Description
Technical field
The present invention relates to a kind of use for laboratory equipment, relate in particular to a kind of vent cabinet of use for laboratory.
Background technology
Vent cabinet is a kind of local exhaust equipment conventional in laboratory, and vent cabinet can be discharged workplace completely, in time by pernicious gas, can prevent that operator from sucking gas poisonous, that be harmful to, have peculiar smell, plays a very good protection to operator.On vent cabinet, be conventionally provided with work top, operating personnel test on work top, and the blower fan on vent cabinet top is discharged pernicious gas.Existing vent cabinet is, at cabinet top, exhaust outlet is set, blower fan is installed at top, because exhaust outlet is larger from work top distance, if will pump pernicious gas completely, the wind speed of blower fan is larger, can make work top wind speed exceed standard, in addition, because gas molecule sharply moves up and down, can form turbulent flow, cause the wind speed of work top inhomogeneous, pernicious gas is absorbed not exclusively.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provide a kind of simple in structure, inlet scoop from work top close to, guarantee that work top wind speed is even, can absorb the vent cabinet of pernicious gas completely.
For achieving the above object, the technical solution used in the present invention is: a kind of ventilation hoods for laboratories, comprise cabinet, described cabinet is provided with blower fan in top, it is characterized in that: described cabinet comprises Over-The-Counter and have the lower cabinet of work top, each side of described Over-The-Counter and lower cabinet is connected by gripper shoe, is provided with the up-narrow and down-wide conical flow guiding pipe of lower cabinet described in subtend in described Over-The-Counter, the narrower one end of described mozzle is connected with netted laminate, between described laminate and blower fan, is provided with screen pack.
In a preferred embodiment of the present invention, further comprise that described gripper shoe is provided with tap, over against described faucet outlet, be provided with tank cashier's office in a shop under described.
In a preferred embodiment of the present invention, further comprise and on described laminate, be also provided with illuminating lamp and bactericidal lamp.
In a preferred embodiment of the present invention, further comprise on a pair of inwall being parallel to each other of described Over-The-Counter and be equipped with groove, described filter network card is located in described groove.
In a preferred embodiment of the present invention, further comprise that the air inlet place of described blower fan is also provided with the wind-collecting cover of " ︺ " shape.
In a preferred embodiment of the present invention, further comprise that the diameter of one end that described mozzle the is wider and length of described Over-The-Counter and width equates.
In a preferred embodiment of the present invention, further comprise that described bactericidal lamp is ultraviolet radiator.
In a preferred embodiment of the present invention, further comprise that described screen pack is activated charcoal strainer.
In a preferred embodiment of the present invention, further comprise that described blower fan is centrifugal blower.
The invention solves the defect existing in background technology, ventilation hoods for laboratories of the present invention, by up-narrow and down-wide conical flow guiding pipe is set in Over-The-Counter, can make pernicious gas in mozzle, be spiral, avoid pernicious gas sharply to move up and down, can not produce turbulent situation, can absorb pernicious gas completely, guarantee that work top wind speed is even.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
In figure: 10, Over-The-Counter, 12, work top, 13, lower cabinet, 14, gripper shoe, 15, groove, 16, exhaust outlet, 20, blower fan, 21, wind-collecting cover, 30, mozzle, 40, laminate, 50, screen pack, 60, tap, 70, tank, 80, illuminating lamp, 90, bactericidal lamp.
The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, a kind of ventilation hoods for laboratories, comprises cabinet, and cabinet comprises Over-The-Counter 11 and the lower cabinet 13 with work top 12, and Over-The-Counter 11 tops are provided with exhaust outlet 16, and Over-The-Counter 11 is interior is provided with blower fan 20 near exhaust outlet 16 places; Each side of Over-The-Counter 11 and lower cabinet 13 is connected by gripper shoe 14; In Over-The-Counter 11, be provided with the up-narrow and down-wide conical flow guiding pipe 30 to downward cabinet 13, the narrower one end of mozzle 30 is connected with netted laminate 40, the wider one end of mozzle 30 flushes with the lower end of Over-The-Counter 11, and the diameter of one end that mozzle 30 is wider equates with length and the width of Over-The-Counter 11; Between laminate 40 and blower fan 20, be provided with in screen pack 50(the present invention said upper and lower be according to cabinet under use state from exhaust outlet 16 direction of cabinet 13 down).In the present invention, up-narrow and down-wide conical flow guiding pipe 30 is set Over-The-Counter 11 is interior, blower fan 20 is when exhausting, the gas being gathered on work top 12 sucks through mozzle 30, in mozzle 30, pernicious gas is spiral, avoid pernicious gas sharply to move up and down, can not produce turbulent situation, can absorb pernicious gas completely; Pernicious gas spiral, can not produce convection current, guarantees that work top 12 wind speed are even; Because the lower end of mozzle 30 flushes with the lower end of Over-The-Counter 11, the lower cabinet 13 of distance is nearer, and the wind speed of blower fan 20, without excessive, guarantees that work top 12 wind speed are even.In addition, in the present invention, in Over-The-Counter 11, be also provided with screen pack 50, can carry out primary filter to pernicious gas, avoid direct discharge of noxious gases and contaminated air.
