Description

Technical Field

[0001] This invention relates to the field of polysaccharide extraction technology, specifically to a high-efficiency Chrysanthemum polysaccharide extraction device. Background Technology

[0002] Chrysanthemum polysaccharides exert bioactive effects in anti-tumor, anti-inflammatory, antiviral, hypoglycemic, anti-aging, and immune-boosting processes. The extraction of Chrysanthemum polysaccharides typically involves the following steps: Chrysanthemum powder → hot water extraction (enzyme extraction) → solid-liquid separation → ethanol precipitation → washing and drying → polysaccharide precipitation.

[0003] After extraction, the polysaccharide extract from Chuzhou chrysanthemum can be separated from the residue using a filter plate. During solid-liquid separation, the residue is retained and accumulates on the filter plate, but some of the polysaccharide extract remains within it. Current extraction equipment struggles to effectively separate this portion of the polysaccharide extract from the residue. Therefore, we propose a highly efficient Chuzhou chrysanthemum polysaccharide extraction device. Summary of the Invention

[0004] (i) In view of the shortcomings of the prior art, the present invention provides a high-efficiency Chrysanthemum polysaccharide extraction device, which overcomes the problem that the existing plant polysaccharide extraction device is difficult to fully squeeze the residue. By controlling the filter press mechanism, the extract stored in the residue can be squeezed out and flow into the alcohol precipitation tank, reducing the waste of extract and increasing the yield of Chrysanthemum polysaccharide.

[0005] (II) To achieve the above objectives, the present invention is implemented through the following technical solution: a high-efficiency Chrysanthemum polysaccharide extraction device, comprising an extraction tank and an alcohol precipitation tank, wherein the extraction tank is provided with an upper side door, the alcohol precipitation tank is provided with a lower side door, a feed pipe is connected between the extraction tank and the alcohol precipitation tank, an electric valve is installed on the feed pipe, a feeding mechanism is connected to the extraction tank, and an electric heating ring and a filter plate are installed inside the extraction tank, a pressure filtration mechanism is provided on the extraction tank, and an alcohol injection mechanism is connected to the alcohol precipitation tank;

[0006] The filter press mechanism includes a sleeve rod and a support shaft rotatably mounted on the extraction tank. A limit rod is fixed on the support shaft. The sleeve rod has a slide rail that cooperates with the support shaft and a limit port that cooperates with the limit rod. A spring is installed between the slide rail and the support shaft. An air bladder is installed on the sleeve rod, and two sets of filter press cylinders are rotatably mounted on the bottom of the sleeve rod. A motor for driving the support shaft is installed on the extraction tank.

[0007] Preferably, the filter press mechanism is equipped with a centralized cleaning mechanism for collecting residue remaining on the filter plate; the centralized cleaning mechanism includes an electric push rod installed at the bottom of the sleeve rod, a connecting rod fixed to the movable end of the electric push rod, a collecting plate inserted into the connecting rod, two sets of receiving plates symmetrically fixed on the collecting plate, and a locking part provided between the connecting rod and the collecting plate. The locking part includes an upper locking channel on the connecting rod and a lower locking channel on the collecting plate, a locking piece slidably installed on the lower locking channel, a guide rod fixed on the locking piece, a rotating shaft rotatably installed on the collecting plate, a pull ring fixed on the rotating shaft, and a torsion spring sleeved on the rotating shaft, the torsion spring being fixed between the pull ring and the collecting plate, and a guide channel for cooperating with the guide rod being opened on the pull ring.

[0008] Preferably, the alcohol precipitation tank is equipped with a scraping mechanism, which includes a settling plate fixed inside the alcohol precipitation tank, a leakage hole formed on the settling plate, a scraping part for removing polysaccharide precipitate from the settling plate, and a sealing part for sealing the leakage hole. The scraping part includes a fine-hole scraper, a screw rotatably installed inside the alcohol precipitation tank, and a guide post fixed inside the alcohol precipitation tank. Two sets of connecting rods are fixed on the fine-hole scraper, which respectively cooperate with the screw and the guide post. A second motor for driving the screw is installed on the alcohol precipitation tank. The sealing part includes a hydraulic rod installed at the bottom of the alcohol precipitation tank, and a sealing plate that cooperates with the leakage hole is fixed on the movable end of the hydraulic rod.

