[0002] Alginate is a natural bioactive substance extracted from marine algae. It has a variety of biological activities, such as anti-oxidation, anti-tumor, anti-inflammatory, and antibacterial effects. During production, it needs to be extracted using an algae extraction device. Existing algae extraction devices mainly include an algae crushing device at the front end, a filtrate device in the middle, a three-stage extraction device and a circulation device at the tail end.

[0003] When using this seaweed extraction device, the crushed seaweed needs to be transported to the filtration device for filtration.

[0016] The beneficial effects of this invention are:

[0017] (1) The seaweed extraction device for seaweed extracting phycocyanin described in this invention, by setting up a crushing mechanism, etc., during extraction, the seaweed crushed by the crushing device is transported to the first filter screen in the filtrate tank through the feed pipe. When it is necessary to crush the large pieces of seaweed on the first filter screen, the motor is started. The rotation of the motor drives the rotation of the threaded rod, thereby driving the first moving plate to move downward, and driving the crushing plate to move downward through the first spring. When the crushing plate comes into contact with the seaweed, the first spring can be gradually compressed. At the same time, when the first moving plate moves downward, the first pushing plate moves downward synchronously through the L-shaped plate, so that the lower end of the first pushing plate comes into contact with the inclined plate, thereby pushing the second support block to move. The fifth spring is compressed, causing the third inclined plane to slide against the side wall of the sliding plate and slide the supporting surface to the bottom of the sliding plate to support the first filter screen. When the L-shaped plate moves downward, it drives the first connecting plate to move downward synchronously. When the protrusion abuts against the side wall of the sliding plate, it pushes the first filter screen to move. At the same time, the third spring is compressed. When the protrusion passes the side wall of the sliding plate, the first filter screen can move and reset under the action of the third spring. This process is repeated so that when the crushing plate crushes the seaweed, the first filter screen can move back and forth, making the crushing efficiency higher and the effect better. This results in more complete filtrate, avoids waste, and ensures the extraction efficiency and effect of seaweed extract.

[0018] (2) The seaweed extraction alginate device of the present invention, by setting a scraping mechanism, etc., before crushing, when the L-shaped plate moves downward, the second connecting plate drives the second pushing plate to move downward synchronously. When the fourth inclined surface below abuts against the side wall of the second moving plate, it pushes the second moving plate and the scraper to move. At the same time, the sixth spring is compressed. When the second moving plate passes the second pushing plate, the second moving plate and the scraper can move and reset under the action of the sixth spring, so that the seaweed on the first filter screen can be scraped before crushing, ensuring the efficiency and effect of crushing.

[0019] (3) The seaweed extraction alginic acid device of the present invention, by setting a clamping mechanism and a first pushing mechanism, etc., when it is necessary to install the multi-stage filter screen, one side of the multi-stage filter screen abuts against the first inclined surface and slides on its surface, and pushes the rubber block to move closer to the first support block. At the same time, the fourth spring is compressed. After the multi-stage filter screen is inserted into the first slot and the second slot, the rubber block extends under the action of the fourth spring, and the limiting surface abuts against the side wall of the multi-stage filter screen, which can limit the multi-stage filter screen and prevent the multi-stage filter screen from detaching. When disassembling the filter screen, pull the second T-shaped guide rod to retract the rubber block, which facilitates the installation and disassembly of the multi-stage filter screen. When disassembling the first filter screen, since there is crushed seaweed remaining on the top of the first filter screen, when the first filter screen comes into contact with the second inclined surface, it is pushed downward. At the same time, the second spring is compressed, the telescopic cover retracts, and the first filter screen slides at the bottom of the second inclined surface, ensuring that there is a distance between the first filter screen and the top of the first slot, preventing seaweed from being scraped into the filtrate tank, and ensuring the efficiency and effectiveness of cleaning.

The support frame 18 is inserted into the first slot 11, and a telescopic cover 16 is fixedly connected between the support frame 18 and the first filter screen 1301. The side wall of the multi-stage filter screen 13 is fixedly connected with a handle 14, and the side wall of the filtrate tank 102 is provided with a first pushing mechanism for pushing the first filter screen 1301 downward. The top of the filtrate tank 102 is provided with a crushing mechanism for crushing seaweed.

