Plate bar type microporous aerator

Abstract

The invention discloses a plate bar type microporous aerator. The plate bar type microporous aerator comprises an arc-shaped plate bar, a resistance-free check valve, a rubber aeration membrane, a V-shaped pressing bar and an inserting plate type connection bottom plate. The top of the arc-shaped plate bar is an arc-shaped plate. Installing holes of the resistance-free check valve are formed in the arc-shaped plate in the length direction at a certain interval, and an air distribution channel is arranged below the arc-shaped plate. A chassis of the resistance-free check valve is located in the air distributing channel, and the arc-shaped plate is covered with a valve body of the resistance-free check valve. The arc-shaped plate and the valve body of the resistance-free check valve are covered with the rubber aeration membrane. Anti-disengaging bars on the two sides of the rubber aeration membrane are clamped in a V-shaped clamping grooves, with convex points, of the arc-shaped plate bar through the V-shaped pressing bar. The plate bar type microporous aerator can be used for a bottom air blowing aeration device and can also be used for a sewage treatment project of an oxidation ditch process, particularly the defects that the aeration efficiency of a surface aerating machine of the oxidation ditch process is poor, oxygen supply is not sufficient, and the mechanical fault rate is high are overcome, and the plate bar type microporous aerator is multipurpose.

Description

technical field [0001] The invention belongs to the field of aeration devices and relates to a slat type microporous aerator. Background technique [0002] Since the beginning of the 21st century, with the development of my country's industry and the improvement of people's living standards, environmental problems have increasingly affected people's lives, especially the cost of energy consumption for sewage treatment, purification and treatment is also rising . At the same time, our country has invested a lot of money and built a large number of urban and industrial sewage treatment plants. Due to the large population of our country and the large differences between regions, the process and equipment selection of the sewage treatment plants to be built are very different. The most typical one is A 2 O process and SBR process, the aeration equipment used includes surface aerator and bottom blowing microporous aerator equipment, etc. The existing aeration equipment has certa...
