Embodiment 1

[0014] Embodiment 1: High-efficiency divergent microporous aerator, including a support tube 1, a membrane 2 set on the surface of the support tube 1, the support tube 1 is evenly distributed with aeration holes 1.1, and the support tube 1 is coated on the upper surface The thickness of the diaphragm 2 is greater than that of the diaphragm 2 covering the lower surface of the support tube 1 . The thickness of the diaphragm 2 on the upper surface of the support tube 1 is three times the thickness of the diaphragm 2 on the lower surface of the support tube 1 . The aeration hole 1.1 is a tapered hole with a large bottom and a small top, and a spiral notch 1.1.1 is processed in the tapered hole. The ratio of tapered hole to hole size is 2.8:1. Both ends of the diaphragm 2 are sealed and fixed with the support tube 1 by the hoop 3 .

Abstract

The invention discloses a high-efficiency divergent type microporous aerator. The high-efficiency divergent type microporous aerator comprises a supporting pipe and a diaphragm sleeving the surface of the supporting pipe, wherein aerating holes are uniformly distributed on the supporting pipe; and the thickness of the diaphragm coated on the upper surface of the supporting pipe is larger than that of the diaphragm coated on the lower surface of the supporting pipe. The high-efficiency divergent type microporous aerator disclosed by the invention has the advantages that the thickness of the diaphragm is gradually changed, the resistance is uniform, the ventilation volume is large, the service life is long, the aeration area is large and the bottom of a pond is not easy to deposit mud.

Description

technical field [0001] The invention relates to a high-efficiency divergent aerator for water treatment and oxygenation, in particular to a microporous aerator with a thick upper layer and a thinner lower layer of an aeration membrane, uniform aeration, long service life, and high utilization rate of the aeration area. Background technique [0002] Diaphragm aerator is used in water treatment to supply the required air (oxygen) as a kind of oxygenation equipment. Because of its advantages of small diffusion bubbles, large air-water contact surface and high oxygen exchange rate, it is widely used at present. The basic structure is the air pipe, the support pipe connected to the air pipe, etc., and the diaphragm wrapped on the support pipe is generally made of EPDM rubber, silicone rubber, plastic and other mixed materials. Air (or oxygen 〉It is sprayed out from the micropores of the dia...
