Specific embodiment
Following embodiment only exists in illustrative purpose, limits the scope of the invention without being intended to.
Embodiment
Referring to Fig.1-2, a kind of Industrial Wastewater Treatment air-floating apparatus, including supersonic generator 1 and cylinder 2, cylinder 2
Upper end be higher than the liquid level of cesspool, supersonic generator 1 is arranged in the bottom of cesspool, the bottom sealing of cylinder 2 and its side
Wall offers multiple side openings 3, and gluing has side waterproof ventilated membrane 5 in each side opening 3, and the two sides of waterproof ventilated membrane 5 are bonded
There is a hard web plate 4, each hard web plate 4 is fixedly connected with cylinder 2, and the top of supersonic generator 1 is arranged in cylinder 2, firmly
The screen size of web plate 4 is 20 mesh~16 mesh, and under this size, the bubble diameter of single evolution is about 1mm, and lesser bubble is convenient for
The devices such as later period soft web plate 6 are ground into smaller micro bubbles, and the sieve pore of a hard web plate 4 in 5 two sides of waterproof ventilated membrane is wrong
Position is arranged, and the pressurizing device of controllable 2 air pressure inside of cylinder is provided with above cylinder 2；
Pressurizing device includes sealing the counterweight piston 8 being slidably connected with 2 inner wall of cylinder, to keep stable gas pressure in cylinder 2
Purpose.
At least gluing has one layer of soft web plate 6 in each side opening 3, and the screen size of soft web plate 6 is 20 mesh~16 mesh, soft net
Plate 6 is made using nylon wire, and tensioning is glued in side opening 3；Cylinder 2 is provided with guide plate close to the side of cesspool water inlet end
7, guide plate 7 is obliquely installed at the current deflecting supersonic generator 1 will newly flow into.
In the present invention, pressurizing device can increase the air pressure in cylinder 2, so that the pressure of 5 two sides of waterproof ventilated membrane is substantially
It is equal, i.e., without under external force when, the gas in cylinder 2 is in the critical point across waterproof ventilated membrane 5；
Supersonic generator 1, which issues, will drive the water body high-frequency vibration of surrounding after ultrasonic wave, waterproof ventilated membrane 5 also certainty with
Water body generates high-frequency vibration together, and the part moment is had in vibration processes in the shape to concave at the sieve pore of hard web plate 4
State, so the speed that waterproof ventilated membrane 5 is recessed inwardly is exceedingly fast, necessarily leads to corresponding position since vibration frequency is very big at this time
Air pressure increases to the hydraulic pressure more than 5 other side of waterproof ventilated membrane suddenly, so that partial air is worn under the action of pressure difference
Waterproof ventilated membrane 5 is crossed, air, which will form bubble after passing through hard web plate 4, to be continued to move out；
Soft web plate 6 at side opening 3 can also be generated high-frequency vibration by ultrasonic wave action, and bubble is when by soft web plate 6, high frequency
Bubble can be smashed into the smaller micro bubbles of diameter by the soft web plate 6 of vibration, and micro bubbles will be with sewage after entering cesspool
In impurity contact and adhere to mutually so that the impurity being suspended in cesspool can quickly swim in topmost surface,
The impurity for swimming in the water surface need to only be removed the processing that can be completed to suspended matter in sewage by the later period.
When the water inlet end inflow of cesspool is suspended with the sewage of impurity, it can emit under the action of guide plate 7 to ultrasonic wave
Device 1 flows about, supersonic generator 1 generate drive suspend impurity fast vibration, thus make impurity quickly disintegrates formed compared with
Small structure, after disintegration to crush impurity smaller with the combined density after micro bubbles attachment, so can be faster to floating up to
The water surface.
Meanwhile micro- gas core cavitation bubble in liquid vibrated under the action of ultrasonic wave will form cavitation phenomenon and generate number with
The micro-bubble of ten thousand meters, i.e. cavitation bubble.The negative pressuren zone growth that these cavitation bubbles are formed in ultrasonic wave longitudinal propagation, and in zone of positive pressure
Rapid closing, to be compressed and be stretched under alternately positive and negative pressure.Collapse is compressed up in a flash in cavitation bubble, meeting
Huge instantaneous pressure is generated, generally to megapascal up to a hundred, this huge instantaneous pressure can will be not easy to disintegrate up to tens megapascal
Impurity crush, further achieve the purpose that make impurities in water to crush；
It is worth noting that supersonic generator 1 discharges the cavitation bubble of ultrasonic wave generation when bursting in water body, also can
The micro bubbles escaped in cylinder 2 are blown into the bubble of smaller micron level, thus make these bubbles be easier to in water
Impurity phase combines, and the device of the invention handles suspended matter in sewage more thorough.
Counterweight piston 8 in the present invention can seal in cylinder 2 to be slided up and down, and the gas in cylinder 2 is through side opening 3 to escaping
The air pressure in cylinder 2 can be made to reduce out, counterweight piston 8 can be moved downward in the presence of its gravity to keep in cylinder 2
Stable gas pressure is in preset range；
In addition to selecting counterweight piston 8 to 2 persistent pressure of cylinder, the devices such as force (forcing) pump also can be selected and pump gas into cylinder 2, with
Realize the purpose for keeping stable gas pressure in cylinder 2.
Although supersonic generator 1, cylinder 2, side opening 3, hard web plate 4, waterproof ventilated membrane 5, soft is used more herein
The terms such as web plate 6, guide plate 7, counterweight piston 8, but it does not exclude the possibility of using other terms.Only using these terms
It is to be more convenient to describe and explain essence of the invention；Being construed as any additional limitation is all and this hair
What bright spirit was disagreed.
