Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the slag milling system heat balance control device comprising PLC controller, is mounted on industrial personal computer
The moisture on-line detector 1 of 2 top of slag conveyor belt, the hot wind being mounted on the hot air duct being connect with vertical roll grinder 3
Electrically operated valve 4, the cold wind electrically operated valve 7 being mounted on the cold air duct connecting with vertical roll grinder 3 are mounted on and hot-blast stove company
Fuel electrically operated valve 8 on the fuel inlet pipe connect and the combustion fan 6 being connected with hot-blast stove by combustion-supporting air piping, mine
Slag is sent into vertical roll grinder 3 by slag conveyor belt 2, is connect below vertical roll grinder with hot-blast stove 5, and hot-blast stove is to vertical rolls
Hot wind is passed through in grinding machine, hot air duct, cold air duct one end are connected by circulation air piping with vertical roll grinder, hot air duct
The other end is connected with hot-blast stove, and the cold air duct other end is in communication with the outside, and PLC controller is electrically connected with industrial personal computer by conducting wire
It connects, moisture on-line detector, hot wind electrically operated valve, cold wind electrically operated valve, fuel electrically operated valve, combustion fan are controlled with PLC respectively
Device processed is electrically connected by conducting wire.
The object of above-mentioned PLC controller control has the fuel electrically operated valve, hot wind electrically operated valve, cold wind of hot-blast stove electronic
Valve, while acquiring vertical roll grinder run signal, slag conveyor belt run signal, slag moisture on-line detection signal and mine
Slag feeding coal signal.
Above-mentioned PLC selects the S7-1500 series CPU1516 of Siemens Company, and industrial personal computer selects Siemens Company
SIMATIC IPC3000 SMART。
The slag milling system heat balance control device of the utility model obtains mine using moisture on-line monitor in advance
The moisture content of slag enters slag milling system with slag using slag moisture signal is obtained according to the measured value of moisture content
Between time difference, in advance adjust grinding system heat supply, come equilibrium water conten fluctuation on the thermally equilibrated influence of grinding, reach and cut
The regulating effect of peak load.
Slag milling system heat balance dynamic regulation method main target is that slag milling system outlet temperature is maintained to stablize,
Most important regulating measure is the aperture by adjusting fuel electrically operated valve；When the aperture of fuel electrically operated valve reaches maximum still
System heating is not able to satisfy when require, cooperation hot wind electrically operated valve aperture increases, cold wind electrically operated valve aperture reduce come it is real
Now adjust purpose；When the aperture of fuel electrically operated valve reach it is minimum be not able to satisfy system cooling still and require when, cooperation heat
Wind-powered electricity generation movable valve aperture reduces, adjusting purpose is realized in cold wind electrically operated valve aperture increase.
By being mounted on the moisture on-line detector above slag conveyor belt continuously to the slag for entering vertical roll grinder
Moisture detected, detection signal access PLC controller analog input channel, PLC controller is by will test data
It is compared with setting data and historical data, judges whether the moisture of current slag supplied materials meets the charging of slag milling system and want
It asks；If PLC controller judges that current slag moisture content is bigger than normal, fuel electrically operated valve aperture is tuned up in advance, and increasing fuel supplies
Ying Liang, and then make the heat supply of the outlet temperature and slag milling system of hot-blast stove that increased trend be presented, for balance by
In material moisture it is higher cause slag milling system temperature reduce and the raised trend of moisture content of finished products；On the contrary, if PLC controller is examined
It is relatively low to measure slag moisture, then under the premise of maintaining slag milling system heat balance, minimizes opening for fuel electrically operated valve
Degree, to reduce energy consumption.
In addition, the slag milling system heat balance control device of the utility model, PLC controller acquisition in the course of work
Vertical roll grinder run signal, slag conveyor belt run signal and slag feeding coal signal, it is only normal in above-mentioned signal
In the case of, PLC controller just judges that current slag milling system is in normal operating conditions, at this time could be by slag moisture on-line
Signal is detected as hot wind electrically operated valve, cold wind electrically operated valve, fuel electrically operated valve and adjusts foundation, if the appearance of above-mentioned signal is different
Often, PLC controller will be released and be automatically adjusted, and transfer to operative employee according to on-site actual situations to operate.
The above is only the preferred embodiment of the present invention, rather than limitations of the present invention, is not departing from this
In the case where the spirit and scope of utility model, all equivalent changes and modifications made according to the patent scope of the utility model,
Should all it belong within the scope of patent protection of the utility model.
