Description
Technical field
The utility model is related to feeder dredger fields, and in particular to a kind of coal feeder protection system device.
Background technology
Feeder be suitable for thermal power plant coal furnace pulverized coal preparation system, comprising coal bunker outlet coal gate, top coal spout and
Adjustable joint, feeder host, coal breakage bucket, feeder outlet coal gate, lower part coal spout and adjustable joint, microcomputer control
The part such as system forms.Coal in coal store enters feeder by coal gate, is connected by the conveying metering adhesive tape inside feeder
In continuous uniformly conveying coal pulverizer, boiler performance can be improved in the range of very big load change, realize continuous uniform to coal, it can be
It is coal-fired pot to accurately being weighed to coal during coal, and coal-supplying amount is automatically adjusted according to the feedback signal of combustion system
Coal equipment is given in the advanced metering to match in stove pulverized coal preparation system with coal pulverizer.

The compositions such as conveyer, cylinder, hot wind box are the main equipments of boiler coal dust burning preparation system.The raw coal that feeder conveying comes
Sent through low speed coal mill rotation conveyer lower half to coal-grinding machine drum body, raw coal in cylinder by with the colliding of steel ball, squeeze
Pressure, grinding become coal dust；First air enters cylinder through hot wind box, rotation conveyer hollow tube, and the coal dust ground is passed through rotation
Turn the conveyer first half and be transported to the burning of boiler tissue.
Since low speed coal mill rotation conveyer auger piece can not scrape coal pulverizer charging tipping bucket region, coal pulverizer charging is oblique
Bucket easily accumulation coal dust, if cleaning will appear dieseling not in time.Especially when the wetter viscosity of raw coal is big, when coal pulverizer is run very
Charging tipping bucket accumulation coal slime is susceptible to, causes coal feeding pipe clogging.In real work, when discovery coal pulverizer mixing air compartment
Or during charging tipping bucket temperature anomaly, general stoppage in transit coal pulverizer and feeder, then open feeder port of export inspection door and carry out manually
It pours water desuperheat or dredging coal chute.
When stopping unilateral feeder maintenance, after feeder outlet coal gate is closed, certain thickness raw coal, still occurs in pressure
Plate is poorly sealed to cause coal pulverizer hot wind anti-channeling to enter feeder, when opening feeder inspection door at this time, the spray of hot wind powder easily occurs
Go out to hurt sb.'s feelings, pollute environment.In actually overhauling, open feeder port of export inspection door and emit hot wind powder to feeder outlet coal lock
Door water drenching, convenient follow-up maintenance.Therefore, open feeder port of export inspection door carry out manual priming's desuperheat or dredging coal chute or
Coal gate water drenching is exported to feeder, there are significant limitations and insecurity.It is mainly reflected in the following：(1) it sends out
It when existing coal pulverizer mixing air compartment or charging tipping bucket temperature anomaly, the short time can not stop coal pulverizer, handle abnormal, even
Cause abnormal expansion；(2) opening feeder port of export inspection door draws water pipe to pour water, and easily causes hot vapour water, hot gas and carbon monoxide
Toxic gas ejection is hurted sb.'s feelings, and there are larger security risks；(3) per treatment, operations staff need to spend more than half an hour to perform safety
Measure, but be still unavoidable from coal dust race and emit, pollute environment；It (4), can not the short time when feeder breaks coal or coal bunker hole capital after selling all securities
It solves hot wind anti-channeling phenomenon or even causes raw coal (particularly Indonesia coal class high volatile coal) is on fire burn out belt, burn run coal bin
Phenomenon.
