The specific embodiment:
In conjunction with accompanying drawing 1 and embodiment the gas exposure cabin antiknock safe shielding apparatus of this utility model is explained.
The structure of the gas exposure cabin antiknock safe shielding apparatus of this utility model comprises an airtight shielding cabinet 8; Make by metal material and special explosion-proof safety glass 5; When blast in inside; Explosion-proof safety glass 5 is not easy fragmentation when receiving external force or gas shock, be tiny obtuse angle state when broken, can not damage human body.Airtight shielding cabinet 8 inside comprise a gas exposure cabin 7; The middle part in gas exposure cabin 7 is a cylinder; It is the main part in gas exposure cabin 7; Explosive-proof sealed door is installed at cylinder middle part, its with gas exposure cabin 7 between have sealing joint strip to seal, guaranteed the sealing in gas exposure cabin 7.Highly on the movable top cover 1 above explosion-proof division board top, operator's airtight shielding cabinet 8 tops a plurality of two-way valve gaps 2 of releasing of explosion that have self-locking are arranged; Can guarantee that airtight shielding cabinet 8 internal negative pressures are constant in 50Pa; If fire; Internal pressure makes the one-sided unlatching that makes progress automatically of the two-way valve gap 2 of releasing when airtight shielding cabinet 8 pressure inside surpass the predetermined safe ultimate value, discharges too high pressure, avoid to around explode and damage; When airtight shielding cabinet 8 internal pressures reduced, the two-way valve gap 2 automatic downward one-sided unlatchings of releasing let outside air flow to airtight shielding cabinet 8, kept inside and outside gas balance.There is a movable sealing door 6 that the quick handle 4 of dual fail-safe safety lock is installed in airtight shielding cabinet 8 fronts, and the sealing joint strip sealing is arranged between all the other airtight shielding cabinets 8, have guaranteed the seal of airtight shielding cabinet 8; The safety lock of the quick handle 4 of dual fail-safe safety lock guarantees the airtight of movable sealing door 6, prevents that experimental gas from leaking, in case when blasting, the locking of twice discharge cock prevents that movable sealing door 6 from being washed open by powerful stream pressure, injures operator.Airtight shielding cabinet 8 circuit external supervisory keyboards 3 can be in airtight shielding cabinet 8 outside remote control experiments; On circuit supervisory keyboard 3, experiment parameter is set; Parameter is used in all experiments like contamination time, concentration of contamination, flow, speed, temperature, humidity etc.; Be provided with to accomplish and confirm that experiment begins gas inside contamination cabin 7 and carries out the flammable explosive gas viral infection test; Control stops experiment on circuit supervisory keyboard 3 when blast takes place, and the power that reduces to explode is effectively protected operator.Gas exhaust piping 9 and discharge pipe line 11 are arranged at airtight shielding cabinet 8 bottoms, and the waste gas that gas exposure cabin 7 produces in the contamination process is discharged through gas exhaust piping 9 safety, cleans the waste water that produces behind the exposure experiment and emits through fluid discharge pipeline 11; The antiknock safety isolated gate 10 that gas exhaust pipings 9 that all are connected with the external world and drainage interface 11 inside all have damping action; When having airflow or current to discharge; Antiknock safety isolated gate 10 can in time close the loop circuit; Allow air-flow or current to discharge, prevent that air-flow or current from leaking fast, impacts with normal speed.
Embodiment:
At first laboratory animal is put in the gas exposure cabin 7 when using this utility model gas exposure cabin antiknock safe shielding apparatus; Close explosive-proof sealed door; And then close the movable sealing door 6 of airtight shielding cabinet 8, on circuit supervisory keyboard 3, set each experiment parameter, like contamination time, concentration of contamination, flow, speed, temperature, humidity etc.; Be provided with to accomplish and confirm the experiment beginning, the flammable explosive gas viral infection test is carried out in gas inside contamination cabin 7; Each parts of equipment all adopt explosion-proof component, and are airtight air tight, and whole system is equipped with good safety ground and antistatic surface, and the flames of anger does not have high-pressure electrostatic, so eliminated because the unsafe factor that system itself produces.If just in case there is blast to take place, in instant of detonation, the one-sided unlatching that makes progress automatically of the two-way valve gap 2 of releasing on the removable top cover 1 discharges too high pressure, avoid to around explode and damage; Stop experiment by the stop key on the volt circuit supervisory keyboard 3 immediately; The twice safety lock of the quick handle 4 of dual fail-safe safety lock on the movable sealing door 6 is locked immediately; Preventing that movable sealing door 6 from being impacted opens; The gas exhaust piping 9 of 7 bottoms, gas exposure cabin can in time close the loop circuit with discharge pipe line 11 inner antiknock safety isolated gates 10, prevents that air-flow or current from leaking fast, impacts; The capability of antidetonance of explosion-proof safety glass 5 has also increased another layer protection, has effectively protected operator's safety.
