Description
Technical field
The present invention relates to a kind of chemical industry equipment and working method, specifically, relate to a kind of charge device and loading method of emulsion explosive.
Background technology
Emulsion explosive is that general reference is dispersed in the oil phase continuum that contains porous masses such as disperseing bubble or hollow glass micropearl, forms a kind of moisture industrial explosive of emulsion state of water-in-oil-type with droplet emulsifying technology preparation, that make the oxygenant salt aqueous solution.
Emulsion explosive is the product innovation that just grows up the seventies in 20th century.The Blabm of the U.S. in 1969 has set forth emulsion explosives technology at first more all sidedly, and emulsion explosive the earliest is non-detonator sensitivity, must ignite by the relaying priming explosive during use.Afterwards, along with to the going deep into of emulsion explosive research, the emulsion explosive that the later stage finds out had cap-sensitivity equally, and had good water resisting property, and had that blast performance is good, mechanical sensitivity is low and advantage such as security is good, and the while cost is lower than water gel explosive.At present, emulsion explosive at home and abroad is widely used.
Emulsion explosive all is made of aqueous inorganic oxidizer salt solutions such as ammonium nitrate and oil phase fuel element usually, does not generally contain single chmical compound explosive.Scorching hot nuclear theory during according to explosive initiation, the scorching hot point when the countless micro-bubbles that are uniform-distribution with in such explosive just become explosive initiation.That is under detonating the mechanical energy effect of momentum in the external world by adiabatic compression, mechanical energy is converted into heat energy, the continuous heat temperature raising of micro-bubble forms the scorching hot point of series of temperature up to 400-600 ℃ at the utmost point of 10.3-10.5s, thereby excites explosive detonation in the short period of time.
To produce scorching hot point in the explosive in order making, to obtain necessary detonation susceptibility and enough explosion energies, add material such as perlite, the hollow glass micropearl etc. that are loaded with bubble, both can do density adjuster, can play sensibilized again at mixed processes.
Emulsion explosive has density height, explosion velocity is big, brisance is high, water repelling property is good, critical diameter is little, Sensitivity to Primary Explosion is good characteristics, has the detonator susceptibility under the minor diameter situation, and general controllable density system is to 1.05～1.25g/cm
3, explosion velocity is 3500～5000m/s.It does not adopt fiery explosive usually is sensitizing agent, and production safety is polluted few.
Emulsion explosive film charge machine is a major equipment of producing emulsion explosive, and existing emulsion explosive film charge machine all adopts single channel to carry, and output is little, and efficient is low.
In addition, these charge machines mostly adopt vane pump to carry.Because vane pump constantly pushes the formation conveying by cam and blade to explosive, make explosive between metal, produce and grind or friction, exist serious potential safety hazard, and a large amount of micro-bubbles that contained in the emulsion explosive after the sensitization, in the course of conveying of vane pump, easily destroyed, cause explosive property to descend even inefficacy.
