Abstract
The utility model relates to a sealing piece, in particular to a smoke abatement dust removing sealing gasket for a coke oven, which solves the problems that a sealing surface positioned at a smoke abatement dust removing part of the present coke oven adopts an asbestos sealing gasket or a rubber sealing gasket which have different disadvantages respectively, the service life is short, and the replacement is frequent. The smoke abatement dust removing sealing gasket adopts a metal sealing gasket which is formed by at least two metal sheets that are stacked mutually; the two adjacent metal sheets are stacked in a staggered manner or a superposition manner. The metal sealing gasket is formed by a plurality of the metal sheets which are stacked, so that the sealing gasket also has the advantages of high-temperature resistance, corrosion resistance, low probability of burnout, stable temperature variation resistance and longer service life on the premise of ensuring higher sealing effect, and can be widely applied to the sealing between a movable sealing body and a solid sealing body when smoke is reduced and dust is removed during the coaling process, or during the coke discharging process, or at a furnace door.
Description
Technical field
The utility model relates to a kind of Sealing, is specially a kind of coke oven smoke eliminating dust removing sealing gasket.
Background technique
Coke oven production is open work, in the discharging of the coke, coalingging production process, the discharging of a large amount of paroxysmal flue dust and raw coke oven gas is arranged, without gathering out reason, directly emptying, or smoke medicining dust-removing effect is not good, all can worsen production environment, the neighboring area atmosphere environment is caused the severe atmospheric pollution, so be the key of administering the coke oven exhaust gas pollutant to the collection and treatment of flue gas and dust.Need the scope of removing smoke and dust to comprise the removing smoke and dust of coalingging on the coke oven, removing smoke and dust discharge of the coke, the fire door removing smoke and dust, usually adopt at present and establish dust-removing vehicle at the coke oven furnace roof, establishing dust collector hood on coke guide is respectively applied for to collect and coalings, the pollution flue gas that the process of the discharging of the coke produces, when coalingging removing smoke and dust, just the smoke pipe (movable sealing body) of leading on the dust-removing vehicle need be docked with furnace roof dedusting mouth (fixing seal body), when carrying out the fire door removing smoke and dust or the discharging of the coke removing smoke and dust, just the extension sleeve on the dust-removing vehicle (movable sealing body) need be docked with the control of dust mouth of pipe (fixing seal body) of pusher side oven door sealing cover or the control of dust mouth of pipe (fixing seal body) of coke side dust-collecting hood of coke barrier vehicle.In the said process, overflow from joint, need set up sealing gasket in above-mentioned docking site in order to prevent flue dust, when the movable sealing body moves to the fixing seal body, make sealing gasket contact with the fixing seal body, form confined space, then flue dust is taken away, focused on, discharge.
Sealing gasket commonly used is at present made by asbestos or rubber, all there is shortcoming in actual use, though the asbestos seal pad is high temperature resistant, but elasticity is moderate, and mechanical strength is low, and sealing effect is relatively poor, though and rubber gasket elasticity and good sealing effect, but non-refractory, not anti-burning, all there is the weak point in working life in above-mentioned two kinds of sealing gaskets, changes frequent, user cost problem of higher.
Summary of the invention
The utility model adopts asbestos or rubber gasket for the sealing surface that solves existing coke oven smoke eliminating dust removing position, all has the problem that different separately shortcomings and working life are short, replacing is frequent, and a kind of coke oven smoke eliminating dust removing sealing gasket is provided.
The utility model is to adopt following technological scheme to realize: coke oven smoke eliminating dust removing sealing gasket, described sealing gasket are the metallic gaskets that is made of double layer of metal thin slice mutual superposition at least.The number of plies of sheet metal can determine that the number of plies is many more according to the requirement to sealing effect, and sealing effect is good more, and the elasticity of whole metal o-ring is also good more.This sheet metal can be the thin slice of stainless steel sheets or other metallic material.
The spread pattern of sheet metal described in the utility model has following two kinds, and the one, staggered stack can make whole metallic gasket having under the prerequisite of higher sealing effect like this between the adjacent two layers sheet metal, also has better elastic; The 2nd, overlap between the adjacent two layers sheet metal, to compare with the said structure form, its elasticity is weaker a little, but sealing effect is higher.
The utility model adopts the multilayer metal foil stack to constitute metallic gasket, guaranteeing to have under the prerequisite of higher sealing effect, can also be high temperature resistant, corrosion-resistant, easy burn-out not, cold-and-heat resistent changes stable performance, working life is longer, the sealing in the time of can being widely used in coalingging removing smoke and dust, the removing smoke and dust that discharge of the coke, fire door removing smoke and dust between movable sealing body and the sealed solid body.
Description of drawings
Fig. 1 is user mode figure of the present utility model;
Fig. 2 be among Fig. 1 A of the present utility model to structural representation one;
Fig. 3 be among Fig. 1 A of the present utility model to structural representation two;
Among the figure: the 1-sheet metal; 2-movable sealing body; 3-fixing seal body; The 4-bolt.
Embodiment
The coke oven smoke eliminating dust removing sealing gasket, sealing gasket is by double layer of metal thin slice 1 mutual superposition at least and the metallic gasket that constitutes, during concrete the making, the spread pattern of sheet metal has following two kinds, as shown in Figure 2, staggered stack between the adjacent two layers sheet metal 1, as shown in Figure 3, overlap between the adjacent two layers sheet metal 1, can adopt bolt 4 to be serially connected between each sheet metal.During installation, metallic gasket and movable sealing body can be fixed together,, make sealing gasket contact, form confined space, then flue dust be taken away, focus on, discharge with the fixing seal body when the movable sealing body moves to the fixing seal body.
Claims (3)
1. coke oven smoke eliminating dust removing sealing gasket is characterized in that described sealing gasket is by double layer of metal thin slice (1) mutual superposition at least and the metallic gasket that constitutes.
2. coke oven smoke eliminating dust removing sealing gasket according to claim 1 is characterized in that staggered stack between the adjacent two layers sheet metal (1).
3. coke oven smoke eliminating dust removing sealing gasket according to claim 1 is characterized in that overlaping between the adjacent two layers sheet metal (1).
