Description

Technical Field

[0001] The utility model belongs to the technical field of microalgae bioreactors, and particularly relates to a microalgae bioreactor for treating aquaculture tail water with integrated bacteria and algae culture. Background Technique

[0002] A microalgae bioreactor for treating aquaculture tail water with integrated bacteria and algae culture refers to a bioreactor that combines the work of microorganisms (bacteria) and microalgae, and is used to treat the tail water generated by aquaculture (i.e., the wastewater discharged during the aquaculture process). This reactor can effectively remove nutrients (such as nitrogen, phosphorus, etc.) in the water, and at the same time, these nutrients can be recycled to cultivate microalgae to produce valuable by-products, such as biofuels, feed additives, etc.

[0003] Traditional microalgae bioreactors for treating aquaculture tail water often cannot ensure that microalgae receive uniform light. Especially in an indoor environment, changes in light intensity and direction may lead to uneven growth of microalgae, thereby affecting the effect of tail water treatment and the yield of microalgae.

[0004] In addition, in an outdoor environment, due to the change of the sun's position, microalgae may not be able to continuously obtain the optimal light angle, which also limits the growth rate and photosynthesis efficiency of microalgae. Therefore, a reactor design that can adapt to different light conditions and enable microalgae to fully contact light is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a microalgae bioreactor for treating aquaculture tail water with integrated bacteria and algae culture, so as to solve the technical problem that changes in light intensity and direction may lead to uneven growth of microalgae, thereby affecting the effect of tail water treatment and the yield of microalgae proposed in the background technique.

A bottom plate is provided at the lower end of the mounting frame, and a reactor body is rotatably mounted on the bottom plate. An installation groove is opened inside the reactor body, and a lighting lamp is installed in the installation groove. The lighting lamp is fixedly connected to the upper end of the mounting frame, and the mounting frame is rotatably mounted on the bottom frame.

[0010] Preferably, a limiting ring is provided at the upper end of the mounting frame, and the ring frame provided at the upper end of the reactor body fits against the upper side of the limiting ring.

[0011] Preferably, the lower side of the mounting frame is rotatably connected to the bottom frame through a second rotating rod.

[0012] Preferably, a fixing plate is provided on one side of the bottom frame. One end of the second rotating rod passes through the fixing plate and is connected to a ratchet wheel, and the ratchet wheel meshes with a pawl rotatably provided on the fixing plate. One side of the pawl is in contact with a spring piece rotatably mounted on the fixing plate.

[0013] Preferably, when the second rotating rod rotates, the mounting frame drives the reactor body to be in an inclined state.

[0034] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a microalgae bioreactor for treating aquaculture tail water with integrated bacteria and algae in combination with the accompanying drawings.

[0035] As Figures 1 to 8 shown, a microalgae bioreactor for treating aquaculture tail water with integrated bacteria and algae of the present utility model includes a mounting frame 1. A bottom plate 2 is provided at the lower end of the mounting frame 1. A reactor body 6 is rotatably mounted on the bottom plate 2. Therefore, an annular groove 3 is formed on the bottom plate 2, and the reactor body 6 is rotatably connected to the bottom plate 2 through the annular groove 3.

[0036] Among them, a gear ring 7 is arranged on the lower side of the reactor body 6. The gear ring 7 meshes with a third gear 11 rotatably arranged at the rear side of the mounting frame 1. And at the upper end of the rotating shaft of the third gear 11, a second gear 10 is connected. A first rotating rod 8 is rotatably arranged at the rear side of the mounting frame 1, and a first gear 9 is connected to the first rotating rod 8. By driving the first rotating rod 8 with a motor, when the first rotating rod 8 drives the first gear 9 to rotate, through the meshing of the first gear 9 and the second gear 10, the second gear 10 is rotated, and further the second gear 10 drives the third gear 11 to mesh, so as to achieve the purpose of driving the reactor body 6 to rotate with the gear ring 7.

[0037] Since an installation groove 17 is formed inside the reactor body 6, and a lighting lamp 18 is installed in the installation groove 17. The lighting lamp 18 is fixedly connected to the upper end of the mounting frame 1. When the reactor body 6 rotates, the lighting lamp 18 remains stationary, and the reactor body 6 rotates around the lighting lamp 18, enabling the microalgae to receive sufficient light. The lighting lamp 18 can be used when the indoor lighting where the reactor body 6 is located is insufficient.

[0038] As Figure 3 shown, a limiting ring 4 is arranged at the upper end of the mounting frame 1. The ring frame 19 arranged at the upper end of the reactor body 6 fits with the upper side of the limiting ring 4, and the stability of the reactor body 6 is improved by using the limiting ring 4.

[0039] Considering that when the outdoor light is sufficient, the reactor body 6 can be placed outdoors for photosynthesis. The mounting frame 1 is rotatably installed on the bottom frame 24. At the same time, the lower side of the mounting frame 1 is rotatably connected to the bottom frame 24 through a second rotating rod 12. When the second rotating rod 12 rotates, the reactor body 6 can be tilted (as Figure 2 shown), facilitating sunlight to irradiate the reactor body 6.

[0040] To improve the stability of the second rotating rod 12, a fixing plate 13 is arranged on one side of the bottom frame 24. One end of the second rotating rod 12 penetrates through the fixing plate 13 and is connected to a ratchet 14. The ratchet 14 meshes with a pawl 15 rotatably arranged on the fixing plate 13. One side of the pawl 15 is in contact with a spring piece 16 rotatably installed on the fixing plate 13. By using the meshing of the ratchet 14 and the pawl 15, the second rotating rod 12 drives the mounting frame 1 to rotate stably.

[0041] Further, a first support rod 20 is hinged on one side of the bottom frame 24. A second support rod 21 is slidably connected inside the first support rod 20. The second support rod 21 is fixed by a bolt 22. Since a clamping plate 23 is arranged at the upper end of the second support rod 21, the clamping plate 23 is in clamping fit with a clamping groove 5 formed at the upper end of the mounting frame 1. By sliding the second support rod 21 inside the first support rod 20 to adjust the support position, the mounting frame 1 is always kept stable.

[0042] Working principle of a microalgae bioreactor for treating the tail water of integrated bacteria and algae culture: When indoors, by engaging the gear ring 7 with the third gear 11, the gear ring 7 can drive the reactor body 6 to rotate, so that the microalgae in the reactor body 6 indoors can fully contact the lighting lamp 18, improving photosynthesis; When outdoors, when the second rotating rod 12 drives the mounting frame 1 to rotate, the reactor body 6 is tilted, enabling the microalgae in the reactor body 6 outdoors to fully carry out photosynthesis. At the same time, combined with the self-rotation of the reactor body 6, all parts of the microalgae in the reactor body 6 can fully contact sunlight.

[0043] It can be understood that the present utility model is described through some embodiments. As is known to those skilled in the art, without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
