{The air occurring apparatus in the water installed upper plate}

The present invention relates to an underwater air generator with an upper plate installed. More specifically, after the worker safely climbs on the upper plate with the underwater air generator installed integrally, the crane hook is inserted into the hook installed on the upper plate. Easy to lift and place it in a predetermined position, so that it can be safely maintained and replaced, and at the same time, an anti-vibration member made of a rubber material absorbing vibration of the motor installed in the underwater air generating device at the lower edge of the upper plate. By installing, it is possible to absorb the vibration generated in the motor and the blower to extend the life of the packing installed inside the flange and to easily detach the underwater air generator from the aeration tank.

Generally, various inorganic substances and microorganisms are contained in the aeration tanks of wastewater and wastewater purification facilities.If the wastewater and wastewater in the aeration tank is left, the wastewater and wastewater inside the aeration tank will stagnate and decay. It installs an air generating device and blows air into the wastewater at a predetermined pressure to actively activate microorganisms contained in the wastewater, thereby purifying the wastewater.

To this end, in the related art, an air generator installed with a blower that blows external air into the aeration tank while being rotated by a motor is installed outside the aeration tank, but this is caused by the external air blowing by the blower. , The wastewater was purified, but the noise generated by rotating the motor and the blower (about 110 ~ 120db) is very large, causing noise pollution, and the air generating device is installed on one side of the aeration tank to generate air There has been a problem that an installation space for installing the device must be provided.

In order to solve the above problems, as shown in FIG. 1, the underwater air generator 100 is installed on the inner bottom of the aeration tank 11 in which the waste water is filled, thereby supplying the outside air to the waste water. Although the noise generated by the motor of the underwater air generator 100 was attenuated in the water of the aeration tank 11 and the installation space was unnecessary, the underwater air generator 100 could not solve the problem. Since sludge 14 having a higher specific gravity than that contained in the wastewater and waste water is accumulated on the upper portion of the underwater air generator 100 because it is installed on the inner bottom of 11), underwater air is generated by the harmful components of the sludge. Since the device is easily corroded and its life is shortened, in order to prevent this, the aeration tank 11 is used for maintenance work such as injecting lubricant at least twice a year. After draining a considerable amount of waste and wastewater filled to a depth of about 4 to 5 m and making the aeration tank 11 empty, the worker should descend to the bottom of the aeration tank 11 to perform maintenance work. 11) It is virtually impossible to discharge a large amount of sewage and wastewater, which is filled in 11), so that the regular maintenance work of the underwater air generator cannot be performed, so even if the underwater air generator stops operating after a certain period of time, There was a problem that the maintenance and replacement work for the air generating device could not be performed normally, so that the wastewater inside the aeration tank could not be purified.
