Description

Technical Field

[0001] The present invention relates to the field of algae control devices, and in particular to a pressurized algae control device and a pressurized algae control method thereof. Background Art

[0002] The pressurizing equipment of existing pressurized algae control ships is located on the deck of the cabin. The blue algae on the water surface needs to be pumped into the pressurized algae control device on the deck by a water pump, and then the sucked blue algae is pressurized. By pressurizing the blue algae to 0.7Mpa, the air bags inside the blue algae rupture. The blue algae that lose the buoyancy of the air bags can no longer float on the water surface and grow, but sink to the bottom of the water and die.

[0003] However, cyanobacteria tend to gather near the coast and in shallow bays. When exposed to light, the air sacs in the cyanobacteria cells will recover to a certain extent, and the cyanobacteria will float again after the air sacs recover. This causes the cyanobacteria to grow again after a period of time after being pressurized.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a pressurized algae control device and a pressurized algae control method thereof, so as to solve the problem in the prior art that when cyanobacteria are affected by sunlight, the air sacs in the cyanobacterial cells will recover to a certain extent, causing the cyanobacteria to float again; resulting in the cyanobacteria being able to revive and continue to grow after pressurized treatment.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A pressurized algae control device;

[0008] It comprises: an algae inlet mechanism, a pressurizing chamber, a separation chamber and a stirring chamber which are interconnected along the flow direction of the blue algae; a reflux channel is arranged on the separation chamber; the reflux channel is connected to the pressurizing chamber;

[0009] An extraction device is rotatably arranged in the algae-entering mechanism; the extraction device extracts the blue algae from the algae-entering mechanism and flows them into the pressurized chamber;

[0010] The pressurized chamber is provided with a detection mechanism for detecting the pressure in the pressurized chamber; the detection mechanism controls the opening and closing of the inlet and outlet of the pressurized chamber;

[0011] An impeller is rotatably arranged in the separation chamber; the impeller drives the blue algae in the separation chamber to flow, and the blue algae containing the air sacs flows to a position of the separation chamber close to the reflux channel;

[0012] A stirring blade is rotatably arranged in the stirring chamber; the stirring blade beats, stirs and squeezes the algae particles in the blue algae slurry.

[0013] A further technical solution is that it also includes a boost pump and a pressure relief valve; the boost pump and the pressure relief valve are arranged on the pressurized chamber.

[0014] A further technical solution is that the algae-introducing mechanism comprises: a collecting port floatingly placed on the river surface, an elastic device for pushing the collecting port, and a collecting chamber arranged at the bottom of the hull;

[0015] Among them, the collecting port is movably connected to the hull; the elastic device forms pressure on the collecting port relative to the buoyancy of the river surface; the extraction device is rotatably arranged in the collecting chamber; the collecting chamber is respectively connected to the collecting port and the pressurized chamber.

[0016] A further technical solution is that a first power device is arranged outside the separation chamber; a second gear is arranged on the impeller and on the driving end of the first power device; the second gears are meshed with each other; a notch is opened on the separation chamber near the reflux channel; a door panel is swingably arranged at the notch position; and the door panel opens and closes the notch.

[0017] A further technical solution is that the impeller includes an axle, a disc and blades arranged in parallel on the disc; the blades extend from the middle position of the disc to the edge position of the disc; the blades bend in the rotation direction of the disc; the disc is arranged on the axle; and the axle is rotatably arranged in the separation chamber.

[0018] A further technical solution is that the stirring blade comprises a stirring shaft rotatably arranged in the stirring chamber, a stirring body arranged around the stirring shaft, a collecting tank for collecting algae particles in the blue algae slurry, and a sliding member for squeezing the algae particles in the collecting tank;

[0019] Wherein, the collecting tank is arranged on the stirring body; and the sliding member is slidably connected to the stirring body.

