Abstract

The invention discloses an automatic quantitative fluidity testing device and method for powder materials, which consists of three parts: a mechanical part, a microcomputer test system hardware and software, wherein the mechanical part includes a silo, a frame, an artesian conveying part, a vibrating conveying part and Weighing platform, aiming at the natural flow of powder materials under the action of gravity and the conveying flow under the action of external force, the flow rate and flow rate change rate are determined as the dynamic evaluation index of fluidity. Velocity and flow rate of change measurement, to achieve automatic quantitative fluidity analysis of powder materials, the invention can measure the flow stability and rapidity of different powder materials, under different production environments and equipment structure materials, so as to analyze The influence of material characteristics, environmental factors, and dosing devices on the fluidity of powder materials provides theoretical basis and experimental data for the study of automatic dosing and the improvement of automatic dosing performance.

Description

technical field [0001] The invention relates to an automatic quantitative fluidity testing device and method for powdery material, which belongs to the technical field of material characteristic detection and is used for measuring the stability and rapidity of the flow of powdery material during the automatic quantitative process. Background technique [0002] In the process of automatic quantification of powder materials, operations such as conveying, feeding, weighing, filling and feeding of materials are required. Due to the variety of powder materials and the different physical and chemical properties of the materials, they show different fluidity, and the fluidity of the material will change with the different production environment, conditions and equipment structure materials. The fluidity of materials is different or changes, and the speed and stability of material delivery or feeding are different during the quantitative process, which will affect the quantitative s...
