Description

Tubular Steel Mesh Diaphragm Aerator Head

technical field

The utility model relates to a tubular steel mesh microporous aeration head.

Background technique

The aerator head is the head-end part of the aerator. It is generally combined with the air supply pipeline connected behind to form a complete aerator. The aerator head is generally placed in the sewage tank, and the compressed air passes through the air supply pipeline through the aerator head. The micropores are divided into tiny bubbles and dispersed in the water to achieve the purpose of dissolving oxygen.

The traditional diaphragm aeration head is generally composed of an air distribution pipe and a microporous rubber membrane on the jacket: the air distribution pipe is a plastic distribution pipe, and the holes on it are not microporous holes, but between Φ4 and Φ12. The large holes play the role of evenly distributing the air; the air distribution pipe is covered with a rubber diaphragm with micropores. There are many micropores evenly distributed on the diaphragm. When there is no air flowing through, the micropores on the diaphragm are Closed, the pores in the diaphragm open when air under pressure passes through. Its defects are: 1. If the membrane expands too much, it is easy to tear; 2. When inflated, the membrane expands and causes the air outlet holes to be too large, resulting in poor aeration effect and affecting the water quality.

Contents of the invention

The purpose of the utility model is to provide a tear-proof tubular steel mesh microporous aeration head.

In order to achieve the above purpose, the utility model adopts the following design scheme: a tubular steel mesh microporous aeration head, including an air distribution pipe and an outer sleeve-shaped diaphragm, and a steel mesh pipe is set outside the tubular diaphragm.

The steel mesh pipe is a 5-20 mesh stainless steel wire mesh; the diaphragm is made of EPDM (? Chinese name) material diaphragm.

Tubular steel mesh microporous aeration head is a new type of microporous aeration equipment in the process of industrial sewage and municipal sewage treatment.

The utility model has the advantages of being beneficial to the control of the bubble diameter, not easy to tear, long in service life and high in oxygen utilization rate.

Detailed ways

As shown in Figure 1, the tubular steel mesh microporous aeration head of the utility model includes an air distribution pipe 3 and an outer sleeve-shaped diaphragm 2, and the front end of the air distribution pipe is covered with a front end cover 5. Its improvement lies in: it is to install a stainless steel wire mesh outside the aerator head of the previous tubular diaphragm aerator (steel mesh pipe 1, 5-20 mesh is better); the diaphragm is made of EPDM ) material diaphragm, EPDM (ethylene propylene diene yuan) material has the performance of elastic expansion, and silicon rubber can also be used as the diaphragm. In addition, clips 4 are provided at the front and rear ends of the air distribution pipe.

The distance between the diaphragm and the steel mesh of the utility model has a certain reasonable space (the distance between the diaphragm and the steel mesh is preferably 1-8mm), which protects the diaphragm and ensures that the passage of the airflow is not hindered when the diaphragm expands.

By adopting the technical solution of the utility model, the aeration head is in direct contact with the lower water body, so the bottom resistance is low and the lifting capacity is strong.

The steel mesh of the tubular steel mesh microporous aeration head of the utility model limits the excessive expansion of the diaphragm, so that the diaphragm of the traditional microporous aeration head is not easy to be damaged, and the aperture is smaller, thus improving the service life of the aeration head and Oxygen utilization.
