Description
Technical field
The utility model relates to the sintering machine negative pressure dust removing equipment used in metallurgy industry, particularly relates to a kind of Double-deck cinder discharge valve.
Background technique
In sintering machine coal dust proportioning, the composition change of metallurgy industry use, in the dust that head electric cleaner is collected, coal dust fails burning completely, and incendivity composition is large.The on-the-spot mode adopting automobile to draw ash transport, at any time the dust of collection can not be discharged, when dust accumulated in the time period to be unloaded in ash bucket, if there is fresh air to enter ash bucket, will make unburned completely inflammable matter burn away, ash bucket inner product ash is caused to harden, overstock in ash bucket, accumulate to positive plate, prickle wire for a long time, cause electric field ground connection, have a strong impact on electric field to run, affect dedusting environment friendly compliance rate.
Existing Double-deck cinder discharge valve comprises upper and lower two valve bodies be connected to each other, and form upper and lower two grey chambeies respectively, ingress, grey chamber separates with valve plate respectively.When unloading ash, upper valve plate is opened in advance, and the dust stratification in ash bucket enters grey chamber, and upper valve plate is closed.Now, lower valve plate is opened, and dust stratification enters lower grey chamber by upper grey chamber, then puts into chain type cinder conveyer, and dust stratification is transported into ash silo and is pulled away by automobile.In the process, in ash bucket, maintain the negative pressure state of 15kPa all the time, for isolated fresh air enters, must ensure that Double-deck cinder discharge valve has good sealing effect.
Existing XHF15 type Double-deck cinder discharge valve, feed opening diameter is 340mm, and valve plate diameter is 440mm, and the counterweight of valve plate is 19kg, directly coordinates the sealing realizing upper and lower grey chamber by valve plate with feed opening.Because onsite application is frequent, in addition the odjective cause such as burn into Long-Time Service, Double-deck cinder discharge valve can not reach satisfied sealing effect, ash bucket seriously leaks out due to unloading valve, very easily harden in ash bucket inside, all to employ a tremendous amount of manpower when overhauling at every turn and clear up, and poor at ash bucket inside processing environment, and security risk is large.
Model utility content
The technical problem that the utility model solves is: provide a kind of Double-deck cinder discharge valve, solves the problem of sealing effect difference between valve plate and feed opening.
The technical scheme in the invention for solving the above technical problem is: Double-deck cinder discharge valve, comprise upper and lower two interconnective valve bodies, the feed opening place of described body top arranges valve plate respectively, also seal ring is provided with between valve plate and feed opening, described seal ring is fixed on feed opening, valve plate is arranged the annular groove mated with seal ring.
Further, described seal ring top arranges welding plane, and welding plane is welded with feed opening; Sealing ring lower potion arranges sealing plane, and the annular groove on sealing plane and valve plate matches.
Further, the width of described welding plane is 9mm to 12mm, and the width of sealing plane is 5mm to 6mm.
Further, the diameter of described feed opening is 280mm, and described seal ring is circular, and seal ring outer diameter is 310mm, and seal ring inner diameter is 280mm, and the width of welding plane is 10mm, and the width of sealing plane is 5mm, and the diameter of described valve plate is 350mm.
Further, the material of described seal ring is cast steel, and the material of described valve plate is 16Mn.
The beneficial effects of the utility model are: arrange seal ring between feed opening and valve plate, and seal ring and valve plate contact position adopt form of grooves to coordinate, and ensure that sealing effect; Seal ring top arranges welding plane, and bottom arranges sealing plane, further ensures sealing effect; The diameter of valve plate reduces, and makes valve plate counterweight be down to 10kg, uses convenient; The choice of material cast steel of seal ring, the choice of material 16Mn of valve plate, reduces fabricating cost.The utility model improves the sealing effect between valve plate and feed opening, ensure that the operation ratio of head electric field, guarantees environment protection standard, also reduces the maintenance frequency of Double-deck cinder discharge valve.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model Double-deck cinder discharge valve comprises upper and lower two interconnective valve bodies 4, feed opening 2 place at described valve body 4 top arranges valve plate 1 respectively, seal ring 3 is also provided with between valve plate 1 and feed opening 3, seal ring 3 choice of material cast steel, seal ring 3 is circular, and seal ring 3 outer diameter is 310mm, seal ring 3 inner diameter is 280mm, as shown in Figure 4; Seal ring 3 top arranges welding plane 31, and welding plane 31 is by electric arc welding on feed opening 3, and the width of welding plane 31 is 10mm, ensure that welding quality, seal ring 3 bottom arranges sealing plane 32, and the width of sealing plane 32 is 5mm, and the cross section of seal ring 3 as shown in Figure 5; The diameter of feed opening 2 is 280mm, the diameter of valve plate 1 is 350mm, the material of valve plate 1 is 16Mn, valve plate 1 is arranged annular groove 11, annular groove 11 mates with described seal ring 3, and when valve plate 1 coordinates with seal ring 2, the sealing plane 32 of seal ring 3 snaps in annular groove 11, to realize the sealing of feed opening 2, the structure of valve plate 1 as shown in Figures 2 and 3; In addition, because the diameter of valve plate 1 reduces, make valve plate 1 counterweight drop to 10kg, use convenient.
