Description
Technical field
The present invention relates to technical field of sewage, especially a kind of air floatation machine for municipal sewage treatment.
Background technology
Air floatation machine is a kind of using micro-bubble parcel suspension in water, is allowed to gradually float, realizes setting for separation of solid and liquid
It is standby.Air floatation machine is broadly divided into dissolved gas floatator and air flotation turbo, and dissolved gas floatator to water body by carrying out pressure air-dissolving, then
Depressurize again and realize that gas discharges to form microbubble.The microbubble small volume that this mode is formed, for the high treating effect of sewage,
But due to needing the auxiliary devices such as air compressor machine, circulating pump, cost is higher.Air flotation turbo rotates to be formed by the high speed of blade
Region of no pressure, the hollow axle that the air on liquid level passes through aerator input in water and go to fill a vacancy, and in blade high-speed rotation down cut
Bubble produces microbubble, and cost is low.The U of Chinese utility model patent CN 202482097 disclose a kind of air flotation turbo, pass through
Air admission hole is set on blade, improves cutting effect of the blade for gas.But this air floatation machine has compared dissolved gas floatator
It is relatively low for the utilization rate of air inlet, there are a large amount of gases to enter not broken and directly spread after water body.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of air floatation machine for municipal sewage treatment, prior art can solve the problem that
Deficiency, improve gas breaks up macro effect.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
A kind of air floatation machine for municipal sewage treatment, including casing, casing is interior to be provided with blade, casing by agitating shaft

The individual connecting tube with being connected on the outside of breather pipe；Blade bottom surface is provided with and groove, groove stitch between breather pipe and inner sleeve
The underface of gap, the width in gap is equal between groove and breather pipe and inner sleeve, and axial wheel, axle are fixed with agitating shaft bottom surface
The driving direction for flowing impeller is downward.
Preferably, the blade bottom surface and the spacing of breather pipe top surface are 5mm~8mm, the bottom of axial wheel is located at
In inner sleeve.
Preferably, being fixed with first baffle in the groove, first baffle and groove top surface are perpendicular, first baffle
Inner side is fixed with second baffle, and the angle of second baffle and first baffle is 35 °, is provided with cavity in first baffle, in cavity
Wing plate is staggeredly equipped with, spiral through hole is provided with second baffle, spiral through hole is connected with cavity, and spiral through hole side is set
There is the first through hole to be connected with second baffle surface.
Preferably, the cavity is connected with the top of groove by the second through hole, the second via top is provided with support,
If dried layer sheet metal is socketed with by gum cover on support.
Preferably, second via bottoms are connected with sealing-plug, sealing-plug and the second through hole by the first spring body
Selective grafting.
Preferably, the both sides of the groove are provided with silk screen layer, the height of silk screen layer is higher than the depth of groove.
Preferably, being provided with impeller by wheel shaft inside the silk screen layer, impeller surface is fixed with hairbrush.
It is using beneficial effect caused by above-mentioned technical proposal：The present invention changes the relative position of breather pipe and blade
Put, air-flow is flowed out from the bottom of blade, then rise to blade agitation position and broken up, this can improve gas and blade
Time of contact, improve " cutting " of the blade to gas and act on.Blade bottom recesses are used for receiving the gas that lower section rises
Collect and break up, the collision effect of bubble and blade can be effectively improved.Axial wheel provides a downward driving force, Ke Yiti
The circulating property of water body in high air floatation machine, so that the water body that increasing bubble is contained on water body upper strata can pass through blade again
Carry out " cutting ", so as to further improve the macro effect of bubble in water body.First baffle and second baffle can produce with water body
Raw mutually collision, further improve the macro effect of bubble in water body.Part water body enters cavity, Ran Houcong by the second through hole
Spiral through hole is flowed out, and this process can be not only shaken this part water body, improve the macro effect of bubble, even more important
, this flow tendency can be utilized, the water body flow speed in groove is improved, so as to improve the phase interaction of groove and water body
Use effect.Sheet metal is used for improving the collision macro effect to bubble in water body.But can be to groove after the second through hole is set
Internal " negative pressuren zone " impacts, in order to lower the influence for " negative pressuren zone ", by setting sealing-plug, when " negative pressuren zone " is pressed
When power raises, sealing-plug moves up, and its circulation area between the second through hole reduces, and reduces the inflow of water body, so as to keep " negative
The negative pressure state of nip ".Silk screen layer can carry out secondary agitation to the bubble in outflow groove water body and break up.But due to sewage
In contain substantial amounts of impurity particle, easily silk screen layer is resulted in blockage, in order to avoid this problem, the present invention is specially in silk screen layer
It is interior to be provided with impeller, flow through silk screen layer using water body and promote impeller rotation, so as to be cleaned with electric brush to hairbrush, avoid miscellaneous
The attachment of matter.
