Ash is quantitatively received in the fly ash constant speed sampling for carrying out further instruction present invention offer below by specific operation process
Automatic carbon testing device：(1), switch on power, in flue, in flow velocity sampler 29, sampling gun, flow velocity sampler 31 starts to measure flue 1
Gas-solid mixture flow velocity in interior gas-solid mixture flow velocity and sampling gun barrel 27, and flow velocity is converted into the signal of telecommunication while transmission
A Regulate signal is produced through computing and is sent to negative pressure generator 28 to signal controller 10, signal controller 10, negative pressure is sent out
Raw device 28 produces negative pressure to start to adjust, the gas-solid mixture after the short time in sampling gun barrel 27（Fly ash particulate and mixed gas）
Start to move into cyclone separator 7 and flow velocity is reached unanimity with the gas-solid mixture flow velocity in flue 1（By pid algorithm
Tracking）；(2), after the gas-solid mixture flow velocity in the gas-solid mixture and flue 1 sampled in gun barrel 27 reaches unanimity, signal control
Device processed 10 sends drive signal to lower valve cylinder 12, and lower valve cylinder 12 obtains electric backward front promotion and receives ash lower valve plate 34, quantitative receipts ash
Mechanism 38 proceeds by and collects ash sample；During ash sample is collected, when signal controller 10 detects the letter of powder material sensor 36
Stopping collecting ash sample after number, and drive signal being sent to upper valve cylinder 13, upper valve cylinder 13 promotes the upper valve plate 35 of receipts ash to close, this
When receive grey lower valve plate 34 and receive the ash sample that the ash sample between the upper valve plate 35 of ash is as quantitatively collected；(3), ash sample is quantitatively collected and is completed
Afterwards, signal controller 10 sends drive signal to travel mechanism 19, when travel mechanism 19 moves to ash tube 15 lower section of sealer,
Elevating mechanism 21 drives crucible supporting plate 32 to move up until clinging to crucible 33 and on ash tube sealer 15 wait ash；
(4), signal controller 10 sends drive signal to lower valve cylinder 12, and lower valve cylinder 12 pulls back the grey lower valve plate 34 of receipts, quantitative receipts
Ash sample in grey mechanism 38 persistently can be dropped in crucible 33, after the quantitative ash sample that collects is entirely fallen in crucible 33, lifting
Mechanism 21 drives crucible supporting plate 32 to be moved downwardly to initial position wait；(5), signal controller 10 sends drive signal to shifting
Motivation structure 19, travel mechanism 19 are sent to crucible 33 immediately below heating calcination device 18, and heating calcination device 18 starts to dry crucible
The moisture of ash sample in 33, regularly after 1 minute, crucible 33 is moved to directly over weight detecting mechanism 23, now by travel mechanism 19
Elevating mechanism 21 moves down crucible supporting plate 32, and the crucible 33 in crucible supporting plate 32 slowly falls into weight detecting mechanism 23
On；(6), weight detecting mechanism 23 starts to carry out crucible 33 weight measurement, and continuously transmits multiple quality signal and give signal control
Device 10, and be M1 (the non-calcination ash sample quality of crucible mass M 0+) by this quality status stamp；(7), crucible 33 is transmitted by travel mechanism 19
To heating calcination device 18, Rodless cylinder 25 drives ceramic push rod 24 that crucible 33 is upwardly into heating calcination device 18
Portion, and begin to warm up burning, after the heating burning a period of time of crucible 33, Rodless cylinder 25 drive ceramic push rod 24 by crucible 33 from
Heat downward out in calcination device 18 and cool down wait；(8), after the completion of, cooling down, crucible 33 is sent to weight by travel mechanism 19 again
Directly over amount detection machine structure 23, now elevating mechanism 21 moves down crucible supporting plate 32, the crucible 33 in crucible supporting plate 32
Slowly fall on weight detecting mechanism 23；(9), weight detecting mechanism 23 starts to carry out crucible 33 weight measurement again, and even
Supervention send multiple quality signal to signal controller 10, and is M2 (ash sample matter after crucible mass M 0+ calcination by this quality status stamp
Amount)；(10), signal controller 10 by formula W phosphorus content=（M1-M2）/（M1-M0）* 100% carbon containing for calculating fly ash combustible material
Amount, and shown in touch display screen 3；(11), phosphorus content shows that finishing rear signal controller 10 sends drive signal to shifting
After motivation structure 19 is sent to crucible 33 immediately below ash discharge tube sealing device 17, elevating mechanism 21 moves up crucible supporting plate 32,
Crucible supporting plate 32 is moved up until crucible 33 is clung to wait ash discharge on ash discharge tube sealing device 17；(12), signal controller
10 send a signal to negative pressure ash ejector 37 starts ash discharge, and after the completion of ash discharge, crucible 33 is sent to initial position by travel mechanism 19；
(13), reciprocation cycle step (1)～(12).
Above-mentioned structure and embodiment show only single-point isokinetic sampling and quantitative receipts ash；In fact, by Sampling Machine
Structure and corresponding quantitative Shou Hui mechanisms are improved, moreover it is possible to realize that multipoint constant-speed sampling receives ash with quantitative.
The present invention automatic carbon testing device combine traditional high-precision laboratory chemical calcination loss method carbon determination technology and
The average rate sampling technique that voluntarily develops, it is achieved that to on-line intelligenceization measurement during the high-precision real of unburned carbon in flue dust；The device is adopted
With PLC as master controller, by integrated isokinetic sampling and the grey function of quantitative receipts, unburned carbon in flue dust can be realized in industry spot
On-line checking, can accurately detect fly ash combustible material index；In addition the device also has manual measurement and manual sampling
Function, therefore suitably promote the use of.
Above example technological thought only to illustrate the invention, it is impossible to which protection scope of the present invention is limited with this, every
According to technological thought proposed by the present invention, any change that is done on the basis of technical scheme, the scope of the present invention is each fallen within
Within；The technology that the present invention is not directed to can be realized by prior art.
