Abstract
The utility model relates to an anti-explosion device, and in particular relates to a vacuum anti-explosion isolation device; the vacuum anti-explosion isolation device is provided with an interlayer which is internally filled with at least two vacuum bodies, each vacuum body comprises a shell, and a cavity for presetting vacuum is arranged in the shell. The vacuum anti-explosion isolation device fully utilizes the principle that vacuum adsorbs impact waves to absorb impact wave energy emitted by explosion in a multi-azimuth and multi-angle manner, so as to effectively reduce explosion power and reduce damage caused by explosion.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment, relates in particular to the anti-deflation isolator of a kind of vacuum.
Background technology
Be the considerable damage that prevents that explosion wave from causing, usually explosion-protection equipment need be set at some special occasions.Existing explosion-protection equipment generally is that employing has good mechanical properties, the anti-powerful material that impacts is processed, but this material cost is higher, and the explosion-protection equipment price of processing is more expensive, and the receptivity of this kind explosion-protection equipment shock wave is limited, and explosion-proof effect is not good.Some vacuum explosion-protection equipments are also arranged at present, but these devices are to utilize the vacuum principle to isolate oxygen basically, prevent on fire, burning and blast in the effective range.Because the explosion-proof area of these explosion-protection equipments must airtight vacuumizing, so the enforcement field is very limited, can't in daily life and physical environment, be used widely.And,, will cause heavy losses to resident's lives and properties if there is not explosion precaution fully in daily life because of electricity consumption, the blast that causes with the gas misoperation happen occasionally.
Summary of the invention
For addressing the above problem, the utility model provides a kind of anti-deflation isolator of vacuum with better explosion-proof effect.
For achieving the above object, the technical scheme that the utility model adopts is following: a kind of vacuum is prevented deflation isolator, and this device is provided with interlayer, is filled with at least two vacuum bodies in the said interlayer, and said vacuum body comprises housing, is provided with the cavity of preset vacuum in the housing.Be filled with some granular vacuum bodies in the interlayer in device; Owing to be vacuum state in the vacuum body, when the shock wave wave head that sends when blast arrived this device, vacuum body bore pressure and breaks; Moment of breaking utilizes the vacuum principle with shock wave wave head energy absorption; Some vacuum body actings in conjunction can absorb the shock wave energy of all directions, thereby significantly reduce even eliminate brisance.Because the internally provided with vacuum body has good explosion-proof effect, therefore can suitably reduce the thickness of explosion-protection equipment cladding material, practice thrift manufacturing cost.
The used vacuum body of the utility model needs processing in advance, fills it in the interlayer then.The housing of vacuum body is processed by the material with certain physical strength and is hermetically-sealed construction.Being vacuum state in the housing for making, can be machine-shaping under vacuum condition, also can vacuumize after the machine-shaping, then sealing again.
Above-mentioned housing can have certain physical strength and the material that can seal is processed by any, and is preferred, and said housing is processed by glass or resin or engineering plastics.
The described anti-deflation isolator of the utility model can be processed arbitrary shape as required; This device can be bursting diaphragm, explosion-proof quilt, explosion door, blast wall or explosion-proof tank; Can be in the tank wall of explosion-proof tank, to establish interlayer filled vacuum body when manufacturing explosion-proof tank; Also can be filled vacuum body in the explosion-proof tank of explosives is housed, all can play explosion-proof isolation effect.
The utility model has made full use of the principle of vacuum absorption shock wave, and multi-faceted multi-angle absorbs the shock wave energy that blast is sent, and effectively reduces brisance, has reduced the destruction that blast is brought.
