Shown in Figure 2 is structural representation after the static mixer shown in Figure 1 combination.
Shown in Figure 3 is the structural representation of the another kind of embodiment of the application's static mixer.
Embodiment
Below in conjunction with accompanying drawing the application is further specified.
Be illustrated in figure 1 as the decomposition texture synoptic diagram of a kind of embodiment of the application's static mixer, shown in Figure 2 is structural representation after the combination of static mixer shown in Figure 1.
Comprise mixing tank sleeve 1; Mixing tank joint 2; Mixing tank joint 2 one ends are connected with drug-transmitting pipe, link to each other with first mixtinite 3 through being threaded in the other end inner chamber, and the outside links to each other with the front end inner chamber of mixing tank sleeve 1 through being threaded; Cavity 6, the second mixtinites 9 rear portions that form one section larger caliber between the front end face of second mixtinite 9 of the rear end of first mixtinite 3 in the sleeve 1 are the cavity 8 of another larger caliber.
The principle of work of present embodiment is: the drug-transmitting pipe tube chamber flows parcel emulsifying base powder column in the promotion lower edge of rampump pressure in the sensitizing solution water ring, gets into static mixers through mixing tank joint 2, and the front end face of first mixtinite 3 that is arranged in joint 2 inner chambers is vertical with the flow direction of sensitizing solution water ring and emulsifying base powder column; Sensitizing solution water ring and emulsifying base powder column are sheared under the effect of this front end face, carry out the first time and mix, and get into the small-bore through hole 5 of first mixtinite 3 then; Because cross section of fluid channel sharply diminishes, the flow velocity of sensitizing solution and emulsifying base will increase rapidly, thereby in through hole 5, turbulent flow take place; Promptly mix for the second time, when blended sensitizing solution and emulsifying base outflow through hole 5, get in the bigger cavity 6 of cross section of fluid channel; Corresponding sensitizing solution and emulsifying base mixed solution flow velocity slow down turbulent flow just take place; This is to mix for the third time, and during small-bore through hole 7 in getting into second mixtinite 9 once more, the front end face of second mixtinite 9 is sheared sensitizing solution and emulsifying base mixed solution once more; Flow velocity also increases once more when flowing into through hole 7; Be the 4th mixing, when mixed stream flows out through hole 7, when getting into the cavity 8 of larger caliber; Flow velocity slows down once more; Mixed stream further mixes, and is to mix for the 5th time, flows out static mixer and injects through mixed fluid repeatedly and carry out sensitized reaction in the big gun hole and form final emulsion [explosive.
Adopt the application's static mixer; Because the aperture of through hole 5 and through hole 7 is very little; Be preferably 3～5mm, can significantly change the velocity of flow of sensitizing solution and emulsifying base, the while is under the shearing action of the front end face of first mixtinite 3 and second mixtinite 9; Impel mutual shear-mixed between sensitizing solution and the emulsifying base, reach the purpose of short mix.
As another kind of embodiment, as shown in Figure 3, also can sleeve 1 first mixtinite 3 and joint 2 be made of one structure; Compare with the structure of previous embodiment; Though integrative-structure does not have dismountable characteristics, but can simplified processing process, reduce production costs.
Emulsion [explosive can obtain steady detonation must have physical sensitization agent such as sensitization bubble or hollow glass micropearl; Indication chemical sensitizer of the present invention is a sodium nitrite in aqueous solution; Produce the sensitization bubble (also can adopt other sensitizing agent and respective reaction to produce other sensitization bubble) of nitrogen in chemical sensitizer sodium nitrite in aqueous solution and the emulsifying base during an ammonium nitrate generation chemical reaction; The prerequisite that chemical reaction takes place for both is a thorough mixing; Sodium Nitrite is fully contacted with an ammonium nitrate, and concurrent biochemical reaction generates nitrogen bubble.
When the on-site mixed equipment of emulsion [explosive carried out scene filling process of dynamite substrate, emulsifying base did not need sensitization or forbade sensitization before getting into the big gun hole, to guarantee the safety of the process of manufacturing.Static mixer of the present invention is through repeatedly shearing, mix sensitizing agent and emulsifying base, can moment with emulsifying base and Sodium Nitrite thorough mixing, impel sensitizing agent and emulsifying base fully to contact concurrent biochemical reaction and produce sensitization bubble.
