Abstract
The invention relates to a micropore aerator with large-area diaphragm with center and periphery doubly fixed. The micropore aerator comprises a supporting plate, wherein the center of the supporting plate is provided with an air vent; connecting ribs are uniformly distributed on the diameter of the supporting plate; the diaphragm with extension compensation edges is arranged on the supporting plate; and a limit screw rod is subjected to injection molding in the center of the diaphragm, passes through the air vent in the supporting plate and is inserted into a limit pore in a non-return device. The micropore aerator has the advantages of uniform aeration, tearing resistance, long service life and large aeration area.
Description
Technical field
The present invention relates to water treatment and aquaculture oxygenation microporous diaphragm plate-type aerator, particularly a kind of aerator diaphragm center fix, aeration evenly, long service life, micro-hole aerator that aeration area is large.
Background technology
The diaphragm type aerator is applied in water treatment and aquaculture, supplies with oxygen replenishing equipment a kind of of required air (oxygen), and because its diffusion bubble is little, gas-water contact is large, and the advantage that the oxygen exchange rate is high is used very extensive at present.Basic structure is pneumatic tube, the supporting tube be connected with pneumatic tube, plate, dish, spherical crown etc., is wrapped in the diaphragm on supporting tube, plate, dish, spherical crown, generally adopts its mixing materials such as terpolymer EP rubber, silicon rubber, plastics to make.Air during work (or oxygen) is sprayed by the micropore of diaphragm, and then water body is carried out to oxygen supply.
But there are a lot of problems in current aerator.For example, the platy fine bubble 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 during work, convex is heaved, and the center aeration rate is large, and the surrounding aeration rate is little; Aeration pressure and aeration rate all concentrate on the central authorities of plate-type aerator, cause aerator central part pressure greatly, easily to tear strain, and diaphragm periphery aeration is insufficient, and that peripheral diaphragm area account for the ratio of whole diaphragm area is very large, 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, efficiency 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 double-deck fixing, the aeration of a kind of center and surrounding evenly, anti tear, long service life, microporous diaphragm aerator that aeration area is large.
Technical scheme: in order to solve the problems of the technologies described above, the double-deck fixedly big area microporous diaphragm aerator of center of the present invention and surrounding, it comprises back up pad, at this back up pad center, be provided with ventilating pit, and on this back up pad diameter equally distributed dowel, on described back up pad, be provided with the diaphragm that band extends the compensation limit, at this diaphragm center injection moulding one Limit screw, the ventilating pit that this Limit screw passes on described back up pad inserts the spacing hole on check device.
Described Limit screw is welded in the middle of described back up pad.
Described check device is located at the air inlet port.
The diameter of described aerator is 215mm-400mm.
On described diaphragm, be provided with micropore.
Aeration membrane is wrapped in the edge of support, with conventional peripheral fixed form and aerator diaphragm periphery, extends the compensation position and is fixed together.During aerator work, gas is washed vacuum breaker open, the hole between intake ducting and stiffening web, and in the cavity zone formed between bracing frame and aeration membrane of directly entering, whole cavity, gaseous tension equates, last gas is extruded by the micropore on diaphragm.Because gas contacts with whole diaphragm area, and gas pressure is suitable everywhere, aerator is uniform aeration everywhere; Whole diaphragm applied force is even, has protected diaphragm tear and strain because of what unbalance stress caused, has guaranteed the longest working life.To account for whole diaphragm area ratio large 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 aeration equipment, reduce energy consumption.
Finally, because above purpose realizes, can produce the aerator of super-large diameter, the diameter of acceptor center air inlet restriction can only not be 215mm, 260mm, 300mm yet, and the diameter of aerator can accomplish that 320mm, 350mm are even larger.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: utilize Limit screw that diaphragm, back up pad are fixed into and are integrated, reach the fixing purpose in center; The fixing effect of surrounding is played on extension compensation limit on diaphragm; Gas enters from the space between stiffening web on back up pad, has protected diaphragm tear and strain because of what unbalance stress caused, has improved work-ing life; To account for whole diaphragm area ratio large 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 aeration equipment, reduce energy consumption.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the double-deck fixedly big area microporous diaphragm aerator of center of the present invention and surrounding, it comprises back up pad 1, at this back up pad 1 center, be provided with ventilating pit 2, and on this back up pad 1 diameter equally distributed dowel 3, on described back up pad 1, be provided with the diaphragm 4 that band extends the compensation limit, at these diaphragm 4 center injection moulding one Limit screws 5, this Limit screw 5 passes the spacing hole 7 that the ventilating pit 2 on described back up pad 1 inserts on check device 6; Described Limit screw 5 is welded in the middle of described back up pad 1; Described check device 6 is located at air inlet port 8; The diameter of described aerator is 215mm-400mm; On described diaphragm 4, be provided with micropore 9; During aerator work, gas is washed vacuum breaker open, the hole between intake ducting and stiffening web, and in the cavity zone formed between bracing frame and aeration membrane of directly entering, whole cavity, gaseous tension equates, last gas is extruded by the micropore on diaphragm.Because gas contacts with whole diaphragm area, and gas pressure is suitable everywhere, aerator is uniform aeration everywhere; Whole diaphragm applied force is even, has protected diaphragm tear and strain because of what unbalance stress caused, has guaranteed the longest working life.To account for whole diaphragm area ratio large 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 aeration equipment, reduce energy consumption.The present invention utilizes Limit screw that diaphragm, back up pad are fixed into and are integrated, and reaches the fixing purpose in center; The fixing effect of surrounding is played on extension compensation limit on diaphragm; Gas enters from the space between stiffening web on back up pad, has protected diaphragm tear and strain because of what unbalance stress caused, has improved work-ing life; To account for whole diaphragm area ratio large 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 aeration equipment, reduce energy consumption.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
