Description

Technical Field

[0001] The present invention relates to the technical field of phytoplankton management, and in particular to an algae collection device based on a magnetic coagulation process. Background Art

[0002] Phytoplankton are tiny organisms that live in water. When conditions are right, they multiply rapidly and cover the water surface, blocking oxygen from the air and sunlight from entering the water. This reduces oxygen levels and transparency, degrading the living environment for other aquatic plants and animals. The long-term use of products containing nutrients like nitrogen and phosphorus, such as pesticides and laundry detergents, increases the amount of nitrogen and phosphorus flowing into water bodies. Consequently, many lakes and water bodies are experiencing severe eutrophication, allowing phytoplankton to proliferate in large numbers.

[0003] Currently, the primary method used to collect floating algae is to use a cyanobacteria magnetic capture vessel. This vessel employs a magnetic microgrid structure to flocculate pollutants such as nitrogen, phosphorus, and cyanobacteria in eutrophic waters. The magnetic flocs are then attracted by the external magnetic field of a permanent magnet device, where they are "captured" and removed, achieving rapid and continuous separation of the algae from the water. This vessel is suitable for the engineering and large-scale removal of eutrophic substances from various water bodies with a certain open surface area and a depth of at least 1.2 meters. However, cyanobacteria magnetic capture vessels are complex in structure, have high investment costs, and are difficult to transport. Currently, they are only used in large water bodies such as Chaohu Lake, Taihu Lake, Dianchi Lake, and a drinking water reservoir in Shenzhen. Summary of the Invention

[0037] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present invention but are not intended to limit the scope of the present invention. Those skilled in the art may combine and associate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples, unless otherwise contradictory.

[0038] Figure 1 The overall structural diagram of the present invention is illustrated. Figure 4 The schematic diagram of the extension direction of the water outlet pipe 18 is shown as an example. Figure 1 and Figure 4 As shown, the algae collection device based on the magnetic coagulation process of this embodiment includes a float 11, a water intake tank 12, a coagulation tank 13, a power assembly, a separation tank 19, a separation assembly, and a collection tank 23. The float 11 can float on the water surface and can be equipped with a propeller to drive the float 11 forward. The water intake tank 12 is located below the float 11. The water intake tank 12 is equipped with a one-way water intake valve 121 for liquid passage. When the pressure inside the water intake tank 12 is lower than the external pressure, the water intake valve 121 opens; otherwise, the water intake valve 121 closes. The coagulation tank 13 is located above the float 11. One end of the coagulation tank 13 is connected to the water intake tank 12 via a water pipe 14. The water pipe 14 is equipped with a one-way water supply valve 141 for liquid passage. When the pressure inside the water intake tank 12 is higher than the pressure inside the water pipe 14, the water supply valve 141 opens; otherwise, the water supply valve 141 closes.

[0039] The power assembly includes a power channel 15, a driver 16, and a first sealing member 17. One end of the power channel 15 communicates with the water intake tank 12, and the other end communicates with the coagulation tank 13. The first sealing member 17 is slidably connected to the power channel 15. The driver 16 is located within the power channel 15 and is used to actuate the first sealing member 17. The other end of the power channel 15 extends into the coagulation tank 13 and is sealed at its distal end. The power channel 15 communicates with the coagulation tank 13 via multiple water outlet pipes 18, which extend in an arc.

[0040] The separation box 19 is located below the coagulation box 13. The bottom of the coagulation box 13 is connected to the separation box 19 via a waterproof valve 131. The top of the coagulation box 13 is connected to the separation box 19 via a magnetic seed tube 20. The magnetic seed tube 20 is equipped with a one-way magnetic seed valve 201 for air flow. When the pressure inside the coagulation box 13 is lower than atmospheric pressure, the magnetic seed valve 201 opens; otherwise, it closes. A water outlet valve 25 is located at the bottom of the separation box 19, allowing liquid and gas to pass through. The separation assembly is located within the separation box 19 and includes a separation shaft 21 and an electromagnetic element 22. The separation shaft 21 is hollow and rotatably connected to the separation box 19. The separation shaft 21 is driven by a first motor. The electromagnetic element 22 is located within the separation shaft 21 and intermittently generates a magnetic field. The separation assembly is used to separate water, algae, and magnetic seeds. A collection box 23 is connected to the separation box 19 and is used to collect algae.

[0041] When the water intake valve 121 and the water supply valve 141 are both closed, the water intake tank 12 and the power channel 15 form a first closed space; when the water supply valve 141, the waterproof valve 131 and the magnetic seed valve 201 are all closed, the coagulation tank 13 and the power channel 15 form a second closed space.

