Abstract
The utility model discloses an alga culture apparatus with a fresnel lens. The alga culture apparatus comprises a bucket-shaped container with an opening and a top cover buckled on the opening of the bucket-shaped container, wherein a light source used or providing illumination needed by alga reproduction is arranged on the top cover; the fresnel lens is arranged on the emergent light path of the light source. According to the alga culture apparatus with the fresnel lens, a mode that the fresnel lens is arranged on the emergent light path of the light source, and the viewing angle of an emergent light beam is reduced is adopted, so that the proportion of the light beam projected on the inner wall of the bucket-shaped container is reduced, thus the attraction effect of alga, caused by the reflection of the light beam passing by the inner wall of the buckets-shaped container is reduced, and the wall attaching phenomenon is relieved.
Description
Technical field
The utility model relates to algae culture apparatus field, is specifically related to a kind of algatron with Fresnel Lenses.
Background technology
Spirulina is known abundant, the most balanced biology of nutritive ingredient of the mankind on the current earth.Hydrolysis of protein spirulina content is up to 65%-71%, and the amino acid of protein composition is similar to human blood protein, is very easily absorbed by the body.Spirulina is rich in the various bioactivators such as various VITAMIN, trace element, polysaccharides, algocyan, linolenic acid, para-insulin simultaneously, these effective constituents have under certain conditions and reduce cholesterol, separate kidney poison, improve the immunity function of human body, and promote that prostaglandin(PG) is synthetic, press down cancer anti-cancer, accelerate the multiple medicine and health care functions such as wound healing.
Spirulina Products on existing market mainly obtains by industrialized culture, industrialized culture mainly relies on natural condition as the open large-scale farming in: sunlight, ambient air temperature and in good time season, concentrate to gather and take that batch production equipment cleans, dewaters, be dried, compressing tablet or the filling industrialization finished product that become, finally come into the market to consume.Yet spirulina industrialized culture cost is high, and spirulina is after super-dry processing, and its nutritive ingredient suffers damage, and it does not often pass a test because of complete processing, and part composition is rotten, makes spirulina goods produce peculiar smell.
For the problems referred to above, a kind of cultural method of domestic spirulina has been proposed in prior art, the new living body that can realize spirulina by the method is edible, can effectively avoid the destruction to its precious nutritive ingredient in industrialization processing (dehydration, oven dry) process, improves healthy nutritive value.If the patent No. is 98124744.X, Chinese invention patent that name is called the method > > of a < < house cultivating edible fresh spirulina has described that family cultivates on a small scale and the method for edible spirulina.Yet in above-mentioned spirulina household cultural method, sticking to easily appears in spirulina in process of growth cultivates by the phenomenon on wall of container, i.e. adherent (knot wall) phenomenon.Adherent phenomenon will be unfavorable for the growth of spirulina, and affects attractive in appearance.
Existing family expenses spirulina cultivation machine comprises that bulk containers with opening, buckle closure are in the top cover of the opening of described bulk containers, described top cover comprises top cover under the upper top cover that connects by fixed sturcture and printing opacity, between described upper top cover and lower top cover, form top cover cavity, described top cover cavity is built-in with for the light source of the required illumination of algae reproduction is provided, and described light source is fixedly connected with upper top cover.
The nutrient solution liquid level of existing family expenses spirulina cultivation machine approaches the upper shed edge of bulk containers, the distance of the light source distance nutrient solution liquid level in top cover is also nearer, and general light source luminescent angle is all larger, if conventional fluorescent is that full angle is luminous, conventional LED light source lighting angle is generally 120 ° of left and right, the width of top cover is suitable with the width of bulk containers again, excessive lighting angle will project on the inwall of bulk containers too much light beam, and the algae such as spirulina have the light of becoming, habit warms up, therefore the spirulina cultivation machine of said structure easily makes algae be attached on bulk containers inwall, form adherent phenomenon.

Embodiment
Below in conjunction with accompanying drawing, the algatron of the utility model band Fresnel Lenses is described in further detail.
As depicted in figs. 1 and 2, a kind of algatron with Fresnel Lenses, comprises that the bulk containers 1, buckle closure of upper shed are in the top cover 2 of described bulk containers 1 upper opening.
Figure 2 shows that top cover 2 vertical section structural representations, be followed successively by from top to bottom upper top cover 21, light source 22, Fresnel Lenses 23 and lower top cover 24.Light source 22 adopts the LED light-emitting particles of SMD encapsulation, and light source 22 is bolted to connection with upper top cover 21, and upper top cover 21 and lower top cover 24 screw fixing by screw thread, between upper top cover 21 and lower top cover 24, form top cover cavity, and light source 22 is placed in top cover cavity.Fresnel Lenses 23 and lower top cover 24 directly adopt bonding mode to fix.
As shown in Figure 3, its outward appearance is disc to Fresnel Lenses 23 cross section structure schematic diagram, and diameter is 250mm, focal length is 90mm, the two sides of Fresnel Lenses 23 is respectively plane 231 and serrated face 232, when itself and lower top cover 24 are bonding, bonding by plane 231 and the lower top cover 24 of Fresnel Lenses 23.
Certainly, the all right another kind of form of top cover, the structure that adopts Fresnel Lenses 23 and lower top cover 24 to be integrated, top cover comprises that screw thread screws fixing upper top cover 21 and Fresnel Lenses 23, between upper top cover 21 and Fresnel Lenses 23, form top cover cavity, light source 22 is placed in top cover cavity.The cutting of Fresnel Lenses 23 is directly scribed on transparent lower top cover 24 surfaces, scribed the light-focusing function that a side surface of rear lower top cover 24 possesses with Fresnel Lenses 23, simplified system architecture.
The algatron of the utility model band Fresnel Lenses, during its work, first light source 22 outgoing beams converge by Fresnel Lenses 23, and its lighting angle reduces.Compare with additional Fresnel Lenses 23, more light beam directly projects in bulk containers 1, when algae culture, directly projects nutrient solution liquid level and is distributed in algae in nutrient solution and absorb and carry out photosynthesis and breed; Correspondingly, the light beam projecting on bulk containers inwall is few, has reduced light beam by the sucking action of tubbiness inwall 11 reflections to algae, thereby has alleviated adherent phenomenon.
Above-described embodiment has been described in detail the technical solution of the utility model and beneficial effect; be understood that and the foregoing is only most preferred embodiment of the present utility model; be not limited to the utility model; all any modifications of making within the scope of principle of the present utility model, supplement and be equal to replacement etc., within all should being included in protection domain of the present utility model.
