Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a receiving device for receiving red-hot coke discharged from a coke oven for dry coke digestion.

[Conventional technology]

In coke dry extinguishing equipment, the red-hot coke discharged from the coke oven from the kiln is received by a coke bucket placed on a bucket truck that runs on rails, and transported to the hoisting tower by the bucket truck.The coke bucket is then hoisted up by a crane and placed in the dry extinguishing equipment. The red-hot coke is transported to the pre-chamber, the coke discharge gate installed at the bottom of the coke bucket is opened, and the red-hot coke is charged into the pre-chamber.The sensible heat of the red-hot coke is extinguished in the dry extinguishing equipment and is then used to generate steam for power generation in a boiler, for example. After the red-hot coke has been discharged, the coke bucket is loaded onto the bucket truck again to prepare for the next discharge from the coke oven.

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

[Problem that the invention attempts to solve]

Conventional coke buckets are rectangular and are placed on a bucket truck so as not to rotate, and the red hot coke discharged from the coke oven is pushed out towards the oven side of the bucket, so it is concentrated in the bucket. Therefore, the effective volume ratio of the coke loaded in the tower to the total volume of the coke bucket was extremely low.

In order to solve this problem, an apparatus has been proposed in which a turntable is provided on a coke bucket truck, the coke bucket is placed on the turntable, and the coke bucket is rotated to receive the coke.

However, depending on the layout of the dry fire extinguishing equipment, the coke bucket containing red-hot coke is moved horizontally, for example, at right angles to the coke oven, hoisted up by a crane, and the gate of the coke bucket is opened on the pre-chamber. Some systems charge red-hot coke into a pre-chamber.
In order to do this, the bucket cart must be moved laterally from the top of the cart. Conventional wreckage devices can rotate the coke bucket cart, but devices that can move the coke bucket cart laterally with respect to the cart Nakatsuta.

[Means for solving problems]

In order to solve the above problems, this invention uses a parent-child type bucket truck with a child truck placed on the parent truck, and a saucer for placing the coke bucket on the child truck is rotatably attached. A pair of left and right guide plates are provided in parallel at regular intervals on both sides of the center of the saucer, and both guide plates protrude downward from an opening in the center of the child truck, and protrude from the center of the upper part of the parent truck. The rotating shaft is provided with a turning arm that is inserted between the guide plates at the bottom of the tray and rotates the tray, and driving means for the rotating shaft is provided on the parent truck, and a rotating arm is provided at both ends of the parent truck. A guide rail is provided in a lateral direction perpendicular to the running direction of the parent truck, and the lower wheels at both ends of the child truck are mounted on this guide rail.
