Abstract
The invention discloses a buckle membrane type microporous aerator, and relates to a water treatment membrane type aerating device. The aerator comprises a pallet, an elastic membrane with micropores and a sealing hoop, wherein the sealing hoop of the aerator is an open circular ring of which the cross section is L-shaped; and one free end of two long edges of the open circular ring is designed into a clamping hook, and the other free end of the two long edges of the open circular ring is designed into a clamping groove matched with the clamping hook. By buckle type lap joint, the hoop is easy and convenient to assemble and disassemble, and the fastening force between the hoop and the membrane as well as between the hoop and a support frame is greatly increased to form complete air-tight seal; and in addition, pressure born by the membrane at the tight holding and connecting position of a sealed hoop can be dispersed, the elastic membrane can be protected, and the service life of an aeration head can be prolonged.
Description
Technical field
The present invention relates to a kind of membrane type aerating apparatus of water treatment, especially a kind of membrane-type microporous aerator of snap-type.
Background technology
Generally all adopting the membrane type aerating apparatus to be used for the aeration of water treatment on the market at present, this device aeration is even, can produce very fine and closely woven bubble, effectively increases the area that bubble contacts with water, has improved the efficient of dissolved oxygen greatly, is widely used.Traditional membrane type aerator, the sealing method between its aeration membrane and the pallet differs, and sealing effectiveness is not good, and dismounting is also inconvenient, causes a large amount of gases to reveal from the side, and aeration efficient is reduced.Chinese patent ZL98226099.7 discloses a kind of aerator of spherical cap-shaped structure, and its spherical supporting seat and diaphragm are held tightly and on supporting seat, formed hermetic seal by tightening up hoop, has roughly solved the problem that gas is revealed from the side; But because hoop is mounted in the spherical crown below, hoop is that the cross section is the closed annulus of square or long strip shape, receives to install restriction; Its degree of holding tightly is not too large, and when charging into air-flow, it is stronger that diaphragm is held the pressure that bears the junction tightly at hoop; Hoop is relaxed easily; The rubber diaphragm at this position also is prone to weak, can't form hermetic seal completely, can make the micropore distortion on the diaphragm in addition; Under the long term operation environment, also cause tearing of rubber diaphragm easily, influence the practical life of aerator.
Summary of the invention
The objective of the invention is to deficiency, a kind of snap-type membrane-type microporous aerator of easy accessibility is provided, can make to form sealing fully between pallet and elasticity aeration membrane, and increased the work-ing life of elasticity aeration membrane effectively to prior art.Main innovation is the hoop of fastening diaphragm and pallet is designed to the open type annulus that the cross section is the L type, and on two long limit free ends of open type annulus, an end is designed to grab; One end is designed to draw-in groove, during installation, the long limit of L type hoop is placed on the place, outer ring of the diaphragm and the pallet of aerator; Minor face is overlying on membrane surface, simultaneously the grab draw-in groove overlap joint on the long limit of two free ends of open type annulus is formed a fastening hoop, realizes the powerful power of holding tightly; Form hermetic seal completely, simultaneously, because the hoop sealing surface area is bigger; The diaphragm that has disperseed to hold the junction tightly bears pressure, has protected flexible sheet.
The present invention realizes through following technical scheme: snap-type membrane-type microporous aerator; Hoop is used in the flexible sheet, the sealing that comprise pallet, have a micropore; It is characterized in that hoop is that the cross section is the open type annulus of L type; On two long limit free ends of open type annulus, an end is designed to grab, the draw-in groove that an end is designed to connect with it.During aeration work; Pressure air gets between elasticity aeration membrane and the pallet through the ventpipe of aerator, under the effect of supply gas pressure, is heaved former being close to the elasticity aeration membrane integral body of pallet; Owing to used the buckle-type sealing hoop of cross section as the L type; The side and the upper surface at elasticity aeration membrane edge can both be fastened on the pallet, make elasticity aeration membrane edge receive good protection and fastening, prevent that the aeration membrane edge from answering pressure and tear or be out of shape.
The long limit of the hoop of said L type is provided with several long strip type projections, leaves spacing between the minor face of long strip type projection and hoop, and said gap length equals the thickness of flexible sheet.In when assembling, the flange flange of elasticity aeration membrane is embedded in the long strip type projection and the spacing between minor face of hoop, guarantee to form sealing effectiveness completely, its assembling is also convenient simple simultaneously.
The check cavity that communicates with ventpipe is set up on the ventpipe top of pallet, in the described check cavity check ball is arranged, and the diameter of check ball is greater than the ventpipe aperture.Adopt the pallet of this structure, can be after aerator quit work, check ball is blocked ventpipe, prevents that effectively water body from pouring in down a chimney, and prolongs the work-ing life of aerator.
The present invention uses hoop structure through sealing structure; Utilize the overlap joint of buckle-type, not only let the hoop installing/dismounting simple and convenient, and the fastening force between itself and diaphragm and bracing frame is increased greatly; Form hermetic seal completely; Can also disperse to seal hoop in addition and hold the diaphragm of junction tightly and bear pressure, the protection flexible sheet prolongs work-ing life of aeration head.

Embodiment
Embodiment 1, snap-type membrane-type microporous aerator, comprise pallet 3, have micropore flexible sheet 2, the sealing with hoop 1; It is the open type annulus of cross section as the L type that hoop 1 is used in sealing; On two long limit free ends of open type annulus, an end is designed to the draw-in groove 14 that grab 13, one ends are designed to connect with it.During manufacturing flexible sheet 2 is coated on the pallet 3, will seals then with hoop 1 and hold tightly along pallet 3 edge buckles.
Embodiment 2, reference implementation example 1, and the long limit 12 of the hoop 1 of L type is provided with several long strip type projections 11, and 15 of the minor faces of long strip type projection 11 and hoop leave spacing, and said gap length equals the thickness of flexible sheet 2.In when assembling, the flange flange of elasticity aeration membrane 2 is embedded in the spacing of 15 of long strip type projection 11 and minor faces of hoop, guarantee to form sealing effectiveness completely.