[0009] Preferably, the extraction tank is equipped with a clearing mechanism, which includes a cross-shaped nozzle installed inside the extraction tank. One end of the cross-shaped nozzle extends out of the extraction tank and is equipped with a one-way valve. The extended end of the cross-shaped nozzle is connected to an air duct, and the other end of the air duct is connected to a blower. The cross-shaped nozzle is located below the filter plate, and the air nozzle of the cross-shaped nozzle faces downward.

[0010] Preferably, the injection mechanism is provided in two sets, each set of the injection mechanism includes an injection pipe connected to the extraction tank, the other end of the injection pipe is connected to a storage tank, and a material pump is installed on the injection pipe.

[0011] Preferably, the alcohol injection mechanism includes an alcohol injection pipe connected to an alcohol precipitation tank, the other end of the alcohol injection pipe connected to an alcohol storage tank, and a liquid pump installed on the alcohol injection pipe.

[0012] Preferably, a drain pipe is installed in the alcohol settling tank below the settling plate.

[0013] (III) This invention provides a high-efficiency Chrysanthemum polysaccharide extraction device, which has the following beneficial effects:

[0014] 1. By adding an extraction tank, filter plates, and a filtration mechanism, when the liquid level in the extraction tank drops, the filtration mechanism can be controlled to work, squeezing the residue trapped on the filter plates. This allows the extract stored in the residue to be squeezed out and flow into the alcohol precipitation tank, reducing the waste of extract and increasing the yield of polysaccharides. After the polysaccharide extract has fully entered the alcohol precipitation tank, the alcohol injection mechanism can be controlled to inject ethanol into it, which will generate polysaccharide precipitate, realizing the integration of extraction and alcohol precipitation, and improving the production efficiency of Chuzhou chrysanthemum polysaccharides.

[0015] 2. By adding a filter press mechanism, when the liquid level in the extraction tank drops, the air bladder will also drop, and the filter press cylinder will press against the filter plate again. As the filter press cylinder rotates, the residue can be fully squeezed, and the extract stored in the residue will be squeezed out and flow into the alcohol precipitation tank, reducing the waste of extract and increasing the yield of polysaccharides.

[0016] 3. By adding a centralized cleaning mechanism, the electric push rod is activated, which drives the collecting plate to move down and contact the filter plate. As the collecting plate rotates, the material residue on the filter plate can be scraped onto one side of the collecting plate. The upper door is opened, and the collecting plate is pulled outward, which drives the receiving plate to move outward, so that the material residue can be discharged from the extraction tank. Removing the material residue is relatively simple and convenient.

[0017] 4. By adding a locking part, the stability of the connection between the connecting rod and the collecting plate is improved. When the pull ring is lifted upward, the locking piece moves downward and disengages from the upper locking channel, and the operator can pull the collecting plate outward. The operation is simple and convenient.

[0018] 5. By adding a scraping mechanism and starting motor two, the fine-hole scraper moves and gathers the polysaccharide precipitate generated on the top of the settling plate to one side of the filter plate. Then, the hydraulic rod is activated, and the sealing plate is disengaged from the leakage hole, which can separate the ethanol solution and polysaccharide precipitate, realizing automated separation, which is simple and convenient.

[0019] 6. By adding a clearing mechanism and starting the blower, air is sprayed out from the cross nozzle to carry out the material blocked in the filter plate channels, thereby clearing the filter plate and preventing severe blockage that would affect the permeation of the polysaccharide extract.

