Abstract
The utility model relates to a laboratory equipment especially relates to a laboratory fume chamber. At present, most of the ventilation cabinets adopted in laboratories are of an upper opening type and a direct discharging type, and the purposes of ventilation and air exchange cannot be achieved for toxic and harmful gases with specific gravity larger than air. The utility model discloses it is two-layer to go up, down, and the upper strata is including can sealing laboratory bench 13 and ventiduct 14, and the lower floor includes the experiment cabinet. The air duct 14 is provided with an upper air outlet 12 and a lower air outlet 3. During actual operation, gas with specific gravity larger than that of air is easy to settle near the experiment table surface and can enter the air duct through the lower air outlet to be discharged. The utility model discloses mainly use as laboratory ventilation unit.
Description
The utility model relates to a kind of laboratory equipment, particularly relates to a kind of laboratory hood.
The vent cabinet of laboratory using mostly is to go up uncovered, straight-line at present, for the toxic and harmful of proportion greater than air, can't reach the purpose of ventilation, brings hidden danger for laboratory safety and experimenter's personal safety.
The purpose of this utility model is to provide a kind of vent cabinet that still can play the good ventilation ventilation effect for proportion greater than the toxic and harmful of air.
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is the front view of the utility model vent cabinet.
Fig. 2 is the side view of the utility model vent cabinet.
The utility model divides upper and lower two-layer, but the upper strata comprises enclosed experiment platform 13 and ventilating duct 14, lower floor Comprise experiment cabinet. But by the rear portion at enclosed experiment platform 13 vertical clapboard is installed, ventilating duct 14 is from ventilating The top of cabinet extends to the experiment table top, and opens exhaust outlet 12 at the vent cabinet top, at close experiment table top The position open exhaust outlet 3. During practical operation, most of gas can be from upper exhaust outlet 12 in the experimental bench Discharge; Proportion near the experiment table top, can enter ventilation greater than the gas free settling of air through lower exhaust outlet 3 Discharge in road 14.
The ventilating duct that is used for providing the aerofoil fan of ventilation power to be installed in the top also can be at the experimental bench rear portion Ventilating duct in install additional, the quantity of aerofoil fan is not limit.
The experimental bench side installs an air-conditioner 6, can control the experimental situation temperature, is suitable for experimental situation temperature requirement strict process process; Gas analysis alarm instrument 1 and warm, wetness display unit 5 are installed in top, can monitor experimental situation.
Place of windowing 15, vent cabinet front and the side place 16 of windowing, it is plug-type to make closed, outstanding window formula, flat-open type or the left and right sides according to specific requirement.Long-armed rubber gloves 2 also can be installed in the window bottom at the place of windowing, front 15, so that the experimenter is at the enterprising line operate of enclosed experiment platform.
The framework of vent cabinet is all made by the PVC material, has good closure, and corrosion-resistant, easy cleaning, long service life.Upper and lower water pipe 11 and fluorescent tube 9 also are installed in the vent cabinet.
The utility model can contrast great toxic and harmful in air and play good discharge effect, and has multiple function.
Embodiment
As depicted in figs. 1 and 2, vent cabinet divides upper and lower two-layer, but the upper strata comprises enclosed experiment platform 13 and ventilating duct 14, and lower floor comprises experiment cabinet.Ventilating duct 14 has exhaust outlet 12 and following exhaust outlet 3.Top axle flow fan 4 and rear axle flow fan 10 are housed respectively in the ventilating duct at top and experimental bench rear portion.Vent cabinet top is equipped with gas analysis alarm instrument 1 and warm, wetness display unit 5.Window and locate the outstanding window formula window of 15 employings in the front, the window bottom is equipped with long-armed rubber gloves 2.Window and locate the closed window of 16 employings in the side.But enclosed experiment platform 13 sides are equipped with air-conditioning 6, and power board 7 is placed in the drawer of vent cabinet lower floor.The experiment cabinet left side is a left and right sides sliding glass door cabinet 17, and the right is a vertical hinged door storage cabinet 8.Fluorescent tube 9 and upper and lower water pipe 11 also are housed in the vent cabinet.
