JPS5891788A - Apparatus for charging compacted raw coal briquette into coke oven - Google Patents

Abstract

PURPOSE:To surely charge the compacted raw coal briquette into a coke oven without tearing down its shape, by charging the briquettes together with a container bottom plate into the coke oven, and pulling out only the container bottom plate while holding the briquette. CONSTITUTION:The compacted raw coal briquette M is charged in a container N. The container N together with its frame N1 and its bottom plate N2 is placed on an elevating plate 14. Then the elevating plate is descended to support the frame N1 on a side plate and the bottom plate N2 on a roller 13. After a traveling truck 1 is moved in the direction of an arrow A or B, the truck is stopped at a position where a container bottom plate transferring passage 11 is met with the briquette charging port 5 of a coke oven 4. A sprocket 21 is clockwise rotated to move a container-driving plate 19 in a direction C and to introduce the bottom plate N2 and the briquette M placed thereon into the coke oven 4. Then while holding the briquette M by moving a briquette holding plate 27, the sprocket 21 is counterclockwise rotated to move the driving plate 19 and the bottom plate N2 in a direction D, and to pull out them. Since the briquette M is held by the holding plate 27, the briquette remains in the oven 4 while maintaining its shape.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a charging device yt- for charging into a coke oven a coking coal compacted cake made up of a plurality of coking coal compacted blocks that are packed in a container and transported.
