Description
Technical field
The utility model relates to waste water control field, is specifically related to a kind of antifouling aerator.
Background technology
In the method for biochemical treatment sewage, aerator is the main device to oxygen supply in sewage.In actual applications, use more aeration head to produce larger bubble, thereby the contact area of bubble and water is little, it is slower that oxygen is dissolved in the speed of water.Breather hole aerator after improvement has less bubble, accelerated the speed that oxygen is dissolved in water.
No matter but be common aerator, or breather hole aerator is provided with ventilator trunk, all needs to prevent that mud and foreign material from entering in ventilator trunk.General breather hole aerator is to be comprised of elements such as chassis, supporting plate, gland and rubber air distribution plates, and chassis is communicated with ventilator trunk.During use; first air enters in chassis; then after supporting plate, the breather hole from rubber air distribution plate is discharged to be diffused into and in sewage, is formed the bubble effusion water surface, to reach to the object of rushing oxygen in sewage, but when system is stopped using; in system, there is no pressure; mud and foreign material often can be deposited on rubber air distribution plate, and stop up breather hole above, even can enter in ventiduct system; impact is used next time, thereby affect whole system, normally works.
Existingly prevent that mud and the foreign material method in ventilator trunk of entering from being that the inlet mouth place of ventiduct system arranges valve means.Inlet mouth place at ventiduct system arranges valve means, can reduce mud to a certain extent and foreign material enter ventiduct system, but because the closure of valve means need to realize under the effect of pressure difference, the generation of the pressure difference at inlet mouth place also needs certain hour, simultaneously, rubber air distribution plate is the breather hole of opening, is difficult at inlet mouth place, produce immediately the quick closedown that larger pressure difference realizes valve means.Therefore,, in the process of closing at valve body, still have mud unavoidably and foreign material enter ventiduct system.Therefore further perfect to breather hole aerator.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of antifouling aerator, can reduce mud in a large number and foreign material enter ventiduct system, is more conducive to aerating system and normally works, and effectively extends the work-ing life of aerator.
For reaching above object, the technical scheme that the utility model is taked is: a kind of antifouling aerator, comprise aeration board, water conservancy diversion support plate, bearing, air-supply duct, aeration board comprises the alveolar disk that is provided with at least one breather hole, aeration board and water conservancy diversion support plate are socketed on bearing by gland, the bottom of air-supply duct is provided with key, bearing is fixed on air-supply duct by key, the top of air-supply duct has the first inlet mouth, the inside of the first inlet mouth is provided with vacuum breaker, between the first inlet mouth inwall and vacuum breaker, be provided with O-ring seals, water conservancy diversion support plate has the second inlet mouth with the corresponding part of the first inlet mouth, described the second inlet mouth bottom correspondence is provided with a shell fragment, described shell fragment comprises active side and fixation side, described fixation side is fixedly connected with the second inlet mouth bottom, active side is positioned at the second inlet mouth bottom margin.
On the basis of technique scheme, described shell fragment adopts rubber or plastics to make.
On the basis of technique scheme, the arranged outside of described alveolar disk has wear ring.
On the basis of technique scheme, the diameter of described aeration board is 220～320mm.
On the basis of technique scheme, the diameter of described aeration board is 280mm.
Compared with prior art, the utility model has the advantage of:
(1) the utility model, except being provided with vacuum breaker, is also provided with shell fragment at inlet mouth place, and shell fragment comprises active side and fixation side, and fixation side is fixedly connected with the second inlet mouth bottom.When stopping using aerating system, no longer, to input air in air-supply duct, now, because shell fragment very Qian is very light, the variation sensing of draught head is greater than to vacuum breaker, the active side of shell fragment can, before closure of check ring, be retracted fast in inlet mouth.
After shell fragment active side is retracted, form sealing state, can stop mud and foreign material to enter air-supply duct, simultaneously, the air reducing between bearing and water conservancy diversion support plate enters water from aeration board, like this, can reduce the poor time of mineralization pressure, closure of check ring time shorten, therefore, can better prevent that mud and foreign material from entering in air-supply duct, more be conducive to aerating system and normally work, effectively extend the work-ing life of aerator.
(2) shell fragment is convenient to change, easy to use.

In figure: 1-aeration board, 2-vacuum breaker, 3-shell fragment, 4-O shape sealing-ring, 5-water conservancy diversion support plate, 6-gland, 7-bearing, 8-air-supply duct, 9-key, 10-breather hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, the aeration board 1 that the antifouling aerator in the utility model embodiment comprises, water conservancy diversion support plate 5, bearing 7, air-supply duct 8.On aeration board 1, have and comprise the alveolar disk that is provided with at least one breather hole 10, porose disc arranged outside has wear ring.Aeration board 1 is connected on bearing 7 by gland adapter sleeve with water conservancy diversion support plate 5, and the bottom of air-supply duct 8 is provided with key 9, and bearing 7 is fixed on air-supply duct 8 by key 9.
The top of air-supply duct 8 has the first inlet mouth, is provided with between vacuum breaker 2, the first inlet mouth inwalls and vacuum breaker 2 and is provided with O-ring seals 4 in the first inlet mouth.
On water conservancy diversion support plate 5, have the second inlet mouth with the corresponding part of the first inlet mouth, in the second inlet mouth bottom correspondence, be provided with a shell fragment 3, shell fragment 3 comprises active side and fixation side, and fixation side is fixedly connected with the second inlet mouth bottom, and active side is positioned at the second inlet mouth bottom margin; Shell fragment 3 in the utility model adopts rubber or plastics to make.
The diameter of the aeration board 1 in the utility model is 220～320mm, more preferably 280mm.
Principle of work of the present utility model:
During use, in air-supply duct 8, pass into air, vacuum breaker 2 is opened, air-flow is opened shell fragment 3, the active side of shell fragment 3 is advanced the second inlet mouth inner by air-flow, air-flow enters in the space of water conservancy diversion support plate 5 and aeration board 1 formation, by the breather hole 10 in aeration board 1, enters in water, and system is normally worked.
While stopping using, no longer to input air in air-supply duct 8, now, due to shell fragment, 3 Hen Qian are very light, the variation sensing of draught head is greater than to vacuum breaker 2, and the active side of shell fragment 3 can, before vacuum breaker 2 cuts out, be retracted into the not state of blowing air fast in the second inlet mouth.
After the active side of shell fragment 3 is retracted, form sealing state, not only can stop mud and foreign material to enter air-supply duct 8, and the air that can reduce between bearing 7 and water conservancy diversion support plate 5 enters in water from aeration board 1, can shorten the poor time of mineralization pressure, 2 turn-off times of vacuum breaker shorten, and can better prevent that mud and foreign material from entering in air-supply duct 8.
The utility model is not only confined to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a utility model or akin technical scheme, all within its protection domain.
