Abstract

The utility model particularly relates to a coke furnace door, which solves the problem that the adaption surface of a blade edge and a furnace frame in the prior coke furnace door is vulnerable to generate clearance. The coke furnace door comprises a circular blade edge and a furnace frame positioned at the periphery of furnace door bricks, wherein, a blade edge sheath is sleeved on the blade edge, two circular grooves are formed on the front end surface of the blade edge sheath, and steel wires equivalent in diameter are placed in the grooves respectively. In the utility model, a multi-layerseal structure designed between the blade edge sheath and the furnace frame of the coke furnace door ensures the tightness of the blade edge sheath and the furnace frame; and by injecting waste gasesinto the connecting pipe, a high pressure is produced and serves to prevent crude gases and tar produced inside the carbonization chamber from entering into the space defined by the blade edge sheathand the furnace frame and to seep through the adaption surface of the blade edge sheath and the furnace frame. Moreover, the utility model has the advantages of low cost, convenient disassembly, replacement and maintenance, etc.

Description

Coke furnace door

Technical field

The utility model relates to pit kiln, is specially a kind of coke furnace door.

Background technology

The sealing of traditional coke furnace door is that the knife-edge by coke furnace door metal trough edge contacts with pit kiln stove frame and realizes sealing, but because the thinner thickness of blade and blade, at high temperature use for a long time, the edge strength step-down, be easy to occur edge-curl phenomenon, and when near the lip-deep tar of stove frame the knife-edge is cleared up, be easy to blade is damaged, the face adapted injustice that causes knife-edge and stove frame, raw gas in the coking chamber leaks outside by the place, slit of knife-edge and stove frame, not only pollute to atmosphere, reduced the recovery of chemical products simultaneously, particularly during coking chamber is coaling, located as the slit of shutoff in time, fire door will produce the phenomenon of smoldering and burning with anger, when through after manually remedying, owing to coking chamber pressure inequality, long-time use also can cause knife-edge the gap to occur with the stove frame once more, not only further pollute Working environment, and increased working strength of workers.

Summary of the invention

The utility model easily produces the gap for the face adapted of the knife-edge that solves existing coke furnace door and stove frame and causes contaminate environment and increase the problem of labour intensity, and a kind of sealing effectiveness coke furnace door preferably is provided.

The utility model is to adopt following technical scheme to realize: coke furnace door, comprise the cyclic knife-edge and be positioned at furnace door brick stove frame all around, be with the knife-edge sheath on the knife-edge, have two cyclic grooves on the front end face of knife-edge sheath (contact surface of knife-edge sheath and stove frame), be placed with isometrical steel wire in each groove.Placed two isometrical Round Steel Wires on the knife-edge sheath, not only played the effect of double seal, and solved between original knife-edge and the stove frame because the knife-edge thinner thickness easily produces the problem in gap, it is low to have cost simultaneously, advantage such as changes, easy to maintenance.

The rear end of knife-edge sheath inboard is provided with the web plate that extends internally, and is fixed with the pipe connecting that passes web plate on the web plate, and the inner of pipe connecting is connected with pipe connecting and communicates and vertical circular row tracheae, has production well on the cylindrical surface of vapor pipe.During work, the outer end of pipe connecting feeds steam at the coking chamber initial stage of coalingging, to logical not flammable waste gas of coking middle and later periods, waste gas enters vapor pipe by pipe connecting and then enters in the space that pit kiln knife-edge sheath and stove frame surround by the production well on the vapor pipe, when the pressure in this space during more than or equal to the pressure in the coking chamber, raw gas that produces in the coking chamber and tar reduce greatly from the possibility that the fire door of pit kiln leaks outside.

All be fixed with the steel ring that is higher than steel wire upper surface 1-2mm on the inside and outside sidewall of knife-edge sheath by elastic plate.Can further increase stopping property between pit kiln knife-edge sheath and the stove frame by this kind structure design.

Be positioned at up and down the medial end of the web plate of both sides is fixed with the wear-resisting circle that cooperates with the face seal of stove frame table by elastic plate, wear-resisting circle is rolled by stainless (steel) wire and is surrounded by asbestos within it and forms, can strengthen the effect of sealing by asbestos seal, guarantee the wear resistance of asbestos simultaneously by stainless (steel) wire.

Be fixed with the wear-resisting circle contour by elastic plate on the knife-edge jacket inner wall, played multi-layer sealed effect with steel ring.

The medial end that is positioned at the web plate of the left and right sides extends a dividing plate that cooperates with front sealing around the furnace door brick, be placed with asbestos in the space that surrounds around dividing plate and the furnace door brick, can reduce product after the coking chamber internal combustion like this and enter in the space that dividing plate and furnace door brick surround.

The utility model is by having guaranteed the stopping property of knife-edge sheath and stove frame to design multi-layer sealing structure between the knife-edge sheath of coke furnace door and the stove frame, but also can produce high pressure and prevent that the raw gas that produces in the coking chamber and tar from entering in the space that knife-edge sheath and stove frame surrounded by in pipe connecting, feeding waste gas, and then ooze out from the face adapted of knife-edge sheath and stove frame, it is low also to have cost simultaneously, advantage such as changes, easy to maintenance.
