Description

Technical Field

[0001] This utility model relates to the field of algal carbon dioxide culture, and in particular to an algal carbon dioxide aeration culture control device. Background Technology

[0002] Algal carbon dioxide aeration culture technology artificially regulates carbon dioxide supply and optimizes environmental conditions such as light and temperature. It precisely introduces an appropriate amount of carbon dioxide into the artificial culture system, breaking through the carbon limitations of the natural environment. Based on the algal species, growth stage and target product characteristics, it adapts the carbon dioxide concentration and aeration rate, while balancing parameters such as pH and nutrients. This can not only promote the rapid accumulation of algal biomass, increasing the density several times compared to the natural state, but also directionally regulate metabolic pathways and optimize the content of target products such as lipids and pigments.

[0003] However, in existing technologies, the bubbles generated by aeration devices lack a flow guidance mechanism, resulting in uneven distribution of bubbles in the culture medium. This not only reduces the gas-liquid contact area but also causes an imbalance in the carbon dioxide concentration distribution in the middle of the liquid, affecting the uniform absorption of carbon sources by algae. At the same time, existing systems fail to achieve automatic cleaning functions for aeration devices and air delivery components. Long-term use can easily lead to pipe blockage or reduced aeration efficiency due to algae adhesion and calcium carbonate precipitation, further exacerbating the instability of the culture environment and restricting the efficiency and stability of algae cultivation.

[0004] In view of this, this paper studies and improves existing problems to provide a carbon dioxide aeration and cultivation control device for algae. The fan blades bypass the flow to solve the problem of uneven bubble distribution and improve CO2 utilization. The multi-component collaboration reduces pollution and ensures stable system operation. Automatic cleaning and drying reduce maintenance costs and extend lifespan. The aim of this technology is to solve problems and improve practical value. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a carbon dioxide aeration and cultivation control device for algae. This invention mixes CO2 and purified air in a mixing tank, then delivers the mixture through an air supply pipe to an aerator to release bubbles. Fan blades circulate the air, promoting uniform bubble distribution. A photosynthetic lamp provides illumination, an exhaust valve balances the gas, and a control base stabilizes parameters. A rinsing component cleans and dries the pipeline. The fan blades' circulation solves the problem of uneven bubble distribution, improving CO2 utilization. Multiple components work together to reduce pollution and ensure stable system operation. Automatic cleaning and drying reduce maintenance costs and extend lifespan. The modular design adapts to various scenarios, offering flexibility and high efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an algae carbon dioxide aeration culture control device, comprising a culture tank, an air supply pipe, a mixing tank, a conveying pipe, and a rinsing assembly. The air supply pipe is detachably connected to the middle of one side of the culture tank, the mixing tank is detachably connected to the outer surface of one end of the air supply pipe, the conveying pipe is detachably connected to the middle of the upper end of the mixing tank, and the rinsing assembly is detachably connected to the middle of the air supply pipe.

[0007] The culture tank includes a transparent tank, with a control base sealed to the lower outer surface of the transparent tank. A culture support frame is fixedly connected to the upper outer surface of the control base. An aerator is detachably connected to the middle of the control base. A submersible motor is fixedly connected to the middle of the culture support frame. A fan blade is detachably connected to the lower middle of the submersible motor. The transparent tank of the culture tank provides growth space for algae. The lower control base supports and connects to the aerator. The bubbles released by the aerator are rotated by the fan blade driven by the submersible motor on the culture support frame to form a flow around the aerator, so that the bubbles are evenly distributed, improving the gas-liquid contact efficiency, making the carbon dioxide distribution more uniform, and promoting algae growth.

[0008] The rinsing assembly includes a rinsing support frame. A rinsing pump and a heating device are detachably connected to the upper outer surface of the rinsing support frame. The heating device is located on one side of the rinsing pump. A water tank is fixedly connected to the upper outer surface of the rinsing pump. An air inlet pipe is detachably connected to the upper middle part of the heating device. The rinsing support frame supports the rinsing pump and the heating device. The rinsing pump draws water from the water tank to rinse the relevant components. The heating device introduces air through the air inlet pipe and heats it, which can dry the water stains remaining after rinsing. This achieves automatic cleaning and drying of the device, avoids pipe blockage and corrosion, reduces manual maintenance, and ensures stable operation of the device.

