阐述了新型螺旋振动旧砂再生成套装置的基本原理和特点,介绍了成套装置的组成、生产使用情况和良好的效果.该再生机是利用两台对称交叉安装的振动电机所产生的螺旋振动,使砂块和砂粒振动、碰撞、摩擦而溃散和除膜再生.文中分析了再生机理和受力状态,并推导了力的表达式. The basic principles and characteristics of a new type of helical vibrating sand reclamation unit are introduced, the composition, production and use of the unit are introduced, and the good effect is achieved.This reclamation unit utilizes the helical vibration generated by two symmetrical crossed vibration motors, So that the sand and sand particles vibrate, collide, friction and collapse and remove the film regeneration.The paper analyzes the regeneration mechanism and the state of stress, and derives the force expression.