[0020] A pressurized algae control method of a pressurized algae control device comprises the following steps:

[0021] Blue algae collection steps: the elastic device pushes the collection port so that the collection port floats along the river surface; the blue algae enter the collection chamber through the collection port; the extraction device rotates to send the blue algae into the pressure chamber;

[0022] Pressurization and rupture steps: When the blue algae enter the pressurization chamber, the pressure relief valve discharges the air in the pressurization chamber; the booster pump injects water into the pressurization chamber so that the pressure in the pressurization chamber reaches 0.7Mpa; the air sacs in the blue algae rupture;

[0023] Separation and recovery steps: the cyanobacteria in the pressurized chamber enter the separation chamber; the impeller rotates to drive the cyanobacteria to flow in the pressurized chamber; the cyanobacteria whose airbags are not broken flow to the edge of the pressurized chamber; at this time, the door panel is opened, and the cyanobacteria whose airbags are not broken flow into the pressurized chamber through the gap;

[0024] Stirring and squeezing steps: the blue algae in the separation chamber enters the stirring chamber; the stirring blade rotates, and when the stirring body moves out the blue algae, the algae particles in the blue algae slurry remain in the collecting tank; when the stirring body moves into the blue algae, the stirring body beats and stirs the blue algae liquid surface, and the algae particles in the blue algae slurry complete the first squeezing; when the stirring body is placed on the blue algae, the sliding part squeezes and pushes out the algae particles in the blue algae slurry to complete the second squeezing, and the blue algae accumulates in the collecting tank again;

[0025] Discharge and sedimentation steps: After the algae particles in the blue algae slurry are squeezed into blocks, they are discharged from the stirring chamber and then precipitated.

[0026] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) When the pressure in the pressurized chamber reaches 0.7 MPa, most of the air sacs in the cyanobacteria rupture, but the air sacs in some cyanobacterial cells remain intact; the cyanobacteria with ruptured air sacs sink, while the cyanobacteria with intact air sacs float; driven by the impeller, the cyanobacteria with intact air sacs flow into the pressurized chamber through the reflux channel;

[0027] When the stirring blade rotates in the stirring chamber, the stirring blade will repeatedly beat and stir the liquid surface of the blue algae; when the stirring blade rotates along the blue algae, the blue algae accumulate on the stirring blade; when the stirring blade rotates along the air, the clear water in the blue algae is discharged, and the algae particles in the blue algae slurry are retained; when the stirring blade contacts the liquid surface of the blue algae, the stirring blade beats and stirs the algae particles in the blue algae slurry, and the algae particles in the blue algae slurry are pressed and squeezed into blocks;

[0028] The blue algae are discharged from the separation chamber, and the blocky algae particles sink along the river (lake) water. The blocky algae particles are affected by light, and the air bags in the algae particles on their surface will recover to a certain extent. Since the blocky algae particles have high density and heavy weight, they sink to the bottom of the water and do not float up. The algae particles gradually die, and the blue algae will not recover.

[0029] (2) When the stirring body is placed in the blue algae, more algae particles can be attached to the first tooth shape; when the sliding member slides along the collecting groove, the second tooth shape slides along the first tooth shape, so that the sliding member slides smoothly and prevents the sliding member from falling out of the collecting groove; the first tooth shape has a certain grasping ability for the algae particles, and when the sliding member squeezes the algae particles, the algae particles will not fall out of the first tooth shape, and the algae particles can be completely flattened into shape.

[0030] (3) Since water is injected into the pressurized chamber instead of air, due to the incompressibility of water, only a small amount of water needs to be injected into the pressurized chamber to make the pressure in the pressurized chamber reach 0.7 MPa; when the cyanobacteria are discharged in the discharge and sedimentation step, no bubbles are precipitated, thereby preventing the algae particles in the cyanobacteria slurry from floating up.

[0031] (4) The stirring blade rotates. When the stirring body moves out of the cyanobacteria, the cyanobacteria accumulate in the collection tank. When the stirring body moves in the vertical direction, the clear water in the cyanobacteria flows out of the collection tank, and the algae particles in the cyanobacteria slurry remain in the collection tank. When the stirring body moves into the cyanobacteria, the stirring body beats and stirs the cyanobacteria liquid surface, and the stirring body and the cyanobacteria liquid surface squeeze the algae particles in the cyanobacteria slurry, and the algae particles in the cyanobacteria slurry complete the first squeezing.

