Abstract
The utility model relates to the improvement of an elastic diaphragm type micropore aerator for water treatment, which is characterized in that an aeration diaphragm and a supporting seat are changed to have hollow annular arched curved surface structures to form an annular arched curved surface aerator. The utility model overcomes the defect that in the process of rising, bubble flows of an existing diaphragm aerator are easy to be influenced by water pressure to cause neck constriction and bubbling polymerization.
Description
Utility model be about to water treatment with the decline improvement of hole aerator of flexible sheet.
The flexible sheet micro-hole aerator is because its unique advantage, thereby is widely used in water treatment and makes the aeration element.Existing microporous diaphragm aerator adopts two dimensional structure usually, as disclosed diaphragm type plane disc aerators such as Chinese patents 90214660,92205599,96211722, its structure comprises the plane elasticity diaphragm that has micropore, and planar diaphragm support plate and bowl-type plenum chamber.The disk aeration membrane life-time service of this two dimensional structure can be because of aging tired lax, being directed at the diaphragm micropore can not be effectively all closed, and the rear film of can not guaranteeing to stop the supple of gas or steam is close to the supporting plate surface fully, thereby be easy to generate water body and pour in down a chimney, enter work plenum chamber and supply air line by the aeration membrane micropore, influence aeration efficient and safe operation.Increase reverse checkvalve, enter the distribution pipeline, increased operation and started and working resistance though can prevent to pour in down a chimney water; And can not stop water body to pour in down a chimney and enter aeration work distribution space.Secondly, two dimensional structure, after stopping aeration, mud easily precipitates and accumulates in the aerator surface in the water body, has increased resistance when operation starts once more.For overcoming its shortcoming, Chinese patent 98226099 discloses a kind of spherical flexible sheet micro-hole aerator, because aeration membrane and diaphragm support seat all adopt spherical cap-shaped structure, thereby guaranteed effectively that diaphragm can better be close to be pressed in the supporting base surface after stopping the supple of gas or steam, be situated between preferably determined water body pour in down a chimney and stop the supple of gas or steam after sludgd deposition.Yet above-mentioned aerator is in aeration process, the microbubble proportion that produces because of aeration is lighter, under the pressure effect of water (especially in) than deep water, microbubble stream easily causes radial compression (necking down) as Fig. 1 in uphill process, especially major diameter dish aerator, this necking down is just even more serious, such one is to be directed at bubble to disperse area and reduce, the 2nd, can cause microbubble in uphill process, to make bubbling polymerization become air pocket because of being compressed collision, can not effectively guarantee the omnidistance microbubble of bubble rising, these all will influence aeration efficient.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of not instrument can prevent effectively that water body from pouring in down a chimney and sludgd deposition, and can also effectively prevent radial compression and the bubbling polymerization that rising bubble flows, guarantee that the aeration bubble has the higher microporous diaphragm aerator of dispersing area.
The utility model purpose realizes, the main improvement is to make aeration membrane and supporting base into the ring-type arc-shaped curved surface that there is the perforation water channel at the middle part, form ring-type arc-shaped curved surface aerator, aerator generation cross section is the cyclic bubble flow like this, utilize aerator middle part to connect hollow water guide balance ring-type bubble flow inside and external pressure differential, reduce necking down that bubble flow causes because of hydraulic pressure and the bubbling polymerization that causes.Specifically, the utility model microporous diaphragm aerator comprises the elasticity aerator disk that has micropore, support the supporting base of aeration membrane and between aeration membrane and supporting base air supply channel, it is characterized in that said aeration membrane and supporting base are the ring-type arc-shaped curved surface.During aeration work, pressure air enters between cyclic aeration membrane and supporting base by air supply channel, under the supply gas pressure effect, the former aeration membrane integral body that is close on the ring-type slippery supporting seat is heaved left supporting base formation one work distribution space, thereby make pressure air by the evenly outside diffused aeration of the micropore on the aeration membrane; After stopping air feed, the distribution space of working between diaphragm and supporting base disappears, and aeration membrane is under hydraulic pressure and self elastic recovery acting in conjunction, and recovery is replied to be close to and is pressed together on annular surface supporting base surface.
The said ring-type arc-shaped curved surface of utility model structure, be meant that there is the water stream channel of perforation at the aerator middle part with arc-shaped curved surface, it can be the hollow water stream channel that in the middle of aerator, has circle or other shapes, also can be to have some through holes at arc-shaped curved surface aerator middle part, as be through hole or the cluster through hole that circle is arranged, the aerator shape also can be non-circular shape structure, and these all do not have especially places restrictions on, and is that the cyclic bubble flow all can as long as aerator can produce the cross section.There is the current post bubble flow central zone, and just energy balance bubble flow center and external pressure do not make bubble flow that tangible compression is radially arranged under the hydraulic pressure effect.For improving the work-ing life of aeration membrane, make aeration membrane that less resistance is arranged again simultaneously, utility model can radially be provided with some thickening muscle on thin aeration membrane.For reducing aeration resistance, reach and effectively discharge dirt particle in the air feed, micropore should adopt rhizoma sparganic or many ribs structure on the utility model aeration membrane, and the micropore of this structure has easy expansion opening, and aeration resistance is little, and particulate is also run out of easily in the air feed.
Description below in conjunction with an indefiniteness embodiment further specifies utility model, but that utility model structure is not limited to embodiment is described.
Fig. 1 is not for there being the water stream channel of perforation aeration view.
Fig. 2 is a utility model aeration view.
Fig. 3 is an embodiment aerator structural representation.
Fig. 4 is a supporting base plan structure synoptic diagram.
Fig. 5 is rhizoma sparganic and four prismatic micropore enlarged diagrams.
Embodiment: referring to Fig. 3～5, aerator is by circular arc-shaped surface supporting base 3 and be close to the circular circular arc rubber diaphragm 1 that the supporting base surface has prism micropore 2, reach the spill air supply channel 4 that radially is located on the supporting base and form, there is good hermetic seal on diaphragm inner and outer ring limit and supporting base inner and outer ring limit.Cross is provided with four thickening muscle 5 on the aeration membrane.
The utility model aerator is not one to be decided to be annular and arc-shaped surface structure; other hollow curved surfaces and middle part have some through holes; and the aerator that constitutes such as the air supply duct of tubular perforate, can reach the utility model purpose too, belong to the utility model protection scope.
The utility model aerator, owing to adopt the aeration membrane and the supporting base of hollow and annular arc-shaped curved surface, make aerator can produce the ring-type bubble flow, effectively like this utilize the hollow water flowing in aerator middle part to come balance ring-type bubble flow inside and external pressure differential, reduce bubble flow because of radially necking down and bubbling polymerization that hydraulic pressure causes, what increased the aeration bubble disperses function and service area.Rhizoma sparganic or many ribs micropore, and the thickening muscle that radially is provided with on the diaphragm had both reduced aeration resistance, had prolonged the work-ing life of aeration membrane again.The utility model aerator, even aeration membrane is tired lax because of use causes, because arc-shaped curved surface structure diaphragm also can be close to Bao Meng on the supporting base surface, block-water performance improves greatly to make aerator stop the supple of gas or steam afterwards.Arc curve also makes aerator after quitting work, surface mud more easily fell when the surface was difficult for accumulated sludge and aeration work, and it is big to have an aeration service area, can reduce the aerator configuration and cause the dead angle, force-bearing situation is good during arc-shaped curved surface diaphragm aeration work simultaneously, and this is favourable to prolonging diaphragm work-ing life.
