During using, the heat-insulating protective shield used during the hot maintenance of the coke oven carbonization room, provided by the invention, can rapidly insulate high heat of the carbonization room, so that the maintenance cycle is shortened; the protective shield can be used for several times in a turnover manner, so that the maintenance cost is reduced.
Description
Technical field
The present invention relates to industrial furnace construction technology, the heat-insulated protective shield of more particularly, to a kind of coke furnace carbonization chamber hot repair.
Background technology
In the actual production process of coke oven, due to the air-flow punching in the even production process of fire resisting material of furnace body non-homogeneous expansion
Gap in brush, high-temp combustion, part brickwork joint and dilatation joint, or even there is fragment of brick fracture.In order to not affect to produce, need in heat
Under state environment, carbonization chamber metope breakage is keeped in repair or changed.In addition, fire door and the collision of firedoor frame long term mechanical, cause
Firedoor frame compression butterfly spring lost efficacy, and occurred smoldering, burns with anger (mainly at gib headed bolt) it is necessary to firedoor frame gib headed bolt and butterfly
Spring is changed.In maintenance process, carbonization chamber high temperature section (1500 degree) need to be kept apart, generally using building firebreak and laying by laying bricks or stones
Ceramic fiber blanket two ways.
Method one: firebreak form of construction work, first refractory brick polylith is banded together, be encased in charcoal from furnace roof hole of coalingging
Change room, after forming firebreak, paving ceramic fiber blanket on firebreak, the position that carbonization chamber is needed repairing separates, and waits to tie up
Repair end, ceramic fiber blanket and refractory brick are removed.The loss of the method resistance to material is big, and maintenance cycle is long, and heat-barrier material can not be secondary
Using.
Method two: laying ceramic fiber blanket mode, install first between hole and support, then paving pottery is fine on supporting
Dimension felt.The method, ceramic fiber blanket can cause to tear, collapse, block sternly, effect of heat insulation is poor, heat-insulated material because gravity tenesmus
Material turnover rate is not high.
Content of the invention
The technical problem to be solved in the present invention is for defect of the prior art, provides a kind of coke furnace carbonization chamber hot repair
Heat-insulated protective shield, using energy quick barrier carbonization chamber high temperature during this heat-insulated protective shield maintenance, shortens maintenance cycle, protective shield can be many
Secondary be used in turn, save maintenance cost, reduce heat-barrier material loss.
The technical solution adopted for the present invention to solve the technical problems is: a kind of heat-insulated protective shield of coke furnace carbonization chamber hot repair,
Including left and right girder, connecting cross beam and triangle base, described left and right girder is identical waveform girder, and described connecting cross beam is even
Connect at crest and the trough of left and right girder；
Connecting cross beam at described crest is provided with ceramic fibre rope and rope tightening device for fastening ceramic fiber blanket；
The middle and lower part of described left and right girder is provided with handrail, and described handrail is connected with multiple spaced transverse tubes, lowermost end
Transverse tube handrail bottom is connected with the bottom of left and right girder, formed triangle base.
By such scheme, described connecting cross beam and handrail are connected with steel pipe, the handrail end of steel pipe between the transverse tube of setting
The hole of termination is lifting hole；It has been horizontally disposed with fixture with lifting hole.
By such scheme, multiple shield segments of described left and right girder and the connecting cross beam heat-insulated protective shield of composition, described protection
Section is rectangle.
By such scheme, described girder is formed by steel-pipe welding, and the angle of the adjacent steel pipe of described girder is 60 degree to 150
Degree.
By such scheme, described triangle base has pulley.
By such scheme, the heat-insulated protective shield outer surface of described coke furnace carbonization chamber hot repair is coated with insulating moulding coating.
The beneficial effect comprise that:
1. when the heat-insulated protective shield of coke furnace carbonization chamber hot repair uses, the quick barrier carbonization chamber high temperature of energy, shortens maintenance cycle, protective shield
Can repeatedly be used in turn, save maintenance cost.
2. the wave structure of wave framework is ceramic fiber blanket segmentation stress, adopts ceramic fibre rope colligation further, makes
Ceramic fiber blanket is difficult tear, collapses.
3. the heat-insulated protective shield of coke furnace carbonization chamber hot repair and mobile hoistable platform combination application, heat-insulated protection is quick for installation.
