Abstract
The invention discloses a maintenance structure, particularly a carbonization chamber bottom brick integral-replacement hot-repair structure. The invention provides a carbonization chamber bottom brick integral-replacement hot-repair structure capable of thermal insulation for the carbonization chamber, which comprises a carbonization chamber main body composed of a top, a bottom and side walls, and a thermal insulation door and a brick delivery device, wherein the thermal insulation door is arranged at the inlet of the carbonization chamber main body; and a brick delivery space for the brick delivery device to pass through is left between the bottom side of the thermal insulation door and the bottom of the carbonization chamber main body. In the carbonization chamber maintenance process, the thermal insulation door is used for implementing thermal insulation for the carbonization chamber, thereby preventing the heat of the carbonization chamber from being quick emission, and implementing thermal insulation for the carbonization chamber; and thus, the great temperature difference of the carbonization chamber is avoided, thereby effectively prolonging the service life of the carbonization chamber. When mounting new high-alumina bricks, the special brick delivery device can be adopted, so that the brick mounting distance can be increased, so that all the bottom bricks can be replaced.
Description
Technical field
The present invention relates to a kind of maintaining structure, especially a kind of bottom brick of carbonization chamber integral replacing hot repair structure.In addition, the invention still further relates to a kind of method for maintaining, especially a kind of bottom brick of carbonization chamber integral replacing hot repair method.
Background technology
In current coking chamber maintenance, bottom brick of carbonization chamber of coke oven hot repair is local replacing, the longest less than 9m.Because coking chamber is longer, under hot repair state there is larger difficulty in integral replacing bottom brick of carbonization chamber, and workload is large, and temperature is high, adds that coking chamber is longer, send brick distance, and heap brick amount is large, is easy to faulting of slab ends.
In the maintenance process of coking chamber, must open the door of coking chamber, because the replacing time of bottom brick is longer, this stove overlong time that makes to have leisure, the temperature of coking chamber declines very fast; It is too fast that the overlong time of opening wide fire door causes temperature of furnace wall to reduce, and furnace wall rapid heat cycle causes silica brick damage efflorescence to degrade, and affects coke oven work-ing life.
Summary of the invention
It can be the bottom brick of carbonization chamber integral replacing hot repair structure of coking chamber insulation that technical problem to be solved by this invention is to provide a kind of.
The present invention solves the bottom brick of carbonization chamber integral replacing hot repair structure that its technical problem adopts, comprise the coking chamber main body being formed by top, bottom and sidewall, also comprise heat insulation door and send brick equipment, described heat insulation door is arranged on the ingress of coking chamber main body, and that between the base of described heat insulation door and the bottom of coking chamber main body, leaves that feed brick equipment passes through send brick space.
Be further, describedly send brick equipment to comprise car body, wheel, send brick handle, brick pushing plate and push away brick handle, described wheel is arranged on the bottom of car body, the described brick handle that send is connected on car body, described brick pushing plate is arranged on car body and can moves along car body surface, described in push away brick handle and be connected with described brick pushing plate.
Further, described heat insulation door comprises door frame and thermal insulation layer, and described heat insulation door is arranged on the ingress of coking chamber main body, and described thermal insulation layer covers on door frame.
Further, described thermal insulation layer is ceramic fiber blanket.
In addition, another technical problem that will solve of the present invention is to provide a kind of bottom brick of carbonization chamber integral replacing hot repair method that can be coking chamber insulation.
The present invention also provides a kind of bottom brick of carbonization chamber integral replacing hot repair method, comprises the following steps:
A, in the ingress of coking chamber main body, set up heat insulation door, that between the bottom of heat insulation door and the bottom of coking chamber main body, leaves that feed brick equipment passes through send brick space;
B, processing high alumina brick preheating, configure refractory clay;
C, use rail steel are removed second-hand brick, cleaning bottom of carbonization chamber;
D, utilization are sent brick equipment the high alumina brick after preheating to be fed through to the bottom of coking chamber main body, and high alumina brick are laid on to the bottom of coking chamber main body;
E, to utilize refractory clay be that the high alumina brick grouting laying is plastered;
F, dismounting heat insulation door.
Be further, in D step, describedly send brick equipment to comprise car body, wheel, send brick handle, brick pushing plate and push away brick handle, described wheel is arranged on the bottom of car body, the described brick handle that send is connected on car body, described brick pushing plate is arranged on car body and can moves along car body surface, described in push away brick handle and be connected with described brick pushing plate; When carrying high alumina brick, utilize and send brick handle to control car body, make car body carry high alumina brick to the position of setting, then utilize to push away brick handle and control brick pushing plate motion, make high alumina brick slide and drop into the position of setting from car body.
Further, in C step, the direction of removing second-hand brick is: from cokery side to centre.
Further, in C step, after removing second-hand brick, the position that need build new brick at the bottom of coking chamber is purged totally with pressurized air, do not stay the grit that is greater than 5mm.
The invention has the beneficial effects as follows: when carrying out coking chamber maintenance, utilize heat insulation door to be incubated for coking chamber, thereby avoid the heat Quick diffusing of coking chamber, thereby be effectively coking chamber insulation, avoid coking chamber to occur the larger temperature difference, thereby effectively extend the work-ing life of coking chamber.When new high alumina brick is installed, can adopt the special-purpose brick equipment that send, the raising that this distance that makes to lay brick is strengthened, thus can change all bottom bricks.This send brick device fabrication material simple, light easy to use, bottom brick can be fixed, especially in hot situation, bottom brick directly fast can be delivered to coking chamber depths, deliver to behind predetermined position, touch and send brick device push rod, bottom brick steadily can be placed and be formulated position, avoided using conventional instrument to send easily causing in brick process bottom brick to topple over or crooked need send the brick could success repeatedly back and forth several times, cause bottom not steady, brickwork joint faulting of slab ends, even causes operation unsuccessfully to need repair for 2nd time.
