Description

Technical Field

[0001] This utility model relates to the field of blueberry leaf polysaccharide purification, specifically a blueberry leaf polysaccharide purification system. Background Technology

[0002] Polysaccharides are formed by the condensation and dehydration of multiple monosaccharide molecules. They are a class of sugar substances with complex and large molecular structures. Traditional polysaccharide extraction methods include hot water extraction, ultrasound-assisted extraction, and enzymatic extraction. The extraction time required by different methods varies, and the polysaccharide extraction yield also varies greatly. Blueberry leaves are used as raw materials for polysaccharide extraction. After drying and crushing the blueberry leaves, water is added and stirred to extract the supernatant. 95% ethanol is added to the supernatant, and the precipitate after centrifugation is the polysaccharide. A purification system is required when extracting the supernatant to prevent impurities from the blueberry leaves from being extracted with the supernatant.

[0003] Existing purification systems for blueberry leaf polysaccharides, such as the licorice crude polysaccharide separation and purification device proposed in patent application number "CN202221953266.4", utilize a processing box, stirring chamber, mixing chamber, and stirring blades. After a second motor starts, a stirring rod drives a fixed component to rotate. The rotating component's external stirring blades stir the water in the stirring chamber. Once the licorice seeds and water are fully mixed, the stirring mechanism is turned off. The extracted water and licorice seeds are then mixed to obtain a crude licorice polysaccharide solution. A pump connected externally to the inlet is then activated to extract the crude licorice polysaccharide solution from the stirring chamber. The licorice seed waste is then discharged through the waste outlet. This facilitates material-liquid separation and cleaning. The stirring mechanism improves the mixing efficiency. A filter and partition divide the processing box into a stirring chamber and a mixing chamber. The stirring blades stir within the stirring chamber, while the filter and partitions stir the raw materials and water in the mixing chamber.

[0004] However, existing technologies have drawbacks. The stirring blades stir the mixture of raw materials and water in the mixing chamber through the filter screen and baffle. The water flow in the mixing chamber is poor, resulting in poor stirring and purification effect and uneven mixing of raw materials and water. Therefore, a purification system for blueberry leaf polysaccharides is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] A purification system for blueberry leaf polysaccharides, such as Figures 1-5As shown, the device includes a cylinder 1, with an inlet 10 fixedly connected to the upper part of the cylinder 1 and an outlet 22 fixedly connected to the lower end of the cylinder 1. The inlet 10 is sealed with a cap, and the outlet 22 is equipped with a valve to control the on / off state. A shaft 5 is rotatably connected to the middle of the cylinder 1, and a pipe 6 is opened in the middle of the shaft 5. An agitator 11 is fixedly connected to the lower end of the shaft 5. A suction port 12 is opened on the side wall of the shaft 5, and a cover 13 is fixedly connected to the side wall of the shaft 5. The suction port 12 is located inside the cover 13 and is used to connect the inside of the cover 13 and the inside of the pipe 6. A filter port 14 is opened through the side wall of the cover 13. A cleaning component for scraping the inner wall of the cylinder 1 is rotatably connected to the side wall of the shaft 5. A drive component is fixedly connected to the upper end of the cylinder 1, and the drive component meshes with the side wall of the shaft 5 for transmission.

[0025] Water and blueberry leaf debris are added to the inside of the cylinder 1 through the feed inlet 10. The discharge outlet 22 and the feed inlet 10 are then sealed. The drive assembly controls the shaft 5 to rotate, causing the stirring paddle 11 to stir the water and debris inside the cylinder 1. The mixture of water and blueberry leaf debris is driven and mixed by the water flow, making the blueberry leaves and water evenly mixed. The cleaning assembly can remove the debris adhering to the side wall of the cylinder 1. After the mixture is evenly mixed, the supernatant enters the cover 13 through the filter port 14. The filter port 14 blocks the debris. The supernatant in the cover 13 is then sucked up through the pipe 6 and the suction port 12 to remove the debris, thereby purifying the blueberry leaf polysaccharide extract and preventing debris from being carried in during the extraction of the supernatant. The water flow for mixing the mixture is stronger, the stirring and purification effect is improved, and the extracted supernatant is purer, making it easier to add ethanol and centrifuge later.

