Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, relates to a kind of aerating apparatus, particularly a kind of micro-hole aerator.
Background technology
In numerous methods of WWT; It is a kind of economical and effective method that aerobe is handled; The factor that influences the aerobe treatment effect is a lot, and one of wherein important factor is in the sewage sufficient dissolved oxygen to be arranged, and aerator is the key device of oxygen supply in sewage.All use rubber diaphragm disc type micro-hole aerator in the WWT at present; This type micro-hole aerator is all having performance preferably aspect aeration effect, coefficient of oxygen utilization and the dynamicefficiency, but this micro-hole aerator is prone to push away long-pending mud after operation after a while on the rubber diaphragm; Blocking microporous; Reduce aeration efficient,, can cause the rubber diaphragm part when the expansion strained condition, to be prone to form stress concentration so in addition because the chassis of micro-hole aerator and rubber diaphragm are the plane cooperation; Rubber diaphragm is prone to produce fatigue and tears in expansion process repeatedly, has reduced the work-ing life of micro-hole aerator.
To the problem that exists, people have made various designs and improvement to micro-hole aerator, and some has also applied for patent, and for example the Chinese patent documents and materials disclose a kind of rubber diaphragm micro-hole aerator [application number: 200720040706.6; Granted publication number: CN201071321Y], it comprises spherical arc shape pedestal and the Bao Meng mipor rubber aeration membrane on pedestal, spherical arc shape base support membrane surface has some roads radial groove and at least one annular groove that is communicated with the top air vent.
Above-mentioned rubber diaphragm micro-hole aerator in use, the top air feed through radially with circumferential groove many places air feed, make aeration membrane expansion leave the base-plates surface aeration easily; Aeration efficient is high, but the periphery of its rubber diaphragm is directly to be pressed on the pedestal through pressure ring, in the use when rubber diaphragm expands; The perimeter of rubber diaphragm is stressed bigger; Periphery through rubber diaphragm after a while breaks away from pressure ring easily, directly causes aeration to lose efficacy, and work-ing life is short.
Summary of the invention
The purpose of the utility model is to the problems referred to above that exist in the prior art, provides that a kind of structural orientation stability is good, the micro-hole aerator of long service life.
The purpose of the utility model can realize through following technical proposal: a kind of micro-hole aerator; Comprise rubber diaphragm and discoid pedestal; Described rubber diaphragm is coated on the micropore that pedestal upper surface and rubber diaphragm have a plurality of perforations; Described pedestal lower surface is provided with the locating structure that supplies the pedestal installing and locating to use, and described pedestal middle part has the through hole of UNICOM's pedestal upper surface and lower surface, it is characterized in that; Described rubber diaphragm edge and susceptor edge are along being halved together the pressure ring that is connected the rubber diaphragm edge is compressed on the described pedestal.
This micro-hole aerator is fixed on the aeration tube through locating structure, and aeration tube is a prior art, is not giving unnecessary details at this.During the work of this micro-hole aerator, aeration tube is air feed in through hole, and air-flow gets between pedestal upper surface and the rubber diaphragm, and the rubber diaphragm protuberance expands, and micropore opens on it, and gas evenly is diffused in the sewage through micropore; After aeration tube stopped air feed, the rubber diaphragm retraction was closely attached on pedestal upper surface, and the micropore on the rubber diaphragm is closed.Because rubber diaphragm edge and pedestal upper surface edge are halved together, therefore the rubber diaphragm edge can not break away from pedestal when expansion deformation, and rubber diaphragm and pedestal firm position property are good, long service life.
