三通翻板分料器的长寿化设计及离散元验证
Long life design and discrete element validation of overturn type 3-pass splitter
摘要
Abstract
The 3-pass splitter has some problems such as quick wear and short life.According to the angle of repose,a turning plate with a type of ladder swing was designed to prolong its life.The discrete element method was used to simulate the property differences between straight-swing turning plate and ladder-swing turning plate.The results show that the ladder-swing turning plate can stay accumulated materials to form a thickness of material pad and greatly reduce the impact and wear of the material flow on the swinging plate.Compared with straight-swing turning plate,the ladder-swing turning plate has got the material flow impact force value reduced to about 17.5% ,and the sliding velocity value of particles close to board is decreased to about 15.2%.The experiments verified that the ladder-swing turning plate of the overturn type 3-pass splitter has good impact re-sistance and abrasion resistance,and it is an effective method to prolong the life of overturn type 3-pass split-ter.关键词
