The adjustment of the gas flow of supply.
Secondly, reference picture 2, Fig. 3 illustrate the construction of the spiral channel formation body 19 of present embodiment.In addition, Fig. 2 (a)~
Fig. 2 (c) is top view, side view, the upward view of the spiral channel formation body 19 of present embodiment, during Fig. 3 (a) is Fig. 2 (b)
A-A ' sectional views, Fig. 3 (b), (c) are the direction views (removing periphery cylindrical portion) from Fig. 2 (c) B directions, C directions.
As shown in Figure 2,3, the main body 29 of spiral channel formation body 19 is by columned cylindrical portion 29A and from cylindrical portion 29A
The trapezoidal portion 29B of circular cone that protrudes of lower end circular cone trapezoidal shape constitute, in cylindrical portion 29A outer peripheral face, a pair of spiral helicine leaves are set
Piece 30A, 30B.In addition, setting cylindric outside cylindrical portion 31 in spiral blade 30A, 30B outer peripheral edge.In this embodiment party
In formula, the height in outside cylindrical portion 31 is equal for example with cylindrical portion 29A height, the external diameter of the trapezoidal portion 29B of circular cone bottom surface with
Cylindrical portion 29A external diameter is equal.In addition, at the center of main body 29, along cylinder axis (cone axis) formation gas introducing port 25.
In the present embodiment, spiral helicine blade 30A, 30B centered on the central shaft of main body 29 from separating 180 °
Position is risen, respectively along cylindrical portion 29A outer peripheral face throughout (180 °) settings of half cycle.I.e., in the present embodiment, such as 2 heavy corkscrews
Like that, blade is misaligned in the axial direction each other.
In addition, blade 30A, 30B for forming spiral channel are erected in adjacent top surface, formation spiral channel inlet portion 32A,
32B (referring particularly to Fig. 3 (c)).As shown in Fig. 2 (a), spiral channel inlet portion 32A, 32B are located at using the axle of main body 29 in
The angle θ 1 of heart scope, remaining angle θ 2 scope is formed as lead angle certain blade 30A, 30B main part.Angle, θ
1st, θ 2 is respectively set as about 30 °, 150 °, blade 30A, 30B main part (model of angle, θ 2 based on such as 10 ° of tolerance+
Enclose) lead angle be for example set as 5 °~10 °.In addition, spiral channel inlet portion 32A, 32B erect part most end (on
Swim side) it is substantially 90 °.
Secondly, reference picture 1, Fig. 3 illustrate spiral channel formation fixing means of the body 19 to resettlement section 20.
Formed in the connecting portion of the resettlement section 20 of nozzle 11 and reducing diameter part 21 with the thickness with outside cylindrical portion 31 substantially
The stage portion 20A of same dimension width.If spiral channel formation body 19 is installed on into resettlement section 20, then outside cylindrical portion
31 outer peripheral face touches with the inner peripheral surface of resettlement section 20, and the bottom in outside cylindrical portion 31 is abutted with stage portion 20A.
On the other hand, the leading section 12A of liquid supply unit 12 is in and the substantially same diameter in outside cylindrical portion 31, substantially same
The drum of thickness, is installed on after resettlement section 20 by spiral channel formation body 19, liquid supply is installed on nozzle 11
During portion 12, leading section 12A is abutted with the upper end in outside cylindrical portion 31.Thus, the position of spiral channel formation body 19 is being housed
Fixed in portion 20.In addition, in the present embodiment, now, the conus portion 29B of spiral channel formation body 19 front end is located at gas
The entrance height position of liquid mixing unit 22.
Secondly, the gas-liquid two-phase convolution fluid generating process and microbubble generating process of 1 pair of use above structure of reference picture
Outline illustrate.
The pressure fluid supplied to fluid path 17 is from the inlet portion (32A, 32B) of spiral channel formation body 19 along spiral
The blade (30A, 30B) of shape is imported into reducing diameter part 21, and is sprayed to circumferential direction lower section.Circular cone surface helix of the liquid along reducing diameter part 21
It is imported into gas-liquid mixed portion 22, further by speedup, the cylinder inner peripheral surface in an edge gas-liquid mixed portion 22 return at a high speed shape
Rotation is while to the open flow in spray nozzle front end portion.Thus, negative pressure is produced at the center in gas-liquid mixed portion 22, from gas introduction tube 24
Attract gas along the axial gas-liquid mixed portion 22 of cylinder, form gas-liquid two-phase convolution fluid.The gas-liquid two-phase circles round fluid from undergauge
The front end opening in gas-liquid mixed portion 22 spray/scatter to nozzle exterior, gas-liquid two-phase fluid is cut in this process, produced
Anger bubble.
As above, according to present embodiment, due to the spiral shell set on the spiral channel formation body for micro bubble generation device
Revolve the periphery of the blade of shape is strengthened by cylindrical portion, therefore, for the high liquid of pressure, also can assign enough strong to blade
Degree.
In addition, in the present embodiment, setting multiple spiral helicine blades, and make them misaligned in the axial direction, because
This, can form body by integrally formed spiral channel by cast form.But, when so misaligned in the axial direction, then such as
Conventional example can not be made using cohelix Agencies like that, the contraction in length of spiral channel.Therefore, spiral flow help starting (helping away) away from
From shortening, the efficiency of swirling flow is reduced.Although it is contemplated that by increase supply Fluid pressure it is compensated, but when improve pressure and
When increasing the flow velocity of spiral channel, increase in the pressure loss of spiral channel intake section.
Therefore, in the present embodiment, by erecting the intake section of spiral channel, prevent flow direction from drastically changing,
Reduce the generation of loss.Thus, in the present embodiment, due to using cast form, so spiral channel can not only be shortened
Length, but also strong swirling flow can be produced.
In addition, in the present embodiment, spiral spacing is discontinuously changed in inlet portion, but it is also possible to be set in whole spiral shell
Path or inlet portion are revolved, continuously increases the structure of spacing towards entrance.
For example, spiral channel formation body is formed by polyphenylene sulfide (PPS) resin.
In addition, Fig. 4 represents the variation of spiral channel formation body.In the variation shown in Fig. 4, by the He of outside side wall 31
Blade 30A, 30B, the corner of cylindrical portion 29A connections are set to R (shape for forming the bendings such as circular arc), suppress by these wall shapes
Into path in the fluid that circulates in corner produce vortex, reduce resistance.
