The continuous expanded ammonium nitrate explosive mixing device is mainly applicable to civil explosive equipment producing enterprises.
Description
Technical field
The utility model belongs to the industrial explosive material production unit, specifically, relates in particular to the continuous medicament-mixing device of a kind of bulking ammonium nitrate explosive.
Background technology
Bulking ammonium nitrate explosive is a kind of safe environment protection type industrial explosive material that is used for reaching the underground explosion engineering in the open, can be divided into rock expanded ammonium nitrate explosive and allowed for use in coal mines bulking ammonium nitrate explosive two big classes according to the difference of use range.Along with the reinforcement of China to safety, environment protection attention degree; bulking ammonium nitrate explosive more and more is subjected to the favor in market; demand increases year by year; and the production of present domestic bulking ammonium nitrate explosive mainly also rests on backward discontinuous, rolling mixes on the mode of production of medicine; promptly adopt Bulking tank to come ammonium nitrate is carried out expanded crystallization, in wheel roller, add wood powder then, oil phase mixes.In this process, the wheel roller mixture is that gradation repeats, and can only mix 200kg at every turn, and needs manually material to be shifted, and whole process is the discontinuous production technique.Therefore, not only efficiency is low for this mode of production, labour intensity big, bigger energy consumption is arranged, and the explosive property instability of producing, and influences the explosion precision, thereby has influence on the accuracy requirement of engineering explosion.
Summary of the invention
The purpose of this utility model provides the continuous medicament-mixing device of a kind of bulking ammonium nitrate explosive, produces the defective that bulking ammonium nitrate explosive lacks serialization, the mixed medicine equipment of automatization in the prior art to overcome.
The utility model is realized by the following technical solutions: the continuous mixing device of a kind of bulking ammonium nitrate explosive, comprise premixed device, the upper end of premixed device is connected with ammonium nitrate feeder, wood powder feeder, oil phase feeding device and salt feeder, and the lower end of premixed device is orderly connected with mixes medicine handling machinery, continuous grinding and mixing machine and medicine of a cold nature handling machinery; The upper end of described ammonium nitrate feeder is orderly connected with premix ammonium nitrate handling machinery, pulverizer and swollen nitre and carries the flame proof belt, and pulverizer is provided with the sealing handling machinery; The oil phase feeding device comprises oil phase preparing tank, oil phase hold-up vessel and oil phase volume pump.
Described sealing handling machinery, premix ammonium nitrate handling machinery, mixed medicine handling machinery and medicine of a cold nature handling machinery preferably adopt the agitator type handling machinery.
Compared with prior art, the beneficial effects of the utility model are: materials such as expanded ammonium nitrate, wood powder, oil phase, salt are according to setting flow, continual premixed device are carried out feed, have therefore guaranteed continuity, the stability of mixed medicine.Charging system has been equipped with accurate measuring apparatus, when mixing medicine, can set flow according to the variant production specification, has not only guaranteed the accuracy of proportioning, has reduced manual operation simultaneously, reduces the unsafe factor of production link greatly.Changed the mode of production of the production half mechanical semi-hand of present domestic bulking ammonium nitrate explosive on the one hand, bulking ammonium nitrate explosive production successfully made the transition from labor-intensive be technology-intensive type, greatly reduced producers' labour intensity, producers are freed from risk environment, thereby reduced the generation probability of occupational illness; On the other hand, install omnidistance continuous and automatic design, expanded, mixed medicine, powder charge link up in order, and the production process mechanization degree is significantly improved, and have realized serialization production.The stability of not only improved intrinsic safety, mixing medicine, quality, the performance of bulking ammonium nitrate explosive can be greatly improved simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
Among the figure: 1, ammonium nitrate is carried the flame proof belt; 2, pulverizer; 3, sealing handling machinery; 4, premix ammonium nitrate handling machinery; 5, oil phase preparing tank; 6, oil phase hold-up vessel; 7, oil phase volume pump; 8, ammonium nitrate feeder; 9, wood powder feeder; 10, salt feeder; 11, premixed device; 12, mix the medicine handling machinery; 13, continuous grinding and mixing machine; 14, medicine of a cold nature handling machinery.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Ammonium nitrate feeder 8, oil phase feeding device, wood powder feeder 9, salt feeder 10 are installed above premixed device 11, are had certain height poor.
When using the utility model, in the appropriate location in workshop its various piece is installed and fixed respectively by support, install electric control system, connecting with the mains gets final product.
Its principle of work is: at first, expanded ammonium nitrate enters in the pulverizer 2 by carrying flame proof belt 1, enters ammonium nitrate feeder 8 by sealing handling machinery 3, premix ammonium nitrate handling machinery 4 after crushed, enters premixed device 11 after metering; The oil phase that wood powder, salt and fusing are good enters premixed device 11 after metering by setting proportioning respectively simultaneously.Various starting material mix after mixed medicine handling machinery 12 enters in the continuous grinding and mixing machine 13 through preliminary in premixed device, the other end from continuous grinding and mixing machine 13 behind thorough mixing enters medicine of a cold nature handling machinery 14, and mixing also, cooled medicinal powder is delivered to subsequent processing by medicine of a cold nature handling machinery 14.Whole device has been guaranteed continuity, the stability of mixed medicine.And accurate measuring apparatus is equipped with, when mixing medicine, can artificially set flow according to the variant production specification, and carry out automatic gauge, mixing.
