Description

[0001] The present invention relates to an emergency exhaust apparatus for coke fine bin,

The present invention relates to an emergency evacuation device for a coke pine bin provided in a blast furnace transportation facility.

More particularly, the present invention relates to an emergency discharging device for coke pine bin which prevents the conveyor belt from deflecting and preventing the coke from being burnt by making the coke discharged through the emergency chute balanced on the widthwise central portion of the conveyor belt.

Generally, the blast furnace operation is carried out by charging iron ores (sintered ores, pellets, sizing light) and coke from the top of the furnace and then blowing hot air from the bottom of the furnace, The molten iron and slag are produced by reduction melting.

In particular, the CPM (Coke Pre Mixing) operation is a process in which a medium sized heavy coke is charged through a separate path for the purpose of ensuring ventilation in the furnace by charging the coke of the medium, which is fuel, .

1, the coke stored in the coke oven 1 is screened in the screen 2, and the coke of the mass is charged into the blast furnace 3 through the conveyor belt, and the remaining coke is charged into the blast furnace 3, The coke is sent to the coke pine bin (4) through the conveyor belt.

The heavy and the minute coke stored in the coke oven bin 4 are sorted by the size of the cube em screen 5. The middle cube is transferred to the cube emitter 6 located at the distal end of the sintering light inlet line through the conveyor belt, Lt; / RTI >

At this time, in order to cope with various factors such as a case where the failure of the CPU 5 screen or a repair work occurs, the level of the CPU core 6 is decreased, the level of the coke-punched chip 4 is increased, The emergency chute 7 for emergency discharge from the conveyor belt is installed in the conveyor belt 4, but it is additionally installed in a narrow space, and the variation in the usage amount is large, causing various problems.

Particularly, as shown in Fig. 2, a so-called deflection phenomenon in which the conveyor belt (b) is pushed to one side during use of the emergency chute (7) and firebricks are generated and abnormal conveyance of the conveyor belt (b) Which is an essential operating requirement for blast furnace operation, is a direct cause of the instability of aging due to faulty balancing, resulting in lower productivity and various unstable influences.

When unstable phenomenon is analyzed by factors, basically, when a small amount of medium is discharged through the emergency chute 7, the vertical portion 7a of the emergency chute 7 normally moves the center portion o of the conveyor belt b The loading is performed. However, in the conventional emergency chute 7, since the inclination angle of the inclined portion 7b is gentle, the heavy meshes containing a large amount of water are difficult to be smoothly discharged.

In addition, when a large amount of heavy mass is discharged through the emergency chute 7, the inertial force of the heavy mass increases and the outer portion of the vertical portion 7a is worn out excessively, and the heavy mass is knitted on the conveyor belt (b) there is a problem that flame is generated due to the bending phenomenon of b).

In order to prevent this, as shown in FIG. 3, if a reinforcing block 8 having a crescent shape is provided outside the vertical portion 7a of the emergency chute 7, The stagnation and clogging phenomenon occurs and the inner surface of the vertical portion 7a is worn, so that the problem of knitting and flaming is not solved.

In order to solve the above-mentioned problem, there is a method of discharging a small amount of the middle mass. This is because it is difficult to maintain the proper level of the CPMP bin 6 for the CMP operation and thus it is difficult to maintain a stable aging period, It is inevitable to increase the discharge amount of the emergency chute because troubles such as troubles caused by an increase in the load of the coke conveyance belt for handling this are accompanied.

The bellows link member 330, which is an embodiment of the output opening adjustment member 300, includes an X-link 331 and a connecting link 333.

The X-link 331 is an x-shaped link in which a center O of the X-link 331 is pin-coupled to the support 310, and is capable of scissors movement about the center O. The connection link 333 is a pair of links that are coupled to each upper end of the X-link 331 and are coupled to slide along the guide slot 311 while overlapping the upper end.

Therefore, when the upper overlapping portion of the connecting link 333 is pulled upward, the upper ends of the X-link 331 connected to the lower end of the connecting link 333 are moved in a direction approaching each other, It is exercised. On the contrary, when the upper overlapping portion of the connection link 333 is pushed downward, the upper ends of the X-link 331 connected to the lower end of the link 331 are moved in a direction away from each other, and both lower ends are scissors moved away from each other.