[0032] When the stirring body is placed on the blue algae, the sliding member moves along the collecting tank, the sliding member squeezes and pushes out the algae particles in the blue algae slurry, and the algae particles in the blue algae slurry complete the second squeezing, and the blue algae accumulate in the collecting tank again;

[0033] The algae particles in the blue algae slurry are squeezed twice to form block-shaped algae particles; the stirring blades rotate back and forth continuously, and the number of block-shaped algae particles in the blue algae gradually increases, and are discharged from the stirring chamber and then precipitated.

[0044] First embodiment:

[0045] Figure 1 A structural schematic diagram showing the installation position of the pressurized algae control device according to the first embodiment of the present invention. Figure 2 The figure shows a schematic structural diagram of the algae introducing mechanism according to the first embodiment of the present invention. Figure 3 A schematic diagram of the top view of the extraction device according to the first embodiment of the present invention is shown. Figure 4 The schematic diagram of the structure of the separation chamber and the impeller of the first embodiment of the present invention is shown. Figure 1-Figure 4 As shown, the present invention discloses a pressurized algae control device.

[0046] The pressurized algae control device comprises: an algae inlet mechanism 1, a pressurized chamber 3, a separation chamber 4 and a stirring chamber 5 which are interconnected along the flow direction of the blue algae. A reflux channel 6 is arranged on the separation chamber 4. The reflux channel 6 is connected to the pressurized chamber 3.

[0047] The inlets of the algae-introducing mechanism 1 are respectively located at the head and the side of the hull. When the boat starts, the blue algae near the hull flow into the algae-introducing mechanism 1 from different directions.

[0048] An extraction device 2 is rotatably arranged in the algae-entering mechanism 1. The extraction device 2 extracts the blue algae from the algae-entering mechanism 1 and flows into the pressurized chamber 3.

[0049] The blue algae flow in from different directions, and the amount of blue algae entering the pressurized chamber 3 can be adjusted by adjusting the power of the extraction device 2 .

[0050] The pressurized chamber 3 is provided with a detection mechanism 9 for detecting the pressure in the pressurized chamber 3. The detection mechanism 9 controls the opening and closing of the inlet and outlet of the pressurized chamber 3.

[0051] Exemplarily, the detection mechanism 9 is a pressure sensor. Exemplarily, the pressurizing chamber 3 is divided into two groups. The pressurizing chambers 3 work alternately to transport the blue algae into the separation chamber 4.

[0052] When blue algae flow into the pressurized chamber 3, the inlet of the pressurized chamber 3 is opened and the outlet of the pressurized chamber 3 is closed. When the pressurized chamber 3 is pressurized, the inlet and outlet of the pressurized chamber 3 are closed at the same time. When blue algae flow out of the pressurized chamber 3, the outlet of the pressurized chamber 3 is opened and the inlet of the pressurized chamber 3 is closed.

[0053] The opening and closing timing of the inlet and outlet of the pressurized chamber 3 is determined by the detection mechanism 9. When the pressure in the pressurized chamber 3 reaches 0.7 MPa, most of the air sacs in the cyanobacteria are ruptured, but there are still some air sacs in the cyanobacterial cells that have not been ruptured.

[0054] An impeller 7 is rotatably arranged in the separation chamber 4. The impeller 7 drives the cyanobacteria in the separation chamber 4 to flow, and the cyanobacteria containing air sacs flow to the position of the separation chamber 4 near the reflux channel 6. Exemplarily, the cyanobacteria containing air sacs are cyanobacterial cells whose air sacs are not collapsed after being pressurized. The inlet of the reflux channel 6 is connected to the upper end of the separation chamber 4. The outlet of the reflux channel 6 is connected to the pressurization chamber 3.

[0055] The blue algae with ruptured airbags sink, and the blue algae with unruptured airbags float. Driven by the impeller 7, the flow path height of the blue algae with unruptured airbags is greater than the flow path height of the blue algae with ruptured airbags. When the inlet of the reflux channel 6 is opened, the blue algae with unruptured airbags flow into the pressurized chamber 3 through the reflux channel 6.

