本考案は、ビル排水槽等汚水槽内の汚水を攪拌
し、空気を吹込む曝気装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an aeration device that agitates wastewater in a sewage tank such as a building drainage tank and blows air into the wastewater.

Conventionally, an aeration device disclosed in Japanese Utility Model Publication No. 58-26079 has been known. This known aeration device has a sewage inlet in the lower part of the device. Therefore, sewage flows into the tank from the bottom and is discharged into the tank for aeration.

This aeration equipment could not treat the scum on the surface of the sewage as it remained suspended. The inventor installed the inlet of the draft tube at a position below the sewage water surface to allow the scum to flow in and crush it, but in a sewage tank where the water level fluctuates rapidly, the inlet was located far from the water surface. However, there were cases where sufficient scum could not be introduced and crushed.

The present invention is an aeration device installed at the bottom of the water,
In the aeration device in which the stirring blade is covered with a draft tube, the inlet side of the draft tube is configured to be expandable and retractable, and is supported by a float that maintains the inlet at a certain position below the water surface. This keeps the inlet at a constant position below the water surface regardless of changes in the water level, allowing sufficient flow of scum above the water surface.

す。 In the figure, 1 is a sewage tank such as a building drainage tank, and an aeration device 3 is installed at a desired position on the bottom 2 of this sewage tank 1. The aeration device 3 includes a prime mover 4 such as a submersible motor or a hydraulic motor, a stirring blade 5, a draft tube 6, an air blowing pipe 7, and a float 8.
The prime mover 4 is fixed to the bottom of the tank, and a draft tube 6 bent into an L-shape is integrally provided at the bottom of the tank. Further, the inlet 6a of the draft tube has a flared shape. A stirring blade 5 driven by the prime mover 4 and an air blowing pipe 7 are provided in this draft tube. The upper end of this air blowing pipe 7 is a pipe having a diameter such that it is always open to the atmosphere even if the water level fluctuates, and the required amount of air is blown into the pipe. The blade 5 is positioned in a negative pressure zone generated in the liquid by rotation of the blade 5.
又、流入口６ａは水面下の所要位置に位置させ
るため、流入口６ａの円周上にフロート９を設け
る。実施例でフロート９を３個設けているが、必
要に応じて何個でも設けることができる。 Further, in order to locate the inlet 6a at a desired position below the water surface, a float 9 is provided on the circumference of the inlet 6a. Although three floats 9 are provided in the embodiment, any number of floats 9 may be provided as needed.
次に、フロートに設けた流入口６ａに追随し
て、伸縮自在の伸縮管６ｃを流入管６ａとドラフ
トチユーブ管に設ける。 Next, following the inlet 6a provided in the float, a telescopic tube 6c is provided in the inlet tube 6a and the draft tube tube.
この伸縮管６ｃは第１図にみられる蛇腹式のフ
レキシブル管または第３図にみられるスライドに
より伸縮する管を使用することが可能である。 As the telescopic tube 6c, it is possible to use a bellows-type flexible tube as shown in FIG. 1 or a slideable tube as shown in FIG. 3.
而して上述のように構成する曝気装置に於て原
動機４を駆動すると攪拌羽根５が回動し、槽内の
汚水を攪拌する。これにより、この羽根先端部分
の液中に負圧が発生し、この負圧にて大気中から
空気が、液中に吹き込まれる。 When the prime mover 4 is driven in the aeration system constructed as described above, the stirring blades 5 rotate to stir the wastewater in the tank. As a result, negative pressure is generated in the liquid at the tip of the blade, and air is blown into the liquid from the atmosphere at this negative pressure.
そして、ドラフトチユーブ内の攪拌流は空気と
混合され、ドラフトチユーブ前方向へ押し出され
る。 Then, the stirring flow inside the draft tube is mixed with air and pushed out toward the front of the draft tube.

る。 Next, the scum floating on the water surface is sucked into the draft tube from the inlet 6a, and the stirring blade 5
crushed by. Even if the water level fluctuates, the float 9 follows and moves the inlet 6a and the telescopic pipe 6c, so the distance between the water surface and the inlet is always constant.
従つて、常に十分な量の水面上のスカム９を流
入口より吸い込み攪拌羽根で破砕することが可能
である。 Therefore, it is possible to always suck in a sufficient amount of scum 9 on the water surface from the inlet and crush it with the stirring blade.
又、この曝気装置により汚水中の有機物を好気
性分解して浄化し、悪臭発生を防止するものとな
る。 In addition, this aeration device aerobically decomposes and purifies organic matter in wastewater, thereby preventing the generation of bad odors.

According to the present invention, a stirring blade is rotated in a draft tube installed at the bottom of the tank to blow in air from the atmosphere, and the inlet of the draft tube can be moved up and down by a float in response to water level fluctuations. This has the effect of always sucking in a sufficient amount of scum on the water surface and crushing it with stirring blades.
