Description

Technical Field

[0001] The invention belongs to the technical field of microalgae cultivation, and in particular relates to a microalgae cultivation device. Background Art

[0002] Microalgae refers to those tiny algae groups whose morphology can only be distinguished under a microscope. Microalgae usually refers to the general term for microorganisms that contain chlorophyll a and can perform photosynthesis, and are a type of protists. Microalgae that are cultivated or produced in large quantities using biotechnology belong to four algae phyla: Cyanobacteria, Chlorophyta, Chrysophyta, and Rhodophyta.

[0003] Currently, commonly used microalgae cultivation devices mainly include open systems and closed systems. Open systems are widely used because of their low cost and simple operation, but open cultivation devices generally have disadvantages such as low microalgae photosynthetic efficiency, easy pollution, and poor reaction mixing. Existing culture devices easily cause microalgae to adhere to the wall and sink to the bottom in large quantities. Microalgae themselves tend to grow on the wall, which will cause the microalgae to easily adhere to the outlet that provides carbon dioxide, thereby causing blockage and affecting the contact between carbon dioxide and microalgae. At the same time, when the water body is unevenly stirred and the microalgae sink to the bottom in large quantities, it will have a shading effect on the microalgae at the bottom, thereby making it impossible for the microalgae at the bottom to react and utilize light and nutrients, resulting in the death of the microalgae, so there is room for improvement.

[0032] Furthermore, the mounting frame is provided with a driving motor which is transmission-connected to the rotating tube.

[0033] Example 1: Figure 1-10As shown, a microalgae cultivation device of the present invention comprises a transparent cultivation tank 1 and a lifting mechanism 11, a mounting frame 12 is installed at the upper end of the lifting mechanism 11, a cultivation cover 13 detachably connected to the transparent cultivation tank 1 is installed at the lower end of the mounting frame 12, an air supply pipe 14 is connected through the mounting frame 12, a rotating tube 15 sealingly connected to the air supply pipe 14 is rotatably installed at the lower end of the mounting frame 12, a driving motor 17 drivingly connected to the rotating tube 15 is installed on the mounting frame 12, the rotating tube 15 extends into the transparent cultivation tank 1 and is provided with a plurality of one-way air outlets 16, and an exhaust assembly is installed at the upper end of the cultivation cover 13; A tripod 20 rotatably connected to the rotating tube 15 is fixedly connected inside the breeding cover 13, and three photosynthesis components are installed on the tripod 20. The photosynthesis components include a light-transmitting part. An engaging groove 21 is provided on the circumference of the rotating tube 15. A first gear 22 meshing with the engaging groove 21 is rotatably connected to the upper side of the tripod 20. The first gear 22 is connected to the installation shaft 23 through a driving assembly. The light-transmitting part is installed on the lower end of the installation shaft 23, and a fill light 24 is installed on the circumference of the transparent breeding tank 1.

[0034] A third gear is installed on the peripheral side of the rotating tube 15, so that the fourth gear connected to the driving motor 17 drives the third gear meshing with it to rotate, thereby driving the rotating tube 15 to rotate. At the same time, the arc-shaped breeding cover 13 can make the mixed and raised microalgae solution approach the rotating tube 15 so as to better contact with the carbon dioxide. A latch that slides up and down is provided between the transparent breeding tank 1 and the breeding cover 13, so that the breeding cover 13 cannot rotate when inserted, and the exhaust component is installed on the upper side of the breeding cover 13 to discharge the oxygen produced by the microalgae. When in use, the microalgae solution is first added to the transparent breeding tank 1, and then the breeding cover 13 is driven by the lifting mechanism 11 to close the transparent breeding tank 1. After closing, the breeding tank 13 is connected to the transparent breeding tank 1, so that the breeding cover 13 will not be driven to rotate when the rotating tube 15 rotates. At this time, the gas pipe 14 is firmly connected to the output end of the carbon dioxide storage device and carbon dioxide is quantitatively input at a uniform speed, thereby The pressure of carbon dioxide entering the rotating tube 15 through the gas pipe 14 and being discharged from the one-way air outlet 16 is the same. At this time, the driving motor 17 is started to drive the rotating tube 15 to rotate so that the carbon dioxide discharged from the one-way air outlet 16 can be discharged 360 degrees in all directions during the rotation of the rotating tube 15, thereby increasing the contact area between the carbon dioxide and the microalgae solution. At the same time, during the rotation of the rotating tube 15, the first gear 22 is driven to rotate, and the mounting shaft 23 and the light-transmitting member are driven to rotate through the driving assembly, and the fill light 24 and the sunlight or the light source of the indoor fluorescent lamp are refracted and transmitted through the light-transmitting member, so that the light source can act on different positions of the microalgae solution through the light-transmitting member. At the same time, the light-transmitting member continuously rotates to refract different light sources, so that the light source can irradiate the center of the transparent breeding tank 1, thereby avoiding that the transparent breeding tank 1 cannot be irradiated with the light source and affects photosynthesis, thereby improving the photosynthesis efficiency and effect.

