Modular reconfigurable transverse vibration large flip-flow screen

Abstract

The invention discloses a modularized reconfigurable transverse vibration large flip-flow screen which comprises a rack, a unit flip-flow screen, a feeding end material blocking device, a motor and a motor base. The unit flip-flow screen is composed of an inner screen frame, an outer screen frame, an eccentric stepped rotating shaft, a connecting rod, an eccentric belt pulley, a plate spring, an ROSTA spring, an adjustable spring support, a polyurethane screen plate and the like. The unit flip-flow screens are supported and installed on the machine frame through adjustable springs, and the proper number, installation conditions and operation working conditions of the unit flip-flow screens are selected according to the material quantity and the material property. The feeding end material blocking device is independently installed and is supported on the machine frame through a support, and the included angle between the feeding end material blocking device and the screen face is adjustable. The problem that a large flip-flow screen structure is poor in reliability is solved, and the proper screening area, the screen face inclination angle, the amplitude and the frequency can be flexibly selected according to the material quantity and the material property. The vibrating screen has the advantages of being simple in structure, high in screening efficiency, small in foundation dynamic load and capable of saving energy.

Description

technical field [0001] This paper discloses a modular reconfigurable lateral vibrating large-scale relaxation screen, which belongs to the field of screening machinery. Specifically, it is a screen area and amplitude frequency that can be adjusted according to the material feeding amount and material properties. Horizontal vibration large relaxation screen. Background technique [0002] The relaxation screen can effectively solve the difficulties encountered in the dry depth screening of sticky and wet fine particles, simplifies the technological process in the fields of metallurgy, coal washing and solid waste sorting, and reduces the processing cost. At present, the trend of large-scale screening equipment is obvious, and the large-scale equipment requires high overall stability and strong driving force of the screening machine. The bottleneck of large-scale relaxation screen is mainly the problem of structural reliability. The larger the structure of the relaxation scree...