[0056] After the pressurized algae control device has been working for a long time, some blue algae with unbroken airbags will remain in the pressurized chamber 3. Such blue algae cannot be broken by the airbags after repeated 0.7Mpa pressure. Therefore, the pressurized chamber 3 needs to be cleaned regularly.

[0057] A stirring blade 8 is rotatably arranged in the stirring chamber 5. The stirring blade 8 beats, stirs and accumulates algae particles in the blue algae slurry.

[0058] When the blue algae in the separation chamber 4 enters the stirring chamber 5, the stirring chamber 5 is not filled. When the stirring blade 8 rotates in the stirring chamber 5, the stirring blade 8 repeatedly beats and stirs the liquid surface of the blue algae. When the stirring blade 8 rotates along the blue algae, the blue algae accumulate on the stirring blade 8. When the stirring blade 8 rotates along the air, the clear water in the blue algae is discharged, and the algae particles in the blue algae slurry are retained. When the stirring blade 8 contacts the liquid surface of the blue algae, the stirring blade 8 beats and stirs the algae particles in the blue algae slurry, and the algae particles in the blue algae slurry are subjected to pressure and squeezed into blocks.

[0059] The blue algae are discharged from the separation chamber 4, and the block-shaped algae particles sink along the river water. The block-shaped algae particles are affected by light, and the air bags in the algae particles on the surface will recover to a certain extent. Since the block-shaped algae particles are heavy, they will not float up, and the algae particles will gradually die, and the blue algae will not recover.

[0060] The algae introducing mechanism 1 comprises: a collecting port 11 floatingly placed on the river surface, an elastic device 12 for pushing the collecting port 11, and a collecting chamber 13 arranged at the bottom of the hull.

[0061] The collecting port 11 is movably connected to the hull. The elastic device 12 forms pressure on the collecting port 11 relative to the buoyancy of the river surface. The extracting device 2 is rotatably arranged in the collecting chamber 13. The collecting chamber 13 is connected to the collecting port 11 and the pressurizing chamber 3 respectively.

[0062] Exemplarily, the elastic device 12 is a spring. The collecting port 11 is formed with an upward extension. The extension passes through the hull, and the elastic device 12 is sleeved on the extension. The elastic device 12 forms a downward pressure on the collecting port 11, so that the collecting port 11 always floats on the river surface.

[0063] Floats are arranged on both sides of the collection port 11, and the floats form buoyancy on the collection port 11. The pressure of the elastic device 12 on the collection port 11 is greater than the buoyancy of the collection port 11. The lower part of the collection port 11 is immersed in the cyanobacteria liquid surface, and the upper part of the collection port 11 is higher than the cyanobacteria liquid surface. The cyanobacteria on the liquid surface are always within the collection range of the collection port 11.

[0064] The height of the collecting chamber 13 is lower than the height of the inlet of the collecting port 11 . Due to the height difference, the blue algae can quickly flow into the collecting chamber 13 after flowing into the inlet of the collecting port 11 .

[0065] The extraction device 2 includes a rotating wheel 21 and a second power device 22 for driving the rotating wheel 21 to rotate. A first gear 23 is arranged on the rotating wheel 21. The first gear 23 is rotatably arranged on the collecting chamber 13. The first gears 23 are meshed with each other. The second power device 22 drives the rotating wheel 21 to rotate, and drives the adjacent rotating wheel 21 to rotate through the first gear 23, and the rotating wheel 21 transports the blue algae to the pressurizing chamber 3.

[0066] The pressurized algae control device further includes a booster pump 91 and a pressure relief valve 92. The booster pump 91 and the pressure relief valve 92 are arranged on the pressurized chamber 3.

[0067] The extraction device 2 is unable to raise the pressure in the pressurized chamber 3 to 0.7 MPa. The water at the bottom of the hull is extracted by the booster pump 91 and the water is injected into the pressurized chamber 3 to reach 0.7 MPa.

