Structure schematic diagram.The boss 311 that the tube wall of sparge pipe 31 is equipped with for changing liquid flow direction in sparge pipe 31, spray head 32 are set
It sets and is on position that boss 311 is opposite, thus it is possible to vary the flow direction of liquid in sparge pipe 31 increases liquid and flows to spray head 32
Internal impulse force.Liquid in sparge pipe 31 flows in one direction, and the fluoran stream surface 312 of boss 311 is smoothly to rise from tube wall
Cambered surface, allow fluid to pour inside the change direction spray head 32 along cambered surface.Wherein, spray head 32 can rotate in a circumferential direction fixation
On sparge pipe 31, the bottom 321 that spray head 32 is connect with sparge pipe 31 is equipped with inclined groove 322, and inclined groove 322 is along spray head
The arrangement of 32 internal circumferentials.Liquid in sparge pipe 31 is under the action of 311 cambered surface of boss to the inclined groove of 32 bottom 321 of spray head
322 impacts, the cell wall of inclined groove 322 are rotated with respect to sparge pipe 31 by making spray head 32 after the power of liquid.Spray head 32
Be equipped with it is multiple for liquid spray spray orifices 323, spray orifice 323 be obliquely installed and the aperture of spray orifice 323 along water (flow) direction by
It is decrescence small.The shape for the atomized liquid that spray head 32 is sprayed in static sprinkling is not uniform, but when spray head 32 is in water flow
When rotating under impact, it is ensured that the spray shapes that spray head 32 sprays, to ensure that spray effect.As shown in Figure 5
It is convex in order to there is another part liquid to go successively in sparge pipe 31 after guaranteeing on hydraulic shock to boss 311 in sectional view
Platform 311, which is equipped with, makes to impact the through-hole 313 that the partially liq in cambered surface continues flowing by boss 311.While in order to guarantee
The aperture of hydraulic pressure, through-hole 313 is gradually reduced along water (flow) direction.
It is as shown in FIG. 7 and 8 the structural schematic diagram of shell 21 and mixing mill 22 in mixing arrangement 2.Mixing arrangement 2 includes shell
Body 21, the interior mixing mill 22 being equipped with for gas-liquid mixed of shell 21, inlet 210, air inlet 211 and liquid outlet 212 are provided with
On shell 21.One side end face of mixing mill 22 is rotatably connected with the cut surface inner sealing of shell 21, and cut surface, which is equipped with, to be used
Both make uniformly mixed cutting groove 213 in cutting liquids and gases and the mounting groove 214 for installing mixing mill 22, mixing mill
22 are rotatably disposed in shell 21 by mounting groove 214, and the end face that mixing mill 22 is in contact with cut surface is equipped with and cutting
Slot 213 matches the circulation groove 220 of cutting.Cutting groove 213 be equipped with it is multiple, multiple cutting grooves 213 along mixing mill 22 rotation
Direction is circumferentially uniformly distributed, and the position of circulation groove 220 and the position of cutting groove 213 are correspondingly arranged.
As shown in FIG. 7 and 8, the shape of the cutting groove 213 in the present embodiment is sector, 213 edge of cutting groove of multiple sectors
Circular end face circumferential array, can make full use of the surface of circular end face.Mixing mill 22 offer circulation groove 220 end face and
The cut surface of shell 21 connects, and liquids and gases pass through inlet 210 respectively and air inlet 211 enters corresponding cutting groove
In 213.Only have in cutting groove 213 locating for inlet 210 at this time and contain liquid, contains in cutting groove 213 locating for air inlet 211
There is gas, mixing mill 22 rotates, and the gas and liquid in different cutting grooves 213 start to mix, inlet 210 and out liquid at this time
Mouth 212 continues to inject gas and liquid into mixing arrangement 2 respectively.The phase of gas and liquid in cutting groove 213 and circulation groove 220
It is mutually mutually mixed under cutting, the gas that incorporates in liquid increases and can be containing the lesser bubble of diameter, gas in a liquid molten
Solution amount and bubble diameter are determined by the revolving speed of mixing mill 22.
