To above-mentioned deficiency; The utility model provides a kind of dried stove dry coke quenching automatic control system and control method put out; It not only can reflect the dried situation of putting out material stock amount in the stove in real time; Be unfavorable for realizing driedly putting out the prison chain control showing and produces in real time of stove material stock amount, and can realize driedly putting out the monitoring in real time of stove material stock amount and controlling.
The technical scheme that its technical matters of the utility model solution is taked is: a kind of dried stove dry coke quenching automatic control system of putting out; It is characterized in that the upper limit material-level detecting device that comprises central controller and be connected with central controller respectively, correction material-level detecting device, coke feeding device, coke discharger and coke transport; Said upper limit material-level detecting device is arranged on dried throwing Jiao Kou place of putting out stove; Said correction material-level detecting device is arranged on the dried position, stove middle and upper part of putting out; Said coke feeding device is used for coke is transported to dried putting out in the stove; Said coke discharger is arranged on dried coke discharging mouth place of putting out stove, and said coke transport is arranged on coke discharging mouth below.
Said central controller adopts the PLC controller.
Said upper limit material-level detecting device comprises the capacitance material level meter.
Said correction material-level detecting device comprises GAMMA ray level-sensing device, and the GAMMA ray irradiation source of said GAMMA ray level-sensing device and GAMMA ray detector are separately positioned on the dried symmetrical position, stove middle and upper part of putting out.
Said coke feeding device comprises the coke lifting gear.
Said coke transport comprises the belt conveyer scale conveyor.
A kind of dried stove dry coke quenching autocontrol method that puts out is characterized in that, may further comprise the steps:
System detects;
Obtain the dried oven coke material stock amount of putting out;
Drop into coke to the dried stove that puts out;
Discharge coke;
System calibration.
Saidly may further comprise the steps to dried pack into the step of coke of stove of putting out:
Start lifting gear and promote coke, and drop into coke;
Detect the input coke and whether reach the upper limit;
Calculate the coke input amount.
The step of said discharge coke may further comprise the steps:
Start the coke discharging device and discharge coke;
Coke is discharged meausring apparatus weighing coke discharge rate.
The step of said system calibration may further comprise the steps:
Detect the dried oven coke that puts out and whether reach correction material level position;
Calculated correction value;
