Embodiment Construction

[0006] Referring to Figs. 1 and 2, this specific embodiment adopts the following technical scheme: it is composed of a vibrating screen bracket 1, a plurality of screens 2, a plurality of vibrating devices 3, and a plurality of connecting springs 4, and several screens 2 form a screen Layers, several screens 2 are lowered in turn, each screen 2 is connected with a connecting spring 4 on both sides, and the other end of the connecting spring 4 is fixed on the vibrating screen bracket 1, and each screen 2 is respectively provided with a vibrating device 3. In this specific embodiment, the vibration frequency and amplitude of each layer of vibrating screen meshes are different, and the screen openings become smaller from top to bottom, the frequency increases sequentially, and the amplitude decreases sequentially. This setting can adapt to materials of different particle sizes, improves screening efficiency and reduces screen clogging. This specific embodiment has the functions ...

Abstract

A multi-layer, multi-frequency and multi-amplitude vibration mesh grading screen relates to an industrial grading screen, in particular to a multi-layer, multi-frequency and multi-amplitude vibration mesh grading screen. The grading screen is composed of a vibration screen support (1), a plurality of screen meshes (2), a plurality of vibration devices (3) and a plurality of connecting springs (4), wherein a plurality of screen meshes form a screen mesh layer and are lowered in sequence; both sides of each screen mesh are connected with the connecting springs; the other end of each connecting spring is fixed on the vibration screen support; the vibration devices are respectively arranged on the lower surface of each screen mesh. The grading screen has multi-layer, multi-frequency and multi-amplitude functions, and has the advantages of large processing capacity, strong adaptive capacity, high sieving efficiency, low energy consumption, light complete machine weight, convenient maintenance, low operating noise and good dustproof performance.

Description

Technical field: [0001] The invention relates to an industrial grading sieve, in particular to a vibrating mesh grading sieve with multiple layers, multiple frequencies and multiple amplitudes. Background technique: [0002] In the process of vibrating screening, the material usually jumps continuously relative to the screen surface in the vibrating screen, and the material smaller than the size of the sieve hole enters the lower layer of the screen through the sieve hole during the continuous beating, so as to achieve the purpose of screening. In some occasions in the industrial production process, it is required to classify materials into different particle size ranges according to their sizes, which is the classification process of materials. The current vibrating grading sieve is to install screens with different mesh sizes, from large holes to small holes, layered on the same vibrating screen body from top to bottom, and drive the whole vibrating screen to vibrate toget...
