Description

Technical Field

[0001] The invention relates to the technical field of algae cultivation, and in particular to an algae ventilation cultivation acceleration device. Background Art

[0002] Propagation of Chlorella (also known as green algae) usually refers to the process of increasing its growth in the laboratory or industry. It generally includes the following steps: first, prepare a culture medium suitable for the growth of Chlorella, obtain an appropriate amount of Chlorella cells from the original culture, and then transfer them to a new culture medium; during the culture process, it is necessary to provide appropriate light intensity and light cycle (usually 12 hours of light and 12 hours of darkness), and the culture temperature is generally preferably 20-25 degrees Celsius; through appropriate stirring or ventilation, sufficient carbon dioxide is provided to promote the growth of Chlorella; when the density of Chlorella cells increases to a certain level, it is necessary to subculture, the purpose of which is to separate the Chlorella into a new culture medium to avoid excessive cell density leading to competition and nutrient depletion. Most of the separated Chlorella can be normally put into the breeding pond, thereby cultivating a large number of beneficial algae microorganisms and accelerating the growth of aquatic fish and shrimp; Chinese Patent No. CN106010939B discloses an algae cultivation device, including an incubator, which includes an outer box body, an inner box body, and a box cover. The box cover can cover the outer box body and the inner box body. A sealing structure that can seal the inner box body is provided between the box cover and the inner box body. A cool white fluorescent lamp and an ultraviolet lamp are fixed to the inner side wall and inner bottom surface of the outer box body. A plurality of fixing rods are vertically fixed to the bottom surface of the inner box body. The lengths of the fixing rods are all different. A transparent glass cover is fixed to the upper end of the fixing rod. The cool white fluorescent lamp is provided in the transparent glass cover. Although this device has the advantages of accurately controlling the growth of algae and increasing the yield of algae, when adding nutrient powder to improve the cultivation efficiency, the device often requires personnel to manually pour the nutrient powder directly, which not only reduces the utilization rate of the nutrient powder, but also causes the algae cells to be damaged due to the sudden change in the environment. In view of this, the present invention proposes an algae aeration culture acceleration device to remedy and improve the shortcomings of the prior art. Summary of the Invention

[0012] Compared with the prior art, the present invention has the following beneficial effects: The feeding mechanism provided in the present invention can utilize the continuous rotation of the reciprocating screw and cooperate with the position limiting of the carrier by the feeding and moving platform to prompt the moving platform to carry the carrier and perform horizontal reciprocating movement along the reciprocating screw, thereby linking the baffle plate and the storage tube to repeatedly move back and forth between the feed hopper and the injection hole, so that the storage tube intermittently transfers the powder injected into its inner cavity to the inner cavity of the culture cylinder through the injection hole in an equal amount, which is beneficial to ensure the balanced acquisition of nutrients by algae in the colony, avoid the over-reproduction of some individuals due to excessive nutrition, or the decline due to insufficient nutrition, thereby improving the overall culture density and biomass yield; The present invention can also utilize the feeding mechanism provided, and the push frame to follow the movement of the moving platform, so that the push rod carries the piston block and moves horizontally back and forth along the air supply cylinder, and cooperates with the one-way valve to block the culture liquid in the culture cylinder cavity, so that the external air is sequentially passed through the vent hole → air supply cylinder → exhaust pipe → diverter pipe → aeration head → culture cylinder cavity, thereby aerating the culture liquid in the culture cylinder cavity, which not only makes the nutrient powder more fully mixed, but also creates a flowing environment and sufficient oxygen; The ventilation mechanism of the present invention can utilize the continuous rotation of the rotating shaft and the rotating shaft to make the scraper and the fan blade rotate accordingly. The rotation of the fan blade allows the external air to be filtered by the filter and transported toward the inner cavity of the culture cylinder.
