Description

Technical Field

[0001] The utility model relates to the technical field of microporous aerators, in particular to an anti-blocking type microporous aerator. Background Art

[0002] Microporous aerator, as an efficient oxygen transfer device, is widely used in industrial fields such as sewage treatment and biological reaction. Its unique structure and functional design enable it to efficiently transport oxygen into the liquid and provide sufficient oxygen support for biological reaction.

[0003] The core component of the microporous aerator is a dense layer of microporous membrane. These micropores are small in diameter and evenly distributed, which can effectively prevent liquid backflow while ensuring smooth oxygen transfer.

[0004] The prior art publication number is CN218262179U, which is an anti-blocking microporous aerator, comprising an air cavity cover, a fixing ring is movably connected to the lower part of the air cavity cover, an aeration plate is threadedly connected to the outer wall of the air cavity cover, and an air guide sleeve is fixedly connected to the surface of the aeration plate.

[0005] Although the microporous aerator has a certain anti-blocking function, in actual use, since its air guide holes are arranged on the side wall of the air guide sleeve, during the aeration process, the microbubbles generated after the gas is exposed will mix and collide, and then aggregate into large bubbles, reducing the effective contact area between gas and water, thereby affecting the oxygenation transfer efficiency of the aerator. For this reason, improvements are proposed. Utility Model Content
