Rigid-flex composite explosion-proof tank

Abstract

The invention provides a rigid-flexible composite explosion-proof tank, which has the characteristics of strong explosion-proof ability and high safety factor; and can suppress flames and avoid flame leakage during explosions. Including: top cover, outer shell, interlayer filling body, inner shell, bottom energy-absorbing layer, bottom filling body, bottom buffer layer and bottom support; the outer shell is a cylindrical structure with openings at both ends, and the inner shell is an opening at the top. The cylindrical structure with the bottom closed by a hemispherical shell; the outer shell is coaxially sleeved outside the inner shell, and the bottom is connected to the spherical surface supported by the bottom; the interlayer filler is filled in the space between the outer shell and the cylindrical section of the inner shell In the annular interlayer; the top cover is used to close the top opening of the outer shell; the bottom energy-absorbing layer is arranged at the junction of the cylindrical section and the hemispherical section inside the inner shell; the space enclosed by the bottom energy-absorbing layer and the hemispherical section of the inner shell The bottom filling body is filled inside; the bottom buffer layer is arranged inside the outer shell, in the space enclosed by the outer shell, the hemispherical section of the inner shell and the bottom support.

Description

technical field [0001] The invention relates to an explosion-proof tank, in particular to a rigid-flexible composite explosion-proof tank, which belongs to the technical field of protective equipment. Background technique [0002] Explosion is a process of high-speed energy release, which requires extremely high protection for explosion-proof equipment. The general principles of current explosion-proof equipment mainly include energy-absorbing type, blocking type and composite type. [0003] Energy-absorbing explosion-proof: The explosion-proof structure based on the principle of energy-absorbing explosion-proof is generally composed of composite materials, aluminum foam, liquid and other deformable materials. After the explosion, the material itself undergoes large deformation or changes in phase state to convert the explosion hazard into Harmless kinetic energy, to achieve the effect of protection. Its advantages are light weight and low secondary damage; the disadvantag...

AI Technical Summary

Problems solved by technology

Its advantage is that there is no splash, and it can completely block the explosives in one place; the disadvantage is that it is generally heavy, and there may be secondary damage under excessive explosion conditions

A typical structure, such as that proposed by ZL 201810815781.8, adopts a toothed structure, the inner layer is made of high-strength steel, and the outer layer is wound with fiber materials. The top of this scheme is filled with a multi-layer foamed aluminum structure that can have a good energy absorption effect. After the explosion, the top cover is not easy to open, because the shock wave compresses the foamed aluminum and squeezes the side wall, which is prone to lockup

In addition, since it does not have a flame suppression structure, there will be flame leakage at the moment of explosion.
