Background technology
Potential safety hazard that coal dust is caused and occupational health problem, it has also become China mines, anxious by the industry such as coal, transfer coal
One of key technical problem that need to solve.Therefore, for effectively suppressing coal dust, it is proposed that the foam sol new technology of preventing and treating coal dust.
This technology has stronger surface adhesiveness, can be bonded together firmly on scattered coal surface, it is thus possible to prevent coal dust because of the external world
Disturbance and airborne dust.
Up to now, there are no about the effect determining foam sol suppression coal dust, quantitative test goes out foam sol suppression
The test report of validity limit air speed value during coal dust, it is therefore necessary to develop a kind of for testing foam sol suppression dust
The experimental provision of effect.
Summary of the invention
It is an object of the present invention to provide a kind of experimental provision for testing foam sol suppression dust effect, with quantitative test
When going out the static dust of foam sol suppression, effectively suppress the critical wind velocity value of airborne dust.
The experimental provision for testing foam sol suppression dust effect that the present invention provides, mainly has air section (Fig. 1
Shown in middle A), sample experiments tube portion (in Fig. 1 shown in B) and part of detecting (in Fig. 1 shown in C) composition.
Air section: include that variable speed blower fan (GMS-900F) and footpath become right-angle elbow pipe.Variable speed blower fan is by adjusting
The osculum end that joint valve becomes right-angle elbow pipe with footpath is connected；
Sample experiments tube portion: include experiment tube, quick connecting valve, slot and sampling plate.One section of experiment tube becomes with footpath
Right-angle elbow pipe big opening end is connected, and the other end of experiment tube is connected with the testing tube in part of detecting, intracardiac in experiment tube
Both sides are respectively welded with a slot, and sampling plate is by this slot loading test pipe, in order to sampling plate makes smooth advances pull-out；
Part of detecting: include that anemobiagraph (GM8901), testing tube, DS-FC handheld-type intelligent Dust Testing Instrument and dust are dense
Degree measures mouth composition.One end of testing tube is connected with the experiment tube in sample experiments tube portion, and the other end is gas vent, wind
The part of detecting of speed instrument is radially fixed in testing tube, and the air speed value display part of anemobiagraph is placed in outside testing tube；It is positioned at wind speed
Having dust concentration measuring mouth on testing tube after instrument, DS-FC handheld-type intelligent Dust Testing Instrument is arranged on dust concentration measuring
To test out dust concentration value at Kou.
Advantages of the present invention and beneficial effect:
The present invention may be used for quantitative test and goes out the critical wind velocity value of foam sol suppression dust, thus is research further
Develop highly efficient foam sol newly to fill a prescription the actual measurement instrument of a kind of quantitative assessment is provided.It is also possible to apply the invention to quantitatively survey
Examination has surface adhesiveness for suppressing the anti-dust effect of the material of bulk goods.The application of achievement of the present invention will be for research and development suppression
The technology such as dump airborne dust, harbour bulk goods airborne dust, it is provided that the new method that quantitative test is analyzed, the present invention has in research and development field
The most wide application prospect.

Detailed description of the invention
Embodiment
As it is shown in figure 1, the present invention is provided to test the experimental provision of foam sol suppression dust effect, mainly there are three
Part composition, is air section (in Fig. 1 shown in A) respectively, sample experiments tube portion (in Fig. 1 shown in B) and part of detecting (Fig. 1
Shown in middle C).
Air section: include that variable speed blower fan (GMS-900F) 1, regulation valve 2 and footpath become right-angle elbow pipe 10 and form.Stepless
Speed-changing draught fan 1 becomes right-angle elbow pipe 10 osculum end by regulation valve 2 with footpath and is connected, and footpath becomes right-angle elbow pipe 10 big opening end by quickly
Connect valve 3 to be connected with one end of the experiment tube 11 of sample experiments tube portion B.
Sample experiments tube portion: include that experiment tube 11, quick connecting valve 3 and 5, slot 4 and sampling plate 13 form.Experiment tube
One end of 11 is become right-angle elbow pipe 10 big opening end with footpath and is connected by quick connecting valve 3, and the other end of experiment tube 11 is by quickly
Connecting valve 5 to be connected with the testing tube 12 in part of detecting, slot 4 is welded on center two side position of experiment tube 11, sampling plate
13 put into experiment tube 11 by slot 4.
Part of detecting: include that anemobiagraph (GM8901) 6, dust concentration measuring mouth 7, DS-FC handheld-type intelligent dust are tested
Instrument 8 and testing tube 12 form.Testing tube 12 one end is connected with experiment tube 11 by quick connecting valve 5, anemobiagraph (GM8901) 6
Part of detecting radially fixed in testing tube 12, the air speed value display part of anemobiagraph (GM8901) 6 is placed in outside testing tube 12；
Having dust concentration measuring mouth 7 after being placed in anemobiagraph (GM8901) 6 on testing tube 12, DS-FC handheld-type intelligent dust is tested
Instrument 8 tests out dust concentration value by dust concentration measuring mouth 7；Outside gas is by outlet 9 discharge experimental provision.
The regulation valve 2 installed in Fig. 1 can regulate the air force entering experiment tube the most respectively.
Specific experiment process is as follows:
First, take 5-10 gram of dust pile to be placed in the middle of sampling plate；Then, the powder on sampling plate will be placed on by foam sol
Dirt surface all covers, and after foam sol air-dries, sampling plate is put into the slot of sample experiments tube portion；Finally, connect
After good air section, sample experiments tube portion and part of detecting, gradually increase the air quantity of variable speed blower fan, treat that DS-FC is hand-held
When dust concentration value that formula intelligence Dust Testing Instrument is measured is significantly raised, the air speed value that now anemobiagraph shows is foam sol
The critical wind velocity value of static dust can be restrained.
