1. 描述:Description
通过分析粉体剪切动态数据来描述流动行为表征,粉体工业在加工、存储、运输、料仓中常出现拱架/鼠孔结构;如压缩拱受料仓压力作用固结强度增加导致结拱;锲形拱块状物料互相啮合在孔口架桥成拱;粘结粘附拱水分、静电吸附导致粉料与仓壁粘附力增强成拱;气压平衡拱:卸料装置密封不好,导致大量空气从底部漏入仓内使料层上下气压平衡所致;在粉粒料的贮存与输送系统中,物料的流动性、物料之间及物料与固体壁面的摩擦;在料斗的设计中,排料口的大小、料斗壁的倾斜角以及粉料对料斗壁的压力,设计不合理的料斗会给生产造成很大的困难;这些影响粉体流动性的行为特征无法采用传统的测量方法来解决;本机通过测量粉体内部强度、流动函数、内部摩擦函数、密度、时间固结函数、壁面摩擦函数、粘结指数、温湿度等动态数据定量分析上述现象和状态.
The flow behavior characterization was described by
analyzing the powder shear dynamic data, The powder arch/rat hole structure is common during the
process of processing, storage, transportation, and SiloSuch as compression
arch subjected to bin pressure consolidation strength increase lead to knot the
arch, The clam shape arch material meshes with each other in the arch of the
aperture form arch.The adhesion arch adhere to moisture and electrostatic
adsorption cause the powder and the silo wall adhesion to enhance the arch.Air
pressure balance arch: the discharge device is not well sealed, causing a large
amount of air to leak from the bottom into the chamber and make the upper and
lower aire pressue balance.In the storage and delivery system of the powdery
and granular materials, the flow of material, Friction between material and
material and solid wall;In the design of hopper, The size of the discharge opening,
hopper wall slope Angle andThe pressure of the powder to the wall, unreasonable
design of hopper caused great
difficulties in production;The behavior characteristics that affect the
liquidity of the powders cannot be solved by traditional measures.This machine
by measuring the internal strength, flow function, internal friction function,
density function, Time consolidation function, wall friction, caking index,
dynamic data such as temperature and humidity in the air ,quantitative analysis
the above phenomenon and state.
