Description
Technical field
The utility model relates to a kind of arrow and flows vent cabinet.
Background technology
Experimental implementation produces various dusty gas, foul smell, moisture and inflammable, explosive, corrosive gas often; in order to protect the safety of operator; prevent the pernicious gas in testing from spreading to laboratory, will vent cabinet be used near pollution sources, in time by outside dusty gas discharge chamber.The situation that existing vent cabinet easily has vortex to produce in running, simultaneously poor for the pernicious gas adaptive capacity that density is not of uniform size, often just exhaust air rate must be strengthened to drain the pernicious gas produced in cabinet, this not only adds power consumption, affecting experiment effect, is also a very large obstacle to the comfortableness improving operator.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of arrow to flow vent cabinet.It solve existing vent cabinet and easily produce eddy current in running, the problem of exhaust effect difference.
The technical solution of the utility model is: vow stream vent cabinet, comprises cabinet, filter fan housing and upper cover.
The front panel of cabinet is provided with action pane, and the front panel of action pane upper end is evenly equipped with multiple air admission hole, and small portion of gas enters operating cavity by the air admission hole in the front panel of cabinet, and bottom of cabinet bulk is provided with base plate, and cabinet upper end is uncovered;
The segmental arc that filter fan housing comprises straight plate section and is connected with straight plate section upper end, segmental arc is provided with a plurality of filter air holes;
Upper cover top is provided with air outlet;
Filter fan housing to be located in cabinet and will to be divided into operating cavity and discharge chamber in cabinet, its dual-side is connected on the inwall of cabinet both sides, be provided with gap between its lower end and cabinet base plate, operating cavity and discharge chamber by gap with filter air holes and be communicated with, upper cover is contained in cabinet upper end open-mouth.
The further technical scheme of the utility model is: it also comprises the shutter be located between cabinet and upper cover, the adjusting knob that shutter comprises frame, blade and is located at outside frame, partition rod is provided with and by the region that is separated in frame for installing blade and ventilating opening in frame, blades installation is in frame, the aperture of blade is controlled by adjusting knob, thus the air output in control operation chamber.Shutter frame lower surface is connected on cabinet upper edge mouth, and its frame upper surface is connected with ora terminalis mouth under upper cover, in discharge chamber, be provided with dividing plate, and dividing plate upper end is connected on the partition rod of framework, and lower end is connected with the straight plate section of filter fan housing.Cabinet lower end is connected with locker.
The utility model compared with prior art tool has the following advantages:
1, avoid pernicious gas to produce vortex in cabinet internal flow, cabinet internal gas flow flow field can being made in vowing stream-like, having stronger adaptability for the pernicious gas that density is not of uniform size, efficiently can drain pernicious gas.Filter fan housing comprises the straight plate section of lower end and the segmental arc of upper end, and it to be located in cabinet and to be operating cavity and discharge chamber by cabinet interior separation.When air exhauster runs, under suction, the outer most of gas of cabinet flows into operating cavity through the action pane of cabinet, small portion of gas enters operating cavity by the air admission hole in cabinet front panel, portion gas subsequently in operating cavity flows into discharge chamber by the gap between filter fan housing and cabinet base plate, another part gas guides along the appearance profile filtering fan housing and evenly rises, then enters discharge chamber through the filter air holes on filter fan housing, and the gas of final discharge chamber is by draining through air outlet after shutter.
2, filter fan housing segmental arc and be provided with filter air holes, air flow method can be made even.Cabinet front panel is provided with air admission hole, cabinet outer air can be made to infiltrate in cabinet, improve Flow Field Distribution, can observe the test situation in cabinet simultaneously.
3, shutter and dividing plate can reduce the flow perturbation of operating cavity.Sometimes need when testing to lay test paper on cabinet base plate, if can not the air output in control operation chamber, then flow perturbation be comparatively large, and test paper easily hikes up from base plate under the suction of exhaust.Between cabinet and upper cover, arrange shutter, and arrange dividing plate in discharge chamber, when after the blade of being closed shutter by adjusting knob, air-flow can only enter discharge chamber by the gap between filter fan housing and base plate, reduces the flow perturbation of operating cavity.
Below in conjunction with figure and embodiment, the utility model is further described.
