Abstract
The invention discloses a lightweight opening density gradient metal foam explosion-proof tank device, which comprises an external tank body, an internal tank body and a buffer layer which is fixed between the external tank body and the internal tank body; the buffer body consists of metal foam which is changed along with a density gradient; and explosion-discharging holes with the same diameter are uniformly formed on the internal tank body. The setting of the explosion-discharging holes can obviously reduce the weight of the explosion-proof tank device and the damage of explosion wave to the internal tank body; the density gradient metal foam sandwich buffer layer is deformed through plastic compression so as to absorb the impact energy of explosion. The edge effect of the explosion-discharge holes changes the movement direction of explosive debris, reduces the speed of the explosive debris which moves at high speed; the foam metal can further reduce the speed of the debris and reduce the threat to protected personnel and buildings. The novel explosion-proof tank has the advantages of light weight, simple structure, low cost and strong reusability.
Description
Technical field
The invention belongs to anti-explosion tank device field, particularly a kind of lightweight opening density graded metal foam core anti-explosion tank device.
Background technology
Anti-explosion tank be a kind of shock wave that explosive produces and fragment of can suppressing to the lethal effect that surrounding environment causes, be used for depositing or the canned special-purpose harness of transport of detonation thing and other suspicious explosive temporarily.Industry standard requires after the TNT explosive of certain equivalent is ignited in anti-explosion tank, and tank body allows to deform, but phenomenons such as crack, perforation can not appear in outer surface, and phenomenons such as burning, dense smoke, dust must not appear in a jar interior attachment.According to actual needs, designed multiple anti-explosion tank.And anti-explosion tank of new generation just develops towards the direction of lightweight, multifunction and high performance.In recent years, along with technology of preparing improves, be that the appearance of the ultra light porous metal of architectural feature has realized structural material lightweight multifunction, thereby new selection be provided for the design of anti-explosion tank with millimeter level gap structure.
Summary of the invention
The object of the present invention is to provide a kind of lightweight opening density graded metal foam core anti-explosion tank device; Can significantly reduce the weight of anti-explosion tank; And can effectively resist the destruction that opposing explosion wave and explosive fragment bring out, have the dual-use function of resisting blast fragment and shock wave.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of lightweight opening density graded metal foam core anti-explosion tank device comprises outer tank body, interior tank body and the cushion between tank body and the interior tank body outside, in said, evenly offers the identical venting of dust explosion hole of diameter on the tank body, at the bottom of being provided with jar.
The shape of cross section in said venting of dust explosion hole is circle, ellipse, triangle or polygon.
The material of said outer tank body and interior tank body is respectively high strength steel, high-strength aluminum alloy.
The said jar of end is high strength steel, high-strength aluminum alloy.
The material of said cushion is metal foam.
Said metal foam is foamed aluminium, foam aluminium alloy, foam copper or blister steel.
Said cushion is density gradient to be changed, and radially adopts from inside to outside along tank body to set gradually high desnity metal froth bed, middle density metal froth bed and Low Density Metal Foam layer from inside to outside.
The material of said outer tank body and interior tank body is identical or different.
The thickness of said outer tank body and interior tank body is identical or different.
The present invention compares with prior art, has following advantage:
1,, thereby reduced the weight of anti-explosion tank device of the present invention owing on interior metal can, evenly offer the venting of dust explosion hole of certain density and certain size.
2, the venting of dust explosion hole can reduce the internal tank skin pressure of explosion wave, makes cushion metal foam generation plastic compression deformation, absorbs the blast impulse energy, thereby lowers the blast pressure that interior tank body bears, and has improved the explosion-proof impact capacity of interior tank body.Density gradient metal foam cushion has increased the path of shock motion, has reduced the surge of decling phase, has prolonged the action time of shock wave, makes cushion can fully absorb the blast impulse energy.Change the direction of motion of explosive fragment through the edge effect in hole; Reduce the speed of high-speed motion explosive fragment; Fragment is ruptured, become the slower fragment of some movement velocitys, and the density gradient foam metal can further reduce the speed of fragment; Even fragment motion is stopped, thereby can effectively reduce or eliminate explosion wave and fragment to being protected main body and personnel's thereof threat.
Therefore; Opening density graded metal foam core anti-explosion tank device of the present invention can reduce the weight of anti-explosion tank device significantly; It can resist the threat of explosion wave effectively when can effectively resisting the explosive fragment, has the double protection function of resisting explosive fragment and shock wave.That this anti-explosion tank has is simple in structure, the antiknock ability is strong, pollution-free, reusability is strong, low cost of manufacture, materials used have advantages such as recuperability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is done further explain.
As shown in Figure 1; A kind of lightweight opening density of the present invention graded metal foam core anti-explosion tank device; Comprise the cushion between outer tank body 1, interior tank body 2 and outer tank body 1 and the interior tank body 2, in said, evenly offer the identical venting of dust explosion hole 6 of diameter on the tank body 2, at the bottom of being provided with jar 7.
The shape of cross section in said venting of dust explosion hole 6 can have any shape, and is as shown in Figure 1 like circular, ellipse, triangle or polygon, is preferably circle, is convenient to processing.
The material of said outer tank body 1 and interior tank body 2 is respectively high strength steel, high-strength aluminum alloy.
