Air-supply part: comprise that stepless change blower fan (GMS-900F) and footpath become right-angle bend.Stepless change blower fan is connected with the osculum end that footpath becomes right-angle bend by variable valve;
Sample experiment tube part: comprise experiment tube, quick connecting valve, slot and sampling plate.One section of experiment tube becomes right-angle bend big opening end with footpath and is connected, the other end of experiment tube is connected with the testing tube in part of detecting, in experiment tube, intracardiac both sides are respectively welded with a slot, and sampling plate, by this slot loading test pipe, is pulled out so that sampling plate makes smooth advances;
Part of detecting: comprise that anemoscope (GM8901), testing tube, DS-FC handheld-type intelligent Dust Testing Instrument and dust concentration measuring mouth form.One end of testing tube is connected with the experiment tube in sample experiment tube part, and the other end is gas vent, and the part of detecting of anemoscope is radially fixed in testing tube, and the air speed value display section of anemoscope is placed in outside testing tube; Be positioned at and on the testing tube after anemoscope, have dust concentration measuring mouth, DS-FC handheld-type intelligent Dust Testing Instrument is arranged on dust concentration measuring mouth and sentences and just test out dust concentration value.
advantage of the present invention and beneficial effect:
The present invention can go out the critical wind velocity value that foam colloidal sol suppresses dust for quantitative test, thereby a kind of actual measurement instrument of quantitative evaluation is provided for further researching and developing the new formula of more efficient foam colloidal sol.The present invention also can be applicable to quantitative test and has surperficial cohesiveness for suppressing the anti-dust effect of the material of bulk goods.The application of achievement of the present invention will suppress the technology such as dump airborne dust, harbour bulk goods airborne dust for research and development, the new method that provides quantitative test to analyze, and the present invention has very wide application prospect in research and development field.
