Abstract
The utility model relates to an improvement of an expanding micro hole diaphragm aerator for water treatment. The utility model is characterized in that an aerating diaphragm and a support pallet adopt a truncated cone shape structure, and center positions of the diaphragm and the pallet are provided with a positioning bolt which is lifted by a positioning diaphragm. When the aerator works, an excessive expansion of the diaphragm can be greatly reduced, thereby not only improving a tearresistant of the aerating diaphragm, prolonging a service life of the diaphragm, but also effectively guaranteeing a close attachment between the aerating diaphragm and a diaphragm bearing seat after gas is stopped, and greatly improving a block-water performance.
Description
Technical field
Utility model is about water treatment being used the improvement that can open the microporous membrane aerator.
Background technology
The microporous membrane opened of oxygenic aeration aerator in water has two kinds of structure formations usually, and a kind of is the plane tray type structure as described in the Chinese patent 92205599, and a kind of is protruding ball collar shape structure as described in the Chinese patent 98226099.But the microporous membrane the opened aerator of these two kinds of structures, because having the diaphragm of placing restrictions on, diaphragm center or top do not stretch, when aeration is worked, the excessive expansion of diaphragm-operated makes that the diaphragm unit elongation is relatively large, and long term operation easily causes diaphragm tired lax, stopping the aeration rear film can not reply fully to restore and closely connectedly support pallet in diaphragm, micropore just can not complete closed, flows backwards through the aeration membrane micropore and enters aerator thereby easily produce water body, influences aerating system efficient and safe operation; Secondly, the expansion that aeration membrane is big stretches and also causes diaphragm to be torn easily, influences work-ing life.Plane tray type structure aerator in addition, stop aeration work after, in the water mud easily precipitation accumulate in the aerator membrane surface, the resistance when having increased aeration once more strengthens air supply intensity and causes aeration membrane to damage easily.Secondly, generally can open the microporous membrane aerator, adopt to the diaphragm air feed to fling top-opening type, this top-opening type air feed that flings easily causes over against the suffered surging force of the diaphragm at air supply duct position and stretches greater than other positions of diaphragm, also can cause this position diaphragm easily to damage easily at other positions.Above-mentioned defective is particularly outstanding in the major diameter aerator.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, can effectively place restrictions on the diaphragm overdistension when a kind of aeration is provided and stretch, and the diaphragm expansion stretches little, is difficult for breaking the microporous membrane the opened aerator of long service life.
The utility model purpose realizes, main improvement is to change the aeration membrane of plane tray type structure or sphere domes and diaphragm support pallet into circular platform type structure protruding upward, and be provided with diaphragm in circular platform type diaphragm and supporting bracket disk center and expand spacing take-up device, thereby reduced transition expansion and the stretching of diaphragm in aeration process, thereby reduce diaphragm fatigue strength, reach can effectively reply after diaphragm stops aeration in often using closely connected in the supporting bracket panel surface.Specifically, utility model can be opened the microporous membrane aerator, comprise the elasticity aeration membrane that has micropore, aeration membrane supports pallet and to the air supply channel of aeration membrane air feed, said aeration membrane Bao Meng is in the supporting bracket panel surface, it is characterized in that said aeration membrane and supporting pallet is circular platform type, and diaphragm and pallet centre have places restrictions on the limited bolt that diaphragm lifts.
The described circular platform type of utility model obviously enough is different from the spherical crown domes for forming, and is meant that the plane is at least more than or equal to 1/2 of aeration membrane base diameter on the aerator.Utility model is to reduce the local assault power of air feed to aeration membrane, said air supply channel top is oblique outlet, pressure air can obliquely enter between diaphragm and support pallet in the gas distribution pipeline like this, avoided pressure breathing to fling diaphragm and caused the over-stressed fatigue of air inlet position diaphragm, even aeration membrane stressed.
The utility model aerator is owing to adopt the truncated cone-shaped structure, and increased the caging bolt of placing restrictions on top membrane expansion, thereby reduced aeration when work to the diaphragm-operated expansion that excessively stretches, the not only satisfied back aeration membrane of stopping the supple of gas or steam can remain the driving fit of being close to the diaphragm support seat, the big raising of block-water performance after aerator is stopped the supple of gas or steam, having prevented effectively that diaphragm-operated from leaking pours in down a chimney, and anti-this fragility of diaphragm is improved; 45 ° of inclined-plane air feed have avoided supply gas pressure that diaphragm-operated is directly impacted; Owing to do not lift during top membrane work, even there is a small amount of mud to accumulate after stopping the supple of gas or steam, can not increase the resistance when restarting yet, above-mentioned these technical measures have all effectively prolonged the work-ing life of aeration membrane.Support pallet and adopt 1 with the gas distribution pipeline " the internal thread special joint is connected; improved aerator and gas distribution pipeline strength of joint; overcome other aerators and adopted 3/4 " screw thread and gas distribution pipe connection, contact area is little, the shortcoming that ventilation back gas distribution pipeline is torn easily.
Below in conjunction with a specific embodiment, further specify utility model structure and working process.
Description of drawings

Fig. 2 looks up structural representation for Fig. 1.
Embodiment
Embodiment: referring to accompanying drawing, can open the microporous membrane aerator, have circular platform type support pallet 2 and similar shape to be close to the circular platform type mipor rubber aeration membrane 1 of supporting bracket panel surface, and be located at steam line 3 compositions of supporting bracket disk center, there is the tightening screw 4 of placing restrictions on the diaphragm expansion at the aerator center.Air supply duct is by some dowels 5 and pallet positioning and fixing, the upper table surface periphery is located in the air supply channel outlet, outlet 6 is 45 ° of tiltedly outlets, back taper pad 9 is arranged at tightening screw (limited bolt) bottom of being located in the parichnos, with the oblique gas off-take of the common composition of oblique outlet, the aerator mesa diameter is 1/2 of a base diameter, and the thickening of table top diaphragm.Truncated cone-shaped pallet base is inwardly shunk and is formed scrobicular ring in to downward liter, the aeration membrane bottom is also inwardly shunk and is extended to form the interior scrobicular ring limit identical with the pallet base downwards, one stainless steel elastic cuffs 7 supporting on the pallet indent ring, makes diaphragm bottom banding between diaphragm and pallet and forms hermetic seal.1 that is connected and fixed with gas-distribution pipe is arranged at the air supply channel bottom, and " interior or outside screw 8 is screwed on the gas distribution pipeline for aerator.
During work, pressure air is tiltedly exported by air supply channel by the distribution pipeline and enters between circular platform type aeration membrane and support pallet, under the supply gas pressure effect, thin side surface aeration membrane is heaved left supporting bracket dish formation one work distribution space, pressure air is by the even outwards diffused aeration of the micropore on the aeration membrane.Diaphragm central authorities are because the overdistension of diaphragm in aeration process placed restrictions in thickening and have tightening screw spacing and can not lift; After stopping the supple of gas or steam, the distribution space of working between diaphragm and support pallet disappears, and aeration membrane shrinks back and tightens up pressing in round platform supporting base surface under hydraulic pressure and self elastic recovery acting in conjunction.The embodiment of utility model, be not limited to the foregoing description, can suitable change be arranged on the utility model basic structure not departing from, can pass through hollow (band air passageways) bolt as aerator and being connected of gas distribution pipeline is connected with gas distribution pipeline, also can be connected with gas distribution pipeline by watt obvolvent of closing up and down that anchor ear such as wedge shape are pegged graft, the sealing of diaphragm and pallet can also be other obvolvent modes or the like.
