Description

Technical Field

[0001] The utility model belongs to the technical field of photosynthetic bacteria culture, and particularly relates to a culture device for photosynthetic bacteria. Background Art

[0002] Photosynthetic bacteria are bacteria that can carry out photosynthesis in an anoxic environment. Photosynthetic bacteria can assimilate carbon dioxide into organic matter.

[0003] Photosynthetic bacteria have very wide applications in the industry. For example, photosynthetic bacteria are used for water quality purification in aquaculture. Specifically, the growth of harmful bacteria in the water layer is inhibited by photosynthetic bacteria, thereby realizing water quality purification and protection. At the same time, the decomposition of organic matter in water and the inhibition of the growth of algae in water are realized by photosynthetic bacteria, and the effect of improving water quality is very obvious.

[0004] Therefore, photosynthetic bacteria have a very high role in green and ecological protection, and are involved in applications such as aquaculture purification and sewage treatment in the industry.

[0005] During the culture process of photosynthetic bacteria, light needs to be provided for the cultured bacteria. Currently, the mainstream methods are two. One is to install a lighting lamp that simulates light in the culture kettle, and the other is to use sunlight.

[0006] However, the disadvantages of the two are as follows: the former has too high energy consumption, and the latter is limited in that light cannot be provided at night, resulting in too low culture efficiency of bacteria.

[0007] Therefore, in the actual working process, how to be able to utilize sunlight and still be able to provide light when there is no sunlight is of great significance for improving the culture efficiency of bacteria and realizing energy-saving and environmental protection culture. Summary of the Utility Model

[0008] Based on the above background, the purpose of the utility model is to provide a culture device for photosynthetic bacteria.

[0009] To achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A culture device for photosynthetic bacteria includes a glass culture tube, and a lighting lamp bar mechanism is detachably installed on the outer side wall of the glass culture tube;

[0011] The lighting lamp bar mechanism includes an annular fixing seat detachably installed at the upper end position of the outer side wall of the glass culture tube, and a plurality of annularly distributed lighting lamp bars are fixedly assembled and connected to the annular fixing seat;

[0012] The lighting lamp bar is arranged at an interval from the glass culture tube;

[0019] Preferably, a plurality of fastening bolts are threadedly connected to the upper end of the cylinder cover, and the fastening bolts are threadedly connected to the lower end position of the outer side wall of the annular fixed seat.

[0020] Preferably, an annular sealing base is detachably installed at the bottom of the cylinder cover;

[0021] An annular through hole is formed in the annular sealing base, and the annular through hole abuts against the outer side wall of the glass culture tube.

[0022] Preferably, the annular sealing base is fastened to the bottom position of the cylinder cover through a plurality of fastening bolts.

[0023] Preferably, the culture solution stirring mechanism includes a sealing cover which is detachably installed at the top position of the glass culture tube;

[0042] Embodiment 1

[0043] As Figures 1-5 shown, a cultivation device for photosynthetic bacteria includes a glass culture tube 1 (the glass culture tube 1 is made of glass material, and a feed pipe 12 is integrally formed at the upper end of the outer side wall of the glass culture tube 1, and a discharge pipe 13 is integrally formed at the lower end of the outer side wall of the glass culture tube 1; valves are assembled and connected to both the feed pipe 12 and the discharge pipe 136. The culture solution and the photosynthetic bacteria sample are added from the feed pipe 12 and discharged from the discharge pipe 13 after cultivation). A lighting lamp bar mechanism is detachably installed on the outer side wall of the glass culture tube 1. Through the lighting lamp bar mechanism, when there is no sunlight during the cultivation process, such as at night, the lighting lamp bar mechanism provides light. And under normal sunlight conditions, natural light cultivation is realized through the light-transmitting glass culture tube 1.

[0044] Specifically, the light lamp bar mechanism includes an annular fixing base 3 detachably installed at the upper end of the outer side wall of the glass culture tube 1 (specifically, the detachable installation method is: two fastening screws 31 symmetrically arranged at an interval of 180 degrees are threadedly connected to the annular fixing base 3. Correspondingly, a threaded connection seat for threadedly connecting the fastening screw 31 is fixedly connected to the outer side wall of the glass culture tube 1), and a plurality of annularly distributed light lamp bars 4 are fixedly assembled and connected to the annular fixing base 3. Among them, the light lamp bar 4 is a conventional light lamp for cultivating photosynthetic bacteria disclosed in the prior art, in the shape of a growth rod. The same as the existing method, the light lamp bar 4 is electrically connected to an external power supply.

