Summary of the invention
The object of the present invention is to provide a kind of direction, shearing mutually, mixing, shunting, concentrated of passing through constantly two kinds of materials of change, reach the static mixer that Quick uniform mixes.
Technical scheme of the present invention comprises:
A kind of static mixer, it is characterized in that: comprise a runner, in described runner, comprise mixed once body and secondary mixture, described mixed once body is positioned at runner leading portion, its front end face is vertical with the flow direction of runner, and in mixed once body, be provided with small-bore through hole (5), runner between described secondary mixture and mixed once body and after secondary mixture is heavy caliber runner, the front end face of secondary mixture is vertical with the flow direction of runner, and in secondary mixture, is provided with small-bore through hole (7).
Further, the aperture of described through hole (5) is 3～5mm.
Further, the aperture of described through hole (7) is 3～5mm.
Further, described static mixer also comprises connecting the joint (2) of drug-transmitting pipe.
Further, the mode that described mixed once body is threaded connection is fixed on static mixer runner leading portion.
In static mixer of the present invention by the first mixture and the second mixture are set in runner, the front end face of the first mixture flows to vertical with runner, can mix for the first time so that sensitizing solution water ring and emulsifying base powder column are sheared generation mutually, then enter the small-bore duct in the first mixture, because cross section of fluid channel diminishes, mixed sensitizing solution and emulsifying base accelerate suddenly after entering small-bore runner for the first time, and mix for the second time in small-bore runner, mixed stream is after going out small-bore runner, enter the tube chamber before the second mixture that bore is larger, because space becomes large, flow velocity reduces, in this tube chamber, mix for the third time, and then enter the small-bore runner in the second mixture, carrying out the 4th time mixes, when flowing out this small-bore runner, carrying out the 5th time mixes.
Because the bore of small-bore runner can adopt very little size, as 3～5mm, can be so that velocity variations to be very fast, turbulent more remarkable effect, reaches object and the effect of short mix.

Embodiment
Below in conjunction with accompanying drawing, the application is described further.
Be illustrated in figure 1 the decomposition texture schematic diagram of a kind of embodiment of the application's static mixer, Figure 2 shows that the structural representation after the combination of the static mixer shown in Fig. 1.
Comprise mixing tank sleeve 1, mixing tank joint 2, mixing tank joint 2 one end are connected with drug-transmitting pipe, in the other end inner chamber, be threaded connection with the first mixture 3 and be connected, outside is threaded connection with the front end inner chamber of mixing tank sleeve 1 and is connected, the cavity 8 that the rear end of the first mixture 3 is another larger caliber apart from cavity 6, the second mixture 9 rear portions that form one section of larger caliber between the front end face of the second mixture 9 in sleeve 1.
The principle of work of the present embodiment is: in sensitizing solution water ring, wrap up emulsifying base powder column and along drug-transmitting pipe tube chamber, flow under the promotion of ram pump pressure, through mixing tank joint 2, enter static mixer, the front end face of the first mixture 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, mix for the first time, then enter the small-bore through hole 5 of the first mixture 3, 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, there is turbulent flow, mix for the second time, when the sensitizing solution mixing and emulsifying base outflow through hole 5, enter in the cavity 6 that cross section of fluid channel is larger, corresponding sensitizing solution and emulsifying base mixed solution flow velocity slow down turbulent flow just occur, this is for mixing for the third time, during small-bore through hole 7 in again entering the second mixture 9, the front end face of the second mixture 9 is sheared again to sensitizing solution and emulsifying base mixed solution, while flowing into through hole 7, flow velocity also increases again, be to mix for the 4th time, when mixed stream flows out through hole 7, while entering the cavity 8 of larger caliber, flow velocity slows down again, mixed stream further mixes, be to mix for the 5th time, through mixed fluid repeatedly, flow out static mixer and inject and in big gun hole, carry out sensitized reaction 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, while is under the shearing action of the front end face of the first mixture 3 and the second mixture 9, impel mutual shear-mixed between sensitizing solution and emulsifying base, reach the object of short mix.
