Detecting device for evaluating segregation degree of granular materials, and detecting method

Abstract

The invention discloses a detecting device for evaluating the segregation degree of granular materials, and a detecting method. The detecting device comprises a stirring box, the side walls of the twoends of the stirring box are formed by detachable baffles which are combined, and thus the granular materials are subjected to layering segregation degree analysis conveniently; formed stirring shaftpositioning holes are used for positioning and supporting a stirring device; by forming the multiple sets of stirring shaft positioning holes, the height of the stirring device can be adjusted, so that the stirring device has different stirring modes; the stirring device is subjected to rotating control through a handle on a stirring control disc, and the granular materials are disturbed according to needs; the types of arranged stirring heads can be selected according to needs, and by selecting the stirring heads of the different types, influences of the stirring heads on material segregation are researched; arranged combined partition plates divide the stirring box into a plurality of subareas, the materials with different colors are placed into the different subareas, and thus the granular materials can be subjected to subarea segregation degree analysis; and the detecting device is simple in structure, reasonable in design and convenient to realize, use and operate.

Description

technical field [0001] The invention belongs to the field of engineering application technology, and in particular relates to an indoor detection device and a detection method for evaluating the segregation degree of granular materials. Background technique [0002] Road materials are mainly composed of granular materials, such as aggregate particles, asphalt or cement, water and other materials, of which granular materials account for 70%-80% of the overall consumption, and their state plays a vital role in the road performance of road materials. effect. Road construction includes multiple processes such as mixing, storage, transportation, paving, and rolling of materials. Granular materials may segregate at different stages, and this phenomenon has a great impact on the workability of materials and the road structure after it is formed. performance is adversely affected. For example, in the process of material mixing, the bulk material has a very complicated movement pro...

Problems solved by technology

At present, there is no definite experimental device or program to evaluate the segregation produced in different processes. Therefore, it is particularly necessary to propose an indoor detection device for evaluating the degree of segregation of granular materials.
