Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、コークス炉用装炭車に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a coal loading car for a coke oven.
コークス炉用装炭車は、炉頂を走行し、所定の炭化室内
に石炭を装入するものである。A coal loading car for a coke oven runs on top of the furnace and charges coal into a predetermined carbonization chamber.
従来、装炭車は、第３図に示すように、炉頂ｌに設けら
れた石炭装入口２から炉内に石炭を装入するための内筒
３と、内筒３の周囲に設けられた、炉内への石炭装入時
、内筒３と石炭装入口２との隙間から石炭粉やガス等が
、炉外に流出するのを防止するためのスリーブ４とを備
えている。Conventionally, as shown in Fig. 3, a coal loading car has an inner cylinder 3 for charging coal into the furnace from a coal charging port 2 provided at the top of the furnace, and a cylinder installed around the inner cylinder 3. A sleeve 4 is provided to prevent coal powder, gas, etc. from flowing out of the furnace from the gap between the inner cylinder 3 and the coal charging port 2 when charging coal into the furnace.
しかしながら、石炭装入時、装炭車が所定の炉頂位置に
正確に停止するとは限らず、若干、内筒３と石炭装入口
２との位置が多少ずれることがあった。However, when charging coal, the coal loading car does not always stop accurately at a predetermined furnace top position, and the positions of the inner cylinder 3 and the coal charging port 2 may be slightly shifted.
このように、内筒３と石炭装入口２の位置がずれると、
同図に示すように、石炭粉５が石炭装入口２部分に堆積

口との隙間からの炉内ガスの流出量が増大する。また、
石炭装入口２部分に堆積した石炭粉５は、炉頂に散乱し
て、作業環境を悪化させていた。In this way, if the positions of the inner cylinder 3 and the coal charging port 2 shift,
As shown in the figure, coal powder 5 accumulates in the coal charging port 2, and the furnace lid for closing the coal charging port 2 is not correctly attached to the coal charging port 2 after the coal charging is completed. The amount of gas flowing out of the furnace from the gap between the lid and the coal charging port increases. Also,
Coal powder 5 deposited at the coal charging port 2 was scattered on the top of the furnace, deteriorating the working environment.
従って、この発明の目的は、石炭装入時、内筒と石炭装
