Description
Technical field
The utility model relates to a kind of protective device, relates in particular to a kind of for explosive element test and the protective device of testing.
Background technology
In explosive element high temperature accelerated aging test process, temperature, humidity have very important impact to accelerating ageing properties and the ager process of explosive element.Yet likely there is the danger of burning or blast in explosive element, brings difficulty to test and test with this understanding.For guaranteeing test, test safety, reduce the harm to equipment, facility, shielding container must be adopted, and following three basic functions must be realized:
1) have safeguard function: test is also online while detecting explosive element performance, if burning or blast occur explosive element, protective device must not through-wall crack, must not have fragmentation the fly out equipment of injuring, facility and people is worked the mischief.
2) there is cross-ventilation function: should be in the test period of regulation, the composition of shielding container inner air and outer air, temperature, humidity are consistent;
3) there is the passage that can detect explosive element performance.
By patent retrieval, the utility model patent of current published anti-explosion box body (comprising casing part) is 2,2 of utility model patents, 1 of design patent.But all patents for object be all the protection after explosive and electric accidental explosion, do not have and detect and test function.By inquiry " protective device " keyword, 68 of the patents that obtains having authorized.But major part is the explosion-proof of the processing manufacturing industries such as civil electric appliance and chemical industry, machinery, the blast causing such as high pressure, short circuit etc., the accident that cannot the be applied to priming system protection of detonating.Part utility model has been considered the protection of priming system, but the protection while also not relating to explosive test and online detection, be all the passive protection after accidental explosion, therefore do not consider to detect and guarantee in design the structure of circulation of air, also cannot be applied in the detection test of explosive element.
By literature survey, in the paper of publishing, explosion protection device is mainly the protection of household electrical appliance accidental explosion, high pressure scrubber for example, and pressure cooker and explosion-proof lamp, inconsistent with the purpose of this utility model.And the explosion-protection equipment of the chemical explosion relevant with explosive element design paper relates generally to the storing containers design of explosive, the for example antiknock device design of explosive storage box design > > and the anti-attack of terrorism for < < mine, for example < < airline carriers of passengers explosion-proof tank design > >.But the protection after blast is also only considered in these designs, and for explosive dose bigger than normal, therefore quality volume is larger, and be not suitable for test and the measuring ability of little dose for explosive element research.
Investigate and find, the protective device of published explosive element test or test use generally only has safeguard function, mostly is metal material, and quality is large, and equal protective capacities lower volume is also large, and inconvenient operation cannot be applied in the test detection of explosive element.At present, be badly in need of a kind of protective device, to realize above-mentioned three basic functions of shielding container, accomplish that volume is little, protective capacities is strong, easy to operate simultaneously.
