Fully sealed composite explosion-proof container

Abstract

The invention discloses a fully sealed composite explosion-proof container comprising an end cover component and a container body. The end cover component is engaged and connected with the container body through a multi-tooth structure, and the end cover component comprises a cover plate of which the lower part is provided with a stainless steel jacket; the stainless steel jacket is internally provided with a high density aluminum foam layer, a separating plate, a low density aluminum foam layer and a spherical film from bottom to top in sequence; and the container body comprises a composite outer layer of which the interior is a metal inner barrel, and the upper part of the metal inner barrel is provided with an annular aluminum foam layer of which the bottom is provided with a separatingplate layer. According to the fully sealed composite explosion-proof container provided by the invention, the barrel is wound by carbon fiber reinforced epoxy resin matrix composites; and the structural strength is high, and the weight is light. The explosion-proof container has the advantages of the simple structure, quick opening and closure, reliable sealing and no fire phenomenon during explosion; the overpressure within the 30cm radius of the opening part is low, and less 20 kPa than the threshold that a human body can bear; and the explosion-proof container is light in weight, and can be handled by one person easily.

Description

technical field [0001] The invention relates to the technical field of anti-explosion containers, in particular to an anti-explosion container of fully sealed composite material. Background technique [0002] Anti-explosion containers can limit the scope of action of shock waves, detonation products and fragments generated by the explosion of explosives inside the container, effectively protect the safety of personnel, equipment and the environment. The safety field plays an important role and is a typical high-end explosion protection equipment. [0003] Most of the portable anti-explosion containers currently used are metal open anti-explosion containers. The open anti-explosion containers can effectively prevent the fragments and shock waves generated by the explosion from scattering and spreading laterally, and protect people and equipment beyond a certain distance from the side from being damaged. However, when it is used in airplanes, trains and other places with narr...

AI Technical Summary

Problems solved by technology

However, when it is used in airplanes, trains and other places with narrow space, limited height, and densely populated places, the explosion safety distance of the open anti-explosion container cannot be guaranteed; the open anti-explosion container cannot limit the fragments and shock waves generated by the explosion in the vertical direction spread, causing damage to the roof of the compartment

Therefore, the metal open anti-explosion container is not suitable for vehicles and indoor places, and it is necessary to design a sealed anti-explosion container to completely limit the internal explosion products and explosion shock waves to provide close-range and all-round protection for equipment and personnel.
