Description

Technical Field

[0001] The utility model relates to the technical field of desert cyanobacteria cultivation, and more particularly to a desert cyanobacteria cultivation device for field use. Background Art

[0002] Desert cyanobacteria are a class of prokaryotic microorganisms capable of oxygenic photosynthesis, some of which have biological nitrogen fixation activity. They are pioneer colonizers in arid habitats. They play an important role in sand fixation and soil formation, topsoil water capture and retention, the biogeochemical cycle of nutrients, and the development and succession of plant communities. Their potential value in areas such as desert degraded land restoration has attracted much attention. The use of artificial biological soil crusts to control desertified land is an emerging green and environmentally friendly sand fixation technology in recent years and is currently a hot topic in research on ecological restoration in sandy areas. A sufficient amount of desert cyanobacteria is the basis for large-scale desertification restoration using this technology. Therefore, the large-scale cultivation of desert cyanobacteria is an important prerequisite and guarantee for the promotion and application of this technology.

[0003] Traditional large-scale cultivation of desert cyanobacteria mainly uses open culture tanks. Although this culture device can achieve large-scale cultivation, it still has some technical problems:

[0004] 1. The biomass of desert cyanobacteria cultivated in open culture tanks is generally low and easily contaminated by other microorganisms; at the same time, the structure is complex and the cost is generally high.

[0005] 2. During the cultivation process, a large number of desert cyanobacteria adhere to the wall and sink to the bottom, which limits the growth of desert cyanobacteria and reduces the cultivation quality.

[0006] Therefore, how to provide a culture device with a simple structure that can effectively prevent desert cyanobacteria from adhering to the wall and sinking to the bottom during the culture process and improve the culture quality is an urgent problem that needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the present invention provides a device for cultivating desert cyanobacteria for outdoor use, aiming to solve the above technical problems.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A device for cultivating desert cyanobacteria for outdoor use, comprising:

[0010] The bottom of the tank body is a conical structure, and the top of the tank body is detachably connected to the cover body; the inner wall of the tank body is slidably connected to the hollow mesh plate;

[0011] The lifting mechanism includes a driving part and a connecting part. The driving part is installed on the bottom wall of the cover body. One end of the connecting part is detachably connected to the telescopic end of the driving part, and the other end is fixedly connected to the hollow mesh plate.

[0012] Through the above technical solution, the utility model provides a desert cyanobacteria cultivation device for outdoor use, with a detachable cover design, which is convenient for later collection, cleaning and maintenance; the setting of the hollow mesh plate provides a space for cyanobacteria to attach and grow, which can increase the attachment area of ​​cyanobacteria per unit volume, thereby improving the cultivation efficiency; the hollow design allows water to flow freely up and down the mesh plate, which can promote the exchange of nutrients and oxygen, and at the same time, it also helps to maintain the concentration of suspended matter in the water body; the hollow mesh plate is driven up and down along the inner wall of the tank body by the lifting mechanism, which can increase the fluidity of the water body. This disturbance helps to prevent cyanobacteria cells from depositing and adhering to the inner wall of the tank body, effectively promoting the growth of cyanobacteria and improving the cultivation quality.

[0013] Preferably, in the above-mentioned field cyanobacteria cultivation device, a guide rail is provided on the inner sidewall of the tank, and the connecting portion is slidably connected to the guide rail. The provision of the guide rail provides a guide for the connecting portion to drive the hollow mesh plate to move up and down, thereby making the driving portion more stable when driving the hollow mesh plate to move up and down.

[0014] Preferably, in the aforementioned field-use desert cyanobacteria cultivation device, the connecting portion includes a connecting rod, a roller, and a guide wheel. One end of the connecting rod is fastened to the telescopic end of the driving portion via a bolt. The roller is fixed to the upper surface of the hollow mesh plate via a bracket. The guide wheel is fixed to the lower surface of the hollow mesh plate via a bracket and is slidably connected to the guide rail. The provision of the roller can effectively reduce friction during movement, and the cooperation between the guide wheel and the guide rail can achieve vertical guidance.

