Detailed description of the invention
Accompanying drawing being merely cited for property explanation, it is impossible to be interpreted as the restriction to this patent；In order to the present embodiment is more preferably described, attached
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
In accompanying drawing, some known features and explanation thereof may be omitted and be will be understood by.
In description of the present utility model, it should be noted that unless otherwise clearly defined and limited, term " peace
Dress ", " connection " should be interpreted broadly, for example, it may be fixing connection, it is also possible to be to removably connect, or be integrally connected；Can
To be mechanical connection, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be to be indirectly connected with by intermediary, permissible
Say the connection of two element internals.For the ordinary skill in the art, can understand that above-mentioned term exists with concrete condition
Concrete meaning of the present utility model.With embodiment, the technical solution of the utility model is done further below in conjunction with the accompanying drawings
Bright.
As it is shown in figure 1, a kind of multistage aeration generator, including generator body 1, it is arranged on the pressure on generator body
Supervisory device 2 and Venturi nozzle 3, also include: capillary vessel 4 and concentric tube 5, and capillary vessel one end is with Venturi nozzle even
Connecing, the other end is connected with concentric tube, and this device is novel in design, the combination of Venturi nozzle and concentric tube, using the teaching of the invention it is possible to provide continue and
The trickleest stable foam, can make output variation for the change of input operating parameters simultaneously immediately；With regulation and control

One end is connected with nozzle back outlet device, and Venturi nozzle uses rational geometric curved surfaces parameter designing to form, and can be formed big
The water circulation of flow, and there is the spray-hole preventing blocking.Concentric tube includes inner tubular member, idiosome and outer tubular structure
Part, idiosome one end is connected with inner tubular member, and the other end is connected with outer tubular member, by during the sintering of preparation process one
Individual pipe method of radial contraction on another pipe prepares tubular body so that object has the performance in radial variations, inner tube
Being additionally provided with multilayer concentric layer on shape component, pressure supervisory device includes pressure transducer and pressure-display device, pressure transducer
Electrically connect with pressure-display device, the pressure data that in pressure transducer energy induction installation, fluid is formed, and be fed back to pressure
In power display device, reminding operator to note, concentric tube is provided with flow-monitoring device.This device can provide and continue and stable
The trickleest foam.The most most important achievement is, can make output variation immediately for the change of input operating parameters；
With regulation and control air feed and pump speed, to produce suitable foam density and size for subsequent treatment, when air is with useless
Water mixes along cross section in pump, by gasification to time saturated, before entrance Venturi nozzle combines with concentric tube, now according to Henry
Under law, molten gas can be released under particular fluid pressure and form " gas phase aqueous phase balance " at this point.But, most of undissolved air
It is stirred with the form of relatively large foams mix, the pressure difference between base what Venturi nozzle entrance and exit, is dissolved in
The air of liquid is pressed under Henry law, and first another typical material " condenses " to form gas bubble from full gasification.In this stage,
It is extracted another typical material, and blends with (air after undissolved and agitation is formed) macrofoam, prepared both stable
The trickleest foam.
In figure, position relationship being merely cited for property explanation is described, it is impossible to be interpreted as the restriction to this patent；Obviously, this reality
It is only for clearly demonstrating this utility model example with novel above-described embodiment, and is not to this utility model
