Anti-fragment wave absorbing explosion removing tank

Abstract

The invention belongs to explosion removing devices and mainly relates to an anti-fragment wave absorbing explosion removing tank. The wall face of the explosion removing tank (1) sequentially comprises a decorating layer (6), a continuous basalt fiber layer (5), a steel plate (4), foamed aluminum (3) and a lining steel plate (2). The decorating layer (6) is located at the outermost layer, at least one layer of the continuous basalt fiber layer (5) is located on the outer layer of the steel plate (4) and mainly has the anti-fragment function, the foamed aluminum (3) is located between the steel plate (4) and the lining steel plate (2) and mainly has the wave absorbing function, and the feature that explosion shock wave energy can be effectively absorbed is utilized to reduce shock wave peak pressure and convert instant shock wave load into quasi-static load. The foamed aluminum (3) is made of at least one layer of single-specification materials, when the multiple layers of the foamed aluminum (3) are arranged according to anti-explosion requirements, the foamed aluminum layers are sequentially arranged with the density decreasing from outside to inside, and the foamed aluminum structure with certain density gradient is formed.

Description

technical field [0001] The invention belongs to anti-explosion equipment, and mainly relates to an anti-explosion tank with the functions of anti-fragmentation and shock wave reduction. The explosion-proof tank is manufactured by optimizing the combination of materials, which can effectively eliminate the fragmentation effect of the explosion and greatly reduce the shock wave effect of the explosion. While realizing the anti-fragment wave absorption performance, it can also effectively reduce the weight of the explosion-proof tank, improve the use function, and expand scope of use. Background technique [0002] Terrorist activities are becoming more and more rampant in today's world. Terrorists often carry out terrorist attacks by placing bombs in densely populated areas such as subways, airports, and urban areas. When the explosive explodes, it mainly produces the blast wave effect, but when the explosive is packed by hard materials such as metal, concrete, glass, wood, et...

AI Technical Summary

Problems solved by technology

Although the solid explosion-proof tank has high anti-explosion and anti-burst penetration capabilities, it has the disadvantages of heavy weight and inability to effectively reduce the blast shock wave load.

The multi-layer composite structure can greatly reduce the weight of the explosion-proof tank and realize the function of weakening the peak pressure of the shock wave, but its anti-explosion and anti-penetration capabilities are relatively weak
