Description

Technical Field

[0001] This invention relates to the field of plant material extraction technology, and in particular to a device for extracting Polygonatum polysaccharides. Background Technology

[0002] Since Polygonatum polysaccharide is the core active ingredient of Polygonatum and has important application value, and it needs to be efficiently separated and extracted to meet relevant needs, a Polygonatum polysaccharide extraction device was established to perform pretreatment, extraction, separation and purification of Polygonatum raw materials, so as to realize the efficient enrichment and preparation of Polygonatum polysaccharide, and provide a material basis for its application in food, medicine and other fields.

[0003] A search revealed Chinese patent publication number CN212128040U, which discloses a plant polysaccharide extraction device. This device includes a main body and a stirrer. The main body comprises a reaction vessel and a precipitation vessel, with the reaction vessel positioned above the precipitation vessel. A movable baffle and a filter screen are sequentially arranged between the reaction vessel and the precipitation vessel; the movable baffle controls the connection between the reaction vessel and the precipitation vessel. The stirrer is located within the main body and is used to stir the substances within the reaction vessel and the precipitation vessel. This plant polysaccharide extraction device integrates the reaction vessel and precipitation vessel, simplifying the polysaccharide extraction process, reducing human intervention and the use of multiple devices, and improving the automation of the polysaccharide extraction process, thereby increasing extraction efficiency. Furthermore, it reduces human contact from raw material (oil cake) to polysaccharide product, thus reducing contamination and ensuring product hygiene.

[0004] The aforementioned patent has the following shortcomings: the existing device is not convenient for filtering Polygonatum fragments. Since the existing device only relies on a single filter screen to filter the fine fragments after Polygonatum is crushed, the filtration accuracy and interception effect are limited. When the filtration accuracy is too low, fine fragments and impurities cannot be effectively intercepted and are easily mixed into the extract, affecting the purity of Polygonatum polysaccharide and subsequent purification efficiency. When the filtration accuracy is too high, it will cause the flow of the extract to be obstructed and the filtration speed to slow down. At the same time, the filtered residue is prone to causing frequent clogging of the filter screen, reducing the continuous operating efficiency of the device and increasing cleaning and maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for extracting Polygonatum polysaccharides.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for extracting Polygonatum polysaccharides includes a tank and further includes: The top cover is fixed to the top of the tank body by bolts.

A connecting rod is fixed to the bottom end of the stirring rod, and a spiral blade is fixed to the outside of the connecting rod. A sealing sleeve that is pluggable and pluggable to the slag collection tube is fixed inside the bottom cover, and a positioning post that is rotatably connected to the connecting rod is fixed to the top end of the bottom cover.

[0009] Based on the aforementioned scheme: the cleaning assembly includes a scraper fixed to the outside of the stirring rod, a guide roller fixed to the bottom of the inside of the fixing ring, a rotating ring slidably connected to the outside of the guide roller, a rotating plate fixedly connected to the rotating ring between the fine filter screen and the coarse filter screen, a reinforcing ring fixed to the outside of the rotating plate, brushes fixed to both sides of the rotating plate, a driven magnet fixed to the side of the rotating plate near the scraper, an active magnet magnetically coupled to the driven magnet fixed to the outside of the scraper near the driven magnet, and a slag discharge groove opened at the top of the inside of the slag storage tube.

[0010] A better embodiment of the aforementioned scheme is that both the scraper and the rotating blade are spiral-shaped, and the scraper and the rotating blade are arranged in a ring with equal spacing inside the fine filter screen.

[0011] As a further aspect of the present invention: the connecting rod and the spiral blade are integrally formed, the pitch of the spiral blade gradually decreases along the filter cake conveying direction, and the diameter of the connecting rod increases synchronously along the filter cake conveying direction.

[0012] Meanwhile, the vibrating structure includes a drive shaft fixed to the end of the output shaft of the drive motor. A drive gear is fixed to the outer side of the top of the drive shaft.

[0013] As a preferred embodiment of the present invention: the protective shell is connected to the top cover by bolts, and the interior of the protective shell is provided with through holes that match the drive shaft and the positioning rod, and the drive shaft is connected to the stirring rod by a coupling.

[0014] Meanwhile, the mixing structure includes a conveying pipe fixed to one side of the top of the top cover and connected to the hopper. An outer shell is fixed to the outside of the conveying pipe, and a water injection pipe is connected to one side of the outer shell. A mixing plate is fixed to the bottom of the inside of the conveying pipe. A baffle is rotatably connected to one side of the bottom of the conveying pipe. A tension spring connected to the conveying pipe is fixed to one side of the baffle. Water injection holes are opened on the outer wall of the conveying pipe.