[0020] In summary, this invention integrates extraction and alcohol precipitation, improving production efficiency. Furthermore, the pressure filtration process reduces waste of extract and increases polysaccharide yield, while also making the overall operation more convenient. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Example 1

[0037] like Figures 1-12 As shown, a high-efficiency Chrysanthemum polysaccharide extraction device includes an extraction tank 1 and an alcohol precipitation tank 3. The extraction tank 1 is provided with an upper side door 1a for removing the residue trapped on the filter plate 12. The alcohol precipitation tank 3 is provided with a lower side door 3a for removing the polysaccharide precipitate. A feed pipe 2 is installed between the extraction tank 1 and the alcohol precipitation tank 3, and a plate frame is fixed between the extraction tank 1 and the alcohol precipitation tank 3 to improve the stability of the connection between the extraction tank 1 and the alcohol precipitation tank 3. An electric valve 4 is installed on the feed pipe 2. A feeding mechanism 9 is installed on the extraction tank 1, and an electric heating ring 11 and a filter plate 12 are installed inside the extraction tank 1. A filter press mechanism 5 is provided on the extraction tank 1, and an alcohol injection mechanism 10 is installed on the alcohol precipitation tank 3. The feeding mechanism 9 injects raw materials (including enzyme solution, water, and Chuzhou chrysanthemum powder) into the extraction tank 1. The electric heating ring 11 is activated to heat the material to a suitable temperature, and then the polysaccharide extraction begins. After extraction, the electric valve 4 is activated, and the residue is trapped on the filter plate 12. The extract passes through the filter plate 12 and enters the alcohol precipitation tank 3 through the feed pipe 2. As the liquid level in the extraction tank 1 drops, the pressure filter mechanism 5 can be controlled to work, squeezing the residue trapped on the filter plate 12. This squeezes out the extract stored in the residue and allows it to flow into the alcohol precipitation tank 3, reducing the waste of extract and increasing the yield of polysaccharides. When the polysaccharide extract has fully entered the alcohol precipitation tank 3, the alcohol injection mechanism 10 is controlled to inject ethanol into it, which generates polysaccharide precipitate, realizing the integration of extraction and alcohol precipitation, and improving production efficiency.

[0038] The filter press mechanism 5 includes a sleeve rod 54 and a support shaft 51 rotatably mounted on the extraction tank 1. A limit rod 53 is fixed on the support shaft 51. Multiple sets of limit rods 53 can be provided. The sleeve rod 54 is provided with a slide 55 that cooperates with the support shaft 51 and a limit port 56 that cooperates with the limit rod 53. A spring 57 is installed between the slide 55 and the support shaft 51. An air bag 59 is installed on the sleeve rod 54, and two sets of filter press cylinders 58 are rotatably mounted on the bottom of the sleeve rod 54. A motor 52 for driving the support shaft 51 is installed on the extraction tank 1. In this process, after the raw material is injected into the extraction tank 1, the liquid level in the extraction tank 1 gradually rises, and the air bag 59 also floats up (the spring 57 is squeezed), which drives the sleeve rod 54 to move upward, and then drives the filter cylinder 58 to move upward and separate from the filter plate 12. The motor 52 is started, which drives the support shaft 51 to rotate, thereby driving the sleeve rod 54 to rotate, which in turn drives the filter cylinder 58 to rotate. This can stir the raw material in the extraction tank 1, which is conducive to the full dissolution of polysaccharides. Moreover, during the entire extraction process, the filter cylinder 58 moves upward and separates from the filter plate 12. On the one hand, this can avoid wear caused by the rapid rotation between the filter cylinder 58 and the filter plate 12 during the extraction period, thus ensuring the service life of the filter plate 12. On the other hand, it can prevent the filter cylinder 58 from directly pressing the incompletely dissolved Chuji powder into the filter holes of the filter plate 12 during the extraction period, causing blockage and affecting the subsequent permeation of the polysaccharide extract through the filter plate 12.

[0039] After extraction, open the electric valve 4, and the polysaccharide extract enters the alcohol precipitation tank 3. The residue is retained on the filter plate 12. When the liquid level in the extraction tank 1 drops, the air bag 59 will also drop. Under the action of gravity and the elastic force of the spring 57, the filter cylinder 58 will press against the filter plate 12 again. Start the motor 52 to drive the filter cylinder 58 to rotate, which can fully squeeze the residue, squeeze out the extract stored in the residue and flow into the alcohol precipitation tank 3, reduce the waste of extract and increase the yield of polysaccharides.

