Design of the Fragment-emission-proof Anti-blast Enhanced Fuze Destructor
Wang Don · Explosive Materials · 2015
A fragment-emission-proof anti-blast enhanced destructor was designed to resolve the following problems:incomplete induced detonation and hazardous objects emission in destroying waste fuzes by explosion,and insufficient blast resistant ability of existing fuze destructor. The body of the destructor was formed by one-time casting,and it could meet the need of destroying a large amount of fuzes. The fire nozzle was designed to form a certain downward angle with the inner circle tangent of the furnace body and the horizontal line,thus to prevent the explosion fragments from damaging the fire nozzle,and to improve the utility efficiency and service life of the destructor. The bottom tilting slagging improved the operability and working efficiency of the furnace. And the design of automatic temperature control and automatic ignition improved the automation level of the destructor,reducing the manual operation intensity and the probability of mistaken operations. In verification experiment,waste fuze below 200 g TNT equivalent could be completely burned by this destructor safely and reliably,which meets the destruction requirements of waste,old fuze and initiating explosive devices.
