Embodiment Construction

[0023] When the charge explodes in the air, the explosive product rapidly expands outward due to the huge pressure of the explosive product. The expanding explosion product compresses the surrounding air like an accelerating piston. Because the explosion product initially compressed the surrounding air medium at a very high speed, its pressure, density and temperature increased suddenly, forming a very high pressure initial shock wave (about 10 8 Magnitude of Pa). As the explosion product continues to expand, there will be sparse waves propagating inward along the explosion product. When the sparse wave front propagates to the core, the pressure at the core begins to drop.

[0024] For different distances, the target bears different effects. In the closest distance to the explosion center, the target is mainly affected by the explosive products: when the distance between the charge and the target is less than (10-20) r0, where r0 is the radius of the charge, the target is affec...

Abstract

The invention discloses a waste explosive exploding and destroying device. The waste explosive exploding and destroying device comprises a main structure (1) and an outer protection wall (3) which are arranged on a foundation structure (5); the main structure (1) comprises a top wall (11) of a spherical crown structure and a side wall (12) of a cylindrical structure; a plurality of inlets and outlets (4) are formed in the side wall (12), the outer protection wall (3) is arranged at the position, right facing the inlets and outlets (4), of the outer portion of the main structure (1), and a plurality of exhaust holes (2) are formed in the top wall (11). Impact waves generated by explosives can be effectively absorbed and relieved, the damage effect of fragments is controlled, the explosive fragments are prevented from flying out, and the service life of the device is prolonged by replacing a lining.

Description

Technical field [0001] The invention belongs to the field of detonation, and in particular relates to an explosive destruction device for waste explosives. Background technique [0002] In the explosive destruction of waste explosives, because the explosive explodes on the ground in the destruction facility, it will cause damage to the entire structure. The part acting in the air direction will destroy surrounding targets in the form of explosive shock waves and explosive products, and the part acting in the direction of the ground will carry out energy propagation and destruction in the form of seismic waves. These two types of destructive loads have a major destructive effect on the structure of the entire facility, so how to weaken the shock wave and seismic wave and to remove and unload the explosive products to ensure the safety of the facility is the focus of the structure. At the same time, the effect of the explosive products will cause the shell of the charge and the su...
