A vibrating sieve machine capable of displaying sieve residue and a method for measuring particle crushing

Abstract

The invention discloses a screen shaker capable of displaying the weight of screen residue and a method for measuring particle breakage. The screen shake comprises a screen and a vibrating device. Thescreen comprises a plurality of vibrating screen bodies and a fixing frame. The multiple vibrating screen bodies are fixed to the top of the vibrating device through the fixing frame and are arrangedin a laminated mode from top to bottom in the mode that the mesh diameters of screen meshes progressively decrease. Each vibrating screen body comprises a screen body, a screen wall and a hoop. The screen shake further comprises a weighing system. The weighing system comprises a measuring circuit and a display screen. Each screen wall is of a double-layer structure. The measuring circuit is arranged in interlayers of the screen walls. The display screen is mounted on the surfaces of the screen walls. The output end of the measuring circuit is electrically connected with the input end displayscreen. According to the screen shaker with the weighing function, the weight of screen residue can be directly obtained after screening is completed, the experimental workload is greatly lowered, andexperimental errors are reduced; and meanwhile, the degree of particle breakage is measured more accurately by adopting an area method, and a solving method is simpler and more practical.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a vibrating screen machine capable of displaying screen residue and a method for measuring broken particles. Background technique [0002] Granular soil materials (such as gravel soil, sandy soil, rockfill, etc.) are widely used in various fields of civil engineering, such as filling materials used in gravel roadbeds and large rockfill dams; at the same time, granular soil materials are also used as Foundation materials for various geotechnical projects such as transportation, construction, water conservancy, and ocean. The granular soil will break under the action of a certain stress level load. For example, some large rockfill dams have been built. The main reason for the large deformation of the dam is that the coarse-grained soil, which is the basic material of the dam, is redistributed under high pressure. Caused by particle breakage; the landsl...

Problems solved by technology

[0003] The current method of measuring particle crushing only measures the size of crushing from the perspective of quality, ignoring the impact of particle size on crushing. The solution process of particle crushing measured only by mass is complicated and the accuracy is low.

At the same time, the existing vibrating sieve machines can only perform sieving, and cannot directly obtain the sieve residue, and need to transfer the particles for secondary weighing. In this process, various errors will occur, which will affect the test results.
