Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, this utility model is described further：
As shown in figure 1, a kind of be used for experimental laboratory air exhausting device, including wind channel tube, air register 2 and deep bead 3；The air channel
Manage and be made up of stainless steel material, including main air duct 1, light breeze road 5 and three-level air channel 6；The main air duct 1, light breeze road 5 and three
Fixed seal connection between level air channel 6, preventing wind channel tube from crack occur affects exhaust effect.The main air duct 1 and light breeze road 5
Cylinder is disposed as, the diameter of light breeze road 5 is slightly less than the diameter of main air duct 1；Open up between the main air duct 1 and light breeze road 5
There is discharge outlet 4, L-type round pipe is installed in the discharge outlet 4；Temperature has differences during air exhausting device air draft, causes pipe
Interior part condensation forms condensed water, and condensed water slides on tube wall；Space between due to existing between main air duct 1 and light breeze road 5
Gap, condensed water is gathered in spaced slot when slide downward, then is drained by the Jing L-type round pipes of discharge outlet 4, it is to avoid condensation
Water is directly instilled on the equipment or desktop of lower section.The three-level air channel 6 is set to funnel type structure, beneficial to controlled wind speed；It is described
Three-level air channel 6 times is provided with screw thread at air port, can be removed stage makeup and costume different exhaust equipments according to the purposes of air exhausting device, if need to drain big
Amount gas, can install flared fan housing at the air port of three-level air channel 6 times, and a large amount of harmful gass are siphoned away as far as possible；If need to drain
Gas flow it is less, common exhaust duct can be installed, specially the gas of local location is excluded.Wherein main air duct 1 is upper
Bore is connected with air exhauster, with reference to air exhausting device and waste gas, the aerosol that the indoor generation of experiment is excluded using realization of air exhauster
Deng harmful substance.
The air register 2 includes metallic rod and handle；The metallic rod is installed in wind channel tube and metal with deep bead 3
Horizontality is kept between bar installation site and the upper bore place plane of wind channel tube；The metallic rod is symmetrical with deep bead 3
It is flexibly connected between overlapping of axles and metallic rod and deep bead 3, the deep bead 3 is rotated by axle of metallic rod；It is described to keep out the wind
