Problems solved by technology

However, this type of aerator needs to use a reel to complete the winding work during the strip winding process, and the participation of the reel will cause the lack of aeration area at this place, reducing the effective aeration area; in addition, the strip reel The wound aeration disc is easily pushed, deformed or even pushed apart under high air pressure, which seriously affects the aeration work

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as Figure 1 ~ Figure 3 As shown, the disc aerator includes a funnel-shaped installation cover 1, the bottom of the installation cover 1 is provided with an air inlet, and the air inlet is connected to the air inlet pipe 2, and the outer wall surface of the air inlet pipe 2 is With external thread. A hollow reel 3 is fixed at the center of the installation cover 1 , and an aeration disc placed inside the installation cover 1 is arranged on the reel 3 , and the aeration disc is formed by winding a strip 4 along the reel 3 . A sealing strip is provided between the strip 4 and the reel 3 to prevent air leakage and water leakage. A ring-shaped sealing strip is also arranged between the installation cover 1 and the aeration disc formed by winding the strip 4, and the sealing strip is fixed to the installation cover 1 by bolts...

Abstract

The invention relates to a disc aerator. The disc aerator includes an installation hood, the bottom of the installation hood is provided with an air inlet, a hollow reel is fixed at an internal center, and the reel is equipped with an aeration disc disposed in the installation hood; the aeration disc is formed by winding of an arc-shaped strip along the reel, the arc-shaped strip surface is equipped with arc-shaped aeration slots; the bottom of the aeration disc is equipped with a horizontal support rod, the support rod adopts the reel as the center, is in divergent arrangement, and is connected to the installation hood inner wall. The disc aerator also includes a connecting pipe that is disposed in the hollow inner part of the reel and is communicated with the air inlet, and a support frame that is connected to the connecting pipe and located at the reel top, the support frame is formed by enclosing of an arc-shaped top surface and a flat bottom surface, also the support frame is internally equipped with a gas distributing cavity communicated with the connecting pipe, and the outer surface of the support frame's arc-shaped top surface is coated with a microporous aeration diaphragm. The disc aerator obtained by the invention not only has large effective aeration service area, but also has good pressure bearing ability, and is easy for cleaning.

Description

technical field [0001] The invention relates to the technical field of sewage treatment devices, in particular to a disc aerator. Background technique [0002] The aerator is an essential equipment for aeration and oxygenation of water supply and drainage, and is one of the essential equipment for urban sewage treatment plants, and is directly related to the treatment efficiency and operation status of sewage treatment plants. Most of the urban sewage treatment plants in my country use the disc aerator in the underwater aerator to forcibly transfer the oxygen in the air to the liquid to obtain enough dissolved oxygen. The purpose of contacting organic matter with microorganisms and dissolved oxygen. Most of the blast aeration and oxygenation equipment used in sewage treatment plants are corundum aerators and diaphragm aerators. The aeration port of the corundum aerator is a fixed hole, which is easy to be blocked; while the opening of the aeration port of the diaphragm aera...
