0008] Specifically, heating wires are embedded in the side wall of the tank near the two sides of the transparent observation window.

[0009] Specifically, the electromagnetic coils are distributed in multiple strands within the inner frame of the sliding frame, and there is a gap between the electromagnetic coils and the outer wall of the tank. The electromagnetic coils at the inner ends of the multiple sliding frames are electrically connected by elastic connecting wires, and the electromagnetic coils on the multiple sliding frames are distributed in a trapezoidal shape.

[0010] Specifically, the diameter of the through hole is larger than the outer diameter of the electromagnetic driver.

[0011] Specifically, multiple micro-plate lasers of varying lengths are distributed along the arc-shaped segment of the rotating block, and each micro-plate laser corresponds to a transparent observation window.

[0012] One of the beneficial effects of this invention is that this device uses a cylinder to drive multiple sets of sliding frames to lift and lower in a coordinated manner. Combined with the guiding and limiting functions of the limiting blocks and grooves, it can precisely move the electromagnetic coils to the desired stratification area. The gradient magnetic field formed by the multiple electromagnetic coils can apply a directional thrust to the magnetically responsive impurity phase, breaking the interfacial tension constraint of the viscous mixture, efficiently accelerating multiphase stratification, and solving the problems of time-consuming and inefficient traditional natural gravity stratification.

[0013] The second beneficial effect of this invention is that by utilizing miniature sheet lasers of different lengths, it achieves full-area, blind-spot-free irradiation at the same horizontal level for each layer. The laser surface penetrates the central axis of the tank and refracts to a transparent observation window at the other end, forming clear multi-channel reflections by utilizing the difference in refractive index between the oil and water phases. Operators can intuitively and accurately identify the position and flatness of the phase interface, completely solving the pain points of blurry and large positioning errors in traditional manual observation.

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-6 As shown, the present invention provides the following technical solution: Example 1: A multiphase layered controllable plant polysaccharide extraction and separation device includes a tank 1. Transparent observation windows 10 are embedded in the outer walls of both sides of the tank 1. A controller 12 is installed on the outer wall of the tank 1 near the transparent observation windows 10. Multiple feed pipes 11 are embedded in the top of the tank 1. A liquid outlet pipe 13 is embedded in the bottom of the tank 1. A servo motor 2 is installed in the top of the tank 1. A transmission rod 21 is fixedly connected to the output end of the servo motor 2. Multiple sets of stirring rods 22 are installed on the rod wall of the transmission rod 21. Multiple support feet 14 are fixedly connected to the bottom of the tank 1. Two liquid distribution pipes 15 are embedded in the lower end of the outer wall of the tank 1. Heating wires 110 are embedded in the side wall of the tank 1 near the transparent observation windows 10.

[0019] The controller 12 is electrically connected to the servo motor 2 and the heating wire 110, and can precisely control the stirring speed and stirring time of the servo motor 2 and the heating temperature of the heating wire 110. Multiple sets of stirring rods 22 are distributed at equal intervals along the wall of the transmission rod 21, and the end of the stirring rod 22 away from the transmission rod 21 is left with a gap from the inner wall of the tank 1 to avoid scraping the tank 1 during the stirring process; Two separator pipes 15 are positioned at different heights on the lower end of the outer wall of the tank 1. They can be selectively opened according to the stratification requirements to achieve separate collection of different phase systems.

[0020] In operation, pretreated plant polysaccharide raw materials and extraction solvent are first fed into tank 1 through feed pipe 11. The heating temperature of heating wire 110 is set by controller 12, and heating wire 110 maintains a constant temperature for the material inside tank 1, improving polysaccharide dissolution efficiency. Simultaneously, servo motor 2 is started, driving transmission rod 21 and multiple sets of stirring rods 22 to rotate, thoroughly mixing the raw materials and solvent to achieve extraction and dissolution of plant polysaccharides. The stirring time is precisely controlled by controller 12. After extraction, servo motor 2 and heating wire 110 are turned off, and the mixture inside tank 1 is allowed to stand. Natural gravity stratification is achieved by utilizing the density differences of each phase system. The operator can observe the internal stratification status in real time through transparent observation window 10. After stratification is completed, according to the phase distribution position, the low-level and high-level separatory pipes 15 are opened in sequence to discharge the impurity phase and polysaccharide phase respectively. The remaining residual liquid can be completely discharged through bottom outlet pipe 13, completing one extraction and separation operation.

[0021] Example 2: The technical solution of this example, which differs from Example 1, includes: multiple sliding frames 3 are slidably fitted onto the outer wall of the tank 1; an electromagnetic actuator 31 is installed at the bottom of one end of the upper sliding frame 3; an electromagnetic coil 32 is fixedly connected to the output end of the electromagnetic actuator 31; a support frame is installed at the upper end of the outer wall of the tank 1; a cylinder 24 is fixedly connected to the bottom end of the support frame, and the output end of the cylinder 24 is connected to the upper sliding frame 3; foldable diamond-shaped hinges 311 are installed between adjacent ends of the multiple sliding frames 3; and three sliding frames at the lower end... One end of each frame 3 has a through hole 301. The outer wall of the tank 1 has a limiting groove 101. The inner wall of the limiting groove 101 is slidably engaged with a limiting block 310 connected to the sliding frame 3. The electromagnetic coils 32 are distributed in multiple strands in the inner frame of the sliding frame 3, and there is a gap between the electromagnetic coils 32 and the outer wall of the tank 1. The electromagnetic coils 32 at the inner ends of the multiple sliding frames 3 are electrically connected by elastic connecting wires 33, and the electromagnetic coils 32 on the multiple sliding frames 3 are distributed in a trapezoidal shape. The diameter of the through hole 301 is larger than the outer diameter of the electromagnetic actuator 31.

