Description

The diaphragm aerator

Technical field

The utility model relates to a kind of aeration aerating device that is used for town sewage improvement and Industrial Wastewater Treatment, is used for the diaphragm aerator of aeration aerating in the bio-aeration pool that especially utilizes biochemical technology to dispose of sewage.

Background technology

At present, town sewage administer and Industrial Wastewater Treatment in, more as the form of the aerator of aeration aerating device, the aerator of general use is made up of hollow centibar, adjustment dish, pallet and diaphragm etc.Aerator is installed in the perforate of air line, and air enters into plenum chamber from the centibar inside of aerator, discharges the circumferential gap between adjustment dish and pallet through all being press-fitted behind the gas.The top of adjustment dish is provided with the rubber lid, when stopping the supple of gas or steam, rely on the elastic contribution of rubber lid rubber that circumferential gap is sealed rapidly, thereby the assurance slit is not blocked by mud.The deficiency of this structure is that the active area of rubber lid is bigger, thereby must need to increase reactive force on its plane of action in order to reach partially sealed preferably effect, thereby causes single load to cause fatigue damage greatly and easily; Use under the condition of bigger single load, the working life of its rubber is generally not long, thereby causes the anti-blocking function of aerator to lose efficacy because of the aging distortion of rubber, has reduced the work reliability and the life-span of aerator, has increased maintenance cost.In addition, above-mentioned aerator also exists complex structure, component are many, process and assemble is difficult deficiency.

The utility model content

Lost efficacy easily and baroque deficiency in order to overcome existing aerator anti-blocking function, technical problem to be solved in the utility model provides a kind ofly utilizes perforate on the diaphragm to carry out aeration and anti-blocking, single load diaphragm aerator little, simple in structure.

The technical scheme that its technical problem that solves the utility model adopts is: the diaphragm aerator, be included in the perforate on the air line, the diaphragm that has eyelet, loam cake and lower cover, described perforate is arranged on below the horizontal center line of air line, diaphragm arrangement is between air line and lower cover, loam cake and lower cover compress diaphragm and cover in the perforate of air line by locking latches, and lower cover is provided with and the corresponding aeration opening of eyelet on the diaphragm.Air is directly discharged and to be carried out aeration by covering diaphragm-operated eyelet in the perforate from air line, when stopping air feed, the diaphragm-operated eyelet under the effect of screen resilience with the eyelet closure.

The beneficial effects of the utility model are, owing to adopted the diaphragm that will have eyelet to compress and cover mode in the perforate of air line, make air directly by covering diaphragm-operated eyelet discharge the carrying out aeration in the perforate, when stopping air feed, the diaphragm-operated eyelet is closed voluntarily with eyelet under the effect of screen resilience, thereby guarantees that eyelet is not blocked by mud.Because above-mentioned perforate is arranged on below the horizontal center line of air line, thereby its diaphragm is not subjected to the influence of stackings such as filtrate.Because the stressed active area of this diaphragm-operated is less, thereby single load is little, diaphragm is difficult for aging distortion.This aerator bubble diameter is little, the contacted area of gas-liquid is big, gas distribution evenly, oxygen absorption rate and dynamic efficiency height, low, the installation, easy to use of energy consumption, also have the diaphragm long service life, water body does not pour in down a chimney, do not produce advantages such as the diaphragm eyelet stops up, operating performance is stable, convenient disassembly.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1～shown in Figure 4, the diaphragm aerator is included in the perforate 2 on the air line 1, the diaphragm 4 that has eyelet 3, loam cake 5 and

lower cover

6, and 6 pairs of loam cake 5 and lower covers are clipped on the air line 1, and its external diameter to the barrel bore that presss from both sides the back and form and air line 1 is suitable.Air line 1 can adopt ABS plastic pipe, steel pipe etc., and barrier film 4 can adopt high performance synthetic rubber to make, and loam cake 5 and lower cover 6 all can adopt ABS plastic to make.Described perforate 2 is arranged on below the horizontal center line of air line 1, diaphragm 4 is arranged between air line 1 and the lower cover 6, loam cake 5 and lower cover 6 compress diaphragm 4 and cover in the perforate 2 of air line 1 by locking latches 7, and lower cover 6 is provided with and the corresponding aeration opening 8 of eyelet 3 on the diaphragm 4.Eyelet 3 on the diaphragm 4 can be one, also can be a plurality of, and what of eyelet 3 are determined according to the long-pending size of membrane surface.The bottom best results that is arranged on air line 1 is especially adopted in perforate 2, and the gas-liquid of the air bubble that the eyelet 3 that its objective is can increase from the diaphragm 4 the is discharged area that contacts can also avoid the direct heap of filtrate etc. to press simultaneously.

Above-mentioned diaphragm 4 is provided with the seamed edge 9 of projection, this seamed edge 9 is continuous or the protruding seamed edge around eyelet 3 distributions of interruption, its objective is and make that by lower cover 6 with diaphragm 4 pressings and when covering in the perforate 2 of air line 1, more tight, the peripheral sealing effectiveness of its covering is better.Same reason, also can be provided with boss 10 on the described lower cover 6, described boss 10 is arranged on the inboard and corresponding with the position of above-mentioned seamed edge 9 of above-mentioned seamed edge 9 and cooperatively interacts, like this, not only can be with in the tight perforate 2 that covers air line 1 of diaphragm 4, simultaneously can also make diaphragm 4 on lower cover 6, locate, prevent the displacement and the play of diaphragm 4.The perforate that makes air line 12 for convenience aligns with the eyelet 3 on the diaphragm 4, and guarantee displacement not to take place in the process of using and misplace, the horizontal center line of air line 1 to be being provided with pilot hole 11, and loam cake 5 is provided with the steady brace 12 corresponding and suitable with pilot hole 11.Described pilot hole 11 is preferably disposed on the top of air line 1, can be through hole, also can be blind hole or pit.Steady brace 12 is a cone surface with the contact surface of pilot hole 11, seals in order to location preferably with to the pilot hole of through hole.Locking latches 7 can adopt the bolt pair to carry out fixing and locking, also can adopt multiple modes such as spring lock collar, the ring-like fixed ring in garden.During use garden ring-like fixed ring, locking boss 16 need be set on the outer circumference surface of its loam cake 5 and lower cover 6, the locking boss 16 that is provided with on the annular groove 14 of the band opening 15 that is provided with on the ring-like fixed ring in garden and loam cake 5 and the lower cover 6 is complementary; The ring-like fixed ring in this garden can be one, but generally an effect respectively is set for well with two ends after loam cake 5 and lower cover 6 are involutory.Locking boss 16 on opening on the ring-like fixed ring in garden 15 and loam cake 5 and the lower cover 6 is aligned, and rotating a certain angle after being inserted in can be involutory fixing with loam cake 5 and lower cover 6.Can also be provided with the projection 13 of extending on the neighboring of the ring-like fixed ring in garden, in order to rotate the ring-like fixed ring in garden easily along its axis direction.

During air line 1 inflation, air pressure acts directly on the diaphragm 4 by the perforate on the pipeline 2, and diaphragm 4 is heaved slightly, and eyelet 3 opens and exhausted air carries out aeration, thereby reaches aeration and the purpose that spreads oxygenation in sewage.When stopping air feed, air line 1 internal pressure descends, diaphragm 4 resiliences, eyelet 3 is closed gradually under the effect of screen resilience and uplift pressure difference, after the air pressure completely dissolve, under the rebound effect of hydraulic pressure and barrier film 2, barrier film 2 restores to the original state, and its eyelet closure has also prevented to be blocked by mud.
