Microporous aeration disc convenient for long-term efficient use

Abstract

The invention relates to the field of water body oxygenation equipment, and discloses a microporous aeration disc convenient for long-term efficient use. The microporous aeration disc comprises a fixed air inlet pipe, wherein the top of the fixed air inlet pipe is fixedly sleeved with a lower partition plate, the outer edge of the top of the lower partition plate is fixedly connected with an annular air film, the annular air film penetrates through tiny aeration holes in the side direction, and the top end of the annular air film is fixedly connected with an upper partition plate. According tothe microporous aeration disc, a cavity is formed by the lower partition plate, the annular air film and the upper partition plate; post ventilation, the upper partition plate moves upwards to integrally stretch the annular air film; the stretching surface of the annular air film is uniformly stressed; the diameters of the aeration holes in all the positions in the stretching state are similar, so that generated tiny bubbles are uniform, the aeration efficiency is improved, meanwhile, airflow is sprayed out from the side face of the annular air film; after the multiple sets of aeration discsare arranged to work at the same time, bubbles have a good mutual stirring effect, and the aeration quality is further improved.

Description

technical field [0001] The invention relates to the field of water body oxygenation equipment, in particular to a microporous aeration disc which is convenient for long-term and efficient use. Background technique [0002] The aeration plate is an important part of the aeration equipment. The air in the go board is dispersed into micro-bubbles through the aeration plate, so that the air in the chessboard can be quickly melted into the water, thereby oxygenating the water. It is commonly used in sewage treatment and aquaculture field. [0003] The principle of using the existing aeration pan is as follows (refer to Figure 5 ): The air transported by the fan enters the tray 10 through the fixed air intake pipe, so that the air film expands and protrudes, and the micropores on the air film expand by themselves to ensure that the air passes through, and when the aeration is stopped, the air film shrinks and the micropores is closed. [0004] However, during the use of the exi...
