Relaxation sieve

Technical Field

The invention belongs to the field of material vibration screening, relates to a relaxation screen, and particularly relates to a flexible relaxation screen capable of realizing particle size classification and self-cleaning screen surface functions.

Background

The vibrating screen is widely applied to the industries of mining, smelting, chemical engineering, material processing, food processing and the like, and is used for separating loose industrial raw materials through a specific structure. The screening of general materials can be regarded as comprising four stages, namely a material static stage, wherein the material just contacts a screen and stays on the screen, and the material is compact in the stage, and the condition that small particles pass through the screen is poor; in the material loosening stage, the material starts to be loosened after several ejection movements; in the material layering stage, the loose materials pass through a screen mesh to act on the loose materials through the throwing force, gravity and the like, and the small-particle materials pass through the loose material layer and pass through gaps among large particles to reach the lowest layer of the materials; and in the material sieving stage, a large amount of small-particle materials begin to be sieved, and large-particle materials are conveyed to other flows through the screen, so that the sieving work is completed.

At present, industrial screening equipment in China is developing towards the trend of large-scale, new structure and high efficiency, but the field of the vibrating screen in China still has the defects of complex structure, easy abrasion of key parts, low working efficiency and the like. Accordingly, there is a need for an improved construction for existing shaker screens.
