Certain 360m known2Sintering machine proportioning room has 13 feed bins, according to the arrangement of material direction of travel is: 2, storehouse of returning mine, molten
2, agent storehouse, mixes ore storage bin 5, Bunker 2, calculogenesis ash silo 2；Feed bin span is 7.5m, and the most each discharging point spacing is
7.5m, the Belt Length before dispensing outlet to is mixed is 150m, and it is 1.25m/s that tachogenerator 8 records belt-conveying speed perseverance.
The analysis method of described sintering moisture of batch detection analytical equipment, comprises the steps:
Step one: set parameter preset,
Setting parameter preset at central controller 1, described parameter preset includes that each discharging point spacing 7.5m and dispensing go out
Mouthful to Belt Length 150m before mixed；
Step 2: set in belt-conveying speed 1.25m/s detected according to tachogenerator 8 and step one respectively falls
Shots spacing 7.5m, determines that the material of each discharging point 4 to dispensing outlet runs the time；
Step 3: the material discharge quantity of each discharging point detected according to plantwide control system burden balance 7 and corresponding
The blanking moisture of the material that Moisture Meter probe detects, determines siccative amount and the water content of each layer material of each moment；
Step 4: run the time according to the material of each discharging point 4 to the dispensing outlet determined in step 2, determine in dispensing
Siccative amount that exit each layer material is real-time and water content；
It is 162t/h that moment 0s records warehouse receipt storehouse discharge quantity of returning mine, and can calculate this section of material and travel to the second discharging point warp
Time t1, the t1=7.5/1.25=6s crossed, i.e. this section material arrives the second discharging point at moment 6s with belt conveyer 9, surveys
The discharge quantity obtaining this this discharging point of moment is 0t/h；
This section of material arrives the 3rd discharging point at moment 12s with belt conveyer 9, records the blanking of this this discharging point of moment
Amount is 12t/h；
And so on；
This section of material arrives the 13rd discharging point, i.e. dispensing outlet at moment 72s with belt conveyer 9, records this moment
The discharge quantity of this discharging point is 27t/h；
This section of material arrives one at moment 192s with belt conveyer 9 and mixes；
Elapsed time t2, moment 0s the first feed bin material arrives the first moisture measuring point, t2=7.5* (2+2-1)/1.25=
18s, i.e. moment 18s, the first feed bin material of moment 0s arrives the first moisture measuring point, by the Moisture Meter of the first moisture measuring point
Probe 2 to record this moment moisture i.e. blanking moisture be 4%；
And so on；
In summary: in final batch, be made up of following material: a storehouse doses of returning mine is 162t/h, returns mine for No. two
Storehouse doses is 0t/h, and moisture is 0%；A number flux storehouse doses is 12t/h, and barium fluxing agent storehouse doses is 0t/h, and moisture is 4%；
Blending ore warehouse receipt storehouse discharge quantity is 120t/h, and moisture is 6%；A number Bunker doses is 0t/h, and No. two Bunker doses are
32t/h, moisture is 10%；A number calculogenesis ash silo doses is 0t/h, and No. two calculogenesis ash silo doses are 27t/h, and amount of water is 15t/
h；
Siccative amount and water content that at dispensing outlet, each layer material is real-time are respectively as follows:
The siccative amount returned mine=(162+0) * (1-0%)=162t/h,
The water content returned mine=(162+0) * 0%=0t/h,
The siccative amount of flux=(12+0) * (1-4%)=11.52t/h,
The water content of flux=(12+0) * 4%=0.48t/h,
The siccative amount of blending ore=(120+120+120+120+120) * (1-6%)=564t/h,
The water content of blending ore=(120+120+120+120+120) * 6%=36t/h,
The siccative amount of fuel=(0+32) * (1-10%)=28.8t/h,
The water content of fuel=(0+32) * 10%=3.2t/h,
The siccative amount of quick lime=(0+27) * (1-0%)=27t/h,
Water content=the 15t/h of quick lime；
Step 5: siccative amount and water content that at the dispensing outlet that will determine in step 4, each layer material is real-time are carried out respectively
Iteration is sued for peace, and draws siccative amount and water content that at dispensing outlet, batch is real-time, and then draws real-time joining at dispensing outlet
Close material moisture；
Siccative amount=162+11.52+564+28.8+27=793.32t/h that at dispensing outlet, batch is real-time,
Water content=0+0.48+36+3.2+15=54.68t/h that at dispensing outlet, batch is real-time,
Join at water content/dispensing outlet that at moisture of batch=dispensing outlet real-time at dispensing outlet, batch is real-time
Close the siccative amount * 100%=54.68/793.32*100%=6.89% that material is real-time,
This moisture of batch is the real-time moisture of moment 72s；
Step 6: send to factory after moisture of batch delay time T real-time at the dispensing outlet of gained in step 5
Level control system, as the real-time moisture of a batch before mixed, wherein,
The T-batch operation time before dispensing outlet to is mixed, mix according to the dispensing outlet set in step one to
The belt-conveying speed that front Belt Length and tachogenerator 8 detect, can show that batch is before dispensing outlet to is mixed
