Abstract
The utility model discloses a ventilating cabinet, in particular to a ventilating cabinet of a laboratory. The ventilating cabinet of the laboratory is easier to exhaust the gas and the dust. The ventilating cabinet comprises a cabinet body, as well as an operating table, an air exhausting cover, an exhaust fan and an air pipe arranged in the cabinet body, wherein the air exhausting cover is connected with the exhaust fan by the air pipe, the air exhausting cover is arranged under the operating table, and the operating table is provided with a plurality of through holes which are communicated with the hollow cavity of the air exhausting cover. The air exhausting cover which is arranged at the back side of the operating table can exhaust the gas and the dust which are generated by a test from the operating table, so that the ventilating cabinet can avoid the problem that the dust can not be upwards exhausted caused by the dead weight, and can timely exhaust the generated gas from the lower part, without influencing operators who are higher than the operating table. The through holes also can be arranged at one side which is close to a back plate, so that the test is performed at the outer side of the operating table, the exhaust is performed at the inner side of the operating table, and the test and the exhaust are not interfered with each other. The through holes can be evenly arranged, thus keeping the inner part of the cabinet body to be clean.
Description
Technical field
The utility model relates to a kind of laboratory hood, and is especially a kind of at the easy laboratory hood that uses in the experiment of dust that produces.
Background technology
In experiment, produce some toxic gases and dust, at this moment just need the operation that experimentizes of special laboratory hood through regular meeting.Its draught hood of traditional laboratory hood is arranged on the top position of vent cabinet, utilize air exhauster that the gas and the dust that produce are taken away, because draught hood also has certain distance apart from operating desk, in the process of gas and dust rising, be easy to be higher than operator's suction of operating desk, thereby operator's health is threatened.And some dust proportion is bigger, be difficult to rise taken away, on the contrary at the effect low suspension of air exhauster in the air, operator's health is worked the mischief.
The utility model content
Technical problem to be solved in the utility model provides the laboratory hood of a kind of easier gas bleeding and dust.
The laboratory hood that its technical problem that solves the utility model adopts, comprise cabinet, be arranged on operating desk, draught hood, air exhauster and airduct in the cabinet, described draught hood links to each other with air exhauster by airduct, described draught hood be installed in operating desk below, described operating desk is provided with the through hole that is communicated with the draught hood cavity.
Further be that the distribution area of through hole is between the 0-1/2 of operating desk width and in the side near the cabinet backboard.
Further be that through hole evenly distributes in distribution area.
Further be that through hole distributes by arranging in length and breadth.
Further be that through hole distributes by circle.
Further be that this laboratory hood is made by stainless steel.
The beneficial effects of the utility model are: utilize the draught hood that is arranged on the operating desk back side, gas and dust that experiment produces are taken away from operating desk, so just can avoid dust because the problem that deadweight can't upwards be taken out, gas is promptly taken away from below after generation, can not influenced the operator who is higher than operating desk.Through hole can also be arranged on the side near backboard, thereby realizes testing in the operating desk outside, bleeds in the operating desk inboard, does not disturb mutually each other.Through hole can evenly distribute, thereby keeps all keeping in the cabinet clean.Laboratory hood can also adopt stainless steel to make to strengthen corrosion resistance.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Parts, position and numbering among the figure: cabinet 1, operating desk 2, draught hood 3, airduct 4, through hole 5, backboard 6.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises cabinet 1, be arranged on operating desk 2, draught hood 3, air exhauster and airduct 4 in the cabinet 1, described draught hood 3 links to each other with air exhauster by airduct 4, described draught hood 3 be installed in operating desk 2 below, described operating desk 2 is provided with the through hole 5 that is communicated with draught hood 3 cavitys.The back side of operating desk 2 is places the opposite one side of experimental article.At this moment, air exhauster is to take out from top to bottom, but not taking out from the bottom up in the past.The gas that the produce this moment directly through hole 5 from the operating desk 2 is discharged, and the operator normally is higher than operating desk, and gas produces just down motion of back, thereby has avoided the influence of gas to the operator.The dust that produces in experiment is owing to the reason of proportion can fall usually, and just in time be to bleed from top to bottom this moment, makes dust to discharge from through hole rapidly, avoids polluting working environment, has protected operator's health.
Operate on operating desk 2 for the ease of the operator, as shown in Figure 1, the distribution area of through hole 5 is between the 0-1/2 of operating desk 2 width and in the side near cabinet 1 backboard 6.According to general operating habit all is to operate near a side of door, and through hole 5 is arranged on the side near backboard 6, both can experimental article not impacted, and also can not influenced by experimental article.
On the basis of above technical measures, as shown in Figure 1, through hole 5 evenly distributes in distribution area.Equally distributed through hole 5 can avoid cabinet 1 interior gas flow inhomogeneous, thereby makes whole cabinet 1 integral body keep clean.
The arrangement mode of through hole 5 can be arranged according to actual needs, for example distributes or distributes by circle by arranging in length and breadth.
Gas that produces in experiment and dust all have certain corrosivity, and in order to strengthen corrosion resistance, this laboratory hood is made by stainless steel.So just, can increase the service life of laboratory hood.
