[0002] The elevator runs on the lifting derrick and the track on the top of the dry quenching furnace. It is one of the key equipment in the dry quenching system. It lifts the coke can filled with red coke and moves it horizontally to the top of the dry quenching furnace. It cooperates with the loading device to load the red coke into the dry quenching furnace. After loading the red coke, the empty can is lifted, moved and lowered to sit on the coke can trolley. The working principle of the elevator is: first, the coke can filled with red coke under the lifting tower is lifted to the top of the tower, and runs along the track to the dry quenching tower. After accurate alignment, the coke can is lowered to the top of the hopper of the coke loading device on the top of the dry quenching furnace. When the coke can slowly falls on the hopper, the gate at the bottom of the coke can automatically opens to load the red coke into the dry quenching furnace. When the red coke is loaded, the bottom door of the coke can is lifted to block the ash delay, and then the coke can is lifted to the upper limit. The elevator returns to the lifting tower along the track, lowers the empty coke can to the coke can trolley at the bottom of the tower, opens the hook, and prepares for the next work cycle.
