Abstract
A two-layer knife edge coke stove door relates to the coal-chemical field, in particular to a dual-knife-edge stove door for enclosing the coke stove. The utility model is designed to solve the matching problem of knife edge and stove frame, to promote airtightness of coke stove, to eliminate smoke and fire escaping from the stove, and to decrease labor intensity for coke stove operator. The stove door comprises an iron slot, a knife edge seat, a fastening bolt, two-layer knife edge and stove frame, the upper section of the two-layer knife edge extending into the knife edge seat while the lower section being provided with groove to form the dual knife edge structure, the two-layer knife edge being in match with the stove frame, the knife edge seat being fixed with the iron slot by the bolt. As indicated by the contrast test performed by retrofitting the existing stove door, airtightness is improved greatly, fire and smoke escaping from the stove are completely eliminated, lifetime is prolonged; furthermore, the structure is simple.
Description
Technical field
The utility model relates to coal chemical technology, specifically a kind of fire door that is used to seal the double-pole limit structure of pit kiln.
Background technology
Before the utility model proposes, the sealing of traditional coke furnace door is that the hilted broadsword limit by fire door metal trough edge contacts with pit kiln stove frame and realizes sealing, but because the blade thickness that adopts the A3 steel band to make has only 5mm, thickness of knife edge 2-3mm, this band knife-edge structure fire door is through long high temperature and use, edge strength reduces, be easy to occur rolled edge deformity, make the face adapted of knife-edge and stove frame produce roughness, in case this situation occurs, fire door will produce the phenomenon of burning with anger of smoldering, the Working environment that it not only pollutes, and the while has also increased operator's labour intensity.Chinese patent CN2578333Y discloses a kind of knife-edge positioning adjustment device of cokery cokery side fire door, and it is attempted by realizing the elasticity location of knife-edge, and the elasticity adjustment solves the roughness problem between knife-edge and stove frame, with the good sealing effectiveness of degree of reaching.But the device of this whippy structure, it still adopts adjustment of hilted broadsword limit and stove frame to reach the ideal planeness.But we are not difficult to find in actually operating, this structure setting device, and its complex structure, regulating spring is owing to be subjected to the tired or fracture of the as easy as rolling off a log generation of temperatures involved for a long time, and improvement cost is also higher.
Summary of the invention
The purpose of this utility model provides the coking door of a kind of double-pole limit structure to solve the adaptive problem between knife-edge and stove frame, improves the coking door stopping property, eliminates the phenomenon of burning with anger of smoldering of coking door, improves oven coke operator's labour intensity.
In order to realize the purpose of this utility model, the contriver has proposed a kind of coke oven door with double-deck knife-edge, this fire door comprises the fire door metal trough, knife-edge deck, holding bolt, double-deck knife-edge of fire door and stove frame are formed, the upper section of the double-deck knife-edge of described fire door extends in the knife-edge draw-in groove, and double-deck knife-edge lower section offers groove, makes it to form double-pole limit structure, it and stove frame are adaptive, and the knife-edge deck is fastenedly connected by bolt and fire door metal trough.
In order further to ensure the stopping property of double-deck knife-edge and stove frame, the contriver has also filled resistant to elevated temperatures asbestos material in the groove between double-deck knife-edge, and the asbestos material of filling slightly exceeds knife-edge cross section 1-2mm, the asbestos of filling under the pressure of fire door locking can tighten, promptly guaranteed the planeness between knife-edge and stove frame, making again has good suitability between the two.Because asbestos material has resistant to elevated temperatures characteristic and its distinctive flexibility, make the stopping property of knife-edge and stove frame get enough assurance.
The double-deck knife-edge structure that the utility model proposes, simultaneous test through the existing fire door of repacking proves, the stopping property of its fire door is greatly improved, overcome the phenomenon of burning with anger of smoldering that coking door can occur fully under the long-term operation condition, strengthened fire door work-ing life, and simple in structure, the repacking cost is low, economical and practical.
Description of drawings
The structural representation of the double-deck knife-edge fire door of Fig. 1.
Fig. 2 double-pole limit structure sectional view.
Among the figure, fire door metal trough 1, holding bolt 2, knife-edge deck 3, double-pole limit 4, stove frame 5, weighting material 6.
Embodiment
The double-deck knife-edge of the utility model coking door adopts the A3 strip material, blade 8-12mm is thick, and 3-4mm is thick for the individual layer twolip, fills resistant to elevated temperatures asbestos material in the groove between the double-pole limit, asbestos can be made into asbestos strip and are entrenched in the groove, and the thickness of weighting material asbestos slightly exceeds knife-edge cutting plane 1-2mm.Because the both sides blade and between them the asbestos material in the groove form two hard one soft three-layer sealed structures, its sealing property and reliability have obtained actual guarantee.The packing material of groove between the double-pole limit also can consider to use resistant to elevated temperatures other flexible material, for example: lead, tin etc. in addition.The utility model is thoroughly eliminated hilted broadsword limit wiredrawn edge, the difficult problem that fire door is smoldered and burned with anger.
Claims (2)
1, a kind of coke oven door with double-deck knife-edge, it comprises the fire door metal trough, the knife-edge deck, holding bolt, double-deck knife-edge of fire door and stove frame are formed, and it is characterized in that the upper section of the double-deck knife-edge of described fire door extends in the knife-edge draw-in groove, double-deck knife-edge lower section offers groove, make it to form double-pole limit structure, it and stove frame are adaptive, and the knife-edge deck is fastenedly connected by bolt and fire door metal trough.
2, a kind of coke oven door with double-deck knife-edge according to claim 1 is characterized in that having filled resistant to elevated temperatures asbestos material in the groove between described double-deck knife-edge, and the asbestos material of filling slightly exceeds knife-edge cross section 1-2mm.