[0035] The crushing mechanism includes a first movable plate 17 disposed within the filtrate tank 102, and the first movable plate 17 is connected to the top of the filtrate tank 102 via a lifting mechanism. A plurality of first springs 20 are fixedly connected to the bottom of the first movable plate 17, and a crushing plate 19 is fixedly connected to the lower end of each first spring 20. A second pushing mechanism for moving the first filter screen 1301 is disposed at the top of the first movable plate 17. A support mechanism for supporting the first filter screen 1301 is disposed on the side wall of the filtrate tank 102, and a crushing plate 19 is disposed on the side wall of the first filter screen 1301 for moving the first filter screen 1301. The scraping mechanism for leveling the seaweed on the first filter screen 1301 facilitates the installation and disassembly of the multi-stage filter screen 13, making it easy to clean. During filtration, it can level the seaweed on the first filter screen 1301, ensuring filtration efficiency and effectiveness. At the same time, it can crush the seaweed on the first filter screen 1301, and during crushing, it can make the first filter screen 1301 move back and forth, making the crushing efficiency higher and the effect better, thus making the filtrate more complete, avoiding waste, and ensuring the extraction efficiency and effect of seaweed extract.

[0036] The first reset mechanism includes a first connecting block 201 fixedly connected to the side wall of the first filter screen 1301, and two symmetrically arranged first sleeves 202 are fixedly connected to the bottom of the first connecting block 201. A first sleeve rod 203 is inserted into the first sleeve 202. The lower end of the first sleeve rod 203 is fixed to the top of the moving block 15. A second spring 204 is sleeved on the side wall of the first sleeve 202, which plays a guiding and reset role in the lifting and lowering of the first filter screen 1301.

[0037] The second reset mechanism includes two symmetrically arranged first T-shaped guide rods 301 fixedly connected to the side wall of the moving block 15, and an L-shaped second connecting block 302 is sleeved on the side wall of the first T-shaped guide rod 301. The second connecting block 302 is fixed to the side wall of the support frame 18, and a third spring 303 is sleeved on the side wall of the first T-shaped guide rod 301, which guides and resets the movement of the first filter screen 1301.

[0038] The clamping mechanism includes a first support block 401 fixedly connected to the side wall of the filtrate tank 102, and two symmetrically arranged second T-shaped guide rods 402 inserted into the side wall of the first support block 401. A fourth spring 405 is sleeved on the side wall of the second T-shaped guide rod 402, and a rubber block 403 is fixedly connected to one end of the second T-shaped guide rod 402. The rubber block 403 includes a first inclined surface 404 and a limiting surface 406. When the multi-stage filter screen 13 needs to be installed, one side of the multi-stage filter screen 13 abuts against the first inclined surface 404 and slides on its surface, pushing the rubber block 403 to move closer to the first support block 401. When the fourth spring 405 is compressed, after the multi-stage filter 13 is inserted into the first slot 11 and the second slot 12, the rubber block 403 extends under the action of the fourth spring 405, and the limiting surface 406 abuts against the side wall of the multi-stage filter 13, which can limit the multi-stage filter 13 and prevent it from detaching. When it is necessary to disassemble the multi-stage filter 13, pull the second T-shaped guide rod 402 to retract the rubber block 403, which facilitates the installation and disassembly of the multi-stage filter 13. In addition, when the first filter 1301 moves, the rubber block 403 can deform to ensure the normal movement of the first filter 1301.

[0039] The first pushing mechanism includes a third connecting block 501 fixedly connected to the side wall of the filtrate tank 102, and a pushing block 502 fixedly connected to the side wall of the third connecting block 501. The pushing block 502 includes two symmetrically arranged second inclined surfaces 503. When disassembling, when the first filter screen 1301 abuts against the second inclined surface 503, the first filter screen 1301 is pushed to move downward. At the same time, the second spring 204 is compressed, the telescopic cover 16 retracts, and the first filter screen 1301 slides at the bottom of the second inclined surface 503, ensuring that the first filter screen 1301 is kept at a distance from the top of the first slot 11, preventing seaweed from being scraped into the filtrate tank 102, and ensuring the efficiency and effect of cleaning.

