2. Description of the Related Art An example of a coke charging device of this type is disclosed in German Patent Publication No. 255.
No. 3386. In the conventional coke charging device, when the red hot coke was charged into the cooling shaft, coke particle size segregation occurred in the cooling shaft and the internal gas drifted undesirably.

Further, in a general coke charging device, a movable hopper which can be moved up and down is arranged so as to be movable laterally on a common table together with a cooling shaft gate which opens and closes an opening of the cooling shaft. .. Therefore, the installation of the device requires a relatively large space. Further, such a coke charging device contained dust ash inside the stationary hopper, especially while moving the cooling shaft gate from its closed position and laterally moving the mobile hopper. There is a risk of gas leaking into the atmosphere. Therefore, a means is needed to prevent this leakage until the cooling shaft gate returns to the closed position.

In order to solve the above problems, it is an object of the present invention to simplify the procedure for closing the moving hopper and improve the coke particle size distribution in the cooling shaft and the gas flow distribution through the coke packed bed. The object of the present invention is to provide a coke charging device having a simple structure capable of considerably reducing the emission of dust.

As described above, according to the present invention, the distribution cone supported by either the fixed hopper or the movable hopper appropriately distributes the reddish coke into the cooling shaft and segregates the coke particle size. Since it is configured to prevent the above, the flow distribution of the gas passing through the coke packed bed is improved. In addition, the gap between the mobile hopper or cooling shaft gate and the cooling shaft is defined by the first annular sealing element of the mobile hopper or the second annular sealing element of the cooling shaft gate.
Since the ring-shaped sealing element and the corresponding sealing means provided on the top of the shaft of the cooling shaft cooperate with each other to seal the structure, the simple structure prevents the emission of dust ash into the ambient atmosphere. Becomes
