Adjustable joint, feeder main frame, coal breakage bucket, feeder outlet coal gate, bottom 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, can be
Coal is accurately weighed to during coal, and coal-supplying amount is automatically adjusted according to the feedback signal of combustion system, is coal-fired pot
Coal equipment is given in the advanced metering to match in stove pulverized coal preparation system with coal pulverizer.
Low speed coal mill is one of thermal power plant major pant item, includes motor, reductor, big little gear, rotation
Conveyer, cylinder, hot blast box etc. form, and are the main equipments of boiler coal dust burning preparation system.The raw coal that feeder conveying comes
Delivered to through low speed coal mill rotation conveyer lower half in 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 blast box, rotation conveyer hollow tube, and the coal dust ground is passed through into rotation
Turn the conveyer first half and be transported to the burning of boiler tissue.
Because 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 dieseling occurs in cleaning not in time.Especially when the wetter viscosity of raw coal is big, when coal pulverizer is run very
Easily there is charging tipping bucket accumulation coal slime, cause 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
Pour 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 blast anti-channeling to enter feeder, when now opening feeder inspection door, the spray of hot blast 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 blast 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, significant limitation and insecurity be present.Be mainly reflected in it is following some:(1) send 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, which sprays, hurts sb.'s feelings, and larger security risk be present;(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;(4), can not the short time when feeder breaks coal or coal bunker hole capital after selling all securities
Solve hot blast anti-channeling phenomenon, or even cause raw coal (particularly Indonesia coal class high volatile coal) is on fire burn out belt, burn run coal bin
Phenomenon.
