Existing negative pressure weighing room, in order to reach the vertical one-way gas flow flow pattern of GMP code requirements, generally adopts PVC bars
Shape is held court from behind a screen and will weigh operating space and separate with background area, sees Fig. 1, personnel and material turnover weighing operating space be required for through
PVC bar shapeds are held court from behind a screen 80-1, and using inconvenience, and hold court from behind a screen easy laying dust, easily aging, cleaning difficulty of PVC is big, therefore making of holding court from behind a screen of PVC
Periodic replacement is needed with short life, production cost is also increased.Although also to occur in that weigh indoor setting air curtain in negative pressure at present
Machine, the air curtain produced by air curtain weighs isolating for operating space and background area to reach, but air curtain is deposited in running
In the problem that noise is big, vibration is big, so as to impact to the stability of negative pressure weighing room, normal weighing operation is affected.
The content of the invention
The invention provides the gas curtain partition apparatus of negative pressure weighing room, it can solve existing employing PVC holds court from behind a screen and is weighed
Operating space separates the inconvenient use for existing, easy laying dust, easily aging problem with background area, can also solve the noise of air curtain presence
Greatly, big problem is vibrated, it is ensured that the reliability service of negative pressure weighing room.
The gas curtain partition apparatus of negative pressure weighing room, the negative pressure weighs interior and is provided with weighing operating space, rear channels and top
Portion's passage, is provided with plenum chamber in the top passageway, it is efficient that the top air inlet of the weighing operating space is provided with supply and exhaust
Filter, the plenum chamber is located at the top of the supply and exhaust high efficiency particulate air filter, and the bottom of the rear channels is provided with just effect
Filter and medium effeciency filter, are provided with centrifugal blower, centrifugal blower air-out above the roughing efficiency air filter and medium effeciency filter
Mouth connects the air inlet of the plenum chamber by air-supply airduct, it is characterised in that：It includes gas curtain high efficiency particulate air filter, gas curtain air channel
And gas curtain plenum chamber, the anterior exhaust outlet side in the top passageway positioned at plenum chamber is provided with the gas curtain high efficiency filter
Device, the air outlet of the gas curtain high efficiency particulate air filter is connected by the gas curtain air channel with gas curtain plenum chamber, the gas curtain plenum chamber
Gas curtain air outlet is provided with, the gas curtain air outlet is located at the entrance top of the weighing operating space.
Further, the air outlet of the gas curtain high efficiency particulate air filter is located at underside of forward.
The beneficial effects of the present invention is：It in the anterior exhaust outlet side of plenum chamber by arranging gas curtain high efficiency filter
The air outlet of device and the gas curtain high efficiency particulate air filter is connected by special gas curtain air channel with gas curtain plenum chamber, is sent so as to utilize
The pressure reduction of air draft high efficiency particulate air filter and gas curtain high efficiency particulate air filter provides more than 6m/s wind speed vertically downward, shape to gas curtain exhaust vent
Into clean gas curtain, clean gas curtain will negative pressure weigh indoor weighing operating space and separate with external context environment, it is thoroughly got rid of
Abandon to have been held court from behind a screen using traditional PVC and weigh by the way of operating space and background area to separate, be easy to the turnover of personnel and material, and had
Have the advantages that it is aseptic, without dust stratification, no cross contamination, without individually being cleaned, greatly save regular maintenance cost；And
And it is also without adopting Windscreen Fan, therefore also effectively prevent noise and vibrate big problem, it is ensured that weighing can
By operation.
Description of the drawings
Fig. 1 is the structural representation of existing negative pressure weighing room；
Fig. 2 is the structural representation using the negative pressure weighing room of gas curtain partition apparatus of the present invention.
Specific embodiment
See in Fig. 2, the gas curtain partition apparatus of negative pressure weighing room, negative pressure weighing room 10 that being provided with weighing operating space 11, rear portion leads to
Plenum chamber 50 is provided with road 12 and top passageway 13, top passageway 13, the top air inlet of weighing operating space 11 is provided with to be sent
Air draft high efficiency particulate air filter 60, plenum chamber 50 is located at the top of supply and exhaust high efficiency particulate air filter 60, and the bottom of rear channels 12 is provided with
The top of roughing efficiency air filter 20 and medium effeciency filter 30, roughing efficiency air filter 20 and medium effeciency filter 30 is provided with centrifugal blower 40, from
The air outlet of heart blower fan 40 connects the air inlet of plenum chamber 50 by air-supply airduct 70, and it includes gas curtain high efficiency particulate air filter 81, gas curtain
The anterior exhaust outlet side of plenum chamber 50 is provided with gas curtain in air channel 82 and gas curtain plenum chamber 83, top passageway 13 efficient
Filter 81, the air outlet of gas curtain high efficiency particulate air filter 81 is connected by gas curtain air channel 82 with gas curtain plenum chamber 83, gas curtain plenum chamber
