Semi-open type water bearing plug-flow aerator

Abstract

The invention relates to a semi-open type water bearing plug-flow aerator. A semi-open type water bearing is arranged at the lower part of a hollow driving shaft by a water bearing sleeve core in a sleeving manner and comprises a left body and a right body which have semi-open symmetrical structures; the left body comprises a left-side plane flange, two side longitudinal flanges, a middle tubularbody, a bearing working surface coating layer and fall preventing barb bodies; one end surface of the middle tubular body is connected with the left-side plane flange; an upper open side and a lower open side of a semicircular tubular structure are both connected with the two side longitudinal flanges; a plurality of fall preventing barb bodies which are integrally arranged in a line manner in thecircumferential direction and the longitudinal direction of a bore are welded to the surface of the bore of the middle tubular body; the bearing working surface coating layer uniformly covers the surface of an inner hole of the middle tubular body to serve as a bearing working surface; the fall preventing barb bodies are naturally submerged and embedded in the bearing working surface coating layer. The semi-open type water bearing plug-flow aerator adopts a semi-open type water bearing composite material structural form, is stable and reliable in transmission support and is convenient and quick in mounting and maintenance.

Description

technical field [0001] The invention relates to a sewage treatment aeration device, in particular to a semi-open water bearing push-flow aerator. technical background [0002] Aeration is the core of sewage treatment. Aeration equipment is the mechanical equipment that adds air to sewage. Surface aeration and bottom aeration equipment are generally used when new sewage treatment plants are newly built. However, some sewage treatment plants meet lower discharge standards when they are built. In the later period, the standard will be upgraded to increase the amount of aeration and oxygenation. The most hope is to directly increase the equipment without changing any inherent settings to meet the requirements of the standard increase. However, some equipment that increases the aeration amount on the market currently has a loose structure. , Unscientific transmission structure, unreasonable transmission parts in water, inconvenient assembly and disassembly, etc. lead to high fail...

[0002] Aeration is the core of sewage treatment. Aeration equipment is the mechanical equipment that adds air to sewage. Surface aeration and bottom aeration equipment are generally used when new sewage treatment plants are newly built. However, some sewage treatment plants meet lower discharge standards when they are built. In the later period, the standard will be upgraded to increase the amount of aeration and oxygenation. The most hope is to directly increase the equipment, without changing any inherent settings to meet the requirements of the standard increase. However, some equipment that increases the aeration amount on the market currently has a loose structure. , Unscientific transmission structure, unreasonable transmission parts in water, inconvenient assembly and disassembly, etc. lead to high failure rate and low efficiency, which cannot meet the requirements expected by users
