Description
Technical field
The present invention relates to waste water control apparatus fields, and in particular to a kind of rotary disk aerator.
Background technique
With the rapid development of industry and urban construction cause, people's quality of life and horizontal raising, industrial wastewater and
Sanitary sewage increasingly increases.It pollutes, preserves the ecological environment in order to prevent, it is necessary to which this effluent part is handled.
In waste water control technique, using certain method and apparatus, forces that air is added into sewage, make sewage in pond
Oxygenation is contacted with air, and stirs liquid, accelerates transfer of the oxygen in air into liquid, prevents suspended substance in pond from sinking,
The contact for reinforcing organic matter and microorganism and dissolved oxygen in pond carries out compulsory oxygen aeration in oxygenolysis water to dirty Organic substance in water
Equipment is known as aerator.
Aeration is an important process link of sewage aerobic biochemical treatment system, its effect is filled into reactor
Oxygen, guarantee microbial biochemical acts on required dissolved oxygen, and keeps microorganism in reactor, substrate, dissolved oxygen, i.e. mud, water, gas
Three's is sufficiently mixed, and strong biochemical reaction condition is provided for microbial degradation organic matter.
Currently, the Chinese patent of Publication No. CN204874052U discloses a kind of frequency conversion type rotary disk aerator, it includes
Pond body, bearing block, the shaft being set in bearing block, the plate-spinning being evenly arranged in shaft, retarder, motor, frequency conversion tank and
Flowmeter has been evenly arranged convex block on the plate-spinning, which is equipped with pit on the vertical plane with plate-spinning, and the motor passes through
The rotation of retarder drive shaft, the sewage pipe that the pond body is equipped with sewage pump and is connected to sewage pump, the frequency conversion tank connection
Motor and sewage pump, flowmeter are set in sewage pipe.
Although this frequency conversion type rotary disk aerator hair improves the mixability of dirty water and air, increase molten in sewage
Oxygen concentration is solved, but since the water in cesspool is not unalterable, wastewater level and flow will receive the shadow of factors
It rings, when sewage water changes, the degree of mixing corresponding change of sewage and air can be dense to the dissolved oxygen in sewage to rotary disk aerator
Degree has an impact.
Summary of the invention
The object of the present invention is to provide a kind of rotary disk aerator, have can as SEA LEVEL VARIATION adjusts plate-spinning position,
So that the degree of mixing of sewage and air is in preferred values always, reduces the advantages of water level has an impact dissolved oxygen concentration in sewage.
Above-mentioned technical purpose of the invention technical scheme is that：
A kind of rotary disk aerator, motor reducer including shelves, in shelves and passes through motor reducer and drives
Shaft and plate-spinning, the setter plate that shelves include frame and are vertically slidably connected on frame, motor reducer it is solid

Saturating driving plate is simultaneously threadedly coupled therewith, when driving lead screw rotation, is able to drive driving plate and is slid up and down, to change setter plate
Whole height.
Further setting：Driving mechanism includes the drive rack being fixed in driving plate perpendicular to horizontal plane, is turned in frame
Dynamic to be connected with driving gear, driving gear is engaged with drive rack.
By using above-mentioned technical proposal, when needing to adjust driving plate and setter plate whole height, operator can lead to
Drive driving gear rotation is crossed to adjust the height of drive rack, to achieve the purpose that change placement Board position.
Further setting：Driving mechanism further includes rotating electric machine, and active worm screw is fixed on the output shaft of rotating electric machine, is driven
Moving gear is equipped with universal driving shaft, is fixed on universal driving shaft and driving gear worm driver gear disposed in parallel, worm driver gear and active
Worm screw intermeshing.
By using above-mentioned technical proposal, rotating electric machine drives the rotation of active worm screw, linkage driving gear and universal driving shaft, with
And it is fixed on the driving gear rotation on universal driving shaft, achieve the purpose that drive drive rack.Since worm and gear has self-locking performance,
The height of drive rack can be limited by worm and gear.
Further setting：Plate-spinning recess setting, side surrounding central axes are equipped with several baffles, relative to gear on baffle
Plate inclination offers several stomatas.
More sprays are able to drive by baffle in plate-spinning and waste water by using above-mentioned technical proposal, and
The setting of stomata can allow more air-flows to pass through, to improve the dissolved oxygen concentration in afternoon nap.
In conclusion the invention has the advantages that：
The height that can change the height of plate-spinning according to the variation of water level and contact with the water surface, makes connecing between plate-spinning and sewage
Touching amount is in preferred values, guarantees that sewage degree of mixing with air is suitable, to reduce what water level generated dissolved oxygen concentration in sewage
It influences, improves the aeration effect of sewage.