[0068] Figure 5 The left side structural diagram of the door panel position of the first embodiment of the present invention is shown. Figure 1-Figure 5 As shown:

[0069] A first power device 41 is arranged outside the separation chamber 4. Exemplarily, the first power device 41 is a motor. A second gear 42 is arranged on the impeller 7 and at the driving end of the first power device 41. The second gears 42 mesh with each other. The first power device 41 drives the impeller 7 to rotate through the second gear 42.

[0070] A notch 43 is provided on the separation chamber 4 near the reflux channel 6 . A door plate 44 is swingably provided at the notch 43 . The door plate 44 opens and closes the notch 43 .

[0071] The upper surface of the separation chamber 4 is formed with a top surface with a height difference, and the notch 43 is located at the height difference position of the top surface. The notch 43 is set obliquely. The door plate 44 is set at the position of the notch 43 in an inclined swing. The height difference of the top surface is small, so that the blue algae flows along the separation chamber 4, and the flow process is relatively smooth when transitioning from one side of the top surface to the other side of the top surface.

[0072] A third power device 45 is installed outside the separation chamber 4. For example, the third power device 45 is a motor. The third power device 45 drives the door plate 44 to swing to close or open the gap 43.

[0073] The driving end of the third power device 45 is connected to the door panel 44 through the third gear 46. The third gear 46 is respectively arranged at the swing position of the door panel 44 and the driving end of the third power device 45. Exemplarily, the third gear 46 at the swing position of the door panel 44 is a sector gear. The third power device 45 drives the third gear 46 to rotate, and the third gears 46 mesh with each other to complete the power transmission, driving the third gear 46 on the door panel 44 and the door panel 44 to swing, and the door panel 44 closes or opens the notch 43.

[0074] Driven by the impeller 7, the blue algae whose airbags are not broken flow along the top surface, and at this time, the third power device 45 drives the door plate 44 to open the notch 43. The blue algae whose airbags are not broken flow back into the pressurized chamber 3 through the reflux channel 6. The blue algae remaining in the separation chamber 4 are the blue algae whose airbags are broken.

[0075] The speed of the impeller 7 is related to the proportion of cyanobacteria with unbroken air capsules in the cyanobacteria. The speed of the impeller 7 is set to X. When the proportion of cyanobacteria with unbroken air capsules / cyanobacteria is less than 1.5%, the speed of the impeller 7 is X. When the proportion of cyanobacteria with unbroken air capsules / cyanobacteria is between 1.5% and 4%, the speed of the impeller 7 is 1.05 to 1.2*X.

[0076] The impeller 7 includes a wheel shaft 73, a wheel disc 71 and blades 72 arranged in parallel on the wheel disc 71. The wheel shaft 73 is arranged to rotate in the separation chamber 4 in the left-right direction. The wheel disc 71 is arranged on the wheel shaft 73 in the vertical direction.

[0077] A plurality of blades 72 are arranged on the wheel disc 71. The blades 72 extend from the middle position of the wheel disc 71 to the edge position of the wheel disc 71, and the blades 72 bend toward the rotation direction of the wheel disc 71 during the extension process.

[0078] When the wheel disc 71 rotates, the blades 72 drive the blue algae to flow. The blue algae form a vortex near the wheel disc 71. Driven by the vortex, the flow path height of the blue algae whose airbags are not broken is greater than the flow path height of the blue algae whose airbags are broken. The blue algae whose airbags are not broken are closer to the gap 43.

[0079] Figure 6 The schematic diagram of the structure of the stirring chamber and stirring blades of the first embodiment of the present invention is shown. Figure 7 The schematic diagram shows the cross-sectional position of the stirring body when the sliding member 84 of the first embodiment of the present invention slides along the collecting tank. Figure 8 The schematic diagram of the structure of the cross-section of the stirring body when the sliding member 84 of the first embodiment of the present invention slides along the stirring body is shown. Figure 1-Figure 8 As shown:

[0080] The stirring blade 8 includes a stirring shaft 81 rotatably arranged in the stirring chamber 5 in the left and right direction, a stirring body 82 arranged around the stirring shaft 81 , a collecting groove 83 for collecting algae particles in the blue algae slurry, and a sliding member 84 for squeezing the algae particles in the collecting groove 83 .

