Description

Technical Field

[0001] The utility model relates to an efficient sewage aeration device, belonging to the technical field of sewage treatment. Background Art

[0002] The aerobic biological treatment process is widely used in various industrial wastewater and urban domestic sewage treatment projects. Aeration is a key process link. Oxygen is filled into the sewage through an aeration device to provide oxygen for aerobic microorganisms to decompose organic matters and maintain the activity of aerobic microorganisms. In addition, aeration also plays a role in stirring and mixing to ensure the full contact of activated sludge, dissolved oxygen, and organic pollutants, and improve the sewage treatment effect.

[0003] At present, the mainstream aeration devices mainly consist of a blower, an oxygen delivery pipeline, and an oxygen diffusion device. The oxygen delivery pipeline is arranged at the bottom of the aeration tank, and the oxygen diffusion device is installed on the oxygen delivery pipeline.

[0004] The following problems generally exist in the actual application of the existing aeration devices:

[0005] The oxygen delivery pipeline and the oxygen diffusion device are fixed at the bottom of the aeration tank. The oxygen diffusion device is prone to falling off during operation, resulting in local air leakage, and ultimately may lead to the collapse of the aeration system. When replacing and maintaining, it is necessary to stop production and drain the water before operation, which is not convenient for maintenance. The aeration diaphragm of the oxygen diffusion device is made of rubber material, which is easy to age and has a short service life. After the diaphragm ages and tears, the aeration efficiency drops sharply, affecting the normal operation of the sewage treatment process.

[0006] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model

[0007] Aiming at the deficiencies in the background art, the utility model provides an efficient sewage aeration device, which can be conveniently installed and maintained subsequently.

[0011] Both ends of the porous pipe are respectively connected to the vertically arranged support pipe through the first flange joint, and the side part of the top of the support pipe is connected to the shunt pipe through the second flange joint; the shunt pipe has a cross-shaped structure, the top of the shunt pipe is connected to the air inlet pipe, and a lifting lug is fixedly installed on the air inlet pipe.

[0012] Further, the aeration plate is arranged vertically, and micropores are provided on the surface of the aeration plate.

[0013] Further, air inlet joints are respectively arranged at both ends of the aeration plate along the length direction, and the air inlet joints are arranged close to the top end of the aeration plate.

[0014] Further, there is a row of air holes arranged horizontally on the inner sides facing each other of the two porous pipes, and the air holes are used for inserting and fixing the air inlet joints at both ends of the aeration plate.

[0015] Further, the U-shaped bracket is located on both sides of the aeration plate along the length direction.

[0016] Further, both ends of the positioning plate are fixedly connected to the U-shaped bracket, and the positioning plate is located below the porous pipe.

[0017] Further, a plurality of uniformly distributed positioning grooves are arranged on the inner sides facing each other of the two positioning plates, and the positioning grooves are used for positioning the aeration plate.
