The invention relates to a
coke feeder for a
coke bench used for wet
quenching in a
coking plant and a control method for the
coke feeder, in particular to an intelligent gate-type coke feeder. The intelligent gate-type coke feeder comprises a variable frequency motor, eccentric cranks, a brace, a plurality of reciprocating open
doors with flexible guide rolls, wherein the brace adopts a structure with independent segments; the reciprocating open
doors are arranged on the brace at intervals; each segment of the brace is connected with the variable frequency motor through an eccentric
crank matched with the segment of the brace; the variable frequency motor drives the segment of the brace to move; a material detection device is arranged in a unit area of the coke bench; a plurality of cokeplacing positioning devices are arranged near a rail of a coke
quenching vehicle; an electronic scale is arranged on the
belt conveyor; and the material detection device, the coke placing positioningdevices, the electronic scale and the variable frequency motor are communicated with the PLC (
Programmable Logic Controller)
control system respectively. The method has the advantages that the degreeof
automation is high; the automatic positioning of the coke
quenching vehicle on the coke bench, the
automatic control of
delay coke feeding and the coke feeding quantity as well as unmanned operation can be realized; and the coke feeding quantity can be controlled effectively, so as to ensure uniform, safe and reliable coke feeding of a
system.
