Abstract

The invention relates to a disc diaphragm aerator. The disc diaphragm aerator comprises a spiral gland, a diaphragm and a base, wherein the diaphragm is arranged between the spiral gland and the base, a flow guide support plate is arranged between the diaphragm and the base, a check valve integrating a hole and a valve is arranged between the flow guide support plate and the base, a filter cover is arranged on the base, an inverted-saddle-shaped wedge plate is arranged below the base, multiple through holes are formed in the diaphragm, and through holes are formed in the edges of the periphery of the flow guide support plate; the base is composed of a bottom disc and a saddle-shaped support, holes are formed in the bottom disc and the saddle-shaped support respectively, the bottom disc is fixedly connected to the saddle-shaped support through a hollow bolt, an internal thread is arranged in the bottom disc and is matched with an external thread outside the spiral gland, and an external thread is arranged outside the bottom disc; an internal thread arranged on the inner wall of an opening in the lower end of the filter cover is matched with an external thread outside the bottom disc, and the filter cover is connected to the bottom disc through threads. The disc diaphragm aerator is not prone to blockage, large in effective aeration area, high in strength, long in service life and high in seal performance and effectively prevents backflow of a water body.

Description

technical field [0001] The invention relates to an aerator, in particular to a disc type membrane aerator. Background technique [0002] The aerator is an essential equipment for aeration and oxygenation of water supply and drainage. According to the method of use, it can be divided into surface aerators and underwater aerators. The underwater aerators mainly include microporous aerators and jet aerators. Among them, the disc diaphragm aerator is one of the microporous aerators. The disc diaphragm aerator is the latest aeration device developed in the 1980s. The diameter of the aeration bubbles of this device is small, and the diameter of the gas-liquid interface Small size, large gas-liquid interface area, uniform bubble diffusion, no hole clogging, strong corrosion resistance, 40% lower energy consumption than conventional product fixed spiral aerators, diffuse flow aerators and perforated tube aerators, or Increase sewage treatment capacity by 40%. It is especially suit...
