Description
Technical field
The present invention relates to technical field of sewage treatment equipment, more particularly to a kind of hoisting type inverted umbrella-shaped surface aerator.
Background technology
, it is necessary to be oxygenated into sewage in sewage disposal process, so that beneficial bacterial growth is bred, reach decomposition
The purpose of dirty Organic substance in water, in the prior art, sewage is oxygenated frequently with surface aeration machine, surface aeration is in impeller
Strength progradation under, water is thrown away in water curtain shape from vane edge, forms water curtain, is wrapped up in into large quantity of air, and water body circulates up and down,
Liquid level, sewage large area and air contact are constantly updated, impeller rotation drives water body flow, forms negative pressuren zone, sucks air, empty
Oxygen in gas is dissolved in sewage rapidly, completes the oxygenation to sewage, but this aeration mode dissolved oxygen is only in water body superficial
Face, oxygenation capacity are restricted, and are oxygenated uneven.
Due to the anxiety of land resource, biological tank develops to deep channel type, and generally, liquid level is to biological tank bottom 4
More than rice, this requires aerator to take into account the effect of stirring lifting while aeration, prevents the dirt of zanjon bottom from settling.It is existing
There is only 1 meter submerged in water of the surface aeration machine in technology, the lifting effect to bottom of pond sewage is poor, the water velocity at biological tank bottom
It is relatively low, precipitation is easily produced, and aeration aerating effect is poor.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of hoisting type inverted umbrella-shaped surface aerator.
A kind of hoisting type inverted umbrella-shaped surface aerator proposed by the present invention, including mounting base, the impeller of falling umbrella and lifting member；
Mounting base is fixed in mounting foundation, and the quill shaft for the impeller of falling umbrella is driven by transmission device and hollow shaft lower end
Connection, hollow shaft with mounting base are connected through mounting base and by bearing, and hollow shaft upper end passes through intermeshing size
Gear and the first motor connection；
Lifting member is connected with the rotary shaft lower end being arranged in quill shaft and hollow shaft, and is arranged at below the impeller of falling umbrella,
Lifting member has the box like structure of opened upper end, and lifting member bottom is provided with some discharge orifices, and discharge orifice top is provided with and discharge orifice
The flowing water port lid of adaptation, flowing water port lid first end are rotatablely connected with lifting member, and the second end is connected with spring first end, spring second
End is connected with lifting member inner bottom surface；
Rotary shaft passes through the pilot hole of accessory mounting plate, and upper end is connected with supporting plate, and accessory mounting plate is installed by support
On mounting base, accessory mounting plate upper backup pad rotated down connects a cam, and cam is driven by the second motor.
First motor drives the impeller of falling umbrella to rotate by size gear train, strength progradation of the sewage in the impeller of falling umbrella
Under, thrown away from the edge for the impeller of falling umbrella, wrapping up in into above the average age for marriage air, makes the oxygen molecule in air soluble in water rapidly；
Lifting member is moved up and down in the presence of cam.Lifting member is from bottom to top in motion process, in rise rank
Section, water is downward to discharge orifice lid pressure, flowing water port lid is covered discharge orifice, because lifting member has the box-like knot of opened upper end
Structure, therefore, ascent stage can be by the less sewage liftings of the oxygen content of bottom to top；Lifting member is from top to bottom in motion process,
In the backhaul stage, water is upward to discharge orifice lid pressure, opens flowing water port lid, the water of rise graduated increasing will not be taken back into bottom
Portion.Due to the castering action of lifting member, make upward circulation in cesspool, renewal.
Sewage after elevated makes water body fully and air contact in the case where the stirring of the impeller of falling umbrella, plug-flow act on, so that
Fully it is oxygenated in water.
Preferably, lifting member medial surface is cylindrical, and diameter is more than the maximum gauge of the impeller of falling umbrella rotation, and depth is more than
The impeller height of falling umbrella direction full-size.Lifting member can be by bottom sewage lifting to the impeller location of falling umbrella, and the impeller of falling umbrella is being lifted
Part is in remote when stopping section, is directly stirred aeration to the bottom sewage lifted in lifting member, makes its aeration fully.
Preferably, tangential direction of the flowing water port lid low side to high-end projecting direction along the impeller of falling umbrella rotation is set, and is reduced
Loss of the lifting member in rise stage upward carrying capacity.
Preferably, discharge orifice is evenly arranged in lifting member inner bottom surface, lifting member is balanced in hydraulic pressure effect lower stress, prevents
Hydraulic pressure damages lifting member.
Preferably, the impeller of falling umbrella improves stirring action, increases the contact area of water body and air, so as to carry in umbrella
High oxygenation capacity.
Preferably, the impeller of falling umbrella is provided with floor, floor connection blade and quill shaft, and floor, which is provided with, to be used for the leaf of falling umbrella
The lifting hole(eyelet) sling is taken turns, is easy to sling or install the impeller of falling umbrella, floor also acts as the effect for improving the impeller intensity of falling umbrella.
A kind of hoisting type inverted umbrella-shaped surface aerator provided in the present invention, at the sewage in zanjon biological tank
During reason, because the castering action of impeller is limited, the lifting member that can be moved up and down is set in the lower section of inversed umbrella type impeller, by lifting member
Lifting member is set to be lifted to the sewage of biological tank bottom into box-like, according to bottom stressing conditions in lifting member motion process,
Discharge orifice is set in lifting member bottom, and coordinates the flowing water port lid of discharge orifice, flowing water port lid one end is rotatably installed in lifting member
Bottom, one end are connected with by spring with lifting member inner bottom part, hereby, it is achieved that it is dirty to carry out feeding bottom in lifting member ascent stage
Water, under gravity, toward flowing down, the water in biological tank forms the state of upward circulation for the water on top, depression of order under lifting member
Section will not also bring the sewage after lifting into bottom of pond, while coordinate under the stirring aeration effect for the impeller of falling umbrella, expose whole sewage
Gas is abundant.
The present invention is reasonable in design, simple in construction, and aeration is abundant, and oxygenation capacity is big, and intensity is high.
