Description
Technical field
The present invention relates to a kind of refractory masonry method for dismounting, specifically, being that a kind of capacity coke oven ontology refractory masonry is fast
Fast method for dismounting.
Background technique
China has the capacity coke oven that more than 100 seats have been in the middle and later periods in furnace life at present.Over time, coke oven ontology
Masonry will increasingly aging, refractory brick badly broken；Furnace retaining ironware is broken, is poorly sealed with ontology masonry, leads to coke oven ontology
Large area, which is smoldered, in process of production burns with anger, and seriously affects production, environmental requirement is not achieved.And the original coal tower of coke oven, platform,
Coke oven base, resistance wall and furnace end stand are all intact, can continue to use.For save the cost, many coke-oven plants are using reservation institute
There is civil engineering position, remove coke oven ontology masonry, furnace retaining ironware and associated process equipment, then re-starts coke oven ontology masonry block
Furnace retaining ironware and associated process equipment are built and installed, coke oven is allowed to continue to put into production.Therefore it is badly in need of a kind of capacity coke oven sheet in the industry
The quick method for dismounting of body refractory masonry.
Summary of the invention
The purpose of the present invention is that proposing that one kind is safe and reliable removes refractory masonry, effective protection coke oven base platform, supports
The quick method for dismounting of capacity coke oven ontology refractory masonry of equipment under anti-wall, furnace.
To achieve the above object, the technical solution of the invention is as follows:
A kind of quick method for dismounting of capacity coke oven ontology refractory masonry, it is characterised in that the following steps are included:

Canopy-protected is carried out using several protection boards；To waste gas valve hole on flue using the wooden springboard canopy-protected, refractory brick is prevented
Fall to coke oven basement；It is blocked at the railing of coke side platform outer using waste and old pallet, prevents the refractory brick tumbled from falling into
On coke-quenching vehicle track；Burlap is filled up out of basement downward jet pipe, prevents brick slag in demolishing process from falling into blocking；
(2) coke oven door is won, coke oven door frame, furnace top equipment pipeline, pusher side and coke side platform, furnace retaining ironware are removed；
B, since oven top structure for coke oven load-bearing is limited, 2 mini-excavators are hung to oven top of coke oven with truck crane, using small-sized digging
Pick machine is removed from oven top of coke oven end stand and platform pusher side between middle coke oven, and oven top of coke oven and carbonization chamber are removed, and
Make a part filling for the useless refractory brick for first removing generation to coke furnace carbonization chamber, another part gives up refractory brick to coke oven machine side direction
It has bad luck, so that useless refractory brick is formed slope in coke oven machine side, after removing 10 hole of coke oven machine side refractory masonry so as to high-front shovel
Climb to operation on coke oven chute position；
C, high-front shovel is run on coke oven chute position by the slope starts to remove oven coke furnace roof, carbonization chamber
Operation, all useless refractory brick are had bad luck to coke oven machine side direction, the waste material dug out through coke oven machine side with being transported to coke oven machine side track
On face, transported to concentrate；
D, it using 2 large excavators, carries out removing coke oven chute and regenerative chamber, waste material from coke oven machine side both ends to coke oven coke side
It is discharged from coke oven machine side, excavating depth reserves subject to coke oven horizontal flue bottom；
E, coke oven horizontal flue bottom uses based on manual demolition, and form of construction work is removed supplemented by machinery, avoids machine in demolishing process
Tool and other tools destroy the screed-coat and both ends resistance wall of coke oven base platform；
F, coke oven furnace bed board, lower jet pipe are repaired in cleaning, the coke oven furnace bed board that partially there is crackle and expansion joint edge are destroyed, clearly
Then the brick slag sundries fallen into the clean seam of reason is reinforced grouting material filling with cement base and is restored, by the burlap in Coke oven lower spray pipe
It after taking down, is dredged with high pressure water, tar, sundries is cleaned out, the weight of coking furnace shaft refractory brick is carried out after the completion of cleaning
It is new to build work.