[0035] The present invention can drive the rotating tube 15 to rotate and spray carbon dioxide by driving the motor, thereby increasing the contact area between the carbon dioxide and the microalgae. At the same time, the rotating tube 15 drives the light-transmitting member to rotate during the rotation of the rotating tube 15, and further refracts the external light source through the light-transmitting member, thereby avoiding the different effects of the solution inside the microalgae and the solution outside contacting the light source, thereby affecting photosynthesis. At the same time, the refraction of the light-transmitting member can improve the contact efficiency between the light source and the microalgae solution.

[0036] Embodiment 2: Based on Embodiment 1, a further improvement is made, the lower end of the tripod 20 is rotatably connected to a gear ring 30, the lower end of the gear ring 30 is fixedly mounted with a mounting plate 31 slidably connected to the first gear 22, and the lower end of the mounting plate 31 is symmetrically mounted with a cleaning assembly; The cleaning assembly includes a mounting box 32 sealed against the rotating tube 15 , and stirring rods 33 are mounted on both sides of the mounting box 32 .

[0037] During the rotation of the first gear 22, the gear ring 30 meshing therewith will be driven to rotate, thereby driving the mounting plate 31 and the mounting box 32 of the cleaning assembly to rotate. During the rotation of the mounting box 32, the side wall of the rotating tube 15 will be cleaned to prevent the microalgae from adhering to the surface of the rotating tube 15 and to prevent the one-way air outlet 16 from being blocked. At the same time, during the rotation of the mounting box 32, the stirring rod 33 can stir the microalgae solution to improve the contact efficiency between the microalgae and the carbon dioxide. At the same time, since the flow rate of carbon dioxide entering the rotating tube 15 is constant, when the mounting box 32 blocks part of the one-way air outlet 16, the distance of the carbon dioxide discharged from the connected one-way air outlet 16 will be farther under the action of pressure, thereby improving the contact reaction between the microalgae far away from the rotating tube 15 and the carbon dioxide. When the mounting box 32 does not block the one-way air outlet 16, all the one-way air outlets 16 are connected to the outside to restore the normal carbon dioxide emission distance.

[0038] A one-way air inlet 34 matching the one-way air outlet 16 is provided on the side of the installation box 32 facing the rotating tube 15, and an inclined surface 35 is provided on the side of the installation box 32 facing the rotating tube 15. A rotating column 36 is symmetrically sealed and rotatably connected inside the installation box 32. The two rotating columns 36 are evenly provided with one-way connecting holes 37 matching the one-way air outlet 16. A driving gear 38 is installed on the upper ends of the two rotating columns 36, and the rotating tube 15 is evenly installed with a plurality of driving teeth 39 meshing with the driving gear 38.

[0039] In the process of the mounting plate 31 driving the mounting box 32 to rotate, carbon dioxide will be input into the mounting box 32 through the one-way communication hole 37. Since the rotation direction of the gear ring 30 is the same as that of the first gear 22, that is, the rotation direction of the gear ring 30 is opposite to that of the rotating tube 15, the mounting plate 31 will drive the mounting box 32 and the driving gear 38 to rotate, and the driving gear 38 will drive the rotating column 36 to rotate the meshing angle of the driving gear 39. In this way, the continuous relative rotation will cause the rotating column 36 to rotate with the assistance of the driving gear 38 and the driving gear 39, thereby making the one-way communication hole 37 at a certain moment. The hole 37 is connected to the inside and outside of the installation box 32, and the one-way air outlet 16 is connected to the one-way connecting hole 37. At this time, the carbon dioxide discharged from the one-way air outlet 16 is blown from the one-way connecting hole 37 to the rotating tube 15 and the one-way air outlet 16, and the attached microalgae are blown away from the rotating tube 15. In this way, the rotating tube 15 is cleaned in conjunction with the hanging test of the rotating tube 15 to avoid the microalgae from being damaged during the hanging test of the installation box 32. At the same time, when the one-way connecting hole 37 is not connected to the inside and outside of the installation box 32 and the installation box 32 blocks some of the one-way air outlets 16, the effective distance of the carbon dioxide sprayed from other one-way air outlets 16 will be further away.