[0015] Preferably, in the above-mentioned field-use desert cyanobacteria cultivation device, the number of the rollers and the guide wheels is multiple, and the multiple rollers and the multiple guide wheels are staggeredly arranged on the upper edge and the lower edge of the hollow mesh plate, respectively, to increase the stability of the hollow mesh plate during the lifting process.

[0016] Preferably, in the above-mentioned field-use desert cyanobacteria cultivation device, the tank body includes an integrally formed cylindrical section and a conical section. A suspension zone is formed within the cylindrical section, and the cover is fixed to its top by bolts. The hollow mesh plate is slidably connected to the inner side of the cylindrical section. The top diameter of the conical section is larger than the bottom diameter. The bottom of the conical section forms a sedimentation zone. A centrifugal pump is installed on the bottom wall of the conical section. The outlet end of the centrifugal pump is connected to a first pipeline. The other end of the first pipeline extends into the cylindrical section and passes through the center hole of the hollow mesh plate. This structural arrangement forms a sedimentation zone at the bottom of the conical section. When the cyanobacteria settle and accumulate to a certain amount, the centrifugal pump is started to suck the cyanobacteria settled in the sedimentation zone into the centrifugal pump and re-pump the cyanobacteria into the suspension zone through the first pipeline, thereby solving the technical problem of cyanobacteria settling and affecting its growth. The centrifugal pump adopts a low-speed centrifugal pump, which can effectively prevent damage to the cyanobacteria cell structure. At the same time, the hollow mesh plate provides effective support for the first pipeline.

[0017] Preferably, in the aforementioned field-use desert cyanobacteria cultivation device, an air compressor is mounted on the outer wall of the conical section. The outlet of the air compressor is connected to an air pipe, the other end of which extends into the interior of the conical section. The installation of the air compressor not only increases the fluidity of the water, providing more uniform lighting and temperature conditions for the cyanobacteria and reducing adherence to the wall, but also provides air to the interior of the tank, increasing dissolved oxygen in the water and promoting photosynthesis and growth of the cyanobacteria.

[0018] Preferably, in the aforementioned field-use desert cyanobacteria cultivation device, the sidewall of the conical section includes a solution exchange port and an algae liquid discharge port. Filters are installed at both the solution exchange port and the algae liquid discharge port. These two functions operate independently. It should be noted that while the solutions within the tank are mixed, the nutrient solution is replaced primarily to maintain its freshness and an appropriate nutrient ratio to support the continued growth of the cyanobacteria (this can be accomplished by draining some of the nutrient solution and then replenishing it, repeating this process several times to gradually dilute and drain the old nutrient solution and minimize algae liquid loss). The algae liquid is discharged at the end of the cultivation cycle to harvest the cyanobacterial cells.

[0019] Preferably, the above-mentioned field-use desert cyanobacteria cultivation device further includes a lighting assembly mounted on the bottom wall of the cover. The lighting assembly can provide controllable lighting conditions, simulate the lighting changes in the natural environment, and promote the photosynthesis of cyanobacteria.

[0020] Preferably, the above-mentioned field-use desert cyanobacteria cultivation device further includes a temperature control assembly mounted on the bottom wall of the cover. The temperature control assembly can timely adjust and maintain a suitable temperature, providing an optimal environment for the growth of cyanobacteria.

[0021] Preferably, in the above-mentioned field-use desert cyanobacteria cultivation device, the tank is fixed to a frame, the bottom of the frame is equipped with running wheels, and the frame is equipped with a vertical pole, and the top of the vertical pole is equipped with a solar panel. The solar panel provides power for the above-mentioned electrical components.

[0022] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a device for cultivating desert cyanobacteria for outdoor use, which has the following beneficial effects:

[0023] 1. The utility model has a simple structure and can effectively prevent cyanobacteria from adhering to the wall and settling, thereby ensuring the cultivation efficiency of cyanobacteria.

[0024] 2. The utility model allows water to flow freely up and down the mesh plate through the setting of the hollow mesh plate, which can promote the exchange of nutrients and oxygen; at the same time, it also helps to maintain the concentration of suspended matter in the water.

[0025] 3. The setting of the air compressor of the utility model can achieve the disturbance of the water inside the tank. Combined with the structural setting of the lighting component and the temperature control component, it promotes the photosynthesis and growth of cyanobacteria and improves the cultivation quality of cyanobacteria.
