Abstract
Burning furnace is baked over a slow fire with energy -conserving fire handhole door to open -type ring type, including top layer fire handhole door, bottom fire handhole door and pouring material apron, two -layer seal structure about top layer fire handhole door and bottom fire handhole door form, top layer fire handhole door passes through the sealed face joint of tapering in the pouring material apron top of bottom, bottom fire handhole door sets up in pouring material apron lower part through the sealed face of tapering on surface, the adoption is excelled in to pour into a mould and is expected that the granule is the aggregate, high -temperature glue mud combines the vibration for the binder, form through 1200 DEG C of high -sintering preparation again. The utility model discloses the fire handhole door uses and excels in pouring material granule as the aggregate, high -temperature glue mud for the binder combine the vibration adopt about two -layer sealed double -deck seal structure, sealed face adopts a double -deck tapering sealed, and is sealed effectual, has reduced the emission that calcination natural cooling in -process baked the interior residual gas of burning furnace over a slow fire, has reduced production of a large amount of carbon dioxide and sulfur dioxide and exhaust emission.
Description
Technical field
This utility model relates to calcining carbon equipment technical field, is specifically related to a kind of open-type ring-type roasting furnace energy-saving fire port lid。
Background technology
Calcining carbon be by molding after raw product in roaster, under the protection of inserts completely cut off air carry out high-temperature heat treatment。Fire hole cover is a kind of assembly of roaster, the Main Function of fire hole cover: seal, it is prevented that cold air enters affects the intensification of whole combustion system in roaster；Insulation, reduces fire hole cover heat radiation and gas consumption, heat energy loss。The roasting requirement to fire hole cover: good sealing effect in roasting temperature process, heat dissipation capacity is little；At high temperature do not ftracture。
The commonly used cast iron fire hole cover monolayer of current domestic open roasting furnace, stiff dough seal, and owing to easily shrinking under cast iron fire hole cover high temperature, deforming, thermal losses is big。Fire hole cover sealing effectiveness after contraction, stiff dough sealing and deformation is bad, and with formation gap, roaster fire hole place, stove negative pressure reduces, and heat loss is bigger。Because sealing effectiveness is bad, after Temperature fall process combustion of natural gas, the gas of residual is discharged to roasting boiler face below fire hole cover, creates great amount of carbon dioxide greenhouse gas。
Utility model content
This utility model provides a kind of open-type ring-type roasting furnace energy-saving fire port lid, and the sealing effectiveness difference existed to solve prior art causes the problem that heat loss is relatively big and produces a large amount of greenhouse gases。
This utility model solves its technical problem and be the technical scheme is that
A kind of open-type ring-type roasting furnace energy-saving fire port lid, including top layer fire hole cover, bottom fire hole cover and castable cover plate, top layer fire hole cover and bottom fire hole cover form upper and lower two-layer and seal structure, top layer fire hole cover is connected in castable cover plate top by the taper sealing face of bottom, and bottom fire hole cover is arranged on castable cover plate bottom by the taper sealing face on surface。
Above-mentioned top layer fire hole cover top and bottom fire hole cover top are respectively provided with a hook drop handle。
The preparation method of above-mentioned open-type ring-type roasting furnace energy-saving fire port lid, adopting high-strength castable granule is aggregate, high temperature clay is that binding agent forms in conjunction with vibration, it is respectively prepared top layer fire hole cover, bottom fire hole cover and castable cover plate, then top layer fire hole cover, bottom fire hole cover and castable cover plate is made through 1200 DEG C of high temperature sinterings in tunnel cave。
The aluminium sesquioxide mass content of the above-mentioned fire hole cover made is not less than 60%, and the fire hole cover bulk density made is not less than 2.35g/cm3, and in the fire hole cover made, steel fibre mass content is 5%。
This utility model fire hole cover is with high-strength castable granule for aggregate, high temperature clay is that binding agent combines vibration employing upper and lower two-layer sealing double-layer sealing structure, sealing surface adopts double-deck taper sealing, good sealing effect, reduce the discharge of residual gas in roaster in roasting natural cooling process, decrease great amount of carbon dioxide and sulfur dioxide produces and exhaust emission。
Accompanying drawing illustrates:
Below in conjunction with drawings and Examples, this utility model is further illustrated。
Fig. 1 is the structural representation of this utility model device。
1 top layer fire hole cover, 2 bottom fire hole covers, 3 castable cover plates, 4 taper sealing faces, 5 hook drop handles in figure。
Detailed description of the invention:
As shown in the figure, a kind of open-type ring-type roasting furnace energy-saving fire port lid, including top layer fire hole cover 1, bottom fire hole cover 2 and castable cover plate 3, top layer fire hole cover 1 and bottom fire hole cover 2 form upper and lower two-layer and seal structure, top layer fire hole cover 1 is connected in castable cover plate 3 top by the taper sealing face 4 of bottom, bottom fire hole cover 2 is arranged on castable cover plate 3 bottom, top layer fire hole cover 1 top and bottom fire hole cover 2 top by the taper sealing face 4 on surface and is respectively provided with a hook drop handle 5。
The preparation method of above-mentioned open-type ring-type roasting furnace energy-saving fire port lid, adopting high-strength castable granule is aggregate, high temperature clay is that binding agent forms in conjunction with vibration, it is respectively prepared top layer fire hole cover, bottom fire hole cover and castable cover plate, then top layer fire hole cover, bottom fire hole cover and castable cover plate is made through 1200 DEG C of high temperature sinterings in tunnel cave。
The double-deck taper sealing of this utility model double-layer seal energy-saving fire port lid employing can reduce substantial amounts of cold air at roasting process and enter in roaster, can cancel the Polypropylence Sheet increasing the refractory fiber blanket sealed and top covering below former cast iron fire hole cover；Double-layer seal energy-saving fire port lid is lower than cast iron fire hole cover surface temperature about 150 DEG C in roasting process surface temperature, reduces substantial amounts of heat energy loss；Good sealing effect, heat energy loss are few, produce the low gas consumption of ton anode drop about 10 cubic metres。
The quality index of the fire hole cover that this utility model is made such as following table:
