Floating screen vibrating screen

Abstract

A floating screen surface vibrating screen belongs to the field of vibrating screening machinery. It solves the problems that the screen surface has no secondary vibration, the material is easy to get stuck and the screening efficiency is improved. It is mainly composed of screen frame, screen surface, vibrator, vibration damping support device and motor transmission device. The beams supporting the screen surface include fixed support beams and floating support beams, and the floating support beams are arranged between the corresponding two fixed support beams; the screen surface tensioned along the material flow, both ends are tensioned and fixed on the fixed support beams, and the middle is fixed by the fixed support beam. The floating support beam is supported and has an upward convex arc; both ends of the floating support beam are installed on the side plates of the screen frame through springs. The springs that mount the floating support beams can be rubber shear springs, composite springs or coil springs. The screen surface can be connected and combined by multiple sections of tensioned screen surface. It has the characteristics of long life and good elasticity of the screen surface, the material is not easy to get stuck and the screening efficiency is high. It can be applied to the vibrating screen for screening various materials.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a vibrating screen with a floating screen surface, which has good elasticity of the vibrating screen surface, long service life, no material jamming and high sieving rate. Background technique [0002] The vibrating screen is mainly composed of a screen box, a screen surface, a vibrator, a vibration damping support device and a motor transmission device. The motor transmission drives the vibrator to vibrate, driving the screen box and the screen surface to screen the material. The screen surface of conventional vibrating screens is generally installed on the screen frame by rigid compression or simply tension. When the vibrating screen is working, the screen surface and the screen frame are relatively immobile, the screen surface lacks elasticity during the vibration of the screen machine, and the material is easy to get stuck. When the material impacts on the ...

AI Technical Summary

Problems solved by technology

When the vibrating screen is working, the screen surface and the screen frame are relatively immovable, the screen surface lacks elasticity during the vibration of the screen machine, and the material is easy to get stuck

When the material impacts on the screen surface during the screening process, since the screen surface has no buffer function, it is easy to cause damage and shorten the life of the screen surface
