Description

A disc type microporous aerator

technical field

The utility model relates to an aerator, in particular to a disc-type microporous aerator.

Background technique

In the aerobic biological treatment unit in sewage treatment, it is necessary to supply oxygen to the sewage, usually air is blown in. The equipment widely used now is the microporous aerator. The existing microporous aerator directly supplies oxygen to the sewage. No protective measures are adopted. When the fan suddenly stops supplying air, sewage backflow is likely to occur due to the influence of negative pressure, causing damage to the equipment. In addition, the aeration air volume near the air intake pipe area is relatively large, while it is far away from the part of the aeration pipe. The air volume is small, consumes a lot of power, and the efficiency of aeration is low. The connection between the aerator and the air main pipe is easy to slide, and there are also problems that it is not easy to align with the air supply port.

Utility model content

The purpose of this utility model is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and provide a disc-type microporous aerator, which has a simple structure, can effectively prevent the phenomenon of backflow of sewage, and increases the contact area between air bubbles and water , improve the efficiency of aeration, can quickly dissolve oxygen, and greatly increase the amount of oxygen dissolved in water.

The purpose of the utility model is achieved through the following technical solutions: a disc-type microporous aerator, which is mainly composed of a hollow aerator body with openings at both ends, diaphragms and inlets respectively arranged on both ends of the aerator body The air device is composed of several micropores on the membrane, and a check valve is arranged between the aerator body and the air intake device.

A fixed end of the check valve is arranged inside the check valve, and a flexible movable piece of the check valve is installed on the fixed end of the check valve.

An O-ring sealing groove is arranged on the outer wall of the air intake device, and an O-ring is arranged in the O-ring sealing groove.

A membrane convex edge is provided on the periphery of the membrane, and the membrane is in contact with the aerator body through the membrane convex edge.

It also includes a diaphragm compression cover with one end arranged above the diaphragm and the other end fixed to the aerator body.

To sum up, the beneficial effects of the utility model are: the aerator has a simple structure, can effectively prevent the phenomenon of backflow of sewage, increases the contact area between air bubbles and water, improves the efficiency of aeration, can quickly dissolve oxygen, and is extremely Greatly increase the amount of dissolved oxygen in water.

Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

Example:

A disc type microporous aerator as shown in Fig. 1, Fig. 2, Fig. 3, and Fig. 4 is mainly composed of a hollow aerator body 3 with openings at both ends and two ends of the aerator body 3 respectively. A membrane 1 and an air intake device 6 are formed, the membrane 1 is provided with a number of micropores 102 , and a check valve 4 is provided between the aerator body 3 and the air intake device 6 . The check valve 4 can be installed to effectively reverse the flow of sewage. The diaphragm 1 is sealed and installed at one end of the aerator body 3 , and the diaphragm 1 is set in a slightly convex shape to increase the surface area of the diaphragm 1 . The air intake device 6 communicates with the interior of the aerator body 3 through the check valve 4 , and the air can pass through these components in sequence, and finally enter the sewage through the micropores 102 on the membrane 1 .

The check valve 4 is provided with a check valve fixed end 402 , and a check valve movable piece 401 that flexibly moves is installed on the check valve fixed end 402 . Under the action of the pressure, the rotation direction of the movable piece 401 of the check valve changes.

An O-ring sealing groove 5 is arranged on the outer wall of the air intake device 6 , and an O-ring is arranged in the O-ring sealing groove 5 . Capable of increasing the seal while strengthening the connection to the air main.

A membrane flange 101 is provided around the membrane 1 , and the membrane 1 is in contact with the aerator body 3 through the membrane flange 101 . The use of the membrane flange 101 makes the sealing effect better, and the membrane 1 will not be bonded to the aerator body 3 .

It also includes a diaphragm compression cover 2 with one end arranged above the diaphragm 1 and the other end fixed to the aerator body 3 . The diaphragm compression cover 2 can make the diaphragm 1 tightly fixed on the aerator body 3, and will not fall off due to pressure changes during use.

The working principle of the utility model: the air inlet device 6 of the disc microporous aerator is connected with the air main pipe, the air enters into the aerator through the air inlet device 6, and the air flow fixes the movable piece 401 of the check valve around the check valve The end 402 is pushed upward, and then the air enters the air storage chamber of the aerator, and the micropore 102 of the diaphragm 1 is raised and opened, and the diaphragm 1 evenly disperses the air into tiny bubbles and enters the water body, increasing the contact between the bubbles and the water The area can quickly dissolve oxygen, greatly increasing the amount of oxygen dissolved in water. When the fan suddenly stops supplying air, the pressure in the air pipe drops, the movable piece 401 of the check valve moves downward, and an airtight space is formed in the cavity of the aerator body, and the micropore 102 of the diaphragm 1 shrinks and closes, effectively preventing the phenomenon of sewage backflow.

By adopting the above method, the utility model can be better realized.