[0022] The controller 12 is electrically connected to the cylinder 24 and the electromagnetic driver 31, and can adjust the extension and retraction stroke of the cylinder 24 and the output power of the electromagnetic driver 31. The limiting block 310 is adapted to the limiting groove 101, which guides and limits the up and down sliding of the sliding frame 3 and prevents the sliding frame 3 from deviating; the foldable diamond hinge 311 realizes the linkage lifting and lowering of multiple sliding frames 3, ensuring the synchronous lifting and lowering of each sliding frame 3. The elastic connecting wire 33 has tensile elasticity, adapts to the lifting and lowering action of the sliding frame 3, and ensures the continuity of electrical connection of each electromagnetic coil 32. The electromagnetic coil 32 forms a ring-shaped magnetic field region on the outer wall of the tank 1, and leaves a gap between it and the outer wall of the tank 1 to avoid interference from the metal material of the tank 1 in the transmission of the magnetic field, and at the same time to prevent the electromagnetic coil 32 from scratching the tank 1 when the sliding frame 3 is raised and lowered.

[0023] In use, after the extraction and stirring in Example 1 are completed, the controller 12 starts the cylinder 24. The cylinder 24 drives the upper sliding frame 3 to slide down along the outer wall of the tank 1. Under the linkage of the foldable diamond hinge 311, multiple sliding frames 3 move down synchronously. The limit block 310 slides along the limit groove 101 to ensure that the sliding frame 3 rises and falls smoothly until the electromagnetic coil 32 moves to the expected stratification area of ​​the mixture inside the tank 1. Then the cylinder 24 is closed to complete the positioning. Then, the electromagnetic actuator 31 is activated, supplying power to each electromagnetic coil 32. The multiple electromagnetic coils 32 generate a gradient magnetic field, applying a directional electromagnetic thrust to the magnetically responsive impurity phases in the mixture. This breaks the interfacial tension binding of the viscous mixture, accelerating the separation of the phases and replacing traditional gravity-based separation, significantly improving separation efficiency (the magnetic pull is greater than the viscous resistance of the viscous liquid to the impurity particles, thus forcing the impurity particles to overcome the viscous resistance and migrate downwards in a directional manner, while simultaneously breaking the viscous adhesion between phases caused by interfacial tension, allowing the previously difficult-to-separate polysaccharide, oil, and impurity phases to quickly detach and clearly separate). During the separation process, the operator can observe the separation progress through the transparent observation window 10. If the area of ​​magnetic field action needs adjustment, the height of the sliding frame 3 can be finely adjusted using cylinder 24. After separation is complete, the electromagnetic actuator 31 is turned off, and the separator 15 and outlet 13 are opened as in Example 1 to complete phase collection. After collection, the sliding frame 3 is reset to the upper end of the tank body 1 by cylinder 24.

[0024] Example 3: The technical solution of this example that differs from that of Example 1 includes: a rotating block 4 is provided at the bottom of the sliding frame 3, and multiple miniature sheet lasers 41 are embedded in the arc-shaped end of the rotating block 4. A cylinder 42 is hinged between the rotating block 4 and the sliding frame 3. The multiple miniature sheet lasers 41 are distributed in different lengths in the arc-shaped section of the rotating block 4, and each miniature sheet laser 41 corresponds to the transparent observation window 10.

[0025] The controller 12 is electrically connected to the cylinder 42 and the miniature sheet laser 41, and can adjust the extension angle of the cylinder 42 and the opening, closing and power adjustment of the miniature sheet laser 41.

[0026] In use, the controller 12 starts the cylinder 42, which extends and retracts to drive the rotating block 4 to rotate around the hinge point, adjusting the irradiation angle of the miniature sheet laser 41 so that the sheet laser surfaces emitted by each miniature sheet laser 41 point at an angle of 30°-45° towards the inside of the tank 1, and all sheet laser surfaces accurately cover different layer heights inside the tank 1, so as to fully irradiate different areas of the layer height. After angle adjustment, cylinder 42 is shut off to complete positioning. Then, the miniature sheet laser 41 is activated. Multiple miniature sheet lasers 41 of different lengths operate synchronously, emitting sheet laser surfaces that are evenly distributed at the same layer height, covering the central, edge, and corner areas of the tank 1 at that height. This achieves comprehensive illumination of different areas at the same layer height, completely eliminating blind spots. The laser surface passes through the transparent observation window 10 and irradiates the mixture. Utilizing the refractive index difference between the oil and water phases (polysaccharide phase), multiple clear, continuous, and unbiased annular optical reflection lines are formed at the phase interface at the same layer height. Operators can intuitively and accurately identify the overall outline, flatness, and layering status of the phase interface at that layer height through the transparent observation windows 10 on both sides of the tank 1, solving the problems of blurred phase interface, large positioning errors, and blind spots in traditional manual observation.