[0015] As a preferred embodiment of the present invention: the outer shell is connected to the conveying pipe through water injection holes, and the water injection holes are arranged at equal intervals on the outside of the conveying pipe.

[0016] The beneficial effects of this invention are as follows: 1. This invention uses a coarse filter to intercept larger particulate impurities, followed by a fine filter to intercept fine debris. Simultaneously, a stirring rod drives a scraper and a brush to rotate synchronously, cleaning the surfaces of both sets of filter screens. This achieves the high-efficiency filtration function of the device, improves the filtration efficiency of Polygonatum polysaccharide extract, and automatically cleans the surfaces of both sets of filter screens to prevent clogging, ensure smooth flow of the extract, maintain continuous and stable operation of the device, and reduce the frequency of manual cleaning and maintenance costs.

[0017] 2. In this invention, the filter residue is pushed downward by the spiral blades, so that the filter residue is gradually squeezed in the residue storage tube under the combined action of the connecting rod. At the same time, the filter screen filters the extract that precipitates during the squeezing process, thereby realizing the filter residue compression function of this device. It can squeeze the filtered Polygonatum sibiricum filter residue to fully extract the residual polysaccharide extract in the filter residue. At the same time, the volume of the compressed filter residue is greatly reduced, which facilitates centralized collection, transportation and subsequent processing.

[0018] 3. In this invention, the drive motor is started to drive the transmission shaft to rotate, which causes the push arm to drive the swing frame to rotate back and forth. The ultrasonic waves emitted by the ultrasonic vibrator are evenly applied to the material, thereby realizing the ultrasonic separation function of this device. This allows the ultrasonic waves to act evenly on the material, efficiently destroy the cell structure of Polygonatum odoratum, accelerate the dissolution of polysaccharide components, and greatly improve the extraction rate and extraction yield.

[0019] 4. In this invention, solvent water is injected into the outer shell through the water injection pipe, causing the water flow to disperse the Polygonatum fragments passing through the feed pipe. At the same time, the mixing plate breaks up the stratification between the Polygonatum fragments and water, improving the mixing efficiency. This realizes the mixing structure function of this device, which allows the raw materials and solvent to quickly form a uniform suspension system, avoids the agglomeration and accumulation of Polygonatum fragments, and shortens the initial mixing time, allowing the extraction process to start quickly.

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example

[0024] A device for extracting Polygonatum polysaccharides, such as Figures 1 to 9 As shown, including tank 1, it also includes: The top cover 13 is fixed to the top of the tank body 1 by bolts. A drive motor 11 is installed on the top of the top cover 13, and a hopper 10 is provided on one side of the top of the top cover 13. The mixing structure 8, used for the initial mixing of solvent and Polygonatum sibiricum powder, is located at the bottom of the hopper 10; The vibrating structure 7, which is used to accelerate the dissolution of polysaccharide components in Polygonatum odoratum fragments, is set at the rotating end of the drive motor 11; A stirring rod 5 is set at the bottom end of the vibrating structure 7, and a stirring blade 21 is fixed on the outside of the stirring rod 5; Bottom cover 16 is detachably installed at the bottom of tank body 1. Opening and closing components are provided on both sides of bottom cover 16, and a drain port 22 is fixed on one side of the bottom end of bottom cover 16. Separation structure 4 is set inside the tank body 1. Separation structure 4 includes a fixing ring 403 fixed inside the tank body 1. A fine filter screen 401 is fixed at the bottom end of the fixing ring 403. A coarse filter screen 402 fixedly connected to the fixing ring 403 is set inside the fine filter screen 401. A cleaning component is set inside the fine filter screen 401. A compression structure 6, used to compress the filter residue filtered by the separation structure 4, is located at the bottom of the fine filter screen 401.

[0025] A support lug 9 is fixed to the top of the outer side of the tank body 1. A water injection jacket 2 is fixed to the outer side of the tank body 1. A manhole 12 is fixed to one side of the top of the top cover 13. The opening and closing assembly includes a first rotating frame 15 fixed to one side of the water injection jacket 2. A first hydraulic cylinder 14 is rotatably connected to the bottom end of the first rotating frame 15. A rotating frame 3 fixedly connected to the bottom cover 16 is rotatably connected to the telescopic end of the first hydraulic cylinder 14. The rotating frame 3 and the water injection jacket 2 form a rotating structure. A second hydraulic cylinder 17 is rotatably connected to the other side of the water injection jacket 2. A second rotating frame 18 rotatably connected to the water injection jacket 2 is rotatably connected to the telescopic end of the second hydraulic cylinder 17. A buckle plate 20 is fixed inside one side of the second rotating frame 18. A buckle seat 19 that is fastened to the buckle plate 20 is fixed to the side of the bottom cover 16 near the buckle plate 20.

