Abstract

The utility model discloses a micropore aerator, which comprises an aerator body (3) and a diaphragm (1) of which the periphery is hermetically connected with the aerator body (3). A gas storage cavity (4) is formed between the diaphragm (1) and the aerator body (3); the diaphragm (1) is provided with micropores (7) penetrating through the upper end face and the lower end face of the diaphragm (1) and communicating with the gas storage cavity (4); and the aerator body (3) is provided with an admission pipe (5) communicating with the gas storage cavity (4). As the structure is adopted, the integral structure of the micropore aerator is simple, and the aeration efficiency is improved. Moreover, the phenomenon that sewage flows back can be prevented from happening, and thereby, the phenomenon that the micropore aerator and an air pipe are damaged because the sewage inflows can be avoided.

Description

A kind of micro-hole aerator

Technical field

The utility model relates to a kind of aerating apparatus, specifically is a kind of micro-hole aerator.

Background technology

Aerobe processing unit in sewage disposal need generally adopt the mode that blasts air to sewage to the sewage oxygen supply to the sewage oxygen supply now, and blasts the aerator of the most frequently used equipment of air for being connected with blast main to sewage.When the existing blower fan of aerator in blast main stops air feed, because the influence of negative pressure in the aerator, occur sewage easily and flow backward to the interior phenomenon of aerator, and the sewage that flow in the aerator very easily enters in the blast main, this just makes aerator and blast main fragile, thus the work-ing life of having reduced aerator and blast main.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of micro-hole aerator that can stop sewage to flow backwards when the blower fan of blast main stops air feed being provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of micro-hole aerator, comprise the aerator body, and diaphragm peripheral and that the aerator body is tightly connected, constitute air storing cavity between diaphragm and the aerator body, diaphragm is provided with the micropore that runs through its upper and lower end face and connect air storing cavity, and described aerator body is provided with the inlet pipe of connecting air storing cavity.Wherein, the quantity of micropore is set to a plurality of, and all micropores are evenly distributed on the diaphragm.

Be provided with check device in the described air storing cavity, described check device comprises rubber non-return body, and the non-return lower end body of connecting air-flow between air storing cavity and the inlet pipe, described rubber non-return body upper end is connected with diaphragm seal, the upper end sealing of its lower end and non-return lower end body touches, described non-return lower end body and inlet pipe size coupling, and its lower end is connected with inlet pipe.

The upper end of described non-return lower end body constitutes funnel-form, and the lower end of described rubber non-return body constitutes the coniform of the upper end size bucket-shaped with non-return lower end body drain, form fit.

Described non-return lower end body is the pipe connecting of hollow cylindrical.

The outer wall of described inlet pipe is provided with connecting thread, and the utility model is connected with blast main by this connecting thread.

Principle of work of the present utility model: inlet pipe of the present utility model is connected with blast main by the connecting thread that is arranged on its outer wall, when the blower fan of blast main is worked, blast main is to the utility model input air, air enters in the body of non-return lower end by inlet pipe, the intravital gas pressure in non-return lower end is in rubber non-return body, and make between rubber non-return body and the non-return lower end body no longer that sealing touches, air then enters in the air storing cavity, along with the air in the input air storing cavity increases, acting on diaphragm-operated air pressure increases, thereby make diaphragm epirelief and drive as moving on the glue non-return body, the micropore on the diaphragm is opened, and air enters in the sewage by micropore; When the blower fan of blast main quits work, blast main stops to the utility model input air, discharging along with air in the air storing cavity, the intravital air pressure of air storing cavity and non-return lower end all reduces, under diaphragm-operated drives, rubber non-return body moves downward, and rubber non-return body and non-return lower end body recover sealing and touch.

The utility model compared with prior art has the following advantages and beneficial effect: (1) diaphragm of the present utility model is provided with micropore, the utility model is not when sewage blasts air, the diaphragm-operated micropore shrinks closes, thereby can effectively stop sewage to flow backward in the utility model, avoid sewage to enter in aerator and the blast main; When the utility model when sewage blasts air, the air exported in air storing cavity enters into sewage through constituting small bubble behind the micropore, bubble has increased the air of discharging and the contact area of sewage, thereby can improve aeration efficient.

(2) the utility model is provided with rubber non-return body and non-return lower end body, and when not having airiness in the utility model, rubber non-return body and the sealing of non-return lower end body touch, thereby can further stop in the blast main that sewage enters with the utility model is connected.
