Dismounting and removing work for brick of hot air furnace
专利汇可以提供Dismounting and removing work for brick of hot air furnace专利检索，专利查询，专利分析的服务。并且PURPOSE: To effectively dismount and remove the bricks of a hot air furnace without damaging the iron shell of side walls and the side walls by a method in which bricks laid in staggering joint are broken and discharged from an opening drilled through iron sheaths in the side walls of the furnace and the bricks deposited inside the furnace are used as scafold.
CONSTITUTION: A gate 5 is provided in an opening 4 drilled through an iron shell 2 at the lower part of the wall of a hot air furnace 1, and explosives 13 are charged from the bottom of the furnace in necessary places other than the vent hole 10 of bricks 9 laid in staggering joint in the lower part and allowed to explode in such a way as to break nearly all bricks 9 and 12. The broken bricks are partly discharged from the gate 5 but mostly deposited up to an upper level 14. Then, a scafolding 15 is placed on the upper level 14 as needed, and a worker goes into the furnace 1 from an upper manhole 11 to charge explosives from the scafold plate 15 to the upper side wall 3 and explode them. Then, the gate 5 is opened, the upper level 14 is settled down to the next exploding work level, the gate 5 is closed, and exploding work is performed. The same operations are repeate to complete the dismounting and removing work of the bricks of the side wall 3 and the partition wall 16 inside the furnace.
