基于数学模型对SACT工艺中刀具角度和翻堆距离关系的探讨

Discussion on the relationship between blade angle and turning distance in SACT process based on mathematical model

在SACT工艺(污泥高温好氧堆肥发酵工艺)中,滚筒式翻堆机是实现堆体控制水分、温度和供氧的核心设备。翻抛装置是翻堆机的重要工作部件,通过控制翻抛装置中滚筒的转速及刀具的角度和布置可以控制物料的翻抛距离。通过对滚筒式翻堆机刀具及污泥的运动建立数学模型并进行分析,从而找到刀具角度和翻抛距离的关系。

In the SACT process（Super Aerobic Composting Technology）,roller-type compost turner is the core equipment to realize the control of moisture,temperature and oxygen supply.The roller is an important working part of the turner,and controlling the rotation speed of the roller,the blade angle and the arrangement of the blade can control the turning distance of the material.This paper constructs and analyzes the mathematical model of the blade and the movement of the sludge to find the relationship between the blade angle and the distance.