[0045] Moreover, the light lamp bar 4 and the glass culture tube 1 are arranged at an interval.

[0046] During the working process, especially when there is no light at night, the light lamp bar 4 is turned on to provide the light required for the cultivation and growth of photosynthetic bacteria by the light lamp bar 4.

[0047] To increase the lighting effect, the above light lamp bar 4 mechanism further includes a sealing cover assembly, and the sealing cover assembly includes a cylinder cover 5, and the cylinder cover 5 is fixedly installed at the lower end position of the outer side wall of the annular fixing base 3; the light lamp bar 4 is located inside the cylinder cover 5.

[0048] Specifically, a plurality of fastening bolts are threadedly connected to the upper end of the cylinder cover 5, and the fastening bolts are threadedly connected to the lower end position of the outer side wall of the annular fixing base 3. The bottom of the cylinder cover 5 is detachably installed with an annular sealing base 6; an annular through hole is opened on the annular sealing base 6, and the annular through hole abuts against the outer side wall of the glass culture tube 1, and the annular sealing base 6 is fastened to the bottom position of the cylinder cover 5 through a plurality of fastening bolts.

[0049] During the working process, the cylinder cover 5 is sleeved from the bottom of the glass culture tube 1, and the upper end of the cylinder cover 5 is fastened to the side wall of the annular fixing base 3. At this time, under the action of the light lamp bar 4 and the light blocking of the cylinder cover 5, the lighting effect is increased, and thus the efficiency of light cultivation is improved.

[0050] After the cylinder cover 5 is installed, when the annular sealing base 6 is sleeved from the bottom of the glass culture tube 1 and installed, the lighting intensity inside the cylinder cover 5 is further maintained.

[0051] When there is natural light, the cylinder sleeve is disassembled to realize cultivation using natural light.

[0052] By the above method, photosynthetic bacteria are cultivated in an energy-saving and environment-friendly manner, and the cultivation energy consumption and cost of the above method are low, greatly improving the cultivation efficiency.

[0053] Embodiment 2

[0054] Such as Figures 1-5As shown in the figure, on the basis of the structure of Embodiment 1, the culture device for photosynthetic bacteria further includes a culture solution stirring mechanism 2.

[0055] The culture solution stirring mechanism 2 includes a sealing cover 11 detachably installed at the top of the glass culture tube 1; specifically, several screws penetrating the sealing cover 11 are fixedly connected to the top of the glass culture tube 1, and nuts are fastened to the screws.

[0056] At the same time, a stirring motor 21 is fixedly installed on the sealing cover 11, and a long stirring shaft rotatably connected to the sealing cover 11 is installed on the stirring motor 21 (in the same way as the existing method, the output shaft of the stirring motor 21 is fixedly installed on the long stirring shaft, such as by means of a coupling). Since bacteria have cell walls, during the culture process, in order to improve the culture efficiency and stir the material system while avoiding breaking the cell walls of bacteria during the stirring process and causing the death of bacteria, a number of spring flow stirring components are fixedly assembled and connected to the long stirring shaft.

[0057] Specifically, the spring flow stirring component includes a spring 22 fixedly connected to the long stirring shaft, and a flow stirring ball is fixedly connected to the outer end of the spring 22; the flow stirring ball is a steel ball 23 with a middle hole inside.

[0058] During the stirring process, the rotating spring 22 flow stirring component fully stirs the entire system. During the stirring process, since there is no shear force between the spherical structure and the culture system, it is possible to avoid damaging the cell walls of bacteria by the traditional stirring paddle stirring method.

[0059] During the rotation process, due to the structural design of the spring 22, during the rotation process, the swaying spring 22 drives the steel ball 23 to continuously swing irregularly. By the irregular swing, the stirring effect on the material system is increased, ensuring that in the material system, from the top to the bottom of the material layer, the material system can fully flow and exchange, and the distribution effect of the material system during the culture process is increased.

[0060] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