[0026] like Figures 2-4 As shown, a fixed disk 15 is fixedly connected to the side wall of the shaft 5. The cleaning assembly includes a turntable 16, which is rotatably connected to the fixed disk 15. A connecting rod 23 is fixedly connected to the side wall of the turntable 16, and a scraper 24 is fixedly connected to the end of the connecting rod 23. The scraper 24 is used to scrape the inner wall of the cylinder 1.

[0027] The shaft 5 drives the scraper 24 to scrape the inner wall of the cylinder 1 via the fixed disk 15, the turntable 16, and the connecting rod 23. The scraper 24 rotates 360 degrees around the shaft 5 to prevent debris from sticking to the inner wall of the cylinder 1.

[0028] like Figure 3 As shown, a limiting ring 19 is fixedly connected to the side wall of the fixed disk 15, and the limiting ring 19 is rotatably connected to the inner wall of the turntable 16.

[0029] The limiting ring 19 prevents the fixed plate 15 and the turntable 16 from separating.

[0030] like Figures 3-5 As shown, the inner wall of the turntable 16 has multiple sets of slots 17, and the side wall of the fixed plate 15 has multiple sets of grooves. Each set of grooves has a right-angled trapezoidal elastic block 18 fixed inside, and the ends of the multiple sets of right-angled trapezoidal elastic blocks 18 are respectively engaged with the multiple sets of slots 17.

[0031] When the shaft rotates clockwise, the right-angled surface of the right-angled trapezoidal elastic block 18 abuts against the inner wall of the slot 17, driving the turntable 16 to rotate with the fixed plate 15. When the shaft rotates counterclockwise, the inclined surface of the right-angled trapezoidal elastic block 18 abuts against and presses against the inner wall of the slot 17, causing the right-angled trapezoidal elastic block 18 to retract into the groove. The fixed plate 15 will not drive the turntable 16 to rotate, thus allowing free control over whether the cleaning component operates.

[0032] like Figures 2-3 As shown, both the fixed disk 15 and the turntable 16 have annular grooves at their upper ends, and sealing rings 21 are snapped into the interior of both sets of annular grooves. A sealing gasket 20 is fixed between the two sets of sealing rings 21.

[0033] The sealing ring 21 is snapped into and rotatably connected to the turntable 16 or the fixed plate 15. When the fixed plate 15 rotates, the sealing ring 21 can rotate relative to the fixed plate 15. When the turntable 16 rotates, the sealing ring 21 can rotate relative to the turntable 16. The sealing ring 21 and the sealing gasket 20 seal the space between the fixed plate 15 and the turntable 16, preventing water from entering between the fixed plate 15 and the turntable 16.

[0034] like Figure 1 As shown, a second gear 7 is fixedly connected to the upper side wall of the shaft 5. The second gear 7 is rotatably connected to the upper end of the cylinder 1. A retaining frame 8 for limiting the second gear 7 is fixedly connected to the upper end of the cylinder 1. The drive assembly includes a bracket 2, which is fixedly connected to the upper end of the cylinder 1. A servo motor 3 is fixedly connected to the bracket 2. A first gear 4 is fixedly connected to the output end of the servo motor 3. The first gear 4 meshes with the second gear 7 for transmission.

[0035] Servo motor 3 (model 110ST-M05030) controls gear 4 to rotate, gear 4 meshes with transmission gear 7, gear 7 controls shaft 5 to rotate, thereby driving shaft 5 to rotate.

[0036] The working principle of the blueberry leaf polysaccharide purification system provided by this utility model is as follows:

[0037] Water and blueberry leaf debris are added to the inside of the cylinder 1 through the feed inlet 10. The drive component controls the shaft 5 to rotate, causing the stirring paddle 11 to stir the water and debris inside the cylinder 1, making the blueberry leaves and water evenly mixed. The cleaning component can remove the debris adhering to the side wall of the cylinder 1. After the mixture is evenly mixed, the supernatant enters the cover 13 through the filter port 14. The supernatant in the cover 13 is then sucked up through the pipe 6 and the suction port 12 to remove debris, thereby purifying the blueberry leaf polysaccharide extract. This also prevents debris from being carried in during the extraction of the supernatant, strengthens the water flow of the mixture, and improves the stirring and purification effect.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
