DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The following describes an embodiment of the present invention based on its overall structure.

[0037] Example

[0038] See also Figure 1-8 As shown, a method for implementing microalgae carbon fixation technology for carbon dioxide flue gas recovery includes the following steps:

[0039] Step 1: Microalgae cultivation: Microalgae, culture solution and water are fed into the liquid storage tank 1 through the addition port 103. At this time, the carbon dioxide supply system feeds the collected carbon dioxide flue gas into the gas supply tank 2 through the supply pipe and the connecting pipe 201, and then passes through multiple aeration pipes 202 to form small bubbles that dissolve in the water, and the carbon dioxide is fixed by the photosynthesis of the microalgae;

[0040] Step 2: Mixing: Using the rotating assembly 4 in the driving mechanism 3, the storage tank drives the gear ring 1011 to rotate through the rotating driving gear 403, so that the upper shell 101 rotates along the lower shell 104, and the stirring rod 102 ensures that the microalgae are evenly distributed in the liquid storage tank 1 and fully exposed to light and carbon dioxide;

[0041] Step three, separation and replacement, by energizing the electromagnet 5021 in the separation component 5 to generate magnetism, the clamping block 702 of the clamping component 7 is inserted into the clamping groove 704, and the plug-in rod 504 and the threaded rod 502 are clamped and connected. At this time, the dual-axis motor 402 works and can control the rotation of the two threaded rods 502 under the action of the transmission wheel 505, so that the lifting plate 507 drives the upper shell 101 to move upward and separate from the lower shell 104. Then the aeration pipe 202 can be unscrewed from the connecting pipe 201 for replacement and cleaning, and the liquid storage tank 1 can be cleaned at the same time.

[0042] The dual-axis motor 402 and the two electromagnets 5021 in the present application are controlled by an external controller, and an inward-recessed handle is provided on the top of the sealing block for sealing the addition port 103, which makes it convenient for the staff to twist it without hindering the rotation of the upper shell 101. The sealing structure of the discharge pipe 1042 adopts the existing technology, such as the discharge pipe structure in the application number CN202211344280.9.

[0043] See also Figure 2-6 As shown, the liquid storage tank 1 is composed of an upper shell 101 and a lower shell 104. The bottom surface of the upper shell 101 is provided with a first slot 1013, and the top surface of the lower shell 104 is provided with a second slot 1041. The first slot 1013 and the second slot 1041 are plugged into each other. The top surface of the upper shell 101 is provided with an addition port 103. A blocking block is installed in the addition port 103 through a thread and the top is flush with the top surface of the upper shell 101. Stirring rods 102 are symmetrically fixed to the inner top wall of the upper shell 101. The lengths of the two stirring rods 102 are both less than the height of the upper shell 101. A plurality of vertical rods 6 are evenly fixed to the inner bottom wall of the lower shell 104. An annular scraper 60 is fixed to the top of the plurality of vertical rods 6. 1. The cross section of the scraper 601 is inclined. The inclined bottom wall of the scraper 601 contacts and slides with the inner wall of the upper shell 101, and the inclined top wall of the scraper 601 contacts the inner top wall of the upper shell 101. Four support frames 105 are evenly fixed on the lower surface of the lower shell 104. A discharge pipe 1042 is provided on the lower surface of the lower shell 104. The discharge pipe 1042 is located on one side of the air supply box 2. The driving mechanism 3 is composed of a rotating component 4, a separating component 5 and a clamping component 7. The tops of the multiple connecting pipes 201 are all connected to the bottom of the lower shell 104. The multiple aeration pipes 202 are all connected to the connecting pipe 201 by threaded engagement. A light source is also provided on the inner top wall of the upper shell 101.

[0044] An air supply box 2 is provided below the lower shell 104, and the bottom ends of multiple connecting pipes 201 are connected to the top of the air supply box 2. An air injection pipe 203 is connected to the center of the bottom of the air supply box 2. The air injection pipe 203 passes through the protective box 204 and is connected to the supply pipe of the carbon dioxide supply system.

