Abstract
The utility model relates to a micro-porous aerator which comprises a main body, a non-return valve, a membrane sheet, a telescopic ring, a pressing cover and a wedge sheet; the non-return valve is arranged in an air inlet; the non-return valve is sequentially provided with the membrane sheet and the telescopic ring which are fixedly connected through the pressing cover finally; the non-return valve is internally provided with a steel ball; an O-shaped seal ring is sleeved on the non-return valve; the wedge sheet and the main body are connected to a ventilation pipeline in a matched mode; and the membrane sheet is provided with a micro pore. According to the utility model, sewage can be prevented from entering the ventilation pipeline system effectively by adopting the non-return valve, and the service life of the product is prolonged; and the telescopic ring has good antiskidding and sealing effect.
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; But in the life-time service process; Because multiple is constantly worked, gland is loosening easily, influences the operation of equipment; 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 main body, vacuum breaker, diaphragm, expansion ring, gland and key; Said vacuum breaker is arranged in the inlet mouth; On said vacuum breaker, be provided with diaphragm and expansion ring successively, be fixedly connected through said gland at last; Be provided with steel ball in the said vacuum breaker, on this vacuum breaker, be with the O RunddichtringO; Said key and said main body are supporting to be connected on the breather line; On said 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; Use expansion ring to play good anti-skidding sealing function.

1, main body; 2, vacuum breaker; 3, diaphragm; 4, expansion ring; 5, gland; 6, key; 7, inlet mouth; 8, steel ball; 9, O RunddichtringO; 10, breather line; 11, micropore
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As illustrated in figs. 1 and 2, the utility model comprises main body 1, vacuum breaker 2, diaphragm 3, expansion ring 4, gland 5 and key 6; Said vacuum breaker 2 is arranged in the inlet mouth 7; On said vacuum breaker 2, be provided with diaphragm 3 and expansion ring 4 successively, be fixedly connected through said gland 5 at last; Be provided with steel ball 8 in the said vacuum breaker 2, on this vacuum breaker 2, be with O RunddichtringO 9; Said key 6 and said main body 1 supporting being connected on the breather line 10; On said diaphragm 3, be provided with micropore 11.The utility model adopts vacuum breaker can effectively stop sewage to get into ventiduct system, the work-ing life of having improved product; Use expansion ring to play good anti-skidding sealing function.
The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
