Abstract
The invention discloses a kind of coal pulverizer emery wheels, including bowl shaped mill wheel, the hollow setting of emery wheel, emery wheel side offer grinding roller interface, and the other side offers exhaust blower air outlet, fire-bar is provided in bowl wall on the inside of the emery wheel, fire-bar ring-type is uniformly distributed, and fire-bar is connect with heater, and the seal cap sealing that fire-bar and heater are arranged by outside is arranged, gas-guide tube is provided on sealing cover, the exhaust blower being provided at gas-guide tube and air outlet is connect；Coal pulverizer is during the work time, mill squeezing effect is good, feed is in place, drying is rapid, the capacity of the adjustable air of air inspiration device, thus the case where controlling coal dust discharge, under conditions of meet the requirement of environmental protection, meet production needs, fire-bar and ventilation device effectively carry out heating, drying to the ink powder on mill, accelerate mill pressure efficiency.
Description
Technical field
The present invention relates to a kind of coal pulverizer emery wheels.
Background technique
More competitive coal pulverizer one kind is HP coal pulverizer to medium-speed pulverizer in the market both at home and abroad at present, another
For SM coal pulverizer, two kinds of coal pulverizers respectively have advantage and disadvantage.The advantages of HP coal pulverizer, is that structure is simple, operational reliability is high, inspection
Repair conveniently, downtime is short and price is relatively low；Its shortcoming is that grinding efficiency is not high enough, coal-air ratio is bigger than normal, boiler efficiency
It cannot be played completely.The advantages of SM coal pulverizer, is grinding efficiency height, and coal-air ratio is small, and coal powder density is high, SM coal pulverizer
It can ensure that boiler plays higher efficiency；Its shortcoming is that structure is relative complex, casting is more, and ventilation resistance is big, and price compares
It is higher.Therefore two kinds of coal pulverizers have certain room for improvement, but abandon its disadvantage there are no the two advantage is had both in the market
New mill type occur.
Summary of the invention
In view of the above-mentioned problems, that the present invention provides a kind of structures is effective, heating effect is good, hot wind is evenly distributed
Coal pulverizer emery wheel.
Coal pulverizer emery wheel, including bowl shaped mill wheel, the hollow setting of emery wheel, emery wheel side offer grinding roller interface, and the other side is opened
Equipped with exhaust blower air outlet, be provided with fire-bar in bowl wall on the inside of the emery wheel, fire-bar ring-type is uniformly distributed, fire-bar with plus
The seal cap sealing that heat engine connection, fire-bar and heater are arranged by outside is arranged, and is provided with gas-guide tube, gas-guide tube on sealing cover
It is connect with the exhaust blower being provided at air outlet.
Compared with prior art, coal pulverizer is had the beneficial effect that during the work time, mill squeezing effect is good, gives
Expect position, rapidly, the capacity of the adjustable air of air inspiration device is reaching to control the case where coal dust is discharged for drying
To under conditions of environmental requirement, meet production needs, fire-bar and ventilation device effectively carry out heating baking to the ink powder on mill
It is dry, accelerate mill pressure efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of coal pulverizer emery wheel of the present invention.
Specific embodiment
It is illustrated as a kind of embodiment of coal pulverizer of the present invention, including bowl shaped mill wheel, the hollow setting of emery wheel, emery wheel side opens up
There is grinding roller interface 1, the other side offers exhaust blower air outlet 2, is provided with fire-bar 3, fire-bar in bowl wall on the inside of the emery wheel
Ring-type is uniformly distributed, and fire-bar is connect with heater 4,5 sealed set of sealing cover that fire-bar and heater are arranged by outside, close
Gas-guide tube 6 is provided in capping, the exhaust blower 7 being provided at gas-guide tube and air outlet is connect.
