Abstract
The invention discloses a forming explosive column/block mechanical disruption device which mainly comprises a charge-in barrel, a disruption barrel, a distance-changeable worm, a sieve plate, a material-collecting barrel and a support, when a disruption explosive column/block is completely immerged in the water environment, a speed-regulating motor is used for driving the distance-changeable worm to slowly rotate. Pressure capable of ensuring that the explosive column/block reaches the disruption intensity is acted on the explosive column/block according to the squeezing and conveying principle of a screw, and accordingly the explosive column/block is crumbled. Rotating of the distance-changeable can gradually disrupt an explosive block into small uniform explosive partials from above down in a gradation mode, the small explosive partials are conveyed to the sieve plate connected with the low end of the disruption barrel, and the sizes of the finally obtained explosive partials are about 2mm-4mm by sieving of the sieve plate. The sizes of the explosive partials after being disrupted can be controlled through replacement of sieve plate s with different sizes of hole space, and control of particle size after cracking of the disruption partials and uniformity of granularity of the explosive column/block are achieved.
Description
Technical field
The invention belongs to machinery manufacturing technology field, relate to a kind of Mechanical Crushing device, relate in particular to a kind of packaged explosive post/piece Mechanical Crushing device.
Background technology
Be focus and the difficult point of research both at home and abroad for the recycling of waste and old fiery explosive always, especially for compressing powder column/piece, before it is recycled, it must be broken into to the more uniform fine grained of fineness ratio.At present the fragmentation of shaped charge/piece mainly contained to two kinds of modes: a kind of is to adopt alligator to carry out fragmentation; Another kind of mode is to adopt kibbler roll to carry out fragmentation, these two kinds of crumbling methods have two large shortcomings: the one, and its operation principle is all to give the quick high shock pressure that one of explosive column/piece is greater than its compression strength, it is broken, because explosive is a kind of material that focus produces detonation that very easily forms under extraneous impact force action, therefore its danger is very high, often appear in shattering process explosive charge occurs, cause casualties and the accident of device damage; The 2nd, the blasting explosive granules size that these two kinds of mode fragmentations obtain is uncontrollable, and particle size uniformity is very poor, brings very large difficulty to follow-up recovery process.In view of above two large shortcomings, usually for shaped charge/piece, substantially can't effectively reclaim and utilize, but directly burn or ignite destruction, this has not only caused huge economic loss, pollution and the destruction of also having caused environment simultaneously.
