Alga taking system and method of spirulina culture machine

Abstract

The invention provides an alga taking system and an alga taking method of a spirulina culture machine. The alga taking system comprises a disinfection cabinet, an alga filtering cup, a box body, a cover body, a built-in light transmitting plate, an alga taking device, a diaphragm pump, a filter head, a liquid transportation pipe, an observation window and an alga taking reference column; the alga taking reference column is vertically arranged at the bottom of the box body; the diaphragm pump is located in a cavity composed of the cover body and the built-in plate; the alga taking device comprises a top cover, a liquid collection pipe and a cup type filter screen; the cup type filter screen comprises a cup body and a filter screen; the filter screen is stuck on an inner wall of the cup body; a second liquid inlet hole is formed in the upper side of the cup body and a cup edge is arranged at the top of the cup body; through holes are formed in the bottom and the outer side of the cup body; a first liquid inlet hole is formed in the upper side of the liquid collection pipe and a liquid outlet hole is formed in the bottom of the liquid collection pipe; the top cover is detachably connected with the liquid collection pipe; the cup type filter screen is arranged on the cover body; the filter head, the diaphragm pump and the first liquid inlet hole are connected in sequence through the liquid transportation pipe; and the first liquid inlet hole and the second liquid inlet hole are connected through contacting. The alga taking system provided by the invention has high sealing, cleaning and automation degrees and has the advantages that algae are convenient and rapid to take, are clean and can be take when people want to eat.

Description

Technical field [0001] The invention belongs to the technical field of microalgae research and cultivation equipment, and specifically relates to an algae extraction system and an algae extraction method of a spirulina cultivation machine. Background technique [0002] As a low-grade aquatic plant, spirulina is a natural weakly alkaline food with high nutritional value and good health and therapeutic value. In order to produce high-quality spirulina and achieve the purpose of daily fresh consumption, the development and application of spirulina culture machine as a biological household appliance has become a new hot spot in recent years. [0003] The form of Spirulina is tiny filaments, only 200-600um long, usually filtered through a 150-300 mesh filter, the green is muddy. However, the algae filaments are very fragile, improper operation will break it, affecting the quality and the amount of algae taken, and even the overflow of nutrients will bring about the growth of microorgan...

AI Technical Summary

Problems solved by technology

However, the algae filament is very fragile, improper operation will cause it to break, affect the quality, the amount of algae taken, and even the overflow of nutrients will bring about the growth of microorganisms and affect the continuous cultivation of spirulina

At present, the existing algae extraction equipment adopts the following methods to extract algae: 1. Manually extract algae directly from the algae liquid, which is primitive, rough, and cumbersome, and it is easy to cause contamination of the culture medium and decrease the purity of spirulina; 2. Set up a filter above the culture container. The algae solution is extracted through a submersible pump or a centrifugal pump, filtered through a filter bag, and the nutrient solution through the net is automatically returned to the culture container, so that the algae filaments are broken, and it is difficult to filter algae and continue to cultivate
