Description
Technical field
The utility model relates to lime shaft kiln discharging technical field, particularly relates to a kind of lime shaft kiln dual seal dumping device.
Background technology
At lime field of industrial production, the sealing dumping device under shaft furnace ash bucket mainly contains following several:
1) single-beat valve tightness system: single-beat valve tightness system is made up of individual layer seal valve and electric vibrating feeder.Electric vibrating feeder play dam, discharging effect, seal valve then seals to the feeding chute of electric vibrating feeder.
2) double-layer seal valve: double-layer seal valve is installed on the discharge opening of hopper under kiln, and its upper strata valve works the effect of damming, and lower floor's valve seals.Double beat valve is only suitable for blowing-out discharging, and its main drawback is that discharge rate is uncontrolled, and discharge quantity may be very large instantaneously.
3) three road gate valves: three road gate valves are made up of one shut off valve and two seals valve.The valve of three road gate valves is that staggered cycles opens and closes, and it second seals together with remaining in the 3rd twice valve, therefore can be used for not blowing-out continuous discharge.Three road gate valve quality too, highly large, drop into many, and still leak out after there is valve wear and fit badly problems such as leaking out, so only when large-scale shaft furnace requires to adopt just now during higher equipment because of valve.
4) star ash hoist: star ash hoist is the material discharging applying more at lime shaft kiln, can draw off material continuously under not blowing-out condition.Sealing is rely on closely cooperating of rotor and cylindrical shell, but by material weares and teares, sealing property is deteriorated at long-term operation rotor blade, and generally, the life-span of rotor is 5 ~ 6 months, and need be changed in time.
5) discharge shutter and material stock tank: discharge shutter and material stock jar structure use commonplace on MAERZ lime kiln, because two kiln thoraxes are respectively in pre-heating stage and heating phase, only the kiln thorax of the preheating when negative pressure could discharging, can not discharging during malleation, and material stock tank can not seal.
In the last few years, along with carrying forward vigorously of national energy-saving efforts at environmental protection, more and more higher to the requirement of environment protection and save energy aspect.In lime production field to this link of discharging, require that delivery device is while meeting discharging quantity, first will ensure stopping property, can not occur that dust is revealed; Next is that requirement discharging quantity is large, and the daily output of current lime shaft kiln is greater than 300 tons substantially, and normal volume should more than 600 tons; Finally to ensure the material flow trim of lime.
The growth requirement of corresponding lime shaft kiln, existing dumping device existing problems more or less, the discharging mode of single-beat valve, double-layer seal valve and discharge shutter can not be all malleation in kiln thorax, normal discharging certainly will cause the change of thermal regulation, reduces the actual production capacity of shaft furnace.Three road gate valves are not enough due to internal space, are not suitable for large-scale shaft furnace, and its spool pendulum angle is not enough, and stream can be caused to collide spool, and valve wear speed is fast.Star ash hoist is also not suitable for large-tonnage shaft furnace, and because the unit discharge quantity of equipment is too large, lime is also very large to the wearing and tearing of rotor in addition, although its sealing effectiveness is pretty good, discharging quantity cannot meet the demands.
