【摘要】：回转式烘干机因其适应性强而广泛应用于各类颗粒物料的烘干,其中三筒回转式烘干机更具优越性及广阔的市场前景,但其回转装置关键结构参数普遍存在以下问题:内筒及中筒尺寸不科学,导致烘干效率较低,流体运行阻力大,物料易堵塞;三层筒体的钢板厚度不合理,磨损不均匀,尤其外筒磨损特别严重。本文对回转装置进行了传热学、两相流运动学及三层筒体磨损规律的分析,并从工程应用角度提出了其关键结构参数的具体确定方法。
[Abstract]:The rotary dryer is widely used in the drying of all kinds of particulate materials because of its strong adaptability, among which the three-barrel rotary dryer has more advantages and broad market prospects. However, the key structural parameters of the rotary device generally have the following problems: the size of the inner cylinder and the middle cylinder is not scientific, resulting in low drying efficiency, large fluid operation resistance and easy blockage of materials; The thickness of the steel plate of the three-layer cylinder is unreasonable and the wear is uneven, especially the wear of the outer tube is especially serious. In this paper, the heat transfer, two-phase flow kinematics and the wear law of three-layer cylinder are analyzed, and the concrete determination method of its key structural parameters is put forward from the point of view of engineering application.
