Description
Technical field
The utility model relates to vent cabinet.
Background technology
Vent cabinet is a kind of common apparatus in the chemical laboratory.The pre-treatment of chemical experiment, and with volatile reagent configuration solution, often will in vent cabinet, carry out.Often clearing up of sample will be cleared up sample with nitric acid, hydrofluoric acid and perchloric acid etc. on electric hot plate, can produce strong acid mist in the digestion process, and acid mist has severe toxicity and severe corrosive.Therefore the vent cabinet of in-built electrical hot plate requires ventilation and effect of heat insulation well and conveniently to observe and operate.Vent cabinet at present commonly used comprises the cabinet and the cabinet door of push-and-pull up and down, and the cabinet door generally adopts the silex glass door.Existing vent cabinet has the following disadvantages:
First, under the certain situation of vent cabinet power of fan, because the area of cabinet door is bigger, after one-dimensional unlatching cabinet door is opened, because the long-pending big ventilation wind speed of the shop front is slow, cabinet Men Kaide is big more, and wind speed is then slow more, cause the acid mist pump drainage thorough inadequately, experimental implementation person may suck a spot of severe toxicity, severe corrosive acid mist or volatility toxic organic compound when observing or picking and placeing sample particularly inboard on the electric hot plate;
The second, one-dimensional cabinet door is opened when experimentizing operation, and the operator is directly exposed to by the electric hot plate, can feel scorching hot and feel bad;
The 3rd, when clearing up sample with electric hot plate, because the temperature height, Specimen eliminating has often and spatters cruelly even explosion phenomenon takes place, and the experimenter opens when the one-dimensional door is operated and is exposed to fully by the sample, and is careless slightly, gently then burns out clothes, heavy then injured disfeaturing;
The 4th, hydrofluoric acid has strong corrosiveness to silex glass, and the silex glass door of one dimension will soon be corroded becomes translucent ground glass shape, influences the experimenter and observes the cabinet internal state.
The utility model content
The purpose of this utility model is to provide a kind of well-ventilated, safe ready to pick and place the vent cabinet of article in the cabinet.
The technical solution of the utility model is as follows:
A kind of vent cabinet comprises cabinet, the cabinet door of push-and-pull up and down, and the top of cabinet is provided with blast pipe, is provided with the blower fan that links to each other with blast pipe in the cabinet, is provided with operating desk in the cabinet, and the cabinet door is provided with operation window, and the outside of operation window is provided with the operation window.
Further, the operation window is installed on the cabinet door with the door hinge.
Further, the downside of cabinet door is provided with an eaves, and the door eaves is provided with guide rail, and guide rail is provided with the door that swings of one or two left and right sides push-and-pull, swings door and is the operation window.
Further, in order to carry out left and right sides push-and-pull better, swing door and be provided with handle.
Further, described guide rail is " Qian " type guide rail, and " Qian " type guide rail is the guide rail of using always, on it swing door followingly can movable pulley be set, will make slip more smooth and easy after movable pulley is set.Described guide rail also can be the raised line guide rail, swing door below be provided with the groove movable pulley that matches with raised line, the raised line guide rail also is the guide rail of using always, its general and groove movable pulley is used.
Further, the operation window is that suspension type is swung door.
Further, the shape of operation window can be set to square, circular or oval.The purpose of operation window is conveniently to take out or put into sample to vent cabinet, simultaneously also can observe situation in the vent cabinet by operation window, and it is square, circular or oval that its shape is not limited to.Operation window is preferably square, and it is long at 30～120cm, and wide is good in 20～60cm.
Compared with prior art, the utlity model has following advantage:
First, vent cabinet in use, the cabinet door of Kai Qiing can be in closed condition all the time up and down, observe and pick and place laboratory sample by operation window, under the situation that always exhaust air rate is constant,, improved the wind speed of operation window greatly because the area of operation window is little, thereby solved the halfway problem of doorway acid mist pump drainage in clearing up the sample process, thereby the experimenter is observed or can not suck severe toxicity, severe corrosive acid mist or volatility organic poison when picking and placeing on the electric hot plate particularly inboard sample.
The second, limited by the heat of operation window radiation because the cabinet door of Kai Qiing is in closed condition all the time up and down, the experimenter can not feel scorching hot and feel bad.
The 3rd, existing vent cabinet in use, when clearing up sample with electric hot plate, because temperature height, Specimen eliminating has often and spatters phenomenon even explosion phenomenon cruelly and take place, and the human body large tracts of land was exposed to by the sample when experimenter opened the one-dimensional door and operates, and is careless slightly, gently then burn out clothes, heavy then injured disfeaturing; And double door of the present utility model, the cabinet door of Kai Qiing only has an operation window up and down, when being in observation state, operation window goalkeeper's operation window is sealed, the space of realizing experimenter and sample isolates, and when the taking-up sample is observed, only needs a less window to get final product, even explosion phenomenon takes place to spatter cruelly, its injury degree of danger has also reduced a lot.
The 4th, the more employing silex glass of the cabinet door of existing vent cabinet, hydrofluoric acid has strong corrosiveness to silex glass, and the silex glass door of one dimension will soon be corroded becomes the ground glass shape, influence the experimenter and observe the cabinet internal state, and its cabinet door change pretty troublesome, cost is also high.Cabinet door material of the present utility model is not done requirement.If the operation window adopts the silex glass door, after the operation window is corroded into the ground glass shape, can consider that then will operate window changes.The area of operation window is less, and the cost of changing the operation window is very low.
