JPS57108191A - Automatic controller for operation of dry coke quenching apparatus - Google Patents

Abstract

PURPOSE: To establish an unattended operation and automation of a dry coke quenching apparatus by automatically controlled hoist and travel of a crane, attachment and detachment of a coke oven cover, and opening and closing movement of a feeder in response to a process programmer.

CONSTITUTION: In response to a signal of recognition for stoppage at a predetermined position above a tower and a signal of completion of adjustment of a feeder chute, crane 1 starts lowering action at a low rate, which is accelerated at a position where the bottom of coke bucket 6 is to be opened. When the bucket is further lowered, its bottom is gradually opened and red-hot coke is taken into a cooling tower through a chute. The crane 1 stops with the bucket bottom being opened and starts hoisting at a time set by the process programmer. When the crane reaches the upper limit of the cooling tower, it travels back toward hoisting tower 7 and stops above the tower 7. In response to a signal of stoppage at a predetermined position above the hoisting tower 7, the crane starts a lowering action and stops at a position where the crane should wait after completion of one cycle.
