Description

Technical Field

[0001] This utility model relates to the field of spirulina cultivation technology, and in particular to a pollution-resistant spirulina cultivation device with water inlet sterilization. Background Technology

[0002] Spirulina, a blue-green algae rich in protein and various nutrients, is widely used in food, feed, and medicine. However, existing spirulina cultivation devices generally lack effective water purification functions. During the cultivation process, the culture medium for spirulina growth accumulates a large number of pollutants, such as suspended solids, silt, fatty acids, proteins, and other organic matter, as well as inorganic substances such as nitrates and phosphates. At the same time, water sources, air, cultivation containers, seed algae, and microorganisms such as bacteria, fungi, and viruses introduced during the operation process also continuously accumulate in the culture medium.

[0003] These pollutants and pathogens are extremely harmful. On the one hand, they consume the nutrients needed for spirulina growth and compete with spirulina for survival resources. For example, common bacteria such as Escherichia coli and Pseudomonas aeruginosa will consume large amounts of nutrients in the culture medium, resulting in insufficient nutrition for spirulina and slowing down its growth rate. On the other hand, some microorganisms produce harmful substances, such as enterotoxins and cytotoxins produced by bacteria, and fungi that invade cells, destroy cell structure, and promote the production of intracellular toxins. These toxins seriously affect the physiological activity of spirulina, leading to a decrease in its reproductive capacity. A large number of pathogens and pollutants will also change the physicochemical properties of the culture medium, causing indicators such as pH and dissolved oxygen to deviate from the range suitable for spirulina growth, further inhibiting its reproduction. All these factors combined ultimately lead to a significant reduction in spirulina cultivation efficiency, seriously hindering the development of the spirulina industry. Utility Model Content

[0004] In order to overcome the problem that existing spirulina cultivation devices lack water purification functions, resulting in the generation of a large number of pollutants and bacteria during spirulina cultivation, which seriously affect the reproduction of spirulina and thus reduce the efficiency of spirulina cultivation, this utility model provides a pollution-proof spirulina cultivation device with water inlet sterilization.

[0005] The technical solution is as follows: a pollution-proof spirulina cultivation device with water inlet sterilization, including a transparent culture tank, a carbon dioxide supply component, a transparent vent cover, and a water inlet filter component; the water inlet filter component is installed at the bottom of the transparent culture tank; a carbon dioxide supply component is installed on one side of the water inlet filter component; a transparent vent cover is installed at the upper port of the transparent culture tank, and the transparent vent cover is connected to the transparent culture tank in a slot.

[0006] Furthermore, a water inlet trough is provided at the bottom of the transparent culture tank, and the water inlet trough is integrally formed with the transparent culture tank; a filter plug is provided inside the water inlet trough, and the filter plug is threadedly sealed to the water inlet trough.

[0007] Furthermore, the filter plug is equipped with a PES bacteria filter element inside, and the PES bacteria filter element is fixedly connected to the inner wall of the filter plug.

[0008] Furthermore, a filter element sealing ring is provided on the inner wall of the upper port of the water inlet tank, and the filter element sealing ring is sealed and connected to the PES bacteria filter element slot, and the filter element sealing ring is integrally formed with the inner wall of the water inlet tank.

[0009] Furthermore, the inner wall of the transparent culture vessel is provided with a venting pipe support, and the venting pipe support is bolted to the inner wall of the transparent culture vessel.

[0010] Furthermore, an aeration pipe is provided at one end of the ventilator support, and the aeration pipe is fixedly connected to the ventilator support.

[0011] Furthermore, a gas filter element is installed inside the aeration pipe, and the gas filter element is filled inside the aeration pipe; ventilation holes are provided at both the upper and lower ends of the aeration pipe.

