Description
Technical field
The utility model relates to experimental assembly and makes field, relates in particular to a kind of vent cabinet.
Background technology
The vent cabinet of prior art generally all adopts blower fan to force the toxic gas in inner chamber to detach, but toxic gas the experimental difference of flux and different, the blower fan of prior art is generally all set to unified power and cannot changes and change along with toxic gas, when toxic gas is few, can waste energy consumption, when toxic gas is many, cannot effectively get rid of again, be further improved.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of and can automatically regulate exhaust air rate, and air draft is effective, the air-volume-variable fume hood that automaticity is high.
For realizing the utility model object, provide following technical scheme: a kind of air-volume-variable fume hood, comprise cabinet, cabinet is comprised of the workbench on top and the brace table of bottom, described workbench comprises internal-response chamber, workbench front window and bench-top exhaust outlet, in described reaction chamber, be provided with successively three deflectors of upper, middle and lower, the upper and lower two ends of front window are provided with rail plate, three fan implosion guard doors are installed on described guide rail side by side, two ends, front window left and right are arranged at sealing joint strip, described exhaust outlet connects exhaust duct, exhaust duct connecting fan, on described exhaust duct, be provided with duct static pressure sensor, micro-anemobiagraph, variable air rate control valve, on the cabinet wall of workbench left side, be provided with control panel, display screen and intelligent chip are set in described control panel, described duct static pressure sensor, micro-anemobiagraph, variable air rate control valve is all connected with intelligent chip signal, described blower fan is electrically connected to frequency converter, frequency converter is connected with intelligent chip signal.By above-mentioned setting, set up deflector and automatic control system, greatly simplify mode of operation and improved air draft effect.
As preferably, described blower fan is connected by the signal of telecommunication with described intelligent chip, in described exhaust duct, be provided with air purifier, described intelligent chip connects can be by wireless signal transmission to the wireless signal transmitting device on mobile device, described exhaust duct outside is provided with air monitor, and described air monitor is connected by the signal of telecommunication with intelligent chip.
As preferably, bench-top exhaust outlet is set at least one.
As preferably, cabinet is composite plate.
As preferably, described composite plate outward in be followed successively by kapok layer, adhesion coating, glass layer and flame-retardant layer.
The beneficial effects of the utility model: the utility model noise is little, and automaticity is high, and air draft is effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
