Description
Technical field
The invention belongs to unexploded ordnances to destroy technical field, particularly a kind of unexploded ordnance pin based on slag type thermite
Ruin device.
Background technology
Since there is ammunition, just there are the disposal problems for scrapping ammunition, ammunition has certain service life, arrived service life
Ammunition its stability, safety can substantially reduce, and become the waste that must be handled.There is a large amount of waste and old bullet in the whole world every year
Medicine generates, and ammunition disposal is an important link in ammunition entire life cycle.Various regions constantly find and take over largely in recent years
Waste Distillers'Grain, the chemical bullet left including howitzer and aggression against China Japanese army etc., due to the poison of its flammability, explosivity and explosive in itself
Property, great threat is constituted to environment and human survival, is a potential terrified factor, therefore also has become one sternly
The worldwide public hazards of weight.
However many unexploded ordnances are after being found, processing destroy it is very intractable, it is former and with very big danger
Because being：1. kind is complicated, identification is difficult；2. corrosion is serious, safety device failure；3. leaving, the time is long, and performance is unstable.
At present to there are mainly two types of the destroying methods of unexploded ordnance, first, scene explosion is destroyed；Second is that collect after artificially collecting
Middle destruction.But the above method generally requires the machining process of front and continued, and is limited by the harshness of site requirements,
Can also generate the subsidiary explosion hazard effect such as fragmentation, explosion wave, Explosion Seismic Waves when destroying, thus human contact or
Mobile unexploded ordnance has very big danger.
Invention content
The purpose of the present invention is to provide a kind of unexploded ordnances based on slag type thermite to destroy device.
Realize the object of the invention technical solution be：A kind of unexploded ordnance based on slag type thermite destroys device
Tool, including igniter, main charge and housing, the igniter includes electric igniter and ignition charge, and the main charge is
Incendivity forms the thermite powder column of high-temperature liquid state slag, and the housing includes destroying device outer sleeve, destroys device inner sleeve and set
The top closure and the product exit for slag outflow of cylinder top interference fit.Present invention innovation employs inner-outer sleeve cartridge type
Structure rather than simple single hull, and eight elongated slots are uniformly preset on interior sleeve wall, so as to fulfill ignition charge is worked as
After being ignited, the thermite of top layer burns formed slag, will not be accumulated in housing always, until all powder charges are all fired
It is just flowed away after burning down, but can be by the elongated slot on inner sleeve barrel, the channel between inner sleeve and outer sleeve
It is middle to flow away, the drawbacks of being merely able to go out by product exit this flow channels so as to avoid slag, it ensure that pin
The flow velocity of slag can be played certain control action by ruining device, and slag uniform speed slow, continuous intensively act on is enable to treat
On the housing of destroying ammunition, and then achieve the purpose that safe and reliable destroying ammunition.
Preferably, considering the factors such as economy, heat resistance and craftsmanship, the destruction device case material is common
Metal material, such as mild steel, aluminium alloy.
Preferably, the ignition charge is the mixture of potassium nitrate, aluminium powder and sulphur, it can be ignited ignition charge in this way
After can release a large amount of energy, which is enough the main charge that ignites.
Preferably, this destruction device is ignited ignition charge by electric igniter, immediately using sparking mode from top to bottom
Ignition charge to light top layer's thermite, main charge all ignite successively from top to bottom later, so as to ensure igniting when
Stability.
Preferably, the side for exporting energy, ignition temperature, the fusing point of combustion oxidation object and materials of trade-off fuel
Just all many factors such as property, economy choose aluminium powder (Al) as the fuel agent in the main charge, it is sub- to choose oxidation respectively
Copper (Cu2O), iron oxide (Fe2O3), manganese dioxide (MnO2) as the metal onidiges in the main charge, according to each reaction
Stoichiometric ratio calculates the proportion of each ingredient and required content in main charge；Polytetrafluoroethyl-ne is added in powder charge simultaneously
Alkene is as binding agent, to ensure that powder charge can preferably be compacted shape.According to the stoichiometric ratio of each reaction, calculate three kinds and match
The required content of heterogeneity and ratio are respectively in square thermite：
Al+Cu2O+ polytetrafluoroethylene (PTFE)=10%+80.9%+9.1%；
Al+Fe2O3+ polytetrafluoroethylene (PTFE)=22.7%+62.2%+9.1%；
Al+MnO2+ polytetrafluoroethylene (PTFE)=26.4%+64.5%+9.1%.
Compared with prior art, the present invention its remarkable advantage is：1) unexploded based on slag type thermite of the invention
It is a kind of novel unexploded ordnance apparatus for destroying that medicine, which destroys device, and the present apparatus can destroy the bad unexploded ordnance of stability on the spot,
Personnel need not be in direct contact unexploded ordnance, without mobile or any to unexploded ordnance progress mechanical processing process, reduce and turn
Risk during fortune；2) operation procedure is simple to operation, and Destruction is safe and reliable, reduces the requirement to destroying place,
Increase the convenience in Destruction；3) ammunition of big dose can be made not generate surrounding enviroment in Destruction to break
Bad effect will not form secondary pollution and additional explosion hazard.
The present invention is described in further detail below in conjunction with the accompanying drawings.
