Vibrating screen

Abstract

The invention discloses a vibrating screen. Three vibration exciters are connected into two rectangular structures with a common side through longitudinal beams. A screen surface is arranged on the rectangular structures. The rectangular structures are connected with a frame through springs. When in operation, the rectangular structures vibrate and side plates do not vibrate. The screen surface can be a single section or a combination of a plurality of sections. The vibration amplitude, the vibration frequency, the projection angle and the vibration trajectory of each section of the screen surface can be independently adjusted, and thereby the adaptability to different materials to be screened is high. The invention has the advantages that the structure strength is high, the mass of vibration is small and the requirement of high vibration strength can be satisfied. The vibrating screen can be widely used in industries such as energy, metallurgy, ceramics, building materials, chemical industry and the like, and is mainly used for the classification of materials.

Description

technical field [0001] The invention relates to a vibrating separation device, in particular to a vibrating screen whose screen surface vibrates but side plates do not vibrate. Background technique [0002] At present, vibrating screens are widely used in energy, metallurgy, ceramics, building materials, chemical and other industries, mainly for the classification of materials. The screening effect of wet fine-grained viscous materials has been unsatisfactory. Wet fine-grained viscous materials are easy to stick together and block the screen holes. However, due to the limitation of the rigidity of the screen box, the ordinary vibrating screen has low vibration intensity and the entire screen surface The projectile strength is the same, and the material is not easy to distribute evenly on the screen surface, resulting in the wet fine-grained viscous material not having enough space and power to stratify, and not having enough time to pass through the screen.

The screening effect of wet fine-grained viscous materials has been unsatisfactory. Wet fine-grained viscous materials are easy to stick together and block the screen holes. However, due to the limitation of the rigidity of the screen box, the ordinary vibrating screen has low vibration intensity and the entire screen surface The projectile intensity is the same, and the material is not easy to distribute evenly on the screen surface, resulting in insufficient space and dynamic stratification of wet fine-grained viscous materials, and insufficient time to pass through the screen