[0040] A reflective layer 40 is installed on the side of the mounting box 32 away from the rotating tube 15. The reflective layer 40 can frequently reflect the incoming light source to increase the contact between the microalgae and the light source. At the same time, reflective layers 40 of different colors can be configured to match different microalgae. For example, different microalgae have different absorption of light: this difference is related to their pigment composition. The pigment composition of green algae, brown algae and red algae is different, resulting in different sensitivities to light of different wavelengths. For example, chlorophyll in green algae mainly absorbs red-orange light, while phycoerythrin in red algae mainly absorbs blue light. The driving assembly includes a first sprocket 42 fixedly mounted on the first gear 22, a second sprocket 43 is mounted on the outer side of the mounting shaft 23, and a chain 423 is mounted between the first sprocket 42 and the second sprocket 43. The first sprocket 42 rotates with the first gear 22, and then drives the second sprocket 43 and the mounting shaft 23 to rotate through the chain 423, and the rotation of the mounting shaft 23 drives the light-transmitting member to rotate.

[0041] The light-transmitting component includes a hollow prism 41, a second sprocket 43 and a mounting shaft 23 connected to the hollow prism 41, a rotating joint 44 drivingly connected to the second sprocket 43 is installed on the upper end of the tripod 20, a water storage ring box 45 is installed on the upper end of the rotating joint 44, and the water storage ring box 45 is connected to an external water source, an L-shaped water trough 46 is provided at the bottom of the hollow prism 41, and a plurality of one-way water outlet holes 47 are provided in the L-shaped water trough 46. The connection between the side edges of the hollow prism 41 and the one-way water outlet holes 47 is chamfered, a mounting groove is provided at the bottom of the hollow prism 41, and a sealing column 48 slidably connected to the mounting groove is fixedly connected to the upper end of the sealing column 48 with a piston 49 sealingly and slidably connected to the hollow prism 41, and an elastic component is installed at the bottom of the sealing column 48.

[0042] In the initial state, when the culture tank 13 is connected to the transparent culture tube 1, the elastic component abuts against the transparent culture tank 1. At this time, the elastic component makes the piston 49 located on the upper side of the water inlet of the L-shaped water tank 46. In this way, the hollow prism 41 is filled with water to make the interior of the hollow prism 41 in a solid state. The hollow prism 41 can refract the light source and separate the complex white light composed of various monochromatic lights. At the same time, refraction occurs to photosynthesize with microalgae at different positions. Moreover, under the action of the composite light, the dispersed monochromatic light is more convenient for the microalgae to photosynthesize with the corresponding monochromatic light.

[0043] When cleaning is needed, the contact breeding cover 13 is locked with the transparent breeding tank 1, and then the breeding cover 13 is driven to move upward but not completely opened, so that the transparent breeding tank 1 limits the breeding cover 13 and cannot rotate, while preventing the cleaning water from flowing out of the gap between the transparent breeding tank 1 and the breeding cover 13; When the breeding cover 13 moves slightly upward under the drive of the lifting mechanism 11, the elastic component will move downward under the action of the rebound force, and then the piston 49 will move downward to connect the L-shaped water tank 46 and the hollow prism 41. In this way, when cleaning water is added to the water storage ring box 45 through an external water source, the water will flow into the L-shaped water tank 46 and be discharged from the one-way water outlet 47 to act on the inside of the transparent breeding tank 1 for cleaning. The driving motor 17 drives the hollow prism 41 to rotate, so that the one-way water outlet 47 rotates to spray cleaning liquid for cleaning.

[0044] The elastic component includes an abutment block 50 installed at the bottom of the sealing column 48, a limit block 51 is fixedly installed in the middle of the sealing column 48, and a first spring 52 is installed between the limit block 51 and the installation groove. When the abutment block 50 abuts against the transparent breeding tank 1, the first spring 52 is in a compressed state, so that the piston 49 is located above the L-shaped water tank 46. When the breeding cover 13 moves upward, the abutment block 50 will move downward under the rebound force of the first spring 52, thereby driving the piston 49 to move downward and leak out of the L-shaped water tank 46.

[0045] The lifting mechanism includes two telescopic rods 53 and two electric telescopic rods 54, and the fill light 24 is installed on the two telescopic rods 53 and the two electric telescopic rods 54 facing the transparent breeding tank 1. The one-way air outlet 16, the one-way air inlet 34, the one-way communication hole 37, and the one-way water outlet 47 can be connected in one direction by installing a one-way valve.

[0046] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
