Description
Technical field
The utility model belongs to sewage aerobic processing technology field more particularly to a kind of spiral lifting aerator.
Background technique
Currently, the prior art commonly used in the trade is such that
Generally used aerator in various water treatment fields at present, so-called aeration refer to by gas force to
The process dispersed in liquid, the purpose is to obtain enough dissolved oxygen contents.In trade effluents such as weaving, printing and dyeing, papermaking, chemical industry and
During the biochemical processing process of city domestic sewage, need in dirty oxygen in water, and aerator be realize aeration, provide it is molten
Solve the necessary equipment of oxygen.
Currently, aerator is many kinds of both at home and abroad, but it can substantially be divided into micro-hole aerator and mesoporous aerator, it is micro-
The features such as there are diaphragm agings for hole aerator, block, and fouling, resistance are big, and service life is short, existing mesoporous aerator is all to produce
5 millimeters raw or more air pocket.And bubble is bigger, and than table, product is smaller, and gas effciency is lower, aeration cost is higher.Market
That there are service lifes is short for existing aerator, and energy band water is not installed, and the rate of transform of oxygen is low.
In conclusion problem of the existing technology is:
Existing aerator is easy blocking fouling, and service life is short, and energy band water is not installed, and the rate of transform of oxygen is low.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of spiral lifting aerator.
The utility model is realized in this way a kind of spiral lifting aerator is provided with shell；
Shell left end is provided with inlet flange, and the tracheae of inlet flange right end and clamping inside the housing welds, and tracheae is right
End bolt has nozzle；
It is welded with pod on the outside of inlet flange, interior of shell left end is welded with multilayer inverted triangle cutting plate, and inverted triangle is all
It is designed with card slot, mixing wastewater with air liquid is allowed to generate cutting and toll bar effect, enclosure interior centre is welded with spiral plate, shell in two sides up and down
Internal portion right end is welded with flow distribution plate, is negative pressure cavity on the right side of flow distribution plate.
Further, nozzle is single direction rotation nozzle clockwise, can be rotated clockwise under the promotion of pipe air-flow.
In conclusion the advantages of the utility model and good effect are as follows:
The utility model is in a kind of stationary state, drag losses very little, than table exposure, jet stream, rubber, ceramics in operation
Equal aerators product saves the electricity charge 30%, and the rate of transform of oxygen is high, and normal use 10 years or more.It can exist to sewage treatment aeration tank
Band water is installed in the case where not stopping production, and since connection type is reasonable, accurately this kind of aerator can be installed in place, and is not necessarily to bottom
It is fixed, it is vertically-mounted on pond top, because not needing to drain, fast and easy installation and maintenance.Aerator venthole aperture is big,
It never blocks, strong pumping pool bottom sludge accumulate sludge will not, and gas-vapor mix is ideal in aerator, generates microbubble and stops
Time is long, and oxygen transfer rate is high.
The utility model aerator has generation bubble small, gas-vapor mix is filled according to jet stream, spiral, Karman vortex street principle
Point, the microbubble the advantages that residence time is long in water, the resistance for solving original aerator is big, and energy band water is not installed, and oxygen utilizes
The problems such as rate is low, sludge accumulation, service life is short.The popularization of the utility model aerator is practical inherently above energy-efficient
It plays a role, uses, installation, operating cost reduces, and has important practical value.
Detailed description of the invention
Fig. 1 is spiral lifting aerator structural schematic diagram provided by the embodiment of the utility model；
In figure: 1, inlet flange；2, pod；3, inverted triangle cutting plate；4, spiral plate；5, tracheae；6, nozzle；7, it shunts
Plate；8, negative pressure cavity.
Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
As shown in Figure 1, spiral lifting aerator provided by the embodiment of the utility model includes: inlet flange 1, pod
2, inverted triangle cutting plate 3, spiral plate 4, tracheae 5, nozzle 6, flow distribution plate 7, negative pressure cavity 8.
Shell left end is provided with inlet flange 1, and the tracheae 5 of 1 right end of inlet flange and clamping inside the housing welds, tracheae
5 right ends bolt has nozzle 6；
It is welded with pod 2 on the outside of inlet flange 1, interior of shell left end is welded with multilayer inverted triangle cutting plate 3, in shell
Two sides are welded with spiral plate 4 up and down among portion, and it is negative pressure cavity 8 on the right side of flow distribution plate 7 that enclosure interior right end, which is welded with flow distribution plate 7,.
As a preferred embodiment, nozzle 6 is single direction rotation nozzle clockwise.
The utility model uses propeller and jet stream, Karman vortex street principle, and gas is suitable by 4 of 5 lower end of middle gas tube
Conterclockwise nozzle 6 sprays, and gas moment under the action of spiral plate 4 along gas chamber inner wall is rotated clockwise rising, together
When keep aerator internal mix liquid density low, negative pressure is formed in aerator internal negative pressure chamber 8, thus by external muddy water mixed solution
It sucks the bottom of aerator in the shape of a spiral and the air mixing led to, inverted triangle cutting plate 3 is passed through when by aerator top
The multiple impacts cutting and vortex street effect of upper inverted triangle generate many micro-bubbles, then pass through the pod 2 of aerator topmost
The area of rising is expanded, to improve the rate of transform of oxygen.Since aerator bottom is to the swabbing action of sludge, dirt is avoided
Accumulation of the mud in bottom of pond.Muddy water mixed solution is sprayed from top, is taken to after the water surface of pond by bubble and is declined naturally, is formed in up and down and is followed
After ring, so the service area of every aerator increases, while achieving the effect that muddy water mixed aeration.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
