Abstract
The utility model discloses a secondary elastic sealing device for coke oven door knife edges. The secondary elastic sealing device consists of a sectional type elastic sealing plate (5), a sealing material (2), a fixing clip (1), the oven door knife edges (3) and an oven door frame (6). The secondary elastic sealing device is characterized in that one end of each oven door knife edge (3) is wrapped with the fixing clip (1), the sealing material (2) is mounted between the oven door knife edges (3) and the fixing clip (1), and the sectional type elastic sealing plate (5) is installed on the branch oven door knife edge (3) below the fixing clip (1); and the sectional type elastic sealing plate (5), the sealing material (2) and the fixing clip (1) are fixed on the oven door knife edges (3) through a tightening screw (4). By the aid of the secondary elastic sealing device, leakage of various gases of a sealing cavity can be effectively controlled, and secondary sealing of the oven door knife edges can be realized, so that the environmental pollution is reduced.
Description
Technical field
The utility model relates to a kind of tightness system, relates in particular to a kind of coking door knife-edge cross-elasticity tightness system.
Background technology
Coke furnace door seal construction is by knife-edge is installed on fire door at present, under external force, by knife-edge edge of a knife position, contact and form sealing with firedoor frame face rigidity, in installation and operation process because firedoor frame, fire door are to work under long term high temperature state, knife-edge, fire door, firedoor frame generation distortion and dedusting are unclean, cause knife-edge and firedoor frame sealing place sealing unreliable, cause deflation, smolder, cause environmental pollution.
Summary of the invention
For yielding in existing coke furnace door operational process, dedusting does not cause only can not positiver sealing deficiency, the utility model provides a kind of coke furnace door knife-edge cross-elasticity tightness system, this device is not subject to fire door knife edge, firedoor frame distortion and unclean the affecting of dedusting, and can make fire door knife edge secondary seal, reduce environmental pollution.
For achieving the above object, the utility model is realized by the following technical solutions: a kind of coking door knife-edge cross-elasticity tightness system, by sectional type resilient seal plate (5), sealer (2), retaining clip (1), fire door knife edge (3) and firedoor frame (6), formed, it is characterized by: retaining clip (1) is wrapped in of fire door knife edge (3), between fire door knife edge (3) and retaining clip (1), sealer (2) is housed, sectional type resilient seal plate (5) is arranged on retaining clip (1) minute fire door knife edge (3) below; Sectional type resilient seal plate (5), sealer (2), retaining clip (1) are fixed on fire door knife edge (3) by holding screw (4).
The beneficial effects of the utility model:
1, can effectively control the various gas leakages of annular seal space.
2, can make fire door knife edge secondary seal, reduce environmental pollution.
Accompanying drawing explanation
Fig. 1 is running status of the present utility model longitudinal section structural map.
Fig. 2 is that the utility model does not move longitudinal section structural map.
Marginal data:
1, retaining clip 2, sealer 3, fire door knife edge 4, holding screw
5, sectional type resilient seal plate 6, firedoor frame 7, annular seal space.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
In Fig. 1, sectional type resilient seal plate (5), sealer (2), retaining clip (1) are fixed on fire door knife edge (3) by holding screw (4).When fire door knife edge (3) is subject to external force to press to firedoor frame (6), sectional type resilient seal plate (5) is recoverable deformation thereupon, and the sealing plane that is adjacent to firedoor frame (6) reaches secondary seal effect.Arrow represents the pressure direction of the gas of generation in pit kiln annular seal space (7).
In Fig. 2, when fire door knife edge (3) departs from firedoor frame (6) under external force, sectional type resilient seal plate restores to the original state under elastic contribution voluntarily, and forms a pressure amount with the edge of a knife position of fire door knife edge (4).
Claims (1)
1. a coking door knife-edge cross-elasticity tightness system, by sectional type resilient seal plate (5), sealer (2), retaining clip (1), fire door knife edge (3) and firedoor frame (6), formed, it is characterized by: retaining clip (1) is wrapped in of fire door knife edge (3), between fire door knife edge (3) and retaining clip (1), sealer (2) is housed, sectional type resilient seal plate (5) is arranged on retaining clip (1) minute fire door knife edge (3) below; Sectional type resilient seal plate (5), sealer (2), retaining clip (1) are fixed on fire door knife edge (3) by holding screw (4).
