Resonant-type two-channel vibrating screen

Abstract

The invention discloses a resonant-type two-channel vibrating screen which comprises an upper screen body, a lower screen body and a screen body support. The upper screen body is located above the lower screen body and is parallel to the lower screen body, the upper screen body and the lower screen body are fixed to rotating shafts of the screen body support through connecting blocks, resonant springs are connected between the lower bottom of the upper screen body and the lower screen body, the bottom end of the outer side of the upper screen body is further provided with a connecting rod driving system, and the bottom of the screen body support is provided with damping springs. According to the resonant-type two-channel vibrating screen, an elastic driving and resonance vibration system is adopted, the condition that the energy consumption of a single-mass vibrating screen is high can be changed, the operational stability is good, the energy consumption is low, the total weight is low, the screening efficiency is high, the screening area is large, the maintenance is convenient, and the influence on foundation vibration is small.

Description

technical field [0001] The invention relates to the technical field of screening equipment widely used in mineral processing, building materials, chemical industry, light industry, metallurgy, refractory materials and other industries to classify medium and fine particle materials, in particular to a resonant double-channel vibrating screen. Background technique [0002] The traditional large-scale vibrating screening equipment is basically a single-mass vibrating equipment, especially the vibrating screen with a large screening area, which is heavy, consumes a lot of energy, and has a large dynamic load during the vibration process, which requires high rigidity of the foundation and steel structures. Great impact on the environment. Moreover, due to the large screen body, the selection of pipes and plates has large specifications, heavy weight, and inconvenient maintenance. Contents of the invention [0003] In order to solve the problems existing in the background techn...
