Description

FIELD OF THE INVENTION [0001] The present invention relates to a smoke-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a smoke sleeve apparatus and method for preventing deflection of a coal, and more particularly, And to prevent falling of coal from falling down to the rear side of the hopper.

In general, as shown in FIG. 1, the extruder 20 located at a predetermined distance from the coke oven 10 is moved along the running rail in the longitudinal direction to align the center of the extruder 20 in a predetermined position, (leveling) start signal. The leveler door 60 of the carbonization chamber 50 is opened by the extruder leveler system 40 and then the front end of the smoke sleeve 40a is advanced to the inside of the coke oven 10 frame. Thereafter, while the wire rope 40b connected to the front and rear side of the leveler is wound around the drum 40c and unwound, a repetitive operation is repeated a predetermined number of times, for example, four times. Accordingly, the leveler bar 40d has a structure for performing the flattening work of the loaded coal.

At this time, coal is accumulated in the extruder hopper 50 at the time of flat work, and the stored coal is moved upward by a flow conveyor (not shown), dropped to the end portion of the smoke sleeve 40a, When the beam advances, the falled coal also enters the inside of the coke oven 10.

Meanwhile, the smoke sleeve serves as a pedestal when the coal stored in the hopper 50 is put into the coke oven by the flow conveyor. The specific structure and operation of the apparatus will be described with reference to FIG.

As shown in FIG. 2, the smoke sleeve is used to transport the coal stored in the hopper 50 using the front end 2 entering the coke oven 10 and the flow conveyor, And a hydraulic cylinder 4 that provides a driving force to move the rear end 3 and the smoke sleeve 40a forward and rearward, which serve as a pedestal when they are inserted into the vehicle.

Fig. 2 (a) is an operating state when the smoke sleeve 40a advances in the coke oven direction, and Fig. 2 (b) is an operating state when the smoke sleeve 40b is reversed.

Meanwhile, the problem that the coal inside the hopper is biased by such a conventional smoke sleeve will be described with reference to FIG.

3, the leveler beam 60 is retracted and at the same time the coal drawn off from the coke oven falls to the end 3 after the smoke sleeve, at which time the rear end 3 of the smoke sleeve is shown The coal is moved along the inclined surface, and then falls down in a backward direction inside the hopper installed in the lower portion.

The coal is prevented from flowing naturally to the flow conveyor 70 connected to the hopper 50 due to the falling of the biased coal, and thus the coal is accumulated and fixed in the hopper 50 in the past.

Further, since coal is added with moisture and tar, it is difficult to smoothly flow from the hopper 50 toward the flow conveyor 70, so that the coal is overflowed out of the hopper 50, or due to the position of the deflected coal and the fixed coal, Causing the inconvenience of rotation of the drum 70 and throwing the coal into the floor.

Accordingly, the present invention prevents the problem of falling coal behind the extruder hopper 50 during the leveling operation and induces the coal to drop to the center of the hopper 50, And it is an object of the present invention to provide a smoke sleeve apparatus and a method of preventing such a drop.
