Abstract
A kind of blower mill striker wheel, including wheel hub, spoke, the beater plate being distributed on wheel week, improvements introduced is：Beater plate concentrates coal breakage position to have along the part that plate face outwardly protrudes towards the side of coal breakage.The good effect of the utility model is：By increasing protrusion in the key wear position of blower mill beater plate, the allowance of wearing part is increased, the formation of recess has been delayed, extend the service life of beater plate entirety, reduce beater plate and replace number, improves the working efficiency of equipment, reduce the operating cost of equipment.
Description
Technical field
The utility model belongs to machinery field, and in particular to large size with coal yard institute raw coal be milled blower mill.
Background technology
Blower mill is a kind of equipment being applied in the thermal power generation unit that burning high-moisture lignite generates electricity, warp
The raw coal for crossing high-temperature flue gas preliminarily dried enters casing internal through gate, carries out strike to it by striker wheel and is crushed, broken
After coal dust is further dried, detached through separator, qualified coal dust is admitted to boiler and burns.The striker wheel includes
Wheel hub, spoke, the beater plate being distributed on wheel week.Beater plate on striker wheel is blower mill, and to carry out strike to coal broken
Critical component and the most fast component of blower mill inter deterioration, the service life of beater plate directly affect blower mill
Time between overhauls(TBO) and unit generation amount.Beater plate wear reason on striker wheel is beaten from the shock with raw coal particle due to entering
The raw coal drop point Relatively centralized of striking wheel, for separate unit coal pulverizer, abration position is relatively fixed.Previous fan coal-grinding
Machine beater plate is all rectangle, and the side of corresponding coal breakage is equally straight line, and coal breakage position will form localized indentation because of abrasion
It falls into, beater plate is made to reduce grindability, service life, the replacement for shortening beater plate are more frequent.Influence complete machine working efficiency, material
Material expends more.
Utility model content
The purpose of this utility model is to provide a kind of blower mill striker wheel, for being crushed to coal, overcomes existing
Striker wheel above shortcomings.
The striker wheel of the utility model includes wheel hub, spoke, the beater plate being distributed on wheel week, and improvements introduced is：It beats
Hit plate concentrates coal breakage position to have along the part that plate face outwardly protrudes towards the side of coal breakage.
The good effect of the utility model is：It is protruded by increasing in the key wear position of blower mill beater plate
Portion increases the allowance of wearing part, has delayed the formation of recess, has extended the service life of beater plate entirety, reduces and beats
It hits plate and replaces number, improve the working efficiency of equipment, reduce the operating cost of equipment.
Description of the drawings
Fig. 1 is the utility model striker wheel overall structure figure.
Fig. 2 is the utility model beater plate front view.
Specific implementation mode
Refering to fig. 1, the striker wheel of Fig. 2, the utility model include wheel hub 1, spoke 2, are distributed in the beater plate 3 taken turns on week,
Improvements introduced is：Beater plate 3 concentrates coal breakage position to have the part 3-1 outwardly protruded along plate face towards the side of coal breakage.
Claims (1)
1. a kind of blower mill striker wheel, including wheel hub, spoke, the beater plate being distributed on wheel week, it is characterized in that：Described
Beater plate concentrates coal breakage position to have along the part that plate face outwardly protrudes towards the side of coal breakage.
