Description
Technical field
A kind of coke oven door knife-edge, more particularly to a kind of Novel coke oven door knife-edge are the utility model is related to, is belonged to
Carbonizing chamber of coke oven opening and closing device technical field.
Background technology
Two kinds of coke oven door extension set wing furnace door and coke side fire door, it is the equipment for opening and closing carbonizing chamber of coke oven Two-port netwerk.Work as fire door
During closing, carbonizing chamber and atmospheric isolation, pushing ram is able to release coke during opening.Whether tight the sealing of fire door is with preventing from emitting
Cigarette, burn with anger, environmental protection and firedoor frame, furnace stay deformation, failure close relation.Existing door structure is mainly by fire door
Configuration spring keeper, fire door peg on the outside of main body, inner side configuration web-type sealing knife-edge, slide plate, heat-insulated lining brick are built by laying bricks or stones in brick groove,
Surrounding configuration push type broach side spring seat assembly.Coke oven pushing car and coke guide are by operating fire door peg, biasing springs keeper, by stove
Door is suspended on firedoor frame, coke furnace carbonization chamber port shutdown；Fire door peg is hooked, biasing springs keeper, lifts and pulls out fire door,
Coke furnace carbonization chamber port open.To ensure sealing property, web-type knife-edge knife-edge framework and sheet metal flanging made of band steel
Manufactured web welding is integral, and by adjusting the pressure of the spring on the spring base of periphery, knife-edge is realized by depression bar transmission
With the sealing of firedoor frame.Big with knife-edge frame thickness difference because web material is thin-walled steel plate, weld seam is connected after welding
Intensity is difficult to ensure that, in coke oven production run, weld seam is also easy to produce part and snaps phenomenon, so as to cause to run cigarette, burn with anger, is influenceed close
Effect is sealed, pollutes environment, maintenance workload is big, have impact on the overall Environmental Protection Level of coke oven.In addition because of the operating mode temperature of use environment
Degree is high, and web is cooled, the interaction of thermal stress, easily deforms, and after deforming more than certain scope knife-edge frame will be caused to deform,
Cause run cigarette, burn with anger, influence sealing property, it is impossible to normal use and change, service life is short.Because web-type knife-edge is by knife
Frame and web carry out integral solder and formed, during replacing must integral replacing, spare parts consumption amount is big, and production run cost is high.
Utility model content
For drawbacks described above, the purpose of this utility model be to provide it is a kind of simple in construction, it is easily manufactured, it is easy to maintenance fast
A kind of prompt and durable reliable Novel coke oven door knife-edge.
Technical scheme is used by for this utility model：
Be provided with web including knife-edge framework made of band steel, in the knife-edge framework, the web surface be provided with it is some and
The bolt hole of fire door main body connection, the knife-edge framework lower end outer wall are provided with edge seal side, and the web surrounding lower surface is set
There is support plate, the support plate outer end is connected with knife-edge frame inner wall, and the web surrounding upper surface is provided with pressing plate, the supporting
Plate, pressing plate and web surrounding are bolted.
As the further improvement of above-mentioned technical proposal, the support plate outer end is connected with knife-edge framework using welding manner
Connect.
As the further improvement of above-mentioned technical proposal, it is provided between the web surrounding lower surface and support plate upper surface
Sealing gasket.
As the further improvement of above-mentioned technical proposal, gap is provided between the pressing plate outer end and knife-edge frame inner wall.
The utility model has the advantages that：
The utility model is simple in construction, and company is fixed to the web in knife-edge framework by using support plate and pressing plate
Connect, effectively avoid weld cracking, good airproof performance, do not run cigarette and durable reliable；Knife-edge framework and web can according to circumstances individually more
Change, replacing is convenient and swift, reduces operating cost and the labor intensity of worker.
