Description
Technical field
The utility model relates to a kind of vent cabinet.
Background technology
Vent cabinet is that a kind of energy will be done the laboratory ventilation equipment that pernicious gas that experiment produces fully, is in time discharged the work-yard in cabinet, it to prevent the operator suck poisonous, be harmful to, have the gas of peculiar smell to play a very good protection.Usually, the experiment of employing pernicious gas or generation pernicious gas all is arranged in the vent cabinet and carries out.In vent cabinet, a work top that supplies the experimenter to put various laboratory apparatus and experimentize and operate is arranged, when windowpane was opened, the staff carried out experimental implementation before vent cabinet.When windowpane cut out, the experimenter can pass through windowpane observation experiment process, and relevant national standard has stipulated that the key technical indexes of estimating the vent cabinet ventilation effect has: the total exhaust air rate of vent cabinet; Operation centre plane wind speed; The control concentration of operating personnel's breathing zone and vent cabinet resistance.Present common vent cabinet, its entodorsum is one, exhaust outlet is arranged on the top and bottom of entodorsum, when the molecular weight gas that produced of experiment is big, because the height of entodorsum is higher, gas time that moves up and down in cabinet is long, and the possibility of delay is big, causes the control concentration over-standard of operating personnel's breathing zone.For vent cabinet air draft effect is strengthened, then need strengthen the wind speed of blower fan, this will make the wind speed of work top exceed standard.In addition,, form turbulent flow easily, make the wind speed inequality of work top because gas molecule sharply moves up and down.
The utility model content
The purpose of this utility model provides a kind of vent cabinet, and the operating space is big, exhaust, safety, the face wind speed is even, flowing resistance is little, guarantee that the control concentration of operating personnel's breathing zone and gathering hole centre plane wind speed meet national national standard requirement.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of vent cabinet, comprise cabinet, the bottom surface of described cabinet is evenly distributed with four height and adjusts the angle, the bottom of cabinet front panel is provided with the cabinet door, the cabinet door is provided with handle, the medium position corresponding section of the inside of cabinet and described cabinet door is fixed with laminate, the place of keeping to the side, middle part of cabinet front panel is provided with control panel, the gas cock, water cock and socket, the middle part of cabinet is fixed with table top, the place of keeping to the side, bottom of table top is provided with a glass groove, the top of cabinet front panel has air-vent, the top board of cabinet is provided with fluorescent lamp and gas skirt, and the bottom of top board is provided with liner, and the bottom surface of top board and the side of liner be fixing holder all, be fixed with baffle upper plate on the holder from top to bottom successively, middle deflector and chin spoiler, the bottom of described liner are provided with repairs door.
The beneficial effects of the utility model are: the operating space is big, exhaust, safety, the face wind speed is even, flowing resistance is little, air-flow is evenly distributed, and guarantees that the control concentration of operating personnel's breathing zone and gathering hole centre plane wind speed meet national national standard requirement.
