  The present invention relates to a plant culture apparatus, and more particularly to an algae culture apparatus.

  The system for culturing algae can be easily divided into an open culture system and a closed culture system according to the culture environment. Considering the cost, the current algae culture is mainly an open aquaculture system. However, in recent years, it has become difficult to adjust the outdoor culture environment due to severe climate change and significant environmental pollution. For example, once heavy rain falls, the pH value of the culture solution may change, and further, pollutants in the atmosphere are carried into the outdoor aquaculture pond, which rapidly changes the culture environment, thus algae. Will kill or affect the quality of algae.

  Since the influence of factors such as drastic changes in climate and environmental pollution on the closed-type aquaculture system is relatively small, some contractors have changed to the closed-type aquaculture system and cultured algae. However, the closed-type aquaculture system uses transparent and sterilizable materials such as glass or acrylic as a culture tank, and keeps the culture fluid in a circulating flow so that the effects of growth on algal growth or death can be reduced. Avoiding the factors, the cost of the closed aquaculture system was much higher than the open aquaculture system. Next, the volume of aquaculture tanks made of materials such as glass or acrylic has certain limitations, so the production volume of a closed aquaculture system cannot match that of an open aquaculture system.

Further, the fluid inlet 32 is not in contact with the lower lid assembly 20, and the fluid inlet 32 and the opening of the second fluid passage 21 are at a certain distance.

  In the present embodiment, the algae culture device 1 further includes an air supply device 60 (FIG. 5) connected to the first fluid passage 11 and the second fluid passage 21, respectively, through which the gas is supplied to the first fluid passage 11 or Control is performed so as to enter the culture space C from the second fluid passage 21.

  Referring to FIG. 2, when the algae culture apparatus 1 is in a culture state, green algae and its culture liquid (hereinafter referred to as “alga liquid L”) are transferred from the culture liquid passage 12 to the inside of the plastic bag 50 (culture space C). The gas can be injected and controlled by the air supply device 60 and the pressure regulator 70 so that the gas is blown from the second fluid passage 21, and the flow direction of the gas is as indicated by the solid line arrow. In this case, the second fluid passage 21 serves as an intake passage. After the gas enters the culture space C, the fluid inlet 32 of the fluid conduit 30 corresponds to the second fluid passage 21, so that the gas enters the fluid conduit 30 directly from the fluid inlet 32 and simultaneously the algal fluid in the culture space C L can enter the fluid conduit 30 and the flow direction of the algal fluid L is as shown by the dotted arrows. Next, the gas and the algal liquid L further flow out from the fluid outlet 33 close to the upper lid 10, and the algal liquid L is circulated and flowed through the fluid outlet 33, whereby the precipitation prevention effect of the algal liquid L can be achieved. Preferably, the fluid conduit 30 further includes an inner lid 34 provided above the fluid outlet 33 to ensure that the algae liquid L can flow out of the fluid outlet 33 so that the algae liquid L is at the top end 31 of the fluid conduit 30. Therefore, the circulation effect can be prevented from being lowered. Further, since the gas can be discharged from the first fluid passage 11 after being discharged from the fluid outlet 33, it becomes an exhaust passage when the first fluid passage 11 is in the culture state.

  Preferably, the upper lid 10 of the present embodiment can further include at least one parameter sensor element 13, one end of which is accommodated in the culture space C, and one end of the parameter sensor element 13 can contact the algal fluid L. Through the installation of the parameter sensor element 13, environmental parameters such as pH or temperature of the algal liquid L are detected. When the parameter sensor element 13 of the present embodiment is a pH value and temperature detection element, the pH value and temperature of the culture solution are adjusted in real time by detecting the pH value and temperature of the algal fluid L, and the green algae Can be grown in a stable environment. In another embodiment, in order to directly adjust the temperature of the culture solution or the algal solution L, a warmer or a desuperheater can be provided, which is not limited in the present invention.

  When the density of green algae in the algae liquid L reaches saturation, it can be collected or transferred to another algae culture apparatus 1a (FIG. 5) having a relatively large volume for culturing. Referring to FIG. 3, when the algae culture device 1 is in the collection state, it can be controlled to blow gas from the first fluid passage 11 into the culture space C through the air supply device 60. In this case, the first fluid passage 11 is inhaled. It becomes a passage. Further, the flow direction of the gas is as indicated by the solid arrow, which helps the algal liquid L in the culture space C to be discharged from the second fluid passage 21, and in this case, the second fluid passage 21 becomes the liquid passage. Gas can also enter the fluid conduit 30 via the fluid outlet 33, which can help expel the algal fluid L in the fluid conduit 30 from the fluid inlet 32.

  The point to be mentioned here is that the fluid inlet 32 and the fluid outlet 33 serve as a basis for naming the direction of fluid movement when the algae culture apparatus 1 is in the culture state, and the present invention is because the fluid inlet 32 is only the inlet. It is not limited that the fluid outlet 33 is used only for the outlet. As described above, when the algae culture apparatus 1 is in the collection state, the fluid inlet 32 can also be a gas outlet, and the fluid outlet 33 can be a gas inlet.

  Moreover, the 2nd fluid channel | path 21 can be connected with the container of the collection algae liquid L, or can mutually communicate with the culture solution channel | path 12a of another algae culture apparatus 1a. As shown in FIG. 5, FIG. 5 is a schematic view showing an algae culture system according to an embodiment of the present invention. In the present embodiment, the algae culture system C includes the algae culture apparatus 1 of the above embodiment and another algae culture apparatus 1a. Since the volume of the algae culture apparatus 1a is larger than the volume of the algae culture apparatus 1, and the structure and connection relation of other components can be referred to the above-described embodiment, the description thereof is omitted here. For example, the algae culture apparatus 1 can be a cylinder having a diameter of 50 cm and a height of 100 cm, and the algae culture apparatus 1a can be a cylinder having a diameter of 100 cm and a height of 200 cm. In other embodiments, in addition to the algae culture devices 1 and 1a, the algae culture device 1a can be further connected to an algae culture device having a diameter of 200 cm and a height of 300 cm, which is not limited in the present invention.

  As described above, the second fluid passage 21 of the algae culture device 1 and the culture fluid passage 12a of the algae culture device 1a communicate with each other. As a result, when the green algae are first cultured in the algae culture apparatus 1 having a relatively small volume and cultured to a stage where the algae liquid can be collected, the green algae are discharged through the second fluid passage 21 and passed through the culture fluid passage 12a. The algae liquid L cultured in the process and the newly arranged culture liquid are injected into the culture space C of the algae culture apparatus 1a to continue the culture. It is called expansion culture in the technical field of the present invention.
