Description

Technical Field

[0001] This utility model relates to the field of Haematococcus pluvialis cultivation technology, and in particular to a carbon dioxide supply device for cultivating Haematococcus pluvialis. Background Technology

[0002] Haematococcus pluvialis, a precious microalga rich in astaxanthin, requires extremely high efficiency and uniformity in carbon dioxide supply during its large-scale cultivation. A proper supply of carbon dioxide directly affects the photosynthetic efficiency, growth rate, and product accumulation of Haematococcus pluvialis. However, existing carbon dioxide supply devices for cultivating Haematococcus pluvialis have significant technical defects. The core problem lies in the insufficient structural design and position adjustment capability of the gas distribution pipe, leading to uneven distribution of carbon dioxide gas in the algal solution and low gas supply efficiency.

[0003] In existing technologies, the gas distribution pipes of carbon dioxide supply devices mostly adopt a single straight pipe structure, and the position of the gas distribution pipe is fixed, making it impossible to adjust the height according to the depth of the algal solution in the incubator and the different growth stages of Haematococcus pluvialis. This design causes the carbon dioxide gas to concentrate and rise after being released from the outlet, forming an effective gas supply area only in the upper layer of the algal solution. The lower layer of algal solution has difficulty contacting sufficient carbon dioxide, resulting in a layered difference in the growth of Haematococcus pluvialis, with a slow overall growth rate and low yield.

[0004] Therefore, it is necessary to provide a carbon dioxide supply device for cultivating Haematococcus pluvialis to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a carbon dioxide supply device for cultivating Haematococcus pluvialis, which solves the problem of uneven distribution in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides a carbon dioxide supply device for cultivating Haematococcus pluvialis. A culture vessel is installed on the base, and a top cover is installed on the top of the culture vessel. An electric telescopic rod is vertically installed on the top surface of the top cover. The output end of the electric telescopic rod passes through the surface of the top cover and is connected to a drive rod. A first serpentine gas distribution pipe is installed at the bottom of the drive rod, and a second serpentine gas distribution pipe communicates internally with the first serpentine gas distribution pipe. Gas outlets are installed on the peripheral sides of both the first and second serpentine gas distribution pipes, and one-way valves are installed on the gas outlets. One end of the first serpentine gas distribution pipe is connected to the gas supply component via a flexible gas guide hose. The electric telescopic rod can adjust the height of the first and second serpentine gas distribution pipes by driving the drive rod. The carbon dioxide supplied by the gas supply component is diverted from the first serpentine gas distribution pipe to the second serpentine gas distribution pipe, and then released into the algal solution through the gas outlets. The one-way valve prevents the algal solution from flowing back into the gas distribution pipes.

[0007] Preferably, the gas supply assembly includes a gas storage cylinder, a gas pump, a cooling cylinder, and a refrigeration assembly. The gas storage cylinder is placed on the base, and the gas pump is installed on one side of the gas storage cylinder. The gas pump input end is connected to the gas storage cylinder through a pipe, and the gas pump output end is connected to the cooling cylinder through a pipe. One end of the cooling cylinder is connected to the gas delivery hose through a gas guide pipe that passes through the surface of the incubator. The refrigeration assembly is installed inside the cooling cylinder. The gas pump can extract carbon dioxide from the gas storage cylinder and send it into the cooling cylinder. The refrigeration assembly cools the carbon dioxide in the cooling cylinder. The cooled carbon dioxide is then transported to the first serpentine gas distribution pipe through the gas guide pipe and the gas delivery hose.

[0008] Preferably, multiple air outlets are installed, and the multiple air outlets are equidistantly surrounding the periphery of the first and second serpentine air distribution pipes; the multiple air outlets, in conjunction with the structure of the serpentine air distribution pipes, can make carbon dioxide be released evenly from different positions, thereby improving the uniformity of gas distribution in the algal liquid.

[0009] Preferably, a temperature sensor is installed inside the cooling cylinder; the temperature sensor can monitor the temperature of carbon dioxide inside the cooling cylinder, providing a reference for the operation of the refrigeration components, so as to achieve precise control of the gas temperature.