[0042] By providing a power assembly to regulate the pressure in the water intake tank 12 and the coagulation tank 13, when the driver 16 drives the first seal 17 to slide, the pressure in the water intake tank 12 and the coagulation tank 13 changes accordingly. Specifically, when the first seal 17 moves away from the water intake tank 12, the pressure in the water intake tank 12 decreases, while the pressure in the coagulation tank 13 increases, and vice versa. By providing a one-way water intake valve 121 and a one-way water delivery valve 141, when the pressure in the water intake tank 12 decreases, the water intake valve 121 opens and the water delivery valve 141 closes, increasing the amount of liquid in the water intake tank 12. Conversely, the liquid in the water intake tank 12 enters the water delivery pipe 14 and further flows to the coagulation tank 13, completing the water intake process. By providing a one-way magnetic seed valve 201, when the pressure in the coagulation tank 13 decreases, the magnetic seeds in the separation box 19 can enter the coagulation tank 13 through the magnetic seed tube 20, completing the dosing process. By providing an arc-shaped outlet pipe 18, when liquid enters the coagulation tank 13, it also enters the power channel 15 through the outlet pipe 18. When the first seal 17 approaches the coagulation tank 13, the liquid in the power channel 15 flows out through the arc-shaped outlet pipe 18, disturbing the liquid in the coagulation tank 13 and completing the mixing process. A separation box 19 and a separation assembly are provided below the coagulation tank 13 to separate water, algae, and magnetic seeds. When the liquid and magnetic flocculants in the coagulation tank 13 enter the separation box 19 through the waterproof valve 131, the electromagnetic element 22 generates a magnetic field, attracting the magnetic flocculants to the separation shaft 21, and the liquid flows out through the outlet valve 25. When the separation shaft 21 rotates rapidly, the algae leave the separation shaft 21 under the action of centrifugal force and enter the collection box 23. When the magnetic field of the electromagnetic element 22 disappears, the magnetic seeds leave the separation shaft 21 and enter the coagulation tank 13 through the magnetic seed valve 201. The present invention completes the processes of water intake, drug addition, stirring, separation, algae collection and magnetic seed recovery through the linkage between various components, and has the advantages of compact structure, low cost, wide application scenarios and low transportation cost.

[0043] According to an embodiment of the present invention, Figure 4 As shown, the outlet pipe 18 extends clockwise or counterclockwise when projected on the bottom of the coagulation tank 13; multiple outlet pipes 18 are evenly distributed along the circumference of the power channel 15. When the liquid flows out of the outlet pipe 18, a vortex can be formed in the coagulation tank 13 to achieve stirring of the liquid.

[0044] According to an embodiment of the present invention, the water intake valve 121 includes a grating 1211 and a water intake member. The grating 1211 is provided with multiple through-holes and is connected to the water intake tank 12. Liquid can enter the water intake tank 12 through the grating 1211. The grating 1211 also prevents impurities such as plastic waste and branches in the water from entering the water intake tank 12. The middle portion of the water intake member penetrates the grating 1211 and is slidably connected to the grating 1211. The upper portion of the water intake member can cover the grating 1211 when projected onto the grating 1211, and the lower portion of the water intake member can partially cover the grating 1211 when projected onto the grating 1211. When the pressure in the water intake tank 12 decreases, the water intake member slides upward, allowing liquid to enter the water intake tank 12. When the pressure in the water intake tank 12 increases, the water intake member slides downward, and the upper portion of the water intake member completely covers the grating 1211, preventing liquid from entering the water intake tank 12.

[0045] According to an embodiment of the present invention, Figure 3 yes Figure 1 The enlarged view of point B in the figure is as follows: Figure 3 As shown, water delivery valve 141 includes a first water pipe 1411, a second water pipe 1412, and a first slider 1413. First water pipe 1411 and second water pipe 1412 are adjacently arranged. One end of first water pipe 1411 is connected to water intake tank 12, and the other end is sealed. One end of second water pipe 1412 is connected to water delivery pipe 14, and the other end is sealed. First water pipe 1411 and second water pipe 1412 are connected through first water delivery port 1414 and second water delivery port 1415. First water delivery port 1414 is closer to water intake tank 12 than second water delivery port 1415. Liquid in water intake tank 12 can enter water delivery pipe 14 through first water pipe 1411, first water delivery port 1414 or second water delivery port 1415, and second water pipe 1412 in sequence. The first slider 1413 is disposed within the first water pipe 1411. It is in sealed sliding connection with the first water pipe 1411 and is connected to one sealed end of the first water pipe 1411 via a connecting rope. When the pressure in the water intake tank 12 decreases, the first slider 1413 approaches the water intake tank 12. When the connecting rope is stretched, the first slider 1413 is positioned between the first water transfer port 1414 and the water intake tank 12, preventing liquid in the water transfer pipe 14 from entering the water intake tank 12. When the pressure in the water intake tank 12 increases, the first slider 1413 moves away from the water intake tank 12, allowing liquid in the first water pipe 1411 to enter the second water pipe 1412 through the second water transfer port 1415. When the connecting rope is retracted, the first water transfer port 1414 is positioned between the first slider 1413 and the water intake tank 12, allowing liquid in the water intake tank 12 to enter the water transfer pipe 14 through the first water transfer port 1414.

