Description
Technical field
The utility model is related to a kind of weighing room, more particularly to a kind of negative pressure weighing room.
Background technology
Weighing room be it is a kind of be used for the special Local Purification equipment in place such as pharmacy, microbe research and scientific experiment, it
A kind of vertical one-way gas flow is provided, part pure air circulates in workspace, is partly expelled near zone, produces workspace
Raw negative pressure, prevents cross pollution, the high-cleanness, high environment for ensureing workspace.Dust, reagent is carried out in a device to weigh, divide
Dress, can control that dust, reagent are excessive, raise up, prevent the inhalation hazard of dust, reagent to human body, also avoid dust, reagent
The safety of cross pollution, protection external environment and indoor occupant.
Utility model content
The utility model is to overcome prior art not enough to weigh there is provided a kind of negative pressure with high-cleanness, high workspace
Room.
Specifically, a kind of negative pressure weighing room described in the utility model, including casing, be arranged at the air inlet of casing, go out
Air port, be arranged in casing and connection air inlet and the air channel workspace of air outlet and blower fan, the blower fan connection air inlet with
Air outlet, the blower fan is arranged in air channel, and the first filter, the air channel and work are provided between the blower fan and air inlet
The second filter is provided between area, second filter is fixed with stream film and illuminating lamp.
Further, the air inlet is vertical setting with air outlet.
Further, the 3rd filter is provided between the air channel and air outlet.
Further, the filter efficiency of first filter is respectively G3, F8, the second filter and the 3rd filter
Filter efficiency is H14.
Further, if being provided with the pressure gauge of dry measure air pressure in the air channel.
Further, the blower fan is frequency conversion constant speed blower fan.
Negative pressure weighing room described in the utility model, wind speed is constant, it is ensured that the steady air current in operating room, air outlet with
Air inlet is perpendicular, the noise that effectively reduction air channel interior air-flow is produced, and main workspace is using high efficiency filter, stream design, it is to avoid
The cross pollution of dust and reagent, can be weighed to reagent, be encapsulated, and exempt the injury to human body.
Brief description of the drawings
Fig. 1 is the front view of the utility model negative pressure weighing room；
Fig. 2 is the structural representation of the utility model negative pressure weighing room.
Embodiment
Below in conjunction with accompanying drawing, negative pressure weighing room described in the utility model is illustrated without limitation, it is therefore an objective to be
The public more fully understands described technology contents.
As shown in Figures 1 and 2, negative pressure weighing room 100 described in the utility model, for entering to chemicals, reagent etc.
Row measurement, encapsulation, it includes casing 1, the air inlet 11 for being arranged at casing, air outlet 12, is arranged in casing 1 and connects air intake
Mouthfuls 11 with air channel 2, workspace 7 and the blower fan 3 of air outlet 12, the blower fan 3 be arranged between air inlet 11 and air outlet 12 and
In air channel 2, and it is close to air inlet.The blower fan 3 is frequency conversion constant speed blower fan, so as to ensure the stabilization of air-flow.With reference to
Some pressure gauges 14 are additionally provided with Fig. 1, the air channel 2, for measuring the air pressure in air channel.Tank surface is additionally provided with control panel
13, whole negative pressure weighing room is controlled by PLC
The first filter 4 is provided between the blower fan 3 and air inlet 11, the first filter 4 is a first, medium effeciency filter,
Its filter efficiency is respectively G3, F8, and the air-flow for being brought into blower fan 3 is tentatively filtered.
The second filter 5 is provided between the air channel 2 and workspace 7, in other words, air channel 2 is with workspace 7 by the second filtering
Device 5 is connected.The filter efficiency of second filter is H14, to realize the filtering of high cleanliness.Second filter is fixed with
Flow film 9 and the illuminating lamp 8 positioned at its both sides.Stream film makes air-flow further uniform, is flowed into vertically into workspace so as to be formed
Laminar flow.
The 3rd filter 6 is provided between the air channel 2 and air outlet 12, the filter efficiency of the 3rd filter 6 is also H14.
Fraction is flowed out by the 3rd filter 6 and air outlet 12, so that producing negative pressure in workspace 7, prevents the intersection of reagent
Infection.
It is worth noting that, the air inlet 11 is vertical setting with air outlet 12, that is, formd vertically in air channel
Air-flow, advantageously reduce the noise of air current flow.
It should be understood that the above is not the limitation to the technical scheme, in fact, all with identical or approximate original
Manage the improvement carried out to the technical scheme, including the shape of each several part, size, the improvement of material used, and identity function
The replacement of element, all within the technical scheme that the utility model is claimed.
