Abstract
The utility model relates to a fume cupboard which comprises a box body. The bottom of the box body is provided with an operation table; the top of the box body is provided with an exhaust device; one side of the box body is provided with at least three leaves of sliding doors; the sliding doors are provided with operating holes; and at least three sealing slices are arranged in the operating holes. When the structure is adopted, in an experiment, a hand can pass through the sealing slices to extend into the box body; and after the experiment is finished, the operating holes can be completely sealed by the sealing slices, so that the fume cupboard is convenient to control chemical smoke.
Description
Technical field
The utility model belongs to experimental facilities field, is specifically related to a kind of fume hood.
Background technology
Fume hood, claims again fuming cupboard or vent cabinet, is laboratory, particularly a kind of main equipment of chemical laboratory.Purposes is to reduce contacting of experimenter and pernicious gas.Completely completely cut off and need to use glove box.Fume hood is the primary barrier that protection personnel prevent poisonous chemical flue gas harm.It can be used as important safe backuup equipment, and as at chemical experiment procedure failure, chemical fumes, dust and toxic gas effectively exhale pernicious gases while producing, protection staff and laboratory environment.
The workspace of existing fume hood is generally open type or semienclosed, like this when testing, thereby its exist have that chemical substance overflows may be to the hurtful problem of experimenter's health.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of fume hood that can effectively reduce chemical fumes while testing with fume hood providing.
The purpose of this utility model is achieved in that
A fume hood, it comprises casing, bottom half is provided with operating desk, top is provided with exhaust apparatus; Described casing one side is provided with at least three fan sliding doors, and sliding door is provided with handle hole, and at least three sealing sheets are installed in handle hole.
Above-mentioned sealing sheet is rubber fan-shaped flake, and the arc tips of rubber fan-shaped flake and the hole wall of handle hole are fixed, and a plurality of sealing sheets can cover handle hole completely.
Above-mentioned casing is glass casing.
Above-mentioned exhaust apparatus is vavuum pump or lampblack absorber, and its exhaust outlet is connected with discharge duct.
The utility model has been obtained following technique effect:
While adopting said structure, when testing, staff can stretch in casing through sealing sheet, after finishing experiment, can pass through the complete " locked in " operation of sealing sheet hole, facilitates the control of chemical fumes;
Having adopted sealing sheet is rubber fan-shaped flake, the arc tips of rubber fan-shaped flake and the hole wall of handle hole are fixed, a plurality of sealing sheets can cover the structure of handle hole completely, like this staff can not only be at an easy rate through rubber seal thin slice testing freely, and can be after staff be extracted out from casing " locked in " operation hole automatically;
Having adopted casing is the structure of glass casing, can facilitate experimenter's observation experiment process;
Having adopted exhaust apparatus is vavuum pump or lampblack absorber, and the structure that its exhaust outlet is connected with discharge duct can be extracted the chemical fumes in casing out efficiently.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A fume hood as shown in Figure 1, it comprises casing 1, bottom half is provided with operating desk 2, top is provided with exhaust apparatus 3; Described casing 1 one sides are provided with at least three fan sliding doors 4, and sliding door 4 is provided with handle hole 5, and at least three sealing sheets 6 are installed in handle hole 5.
Above-mentioned sealing sheet 6 is rubber fan-shaped flake, and the hole wall of the arc tips of rubber fan-shaped flake and handle hole 5 is fixed, and a plurality of sealing sheets can cover handle hole 5 completely.
Above-mentioned casing 1 is glass casing.
Above-mentioned exhaust apparatus 3 is vavuum pump or lampblack absorber, and its exhaust outlet is connected with discharge duct 7.
Adopt said structure, first the container that chemicals is housed is put on the operating desk 2 of casing 1, then after opening exhaust apparatus 3, test, when testing, staff can stretch in casing through sealing sheet, after finishing experiment, can pass through the complete " locked in " operation of sealing sheet hole.