[0009] Preferably, the upper outer surface of the transparent container is detachably connected to a sealing cap, the upper middle part of the sealing cap is sealed with an exhaust valve, and the lower middle part of the sealing cap is sealed with a photosynthetic lamp. The sealing cap at the upper end of the transparent container enables airtight cultivation, the photosynthetic lamp at the lower end provides the light required for photosynthesis, and the exhaust valve at the upper end can discharge excess oxygen, ensuring a stable cultivation environment, avoiding contamination by miscellaneous bacteria, and meeting the light requirements of algae.

[0010] Preferably, a flushing valve is detachably connected to the lower middle part of the flushing pump, and an air inlet valve is detachably connected to the lower middle part of the heating device. The flushing valve connected to the lower end of the flushing pump can control the flow of flushing water, and the air inlet valve at the lower end of the heating device can regulate the amount of air entering. The advantage is that the flushing and heating processes can be precisely controlled through valves, ensuring both cleaning effectiveness and efficiency.

[0011] Preferably, the middle of both sides of the flushing valve is detachably connected to the middle of the air supply pipe, and the middle of both sides of the air inlet valve is detachably connected to the middle of the air supply pipe. Both the middle of both sides of the flushing valve and the air inlet valve are detachably connected to the middle of the air supply pipe. This design allows the flushing water flow and heated air to reach the area to be cleaned directly through the air supply pipe, and allows the flushing and drying paths to be combined with the air supply path, eliminating the need for additional pipelines.

[0012] Preferably, one end of the air inlet pipe is detachably connected to the middle of one side of the air filter, and one end of the air inlet pipe is detachably connected to the air filter. The air entering the heating device must be purified by the filter first to prevent impurities and bacteria in the air from entering the air delivery pipe or culture system with the airflow, thus ensuring the cleanliness of the gas during heating and drying.

[0013] Preferably, the outer wall of the aerator is detachably connected to the middle of the culture support frame, and the lower middle of the aerator is detachably connected to the outer surface of the other end of the air supply pipe. The outer wall of the aerator is detachably connected to the middle of the culture support frame to achieve stable fixation. The lower middle of the aerator is connected to the other end of the air supply pipe to receive the delivered gas, which ensures the stability of the aerator in the culture medium and avoids displacement due to the impact of the fan blade water flow.

[0014] Preferably, an air filter is detachably connected to one side of the upper end of the mixing tank, a carbon dioxide tank is detachably connected to one end of the outer surface of the delivery pipe, and a flushing assembly is detachably connected to the middle of the air supply pipe. The air filter connected to one side of the upper end of the mixing tank can purify the incoming air; the carbon dioxide tank connected to one end of the delivery pipe provides CO2 to the mixing tank, and the flushing assembly connected to the middle of the air supply pipe facilitates cleaning of the pipeline. The air intake can be kept clean through filtration.

[0015] This utility model has the following beneficial effects:

[0016] This invention discloses a carbon dioxide aeration and cultivation control device for algae. CO2 from a carbon dioxide tank enters a mixing tank via a delivery pipe, where it mixes with air purified by an air filter to form a gas of suitable concentration. This gas is then delivered to the aerator in the cultivation tank via an air supply pipe. The bubbles released by the aerator are evenly dispersed in the airflow created by the fan blades driven by a submersible motor, improving CO2 dissolution efficiency. A photosynthetic lamp on the sealed cover provides illumination, an exhaust valve discharges excess oxygen, and the base maintains stable temperature, pH, and other parameters. During cleaning, a flushing pump draws water from the water tank and flushes the air supply pipe and aerator via a flushing valve, while a heating device heats the air to dry residual water. Its advantages include improved CO2 utilization through fan blade airflow, reduced pollution and stability through multi-component collaboration, reduced maintenance costs and extended lifespan through automatic cleaning and drying, and a modular design adaptable to various scenarios.
