Abstract
The utility model relates to a microporous aerator which comprises a threaded base, a check valve, a diversion support plate, a rubber diaphragm, a threaded gland and a wedge plate, wherein the check valve is arranged on an air inlet of the base; and the diversion support and the rubber diaphragm are sequentially arranged on the check valve, and finally fixed and connected through the threaded gland. The check valve is adopted for effectively preventing the sewage from flowing into a ventilation pipeline system, and the service life of the product is prolonged.
Description
Technical field
The utility model relates to a kind of aerating apparatus of WWT, is specifically related to a kind of efficient micro-hole aerator.
Background technology
In the method for disposing of sewage, a kind of efficient ways during biochemical treatment, not only economy but also easy.In order to improve its treatment effect, in the sewage that will handle, sufficient dissolved oxygen arranged, to promote the oxidizing reaction in the sewage.Aerator is the main device of oxygen supply in sewage.Existing aeration head produces bigger bubble in practical application, thereby the contact area of bubble and water is little, and it is slower that oxygen is dissolved in the speed of water.General micro-hole aerator is made up of elements such as chassis, supporting plate, gland and rubber air distribution plates, and the chassis is communicated with ventilator trunk.During use, air at first gets in the chassis, behind supporting plate, discharges the micropore from the rubber air distribution plate then to be diffused into to form the bubble effusion water surface in the sewage, to reach in sewage the purpose towards oxygen; When but system stops using, do not have pressure in the system, mud and foreign material regular meeting are deposited on the rubber air distribution plate, and the micropore above stopping up, even can get in the ventiduct system, and influence is used next time, thereby influences the total system works better.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art, the micro-hole aerator of a kind of intensity height, long service life, good seal performance to be provided.
Technical scheme: the described micro-hole aerator of the utility model comprises threaded base, vacuum breaker, water conservancy diversion support plate, rubber diaphragm, union (screwed)bonnet (UB and wedge; On said base air inlet port, be provided with said vacuum breaker; On said vacuum breaker, be provided with said water conservancy diversion support plate, rubber diaphragm successively, be fixedly connected through said union (screwed)bonnet (UB at last.
Have air channel at said water conservancy diversion support plate edge.
Said wedge and said base are supporting to be connected on the breather line, is provided with O type circle at this place, breather line air outlet.
On said rubber diaphragm, be provided with micropore.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: adopt vacuum breaker can effectively stop sewage to get into ventiduct system, the work-ing life of having improved product.
