Compounded double-mass vibratory screening equipment

Abstract

The invention discloses compounded double-mass vibratory screening equipment. The compounded double-mass vibratory screening equipment comprises a screen box and a vibration exciter which is arrangedon the screen box as well as at least one layer of rigid screen layer and elastic screen layer which is arranged in the screen box, wherein elastic screen meshes located in the elastic screen layers are mounted on multiple groups of floated frame cross beams and screen body cross beams which are arranged in parallel and alternated manners; the two ends of the corresponding screen body cross beam are separately and fixedly connected with oppositely-arranged screen box side plates; the two ends of the corresponding floated frame cross beam separately penetrate through the oppositely-arranged screen box side plates and are fixedly connected with floating frames which are arranged on the outer side of the screen box; the floated frame cross beams are in clearance fit with the screen body crossbeams so as to realize that the elastic screen meshes are driven by the floated frame cross beams to perform flip-flow horizontally; and the floated frames are fixedly connected with the screen box side plates through multiple groups of rubber cutting springs. According to the compounded double-mass vibratory screening equipment disclosed by the invention, a vibration screening function and a flip-flow screening function can be realized conveniently; and with no additional arrangement of a power device, the problem that a bottom-layer screen mesh is easily blocked is effectively solved, and the screening efficiency and the screening function are improved; and moreover, the compounded double-mass vibratory screening equipment is relatively low in energy consumption, and has a good application value in the relevant industries.

Description

technical field [0001] The invention belongs to the technical field of vibrating screening equipment for mineral classification, and in particular relates to a compound two-mass vibrating screening equipment. Background technique [0002] Due to the good sealing performance of the vibrating screen, little dust spillage, low energy consumption, low noise and long service life of the screen, it can better meet the requirements of environmental protection and has been widely used in mining, coal, smelting, building materials, chemical and other fields. application. The vibrating screen is often in the form of a multi-layer structure. The closer to the bottom screen, the smaller the particles are, and the smaller the screen hole is, so the bottom screen may be blocked, which reduces the screening efficiency to a certain extent. At the same time, excessive accumulation of materials will cause This will cause the structure of the vibrating screen to be damaged, especially when th...

The vibrating screen is often in the form of a multi-layer structure. The closer to the bottom screen, the smaller the particles are, and the smaller the screen hole is, so the bottom screen may be blocked, which reduces the screening efficiency to a certain extent. At the same time, excessive accumulation of materials will cause Cause the structure of the vibrating screen to be damaged, especially when the water content in the material is high
