Abstract
The utility model discloses a laboratory microalgae cultivation reactor. The upper end of the main body of the laboratory microalgae cultivation reactor is cylindrical, and the lower end of the main body is cone-shaped; a light insulation flow guide cylinder of which the front part is opened is arranged in the main body and is fixedly connected with the main body through two side plates; a top cover is arranged at the upper end of the main body, a vent pipe and a sampling pipe are inserted into the top cover, and an air outlet is formed in the top cover. The laboratory microalgae cultivation reactor disclosed by the utility model can save space, is convenient in sampling, has an excellent airlift circulation effect, and can realize excellent liquid reflux; compared with the traditional airlift circulation device, the flow guide cylinder is opened to adapt to changes of the liquid level of a culture solution, so that full-illumination cultivation can be realized, and the cultivation efficiency can be improved. By adopting the laboratory microalgae cultivation reactor disclosed by the utility model, through the light insulation flow guide cylinder matching with the airlift circulation, the microalgae are always kept in a rapid bright and dark alternating environment, and even under full-light cultivation, the growth of the microalgae can not be inhibited. The laboratory microalgae cultivation reactor disclosed by the utility model is suitable for use in laboratories, and can be cleaned and disassembled conveniently.
Description
Technical field
The utility model relates to the Pilot Unit of the micro-algae of laboratory culture.
Background technology
At present, the mode that use for laboratory liquid nutrient medium is cultivated micro-algae is on a small scale mainly shake-flask culture, bubbling style culturing bottle is cultivated or cultivated post and cultivates, but all because there being obvious defect to limit the application in experiment.Shake-flask culture can not pass into CO well
2deng gas; Culturing bottle is cultivated and is sunk to the bottom because liquid fluidity deficiency easily causes frustule; Cultivate because pillar length reaches more than 1 meter and cultivate post, take up room large, be not suitable for carrying out the cultivation of little space.For the micro-algae that is not suitable for full exposure cultivation, the conventional culture apparatus in existing laboratory is difficult to directly be suitable for, and cultivate by light dark period is set conventionally in laboratory, but this can cause again the biomass accumulation rate reduction of micro-algae.In addition, the micro algae growth cycle is longer, the culture apparatus sampling trouble that existing laboratory is conventional.
Summary of the invention
The purpose of this utility model is just to provide the micro-algae reactor of a kind of new laboratory culture, it can effectively solve the conventional culture apparatus in existing laboratory well ventilation, poor fluidity, large, the sampling trouble of taking up room, be not suitable for the shortcoming that full exposure is cultivated.
The purpose of this utility model is achieved in that the micro-algae reactor of laboratory culture, that main body upper end is is cylindric, lower end is coniform, inside arrange front openings every light guide shell, be fixedly connected with main body by two side plates every light guide shell, main body upper end arranges top cover, on top cover, insert ventpipe and stopple coupon, and set out gas port.
The beneficial effects of the utility model are: 1. save space.Length be same cultivation amount air lift type photoresponse post 1/5, width is suitable with it; Width be same cultivation amount Erlenmeyer flask 1/4, length is suitable with it.2. sampling is convenient.By thief hole direct sampling, without device is taken apart.3. air-lift loop is effective.Combine by ventilation and guide shell, realize good liquid return.Compared with traditional air-lift loop device, its guide shell opening can adapt to the variation of nutrient solution liquid level.4. can realize full exposure and cultivate, improve culture efficiency.Traditional culture apparatus, in the time that cultivation is not suitable for micro-algae of full exposure cultivation, need to arrange the light dark period of incubator, and to prevent micro-algae to be subject to light excessively, growth is suppressed.And the utility model is by every the guide shell of light, coordinate air-lift loop, make micro-algae always in light and shade alternate environment fast, even if cultivating, full exposure can not make micro algae growth be suppressed yet.5. easy to use.This device is that laboratory study is used, convenient cleaning, dismounting.
Accompanying drawing explanation
Accompanying drawing 1 is the general effect figure of the main apparent place of the utility model, and accompanying drawing 2,3,4 is respectively the fractionation structure iron of top of the present utility model, inside and bottom.Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
Accompanying drawing 1 shows the overall structure of the main apparent place of the micro-algae reactor of the utility model laboratory culture, has top, bottom and inner three parts.
Accompanying drawing 4 shows the lower part of device, glass material.Its upper end 1 is cylindric, and screw thread is arranged at top, can screw combination with the upper part of device.Lower end 2 is coniform, and bottom is fired into sphere, and this part contributes to liquid return and under the drive of bubble, promotes liquid to rise.
Accompanying drawing 2 shows the upper part of device, the top cover 3 that support component is plastic material, and inside sidewalls has screw thread, corresponding with the screw thread shown in accompanying drawing 4.On top cover 3, there are three holes.Glass material airway 4 has been inserted in middle maximum hole.Shut with air-permeable envelope in the hole on the left side, for balance inner and outer air pressure.The sampling catheter 5 of glass material has been inserted in the hole on the right, and shut with the lid 6 of plastic material at ordinary times upper end, and when sampling, uncap is drawn sample with syringe.
Accompanying drawing 3 shows the member that is positioned at device inside.Member is mainly made up of fixed plate 8 and the guide shell 9 of glass material.Guide shell 9 one sides are opened rectangular opening, and to adapt to the variation of the nutrient solution page, and silver-plated in outside, this has guaranteed that inside is in the light, and reflects light to every the space in light guide shell 9 outsides, has increased light utilising efficiency, realizes the quick alternation of light and darkness in culturing process simultaneously.
By adding fresh algae liquid after the utility model sterilizing, be placed in constant temperature illumination box, constant temperature full exposure is cultivated.According to the particular requirement of cultivated frustule, by regulating gas flow rate in ventpipe 4 to control liquid velocity in draft tube in reactor.Can form good circulation in whole reactor, and coordinate reflective every light guide shell 9, manually manufactured the light dark period replacing fast, thereby the light retarding effect of releasing plant realize the full exposure condition cultivation of micro-algae.
Claims (1)
1. the micro-algae reactor of laboratory culture, it is characterized in that: there are three part detachable structures, that the upper end (1) of bottom is is cylindric, lower end (2) are coniform, inside arrange front openings every light guide shell (9), be fixedly connected with cylinder (1) by two side plates (8) every light guide shell (9), top arranges top cover (3), upper ventpipe (4) and the stopple coupon (5) of inserting of top cover (3), sets out gas port (7) on top cover (3).
