Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings:
Referring to Fig. 1, the utility model provides a kind of venturi mixer, connects nozzle 1 including main fluid, introduces fluid Nozzle 2 is connected, sucks room 3, converging transition 4, trunnion section 5, diffuser 6 and nozzle 7.The input end of nozzle 7 is mixed with venturi The sucking room 3 of device is connected through a screw thread.Specifically, the external screw thread 11 of 7 input end straight pipe outer wall of nozzle and sucking 3 inner wall of room Internal thread 12 connects.
Herein, venturi mixer is by sucking the internal thread 12 of 3 inner wall of room and 7 input end input end straight pipe of nozzle The front and rear adjusting of 11 relative position of external screw thread of outer wall achievees the purpose that different mixing liquid measures than adjustment.
Referring to Fig. 2-4, the utility model additionally provides a kind of venturi mixer nozzle, and the outer wall of nozzle 7 is equipped with several Outer lug boss 8, each outer lug boss 8 are extended to the port of export of nozzle 7 by the input end of nozzle 7 in the shape of a spiral, form outer water conservancy diversion Slot, the spiral windings of several outer lug boss 8 is to identical;The inner wall of nozzle 7 is equipped with several inner convex platforms 9, and each inner convex platform 9 is in spiral shell Rotation shape is extended to the port of export of nozzle 7 by the input end of nozzle 7, diversion trench in formation, and the spiral windings of several inner convex platforms 9 is to phase Together;The spiral winding of inner convex platform 9 and outer lug boss 8 is to opposite.
Wherein, 8 height of outer lug boss determines that 9 height of inner convex platform is determined according to main fluid viscosity according to fluid viscosity is introduced.
Preferably, the quantity of outer lug boss 8 is two, and two outer lug boss are symmetrical arranged along the circumferential direction of nozzle 7.Inner convex platform 9 Quantity is four, and four inner convex platforms are uniformly distributed along the circumferential direction of nozzle 7.
Preferably, the vertical view of outer lug boss 8 is approximately semicircle shape, and the vertical view of inner convex platform 9 is approximately quadrant arcuation.
In the utility model, the port of export of nozzle 7 is equipped with alveolus 9 with the intersection of inner convex platform 9.Preferably, nozzle 7 The intersection of the port of export and each inner convex platform 9 is equipped with alveolus 9.
The principle of the utility model is:Main fluid connects nozzle 1 by main fluid and enters in nozzle 7, due to 7 section of nozzle It constantly reduces, until flow velocity fast whole rise during front end, high-velocity fluid causes sucking 3 pressure of room to reduce, and drives liquid in sucking room 3 Trunnion section 5 is quickly entered by converging transition 4 to be mixed and flow into diffuser 6, since 6 section of diffuser starts to increase rapidly, is made Liquid volume expands pulverization, is sufficiently mixed, so as to reach mixing purpose.Herein, master is passed through during two kinds of fluid mixing The quick jet stream of fluid, which drives, introduces fluid flowing mixing, generates shunting in mixed flow moment, crosses over many times mixing and reversely rotation Stream reaches rapid, is equably spread in entire fluid, achievees the purpose that moment rapidly and efficiently mixes.
Venturi mixer is while above-mentioned mixing is completed, when main fluid connects nozzle 1 into nozzle 7 by main fluid While flow velocity increases, interior diversion trench is formed by nozzle 7 inner wall, 4 inner convex platforms 9, makes part edge side liquid tangent line by nozzle 7 Front end deflects when spraying at a high speed.It introduces fluid and fluidly connects nozzle 2 into sucking room 3 by introducing, under main fluid drive While flowing to trunnion section 5, the outer lug boss 8 of segment fluid flow and 7 outer wall of nozzle forms outer return guide trough into reverse deflection, finally Fluid is made to collide with main fluid, and generates and divides in mixed flow moment, layering, mixing is crossed over many times and reaches rapid, uniform Ground is spread in entire fluid, realizes that mixing efficiency improves.Main fluid in the nozzle 7 to trunnion 5 flow at high speed of section when, due to interior The stickiness that boss 9 makes the flow direction of segment fluid flow deflect between fluid causes shearing force that energy, momentum is brought to transfer, and makes Part edge side main fluid generates pulsation, and the automatic fine tuning stream under hydraulic action when being sprayed by alveolus 9 within the specific limits To mixed effect is strengthened, increase flow-disturbing effect, achieved the purpose that efficient mixing.Composite rate is up to more than 90%-95%.
The utility model by main fluid and introduce fluid boundary a fluid stream change realize shunting, layering, cross-mixing, It is finally reached the purpose rapidly and efficiently mixed.Former mixer nozzle need to be only replaced in having venturi mixer with regard to energy Realize efficiently mixing purpose.It is easy to operate understandable with simple in structure, it can be used under without mechanical dynamic environment and dirty without environment Dye.Mixing apparatus investment cost can be reduced after implementation and improves mixing efficiency.