[0081] The collecting tank 83 is disposed on the stirring body 82 along the stirring body 82 . The sliding member 84 is slidably connected to the stirring body 82 .

[0082] The first tooth shape 831 is obliquely provided on both sides of the collecting groove 83. The second tooth shape 841 is obliquely provided on both sides of the sliding member 84. The first tooth shape 831 and the second tooth shape 841 are meshed with each other.

[0083] When the stirring body 82 is placed in the blue algae, more algae particles can be attached to the first tooth shape 831. When the sliding member 84 slides along the collecting groove 83, the second tooth shape 841 slides along the first tooth shape 831, so that the sliding member 84 slides smoothly and prevents the sliding member 84 from escaping from the collecting groove 83. The first tooth shape 831 has a certain grasping ability for the algae particles. When the sliding member 84 squeezes the algae particles, the algae particles will not detach from the first tooth shape 831, and the algae particles can be completely flattened into shape.

[0084] A guide groove 821 is formed on both sides of the stirring body 82. A bracket 842 is formed on both sides of the sliding member 84. The bracket 842 extends and inserts into the guide groove 821. Exemplarily, the guide groove 821 is annular.

[0085] The stirring shaft 81 drives the stirring body 82 to rotate during the rotation process. When the stirring body 82 rotates to a horizontal state, the stirring body 82 approaches the blue algae liquid surface and gradually enters the blue algae. The stirring body 82 continues to rotate, and the stirring body 82 gradually moves to a vertical state in the blue algae. The sliding member 84 squeezes the algae particles in the collecting tank 83 and pushes them out of the collecting tank 83. When the stirring body 82 continues to rotate to a horizontal state, the stirring body 82 approaches the blue algae liquid surface and gradually moves out of the blue algae. When the stirring body 82 continues to rotate to a vertical state, the clean water in the algae particles in the collecting tank 83 is discharged, and this reciprocating cycle is repeated.

[0086] Furthermore, the stirring shaft 81 rotates to drive the stirring body 82 to immerse in the blue algae. When the stirring body 82 rotates along the blue algae, the blue algae accumulate in the collecting tank 83. After the stirring body 82 rotates and separates from the blue algae, the stirring body 82 gradually rotates to a vertical state, and the clean water in the blue algae flows downward and is discharged, and algae particles remain in the collecting tank 83. The sliding member 84 has a certain weight. The bracket 842 slides along the guide groove 821 under the action of the gravity of the sliding member 84, driving the sliding member 84 to slide downward along the stirring body 82, and the sliding member 84 slides to the end of the stirring body 82 close to the stirring shaft 81. When the stirring body 82 continues to rotate and approaches the blue algae liquid surface, the blue algae liquid surface slaps and stirs the algae particles. The bracket 842 slides along the guide groove 821, driving the sliding member 84 to slide along the collecting tank 83, and the sliding member 84 squeezes the algae particles in the collecting tank 83. The sliding member 84 slides to one end of the collecting tank 83 away from the stirring shaft 81 , and the sliding member 84 squeezes the algae particles in the collecting tank 83 and pushes them out of the collecting tank 83 , so that new blue algae accumulate in the collecting tank 83 again.

[0087] The guide groove 821 includes two groups of parallel long sides and short sides connecting the two ends of the long sides, and the long sides and the short sides form a ring. There is a distance between the two groups of long sides, so that when the bracket 842 slides along different long sides, the position of the sliding member 84 is different.

[0088] When the sliding member 84 slides along the collection tank 83, the bracket 842 slides along the long side of one set of guide grooves 821. At this time, the surface of the sliding member 84 contacts the surface of the collection tank 83. During the sliding process, the sliding member 84 can squeeze the algae particles in the collection tank 83 and push them out of the collection tank 83. When the sliding member 84 slides along the stirring body 82, the bracket 842 slides along the long side of another set of guide grooves 821. At this time, the surface of the sliding member 84 does not contact the surface of the collection tank 83, and there is a distance between the two. The clean water in the blue algae in the collection tank 83 is discharged. The bracket 842 completes the switching between the long sides of the two sets of guide grooves 821 through the short sides of the guide grooves 821, so that the sliding member 84 completes the position switching between sliding in the collection tank 83 and sliding on the stirring body 82.