[0040] The lifting mechanism includes a second sleeve rod 602 fixedly connected to the top of the filtrate tank 102, and a second sleeve 601 sleeved on the side wall of the second sleeve rod 602. The lower end of the second sleeve 601 is fixedly connected to the top of the first moving plate 17, and a threaded pipe 603 is fixedly connected to the top of the first moving plate 17. A threaded rod 604 is threadedly connected to the threaded pipe 603, and the upper end of the threaded rod 604 is rotatably connected to the top of the filtrate tank 102. A motor 605 is fixedly connected to the top of the filtrate tank 102. When the motor 605 is started, the rotation of the motor 605 drives the rotation of the threaded rod 604, thereby driving the first moving plate 17 to rise and fall, and driving the crushing plate 19 to rise and fall through the first spring 20.

[0041] The second pushing mechanism includes an L-shaped plate 701 inserted into the top of the filtrate tank 102, and a first connecting plate 702 is fixedly connected to the side wall of the L-shaped plate 701. A plurality of arrayed protrusions 705 are fixedly connected to the side wall of the first connecting plate 702. A sliding groove 703 is formed in the side wall of the filtrate tank 102, and a sliding plate 704 is slidably connected within the sliding groove 703. The sliding plate 704 is fixed to the side wall of the first filter screen 1301. When the L-shaped plate 701 moves downward, it drives the first connecting plate 702 to move downward synchronously. When the protrusions 705... When the first filter screen 1301 is pushed to move when it abuts against the side wall of the sliding plate 704, the third spring 303 is compressed. When the protrusion 705 passes the side wall of the sliding plate 704, the first filter screen 1301 can move and reset under the action of the third spring 303. This process is repeated so that when the crushing plate 19 crushes the seaweed, the first filter screen 1301 can move back and forth, making the crushing efficiency higher and the effect better, thus making the filtrate more complete, avoiding waste, and ensuring the extraction efficiency and effect of seaweed extract.

[0042] The support mechanism includes a support plate 801 fixedly connected to the side wall of the filtrate tank 102. Two symmetrically arranged third T-shaped guide rods 802 are inserted into the side wall of the support plate 801. A fifth spring 806 is sleeved on the side wall of each third T-shaped guide rod 802. A second support block 803 is fixedly connected to one end of each third T-shaped guide rod 802. The second support block 803 includes a third inclined surface 804 and a support surface 805. A fixing plate 807 is fixedly connected to the top of the second support block 803. An inclined plate 808 is fixedly connected to the top of the fixing plate 807. The L-shaped plate 701 has an L-shaped first push plate 809 fixedly connected to its side wall. When the first moving plate 17 moves downward, the L-shaped plate 701 drives the first push plate 809 to move downward synchronously, so that the lower end of the first push plate 809 abuts against the inclined plate 808, thereby pushing the second support block 803 to move. At the same time, the fifth spring 806 is compressed, so that the third inclined surface 804 slides on the side wall of the sliding plate 704 and slides the support surface 805 to the bottom of the sliding plate 704 to support the first filter screen 1301.

[0043] The leveling mechanism includes a strip-shaped opening 901 on the side wall of the filtrate tank 102, and a second movable plate 902 is inserted into the strip-shaped opening 901. A scraper 903 is fixedly connected to the side wall of the second movable plate 902, and two symmetrically arranged fixing blocks 904 are fixedly connected to the top of the second movable plate 902. A fourth T-shaped guide rod 905 is inserted into the side wall of the fixing block 904, and one end of the fourth T-shaped guide rod 905 is fixed to the side wall of the filtrate tank 102. A sixth spring 906 is sleeved on the side wall of the fourth T-shaped guide rod 905. Furthermore, the movement of the second moving plate 902 is driven by the third pushing mechanism. Before crushing, the second moving plate 902 and the scraper 903 are moved by the third pushing mechanism. At the same time, the sixth spring 906 is compressed. When the second moving plate 902 passes the second pushing plate 1002, the second moving plate 902 and the scraper 903 can move and reset under the action of the sixth spring 906. This allows the seaweed on the first filter screen 1301 to be scraped flat before crushing, ensuring the efficiency and effect of crushing.

