Description
Technical field
The present invention relates to lime shaft kiln discharging technical field, more particularly to a kind of lime shaft kiln with double containment discharge method and
Device.
Background technology
In lime field of industrial production, the sealing device for discharging under shaft furnace ash bucket mainly has following several：
1) individual layer valve sealing means：Individual layer valve sealing means are made up of individual layer sealing valve and electric vibrating feeder.Electricity shakes feed
Machine serve dam, discharging, sealing 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 port of hopper under kiln, and its upper strata valve, which serves, to dam, under
Layer valve seals.Double beat valve is adapted only to blowing-out discharging, and its major defect is that discharge rate is uncontrolled, and moment discharge quantity can
Can be very big.
3) three road gate valve：Three road gate valves by one of shutoff valve and two seals valve group into.The valve of three road gate valves is staggeredly to follow
Ring is opened and closed, and it second is sealed with being remained in the 3rd twice valve together with, therefore can be used for not blowing-out continuous discharge.Three road gate valve matter
Amount is too, height is big, it is more to put into, and there are problems that still leaking out after valve wear and because valve is fitted badly, thus only when
Large-scale shaft furnace requires to use just now during higher equipment.
4) star ash hoist：Star ash hoist is the material discharging for applying more in lime shaft kiln, can not stopped
Continuously material is drawn off under the conditions of wind.It is the tight fit for relying on rotor and cylinder to seal, but the rotor in long-term operating
Blade is worn and torn by material and sealing property is deteriorated, generally, and the life-span of rotor is 5~6 months, need to be changed in time.
5) discharge shutter and material stock tank：Discharge shutter and material stock jar structure on MAERZ lime kiln using commonplace, due to
Two kiln thoraxes are respectively in warm-up phase and heating period, and the kiln thorax ability discharging only preheated in negative pressure can not be unloaded during malleation
Material, material stock tank can not be sealed.
In the last few years, carrying forward vigorously with national energy-saving efforts at environmental protection, to wanting in terms of environmental protection and the saving energy
Seek more and more higher.In lime production field to this link of discharging, it is desirable to which delivery device first has to while discharging quantity is met
Ensure sealing, it is impossible to dust leakage occur；Next to that requiring that discharging quantity is big, the daily output of current lime shaft kiln is substantially greater than
300 tons, normal volume should be more than 600 tons；Finally to ensure the material flow trim of lime.
The growth requirement of correspondence lime shaft kiln, the more or less presence problem of existing device for discharging, single-beat valve, bilayer are close
Discharging in the case that the mode of envelope valve and discharge shutter all can not be malleation in kiln thorax, normal discharging certainly will cause thermal regulation
Change, reduce the actual production capacity of shaft furnace.Three road gate valves are not enough due to inner space, are not suitable for large-scale shaft furnace, and its valve
Core swing angle is not enough, and stream can be caused to collide valve element, and valve wear speed is fast.Star ash hoist is also not suitable for large-tonnage
Shaft furnace, because the unit discharge quantity of equipment is too big, abrasion of the lime to rotor is also very big in addition, although its sealing effectiveness is pretty good,
But discharging quantity can not meet requirement.
The content of the invention
The invention provides a kind of lime shaft kiln double containment discharge method and device, its discharge quantity is big, good sealing effect,
Discharging work can be also completed under shaft furnace positive pressure, its turnover panel diameter is more than 700mm, can meet 300~800 tons of stones of daily output
The production requirement of the different type lime shaft kiln of ash, and intermediate buffering storehouse is provided with a variety of volume specifications, can be according to output demand
Changed；The local cast ceramic that turnover panel is contacted with rubber seal, is remarkably improved the service life of rubber ring.
In order to achieve the above object, the present invention is realized using following technical scheme：
