Description

Technical Field

[0001] This invention belongs to the field of seaweed polysaccharide purification technology, specifically relating to a seaweed polysaccharide purification device for testing the antiviral activity of seaweed polysaccharides. Background Technology

[0002] The main purpose of purifying seaweed polysaccharides is to remove impurities, improve the purity and bioactivity of the polysaccharides, thereby enhancing their effectiveness in various applications. The purification process involves multiple extractions, separations, precipitation, washing, and purification steps to gradually increase the purity of the polysaccharides. High-purity polysaccharides are easier to analyze structurally and study in terms of bioactivity.

[0003] In the purification of seaweed polysaccharides, the Buchner funnel, through the negative pressure generated by the vacuum pump, can quickly separate solid impurities (such as unbroken seaweed particles, proteins, lipids, etc.) from the polysaccharide solution in the extract. The Buchner funnel can effectively remove insoluble impurities in the extract, such as fibers and cell debris, thereby improving the purity of the polysaccharide.

[0004] Most existing funnel separation structures have fixed separation apertures. When seaweed needs to be separated, if the aperture is too large, additional filter paper needs to be added for separation. Although the separation effect can be achieved, there is a certain gap between the filter paper and the funnel. Seaweed can easily pass through the gap and fall down with the separated seaweed, thus reducing the separation effect. Utility Model Content

[0005] The purpose of this invention is to provide a purification device for seaweed polysaccharide in antiviral activity testing. This device can adjust the appropriate filter pore size according to the separation requirements of seaweed to perform coarse and fine filtration, effectively improving the separation effect.

[0008] A fine filter plate is provided between the upper annular plate and the feeding hopper, and an aperture adjustment plate is fixedly connected to the inner wall of the lower annular plate. The aperture adjustment plate abuts against the fine filter plate, and an angle positioning component is provided between the feeding hopper and the lower annular plate.

[0009] The annular plate on the upper side is threadedly connected to the feeding hopper.

[0010] The elastic element includes a plurality of first springs fixedly connected to the bottom surface of the annular groove. The top end of the first spring is fixedly connected to the coarse filter plate. The upper and lower sidewalls of the coarse filter plate are respectively fixedly connected to annular shielding curtains, and the other end of each annular shielding curtain is fixedly connected to the sidewall of the annular groove.

[0022] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a seaweed polysaccharide purification device for antiviral activity testing of seaweed polysaccharides includes a feeding hopper 1 and a discharging hopper 2. An adjusting ring 3 is rotatably connected between the feeding hopper 1 and the discharging hopper 2. The adjusting ring 3 is composed of two annular plates. An annular groove 6 is opened on the inner wall of the feeding hopper 1. A coarse filter plate 4 is installed in the annular groove 6. An elastic element is installed in the annular groove 6.

[0024] A fine filter plate 8 is provided between the upper annular plate and the feeding hopper 1, and an aperture adjustment plate 9 is fixedly connected to the inner wall of the lower annular plate. The aperture adjustment plate 9 abuts against the fine filter plate 8. An angle positioning component is provided between the feeding hopper 2 and the lower annular plate. Several holes are opened on the surface of both the fine filter plate 8 and the aperture adjustment plate 9.

[0025] like Figure 2 and Figure 3 As shown, the upper annular plate is threadedly connected to the feed hopper 1. This threaded connection facilitates the separation of the feed hopper 1 from the adjusting ring 3, allowing for easy removal of the fine filter plate 8 for cleaning or replacement, thus extending its service life.

[0026] like Figure 3 As shown, the elastic element includes multiple first springs 7 fixedly connected to the bottom surface of the annular groove 6. The top end of the first spring 7 is fixedly connected to the coarse filter plate 4. Annular baffle curtains 5 are fixedly connected to the upper and lower side walls of the coarse filter plate 4, and the other end of each annular baffle curtain 5 is fixedly connected to the side wall of the annular groove 6. The elastic element facilitates pressing down on the coarse filter plate 4 using a stirring plate or other tools. This serves two purposes: firstly, it helps to squeeze out particles or flocculent algae accumulated on the surface of the fine filter plate 8 to aid in separation; secondly, it facilitates shaking large algae particles on the coarse filter plate 4 to prevent clogging.

[0027] like Figure 4 As shown, the angle positioning component includes a groove 10 formed on the top end face of the hopper 2. A second spring 11 is fixedly connected to the bottom surface of the groove 10, and a locking block 12 is fixedly connected to the top surface of the second spring 11. Several locking slots 13 are formed on the bottom surface of the lower annular plate. The end face of the locking block 12 has an arc-shaped structure, and the locking block 12 is adapted to the locking slot 13. The arc-shaped structure facilitates the locking block 12 to disengage and engage with the locking slot 13.

[0028] The rotation angle of the aperture adjustment plate 9 can be adjusted by using the angle positioning component, so that the holes on the surface of the aperture adjustment plate 9 and the fine filter plate 8 are in an interlaced state. The larger the interlacing angle, the smaller the aperture, and vice versa.

[0029] like Figure 4 As shown, both the feeding hopper 1 and the upper annular plate have a stepped structure, with the fine filter plate 8 located between the feeding hopper 1 and the annular plate. This allows the fine filter plate 8 to be easily inserted between the two, achieving both cleaning and maintenance, as well as replacement, effectively improving the separation effect.

[0030] The working principle of this utility model is as follows: First, select a suitable fine filter plate 8 according to the filtration requirements and place it in the stepped groove on the upper annular plate. Then, connect the upper annular plate to the feeding hopper 1 by thread. Then, rotate the adjusting ring 3 to drive the aperture adjusting plate 9 to rotate. The locking block 12 is pushed into the groove 10, and at the same time, the second spring 11 is compressed, and the locking block 12 is disengaged from the slot 13. When the aperture adjusting plate 9 rotates to the specified angle, the second spring 11 rebounds and drives the locking block 12 to be locked into the slot 13, so that the aperture adjusting plate 9 and the holes on the fine filter plate 8 are in an alternating state, thereby realizing the change of aperture. During the seaweed filtration process, the coarse filter plate 4 can be pressed down with an external tool. The coarse filter plate 4 moves downward, and at the same time, the first spring 7 is compressed. If there are particles or flocculent seaweed accumulated on the surface of the fine filter plate 8, the residual liquid in the seaweed can be squeezed to assist in separation.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