The compression spring 350 which is a constitution of the output opening adjustment member 300 elastically connects the upper end of the connection link 333 and the center O of the X-link 331, The upper end of the connecting link 333 exerts a compressive elastic force in a direction in which the upper end of the connecting link 333 approaches the center O of the X-link 331.

The exit opening adjustment plate 370 which is a constitution of the exit opening adjustment member 300 is installed to penetrate both sides of the skirt box 9 while being coupled to both lower ends of the Xlink 331. Accordingly, the size of the outward opening of the emergency chute 7 can be adjusted as the distance between the lower ends of the X-link 331 is approximated or approximated by the scissors.

Here, a liner 372 made of a high-hardness material may be laminated on the upper surface of the pair of the outwardly-opening throttle plates 370 to prevent premature wear of the outwardly-opening throttle plate.

The pair of outwardly-opening adjustment plates 370 may be disposed symmetrically with respect to the widthwise center portion 9a of the conveyor belt 10. [ This is because the widthwise center portion 10a of the conveyor belt 10 is always positioned between the pair of outgoing opening adjustment plates 370 so that the heavy center is always loaded only in the widthwise middle portion of the conveying conveyor, So that it is possible to prevent the deflection phenomenon of the conveyor belt 10, which was one of the problems in the prior art,

Further, since the upper and the side surfaces of the outward opening control plate 370 are closed to prevent the falling of the light, the middle opening of the skirt box 9 is protruded through the through hole (through hole) It is preferable to provide a sealing rubber plate 9b for sealing the gap between the outgoing opening adjustment plate 370 and the through hole 9a of the skirt box 9 on the side surface of the skirt box 9 Do.

The interlocking member 400, which is an embodiment of the input side opening adjustment member 200, includes a first guide roller 410, a second guide roller 420, and a wire rope 430.

The connection link 333 is moved up and down along the guide slot 311 via the wire rope 430 in accordance with the upward and downward movement of the input side opening control plate 210, And the pin-connected X-link 331 performs scissors movement at the center O thereof.

Hereinafter, the operation of the present invention will be described (see FIGS. 5 and 6).

5, when the inlet opening regulating plate 210 is slightly raised by the driving cylinder 230, the connection link 333 is pulled upward by the wire rope 430. As shown in FIG. At the same time, the X-link 331, which is connected to the lower end of the connection link 333, is scissored with respect to the center O of the X-link 331, As a result, the interval between the pair of outward opening adjustment plates 370 assembled at the lower end of the X-link 331 becomes smaller than the initial state.

Accordingly, the distance between the outward opening adjustment throttling plates 370 is reduced in accordance with the slight increase of the opening regulating plate 210, so that it is possible to smoothly discharge the middle opening through the emergency chute 7, Since the middle block is loaded at the center in the width direction of the conveyor belt 10, deflection and flame retardation of the belt can be prevented.

6, the connection opening 333 is pulled upward by the wire rope 430 when the opening degree regulating plate 210 is greatly elevated by the driving cylinder 230. As shown in FIG. At the same time, the X-link 331, which is connected to the lower end of the connecting link 333 by the compressive elastic force of the compression spring 350, moves from the initial state to the lower end by scissoring with respect to the center O thereof. As a result, the distance between the pair of outward opening degree adjusting plates 370 assembled at the lower end of the X-link 331 is increased as opposed to the above case.

Accordingly, the interval between the outward opening adjustment throttling plates 370 is increased in accordance with the increase of the opening regulating plate 210, so that it is possible to smoothly discharge the middle opening through the emergency chute 7, The center of gravity of the conveyor belt 10 can be prevented from being deflected and burnt.

As described above, according to the present invention, since the coke discharged through the emergency chute is balancedly loaded in the widthwise central portion of the conveyor belt, it is possible to prevent the deflection of the conveyance belt and the firing of the coke, Since the angle is steep, it is possible to smoothly discharge the coke.