[0026] In this embodiment, the device is fixed in the designated working position by the lugs 9 to prevent shaking during operation. The manhole 12 can be opened to inspect and maintain the inside of the tank 1. By introducing liquid of appropriate temperature into the water injection jacket 2, the material inside the tank 1 is indirectly heated through heat exchange, providing a stable and suitable temperature environment for the extraction process. By pouring Polygonatum sibiricum fragments into the hopper 10, the mixing structure 8 mixes water and Polygonatum sibiricum fragments and injects them into the tank 1. The drive motor 11 is started to make the stirring rod 5 drive the stirring blade 21 to stir the water and Polygonatum sibiricum fragments. When it is necessary to clean the filter residue, the second rotating frame 18 is pulled to rotate around the water injection jacket 2, so that the buckle 20 and the buckle seat 19 are disengaged. Then, the first hydraulic cylinder 14 is controlled to retract, which drives the rotating frame 3 and the bottom cover 16 to flip and open the bottom cover 16.

[0027] To solve the problem of poor filtration efficiency; such as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the cleaning assembly includes a scraper 407 fixed to the outside of the stirring rod 5, a guide roller 406 fixed to the bottom of the fixed ring 403, a rotating ring 405 slidably connected to the outside of the guide roller 406, a rotating blade 408 fixedly connected to the rotating ring 405 and disposed between the fine filter screen 401 and the coarse filter screen 402, a reinforcing ring 409 fixed to the outside of the rotating blade 408, brushes 412 fixed to both sides of the rotating blade 408, a driven magnet 411 fixed to the side of the rotating blade 408 near the scraper 407, an active magnet 410 magnetically coupled to the driven magnet 411 fixed to the outside of the scraper 407 near the driven magnet 411, and a slag discharge groove 404 opened at the top of the slag storage tube 606. The scraper 407 and the rotating blade 408 are both spiral structures, and the scraper 407 and the rotating blade 408 are arranged in a ring at equal intervals inside the fine filter screen 401.

[0028] In this embodiment, after the material is extracted by vibration, the extract and the Polygonatum odoratum filter residue flow downwards to the separation structure 4. Larger particles in the material are first intercepted by the coarse filter screen 402, followed by precise filtration of fine debris by the fine filter screen 401, achieving separation of the extract and filter residue. Simultaneously, the stirring rod 5 drives the scraper 407 to rotate synchronously. The scraper 407 rotates against the inner wall of the coarse filter screen 402, scraping away the filter residue adhering to the inner wall of the coarse filter screen 402, preventing filter residue from accumulating and clogging the filter screen pores. Magnetic coupling is generated between the active magnet 410 and the driven magnet 411, causing the scraper 407 to... The rotating plate 408 and the brushes 412 on both sides rotate. One side of the brush 412 is attached to the outer wall of the coarse filter screen 402 and the other side is attached to the inner wall of the fine filter screen 401. During the rotation, the surface of the filter screens on both sides is swept and cleaned to remove the attached fine debris. The scraper 407 and the rotating plate 408 have a spiral structure. During the rotation, the filter residue is pushed downward. The filter residue between the coarse filter screen 402 and the fine filter screen 401 can be discharged into the inside of the slag storage pipe 606 through the slag discharge groove 404, which avoids the filter screen from clogging to a certain extent and ensures the smooth flow of the extract. At the same time, the filter residue can be pushed into the inside of the compression structure 6 for subsequent processing.

[0029] To solve the problem of filter residue easily clogging the filter screen; such as Figure 7 As shown, the compression structure 6 includes a slag collection tube 606 fixed to the bottom of the fine filter screen 401 and the coarse filter screen 402. Filter screens 605 are fixed on the outer side wall of the slag collection tube 606. A connecting rod 601 is fixed to the bottom of the stirring rod 5. A spiral blade 602 is fixed to the outside of the connecting rod 601. A sealing sleeve 603 that is pluggable and pluggable to the slag collection tube 606 is fixed inside the bottom cover 16. A positioning post 604 that is rotatably connected to the connecting rod 601 is fixed to the top of the bottom cover 16. The connecting rod 601 and the spiral blade 602 are integrally formed. The pitch of the spiral blade 602 gradually decreases along the direction of filter residue conveying, and the diameter of the connecting rod 601 increases synchronously along the direction of filter residue conveying.

