Hollow ball filled airtight spherical explosion-proof container

Abstract

The invention provides a closed spherical anti-explosion container filled with hollow balls. The closed spherical anti-explosion container is simple in structure, convenient to operate and high in anti-explosion capacity. The closed spherical anti-explosion container comprises two symmetrical hemispheres. Each hemisphere comprises an inner face plate, an outer face plate and the plurality of hollow balls, wherein the inner face plate and the outer face plate are each arranged in a hemispherical face manner, and the portion between the inner face plate and the outer face plate is filled with the hollow balls. Flanges are fixed to the end face of the outer face plate. The two hemispheres are connected through the flanges, fixed to each other, to form a closed cavity sphere. Spherical cavities defined by the inner face plates are used for containing explosives. At least one filling hollow ball layer where the hollow balls are evenly and densely distributed is formed between each inner face plate and the corresponding outer face plate. Due to the adoption of the hollow ball filling structure, the weight of the anti-explosion container can be remarkably reduced. The explosion energy is absorbed by making the inner face plates and the filling hollow ball layers elastically deform, and the capacity of the anti-explosion container for resisting the explosion impact is improved. The hollow ball filling can be designed to be in a single-layer manner or a multilayer manner according to function requirements, different materials can be selected to manufacture the hollow balls with different mechanical properties, and the designability of the closed spherical anti-explosion container is high.

Description

technical field [0001] The invention belongs to the field of explosion-proof containers, and relates to a spherical explosion-proof container, in particular to a hollow spherical filled airtight spherical explosion-proof container. Background technique [0002] Explosion-proof container is a device that can weaken the lethal effect of shock waves and fragments produced by explosives on the surrounding environment. It is a special container for temporary storage or transfer of suspected explosives. It is suitable for public places or important facilities. The industry standard requires that when a certain equivalent of TNT explosive is detonated in an explosion-proof container, the container is allowed to deform, but no cracks, perforations or even tears can appear on the outer surface, and the surrounding environment of the container must not appear burning, dense smoke, dust, etc. With the advancement of technology, explosion-proof containers are developing in the direction...

AI Technical Summary

Problems solved by technology

The bulky structure makes installation and transportation inconvenient and expensive. When the tank explodes, high-temperature gas or debris may burst out from the pressure relief hole and cause secondary damage to the surrounding environment.
