Problems solved by technology

At present, this kind of regular stirring or aeration process is mostly manual operation, which is not only time-consuming and laborious, but sometimes the stirring and aeration are not thorough, which fails to achieve the purpose of evenly distributing the upper and lower layers of the algae and effectively preventing the algae from settling and attaching to the wall

Embodiment Construction

[0017] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0018] Such as figure 1 As shown, it includes a screw cap 1, an air inlet pipe 2, a drain pipe 3, a culture tank 4, a first control valve 5, a tee 6 and a second control valve 7.

[0019] Described cultivating tank 4 can adopt 8, and adjacent two cultivating tanks are set as a group, are used in an even number. Such as figure 1 Shown: as (A1, A2, A3, A4 four groups), several culture tanks 4 described in the present invention are made of transparent plexiglass material.

[0020] Screw caps 1 are respectively installed on the tops of the 8 culture tanks, and drain holes 8 and air inlet holes 9 are respectively arranged on the screw caps 1, and the drain holes 8 and air inlet holes 9 are respectively used for inserting the drain pipe 3 and the air inlet pipe 2. The air inlet pipe 2 communicates with the drain pipe 3, one end of the drain pipe 3 is inse...

Abstract

The invention relates to an air-lift circulating-water algae culture system which comprises a plurality of culture tanks. Each two adjacent culture tanks are in a group. The top of each culture tank is provided with a screw cover which is provided with a drain hole and an air inlet. One end of a drain pipe is inserted into the first culture tank, and the other end of the drain pipe is inserted into another culture tank. A first control valve is disposed at the bottom of each of two adjacent culture tanks and is connected with a tee to form a U-shaped pipe set through a pipeline. The pluralityof U-shaped pipe sets are connected to form the whole algae culture system through pipelines. The air-lift circulating-water algae culture system allows the upper layer of algae and the lower layer of algae to distribute evenly, and accordingly algae sedimentation and adherence to walls are prevented effectively and the algae are promoted to grow fast and healthily. During aeration, the system guarantees cyclic flowing of water. Aeration and flowing are integrated, so that power input is reduced. The air-lift circulating-water algae culture system is scientific, feasible and efficient.

Description

technical field [0001] The invention relates to an air-lifting circulating water algae cultivation system, which belongs to the technical field of algae cultivation devices. Background technique [0002] The mass cultivation of unicellular algae has always been an important research content that people care about. The development of this research is of great significance for the development of aquaculture industry, innovation of water purification technology, and acquisition of high-value algae nutrients. In the development of aquaculture industry, a large number of unicellular algae are needed for the breeding of prawns, river crabs and shellfish. The quality of unicellular algae culture is related to the success or failure of the breeding, and it is the first condition for the success of aquatic animal breeding. Have only to cultivate a large amount of non-protozoan pollution, fresh and tender multiple unicellular algae, the artificial breeding of aquatic animals such as ...
