Background technology
Intercept explosion-proof technology and be extended to the feasibility technology that prevents the oil product blast safely and effectively by country, facts have proved that it has remarkable result aspect safety in production and the environmental protection.With reticulated aluminum alloy explosion-proof lamp container is divided into many very little unit, the multi-layer silk screen structure can be torn into countless little flame groups to the flame group that therefrom passes through, thereby prevent flame transmission, simultaneously, mesh structural porous structure can be carried out interchange of heat rapidly, and heat is disperseed fast or absorbs, reduced the final temperature after the combustion reaction, dwindle the degrees of expansion of reacting gas, thereby made the limit of force value out of reach explosion, prevented the generation of exploding.At present block blast-proof materials often is prone to structural distortion, the breakage of caving in, falls defectives such as bits and service life is short, and these defectives might cause dangerous generation such as fuel oil and imflammable gas detonation.
The utility model content
The utility model provides the cellular aluminum alloy of a kind of 3 D stereo to intercept burst disk, to overcome the drawback that prior art exists.
For realizing the utility model purpose, it is aluminum alloy sheet that the cellular aluminum alloy of this 3 D stereo intercepts its main body of burst disk, it is characterized in that the staggered long joint-cutting of 0.8~1.2cm that evenly offers on the aluminum alloy sheet, make aluminum alloy sheet form three-dimensional honeycomb net structure along joint-cutting vertical direction stretching aluminum alloy sheet.
The cancellated honeycomb hole of described honeycomb is hexagonal hole.
Described aluminum alloy sheet thickness is 0.08~0.15mm.
The utility model takes tensile strength greater than the high-strength aluminium lithium alloy of 480MPa, and aluminum lithium alloy can reduce the proportion of alloy and increase rigidity, can still keep simultaneously higher intensity, resistance to corrosion and fatigue resistance and suitable ductility preferably.
The utility model is by adopting the high strength aluminum alloy material, the aluminum alloy that forms the 3 D stereo cellular structure intercepts burst disk and has higher intensity and resistance to corrosion preferably, heat conductivility is strong, ductility is good, good toughness, be not prone to structural distortion, the breakage of caving in, fall phenomenons such as bits, and have advantages such as long service life.Can be widely used in the fuel transport car, fuel tank such as the filling car that flows, aircraft gas refueller, military-designed vehicle, aircraft, naval vessels and oil tank be explosion-proof; Also can be used for the explosion-proof of containers such as various storage gasoline, diesel oil, dimethylbenzene, acetone and tank body, can effectively restrain dangerous generation such as gasoline, methane, propane, diesel oil, acetone, toluene, ethane, oil equal solvent and the detonation of similar effumability combustible, can effectively eliminate static, when container leakage of the present utility model is housed, can directly under band oil or band gas mode, use or carry out electric welding; In transportation, can reduce the shaking degree of oil plant liquid being equiped with truck tanker of the present utility model, and the container inner wall that do not wear and tear does not pollute oil, and is indeformable in container, not not loss of burn in the oil plant equal solvent, not broken, do not stop up oil circuit, once pack into and can use for a long time.After in oil tank, installing the lumps burst disk of the utility model structure, when accidents such as chance naked light, static, welding, gunslinging, thunderbolt, collision and maloperation, can not blast, even if presence of fire, also can slow down owing to obstruct of the present utility model makes the flame burning propagation speed, and can obviously reduce flame height, be conducive to fire extinguishing, have good explosion-proof and datonation-inhibition function.
The specific embodiment
As shown in Figure 1, it is 0.08~0.15mm that the cellular aluminum alloy of this 3 D stereo intercepts explosion-proof aluminum alloy sheet 1 thickness, at this aluminum alloy sheet 1 staggered joint-cutting 2 of evenly offering 0.8~1.2cm, the distance that each joint-cutting is 2 is identical, make it to form 3 D stereo honeycomb net structure as shown in Figure 2 behind the joint-cutting 2 vertical direction stretching aluminum alloy sheets 1, the cancellated honeycomb hole 3 of honeycomb is hexagonal hole.
The utility model manufacture craft is by cutting after machine drawing carries out raphe transection with high-strength aluminium lithium alloy sheet 1, longitudinal stretching is extended to 3 D stereo honeycomb net structure again, makes stretching be extended to the cancellated the utility model of 3 D stereo honeycomb by folding or coiling then and forms three-dimensional lumps.After being loaded into it in inflammable and explosive gas (liquid) body storage-transport vessel, it will be separated into many small cell cubes in the container, these small cell cubes run into naked light, static, welding, gunslinging, thunderbolt, collision and maloperation etc. when unexpected at container, the heat absorption that the thermal diffusivity that it has can discharge burning rapidly, final combustion temperature is reduced greatly, the degrees of expansion of gas is dwindled, thereby reaches explosion-proof, datonation-inhibition effect.
