Bidirection counter current type micro algae culturing device

Abstract

The present invention belongs to the field of microalgae culture technology, in the concrete, it relates to a closed type bidirectional counter-current microalgae culture equipment for culturing hydrobiological bait in aquaculture production. Said equipment includes the following several portions: plastic film culture bag, internal light source, external light source, air filter and flow-guiding barrel. Besides, said invention also provides its working principle and concrete operation method.

Description

Technical field

[0001] The invention relates to microalgae cultivation technology, in particular to a two-way countercurrent microalgae cultivation device for closed cultivation of main aquatic organism bait used in aquaculture production. Background technique

[0002] The biological bait after manual screening and artificial cultivation is a kind of high-quality bait for aquatic animal breeding, especially seed production, and plays an irreplaceable role in production. Illumination, salinity, temperature, pH, etc. are the main environmental factors that affect the growth of algae. At present, open cultivation in cement pools is mainly used in production. This method has relatively simple equipment, but the contact area between the algae liquid and the air is large, and it is easy to be affected by harmful organisms. Pollution, and is greatly affected by human, season, weather and other factors, resulting in low production capacity, poor stability, weak anti-risk ability, an...

Embodiment Construction

[0022] like figure 1 As shown, the two-way counter-current microalgae culture device of the present invention is composed of plastic film culture bag 1, built-in light source 6, external light source 4, air filter device, diversion barrel 3 and other main parts, and culture bag 1 is provided with diversion barrel 3, Its outside is provided with external light source, and the air filtered by the air filter device reaches the bottom of the diversion barrel 3 through the inflatable tube 2 and the air stone 14. The side walls of the diversion barrel 3 are provided with diversion holes 7 up and down. The glass tube 5 has a built-in light source placed in the plexiglass tube 5 . The plastic film culture bag 1 is cylindrical, with a diameter of 0.3-0.7 meters and a height of 1.0-2.0 meters. The material is polyethylene PE, and the wall thickness is 0.06-0.12 mm. The bottom of the plastic film culture bag 1 is provided with a base 8, and the plastic film culture bag 1 is placed in a ...