[0040] In this embodiment, the feeding mechanism 9 is provided in two sets. Each set of feeding mechanism 9 includes a feeding pipe 92 connected to the extraction tank 1. The other end of the feeding pipe 92 is connected to a storage tank 91, and a feed pump 93 is installed on the feeding pipe 92. One set of feeding mechanism 9 injects enzymatic hydrolysate into the extraction tank 1, and the other set of feeding mechanism 9 injects a mixture of water and Chuzhou chrysanthemum powder into the extraction tank 1. When the feed pump 93 is started, the corresponding raw materials will enter the extraction tank 1 along the feeding pipe 92.

[0041] In this embodiment, the alcohol injection mechanism 10 includes an alcohol injection pipe 103 connected to an alcohol precipitation tank 3. The other end of the alcohol injection pipe 103 is connected to an alcohol storage tank 101, and a liquid pump 102 is installed on the alcohol injection pipe 103. After the polysaccharide extract enters the alcohol precipitation tank 3, the liquid pump 102 is activated, and the ethanol in the alcohol storage tank 101 enters the alcohol precipitation tank 3 along the alcohol injection pipe 103. The ethanol contacts the polysaccharide extract, generating a polysaccharide precipitate.

[0042] Example 2

[0043] refer to Figure 6 , Figures 8-9 Similar to Embodiment 1, but with an improvement, the filter press mechanism 5 is equipped with a centralized cleaning mechanism 6 for collecting the residue remaining on the filter plate 12. The centralized cleaning mechanism 6 includes an electric push rod 61 installed at the bottom of the sleeve rod 54. A connecting rod 62 is fixed to the movable end of the electric push rod 61. A collecting plate 63 is inserted into the connecting rod 62. Two sets of receiving plates 64 are symmetrically fixed on the collecting plate 63. A locking part 65 is provided between the connecting rod 62 and the collecting plate 63 to ensure the stability of the connection between the connecting rod 62 and the collecting plate 63. After the filter press is completed, the electric push rod 61 is activated, which drives the connecting rod 62 to move down, and then drives the collecting plate 63 to move down and abut against the filter plate 12. As the collecting plate 63 rotates, the slag on the filter plate 12 can be scraped onto one side of the collecting plate 63. The upper door 1a is opened, and the collecting plate 63 is pulled outward, which drives the receiving plate 64 to move outward. During the outward movement of the receiving plate 64, the slag is also pushed outward, and the slag can be discharged from the extraction tank 1. It is relatively simple and convenient to remove the slag.

[0044] Furthermore, the locking part 65 includes an upper locking channel 651 formed on the connecting rod 62 and a lower locking channel 652 formed on the collecting plate 63. A locking piece 653 is slidably installed on the lower locking channel 652, and a guide rod 654 is fixed on the locking piece 653. A rotating shaft 657 is rotatably installed on the collecting plate 63, and a pull ring 656 is fixed on the rotating shaft 657. A torsion spring 658 is sleeved on the rotating shaft 657. The torsion spring 658 can prevent the pull ring 656 from rotating excessively up and down during rotation, ensuring that the locking piece 653 is stably inserted into the upper locking channel 651. The torsion spring 658 is fixed between the pull ring 656 and the collecting plate 63. A guide channel 655 is formed on the pull ring 656 to cooperate with the guide rod 654. When it is necessary to pull out the collection plate 63, lift the pull ring 656 upwards. The pull ring 656 rotates and drives the locking piece 653 downwards through the transmission of the guide rod 654 and the guide channel 655. The locking piece 653 moves downwards and disengages from the upper locking channel 651, allowing the operator to pull out the collection plate 63. The operation is simple and convenient.

[0045] In this embodiment, a drain pipe is installed below the settling plate 71 in the alcohol precipitation tank 3, and a pump is also installed on the drain pipe to pump out the liquid in the alcohol precipitation tank 3.

