The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to shown in Fig. 1 to Fig. 3, a kind of negative pressure isolated operation platform comprises bacteria-free isolated operation casing 100, the top of bacteria-free isolated operation casing 100 has air circulation chamber 200, bottom is return air chamber 400, bacteria-free isolated operation casing 100 middle parts are operating room 101, antetheca at operating room 101 is provided with a pair of handle hole 110, and handled easily personnel both hands operate by this handle hole 110.
Air blast 210 is installed in air circulation chamber 200, air blast 210 and PLC control system control connection.And between air circulation chamber 200 and the operating room 101 of bacteria-free isolated operation casing 100, a shunting member 300 is installed.Shown in Fig. 4 and Fig. 5, shunting member 300 comprises framework 301, the middle part of framework 301 is provided with a cross bar 310, cross bar 310 is along the length direction setting of operating room 101, and the two ends of cross bar 310 are connected to framework 301 left and right sides, on cross bar 310, be arranged at intervals with along its length some air-permeating holes 311, the below of each air-permeating hole 311 is provided with guide edge 312, guide edge 312 tilts laterally, and its angle of inclination can be determined according to concrete working environment.Between the inner side of cross bar 310 and framework 301, be equipped with the first ventilated membrane 320, between cross bar 310 and the outside of framework 301, be equipped with the second ventilated membrane 330, wherein the air permeability of the first ventilated membrane 320 is less than the air permeability of the second ventilated membrane 330.
Operating room 101 bottoms are provided with the return air channel 410 being communicated with return air chamber 400 and air blast 210, in return air channel 410, along return air direction, two filters 610,620 are installed.For convenient working condition of observing operating room 101, the side of bacteria-free isolated operation casing 100 is provided with double-layer transparent glass form 102.
In conjunction with shown in Fig. 6 to Fig. 8, the wind that air blast 210 is produced by boasting enters in operating room 101 through shunting member 300, and owing to shunting the effect of member 300, the wind band 510,520,530 that the wind of being produced by boasting by air blast 210 can be divided into three layers of different wind speed after member 300 through shunting enters in operating room 101, and the wind speed that wherein enters the middle level wind band 520 of operating room 101 through air-permeating hole 311 is greater than through the first ventilated membrane 320 and the second ventilated membrane 330 and enters the internal layer wind band 510 of operating room 101, outer wind band 530.Because the air permeability of the first ventilated membrane 320 is less than the air permeability of the second ventilated membrane 330, so the wind speed of internal layer wind band 510 is less than the wind speed of outer wind band 530, the wind speed of internal layer wind band 510 is 0.1m/s～0.4m/s, guarantee that operating room 101 has good gentle operating environment, and this wind speed can not affect performance accuracy.
Operation principle of the present invention is as follows:
Open after air blast 210, the wind speed of middle level wind band 520 is obviously different from internal layer wind band 510 and outer wind band 530, middle level wind band 520 forms an air curtain, internal layer wind band 510 and outer wind band 530 are separated, and there will not be turbulent flow between internal layer wind band 510 and outer wind band 530, just can not mix yet, thus particle can not and internal layer wind band 510 and outer wind band 530 between flow, middle level wind band 520 plays isolates and stable effect.The air of outer wind band 530, suspension, external gas etc. all can not enter internal layer wind band 510 by middle level wind band 520, surrounding air in internal layer wind band 510, material component etc. can not enter outer wind band 530 by middle level wind band 520, so internal layer wind band 510 forms a subnormal ambient, guarantee to have high-cleanness, high environment in internal layer wind band 510, the trend of wind is as shown in the arrow in Fig. 7 and Fig. 8.
And the wind of internal layer wind band 510, middle level wind band 520, outer wind band 530 filters through two filters 610,620 after entering return air channel 410, in air-flow after two filters 610,620 filter, there is 10% air-flow to be discharged into bacteria-free isolated operation casing 100 outsides, there is 90% air-flow again by shunting member 300, to enter operating room 101 after air blast 210, realize circulation air blast, guarantee the continuity of work.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
