Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention can be easier to
In being readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes:
1, primary wind pipe；2, valve；3, sampling pipe；4, exhaust pipe；5, valve；6, negative pressure nozzle；7, pressure regulator valve；8, valve；
9, gas source pipe；10, separator；11, cylinder；12, level-sensing device；13, feeding mold；14, valve；15, scavenging conduit；16, oil hydraulic cylinder；

Working method are as follows:
1, sampling operation original process is shown in that Fig. 2,14 valve of part are in 5 valve opening of closing → part → 8 valve opening of part → gas source
Compressed air pass through negative pressure nozzle (Wen Qiuli pipe principle), 2 valve opening of negative pressure → part → utilization is generated at negative pressure nozzle and is born
The pressure generated at pressure nozzle by coal dust in primary wind pipe and enters into separator, and by separation, coal dust is fallen into lower tube
In 13 feeding mold of road part → terminate → 8 valve of part closing when he separates sampling operation when coal dust amount reaches 12 level-sensing device position of part
8 valve of → part, 5 valve of part simultaneously close off.
2, powder feeding sample workflow is shown in that Fig. 3,18 punch-pin of part are in upper → 22 ejector beam of part and are in 11 cylinder of bottom → part
To under, powder automatically falls into cavity plate → part part 11 for 13 feeding mold advance of impeller → 13 feeding mold hole location of part and die hole
13 feeding mold of cylinder impeller, which pushes back reset → powder feeding sample work, to be terminated.
3, coal dust cake sample preparation workflow is shown in Fig. 4: 16 oil hydraulic cylinder impeller of part, 18 punch-pin moves downward, and presses and protects with cavity plate
After the completion of pressure → pressure maintaining, 16 oil hydraulic cylinder drivening piece of part, 18 punch-pin move upwards 21 oil hydraulic cylinder drivening piece of reset → part, 22 ejector beam to
Upper movement will suppress coal dust cake sample ejection cavity plate.
4, clean remaining powder workflow and see Fig. 4: 2 valve of part is in close state, 5 valve of part is in close state → part 8
Valve is opened, 14 valve opening of part → last time is not run out coal dust under the drive of gas source compressed air, is arranged from 15 scavenging conduit of part
After entering in primary air piping → purging 5 seconds, 8 valve of part is closed, 14 valve closing of part → cleaning terminates.
5, coal dust cake is transferred on detection process platform by system by 23 manipulator of part from cake mold processed, sees Fig. 5.
6, laser detection coal dust cake sample workflow: the automatically controlled XY axis slide track component of part 26 is mobile, keeps laser head alignment coal crooked
Cake sample → laser generator work, makes 24 laser head calcination coal dust cake sample of part, calcination is no less than 200 times, and every calcination is no less than 5
The 27 PC computer of spectrum → part that secondary → 25 optical lens of part acquisition coal dust cake is issued by calcination, to acquisition spectrometer point counting analysis
Afterwards output coal dust elemental composition and the coal dust cake sample that will test of each element content value → 23 manipulator of part be thrown into recovery cylinder →
Testing and analyzing work terminates.
7, a kind of on-line automatic analysis system of coal-burning power plant's First air coal dust element completes once to sample detection and analysis entirely
Process.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
