Intelligent gate-type coke feeder and control method

Abstract

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.

Description

technical field [0001] The invention relates to a coke platform coke unwinding machine used for wet coke quenching in a coking plant and a control method. Background technique [0002] At present, the process of wet coke quenching in coking plants is as follows: through coke pusher and coke blocker, high-temperature coke is loaded into the coke quenching car, and moved to the coke quenching tower, and the water spraying coke quenching system in the coke quenching tower Cool the coke. Then put the quenched coke on the coke platform by the coke quenching car. The role of the coke table is to cool the mixed coke after wet quenching, drain water, evaporate water, and supplement the quenching of the remaining red coke. Normally, the cooling time of coke on the coke table is about 30 minutes. Under the coke platform, mechanized coke is used, and the mixed coke that slides down from the coke platform is evenly scraped to the coke transport belt conveyor in the trench of the coke...

AI Technical Summary

Problems solved by technology

The focusing process requires manual observation and control by the operator. The coke on the coke table requires the operator to record the focusing sequence of each section and record the focusing time; the focusing amount of the focusing machine will not be adjusted according to the actual situation; the degree of automation Low, in the harsh on-site environment, the entire focusing process requires multiple operators to perform control operations, and the labor intensity of the operators is high
