Description
Technical field
The utility model relates to a kind of industrial explosive material industry mechanical stirring mixing equipment, especially a kind of be applicable to bulking ammonium nitrate explosive in producing expanded ammonium nitrate and the spraying mixing stirring device of compound oil phase mixed processes.
Background technology
Bulking ammonium nitrate explosive belongs to oxidation-reduction type mechanically mixing explosive, " focus " initiation theory and explosive reaction mechanism according to explosive, in the pyrotechnic composition thin more, the medicine grain of the particle of various components more " disproportionation ", mix even more, it is tight more to be that oxygenant contacts with combustible agent, then required detonating can be more little, explosive reaction speed is fast more, complete more, and blast performance is also high more.Existing ammonium nitrate bulking process and equipment have solved ammonium nitrate grain refine, disproportionation, and these improve the factor of explosion properties.But handle in these production factors of component mixing uniformity, even there are some problems in existing equipment.
The existing pharmaceutical worker's preface of mixing uses three feed mixers to mix the major equipment that contacts as the ammonium nitrate powder with compound oil phase.Three feed mixers adopt compound oil phase from up to down the mode of expanded ammonium nitrate powder spray in the cone mixer to be realized mixing.Find in the production: single shower nozzle spray effect is not high, in the cone mixer expanded ammonium nitrate powder can not with the fine uniform mixing of compound oil phase; Spray orifice makes that more greatly compounded oil phase particle diameter is bigger, and the refinement degree is relatively poor, and atomizing effect is bad, and shower nozzle mouth spray place attaches the medicine body and makes the compounded oil spray out be gathered into mutually to drip even become liquid stream shape; Relative its below ammonium nitrate particulate spray of stir shaft with blade shield portions compounded oil.The problems referred to above make the medicine body blend local ammonium nitrate powder occur and do not contact the compound oil phase of compound oil phase drawn game portion and drip the situation that attaches too much ammonium nitrate powder, cause mix inhomogeneous.
Summary of the invention
The utility model provides a kind of can realize expanded ammonium nitrate, the mixed uniformly spraying mixing stirring device of compound oil phase.
For achieving the above object, the utility model is explained a kind of spraying mixing stirring device, by motor, drug administration device and medicament-mixing device are formed, the output shaft of described motor is connected with the main shaft that described drug administration device is installed, on the described main shaft conveyor screw is installed, upper front end at described drug administration device is provided with charging opening, the end of described drug administration device is connected with the feeding opening of described medicament-mixing device, its key is: described main shaft stretches in the described medicament-mixing device vertically, and pass described medicament-mixing device tail end, at least one group of stirring rake is installed on the main shaft in stretching into described medicament-mixing device, on described medicament-mixing device top at least one shower nozzle is installed, is provided with medicine outlet in the afterbody lower end of described medicament-mixing device.
Machine operation, add expanded ammonium nitrate from charging opening, conveyor screw is transported to the expanded ammonium nitrate that enters drug administration device in the medicament-mixing device, a series of shower nozzles of installing on medicament-mixing device top spray compound oil phase, expanded ammonium nitrate fully mixes with compound oil phase under the stirring rake effect, and under stirring rake pushing effect backward, move backward, by the medicine outlet output of medicament-mixing device bottom.
A series of shower nozzles are installed in medicament-mixing device top, and shower nozzle is sprayed downwards, and the spray orifice aperture of this shower nozzle is less, make from the compound oil phase droplet particle of shower nozzle ejection tinyly, and atomizing effect is good, and droplet particle and expanded ammonium nitrate are at medicament-mixing device uniform mixing more.
Described medicament-mixing device is a horizontal cavity with certain taper.
Because medicament-mixing device is cone-shaped, be beneficial to mixed expanded ammonium nitrate along sliding to medicine outlet output under the cavity.
Every group of described stirring rake all formed along the symmetric stirring rake of described main shaft by two, two stirring rakes of every group are all perpendicular to described main shaft, and the axis of two stirring rakes of every group all overlaps, two groups of adjacent stirring rakes are " ten " font along described major axes orientation projection arbitrarily, and the agitating vane of described stirring rake outer end all inclination is installed.
A plurality of stirring rake groups are installed on the main shaft in the medicament-mixing device, the agitating vane inclination of stirring rake is installed, stirring rake is with main axis rotation, make expanded ammonium nitrate and compound oil phase form motions such as violent convection current, shearing, diffusion, produce three-dimensional mixing effect, stir, expanded ammonium nitrate and compound oil phase mix, improved explosive property, production efficiency height, stirring rake can also promote mixed expanded ammonium nitrate and move to the medicine outlet direction.
Described shower nozzle all is installed in the top between the two adjacent groups stirring rake.
Shower nozzle is installed in top, two adjacent groups stirring rake mid-way, avoid stirring rake to shelter from the compounded oil spray of its below ammonium nitrate powder relatively, optimize spray effect, simultaneously because shower nozzle is in the powder moving region, shower nozzle is difficult for attaching the medicine body, avoids mist attitude oil phase to assemble.
Unusual effect: the compound oil phase atomization of liquid and spray are effective, and can avoid mist attitude oil phase to assemble, and the medicament-mixing device mixing effect is good, and compound oil phase and expanded ammonium nitrate mix, and have improved explosive property, the production efficiency height.