[0030] In this embodiment, the filter residue enters the storage tube 606 along the inner walls of the fine filter screen 401 and the coarse filter screen. At the same time, the stirring rod 5 drives the connecting rod 601 and the spiral blade 602 to rotate. The spiral blade 602 pushes the filter residue downward. As the pitch of the spiral blade 602 gradually decreases along the filter residue conveying direction and the diameter of the connecting rod 601 increases synchronously, the filter residue is gradually squeezed in the storage tube 606. The filter screen 605 on the outside of the storage tube 606 filters out the residual extract that precipitates during the squeezing process and collects it with the previous extract. Meanwhile, the sealing sleeve 603 ensures the sealing of the bottom of the storage tube 606, and the positioning column 604 provides stable support for the connecting rod 601. To a certain extent, the residual polysaccharides in the filter residue are fully extracted, improving the raw material utilization rate. At the same time, the volume of the compressed filter residue is reduced, which facilitates subsequent centralized cleaning, thereby achieving the dual effect of filter residue treatment and residual polysaccharide recovery. Example

[0031] A device for extracting Polygonatum polysaccharides, such as Figure 8 As shown, in order to improve extraction efficiency, this embodiment makes the following improvements based on embodiment 1: The vibrating structure 7 includes a transmission shaft 709 fixed to the end of the output shaft of the drive motor 11. A transmission gear 702 is fixed to the outer side of the top of the transmission shaft 709. A positioning rod 704 is rotatably connected to the top of the inside of the top cover 13. A driven gear 703 that meshes with the transmission gear 702 is fixed to the outer side of the positioning rod 704. A cam 705 is fixed to the bottom end of the positioning rod 704. The outer side of the transmission shaft 709 rotates... A swing frame 701 is connected, and a push arm 706 that is rotatably connected to a cam 705 is rotatably connected to one side of the top of the swing frame 701. Ultrasonic vibrating rods 707 are installed inside both sides of the swing frame 701. A protective shell 708 is fitted on the outside of the transmission gear 702 and the driven gear 703. The protective shell 708 is connected to the top cover 13 by bolts. Through holes matching the transmission shaft 709 and the positioning rod 704 are opened inside the protective shell 708. The transmission shaft 709 is connected to the stirring rod 5 by a coupling.

[0032] In this embodiment, when the material enters the tank 1, the drive motor 11 is started to drive the transmission shaft 709 to rotate, causing the transmission gear 702 on the outside of the transmission shaft 709 to mesh and drive the driven gear 703 and the positioning rod 704 to rotate. At the same time, the cam 705 pushes the push arm 706 to drive the swing frame 701 to rotate back and forth, so that the ultrasonic vibrating rods 707 on both sides of the swing frame 701 swing back and forth. The ultrasonic waves emitted by the ultrasonic vibrating rods 707 can be evenly applied to the material. The vibration of the ultrasonic waves destroys the structure of Polygonatum cells. At the same time, the stirring rod 5 and the stirring blade 21 rotate with the transmission shaft 709, which to a certain extent accelerates the dissolution of Polygonatum polysaccharide components from the cells, thereby increasing the polysaccharide extraction rate and extraction amount. Meanwhile, the gentle vibration method avoids damage to the polysaccharide activity.

[0033] To address the issue of improving extraction efficiency; such as Figure 9 As shown: The mixing structure 8 includes a conveying pipe 806 fixed to one side of the top of the top cover 13 and connected to the hopper 10. An outer shell 801 is fixed to the outside of the conveying pipe 806. A water injection pipe 807 is connected to one side of the outer shell 801. A mixing plate 803 is fixed to the bottom of the inside of the conveying pipe 806. A baffle 804 is rotatably connected to one side of the bottom of the conveying pipe 806. A tension spring 805 connected to the conveying pipe 806 is fixed to one side of the baffle 804. Water injection holes 802 are opened on the outer wall of the conveying pipe 806. The outer shell 801 is connected to the conveying pipe 806 through the water injection holes 802. The water injection holes 802 are arranged at equal intervals on the outside of the conveying pipe 806.

[0034] In this embodiment, when raw materials are fed, Polygonatum sibiricum fragments are added to the conveying pipe 806 through the hopper 10, while solvent water is injected into the outer casing 801 through the water injection pipe 807. The water flows into the conveying pipe 806 through the water injection hole 802 on the outside of the conveying pipe 806 and meets the Polygonatum sibiricum fragments, dispersing them. At the same time, the mixing plate 803 inside the conveying pipe 806 mixes the falling Polygonatum sibiricum fragments with the water, so that the Polygonatum sibiricum fragments and solvent water come into full contact during the falling process, initially achieving uniform mixing of raw materials and solvent. Then, under the action of the raw material's gravity, the baffle 804 overcomes the elastic force of the tension spring 805 and rotates downward, opening the channel of the conveying pipe 806. The raw material and the synchronously injected solvent water fall smoothly and mix. When feeding stops, the tension spring 805 returns to its original position and contracts, pulling the baffle 804 to seal the port of the conveying pipe 806, preventing steam or odor from the inside of the tank 1 from overflowing upwards to a certain extent.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