[0010] Preferably, a feed hopper is installed on the top surface of the top cover, and a discharge pipe is installed below the surface of the incubator, with a valve installed on the discharge pipe; the feed hopper can be used to add materials into the incubator, and after the valve is opened, the materials in the incubator can be discharged through the discharge pipe.

[0011] Preferably, two electric telescopic rods are installed, symmetrically mounted on the top surface of the top cover; the two symmetrical electric telescopic rods can more stably drive the drive rod and air distribution pipe to adjust the height, ensuring the smoothness of the adjustment process.

[0012] Preferably, a matching controller is installed on the base; the controller can coordinate the operation of components such as the electric telescopic rod, air pump, and refrigeration components, so that all parts of the device work together to meet the gas supply requirements for the cultivation of Haematococcus pluvialis.

[0013] Compared with related technologies, the carbon dioxide supply device for cultivating Haematococcus pluvialis provided by this utility model has the following beneficial effects: Compared with existing technologies, the carbon dioxide supply device for cultivating Haematococcus pluvialis features an electrically operated telescopic rod that allows for flexible height adjustment of the first serpentine gas distribution pipe and the internally connected second serpentine gas distribution pipe, adapting to different algal solution depths and various growth stages of Haematococcus pluvialis. The double serpentine structure significantly increases the effective coverage area for gas release. Combined with multiple sets of equidistantly surrounding gas outlets, carbon dioxide gas can diffuse evenly from different lateral positions, preventing bubbles from accumulating and rising. This ensures that the upper and lower layers of the algal solution are fully in contact with the gas, solving the problem of gas stratification in traditional devices. Furthermore, the diversion design of the double serpentine gas distribution pipes improves the uniformity of gas supply, ensuring the consistency of Haematococcus pluvialis growth and the overall growth rate.

[0014] Compared with existing technologies, the carbon dioxide supply device for cultivating Haematococcus pluvialis can precisely control the temperature of carbon dioxide through the cooling cylinder and refrigeration components, avoiding the impact of high-temperature gas on the activity of Haematococcus pluvialis. The cooperation of the gas pump and pipeline ensures stable gas supply pressure, further improving the photosynthetic efficiency and product accumulation of Haematococcus pluvialis.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0019] Please refer to the following: Figure 1-5 This is a carbon dioxide supply device for cultivating Haematococcus pluvialis. The base 1 serves as the supporting foundation for the entire device. A culture vessel 2, containing Haematococcus pluvialis and algal solution, is fixedly installed on top of the base 1. A top cover 4 is installed at the top of the culture vessel 2 through a sealed fit. The top cover 4 provides both enclosed protection for the culture vessel 2 and a mounting platform for the upper components. An electric telescopic rod 5 is vertically fixed to the top surface of the top cover 4. The output end of the electric telescopic rod 5 passes vertically through the surface of the top cover 4 and is fixedly connected to the top of a drive rod 15. The bottom end of the drive rod 15 is fixedly connected to a first serpentine gas distribution pipe 10, forming a transmission chain of "electric telescopic rod 5 - drive rod 15 - gas distribution pipe". A second serpentine gas distribution pipe 11 and the first serpentine gas distribution pipe 10 are internally connected to form a mutually cooperating diversion structure. The peripheral surfaces of both the first serpentine gas distribution pipe 10 and the second serpentine gas distribution pipe 11 are fixed. An outlet 12, which runs through the interior of the gas distribution pipe, is installed. Each outlet 12 is equipped with a one-way valve to prevent backflow of algal liquid through the one-way flow design. One end of the first serpentine gas distribution pipe 10 is flexibly connected to the gas supply component through a flexible gas guide hose 13 that can be adjusted according to the height of the gas distribution pipe. During operation, the electric telescopic rod 5 drives the drive rod 15 to move up and down through the telescopic movement, thereby adjusting the height of the first and second serpentine gas distribution pipes 11 in the algal liquid to adapt to different needs. The carbon dioxide delivered by the gas supply component enters the first serpentine gas distribution pipe 10 through the gas guide hose 13, and is then diverted to the second serpentine gas distribution pipe 11 through the internal through-structure. Finally, it is released synchronously by the outlets 12 on the periphery of the two gas distribution pipes. The structure of the double serpentine gas distribution pipe expands the lateral coverage of gas release, realizes the uniform distribution of carbon dioxide in the algal liquid, and solves the problem of gas stratification in traditional devices. Example

