Description
Technical field
The utility model relates to a kind of efficient vent cabinets of new type of safe, belong to vent cabinet technical field.
Background technique
Vent cabinet is equipment general in laboratory, and for the pretreatment of sample before testing, toxic, volatile reagent is matched
Setting need to carry out in vent cabinet.Laboratory sample is cleared up on electric hot plate with nitric acid, hydrochloric acid, hydrofluoric acid and perchloric acid etc.,
Generate that corrosivity is toxic, pernicious gas.Therefore the vent cabinet of in-built electrical hot plate must have good ventilation, heat insulation and side
Just observation and operation.Currently used vent cabinet, the cabinet door pushed and pulled including cabinet body and up and down, cabinet door generally use silica glass door.
Existing vent cabinet has the disadvantage that
First, vent cabinet in the case where power of fan is certain, after cabinet door is opened, open bigger, and wind speed is then slower by cabinet door,
Cause that toxic, pernicious gas pump drainage is not thorough enough, operator's observation or when picking and placing the sample of inside on electric hot plate is often passive
Suck toxic, pernicious gas；
Second, carry out experimental implementation when, electric hot plate exposed area is larger, operator by high-temperature baking, it is scorching hot feel bad,
Even cause skin scald；
Third when operator operates, is fully exposed to by electric hot plate above the waist, when with heating board digestion sample,
Due to temperature height, phenomenon is often splashed, it is careless slightly, gently then burn out clothes, heavy then skin burn；
4th, hydrofluoric acid has strong corrosiveness to silica glass, and silica glass will soon be etched into as translucent mill
Sand glass shape influences operator and observes state in cabinet.
Utility model content
Purpose of the utility model is to solve the above-mentioned problems of the prior art, and then provide a kind of new type of safe
Efficient vent cabinet.
The purpose of this utility model is achieved through the following technical solutions:
A kind of efficient vent cabinet of new type of safe, including upper cabinet body and lower cabinet body, the lower cabinet body are provided with locker, storage
It is provided with door handle on object cabinet, the upper cabinet body top is equipped with exhaust hood, action pane is equipped among upper cabinet body, in action pane
Equipped with operating table surface, left side plate and back side panel, the bottom of upper cabinet body is arranged in operating table surface, respectively with left side plate, rear side
The bottom end of plate connects, and operating table surface is equipped with gas gathering mask, and left inside lining, right liner and rear liner, rear liner point are equipped in gas gathering mask
It is not connect with the bottom end of left inside lining, right liner, the upper end of gas gathering mask is provided with gas gathering mask upper cover, and gas gathering mask upper cover passes through air-exhausting duct
It is connected to exhaust hood.
The gas gathering mask is rectangular, rectangle or trapezoidal, and material is PP plate.
The left inside lining, right liner and rear liner material be ultra-fine asbestos board, the ultra-fine asbestos board with a thickness of
2mm。
The size of the gas gathering mask is 800mm*600mm*800mm, or can adjust size according to the actual situation.
The gas gathering mask is detachable gas gathering mask.
Power outlet and control panel are respectively arranged on the left side plate.
The utility model has the following beneficial effects:
First, in use, electric hot plate and sample pass through the action pane of gas gathering mask in gas gathering mask to vent cabinet
Sample is observed and picked and placed, in the case where total exhaust air rate is constant, since the area of operation window is small, substantially increases air draft wind
Speed, thus solve the problems, such as resolution sample in it is toxic, pernicious gas pump drainage is halfway, so that operator be made to observe
Or toxic, pernicious gas will not be sucked when picking and placing the sample for being especially inside on electric hot plate.
Second, because electric hot plate is all covered by gas gathering mask, the thermal Finite radiated by operation window reduces experiment behaviour
The radiant heat for making personnel's receiving reduces burning heat sensation.And gas gathering mask liner is ultra-fine asbestos board, and heat insulation is preferable, can reduce
The heat radiation that operator receives.
Third, existing vent cabinet in use, when with heating board digestion sample, due to temperature height, Specimen eliminating
Often phenomenon is splashed.And the vent cabinet of the utility model, when Specimen eliminating, carry out in gas gathering mask, operator can basis
It needs to shelter from operation window using baffle, realization operator is isolated with sample, reduces security risk.
4th, the cabinet door of existing vent cabinet relatively mostly uses silica glass, and hydrofluoric acid has strong corrosiveness to silica glass,
Glass door will soon be etched into as ground glass shape, influence experimenter and observe state in cabinet, and the replacement of its cabinet door is got up
It is pretty troublesome, cost is also high.The vent cabinet of the utility model cancels the cabinet door pushed and pulled up and down, solves the above problem, reduces
Cost.
