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] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings:

[0018] like 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 three-way 6 and a second control valve 7 .

[0019] Eight of the culture tanks 4 can be used, and two adjacent culture tanks are set as a group, and an even number is used consecutively. like figure 1 Shown: set as (A1, A2, A3, A4 total of four groups), the several culture tanks 4 described in the present invention are made of transparent organic glass material.

[0020] The tops of the 8 culture tanks are respectively provided with screw caps 1, and the screw caps 1 are respectively provided with a drainage hole 8 and an air intake hole 9, the drainage hole 8 and the air intake hole 9 are respectively used for inserting the drainage pipe 3 and the air intake pipe 2; the intake pipe 2 is communicated with...

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 plurality of 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-lift circulating water algae cultivation system, which belongs to the technical field of algae cultivation devices. Background technique [0002] The mass culture of unicellular algae has always been an important research content that people are concerned about. The development of this research is of great significance for the development of aquaculture, innovation of water purification technology, and acquisition of high-value algal nutrients. In the development of aquaculture, shrimp, river crab, and shellfish need a lot of single-cell algae. Artificial breeding of aquatic animals such as shellfish can be successful only when a large number of protozoa-free, fresh and tender unicellular algae and shellfish are cultivated. In terms of water quality purification, the application of unicellular algae to purify sewage has attracted widespread interest. The research on sewage biological purification technology through the...
