Description
Technical field
The utility model is related to coke oven door structure more particularly to a kind of energy-saving fire door lining brick of coke oven.
Background technology
Currently, the fire door lining brick that the country of China uses is mostly based on cordierite brick.Cordierite brick has higher thermal shock steady
It is qualitative, but harmful substance is readily permeable to inside brick, reduces the physical property of brick, the cleaning of carbon causes fire door lining brick
Focal drug-block.In addition, above-mentioned furnace door brick size is smaller, building process is time-consuming and laborious；Once damage, it would be desirable to the long period into
Row is built by laying bricks or stones, and the normal production run of coal chemical enterprise is influenced.Coke oven solves the problems, such as removing tar and impermeabilisation with fire door glazed tile,
But fail to reduce the surface temperature of fire door.Therefore existing there is an urgent need to once be upgraded to fire door lining brick of coke oven, reduction is transformed into
This.Coke quality is improved, fire door service life is extended, the convenient labor intensity safeguarded, reduce worker's fire door cleaning fire door plays
Volume increase section consumption, the purpose of environmentally friendly synergy.
Chinese patent ZL200720066233.7 discloses a kind of coke oven door structure, it is fireproof prefabricated using polylith large size
Block, every piece large-scale refractory precast block are mounted on by least two bolts on the inside of firedoor frame shell, refractory brick, firedoor frame and carbonization chamber
Two triangular spaces in left and right are formed between furnace wall, form raw coke oven gas passing away.The characteristics of patent is to use large scale prefabricated piece
Instead of original fritter refractory brick, reduce brickwork joint, and has raw coke oven gas passing away.But without using glaze structure is applied, still having
Tar penetrates into inside lining brick, and it is inconvenient to safeguard, worker's fire door decarbonizing labor intensity reduces unobvious, does not also reduce significantly
Fire door surface temperature effect.
Chinese patent ZL200620091980.1 and ZL200720016156.4 disclose a kind of coke oven door structure, all adopt
With the horseshoe-shaped large-scale lining brick containing glaze, patent ZL200620091980.1 uses bulk heat-insulated inside shape of a hoof brick
Material pours into heat-insulated pour mass in slot, and the method can reduce overall fire door weight, and heat insulation also has enhancing, glaze
Tar not easy to hang, but two kinds of materials are at high temperature since different expansion rates easy to produce separation, also without fastening bolt and fire door
Frame web is connected；Patent ZL200720016156.4 is upgraded, and does not use the structure of the heat-insulated pour mass filling of bulk, and
Increase fastener constructions in inside, but fastener constructions are not inside brick and brick is thinned brick surface temperature inside hollow structure and increases
Height causes fastener constructions intensity low, influences service life；Shape of a hoof brick is also easy to produce strong convection heat transfer, drop through inside configuration
Low heat insulation.
Invention content
