Technical Field

The utility model belongs to the technical field of sewage treatment, concretely relates to high-efficient sewage purification's micropore aerator.

Background

With the rapid development of society, the sewage problem is more and more serious, how to treat sewage rapidly and efficiently becomes the key of the problem, and the microporous aerator is the necessary equipment for blast aeration and oxygenation, and the structure of the aeration equipment and the oxygen transfer and aeration efficiency not only influence the biochemical treatment effect of sewage, but also influence the land occupation, investment and operating cost of a sewage farm.

Although the supporting tube is designed to support the aeration membrane to allow the air flow to directly enter the aeration layer, the problem that the air flow still needs to support the aeration membrane completely attached to the supporting tube is still solved, and the novel tubular microporous aerator still has large resistance and needs large air pressure and air volume, which results in high energy consumption. Although the micro-pores on the aeration membrane are improved into the S-shaped arc air holes, the breakage of the arc air holes at one position cannot cause the integral tearing of the aeration membrane, the tearing problem of the aeration membrane cannot be avoided, the aeration efficiency is low after the aeration membrane is torn, and the aeration membrane needs to be frequently replaced to cause the high cost problem. Meanwhile, the problem of pressure caused by different water depths is not solved, the pressure generated by different water depths is different, the water pressure presses the aeration membrane when the water depths are different, the air holes are opened by different air pressures and air volumes due to the designed linear air holes, the pressure needs to be accurately adjusted, the aeration holes cannot be opened to the optimal state, the aeration efficiency is low when the aeration holes are too small, and the aeration membrane can be torn when the aeration holes are too large. Therefore, the problems that the aeration membrane is easy to tear to bring low aeration efficiency, the aeration membrane needs to be frequently replaced to bring high cost, the aeration membrane cannot be accurately adjusted to bring that the aeration hole of the aeration membrane cannot be opened to the optimal state, the aeration hole is too small to cause low aeration efficiency, the aeration hole is too large to cause tearing of the aeration membrane and the like are solved, and therefore, the efficient sewage purification microporous aerator needs to be provided to solve the technical problems.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a pair of high-efficient sewage purification's micropore aerator, including front end housing, the check valve that admits air, aeration membrane locking device, aeration membrane, interior intake pipe, rear end cap: the aeration membrane is provided with an aeration membrane air outlet, and the inner air inlet pipe is provided with an air outlet and an inner air inlet pipe air outlet one-way valve.

Preferably, the front end cover is provided with an O-shaped sealing ring.

Preferably, the aeration membrane locking device is provided with a double-rivet hoop.

Preferably, the aeration membrane is provided with circular through hole air holes of the aeration membrane.

Preferably, the air outlet one-way valve of the inner air inlet pipe is a one-way flow stopping ball valve.

Preferably, the rear end cover is provided with a head lubrication hole O-shaped sealing ring.

Preferably, the front end cover and the rear end cover are provided with locking threads.

Preferably, the one-way flow stopping ball valve is provided with a flow stopping ball and a V-shaped flow stopping groove.

Preferably, the one-way check ball valves are sparsely distributed.

Compared with the prior art, the utility model provides a high-efficient sewage purification's micropore aerator has following beneficial effect:

(1) through the design, the air outlet one-way valve of the inner air inlet pipe is a one-way flow stopping ball valve, the flow stopping ball is larger than the V-shaped flow stopping groove, the distribution is sparse, the gap between the flow stopping ball and the aeration membrane is smaller, the V-shaped flow stopping groove is used, the aerator does not work, the flow stopping ball valve blocks the V-shaped flow stopping groove to prevent sewage from entering, the aeration membrane is separated from the inner air inlet pipe due to the fact that the flow stopping ball valve is higher, and the problem that the aeration membrane is tightly attached to the inner air inlet pipe to cause large jacking air pressure is avoided. Because the distribution is sparse, the one-way flow stopping ball valve is directly jacked open by small air pressure airflow, so that the airflow transmission efficiency is higher, and the aeration efficiency is improved. The front end cover and the rear end cover are designed to be of a threaded structure and an O-shaped ring sealing structure, so that sewage is prevented from entering the air inlet pipe. The aeration membrane and the inner air inlet pipe are tightly connected to form a double-rivet clamp, and the aeration membrane and the inner air inlet pipe are more tightly connected to prevent sewage from entering the air inlet pipe.

(2) Through the design aeration diaphragm be circular through-hole gas pocket, because the design of interior intake pipe one-way valve of giving vent to anger is one-way only to flow ball valve, the aeration diaphragm need not hug closely sealed with interior intake pipe and prevent that sewage from getting into, avoid the design of line type aeration hole because the aeration diaphragm aeration hole that the unable accurate adjustment of air pressure brought in the different water depth can't open to the optimum, aeration hole undersize then aeration inefficiency, the aeration diaphragm can be torn to the aeration hole too big then, the aeration diaphragm need often change scheduling problem, make the air current directly flow from the aeration hole through interior intake pipe one-way valve of giving vent to anger, make the aeration hole be in the optimum state of opening and shutting in real time, reduce energy consumption and the tearing replacement cost of aeration diaphragm.
