Description
Technical field
This utility model belongs to sewage treatment area, particularly relates to a kind of hydraulic agitation device.
Background technology
At sewage treatment area, so that sewage can fully react in reaction tank, it is to avoid sewage reacts not
Fully, it usually needs in reaction tank, add water-locator and agitating device be stirred, so that reaction tank
Interior sewage can mix, be evenly distributed.But generally reaction tank is relatively big, agitating device structure is complicated, installs
Difficulty is relatively big, relatively costly.
Utility model content
The purpose of this utility model is to overcome prior art to there is agitating device structure complexity, and cost is high
Defect, it is provided that a kind of hydraulic agitation device.
This utility model solves its technical problem and be the technical scheme is that a kind of hydraulic mixing dress
Put, including shell and the inner cavity being arranged in described shell, formed between described shell and inner cavity
Negative pressure cavity, described shell is provided with some in contraction-like first jet, described first jet and institute
State negative pressure cavity connection, described inner cavity is provided with corresponding with some described first jet some
In contraction-like second nozzle, described first jet is stretched in the front end of described second nozzle, and described second
Nozzle connects with described inner cavity inner chamber body；It is internal and the external world to be provided with connection on described inner cavity
Water inlet pipe, described shell is provided with connection negative pressure cavity and extraneous suction hose.
Further, for ease of hydraulic agitation device installation in reaction tank, also include support, institute
State support and be arranged on outer casing bottom.
Further, being provided with water sucking mouth bottom described suction hose, described water sucking mouth is horn-like.
Can expand water suction area in trumpet-shaped water sucking mouth, and utilize the inwall of bell-mouthed inclination can
Effectively the mud entering water sucking mouth is blocked, and sink under mud self gravitation, reduce mud and enter
In hydraulic agitation device, and the problems such as the blocking caused.
Further, described first jet centrage is positioned at horizontal direction.First jet level can
The current horizontal throw that nozzle is ejected is maximum, thus increases stirring area.
Further, also including return duct, described return duct is arranged on the edge of reaction tank, on it
Being provided with some refluxing openings, described return duct is connected with described water inlet pipe by circulating pump.Due to instead
Answer pond inside edge that stirring dead angle easily occurs, and return duct and refluxing opening are set in edge, following
Make sewage backflow about in hydraulic agitation device under ring pumping action, it is to avoid the existence at dead angle,
Make sewage reaction fully.
As preferably, when reaction tank is square, described refluxing opening is arranged on returning of reaction tank corner
In flow tube.Owing to square reaction tank corner can form stirring dead angle, sewage can not get stirring reaction
Insufficient, and be back in hydraulic agitator effectively to be sucked by waste water at dead angle by refluxing opening,
And be distributed in reaction tank, it is to avoid the existence at dead angle.
Beneficial effect: utilize the mating reaction of the first jet in contraction-like and second nozzle in the application
Negative pressure is produced, so that produce negative-pressure sucking in suction hose so that in reaction tank in making negative pressure cavity
Sewage be inhaled into, eject after mixing with newly entering sewage or circulating sewage, and due to
One nozzle is contraction-like, and therefore, expulsion pressure is big, and range is farther, and stirring, mixed effect are more preferable.

Detailed description of the invention
Embodiment 1
As shown in Figures 1 to 3, a kind of hydraulic agitation device, including shell 1, it is arranged on described shell 1
In inner cavity 2 and be arranged on the support 6 bottom shell 1, between described shell 1 and inner cavity 2
Form negative pressure cavity 3, described shell 1 is provided with some in contraction-like first jet 11, described the
One nozzle 11 connects with described negative pressure cavity 3, and described first jet 11 centrage is positioned at horizontal direction,
It is provided with corresponding with some described first jet 11 some in contraction-like on described inner cavity 2
Second nozzle 21, the front end of described second nozzle 21 stretches into described first jet 11, described second
Nozzle 21 connects with described inner cavity 2 inner chamber body；It is provided with on described inner cavity 2 and connects inside it
With extraneous water inlet pipe 4, described shell 1 is provided with connection negative pressure cavity 3 and extraneous suction hose
5, it is provided with water sucking mouth 51 bottom described suction hose 5, described water sucking mouth 51 is in horn-like.
As shown in Figure 4, also include that return duct 9, described return duct 9 are arranged on the edge of reaction tank 7
Place, is provided with some refluxing openings 91, described return duct 9 by circulating pump 8 with described enter
Water pipe 4 connects.When reaction tank 7 is square, described refluxing opening 91 is arranged on reaction tank 7 turning
On the return duct 9 at place.
Operation principle is as follows: start circulating pump 8, by the sewage transport of reaction tank 7 inside edge to entering
Water pipe 4, sewage is entered first jet 11 by the cavity of inner cavity 2 through second nozzle 21, and
One nozzle 11 and second nozzle 21 junction form negative pressure, form negative pressure, water sucking mouth in negative pressure cavity 3
51 under suction function the sewage in sucting reaction pond 7, and first jet 11 with by second nozzle
The sewage mixing that 21 enter, is finally sprayed by first jet 11, owing to first jet 11 is in contraction
Shape, therefore jet length is remote, and stirring scope is big.
Pump can certainly be utilized directly to be connected with source of sewage by water inlet pipe 4, thus reach new sewage with
The effect of sewage mixing in reaction tank 7 so that i.e. produce stirring action during entering sewage, meanwhile,
New sewage mixes the COD concentration that can reduce new sewage with sewage in reaction tank 7, reduces reaction tank
The load of strain and impact in 7.
Should be appreciated that specific embodiment described above is only used for explaining this utility model, and need not
In limiting this utility model.The obvious change extended out by spirit of the present utility model or change
Move among still in protection domain of the present utility model.
