Description
Technical field
The invention belongs to coke oven machine field, more specifically, relate to a kind of coke oven machine furnace door sealing device.
Background technology
Coke oven machine oven door sealing, mainly by the rigid contact between knife-edge and firedoor frame, occurs between knife-edge and firedoor frame
Gap, will be poorly sealed, occurs to run cigarette and burns with anger, and severe contamination site environment aggravates furnace retaining ironware simultaneously and damages.At present, burnt
The commonly used Z-shaped knife-edge of stove machine, its initial stage sealing effectiveness is good.As coke oven machine increases service life, firedoor frame deformation increases,
Knife-edge and firedoor frame seal and are gradually deteriorated, and to finally regulating, cause and seriously smolder.The assembling of Z-type knife-edge need to use hot charging work
Skill is to reach interference fit, and general fire door overhaul stand does not possess this condition.The Z-type knife-edge easily problems such as cracking, deformation,
The use cycle is short, it is frequent to repair, spare parts consumption is big.The gap of Z-type knife-edge and oven door body junction easily smolders, it is impossible to ensure
Sealing effectiveness.The knife-edge mouth of Z-type knife-edge is little with knife-edge fixing point size cantilever, and regulation rigidity is big, and governor motion efficiency is low, works as cutter
When having larger gap between limit and stove frame, it is impossible to regulation puts in place.The Z-type knife-edge life-span is short in view of the above, sealing effectiveness difference and tune
The shortcomings such as joint amplitude is little, it is impossible to meet actual coke oven machine field needs.
