Description
Technical field
This utility model relates to use for laboratory ventilation installation, particularly relates to a kind of fume hood.
Background technology
Laboratory ventilation is a very important part in laboratory design, and use for laboratory fume hood can be avoided testing people
Member sucks the chemical substance poisonous, toxicity is not clear and organism, the health of all personnel in battle support laboratory.Existing laboratory
Fume hood can to toxic gas from laboratory extract out, but can not active adsorption, some fume hoods are by laboratory
Gas extract out after after simple filtration, be just directly discharged to outdoor, not only pollute environment, also can endanger surrounding population
Health, and existing fume hood is cleared up and maintenance inconvenience, fume hood uses the time long, saves bit by bit more ash in ventilation shaft
Dirt, dust surface is often in contact with the chemical gas extracted out, and when not using fume hood, the chemical odor on dust surface can spill into
In laboratory, pollute indoor environment, cumbersome when the dust in ventilation shaft is cleared up, even need ventilation shaft
Remove and clear up, waste time and energy.In addition, the vent of the fume hood of use for laboratory can not collect to a great extent
Wind, convulsion effect is poor, needs to open a part of glass when testing and draws window, the bad meeting of convulsion effect to make toxic gas easy
Spread to laboratory internal, threaten to the safety of experimenter.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fume hood, this fume hood
Can more conveniently clear up the dust of ventilation shaft, collection wind is effective, and gas is not directly discharged to outdoor, it is to avoid pollute environment,
Ensure the health of people.
The technical solution of the utility model is achieved in that a kind of fume hood, including bookcase body, vent and ventilation duct
Road, described ventilation shaft is positioned at the top of bookcase body, and described ventilation shaft connects air-introduced machine, and described air-introduced machine is by pipe
Road is connected with dust cleaning case, and the top of described dust cleaning case is provided with spray head, and the described lower end in dust cleaning case is provided with drainage screen
I, the sidewall of described dust cleaning case is provided with a floss hole, at described floss hole, is provided with efficient active carbon filter；
Described ventilation shaft is internal with bookcase body to be connected by vent, is provided with drainage screen II and filter core at described vent.
Above-mentioned fume hood, is filled with high-efficiency multiple adsorbing material in described filter core.
Above-mentioned fume hood, is provided with wind-collecting cover at described vent.
Above-mentioned fume hood, described wind-collecting cover is threaded connection with vent outer wall.
Above-mentioned fume hood, described wind-collecting cover is movably installed with baffle plate.
Above-mentioned fume hood, described air-introduced machine connects stand-by power supply.
The beneficial effects of the utility model are: the utility model discloses a kind of fume hood, can more conveniently clear up logical
The dust of wind pipeline, collection wind is effective, still can use when having a power failure, and gas is not directly discharged to outdoor, it is to avoid pollute environment,
Ensure the health of people.

Fig. 1 is structural representation of the present utility model；
Fig. 2 is the enlarged drawing of dust cleaning case of the present utility model.
In figure: 1-bookcase body, 2-ventilation shaft, 3-vent, 4-wind-collecting cover, 5-drainage screen I；6-filter core, 7-baffle plate,
8-air-introduced machine, 9-drainage screen II, 10-dust cleaning case；11-spray head, 12-efficient active carbon filter, 13-exhaust outlet.
Detailed description of the invention
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings, in order to be better understood from this
New technique scheme.
Embodiment: fume hood, as depicted in figs. 1 and 2, including bookcase body 1, vent 3 and ventilation shaft 2, ventilation shaft 2
In the top of bookcase body 1, ventilation shaft 2 is internal with bookcase body 1 to be connected by vent 3, is provided with drainage screen I 5 and filters at vent 3
Filter element 6, is filled with high-efficiency multiple adsorbing material in filter core 6, it is possible to adsorb most toxic gas, and filters
Filter element 6 is positioned at vent 3, convenient dismounting and replacing filler.The end of vent 3 is provided with wind-collecting cover 4, wind-collecting cover 4
It is threaded connection with vent 3 outer wall, wind-collecting cover 4 is movably installed with baffle plate 7.Ventilation shaft 2 connects air-introduced machine 8, draws
Blower fan 8 connects stand-by power supply, makes air-introduced machine 8 still can run when having a power failure.Air-introduced machine 8 is by pipeline and dust cleaning case 10 phase
Even, the top of dust cleaning case 10 is provided with spray head 11, and the lower end in dust cleaning case 10 is provided with drainage screen II 9, on the sidewall of dust cleaning case 10
It is provided with a floss hole 13, at floss hole 13, is provided with efficient active carbon filter 12, make the gas emitted pollution-free, it is ensured that
The safety of surrounding people.When the air-introduced machine of fume hood is opened, in bookcase body, gas first passes through drainage screen I 5 and filter core 6, enters
The preliminary absorption of row, then into dust cleaning case 10, is discharged into outdoor after the adsorption filtration of efficient active carbon filter 12, logical
Dust in wind pipeline 2 pours at drainage screen II 9, in making ventilation shaft 2 with the water of spray head 11 ejection after entering dust cleaning case 10
Dust cleaning convenient, time saving and energy saving；After the air-introduced machine of fume hood cuts out, baffle plate 7 is installed to the port of wind-collecting cover 4,
Prevent the residual gas in ventilation shaft 2 from spilling in laboratory, pollute the air of laboratory.
