Environment-friendly alga culture device

Abstract

The invention belongs to the technical field of alga culture, and particularly relates to an environment-friendly alga culture device. For the problem that broken leaves and broken parts in algae often drift away along water flow to cause water source pollution easily, the following scheme is proposed now. The environment-friendly alga culture device comprises a culture box of a net-cylinder-shaped structure; a suspension rope is fixed in the middle of the bottom of the culture box; a balancing weight is fixed at the bottom end of the suspension rope; a shielding cylinder with openings in thetop and the bottom is arranged outside the culture box; and a plurality of fixed blocks are fixed at the top end of the position between the inner wall of the shielding cylinder and the outer wall ofthe culture box. According to the alga culture device, the algae are arranged in the culture box of the net cylinder structure; the water source pollution caused by the fact that the broken leaves andthe broken parts drift away along the water flow can be avoided through plugging operation of the solid shielding cylinder; and when the algae in the culture box are collected, the shielding cylindercan be directly lifted upwards, and the broken leaves can be conveniently collected and treated in a centralized mode through a limiting piece and limiting grooves.

Description

technical field [0001] The invention relates to the technical field of algae cultivation, in particular to an environment-friendly algae cultivation device. Background technique [0002] Algae is a kind of relatively primitive and ancient lower organisms. The structure of algae is simple, without the differentiation of roots, stems and leaves. Most of them are unicellular, colony or multicellular fronds. Algae belong to groups, and kelp is in the form of fronds. With the continuous development of cultivation technology, artificial cultivation of algae has gradually been derived, that is, the production process of algae reproduction and growth under artificial control. [0003] The process of artificial cultivation of algae plants mainly includes seedling cultivation and cultivation. In the process of cultivating large quantities of algae plants, multiple cultivation cages are often set up on the water source, so that the algae plants can be cultivated and grown inside the cu...

[0003] The process of artificial cultivation of algae plants mainly includes seedling cultivation and cultivation. In the process of cultivating large quantities of algae plants, multiple cultivation cages are often set up on the water source, so that the algae plants can be cultivated and grown inside the cultivation cages. Finally, the algae plants are collected by moving the net cages to the shore or salvaged as a whole. However, during the actual cultivation process, there are often broken leaves and broken parts in the algae plants, and the broken leaves and broken parts will float on the water surface. Floating along the water flow, it is easy to cause water pollution