[0046] According to an embodiment of the present invention, Figure 2 yes Figure 1 The enlarged view of point A in the middle is as follows: Figure 2As shown, the magnetic seed valve 201 includes a cover plate 2011 and a block 2012. The cover plate 2011 is closer to the coagulation tank 13 than the block 2012. One end of the cover plate 2011 is hingedly connected to the magnetic seed tube 20, and the block 2012 is used to abut the cover plate 2011. When the cover plate 2011 abuts the block 2012, the cover plate 2011 seals the magnetic seed tube 20. When the pressure in the coagulation tank 13 decreases, the cover plate 2011 is unscrewed, allowing the magnetic seed to enter the coagulation tank 13 through the magnetic seed tube 20. When the pressure in the coagulation tank 13 increases, the cover plate 2011 is abutted by the block 2012, and the magnetic seed tube 20 is sealed.

[0047] According to an embodiment of the present invention, Figure 1 As shown, the power channel 15 is connected to the top of the water intake tank 12 to prevent the liquid in the water intake tank 12 from entering the power channel 15. The first sealing member 17 is sealed and slidably connected to the power channel 15 to maintain the pressure difference on both sides of the first sealing member 17.

[0048] According to an embodiment of the present invention, a second seal 24 is further provided in the power channel 15, the second seal 24 is provided with a slide groove, a slide rail 241 is provided in the power channel 15, and the slide groove cooperates with the slide rail 241; the second seal 24 and the power channel 15 are sealed and slidably cooperated; the power channel 15 between the first seal 17 and the second seal 24 forms a third sealed space 242, and the driving member 16 is arranged in the third sealed space 242 to prevent the liquid in the water intake tank 12 or the coagulation tank 13 from affecting the service life of the driving member 16.

[0049] According to an embodiment of the present invention, the electromagnetic member 22 is an electromagnet, which is rotatably connected to the separation shaft 21. When the separation shaft 21 rotates, the electromagnet is fixed relative to the separation box 19.

[0050] According to an embodiment of the present invention, the bottom surface of separation tank 19 is inclined, and collection tank 23 is located below separation tank 19 and connected to separation tank 19 via separation valve 231. Separation valve 231 is preferably located at the lowest point of separation tank 19 to facilitate the entry of algae sludge in separation tank 19 into collection tank 23. The sludge and residual magnetic seeds in collection tank 23 can be brought ashore for further processing.

[0051] According to an embodiment of the present invention, the bottom of the coagulation box 13 is in an inverted cone shape, which facilitates the liquid and magnetic flocculants in the coagulation box 13 to enter the separation box 19 .

[0052] The working principle of the present invention is as follows: First, a magnetic seed is placed in the separation tank 19, and then the device is slowly placed into a small body of water where phytoplankton grows. The liquid enters the water intake tank 12 and the water delivery pipe 14 through the water intake valve 121 and the water delivery valve 141. The driving member 16 drives the first sealing member 17 to reciprocate, and the second sealing member 24 also reciprocates. When the first sealing member 17 moves away from the water intake tank 12, the water intake valve 121 opens and the water delivery valve 141 closes, and the liquid in the water intake tank 12 increases. When the first sealing member 17 approaches the water intake tank 12, the water intake valve 121 closes and the water delivery valve 141 opens, and the liquid in the water intake tank 12 enters the water delivery pipe 14 and further flows to the coagulation tank 13 and the power channel 15. At the same time, the waterproof valve 131 closes, the magnetic seed valve 201 opens, and the water outlet valve 25 opens, and the magnetic seed in the separation tank 19 enters the coagulation tank 13 through the magnetic seed pipe 20. When the first seal 17 again moves away from the water intake tank 12, the liquid in the power channel 15 flows out through the curved outlet pipe 18, forming a vortex in the coagulation tank 13. The magnetic seed and the phytoplankton form magnetic flocs. The watertight valve 131 opens, the separation valve 231 closes, and the liquid and magnetic flocs in the coagulation tank 13 enter the separation tank 19. The electromagnet generates a magnetic field, attracting the magnetic flocs to the separation shaft 21, and the liquid flows out through the outlet valve 25. The watertight valve 131 closes, the separation valve 231 opens, and the separation shaft 21 rotates rapidly. The algae are separated from the separation shaft 21 by centrifugal force and enter the collection tank 23. When the magnetic field of the electromagnet disappears, the magnetic seed leaves the separation shaft 21 under the action of centrifugal force and enters the coagulation tank 13 through the magnetic seed valve 201. This cycle repeats, completing the collection of phytoplankton in the water.
