Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is for dry extinguishing of coke in a coke oven.
- This invention relates to a red-hot coke receiving device used in a coke oven.

(Prior art) = In an r-x dry fire extinguishing system, red-hot coke discharged from a coke oven is received by a coke bucket placed on a bucket truck running on rails, and transported to a hoisting tower by the bucket truck. After that, the coke bucket is hoisted up by a crane and transported to the pre-chamber of the dry fire extinguishing equipment, the coke discharge valve (ff-) installed at the bottom of the coke bucket is opened and the red-hot coke is charged into the pre-chamber, and the red-hot coke is discharged. is extinguished using dry extinguishing equipment, and the sensible heat of the red-hot coke is effectively used within the system, for example, to obtain steam for power generation at the dealership.However, after the red-hot coke has been discharged, the coke bucket is placed on the bucket truck again. Prepare the coke oven for the next kiln discharge.

Thus, the coke bucket, together with the bucket truck, is a conveying device that is repeatedly used for conveying red-hot coke.

(Problems to be solved by the invention) The conventional coke bucket and bucket truck are shown in Fig. 4 (1).
And as shown in FIG. 4(b), there is a rectangular coke receiving plate 22 on the bucket truck 1, and nine rectangular coke buckets 23.
It is loaded with a coke oven 4 and is pulled by a train 31 and stopped at a fixed position at the coke oven kiln mouth before discharge from the oven, and the coke 25 pushed out from the coke oven 4 through the coke guide is transported to the coke oven 4 with the effective length t of the bucket. Drive at low speed within the range and die.

However, in the existing coke oven, the coke falling point 26 is extremely close to the oven side, and due to the angle of repose 29 of the red-hot coke, the coke 25 after being buried is as shown in Figs. 5(a) and 5(b).
) As shown in the packing diagram, the coke was biased toward the furnace side, and the effective coke volume ratio to the total volume of the coke bucket 23 was extremely low.

In addition, as is clear from the packing diagram, an uneven load occurs, and it is necessary to provide a balance weight on the side of the coke bucket 23 opposite to the coke oven in order to maintain balance when hoisting it with a crane at the hoisting base. As a result, there was an inconvenience that the coke, gas, and torsion became heavy.
