A kind of medium-speed pulverizer, including the assembling of motor, reductor, lower frame, middle support body, separator, mill, grinding roller assembling, pressue device, drag link mechanism, hydraulic system, slag-draining device, lubricating system, basis, improvements introduced be：The shape of part grinding roller roller of milling set is centripetal circular arc bowl-type（Molded line of milling still is circular arc）, the radius of curvature of mill roll sleeve central diameter takes 0.5 times of grinding machine pitch diameter is to infinitely great multiple, good effect of the present utility model：The shape covered by changing its original roller, roller set section are changed to centripetal circular arc kidney-shaped by wheel the form of the foetus, increase the region of milling of roller set and millstone sheet, the crushing efficiency of raw coal are improved in the unit interval, so as to improve the output of coal pulverizer；The grinding roller of arc-shaped rotates along with the mill rail central diameter of mill on millstone sheet, reduces the linear velocity difference of mill roll sleeve and millstone sheet, reduces the abrasion of roller set outside left.
Description
Technical field
The utility model belongs to powder disintegrating apparatus technical field processed, and in particular to coal-fired station's coal-grinding equipment.
Background technology
The more medium-speed pulverizer used of the coal-burning utilities such as thermal power plant, including main motor, reductor, lower frame, middle frame
Body, separator, mill assembling, grinding roller assembling, pressue device, drag link mechanism, hydraulic system, slag-draining device, lubricating system, basis
Deng part.When equipment is run, main motor drives the mill being fixed on above reductor to rotate by shaft coupling, and millstone sheet is fixed
On mill, in the presence of frictional force, mill drives grinding roller rotation.Fall the raw coal on millstone sheet by separator coal spout
Milled by grinding roller, the qualified coal dust for being ground to certain fineness is sent outside mill by a hot blast by separator flour extraction pipe.
Mill part grinding roller and mill plays a part of milling and crushing to raw coal, fineness of pulverized coal is reached qualified requirement.
Roller set section in the grinding roller assembling of the wheeled coal pulverizer of conventional middling speed is evenly arranged in mill in wheel the form of the foetus, three grinding rollers
On disk watt, grinding roller falls in the mill rail central diameter of millstone sheet, and raw coal is formed between grinding roller and millstone sheet and is milled region.Coal pulverizer work
When making, it is thrown under rotation of the raw coal that coal spout is fallen in mill on millstone sheet, grinding roller falls on raw coal, in hydraulic system
Raw coal is milled under the grinding forces effect of application.By milling, modular construction is influenceed, and the raw coal amount in region of milling is relative
It is less, it have impact on the output of coal pulverizer；Simultaneously as roller set is outside larger with the linear differential of millstone sheet, grinding roller roller is added
Abrasion outside set, reduce the service life for part of milling.
Utility model content
The purpose of this utility model is to provide a kind of medium-speed pulverizer, and the shape of roll sleeve is ground by changing, is overcome existing
Coal pulverizer above shortcomings.
The utility model includes：Motor, reductor, lower frame, middle support body, separator, mill assemble, grinding roller assembles,
Pressue device, drag link mechanism, hydraulic system, slag-draining device, lubricating system, basis, the improvement done are：The mill milled in assembling
The shape of roll sleeve is tire-like, centripetal circular arc bowl-type（Molded line of milling still is circular arc）, grind roll sleeve central diameter（Pass through grinding roller roller
Cover neutral line and grind the radius at roll sleeve molded line midpoint）Radius of curvature span be coal pulverizer pitch diameter（Coal pulverizer grinds
Grind the diameter of part grinding roller and circular arc where millstone sheet contact point）0.5 times to infinitely great multiple, mills molded line and the mill of roller set
Disk watt（For arc bowl formula structure）Molded line of milling match, mill rail central diameter of the grinding roller along mill is rolled on millstone sheet.
In the utility model, the mill preferred span of roll sleeve central diameter radius of curvature is equal to coal pulverizer pitch diameter
2000 to 10000 times.
In the utility model, mill roll sleeve central diameter radius of curvature optimum valuing range is equal to coal pulverizer pitch diameter
3000 times.
The good effect of utility model is：New grinding roller assembling uses the roller set of centripetal circular arc kidney-shaped（Roller set is milled molded line
For circular arc）, molded line and the mill roll sleeve of millstone sheet match, reduce the linear velocity difference of mill roll sleeve and millstone sheet, subtract
Lack the abrasion of roller set outside left, improve the service life of easy-abrasion part.When coal pulverizer works, fall in grinding roller and mill
Milled between disk watt the area increase of effectively milling in region, make to fall the raw coal matter in region of being milled between mill roll sleeve and millstone sheet
Relative increase is measured, the crushing efficiency of raw coal is improved in the unit interval, so as to improve the output of coal pulverizer, is more beneficial for equipment operation
Stabilization.
