A fully sealed composite anti-explosion container

Abstract

The invention discloses an anti-explosion container of fully sealed composite material, which comprises an end cover assembly and a container main body. The end cover assembly and the container main body are meshed and connected through a multi-tooth structure. A high-density foamed aluminum layer, a partition, a low-density foamed aluminum layer and a spherical film are arranged in the stainless steel sheath from bottom to top; the main body of the container includes an outer layer of composite material, and the inner layer of the outer layer of composite material is A metal inner cylinder, the upper part of the metal inner cylinder is provided with an annular foamed aluminum layer, and the bottom of the annular foamed aluminum layer is provided with a partition layer. The anti-explosion container of a fully sealed composite material provided by the invention adopts carbon fiber reinforced epoxy resin-based composite material to wrap the cylinder body, and has high structural strength and light weight. The anti-explosion container of the present invention has the advantages of simple structure, fast opening and closing, reliable sealing, no fire-spraying phenomenon during explosion, low overpressure within a radius of 30cm of the mouth, which is less than the threshold value of 20kPa that can be tolerated by the human body; light in weight, and can be easily carried by one person.

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.
