Screening device for grading algae subjected to algae suspension aeration continuous culture

Abstract

The invention discloses a screening device for grading algae subjected to algae suspension aeration continuous culture. The screening device comprises an algae continuous culture device and a screening device body, wherein the screening device body comprises a screening box body and at least one screening net plate, and the screening net plates are arranged in the screening box body and divide thescreening box body into a plurality of screening spaces; a liquid level device is arranged in the screening space located at the end of the screening box body; the screening space is connected with afirst liquid discharging pipe; the hole diameters of the screening net plates are sequentially reduced; a second liquid discharging pipe is arranged on the bottom wall of each screening space which is not connected with the first liquid discharging pipe; and a first electromagnetic valve, a second electromagnetic valve and the liquid level device are all electrically connected with a controller.According to the screening device, the first liquid discharge pipe, the first electromagnetic valve, the at least one screening net plate, the plurality of screening spaces, the second electromagneticvalve and the second liquid discharging pipe are arranged, so that the algae culture solution is discharged into the screening space connected with the first liquid discharging pipe through the firstliquid discharging pipe, and the algae culture solution is subjected to size grading while flowing under the action of liquid level difference.

Description

technical field [0001] The invention belongs to the technical field of algae cultivation, and in particular relates to a screening device for classifying algae bodies of algae suspension and aerated continuous culture. Background technique [0002] Cyanobacteria are prokaryotic organisms, also known as blue-green algae or cyanobacteria, usually in the form of particles. Cyanobacteria are widely distributed and spread all over the world. Environment plays a huge role. Among them, many blue-green algae (such as Anabaena) contain nitrogenase, which can directly carry out biological nitrogen fixation, which can be used to improve soil fertility and increase crop production; some blue-green algae can also be processed into food, such as Nostoc and common Nostoc fungus), spirulina, etc., and recently some scientists have discovered that through genetic engineering, cyanobacteria can be improved to produce butanediol, which is a former chemical used in the manufacture of fuels and...

Problems solved by technology

[0004] The object of the present invention is to provide a new screening device for grading algae bodies of algae suspended aerated continuous culture, aiming at the above-mentioned problems existing in the existing screening device for grading algae bodies of suspended aerated continuous culture, This kind of screening device for grading the algae bodies of algae suspended and aerated continuous culture is specially applied to the cultivation device. It solves the problem of algae body pollution caused by the contact between the algae body and the wall of the culture container during the suspension culture of the algae body, and can also The cultivated algae are graded and screened to ensure that the size of the algae is qualified, thereby reducing the production cost of the algae product and reducing the manual workload