[0020] Please refer to the following: Figure 1-5The gas supply assembly includes a gas cylinder 8, a gas pump 7, a cooling cylinder 6, and a refrigeration component 17. It provides power, storage, and processing functions for carbon dioxide supply. The gas cylinder 8 is placed on a base 1 for stable support. The gas pump 7 is fixedly installed on one side of the gas cylinder 8. The input end of the gas pump 7 is connected to the inside of the gas cylinder 8 through a pipe to form a gas extraction channel. The output end of the gas pump 7 is connected to the inside of the cooling cylinder 6 through another pipe to form a gas delivery channel. One end of the cooling cylinder 6 passes through the surface of the incubator 2 via a gas guide pipe 14 and connects to a gas guide hose 13, realizing the transmission of cooled gas to the gas distribution pipe. The refrigeration component 17 is fixedly installed inside the cooling cylinder 6 and comes into direct contact with the flowing carbon dioxide. During operation, the air pump 7 draws carbon dioxide from the gas storage cylinder 8 through the input pipe and then pressurizes the gas into the cooling cylinder 6 through the output pipe. The refrigeration component 17 cools the carbon dioxide in the cooling cylinder 6 to prevent high-temperature gas from entering the algal liquid and affecting the activity of the red algae. The cooled carbon dioxide is then transmitted to the first serpentine gas distribution pipe 10 through the gas guide pipe 14 and the gas guide hose 13. The stable pressure provided by the air pump 7, combined with the sealed connection of the pipe, ensures a continuous and stable supply of carbon dioxide and improves the gas supply efficiency.

[0021] The cooling component 17 includes a semiconductor cooling chip and heat dissipation fins. The semiconductor cooling chip is fixed to the inner wall of the cooling cylinder 6 by bolts. The heat dissipation fins are welded to the heat dissipation end of the semiconductor cooling chip and extend to the outside of the cooling cylinder 6. When the semiconductor cooling chip is energized, it generates a temperature difference between the hot and cold ends, and directly cools the carbon dioxide flowing through the cooling cylinder 6 through the cold end. The cooling power can be adjusted by the controller 9, and the adjustment range is 50-200W. Example

[0022] Please refer to the following: Figure 1-5 Multiple gas outlets 12 are fixedly installed on the peripheral side of the first serpentine gas distribution pipe 10 and the second serpentine gas distribution pipe 11, and the gas outlets 12 are distributed in a circumferential manner at equal distances, forming multi-directional and uniform gas release points. This installation method allows carbon dioxide to be released synchronously from different positions of the two serpentine gas distribution pipes. Combined with the curved structure of the serpentine gas distribution pipes, the release range of gas in the algal liquid is greatly increased, avoiding the problem of concentrated floating of bubbles under the traditional single straight pipe structure. This allows carbon dioxide to come into contact with all areas of the algal liquid, further improving the uniformity of gas distribution. Example

[0023] Please refer to the following: Figure 1-5Temperature sensor 18 is fixedly installed inside cooling cylinder 6, and its sensing end is in direct contact with carbon dioxide flowing through cooling cylinder 6 to monitor gas temperature in real time. Temperature sensor 18 feeds back the signal to controller 9 by sensing the gas temperature. Controller 9 adjusts the operating status of cooling component 17 according to preset temperature range so that the carbon dioxide temperature in cooling cylinder 6 is always kept in a suitable range for the growth of halophyte, so as to achieve precise control of gas temperature and avoid temperature fluctuations from affecting the photosynthetic efficiency of halophyte. Example