[0044] The third pushing mechanism includes a second connecting plate 1001 fixedly connected to the side wall of the L-shaped plate 701. A second pushing plate 1002 is fixedly connected to the side wall of the second connecting plate 1001, and the second pushing plate 1002 includes two symmetrically arranged fourth inclined surfaces 1003. Before rolling, when the L-shaped plate 701 moves downward, the second pushing plate 1002 moves downward synchronously through the second connecting plate 1001. When the lower fourth inclined surface 1003 abuts against the side wall of the second moving plate 902, it pushes the second moving plate 902 and the scraper 903 to move.

[0045] Working principle: During operation, firstly, during extraction, the seaweed crushed by the crushing device 101 is conveyed through the feed pipe 104 to the first filter screen 1301 in the filtrate tank 102. When it is necessary to crush the large pieces of seaweed on the first filter screen 1301, the motor 605 is started. The rotation of the motor 605 drives the rotation of the threaded rod 604, thereby driving the first moving plate 17 to move downward, and driving the crushing plate 19 to move downward through the first spring 20.

[0046] When the L-shaped plate 701 moves downward, the second connecting plate 1001 drives the second pushing plate 1002 to move downward synchronously. When the lower fourth inclined surface 1003 abuts against the side wall of the second moving plate 902, it pushes the second moving plate 902 and the scraper 903 to move. At the same time, the sixth spring 906 is compressed. When the second moving plate 902 passes the second pushing plate 1002, the second moving plate 902 and the scraper 903 can move and reset under the action of the sixth spring 906. This allows the seaweed on the first filter screen 1301 to be scraped flat before crushing, ensuring the efficiency and effect of crushing.

[0047] When the crushing plate 19 comes into contact with the seaweed, the first spring 20 is gradually compressed. At the same time, when the first moving plate 17 moves downward, the L-shaped plate 701 drives the first pushing plate 809 to move downward synchronously, so that the lower end of the first pushing plate 809 comes into contact with the inclined plate 808, thereby pushing the second support block 803 to move. At the same time, the fifth spring 806 is compressed, so that the third inclined surface 804 slides on the side wall of the sliding plate 704 and slides the support surface 805 to the bottom of the sliding plate 704 to support the first filter screen 1301.

[0048] As the L-shaped plate 701 continues to move downward, it drives the first connecting plate 702 to move downward synchronously. When the protrusion 705 abuts against the side wall of the sliding plate 704, it pushes the first filter screen 1301 to move, the rubber block 403 deforms, and at the same time, the third spring 303 is compressed. When the protrusion 705 passes the side wall of the sliding plate 704, the first filter screen 1301 can move and reset under the action of the third spring 303. This process is repeated so that when the crushing plate 19 crushes the seaweed, the first filter screen 1301 can move back and forth, making the crushing efficiency higher and the effect better, thereby making the filtrate more complete, avoiding waste, and thus ensuring the extraction efficiency and effect of seaweed extract.

[0049] When the multi-stage filter 13 needs to be installed, one side of the multi-stage filter 13 is pressed against the first inclined surface 404 and slid on its surface, pushing the rubber block 403 to move closer to the first support block 401. At the same time, the fourth spring 405 is compressed. After the multi-stage filter 13 is inserted into the first slot 11 and the second slot 12, the rubber block 403 extends under the action of the fourth spring 405, and the limiting surface 406 abuts against the side wall of the multi-stage filter 13, which can limit the multi-stage filter 13 and prevent the multi-stage filter 13 from detaching. When the multi-stage filter 13 needs to be disassembled, the second T-shaped guide rod 402 is pulled to retract the rubber block 403, thus facilitating the installation and disassembly of the multi-stage filter 13.

[0050] Furthermore, when the first filter screen 1301 is disassembled, since there is crushed seaweed remaining on the top of the first filter screen 1301, when the first filter screen 1301 comes into contact with the second inclined surface 503 during disassembly, the first filter screen 1301 is pushed downward. At the same time, the second spring 204 is compressed, the telescopic cover 16 retracts, and the first filter screen 1301 slides at the bottom of the second inclined surface 503, ensuring that there is a distance between the first filter screen 1301 and the top of the first slot 11, preventing seaweed from being scraped into the filtrate tank 102, and ensuring the efficiency and effectiveness of cleaning.
