Abstract
The invention relates to a large-area diaphragm type microporous aerator which comprises a supporting plate, wherein through-holes are evenly formed on the supporting plate; a position limiting hole is formed at the center of the supporting plate; a diaphragm with an extended compensating edge is arranged on the upper surface of the supporting plate; and a positioning screw rod, which is injection-molded at the center of the diaphragm, passes through the position limiting hole to fixedly connect the supporting plate and the diaphragm through a fixing nut. The large-area diaphragm type microporous aerator has the advantages of even aeration, tear resistance, long service life, large aeration area and high utilization rate.
Description
Technical field
The present invention relates to water treatment and the microporous diaphragm plate-type aerator is used in the aquaculture oxygenation, particularly a kind of aerator diaphragm center fixation, aeration evenly, long service life, micro-hole aerator that aeration area is big.
Background technology
The diaphragm type aerator is applied in water treatment and the aquaculture, supplies with oxygen replenishing equipment a kind of of required air (oxygen), and because of its diffusion bubble is little, WGC is big, and the advantage that the oxygen exchange rate is high is used very extensive at present.Substruction is pneumatic tube, the supporting tube that is connected with pneumatic tube, plate, dish, spherical crown etc., is wrapped in the diaphragm on supporting tube, plate, dish, the spherical crown, generally adopts its mixing materials such as terpolymer EP rubber, Zylox, plastics to process.Air during work (or oxygen) is sprayed by the diaphragm-operated micropore, and then water body is carried out oxygen supply.
But there are a lot of problems in present aerator.For example, disc type micro-hole aerator area is limited, and diameter is little, aeration is inhomogeneous, and the aeration rubber diaphragm only is fixed on the disk fixed support at periphery, and convex is heaved during work, and the center aeration rate is big, and aeration rate is little all around; Aeration pressure and aeration rate all concentrate on the central authorities of plate-type aerator; Cause aerator central part pressure big, be prone to tear strain, and diaphragm periphery aeration is insufficient, and that peripheral diaphragm area accounts for the ratio of whole diaphragm area is very big; Thereby whole diaphragm utilization ratio is low, and the aeration effect is undesirable.Be that the aerator diameter is little, the aeration area utilization ratio is low, aeration weak effect, efficient be low, the utilization ratio of oxygen, the shortcoming that energy consumption is high.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, provide a kind of center and double-deck fixing all around, aeration evenly, anti tear, long service life, aeration area is big, utilization ratio is high big area microporous diaphragm aerator.
Technical scheme: in order to solve the problems of the technologies described above; Big area microporous diaphragm aerator of the present invention, it comprises back up pad, on said back up pad, evenly is provided with communicating pores; Be provided with spacing hole at said back up pad center; On said back up pad, be provided with the diaphragm that band extends the compensation limit, at said diaphragm center injection moulding one location screw rod, this positioning screw passes said spacing hole and is fixedly connected back up pad with diaphragm through set screw nut.
Inlet mouth place at said aerator is provided with check device.
Said positioning screw is welded in the middle of the said back up pad.
The shape of said communicating pores is circular, square or curve arc.
On said diaphragm, be provided with micropore.
The diameter of said aerator is 215mm-350mm.
Do not limit with the support plate edge fixed form around the said diaphragm, need only fixation, open the hole of even perforation on the back up pad; Purpose be increased induction trunk and with the aeration membrane contact area, the large impact power that causes when avoiding the air inlet of diaphragm center, thus make the suffered surging force of diaphragm and pressure identical everywhere; Protected diaphragm because of tearing of causing of unbalance stress with strain; Prolong diaphragm-operated work-ing life, also increased diaphragm periphery utilization ratio simultaneously, strengthened the aeration effect; Improve aeration efficient, reduced energy consumption.
Aerator diaphragm center injection moulding one location screw rod; Positioning screw passes the pilot hole of aerator back up pad, with nut aerator diaphragm and aerator back up pad is fixed up, and reaches between aerator diaphragm center and the aeration board to connect as one with solid screw; Play the fixedly aerator diaphragm and the bracing frame effect of connection on the one hand; Sealed in fact aerator diaphragm-operated center on the other hand, stoped gas to the aeration membrane center, protection diaphragm center is avoided big surging force and is prone to tear strain.At last, solid screw rod has been shut the passage that gas directly rises to the diaphragm center, force gas toward around aerator diaphragm periphery move, make the pressure everywhere of whole aeration membrane, aeration is more even.Simultaneously, to account for whole diaphragm area ratio big because of aerator periphery area, the raising of aerator periphery area utilization, thus improved aeration area utilization ratio, aeration effect and the oxygen transfer efficiency of whole diaphragm aerator, cut down the consumption of energy.
Owing to the realization of above purpose, also can produce the aerator of super-large diameter, the diameter of acceptor center air inlet restriction can only not be 215mm, 260mm, 300mm, the diameter of aerator can be accomplished 320mm, 350mm.
Beneficial effect: the present invention compared with prior art; Its remarkable advantage is: be employed in and open communicating pores on the back up pad, increased induction trunk and with the contact area of aeration membrane, prolonged diaphragm-operated work-ing life; Also increase simultaneously diaphragm periphery utilization ratio; Strengthen the aeration effect, improved aeration efficient, reduced energy consumption; At aerator diaphragm center injection moulding one location screw rod, strengthened strength of joint, stoped gas to the aeration membrane center simultaneously, protection diaphragm center is avoided big surging force and is prone to tear strain.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Like Fig. 1, Fig. 2 and shown in Figure 3; Big area microporous diaphragm aerator of the present invention, it comprises back up pad 1, on said back up pad 1, evenly is provided with communicating pores 2; Be provided with spacing hole 3 at said back up pad 1 center; On said back up pad 1, be provided with the diaphragm 4 that band extends the compensation limit, at said diaphragm 4 center injection mouldings one location screw rod 5, this positioning screw 5 passes said spacing hole 3 and is fixedly connected back up pad 1 with diaphragm 4 through set screw nut 6; Inlet mouth 7 places at said aerator are provided with check device 8; Said positioning screw 5 is welded in the middle of the said back up pad 1; The shape of said communicating pores 2 is circular, square or curve arc; On said diaphragm 4, be provided with micropore 9; The diameter of said aerator is 215mm-350mm; Aerator diaphragm 4 center injection mouldings one location screw rod 5; Positioning screw 5 passes the spacing hole 3 of aerator back up pad 1; With nut 6 aerator diaphragm 4 and aerator back up pad 1 are fixed up; Reach between aerator diaphragm 4 centers and the aerator back up pad 1 and connect as one, play the fixedly effect of aerator diaphragm 4 and back up pad 1 that connects on the one hand with solid positioning screw 5, on the other hand envelope in fact the center of aerator diaphragm 4; Stoped gas to aeration membrane 4 centers, protection diaphragm 4 centers are avoided big surging force and are prone to tear strain.The present invention is employed in and opens communicating pores on the back up pad, increased induction trunk and with the contact area of aeration membrane, prolonged diaphragm-operated work-ing life, also increase diaphragm periphery utilization ratio simultaneously, strengthened the aeration effect, improved aeration efficient, reduced energy consumption; At aerator diaphragm center injection moulding one location screw rod, strengthened strength of joint, stoped gas to the aeration membrane center simultaneously, protection diaphragm center is avoided big surging force and is prone to tear strain.