[0089] The blue algae are collected by the stirring body 82 and the algae particles in the blue algae are squeezed into blocks by the sliding member 84. The blue algae in the stirring chamber 5 are discharged into the river, and the block algae particles fall and settle rapidly due to their own weight.

[0090] When the surface of the block algae particles is exposed to sunlight, the ruptured air sacs in the surface algae particles will recover to a certain extent, but it is not enough to drive the entire block algae particles to float, and the block algae particles will still settle at the bottom of the river.

[0091] The stirring blade 8 is driven by the fourth power device 85. The driving end of the fourth power device 85 is connected to the stirring shaft 81. A stirring support 51 is arranged in the stirring chamber 5. The stirring shaft 81 passes through the stirring support 51 and rotates along the stirring support 51.

[0092] The stirring support 51 restricts the stirring shaft 81 in radial direction, so that the stirring blade 8 can rotate stably.

[0093] The rotation speed of the stirring shaft 81 is related to the content of algae particles in the blue algae in the stirring chamber 5 .

[0094] The content of algae particles in the blue algae in the stirring chamber 5 is set to Y, and the corresponding rotation speed of the stirring shaft 81 is E1.

[0095] The content of algae particles in the blue algae in the stirring chamber 5 is at least 50% of Y, and the content of algae particles in the blue algae in the stirring chamber 5 is at most 150% of Y.

[0096] When the content of algae particles in the blue algae in the stirring chamber 5 increases by 10%, the rotation speed of the stirring shaft 81 increases by 5%.

[0097] When the content of algae particles in the blue algae in the stirring chamber 5 decreases by 10%, the rotation speed of the stirring shaft 81 decreases by 3.5%.

[0098] In order to ensure the squeezing effect of the algae particles twice so that the algae particles are compacted, it is necessary to control the amount of algae particles contained in the collecting tank 83. When the content of algae particles in the blue algae in the stirring chamber 5 increases, it is necessary to increase the rotation speed of the stirring shaft 81. When the content of algae particles in the blue algae in the stirring chamber 5 decreases, it is necessary to slow down the rotation speed of the stirring shaft 81. In this way, the amount of algae particles in the collecting tank 83 is controlled to ensure the squeezing effect of the algae particles.

[0099] The rotation speed of the stirring shaft 81, the weight of the slider 84, and the floating rate of the blue algae are related.

[0100] The floating rate of the blue algae in the stirring chamber 5 is set to F, the corresponding rotation speed of the stirring shaft 81 is E2, and the weight of the sliding member 84 is M.

[0101] When the floating rate of the blue algae in the stirring chamber 5 is 1.75-2.5%, the rotation speed of the stirring shaft 81 is E2=(1-0.95)*E1, and the weight M of the sliding member 84 remains unchanged.

[0102] When the floating rate of the blue algae in the stirring chamber 5 is 1.25%<F<1.75%, the rotation speed E2 of the stirring shaft 81 is equal to (1.05~1.15)*E1, and the weight M of the sliding member 84 is increased by 10%.

[0103] When the floating rate of the blue algae in the stirring chamber 5 is relatively large, the algae particles in the blue algae are evenly distributed, and the algae particles can be evenly distributed in the collecting tank 83 .

[0104] When the floating rate of the blue algae in the stirring chamber 5 is low, the algae particles are concentrated at the bottom of the blue algae. By increasing the rotation speed of the stirring shaft 81, the algae particles in the blue algae are stirred up and floated, so that the algae particles are diffused and distributed in the collecting tank 83. At the same time, the sliding member 84 is weighted to increase the strength of the second squeezing, so that the algae particles can be compacted.