[0045] First, the plug-in rod 504 in the separation component 5 is connected to the threaded rod 502 through the clamping component 7. At this time, the dual-axis motor 402 is started through the controller. The output end of the dual-axis motor 402 drives the connected threaded rod 502 to rotate through the transmission wheel 505, and controls the upper shell 101 to move up and separate from the lower shell 104. At this time, the staff can screw multiple aeration tubes 202 in turn, move along the thread of the inner wall of the connecting tube 201, complete the separation, and then screw the aeration tube 202 to be replaced into the connecting tube 201. Aeration tubes 202 with different apertures can be replaced according to needs. The dual-axis motor 402 is started in the reverse direction to move the upper shell 101 downward until the outer groove wall of the first slot 1013 is inserted into the groove of the second slot 1041, wherein a sealing gasket is provided in the groove for sealing, and the clamping component 7 is reset, and the plug-in rod 504 is separated from the threaded rod 502;

[0046] Then the staff unscrews the blocking block and adds the microalgae, culture solution and water into the liquid storage tank 1 through the addition port 103. Then the dual-axis motor 402 works, and the upper shell 101 rotates along the lower shell 104 through the rotating assembly 4, and drives the stirring rod 102 to stir the water, so that the microalgae are evenly distributed inside the liquid storage tank 1. At this time, the carbon dioxide supply system sends the collected carbon dioxide flue gas into the air supply box 2 through the supply pipe and the connecting pipe 201, and then passes through multiple aeration pipes 202 to form small bubbles that dissolve in the water, and uses the photosynthesis of the microalgae to fix carbon dioxide. Finally, the microalgae and water can be discharged through the discharge pipe 1042;

[0047] Therefore, the present application can be quickly separated and engaged when needed, which is convenient for cleaning the inner wall and maintaining the internal structure; at the same time, the aeration tube 202 can be more conveniently disassembled after separation, so that the aeration tube 202 with different apertures can be replaced according to the mass transfer requirements of carbon dioxide, thereby ensuring the efficiency of carbon dioxide introduction.

[0048] See also Figure 7 and 8 As shown, the clamping assembly 7 includes square grooves 701 symmetrically opened on the outer wall of the plug-in rod 504, and a clamping block 702 is movably installed in each square groove 701. A groove 7021 is symmetrically opened on a side of each clamping block 702 close to the plug-in rod 504, and a return spring 703 is provided in each groove 7021. The two ends of each return spring 703 are respectively fixedly connected to the groove 7021 and the groove wall of the square groove 701, and the groove walls of the two plug-in grooves 5022 are symmetrically opened with clamping grooves 704. Each clamping block 702 matches the clamping groove 704, and each clamping block 702 is made of iron block. The bottom outer walls of the two threaded rods 502 are located at the clamping groove 704 and are fixedly sleeved with an annular electromagnet 5021, and the two electromagnets 5021 are located above the L-shaped frame plate 501.

[0049] The electromagnet 5021 is energized through an external controller to generate magnetism, and the magnetism penetrates the rod wall of the threaded rod 502 to absorb the clamping block 702 located in the plug-in slot 5022. The clamping block 702 is affected by the magnetism and extends out of the square slot 701 and inserts into the clamping slot 704, and stretches the reset spring 703, thereby completing the connection between the threaded rod 502 and the plug-in rod 504; when the connection needs to be canceled, the electromagnet 5021 is powered off and the magnetism disappears. At this time, the clamping block 702 will reset under the elasticity of the reset spring 703 and return to the square slot 701.

[0050] See also Figure 4-7 As shown, the rotating assembly 4 includes two mounting plates 401, and the two mounting plates 401 are symmetrically welded on the outer wall of the lower shell 104. A dual-axis motor 402 is fixedly penetrated on one mounting plate 401, and a driving gear 403 is fixedly sleeved on the outer wall of the top output end of the dual-axis motor 402. A gear ring 1011 is fixed on the outer wall of the upper shell 101, and the driving gear 403 is meshed and connected with the gear ring 1011;

[0051] The separation component 5 includes two threaded rods 502, two plug-in rods 504 and a lifting plate 507. A rotating shaft 503 is passed through another mounting plate 401. The two plug-in rods 504 are respectively fixed to the output end of the top of the dual-axis motor 402 and the top surface of the rotating shaft 503. The two ends of the lifting plate 507 are sleeved on the two threaded rods 502. The lifting plate 507 is rotatably connected to the top center of the upper shell 101 through the center rod 5072. The top of the outer wall of the upper shell 101 is integrally fixed with an edge plate 1012. L-shaped support plates 5071 are provided on both sides of the lower surface of the lifting plate 507. The L surfaces of the two L-shaped support plates 5071 are in contact with the lower surface of the edge plate 1012 and are slidably connected. The bottom ends of the two threaded rods 502 are provided with plug-in grooves 5022 matching the plug-in rods 504. The clamping component 7 is arranged on the two plug-in rods 504.

