The present invention relates to an apparatus for preventing the emission coke of dry fire extinguishing equipment, and in particular, to minimize the drop impact of the coke discharged after cooling to increase the particle size of the coke, and to prevent the wear and damage of the equipment.

In general, coke at 1,000 to 1,100 ° C extruded from a coke oven is temporarily stored in a prechamber (1) of a dry fire extinguishing facility, as shown in FIG. 1, and then moved to a cooling chamber (2), where The cooled coke is discharged at regular intervals through the coke discharger (3).

The coke falling through the discharger (3) is guided by the hopper-shaped guide plate (4) is supplied to the lock hopper (Lock Hopper; 5) is loaded on the transport belt of the lower it is transported to a predetermined place Same as

However, in the related art, since the coke passing through the ejector 3 falls directly collides with the guide plate 4, the coke is crushed and differentiated, and the coke particle size is reduced, and the guide plate 4 is caused by the collision of the coke. The problem of premature wear is noted.

In order to prevent premature wear of the guide plate 4, the use of expensive wear-resistant materials is in fact the most appropriate countermeasure, but in this case, the wear may be delayed to some extent, but the wear itself may not be fundamentally prevented. As a result, periodic maintenance work is required and expensive materials are used. As a result, the original purpose of preventing wear is lost.

The present invention has a purpose to provide a discharge coke differentiation preventing device of the dry fire extinguishing equipment that can actively solve the above problems, in the following by the accompanying drawings a preferred embodiment of the present invention to effectively achieve the above object. It explains in detail.

According to the present invention, as shown in FIG. 2, an impact preventing plate 7 is provided on both sides of the lower end of the discharger 3 to reduce the drop width of the coke, and the differentiation in which the coke is accommodated in the guide plate 4 below the discharger 3 is provided. It was made by installing the prevention plate 8.

In the figure, reference numeral 7a denotes a reinforcing plate, and 9 denotes an inert gas outlet.

The fixed coke is welded to the lower end of the discharger (3), and the discharged coke accumulates a certain amount on the upper surface of the impact preventing plate (7), so that only the overflowed coke (C) falls to the guide plate (4) side, and the heat of the coke (C) or In order to prevent deformation by load, the reinforcement board 7a is welded and fixed in the several places between the impact prevention board 7 and the ejector 3.

Further, the coke C falling from the impact preventing plate 7 is accommodated between the guide plate 4 and the differentiation preventing plate 8 as shown in FIG. 4, and the coke C falling in such a state is made of metal. Since the collision with the coke (C) accommodated between the guide plate 4 and the anti-differential plate 8 without directly colliding with the guide plate 4, the crushing or differentiation of the coke (C) is effectively prevented and at the same time Wear is also actively prevented.

As can be seen from Table 1, according to the present invention, the drop of coke (C) is significantly reduced by the impact preventing plate (7) to obtain the effect of improving the particle size by preventing the breakage of the coke (C), the toilet paper The plate 8 prevents the differentiation of the Cocos (C) and the wear of the guide plate (4), thereby increasing the yield of Cocos (C), preventing damage to the equipment, and improving the operation rate of the coke oven and high service life. A wide range of effects, such as extending, can be obtained.