[0105] Second embodiment:

[0106] The pressurized algae control method of the pressurized algae control device comprises the following steps:

[0107] Blue algae collection step: The elastic device 12 forms a downward pushing force on the collection port 11, so that the collection port 11 floats along the river surface. The inlet of the collection port 11 will not be higher than the river surface, and the inlet of the collection port 11 will not be completely immersed in the river surface.

[0108] The blue algae enter the collection chamber 13 through the collection port 11. The extraction device 2 rotates to send the blue algae into the pressure chamber 3.

[0109] During the movement of the ship, the blue algae on the river surface naturally flow into the collecting port 11 . However, the inflow of blue algae is relatively small at this time, and more blue algae flow into the pressurizing chamber 3 through the collecting port 11 through the rotation of the extraction device 2 .

[0110] Pressurization and rupture step: When the blue algae enter the pressurization chamber 3, the pressure relief valve 92 discharges the air in the pressurization chamber 3. After the pressurization chamber 3 is filled, the pressure in the pressurization chamber 3 cannot be increased to 0.7Mpa by the extraction device 2. Water is injected into the pressurization chamber 3 by the booster pump 91, so that the pressure in the pressurization chamber 3 reaches 0.7Mpa, and the air sacs in the blue algae are ruptured.

[0111] Since water is injected into the pressurized chamber 3 instead of air, due to the incompressibility of water, only a small amount of water needs to be injected into the pressurized chamber 3 to make the pressure in the pressurized chamber 3 reach 0.7Mpa. When the blue algae are discharged in the discharge and sedimentation step, no bubbles are precipitated, which prevents the algae particles in the blue algae slurry from floating up.

[0112] After the blue algae are subjected to a pressure of 0.7Mpa, most of the air sacs in the algae particles rupture, but a small number of air sacs remain intact. If the algae particles whose air sacs have not ruptured are squeezed into blocks, the buoyancy of the block algae particles will increase, increasing the risk of the block algae particles floating.

[0113] Separation and recovery step: The blue algae in the pressurized chamber 3 enter the separation chamber 4, and the impeller 7 rotates to drive the blue algae to flow in the pressurized chamber 3. The blue algae whose airbags are not broken flow to the edge of the pressurized chamber 3, and the door plate 44 opens, and the blue algae whose airbags are not broken flow into the pressurized chamber 3 through the gap 43.

[0114] The algae particles whose airbags are not broken have a certain buoyancy, and the flow path height of the blue algae whose airbags are not broken is greater than the flow path height of the blue algae whose airbags are broken. The blue algae whose airbags are not broken are close to the top surface of the separation chamber 4. After the door plate 44 is opened, the blue algae whose airbags are not broken enter the reflux channel 6 through the notch 43, and finally flow into the pressurized chamber 3.

[0115] Stirring and squeezing step: the blue algae in the separation chamber 4 enters the stirring chamber 5. The stirring blade 8 rotates, and when the stirring body 82 moves out of the blue algae, the blue algae accumulates in the collecting tank 83. During the vertical movement of the stirring body 82, the clear water in the blue algae flows out of the collecting tank 83, and the algae particles in the blue algae slurry remain in the collecting tank 83. When the stirring body 82 moves into the blue algae, the stirring body 82 beats and stirs the blue algae liquid surface, and the stirring body 82 and the blue algae liquid surface squeeze the algae particles in the blue algae slurry, and the algae particles in the blue algae slurry complete the first squeezing.

[0116] When the stirring body 82 is placed on the blue algae, the sliding member 84 moves along the collecting tank 83, and the sliding member 84 squeezes and pushes out the algae particles in the blue algae slurry, and the algae particles in the blue algae slurry complete the second squeezing. At this time, the blue algae accumulate in the collecting tank 83 again.

[0117] The algae particles in the blue algae slurry are squeezed twice to form block algae particles. In the stirring and squeezing step, the stirring blade 8 rotates back and forth continuously, and the number of block algae particles in the blue algae gradually increases.

[0118] Discharge and sedimentation step: After the algae particles in the blue algae slurry are squeezed into blocks, they are discharged from the stirring chamber 5 and then precipitated.

[0119] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
