Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited only to this.
Embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of plate-type micro-pore aerator shown in Figure 5, mainly by the aerator body 3 of hollow and both ends open and be arranged on the diaphragm 1 of aerator body 3 upper port and the diffuser 6 of lower port forms, on described diaphragm 1, be provided with some micropores 102, between described aerator body 3 and diffuser 6, be provided with vacuum breaker 4, diaphragm 1 also is connected with non-return body 103, directly over the vacuum breaker 4 that non-return body 103 is positioned at away from an end of diaphragm 1, the zone of non-return body 103 between diaphragm 1 and vacuum breaker 4, diaphragm 1 be shaped as ellipse shape or square plate shape two ends add semi-circular plate shape.
Described vacuum breaker 4 inwalls are equipped with by removable pin 402 can be around the non-return flap 401 of removable pin 402 axis rotations.
On the outer wall of described diffuser, be provided with O type circle sealing groove, be provided with O type circle in O type circle circle sealing groove.
Vacuum breaker 4 is set can flow backwards by effective means sewage.Diaphragm 1 sealing is arranged on an end of aerator body 3, and diaphragm 1 is set to a micro-convex profile, increases the surface-area of diaphragm 1.Diffuser 6 is by vacuum breaker 4 and aerator body 3 internal communication, and air can pass through these parts successively, finally by the micropore 102 on diaphragm 1, enters in sewage.
In described vacuum breaker 4, be provided with removable pin 402, the non-return flap 401 of flexible movement is installed on described removable pin 402.Under the effect of pressure, the turning direction of non-return flap 401 changes.
On the outer wall of described diffuser 6, be provided with O type circle sealing groove 5, be provided with O type circle in O type circle circle sealing groove 5.Can increase stopping property, strengthen simultaneously and being connected that air is responsible for.
The periphery of described diaphragm 1 is provided with diaphragm chimb 101, and diaphragm 1 contacts with aerator body 3 by diaphragm chimb 101.Adopt diaphragm chimb 101 to make sealing effectiveness better, and diaphragm 1 can not be bonded together with aerator body 3.
Also comprise that an end is arranged on diaphragm 1 top, the fixing diaphragm of the other end and aerator body 3 compresses cover 2.Diaphragm compresses cover 2 and can make diaphragm 1 tightly be fixed on aerator body 3, can not come off due to the pressure change in use procedure.
Principle of work of the present utility model: the diffuser 6 of micro-hole aerator is connected with the air supervisor, air enters in aerator by diffuser 6, air-flow upwards pushes away non-return flap 401 around removable pin 402, then air enters in the aerator air storing cavity, micropore 102 unlatching protruding upward of diaphragm 1, diaphragm 1 is separated into micro-bubble by even air and enters into water body, has increased the contact area of bubble and water, dissolved oxygen, greatly improve the meltage of oxygen in water fast.When blower fan cut air feed, the blast main internal pressure descends, and non-return flap 401 moves downward, and in the aerator body cavity, forms enclosed space, and the micropore 102 of diaphragm 1 shrinks closes, and effectively prevents the phenomenon that sewage flows backwards.Non-return flap preferred rubber material circular slab.
In addition, the shape of diaphragm 1 is designed to ellipse shape to the utility model or square plate shape two ends add semi-circular plate shape, can effectively increase its area, increases aeration area.
In addition, after preventing that removable pin 402 from damaging, the phenomenon that sewage flows backwards occurs, the non-return body 103 that the utility model increases can also effectively seal the passage of vacuum breaker 4, and its principle is, when blower fan stops air feed, the blast main internal pressure descends, and non-return body 103 moves downward the obstruction check valve passage, in the aerator body cavity, forms enclosed space, the micropore 102 of diaphragm 1 shrinks closes, and effectively prevents the phenomenon that sewage flows backwards.With this, form the design of Double reverse-proof stream, its structure is more reliable.
Take aforesaid way, just can realize preferably the utility model.
