Specific embodiment
Referring to Fig. 1 to Fig. 4, elaborate to the utility model.It should be pointed out that the utility model can be with
Many different modes are realized, however it is not limited to embodiment described herein, on the contrary, the purpose of these embodiments are provided be in order to
Make those skilled in the art to content understanding disclosed in the utility model more thorough and comprehensive.
With reference to Fig. 1, a kind of micro-nano bubble generator 100 and goes out liquid direction as shown by arrows 500 at liquid feed liquor, occurs
Device main body 110 is hollow form (See Figure 2), and in the present embodiment, generator main body 110 can be but be not intended to be limited to metal such as
Stainless steel, copper etc. or tubulose have chrome-faced or other anti-material of coating to get rusty etc., in addition, occurring
Device main body 110 can be integrally machined molding or block assembly.Generator main body 110 includes being set to generation
The inlet 111 of the head end of device main body 110 and be set to generator main body 110 tail end liquid outlet 118, for the ease of micro-nano
The connection of rice bubble generator 100 and other devices such as spray equipment, the head end of generator main body 110 are provided with the first threaded portion
112, further, it is connect for the ease of micro-nano bubble generator 100 with conveying the pipeline of external liquid, inlet 111
Second threaded portion 119 (See Figure 2) is set in interior wall, to be connected with the pipe fitting of pipeline for conveying external liquid.
After micro-nano bubble generator 100 is installed to other devices, to prevent installation leak etc. from entering generator main body
110 exterior wall on the inlet 111 of generator main body 110 and the exterior wall respectively held of liquid outlet 118, is respectively arranged with
For installing the groove 113,116,117 of sealing ring.
With reference to Fig. 2, the inlet 111 of generator main body 110 is disposed with gas-liquid mixed portion between liquid outlet 118
120th, the shearing at least two layers strainer 141 (with reference to Fig. 3) filters out portion 140.In the present embodiment, the gas of gas-liquid mixed refers to
It is air, but not makes restriction, such as can also be ozone in other embodiments, liquid refers to tap water, similarly
Restriction is not made, such as can also be industrial water, breeding water in other embodiments or other gas-liquid may be needed to mix
Liquid of conjunction etc..
Gas-liquid mixed portion 120 includes penetrating through to liquid along 110 exterior wall of generator main body at liquid handling portion 124 and at least one
The suction hole 115 of body processing unit 124.
Liquid handling portion 124 includes section and gradually contracts along the direction (i.e. the direction of arrow 500) by inlet to liquid outlet
Small contraction section 121, the mixing section 122 connected with air entry, section are along direction (the i.e. arrow 500 by inlet to liquid outlet
Direction) gradually increased expansion segment 123.
In the present embodiment, suction hole 115 is penetrated through to mixing section 122, since mixing section 122 is in liquid handling portion 124
Section is minimum, and therefore, suction hole 115 is penetrated through to mixing section 122, and also more conducively gas-liquid is sufficiently mixed.
In addition, suction hole 115 may be set to be externally wall to liquid handling portion 124, the diminishing shape in section
Or chamfering is set at exterior wall, to ensure to suck more gases.
Further, 110 exterior wall of generator main body is provided with cricoid groove 114, and suction hole 115 is arranged on recessed
In slot 114.After micro-nano bubble generator 100 is installed to other device, setting groove 114 can ensure regardless of micro-nano gas
It steeps generator 100 to install with which angle, can ensure that suction hole 115 connects always with external air source.
Further, suction hole 115 can set many places according to actual needs.
With reference to Fig. 2, Fig. 3, shearing, which filters out portion 140, can include two layers of strainer, along the direction by inlet to liquid outlet (i.e.
The direction of arrow 500) the first strainer 141, stripper loop 142, the second strainer 143, fixing piece 144 are disposed with, liquid is
Cushion space is formed between one strainer 141, the second strainer 143, generates turbulent flow to increase containing for liquid simultaneously in elimination air pocket
Tolerance.Furthermore it is possible to multistorey strainer mesh is set according to actual needs.
In order to while shearing filters out portion 140 and generates strong turbulent flow as far as possible, reduce back pressure as far as possible, shearing filters out portion
140 can preferably set multistorey strainer mesh, and each layer strainer is separated using above-mentioned for separating the stripper loop 142 of each layer strainer, with
Form cushion space above-mentioned at 2-8.
Further, strainer be hydrophobic metal net, mesh number 200#-8000#.In practical combination, two are such as used
During layer strainer, the mesh number that can set the first strainer 141 is 200#-800#, and 143 mesh number of the second strainer is 800#-
8000# is filtered out with realizing preferably to shear the liquid after gas-liquid mixed.
Further, in the combination of other multistorey strainer meshes, could be provided as each layer strainer along by inlet to going out liquid
The direction (i.e. the direction of arrow 500) of mouth, the mesh number of each strainer is at least identical or successively increases, to realize the turbulent flow in generation
The sequential control of middle shearing air pocket, the air content for increasing liquid, the size of the micro-nano bubble of control.
Influence of the combination of the number of plies about cushion space, different strainers to the micro-nano bubble of generation, the present inventor into
A large amount of decontamination of going is tested, and since micro-nano number of bubbles is bigger, bubble is smaller, dirty removal capacities are stronger, because passing through sight
Examine the number of plies with different cushion spaces, the micro-nano bubble generator of combination of different strainer shears the reality of the water filtered out
Dirty removal capacities can be directly opposite the effect for the micro-nano bubble for being inferred to its generation.With reference to following table
| Test serial number | Cushion space | Screen pack (along the direction of arrow 500) | Scavenging effect (emulsification of range estimation water body) |
| 1 | 3 | 2000#-2000#-800#-800# | A small amount of air pocket, effect are general |
| 2 | 3 | 2000#-800#-2000#-800# | A small amount of air pocket, effect are slightly good |
| 3 | 3 | 800#-2000#-800#-2000# | A large amount of microbubbles, effect are slightly good |
| 4 | 3 | 800#-800#-2000#-2000# | A large amount of microbubbles, effect are more preferable |
| 5 | 6 | 2000#-800#-800#-400#-400#-400#-400# | Less air pocket, effect are general |
| 6 | 6 | 2000#-400#-400#-400#-400#-400#-800# | Less air pocket, effect are slightly good |
| 7 | 6 | 200#-200#-400#-400#-800#-800#-2000# | A large amount of microbubbles, effect are more preferable |
| 8 | 6 | 400#-400#-400#-400#-800#-800#-2000# | A large amount of microbubbles, effect are fabulous |
It should be noted that each experiment that above table is shown is shown in the multiple combinations that inventor is done
The experiment effect of part combination, and not make restriction, 4,5,7,8 layers of cushion space or the experiment number of other screen pack
According to not listing one by one herein.With reference to upper table, it can be deduced that, in the case where cushion space is identical, the mesh number of strainer it is identical or
When person successively increases, the micro-nano bubble effect of generation is more preferable.In addition, when cushion space is more, generated micro-nano gas
It is more preferable to steep effect.
In addition, the screen pack that shearing filters out portion 140 can also be other with flexible microporous hydrophobic nano material,
And there should be flexible microporous hydrophobic nano material, it is necessary to be wanted before the use by reprocessing with the use for meeting strainer
It asks, realizes preferably hydrophobic.
Fixing piece 144 filters out the strainer in portion 140 for fixed shear.In the present embodiment, fixing piece 144 could be provided as
With externally threaded hollow form, and the reverse side in the end face abutted with strainer be provided with for fixing piece 144 by cross recess or
