The operation principle of beam type kiln injection system is described as follows:
Beam type kiln injection system can connection in series-parallel under PLC system control, follow procedure works automatically, and flow process is as follows:
When normally jetting, upper ullage is put, upper tank inlet valve, air bleeding valve, upper tank outlet valve, lower tank inlet valve and balanced valve
Being in closed mode, the winding-up of lower tank and fluidisation source of the gas uninterruptedly to supply, rotary feeder is run by setting speed.Instantly tank thing
Material is less than low material position, and level-sensing device sends signal, and upper tank air bleeding valve is opened, and in release, the remaining pressure of tank, balanced valve and intermediate valve are still
Being closed, until upper pressure tank shows that pressure tank drops to 0.02MPa, upper tank inlet valve is opened, and opens material simultaneously
Storehouse outlet fluidisation source of the gas, starts charging, and during charging, upper pot bottom fluidisation source of the gas is opened, and prevents tank solid accumulation from luming.When
Upper the most canned when expecting high charge level, level-sensing device sends signal, and after of short duration time delay, upper tank inlet valve and air bleeding valve are closed successively,
Charging stops.Now, upper pot bottom fluidisation source of the gas is not still stopping to enter tank, and the rising of upper pressure tank, when upper pressure tank and lower tank
When pressure reaches consistent, upper tank outlet valve, lower tank inlet valve are opened, and upper tank coal dust falls into lower tank in self gravitation effect, for
Help blanking, the INO of upper tank top, now, carry gas source and flow amount by throttle valve control, make to be passed through the gas of the pump housing
Measure constant.After the setting time, upper canister incoming gas valve cuts out, and balanced valve is opened.After a period of time has passed, upper tank fluidisation source of the gas,
Upper tank outlet valve, lower tank inlet valve and balanced valve are closed, and complete to pour in down a chimney.Instantly when tank material drops to low material position, upper tank air bleeding valve
Opening, upper tank starts new round charging, so completes a cycle of operation.
Rotate feed pump and be mounted with weighing system, by weighing controller, calculate actual injecting velocity, with control system
Set spouting velocity relatively after, by adjust rotary feeder motor speed, make actual injecting velocity reach setting value, it is ensured that
Winding-up precision.The conveying capacity of material the most all can be regulated by picture.
When system will occur blocking, carrying the pressure change of gas in causing pipeline, now control system can be according to detection
Automatically adjust delivery rate to signal, it is to avoid blocking.Just in case there is blocking, system can be automatically stopped rotary feeder and pass
Closing conveying gas, after in pipeline, pressure drops to 2.0Mpa by the time, system can automatically open up the control valve of conveying gas, through repeatedly opening
Close control valve, after material is carried out continuous featheriness, blocking can be removed.
System possesses various warning function.If situations such as system generation plugging, bleed pressure are low, system will be reported to the police.System exists
During winding-up, once pipeline pressure raises and reaches predetermined warning value, and control system will send alarm signal, enters unimpeded
Process.
The self-diagnostic function arranged by system, can be with the working condition of in-circuit diagnostic system each several part.When certain level-sensing device, enter
There is abnormality in material valve, intermediate valve, balanced valve or pressure switch, and when even breaking down, self-diagnosable system can be pinpointed the problems
Place, reminds operator to process in time simultaneously.