[0012] The beneficial effects are as follows: This utility model achieves the filtration of bacteria or impurities in the water supply through a combination of a replaceable filter plug and a PES bacteria filter cartridge inside the water inlet tank. During the cultivation of spirulina, contaminated water sources may introduce harmful microorganisms. These microorganisms compete with spirulina for nutrients and may even release harmful metabolic products. Under suitable water quality conditions, spirulina can more efficiently absorb nutrients from the water and perform photosynthesis, thereby increasing the healthy reproduction rate of spirulina. The filter plug, as a preliminary filtration device, has a staggered grid structure at its lower end, which can intercept larger particles of impurities such as sand and leaf fragments, preventing these impurities from entering subsequent filtration stages and avoiding clogging of the PE bacteria filter cartridge. When water flows through the filter plug, some larger suspended particles are also filtered out. Floating matter is directly blocked by the screen. As the usage time increases, when the filter block traps too many impurities and affects the water flow, its easy-to-replace characteristics allow for quick disassembly, cleaning, or replacement with a new filter block, ensuring the continuous effectiveness of the initial filtration stage. The pore size of the PES bacterial filter cartridge allows the culture medium to pass through, effectively intercepting viruses, bacteria, and other microorganisms, as well as tiny impurities in the water supply. For example, the size of common E. coli is much larger than the pore size of the PES bacterial filter cartridge, and the bacteria are firmly blocked on the surface of the filter cartridge when the water flows through it. Smaller viruses, such as bacteriophages, cannot penetrate the precise pore structure of the filter cartridge. In addition, some impurities with a particle size of micron, such as clay particles and rust, are also effectively intercepted by the filter cartridge, ensuring that the filtered water meets a high standard of cleanliness.

[0013] By setting up a carbon dioxide supply component, the carbon dioxide supply component is connected to an external carbon dioxide supply pipeline. After filtering out impurities in the carbon dioxide using a gas filter cartridge, the carbon dioxide is continuously flushed into the spirulina culture medium, thereby improving the reproduction efficiency of spirulina.

[0023] The bottom of the transparent culture tank 1 is provided with a water inlet trough 401, and the water inlet trough 401 is integrally formed with the transparent culture tank 1; the inside of the water inlet trough 401 is provided with a filter plug 402, and the filter plug 402 is threadedly sealed to the water inlet trough 401.

[0024] The filter plug 402 is equipped with a PES bacteria filter element 403, and the PES bacteria filter element 403 is fixedly connected to the inner wall of the filter plug 402.

[0026] The inner wall of the transparent culture tank 1 is provided with a venting pipe support 201, and the venting pipe support 201 is bolted to the inner wall of the transparent culture tank 1.

[0027] The system utilizes a combination of easily replaceable filter plug 402 and PES bacteria filter cartridge 403 inside the water inlet tank 401 to filter bacteria or impurities from the water supply. During spirulina cultivation, contaminated water sources may introduce harmful microorganisms that compete with spirulina for nutrients and may even release harmful metabolic products. Under suitable water quality conditions, spirulina can more efficiently absorb nutrients from the water and perform photosynthesis, thereby increasing the healthy reproduction rate of spirulina. Filter plug 402, as a preliminary filtration device, has a staggered grid structure at its lower end to intercept larger particles such as sand and leaf fragments, preventing these impurities from entering subsequent filtration stages and clogging the PES bacteria filter cartridge 403. As water flows through filter plug 402, some larger suspended solids... The impurities are directly blocked by the screen. As the usage time increases, when the impurities intercepted by the filter plug 402 become too large and affect the water flow, the filter plug 402 can be quickly disassembled and cleaned or replaced due to its easy replacement characteristics, ensuring the continuous effectiveness of the initial filtration stage. The pore size of the PES bacterial filter cartridge 403 allows the culture medium to pass through, effectively intercepting viruses, bacteria and other microorganisms and tiny impurities in the water supply. For example, the size of common E. coli is much larger than the pore size of the PES bacterial filter cartridge 403, and the bacteria will be firmly blocked on the surface of the filter cartridge when the water flows through. Smaller viruses such as bacteriophages cannot penetrate the precise pore structure of the filter cartridge. In addition, some impurities such as clay particles and rust with a particle size of micron will also be effectively intercepted by the filter cartridge, ensuring that the filtered water quality reaches a high standard of cleanliness.