[0052] A protective box 204 is fixed to the bottom of the air supply box 2, and the bottom output end of the dual-axis motor 402 and the bottom of the rotating shaft 503 are both inserted through the top surface of the protective box 204 and are rotatably connected to the inner bottom wall thereof, and the bottom output end of the dual-axis motor 402 and the bottom outer wall of the rotating shaft 503 are both fixedly sleeved with a transmission wheel 505, and the two transmission wheels 505 are connected to each other through a transmission chain 506. The upper surfaces of the two mounting plates 401 on the side away from the lower shell 104 are both installed with L-shaped frame plates 501 by bolts, and the L ends of the two L-shaped frame plates 501 are both sleeved on the bottom outer wall of the threaded rod 502, the bottom end of the center rod 5072 is fixedly connected to the top of the upper shell 101, and the lifting plate 507 is rotatably connected to the center rod 5072;

[0053] When the threaded rod 502 is connected to the plug rod 504 through the clamping assembly 7, the two output ends of the dual-axis motor 402 respectively drive the connected plug rod 504 and the transmission wheel 505 to rotate. The transmission wheel 505 drives the rotating shaft 503 to rotate through the transmission chain 506, and the rotating shaft 503 drives the other plug rod 504 to rotate. At this time, the two plug rods 504 both drive the threaded rod 502 to rotate through the extended clamping block 702, so that the lifting plate 507 moves upward following the rotation of the threaded rod 502, and drives the upper shell 101 to move and separate from the lower shell 104 through the L-shaped support plate 5071 and the edge plate 1012. The upwardly moved upper shell 101 will also drive the gear ring 1011 to move, so that the gear ring 1011 is separated from the driving gear 403. When the dual-axis motor 402 works in the reverse direction, it will drive the gear ring 1011 to engage with the driving gear 403 when the upper shell 101 moves downward.

[0054] When the threaded rod 502 is separated from the plug-in rod 504, the output end of the dual-axis motor 402 will respectively drive the driving gear 403 and the rotating shaft 503 to rotate. At this time, the two plug-in rods 504 will rotate in the plug-in slot 5022 of the threaded rod 502, and the driving gear 403 will drive the meshing ring gear 1011 to rotate, and transmit power to the ring gear 1011 through meshing, thereby driving the upper shell 101 to rotate along the lower shell 104.

[0055] The working principle of the present invention is:

[0056] First, the electromagnet 5021 is energized through an external controller to generate magnetism. The magnetism penetrates the rod wall of the threaded rod 502 to absorb the clamping block 702 located in the plug-in slot 5022. The clamping block 702 is affected by the magnetism and extends out of the square slot 701 and inserts into the clamping slot 704, and stretches the reset spring 703, thereby completing the connection between the threaded rod 502 and the plug-in rod 504. At this time, the dual-axis motor 402 is started through the controller. When the dual-axis motor 402 works, its two output ends respectively drive the connected plug-in rod 504 and the transmission wheel 505 to rotate. The transmission wheel 505 drives the rotating shaft 503 to rotate through the transmission chain 506, and the rotating shaft 503 drives the other plug-in rod 504 to rotate. At this time, both plug-in rods 504 are rotated through the extended clamping block 701. The connecting block 702 drives the threaded rod 502 to rotate, so that the lifting plate 507 moves upward following the rotation of the threaded rod 502, and drives the upper shell 101 to move and separate from the lower shell 104 through the L-shaped support plate 5071 and the edge plate 1012. The upper shell 101 that moves upward will also drive the gear ring 1011 to move, so that the gear ring 1011 is separated from the driving gear 403, and the aeration pipe 202 to be replaced is screwed into the connecting pipe 201. The dual-axis motor 402 is started in the reverse direction to move the upper shell 101 downward until the outer groove wall of the first slot 1013 is inserted into the groove of the second slot 1041, and the electromagnet 5021 is powered off, and the magnetism disappears. At this time, the clamping block 702 will be reset under the elasticity of the reset spring 703 and return to the square slot 701;

[0057] Then the staff unscrews the blocking block and adds the microalgae, culture solution and water into the liquid storage tank 1 through the addition port 103. Then the dual-axis motor 402 starts working, and the output end of the dual-axis motor 402 will respectively drive the driving gear 403 and the rotating shaft 503 to rotate. At this time, the two plug-in rods 504 will rotate in the plug-in groove 5022 of the threaded rod 502, and the driving gear 403 will drive the meshing ring gear 1011 to rotate, and transmit power to the ring gear 1011 through meshing, thereby driving the upper shell 101 to rotate along the lower shell 104, and driving the stirring rod 102 to stir the water, so as to evenly distribute the microalgae inside the liquid storage tank 1. At this time, the carbon dioxide supply system will send the collected carbon dioxide flue gas into the air supply box 2 through the supply pipe and the connecting pipe 201, and then pass through multiple aeration pipes 202 to form small bubbles that dissolve in the water, and use the photosynthesis of the microalgae to fix carbon dioxide. Finally, the microalgae and water can be discharged through the discharge pipe 1042.
