Abstract
The utility model discloses a device for exhaust gas discharge and automatic dust unloading. The device comprises a blower, a double-layer cinder valve and an en masse conveyor. A hinged door is provided above an outlet of the double-layer cinder valve and below an inlet of the blower. The hinged door is sealed by a sealing cover and communicates with the en masse conveyor. When dust is lower than the upper limit of the hinged door, the hinged door can automatically close through suction by means of a negative pipe pressure generated by the blower. When the dust is higher than the upper limit of the hinged door, the hinged door opens automatically under the force of gravity of the dust, and the dust is introduced into the en masse conveyor for unloading. The device is structurally simple, safe, and reliable. The device can largely extends the service life of the blower and improve economic efficiency.
Description
[technical field]
The utility model relates to plant equipment field, relates in particular to a kind of toxic emission laying dust dumping device.
[background technology]
In prior art, 1#, 2#500T sleeve kiln have a certain amount of big dust particle accumulation in toxic emission process, in production, adopt the form of regularly discharge to remove laying dust, the size of laying dust amount is to determine according to the size of lime output, the high main smoke discharging blower fan rotating speed of output is just high, discharge amount of exhaust gas is large, otherwise little.So each discharge capacity has larger difference in discharge process, and can stop up to a certain amount of rear double beat valve in inner product, it is ashless or grey peace and quiet and to cause ducted ash to continue upper long-pending that operator can think, like this, when overstocking, big dust particle too much enters main exhaust fan inside, if entering blower fan, laying dust cause fan blade impaired, fan rotor dynamic balancing loses, bearing shell is burnt in seconds, blower fan is the heart of sleeve kiln, once generation problem stops production at once, the direct losses of device damage maintenance and the indirect loss of stopping production are unable to estimate.
[summary of the invention]
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of simple in structure, safe and reliable toxic emission laying dust dumping device.
The technical solution adopted in the utility model is: a kind of toxic emission laying dust dumping device, comprise blower fan, Double-deck cinder discharge valve and burying scraper, it is characterized in that: above Double-deck cinder discharge valve outlet with below fans entrance, opening a fan hinged door, the sealed cover sealing of described hinged door also communicates with burying scraper.
[0007]the beneficial effects of the utility model are: life cycle simple in structure, safe and reliable, greatly to extend blower fan, has improved business efficiency.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model embodiment schematic diagram;
Fig. 3 is the utility model hinge schematic diagram;
1, in waste gas, carry waste gas 8, hinge 9, hinged door 10, seal closure in waste gas 7 after the bulky grain 3, burying scraper 4, Double-deck cinder discharge valve 5, blower fan 6, dedusting of particle 2, deposition, stove
11, negative pressure direction 12, dead angle
[specific embodiment]
Referring to accompanying drawing 3, a kind of toxic emission laying dust of the utility model dumping device, comprise blower fan 5, Double-deck cinder discharge valve 4 and burying scraper 3, it is characterized in that: above Double-deck cinder discharge valve 4 outlets with below fans entrance, opening a fan hinged door 9, sealed cover 10 sealings of described hinged door 9 also communicate with burying scraper 3.
When laying dust lower than hinged door 9 in limited time, the pipe negative pressure auto-pumping that hinged door 9 can rely on blower fan 5 to produce is closed, pipe negative pressure is-900mmH
2o.
While prescribing a time limit (dead angle resistance is closed) when laying dust surpasses on hinged door 9, now hinged door 9 is controlled by negative pressure no longer, upper limit alarm hinged door 9 is opened by the gravity of laying dust automatically, laying dust imports burying scraper 3 by seal closure and unloads ash, when laying dust is disposed to dead angle 12 and opens up, hinged door 9 is again subject to negative pressure and controls and automatically close.
The preferred embodiment that this utility model has been described at this, comprises that inventor is for implementing known optimal mode of the present utility model.The change of preferred embodiment is apparent for those of ordinary skills after reading above-mentioned explanation.Inventor wishes the rationally such change of application of those of ordinary skill, and inventor thinks and at this, clearly states different application and also can realize the utility model.Therefore, the utility model comprises all modifications and the equivalents of the purport of quoting in the claim of enclosing, and this allows in applicable law.In addition, any combination of all possible change of above-mentioned key element is also comprised by the utility model, unless pointed out in addition or obvious contradiction in context at this.
