Technical field
The invention belongs to microdisk electrode engineer equipment and technical field, is related to a kind of microalgae training for rotating and being reflected with light
Support device.
Background technology
As the term suggests microalgae generally refers to unicellular alga, that is, the plant of only one cell i.e. small algae,
Its species is various, vdiverse in function, is the basis of aquatic ecosystem productivity, and tool has been widely used.Microalgae in waters,
It is exactly phytoplankton, its ecological functions is equal to the green plants of land, carries out photosynthesis, is its in aquatic ecosystem
His trophic level biology provides most of matter and energy source, is the important feed source of fish production.Particularly, no
Congener microalgae has different characteristics, and can specifically synthesize has important medical value, health value, warp with accumulating some
The material for value of helping, such as carotenoid, the microalgae of astaxanthin are produced, and oil-rich microalgae, the microalgae of enrichment protein, spiral shell
Algae etc. is revolved, is a very big industry for the foregoing culture with important use and economic value microalgae.
In view of the important value and purposes of microalgae, the patented technology about microdisk electrode is numerous, there is as many as thousands of items.
As a kind of single celled plant, the culture of microalgae needs to provide suitable illumination, nutritive salt, aquatic environment condition, quite a lot of
Patented technology proposed around these problems and demand.For example, to improve the light utilization ratio of microdisk electrode, application number
Proposed for 2011203597923,2014103094299,2014205459372 Patents and light harvesting is rotated built in exterior lighting
The different illumination thinking such as cover or internal illumination and rotation light；To optimize mixed effect, avoiding microalgae deposition from growing nonparasitically upon another plant
The patent such as defect, Application No. 2012207005568,201420668458X, 2015102003583 proposes different rotary side
The microdisk electrode mode of formula.Based on microalgae unique ecological functions and feature, in possible future, microdisk electrode is very potential should
Necessity and important component of the ecosystem, but mesh are artificially built in the outer space in space development, aerospace journey, turning into
Before, there is not yet the outer space is agravic or microgravity environment in, carry out the thinking and Patent design of microdisk electrode.
The content of the invention
Present invention seek to address that above-mentioned have problem in the prior art, it is proposed that a kind of to rotate and with the microalgae of light reflection
Culture apparatus, it is adapted to the culture of various microalgaes, is particularly suitable for applied in the outer space environment under agravic or microgravity condition
Carry out the culture of microalgae.
The technical scheme is that：
It is a kind of rotate and with light reflection micro algae culturing device, the device include support base, rotating basis, shell body,
Light source and charging stirring jet pipe；Rotating basis is positioned at support pedestal top, and the outer ring of rotating basis is rotating part, and it rotates speed
Degree and direction of rotation are regulated and controled by control element；Shell body is opaque spherical shell, is fixed on the rotatable portion of rotating basis
Divide top, together rotated with rotating basis, its structural strength is enough to ensure that rotating part highest after micro algae culturing liquid is filled it up with turns
Safety under fast rotation status, and retain 20% safe clearance.Shell body inwall liner specular reflective material, minute surface is inside,
Effect is the light sent in ball interior reflection sphere center position light source；Ventilative and peep hole, the hole are set at the top of shell body
Place's covering breathable films are only capable of can not be by liquid by gas, the observation for internal microdisk electrode situation；In shell body
Heart position sets light source, and light source is fixed on the center non-rotating part of rotating basis, and accesses supply of electric power, light source by pedestal
Outside is kept apart itself and the micro algae culturing liquid in device by transparent Bright Source Protection cover；On the rotating part of rotating basis
The even more than two charging stirring jet pipes of arrangement.
Further, the intensity of light source, wavelength are regulated and controled by control element, it is ensured that the light that light source is sent can arrive at mirror
Face reflective wall.The diameter of integral spherical culture apparatus should not be too big, and increases the diameter of centre of sphere Bright Source Protection cover, ensures microalgae
When culture latter stage microalgae density is higher, the light of light source can also arrive at housing and be reflected, that is to say, that light source to liner
The distance of minute surface not should be greater than the numerical value of transparency during microalgae concentration highest.
Further, the rotating speed of the outer ring rotating part of described rotating basis, can keep micro algae culturing liquid in spheroid
Under agravic or microgravity condition, aggregation is close on bilayer sphere shell, without loss everywhere.
Further, the charging stirring jet pipe on the rotating part, its material spray speed and direction are adjusted by control element
Control, the addition of nutritive salt, nutrient solution can be carried out by this pipe, cultured microalgae liquid can also be carried out and collected.The charge pipe
The angle of charging, the flow velocity of charging can adjust, and can be rotated with the rotation of culture spheroid, addition available for feed liquid,
Collect, can be used for the inner loop of feed liquid, with reference to the rotational case of rotating part, the stabilization in maintenance micro algae culturing liquid flow field
With it is uniform, do not formed microalgae deposition and flocculation aggregation.
Beneficial effects of the present invention are, there is provided rotation and with the micro algae culturing device of light reflection, be suitable for various micro-
The culture of algae, its rotating basis drive spherical shell to rotate, and then the rotation for the viscosity drive whole beer for passing through liquid, its
The inertia that is formed of centrifugal force is rotated, all nutrient solutions can be gathered in using minute surface inner casing as on the spheroid at bottom, to a certain extent
The effect of " simulated gravity " can be served as, so as under the agravic or microgravity condition suitable for the outer space, aerospace way
Microdisk electrode work.The charge pipe of bottom base, in addition to addition nutrient solution and nutritive salt, it can also carry out the circulation of nutrient solution
Injection and agitation, with reference to the rotation of spheroid and pedestal, maintain the outer space agravic or microgravity condition under microdisk electrode flow field
The stability of environment, avoid flocculation and the deposition of microalgae.Another feature of the present invention is that spheroid liner mirror-reflection housing can
The light launched with reflection source in all directions, and unlimited multiple roundtrip can be carried out in ball interior, until
Light particle is utilized and absorbed by microalgae progress photosynthesis.That is, the spherical liner mirror-reflection microalgae training of the present invention
Device is supported, equivalent to the black matrix of a light, in addition to the observation air-vent of upper end fritter, light source is launched at the internal centre of sphere
Light can all be absorbed by microdisk electrode photosynthesis, and without the excessive of light, therefore, optical energy utilization efficiency is able to pole
Big raising.