[0024] Please refer to the following: Figure 1-5 The feed hopper 3 is fixedly installed on the top surface of the top cover 4, and its bottom is connected to the inside of the incubator 2, which facilitates the addition of nutrients or algae seeds required for the growth of Haematococcus pluvialis into the incubator 2. The discharge pipe 16, which is connected to the inside of the incubator 2, is fixedly installed below the surface of the incubator 2. A valve is fixedly installed on the discharge pipe 16, and the valve controls the opening and closing of the discharge pipe 16. The cooperation between the feed hopper 3 and the top cover 4 allows the addition of materials without opening the top cover 4, reducing gas leakage in the incubator 2. The cooperation between the discharge pipe 16 and the valve allows the Haematococcus pluvialis and algae liquid to be discharged from the discharge pipe 16 by opening the valve after cultivation, realizing convenient material entry and exit without interfering with the normal operation of the gas supply system. Example

[0025] Please refer to the following: Figure 1-5 Two electric telescopic rods 5 are vertically fixed on the top surface of the top cover 4, and are symmetrically distributed about the central axis of the top cover 4. Their output ends are connected to the corresponding positions of the drive rod 15. The two symmetrically installed electric telescopic rods 5 extend and retract synchronously during operation. Through the balanced force, the drive rod 15 and the bottom gas distribution pipe move smoothly up and down, avoiding tilting or shaking of the gas distribution pipe during height adjustment. This ensures that the height of each part of the gas distribution pipe in the algae liquid is consistent, thereby ensuring the uniformity of gas release. Example

[0026] Please refer to the following: Figure 1-5 A controller 9, matching each component of the device, is fixedly installed on the base 1. The controller 9 is connected to electrical components such as the electric telescopic rod 5, the air pump 7, the refrigeration component 17, and the temperature sensor 18 through circuits, forming a unified control center. The controller 9 receives the temperature signal from the temperature sensor 18 and regulates the operation of the refrigeration component 17. It controls the extension and retraction of the electric telescopic rod 5 according to the growth stage of Haematococcus pluvialis or the depth of the algal solution to adjust the height of the gas distribution pipe. At the same time, it controls the start and stop of the air pump 7 and its output power to ensure the supply and pressure of carbon dioxide are stable. By coordinating the coordinated work of each component, the device as a whole meets the requirements of Haematococcus pluvialis cultivation for carbon dioxide supply efficiency and uniformity, ultimately improving the growth rate and product accumulation of Haematococcus pluvialis.

[0027] It should be noted that the control circuit of controller 9 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0028] The working principle of the carbon dioxide supply device for culturing Haematococcus pluvialis provided by this utility model is as follows: The controller 9 coordinates the operation of all components of the device. The gas storage cylinder 8 stores carbon dioxide. After the gas pump 7 starts, it draws carbon dioxide from the gas storage cylinder 8 through the pipeline and sends it into the cooling cylinder 6. The refrigeration component 17 in the cooling cylinder 6, with the cooperation of the temperature sensor 18, precisely cools the carbon dioxide to make the gas temperature meet the growth requirements of Haematococcus pluvialis. The cooled carbon dioxide is then transported sequentially through the gas guide pipe 14 and the gas guide hose 13 to the first serpentine gas distribution pipe 10. From the first serpentine gas distribution pipe 10, it is diverted to the internally connected second serpentine gas distribution pipe 11. Finally, it is evenly released into the culture medium through multiple gas outlets 12 installed at equal intervals around the periphery of the two gas distribution pipes. In the algal solution in the incubator 2, the one-way valve on the air outlet 12 can effectively prevent the algal solution from flowing back into the gas distribution pipe. At the same time, according to the depth of the algal solution in the incubator 2 and the gas supply requirements of different growth stages of Haematococcus pluvialis, the controller 9 can control the two symmetrically installed electric telescopic rods 5 to extend and retract, driving the drive rod 15 and the first and second serpentine gas distribution pipes 11 connected to the bottom to move up and down, realizing the precise adjustment of the height of the gas distribution pipe, ensuring that each layer of algal solution can obtain sufficient carbon dioxide. During the cultivation process, nutrients can be added to the incubator 2 through the feed hopper 3 at the top of the top cover 4. After the cultivation is completed, the valve on the discharge pipe 16 below the incubator 2 can be opened to collect the Haematococcus pluvialis products.
