Unload and be connected with blast pipe, blast pipe is provided with air extractor, and the outlet side of blast pipe, which is connected with filtering flask, filtering flask, to be loaded with
Pernicious gas filtered fluid, the outlet side of blast pipe is extend under the liquid level of pernicious gas filtered fluid, and the bottle mouth position of filtering flask is provided with
Stopper, filtering flask top is provided with gas outlet, gas outlet provided with filtering tampon；The inwall of protective cover is provided with overcoat, overcoat
It is made with operation gloves by chlorosulfonated polyethylene material；The top of protective cover, which is provided with circular hole, circular hole, is provided with block head.
Air extractor is air exhauster.
The bottom sides of protective cover are the open minor arc knot in bottom along the cross sectional shape provided with overall sucker in a ring, sucker
Structure.
Using above-mentioned technical proposal, carry out initially, the present apparatus being located on laboratory apparatus, makes experiment instrument in chemical experiment
Device is located inside device, then starts chemical reaction, has the splash out of instrument of the liquid of epistasis to go out in chemical reaction,
Protective cover and experimenter will not be caused harm, therefore the protective cover protects the safety of experimenter well, works as experiment
When producing pernicious gas, only it need to contain corresponding absorbing material in filtering flask, air extractor will be produced in protective cover
Pernicious gas is pumped into filtering flask, is absorbed；In addition in experimentation, if necessary to adding the chemistry such as catalyst in instrument
During medicine, block head only need to be extracted, medicine is added dropwise using instrument of the dropper into protective cover；Glass is provided with front side of protective cover
Observation window, the observation experiment that operating personnel can be safe before glass window；Overcoat and operation gloves are poly- by chlorosulfonation
Vinyl material is made, due to the acid-fast alkali-proof characteristic of chlorosulfonated polyethylene material, so overcoat and operation gloves can be abundant
Ensure the use of protective cover and the safety of operating personnel；Filtering flask top is provided with gas outlet, gas outlet provided with filtering tampon,
Secondary filter can be carried out to the pernicious gas in filtering flask by filtering tampon, and the innocuous gas after filtering is outside at gas outlet again
Discharge；Protective cover can be firmly adsorbed on experimental bench by the bottom sides of protective cover along sucker, sucker is provided with, while will protection
Sealed between the bottom surface of cover and experiment table top, prevent pernicious gas from exposing from gap；Blast pipe and exhaust fitting
It is detachably connected, so split type connection is easy to carry the mobile present apparatus；
In summary, the utility model is simple in construction, easy to operate, can safely carry out chemical experiment, for experiment people
Member provides safety guarantee.