[0046] Example 3

[0047] refer to Figures 11-12Similar to Example 1, but with an improvement, the alcohol precipitation tank 3 is equipped with a scraping mechanism 7. The scraping mechanism 7 includes a settling plate 71 fixed inside the alcohol precipitation tank 3, a drain hole 72 opened on the settling plate 71, a scraping part 74 for removing polysaccharide precipitate on the settling plate 71, and a sealing part 73 for sealing the drain hole 72. The scraping part 74 includes a fine-hole scraper 741, a screw 743 rotatably installed inside the alcohol precipitation tank 3, and a guide post 744 fixed inside the alcohol precipitation tank 3. The fine holes on the fine-hole scraper 741 allow the solution to pass through the fine-hole scraper 741, but the polysaccharide precipitate cannot pass through. Two sets of connecting rods 742 are fixed on the fine-hole scraper 741, which are respectively used in conjunction with the screw 743 and the guide post 744. The alcohol precipitation tank 3 is equipped with a motor 745 for driving the screw 743. The sealing part 73 includes a hydraulic rod 731 installed at the bottom of the alcohol precipitation tank 3. A sealing plate 732 that works with the leakage hole 72 is fixed on the movable end of the hydraulic rod 731. The sealing plate 732 has a convex cross section to ensure the flatness of the top surface of the settling plate 71 during sealing, so that the generated polysaccharide precipitate can be easily scraped off. In this process, after the polysaccharide extract and ethanol both enter the alcohol precipitation tank 3, the polysaccharide precipitate forms on the top of the settling plate 71. After the reaction is complete, the motor 745 is started, driving the screw 743 to rotate, which in turn moves the connecting rod 742 towards the lower door 3a. This, in turn, moves the fine-pore scraper 741 towards the lower door 3a. During its movement, the fine-pore scraper 741 gathers the polysaccharide precipitate formed on the top of the settling plate 71 onto the top of the filter plate 12 near the lower door 3a. Then, the hydraulic rod 731 is activated, causing the sealing plate 732 to move down and detach from the drain hole 72. Excess water and ethanol pass through the drain hole 72 and fall to the bottom of the alcohol precipitation tank 3, while the ethanol solution can be discharged from the drain pipe. In this way, the ethanol solution and the polysaccharide precipitate can be separated. After the solution in the alcohol precipitation tank 3 is drained, the lower door 3a is opened, and the fine-pore scraper 741 is moved again to scrape off the polysaccharide precipitate, achieving automated separation that is simple and convenient.

[0048] Example 4

[0049] refer to Figure 10 Similar to Example 1, but with an improvement: the extraction tank 1 is equipped with a clearing mechanism 8, which includes a cross-shaped nozzle 81 installed inside the extraction tank 1. One end of the cross-shaped nozzle 81 extends out of the extraction tank 1 and is equipped with a one-way valve 82. The one-way valve 82 prevents the liquid from flowing out. The extended end of the cross-shaped nozzle 81 is connected to an air duct 83, and the other end of the air duct 83 is connected to a blower 84. When it is necessary to clear the filter plate 12, the blower 84 is started, and air is injected from the air duct 83, passes through the one-way valve 82, enters the cross-shaped nozzle 81, and then sprays out. The airflow quickly passes from the bottom to the top of the filter plate 12, carrying out the material blocking the channels of the filter plate 12, thus clearing the filter plate 12 and preventing severe blockage that would affect the permeation of the polysaccharide extract.

[0050] Specifically, the cross-shaped nozzle 81 is located below the filter plate 12, and the nozzle of the cross-shaped nozzle 81 faces downward. The ejected airflow flows downward, and after being backflushed and diffused by the conical surface at the bottom of the extraction tank 1, the airflow quickly diffuses and flows upward, which can achieve large-area unblocking of the filter plate 12 and improve the unblocking effect.

[0051] The extraction equipment in this invention integrates extraction and alcohol precipitation, improving production efficiency. Furthermore, the pressure filtration process reduces waste of extract and increases polysaccharide yield, while also making the overall operation more convenient.

[0052] All components used in this application are standard parts that can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the existing technology. The machinery, parts and electrical equipment all adopt conventional models in the existing technology.

[0053] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
