Description

Conjuncted tubulose aerator

Technical field

The utility model relates to the improvement of tubulose aerator structure.

Background technology

Aeration is an integral part in the sewage biochemical processing process, generally is used to promote bio-digestion to remove dissolved waste and suspension refuse.Aerating apparatus is called aerator, is fixed in artificial or natural bottom, aeration tank.Air or other gas in most cases are made of oxygen or contain oxygen, are transported to aerator in large quantities, and discharge a large amount of small bubbles by aerator.Because of buoyancy upwards floats, the oxygen dissolution in the bubble is in sewage in sewage for these bubbles.Oxygen is for aerobic bacteria existence, and bacterium consumes pollutent.

The structure that is used for the tubulose aerator of municipal wastewater and Industrial Wastewater Treatment can separated into two parts, and a part is to be used to support diaphragm pipe part, and another part is that the diaphragm pipe is connected to part on the gas distribution pipe.The tubulose aerator is the right and left that is connected to gas distribution pipe by two tubulose aerators symmetrically as the arrangement mode of whole aerating system.

At present, the tubulose aerator is to be a unit with a tubulose aerator mostly, and each tubulose aerator all has own independent web member.Web member mainly contains two kinds of forms, and a kind of is to be threaded, and installs threaded pipe, screw pipe cap on aeration tube and gas distribution pipe respectively in advance, and aeration tube relies on and is threadably fastened to above the gas distribution pipe.Another kind is the machine riveting mode, each aeration tube a semicircular base all arranged, the semicircle base butt joint back of two aeration tubes relies on bolt or fastener to be fastened on the gas distribution pipe, makes supporting tube be fixed in the both sides of gas distribution pipe; Gas enters in the sewage lagoon by gas distribution pipe, supporting tube and diaphragm, carries out the processing of sewage.But there is following shortcoming in this structure, and its member is comparatively complicated, and production efficiency is low, and during operation, is full of air in the tubulose aerator, thereby can produces buoyancy, and current also can produce thrust to the tubulose aerator simultaneously.More than two kinds of masterpieces be used on the existing tubulose aerator and the stress that produces can concentrate on aerator near gas distribution pipe " root ", be easy to cause fracture.

Summary of the invention

The utility model is exactly at the problems referred to above, provide a kind of simple in structure, production efficiency is high, the supporting tube conjuncted tubulose aerator of easy fracture not.

For reaching above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises the supporting tube of closed at both ends, supporting tube is provided with pore, supporting tube is outer, and setting has the diaphragm of micropore corresponding to pore, its structural feature supporting tube links to each other with gas distribution pipe by web member, described web member comprises mutual vertically disposed front band and lower catch hoop, penetratingly be provided with communicating pipe on front band and the lower catch hoop, front band is placed in the middle part of supporting tube, and lower catch hoop is placed on the gas distribution pipe; The both ends open of communicating pipe lays respectively in supporting tube and the gas distribution pipe.

The beneficial effects of the utility model: 1, simple in structure, the production efficiency height: primary member supporting tube of the present utility model is a solely pipe, supporting tube middle part connects by web member with gas distribution pipe, outside the two ends diaphragm is set after, supporting tube just forms two traditional tubulose aerators.Supporting tube can a formed by extrusion and tension, as long as just can manufacture two tubulose aerators at two baffle plates of supporting tube cavity internal fixing, production efficiency is improved.

2, supporting tube frangibility not: primary member supporting tube of the present utility model is a solely pipe, and when being connected with gas distribution pipe with the web member that designs in the utility model, stress distribution is even, thereby aeration tube easy fracture not.
