Abstract

The utility model discloses a cutter edge secondary sealing device for a furnace door of a coke furnace. A sealing filling (9) is arranged inside a flexible jacket (4), a spring (3) is arranged on the sealing filling (9) arranged inside the flexible jacket (4), and a guard board (7) is arranged on the outside and tightly fixed on a furnace door cutter edge (2) in screw connection mode. When a furnace door (1) is separated from a furnace doorframe (8) and does not move, the flexible jacket (4) and the sealing filling (9) tower above a cutter edge face of the furnace door cutter edge (2) for a certain distance under the action of the spring (3). When the furnace door (1) moves, the cutter point of the furnace door cutter edge (2) is attached to the surface of the furnace doorframe (8) under the action of external force, and the flexible jacket (4) and the sealing filling (9) move along with the furnace door cutter edge (2) and overcome pressure of the spring (3), and therefore local elasticity deforms to be contacted with the surface of the furnace doorframe (8), leakage of various gas in a sealing cavity (5) is further controlled, and accordingly secondary sealing of the furnace door cutter edge (2) is achieved.

Description

A kind of coke furnace door knife-edge secondary sealer

Technical field

The utility model relates to a kind of seal arrangement, relates in particular to a kind of coke furnace door knife-edge secondary sealer.

Background technique

The coke furnace door seal construction is by knife-edge is installed on the fire door at present, under external force, form once sealing by rigid contact of knife-edge edge of a knife position and firedoor frame face, be under the long term high temperature state, to work because of fire door in the running, knife-edge, fire door, firedoor frame generation distortion and dedusting are unclean, cause the sealing of knife-edge and firedoor frame sealing part unreliable, cause deflation, smolder, cause environmental pollution.

Summary of the invention

Deficiency at above-mentioned technology existence, the utility model provides a kind of coke furnace door knife-edge secondary sealer, and its flexible shroud and sealing filler neither are subjected to fire door knife-edge, firedoor frame distortion and unclean the influencing of dedusting, can make fire door knife-edge secondary seal again, reduce environmental pollution.

For achieving the above object, the technological scheme that the utility model adopted is: is made up of fire door (1), fire door knife-edge (2), spring (3), flexible shroud (4), Seal cage (5), screw (6), backplate (7), firedoor frame (8) and sealing filler (9), it is characterized by: flexible shroud (4), spring (3) and backplate (7) pass through screw (6) fixedly on the fire door knife-edge (2).Insert sealing filler (9) in the flexible shroud (4), spring (3) places on the interior sealing filler (9) of flexible shroud (4), and the outside adds backplate (7), connects with screw (6) to be anchored on the fire door knife-edge (2).

Advantage of the present utility model is: overcome in the coke furnace door running that distortion, dedusting do not cause only can not reliable sealing deficiency, make fire door knife-edge secondary seal, reduce environmental pollution.

Embodiment

The utility model is described in further detail below in conjunction with Fig. 1, Fig. 2:

In Fig. 1, flexible shroud (4), spring (3) and backplate (7) are by screw (6) fixedly on the fire door knife-edge (2).Sealing filler (9) place flexible shroud (4), when fire door (1) breaks away from firedoor frame (8) when not moving, flexible shroud (4) and sealing filler (9) are under spring (3) effect, above fire door knife-edge (2) actinal surface certain distance, when fire door (1) moves, fire door knife-edge (2) edge of a knife is adjacent to firedoor frame (8) face under external force, flexible shroud (4) and sealing filler (9) move with fire door knife-edge (2), and overcome spring (3) pressure, make it local elasticity's distortion contact furnace doorframe (8) face, further control Seal cage (5) all gases leaks, so reach the purpose of the secondary seal of fire door knife-edge (2).

In Fig. 2, when fire door (1) broke away from firedoor frame (8) under external force, sealing filler (9) restored to the original state by the effect of spring (3), and gave the pressure amount with one of the edge of a knife position formation of fire door knife-edge (2).

Claims

1. coke furnace door knife-edge secondary sealer, is made up of fire door (1), fire door knife-edge (2), spring (3), flexible shroud (4), Seal cage (5), screw (6), backplate (7), firedoor frame (8) and sealing filler (9), it is characterized by: flexible shroud (4), spring (3) and backplate (7) pass through screw (6) fixedly on the fire door knife-edge (2).

2. a kind of coke furnace door knife-edge secondary sealer according to claim 1, it is characterized by: inserted sealing filler (9) in the described flexible shroud (4), spring (3) then places on the interior sealing filler (9) of flexible shroud (4), and the outside adds backplate (7).
