Double-mass self-synchronization elliptical vibrating screen based on motion synthesis

Abstract

The invention relates to a double-mass self-synchronization elliptical vibrating screen based on motion synthesis, mainly comprising a feeding hopper, exciting motors, an upper mass, an upper mass-supporting spring, a lower mass, a lower mass-supporting spring and a base, wherein the two exciting motors with the same mass moment are mounted at the top of the upper mass in such a way that the axes of the two exciting motors are parallel and do uniform-speed reverse rotation to generate linear vibrating motion; an exciting motor which is bridged and mounted on the lower mass also does uniform-speed rotation to generate uniform-frequency circular vibrating motion; the linear vibrating motion and the circular vibrating motion are transferred by the upper mass-supporting spring and synthesized on the upper mass and the lower mass to form the elliptical motion of the upper mass and the lower mass; and the two exciting motors on the upper mass can be bridged and mounted at the top of the upper mass or on two lateral plates of the upper mass in such a way that the axes of the two exciting motors are parallel. The invention has the advantages of great screening area, great processing capability and high screening efficiency and can satisfy the production requirements of petroleum, chemical, coal, metallurgy, and the like.

Description

technical field [0001] The invention relates to a vibrating screen used in petroleum, coal, metallurgy, chemical industry, construction and other industries, in particular to a two-mass self-synchronizing elliptical vibrating screen based on motion synthesis. Background technique [0002] At present, the vibrating screen widely used at home and abroad mainly adopts the single body. In large-scale vibrating screens, as the width of the screen box increases, the strength of the vibrating body drops sharply; the vibration on the single-mass vibrating screen is transmitted to the base through the primary vibration isolation spring, and the vibration reduction effect is poor, and the base and foundation suffer Large dynamic load. In order to facilitate the replacement of the screen, the monomass vibrating screen generally adopts a single-layer screen structure, which can only perform single-stage screening, and the separation efficiency is low. There is a two-mass vibrating scr...
